폐탄처리과정에서 오염된 중금속 오염토양의 정화에 있어 무기산(HCl), 중성염($CaCl_2$), 킬레이트제(citric acid, $Na_2$-EDTA)들을 이용한 토양세척 가능성을 평가하였다. 실험에 사용된 추출액(HCl, $CaCl_2$, citric acid, $Na_2$-EDTA)들의 추출효율은 HCl > citric acid > $Na_2$-EDTA > $CaCl_2$의 순으로 나타났는데 HCl(1.0 M)에 의해서 Cd, Cu, Pb와 Zn이 초기농도 대비 각각 82%, 86%, 80%, 46% 정도 추출된 것으로 나타났다. 추출효율과 반응액의 pH 간에는 고도의 음의 상관관계가 존재하였다. 폐탄약처리장 부지 토양 중 중금속은 탄산염결합태, Fe, Mn-산화물 결합태 형태로 존재하고 있었는데 HCl, citric acid 세척에 의해서 이들 분획의 현저한 감소가 이루어졌지만 이동성이 상대적으로 큰 치환태가 증가되는 것으로 나타났다. 이동성이 큰 분획의 증가는 지하수 오염 등의 문제를 야기시킬 수 있음으로 이에 대한 적절한 관리가 필요할 것으로 판단된다.

본 연구의 목적은 논의 중간 낙수 기간 동안 미꾸라지의 이동 특성을 살펴보는 것이다. 실험 결과, 미꾸라지는 중간 낙수 초기에는 배수로 쪽으로 수로가 형성되어 둠벙보다는 배수로 쪽으로 이동하는 경향이 있었다. 전체 표지한 미꾸라지 중 약 3.0%가 배수초기에 배수로를 통해 농업용 배수로로 이동한 것으로 나타났다. 중간 낙수가 완료되어 논에 물이 없는 시기에는 전체 표지 미꾸라지 중 5.0%의 미꾸라지가 둠벙으로 이동하여, 중간 낙수기간 동안 둠벙을 피난처로 이용한다는 것을 알 수 있었다. 실험기간동안 표식한 미꾸라지 중 논 바닥을 파고들어 가는 것은 채집되지 않았다. 둠벙이 있는 논에서는 바닥을 파고 들어가기보다는 둠벙으로 이동하는 것을 선호한 것인지 아니면 표식에 의한 스트레스로 바닥을 파고들어갈 힘이 부족했던 것인지에 대해서는 추가적인 연구가 필요하다. 둠벙과 논에서 채집한 미꾸라지의 소화관 내용물을 분석한 결과, 둠벙에서는 동물성 먹이가 86.1%, 식물성 먹이가 13.9%를 차지하여 동물성 먹이가 매우 우세하였다. 둠벙에서 채집된 미꾸라지 중 90% 이상이 먹이를 섭식하고 있었으며 10% 정도가 공복상태를 보이고 있어 표식 후 방류한 미꾸라지가 둠벙에서 정상적인 섭식 활동을 한 것으로 사료된다. 반면 논에서 채집된 미꾸라지는 모든 개체가 공복 상태를 보이고 있어 섭식활동에 장애를 받은 것으로 나타났다.

매토종자는 식물의 장기 보존과 식생 동태에 기여하며, 토양 깊이에 따라 다양성과 밀도가 감소하는 특성으로 인해 군집의 다양성 감소과정 이해에 필요한 핵심관점(예측성 및 무작위성)을 제공한다. 우리는 한반도 온대중부 식생기후의 성숙림인 광릉숲에서 지표식생을 포함하여 토양층위(상토 및 하토) 별 종조성 및 다양성의 변화 및 구조화 양상을 분석하였다. 수직 10 cm 차이를 두고 채집된 두 층의 토양에서 27과 40속 44종 3변종 47분류군의 총 934개체가 발아하였다. 광릉숲의 매토종자는 초본의 구성 비율보다 목본 식물의 다양성 및 발아 밀도가 높았고, 빈터종보다는 가장자리종이 풍부하였다. 생육형을 비롯한 대부분의 비교 특성에서 종 풍부도와 발아밀도는 감소하였지만 큰 편차에 의해 통계적 유의성은 없었다. 상토 및 하토에서 종조성의 집단 내 변이성은 유사하였고, 공통 출현종(제타다양성)의 감소 및 종의 잔존 확률 변화 경향 역시 거의 유사하였다. 토양 내 두 군집 종조합의 구조화 과정은 멱함수보다는 지수 상관으로 적합되어 무작위 과정의 우세를 보였다. 광릉숲에서 토양 깊이(10cm) 별 군집 종조성 및 다양성의 양상은 형질 특성과 상호작용 보다는 종자의 수직 이동에 따른 이입 및 소실의 임의 과정(stochastic processes)에 의해 구조화되는 것으로 평가되었다.

