Comparative Statistic Module(CSM) provides more reliable list of significant genes to genomics researchers by offering the commonly selected genes and a method of choice by calculating the rank of each statistical test based on the average ranking of common genes across the five statistical methods, i.e. t-test, Kruskal-Wallis (Wilcoxon signed rank) test, SAM, two sample multiple test, and Empirical Bayesian test. This statistical analysis module is implemented in Perl, and R languages.

한국도로공사는 선불형 플라스틱카드를 스마트카드 형태의 선불형 전자지불카드인 하이패스플러스카드로 교체하여 사용하고 있다. 하이패스플러스카드를 전자지불에 사용하기 위해서는 하이패스플러스카드에 가치를 저장하여야 하는데 이를 수행하는 스마트카드가 LSAM이다. 또한, LSAM은 PPSAM에 의해서 가치를 저장 받거나 환불할 수 있도록 설계되어있다. 따라서, LSAM의 기능 및 보안이 철저해야 한국도로공사의 전자지불시스템이 안전하다. 본 논문은 PPSAM에 의한 LSAM의 가치저장, PPSAM에 의한 LSAM의 가치환불, 그리고, LSAM에 의한 하이패스플러스카드로의 가치저장 기능 및 보안을 시험하기 위한 시험 방법, 시험 표준항목, 그리고 시험 절차 등을 포함한 시험 모듈을 개발했다. LSAM의 기능 및 보안 시험에 관한 시험 표준항목 및 시험 검사표는 한국도로공사 규격서에 준하여 ISO 표준에 적합한 항목을 기준으로 선정했다. 본 시험 모듈은 LSAM의 기능뿐 아니라 보안성 및 적합성을 시험하였다. 시험은 한국도로공사에서 사용되는 LSAM을 이용하여 실행하였다. 시험결과에 의하면, 한국도로공사에서 사용되는 LSAM은 모든 시험 기준을 통과하여 보안성 및 기능성이 적합하다고 평가되었다.

Purpose: This study aimed to develop a nursing simulation learning module for coronavirus disease 2019 (COVID-19) patient-care and examine its effects on clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient care for nursing students. Methods: A non-equivalent control group pre- and post-test design was employed. The study participants included 47 nursing students (23 in the experimental group and 24 in the control group) from G City. A simulation learning module for COVID-19 patient-care was developed based on the Jeffries simulation model. The module consisted of a briefing, simulation practice, and debriefing. The effects of the simulation module were measured using clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient-care. Data were analyzed using χ²-test, Fisher's exact test, t-test, Wilcoxon signed-rank test, and Mann-Whitney U test. Results: The levels of clinical reasoning competence, clinical competence, and performance confidence of the experimental group were significantly higher than that of the control group, and the level of anxiety was significantly low after simulation learning. Conclusion: The nursing simulation learning module for COVID-19 patient-care is more effective than the traditional method in terms of improving students' clinical reasoning competence, clinical competence, and performance confidence, and reducing their anxiety. The module is expected to be useful for educational and clinical environments as an effective teaching and learning strategy to empower nursing competency and contribute to nursing education and clinical changes.

Information communication authority module software contains various functions and services. A software test is the only acceptance test step. Recently, however, all development steps have become important. In particular, the software acceptance step is very high, and a study of the effective use of limited time and resources on acceptance step is needed. This study examined the efficiency of the Test Design Technique for Software Test. The proposed Test Design process was applied to the domain systems of info-communication and the degree of improvement was measured. This paper establishes Software Test design process Infrastructure based on the developed software.

The Korea Research Institute of Ships and Ocean Engineering (KRISO), which is developing the core technology for the buoyancy engine of underwater gliders, has developed a test module that can vertically ascend and descend with a buoyancy engine to verify the performance of the developed buoyancy engine. The independent test module was tested in a 15 metre deep pit in the Ocean Engineering Basin to verify its ability to ascend and descend. In order to test at a shallower depth than the real sea, it was necessary to know the negative buoyancy value during descent and the time at which the buoyancy engine would be activated. To do this, we solved the equation of motion in the vertical direction to obtain these values and applied them to the tank test. To validate the usefulness of solving the equation, we also compared the depth of descent over time measured in the test with the results calculated from the solution.

In this Study, as the structure of IT module for smart phone display becomes thin to catch up with slim product trend, the reliability of display module is on the rise as a issue for product design. Especially, almost part of cellular phone should undergo thermal dissipation test. thus many manufacturers have considered design guide line using CAE and simulation for more effective usage of limited resources on the market. This test simulates the case when cellular phone slips through user's fingers while he is talking on the phone. This paper studies a thermal simulation of display module in smart phone. This design for reliability improvements are suggested on the basis of the results of FVM Analysis and display of IT module and smart phone design.

Renewable energy has become more popular with the increase in the use of solar power. Consequently, the disposal of defective and old solar panels is gradually increasing giving rise to a new problem. Furthermore, the efficiency and power output decreases with aging. Researchers worldwide are engaged in solving this problem by developing eco-module technologies that restore and reuse the solar panels according to the defect types rather than simple disposal. The eco-module technology not only solves the environmental problem, but also has economic advantages, such as extending the module life. Replacement of encapsulants contributes to a major portion of the module maintenance plan, as the degradation of encapsulants accounts for 60% of the problems found in modules over the past years. However, the current International Electrotechnical Commission (IEC) standard testing was designed for the commercialization of solar modules. As the problem caused by long-term use is not considered, this method is not suitable for the quality assurance evaluation of the eco-module. Therefore, to design a new accelerated test, this paper provides an overview of EVA degradation and comparison with the IEC and accelerated tests.

본 논문에서는 IEEE 1149.1 표준인 JTAG 기반 테스트 성능향상을 위한 Preceding instruction decoding module(PIDM)을 제안하였다. PIDM은 test access port(TAP) 명령어 디코딩과정을 TAP 제어회로(TAP-controller) 이전에 수행하여 클럭회수를 최소화하였으며 테스트 타겟 안에서 test mode select(TMS) 같은 신호를 생성할 수 있게끔 설계되었다. CORDIC 프로세서의 테스트 시뮬레이션 결과 PIDM은 non-PIDM에 비해 15% 정도의 성능향상을 나타내었으며 TAP 제어회로의 게이트 수는 기존에 비해 48% 이상 감소하였다.

In this paper, you can see the structure of data slaving software module that is in use on flight test and result of the test with the slaving. The data slaving software module has many functions, data slaving for various instrumentation systems(instrumentation radars, telemetry systems for missile, aircraft and so on), setting some slaving group for multi-target, communicating with the instrumentation systems in a far away site and sending a specific value as slaving data. This fits the requests for flight test that is being performed and improves performance of the instrumentation systems.
