This study is based on the investigation of members of the college clubs related to leisure activities and people who are working out in sports centers. In Busan, Kyung-nam, and Kyung-ju to inquire into the relation between the leisure motivation according to their life-style and satisfaction of their leisure life; to draw up some alternative for improving the quality of the leisure service industry; and to offer some fundamental data to improve the quality of life and productivity, putting spare time from the law of working 5 days a week to practical use efficiently and aggressively after the operation of the system which people work 5 days a week. The first, the leisure motivation from several types of people's life-style which affect the improvement of individual are achievement pursuit type, knowledge pursuit type, satisfaction pursuit type, safety pursuit type, health pursuit type and so on. The variables to affect self-discovery are showing-off type, health pursuit type, knowledge pursuit type. The variables to affect the purpose of healing and health appear safety pursuit type, satisfaction pursuit type, and showing-off type; the variables to have influence on sociality are satisfaction pursuit type, safety pursuit type, achievement pursuit type, showing-off type, knowledge pursuit type and so on. The second, the satisfaction about leisure life related to different types of life style is in accordance with safety pursuit type, satisfaction pursuit type, health pursuit type, achievement pursuit type, knowledge pursuit type, showing-off type. The third, the satisfaction about spending the leisure time related to the leisure motivation is under the influence of sociality, purpose of healing and health, improvement of individual, self-discovery.

妻弟와 兄夫間의 婚姻可否論

鄭光鉉 서울대학교 1966 서울대학교 論文集 Vol.12 No.-

Under the old Korea civil law, marriage between a man and his wife's sister (or between a woman and her deceased or divorced sister's husband) was deemed valid. Yet under the present Civil Code, interpretation of the law have brought about two opposing views on the matter: the one deems the marriage between a man and his wife's sister as valid and the other as invalid. The writer and most scholars hold that marriage between a man and his wife's sister as valid under the present law, while the Korean Supreme Court and some others oppose this view. This article, to begin with, states about the theoretical grounds of the two opposing interpretation of law and attempts to show that the arguments holding the marriage as invalid have no ground in a reasonable interpretation of the present Korean Civil Law, arguing that the interpretation of the present law as upholding the marrige between a man and his wife's sister is most resaonable.

Mobile nodes in ad hoc mobile networks typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper proposes a solution that allows mobile nodes to access the wired Internet and to roam from base station to base station. And we also develop the efficient method that adapts in Global MANET which can be changed over time. It is observed that we can reduce not only error detection time but also network load, thus increasing the data reception rate in Global MANET Environment.

The objectives of this study are to evaluate the pH neutralization and NO_(3)^(-), SO_(4)^(2-) adsorption according to the quantity of acid rain, particle diameter and packing height of oyster shells. Acid rain is mainly of anthropogenic origin due to the strong presence of SO_(2) and NOx gases in the atmosphere. Acid rain causes environmental damages, such as lake acidification, negative effects on the vegetation, in particular forests, changes in the chemical composition of solids and in metal mobility. Neutralization of artificial acid rain was enhanced by smaller particle diameter of powdered oyster shells and larger reaction area of packed column. At the initial 12 hours of reaction time, the pH of acid rain increased rapidly. pH neutralization was appeared the highest at the 48 hours of reaction time. The removal of NO_(3)^(-) was observed and the R3 reactor showed highest efficiency of 27.8%. But, SO_(4)^(2-) removal did not observed in this study.

In this paper, we evaluated two main QoS supporting routing protocol on wireless ad hoc network. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS support service between source and destination becoming a very important issue. Of all routing protocols, DSR and AODV are very important routing protocol in MANET. So we simulated DSR and AODV QoS Routing Protocol Through simulation evaluation tool NS(Network Simulation) based on various environments.

사각블록을 갖는 채널내의 유체운동에 관한 수치해석적 연구

정경진,김광추,이종원,김종현 慶熙大學校 레이저 工學硏究所 1994 레이저공학 Vol.5 No.-

A numerical study of fluid flow in the channel with rectangular blocks is performed by using finite volume method. SIMPLER algorithm and Power-law scheme are used for numerical scheme. Numerical computation is divided into the precomputation and the main computation. In the precomputation, driven square cavity and backward-facing step are studied, and the results are shown to agree with other numerical and experimental data. In the main computation, convergence become more slow as the Reynolds number is increased. For flow fields near blocks, the severe pressure gradient is formed near the upper-left corner, and recircular zones are formed in the front and rear of blocks and in the space of blocks. In addition, the size of the recircular zone become larger as the Reynolds number increases.

이 연구의 목적은 경도 정신지체아동의 학습된 무력감을 감소시키기 위하여 체계적인 귀인훈련를 적용함으로써 학업성취능력과 학습태도 개선에 미치는 영향을 밝히는데 있다. 연구대상은 개인용 지능검사 결과 IQ 60-75사이이고 초등학교 특수학급에서 시간제 특수교육을 받고 있는 이동 3 명으로서 신체 및 언어장애와 같은 심한 장애가 없는 아동이다. 연구결과, 귀인훈련이 오랜 학교학습상황에서 겪게 된 학습의 실패상황에서 실패원인을 「능력」에 귀인하는 아동을 「노력」 에 귀인하도록 힘으로써 아동의 「학습된 무력감」 를 감소시키는데 효과적임이 밝려졌다. 즉,뺄셈학습과제의 수행속도가 귀인훈련 후 빨라졌으며 과제에 대한 흥미도 많이 증가하였다. 또한 귀인훈련이 경도 정신지체 아동의 학습태도를 개선하였다. 귀인훈련 후 아동의 실패과제에 대한 지속시간이 많이 늘어났으며, 아울러 실패과제에 대한 불안행동이 많이 감소하였고, 주의집중이 향상되며 학습태도가 바람직히게 변화된 것으로 나타났다. 이 결과는 귀인훈련을 통해 경도 정신지체아동의 학업성취도와 학습태도에 긍정적인 변화를 가져올 수 있음이 확인되었다. The purpose of the present study is to investigate how systematic atributional training affects leaming achievements and leaming attitudes for the children with mild mental retardation through decreasing their feelings of learned helplessness. For the study, three children with mental retardation, whose 1Qs range from 60 to 75, were selected from those who were enrolled at special classes of elementary schools. They do not have physical handicapped and language problems. The procedure applied to this study focused on the changes the reason for the learning failure from "their ability" to "their lack of effort".
