This study was designed to investigate the elderly people's attitude toward death for the purpose of identifying the issues needed in the planning of health management and care activities for the aged. The total number of subjects in this study was 354 elderly people who were accommodated in house for elderly people (185) and school for elderly people (169). The scale for the attitude toward death of aged persons as an instrument of this study was mainly constructed with reference to Schneidman's attitude questioners toward death modified of adjust the Korean cultural characteristics and attitudes concerning death. Theresultsofthisstudywereasfollows: - 1. Out of total 45.8% of the respondents consider that death is a natural phenomena and ending of life. The responses on the meaning of death appeared differently : non-religions (48.1%) and oriental religions (50.3%) consider death as a natural phenomena however western religions (47.4%) consider that death is God's call. This difference was statistically significant. (x$^2$= 56.6419. df = 10. p<0.01). Respondents with a spouses (52.4%) think death is a natural phenomena opposed to respondent without spouses (33.3%). This was statistically significant. (x$^2$= 14.7134. df= 5 p<0.05). 2. Respondents in the house for aged persons (51.9%) replied. They do not wanted death because it meant a separation from their family as compared to those from school for aged persons (26.0%). 57.9% responded that they want to be told when death is confronted. 3. 51.2% of the respondents replied that the main factor to influence their attitude toward concept of death was the dying of their friends & relatives. 79.9% of respondents expressed that wished to die. The main reason for dying was economic shortage (28.3%). 4. 70.1% of the respondents want their body to be hurried while only 1.1% of the respondents want to donate their body to a medical research. 5. Over two thirds of the respondents replied that they do not believe in a life in heaven or that they will be rebirth. 6. The questioners of this study stimulated 56.8% of the respondents to feel that they should spend the leu of their life more effectively and 15.5% of the respondents felt it gave them the opportunity to think about their death seriously.

This study contributes to understanding women's labor market behavior by focusing on a particular set of labor force transitions - labor force withdrawal and entry during the period surrounding the first birth of a child. In particular, this study provides a dynamic analyses, using longitudinal data and event history analysis, to conceptualize labor force behaviors in a straightforward way. The main research question addresses which factors increase or decrease the hazard rates of leaving and entering the labor market. This study used piecewise Gompertz model, following the guide of the non-parametric analysis on the hazard rates, which allowed relatively detailed description on the distribution of timing of leave and entry to the labor market as parameters of interest. The results show that preferences and structural variables, as well as economic considerations, are very important factors to explain the labor market behavior of women in the period surrounding childbirth.

This study analyzed investment effects for Practical Field Studies conducted by the KOPIA (Korea Program on International Agriculture) centers, which are part of the ODA project operated by the Rural Development Administration. Focusing on the productivity and effectiveness factors of each project, a questionnaire survey was sent to each KOPIA center associated with each project. The results demonstrated the production and profitability of farms participating in the pilot project were significantly improved compared to those of farms that did not participate in the project. Also, in the satisfaction results of taste, nutrition, and freshness, the participating firms could significantly improve them when being compared to those of non-participating farms. It is highly expected to contribute to improving the operational effectiveness of Practical Field Projects conducted in Africa based on the results of each project's performance and economic feasibility. This study also can lead to a change in the social perception of ODA projects by raising people's awareness of ODA projects.

This study, which evaluated the contribution of the real economic value and system in the Nakdong River Basin, estimated the emergy analysis for environmental accounting of the TMDL program. And an environmental accounting for TMDL is evaluated before and after adopting TMDL program respectively. The value of emergy after adopting the TMDL was 7.90 E+20 sej/yr. Although the real yield of the river after governmental investment was high (before: 9.7118 E+20 sej/yr and after: 9.7224 E+20 sej/yr), the effects of improvement was not great, in terms of an investment cost. The benefit/cost ratio resulted from environmental accounting has decreased from 1.493 to 1.230 due to the cost of managing treatment facilities. The method of improving water quality in the Nakdong River Basin by the TMDL program should be changed into an ecological treatment facilities using resources efficiently from a control of water quality depending on expansion of the wastewater treatment facilities and advanced treatment plant using high cost and non-renewable energies.

Carbon dioxide has been known to be a typical greenhouse gas causing global warming, and a number of efforts have been proposed to reduce its concentration in the atmosphere. Among them, carbon dioxide capture and storage (CCS) has been taken into great account to accomplish the target reduction of carbon dioxide. In order to commercialize the CCS, its safety should be secured. In particular, if the stored carbon dioxide is leaked in the arable land, serious problems could come up in terms of crop growth. This study was conducted to investigate the effect of carbon dioxide leaked from storage sites on soil fertility. The leakage of carbon dioxide was simulated using the facility of its artificial injection into soils in the laboratory. Several soil chemical properties, such as pH, cation exchange capacity, electrical conductivity, the concentrations of exchangeable cations, nitrogen (N) (total-N, nitrate-N, and ammonia-N), phosphorus (P) (total-P and available-P), sulfur (S) (total-S and available-S), available-boron (B), and the contents of soil organic matter, were monitored as indicators of soil fertility during the period of artificial injection of carbon dioxide. Two kinds of soils, such as non-cultivated and cultivated soils, were compared in the artificial injection tests, and the latter included maize- and soybean-cultivated soils. The non-cultivated soil (NCS) was sandy soil of 42.6% porosity, the maize-cultivated soil (MCS) and soybean-cultivated soil (SCS) were loamy sand having 46.8% and 48.0% of porosities, respectively. The artificial injection facility had six columns: one was for the control without carbon dioxide injection, and the other five columns were used for the injections tests. Total injection periods for NCS and MCS/SCS were 60 and 70 days, respectively, and artificial rainfall events were simulated using one pore volume after the 12-day injection for the NCS and the 14-day injection for the MCS/SCS. After each rainfall event, the soil fertility indicators were measured for soil and leachate solution, and they were compared before and after the injection of carbon dioxide. The results indicate that the residual concentrations of exchangeable cations, total-N, total-P, the content of soil organic matter, and electrical conductivity were not likely to be affected by the injection of carbon dioxide. However, the residual concentrations of nitrate-N, ammonia-N, available-P, available-S, and available-B tended to decrease after the carbon dioxide injection, indicating that soil fertility might be reduced. Meanwhile, soil pH did not seem to be influenced due to the buffering capacity of soils, but it is speculated that a long-term leakage of carbon dioxide might bring about soil acidification.

