Vector Graphics Essay Example for Free

Vector Graphics Essay Vector designs is the utilization of geometrical natives, for example, focuses, lines, bends, and shapes or polygon(s), which are completely founded on scientific articulations, to speak to pictures in PC illustrations. Vector, in this specific circumstance, suggests in excess of a straight line. Vector illustrations depend on pictures comprised of vectors (additionally called ways, or strokes) which lead through areas called control focuses. Every one of these focuses has an unmistakable situation on the x and y tomahawks of the work plan. Each point, also, is an assortment of database, remembering the area of the point for the work space and the heading of the vector (which is the thing that characterizes the bearing of the track). Each track can be allocated a shading, a shape, a thickness and furthermore a fill. This doesn't influence the size of the records in a significant manner since all data dwells in the structure; it depicts how to draw the vector. Same as item situated illustrations, alludes to programming and equipment that utilization geometrical equations to speak to pictures. The other technique for speaking to graphical pictures is through piece maps, in which the picture is made out of an example of specks. This is some of the time called raster designs. Projects that empower you to make and control vector designs are called draw programs, while programs that controlled piece mapped pictures are called paint programs. Vector-arranged pictures are more adaptable than bit maps since they can be resized and extended. What's more, pictures put away as vectors look better ondevices (screens and printers) with higher goals, though bit-mapped pictures consistently show up the equivalent paying little mind to a gadgets goals. Another bit of leeway of vector designs is that portrayals of pictures frequently require less memory than bit-mapped pictures do. Practically totally modern designs frameworks, including CADD frameworks andanimation programming, use vector illustrations. What's more, numerous printers (PostScriptprinters, for instance) use vector illustrations. Textual styles spoke to as vectors are called vector text styles, versatile textual styles, object-situated textual styles, and layout textual styles. Note that most yield gadgets, including speck framework printers, laser printers, and show screens, are raster gadgets (plotters are the outstanding special case). This implies all articles, even vector objects, must be converted into bit maps before being yield. The distinction between vector illustrations and raster designs, in this manner, is that vector illustrations are not converted into bit maps until the last conceivable second, after all sizes and goals have been determined. PostScript printers, for instance, have a raster picture processor (RIP) that plays out the interpretation inside the printer. In their vector structure, along these lines, designs portrayals can conceivably be yield on any gadget, with any goals, and at any size. Raster Graphics In PC designs, a raster illustrations picture, or bitmap, is a dab framework information structure speaking to a generallyrectangular lattice of pixels, or purposes of shading, distinguishable by means of a screen, paper, or other presentation medium. Raster pictures are put away in picture documents with changing configurations A bitmap relates bit-for-bit with a picture showed on a screen, for the most part in a similar arrangement utilized for capacity in the presentations video memory, or possibly as a gadget free bitmap. A bitmap is actually described by the width and stature of the picture in pixels and by the quantity of bits per pixel (a shading profundity, which decides the quantity of hues it can speak to). The printing and prepress businesses know raster designs as contones (from constant tones). The inverse to contones is line work, generally actualized as vector designs in advanced frameworks. What is the contrast among vector and raster designs? Answer: The distinction among vector and raster designs is that raster illustrations are made out of pixels, while vector illustrations are made out of ways. A raster realistic, for example, a gif or jpeg, is a variety of pixels of different hues, which together structure a picture. A vector realistic, for example, a . eps document or Adobe Illustrator? record, is made out of ways, or lines, that are either straight or bended. The information document for a vector picture contains the focuses where the ways start and end, how much the ways bend, and the hues that either fringe or fill the ways. Since vector illustrations are not made of pixels, the pictures can be scaled to be exceptionally enormous without losing quality. Raster illustrations, then again, become blocky, since every pixel increments in size as the picture is made bigger. This is the reason logos and different plans are normally made in vector design the quality will appear to be identical on a business card as it will on an announcement. Vector Graphics regularly are created utilizing drawing or outline programs (e. g. , Adobe Illustrator) and are made out of scientifically characterized geometric shapesâ€lines, items and fills. Since vectors involve both size and bearing, vector components hence are included line portions whose length speaks to greatness and whose direction in space speaks to course. Vector designs as a rule are handily adjusted inside the making application and for the most part are not influenced inconveniently by scaling (expanding or diminishing their size). Since vector components are numerically characterized, scaling basically requires alteration of their scientific areas. Nonetheless, vector records don't bolster photographic symbolism well and regularly can be risky for cross-stage trade. Vector designs normally are spared as EPS group. This makes vector illustrations perfect for logo plan. Making a vector logo is increasingly troublesome however the exertion pays for itself when the vector logo record is sent to printers or sign