In CAI, it is very important to evaluate the grade of understanding which students reach about the scope of problem which students are studying. In this paper, to find out students' learning achievement, we make students reply to test which the system presents and then lead evaluation result using fuzzy number about answer result. Besides, we define the degree of prior knowledge of studentsd as conditioned fuzzy number and use existing fuzzy accuracy production function begore the stage of using fuzzy number, Next, we apply conditioned fuzzy number to accuracy degree of answer produces by this function. Through this, we come to the conclusion that evaluation result as to the same answer result is changed according to the degree of prior knowledge about the scope which students are studying.

As the number of Chinese students in Korea has significantly increased, the problems of students' life and academic achievement has appeared obviously. Utilizing an analysis on the relationship between the life satisfaction of Chinese students in Korea and the degree of internet addiction, the purposes of this research are to improve the quality of Chinese students' life and to contribute to the growth of Chinese students in Korea. A questionnaire-type survey was conducted on 350 Chinese college students in Daegu. The results of this study are as follows: First, the used time on internet games, chat and on-line TV differs from gender, the duration of internet games and their academic performance. Second, there are significant differences by gender, Korean ability, and academic performance in the life satisfaction of Chinese students in Korea. Third, Chinese college students in Korea are more addicted in the internet than Korean or Chinese college students at their own country. Fourth, the longer playing online game, the longer watching online TV, the less communicating with the Koreans, and the less satisfying with non -study related activities, the more Chinese college students of studying in Korea are addicted in the internet.

This study analyzed whether the factors of studying resilience of high school students had a control effect on self-efficacy and academic achievements depending on the degree of stress. For this purpose, this study set the cause and effect model and the research hypothesis through literature and then conducted a survey of 292 people of high school students in G metropolitan city. The analysis of this study showed that recognition ability and communication skill, which are the factors of studying resilience, had different effects on self-efficacy and academic achievements depending on the degree of stress. It has great significance that if the stress level of the high school students is lower, self-efficacy and academic achievements are higher. Therefore, this study suggested how to inspire the academic achievements based on the results of this analysis.

컴퓨터의 보급이 보편화 되면서 컴퓨터 보유 가정이 기하급수적으로 증가되고 있다. 이로 인하여 컴퓨터로 할 수 있는 일이 늘어나고, 활용분야 역시 다양해지고 있다. 특히 과거의 교수-학습 방법과는 달리 최근에 많은 분야에서 연구되고 있는 E-러닝, ICT, 컴퓨터 활용, 인터넷 등을 접목하여 학생들의 협동심과 책임감을 요하는 협동학습에 적용하고자 하는 연구가 진행 중이다. 그런데, 협동학습의 집단은 크게 인문계열, 실업계열 고등학생 집단과 중학생 집단으로 분류한다. 따라서 본 논문에서는 컴퓨터를 활용하는 정도와 이용시간 등을 학습에 얼마만큼 도움이 되는지 분석하고, 계열별로 집단을 구분하여 학생들의 집단에서 개인의 적극성과 참여정도에 대한 영향이 집단 전체에 미치는 파급효과를 분석한다. 마지막으로 학업성취에 대한 학생들의 성적차이의 관점을 분석하고, 성별에 따른 학업성취도 차이, 주변 환경에 따른 영향력의 정도, 협동학습의 결과 학업성취도의 변화를 평가한다.

과거의 교수-학습 방법과는 달리 오늘날은 다양한 학습기자재가 개발되고 보급됨에 따라 수업에 이들 도구들이 적극적으로 활용되고 있다. 특히 최근에는 e-러닝, ICT(Information Communication Technology), 컴퓨터 활용, 인터넷 등을 접목하여 학생들의 협동심과 책임감을 요하는 협동학습에 적용하고자 하는 연구가 활발하게 진행 중이다. 협동 학습의 학업성취도는 이질집단 학생들이 모여 학습 과제를 완성하는 과정에서 성취욕이 부족하거나 학습에 의욕이 없는 학생들에게도 역할을 분담하여 책임감을 갖게 하고, 자신에게 역할이 배정되었지만 혼자서 해결할 수 없는 친구에게 도움을 주어 함께 문제해결을 하도록 하는 것이다. 따라서 본 논문에서는 학생의 컴퓨터 활용능력을 이용하여 협동 학습을 통한 학습 효과 향상과 흥미 유발 등이 학생들의 학업 성취도에 어떤 영향을 미치는지 분석하고 평가한다.

Nevertherless, a structural depression with high expense of costs-low degree of efficiency and high price of commodities-low degree of growth during the last few years. And hotel companys were doing endeavor for conquer this depression with reshuffle of the personnal system and that systematizing an enterprise and production control. Hotel has more increase personnel expenses percents than increase sold price percents so that hotel reducing cook and as result, hotel has a problem from production selling of food service because that is insufficient of cook man power. On studying this research, an importancy of cusine department in inquire hotel and an efficiency man power control of cusine department influence on hotel marketing were made use of analysis for hotel kitchen management. The result of this study is like that. First, the quality of a hotel employee is directly related to that of hotel service, which is functioned as a principle factor on which success or failure of the hotel very largely depends. Second, fair evaluation of merits. Third, cognition for job as expert. Fourth, the roles and competences of the employees were affected much by the inner or outer environmental changes surrounding the hotel enterprises. Fifth, do not underestimate an intelligent ability and will power of employee, and hotel company have to manage that the employees consult themselves about their things of department and improve with the master sense for job. Sixth, pay increase and intensive system. This system can raise the will to achievement for employee's job, and company can get many benefits from government. Seventh, the employees should be encouraged to have memberships of academic organizations, to actively participate in academic meetings, workshops, conferences, and forums in the area of job performance.

Horizon Run 5 (HR5) is a cosmological hydrodynamical simulation which captures the properties of the Universe on aGpc scale while achieving a resolution of 1kpc. This enormous dynamic range allows us to simultaneously capture the physics of the cosmic web on very large scales and account for the formation and evolution of dwarf galaxies on much smaller scales. On the back of a remarkable achievement of this, we have finished to run follow-up simulations which have 2 times larger volume than before and are expected to complementary to some limitations of previous HR simulations both for the study on the large scale features and the expansion history in a distant Universe. For these simulations, we consider the sub-grid physics of radiative heating/cooling, reionization, star formation, SN/AGN feedbacks, chemical evolution and the growth of super-massive blackholes. In order to do this project, we implemented a hybrid MPI-OpenMP version of the RAMSES code, 'RAMSES-OMP', which is specifically designed for modern many-core many thread parallel systems. These simulation successfully reproduce various observation result and provide a large amount of statistical samples of Lyman-alpha emitters and protoclusters which are important to understand the formation and expansion history of early universe. These are invaluable assets for the interpretation of current ΛCDM cosmology and current/upcoming deep surveys of the Universe, such as the world largest narrow band imaging survey, ODIN (One-hundred-square-degree Dark energy camera Imaging in Narrow band).
