  • 최근에 이르러 농촌 인구의 도시유입으로 도시의 주거공간이 절대적으로 부족해지고 있으며, 이는 대도시의 아파트 가격 상승을 유발하는 등 부수적인 사회/경제적 문제를 일으키고 있다. 정부나 지방자치단체에서는 이러한 문제를 해결하기 위하여 대규모의 신도시 개발계획을 추진하고 있으며, 이러한 신도시 개발은 도시화로 인하여 환경적, 수문학적으로 부정적인 영향을 미치는 것으로 조사되고 있다. 도시화는 수문학적으로 산림이나 농경지와 같은 투수지역을 건물, 도로 등의 불투수지역으로 변화시키는 것이며 (Im 등, 2003), 이로 인하여 홍수파의 도달시간이 줄어들고 첨두유량이 증가하는 등의 수문변화를 수반하게 된다. 도로나 건물 등이 대부분을 차지하고 있는 도시지역에서는 지표면이나 식생으로부터 대기중으로 방출되는 증발산량이 농촌이나 산림지역보다 상대적으로 적으며, 강우시 토양중의 침투량과 지표면의 저류량도 도시지역에서는 매우 적게 나타난다. 신도시 개발 전후의 수문순환을 평가하는 방법 중의 하나는 개발예정지에 대한 장$\cdot$단기의 수문/수질 관측을 통하여 개발 전과 개발 후의 유출특성과 수질부하를 정량적으로 비교하는 것이다. 본 연구에서는 도시화로 인하여 대규모의 토지이용 변화가 예상되는 신도시 개발예정지구를 시험유역으로 선정하여 장기적인 수문/수질 모니터링을 실시하고자 한다. 또한, 시험유역에서 계측된 자료와 유역수문모형을 활용하여 개발전후의 홍수 및 유출특성을 분석하고 도시화가 하천의 수문 및 수질에 미치는 영향을 정량적으로 비교분석 함으로써 효율적인 저감 대책의 수립에 활용할 계획이다. 본 연구에서는 국내$\cdot$외의 시험유역의 운영 실태를 조사하고, 신도시 개발 등으로 인하여 급격한 도시화가 진행되고 있는 지구를 시험유역으로 선정하여 유역의 물순환 체계를 조사하고자 한다. 이를 위하여 신도시 개발지구와 도시정비사업지구를 대상후보지로 선정하여 개발계획 및 유역의 특성 등을 조사하고, 시험유역의 선정기준을 수립하여 연구의 목적과 부합되는 지구를 시험유역으로 선정하였으며 선정된 시험유역에 대하여 수문$\cdot$수질 조사 계획을 수립하고, 계측시설을 설치하여 시험운영을 실시하고, 향후 시험유역의 수문계측 및 관리방안을 수립하고자 한다.

  • This study has been conducted to perform the survey on the ecological systems, scenary, and water quality change for agriculturally purposed drainage channels constructed with the application of environment-friendly methods and thus to evaluate the environment-friendly redevelopment effects of them. The main results of this study are as follow: 1. The channels not looking good aesthetically before redevelopment had changed into graceful scenic views from the aspect of landscape architecture as natural-type gently waterside to the channel and naturally-looking water stream. In the village parks developed for the rest of residents, an enough view was secured and thus a wide prospect scope could be obtained. 2. The flora in the channels have increased to 35 families and 82 species from 19 families and 32 species before renovation. As the growth speed of them are slower than externally-brought plants, they can cause some risks to the stability of land slope, including scour by erosion. From that reason, it is necessary to adequately combine the species of the plants both natively growing there and externally-brought planted. 3. In case of water quality, it turned out that, from more than a year after redevelopment, plants began to take roots and the water quality improved. On the contrary, there have been some cases, partly found, that aggravated the quality of water due to the causes like as retention of floating matters by withered plants or plant bodies after the growth of plants in the channels under survey became active, and therefore it is judged that a periodic maintenance of waterways is needed. 4. In case of fishes, all species before renovation have revived, and the population and the number of species have increased after works the formation of puddles in the channels. In waterside grasslands, amphibia and reptiles have not only increased but also been diversified.

  • The 14 cities and guns within Gangwon-do were divided into three regions (urban-rural-integrated type, urban type, and ruralcoastal type), and local voluntary disaster prevention organizations in those regions were surveyed as sample groups. As a result, the urban-rural-integrated type and the urban type were found to be lower than the rural-coastal type in all domains including recognition of disaster crisis, evacuation guidance, preparation of voluntary evacuation, maintenance of disaster prevention system, surveillance & guard, and information delivery. In particular, three types had higher information delivery but considerably lower preparation of voluntary evacuation. As for information delivery, foundations for rapid delivery of disaster information due to establishment and extension of systems for forecasting and warning of local governments were prepared, but as for preparation of voluntary evacuation, it is needed not only to perform consistent training and promotion for preparation for disasters for residents to accurately understand status of disasters but to take measures to secure safe places for evacuation beforehand.

