This work investigates factors that may affect the choice of real options by ERP project managers. Financial theory suggest that these factors include risk-free interest rate, time to maturity, volatility of net present value, and options exercise price. Other than these factors, we are interested in the exogenous risks related to external uncertainties about technological cost, user learning and consulting, and so forth and we argue these risks should have a significant impact upon the volatility of net present value. To validate these factors empirically, we collected survey questionnaires from ERP project managers in Korea. We find that perceived exogenous risks with regard to ERP projects influence volatility and additionally find that ERP project managers prefer contract options of the project when the volatility of the project is expected to be high. We expect that this work will not only validate theoretical propositions but help project managers consider ERP options strategically based on these factors.

The Hongseong-Gun school food service center (Hongseong SFSC) that is managed directly by local government is supplying local environmentally friendly foods from 2014. This study aimed to analyze a case on Hongseong SFSC and to propose improving directions. Hongseong SFSC showed higher supply ratio (67.4%) of local environmentally friendly foods compared to the other centers. The operation effects of this center are reliably price of farmer's products, increased consumption of local agri-products, school food confidence, and so on. But there are many problems on this operation. Improvement directions of SFSC for local food system are as follows: Firstly, the supply range of foodstuffs is needed to establish quality standards to increase foodstuffs quality. Secondly, guidelines for creating a fair commission fee structure should be established. Thirdly, the contract issues between the center and schools need to be resolved by governance system. Fourthly, local environmentally friendly agricultural cultivation and cropping systems are required to establish reliably supply of farmer's products.

Bidding systems in the domestic public construction work have been amended many times since the lowest-bidding system was implemented in 1951. However, this hasn't had much success. Competition in technical development among companies has declined as the contracts for buildings are given to company which submits the lowest price without considering traits of projects. In addition, as the construction market turns to the limitless competition system due to FTA(Free Trade Agreement), advanced techniques are needed to promote the national competitive power. Considering the needs of the times, Korean government announced that "Best Value Contract (Design-Bid-Build)" and "Bridging Contracts (Design-Build)" are included to 4 existing bidding systems in October 2007. Thus this study aims to suggest devised the evaluation criteria including major items for evaluating bidders, in order to establish and revitalize the best-value bid system successfully.

The purpose of this article is to search stakeholders' recognition related to Fire Construction Surveillance system; a client(order), fire fighting officer, supervision company, construction company, design company, other. The paper provides 4 important things. Firstly, a client(order) suggested the lowest recognition in the needs about the need of separation order, that of contract for any construction work limited registered companies, and that of standard price for engineering.. Secondly, the design company is lowest recognition in guidance and control participating in construction-design phase. Thirdly, the design company is lowest in adjustment about manpower-allocation according to allocation criteria of technical manpower. Fourthly, a client(order) and supervision company are relatively lower than other stakeholder in necessity on special education and training system for auditor in fire protection construction. Almost all related matters are related to more or less stakeholders' interest.

건설교통부에서는 설계시공일관사업을 포함한 총공사비 100억원 이상인 모든 공사에 설계VE 적용을 의무화하고 있다. 현행 설계시공일관사업에서는 입찰을 통해 확정된 총액금액으로 설계가 진행되어 실시설계단계에서 VE의 실시 명분이 미흡한 상태이다. 그러므로 설계시공일관사업에서 설계VE을 활성화하기 위해서는 설계VE 적용 결과에 따른 절감액의 배분이 이루어져야 한다. 이에 본 연구에서는 현행 설계시공일관방식의 특성과 설계VE 적용의 문제점을 파악하고, 설계시공일관사업에서 설계VE 적용의 효과를 극대화할 수 있는 인센티브의 활용방법을 제안한다.

Re-auction happens when a bid winner defaults on the payment without making second in-line purchase declaration even after determining sales permission. This is a process of selling under the court's authority. Re-auctioning contract price of real estate is largely influenced by the real estate business, real estate value, and the number of bidders. This paper is designed to establish a statistical model that deals with the number of bidders participating especially in apartment re-auctioning. For these, diverse factors are taken into consideration, including ratio of minimum sales value from the point of selling to re-auctioning, number of bidders at the time of selling, investment value of the real estate, and so forth. As an attempt to consider ambiguous and vague factors, this paper presents a comparatively vague concept of real estate and bidders as trapezoid fuzzy number. Two different methods based on the least squares estimation are applied to fuzzy regression model in this paper. The first method is the estimating method applying substitution after obtaining the estimators of regression coefficients, and the other method is to estimate directly from the estimating procedure without substitution. These methods are provided in application for re-auction data, and appropriate performance measure is also provided to compare the accuracies.

The purpose of the study is to review the evolutional process of the U.S. broiler industry into the integrated production and marketing systems and to examine the factors influenced such a structural change over the Past half a century. The study is also carried out under the consideration that the experience gained by the integrated U.S. broiler industry could be utilized in applying the system to any non-integrated broiler industries like one in Korea. The U.S. broiler industry has been prevailed in the typical independent operation of all stages, from factor supply through growing to dressing and marketing until such time as growers began to suffer from financial difficulties right after the end of the World Wat II due mainly to lowered price of broilers stemmed from whopping decrease of the demand, which eventually reflected to the allied agribusiness sectors. The feed business field was the first reactor to this situation so that a kind of measures was taken to cope with the problems faced in such a way to provide extended credit on feeds first and help obtain chicks or sell broilers later. This trend has been practiced for broiler related agribusiness through late 1940's to work together with growers by coordinating its function between two or more stages involved in broiler production and marketing process as a means of spreading risk and sharing profit between stages Participated. The integrated system and contract farming thus became Popular across the country through mid 1950's.

In recent years, Korean rice must compete with the rice of advanced countries under Doha Development Agenda(DDA) and free Trade Agreement(FTA). Therefore we should find more active and positive solution in rice industry according to the inncreasing power of international pressure. Increasing rice production was the most important policy during the past food-deficient days, but recently, with overproduction of rice, various circulation system by the brand(price)-differentiation should be settled in a recent market of Korea. Nowadays, some advanced rice farmers and Rice Processing Complex(RPC) managers developed new brands of rice with high-quality, adding healthy materials and environment-friendly farming methods. Therefore, the future strategy of making a new brand rice should be planned including selection of rice variety, cultural and post-harvest techniques, circulation and processing methods to compete against foreign rice. And environment-friendly farming is also recommendable for food safety and differentiate from imported rice. For the purpose of successful brand-rice, the following points might be considered. Firstly, selection of good quality rice and continual development of good variety must be conducted for the differentiation of Korean rice from foreign rice. Secondly, a special contract between producer and consumer with functional-rice, organic filming-rice, specific-rice will be recommendable. Thirdly, improvement of post-harvest management and milling system are necessary for the production of differentiated-rice. Fortunately, standard of inspection, rules of description for brand-rice must be developed by a more scientific examination in order to settlement of trust for consumer. Finally, provincial or regional-representative brand rice must be settled and conducted for the development of agreement market system between producer and consumer.
