MOTIE(Ministry of Trade, Industry & Energy) aims to build a Southwest 2.5GW offshore wind farm. The job will require help from the government, electric operator and manufacturers. The domestic offshore wind farm market will boost global competitiveness up until 2019. This research analyzes the economic impact of the offshore wind farm project. The local acceptance in terms of production, employment and value added are expected to be maximized. According to the quantitative analysis using the extended 2010 input-output table, we calculated that the production inducement impact will reach up to 13.5 trillion won. 11.07 trillion won from the offshore wind farm industry and 2.4 trillion won from others. Furthermore the impact of increase in employment is expected to reach 22,662. 9,883 will be from the wind farm industry and 12,779 from other fields. The impact is expected to be greater especially during the middle of the jobless growth period, Lastly, the value added inducement impact is expected to be 4.24 trillion won. Regarding economic impacts, strategies required for increasing local acceptance are as follows. First, in order to diversify and sophisticate the primary industry into a secondary or tertiary one, we need to develop the nearby wind farm site into a wind farm thema park. Attracting the wind farm production, installing and maintaining/repairing firms and establishing an experience center for K-12 students by providing them an education center for offshore wind energy can be specific means of development. Also, during the operation and after the destruction of facilities, the government should lay out the sub-structure of the wind farm as a sea ranch. Thirdly, the level of local acceptance regarding the community ownership of the offshore wind farm should increase to those of Middelgrunden(Denmark) and Navarra(Spain). Considering the economic condition of Buan, Gochang and the Yeonggwang area, community ownership is one of best solutions for the increment of local tax revenue. At last, considering the supports system of areas adjacent to power plants and ``Partnership management with local community’, the offshore wind farm operator may need to provide assistant policies to nearby communities. The policies should be based on Corporate Social Responsibility(CSR) such as education scholarship projects, local economy cooperative projects, sports/culture projects.

이원필,이상한 慶北大學校 齒科大學 1990 慶北齒大論文集 Vol.7 No.1

The purpose of this experimental study was to examine and compare the histopathological changes when 95% alcohol and normal saline applied to the sciatic nerves of rats perineurally in vivo. For this study, 10 Sprague-Dawley male albino rats were used as the experimental animals and divided equally into 2 groups. The topical application of 95% alcohol on the right sciatic nerve of rats for 1st and 4th weeks were used in experimental groups Ⅰ & Ⅱ. Physiological saline one the opposite side was the control in groups Ⅰ & Ⅱ. The animals were sacrified on the 1st and 4th weeks after experiments and all specimens were fixed in 10% neutral formalin and 1% osmic acid solution later, embedded in paraffin wax and cross-sectioned with 4-6㎛. After these procedures, specimens were observed under the light microscope. The results obtained were as follows : 1. Control sciatic nerves of rats showed no marked pathological changes with the application Gelfoam saturated with physiologic saline, but the degenerative changes in the partial nerve fibers adjacent under perineurium were observed. 2. In the 1st weeks experimental group Ⅰ, the myelin sheath changes characterized by disintegration, fragmentation, swelling and collapse. The histopathological changes of axons characterized by either swelling, shrinkage or irregular extension, and observed partially axonolysis. 3. In the 4th weeks experiment group Ⅱ, the inflammatory changes were largely subsided and the swelling of the myelin was resolved. The myelin sheath of th partially surviving fibers in the outmost layer was formed, but comparatively thin. The nerve fibers were comparatively sparse, indicating destruction and disappearance of the intervening fibers, and the arrangements were similar to normal structure. Generally the recovery of peripheral nerve tissue was observed. 4. The marked destructive histopathological changes of nerve fibers were restricted to adjacent area immediately under the perineurium. The perineurium itself was intact and showed no inflammatory or destructive changes. And the histopathological destruction in peripheral nervous tissue of rats appeared nonselective. J.

Objectives : This study was performed to analyze the sociodemographic characteristics of participants in '1998 Korean Depression Screening Day' and to evaluate the results of the screening test. Methods : By using the survey results of 619 volunteers from 8 hospitals, the authors examined the prevalence of depression detected at the screening test and sociodemographic characteristics and the psychiatric treatment history of respondents. The assessment measure was the Zung Self-Rating Depression Scale. Results : The mean depression score of all participants was 57.5±13.8 and it came under mild depression. Of all participants, 69.5%(N=430) had at least mild depressive symptoms, 43.1%(N=267) had at least moderate symptoms, and 18.4%(N=114) had severe symptoms. Never have 56.8% of respondents in the severely depressed range and 63.9% of those in the moderately depressed range had psychiatric treatment. The results suggest that the age group of 29-year-old or younger(relative to 60-year-old or older group) and full-time employment status(relative to unemployment) are protective factors of depression. Conclusions : By '1998 Korean Depression Screening Day', many depressed patients were detected and their depressive symptoms had statistically significant relationships with some sociodemographic characteristics. The results suggest that the education and screening test programs for depressive illness facilitated by Depression Screening Day are useful to the patients regardless of being under current treatment or not.

