We are in an era of global business called one world market. These environments require Korean firms to face an unlimited competition and to resolve their dispute by ADR. Few study, however, on the ways of dispute settlement under the changed international business environment has been done. Thus the major purposes of this study are to investigate Busan's trading companies' preference on the dispute resolution ways. Based on the results of my study, I suggest Busan's trading companies the following guidelines. First, Busan's trading companies should improve their negotiating power by using internet trade and problem solving ability through the establishment of claim information system. Second, They should write contract. Lastly, they should investigate their counterparty's credit.

본 논문은 세계적 수준의 양적인 성장에도 불구하고 여러 가지 문제점을 갖고 있는 국내의 장내 파생상품시장에 대한 바람직한 개선방향을 모색하고자 한다. 우리나라의 장내 파생상품시장에서는 외가격 또는 극외가격의 거래비중이 높고, 미결제약정 당 거래량이 많아 포지션을 짧게 보유하는 투기적 거래의 성향이 강한 것으로 보인다. 또한 외국에 비해 개인투자자의 파생상품시장 참여가 높은데 이로 인한 손실이 지속되고 있고 개인투자자들의 부가 기관 및 외국인투자자들에게 이전되고 있다. 이처럼 여러 문제점을 갖고 있는 장내 파생상품시장에 대한 바람직한 정비방향을 모색하기 위해 투자자보호를 위한 행위규제 측면에서 향후 규제체계 개선방향에 대한 여러 가지 방안을 제안한다. 우선 투기성향의 거래를 완화하기 위해서는 현재 외가격 위주로 거래되고 있는 코스피200옵션시장을 등가격 위주의 시장으로 유도할 필요성이 있다. 이를 위해 등가격 거래에 대한 거래수수료 할인 또는 면제, 등가격 종목에 대한 시장조성자제도 도입 등을 고려할 수 있다. 개인투자자 보호를 위해서는 전문투자자와 개인투자자에 대한 차등 규제, 기본예탁금 관리 강화, 위험관리 교육 및 모의거래 기회 확대 등을 시행 가능한 방안으로 제안하고자 한다.

Participation in power trading using surplus power is considered a business model active in the domestic energy trade market, but it is limited only if the legal requirements according to the type, capacity, and use of the facilities to be applied for are satisfied. The hydrogen residential demonstration model presented in this paper includes solar power, energy storage system (ESS), fuel cell, and water electrolysis facilities in electrical facilities for private use with low-voltage power receiving system. The concept of operations strategy for this model focuses on securing the energy self-sufficiency ratio of the entire system, securing economic feasibility through the optimal operation module installed in the energy management system (EMS), and securing the stability of the internal power balancing issue during the stand-alone mode. An electric facility configuration method of a hydrogen residential complex demonstrated to achieve this operational goal has a structure in which individual energy sources are electrically connected to the main bus, and ESS is also directly connected to the main bus instead of a renewable connection type to perform charging/discharging operation for energy balancing management in the complex. If surplus power exists after scheduling, participation in power trading through reverse transmission parallel operation can be considered to solve the energy balancing problem and ensure profitability. Consequentially, this paper reviews the legal regulations on participation in electric power trading using surplus power from hydrogen residential models that can produce and consume power, gas, and thermal energy including hybrid distributed power sources, and suggests action plans.

After IMF situation, the money market environment is changing rapidly. Therefore, many companies including financial institutions and many individual investors are concerned about forecasting the money market, and they make an effort to insure the various profit and hedge methods using derivatives like option, futures and swap. In this research, we developed a prototype of forecasting system for KOSPI 200 option, especially call option, trading using artificial neural networks(ANN), To avoid the overfitting problem and the problem involved int the choice of ANN structure and parameters, we employed the ANN ensemble approach. We conducted two types of simulation. One is conducted with the hold signals taken into account, and the other is conducted without hold signals. Even though our models show low accuracy for the sample set extracted from the data collected in the early stage of IMF situation, they perform better in terms of profit and stability than the model that uses only the theoretical price.

Purpose: The Emission Trading Scheme (ETS), which enables structuring emission credits as a financial product, is taking a crucial position of global collaboration against climate change. Previous studies that have covered ETS subjects from the macro perspective contribute to facilitating legal enactment of this scheme. However, they have rarely addressed challenges aligned with issues arising from labor burdens for ETS works from the business perspective. Research Design, data and methodology: This study presents conceptual models that are expected to help design an electronic system. The study model contains four modules: emission allocation, data interface, reduction technology sharing, and emission trading. Two validation approaches, the Analytic Hierarchy Process (AHP) and regression analysis, are applied in confirming the feasibility of the proposed model. Results: This study suggests an IT system methodology to help improvement of the current K-ETS mechanism. In particular, this study addresses effectiveness for real businesses and the adaptability of this mechanism to other nations. Conclusions: The proposed IT platform diagram can contribute to successful operation of ETS by providing multiple benefits to participating companies through in-house allocation mechanisms, the soft-landing of ETS adoption to participating companies through reduction of technology-sharing, group purchases, and transaction costs through the trading system.

