The adolescents are called a wandering generation. Due to rapid social changes, their view of value was confused and their sense of orientation was blurred. Under these circumstances the youths feel a complicated psychology and a strong antagonism. The older generation lacks in understanding why the youths are wandering about, why their needs aren't satisfactorily met, and what they are angry at, while the younger generation doesn't find the way how they enable the older one to understand their situation and how they can get some help from the latter. A gap in a conversation between the two generations……Generation Gap……gradua11y widens. That's why the adolescent's problems are neglected. But the understanding of the younger's intricate and subtle psychology will surely help prevent them from showing anti-social tendencies, such as juvenile delinquencies and other crimes. To help a youth foster a well-balanced personality with the healthy mental hygiene is the chief goal of education, and also the responsibilities of the adults. In those respects, it is 'RECREATION' that plays a leading role in fostering a sound, cheerful, and sociable personality of the adolescents.

본 연구는 낙동강 하구 일대의 생태계 변화와 생태 관련자료를 GIS DB로 구축하고 생태지도를 작성하였다. 생태지도 작성을 위해 1984년 11월 21일, 1997년 5월 17일에 촬영된 공간해상도 30m의 Landsat TM 위성영상과 국립지리원에서 발행된 1:25,000 수치지형도, 부산시에서 조사한 생물현황 자료를 바탕으로 DB를 구축하였다. 생태지도를 작성하기 위해, 첫째, 낙동강 하구 생태계 조사 보고서와 현재까지 진행된 생태지도에 대한 문헌 연구, 둘째, 시계열적 토지피복분류도 제작, 셋째, 동·식물상, 수질 등 생태계 항목별 BB 구축과 3단계 방식에 의한 생태계 평가, 최종적으로는 이러한 분석 결과를 바탕으로 생태계 관리를 위한 생태지도를 작성하였다. This study developed an ecological mapping technique with GIS database using the analyses of existing ecological survey reports and the change detection on the Nakdong river estuary. The data which are used to establish GIS DB include 2 Landsat TM images on Nov. 31, 1984 and May 17, 1997, 1:25, 000 topographical maps established by National Geography Institution and various ecological survey reports published by Busan metropolitan city government. The details for producing ecological map are as follows. At first, the current methods of ecomapping efforts and previous ecological surveys of Nakdong river estuary were carefully examined. Secondly, the land cover maps were created from the classified Landsat images of 1984 and 1997 for the spatiotemporal ecosystem analysis. Thirdly, the ecosystem was evaluated by using GIS ecological database based on the criteria of botany, zoology and water quality etc. Each criteria was reclassified into 3 stages which describe the overall quality of ecological condition. At last, the comprehensive ecological map was suggested as a prototype of ecosystem assesment and management tool with the discussion of further study. The findings of this study would be a milestone for preserving and managing the ecosystem.

This study was designed to evaluate the effects of opioid receptor agonists on the spontaneous alternation behaviour in an animal model of obsessivecompulsive disorder in rats. According to the theory that dopamine is related to the biological etiology of obsessive-compulsive disorder, the effect of the nalbuphine(opioid kappa agonist) and the tramadol(opioid mu agonist), which act as manipulating agents on the inhibition or stimulation of dopamine release, in the spontaneous alternation behaviour were evaluated. 24 hours prior to the experiment, rats were food-deprived. These rats were put into the T-maze, in which white and black goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose the one of the goal boxes for each time. After identifying the stable baseline of spontaneous alternation behaviour, nonselective 5-HT agonist 5-MeODMT(1.25mg/kg/IP) disrupted spontaneous alternation. Rats were stratified into fluoxetine(10mg/kg/IP), nalbuphine(10mg/kg/IP), tramadol(46.4mg/kg/IP), and saline(0.5cc/IP) injection group with experimental drug treatment for 21 days. The effects on the 5-MeODMT(1.25mg/kg/IP) induced disruption of spontaneous alternation behaviour were checked at the next day of discontinuation of drug treatment. The results were as follows ; 1) At the day after 21 days of the drug treatment, the nalbuphine treated group and the fluoxetine treated group showed significant difference from the tramadol treated group and the saline treated group in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. 2) Within each drug treatment group, the fluoxetine treated group showed significant difference between before and after the treatment of fluoxetine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. And also, the nalbuphine treated group showed significant difference between before and after the treatment of nalbuphine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. There was no difference between the baseline and after the treatment of nalbuphine in the 5-MeODMT(1.25mg/kg/IP) induced suppression of spontaneous alternation behaviour. We indentified that the opioid kappa agonist that act as dopamine release inhibitor affect the spontaneous alternation behaviour which is an animal model of obsessive-compulsive disorder in rat.

Most of the Korean athletes neglect the elevation of basic physical fitness and so impulsive train for the elevation of record, in the futrue, at the period to eluvate the good record. We can discover the reality not to be the elevation of record because the physical fitness become a problem. This study is the treatment of training for the condition of a physique and a physical fitness of (middle) distance runner (aptitude of (middle) distance runner), and the elevation of basic physical strength for this problem improve. 1. The aptitude of (middle) distance runner (1) The body type ① Middle distance runner is good a leptsome type near of acto type and tall and long hind legs. ② Distance runner is good a acto type near of liptsom type and long hind legs, slender wrist, ankle, long toe. (2) Physical fitness ① Middle distance runner is in favor of the runner who has a superior physical fitness of the ability of endurance, relaxation, rhythm and speed. ② Distance runner is in favor of the runner who has a superior physical fitness of cardiovascular endurance, relaxation rhythm and muscular endurance and the ability of speed and softness are important. 2. Training for the basic physical fitness (1) Power training Put in practice training of a explosive action of jumping, skipping, bounding. (2) Muscular endurance training.

Knowledge acquisition is regarded as the bottleneck in building knowledge-based systems like expert systems. Accordingly, the optimism of future symbolic A.I. has diminished and sub-symbolic approaches have attracted more attention than before in the last decade. Recently, in the database community, data mining has emerged as a hot issue in that it would enable us overcome the difficulty of handling intractably many data. This paper shows a new approach for extracting knowledge in the form of rules, which can be readily applicable to expert systems. Logic minimization techniques are applied to obtain initial rules, and those rules are sorted, reduced, and expanded using condition removal techniques. Additionally, initial data are divided into some number of data sets, and the separately generated rules, after optional processing, are merged and reprocessed to generate final rules. The methods presented her are implemented and tested for noisy input data to prove their validity.
