In this study, thirteen villages in Chonnam province were selected as case study sites and the spatial distribution of the facilities in the villages was examined to provide basic information fur the establishment of rural plans. According to the questionnaire survey, various problem such as environmental pollution, position, scene, management etc. was brought owing to cattle shed, and dissension was more or less seen by scale of facilities, management of facilities and waste, regional factor(stock farming management condition, life style and attitude of inhabitants) and topographical factor (height, position physical aspect of a mountain, distance with water resources etc.) etc.. The facilities could be classified into 6 types based on the their spatial locations: 1) Type 1, facilities located at the waterside; 2) Type 2, facilities located at the entrance of village; 3) Type 3 facilities, scattered in the residential area: 4) Type 4 facilities, collectivized in village; 5) Type 5 facilities, adjoining village; and 6) Type 6 facilities, scattered irregularly inside and outside of village. Based on the classification, possible implementations for the reduction of environmental impacts were suggested. The results of this study could be used as an example of study on the distribution, classification, and rearrangement of environment-impacting facilities in rural areas for improvement of their roles in providing amenity resources.

최근 지식산업센터는 지식산업, 정보통신 관련 첨단업체들이 주로 입주하여 경제적 부가가치를 창출하는 시설로써의 역할을 담당하고 있다. 반면, 지식산업센터 내부에 설치되는 지원시설은 입주기업 지원, 그리고 근로자의 근로환경개선을 위하여 역할을 충실해야 하고, 다양한 활동을 영위할 수 있는 공간을 지원한다. 하지만 정부의 정책 지원이 해당 기업에 한하여 실행되고 있으며, 첨단지식산업센터 내 지원시설에는 어떠한 정책적 지원도 이루어지지 않고 있는 실정이다. 이에 본 연구는 근로자 근로환경 지원을 위한 시설인 지식산업센터 지원시설을 대상으로 다각적 분석을 실시하였으며, 근로자 지원시설의 분석결과, 정리하면 다음과 같다. 첫째, 지식산업센터 지원시설에 대한 적정면적 확보규정 도입이 필요하다. 둘째, 지원시설 중, 설치율이 저조한 시설에 대하여 주변시설과의 공유 방안이 필요하다. 셋째, IPA 분석결과, 상업시설 지원면적이 높은 것으로 나타났으나 문화지원시설에 대한 선호도 및 중요도가 높은 것으로 제시되어, 근로자의 근본적 욕구 및 기대에 부응할 수 있는 이용자 특성을 고려한 지원시설 구성방안이 요구되어진다. 마지막으로 근로환경에 영향을 미치는 시설은 사업초기부터 지구단위계획수법을 통한 계획적 도시관리가 적용된다면 근로자의 생산활동 지원에 많은 기여를 할 것으로 분석된다.

The gut microbiota is a key factor significantly impacting host health by influencing metabolism and immune function. Its composition can be altered by genetic factors, as well as environmental factors such as the host's surroundings, diet, and antibiotic usage. This study aims to examine how the characteristics of the gut microbiota in pigs, used as source animals for xenotransplantation, vary depending on their rearing environment. We compared the diversity and composition of gut microbiota in fecal samples from pigs raised in specific pathogen-free (SPF) and conventional (non-SPF) facilities. The 16S RNA metagenome sequencing results revealed that pigs raised in non-SPF facilities exhibited greater gut microbiota diversity compared to those in SPF facilities. Genera such as Streptococcus and Ruminococcus were more abundant in SPF pigs compared to non-SPF pigs, while Blautia, Bacteroides, and Roseburia were only observed in SPF pigs. Conversely, Prevotella was exclusively present in non-SPF pigs. It was predicted that SPF pigs would show higher levels of processes related to carbohydrate and nucleotide metabolism, and environmental information processing. On the other hand, energy and lipid metabolism, as well as processes associated with genetic information, cell communication, and diseases, were predicted to be more active in the gut microbiota of non-SPF pigs. This study provides insights into how the presence or absence of microorganisms, including pathogens, in pig-rearing facilities affects the composition and function of the pigs' gut microbiota. Furthermore, this serves as a reference for tracing whether xenotransplantation source pigs were maintained in a pathogen-controlled environment.
