It is getting difficult to manage water resources in South Korea because more than half of annual precipitation is concentrated in the summer season and its intensity is increasing due to global warming and climate change. Artificial recharge schemes such as well recharge of surface water and roof-top rainwater harvesting can be a useful method to manage water resources in Korea. In this study, potential artificial recharge site is evaluated using geographic information system with hydrogeological and social factors. The hydrogeological factors include annual precipitation, geological classification based on geological map, specific capacity and depth to water level of national groundwater monitoring wells. These factors were selected to evaluate potential artificial recharge site because annual precipitation is closely related to source water availability for artificial recharge, geological features and specific capacity are related to injection capacity and depth to water is related to storage capacity of the subsurface medium. In addition to those hydrogeological factors, social aspect was taken into consideration by selecting the areas that is not serviced by national water works and have been suffered from drought. These factors are graded into five rates and integrated together in the GIS system resulting in spatial distribution of artificial recharge potential. Cheongsong, Yeongdeok in Gyeongsangbuk-do and Hadong in Gyeongsangnam-do, and Suncheon in Jeollanam-do were proven as favorable areas for applying artificial recharge schemes. Although the potential map for artificial recharge in South Korea developed in this study need to be improved by using other scientific factors such as evaporation and topographical features, and other social factors such as water-curtain cultivation area, hot spring resorts and industrial area where groundwater level is severely lowered, it can be used in a rough site-selection, preliminary and/or feasibility study for artificial recharge.

서정아(Seo, Jeong A) 한국사회복지학회 2018 한국사회복지학 Vol.70 No.2

본 연구는 개인수준 사회자본과 국가수준 사회지출이 후기 청소년 주관적 복지감에 미치는 영향을 다층분석함으로써 후기 청소년 행복을 설명하는 개인수준, 국가수준 설명변인을 규명하고자 실시하였다. 주관적 복지감을 행복감, 생활만족도, 사회자본을 사적 대인신뢰, 사회적 대인신뢰, 사회 조직신뢰, 정부 조직신뢰, 비공식적 집단 관계망, 공식적 집단 관계망, 규범, 사회지출을 고등교육지출, 직업훈련지출로 살펴보았으며 OECD 16개국 19-24세 후기 청소년 1,617명을 대상으로 위계적 일반화 선형모형 분석, 위계적 선형모형 분석 등을 실시하였다. 개인수준 측정변인과 국가수준 측정변인을 모두 투입한 결과 사적 대인신뢰, 사회적 대인신뢰, 사회 조직신뢰, 정부 조직신뢰, 비공식적 집단 관계망, 규범이 높아질수록 행복감과 생활만족도가 높아졌으며 공식적 집단관계망이 높아질수록 생활만족도가 낮아졌다. 직업훈련지출이 높아질수록 행복감과 생활만족도가 높아졌으며 고등교육지출은 행복감과 생활만족도에 영향을 미치지 못하였다. 연구결과를 바탕으로 결론 및 논의를 제시하였다. The purpose of this study is to establish the effects of social capital and social policy as efforts of society and the country to enhance subjective well-being of the late adolescents. The following research questions were established. First, what effect does the social capital have on the subjective well-being of the late adolescents? Second, what effect do the social expenditures, have on the subjective well-being of the late adolescents? As the methods of the analysis, the hierarchical generalized linear model and hierarchical linear model analysis was conducted using HLM 7.0 for Windows program. The higher the private interpersonal trust, the higher the governmental organizational trust, and the more active in participation in informal networks, the higher the life satisfaction was. It can be seen that the larger the formal group networks, the lower the life satisfaction of the adolescents became. The life satisfaction of the late adolescents were not raised just because the government increased the investments in higher education that is represented by universities, and when the training expenditures with regard to active labor market policy increased, the adolescents highly perceived the life satisfaction, showing the same results as in the case of the feeling of happiness.

This study proposes an idea for energy saving in apartment machine rooms. A conventional district heating system is equipped with constant-flow pumps and bypass valves to regulate pump differential pressure. Each family unit is equipped with a constant-flow on/off valve. This leads to excessive hot water circulation and a high return temperature. To reduce energy loss, this study assumes that each family unit is renovated with a heating valve which regulates the return temperature at 35℃. The hot water supply pump is also replaced with a pump with an inverter to vary flow rate. Expected energy savings is then estimated from field test data. According to the results, pump electricity consumption was reduced by 6,100 kWh for a family unit building over about half a year. The supply temperature can also be lowered by 5℃, which can contribute to a production of electricity of 10.3 kWh/ton of hot water.

Cowden`s disease, also known as various hamartomatous malformations of multiple organs, is a rare autosomal dominant disorder. The most important feature of Cowden`s disease is its frequent association with malignant neoplasm, particularly in the breast and thyroid gland. Cowden`s disease with malignant neoplasms, is quite rare in Korea so far. We report a case of Cowden`s disease associated with breast cancer in a 41-year-old female who underwent routine health cheek-up. (Korean J Gastroenterol 2007;49:183-186)
