Recently, a lot of companies intend to make spin-offs as the Internet usage is proliferating in the business area. A spin-off means a small but autonomous company which is thought to show higher profitability rather than it stays under the influence of a mother enterprise. To prove our hypotheses, we collected questionnaire data from 104 companies considering spin-offs. From experiments with Factor Analysis, we found that there exist four factors which decision-makers should consider before deciding spin-offs such as competence of unit, competence of mother company, competence of spin-off company, and support of mother company. After massive experiments with Regression Analysis we also found that there are significant three performance factors such as competence of unit, competence of spin-off company, and support of mother company. The survey also asked about three potential strategies that they may have been following for achieving business objectives: Cost leadership, Focus, and Differentiation, Six benefits factors emerged from this study: External competitiveness, Internal competency, Productivity, Change, Cost saving, and Improvement. External competitiveness was the most important benefit, and it predicted a Differentiation and Focus strategy. Productivity and Improvement also predicted a Differentiation strategy. External competitiveness, Change, and Cost saving predicted a Cost leadership strategy. However, organizations followed Differentiation and Focus strategies significantly more than Cost leadership. The assessment thus sheds light on the link between information strategy and spin off. We hope that based on our results, many companies considering a spin-off can make a right decision and expect higher performance in a turbulent business environment.

This study is aimed at identifying the decision making criteria as B/C ratio, IRR and NPV based on the expected benefits and costs of the land utilization and promotion projects which have implemented to improve agricultural structure under WTO system. To carry out the objectives of the study, Sinseok project area located at Dangjin district, Chungnam province was selected. Sinseok project area has 306.2 ha of paddy area with 172 farm households. The project area will be operated by the 33 specialized farm households after completion of the project which will have 20 years of economic life. After completion of the project, farm size will be increased from 1.8ha to 9.3ha. Land intensity of the project area will be increased by 10%. Increase of land productivity and cost saving due to the labor saving technology as farm mechanization will be expected. According to the survey results, the annual amount of production cost savings per farm was estimated 3.884million won and increased total farm income was expected about 43.8million won per year. The total expexted project benefits was expected 174million won per year. The project costs to promote land utilization and structural change consisted of handling charges, and direct payment for land movility. The decision making criteria representing economic feasibility of the project such as B/C ratio, NPV and IRR were estimated 2.49, 483million won and 30% respectively when the cut-off rate was taken into account 10%. In conclusion, the land utilization and promotion project proppeled by the Korean Government under the agricultural land law is considered economically feasible from the view points of expected project benefits and costs. Accordingly the project have to be implemented more strongly under the G't financial support considering WTO and UR negociation which were aimed at achieving the free trade and improvement of international competitiveness of farm products.

Recently, Korea aimed to increase water use efficiency by implementing integrated management according to the water management unification policy. Considering the enormous use of water resources in the agricultural sector, it is necessary to efficiently conserve water in terms of demand management by intensifying the stakeholders' involvement and awareness campaigns. The existing agricultural water management system in Korea is based on a top-down approach by which the government agencies directly plan budgets and policies to be enforced on and implemented by farmers, with little to no involvement of farmers in the decision-making process. However, this process has hindered the desired water resources management and the water conservation goal at the field level. Moreover, the limited research on water governance operations focusing on agricultural water creates a knowledge gap, particularly in Korea. Thus, it is necessary to investigate water governance cases with successful implementations in agricultural and rural areas to identify the factors applicable to domestic governance in Korea. In addition, a more systematic governance model should be established by identifying the subjectivity of the stakeholders' involvement in agricultural water governance. Therefore, this study proposed a new bottom-up model for agricultural water governance, which aims to raise the problem of autonomous water governance while promoting stakeholders' voluntary participation in agricultural water management and reflecting farmers' involvement in the decision-making process. Moreover, if agricultural water governance is expanded nationwide by reflecting agricultural and water resource policies in the future, it is believed that positive effects can be achieved in increasing utilization efficiency and securing sustantiality through agricultural water saving.