producers and so on. The vector logo can be scaled up or down with out losing quality and would empower smooth progress between different media. Raster Graphic Images are created by computerized picture catch gadgets: advanced scanners or computerized cameras, or by pixel altering programs (e. g. , Adobe Photoshop). Raster pictures are made out of a framework (network) or bitmap of advanced picture components (pixels). Pixels are squares or square shapes depicted as dark, white, dim or shading. Raster pictures commonly are spared as TIFF group, however can be spared as EPS also. Though transformation from vector to raster is handily practiced, raster change to vector is considerably more troublesome (and regularly is beyond the realm of imagination). Raster pictures normally are effortlessly shared across different stages, yet can be more troublesome than vector illustrations to change. Too, raster designs are affected by scaling. Making a raster logo configuration utilizing Adobe Photoshop may be perfect for web just utilization yet on the off chance that you are not kidding about marking, at that point the subsequent raster PSD logo document will be of restricted use. At the point when sent to a printer or sign creator and when they attempt to scale the raster logo, the quality break down and pixellation happens. Truly, concurred, making the raster logo structure in Photoshop would empower an originator to heap on dazzling impacts, (for example, drop shadows, slanting, obscuring and so forth). Yet, the last deliverable will have constrained employments.

Internet Privacy Essays (652 words) - Privacy, Digital Rights

Web Privacy Web Privacy For what reason would it be a good idea for me to stress over protection and security? I'm not a lawbreaker or a fear based oppressor. I have nothing to cover up. These are things that a great many people think. They likewise accept the web is substantially more secure and that their own data is just accessible to them, while this is quite off-base. There are more motivations to need to ensure your security than can be named. The significant chief is that you have a privilege to protection as long as that privilege is utilized inside the limits of the law. Looking for protection ought not cause you to feel blameworthy. Protection ought to be expected, and requested. The reasons may be as basic as safeguarding your option to communicate disliked sentiments without being exposed to oppression, or on the other hand as genuine as imparting touchy business data, uncovering charge card numbers, legitimate conversations with your bookkeeper, or stowing away your actual personality from a mystery government. Despite your reasons, protection is your right. In spite of what some overseeing bodies may need general society to accept, not each one of those worried about security and protection are programmers or psychological militants. The web gives one of the most straightforward specialized apparatuses ever managed by humanity. It is speedy, advantageous, cheap....and as unreliable as it is snappy, helpful, and modest. A message sent numerous months prior may stay on an ISP's server or as a reinforcement, and can be handily recovered by any individual who realizes how to do as such. This is data which you by and by have erased for an explanation - not to be gotten to by another person after you have gotten done with it. There have been times where data has be recovered as long as a half year after, and utilized in a legal dispute as proof. It tends to be very straightforward for somebody to block your messages or data in the event that they need it. This might be only a director of your ISP or your office organize. Or on the other hand it may be a business contender, lawful enemy, or government office, with significantly more genuine goals. There are an inexhaustible methods accessible to secure online protection. Some are huge and complex while others are amazingly straightforward. The significant truth is that a few strategies are completely ailing in security while others are basically impenetrable. It is a very regular misguided judgment that namelessness rises to security. Secrecy and protection might be connected, however their noteworthiness is very unique. Do you wonder what others think about you? Treats are accessible on specific sites, and these little documents are put on your PC and record information which frequently contains data that the client would prefer to be kept secure. Data including passwords, charge card numbers and where the client has been. There are several electronic email administrations that seem to offer secrecy. Few truly do. These incorporate names such as Hotmail, Yahoo, Excite and a lot more that could be recorded. In each of these cases, the client is permitted to make an individual username that he utilizes for his messages. Tragically, through sign-up techniques and logging, it is incredibly easy to decide your ISP, and even your actual character, at the point when you utilize these administrations. For the undeniable explanation, there is no point in squandering space managing those sorts of administrations. As the client, it is your obligation to realize that your web namelessness is as it were as secure as the administration's protection approach. You ought to consistently acquaint yourself with the use and security arrangements of any E-mail or web administration you think about utilizing. Who needs to realize what you're stating? It may be a nosey individual worker, your boss, your ISP, a rival, companion, or lawful group. Despite who needs to, it is strikingly simple for another person to peruse what you compose. It is sound judgment to secure data that you don't need others to know, and individuals ought to guarantee that they go to certain lengths to do as such. There are countless charitable associations that have practical experience in ensuring your privileges to protection. It is time all around spent to visit these destinations, as you can realize what the present laws are, what is being proposed, and what is being done to ensure security.

