  • The purpose of this study is to find the differences between the husband's and wife's satisfaction of home life. This study is also to compare and analyze some empirical influence on life satisfaction of husband and wife according to home socio-demographic variables and subjective evaluation of economic level including their perception levels of home economics circumstance. The major results are as follows; 1. The husband's score of life satisfaction shows signifcantly more than wife's score that is his score is 3.36 and her score is 3.19. 2. The variables which affect couple's life satisfaction are the perception of resource adequacy the perception of the adequacy of household income, the evaluation level of resource contribution and the perception of level of living relative to others. The most influential variable of the husband is the perception of resource adequacy, while the most influential variable of the sife is the evaluation level of resource contribution. 3. The result of the relative contribution for the variables of life satisfaction are as follows. The explanation of husband's sociodemographic variable is 11.5% if variable of subjective evaluation of economic level is added the explain power is 34.1%(increase, 22.6% (p<0.001)) The explanation of wife's socio-demographic variable is 9.8% If variable of subjective evaluation of economic level is added the explanation is 41.2% (increase 31.4% (p<0.001)).

  • This paper deals with an economic evaluation of domestic low-temperature water electrolysis hydrogen production. We evaluate the economic feasibility of on-site hydrogen fueling stations with the hydrogen production capacity of 30 $Nm^3/hr$ by the alkaline and the polymer electrolyte membrane water electrolysis. The hydrogen production prices of the alkaline water electrolysis, the polymer electrolyte membrane water electrolysis, and the steam methane reforming hydrogen fueling stations with the hydrogen production capacity of 30 $Nm^3/hr$ were estimated as 18,403 $won/kgH_2$, 22,945 $won/kgH_2$, 21,412 $won/kgH_2$, respectively. Domestic alkaline water electrolysis hydrogen production is evaluated as economical for small on-site hydrogen fueling stations, and we need to further study the economic evaluation of low-temperature water electrolysis hydrogen production for medium and large scale on-site hydrogen fueling stations.

  • It has become very important for unused energy to be used for building air conditioning. Economic evaluation on energy system by using river water as a heat source, which is one of the unused energy, was carried out. The floor area of the building and the distance between heat source equipment and river was assumed $50,000m^2$ and 200 m. General heat source system using absorption chiller-heater was used for comparing to the energy saving system, and payback period method using initial cost and running cost of two systems, was used to perform economic evaluation. According to development of high capacity of water source heat pump which is appropriate for using river water, initial cost for the system has been reduced. Payback period was about 3.2 years, and this period might be shortened if nation's economic support enact.

  • There has been a need for the systematic evaluation of the economic efficiency between conventional fluorescent lamp lighting systems that have been used in tunnels and LED lighting systems. This study has evaluated basic tunnel lighting between the conventional fluorescent lighting systems and the LED lighting system using the evaluation tool of tunnel lighting by Life Cycle Cost (LCC) and using the economic efficiency evaluation method. In addition, the unit discount rate of the LED lighting system and the estimated increase in the price of electricity have made the estimated cost of LCC the same if two luminaires were used in the basic part of the tunnel.

  • Economic Development Zone(EDZ) in the province is one of the foreign policy for economic development of North Korea. North Korea has promulgated 27 Economic Development Zones(5 EDZs as central level and 22 EDZs as provincial level) to promote economic growth through the expansion of external opening policy. EDZs of the provinces play an important role in North Korea's national and regional economic growth. The purpose of this study is to select analytical criteria that can be quantified when considering the location conditions of North Korean economic development zones when domestic companies advance into North Korea according to the progress of inter-Korean economic cooperation, and derive the relative importance between the criteria. After that, based on this, we intend to quantify the evaluation of the location priority of the economic development zone. In this study, through AHP analysis results, when domestic companies enter North Korea, we derive the importance and preference of location selection factors when considering the location conditions of North Korean economic development zones. Taking into account the reality of North Korea when the Korean company entered the North economic development zone following location for evaluation. That is, logistics and transportation, industrial infrastructure, competitiveness, and management incentives. And 14 sub-factors were selected and AHP analysis was performed.

  • Objectives: There is no systematic review on economic evaluations of telemedicine in Japan, despite over 1000 trials implemented. Our systematic review aims to examine whether Japan's telemedicine is cost-saving or cost-effective, examine the methodological rigorousness of the economic evaluations, and discuss future studies needed to improve telemedicine's financial sustainability. Methods: We searched five databases, including two Japanese databases, to find peer-reviewed articles published between January 1, 2000 and December 31, 2014 in English and Japanese that performed economic evaluations of Japan's telemedicine programs. The methodological rigorousness of the economic analyses was assessed with a well-established checklist. We calculated the benefit-to-cost ratio (BCR) when a reviewed study reported related data but did not report the BCR. All cost values were adjusted to 2014 US dollars. Results: Among the 17 articles identified, six studies reported on settings connecting physicians for specialist consultations, and eleven studies on settings connecting healthcare providers and patients at home. There are three cost-benefit analyses and three cost-minimization analyses. The remaining studies measured the benefit of telemedicine only, using medical expenditure saved or users' willingness-to-pay. There was substantial diversity in the methodological rigorousness. Studies on teledermatology and teleradiology indicated a favorable level of economic efficiency. Studies on telehomecare gave mixed results. One cost-benefit analysis on telehomecare indicated a low economic efficiency, partly due to public subsidy rules, e.g., a too short budget period. Conclusions: Overall, telemedicine programs in Japan were indicated to have a favorable level of economic efficiency. However, the scarcity of the economic literature indicates the need for further rigorous economic evaluation studies.

  • The purpose of this study is to develope the model of economy analysis and evaluation to justify the effect of economic feasibility for constructing ERP system in the company. Since the results for the evaluation of alternatives are influenced by the nature of capital and the circumstances, it is very difficult to evaluate the alternatives and it takes too much time to apply it in the field on account of many alternatives. This study suggests establishment and application of the model on economic analysis and evaluation regarding the nature of capital by using excel spread sheets.

  • Sustainable development has been the key concept, both in economic policies and in environmental management. On the basis of an systems ecology perspective, this suggests the sustainable development of Korea\`s natural environment and economic activity using the EMERGY evaluation. The total EMERGY use(7,730E20sej/yr) in Korea is 81 percent from imported sources, fuels and goods and services. The ratio of outside investment to attracting natural resources is already large, like other industrialized countries. Continued availability of purchased inputs at a favorable balance of EMERGY trade, currently about 2.85 to 1 net EMERGY, tis the basis for present economic activity and must decrease as the net EMERGY of purchased inputs including fossil fuels goes down. EMERGY yield ratio and environmental loading ratio were 1.23 and 20.30, respectively. The population level is already in excess of carrying capacity. Its carrying capacity for steady state on its renewable sources is only 2.2 million people, compared to 45.9 million in 1977. EMERGY sustainability index is therefore less than one, which is indicative of highly developed consumer oriented economies. Until now the development of a country has been achieved by the economic growth, but it can be sustained in the long run by the use of renewable resource systems. the efficiency of energy usage, and the transformation of the social-economic structure based on an ecological-recycling concept.
