1, The Purpose of Study This is a study on the Evaluation of the operating of Fisheries Extension Services of Korea, for performing the activities such as guiding fisheries technique as well as offering industrial information to the fishermen in fishing village. By doing so, the Fisheries Extension Sevices(FES) can materialize the continued growth of fisheries, the social and economic development of fishing village, and the increase in income by enhancing the knowledge level of Fishermen, etc. In performing fisheries policy, this activity plays a great role on the research and development activity, and it has become practical since 1976 in Korea. In order to meet immediately with the problem of fisheries technical innovation and rapid environmental changes surrounding the fisheries, the fishermen should not only enhance their scientific and comprehensive capacity in fisheries technique but abtain various effective information. Generally, as most of all the fishemen are poor in the managerial structure and scattered in fishing villages, they have little opportunity in the contact of information. As a result, it is nessessary for the FES to perform the fishing business by the extension service officials who has received special training and acquired fisheries know-how in these fields. And yet, FES is under the unfullfilled circumstance in such factors as manpower, technical know-how, equipment, and the service system etc., which is required in promoting the social, economic development of fishing village and in resolving the high technique demand of fisherman. This study on the fisheries extension services have been studied from those backgrounds. 2. Research Method The data of collecting methods which were necessary in carrying out this study was adopted by the questionaire research on the present extension service activity, through the subject of the extension services (driving agency of the work and the officials), the object(fishemen) and the 3rd observers to the extension services (the authorities concerned). The research sample was taken by the sampling extraction of total 1, 774 men from the above 3 groups. And the research was carried out from August, 1986 to October, 1986, supported from the Fisheries Extension Office (FEO) located in field during the research process. In this study, the levels of the extension operating were determined and estimated in accordance with the extension service method, morale of extension service officials and the extension service system, etc. through the collected data of the research questionaire paper. And based on this result, the essential conditions of the extension services were grasped, and also we tried to present the various activity plan necessary to promote the operating of the extension services. The questionaire research data was calculated by the computer center of National Fisheries University of Pusan, and the total result was again tried on the one demension analysis along with two dimension analysis to search out the relativity between the questionaire, and the statistical test was done $\chi$$^2$test in significance level of l~5%. 3. Contents of Study This study consists of 7 chapters and the contents are as follows : Chapter I : The object and method of the study Chapter II : The assessment and analysis of the extension services Chapter III : The contents and method of the extension services Chapter IV : Analysis of the essential conditions for the extension services Chapter V : The evaluation of activities of extension services Chapter Ⅵ : Conclusion.4. Results and RecommendationTherefore, the results of this study estimated by logical process and analysis are as follows : 1) Most of Korean fishing villages and coastal fishermen have shown much concerns about fisheries technique and social changes, thus many of them were confronted with new problems on how to adapt and to meet changes. 2) Majority of fishermen estimated FEO as an organization of specific technologies with all the thing concerning the fisheries technique in general. Therefore the fishermen wanted to utilize the FEO as an adaptable method for the modern fisheries techniques as well as the environmental changes. 3) In contrast with the fast changes of the fisheries technique, the complexity and variety of technical system and the broadness of fishing village and fishermen, it was revealed that the necessary factors such as the facilities, manpower, budget, and the level of applying techniques of the FEO located in field were highly insufficient. Accordingly, the guiding efficiency was low and the extension services did not provide full solution to the various request from fishermen. 4) It is possible to classify the activation factor for the extension service into two large dimension ; personal dimension relevant to guidance officials and work dimension relevant to the organization. And it was found that the activation level of the work dimension was far lower than the personal dimension between them. So, the activation should be done first in the dimesion to promote the activation of the extension services. 5) The extension services officials are now demoralized in general, thus it is necessary to take reality into consideration : the expense of activity, the adequate endowment of activity scope and the reasonable operation of the position class, etc to enhance its morale. However, in order to do the FES activation, first of all, the systems should be established which is lain unsettled stage until now. And there must be change in the understanding of government i.e. the fisheries extension services are the essential policy subject to build up the base of fisheries growth and modernize the fisheries management. And it should be driven positively with the recognition of the "lasting project".g project".uot;.

