Objectives: To protect the health and safety of residents during chemical accidents, the governmental authorities need to provide personal protective equipment (PPE) to citizens who desire it. This study aims to investigate residents'awareness of PPE and perform an economic analysis on providing PPE to residents near chemical plants prior to the establishment of a related law. Methods: This study was carried out through a questionnaire completed by 600 residents composed of items such as residents'awareness of PPE, what type of PPE they need, and how to purchase PPE. Economic analysis (cost-benefit analysis) was conducted on providing PPE to residents near chemical plants on basis of the Gumi City hydrogen fluoride accident of 2012. Results: The results of the questionnaire showed that most residents recognized the need for PPE preparedness for chemical accidents, in particular, for respirators. The level of expense that respondents were prepared to shoulder to share the burden was $25. Except for chemicals of hazard level 2, the benefit of all kinds of chemical accident preparedness considerably exceeded costs in the cost-benefit analysis on providing PPE. An estimated government budget of $20 million per year would be required to provide PPE (hood-type mask) for all residents within a one-kilometer radius of chemical plants in Korea, but only $5.8 million when residents share the expenses. Conclusion: The results of this study suggest that programs for providing PPE for residents near chemical plants should be established by law.

Background: As of July 2015, per diem payment was changed from fee for service Therefore, this study aims to analyse changes in medical charges and medical services before and after enforcement of the palliative care, targeting palliative care wards in a general hospital, and provide basic data needed for development of per diem payment. Methods: The subjects of the study were a total of 610 cases consisting of 351 patients of service fee who left hospital (died) from July 2014 to June 2016 and 259 ones of per diem payment at Chosun University Hospital in Gwangju Metropolitan City. Results: The results are summarized as follows. First, after the palliative care system was applied, benefit medical service charges and insurance increased significantly (p<0.001). As benefit medical service charges increased, benefit private insurance payment increased significantly (p<0.001). Second, after the per diem payment was applied, total private insurance payment to medical institutes decreased significantly (p=0.050) and non-benefit also decreased significantly (p=0.001). Conclusion: It is suggested that additional rewards in the obligatory palliative care items should be continuously remedied and monitored to provide good quality hospice palliative care.

The purpose of this study is to elaborate the logical configuration of livelihood benefits for the institutionalized recipients under the renewed custom-tailored benefit system of National Basic Livelihood Security System(NBLSS) and to present appropriate level of benefits in terms of coherency of the system. In July 2015, the NBLSS was reformed to adopt a relative level of benefit standard for the general recipients according to certain amount of ratio of standard median income. However, the benefit for the institutionalized recipients was still based on the cost of necessities of absolute poverty level. It is at this juncture that this study suggests livelihood benefits for the institutionalized recipients reflect standard median income to comply with the reform of the NBLSS. To this end, this study firstly derives basic living items for the institutionalized recipients based on the literature review and FGI. Secondly, it calculates the reflection ratio of livelihood benefits utilizing Household Trend Survey's consumption data under 40%. Finally, it applies equivalence scale of households to adjust the under-represented scale for large size institutions. To continue the reflection ratio method, it is necessary to review the consumption trends and the stability of the reflection ratio periodically.

This study was carried out to quantify degree of contribution of harvested wood product (HWP) on mitigation of climate change by valuation of public benefits, environmentally and economically. The potential carbon dioxide emission reduction of HWP was estimated by accounting carbon storage effect and substitution effect. Based on 2014 statistics of Korea Forest Service, domestic HWPs were sorted by two categories, such as wood products produced domestically from domestic and imported roundwood. The wood products were divided into seven items; sawnwood, plywood, particle board, fiberboard (MDF), paper (including pulp), biomass (wood pellet) and other products. The carbon stock of wood products and substitution effects during manufacturing process was evaluated by items. Based on the relevant carbon emission factor and life cycle analysis, the amount of carbon dioxide emission per unit volume on HWP was quantified. The amounts of carbon stock of HWP produced from domestic and from imported roundwood were 3.8 million $tCO_{2eq}$., and 2.6 million $tCO_{2eq}$., respectively. Also, each reduction of carbon emission by substitution effect of HWP produced from domestic and imported roundwood was 3.1 million $tCO_{2eq}$. and 2.1 million $tCO_{2eq}$., respectively. The results of this study, the amount of carbon emission reduction of HWP, can be effectively used as a basic data for promotion of wood utilization to revise and establish new wood utilization promotion policy such as 'forest carbon offset scheme', and 'carbon storage labeling system of HWP'.