핵비등 영역의 가열면상 물 액적의 증발에 대한 연구

남궁 규완,안강수,원성필 울산대학교 1996 공학연구논문집 Vol.27 No.1

본 연구는 동판, 탄소강판, 스테인레스강판의 가열면상 증류수 액적의 증발시간 및 표면의 온도변화에 대한 것으로 가열면의 초기온도는 핵비등이 존재하는 최저온도로부터 최고 온도 영역의 범위 내에서 논했다. 액적 밑면의 가열면 온도는, Rohsenow가 제시한 푸울 핵비등 열전달 관계식을 사용하여, 2차원 천이 열전도 해석으로부터 계산했으며, 가열면 재질 및 초기 액적크기 등에 따라 합리적인 변화 결과를 얻었다. 또한 본 연구에서 제시한 액적증발 모델은 액적과 가열면간의 접촉면적 변화를 계산하는데 사용되었다. 시간에 의존하는 접촉면 온도와 액적의 기하학적 형상 변화로부터, 특정 액체/고체조합에서 전 증발시간을, 초기 가열면 온도와 초기 액적 크기와 관련하여, 예측했다. This paper discusses the evaporation time of a pure water droplet on smooth surface of copper, carbon steel and stainless steel. The initial surface temperature ranges from the lowest limit to the highest limit of the nucleate boiling region. The surface temperature just below the droplet is calculated from the 2 dimensional transient conduction, using the transfer correlating equation of nucleate pool boiling proposed by Rohsenow. And the evaporation model proposed in this paper is used to calculate the changes of contact area between liquid droplet and heated surface. With these time dependent values of surface temperature and those of geometrical shape of droplet, the total evaporation time for a specific liquid-solid combination can be predicted as the initial surface temperature and the initial droplet size. The predicted evaporation times are compared with the experimental data. Though the present model consists of some assumptions which include bubble waiting time, heat transfer coefficient and the shape of liquid droplet on surface, the predictions and measurements are in good agreement.

신성휴,손명성,김원섭,최승필 한국운동역학회 1998 한국운동역학회지 Vol.8 No.2

This study has been aimed to analyze UCHIMATE technique of Judo gymnastically. The following are the results and the proposition obtained through an image analysis method 3 men half heavy weight champions of the national Judo standing team(85-95kg) were used as subjects for the study. 1. CONCLUSION The following are the conclusion obtained through the discussion of analysis results of the Uchimata technique using 3 men, half heavy weight(85-95kg) champions of the National standing Judo team. 1) The time performing total technique were 1.48-seconds which was performinglonger than the light heavy weight class of 1.28-seconds by 0.20-seconds, this showed that the heavy weight class players demonstrated the technique later than the light heavy weight class palyers. 2) The average length of moving 1-step leg for attacking was 24.27cm, and 2-step leg moving was 92.87cm on average. Therefore, the shorter the moving distance, the more the technique performing hour could be shortened. 3) In the hanging phase, the moving displacement of the center of gravity of the body weight showed in horizontal, vertical, right and left direction 28.97cm, 21.59cm and 13.57cm respectively. Each of which were longer than the phase of KUZUSHI and TSUKURI. Such results show that the center of gravity of the body in move lift the opponent. This reducing the displacement of body weight from the center toward the right and left direction in the phase of KAKE is considered to be effective in demonstrationg the technique. 4)The central speed of the body was 0.8cm per second on average and the average vertical speed was 0.74cm per second. The speed of right and left movement was 0.51cm per second on average which showed the horizontal speed was the fastest while it is preferred that the vertical speed should be faster than that of the horizontal. 5) Angle of the Trunk showed 98.13 ˚ on average in the hanging phase and the larger the trunk angle, the shorter the needed time to demonstrate the technique, thus making the throw of the opponent over shoulder more advantageous. 2. PROPOSTION The following propositions are suggested through this analysis for further study : 1) It is to be considered that the kinetics in hanging the thigh and the degree of every segment of the body be studied in a more detailed fashion. 2) A study on the technique of thigh hanging in an actual game situation (rather than during mere exercises) is necessary. 3) It is necessary to study the TORI and UKE techniques together. 4) The study of each weight class ought to be performed.

Due to increase of population and development of city, people who live in the small country like Korea have great interest in high-rise building. Even though various kind of structure system have been developed and creating. The structure system of the anyone is not applied to all structure system, that's the reason why we have to considerate about the efficiency of economy, structure, energy. Repair high-rise building, horizontal load like wind make more big problem. In order word, resisting against horizontal load almost define the type of structure system. The way setting the high quality structure design is choosing the most economical structure system, In the line with satisfacting the efficiency of construction, technical and standard design format. What I've done from this project contents two point. First thing is comfaring vertical load and horizontal load when I apply shear wall system and tubular system the rectangle floor of 60's and 80's story building. Second thong is comfaring the amount of steel-frame when I setting the size of composite structure. Therefore, We try to present therefore efficient structure system according to an each number of layers.