Livin la Vida Española (Pt. 1)

Livin’ la Vida Española (Pt. 1) ¡Buenos días! from Spain! While these festivities are going on at MIT proper, I have been in Spain for more than two weeks! I dont know how many students from Spain apply to MIT each year, but just in case someone from Spain is reading this, allow me to say that you have one beautiful country. Recap (for people who are wondering why Im in Europe right now, when there was an amazing Hunt (yes, I know, Im sad too) going on at MIT): 6. Im in Europe because of 21F.782, which is a Spanish II class that is conducted entirely in Spain = living with Spanish host families and speaking Spanish almost 24/7! 28. 21F.782 covers the entire scope of a semester-long language course, which means 3 hours of class every day (from 10 AM to 1 PM) and at least one test every day of class (we cover the equivalent of one week in normal semester schedule every day). 496. Other than the classes, theres plenty of time every day to explore Madrid, venture to other cities during the weekends, and enjoy the delicious European food. 8128. Actually, 21F.782 is definitely not the only IAP language program that exists at MIT. There are plenty of other condensed-semester IAP language courses on campus (German I takes you to Germany)! The coolest thing about an immersion program is that you are completely listening, reading, and seeing the language EVERYWHERE around you. When I took Spanish in high school, it was 50-minutes of class, and then its adiós español until the next class period. Grammar/writing was important, because even if you completely suck at listening or speaking, you can still fake it pretty well in just a language class, since its just for 50 minutes. Here, if you cant speak Spanish, then you just cant speak Spanish on the streets. Gradually, as time passes, you start finding complete sentences rolling off your tongue, and soon, youre starting to make sense of the daily newspaper, the subway announcements, and having 2-hour-long conversations with your Spanish host. Its seriously awesome. :) This had been a really refreshing break from MIT, and I think this is a really cool way to spend IAP, actually (although I am missing my first IAP at MIT). Living in Spain had taught me how to appreciate the little moments of my life, away from the stress and pressure that does sneak up on me during term. Here, life is beautiful. (and warm too!! Its around 80 degrees in Barcelona, where I just came back from. Its like what, 30 degrees in Boston? =p) Now, forgive me for being tourist-y. * Okay, I just realized that Im such a bad student and I didnt actually put up any pictures of us having class. But rest assured, we ARE having class in Spain and its not all just tourism (*guilty grin*)! :) If you want to find out more, youre welcome to read our class blog! Each student in the program is required to write 3 short entries for the blog each week, detailing their travels, as part of the program assignments. Minimum Spanish ability required. Hasta luego! =D

Dual Role Relationships Impacting The World Of Counseling

Dual Role Relationships: Impacting the World of Counseling Anna O Bannon Lindenwood University, Belleville Dual Relationships: Impacting the World of Teaching and Counseling Dual relationships play a big part in the counseling environment. Unfortunately, they transpire without notice but once those lines are crossed, it is ultimately the counselor’s responsibility to ensure proper guidelines are being followed so the client is not being exploited. Guidelines are generally adhered to if the counselor maintains professional distance and recognize the boundaries that are set in place. If the client is exploited, the counselor is faced with the task of fixing the problem and not leaving the client to find his or her way out of this situation. In all likelihood, could result in the patient having a bad experience with counseling, the counselor’s reputation being ruined, or a complaint being filed of which the counselor has to appear before the state licensing board, or in court. The origination of a dual relationships can come about without notice. However, they are very prevalent in the profession of counseling. Pierson and Piazza (1997). p. 89.

