This paper aims to investigate epistemic principles and practical virtue items in Confucism about formation of social capital in a community. First, I have reviewed the basic perspective of Confucism utilizing holistic point of view, which is based on the theory of Yum-Yang, and human relationship in terms of role harmony, which is based on the theory of Si-Wi. I have then explored several items, some of which are Jung and Hwa as an internal value criterion, Ui and Ye as an external one. Analyzing other items such as In and Deok as directional items, Chung-Seo and Hyeol-ku-ji-do as epistemic items and Hyo and Ye as practical ones, I have found out that all of them, mentioned above functioned as factors of social capital in a community. Therefore, we emphasize that Confucian epistemic principles and practical virtue items can not only function as components of social capital in modern communities but have useful and practical implications for policy in modern community welfare.

This article researched the changes of terrestrial local broadcasting companies in a crisis of management. According to the following: First, the structure of the internal organization of local broadcasting companies has been changed to put more emphasis on 'management'. Second, most of the interviewees responded that this change was an inevitable choice. However, some responded that their 'role identity' was changing in a negative direction. Third, these changes have led to the emergence of programs that could undermine public interest. It also showed an increase in the production of 'funding-based' programs and 'mobile first' programs.

The purpose of this paper is illuminating positively the perception and compliance rate of local food principles in Korea. The results are as follows. First, in terms of the perception rate, social trust and local production/consumption are the most important components rather than eco-friendliness. This means the importance of both spatial and social aspects of local food concept. Second, in terms of the compliance rate, social trust and shortened food chain are well complied, rather than eco-friendliness and shortened food miles. Third, in terms of the difference between perception and compliance rate, the social aspects such as eco-friendliness, social trust, and shortened food chain has shown relatively smaller difference than the spatial aspects such as shortened food miles and local production/consumption.

기후변화나 인위적인 요인 등에 의해 수문 자료에 비정상성(nonstationarity)이 나타나면서 정상성 가정 하에서 수행되는 빈도해석으로는 정확한 확률수문량 산정이 어려운 실정이다. 최근 이를 보완하기 위한 비정상성 빈도해석에 대한 연구가 진행되고 있고, 이와 더불어 비정상성 지역빈도 해석에 대한 관심도 높아지고 있다. 비정상성 지역빈도해석은 대개 홍수지수법(index flood method)을 기반으로 진행되고 있는데, 홍수지수와 성장곡선(growth curve)에 시간에 따른 변화를 고려하느냐의 여부에 따라 다양한 형태의 홍수지수모형이 적용되고 있다. 본 연구는 다양한 형태의 홍수지수모형의 성능을 평가하여 비정상성 자료에 적합한 형태를 선정하는 것을 목적으로 한다. 이를 위해 위치 매개변수가 시간에 따라 변화하는 비정상성 GEV 분포(GEV100)를 모분포로 하는 지점들로 지역들을 구성하고, Monte Carlo 모의를 통해 발생시킨 자료에 여러 형태의 홍수지수모형을 적용하여 각 모형의 성능을 평가하였다. 모의실험 결과 홍수 지수는 시간에 따른 변화가 없고, 성장곡선은 시간에 따라 변화하는 형태인 홍수지수모형이 다른 형태의 모형에 비해 대체로 더 정확한 확률수문량을 산정할 수 있는 것으로 나타났다. 또한 우리나라 기상청 관할 강우 관측 지점들 중 GEV100 분포가 적합한 것으로 선정된 지점들을 하나의 지역으로 구성하여 모의실험에서 적용한 것과 동일한, 여러 형태의 홍수지수모형을 적용한 결과 모의실험 결과와 일치하게 성장곡선에만 비정상성 고려된 홍수지수모형이 상대적으로 정확한 확률강우량을 산정하는 것으로 나타났다. 따라서 GEV100 모형 기반의 비정상성 지역빈도해석을 수행하기 위해서는 성장곡선만 시간에 따라 변화하는 홍수지수모형이 적합할 것으로 판단된다.