Purpose: The aim of this study is to identify the legal concept of a license and a qualification for health care personnel. We analyze the appropriateness of the qualification for the first-class paramedics and the sufficiency of 3-year job experience in substitution for college level academic major. Method: We reviewed Laws on Healthcare which stipulate academic and career qualifications for healthcare personnel for whom college-level academic training and job experience to get a license. Results: There is no legal consideration which permits major and educational background substituted by job experience. Only third-class hygienist who graduated from a high school or the equivalent with 3 year job experience can apply for first-class hygienist' national license examination without educational requirements. However, it is nothing to compare with first-class paramedics because the work of hygienist is not directly related to patients care and there is no need of doctor's supervision for hygienist' job. Paramedics have a major role in saving emergency patients in making prompt decision, applying appropriate emergency treatment, securing intravenous route, managing intubation, applying defibrillator, and etc. Conclusion: Ministry of Health & Welfare should grant license to paramedics and annul replacement of academic major background. In addition, it is imperative to broaden the scope of paramedics' job so that they can guarantee patient's life saving in emergency situation with quality major curriculum of college level.

Traffic accident involved with the vulnerable pedestrian is one of the significant concerns, which has higher possibility of fatality than any other accident types. Worldwide significant efforts have been made to establish a vehicle safety regulation, which is internationally agreed, in order to reduce pedestrian casualties in pedestrian-vehicle collisions. One of the key issues in deriving the regulation is how to effectively select the parameter values associated with the regulation. This study firstly develops a method to optimize parameter values. An optimizing problem in terms of maximizing safety benefits, which are life-saving effects by the regulation, is formulated. Extensive actual accident data analysis and simulations are conducted to establish several statistical models to be used in the proposed optimization procedure. A set of parameter values that can produce maximizing life-saving effects is presented as the outcome of this study. It is expected that the proposed method would play a significant role in determining parameters as a decision support tool toward ensuring better pedestrian safety.

Sustainability continues to gain traction in all industry sectors as people become aware of the advantages of green products. The voluntary use of green products in buildings in the United States continues to grow due to long-term cost saving and the ecological benefit to nature. The voluntary installation of green products is associated with end-users' expectations and perceptions including cost saving, sustainable behavior, and social responsibility. Although involuntary use of green products has similar expectations and perceptions, the installation decision is not based on the goodwill from end-users. This paper surveys college students to capture current experience levels, expectations, and perceptions in regard to green products and/or sustainability and to understand their attitudes about involuntary use of a green product. The installation of low water pressure showerheads in a dormitory provides data to support perception, expectation, and future direction of adoption of green products in public buildings. This information may be used to facilitate sustainable behaviors among involuntary groups regarding to the adoption of green products. The primary objective of this paper is to investigate the college students' perception of a green product, particularly when the students are involuntarily exposed to the green products. As a secondary objective, the paper also attempts to address the college students' general understanding on sustainability and green products. The findings of this study could support the growing importance of sustainable behavior among higher education beyond social responsibility and provide a benchmark against which to improve future change while fostering sustainable behaviors over time among the public.

에너지의 소비가 큰 화학공장은 공정 자체가 가지는 비선형성, 불안정성등과 여러 가지 외란으로 인한 최적의 상태로 운전되고 있지 못하다. 이를 개선하기 위해 공장 전체 최적화를 수행하게 된다. 공장 전체를 대상으로 하는 최적화에는 경제적으로 영향을 주는 조절 변수가 많기 때문에 조절 변수의 개수를 최적으로 선정하는 문제는 중요하다. 경제적으로 영향을 주는 조절 변수를 모두 사용하여 최적화를 할 경우 최적화하여 나온 결과를 운전 조건에 반영할 때 많은 운전조건이 바뀌게 되므로 운전 조건의 변화에 따른 비용이 증가하게 된다.본 연구에서는 TPA(Terephthalic Acid) 공정을 대상으로 공장 규모 최적화를 하기 위하여 운전 비용에 영향을 주는 최적화 조절 변수를 최적으로 선정하기 위한 방법을 제시하였다. 즉, 모델을 만든 후 운전비용에 영향을 주는 조절 변수의 정도를 민감도 분석을 통해 알아 봄으로써 최적화할 때 운전 비용에 영향이 큰 변수들만 사용하는 것이다. TPA공정에서는 본 연구에서 제시한 방법에 의해 3개의 조절 변수를 선정하였고 선정된 변수로 최적화 한 결과 추가적인 설비 투자나 물리적인 개조 등이 없이 연간 약 3억 5천 만원의 에너지 비용 절감이 기대 된다.