This paper estimates relationships between the supply of national highways, measured in lane-km, and the quantity of traffic, measured in vehicle-km traveled. The analysis uses a panel data set of annual observations for the years 1984 to 2003. By using a log-linear lag effect model designed to capture short and long term effects, the paper estimates that national highway vehicle-km traveled has a lane-km elasticity of 0.268 at the country level (Non-Seoul Metropolitan area) and 0.41 at the Seoul metropolitan area for the short term. For the long term, the paper estimates 0.8 for the country level and 1.23 for the Seoul metropolitan area. This paper finds conclusive evidence that increases in highway lane-miles have generated traffic over the period of study, however the increasing ratio of the generated traffic decreases gradually, particularly during the late 1980s.

Korea-China FTA was initialized in 2015. Korea has a high level of dependence on trade for its economic growth, especially to China. Technical Barriers to Trade(TBT) among various non-tariff barriers is becoming increasingly important. Elimination of TBT is one of the key issues in which the South Korean government is interested since technical barriers significantly affect trade between the two countries. MRA has been considered as an effective tool to relieve such technical barriers. Several studies and surveys showed that MRA would mitigate the barriers of import and solve the problems that many companies face in international market. This study tries to seek utilization plan of MRA for Korea-China FTA. It suggests suitable utilization plan of MRA considering the difference of technical regulations between two countries. This paper has value in that it provides specific MRA strategies targeting China while other prior studies have merely analyzed the necessity of MRA.

This study is to investigate causal relationship between individual life satisfaction and air pollution, using ordered probit model with the KLIPS panel dataset for 1998-2008. As determinants, both individual economic and socio-demographic characteristics are considered. Empirical results show that the degree of air pollution has negative effects on individual life satisfaction. The effects of other variables are similar to those of existing studies. This study found that life satisfaction increases along with income increase. However, at a certain point, the increase of life satisfaction becomes smaller even with an increase in income, indicating non-linear effect. It implies that the Easterlin's paradox can be applied to Korea's case. The increase of the other person's income measured by income per capita in the region where respondent resides has negative effects on life satisfaction. On the other hand, a person who has married, own house, stayed healthy, and highly been educated is likely to have higher life satisfaction. Additionally, a person with many household members, urban resident, unemployed or self-employed are negatively correlated with life satisfaction.

In Korea, there are 1,474 thousand pumping wells nationwide which account for about 12% of total water use in 2012. As much as 39 hundred million tons of groundwater were used while 333 hundred million tons of total water were supplied in 2012. Because the water management authority projects that water demand will exceed supply by 2021, the authority is planning to extensively expand groundwater use in accordance with economic feasibility. Using the basic frameworks of cost-benefit analyses of the World Bank and the US Environmental Protection Agency (US EPA), the objective of this study is to examine the costs and benefits of the expansion of Korea's groundwater extraction through pumping wells. We conclude that the BC ratio of the groundwater pumping wells is 2.98. This signifies that the benefits are 2.98 times higher than the costs. The benefits include use and non-use values of pumping wells while the costs include the installation and maintenance of new wells, in addition to the restoration and pollution costs of abandoned wells, as well as fees for water quality tests, etc.

Background : Economic evaluation of clinical pharmacokinetic consultation services for theophylline, which is being widely used recently, is considered in patients for both proper care and cost efficiency. Mathods : This is a cost-benefit analysis of clinical pharmacokinetic consultation service for theophylline. Trial groups were chosen from 2 general hospitals which was performing clinical pharmacokinetic consultation- services in 1998. Control group was chosen from another one general hospital. The analysis includes 25 patients (sample patients) for trial group and 17 patients for control group. Results : On the basis of incremental analysis, it is estimated that the total (direct and indirect) annual costs of the clinical, pharmacokinetic services of theophylline for the patients in the trial group was about \65 million, whereas total annual benefits from those services was estimated to be about \551 million. The net benefits incurred to the sample patients, thus calculated, was about \485 million per year. In the analysis, we assumed that indirect benefits accruing to those services were non-existent. If that amount was included, the estimated net benefits would be much greater than the calculated one. Conclusion : We found that clinical pharmacokinetic consultation services for theophylline could produce more marginal benefits than marginal costs by those services from the social point of view. More controlled prospective trial in the future would be helpful for affirmation of the results of this study.
