The cost of the construction and management of new apartment buildings was evaluated using a monetary analysis and an emergy concept to provide a new perspective regarding the housing policy of Korea. The systems of analyses were typical apartment buildings with an area of $76.03m^2$ per household in Korea built on the same size of land area. Three apartment buildings with different stories were evaluated and compared; 5-story, 15-story, and 20-story apartment buildings. The durable years of those apartments were assumed to be 40 years. The total cost of the construction and management of an apartment building was divided into three categories of construction, land purchase, and management. A 20-story apartment showed the highest cost and a 15-story apartment the lowest in the monetary cost analysis. In contrast, the emergy evaluation revealed a different pattern in the cost of construction and management, the cost increasing from a 5-story apartment to a 20-story one. This means that the higher the apartment constructed, the greater the cost in terms of real wealth. This result suggests that new evaluation methodologies like the emergy analysis should be used together with the monetary analysis to provide better insights on the national housing policy.

The specific purpose of this study is to develop the numerical guide for the cost-benefit analysis of ORE ($/person-Sv reduction) to meet the criterion of ALARA in the design stage of the KNGR. In deriving the guide, the risk factor which is defined by the risk to unit collective radiation exposure dose (deaths/person-Sv) and the monetary value of human life ($/death) are required. The risk factor has been estimated from various clinical data accumulated for a number of years and continuously modified. And the monetary value of human life is usually quantified using the human capital approach. In this study, the risk to radiation exposure perceived by a group of people is investigated through an extensive poll survey conducted among university students in order to modify the existing risk factor for radiation exposure. And in evaluating the monetary value of human life, the QOL factor is introduced in order to incorporate the degree of public welfare or quality of life. As a result of study, a value within the range of 151, 000~172, 000 dollars per person-Sv reduction is recommended as the appropriate interim numerical guide for cost-benefit analysis of ORE to meet the criterion of ALARA in the design stage of the KNGR. A poll survey was also conducted in order to see whether the public acceptance cost of nuclear power should be incorporated in developing the guide, and the result of study shooed that such a cost does not need to be considered.

The conflicts between environment protection and economic development are becoming increasingly important in environmental decision making of Nakdong River Basin. A science-based evaluation system is now needed to represent both the environmental values and the economic values with a common measure. EMERGY, spelled with an \"m\" evaluates both the work of river and that of human in generating products and services. The monetary cost-benefit analysis and the environmental accounting by EMERGY analysis were applied to determine whether there will have a net benefit in environmental decision making of Nakdong River Basin. Based on the results of the environmental accounting, all alternatives which related to environmental decision making of Nakdong River Basin show that more and more of EMERGY cost becomes needed than the a EMERGY benefit from getting water to drink in the lower basin. From these results, for selecting alternatives to manage water quantity and quality that is sustainable in the environmental use and economic development, environmental accounting concepts must be considered, and the economic structure of Nakdong River Basin should be changed from the present industrial structure to social-economic based on ecological-recycling concept for the sustainable use of Nakdong River.ong River.

Unlike typical corporate investments, IT expenditures have direct impact on many aspects of a business, including those that are difficult to quantify. Therefore, financial indicators alone do not do justice to the full effect of an If investment. Proposed in this paper is a methodology to measure the return on IT investments, including non-financial impacts expressed in terms of monetary values. This methodology shows tangible cost as well as hidden cost by analyzing total cost of ownership. The methodology also produces ROI by performing cost benefit analysis including financial and non-financial factors. This paper suggests a more objective validation of If's impact on the business activities. It rationalizes investment priorities and provides a systematic approach to effective IT investment.

the purpose of this study was to compare the consumption of personal and material resources between working wives and full-time housewives and to conceptualize the cost of working wives by the degree of additional consumption of the resources. The proposed costs of working wives included the long working time (time cost), the short leisure time(energy cost), the increase of expenditures fro services and the serious role conflict(psychological cost). Three methods, t-test, simple regression analysis, multiple regression analysis/tobit analysis were used to analyse the differences in consumption of resources between two groups. On the basis of the analysed results, the employment cost of working wives were discussed.