An Efficient and Practical Solution to Secure the Passwords of Smartcards Free Essays

AN EFFICIENT AND PRACTICAL SOLUTION TO SECURE THE PASSWORD OF SMARTCARD Abstraction The two peculiar security dangers on acute card-based secret word cheque in conveyed models. Keen card-based secret key verification is a standout amongst the most normally utilised security instruments to concentrate the personality of a distant client, who must keep a significant superb card and the comparison war cry to finish a fruitful confirmation with the server.The proof is by and large coordinated with a cardinal foundation convention and outputs shrewd card-based secret key verified cardinal assention. We will write a custom essay sample on An Efficient and Practical Solution to Secure the Passwords of Smartcards or any similar topic only for you Order Now We utilize two conventions as a portion of this system and they are ( 1 ) enemies with precomputed information put off in the savvy card, and ( 2 ) enemies with typical information ( as for diverse clip infinites ) put away in the astute card. The antagonistic step proposed for the security dangers and secures the conventions. List TERMS- Verification, cardinal trade, disconnected from the net and on-line vocabulary assaults Presentation Distant verification is of amazing significance to guarantee an organized waiter against revengeful distant clients in spread models. To beef up security, crisp card based war cry registry has turned with a title-holder amongst the most extraordinary avowal sections. This methodological analysis includes a waiter and a client and on a regular basis consist three phases. This phase comprise hitch phase, where the waiter issues a acute card to the client. EXISTING System In a current model, A strong and effectual client verification and cardinal assention program using acute cards. It is intended to compel assorted tempting catchs including no secret key tabular array, waiter proof, and so forth. In any instance the important limitation of is a reasonably high computation cost. This is enhanced with another proposition in by mistreating the focal points of pre-computation, i.e. , inordinate operations are finished in the disconnected from the net phase ( before the confirmation ) . It is asserted in that their program can expect logged off word mention assaults irrespective of the fact that the enigma informations put away in a savvy card is traded off. Related Work As a major facet of the security indoors dispersed models, different disposals and assets need insurance from unapproved use. Distant confirmation is the most by and large utilised scheme to concentrate the character of a distant client. This paper examines an orderly attack for formalizing clients by three elements, to be specific secret word, astute card, and biometries. A non specific and unafraid construction is proposed to redesign two-component proof to three-element verification. The alteration non merely wholly enhances the informations verification with easiness to boot secures client protection in disseminated models. Likewise, our system holds a few practice-accommodating belongingss of the basic two-component verification, which we accept is of independent investing. Inculcating false information assault is a singular genuine hazard to remote detector system, for which a enemy studies forge informations to drop conveying on blooper pick at upper degree and verve squander in theodolite hubs. In this paper, we propose a novel transportation velocity proficient helpful proof ( BECAN ) program for dividing infused false information. Taking into history the arbitrary diagram properties of detector hub organisation and the helpful bit-packed proof scheme, the proposed BECAN program can save verve by in front of agenda identifying and dividing the king of beasts ‘s portion of infused false information with minor extra operating expenses at the in theodolite hubs. Furthermore, merely a small part of infused false information demands to be checked by the sink, which accordingly by and large decreases the problem of the sink. Both conjectural and reproduction consequences are given to exhibit the viability of the proposed program every bit far as hig h dividing likeliness and verve sparing. Secret word verification has been embraced as a standout amongst the most by and large utilised agreements as a portion of system environment to screen assets from unapproved access.Recently, Lee–Kim–Yoo [ S.W. Lee, H.S. Kim, K.Y. Yoo, Improvement of Chien et Al. ‘s distant user hallmark strategy utilizing smart cards, Computer Standards A ; Interfaces 27 ( 2 ) ( 2005 ) 181–183 ] and Lee-Chiu [ N.Y. Lee, Y.C. Chiu, Improved remote hallmark strategy with smart card, Computer Standards A ; Interfaces 27 ( 2 ) ( 2005 ) 177–180 ] individually proposed a acute card based secret cardinal proof program. We demonstrate that these two programs are both capable to phony assaults gave that the informations put away in the savvy card is revealed by the enemy. We likewise suggest an enhanced program with formal security verification. Despite the fact that the acute card brings amenitiess, it similarly builds the danger on history of lost cards. When the smart card is possessed by an aggressor, the aggressor will perchance try to analyse the secret information within the smart card to infer the hallmark mechanism of the waiter and so hammer user certificates or