  • 최근 기상이변, 불투수층의 증가와 배수체계개선 등의 요인으로 인한 홍수량의 증대로 하도방어 위주의 현재 홍수방어체제는 지속적인 치수사업의 시행에도 불구하고 오히려 하류에서의 홍수가 격심해지는 등 상당한 어려움에 직면하고 있다. 따라서 최근의 유역종합치수계획에서는 천변저류지 등에 의한 면적 개념의 2차원적 홍수량 분담을 통한 피해의 잠재성을 경감시키고자 하는 방안들이 제시되고 있다. 이러한 기술적 수요의 증가에 따라 낙동강유역종합치수계획, 삽교천유역종 합치수계획 등에서는 중규모 이상의 천변저류지가 검토되었지만 이러한 예는 대하천유역이므로 홍수피해가 빈발하는 농촌지역의 중소규모 하천에서는 계획된 적이 없다. 지금까지 지속적인 하천개수사업으로 2004년말 현재 하천연장 기준으로 전국의 하천 개수율은 78%에 이르고 있다. 이 중 국가하천과 지방1급하천은 약 15%로서 개수율이 약 90%이상으로 높고, 지방2급하천은 약 85%를 차지하나 대부분은 농촌지역에 위치하여 약 70% 미만의 낮은 개수율을 나타내고 있으므로 향후 중소규모유역의 지방2급하천에서 하천개수가 지속적으로 추진될 것이다. 현재 하천정비기본계획이 미수립된 하천구간에 대하여 하도계획시 제방축제에 의한 경제성이 미미한 일부 구간에 무제부의 소규모 아지늪을 조성하고, 홍수파의 전파속도를 저감하여 하류의 홍수집중을 경감시키고 유수 에너지를 감소시키며 아울러 본천의 유수환경과는 다른 습지로서의 정수환경을 창출하여 하천생태계의 다양성을 확보하는 방안도 있을 것이다. 본 연구에서는 경남 하동군에 위치하는 지방2급하천인 주교천에 약 $4000m^2$의 소형 습지(아지늪)를 2004년 3월에 조성하고 2006년 11월에 습지의 어류 및 수생식물에 대한 모니터링을 실시하여 아지늪의 하천생태의 다양성의 달성도를 평가하였다. 또한 주교천에서 홍수량의 증가에 따른 홍수류의 유속 변동과 그에 따른 에너지의 변화를 고찰하기 위하여 HEC-RAS를 적용하고 주교천 아지늪 주변의 수리학적 거동을 고찰하였다.

  • This paper considers the effect of "comprehensive rural community improvement project" in terms of three factors - physical environment, rural tourism, socioeconomic and analyzed the path effect leading to the final outcome - the quality of life of residents, using covariance structure analysis. By doing so, this study looks into why residents prefer the improvement of a physical environment that takes a public nature. The analysis showed that the socioeconomic effect did not have an immediate impact on the improvement of quality of life of residents at a significance level of 5%, whereas the improvement of physical environment had a static effect on the quality of living at a significance level of 1%. Residents' preference for "hardware" or physical environment may be attributed to lack of their understanding of human factors such as social capital. However, analyzing the impact of specific contents of the project on performance, it is found that as projects fail to generate a tangible socioeconomic effect, residents strategically prefer the repair of their physical environment such as public facilities that directly affect their daily lives, so that they can maximize an improvement of the quality of living. Hence, this study suggests that instead of attributing the failure of rural community development projects to residents, macroscopic problems of rural communities and specific contents of projects should be dealt with before the success of any project can be discussed.

  • Since the village maintenance type public housing project was introduced in 2015, the resident needs for regional revitalization and pleasant living conditions are not being met due to the poor performance of the public housing complexes that reflect the surrounding area maintenance plan (village plan) and regional characteristics. The purpose of this study is to suggest a plan to revitalize the village maintenance type public housing project in consideration of regional characteristics as a result of analyzing the needs of local residents through the problems of the village maintenance type public housing project being promoted so far and resident satisfaction. As a result of the analysis based on the public housing project implementation status analysis and resident satisfaction, the plans to activate the village maintenance type public housing project are as follows. First, in order to secure the effectiveness of the village plan, it is desirable to promote the public housing project and the village plan at the same time. It is necessary to secure a budget according to the selection of public offering projects in the village plan, such as promoting public housing projects without setbacks by prioritizing land purchases for public housing sites and establishing specialized strategies considering regional characteristics. Second, a public housing project that responds to local demand is required. The evaluation factors such as continuous promotion of the urban architecture integration plan and strengthening of regional linkage plans such as specialization of regionally tailored designs should be supplemented so that regional resources and village plans are linked with the public housing specialization plan. Third, surrounding area maintenance plan (village plan) should be secured by the strengthen of the legal status or establishing related provisions. It is also necessary to promote system improvement for area maintenance plan (village plan) when selecting a publicly funded public project.

