Shrimp beam trawl fishery is one of the important coastal fisheries in Korea. It has a regulation to the length of beam (8m) and wing net (7m) of shrimp beam trawl that has been used in the district of Junlanam-do and Gyungsangnam-do. This regulation was made in relation to the size of shrimp beam trawler of 3-ton class at that time. Now the shrimp beam fishing vessel has a limit not greater than 5 tons in gross ton. Recently, with improvement of fishing industry and fishing vessel fishermen asked the expansion of the length of beam and wing net, therefore it is necessary to investigate the effect of lengthening the beam and wing net length. Three different beams (8m, 10m and 12m in length) and three different wing net (7m, 10m and 13m in length) were made and the experiment was conducted near Narodo of Goheng by two fishing vessels of 4.98 and 4.88 tons in gross ton between June 2011 and October 2012. When the length of wing net was increased from 7m to 10m and 13m, the relative catch ratio in total biomass was increased 25% and 79% for shrimp, (17% and 22% in total), respectively. And when the beam length was increased from 8m to 10m and 12m, the relative catch ratio was increased 35% and 84% for shrimp, (21% and 37% in total), respectively. The force exerted to the iron guide of inhauler’s with the beam length of 8m was about 30% greater than that with the beam length of 10m when hauling the shrimp beam trawl net.

This study show in the Social Work Field(focus on the welfare facilities) about Literature and Concept Definition on the 'Welfare Management' and 'Efficiency'. And, show a case to study for 'Management' and 'Efficiency' on the 'welfare facilities'. Also, this study try to find on the development of the Social Work Field through the 'Welfare Management' and 'Efficiency'. First, show the new concept on the 'Welfare Management'. Existing 'Welfare' and 'Management' have been using independently of each other in their field. but now, when use the 'Welfare Management' that a new word, define the word 'Welfare Management' and help to another researcher who study on the 'Welfare Management'. Second, show the exemplary case on the 'Welfare Management' and 'Efficiency' in welfare facilities. It arrange for exemplary and typical case in the various study case and basic information offer to the persons who try to study for 'Management' and 'Efficiency' in social work field. third, In the Social Work Fied, I try to find a way to vitalize and development that the study and practice on the 'Welfare Management' and 'Efficiency'. Exisiting 'Management' & 'Economy' treat the terms unprofessionally in the Social Work Field. Social Work Field must cope with quickly and correctly to the current of times like that unlimited competition & development, downfall of the traditional social safety net, economic crisis of a welfare state, etc., in immense framwork of a capitalistic society & a new liberalism. And changing paradigm of social welfare policy. In the end, this study try to find a way for more growth of the Social Work Field trough the 'Welfare Management' and 'Efficiency'. Keywords : Social Work Field(Social Welfare Facilities), Welfare Management, Efficiency

Recently, the various information according to the company management is originated in the change of the rapid company environment. And the necessity of the administration,that is systematic and efficient toward the various document of a form, is gradually increased. At the same time, the efficient management ability of the various standard document obtained the specialized quality authentication system including the ISO/TS16949, ISO14001, quality 5 star, and etc., it maintains occupies the very important part as to the company management. This research suggests the standard business process of the auto part supplier for the efficient management of the standard document. In addition, by building and managing the standard management system will be able to expect the more efficient document management and the product reliability insurance.

  The objective of this research is to select the most effective technique among task related techniques(motion & time study, job redesign, physical environment improvement) for improving work efficiency in shipbuilding enterprise. This study consists of

Purpose - Due to the lack of physical activities and the increase of sedentary behaviors such as screen time, the health condition for contemporaries has been deteriorating. This study is designed to investigate how the use of worktable or tools unfit for body and sedentary behaviors can exercise influence on muscular skeletal disease and how it has an impact on lowering work efficiency and the quality of life with the medium of the muscular skeletal disease. Research design, data, and methodology - The research has developed a questionnaire with 5 hypothesis. The questionnaires were also made by interview and E-mail. 350 copies of questionnaires were distributed and 315 questionnaire were used for the analysis as valid data responses. SPSS ver.22.0 were used and made Cronbach's and reliability test, correlation, Baron & α Kenny 3 step mediated regression analysis. Results - The research has found that living environment factors have positive effect on the occurrence of musculosketal disease. Particularly, repeated use of unfit worktable or tools has a positive effect on the muscular skeletal disorder. And sedentary lifestyle also has a positive effect on the disease. The musculoskeletal disease caused by living environment has a positive impact on lowering the work efficiency. This study has also showed that the muscular skeletal disease has mediated the relationship between the living environment factors and the decrease of work efficiency due to musculoskeletal disease. The musculoskeletal disorders can effect the decrease of the quality of life as well, for the decrease of work efficiency has a positive effect on lowering the quality of life. Conclusions - Sedentary lifestyles, the use of worktable unfit for body, and the repeated use of a tool have caused the increase of muscular-skeletal diseases, and reduction of productivity as well as the hight cost of medical treatment for our contemporaries. Understanding the cause of disease morbidity, finding ways to prevent the disease, and educating people about them would contribute not only to improvement of individual health but also to the advancement of welfare for all.

본 연구는 무인항공기를 활용한 원격탐사적 기법을 통해 고해상도 정사영상과 수치표고모델기 반 3차원 지표모델을 구축하여, 광해복구사업의 중간단계 모니터링에 활용하고 그 효율성을 고찰하였 다. 무인항공기를 통한 원격탐사로 3.8 cm의 공간해상도를 갖는 수치표고모델 및 정사영상을 구축하 였으며, 광해복구사업의 중간과정을 모니터링하였다. 또한 고해상도 영상을 통해 사물 및 지형적 구분 이 용이함을 확인하였다. 구축된 수치표고모델을 기반으로 3차원 모델을 구축하였고 토양복구사업의 면적 및 체적 등의 공간정보를 추출하였다. 그 결과 사업 결과모델 형성을 위한 추가적인 토양 적치 총량은 268,672 m3이며 약 71만 톤의 양에 해당하는 것을 확인하였다. 이는 무인항공기의 광해복구사 업 모니터링의 효율성을 증명하는 것으로 추후 보다 많은 활용도를 보일 것으로 사료된다.

전자해도 시스템은 2012년 7월 1일 부로 국제항해에 종사하는 선박에 단계별로 설치가 강제화 되었다. 전자해도시스템은 백업장치 를 비치할 경우 종이해도를 대체하여 사용할 수 있는 설비로 선교에서 사용의존도가 높은 핵심항해설비라고 할 수 있다. 현재 전 세계적으로 전자해도 시스템 이용 시 다양한 오류가 발생하고 있으며, 국제해사기구 및 국제수로기구에서도 문제를 인식하고 오류해결을 위한 방안을 모색 하고 있는 중이다. 본 논문에서는 선장 항해사를 포함하는 사용자들을 대상으로 전자해도시스템의 이용 시 오류 발생현황과 정보표시 및 주요 기능 이용 시 개선 요구사항에 관한 설문을 시행하였다. 그 결과를 기반으로 항해안전과 효율측면에서의 ECDIS 기능 개선사항을 제시하였다. 조사에서 사용자들은 ECDIS 기능사용에 있어 대부분 효율성 측면에서는 긍정적으로 평가하였으나 항해안전성에 대한 불안감을 많이 느끼는 것으로 나타났다.
