본 연구에서는 쏙류의 고밀도 서식 때문에 2008년 이후 피해가 급격히 증가하고 있는 한국 서해안 갯벌의 패류양식장에서 착저 초기에 쏙과 가시이마쏙의 초기 성장, 서식 깊이, 상대성장 특성을 구명하여 물리적 제거 또는 포획에 관한 기초적 생태자료를 확보하고자 하였다. 5월 초순에 갯벌에 착저한 어린 쏙은 8월 이후에 두흉갑장이 10 mm 이상으로 성장하였고, 갯벌에 착저 후 1년 경과 시 두 흉갑장 (CL)과 전장 (TL)이 각각 14.21 mm, 42.28 mm까지 성장하였으며, 주 성장 시기는 4~10월이었다. 당년산 어린 쏙의 서식 깊이는 성장과 더불어 착저 후 약 6개월 경과 시까지 빠르게 증가하였다 (7월 5 cm, 9월 12.5 cm, 11월 28 cm). 어미 쏙 (평균 두흉갑장 28.50 mm)의 연중 서식 깊이는 10~93 cm이었다. 쏙의 두흉갑장 (CL)-전장 (TL), 두흉갑장-습전중량 (TWW) 간 상대성장을 분석한 결과, 두흉갑장 26~35 mm 크기에서는 쏙의 습중량이 천수만 입구의 주교 갯벌에 비해 천수만 내측의 사호리 갯벌에서 1.2~4 g 더 무거운 것으로 예측되었다. 본 연구에서 밝혀진 당년산 어린 쏙의 착저 후 초기 성장과 서식 깊이의 증가 특성으로 볼 때, 어린 쏙이 바지락 양식장 등에 정착하여 피해를 주는 것을 줄이기 위해서는 5~6월경에 쏙의 착저 여부를 주의해서 관찰해야 하며, 다량의 쏙 서식이 확인되면 갯벌 속에 30 cm 보다 얕게 굴을 파고 서식하는 8월부터 12월 사이에 어린 쏙을 제거하기 위한 다양한 노력을 기울일 필요가 있을 것으로 판단된다. 또한 보령지역 어미 쏙의 시기별 평균 서식 깊이 면에서 볼 때 1차 제거 적기는 쏙들이 표층에 가장 가까워지는 3월부터 5월 초순, 2차 적기는 10월 중순부터 12월 초순으로 판단된다. 쏙은 갯벌양식장에서 공간점유와 먹이 경쟁 등 인간의 경제활동에는 부정적인 영향을 주지만, engineering species로서 갯벌에 수많은 구멍을 깊게 뚫어줌으로써 다양한 생태계적 순기능도 수행하고 있으므로 친환경적이며 합리적인 대응 방안을 지속적으로 모색할 필요성이 있을 것으로 판단된다.

The old house at No’eun-ri, located in Hongseong-gun Hongbuk-myeon of the Chungcheong Nam-do province, really seems like the old house of late Seong Sam-mun who died in 1456. The original structure of the house seems to have been symmetrical, in terms of its left and right sides, and the females’ chamber(Anchae) as well as the guest quarters(Haeng’rang-chae) would have featured a Matbae(맞배) fashion. The flank chamber and corridor would have displayed a multi-storied shape, and people would have been able to traverse the inside of the house all the way to the second story of the residence. We can see such shapes and dispositions from other ‘口’-shaped houses — found in Chungnam and Gyeongbuk regions — which are now considered as distinct characteristics of certain residences constructed before the war with the Japanese in the 1590s, confirmed from extant vestiges and historical records of that time period. It can be concluded that the old house at No’eun-ri does harbor the traits and elements that resembled the upper class residences of the Joseon dynasty’s early half period.

1978년에 규모 5.0의 지진이 발생한 홍성지역에 발달한 단층대의 전기, 전자적 특성을 조사하였다. 전기, 전자 탐사는 최근 토목공사현장에서 단층대 및 파쇄대 등의 연약지반을 확인하기 위한 수단으로 널리 쓰이고 있으며 이들 탐사로부터 얻어지는 전기비저항 구조는 연약대의 공간적 분포를 효과적으로 파악할 수 있는 정보를 제공한다. 홍성지역에 위치한 단층대를 가로질러 쌍극자배열 전기비저항탐사와 MT (Magnetotelluric) 탐사를 실시하였으며 역산을 통해 단층대의 전기비저항의 분포를 추정하였다. MT 탐사는 주단층대를 가로지르는 2.9 km의 측선상의 18측점에서 실시하였으며, 자기쌍극자를 인공 송신원으로 사용하였다 전기탐사는 단층대를 측선의 중앙으로 하여 전극간격이 50 m인 쌍극자배열전기비저항 탐사를 실시하였다. 두 탐사 결과는 예상단층선을 따라 좌우지역의 전기비저항이 서로 다른 양상으로 발달하고 있음을 보여주고 있으며, 특히 예상단층선을 따라서는 뚜렷한 저비저항대가 깊게 발달해 있음을 보여주고 있다. 홍성지역의 단층대에서 낮은 전기비저항분포를 보이는 부분이 수직으로 잘 발달해 있다는 것은 최근에 두 차례의 지진이 발생한 것처럼 이 지역 단층이 활동 중인 단층이라는 사실과 일치하는 결과를 보여주는 것이다. 본 연구 성과는 앞으로 홍성단층 뿐만이 아니라 우리나라에서 발생하는 지진들에 대한 연구에 기초 자료를 제공할 것이라 기대된다.