  • 목적: 2017년 지하수를 식수로 사용하고 있는 한 장기요양 정신병원(H병원)에서 A형간염 환자가 집단 발병하여 이에 대한 역학조사를 실시하고 조치 결과를 기술하고자 하였다. 방법: 노출기간 동안 H병원의 근로자 및 재원 환자 234명을 대상으로 사례군 조사 디자인으로 역학조사를 실시하였고, IgM, IgG 혈청검사 및 A형간염 바이러스(HAV)에 대한 PCR검사를 시행하였다. 또한 오염원으로 의심되는 지하수, 병원에서 제공되는 식품 및 인근 저수지의 물에서 HAV 검사를 실시하였고, 검출된 HAV는 유전형 검사를 진행하였다. 결과: H병원 환자 및 직원 234명 중 IgG 양성인 168명을 제외한 66명 중 19명이 최종적으로HAV 감염자로 확인되어 감수성자 중 발병률은 28.8%로 나타났다. 환자, 지하수, 식품(석박지) 및 저수지에서 동일 유전형의 HAV가 검출되어 지하수 오염에 의한 집단발병으로 결론 내렸으나, 최초 오염원은 확인하지 못하였다. 유행 종결 선언 이후 지하수에 대한 관리로 염소소독과 UV 조사를 하였음에도 불구하고 6개월 동안 지속적으로 HAV가 검출되어 새로운 관정을 개발하여 상황을 종결하였다. 결론: 본 연구에서 지하수를 식수로 사용하는 장기요양 정신병원에서 지하수 오염에 의한 19명의 HAV 집단발병을 조사하였다. HAV 항체가 없는 대상자 중에서 HAV의 높은 발병률을 확인하였다. 지하수 수질검사에서 바이러스 검사는 포함되어 있지 않기 때문에 지하수가 HAV에 오염시 HAV 집단발병 가능성이 높고 상당기간 지속적으로 검출되기 때문에 지하수에 대한 관리지침에 바이러스 검출을 위한 방안을 추가하고 관련 법을 정비할 필요가 있다.

  • In 2009 the Korea Ministry of Environment announced 'A Comprehensive Plan for the Improvement of Sewer Service in Rural Area' aiming at reduction of the sewer service gap between urban and rural areas as well as improvement in the residential environment of the rural area. According to the plan, the sewer system supply rate for the rural area is expected to reach up to 75% until 2015 with the budget of 4.7 trillion won (Korean currency). It is not certain, however, that the increase in the sewer system supply rate will accompany improvement of water quality in receiving water because several veiled problems that can occur in small-scale sewer treatment plants are poorly addressed in the plan. In this study, those issues for the small-scale sewer treatment plants and their solutions were discussed based on a case study in which we investigated 19 treatment facilities at two rural regions in Gyeonggi province. This study also included strategies useful for the plan. From the results of investigation, some problems, e.g., high hourly variations but low in flowrates and low mass loading were commonly identified. Although operation parameters in sewer treatment plants require to be modified depending on the mass loading, most of the plants were operated with the initial design parameters which causes the decrease of removal efficiency. In the intensive diagnosis, we arranged and applied solutions (e.g., flow equalization, air on/off time control, etc) to the two selected plants and found out improvement of effluent water quality, especially organic matters (COD and SS) and T-N with better denitrification performance.

  • Although it has been well known that the Saemaul Undong had a direct relation with the water resources development during 1970's, its contribution to the water resources and increased income in rural communities has not been thoroughly quantified so far. In order to assess the contribution of the Saemaul Undong in terms of rural water resources development, we investigated various historical data produced by the central and local governments in relation to water resources development. The results show the direct and indirect contribution of the Saemaul Undong to the water resources development in rural communities such as sewage works, water supply facilities, shared wells, and river works. The results also showed a positive relation between per-house income in rural communities and areas of irrigated paddies, which were rapidly increased during 1970's. These results can be utilized to transplant the positive aspect of the Saemaul Undong to developing countries focusing on water resources development in rural areas.

  • Although the rate of women farmer's participation in agricultural activities have been increased upto 52.7 % as of year 2003, Korean society has not fully recognized their roles in rural society. According to the agricultural basic law, most of rural women were engaged in agriculture as full time job, however, only about 11% of them could have supporting evidence of themselves as farmer having legal right. If women farmers faced some unexpected things such as a traffic accident, insurance company would not reward them as farmers unless they provide written proof of their job as farm worker or farm owner. Based on lawyer's legal advice, the authors developed a diary called "Saenghwalilji", a daily diary based on their time use and bookkeeping to prove the fact of their contribution to income generation of the farm. After examination of the diary, 18 persons out of 29 volunteers kept two types of dairy for the period of two weeks, and they reported it was very useful. Finally the better one of two was selected after reflecting the suggestions from the respondents. The "Saenghwalilji", will be very useful proof of women farmer's contribution to income, at the same time improving their farm management through better use of daily life time.