This article attempts to propose the control planning of townscape color around the historic and cultural heritages. The streets and roads of historic conservation and the changing perspectives to which it gives rise in Stockholm has changed dramatically during this century. New development or changes to existing buildings should be carried out in a way which acknowledges its surroundings and is a good neighbour, both in the cultural and social sense that makes good color design sense. There are many examples of townscape color, but the conservative and the historical streets and roads in the whole of the Stockholm city should benefit from careful design of the environment. To achieve this purposes, some strategies of case study of several streets and roads are reviewed; designing color context to relate to urban architectural design proposals of specific sites of cultural heritages are explored. In all new developments the scale of new buildings and the material finishes and colors used should respect the character of their surroundings and have due regard to the setting of any listed building. Streetscape color of visual assessment proposals should aim to help assimilate the development into the local scene. Important streets and roads should also include color townscape.

Drought is a major natural disaster that causes serious social and economic losses. Local drought forecasts can provide important information for drought preparedness. In this study, we propose a new machine learning model that predicts drought by using historical drought indices and meteorological data from 10 sites from 1981 to 2020 in the southeastern part of the Korean Peninsula, Busan-Ulsan-Gyeongnam. Using Bayesian optimization techniques, a hyper-parameter-tuned Random Forest, XGBoost, and Light GBM model were constructed to predict the evaporative demand drought index on a 6-month time scale after 1-month. The model performance was compared by constructing a single site model and a regional model, respectively. In addition, the possibility of improving the model performance was examined by constructing a fine-tuned model using data from a individual site based on the regional model.

Gangwon-do is one of Korea's most popular tourist destinations, with varying tourism demands and trends across its subregions. It is crucial to identify the characteristics of tourism in each area and compare the tourism patterns over time to devise policies that revitalize tourism in each local government and promote balanced development across regions. In this paper, we classify the regions in Gangwon-do based on tourism data from the last four years and analyze the tourism pattern of each region using the non-Euclidean additive model proposed by Jeon et al. (2021). The model incorporates the proportions of visitors by age groups and the proportions of navigation searches by destination types as two covariates, and the proportions of tourism expenditure types as a response variable. We estimate the model using the smooth-backfitting method and coordinate-wise bandwidth selection. The results are visualized in ternary plots, and changes in tourism patterns over time are analyzed by comparing the ratios of prediction errors to fitting errors.

On the basis of vegetation data collected by point-centered quarter method in analysis in Baekdudaegan of Gangwon province in the area of Hyangrobong, Odaesan, Seokbyeongsan, Dutasan, Deokhangsan and Hambaeksan, the study was carried out to classify forest communities and to evaluate the successional trends. The classification method of cluster analysis was used to make various disordered forests into several common groups for 1,004 sample points all together. By clustering the forests in the six study areas were classified into 28 forest communities, which were subjected to aggregate 8 representative forest communities on the count of species composition and species diversity. They were Mesophytic mixed forest community, others deciduous forest community, Quercus mongolica (dominant) community, Q. mongolica (pure) community, Pinus densiflora - Q. mongolica community, P. densiflora community, Betula ermanii community and Q. mongolica - Pinus koraiensis community. The ecological outlook from the result indicated that P. densiflora community and P. densiflora - Q. mongolica community, which were located in Seokbyeongsan, Dutasan and Deokhangsan around 1,000m above the sea level showed lower species diversity index. On the contrary Mesophytic mixed forest community, others deciduous forest community which was located in Hyangrobong, Odaesan and Hambaeksan mostly in protected area and national park around 1,500m above the sea level displayed higher species diversity index. As the composition ratio of Q. mongolica within a certain community was decreased, the species diversity was generally increased, assumed that abundance of Q. mongolica might be negatively associated with species diversity in the national deciduous forest.
