The purpose of this study was to analyze and clarify the forest information shown in the Korean Peninsula Forest Distribution Map (KPFDM) printed in 1910. First, the background, process, results, and reliability of the Forest Survey Project (1910), which is the basis of the KPFDM, were evaluated. Next, the information of the KPFDM, preserved as a paper map, was digitized to show forest status and forest type. The results of the analysis can be summarized as follows: Analyzing the Korean peninsula of the 1910 period in terms of the present South and North Korean regions, stocked forests were found to be more widely distributed (73%) in the northern region. The southern region largely consisted of deforested areas, with young-growth trees and unstocked forests making up 80% of all forests there. The northern region had abundant natural forests, with 80% of the forests in Yanggang-do, which currently includes Mt. Baekdu and the Hyesan area, composed of stocked forests. Pinus densiflora was found about 2.7 times more often in the southern region than in the northern region. Large numbers of coniferous trees excluding Pinus densiflora were found in the northern region. In particular, 53% of the forests and 72% of the stocking land in the southern region were composed of Pinus densiflora.

A study on the Joseon Dynasty's furnace walls, excavated from south Korea, was conducted to identify the correlations and differences of the furnace walls found in Jeolla and Gyeongsang regions. Three ruins in the Jeolla region and two in the Gyeongsang region were selected for the analysis. The results showed a layer change depending on the degree of plasticity and difference in the number of layers and particle phase. Furthermore, although the temperature to be subjected to heat was divided into 1300℃ and 1100℃, it was not a phenomenon that appeared according to the region. Additionally, analysis result of major components revealed that the TiO₂ content of most samples does not exceed 1wt%, This means that the furnace did not smelt iron sand or smelted it into low-titanium sand. This study indicated a slight similarity between the furnace walls found in the two regions, and the correlation was determined based on the nature of the ruins, raw materials of the metals ores, and composition of the raw materials constituting the furnace walls.

The permanent monitoring plots were installed in 2001 for long-term monitoring the structure of forest communities at the Piagol(Valley) and Daeseonggol(Valley) in the Jirisan National Park, and monitored the forest structure in the studied sites in 2001 and 2006. Dominant species at Piagol and Daeseonggol was Carpinuslaxiflora and Quercus mongolica respectively. Based on the distribution of major species' stem diameter, the species diversity index was higher in Piagol than that of Daeseonggol. The distribution of diameter in major tree species in the studied sites showed a stable plant community structure. The forest of Piagol, which is positioned in the valley, showed a quite a different composition of species from that of Daeseonggol, which is positioned on the slope. In the last five years, the overall grows rate of Piagol Forest decreased by $6.4m^2$ per hectare, while Daeseonggol Forest increased by about $8.27m^2$ per hectare. I think that this is because of the fact that a lot of large old trees have died.

This study is one of a series of studies exploring the locality of Jeju architecture, in which we focused on the works of domestic architects, rather than those of famous foreign architects, as well as on the locality of the phenomenological aspect rather than the conceptual one, so as to reveal the locality in the present situation. It was revealed that the architects had the following viewpoints with regard to the local characteristics of Jeju: first, the hermeneutic aspect of the locality is the architectural application of the traditional Jeju architecture; second, the phenomenal aspect of the locality involves respect for the landscape and natural scenery of Jeju. There are two main ways in which architects can realize the locality that they envisage. The hermeneutic representation of Jeju would be as a locality consisting of traditional houses. The architects mainly wanted to implement the elements of the private houses through the space layout. The phenomenal representation of the locality would require them to respect the landscape and scenery of Jeju and to implement them in its architecture. This was the case if the landscape or landscape elements were directly borrowed from the buildings, or if the buildings respect the scenery or landscape of Jeju.

