As a system complexity increases and technology innovation progresses rapidly, leasing the equipment is considered as an important issue in many engineering areas. In practice, many engineering fields lease the equipment because it is an economical way to lease the equipment rather than to own the equipment. In addition, as the maintenance actions for the equipment are costly and need a specialist, the lessor is responsible for the maintenance actions in most leased contract. Hence, the lessor should establish the optimal maintenance strategy to minimize the maintenance cost. This paper proposes two periodic preventive maintenance policies for the leased equipment. The preventive maintenance action of policy 1 is performed with a periodic interval, in which their intervals are the same until the end of lease period. The other policy is to determine the periodic preventive maintenance interval minimizing total maintenance cost during the lease period. In addition, this paper presents two decision-making models to determine the preventive maintenance strategy for leased equipment based on the lessor's preference between the maintenance cost and the reliability at the end of lease period. The structural properties of the proposed decision-making model are investigated and algorithms to search the optimal maintenance policy that are satisfied by the lessor are provided. A numerical example is provided to illustrate the proposed model. The results show that a maintenance policy minimizing the maintenance cost is selected as a reasonable decision as the lease term becomes shorter. Moreover, the frequent preventive maintenance actions are performed when the minimal repair cost is higher than the preventive maintenance cost, resulting in higher maintenance cost.

금융회사가 개인정보를 수집하기 위해서는 법률에 정해진 내용을 소비자에게 명시적으로 알리고 사전 동의를 받도록 되어 있다. 그 결과 금융상품이 복잡해지고 다양해짐에 따라 '개인정보제공 동의서' 내용도 복잡해지고 분량이 많아지게 되었다. 특히 인터넷과 모바일의 경우 화면 크기의 제약으로 글씨가 더 작아지면서 더욱 이해하기가 힘들어졌다. 이것은 개인정보를 수집하는 거의 모든 기업이 비슷한 상황이어서, 서비스를 이용하는 소비자 입장에서는 동의 내용을 이해못한 채 습관적으로 동의하는 모순이 생기고 있다. 본 연구에서는 금융회사 인터넷 홈페이지를 통한 합리적인 개인정보 수집 및 이용 동의 정책 수립 모델을 제시하기 위해 국내외 법제도를 고찰하여 문제점을 도출하고 개선 방안을 제시한다. 또 연구를 통해 선정된 평가요인을 AHP(Analytic Hierarchy Process)방법을 이용하여 의사결정 모델과 공식을 제시하고 검증한다.

This study focuses on the roles of family and parents as primary environments for character education of children and adolescents, examines surrounding micro and macro environments in a bioecological model, and explores parent support methods for restoring character education in family. For this study, we had interviews with 54 parents(44 mothers & 10 fathers). Through the interviews we found difficulties of character education in family and analyzed them in children and teenagers, parents, school, and social-cultural dimensions based on the bioecological model. On the basis of the parents' perception for these difficulties, we proposed how to support the roles of family and parents for recovering character education in family. The policy methods were propsed in family, school, and society dimensions. This study is meaningful in that it suggests evidence base for making the parent support policy.

Purpose: This study aims to analyze the factors affecting the agenda-setting process and the formation process of school-based mental health policies by applying a policy stream model. Methods: For this purpose, Kingdon's policy stream model was used as the analytical framework. Results: First, when establishing a school-based mental health policy, the agenda was set going through unpredictable and nonlinear changes. Second, for the school-based mental health policy to be selected onto the agenda and to be developed and implemented as an actual policy, the role of policy makers was considered most important in the process. Third, the policy window for school-based mental health policy was closed around the year 2013. Finally, an analysis of the school-based mental health policy stream identified two key features. One is that the school-based mental health policy first emerged when school violence prevention policy expanded its scope into relevant neighboring policies. The other is that the school-based mental health policy has taken shape through a linear decision-making process (being put on the government's agenda, searching for an alternative, selection, and implementation) during the policy implementation period after it has been selected as an alternative policy. Conclusion: Conclusions can be summed up as follows. The school-based mental health policy needs continuous development and improvement in case the window for the policy may open in the coming future. The government's support is needed to draw policy makers' interest and participation who play the biggest role in establishing policies.

Purpose: This study was done to analyze the contents of nurses' ethical decision-making in four of hypothetical dilemma cases using the Cameron's Ethical Decision-Making Model of 'Value, Be, Do'. Method: Sixteen nurses who work at ICU at present or worked before, participated from April 10 to May 10 in 2002. The participants were interviewed three times each and for 40 minutes at once, with a structured questionnaire at their working places and locker rooms. The data was analyzed by a procedure of qualitative content analysis into three categories; what should I value, who should I be, what should I do. Result: 1) In consistency, most of subjects showed a unified voice in 'Value, Be, Do'. Exceptionally 8 subjects showed inconsistency such as 3 in active treatment to the incurable patients(case 1), 1 in treatment truth-telling to the terminally ill patients(case 2), 3 in conflict with uncooperative doctors(case 3), 3 in dying patients and euthanasia(case 4). Only one subject showed inconsistency in 3 dilemma cases. 2) Closing the interview procedure, the subjects evaluated Cameron's Model as it would help them build consistent value, carry right action, and cope to conflicts. Conclusion: On the basis of the results, it is recommended that nursing ethics should adopt the ethical decision-making model, and be applied to the curriculum of nursing colleges and continuing education program for clinical nurses.

This paper investigates how public opinion has affected the United States Senate's votes on arms control treaties. Applying multilevel modeling with post-stratification to national polls, this paper produces estimates of state-level opinion on both the New Strategic Arms Reduction Treaty of 2010 and the Comprehensive Test Ban Treaty of 1999. Using these estimate, this paper examines the relationship between public opinion and the Senate's votes on the treaties. This paper finds that the influence of public opinion was mostly significant but indirect. These findings indicate that some version of the delegate model of representation is more applicable to foreign policy making in Congress.

This paper explores the ways by which the authority concerned with nuclear energy policy-making in Korea can strengthen its organisational sustainability from long-term perspective. In doing so, it applies the system dynamics approach to predict what would happen to the organisational sustainability of the nuclear energy authority in the future. In the process of analysis, it also draws causal loop map of components contained in the simulation model and constructs user-interface simulation model. It shows different predicted future values regarding organisational sustainability of the nuclear energy authority in Korea and puts forward some policy implications for practitioners and academics involved in nuclear energy policy.

Providing free primary care to everyone is an important goal pursued by many countries under universal health care programs. Countries like India need to efficiently utilize their limited capacities towards this purpose. Unfortunately, due to a variety of reasons, patients incur substantial travel and out-of-pocket expenses for getting primary care from publicly-funded facilities. We propose a set-covering optimization model to assist health policy-makers in managing existing capacity in a better way. Decision-making should consider upgrading centers with better potential to reduce patient expenses and reallocating capacities from less preferred facilities. A multinomial logit choice model is used to predict the preferences. In this article, a brief background and literature survey along with the mixed integer linear programming (MILP) optimization model are presented. The working of the model is illustrated with the help of numerical experiments.
