This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.

This paper presents the results of research to develop an automatic measurement of a navigation by Global Positioning System(GPS) technique with the help of NavTrac model(manufactured by Trimble Ltd.). An experimental cruising assesses the accuracy of the GPS for the dimensional navigation. The GPS position was analyzed in terms of the plane coordinates(X, Y), which are gained by the transformation of WGS-80 to Tokyo coordinate. From the results of the test cruising, the differences between actual and cruised coordinates are did not exceed ±25m. This error bound is assumed to be an heuristic discriminative region at 1/25,000 base map. The use of this GPS positioning technique would be well suited for avariety of applications where cost effectiveness becomes an important factor.

Background and Objectives : Severe irradiation on the cerebral cortex of the human and animals may result in functional alterations of central nervous system. The purpose of this study, the irradiation effects on the cerebral cortex of the rats after brain irradiation was to investigate the change of distribution and morphology of neuropeptide-Y(NPY) neurons. Materials and Methods : Radiation was produced by the linear accelerator 6MV X-ray, and the animals were categorized into control and experimental groups and we use 45 Sprague-Dawley rats weighing about 200~250gm. The head areas of the animals were positioned within the radiation field of 12㎝ × 20㎝ and with the radiation depth of 1.5㎝. Sodium chloral hydrate-anesthetized rats were exposed to the radiation with the dose rate of 240 cGy/min. The total dose was 1800 cGy. Animals were sacrificed on 2 hours, 5 hours, 1 day, 3 days, 7days after brain irradiation. Under anesthesia, animals were perfused with 4% paraformaldehyde-1% glutaraldehyde solution. On one or two hours after the perfusion, brain were taken out and refixed over night in the same fixative. Using ABC immunohistochemistry, morphology and distribution of neuropeptide-Y immunoractive(NPY-IR) neurons were studied on the cerebral cortex of the control and brain-irradiated rats. We used light, transmission electron and confocal laser scanning microscope. Results : The following results were obtained : 1. On control group, NPY-IR neurons were found in all layers of the primary sensory and motor cerebral cortex, and the NPY-IR neurons were concentrated within the layer II, III, IV, V and VI. The typical NPY-IR perikarya was bipolar and multipolar shape. 2. On 2 hours, 5 hours, 1 day after X-irradiation, decreased number of NPY-IR neurons were detected in the primary sensory and motor cerebral cortex of the rats. Also shrunken and transformed NPY-IR neurons were detected in the primary sensory and motor cerebral cortex of the rats. 3. On 3 days and 7 days after X-irradiation, morphology and distribution of NPY-IR neurons in the primary sensory and motor cerebral cortex was generally restored. 4. In optical serial section analysis of NPY-IR neurons, high fluorescence intensity were observed in a part of the 8~11 sections of the control and all irradiated groups. In optical single section analysis of NPY-IR neurons, red color(high fluorescence intensity) was observed in a part of 6, 7 sections of the control and all irradiated groups. 5. By electron microscopy, NPY-IR neurons on 2 hours, 5 hours, 1 day after X-irradiation rats exhibited severe alterations of their organelles concerning intracellular material transport ; such as disappearance of microvilli and basal infoldings, reduction of invaginating pits on the basal and apical plasma membranes, reduction of transformed vesicles and shrunken Golgi complexes, etc. Conclusion : From the above results, it was concluded that the release of neurotransmitters and transcapillary leakage of blood substance were occurred on 2 hours, 5 hours, 1 day after X-irradiation, but the condition was generally restored on 3 days and 7 days following X-irradiation.

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school
