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.

본 연구는 2014년 11월 17일부터 2017년 12월 31일까지의 VKOSPI선물을 활용하여 기초자산이 KOSPI200인 포트폴리오의 변동성 위험과 외가격 콜옵션 및 풋옵션의 베가위험에 대한 헤지 포트폴리오 구성시 어느 정도 헤지성과가 있는지를 살펴보았다. 본 연구의 주요 분석결과는 다음과 같다. 첫째, VKOSPI선물의 경우 최근원물거래는 상대적으로 가장 활발한 반면에 원월물 및 원원월물은 거래가 전혀 형성되지 못하고 있었다. 둘째, VKOSPI선물을 활용하여 KOSPI200을 복제 또는 추종하는 포트폴리오의 변동성 위험에 대한 헤지효과를 분석한 결과 최소 24.34%에서 최대 28.51%의 낮은 헤지성과를 보였으며 주가 상승기보다 하락기에 헤지성과가 상대적으로 더 높은 것을 알 수 있었다. 셋째, 외가격 콜옵션 및 풋옵션의 베가위험에 대한 VKOSPI선물의 헤지성과를 살펴본 결과 대부분의 헤지 포트폴리오가 무헤지 포트폴리오보다 포트폴리오 분산을 더 증가시킴을 알 수 있었다. 또한 헤지구간을 무헤지 포트폴리오의 이익발생 및 손실 발생 구간으로 나누어 살펴보면 대부분의 헤지 포트폴리오가 무헤지 포트폴리오보다 이익 및 손실의 변동폭을 더욱 더 확대시킴을 알 수 있었다. 결론적으로 VKOSPI200선물은 선물거래의 비활성화 및 변동성 예측구간의 상이함으로 인하여 KOSPI200지수 및 실현변동성에 대한 설명력이 낮아 기초자산이 KOSPI200인 포트폴리오의 변동성 위험과 외가격 콜옵션 및 풋옵션의 베가위험을 헤지하기 위한 수단으로 미흡함을 알 수 있었다. 이를 해결하기 위해서는 VKOSPI선물시장의 활성화와 변동성 예측구간의 일치가 선행되어야 할 것으로 판단된다. This study focus on the hedge performance about KOSPI200 volatility risk hedge portfolio and OTM Call and Put vega risk hedge portfolio using VKOSPI futures from November 17, 2014 to December 31, 2017. The major empirical results are as follows; First, we analyzed the hedge performance of portfolio that replicates or follows KOSPI200 using VKOSPI futures. VKOSPI futures’ hedge performance was shown minimum 24.34% and maximum 28.51%. We can see that the hedge performance is relatively higher in the period of stock market decline than the stock market rise. Second, we examined the hedge performance of OTM Call and Put vega risk using VKOSPI futures. As a result, Most of hedge portfolio are more risky than the non-hedge portfolio. In conclusion, the VKOSPI futures is insufficient to hedge volatility risk and vega risk due to the insufficient liquidity of VKOSPI futures and the difference in the forecast period of the volatility.

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.

Recently many apartment reconstruction projects have been executed for the improvement of living conditions and the supply of new apartment. But, the process of apartment reconstruction projects contains a lot of risk factor and uncertainty. In addition traditional valuation method, DCF have failed because this method cannot properly capture strategy flexibility and uncertainty of apartment reconstruction projects. So, This study is to suggest the application of the Real Option to apartment reconstruction projects valuation. An Real Option Approach to apartment reconstruction projects has the potential to conceptualize and quantify the value of American Sequential Compound Option by binomial lattice model. We suggest a modeling process of Real Option using Seoul Jamsil OO reconstruction apartment complex. We estimate option volatility by Monte-Carlo Simulation and up step-size, down step-size, risk-neutral provability by Cox, Ross, Rubinstein(1976) method. the main results are as follows. The passive NPV of Seoul Jamsil OO reconstruction apartment complex using DCF method is ￦ 440.4 billion. The value of American Sequential Compound Option by binomial lattice model is ￦ 44.2 billion. So, the expanded NPV is ￦ 484.2 billion when we consider strategy flexibility and uncertainty. Finally we expect that this study will improve the confidency and accuracy of valuation process and more helpful to the decision making about apartment reconstruction project.

The purpose of this study aims to evaluate the economic performance of a freezing and refrigeration factories located in Tongyeong Gyeongnam. We select two cases(A suhyup, B suhyup) to test business feasibility analysis using B/C(Benefit Cost Ratio), IRR(Internal Rate of Return), NPV(Net Present Value) methods. The main results are following. First, the area of Gyeongnam has been ranked 1st on the view of the number of freezing and refrigeration factories, 2th on the view of the capacity of freezing, and 3th on the view of the capacity of refrigeration. Specially, Tongyeong has a relatively more freezing and refrigeration factories than in the other area of Gyeongnam. Second, A suhyup fishery refrigerated warehouse project seems a high economic performance when we consider the effect of supply control. Also the business feasibility exists even though we don't take into account the effect of supply control. Third, B suhyup fishery refrigerated warehouse project economics is present in the best and normal scenario but isn't present in the worst scenario. Forth, the investment funds of cental government and local government influence on the economic evaluation. It can be concluded through the results of this study that the freezing and refrigeration factories located in Tongyeong Gyeongnam have high economic performance by the effect of supply control. However this results calculate under the more relaxed assumptions. So the further study should be conducted under more stringent assumptions.

Tourism is one of the principal economic activities in islands. It is the essential source of job opportunities, livelihood and inclusive growth for such areas. In is paper, we developed and designed a sustainable strategy of tourism industry in Yokjido(island), Tongyeong by focusing on the characteristics of this area. We also suggested the best strategy to enhance tourism industry economically. To accomplish this strategy, we decomposed the tourism concept of Yokjido into two parts, wellbeing and healing. Wellbeing has to do with the natural scenery and environment and also making the tourist`s spiritual and physical mind happy. Healing restores our health from an unbalanced, diseases and damaged organism to a healthy one. Healing involves the repair of living tissue, organs and the biological system as a whole and resumption of normal functioning. The tourism of Yokjido generates all these functions to every tourists. Thus, we should analyze the function of these two types and try to deliver them to all tourist of Yokjido.
