To respond to changes in the requirements of the information and control system, it is necessary to rebuild the system with new functions and/or systems with a different architecture. In this paper, we propose a method that enables on-site technicians to perform step-wise migration from a legacy system to a target system without having to stop the whole system and without requiring advance preparation or support from a system engineer who is an expert in system design and development. Accordingly, we aimed to develop a technology for the coexistence of and cooperation between with target and legacy systems and cooperation test between heterogeneous systems. We implemented this method and evaluated its effectiveness by applying it for rebuilding a production line management system.

TSINC is a new online testing method. The acronym TSINC represents its five characteristics: Time-pressed, Sequential, Individualized, Not searchable, and Calibration-bound. Its primary feature is that it can be used to organize plagiarism-resistant online testing without human monitoring. In this paper, the logical basis of this method, its implementation details, applicable areas and limitations, test cases, and so on are reported.

A simplified safety valve simulation model is established on basis of a widely used safety valve in engineering-spring directly loading safety valve, and the relationship between the mechanic parameter of spring surface and loading is discussed according to the result of simulation analysis. The relationship of strain varying rate in spring measuring point and setting pressure varying rate of safety valve is achieved, it can be used as a online fault diagnosis criteria when setting pressure changes in working course. Furthermore, an online testing technology of safety valve is proposed. Through experiment research using traditional electric strain sensor, the relationship between measured parameters of the specific parts in the safety-valve and the experimental loading is achieved, and the online testing method is proved to be very workable.

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.

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.

Penelitian ini bertujuan untuk mengetahui besar persentase kesalahan penggunaan (jìnyìcí), mengetahui kesalahan apa saja yang dilakukan mahasiswa, menentukan cara untuk membedakan penggunaan (jìnyìcí) dan merumuskan solusi yang dapat dilakukan untuk mengurangi kesalahan penggunaan (jìnyìcí) tersebut. Pendekatan penelitian yang dilakukan adalah deskriptif kuantitatif. Populasi dan sampel pada penelitian ini adalah mahasiswa semester VI angkatan 2014 Prodi Pendidikan Bahasa Mandarin Universitas Negeri Semarang sebanyak 25 mahasiswa. 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).
