In order to make the best choice for $CO_2$ abatement using renewable energy technologies, it is important to be able to adapt these technologies on the basis of their sustainability, which may include a variety of environmental indicators. This study examined the comparative sustainability of renewable technologies in terms of their life cycle $CO_2$ emissions and embodied energy, using life cycle analysis. The models developed were based on case studies of bioenergy pilot plant in P city of Kyungki province. Final results were total emission of $CO_2$ in Pocheonsi is 670,041 $tCO_2$, around 500,877 $tCO_2$ for electricity and for heat generation, and 169,164 $tCO_2$ for transportation. When used $1,984\;m^3$/day of waste (pig manure etc.) and operated CHP with wood chips of 144,664 ton/year, the $CO_2$ emission in P city was left as is an emission of 449,274 $tCO_2$ and an abatement of $CO_2$ in this region was increased by 32.9%.

In order to develop some indicies for the evaluation of village health worker's activities and to find out personal characteristics and other factors that affect the activities, an interview survey was conducted to thirty seven village health workers (VHW) in Sunwon, Naega and Bulun townships in Kangwha county, where the Community Health Project of Yonsei University, College of Medicine, has been implemented for the past ten years. In addition, daily activity records of the VHW's were also analyzed. The results are summarized below: First, meeting attendance rates, number of regular family visits, number of antenatal care visits and number of family planning visits were identified as the most meaningful criterion for the evaluation of the village health worker's activities. Second, personal factors that significantly affect the village health worker's activities were identified as age, educational background, living with in-laws, religion, presence of preschool child in the family, holding leader's position of village woman's association concurrently, and duration serving as a VHW. The more aged and the more educated VHWs were the more effective. Those VHWs who were living with in-laws, without preschool child in the family, holding the leader's position of the village woman's association, and the longer service duration were the more effective. Other factors that affect the VHW's activities were the number of households in the target village and the number of natural villages in the target villages. It showed that the smaller the size of number of households and natural villages, the higher the degrees of the effectiveness of the VHW.

Although the educational facility are an important considerations on a social equity standpoint, educational environment in rural areas has been continuously deteriorated by numerous social problems such as decreasing birth rate and increasing of local school closing. The purpose of this study is to evaluate the accessibility of educational environment in rural areas on village level. First, we evaluate physical accessibility based on legally defined commuting distance. Second, the implication of village population of potential accessibility is analyzed. Lastly, the facility centrality index of each village is estimated for assessing the relations of educational accessibility. The main results of this study are as follows; (1) The accessibility of most villages in Pyeongchang-gun is vulnerable that 81.10% for elementary school, 73.17% for middle school, and 82.32% for high school, respectively; (2) The average commuting distance per student considering estimated number of students for each educational facilities indicated 2.75km for elementary school, 4.37km for middle school, and 5.79km for high school; (3) the facility centrality index is highly correlated to educational facilities but not to village population.

최근 우리나라에서 하천 및 유역 환경의 급격한 변화로 인하여 하천 형태가 많이 변하고 있는 추세이다. 특히 사행하는 모래 하천에서 만곡부 사주의 형태 변화가 커지고 있다. 이 연구에서는 이와 같은 모래 하천의 만곡부에서 사주의 변화 특성을 평가하고 그 원인을 파악하기 위하여 이동상 수리모형 실험을 실시하였다. 실험에서 하천 및 유역의 여러 상황 변화를 감안하여 유량, 유사 공급량, 공급 시간, 하천 변형 등 다양한 조건을 상정하였다. 연구 대상하천은 낙동강 본류이며, 중점 수리모형 실험대상 구간은 우리나라의 전통민속마을인 안동 하회마을을 태극형으로 감싸면서 사행하는 만곡부이다. 이동상 실험규모는 수평축적 1/110, 수직축적 1/50로 왜곡도가 2.2로써 비교적 대규모이다. 모형 하상재료는 입경 0.29 mm의 석탄분(anthracite)을 채택하였으며, 현장에서 하상재료조사와 상사해석을 통해 결정하였다. 실험 결과, 유량과 유사 공급량 변화에 따른 사주 변화가 밀접한 관계가 있는 것으로 나타났다. 특히 유사 공급이 이루어지지 않을 때 국지적 퇴적양상을 보였다. 이는 사주 내 식생활착으로 이어지는 계기가 될 수 있음을 확인할 수 있었다. 그리고 설계홍수량 규모에서 구하도와 과거 사주가 재현되었는데, 이는 지역주민을 통해 입증되었다. 또한 천연기념물인 만송정 주변의 모래둔덕의 형성과정이 입증되었다.

