Unlike other disasters, the water shortage problem caused by drought is characterized by the long-lasting ripple effect of the social and economic sectors in all regions of Korea, and the types and purposes of water mainly used are different depending on the type of region, so the factors and scale of water shortage damage are different. In this study, a methodology to evaluate the risk of water shortage based on socioeconomic characteristics was developed and applied to Gwangju and Jeollanam-do to analyze the results. To this end, 20 impact indicators for risk, exposure, and vulnerability items were selected according to the climate risk concept of IPCC AR6. The results of the water shortage risk evaluation reflecting socioeconomic characteristics were different from the risk results considering only the existing meteorological and hydrological factors. The areas with the greatest risk of water shortage were calculated as Yeonggwang-eup in Yeonggwang-gun, Yeonsan-dong and Haean-dong 4-ga in Mokpo-si, Jeokryang-dong in Yeosu-si and Geumsan-myeon in Goheung-si. Through the evaluation results, risk factors and countermeasures for water shortage were derived in consideration of detailed characteristics of the region, which can be used as data contributing to the establishment of measures to reduce drought damage tailored to the region in the future.

This study is intended to figure out determinants affecting the economic preparations for old age of pastors from major four protestant associations having a church ministerial pension system: the General Assembly of Presbyterian Church in Korea (GAPCK), the Presbyterian Church of Korea (PCK), the Presbyterian Church in the Republic of Korea (PROK), and the Korean Methodist Church (KMC). Thereby, it conducted a survey to 452 pastors from the four religious associations in Korea. The followings sum up the results of this research. First, it was shown that the conventional idea that there is no need for pastors to prepare for their old age or their preparations for old age imply disbelief had been diminished. Second, there were few pastors who had made economic preparations for their old age privately. Third, associations adopting a compulsory church ministerial pension system were PCK, PROK, and KMC indicating a high occupation of more than 75% whereas GAPCK with an optional system showed a very low percentage of 11.5%. Fourth, with regard to the national pension system, the associations except for PROK (61.8%) had more non-enrolled pastors (53.3%), and they responded economic difficulty as the biggest reason for the unenrollment. Fourth, determinants affecting their economic preparations for old age were academic career, total income, church independency, church reserving, and national pension enrollment. Fifth, among the pastors from the four associations, the ones of PROK prepared for their old age best in consideration of GAPCK. According to the results of this paper, the most critical determinant affecting pastors' economic preparations for old age was total income. Pastors with higher income can make church ministerial pension, national pension, and private preparations while the ones with lower income cannot afford for public as well as private preparations; that is, there exists a polarization phenomenon in pastors' economic preparations for old age. Therefore, it is necessary to make devices to narrow the income gap between pastors in religious associations. Second, even in the associations having a compulsory church ministerial pension system, many pastors were not insured, so it is needed to reform or improve the pension system. Third, it is also required to better the national pension system and change the recognition on it.

The purpose of this study was to suggest indicator-based selection and improvement plans for evaluating urban regeneration projects. First, we selected the indicators by conducting expert surveys and analysis of the responses received. Additionally, using the selected indicators, we analyzed the residents' opinions in Wongogae Village, where urban regeneration projects were in progress. Based on these, we suggested a plan to improve Wongogae Village. According to the study, we classified the urban regeneration evaluation indicators into 'Physical environment', 'Social environment' and 'Economic environment' according to their characteristics. We selected urban regeneration evaluation factors through the first expert survey and MCB analysis. As a result, we selected six factors for the 'Physical environment' category: 'Traffic and pedestrian environment', 'Residential (housing) environment', 'Safety and security environment', 'Greenspace', 'Landscape improvement' and 'Public space', In the 'Social environment' category, four factors were chosen: 'Resident participation', 'Community activation', 'Role of the local government and support centers' and 'Resident education' while for the 'Economic environment' category three factors were selected: 'Local economic revitalization', 'Creating an economy-based environment', 'Job creation'. Next, we conducted a second expert survey and carried out an AHP analysis using the selected evaluation factors to derive the overall weight for each. Among the evaluation factors for urban regeneration, the 'Residential (housing) environment' has the highest weighted value of 0.108, followed by 'Local economic revitalization' and 'Resident participation'. Lastly, the analysis of the residents' opinions of Wongogae Village using the urban regeneration evaluation factors, Parking environment', 'Maintenance of old houses and living environment', 'Environment for founding town and social enterprises', 'Improve commercial and business environment', 'Maintain and activate existing business' and 'Vitalizing small regional economies such as domestic handicrafts and side-job' had high overall importance, but low satisfaction, which means that it is necessary to improve the focus. Therefore, in order to improve the urban regeneration project in villages, it is necessary to improve the parking environment by expanding public parking lots, eliminate close houses, and idle lands, or open a school playground in the village for the residents. In addition, it is essential to encourage economic activities, such as fostering village enterprises and social enterprises in connection with cooperatives and allow for the selling of the products through resident activities, such as neighboring markets.