This study analyzed the managerial efficiency of 11 organizations, the branch centers of a occupational health service organization in Korea, using the Data Envelopment Analysis (DEA) method. The DEA is a good method for evaluating health services since it can handle multiple inputs and outputs simultaneously, and also identify the sources and amount of inefficiency. The author approached this study using two efficient models: the monetary value model and the real value model. The DEA method based on the monetary value model included cost factors, while the real value model excluded cost factors. The input variables used were manpower of physicians, medical technicians, nurses, industrial hygienists and administrators; labor, maintenance, and material expenses. The output variables used were the number of medical examinations, workplace evaluations, group health management services and income from each service. The major results were as follows: First, in the monetary value model, 6 out of 11 organizations (54.6%) showed an efficiency score of 1.0, which means that they have been operating in very efficient ways. However, 5 organizations (46.4%) showed themselves to be relatively inefficient. Second, in the real value model, 7 out of 11 organizations (63.4%) showed an efficiency score of 1.0, which means they have been operating efficiently, while 4 organizations (46.4%) showed themselves to be relatively inefficient. Third, the reliability of DEA method were analyzed by comparing the results of the monetary value model and real value model. The results of 8 out of 11 organizations were same in terms of being efficient or not. Thus, the DEA could be a valid application method for occupational health service organizations. Fourth, the organizations that displayed common inefficiency in both the monetary value model and in the real value model 3, 9, and 10, were also considered to be managed inefficiency from expertise opinion. In summary, this study evaluated the efficiency of occupational health service organizations applying the DEA method with different variables, and found that the results of analysis could be valid in terms of both modeling and expert sense. In the future, the DEA method will be used as a useful tool to identify and evaluate the efficiency of occupational health service organizations through more applications and refinements.

This paper examines monetary policy quantitatively in a two-agent and small-scale New-Keynesian economy with debt-constrained households that cannot smooth their consumption intertemporally and frictionlessly since highly indebted households are not allowed to borrow above a certain debt ceiling in incomplete financial markets without additional risk premiums due to information asymmetry between savers and borrowers. We find that, in the event of cost shocks, the asymmetric responses of borrowing households without, and saving households with, dividend incomes lead to different labor supplies and consumptions over heterogeneous households, and eventually to an extension of the monetary policy transmission channels. The income effect and low elasticity of the labor supply play key roles in such asymmetric responses over heterogeneous households. We also find that the social welfare in a flexible inflation targeting (FIT) monetary policy, in which both the inflation gap and the output gap are considered in an integrated manner when policy-making, is similar to that of the Ramsey optimal monetary policy (ROP), in which the shares of debt-constrained households, as well as all economic states, including both the inflation gap and output gap, are considered comprehensively for policy-making, and that it is greater than that of simple inflation targeting (SIT) monetary policy, in which only the inflation gap is considered mechanically for policy-making. Such social welfare implies that a FIT policy may still work even in an economy with a sizable number of debt-constrained households. Further, the responses of cost shocks to consumption and labor supply are dying out more slowly under FIT and ROP policies than under an SIT policy.

The environmental problem come because the demage cost of environmental pollution is not properly reflected in market price. The government regulations for market is justified to solve the problem. The policy needs a close analysis of environmental, economical effect for the point of time, methods, rational decision making of the government regulations. Especially, we need to assume and analyze about social expenses by environmental pollution and policy execution. The cost-benefit analysis about environmental pollution is used to support decision making. The value of benefit about damage by environmental pollution or about improvement changes a monetary unit through the cost-benefit analysis. The working like this is said environmental material valuation or measuring valuation. This work is studied about looking for proper analysis model to apply our environmental materials.

Project cost is an important concern in any construction project. Although there has been a lot of studies on factors affecting the cost of construction projects, there seems no consensus as what cost factors have direct influence on the cost of civil engineering projects. This study therefore aims to bridge the current knowledge gap by examining quantity surveyors' perception of the factor structure among nineteen costing attributes identified based on literature review. Questionnaire was used to elicit responses from quantity surveyors working in the Hong Kong construction industry. Principal component analysis is conducted to extract the factor structure of the cost attributes and the attributes are grouped into three factor components, namely the contract management factor, the project management factor and the monetary value factor. Understanding these cost impact factors could be crucial in managing civil engineering projects, since it allows the project stakeholders and quantity surveyors to take precautionary steps to identify the cost management problems and areas for improvement and could even help to avoid cost deviations in engineering projects.

This research is a qualitative based study by using data gleaned from documentary analysis and in-depth interviews of 10 potential stakeholders were involved in the proposed high-speed train project in Thailand. Many perspectives from key informants revealed that this project would bring Thailand sustainable development in the future due to the fact that it is supposed to be an environmentally friendly mode of transportation and timesaving for passengers. Key informants who tend to have negative opinions towards the project feel apprehension due to the huge monetary investment during a time of monetary crisis. However, there was one complaint that the high-speed train is harmful to the environment surrounding the proposed area of this project. Several key informants agreed that ticket fares must be in between the cost of a bus ticket and airfare.
