Fishing vessels have been causing more than 70% of marine casualty in Korea. As a view of the occurring number of marine casualty, it is obvious for fishing vessel to account for the absolute high portion of that in comparison with the non-fishing vessels. That is a natural outcome because fishing vessels have occupied more than 90% of all registered Korean vessels. If we consider it not occurring number, but occurring ratio, we could find out that fishing vessels accounted for 5 times lower than non-fishing vessels in marine casualties. Nevertheless, fishing vessels have not immunity from responsibility for marine casualties at all, because the tendency of it in fishing vessel has been dominating the whole marine casualties in Korea. So for reduction of them, it is indispensable to decrease the casualties of fishing vessel. In this study, the authors tried to carry out many items of them to compare the occurring number with the occurring ratio, and dealt with the casualties of collision and machine damage in detail, because those have not only been occurring most frequently in casualties in Korea, but also led to the death and injury of lives. To reduce the collision and the machine damage, the operator have to keep the watch more strictly and check and keep the machine in good order. And it is necessary for the operator to take more education and training intended to decrease those systematically and continuously, especially for the crews of fishing vessels.

The most frequent occurring and the serious marine casualties in fishing vessels are the collision in statistics from Korea Maritime Safety Tribunal (2008-2015). Collisions are is given a great deal of weight in all marine casualties, and the main cause of collisions is the negligence of watching. From this point of view, this study deals with the collision and its immediate cause, the negligence of watching which are main factors on the indirect causes. Basic analyzing data was gathered from the questionnaire made by experts of sea service part, and analyzed by using the fault tree analysis (FTA). From the result of the study, the occurrent probability of the negligence of watching in the collision due to the indirect causes occupied 64.9%, and its probability caused by the man factors was less than the other factors; i.e. the media factors and the management factors. For the reduction of the negligence of watching in the collision from this study, it needs an effort to remove not only the man factors, but also the media factors and management factors.

The purpose of this study is to explore the ecosystem service and benefit indicators of natural seaweed beds. Ecosystems of natural seaweed beds provide a wide range of services and benefits to human society including provisioning services, regulating services, supporting services, and cultural services. Indicators for each of the ecosystem services are chosen by marine plants ecologists and as follows. Ecosystem indicators of natural seaweed beds for provisioning services are well-being food(amount of seaweed harvested/amount of fish landed, fish biomass, area of natural seaweed beds, the number of species, contribution to the second production), raw materials(amount of biomass by breed, amount of aquaculture feed), genetic resources(amount of genetic material extracted, amount of genetic material contained by age and habitat), and medicinal resources(amount of medicinal material extracted). Ecosystem indicators of natural seaweed beds for regulating services are air purification(amount of fine dust/NOx or $SO_2$ captured), climate regulation(amount of $CO_2$ sequestered), waste treatment(amount of N, P stored, biochemical degradation capacity COD), and costal erosion prevention(length and change of natural coast line, amount of sediment prevented). Ecosystem indicators of natural seaweed beds for supporting services are lifecycle and maintenance(primary production, contribution to the second production) and gene pool protection(amount of compositional factors in ecosystem, introduced species). Ecosystem indicators of natural seaweed beds for cultural services are recreation and tourism(the number of visits of an area) and information for cognitive development(amount of time spent in education, research and individual learning about ecosystem of natural seaweed beds).

The increase in demand for leisure time by the public and the vitalization of agricultural tourism resulting from the expansion of the five-day work week are expected to greatly contribute to the rural economy, but actual studies analyzing the ripple effect of the agricultural tourism industry are lacking. In order to analyze the economic ripple effect, tourism or agricultural tourism must become an independent sector in the inter-industry relations table's sector classification, but because it is not, the study uses a method of analysis which involves creating a satellite account. However, because agricultural tourism has a clear main agent in farms unlike general tourism which does not, there is one method in which provisions are made by farms or farm villages and another method in which outside products are used. The purpose of the present is to measure the economic ripple effect of agricultural tourism with a focus on 162 subclasses by applying positive data from the education sector input into agricultural tourism. Satellite accounts which considered intermediate input were created and applied to positive data, the analysis of which revealed agricultural tourism to account for 462 billion won, which is 0.01% of the total production amount of 3,503,480 billion won, while the production inducement coefficient was 3.2895 units when the final demand of agricultural tourism occurs. When the production inducement coefficient is at 3.2895 units, highest sector was agricultural tourism at 0.9968 units followed by restaurants and bars at 0.3325 units, roadt transportation services at 0.3183 units, lodging services at 0.1520 units, and petroleum products at 0.1290 units.

