SummaryAntiplatelet therapy has demonstrated significant clinical benefit in the treatment of acute coronary syndrome. However, as with any treatment strategy it has been unable to prevent all cardiovascular events. This is far from surprising when considering the complexity of arterial thrombosis and more specifically platelet physiology. This lack of treatment success has provoked the introduction of various diagnostic tests and testing platforms with the intent of guiding and optimizing clinical treatment. Such tests have resulted in the generation of clinical data that suggest suboptimal response to antiplatelet agents such as aspirin and clopidogrel.In the case of both aspirin and clopidogrel, this suboptimal response has been termed resistance. Drug resistance would imply a lack of pharmacological response that has not been specifically investigated in many of the clinical studies performed to date. Rather, the term resistance has been used to describe various facets of platelet activation and aggregation relative to the testing method. Many of these measured parameters are not addressed in the therapeutic intent of the antiplatelet drug in question.

Program Error

In this employee payroll application, if there is an error program there will be a loss for employees and the company. Losses for employees, if this application program error occurs then the salary reduction will experience delays due to the difficulty in the process of calculating employee salaries and employees will be late in receiving salaries. Losses for the company, if there is an error program in this application, the company will suffer losses if the employee wants a salary reduction quickly but the company cannot calculate quickly and accurately. In solving this problem, the authors use the black box testing method. Black box testing method is a test that sees the results of execution through test data and ensures the function of the software. Black box testing method has several testing techniques, namely Sample Testing, Boundary Value Analysis, Equivalence Partitions and others. From the testing techniques that have been mentioned, we use the Equivalence Partitions testing technique. Equivalence Partitions are tests that refer to data entry on the employee payroll application form, input will be tested and then put together based on the test function, both valid and invalid values. The expected results of this test are a payroll system for employees who are computerized, have standard rules in the process of developing the program so that it is easy to develop and maintain, and can minimize errors in processing salary calculations for employees.

Teknik pengumpulan data dilakukan dengan metode dokumentasi dan metode tes. Berdasarkan hasil penelitian diketahui persentase kesalahan penggunaan (jìnyìcí) adalah sebesar 28,4%. Kesalahan tersebut tergolong pada tingkat rendah, namun ada beberapa kesalahan yang perlu lebih diperhatikan yaitu kesalahan dalam penggunaan fungsi tata bahasa dan kesalahan dalam memahami makna. Cara membedakan penggunaan (jìnyìcí) dapat dilakukan mahasiswa dengan mempelajari fungsi tata bahasa kosakata (jìnyìcí) dan memahami makna kosakata (jìnyìcí). Solusi yang dapat dilakukan adalah mempelajari fungsi tata bahasa kosakata (jìnyìcí) secara keseluruhan dengan benar, memahami makna kosakata (jìnyìcí) secara spesifik, dan memperbanyak latihan membuat kalimat menggunakan kosakata (jìnyìcí).This study aims to identify mistake percentage in using (jìnyìcí), identify what mistakes conducted by students, determine how to differentiate the usage of (jìnyìcí), and formulate solution to reduce mistake in using (jìnyìcí). This study uses descriptive-quantitative approach. There are 25 sixth students of Mandarin Language Education Department in Universitas Negeri Semarang as population and sample. In addition, data is collected by documentation and testing method. Based on the analysis, there is 28,4% of mistake in using (jìnyìcí). This finding is categorized as low. However, there are some mistakes that need to be noted. For instance, mistake in using grammar and interpreting meaning. Furthermore, (jìnyìcí) can be differentiate by studying grammar of (jìnyìcí) and understand the meaning of (jìnyìcí). Finally, it is recommended to study the grammar of (jìnyìcí), specifically understand the meaning of (jìnyìcí) and increase the exercise to make sentences using (jìnyìcí).

Graphical Tool

The development of measuring instruments requires a specialist to know the principles of operation of advanced measuring systems. This article describes guidelines for creating a virtual appliance in LabVIEW. LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical application programming environment used as a standard tool for measuring, analyzing their data, further ma­ naging devices and objects under study. LabVIEW language is not like other programming languages. It does not create a program, but a virtual tool, designed not only for the simulation of certain processes, but also for the management of hardware and the study of real physical objects. The article deals with the task of designing application software for a specific information-measuring device, analyzes the capabilities of the LabVIEW environment for spectral analysis of various signals, outlines the basic principles and techniques of programming within the framework of the LabVIEW graphical environment during the basic stages of development. The procedure for creating a virtual device is described, which allows to evaluate the spectral composition of the signals, presents a graphical code of execution (diagram) to the program and a graphical tool interface of the virtual device. A number of basic elements used to develop the program are described. The simplicity of the graphic designs, the ease of installation on the field of the program, the clarity and readability of the program — all of which makes LabVIEW preferred over other languages of programming. In most cases, the experiment is the only source of reliable information. And the result is achieved much faster than the methods of "pure" theory. The article substantiates the effectiveness of using a development tool that allows to obtain a software product and ensure the fulfillment of all the basic functions of an automated system. Developing a software algorithm for calculating statistical parameters will help engineering students understand the order of determining spectral characteristics and their place in the structure of experimental research.

Technical Requirements

Testing repeat electronic scales with non-automatic scales technical requirements so far is fairly long if not using a calculator or computer. The aim of this research is to compare the repeatability testing method of electronic scales using methods according to the technical requirements of non-automatic scales and the Australian NMI method, both of which refer to OIML R76 in determining the validity or cancellation of electronic scales repeatability testing. This research method is done through repeat testing on 3 samples of electronic scales, then on each electronic scale 2 test methods are performed. The conclusion is that the electronic scales repeatability testing uses the non-automatic scales technical requirements method and the Australian NMI method has some differences although both refer to OIML R76. These differences include several points, namely the charge used, the method of adding additions, the formula for determining electronic scales, and different test results. The Australian NMI method is deemed to make it easier and more time efficient compared to the non-automatic weighing technical requirements method.
