This paper describes the development of an optimal maze path game as web-based game contents. Client suer using web can access and run java applet program with download of java byte code with the independence of hardware system. The optimal maze path game developed in this paper consists of random maze path generation module, selected path input module, weighted optimal path search module, and path comparison module, selected path input module, weighted optimal path search module, and path comparison module. It enhances the cognition faculty of game users with the comparison of the maze path searched by optimal path search algorithm and the selected maze path by game users.

해상 ICT의 발전과 e-Navigation 도입 및 자율운항선 도입에 따라 해상 통신망의 종류와 범위가 확장되고 있고 디지털 항로표지 서비스의 필요성이 증가하고 있다. 어선원의 고령화, 해안 배후 단지의 발전에 의한 배후광, 기상여건 및 진보된 선내 항해 장비 사용 미숙 등으로 항로표지의 시각적·전자적 인지력이 저하되어 선박 안전 운항이 담보하기 어려운 상황에서 선박의 운항 상황 및 주변 해역 운항 상황·지리적 여건을 고려한 맞춤형 가상 디지털 항로표지 서비스는 항로표지의 전자적 식별을 용이하게 하고 안전 운항 유도 서비스로 해양 사고 예방에 도움이 될 것이다. 본 연구에서는 자율운항선 대응을 위한 디지털 항로표지 서비스 및 선박 운항 상황·지리적 여건을 고려한 적극적인 맞춤형 가상 디지털 항로표지 서비스 시스템의 설계방안을 제시하였다.

The purpose of this study was to identify the variation factors of hypertension medication rate between regions and to use them as a basic data for establishment of hypertension management business plan which is customized by region. The data were collected from community health survey, National Statistics Office and National Health Insurance Corporation, and were analyzed using the geographically weighted regression. As the result of analysis, the factors that influenced the hypertension medication rate between regions were subjective recognition rate of health level, the rate of medical aid client and the number of health facility per one hundred thousand of population. According to the geographically weighted regression, the total of 230 regional regression models composed of major variables which affected the hypertension medication rate were calculated. However, this study has several limitations that the explanatory power of model is not high and others. Therefore, a follow-up study which is based on the actual data of compliance with hypertension medication will be necessary.

Focusing on the factors related to the amount of contact between young married women and their noncoresident parents and their noncoresident parents-in-law, the study hypothesized two scenarios. (1) filial piety scenario which predicts that the contact with one set of parents is not affected by accessibility of other set of parents, and (2) competition scenario which predicts that ease of contact with one set of parents inhibits contact with other set of parents. These scenarios were tested against the data from National Fertility and Family Health Survey in 1994. The regression analysis of intergenerational visits appeared to support the competition scenario : The parents-in-law and the parents seem to bs in competition for visits by young married women - distance from the parents from one side has a parallel relationship to more frequent visits with the other set of parents. This is a much more equal footing for both sides of the family than attention to filial piety would predict. although the level of support from the young generation may keep declining.

This study is aimed at researching the applicability of teaching-learning models in highschool geography class by designing the models on the basis of geographical experience the learners go through everyday life. The procedures and results of the application of the models are as followed. First, the systematization of the teaching concepts should be preceded to internalize the learners cognitive development, that is, to systemize cognitive structure. The concrete learning points of geographical concepts from the units about Migration and Population Changes are systemized with 'migration' as a higher concept, 'moving type' as basic concept, 'moving factors' as the lower concept. Everyday geographical experiences the students can go through are surveyed. Second, as preparation for the geography class, hand-outs about family-moving history and the change of the family number were used as basic material for real class teaching activity, showing the learners' general concepts are very effective as basic units which can be easily understood and accessed to. Third, with the experimental class, the geography class should secure the flexibility on the teaching-learning process. The result of applying the newly developed teaching-learning model to actual geography classes was that experimental group had higher achievement rate than the compared group with general teaching-learning model applied to. The result of analyzing students' response of the new teaching-learning model was that the students were interested and satisfied emphatically and they showed positive response in regard to practical use of the contents. Here, it is noticeable that the new teaching-learning model causes the students to be interested. But it's also found that there's no big difference in improving the students' inquisitive mind.