The character of the educational tradition of Germany could be divided into two aspects. One is the humanistic liberal tendency and the other is vocational. From the beginning of the Twentieth Century, however, there has been an attempt to unify these two trends by the . Georg Kerschensteiner is the first of importance to make some comprehensive curriculum for this goal. In Kerschensteiner, the genuine education makes the individual assume his work and role in society, and to develop them by cultivating insight, will and power. His view is well expressed in the slogn "The vocational education is the beginning of the humanistic education." His goal is to make men of independence and autonomy through vocational education. The theory of Kerschensteiner's education is called 'general vocational education'. The reason why is that his vocational education concerns not just technical training for industry, but also general liberal arts. In this point, Kerschensteiner's point of view goes back to Wilhelm von Humboldt, neo-humanist afar in the first half of the Ninteenth Century, and to John Dewey, pragmatist in the contemporary age of Kerschensteiner. Kerschensteiner was much influenced by Humboldt's concepts of power and individuality. These concepts came to be embodied as a principle of vocational education in Kerschensteiner. Furthermore, Humboldt's concept of power could be associated with Dewey's theory of reflexive thinking. The power in Humboldt is to create spirit, which is connected with the world outside through language. The reflexive thinking of Dewey is a process that examines and selects some alternative thinking in the consciousness before acting. This process makes one find the method of problem-solving which results in behaviour. That is the experimental spirit or pragmatic behaviourism. These theories are reduced to the concept of 'work' in Kerschensteiner. And Kerschensteiner's theory of education that has both sides, humanistic and vocational, is similar to that of John Dewey. Dewey brings forward the idea that the vocational education is the best way to cultivate intelligence and emotion, as intelligence operates best in the life. The position of Dewey is in accord with that of Kerschensteiner who intends to cover experiences of various fields of society through practice-learning, and to have knowledge got from outside of school, refuting the misled trend of education isolated from real life. However, there is some difference between Kerschensteiner and Humbolt or Dewey. While the Neo-humanism of Humbolt and the pragmatic education of Dewey put emphasis rather on the liberal arts and culture of individuality, Kerschensteiner is concerned more with the work and life of the reality of society as a group. Kerschensteiner's concept of utility is related to education for the whole man and to the work of the individual and the nation as well as the will and power to practice it. The ideal man of utility of Kerschensteiner is to learn perfectly the value and behaviour of society through vocational life and to have right view of the state establishing a sound mutual relation between individual and state. Kerschensteiner is regarded as a devotee of 'the state of harmony' or 'the ideal of the state', as he makes the state as the criterion for defining the role of the individual. It can be said that Kerschensteiner is not a democrat of the American style as Dewey is, as he makes much of the value of the nation and state. However, he is a humanist and democrat in the point of vocational education. His purpose of education is to make whole men through work and vocational education.

In December 1990, Occupational Safety and Health Law was amended to reinforce employer's responsibilities on employees' health and safety. Among the amended law it was important to expand the role of an occupational health nurse to the role of an occupational health manager. An occupational health manager should take charge of coordinating periodic health examination and environmental hazard evaluation, providing primary care, monitoring employees' health status, giving the workplace walk-through, selecting safe protection equipment, providing health information, counseling and health education, independently. This position of occupational health nurse is equivalent to the role of doctors or occupational hygienists. In 1991, government made a master plan to prevent occupational disease and injury. Under the plan, Korea Industrial Nursing Association (KINA) was established in 1994 with the purpose of improving health services and upgrading career opportunities for members. Therefore, this study was designed to analyze the transition of occupational health nursing education with the changes of law and policy in Korea between 1991 and 1996. In details, it was to analyze the rate of school providing occupational health nursing practice based lecture, lecture hours, lecture contents in undergraduate curriculum, program contents of graduate school, kinds of continuing education, etc. For this purpose, we conducted survey two times. In February 1991, baseline study was conducted with all nursing programs in Korea (19 BSN programs and 43 nursing departments of junior college). From April to May in 1996, the second survey was conducted with all nursing programs (38 BSN programs and 69 junior colleges). The first response rate was 66.1% and the second was 40.6%. Structured questionnaires were mailed to the deans or the community health nursing faculties. In the case of graduate school, telephone survey was conducted with 10 school of public health or environmental health area. Data from the yearbook of Industrial Safety Training Institute (ISTI), the history of Korea Industrial Health Association, and the journals of KINA were also included in the analysis. As the results, we found that there were remarkable improvement in undergraduate and graduate programs, obligatory as well as voluntary continuing education in terms of occupational health nursing expertise between 1991 and 1996. 