Purpose: The influence of the hoping number of children, the policy of childbirth, and the causes of reduced childbirth to the perception of childbirth, which will be the subject of future childbirth, was surveyed by health-line college students. Results: In terms of the attitude to the perception of childbirth, the quality of personal life, childcare, insufficient support of childbirth, and breeding of descendants had the largest influence on childbirth, and in terms of the attitude to the hoping number of children, economic reasons, childcare expenses, and education expenses had the largest influences. Second, when the causes of social demographic properties influencing childbirth was analyzed, sex showed significance to all the factors on the hoping number of children in terms of growing areas, to all the factors excluding childbirth policy in terms of the economic level, and hoping number of children in terms of the parents' jobs. Third, when the correlation was analyzed, a correlation was found in every area excluding the hoping number of children in terms of the causes of childbirth reduction and economy, childbirth policy in terms of the personal causes, personal factor in terms of the causes of childbirth policy, and family factor in terms of the causes of childbirth reduction and economy. Fourth, when the influences of the causes of hoping number of children, childbirth policy, and childbirth reduction to perception of childbirth were analyzed, the case hoping no or one child, the case hoping 2 or more children, childbirth policy, and childbirth reduction had a positive significant influence on the perception of childbirth. Conclusion: The childbirth rate will be improved if the following occur: childbirth policy and laws are established at the level of government, education programs are developed and operated for the formation of the value of perception of childbirth, and a new support policy is established after analyzing the current childbirth support policies. To change the perception of childbirth in college students who are future subjects of childbirth, successive studies will be needed to verify the effect of aforesaid measures.

Government-funded research institutes in the field of science and technology of Korea have contributed to the growth of the national economy and industrial development since the 1960s. However, those institutes recently have faced with criticism over the R&D performance on investment. Accordingly, we suggest two analytical approaches that estimate the economic benefit of the R&D performance of those institutes, (1) 'bottom-up' approach that aggregates the economic benefits of individual performances, e.g., technology transfer, technology support for small and medium enterprises, and the supply of researcher manpower and (2) 'top-down' one that estimates the contribution of those institutes on the economic growth of the industries that the R&D performance of those institutes is mainly utilized. In addition, by applying two approaches, we computed the economic benefit of the performance of the K institute in the 1996-2014 periods at 12.3 trillion won and 29.5 trillion won, respectively. Lastly, we suggest the feasibility of two approaches from the perspective of complementarity. Our study provides analytical approaches that estimate the economic benefit of the R&D performance from government funded research institutes in Korea. Lastly, our study contributes to the understanding of public on science and technology as well as the enhancement of legitimacy on those institutes among the public.

