Because of the radical changes in the domestic and foreign economic circumstances Koreaa fisheries is confronted with difficulties. Along the end of the UR marine products of other nations are rushing into Korea. Also migration of labor to other industries and rise of wage level in Korean fisheries deteriorate managerial conditions. But in Korea which has little natural resourses fisheries is still more important. That is \circled1 creating job opportunites \circled2 increase of income \circled3 supply of foodstuffs and animal protein \circled4 acquisition of foreign currency \circled5 enlargement of domestic market for industrial products \circled6 development of other interrelated industries \circled7 rational use of domestic resourses \circled8 diversification of population and production activites \circled9 contribution to balanced growth of national economy by the developing regional economy. These roles of fisheries in national economy mentioned above are to be excuted forward. In spite of the radical change in the economic circumstances at the end of the UR fisheries if crucial in Korea as a industry. For this our fisheries is to be made to compete with foreign fisheries. Through the cheap price and high quality our fisheries must be came to compete with foreign fisheries and meet the people's needs for marine products. For this it is necessary to maintain high productivity and competitive power. Now with the exception of a portion of the deep - sea fishing, our fisheries is generally paltry, Especially inshore fishery which is the main stock in our fisheries is very paltry and so productivity and competetive power are very low. So to develop our fisheries which has s comparative disadvantage active polices that follows below are to be promoted on a large scale. \circled1 improvement of structure \circled2 augmentation of productivity in fishing ground by making fisheries resourses \circled3 enlargement of finantial and monetary assistance \circled4 effective administration of fisheries cooperative union \circled5 activation of R&D etc These polices which need to be scientific and comprehensive are very valuable. Especially without making fishieries resources we cannot expect economy of scale, promotion of productivity and development of fisheries. And we do also endeavour to gather the results of the study and investigation about fisheries domestic and foreign and do ceaselessly put these to practical use systimatically.

As the activities of global enterprises have become more globalized and the labor movement among nations has increased, many studies have been carried out on the effective adjustment of expatriate managers. By examining the literature over the past 30 years on the adjustment of expatriate managers, this study identified major research trends and presented future research directions. While prior studies have often been cumbersome, time-consuming, and dependent on the researchers' subjective judgments, this study performs a bibliometric analysis using quantitative and visualized reference materials to provide a map showing the evolution process of existing research on the adjustment of expatriates. Using the CiteSpace program, this study conducted a bibliometric analysis of 517 papers focusing on major research trends, research countries, research institutions, authors, and journals. Study results found that the study of international adjustment was mainly focused on self-directed senders, attribution adaptations, and personal characteristics. The United States, Britain, and Australia were the most represented countries, while the most influential institutions included Aarhus University, the University of Wisconsin, and Hong Kong Baptist University. As one of the leading researchers, Selmer of Orhuss University published 19 papers, followed by Luring of Orhuss University. The Journal of International Business Studies (JIBs) most frequently featured studies of overseas expatriate adjustment.

This study aims to determine problems of the damage investigation system of aquaculture products resulting from natural disaster and to deduce improvement plans for such problems. The main problems revealed from this study were as follows: 1) detailed damage investigation is carried out only by one particular organization, 2) for aquaculture insurance subscribers another detailed damage investigation is conducted to reveal the causes of natural disaster by a joint investigator team formed according to a different legislation with a different purpose, 3) damage investigation is usually suffered from lack of labor, budget and time due to the restriction of natural damage to a certain period of season leading to the absence of quick reaction capability for irresistible natural disasters, and 4) there are no specified procedures and protocols for deciphering causes of a natural demage. The improvement plans to find solutions for such problems are as follows: 1) for the investigation, the object, method and role of the investigation organization should be clarified by improving the present legislation, 2) investigation methods for determining the demage causes should be systematized by making a manual to minimize disputes, and 3) supports for the investigation organization should be institutionalized to guarantee sufficient budget and manpower. Under the present circumstance with continuous natural damages, smooth procedures of damage compensation would lead to the management stability of aquaculture farms.

Recently, many studies are being conducted to extract emotion from text and verify its information power in the field of finance, along with the recent development of big data analysis technology. A number of prior studies use pre-defined sentiment dictionaries or machine learning methods to extract sentiment from the financial documents. However, both methods have the disadvantage of being labor-intensive and subjective because it requires a manual sentiment learning process. In this study, we developed a financial sentiment dictionary that automatically extracts sentiment from the body text of analyst reports by using modified Bayes rule and verified the performance of the model through a binary classification model which predicts actual stock price movements. As a result of the prediction, it was found that the proposed financial dictionary from this research has about 4% better predictive power for actual stock price movements than the representative Loughran and McDonald's (2011) financial dictionary. The sentiment extraction method proposed in this study enables efficient and objective judgment because it automatically learns the sentiment of words using both the change in target price and the cumulative abnormal returns. In addition, the dictionary can be easily updated by re-calculating conditional probabilities. The results of this study are expected to be readily expandable and applicable not only to analyst reports, but also to financial field texts such as performance reports, IR reports, press articles, and social media.