1) The number of school providing occupational health nursing practice-based lecture was increased with the rate from 7.3% to 25.6%. The rate of school giving over 15 class-hours was increased from 33.3% to 46.6%. 2) Content areas were composed of introduction of occupational health, occupational epidemiology, industrial hygiene, occupational disease and injury, law and policy, health education, concept of occupational health nursing, role of occupational health nurse, occupational health nursing process, etc. Of content areas, occupational health nursing process was more emphasized with the increased rate from 43.9% to 88.4%. 3) In the case of graduate school, occupational health programs were increased from 4 to 10. One of them has developed occupational health nursing program as an independent course since 1991. 4) The law increased educational hours from 28 hours to 36 hours for introductory course at the time of appointment, and from 14 hours to 24 hours every 2 years for continuing education. Course contents were Occupational safety and health law, introduction of occupational health, health education methodology, planning and evaluation, periodic health exam, occupational disease care, primary care, emergency care, management, industrial environment evaluation, etc. In 1996, Korea Industrial Nursing Association has begun to provide continuing education after Industrial Safety Training Institute. 5) Various educational programs in voluntary base were developed such as monthly seminar, CE articles, annual academic symposium, etc. It was shown that changes of law and policy led rapid growth of occupational health nursing education in various levels. From this trend, it is expected that occupational health nurse expertise be continuously to be enhanced in Korea. Legal and political supports should proceed for the development of occupational health nursing in early stage.

It needs to put into practice the systems analysis in the analysis of some operations and status of library for the purpose of systematizing the work of reforming in the new easier form to process, to storage, to retrieve and to make use of the increasing informations and data of library. In this study, some of systems which are generally using in every library was caught in the case study of K university library. Having analyzed them with the two methods of the flowcharting and mathematical analysis, we found the obstructive factors in operation. As the result of this research, it was gained the new system as the alternative one. A. Alternative System B. Advantages of alternative systems 1. In the reference room When it converts the present system into the new system, it can profit 6.771 won/user (13.815won-7.044won=6.771 won). Therefore, a half the average required cost of the present system can be saved. If this saving would be alloted for the cost 33,000won required to make the cataloging cards, it would be taken for 94 days (33,000 won ${\div}$ 6,771 won/user=4,874users. 4,874users ${\div}$ 52users/day=94days) to get it. The saving cost/year by the new system will be 95,417 won, and in the first year the initial cost (33,000won) reduces the saving cost to 62,417won. 2. In the periodical room The average required time for using the materials of the present system is 17 minutes/user and the average required cost/user is 23.775won, while the average required time of the new system is 4 minutes and the average required cost/user is 5.33won. Therefore, the new system has profit 4 times of the present system. Accordingly, it occurs when the dispersed periodical materials get together. 3. In the classification and cataloging When one processes - the oriental books - by the Linear Programming Technique, the maximum of the process can be increased from 11.6 volumes per librarian of the present system to 12 volumes per librarian of the new system increased 0.4 volume in a day, and cataloging by the manual printer can be shorten from 3 minutes per card of the present system to 1.5 minutes per card of the new system. Consequently, we can complete the other operations (books equipment, updating of cataloging cards, etc.) with 141 minutes which are saved in the course of the afore-mentioned works. 4. In the status of collections The average growth rate of 4 years from 1968 to 1971 is 9.825 %, and that of the purchased materials is 6.2% similar to the advanced nations, but it has the different position from 215,000 volumes by the Standard Degree for Establishment of College and University, and the difference between the total collections 151,671 volumes and Dunns' growth model ($N_t=N_oe^{-at}$) claimed by Leimkuhler 155,297 volumes in 1971 is 3,626 volumes, and for the purpose of compensation the difference, we found the fact that it needs to have the increased budget of 24~30% per year, Thus, if the budget of 24~30 % per year. Thus, if the budget would be increased per year as the rate of the afore-mentioned figure, it would be reached at the Standard Degree for Establishment of College and University in 1975, and thereafter, it can be decreased to the lebel which is able to maintain the growth rate of 5~6% per year.