충남 서부 활석광산 주변의 수계에 대한 원소 함량특성에 대해 알아보고자 대흥 및 광천광산에 대해 수질 및 하상 퇴적물 시료와 함께 광산 주변 토양 및 모암 시료를 채취, 비교하였다. 대흥지역 퇴적물은 대부분 원소에서 SP가 GN에 비해 높았는데 이는 퇴적물 내 유색 및 무색광물 함량 차이로 판단된다. 절대 함량 비교에서 광물 결정구조 내 쉽게 Mg와 치환하는 원소는 낮은비율을, Fe와 치환하는 원소는 높은 비율을 보였는데 이는 퇴적물 내 주 구성광물내 원소 치환특성을 반영하기 때문으로 판단된다. 절대 함량의 감소 순서와 타원소들과 높은 상관관계(>0.85)의 빈도를 보이는 원소들 사이의 차이는 퇴적물 화학조성에 이차광물과 비정질 광물등의 조성도 반영되었음을 암시한다. 대흥지역 지표수는 대부분 원소에서 MSP가 SP와 GN의 중간값을, MSG는 LGN과 MSP의 중간값을 조여 수계의 혼합특성을반영하는 것으로 판단된다. 절대 함량관계에서는 SP는 GW1과 유사했고, GN은 LGN과 유사했으며, 절대함량은(Mg, Fe), (As, Sc), (Mo, V, Se) 순서로 낮아졌다. 광천지역은 갱내수가 천부 지하수에 비해 대부분 원소에서 높은 함량을 보였는데, 이는 갱내수가 더욱더 많은 물-암석반응을 거친 때문으로 판단된다. 절대 함량은 Mg, Br, Fe, (Sc, Cr), (An, Ni, V)순서로 감소하였다. 갱냉수의 지역간 원소 함량 차이는 사문암화가 우세한 광천지역과 활석화가 우세한 대흥지역 모암들 사이의물-암석 상화반응의 차이를 보여주는 것으로 판단된다 두 지역의 상부 토양 및 모암 조성에서 SP가 GN에 비해 높은 Mg 비, Ni, Cr, Co 등 함량을 보였는데, 이는 사문암 지역 내 Mg, Ni, Cr 등이 풍부한 광물들 탓으로 판단된다. 퇴적물과 수질 사이에서는 함량 경향을 뚜렷하지 않았고 원소에 따라 서로 다른 힘량 차이를 보였는데, 이는 퇴적물 원소 함량이 수계 조성을 반영하는 것이 아님을 나타낸다. 상부-토양-암석-수계의 조성관계에서 대흥지역 지표수 중 SP 조성이, 광천지역은 갱냉수가 지하수의 조성에 가까웠다.

The purpose of this study was to identify the variation factors of hypertension medication rate between regions and to use them as a basic data for establishment of hypertension management business plan which is customized by region. The data were collected from community health survey, National Statistics Office and National Health Insurance Corporation, and were analyzed using the geographically weighted regression. As the result of analysis, the factors that influenced the hypertension medication rate between regions were subjective recognition rate of health level, the rate of medical aid client and the number of health facility per one hundred thousand of population. According to the geographically weighted regression, the total of 230 regional regression models composed of major variables which affected the hypertension medication rate were calculated. However, this study has several limitations that the explanatory power of model is not high and others. Therefore, a follow-up study which is based on the actual data of compliance with hypertension medication will be necessary.