Solutions for elderly health issues need to be found that take into account not only a medical perspective, but also interactions with social conditions such as socioeconomic status. With this in mind, this study aims to understand how socioeconomic status leads to health inequalities for the elderly. Specifically, this study investigates the mediating effects of socioeconomic status(income and education levels), health activities as an intermediary of the three dimensions of physical health(medical health, functional health, subjective health), accessibility of medical facilities, social participation, and social network. To test the research model, a secondary data analysis was conducted on the 2014 National Survey of Senior Citizens. The participants of the study were 10,451 elderly men and women aged 65 and above. To test the mediated model, hierarchical multiple regression analysis was conducted following the procedures suggested by Baron and Kenny(1986). In addition, a Sobel test was conducted to test the mediated model's significance. According to the analysis, the effects of income and educational levels on the health of the elderly were not the same. Additionally, different results were found depending on health dimensions. However, the overall direction of the results showed that the socioeconomic status of the elderly creates health disparities, and health behaviors, accessibility of medical facilities, social participation, and social network had significant mediation effects between socioeconomic status and physical health. Study findings especially worth noting are as follows: education was shown to have a stronger effect on health than income; effects of social integration factors such as social participation were highlighted; and significant mediating effects on the accessibility of medical facilities remained even after taking residential area into account. Results of this study shed light on health inequality mechanisms due to socioeconomic conditions and the need to find alternatives to alleviate these problems.

The purpose of this study is to investigate the relationships between socio-economic position(SEP), environmental exposures, and health of older people in Korea. This study used the data from 'Environmental Exposures and Their Health Effect in Korean Elderly Population'. The sample includes a total of 563 elderly people who were 60 years of age or older. Data on SEP, environmental exposure, and health impact were collected and analyzed using descriptive statistics and multivariate regressions. As a result, study participants' SEP including age, family type, monthly expenditure, type of house, and region was significantly associated with environmental exposure. Also, while adjusting for SEP, environmental exposure such as allowing indoor smoking was associated with self-rated health and depression of study participants. The study findings showed inequality in environmental exposure and health outcomes by SEP in Korean elderly. Environmental exposure was associated with health outcome even after adjusting SEP, and this implied that environmental exposure could be a critical factor in explaining heath inequality by SEP. Further studies are necessary to better understand the causal relationships among SEP, environmental exposure, and health outcomes.

Background: Korea's recent suicide problem has been the most serious in the world. This study was conducted to identify factors related to suicidal ideation of Korean adults and to identify the association with socioeconomic deprivation. Methods: The 17th Korea Welfare Panel Study (2022) raw data was used, and 10,065 adults aged 20 years or older who responded to all major questions were selected as subjects for the study. SAS ver. 9.4 program (SAS Institute Inc., USA) was used for data analysis. Multiple logistic regression analysis was performed to identify the association between socioeconomic deprivation and suicidal ideation. Stratified analysis was performed to confirm the difference by subjective health status and gender. Results: For every 1 unit increased in socioeconomic deprivation, suicidal ideation increased 1.5 times (odds ratio [OR], 1.48; 95% confidence interval [CI], 1.37-1.61). People with good subjective health status showed 1.3 times higher suicidal ideation (OR, 1.30; 95% CI, 1.12-1.52) for each unit increased in socioeconomic deprivation, and those with poor subjective health status showed 1.6 times higher (OR, 1.58; 95% CI, 1.43-1.75). Conclusion: As socioeconomic deprivation increased, suicidal ideation increased. Therefore, policy measures should be prepared to improve the level of more multidimensional deprivation and subjective health status in order to lower the suicide rate of Korean adults.

This study analyzes the economic efficiency of utilizing hot waste water at a thermoelectric power plant, which is part of recent projects supported by the Korean government to foster new energy industry. The author proposes an institution that provides economic incentives to promote the project. Based on a method of calculating Levelized cost of energy (LCOE), this study finds that the LCOE of using hot waste water at power plants is higher than that of oil boiler, biomass and a power plant's auxiliary steam but similar to that of the geothermal system. Also, according to sensitivity analysis on the LCOE of each element in the system of using hot waste water, a distance of heat supply is most sensitive. Therefore, this study shows that when the government devises an incentive-based institution to expand the project of utilizing hot waste water, it is necessary to establish Renewable Energy Certificate (REC) weights that are differentiated by a distance of heat supply.