The purpose of this study is to analyze the cases of Asan-si and Hongseong-gun in Chungcheongnam-do to derive the direction of development of the school meal support center and improvement of the school meal policy in connection with local food. We conducted a survey on the importance and performance of school meal support policy and local food supply policy for nutritionists in two areas. In addition, we identified the issues to be improved intensively and the issues to be continuously managed over the medium to long term, and suggested directions for improvement using IPA. As a result of the importance-performance analysis of school meal support policy and local food supply policy, both Asan-si and Hongseong- gun. focused on improving the price and quality of local food.

Rural development policy has changed from hardware based development to community revitalization. The purpose of this study is to analyze social network of collaborative activity among rural organizations as fundamental of community. The material used in this study is a record of collaborative activites in the community newsletter of Hong-Dong area. 161 of collaborative activities (links) and 75 of organizations (nodes) are investigated in network. 6 collaborative activity type (‘Education’, ‘Socializing’, ‘Meeting’, ‘Culture’, ‘Event’ and ‘Labor’) is classified. ‘Socializing’ is inclusive of approximately half of whole network (50.67%). Closeness centraization, degree centralization and betweenness centralization are measured on top in ‘Education’, ‘Meeting’ and ‘Event’ type. Scatter plot analysis using degree and betweenness centrality index, ‘Maeul Revitalization Center’, ‘Balmak Library’, ‘Woori-Maeul Medical Co-op’, ‘Support Center for Female Farmers’, ‘Hongdong Middle School’ and ‘Mundang Sustainable Agriculture Education Center’ are resulted as the core organization in network. Geographical distribution of collaborative activity is not only concentated in Hong-Dong Myeon but also networked with adjacent administrative district. This study finds its purpose in the detailed analysis of network characteristics of collaborative activity within Hong-Dong area which is representative developed rural community in Korea

The Hongseong-Gun school food service center (Hongseong SFSC) that is managed directly by local government is supplying local environmentally friendly foods from 2014. This study aimed to analyze a case on Hongseong SFSC and to propose improving directions. Hongseong SFSC showed higher supply ratio (67.4%) of local environmentally friendly foods compared to the other centers. The operation effects of this center are reliably price of farmer’s products, increased consumption of local agri-products, school food confidence, and so on. But there are many problems on this operation. Improvement directions of SFSC for local food system are as follows: Firstly, the supply range of foodstuffs is needed to establish quality standards to increase foodstuffs quality. Secondly, guidelines for creating a fair commission fee structure should be established. Thirdly, the contract issues between the center and schools need to be resolved by governance system. Fourthly, local environmentally friendly agricultural cultivation and cropping systems are required to establish reliably supply of farmer’s products.

The aim of this study is to establish resident-participative primary design of integrated rural development project with master planner by setting principals of open competition and transparent decision-making about village-to-village or business-to-business unit enterprise in Onui area, Hong-seong Gun. For effective processing, software projects such as residents education and rural landscape planning are simultaneously conducted for enhancing project understanding and comprehensive development plan including related post project. Above all, competition teams for individual project were organized to establish the resident-participative primary design using survey tables of residents demand. In 6 months resident-participative processing of primary design, continuous education and visiting to advanced area are conducted in team unit. Strengthened ability of team unit can be used in management and maintenance after project development. To do this, residents with the same opinions gathered as one competition team and identified business plans such as village asset, business location, size, program, and method for land securing. Favorable decision-making process by residents who are audience in project presentation of competition team has conducted. After selecting competition teams, continuos consulting are operated for establishing operation and management for developed or remodeled facilities through repetitive education and visiting advanced area. In this process, unit project suggested by competition team are completed. Preliminary selection was conducted by experts who were entrusted by residents. After residents agreement of project main stream such as major facilities and location, final detailed cost of projects are work out. Suggested process in this study which choose the final project by residents would improve residents' voluntary participation in integrated rural development project through open competition in establishing primary design.

The purpose of this study is to analyze the problems of operating the Direct Payment Program for Rural Landscape Preservation and to derive the way of improvement based on case study for three areas in Bonghwa-gun, Cheongwon-gun, Hongseong-gun. The most important factor for the program is farmer's consciousness and positive participation of the farmer who are the subject of this project. Even if farmers are not satisfied with the amount of direct payment income, they try to create income by utilizing landscape preservation crops. Particularly current unit payment dose not surpass the for the crops farm operating costs and payment time is not appropriate for the farming cycle. Hence, it needs to be considered increasing unit payment and rearranging the payment time. Also, we need to introduce incentive system based the degree of fulfillment of the Direct Payment Program in each areas. In general the Direct Payment Program for Rural Landscape Preservation has potentiality to contribute farmer's income stability and the vitalization of region with three revisions.