The study aims to analyze the adaptation strategies and resilience of tobacco farmers to face unfavorable trading system. The research method refers to a qualitative approach with phenomenological models and case studies. The findings revealed tobacco farmers in Jember developed various adaptation strategies and resilience through farmer group organizations, partnerships, self-capacity building and access to financial institutions based on economic, social, cultural, and experience values from various sources and interactions among fellow tobacco farmers. The tobacco trading system, which is left to the market mechanism, results in low bargaining power of farmers, this encourages tobacco farmers to develop various adaptation and survival strategies, namely through collective activities of farmer groups, partnerships and self-development and access to financial institutions. Dealing with the unfavorable tobacco trading system, tobacco farmers do not switch to other commodity farming but adapt and make Jember a center for tobacco production in East Java and Indonesia. From this findings, it suggests to the government as the regulator does not only provide subsidies for tobacco farmers, but also must provide various technical assistance to increase the ability of tobacco farmers. More importantly, regulations must be made benefit tobacco farmers other than corporations so that equality can be enjoyed by tobacco economy players.

In this study, the differences of institutional development processes of fishery products wholesale markets were compared between Korea and Japan in order to suggest improvement direction of trading system in Korea. The wholesale markets have shrunk while wholesale and distribution has been becoming larger in size in both countries. A summary of differences in the wholesale market trading systems between Korea and Japan is as follows: first, middle wholesalers play pivotal roles in wholesale transaction in Korea, and wholesale corporations take such roles in Japan. Second, most wholesale corporations take charge of listing in Korea whereas such corporations are in charge of buying in Japan. Third, Korea has high proportion of auction for transactions, in contrast to Japan with high proportion of relative transactions. Forth, Korea maintains more sales within the wholesale markers and has more small and medium customers than Japan. Finally, Korea investigates inside causes to find solutions for the decreased competitive power of the wholesale market, whereas Japan copes with the problem by searching for outside customers. To seek solutions for the decreased competitiveness of Korean fishery products wholesale markets, middle wholesalers' consignment should be limitedly allowed, and improvement direction of wholesale corporations should be investigated in the future study.

Pair trading is a statistical arbitrage investment strategy. Traditionally, cointegration has been utilized in the pair exploring step to discover a pair with a similar price movement. Recently, the clustering analysis has attracted many researchers' attention, replacing the cointegration method. This study tests a clustering-driven pair trading investment strategy in the Korean stock market. If a pair detected through clustering has a large spread during the spread exploring period, the pair is included in the portfolio for backtesting. The profitability of the clustering-driven pair trading strategies is investigated based on various profitability measures such as the distribution of returns, cumulative returns, profitability by period, and sensitivity analysis on different parameters. The backtesting results show that the pair trading investment strategy is valid in the Korean stock market. More interestingly, the clustering-driven portfolio investments show higher performance compared to benchmarks. Note that the hierarchical clustering shows the best portfolio performance.

클라우드 컴퓨팅은 정보의 다양성과 빅데이터를 IT자원을 이용하여 처리할 수 있는 컴퓨팅 개념이다. 정부는 신재생에너지를 활용한 전력생산을 장려하기 위해 RPS를 시행하였고 시스템을 구축하여 지리적으로 분산되어 있는 빅데이터를 수집하여 운영하고 있다. RPS제도를 이행하는 발전사업자들은 의무할당량 중 REC 부족분을 타 발전사업자들로부터 REC를 구매하여 조달해야 한다. REC는 자율시장에 근거하여 거래되고 있고, 매매가격의 편차가 크기 때문에 RPS 빅데이터를 통해 형평성있는 REC가격을 예측할 필요가 있다. 본 연구에서는 부정확한 가격추이와 규칙을 정량적으로 표현하여, 클라우드 환경에서 퍼지기반으로 REC가격을 예측하는 방법을 제안한다. 클라우드 환경에서 RPS 빅데이터를 통한 상호연관성과 가격결정에 영향을 주는 변수들에 대한 분석이 가능하고 시뮬레이션을 통해 REC 가격을 예측할 수 있다. 클라우드 환경에서 퍼지로직은 매물수량과 매매가격을 이용하여 투명성있는 REC 가격을 예측하고 장기적으로 수렴된 가격을 제시할 것이다.
