A three-dimensional reactor core simulation code, MASTER has been developed as a part of ADONIS which is the Korean core design package in KAERI. CASMO-3 is used as a precedent lattice code for two-group microscopic cross section and heterogeneous formfunctions. The pin power reconstruction capability of CASMO-3/MASTER was evaluated for a validation and verification Five B&W critical experiments were selected as benchmark problems. These problems included two experiments for CE-type and three for WH-type fuel assemblies. Two of them contained gadolinia rods as burnable absorber. Comparison of the calculated pin power distributions with the measured ones demonstrate that CASMO-3/MASTER can predict the pin power distribution as well as CASMO-3/SIMULATE-3.

In order to improve e-Trade service, this paper has deduced impeding factors after review of precedent research on e-Trade and analysis of e-Trade current status. Then an empirical analysis of whether variables deduced are detrimental factors to utilization of e-Trade service has been made on the basis of a research model and relevant hypotheses. The scope of e-Trade service indicated in this paper is limited to use of uTradeHub system. Analytical results for the improvement of e-Trade service clearly indicate that the higher the impeding factor to utilization of the system integration, logistics and customs clearance, marketing and users field, the more necessary the service improvement for invigoration of e-Trade service. However, foreign exchange field does not seem to require attention because SMEs have not active will to do electronic payment through the process of electronic documents.

As reviewing of current trend on PC connection details, owing to effective stress transfer in the connection, it grow to increase that use of mechanical splices, reinforcements or welded splices, and prestressing. However such devices as reinforcement, mechanical splices entail not only more cost resulted from materials but also extra construction process so as to cause PC used method to lower competition against conventional method. Therefore more enhanced connection details which help working process simplified and construction cost reduced. In this research, as replace 9.3mm 7strand for reinforcement, it is attempt to devise connection detail which makes workability improve and confirm effective stress transfer in the region of connection. The experimental research is proceeded by partial tension test of specimen. The splice lengths of 7strand is decided to be variations. The flexural capability is verified to depend on spice length. An an appropriate splice length could be also determined as a precedent research on improving PC connection detail.

Purpose of this research wishes to present way to more safe and reliable operation way to shopping mall operation companies as well as consumerism through general utilization present condition of customers and satisfaction investigation that use internet shopping mall and establish wholesome commercial transaction order. This research draws criteria and items about success factor through each precedent research literature investigation about internet shopping mall success factor, and made up a questionnaire criteria and items that affect important internet shopping mall company's selection to college students and graduate students with learning connected with electronic commerce course. Execute pair comparison that require in AHP and analyzed priority weight about criteria and items to shopping mall company selection. As the result, Appeared that 'Credibility about internet shopping mall company's transaction' is considered most heftily by importance criteria at internet shopping mall selection. Appeared that think 'Credibility of personal information leakage prevention' most important to each criteria.

Presently, the policy base of our government focusing on the privatization of public corporation with the transfer of political power, KORAIL, one of public corporation, also can not be free from there. the policy line of our government to privatize KORAIL following the developed countries' precedent has been advocated repeatedly already since the 1990's. whenever it happened, it was true that government as well as KORAIL researched on the success or failure case of privatization in developed countries, but considering lessened pressure to the public corporation during Nor's administration, I researched on the privatization of overseas' railways to remind you of what is advantage or disadvantage. In this research, treated Japan's case which is considered one of most successful privatization story in several cases. with the result of this research, which is expected to be utilized setting the policy of privatization direction, if KORAIL tried to be privatized once again.

This research proposed the necessary capability of cyber security professional personnel for cyber security education and training. Cyber security professional personnel were required specialized capability because the curriculum of cyber security education and training is structured around practice and training. Based on the knowledge, skills, and attitudes of professors, we derive candidate capabilities and index through the results of precedent research. As a result, we derived capability such the candidate capability group as teaching qualification, expert knowledge, practical ability, lecture ability, and research ability, and detailed capability index was derived accordingly. Finally, based on the questionnaire results of the professors related to the information security, it was determined that the capability required for the cyber security education and training professional personnel were expert knowledge, practical ability, and lecture ability. Among the capabilities, executive ability means that they have to fulfil abundant executive experience due to the high proportion of practical training due to the characteristics of cyber security education and training.

Although social interest is high in relation to the provision of disease codes to games, it is still insufficient to identify the damages caused by games. The purpose of this study is to examine the research trends related to game using of preschoolers to understand the implications of the precedent researches. According to the purpose, the research period, contents, types, data collection, statistical analysis, research/investigation subjects, and academic fields of the precedent researches were examined. The subject were 69 articles published in Korea from 2010 to 2019. As a result, first, a large number of researches related to preschoolers' game using were conducted in 2010-2011, 2014-2016, and the number has decreased sharply since 2017. Second, the contents of the study were mainly about the negative influences of the game and the program development. Third, quantitative and qualitative researches were conducted evenly. Fourth, the data collection methods was mostly questionnaire and other survey methods, and statistical analysis was mostly descriptive statistics, difference verification, and regression analysis. Fifth, the study subjects were focused on preschoolers, and there were many indirect investigation through parents and teachers. Sixth, the academic fields were largely divided into educational and game fields, and there was a distinct difference in the trend of research topics between the fields. Based on the results, this study aimed to provide basic information and data that can be the basis for further research on the game using and to suggest directions for future research.