interrupt the full hallmark system In this paper, we analyze the lost smart card onslaught from Juang et al.’s strategy [ 5 ] that proposes watchword authenticated cardinal understanding. In order to bolster the security of the full system, we mitigated some of its failings. Computer security is one of most of import issues around the universe. Most computing machine systems are utilizing watchwords for their ain hallmark or confirmation mechanisms. A robust and efficacious attack for categorization of 24 individuals who their typewriting forms were collected introduced. A additive ( LDC ) , quadratic discriminant classifier ( QDC ) and k nearest neighbor ( K-NN ) are utilized to sort users keystroke forms. After that a set of mentioned ensemble methods are adopted to cut down the mistake rate and increase the dependability of biometric hallmark system. Promising consequences have been achieved. The best mean FAR, FRR and EER parametric quantities are achieved for remarkable classifiers as 19.20 % , 0.81 % and 1.39 % severally. The province of the art public presentation consequences mean FAR, FRR and EER parametric quantities are achieved for the ensemble classifiers as 0.00 % , 0.00 % and 1.15 % severally. The comfort of 802.11-based distant entree systems has prompted unbounded organisation in the client, modern and military parts. Notwithstanding, this use is predicated on a verifiable guess of classifiedness and handiness. While the security imperfectnesss in 802.11 ‘s indispensable in private constituents have been by and large promoted, the dangers to system handiness are far less loosely increased in value. Actually, it has been proposed that 802.11 is deeply powerless to noxious disclaimer of-administration ( DoS ) assaults concentrating on its disposal and media entree conventions. This paper gives an explorative scrutiny of such802.11-particular assaults – their common sense, their adequateness and possible low-overhead execution PROPOSED SYSTEM Existing program was farther enhanced by proposed program. which demonstrates that attackers can efficaciously copy the client with old secret key and old information in the savvy card. In this manner, another program was proposed to change that imperfectness, together with a few other new belongingss, for illustration, frontward enigma and secret key altering with no coaction with the waiter. The security scrutiny made in demonstrates that the enhanced program stays procure under disconnected from the net word mention assault in the superb card bad luck instance. A alteration of bing program was as of late presented and Compared with the old program, the new program in gives the convenience of secret key altering operations and has a few attractive key belongingss. Faculties PRODUCT PRESPECTIVE Existing described a efficient user hallmark and cardinal understanding strategy utilizing smart cards. Existing strategy can be viewed as an betterment over the one proposed in, which is designed to suit a figure of desirable characteristics including no watchword tabular array, waiter hallmark, etc. But the major restriction of is a comparatively high calculation cost. This is improved with a new proposal in by working the advantages of pre-computation, i.e. , dearly-won operations are completed in the offline-phase ( before the hallmark ) . It is claimed in that their strategy can forestall offline-dictionary onslaughts even if the secret information stored in a smart card is compromised. PRODUCT FEATURES Existing strategy was farther improved by hearty strategy shows that aggressors can successfully portray the user with old watchword and old informations in the smart card. Therefore, a new strategy was proposed to repair that defect, together with several other new belongingss such as forward secretiveness and watchword altering without any interaction with the waiter. The security analysis made in indicates that the improved strategy remains unafraid under offline-dictionary onslaught in the smart-card loss instance. An betterment strategy was late introduced by hearty strategy. Compared with the old strategy, the new strategy in provides the serviceability of password-changing operations and has several desirable key belongingss. DESIGN AND IMPLEMENTATION CONSTRAINTS Constraints IN ANALYSIS Constraints as Informal Text Constraints as Operational Restrictions Constraints Integrated in Existing Model Concepts Constraints as a Separate Concept Constraints Implied by the Model Structures Constraints IN DESIGN Determination of the Involved Classs Determination of the Involved Objects Determination of the Involved Actions Determination of the Require Clauses Global actions and Constraint Realization Constraints IN IMPLEMENTATION A assorted leveled organizing of dealingss may convey approximately more categories and a more addled construction to put to death. Accordingly it is suiting to alter the assorted leveled connexion construction to an easier construction, for illustration, an established degree one. It is slightly direct to alter the formed assorted leveled theoretical account into a bipartite, degree theoretical account, consisting of categories from one position and degree dealingss on the other. Flat dealingss are favored at the outline degree for grounds of effortlessness and usage easiness. There is no personality or usefulness connected with a flat connexion. A flat connexion compares with the connexion thought