Objective : The purpose of this study was to verify the differences of expressed character strengths graded as per the Korean Strength Scale, based on the type of work. Methods : A total of 2,444 conglomerate workers were classified into two groups: 1,356 office workers and 1,088 production workers. The subjects were examined through a web or mobile application based on the Korean Strength Scale. The Korean Strength Scale consists of a total of four top entries and 25 sub-items with appropriate validity. Results : The difference in the average score of sum of character strengths between the two groups was not significant. In the office worker group, character strengths such as love of learning, creativity, perspective, curiosity, facilitation, judgment and faith had significantly high scores. On the other hands, modesty, hope, gratitude, sincerity, magnanimity and self-regulation were high in the production worker group. The results remained unchanged in additional analysis of covariants as sex, age and education level, except for self-regulation and faith. Conclusion : Our results suggest significant differences in the character strengths between the two types of work; however, the average of sum of character strength score remains unchanged. These results may help to understand differences between work environments and thus help to establish a positive foundation.

효소생산을 최적화하기 위해서 Paenibacillus sp. DG-22에서의 ${\beta}-xylosidase$ 생합성 조절을 연구하였다. Paenibacillus sp. DG-22의 ${\beta}-xylosidase$는 배양액에 존재하는 탄소원에 의해 조절되는 것으로 관찰되었다. ${\beta}-Xylosidase$의 합성은 xylan과 methyl ${\beta}-D-xylopyranoside$ (${\beta}MeXyl$)에 의해 유도되었으나 쉽게 대사되는 단당류에 의해서는 약간 억제되었다. ${\beta}MeXyl$가 ${\beta}-xylosidase$의 유도를 위한 최적의 기질임을 확인하였고 가장 효과적인 유도는 10 mg/ml의 농도에서 얻어졌다. ${\beta}-Xylosidase$의 생산은 세포의 생장과 연관된 양상을 나타내었으며, 대수기 말에 최대양이 형성되었다. Glucose와 xylose가 존재하면 ${\beta}-xylosidase$의 활성 수준이 감소하는 것으로 보아 이 효소의 생합성은 catabolite repression을 받는것으로 보인다. SDS-PAGE와 활성염색 기술을 이용하여 ${\beta}Mexyl$가 이 효소의 생합성을 유도하며 약 80 kDa 크기의 하나의 ${\beta}-xylosidase$가 존재함을 알 수 있었다.

In the present day context of changing information needs of the farmers and diversified production systems there is an urgent need to look for the effective extension support system for the small and marginal farmers in the developing countries like India. The rapid developments in the collection and analysis of field data by using the spatial technologies like GPS&GIS were made available for the extension functionaries and clientele for the diversified information needs. This article describes the GIS and GPS based decision support system in precision agriculture for the resource poor farmers. Precision farming techniques are employed to increase yield, reduce production costs, and minimize negative impacts to the environment. The parameters those can affect the crop yields, anomalous factors and variations in management practices can be evaluated through this GPS and GIS based applications. The spatial visualisation capabilities of GIS technology interfaced with a relational database provide an effective method for analysing and displaying the impacts of Extension education and outreach projects for small and marginal farmers in precision agriculture. This approach mainly benefits from the emergence and convergence of several technologies, including the Global Positioning System (GPS), geographic information system (GIS), miniaturised computer components, automatic control, in-field and remote sensing, mobile computing, advanced information processing, and telecommunications. The PPP convergence of person (farmer), project (the operational field) and pixel (the digital images related to the field and the crop grown in the field) will better be addressed by this decision support model. So the convergence and emergence of such information will further pave the way for categorisation and grouping of the production systems for the better extension delivery. In a big country like India where the farmers and holdings are many in number and diversified categorically such grouping is inevitable and also economical. With this premise an attempt has been made to develop a precision farming model suitable for the developing countries like India.

본 연구는 라디오 노인 대상 프로그램의 제작자들이 어떠한 인식을 가지고 노인 대상 프로그램을 제작하는 지를 고찰했다. 이를 위해 현재 노인 대상 라디오 프로그램 제작에 참여하고 있는 PD, 작가, 진행자를 심층 인터뷰했다. 연구결과, 첫째로, 제작자들은 노인대상 프로그램의 청취자들이 충직한 청취자 군을 형성하고 있다고 파악했다. 노인들은 프로그램 내용면에서는 건강, 정보, 노래 부르기를 선호하고, 진행자와 의사사회관계를 형성했다. 둘째, 방송사들은 이윤 획득이나 청취율보다는 공익 구현과 방송사의 이미지 제고를 위해 노인대상 프로그램을 편성했다. 노인 대상 프로그램은 모두 새벽 시간대에 편성되고 있다는 고정관념과는 달리 채널의 성격에 따라 오후 황금시간대 편성이 되기도 했다. 대상 시청자층은 60세 이상 노인에서 40대, 50대로 확대되는 경향이 나타났다. 셋째로 라디오 프로그램의 제작자의 역할에서는 진행자와 작가의 역할이 돋보였다. 진행자는 해당 프로그램을 상징하는 존재로서 청취자를 결집하는 구심점이 되었다. 작가는 장기간 집필하면서 프로그램의 명맥을 있는 역할을 하며 전문 작가 군을 형성하고 있다. 반면 PD는 방송사의 편성 방침에 따라 6개월-1년 단위로 교체되어 프로그램의 운영이나 내용 면에서 새로움과 변화를 가져오는 역할을 하는 것으로 확인되었다.