This study aims to examine and develop a Triple Helix model for social innovation to eradicate pervasive poverty in developing countries. To do this, this study explores and analyzes the Rural Saemaul Undong (RSU), a rural community development movement for eradicating poverty that was driven by the South Korean government during the 1970s. First of all, this study explores the characteristics of the RSU and explains why the RSU was a social innovation. To support and explain why the RSU was a successful social innovation, this study analyzes the roles and activities of three distinct actor groups: the chief policymaker and his aides who presented the vision and purpose, or the "why" of the Saemaul Undong; central and local government officials who were the planners and managers who showed "how" to plan and drive it; and village Saemaul leaders as the drivers and coaches showing rural villagers "what" to do. Based on this analysis, this study develops an actor-based Triple Helix model for social innovation to eradicate poverty.

The Saemaul Undong has brought great improvements tothe life-style environment of rural communities, but it has not been able to focuson a health program. In order to improve rural health, develop human resources, and utilise the nation's manpower, the Saemaul Undong should focus on a community health project. Mobilizing the manpower for such a project can be done by providing opportunities for youth and young adults, especially village women, to betrained as primary health caretakers. This project can be achieved through the joint support of the Ministry of Horne Affairs, the Ministry of health and Social Affairs, and other Ministries. It will take decision and courage by government officials to implement such a grand plan, but it is a very crucial task to promote primary health care throughout the whole nation. This calls for top leader's concern & will to adovocate and support a 'Saemaul Movement for health', giving health asfirst priority to the Saemaul Undong as afresh political drive of the fifth Republic of Korea Government.

The demand for green tourism has increased in Korea. The increasing demand for green tourism caused is by reduction of working hours and longing for rural life. Moreover, many view amenity regarded as a good resource of green tourism. Amenity is however an abstract and complex idea. Even though many people were interested in amenity, the movement or practice of amenity in Korea was still as its in infancy stage. This paper was an exploratory study of amenity and paving the way for further studies on amenity in Korea. The objectives of this study were 1) to explore the philosophical background, origin and history, and classification of amenity, 2) and decide on future course of using amenity for rural viability.

Under the colony of Japanese Empire, libraries of Hyanggyo's(a Confucian temple and a old-time School belonging to it) property a n.0, ppeared 45 libraries. Effects of these libraries are as follows: 1. Libraries of Hyanggyo's property impeded Korean people's enlightenment works in the aspect of a save the Nation movement spread all over the country by taking in Confucian scholars and those who work for the good of the locality. 2. It having prepared a point to civilize Koreans for Japanizing as far as rural and fishing community through libraries of Hyanggyo's property. 3. Though many libraries of Hyanggyo's property were closed, a quite libraries became the predecessor of Korea modern library which linked with public libraries.

The rich cultural backgrounds and practices of children from native cultures are often absent in classroom instruction, as teachers might feel that they have inadequate knowledge and backgrounds in the unique practices of these populations. Historically, children from native cultures have had challenging educational experiences and poor educational outcomes. To address these challenges, we propose a Family and Culture Based (FCB) framework that draws from family-centered practice, asset-based practice, and culturally responsive pedagogy. This article describes the three steps of the FCB framework, which uses a teacher-as-learner approach to instruct students from native cultures by engaging teachers in reflection, gaining knowledge about the cultural practices of the family and community, and integrating the new knowledge into practice. We use a Pacific Islands case (Native Hawaiian family) and a Pacific Northwest case (First Nations family) to illustrate the potential benefits of using the FCB framework with indigenous students.

In these days, our social infra which are computer and internet has been developed and our community has been digitalized with a large quantity information that can be sharable or productive. So we can say that older knowledge organization based on the man power is changing with automatical and intellectual aspect. Thus we have to apply this movement to get the high efficiency and the competitive power in the organization and to take the voluntaries attitude of operator with real time inputting or fast calculating speed. Beside most of developed countries are owned their power system analysis software. Like kind of this facts can affect for national reliance. So in this paper we propose that the suggestion for both field power system and IT how these can be cooperated. The note that this paper is came from the project which name is Graphics Power Flow analysis.

In this study the pore water pressures were measured in sea dike constructed with the sand dredged in the sea, and they were analyzed with the hydraulic head loss rate to estimate quantitatively the state of blocking seepage in the sea dike embankment. Blocking state was expressed as the number between 0 and 1. the number of 1 means the state of perfectly blocking seepage and the number of 0 means the state of sea water being passing free. The deeper the installed position was the lower the hydraulic head loss rate was and the longer the seepage path length was the higher the hydraulic head loss rate was. The estimated R-squareds were close to 1, which means that the embankment was steady state without movement of soil particles.