of element relationship demonstrating and legion point situated systems. SYSTEM FEATURES This paper returned to the security of two secret key validated cardinal assention conventions using superb cards. While they were thought to be unafraid, we demonstrated that these conventions are faulty under their ain intuitions separately. Specifically, we considered a few kinds of enemies which were non viewed as in their lineations, e.g. , enemies with precomputed information put off in the astute card and enemies with diverse information ( as for typical clip gaps ) put away in the smartcard. These enemies speak to the possible dangers in spread models and are non the same as the usually known 1s, which we accept merit the consideration from both the scholarly universe and the concern. We likewise proposed the replies for fix the security defects. At the terminal of the twenty-four hours, our results highlight the criticality of extended security theoretical accounts and formal security scrutiny on the constellation of secret word verified cardinal assention conventions using superb cards.

Potential Causes of Medication Errors †Free Samples to Students

Question: Discuss about the Potential Causes of Medication Errors. Answer: Introduction A medication error is a preventable event which may occur because of inappropriate use of medication while the medication is under the healthcare professional control. According to Blank (2011), the medication error is the commonly reported error in the emergency department with most of the mistakes happening during the administration phase manegement. The purpose of this study is to identify practices that may improve and reduce the dosage administration errors that occur and may lead to adverse effects on the patient (Flynn, 2012). The study took three months where 75% out of the 127 nurses participated in the research, and the method that got used in the study was educational intervention. On the other hand, the Do not Interrupt approach to medication refers to the interrupts that occur when nurses are administrating medication. The study took eight weeks where 227 nurses participated in the study, and they administered 4781 medications. Therefore, the Back to Basic and Do not Int errupt approaches to medication are directly related because when interruption of the nurse occurs when she is administering medicine, this may lead to a medication error. The purpose of the Back to Basic approach study is to reduce the medication administration errors that occur often in the emergency department. Medication errors can get classified into different categories which include action-based slips, knowledge-based mistakes and memory based lapses. On this study, the Back to Basics' study involved an examination of 95 nurses based on their knowledge on medication administration procedures, the reflection of their behaviors towards recommended medication practices and their medication administration errors. The study was conducted in three months by assessment through tests, surveys and observations on the nurses' chart reviews and voluntary error reports (Blank, 2011). In the Back to Basics approach to medication, the pre-test conducted reported that 69% of the nurses achieved perfect scores while 91% achieved perfect scores in the post-test. In the post-survey, the clinicians in their specific proportions said they followed the recommended p ractice most of the time which increased in 8 of the ten survey questions. The results, however, showed that there was no significant change from the survey conducted (Blank, 2011). Moreover, the review of charts revealed little difference in total medication errors (25% and 24% respectively). It, therefore, means that the nurses scored 299 during the pre-test and 295 during the post-test. During the voluntarily reported medication errors dropped from 1.28 to 0.99 per 1000 patients (blank, 2011). Critique of the Back to Basic Approach to Medication The sample size used for the research was sufficient because majority of the nurses participated in the study where 75% out of 127 nurses participated. The time taken for the study was sufficient because it took 3 months to get the results of the study. Educational intervention got used as the dependent method for the study since it provides nurses with the required knowledge of the medication administration practices. The method of education is however not sufficient in delivering the change necessary in medication administration practices. Hence, the survey and the chart review are classified as the internal validity of the study because they provide the required emphasis that are made by the research management. Furthermore, External validity is the general method that got used for the whole study which is the educational intervention (Blank, 2011). On the other hand, the aim of the Do not Interrupt study was to divert interruptions, educate clinicians and patients and to give reminders regularly and reduce the number of interrupts that happen when nurses are administering medication. This particular study was carried out in a major teaching hospital in Adelaide (Australia) where four random wards were selected to take part in the study while the control wards got blinded in the intervention. Furthermore, the period chosen for the study was two months (8weeks), and the methods used for this approach were administering vests to the clinicians, the general survey