농촌마을 빈집의 활용방안에 관한 연구 - 김제 하천마을 중심으로 -
심유현,신병욱,남해경 한국농촌건축학회 2022 농촌건축 : 한국농촌건축학회논문집 Vol.24 No.1
Currently the population of rural areas in Korea continue to decline due to low birth rate, aging population, and migration. This phenomenon is accelerated over time. And as a result, there are some declining phenomenon in rural society. And it is same in the residential and basic living conditions of rural villages. The increase ratio of empty houses exacerbates the rural landscape, acts as a cause of crime and bring out various social and economic problems such as worsening settlement conditions and local slums. The study is carried out to prevent this phenomenon by investigating the architectural contents of empty houses in the village, surveyed residents and owners and finally analyzed and synthesized to make a plan to utilize empty houses in the village. This study was conducted from June to December 2021. The conclusions are followings: 1. The empty houses in Korea were 1,511 million in 2020, 8.2% of the total number of houses, whereas those in Jeollabuk-do were 95,412, 12.9% of those of houses, and those in Gimje-city, the subject of this study, were 5,944. It is up to 15.8%. In particular, empty houses in Hacheon village, the site of this study, accounted for the highest ratio, with 25% of the total number of houses. 2. To understand the utilization and improvement of empty houses, surveys and interviews were conducted to residents and owners of Hacheon village in Gimje, and most of the residents submit proposals that empty houses were not desirable in terms of village landscape and safety. The owners don’t have intentions of selling or leasing them. They want to remodel them and rent for a specific period. 3. As the physical condition of the empty houses(9empty houses) 6 empty houses of them are good. 4 of them are in poor condition. 4. By synthesizing these contents, nine empty houses in Hacheon village will be remodeled as the space for those of rural start-up young people, smart farm area, community space and rental housings for rural returnees.

Localization of Eruption-Related Molecules in Developing Rat Incisors
한금동,심해경,김세은,강지혜,김민석,이은주,김선헌 대한구강해부학회 2019 대한구강해부학회지 Vol.40 No.1
A complex and intricate cascades of gene expression is necessary for tooth development, and tooth eruption is one of main events during tooth development. Tooth eruption is considered to be strictly controlled either by signaling or extracellular molecules that are secreted by the tooth germs themselves. There have been numerous reports on the eruption-related molecules; however, there is still a lack of information regarding the preparation of the eruption pathway and the key tissue factors involved. This study aimed to localize the eruption-related molecules such as cyclophilin A (Cyp-A), extracellular matrix metalloproteinase inducer (EMMPRIN), matrix metalloproteinase proteins (MMP-9), receptor activator of nuclear factor kappa-B ligand (RANKL), and osteoprotegerin (OPG) in the developing rat incisors. Immunofluorescence findings revealed that Cyp-A, EMMPRIN, OPG, and RANKL were expressed strongly in the dental lamina epithelium of the rat incisor germs during eruptive movement. OPG was also expressed in the osteoclasts in the apical region. MMP-9, a final tissue resolution molecule, was more widely localized in the area surrounding the erupting incisor. This study suggested that the dental lamina epithelium may play a key role in preparing eruption pathways for the incisor in rats.
