This study aims to analyze the income structure, cost structure, and profit structure based on data related to the business performance of the boat seine fishery from 1990 to 2020, and to identify the direct and indirect factors affecting fishery profitability through panel regression analysis. The main analysis results are as follows. First, it was found that fish catch has a significant amount of impact on fishery profitability, which is a key factor in improving the profitability of anchovy boat seine fishery. Second, it is necessary to develop carbon-reduced fishing gear, develop fleet-reduced fishing gear, and improve the operating system in order to increase fishery profitability for the short run. Third, it is necessary to create and maintain sustainable profitability for the long run, the continuous fishing vessels buyback program, an active responses to climate change, and the follow-up investigations about marine aggregate extraction in the south sea EEZ are needed.

This study investigated whether there is a correlation between the occurrence of hazardous substances such as vibrio, norovirus, radioactivity, shellfish posion, hepatitis A, etc. and media reports, and whether the occurrence of hazardous substances and media reports affect the production, distribution and consumption of aquatic products. The main research results are as follows. First, it can be seen that there is a difference in the relationship between the occurrence of hazardous substances and media reports according to hazardous substances. Second, it suggests seen that the occurrence of hazardous substances and media reports can have a negative effect on the production and the prices of aquatic products. Third, it was found that the occurrence and reporting of hazardous substances had different effects on the distribution margin of aquatic products due to the complexity and rigidity of the distribution structure. Fourth, consumers feel a threat to aquatic products safety and significantly reduce consumption when hazardous substances occur. There is a possibility that concerns about one item may lead to a decrease in consumption of domestic and imported aquatic products that are not related at all to the occurrence of hazardous substances. In conclusion, aquatic products are exposed to various hazardous substances such as vibrio, norovirus, radioactivity, shellfish posion, and hepatitis A. It was found that the occurrence of hazardous substances and its media reports could cause damage to the fishery sector.

This study is aimed to evaluate the technology levels of shellfish farming in southern coast of Korea and status analysis on research of shellfish aquaculture. With achieving these objectives, it will be possible to present the direction of shellfish farming research and related project. Five major breed of shellfish aquaculture that would be adaptive and sustainable were proposed through consultation and agreement with professional group with more than 15 years of working experience. Moreover also evaluated that levels of technology, industry and market are also evaluated. The evaluation result of the expert group showed that the shellfish farming level occupied the third place in comparison with the US, Japan, Europe, and China. It is estimated that about 13~14 years will reach the level of the highest on average. In addition, most countries are expected to grow by about 10% on average over the next five years. Based on the result of the analysis of 670 research projects (2008~2017), there was little research on climate change and shellfish aquaculture. Besides some of shellfish have not been studied since 2008 and 2013, so it can be mentioned as a future task to be overcome.

Offshore trap fishery managers have payed in advance to attract excellent fishing crew in the minium grantee lay system. This practice can intensify competition among fishery management bodies and increase the burden of fishery manager about income tax and four social insurance programs. The purpose of this study is to identify the problems of advance payment practice in terms of fishery manager in offshore trap fishery. The main results of this study are as follows. First, under the TYPE 1 model, which is the current wage payment manner, there is a risk that fishery manager will not able to return the prepayment paid in advance when the income of fishery management bodies decrease. Second, the TYPE 2 or the TYPE 3 model which reduces or abolishes advance payment can alleviate the burden of fishery manager relative to the deduction of redemption amount, incentive to induce artificial expenses, income tax and four social insurance programs. In conclusion, advance payment practice in offshore trap fishery is placing a heavy burden on the fishery manager. In order to solve these problems in the future, we need to find solutions through similar case studies.

이 연구에서는 부모교육 프로그램 이수 정도와 현재 참여 여부에 따라 부모효능감과 양육스트레스에 차이가 있는지, 부모교육 프로그램 참여 후 부모효능감이 양육스트레스에 어떤 영향을 미치는지를 검증하였다. 이를 위해 서울과 경기 지역에서 한국지역사회교육협의회(KACE)의 부모교육 프로그램을 이수하고 있거나 이수했던 경험이 있는 초등학교와 중학교 학부모 411명을 대상으로 하여, 현재 부모교육프로그램에 참여하고 있는 학부모들은 교육현장에서, 부모교육 참여에 공백 기간을 갖고 있는 학부모들은 방문과 이메일로 설문조사를 진행하였다. 연구결과는 첫째, 일회성 특강 이수 그룹과 정규 프로그램 이수 그룹의 부모효능감에는 차이가 없었으나 양육스트레스에는 차이가 있는 것으로 나타났다. 둘째, 부모교육 프로그램에 지속적으로 참여하고 있는 부모와 공백 기간에 있는 부모 사이에는 부모효능감과 양육스트레스에 차이가 있는 것으로 나타났다. 특히, 부모교육 프로그램 이수 후 6개월이 지나면 부모효능감은 낮아지고 양육스트레스는 1년 이상이 지나면 높아졌다. 셋째, 부모교육 프로그램 이수 후 부모효능감이 양육스트레스에 영향을 미치고 있음을 알 수 있었다. 이러한 결과를 통해, 부모교육 프로그램은 부모효능감과 양육스트레스에 영향을 미치며, 부모교육 프로그램에 지속적으로 참여하는 것이 효과적임을 알 수 있다.