of the participating nurses and giving educational lessons to the patient and nurses (Westbrook, 2017). After the elapse of the study period, the Do not Interrupt approach yielded that 227 nurses were administering 4781 medications. The nurses experienced 57 interruptions per 100 medication administrations, whereby 89.7% were unrelated to the task at hand (Westbrook, 2017 ). The four wards experienced a significant reduction in non-medication related interruptions from 50 interruptions per 100 medication administrations to 34 disruptions per 100 medication administrations. Despite the decrease in interruptions, the post-study survey results stated that the intervention ward nurses found the vests to be time consuming and bulky; therefore only 48% seconded the idea becoming hospital policy (Westbrook, 2017). The sample size of the research was sufficient because it comprised of 227 nurses who were able to administer 4781 medications during the eight weeks of the research. Furthermore, the time taken for the research was enough because it took 2 months for the study to get completed. One can identify the internal validity of the study as the use of vests during medication administration, the putting of strategic measures aimed at preventing interruptions and the education of nurses and patients. The external validity of the study was the randomization of four wards that were supposed to be used in the research. The method was however not seen as sufficient because only 48% of the nurses applauded it to become a hospital policy management (Westbrook, 2017). Comparison of the Two Approaches to Medication These two approaches of medication go hand in hand in that through the reduction of the number of interruptions during operations; medical personnel can focus solely on medication administration which eventually reduces the medication errors. According to Blank (2011), the Back to Basics approach improves the nurses knowledge of the recommended medication administration practices. Inadequate knowledge, incomplete information about clinical characteristics and the lack of previous patient records can result in prescribing inappropriate medications. For instance, some infants died to an overdose of heparin drugs due to the wrong labeling of the medicine and the bad packaging of the medicine which resulted to the medication error that caused the death of the infants (Anderson, 2010). Another example is when the clinician prescribes penicillin without having established whether the patient is allergic or not. This means that the Do not Interrupt approach of medication is the most signifi cant compared to the Back to Basic approach because it often happens before the medication error occurs. This means the dosage error must occur for the medication error to happen which is the Back to Basic error. Moreover, the insufficient nurse experience may lead to medication errors where the nurse does not know the required dosage for a specific drug and this may lead to wrong prescriptions that may be fatal to a patient. Therefore, when the nurse has adequate skill and experience in their particular fields such errors may be avoided because the nurse knows the required dosage a patient should take (Karavasiliadou, 2014). Furthermore, the lack of sufficient protocol regarding the arrival time of medicines to the hospital may lead to late medication administration (Karavasiliadou, 2014). Observations made indicate that the rate at which medication errors get reported as voluntary is low (Aronson, 2009). For instance, when a patient was to be given a dosage of a particular medicin e at nine in the morning, and the medication happens to arrive at eleven, it means that the dosage will happen more than two hours past the correct administration time. Though this may not have severe effects on the patient, the patient may still have minor effects due to the delay of their medication. According to Velo (2009), another factor that can lead to clinical issues is the poor legible handwriting by the nurse when prescribing medication to a patient. The nurse can use abbreviations and not write the required dosage information entirely. This shows that the prescription error must occur for the medication error to happen. This is significant in that the Do not Interrupt which is the prescription error often takes place before the Back to Basic approach happens. The Back to Basic approach is often stated as the medication error. From the article, the two approaches of medication have a relative contribution in the clinical issues that often occur because irregularity must ha ppen during medication administration so as for the medication error to occur. Therefore, the Do not Interrupt approach is the most significant approach to medication because it determines whether the medication error (Back to Basic approach) may take place. Hence, it is essential for the nurses to get regular updates regarding the medication errors that occur within their facility so that they have an understanding of the best ways in which they can administer medication. According to Svitlica (2017), it is crucial when the nurses have an understanding of the errors that occur and the importance of reporting them in case they happen. From these two papers, we can conclude that improved education and improved working conditions may help in reducing the risk of medication errors. References Anderson, P., Townsend, T., CCRN-CMC, C.
