The vitalization of Agro-industrial complex could be an alternative to enhance farmers off-farm income and overcome FTA's impacts on the import of agricultural products. However, it is evaluated the governmental policy on the Agro-industrial complex has not been successfully done as expected. The Agro-industrial complex started to be composed in 1984 and the 427 Agro-industrial complex have been composed nationwide by 2011. Meanwhile, three Agro-industrial complex where 61 factories are running have been composed and two Agro-industrial complex are being under construction in Seocheongun as of 2011. It is investigated that there are constraints in the government supporting systems for Agro-industrial complex. They are; Aged and poor infrastructure facilities, Weak marketing competition, Scattered supporting agencies, and Poor loan system, etc. In this respect, the policy of supporting system was suggested and recommended to vitalize Agro-industrial complex in the study. They are; Better loan system, Improving aged facilities, Marketing support, Assisting technology, Suppling labor power, and Forming factory-network, etc.

Recently, Rural village of japan are enlarging and enriching the service of health, medical and welfare facilities for the elderly. Concentrated arrangement of the three types of facilities is one of the effective ways especially for the small-scale local governments. This paper focus on a questionnaire survey of employees who work in the facilities to evaluate service network. Using this survey data, it is used to make a plan of intensive arrangement. As a result, their satisfaction with concentrated arrangement was considerable high. In particular, they expressed satisfaction with service network between Medical and Welfare. Due to increasing outpatients, the concentrated arrangement has contributed to hospital funds and given emotional security to the aged in welfare facilities. In order to promote service network effect, there are many opinions that management of health facilities(local governments) is needed.

Restoration of earthenware is largely composed of selection of clay, making(forming), and firing. This study lays emphasis on the making method and open-air firing. For making methods, This study used coiling method partly with priority given to ring method. The most significant feature of this restoration work is the making method of tap-forming, in which 외박자(out tap instrument) and 내박자(inter tap instrument) would be tapped and formed. For firing, This study used open-air firing method in the most primitive way. This method needs no special device and equipment and makes the work more simple and easy. The previous study was on the making method by archeological and preservation-scientific research but this study emphasized the restoration work in an actual earthenware maker's position. Through the result of this study, This study wish this would be an opportunity to present another model of various restoration methods for other researchers those who wanted to participate in the restoration and openair firing.

This article is researched to analyze what kinds of projects were conducted by the special grant, the balanced development special account(BSDA), and the municipal projects in the case of Sangjucity and Seochengun, in the introduction time of the bock grants of BSDA and the municipal development plan in 2010. Furthermore this study presents the problems and the direction of improvement. For the territorial integration of a regional development in long-term, I suggest that the spacial grant and BSDA are necessary to be integrated because of ambiguous difference. And also the block grants of current 24 projects in 7 groups should be reclassified as the concept and the functional feature of pluralistic rural development.

우리나라에서는 최근 이상기후로 인해 평균 기온이 높아지고, 여름철에 집중된 강우 특성으로 인하여 하천의 하도와 하도내 식생영향에 따른 수위-유량관계곡선식의 변동성이 높아지고 있다. 하도 내 식생과 하천의 흐름은 서로 영향을 주기 때문에 하도내 식생은 하천 흐름 특성에 핵심적인 요소로 볼 수 있다. 하도의 변동성은 단면 측량 등으로 확인 할 수 있으나, 하도내 식생은 주변 환경에 따라 매년 다르게 나타나기 때문에 이에 대한 모니터링이 필수적이다. 본 연구에서는 만경강 유역에 위치한 전주시(서천교)관측소를 대상으로 2017년~2018년, 2020년의 하도 내 수중식생과 하안 영역의 식생 성장과 소멸 및 식생사주의 모니터링 결과를 바탕으로 수위-유량관계 변화를 분석하였다. 2017년은 하도 내 식생의 성장과 소멸에 따라 저수위 구간에서 다수의 기간분리가 발생하였으며, 중수위 구간은 기간분리가 발생하지 않은 것으로 분석되었다. 2018년과 2020년은 하도 내 수중식생의 성장과 소멸로 인항 저수위 기간분리 이외의 하안영역의 식생 성장과 소멸에 따른 통수능 변동으로 인하여 중수위 기간분리가 추가로 발생하였고, 식생사주에 대한 지속적인 모니터링을 통하여 중수위 구간분리를 추가 검토하였다. 결과적으로 본 연구에서는 하도 내의 식생영향에 따른 유량측정성과를 확보하였으며 확보한 유량측정성 통한 신뢰도 높은 수위-유량관계곡선식을 개발하였고 이를 통해 생산된 유량자료는 정확도가 매우 높은 것으로 분석되었다.

Randomly amplified polymorphic DNA(RAPD) analysis was applied to detect the molecular polymorphisms in Gentiana scabra var. buergeri. A high level of molecular variability was found among wild plants and cultivars. In genetic analysis, eight of twenty primers were selected and 54 amplification products ranged 2. 2 to 0.2 kb were compared. Twenty - nine amplified products showed polymorphic, while five were monomorphic. Twenty of line specific bands were found. In genetic similarity and cluster analysis using PCR products, three wild plants collected from Naejangsan, Daedunsan and Keojedo and one cultivar Seochunjaerae were grouped into one cluster, while cultivar Jinbujaerae and Japanese line separated into another clusters, respectively. The identification of DNA polymorphisms by the RAPD technique will facilitate the selection of the lines from different origin.

Pond ash produced from Seochun Power Station was quantitatively characterized to manufacture geopolymers with a range of Si/Al compositional ratios. Mix consistency was kept nearly constant for comparing the compressive strengths of geopolymers. The amorphous composition of coal ash was determined using XRF and quantitative X-ray diffraction. Different mix compositions were used in order to achieve Si/Al ratios of 2.0, 2.5 and 3.0 in the geopolymer binder. Geopolymers synthesized from coal ash with a Si/Al ratio of 3.0 exhibited the highest compressive strength in this study. It was found that geopolymers activated with aluminate produced different microstructure from that of geopolymers activated with silicate. High silica in alkali activators produced the fine-grained microstructure of geopolymer gel. It was also found that high compressive strength was related to low porosity and a dense, connected microstructure. The outcome of the reported experiment indicates that quantitative formulation method made it possible to choose suitable activators for achieving targeted compositions of geopolymers and to avoid efflorescence.

The purpose of this paper is to examine the geomorphic processes of beach and sanddune development in the Chungcheong-Namdo Province. The sands consist mainly of quartz and feldspar with lesser amounts of mica and other heavy minerals. With the exception of those from the granite, the sands have a very fine texture. Another characteristic of the sand grains is low degrees of roundness and grading indicating that source areas for the material were in the vicinity of the accumulating field. Over the years, the beaches have receded as a response to the decreasing amount of depositional materials. The driving force for the formation and transformation of coastal dunes in the study area is dominant winds from the center of the Siberian High. To some extent, the erosion of coastal dunes has been a global phenomenon. The degradation process occurred most actively when spring tides attacked beaches, berms, and foredunes. The relief and shape of present-day coastal dunes is determined initially by the Pleistocene strata underneath. From the fact that the strata contained traces of frozen structure, it can be inferred that sediment once experienced the process of soil formation.