This study was carried out to evaluate the performance of Modified Ludzsck Etinger (MLE) process with waste oyster shell media in aerobic tank. Influent flow was 36 L/d and the order of reactor was anoxic, aerobic and sedimentation tank and unit hydraulic retention time was 2 hr, 6 hr and 4 hr, respectively. Sludge recycling rate in sedimentation tank and internal recycling rate were 100%. Media fill rate in aerobic tank was 5%, 10% and 17% and fluid MLSS concentration in aerobic tank was 3000~4000 mg/L. Average TCOD removal rate was 91~93%, TBOD 92~96%, SS 95~96% and when media fill rate was 10% or more, in organic compound removal it could satisfy with wastewater discharge standard. Average total nitrogen removal rate was 70~76% and average total phosphorous removal rate was 58~65%. With media fill rate increasing, total phosphorous average removal rate also increased. For it was that released calcium ion from waste oyster shell reacted with soluble phosphorous. From these experiment results, the MLE process using waste oyster shell as media is a practical method for advanced sewage treatment in rural area.

The purpose of this study is to provide the basic data for planning and designing Village Parks in Seoul in the future, which result from analyzing post-occupancy evaluation. For conducting this study, 10 Village Parks among 45, built between 1996 and 1997, were selected and analyzed. The results of this study are as follows. The degree of satisfaction of 10 Village Parks in Seoul has been evaluated on a scale of 10, to be a 6.68 average. This result means that the most respondents are satisfied with the existing Village Parks in Seoul. The correlation of the degree of satisfaction with major planning factors for 3 types of Village Parks shows that accessibility is the most important factor. As for future directions of planning and designing Village Parks, many kinds of sitting, leaning and resting place need to be provided. It is also necessary to improve the visual quality of the parks with various spatial elements. The research also shows that various facilities for people's use should be provided in Village Parks.

Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.

정부는 2018.2.8일 국정현안점검조정회의를 통해 국무조정실, 금융위원회, 기획재정부, 고용노동부, 중소벤처기업부 등 관계부처 합동으로 "사회적금융 활성화 방안"을 최종 확정하였다. 한국의 사회적금융은 보조 기부행위가 아닌 투자 융자 보증 등 회수를 전제로 사회적기업, 협동조합, 자활기업, 마을기업 등 사회적경제기업에게 다양한 자금을 지원하는 금융활동 전반을 말한다. 현재 민간의 자발적인 금융지원활동도 일부 있으나, 정부 공공재원 중심으로 기존의 서민금융진흥원의 사회적기업 신용대출, 중진공의 정책자금 대출, 신보 지신보 특례보증, 사회적기업 모태펀드 등 중기 서민 정책금융체계내의 사업이 대다수를 차지하고 있는 실정이다. 한국의 사회적금융은 미국과 일본, 영국 등의 선진국에 비하면 이제 태동기로서, 사회적경제기업은 자금 공급부족, 제도 금융권에서의 소외 등 자금조달에 큰 애로를 겪고 있다. 따라서, 공공부문 주도로 자금공급을 확대하고 있으나, 사회적경제기업의 자금수요에는 아직도 크게 미치지 못하는 상황이다. 특히, 지원방식이 짧은 만기, 대출 보증에 편중되는 등 사회적경제의 특수성에 대한 고려가 미흡하여 수요-공급 간 미스매치도 큰 상황과 자금수요자와 투자자를 이어주는 사회적금융 중개기관, 사회적성과 평가 등 시장 인프라도 전반적으로 크게 미비 되어 있어 민간의 참여를 제약하는 것도 그 이유이다. 본 연구에서는 한국의 시회적금융지원제도의 전반적인 현장의 실태를 중심으로 실무적인 측면에서 분석 및 향후과제를 도출하여 관계기관 등에 정책적인 시사점을 제공하고자 한다.
