Since no course is offered in the area of professional ICT(Information & Communication Technology) in the high school curriculum, high school students do not have the opportunity to learn about the ICT engineering area and the possible career paths in the field. Due to this problem, high school students are not motivated to choose ICT majors at university level, and in turn, the ICT departments are struggling to recruit qualified students. In this paper, we present an R&E (research and education) model to mitigate this problem. We also present a case study on the program following the model offered by "H" university in collaboration with a local high school. Through the program we provided high school students with design and development experiences to solve engineering problems related to the ICT area and tried to attract their attention to ICT majors. The participants of the R&E program were able to experience the systematic engineering design process, ICT tools, teamwork, and communication skills through problem solving procedures. Based on three years of observation and the survey, it was found that more than 76% of students were motivated highly by ICT and engineering majors via the program. The main contribution of the paper is that we have proposed and proved the R&E program model and applied the ICT R&E model to a program to attract qualified students to ICT majors.

최근 컴퓨팅 기술의 발전으로 3차원 복합열전달(conjugate heat transfer) 문제를 계산하는 수 치해석 기술이 어느 정도 가능해 졌지만, 실제적인 전력기기 내부의 온도분포를 수치적으로 계산하는 것은 탑재된 구성요소의 다양한 크기와 형상으로 인한 매우 복잡한 경계조건을 수반하고 조밀한 격자를 요구하기 때문에 공학적이지 않다. 이를 위하여 해석적 모델을 수립하여 전력기기 열설계를 위한 수치적 해석에 적용하는 방법이 널리 사용되고 있다. 본 연구에서는 열회로망법(Thermal Network Analysis, TNA)을 이용하여 전력기기 내부의 온도분포를 예측할 수 있는 프로그램을 개발하였다. 전류가 흘러 열이 발생하고 소산되는 주회로 성분들을 각각의 노드로 분할하는 절차를 확립하였고 열접촉저항과 주울열을 적절히 선정함으로써 실제 전류가 흐르는 회로망 내 온도분포를 계산하였다.

Soil erosion processes are affected by weather factors, such as rainfall, temperature, wind, and humidity. Among these factors, rainfall directly influences soil erosion by breaking away soil particles. The kinetic energy of rainfall and water flow caused by rain entrains and transports soil particles downstream. Therefore, in order to estimate soil erosion, it is important to accurately determine the rainfall erosivity factor(R) in RUSLE(Revised Universal Soil Loss Equation). The objective of this study is to evaluate the average annual R using 14 years(2002~2015) of 1 minute rainfall data from 55 KMA(Korea Meteorological Administration) weather stations. The R results from 1 min rainfall were compared with previous R studies using 1 h rainfall data. The determination coefficients($R^2$) between R calculated using 1 min rainfall data and annual rainfall were 0.70-0.98. The estimation of 30 min rainfall intensity from 1 min rainfall data showed better $R^2$ results than results from 1 h rainfall data. For estimation of physical spatial rain erosivity(R), distribution of annual rainfall was estimated by IDW(Inverse Distance Weights) interpolation, taking elevation into consideration. Because of the computation burden, the R calculation process was programmed using the python GUI(Graphical User Interface) tool.

The recent rapid evolution of the Internet and the increasing interest on the electronic commerce had been driven by the United States Federal Governments as strategic areas. The real meaning and effect of these technological evolution should be understood to find our right direction in current hard IMF environment wisely by analyzing the continual R&D efforts and policies of the US Federal Governments in the Information and Telecommunication areas. The typical R&D projects were the Supercomputer center program launched at 1985, HPCC program at 1992, NII project at 1993, and CIC R&D program at 1996 which were increasing in scale and budget. This paper will explain the overall key R&D efforts and policies of US Federal Governments in the industrial, science and technologies, and Information and Telecommunications areas as well as the background, concepts, and effect of 1996 Telecommunication Act as a deregulation efforts.

The purpose of this study is to provide basic data for developing future ethics education programs by surveying healthcare providers working at institutions of various sizes, using Ethical Issues in Clinical Practice tool. Data were collected from 149 healthcare providers working at medical institutions in G-do. Analysis was done using t-test, ANOVA, Pearson correlation coefficient, and Multiple regression with IBM SPSS WIN/21.0. Needs for ethics education was inversely correlated to end-of-life treatment issues (r=-.22, p=.007) and patient care issues (r=-.28, p<.001). The most influential factor on the subjects' needs for ethics education was patient care issues (β=-.246, p=.035), followed by Buddhism (β=.208, p=.010). The explanatory power was 13.4% (F=5.596, p<.001). Therefore, when organizing the contents of ethics education program, patient care issues should be included to meet the needs of the subjects. Also, a customized program regarding the subjects' religion is necessary.

Recently, HAZOP has been used as one of the most effective way of qualitative risk assessment for plant industries. However, this technique requires much man labor to be successfully performed. This fact enables the adequate HAZOP worksheet program to help speeding up the procedure and managing the data of analysis. Based on the experience of HAZOP carrying out, the authors focused the purpose of this study on developing a useful and comfortable HAZOP worksheet program. The unique characteristics of developed program are the menu window expressed in common steps of HAZOP, versatile edit functions, and search menu for investigating the scenario data. The tendency analysis for existing HAZOP results was performed to validate the usefulness of the developed program.

This study investigated the purpose of commissioned on-board training and the legal basis for the management of commissioned on-board trainees, focusing on the seafarer educational institution belonging to the Ministry of Education, which cultivates merchant mariners. A program was developed based on this research. Despite the legal basis for the management of commissioned on-board trainees, satisfaction with on-board training management has not been high, and the on-board trainee management system of the university was poor. As a result safety accidents among commissioned on-board trainees occurred on ships, and a few students abandoned on-board training. An I.M.S.A.R. model has been developed for safe and systematic management of commissioned on-board trainees, and a base for a human resource management program for commissioned on-board trainees has also been developed. This study is meaningful in that it derived a practical plan for the management of commissioned on-board trainees.

This study is to seek measures for streamlining the evaluation system by analyzing the examples of advanced countries. This study was conducted, based on the relevant government policy documents and previous research papers, in the manner of comparing and analyzing the issues and cases regarding the government evaluation system of public-funded R&D programs in selected countries. In Korea, a national R&D performance evaluation system was introduced by law in 2006. In United States, Obama government has enhanced government performance management by signed into law the GPRA Modernezation Act of 2010. The Japanese Government issued a newly revised Guideline on National R&D Evaluation in late 2012. European Union has also been constantly updating its evaluation system for Framework Programmes(FPs) begun since 1984. This study gets some insights from the recent development of R&D evaluation in the other countries. It is important for the government R&D evaluation system to be in line with national S&T policy and agency's mission. In micro views, specific evaluation approaches and methods by types of various R&D programs should be more illustratively developed. Additionally it is suggested to monitor recent trends and techniques on R&D evaluation by participating in activities to communicate and share their knowledge and experiences in international evaluation research networks.

The objective of this study was to the effects of depression, anxiety and stress on the aggression among depressed adults. Subjects are 91 depressed adults in D city. The structured and self-reported questionnaires were administered to subjects and IBM SPSS 21.1 program were performed for data analysis. All of aggression and depression(r=.62, p<.001), aggression and anxiety(r=.58, p<.001), aggression and stress(r=.62, p<.001) showed positive correlation. Depression affects the aggression that is significant explanatory variables(42.3%). The findings suggested that depressed adult's aggression for managing psychological management programs with interventions seem to be necessary.