오늘날 문화콘텐츠 산업은 그 특성상 제조 산업 보다는 서비스 산업에 가까우며, 콘텐츠의 완성도나 품질이 높더라도 소비자의 눈높이에 맞지 않는다면 시장경쟁에서 우위를 차지하기 어렵다는 현실적인 제약을 가지고 있다. 이는 비즈니스 계획이나 활동이 콘텐츠의 완성도나 품질과 적절하게 조화를 이루었을 때라야 시장 내에서의 성공을 기대해 볼 수 있다는 뜻이며, 그만큼 글로벌 환경에서의 비즈니스 경쟁이 중요하다는 의미이기도 하다. 다시 말해, 문화콘텐츠 산업에서 콘텐츠 창작력은 당연히 중요한 것이지만, 앞으로는 유통 프로세스를 구축관리하고 부가가치가 적절하게 배분될 수 있는 시스템을 만드는 것이 보다 더 중요한 역할을 할 것이라는 의미이다. 특히나 애니메이션은 장르의 특성상 다른 콘텐츠에 비해 상대적으로 문화적 장벽의 영향을 덜 받는 장점이 있다. 이른바 문화적 할인율이 영화나 드라마와 같은 여타의 영상 콘텐츠보다 낮다는 뜻이다. 하지만 국내 애니메이션의 경우, 이러한 이점에도 불구하고 영화 산업이나 방송 산업에 비해 아직까지 산업적 인프라가 상대적으로 취약하고, 분야별 전문 인력 또한 매우 부족하여 해외유통에 있어서의 현실적 제약을 해결하기 위한 보다 근본적이며 구체적인 방안이 요구되고 있다. 이와 같은 필요성과 국내 산업이 처한 상황을 종합적으로 고려하였을 때, 가장 효율적으로 운영될 수 있는 방안이 온라인을 통한 국산 애니메이션 콘텐츠의 B2B형 마켓플레이스 구축이다. 이는 기존의 소극적인 방식에서 벗어나 온라인을 통해 보다 효과적이며 광범위한 유통방식을 선택하는 것을 말한다. 이러한 온라인 마켓플레이스가 발굴 정착된다면 국내의 다양한 애니메이션에 대한 정보를 실시간으로 전 세계의 잠재적 고객들과 공유할 수 있게 된다. 또한, 다원적인 유통창구로도 활용되어 추가수익을 창출하고 이를 통해 부가시장이 활성화되어 국산 애니메이션 콘텐츠의 보다 높은 국제적 경쟁력을 확보 할 수 있을 것으로 기대된다. 아울러 국내 애니메이션 콘텐츠산업은 질적, 양적 성장을 이룰 것이며, 기존 콘텐츠 제작자와 유통사업자간의 불공정거래 및 왜곡된 수익배분 등 후진적 유통환경 개선을 통해 선순환구조 확립에 일조하게 되어 궁극적으로는 전 세계시장에서 일정한 가치를 갖는 브랜드 자산을 형성할 수 있다. 또한 동시에 한국 애니메이션의 국제적 브랜드화를 보다 빨리 확립할 수 있는 기회가 될 것이다.

2004년 기준, 온실가스(GHG; Greenhouse Gas) 총 배출량 약 5억9,060만톤(t)$CO_2$로 배출량 세계 10위권인 우리나라는 국제 환경의 변화를 볼 때 향후 반드시 GHG를 감축해야한다. 2004년 국내 에너지 부문 중, 전력 발전 및 산업 부분에서 배출된 이산화탄소(CO$_2$)량은 총 2억9,685만t으로 우리나라 GHG 전체 발생량의 53.3%를 차지하여 이 두 분야에서 CO$_2$ 배출을 감축시키는 것이 가장 시급하고 중요한 문제이다. 또한 이 두 분야는 산업의 특성상 CCS(Carbon Capture and Storage) 기술을 적용하여 효율적으로 CO$_2$를 저감할 수 있는 가장 잠재력이 높은 분야이다. 두 분야에서 효율적으로 적용될 수 있는 CCS 기술로 단기적으로는 amine을 이용한 화합흡수법이, 중, 장기적으로는 ATR(Autothermal reforming), 또는 MSR-H2(Methane steam reformer with hydrogen separation membrane reactor)가 장착된 연소 전 기술과, SOFC+GT(Solid oxide fuel cell-Gas turbine) 같은 순산소 연소 기술이 가장 유리 할 것으로 예상된다. 이와 같은 최신 연소 전 및 순산소 연소 기술을 이용하면 향후 CO$_2$ 포집 비용을 $US 8.5-43.5/tCO$_2$로 줄일 수 있으며 이를 이용하여 전력 발전 및 산업 부분에서 발생하는 CO$_2$의 10%만을 감축하더라도 약 3,000만t의 CO$_2$를 저감할 수 있겠다.

