Due to a waste of energy in korea, about 525,000 which are 75 percent of total buildings are at least 15 years old buildings that need remodeling. There are two current remodeling systems. One is a remodeling system to reduce a waste of resources from the reconstruction. The other is a green-remodeling system aimed to energy savings and reducing environmental costs. This study is to analyze quantitatively these current systems with respect to the cost-benefit caused by the life cycle and suggests the political and institutional implications through the interpretation of the results. For a quantitative analysis, we analyzed reducing maintenance costs and rent benefits with simulation by using opportunity costs, construction costs, plan costs and supervision costs as expense variables and using the reduced floor area ratio, institutional incentives, energy, water resources and certified emission reduction(CER) as benefit variables. As a result of the empirical study, the green-modeling was more beneficial in the field of environment such as the energy savings, however, the final benefits of remodeling which has no green building certification costs but more floor area ratio incentives were more economical. The green-remodeling system focused on reducing environmental costs and energy savings needs a equatable institutional incentive system.

This paper provides a simple microeconomic model of terrorist attcks and anti-terrorism policies. The terrorists can be characterised as rational actors, choosing between legal activities and terrorist activities to promote their political goals. Since their resources are limited, one can think of anti-terrorist policies by examining how such policies affect the objectives and constraints of terrorists. Deterrence policy seeks to reduce terrorist attacks by raising the cost of undertaking terrorist acts. Proactive policy aims at preventing attacks by destroying terrorists' resources (fund, personnel, leadership). This paper suggests another type of anti-terrorist policy which is to reduce the benefits of (or in other words, raising the opportunity costs of) terrorist acts. Such a policy is based on decentralisation in political decision-making and economic power.

This paper deals with new realizations of research, scientific development, managerial and economic optimizations for prefabricated building systems. In the literature, all scientific fields are worked out based on the efficiencies, costs, benefits, choice of execution design, technical demands, aesthetical point of view, as well as the total economics. In the present example of a school-building for communities in the third world, the following criteria have been regarded: The optimal superstructure of prefabricated concrete building systems; the particularity of countries of the Third World (e.g. the climate, the political and the economic conditions); the time for construction and necessary innovative developments for an economically optimized superstructure. Added to this are alternative construction-methods and costs for a simple but variable system which can be adapted to changing functions, where variability should be the main point. For example, a school building that is to be adapted by varying number of rooms to cater for the growing number of pupils.

한국사회에서 뉴미디어가 확산되는 과정에서 언론이 뉴미디어 의제를 어떻게 다루었는지 분석하고, 언론의 정치적 성향에 따라 뉴미디어 정책에 대한 태도가 어떻게 나타나는지 사설에 대한 네트워크 분석을 실시했다. 분석 결과, 언론과 정부의 정치적 성향 일치 여부가 정부의 뉴미디어 정책에 대한 태도와 밀접한 관계가 있는 것으로 나타났다. 보수 정권이 집권한 시기에 보수 언론은 뉴미디어 정책을 지지한 반면, 진보 언론은 정부의 정책을 반대했다. 이용자 관점, 사회적 관점, 정책적 관점에서 뉴미디어 의제를 분석한 결과, 신문사들은 뉴미디어 도입에 대한 찬반 입장, 정책에 대한 설명 등 정책적 관점에서 주로 접근했다. 사설이 뉴미디어 정책 효과에 대한 언론사의 의견을 밝히고 여론을 형성하는데 영향을 미치는 공간임에도 불구하고, 뉴미디어 정책에 사설대한 언론의 태도가 정부의 정치적 성향과의 일치 여부에 따라 다르게 나타난 것은 심각한 문제라고 할 수 있다. 뉴미디어의 도입과 확산에 정부의 투자와 인력 등 많은 자본이 투입되는 만큼 언론의 비판적인 시각이 중요하기 때문이다.

어느 한 집단이 정치적, 혹은 경제적으로 영향력이 클 경우 정책수단이 비록 효과적 혹은 효율적이라도 선택될 가능성은 현실적으로 낮다. 왜냐하면 그 과정에서 높은 정치적 비용이 수반되기 때문이다. 본 논문에서는 에너지를 소비하는 공해발생자와 공해피해자 간 타협을 도출하는 데 있어서 에너지보조금의 정치적 역할을 분석한다. Dolbear(1967)의 삼각 에즈워즈 상자 모형을 이용하여 정책선택이 두 집단의 소득분배와 후생수준에 미치는 영향을 중심으로 직접규제와 조세의 단일 정책수단 도입 효과와 에너지보조금을 포함한 정책조합의 효과를 비교한다. 분석결과, 에너지보조금이 사용됨으로써 공해발생자와 피해자 간의 타협 가능성은 증가하는 것으로 나타났다.

본 연구는 현재 사회적 문제가 되고 있는 도시재생 사업의 매몰비용 관련 인식 조사를 목적으로 실시하였다. 조사결과 지방정부, 중앙정부, 정치권, 조합원 및 토지 등 소유자 모두 매몰비용에 관하여 일정부분 책임과 부담 의무의 필요성이 있는 것으로 나타났다. 매몰비용에 대한 지원은 어느 하나의 주체에게 책임을 전가하기보다 정비 사업에 참여했던 주체 모두가 함께 책임을 통감하여 문제가 되고 있는 매몰비용의 부담과 해결 방안까지 공유해야하는 것으로 나타났다. 공공은 매몰비용에 대해 직접적인 지원보다는 간접적 지원(기반시설 부담, 세제혜택, 규제기준 완화 등)을 통하여 조합 등이 사업 추진의 지속 여부에 대하여 합리적인 선택을 할 수 있도록 유도하여야 하여야 할 것이다.