Objectives: This study was to examined the level of psychosocial factors, dietary habits and DMFT index and to examined the relationship among variables in 12-year-old adolescents. Methods: Participants were 1,831 total students from 14 middle school who lived Seosan with mean age of 12.46 years. Data was collected using a self administrated questionnaire from April 13 to May 24, 2009. Psychosocial factors and dietary habits were measured using the 5-items and 10-items. A trained investigator made an oral examination of them in natural light using a mirror and explorer to determine their DMFT index. Data were analyzed with t-test, one-way ANOVA, and Tukey test, pearson correlation coefficient using the SPSS WIN 15.0 program. Results: Regarding dietary self-efficacy, perceived benefit and perceived barrier degree, the subjects achieved a mean of $3.89{\pm}0.69$, $3.48{\pm}0.63$ and $3.82{\pm}0.63$ out of a maximum 5 points. And the dietary habit degree of subjects achieved a mean of $10.69{\pm}4.02$ out of a maximum 20 points and the DMFT index were $1.91{\pm}2.26$. Dietary habits was positively correlated with psychosocial factors and negatively correlated with DMFT index. And then perceived barrier score were negatively correlated with DMFT index. Conclusion: Based on the findings, dental caries experience is associated with perceived barrier and dietary habits. These results suggest that the implementation of health promotion should be considered for various psychosocial factors and dietary habits in adolescents.

The master plan for the Four Rivers Restoration Project (June 2009) was devised, the procedure of pre-environmental review (June 2009) and environmental impact assessment (Nov. 2009), and post-environmental impact survey were implemented, and 4 times audits also inspected. and finally the Ministry of Environment's Four Rivers Investigation and Evaluation Planning Committee proposed the dismantling or partial dismantling of the five weirs of the Geum River and Yeongsan River. But controversies and conflicts are still ongoing. Therefore, this study intend to reestablish the management plan for the four major rivers by reviewing and analyzing the process so far. The results are as follows. First, a cost-benefit analysis should be performed by comparing the water quality impact of weir operation and weir opening. Therefore, it is inevitably difficult to conduct cost-benefit analysis. Second, according to the results of cost-benefit analysis on the dismantling of the Geum River and the Yeongsan River, the dismantling of the weir and the regular sluice gate opening was decided. However, there is a problem in the validity of the decision to dismantle the weir because the cost-benefit analysis for maintaining the weir is not carried out. Third, looking at the change in water quality of 16 weirs before and after the Four Major Rivers Restoration Project, COD and Chl-a were generally deteriorated, and BOD, SS, T-N, and T-P improved. However, in the cost-benefit analysis related to water quality at the time of weir dismantling, only COD items were targeted. Therefore, the cost of BOD, SS, T-N, and T-P items improved after the project were not reflected in the cost-benefit analysis of dismantling weirs, so the water quality benefits were exaggerated. Fourth, in the case of Gongju weir and Juksan weir, most of them are movable weirs, so opening the weir alone can have the same effect as dismantling when the water quality deteriorates. Since the same effect can be expected, there is little need to dismantle the weirs. Fifth, in order to respond to frequent droughts and floods, it is desirable to secure the agricultural water supply capacity to the drought areas upstream of the four majorrivers by constructing a waterway connected to the weir. At present it is necessary to keep weirs rather than dismantling them.

Recently, technology for energy recovery from waste has been increasing interest globally including the Korea. In Korea, we have interested in using biogas generated from the sewage treatment process. As one alternative, there are operating biogas combined heat and power plant. The generation amount of the Sewage Sludge are expected to grow in the future. For this reason, total processing cost of Sewage Sludge will increase. To solve this problem, it seems will be invested with the expansion of facilities that use biogas as energy. Therefore, quantitative information on such facilities is required. Thus, this study attempts to economic feasibility analysis for Seonam Biogas Combined Heat and Power Plant. Meanwhile, as the benefit items for economic feasibility analysis consider electricity supply benefit except for heat supply benefit. The average prices of electricity use were residence 123.69, commercial 130.46, and industry 102.59 won per kWh for the year 2015, In addition, the economic benefit are calculated to be residence 310.21, commercial 378.49, and industry 222.87 won per kWh. The results of economic feasibility analysis is NPV 72.18 billion won, B/C 1.90, IRR 37%, shows that economic validity of Seonam Biogas Combined Heat and Power Plant.

The purpose of this study was to identify factors influencing patient satisfaction and to evaluate the utility of patient satisfaction as an outcome indicator. The study was conducted by mailed questionnaire. The subjects were 900 patients discharged from adult nursing units in a tertiary teaching hospital. On the discharge date, questionnaires were distributed by two trained research assistants. The questionnaire developed by the researchers was based on Larson(1996)'s study, and consisted of 71 items with the following components: overall satisfaction, domain-specific satisfaction(administration process, hospital facility and environment, nurses, and doctors), patients' loyalty(intention to use the health care service of the hospital in the future), recommendation to others, health benefits, and demographic characteristics. Each item was rated using a five point Likert scale ranging from '1=strongly disagree' to '5= strongly agree'. The response rate was 43%(387/900). The satisfaction level with the health care service was generally high. Perceived health status was the only significant factor influencing satisfaction level. Satisfaction with doctors contributed the most to explaining overall satisfaction. Overall satisfaction was significantly correlated with patient loyalty, recommendation, to other and perceived health benefit. It was found that the score of satisfaction was positively correlated with the score of loyalty, recommendation, and health benefit. Therefore, patient satisfaction seems to be a good outcome indicator.