포항 칠인정원림의 건립취지, 조형의도 그리고 변천과정 등을 살펴봄으로써 조선조 누정 조영의 시대적 감각과 조영의장을 조명하고, 원림내 회화나무와 느티나무 식재의 문화변용 현상을 살펴 본 연구의 결과는 다음과 같다. 2주의 괴목(槐木) 식재로 인해 쌍괴정(雙槐亭)이라는 또 다른 이름을 얻은 칠인정(七印亭)은 고려말 관료 출신의 장표(張彪)가 태종9년(1409) 초곡리 사일마을에 건립한 은거형 정자이며, 칠인정원림은 쌍계구곡(雙溪九曲)의 제3곡인 초곡(草谷)의 핵심이기도 하다. 칠인정원림은 사일마을 비보숲 초입의 진입부(進入部)와 칠인정 및 느티나무와 회화나무로 이루어진 정자부(亭子部) 그리고 방지방도(方池方島)의 지당과 배롱나무로 이루어진 지당부(池塘部)로 구분된다. 칠인정 기문 내용이나 아들과 사위 7인의 인수(印綬)를 쌍괴수(雙槐樹)에 내건 것에서 기인된 당호(堂號)로 볼 때, 초건 시 식재한 괴목과 그 이후 보식(補植)한 수종 또한 삼공(三公)의 지위와 학자수(學者樹)를 상징하는 회화나무(홰)로 보는 것이 합당하다. 뿐만 아니라 영조21년(1745) 보식한 수종이 현재 칠인정에 존치하는 느티나무(괴)라고 알려져 있음에도 불구하고 칠인정 담장 밖의 회화나무가 당시 식재한 그 수목임을 배제할 수 없다. 요컨대 느티나무와 함께 칠인정원림에 심겨진 3주의 회화나무는 인동장씨 후손들이 회화나무(홰)와 느티나무(괴)의 차이점을 인식하였음을 알리는 최소한의 징표가 아닐 수 없다. 회화나무가 국내에 들어오면서 한편으로 회화나무로, 다른 한편으로 느티나무로 인식되었고 점차 구입용이성, 성장속도, 장수목으로의 성장가능성에서 회화나무와 비교우위에 있는 느티나무를 회화나무 대용(代用)으로 혼용한 자발적 문화변용 현상을 칠인정원림의 괴목 식재사례를 통해 목도(目睹)하게 된다.