The objective of this study was to compare the farm efficiency of members of cooperative firms with that of non-members in Korea. Data were collected from 27 farms members of three cooperatives and 13 non-member farms, based on the managerial achievements of 1999. For the analysis, the data were divided into three different farming types: type I and II of member farms and non-member farms. Economic analysis were implemented using DEA(Data Envelopment Analysis). Major findings was as follows. Total average technology efficiency was 0.782, which implies that there still remains 21.8% of improvement possibility. Among the three types, type I showed the highest technology efficiency of 0.9055, while type II and non-member farms showed 0.7670 and 0.7171, respectively. This means that these farms have relatively high potential improved. Also, comparing technology efficiency by dividing into pure technology and scale efficiency, all type of the farms exhibit a higher pure technology efficiency compared to scale efficiency. Therefore, to improve current technology efficiency, farms need to focus more on pure technology efficiency improvement. Meanwhile, profit analysis based on farm size indicate that most of the farms demonstrated the increasing-return-to-scale, which means it is necessary to extend the farm size to improve technical efficiency. Type I member farms achieve higher profit and efficiency than other two types and relatively higher producer prices through introducing cooperative sorting, grading and packing. Also, these labor saving technologies increased farm size.

A manipulator for test-cup attachment modules, which was a part of a robot milking system, was developed to reduce cost and labor for cow milking processing. A Cartesian coordinate manipulator was designed for the milking process, because it was quite flexible and can be constructed more economically than any other configuration. The manipulator was made use of DC motors, screws for power transmission, a RS422 interface system for the transmission of coordinate values and a one-chip microprocessor, 89C52. Performance tests of the manipulator were conducted to measure experimentally the precision of all axes. Some of the results are as follows. 1. The Cartesian coordinate manipulator was designed and built. Dimension of the three perpendicular axes (X, Y, and Z) and one arm’s axis(W) to pick up and transfer the modules were 700㎜$\times$450㎜$\times$550㎜$\times$650㎜. The arm’s axis moved the teat-cup attachment module, which attached four teat-cup to four teats, detached four teat-cup from four teats, was designed and manufactured by using CAD, CAM and CNC. 3. After 10 replications of exercising the manipulator, mean precision values(positioning error) of X, Y, Z axes wee 0.48㎜, 0.20㎜, 0.19㎜, respectively. Therefore, we conclude the axes to have a precision better than 0.5㎜, had no problem to operate correctly the milking manipulator.

본 연구는 이명박 박근혜 정부 9년 동안 한국 복지체체의 변화를 '확장성의 제약'과 '역진적 성별성'의 강화라는 두 가지 성격을 중심으로 분석했다. 이를 통해 본 연구는 보수정부 9년 동안 복지가 확대된 것은 분명하지만, 이러한 확장이 미래의 복지지출을 축소시키는 '확장성의 제약'이 실현되는 과정이었다고 평가했다. 또한 자유주의 정부 10년에 이어 사회보험 중심의 공적 복지가 확대되면서 한국 복지체제의 역진적 선별성이 공사적 영역에서 강화되었다. 물론 사회보험을 확대한다는 것 자체가 한국복지체제의 역진적 선별성을 강화하는 것은 아니다. 하지만 수출주도형 성장체제가 만들어놓은 산업구조는 노동시장의 분절화를 심화시켰고, 이러한 조건에서 정규직 노동자를 기준으로 설계된 사회보험을 확대하는 것은 사회보장제도의 역진적 선별성을 강화할 수밖에 없었다. 보수정부 9년 동안 한국복지체제의 역진적 선별성이 강화된 것은 바로 이러한 이유에서였다. 결국 보수정부 시기 한국복지체제는 서로 다른 삶을 살아가는 세 집단으로 나누어졌고, 세 집단 간의 불평등은 더욱 심화되었다.

현재 문재인정부의 노동개혁정책은 지난 시기의 국가주도 노동개혁정치와는 구조적 조건이 크게 다르다. 특히 신자유주의 20년에 대항하는 촛불혁명의 연장이자 그 결산이라는 점에서 중요한 차별성을 갖는다. 이런 조건의 변화는 새로운 노동체제출발일 수도 있다는 긍정적 전망을 가능케 한다. 그렇지만 향후 노동개혁의 성패가 매우 불확실한 상황인 것도 사실이다. 그것은 자유주의 보수국가의 개혁이자 보수우위의 정치적 이데올로기적 지형이라는 구조적 요인에 기인한다. 또 경기변동의 불안정성과 항상적인 고용불안 등과 같은 상황적 요인이 맞물려 있기 때문이다. 이런 불확실성을 최대한 줄이기 위해서는 주체의 전략적 실천이 매우 중요하다. 현재의 상황이 노동체제 전환의 과도기일 수도 있으므로 민주노조운동 주체실천의 중요성은 더 크다고 할 수 있다.

This study analyzed the employment efficiency of Korean colleges and universities using DEA(2015 GOMS), which was surveyed by the Ministry of Employment and Labor and the Korea Employment Information Service. The input variables were employment program participants, language educators, family economic applicants, and employment targets. As a result, the college was more efficient than the college and the college was relatively ineffective. The contribution of input and output contributed the highest efficiency with 99.9% of the participants in the employment program, and the possibility of improving the efficiency of the language educator was the highest at 70.04. Based on the results of the above research, it suggests the necessity of activation of employment programs and activation of language training in each university. Future studies will need to study the efficiency of universities nationwide.