과거부터 수자원분야는 공학적인 측면을 주로 강조하였으며, 따라서 인문사회학적 요소(예, 토지이용, 인구, 생태 환경, 경제발전 등)가 종종 배제된 채 시설물 계획이 이루어졌다. 그러나, 경제가 발전하고 사회의 모습이 복잡해짐에 따라, 수자원 관련 시설물의 계획에 있어 다양한 인문사회학적 요소를 고려할 필요성이 높아지고 있다. 본 연구에서는 사회-수문 모델링 기법을 이용하여 사회-수문 상호 간 순환적 관계를 파악하고, 특히 다목적댐이 인문사회에 미치는 영향을 정략적으로 파악하고자 하였다. 우리나라는 기후변화에 의한 극한가뭄과 홍수발생 빈도가 증가하고 있다. 이에 대한 대책으로, 다목적댐을 건설하여 효율적인 수자원 관리를 하고 있다. 본 연구에서는 대상지역으로 국내 강원도의 횡성댐을 선정하였다. 횡성댐은 하류에 위치한 횡성군과 원주시에 생 공 농업용수를 공급하는 용수원의 역할과 섬강 하류지역에 발생하는 홍수를 방어하는 역할을 하고 있다. 횡성댐 유역의 사회-수문학적 관계를 이해하기 위해 인과지도를 이용한 시스템 요소간의 상호연관성을 파악하였고, 이를 바탕으로 수문학적 요소와 인문사회학적 요소 사이의 관계식을 구성하였다. 수자원 분야에 해당하는 요소로는 생 공 농업용수 이용량 및 댐 저수량과 방류량을 선정하였으며, 인문사회학적 요소는 인구, 공업지역 농경지 주거지역의 면적 및 지역 내 총생산액을 선정하였다. 이와 같은 사회-수문학 요소를 바탕으로 해당 지역의 사회-수문 전체의 동태적 변화를 이해하기 위해 시스템 동적모의(System Dynamics) 모형을 이용한 모델링을 진행하였다. 다목적댐 건설 전 후로 대상지역의 용수 이용량과 인구 및 지역 총생산액 등의 데이터를 수집하여 모델을 검증하였다. 나아가 구현한 모형을 활용하여 향후 기후변화 발생 시 다목적댐이 대상지역의 용수이용 및 인구변화, 지역경제에 미치는 영향을 정량적으로 분석하였다. 본 연구는 인문사회분야와 수자원분야 사이의 영향관계를 이해하고, 모델을 이용한 정량적인 분석을 통해 향후 수자원 시설물 계획 및 정책마련을 위한 의사결정도구로 활용될 수 있을 것으로 기대한다.

Ecomuseum which appeared in France in 1968 and widely diffused over the world, is a new type of museum. The purpose of this museum is not to simply possess and exhibit the existing relics, but to discover the locational senses of a territory by in-situ conserving and interpreting its entire natural and cultural heritages, and to plan the participation of its population and the development of its local community. The significance of this museum can be found in the recovery of disappearing collective memories of a territory, the restoration of the cultural identity of its population and the revitalization of a underdeveloped area. As the majority of these museums are fragmented or open air museums, an 'web ecomuseum' which makes the remote offering of informations about whole dispersed heritages and their holistic interpretation possible by digitalizing, recording, conserving, interpreting and utilizing related heritages, is necessary. This paper considers the possibility of web ecomuseum and its constitution contents and methods through the case of Mountain Mudeung area. Especially, in relation to the latter, this paper suggests a plan which consists of selection of own local themes, construction of digital archives, design of web expositions and production of electronic cultural maps.

The border area between the South and North Korea is considered a stage for promoting Green Détent through the transformation of the Demilitarized Zone into the Green Peace Zone. This paper proposes 'Prosuming-index' composed of items to evaluate the multi-layered nature of industrial and infrastructure projects in the ecological and environmental fields planned in the border area. Based on the prosuming-index, we derived the following four types of potential for Green Detent practice in the border area-first, the Incheon and Ganghwa regions as 'a logistics/human network and agricultural/fishery production area', second, the northern Gyeonggi region as a 'cooperative network area based on the smart technology industries', third, the western Gangwon and the parts of nothern Gyeonggi region, as 'a multiple prosumer's area based on carbon neutral technologies', lastly, the eastern Gangwon region, as 'a transition area from idle or aged infrastructure to green infrastructure through the renewable energy industries'.

This study investigates the occupational mobility patterns of young wage employees at the local level of the labor market and empirically examines the interplay between worker-level and local labor market-level determinants between 2010 and 2020. The 4th to 14th waves of the Youth Panel 2007 were integrated with the Korea Network for Occupations and Workers and the Local Area Labor Force Survey for estimation using hierarchical linear model. Our results indicate that Gross Regional Domestic Product per capita is key determinant of occupational upward mobility. Also, Estimates of employment size, population density, and the unemployment rate of local labor market have different effects depending on the education level and occupational location of youth workers, suggesting that the effects of structural factors of local labor market may not be distributed equally among all youth wage workers. The findings have policy implications regarding the recent rise in inequality and polarization in local labor markets.
