This is a basic study of further investigating the effect of oceanographic conditons, such as bottom profile, currents, and temperature, to the fish migrating course around the set-net. The survey was held at Dojang Po, southern part of Geoje Island, from July to October in 1985. There was a sea valley of which depth was 20 to 40 meters around the set-net. Near the bottom of that sea valley, there was different current pattern to the upper layer. In the sea calm condition of July and October, the vertical profiles of current and water temperature were simple. But in rough condition of September, they were complicated because of wind tuburance.

The human anatomy is the fundamental subject which is required lots of time and efforts for medical students. But most of the oriental medical students think it little important field. And moreover they have no active attitudes in their courses. In order to improve the present situation, the results obtained from this study are as follows: 1. As a Law of Cadaver Conservation revised systemically, there's need to have enough cadavers for dissection. 2. The teaching method must be converted into the laboratory technique with the strengthening human anatomy. 3. With opening a neuroanatomy course in oriental medical curriculum, the quality of nervous system is expected to increase. 4. Under the current medical system, there's need to have discussion deeply about the histology course.

As a fundamental knowledge source in a global learning environment, it is feasible to apply the relational database management systems (RDBMS), object-oriented database management systems (OODBMS), and other traditional DBMS. However, the traditional DBMSs are not feasible in semantic knowledge/ontology representation and inference. One of the reasonable ways to overcome the limitations is the semantic web-based business support framework. Especially, in this study, we focused on the development of semantic web ontology and natural language (NL)-based inference framework. To validate the efficiency of the proposed framework, we considered a reasonable scenario for course recommendation in a university.

No one denies the importance of online courses, which provide a very important alternative, especially for students who have jobs that prevent them from attending face-to-face in traditional classes; Engagement is one of the most important fundamental variables that indicate the course's success in achieving its objectives. Therefore, the current study aims to build a model using machine learning to predict student engagement in online courses. An online questionnaire was prepared and applied to the students of Jouf University in the Kingdom of Saudi Arabia, and data was obtained from the input variables in the questionnaire, which are: specialization, gender, academic year, skills, emotional aspects, participation, performance, and engagement in the online course as a dependent variable. Multiple regression was used to analyze the data using SPSS. Kegel was used to build the model as a machine learning technique. The results indicated that there is a positive correlation between the four variables (skills, emotional aspects, participation, and performance) and engagement in online courses. The model accuracy was very high 99.99%, This shows the model's ability to predict engagement in the light of the input variables.

Elementary education is the most fundamental education phase to cultivate a minimum natural quality for basic people life. Because elementary school is a very important step to be a base of lifelong education, it has to lead students to develop a capability of information utilization and rear the ability of self-leading study. Accordingly the elementary school library must be made and managed to cope with a new environment of education and information, as well as it must be a appropriate facilities for the contents of the 7th course of study : The aim of the 7th course of study is to rear the autonomous and creative Korean who lead the age of globalization and information-oriented. It is an ideal that the school library has a separate building for itself as the general information center but it is not easy to do in our conditions. Accordingly when it Is located in a school house, it has to be at the center within easy access of other related rooms such as a classroom and school house. Therefor making a plan and designing a school building, the school library has to be considered preferentially as a main facilities in order to make a school to accept the future.

Welding is one of the most fundamental and necessary work in the industry that demand sophistication of skilled workers. This study is to introduce welding simulator as a training tool, to verify its effectiveness and to measure satisfaction of the trainees. A group of freshman students at a Korea Polytechnics College in their twenties with less experience of welding participated in the study. They were divided into two groups and took a traditional training course (comparison group) and a training course with welding simulator applied reality/haptic technology (experimental group) for same hours respectively. To evaluate training effect, a national certificate test and a survey based on Phillips' ROI (Return on Investment) methodology were conducted by the students and the college respectively. And satisfaction survey among the students based on Kirkpatrick's Four-Level Evaluation Model was also carried out. The results showed that all students in the experimental group passed the national certificate test and the ROI of the experimental group for five years were 110% higher than the comparison group. Furthermore, 25% more students in the experimental group replied "very satisfied" about the overall training course and 75% more students in the same group found that the simulation was very similar to the real welding.

Tensegrity is a relatively new sructural system (about more than 50 years old) based on the use of continuous tension-discontinuous compression. In spite of the controversial principles to define these systems, several examples of tensegrity prototypes constructed in IEDS(Institute of Environment Structure Design) are presented illustrating the feasibility of tensegrity as a lightweight structure. Of course, a much more detailed structural investigation would be necessary, but at least in order to achieve the intended purpose, it is essential to understand the structural principles and the fundamental forces of tensegrity. Once this point Is established, the characteristics of these structures are described, as well as applying them to architecture. Consequently, in this work, the patterns of basic module as well as fundamental definition are introduced. Then, the application of tensegrity to architecture has also been mentioned.

강의평가 결과에 영향을 미치는 특성변수로는 교과목 수준의 다양한 강좌특성 변수들과 수강생 수준의 다양한 인적특성 변수들이 있다. 특정 수강생은 다수의 교과목을 이수하기 때문에 다수의 교과목들은 동일한 수강생 안에 속하게 됨으로써 공유되는 특성이 있게 된다. 즉 강의평가 결과는 교과목 수준의 강좌특성 (1-수준)과 수강생 수준의 인적특성 (2-수준)에 의해 영향을 받는 다층구조 (multilevel)를 가지게 되며, 위계적 자료 특성을 가지는 복수의 분석단위의 구조가 된다. 따라서 전통적인 회귀분석에서와 같이 개별 교과목들이 독립이라는 가정을 할 수 없게 된다. 본 논문에서는 강의평가결과에 영향을 미치는 다층구조의 특성을 가진 변수들의 영향력을 보다 타당하게 분석하기 위한 방법으로 위계선형모형 (HLM; hierarchical linear model)을 이용하였다. 분석결과는 다음과 같다. 먼저 교과목 수준의 특성변수들 중에 강좌규모, 개설학년, 담당교수의 전임여부, 해당 교과목의 총 평균평점, 원어강좌 여부가 통계적으로 유의하게 강의평가 결과에 영향을 미친 것으로 나타났다. 또한 수강생 수준의 인적특성 변수들 중에는 성별, 학과계열, 대입당시 전형방법, 평균평점 등이 유의하게 강의평가 결과에 영향을 미친 것으로 나타났다.

PURPOSES : As a research to develop a cement treated base course for an airport pavement which can enhance its drainage, this paper investigated the strength, infiltration performance and durability of the pervious concrete with respect to maximum coarse aggregate sizes and compaction methods. METHODS : This study measured compressive strength, infiltration rate, continuous porosity and freeze-thaw resistance of pervious concrete specimens, which were fabricated with five different compaction methods and different maximum aggregate sizes. In addition, in order to reduce the usage of Portland cement content and to enhance environment-friendliness, a portion of the cement was replaced with Ground Granulated Blast Furnace Slag (GGBS). RESULTS: Compressive strength requirement, 5 MPa at 7 days, was met for all applied compaction methods and aggregate sizes, except for the case of self-compaction. Infiltration rate became increased as the size of aggregate increased. The measured continuous porosities varied with the different compaction methods but the variation was not significant. When GGBS was incorporated, the strength requirement was successfully satisfied and the resistance to freezing-thawing was also superior to the required limit. CONCLUSIONS: The infiltration rate increased as the maximum size of aggregate increased but considering construct ability and supply of course aggregate, its size is recommended to be 25mm. With the suggested mix proportions, the developed pervious concrete is expected to successfully meet requirements for strength, drainage and durability for cement treated base or subbase course of an airport pavement.