Global climate change brings environmental quality sensitivity, especially in developed countries. Developed countries use non-renewable energy sources intensively both in their own countries and in other countries, they make productions that cause an enormous rate of increase in CO₂ emissions and unsustainable environmental costs. This has increased the interest in environmentally friendly alternative energy sources. The aim of this study is to investigate the impact of nuclear energy consumption and technological innovation on environmental quality in G7 countries using annual data over the period 1970-2015. The Panel Threshold Regression Model was used for the analysis. Empirical findings have indicated that the relationship between nuclear energy consumption and carbon emissions differs according to innovation for nuclear power plants. It was also concluded that nuclear energy consumption reduces carbon emissions more after a certain level of innovation. This result shows that the increase in innovative technologies for nuclear power plants not only increases energy efficiency but also contributes positively to environmental quality.

이 논문은 1994년부터 2002년까지의 중국 상장기업의 데이터를 이용, 기업의 소유구조가 기업성과에 미치는 영향을 분석한 것이다. 특히 이 논문은 중국의 상장기업에 관한 새로운 주식 분류체계를 이용하여 기업 지배주주의 유형, 지배주주의 지분, 소주주들의 지분이 기업성과에 미치는 영향을 분석하고, 관련 가설을 검증하였다. 이 연구를 통해 얻은 결론은 다음과 같다. 주주로서 국가의 존재가 이윤보다는 고용을 유지하는 등 정책적 목표를 우선적으로 추구하거나 혹은 당과 정부의 개입을 초래함으로써 정치비용을 발생시켜 기업성과에 부정적인 영향을 끼칠 것이라는 주장은 적어도 정부지배 기업에게는 적용될 수 있음을 확인하였다. 아울러, 지배주주의 지분이 클수록 지배주주가 경영자에 대한 감시를 강화할 유인이 커지거나 혹은 지배주주가 소주주를 착취(expropriate)할 유인이 줄어 드는 것으로 인해 기업성과에 양의 영향을 미치게 된다는 주장은 민간기업 및 부분적으로는 시장화 국유기업에는 적용될 수 있는 것으로 나타났다. 마지막으로 소주주들은 경영자 감시에 적극적으로 나섬으로써 기업성과에 양의 영향을 미친다는 주장은 시장화 국유기업과 부분적으로는 민간 기업에는 적용될 수 있는 것으로 나타났다.

Relative value scales introduced in 2001 remarkably improved health insurance fee schedule, but current relative value scales have many problems. In the beginning the government intended to introduce 'resource based relative value scales(RBRVSs)' like USA, but political adjustment of RBRVS studied in 19.17 weakened the relationship between relative value scale and resource consumption. So unbalance of health insurance fees are existing till now. Also relative value was not divided to physician work and practice expense, and malpractice fee was not divided separately. To correct the unbalance of current relative value scales, the refinement project of health insurance relative value scales started in 2003. The project team divided relative value scales into three components, which are physician work, practice expense, malpractice fee. Physician work was studied by professional organizations like Korean medical association. To develop the practice expense relative value, project team organized clinical practice expert panels(CPEPs) composed of physicians, nurses, and medical technicians. CPEPs constructed direct expense data like labor costs, material costs, equipment costs about each medical procedures. The practice expense relative values of medical procedures were developed by the allocation of the institution level direct & indirect costs according to CPEPs direct costs. Institution level direct & indirect costs were collected in 21 hospitals, 98 medical clinics, 53 dental clinics, 78 oriental clinics, and 46 pharmacies. The malpractice fee relative values were developed through the survey of malpractice related costs of hospitals, clinics, pharmacies. Putting together three components of relative values in one scale, the final relative values were made. The final relative values were calculated under budget neutrality by medical departments, that is, total relative value score of a department was same before and after the revision. but malpractice fee relative value scores were added to total scores of relative values. So total score of a department was increased by the malpractice fee relative value score of that department This project failed in making 'resource based' relative value scales in the true sense of the word, because the total relative value scores of medical departments were fixed. However the project team constructed the objective basis of relative value scale like physician's work, direct practice expense, malpractice fee. So step by step making process of the basis, the fixation of total scores by the departments will be resolved and the resource based relative value scale will be introduced in true sense.

Nowadays, using math logic in great civil projects is considered by the clients to achieve the goals of project including quality optimization, costs, avoiding individual, emotional and political decision making, long-term and short-term goals and they are the main requirements of each project and should be considered by the decision makers to avoid the illogical decision making applied on the majority of civil projects and this imposes great financial and spiritual costs on our country. The present study attempts to present one of the civil projects (Ghasre Shirin storage dam) whose client was not ministry of energy for the first time and the short-term and long-term goals of the private sector were applied based on the triangle of quality, cost and time. Also, the math logic and model (multi-criteria decision making method and decision making matrix) is used in one of the most important sections of project, sealing element, policies and new materials (Geosynthetics) are considered and this leads to suitable decision making in this regard. It is worth to mention that this method is used for other sections of a dam including body, water diversion system, diaphragm and other sectors or in other civil projects of building, road construction, etc.