This study is designed to examine feasibility and limitation of outsourcing in cooking Western food in a hotel, to interpret importance of outsourcing(eg. outside order, outside procurement, outside supply) in a broad sense in order to reinforce the core capacity in the cooking department, and to know whether the cooking human power is efficiently used and how much the chefs recognize outsourcing of food materials. As many companies conduct restructuring to cut down its size, the reduction of human power led the Western food cooking in the hotel to lower core capacities, lower quality, and lower efficiency. In addition, the sagging morale of chefs undermined creativity. To change from the traditional kitchen to an economic kitchen needs to look into importance of outsourcing, cognitive attitude of chefs, relation with outside suppliers. Here suggests performance of positive changes in the structure The study examined feasibility and limitation of outsourcing in the hotel kitchen as well as chefs' cognitive attitude toward outsourcing of food materials to reinforce core capabilities of the hotel kitchen. 1. Companies of outsourcing are selected according to variability of price conditions, flexibility of contract conditions, popularity of the outsourcing company, and reputation of the outsourcing company. 2. The importance of outsourcing in the Western food cooking is divided into 4 factors such as standard of selecting outsourcing companies, policies of cooking manu, quality of cooking, and quantity of cooking. 3. The most feasible section in outsourcing of food materials is a process of kneading flour for bread, which shows that many Western-food chefs expect to put higher possibility of outsourcing on the kneading. In other words, when it comes to confectionery and bakery, there are many outside expert processing companies supplying high quality products. In the order of outsourcing feasibility, sauce is followed by processed vegetable, garnish of main dish, and soup. The least feasible section in outsourcing of food materials is appetize. Appetize includes a concept of a improvised dish and needs speed. Due to its color, freshness, and sensibility of taste, the appetize plays a key role in the Western food cooking. 4. When outsourcing is taken in place, the highest risk is to lower the inner cooking skills. Therefore chefs in charge of the Western food sequently recognize both internal problems including storage of cooking skills, unstability of layoffs, and loss of cooperation between departments, and external problems including inferior goods, difficulty of differentiating manu, delay of delivery, and expiration date. It shows that most of the Western food chefs consider risks of the internal problems at first. 5. A effective outsourcing needs appropriate selection of outsourcing companies, maintenance of credibility, active communication, check and management of hygiene. However regardless of their position or career, chefs in charge of the Western food have the same cognitive attitude toward selecting successful outsourcing companies after the outsourcing system is enforced. The core of cooking, or a final stage in the full process of so-called artistic cooking, should be treated with insourcing. Reduction of several cooking processes resulted in shortened cooking time, increased efficiency, faster cooking, cutting the waiting-lines, and finally more room for customers. The outsourcing system can reduce or eliminate the following processes in cooking: buying various food materials, checking, storing, preparing, and processing. Especially in the Western food cooking department of a hotel, the outsourcing system should be enforced to make an economic kitchen and to efficiently manage it. Wow it's time to change from the traditional kitchen to an economic kitchen in the hotel cooking department. For that, the cooking department should become a small but strong organization by outsourcing except its core work.

본 연구의 목적은 4 종류의 저 침습 고정성 국소의치의 수직하중에 대한 저항을 연구하여 임상 활용에 도움을 주기 위함이다. 상악 우측 제 1 대구치 결손을 가정하여 상악 제 2 대구치와 제 2 소구치를 지대치로 하는 고정성 국소의치 금속 다이를 제작하고 4 종류의 저 침습 고정성 국소의치 (Resin bonded FPD, Two Key Bridge, Human Bridge without occlusal rest, Human Bridge with occlusal rest)를 제작하였다. 만능 시험기를 이용하여 수직하중을 가하여 실패 시의 최대 하중을 기록하고 실패 유형을 기록하였다. 평균 최대 하중은 Resin bonded FPD 군이 7,295 N, Two Key Bridge 군이 4,729 N, Human Bridge without occlusal rest 군이 2,190 N, Human Bridge with occlusal rest 군이 3,073 N 이었다. Resin bonded FPD, Two Key Bridge, Human Bridge 군 사이에는 통계학적 유의차가 있었으나 occlusal rest 의 유무에 따른 Human bridge 군 사이에서는 통계학적 유의차가 없었다. 보철물 실패양상은 Resin bonded FPD와 Two Key Bridge는 양측 지대치의 유지부 한쪽이 탈락되는 경우가 양측 모두 탈락되는 경우보다 많았으며 Human Bridge 군은 모두 지대치 양측의 유지부가 함께 탈락되는 경우가 한쪽이 탈락된 경우보다 더 많았다. 본 연구에서 저 침습 고정성 국소의치의 수직 하중에 대한 저항은 Human Bridge 군이 resin bonded FPD 군이나 Two key Bridge 군에 비하여 낮은 것으로 나타났다. 따라서 임상에 적용할 때에는 이와 같은 파절 저항을 고려하여 수복 위치의 최대 교합을 참고하는 것은 물론이고 각종 수복물의 탈락에 대한 저항, 그리고 치질의 삭제량, 환자의 협조도 등을 고려하여 각각의 환자에 적합한 수복물을 선택해야 할 것이다.
