  • 본 연구에서는 1일부터 최대 7일까지의 시간을 두고 남한 전체의 유출량에 대한 예측 모형을 제시하고자 한다. 이를 위하여 LSM (Land Surface Model) 모형을 사용하여 유출량을 모의하였고 이 과정에서 미 계측치에 대한 유출량을 예측하기 위하여 Xgboost (Extreme Gradient Boost)를 활용하여 매개변수를 지역화하였다. 이러한 지역화 기법을 통하여 남한 전체의 유출량에 대한 그리드화 된 유출값을 얻을 수 있었다. 또한 본 연구에서는 기상 예측자료를 유출량에 대한 예측으로 변환하기 위하여 Stacking 앙상블 기반의 수문학적 후처리 기법을 사용하였다. Stacking 앙상블 기법은 Base-learner와 Meta-learner의 조합으로 이루어 지는데 본 연구에서 새롭게 사용되는 패널티 기반의 분위회귀분석 방법론은 기존의 방법론과의 비교에 있어서 유용한 것으로 파악되었다. 결과적으로 본 연구에서는 총 7일의 앞선 시간의 예측에 있어서 한반도 전체의 유출량에서 비교적 짧은 시간에 대한 예측인 1일과 2일에서의 예측은 실질적으로 사용이 가능한 것으로 파악되었다.

  • Housing market is segmented through 1) housing supply classified by housing characteristics and 2) housing demand classified by different housing opportunity of household. Moreover, neighborhood plays a role in intensifying housing market segmentation as a factor affecting on decision making relevant to housing supply and demand. while segmented housing markets have different mechanism, existing studies on residential differentiation and housing market have overlooked the characteristic differences among housing submarkets as the studies presume metropolitan housing market to be a single housing market. while the concept of 'residential differentiation' pays much attention on spatial pattern after the ecological approach appeared, the concept of ‘housing submarkets' is explanatory of the process of urban space structure formation. Analysis on housing submarkets makes up for the weak points of the behavioral approach inquiring into socio-economic constraint and different housing opportunity of household.

  • Decay rate and nutrient dynamics during leaf litter decomposition of deciduous Quercus acutissima were compared between Gongju and Jinju for 33 months from December 2008 through March 2011. Percent remaining weight of Q. acutissima leaf litter after 33 months elapsed in Gongju and in Jinju was $41.2{\pm}0.4%$ and $28.3{\pm}0.6%$, and decay constant (k) was 0.39 and 0.61, respectively. Decomposition in Jinju was significantly faster than that in Gongju. This seemed to be related to higher temperature and precipitation in Jinju than those in Gongju during the experimental period. Initial C/N and C/P ratio of Q. acutissima leaf litter was 46.8 and 270.9, respectively. After 33 months elapsed, C/N and C/P ratios in Gongju decreased to 22.0 and 106.8, and those in Jinju decreased to 19.2 and 170.2, respectively. Initial concentration of N, P, K, Ca and Mg in Q. acutissima leaf litter was 8.31, 0.44, 4.18, 9.38, 1.37 mg/g, respectively. After 33 month elapsed, remaining N, P, K, Ca and Mg were 91.0, 85.4, 30.2, 47.9, 11.7% in Gongju, and 67.0, 54.2, 19.9, 30.0, 40.8% in Jinju, respectively. Except for Mg, remaining nutrients of decomposing leaf litter in Jinju were lower than those in Gongju. In case of N and P, initial immobilization was observed, however, only mineralization was observed in K, Ca and Mg during the whole experimental period.

  • In both elections of 1997 and 2001, Tony Blair of the Labour Party won #10 of Downing Street. This political success had to do with regionalism and was particular due to the devolution policy that was supported by non English citizens. However, there are negative voices about this policy which tries to cope with regional conflicts by decentralizing the central political power. The paper aims to examine the current regionalism movements and the devolution policy in Britain. For this purpose, the nation-building processes of the United Kingdom and various reactions to these processes, especially regional ethnic conflicts are discussed. And the study finally investigates the future perspectives of the devolution policy and its implications for both regionalism and the national-regional developments in Britain.

  • 충북지역의 C대학은 국립대 최초로 경영정보학과를 개설하여 20년 동안 관련 분야의 인재를 양성해 왔다. 하지만, 최근 학부제로 통합되어 운영되고, 기술기피 현상에 따른 전공 지원인력이 감소하고, 정보기술의 보편화로 경영정보의 정체성이 모호해지며, 국내외 경영교육 인증 실시로 인해 교과과정 재검토의 필요성이 제기되고, 지역 관련 업체에 진출하는 졸업생 수가 감소하게 되어 중장기적인 관점에서 학부과정 교과과정의 재검토를 실시하게 되었다. 관련 분야 실무종사자들을 대상으로 경영정보 분야의 지식수요를 파악하고, 재학생/졸업생 대상으로 교육서비스의 만족도를 분석하고, 국내외 전문가를 대상으로 자문을 받고, 경영교육 인증 관련 규정을 검토하는 등의 업무를 수행하여 교과과정 개편 기본방향을 설정하고, 교과과정과 교과운영방향을 제작하는 것을 목표로 작업을 수행하고 있다.

  • This study aims to explore practicable and sustainable strategies for locality documentation through networking, linking, and recontextualization of records in digital environments. It applies the 'spanDoc(SPAace-based Networked Documentation) Model to document Donghae-Nambu Railway areas placed in Busan Metropolitan City tentatively. Considering that mobility and openness are the main characteristics of Busan, railway areas and their stations can be proper places for representing such localities of the city. Moreover, there can be much experiences and memories of residents surrounding those areas, because Donghae-Nambu Railway has been used as short distance transportation facilities across the inner city of Busan since 1930's. This study tries to implement the documentation strategy for the selected space, following the procedures of the spanDoc Model. Firstly, this study develops the structure of the subjects through investigating the related information sources and archives from various collecting institutions. Secondly, it carries out records surveys to identify the essential records types for documenting the Donghae-Nambu Railway areas. Thirdly, it describes the subjects and sub-subjects, and the entries of places, people and subjects for adding to the dictionaries. Finally, it links many entities such as subjects, records, and dictionary, and builds the databases regarding the inter-links and systematic accumulation of the outputs of each step.

  • The aim of this study is to examine the development of social economy and institutional isomorphism in Chungnam Province. Although 'social economy enterprises' in Chungnam Province achieved rapid quantitative growth, public-led policy and institutional framework has intensified institutional isomorphism. Institutional isomorphism is a phenomenon in which all type of organization and activities become similar in an institutional environment. This isomorphism hinders the social value orientation and innovation of social economic enterprises. As a result of the case analysis, institutional isomorphization was intensified if regional ecosystem(that can maintain and strengthen social value orientation) was not established. The creation of social value is at a level that satisfies the institution and the social value orientation is also weakened.

  • The purpose of this study is to analyze widely how the higher education of China introduced market mechanism, adjusted and changed its structure, and what is its characteristic today. The market-orientedness of China's higher education has been strengthened as the direction of Chinese socialism was converted to the improvement of productivity and Socialist's Market Economy proceeded. It developed gradually from the experimental stage of the introduction of market economy, through its real introduction stage and the stage of strengthening of market-orientedness, and finally to the deepening and development stage. Through these processes, China's higher education has got the characteristic of market-orientedness. It is being improved for the strengthening of autonomy, privatization, and raising of competitiveness and has China's unique local trait.
