Developing an efficient remanufacturing process that mitigates severe failure in particulate metal catalysts (PMCs) is necessary to reduce environmental pollution (e.g., CO₂ emission) and manufacturing costs. In this study, a PMC remanufacturing process was developed by classifying the failures exhibited by a used PMC into four levels, followed by determining the feasibility of remanufacturing the PMC. The developed remanufacturing process consisted 11 steps according to the failure levels of the used PMC. The performance of a new PMC and that of the PMC remanufactured by our proposed method were evaluated and compared. PMC remanufacturing is an eco-friendly technology that involves less production steps, reduces raw-material consumption, reduces environmental pollution, and aids in resource saving.

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.

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.

The purpose of this study is to suggest better alternatives for the Anchovy Boat Seine Fisheries through financial statement analysis, ROI, Index method and the Circle chart method. The main results are as followed. First, the Anchovy Boat Seine Fisheries in terms of sales growth, profitability and activity ratios is worse off than the Offshore Fisheries. Therefore, in this situation the Anchovy Boat Seine Fisheries should establish a marketing strategy, work on sales promotion and aim for cost reduction. Second, concerning the total assets growth, liquidity, and safety ratios, the Anchovy Boat Seine Fisheries is better than the Offshore Fisheries. Third, it turns out that the ROE of Anchovy Boat Seine Fisheries has a large negative value. The reason for this negative value is due to the aggravation of net income in sales ratio and total assets turnover ratio. Fourth, the total score of Anchovy Boat Seine Fisheries measured by the Index method is -58.02. It means that the business performance of Anchovy Boat Seine Fisheries is quite bad and poor. A bad business performance results in the decrease of sales growth, the turnover ratio, and fisheries sales income ratio. Fifth, according to the circle chart method, the overall business condition of the Anchovy Boat Seine Fisheries is quite bad. The sales growth, fisheries sales income, and fisheries income to total assets ratio are lower than the Offshore Fisheries. We suggest the Anchovy Boat Seine Fisheries to establish marketing strategy, sales promotion and cost reduction in order to achieve better business performance conditions.

한·중 증권시장 발전사의 비교분석

문성주(Seong-ju Moon),김홍배(Hong-bae Kim),김우수(Woo-su Kim) 한국경영사학회 2016 經營史學 Vol.80 No.-

본 논문은 비교사적 관점에서 한·중 증권시장의 발전사를 시장형성기, 기반구축기, 국제화 및 시장확장기 등으로 나누어 살펴보고 발전 단계별로 비교분석하고자 한다. 주요한 분석결과는 다음과 같다. 첫째, 한국의 경우 증권시장 시장형성기에 일본의 영향을 많이 받았고, 증권시장도 전쟁 및 국가재건 자금을 조달하기 위해 형성되었다. 이에 반하여 중국은 공산당의 정책에 영향을 많이 받았는데 1978년 개혁개방정책 이전에는 모든 증권시장이 폐쇄되어 한국보다 증권시장발달이 상대적으로 늦어졌다. 둘째, 한국 증권시장의 기반은 1956년 대한 증권거래소 설립 및 1962년 증권법이 제정되면서 조성되었다. 이에 반하여 중국 증권시장의 기반은 1990년 상해 및 선전 증권거래소 설립 및 1998년 증권법이 제정되면서 조성되었다. 셋째, 한국 증권시장의 국제화는 1981년 재무부의 자본시장 국제화 장기계획에 의해 시작되었으며 1998년 5월에 외국인 직접투자가 전면 허용되었다. 중국 증권시장의 국제화는 2001년 WTO가입을 계기로 총 네차례의 시장개방 조치를 통해 진행되었다. 넷째, 한국이 중소·벤처기업을 육성하기 위해 코스닥시장 및 코넥스시장을 개설한 것과 유사하게 중국은 중소기업판(中小板), 차스닥(創業板) 및 신삼판(新三板)을 개설하였으며 한국 파생상품시장에서는 주가지수선물 및 옵션의 거래량이 상품선물보다 상대적으로 높은데 반하여 중국에서는 상품선물 거래량이 금융선물보다 상대적으로 높았다. 마지막으로 1992년 한중수교를 계기로 한·중 증권시장의 상호 연계성은 더욱 강화되고 있음을 알 수 있었다. <영어 초록> This paper focus on the developmental history of Korean and China securities markets on the view of comparative perspective into market formation, infrastructure construction, internationalization, and market expansion. The main results are as follows. First, The formation of the securities market in Korea was influenced by Japan and the securities market was formed to finance the war and national reconstruction. China securities market was influenced by the policies of the Communist Party. Prior to the reform and opening policy in 1978, all securities markets were closed and the development of the securities market was relatively slower than that of Korea. Second, The foundation of the Korean securities market was established with the establishment of the Korea Stock Exchange in 1956 and the enactment of the Securities Act of 1962. The foundation of the Chinese securities market was established in 1990 when the Shanghai and Shenzhen securities exchanges were established and the Securities Act of 1998 was enacted. Third, The internationalization of the Korean securities market began in 1981 by the Ministry of Finance `s long - term plan for internationalization of capital markets. In May 1998, foreign direct investment was fully accepted. The internationalization of the Chinese securities market has been completed through four market opening measures with the accession to the WTO in 2001. Fourth, Similar to Korea`s opening of the KOSDAQ and KONEX markets to foster small and medium-sized venture companies, China has opened Small Medium Business Board, CHASDAQ and New Third Board. In the Korean derivatives market, trading volume of stock index futures and options is relatively higher than that of commodity futures, while commodity futures trading volume in China is relatively higher than financial futures. In conclusion, we can conclude that the interlinkage between Korea and China securities market has been strengthened in 1992 as a result of Korea-China diplomatic relations.
