Constructing a reliable runoff model and reducing model runtime are important in research of real-time urban flood forecasting to reduce the repetitive flood damage. Sewer networks in the major urban basin such as Seoul are vast and complex so that it is not suitable for real-time urban flood forecasting. Therefore, the rainfall-runoff model should be simplified. However, the runoff results due to the simplification of sewer networks can vary depending on the subjectivity and simplification method of the researcher and there is a significant difference especially in 2-D inundation analysis. In this study, the sewer networks in various urban basins with different numbers and distributions of sewer networks were simplified to certain criteria. The accuracy of the simplification model according to the sewer network scale is evaluated by 2-D inundation analysis. The runoff models of Gwanak, Sillim, and Dorimcheon, frequently inundated basins were simplified based on four simplification ranges due to the cumulative drainage area set as a criterion for calculating the simplification range. This study will be expected that the inundation result of simplification models estimated through the analysis can contribute to the construction of a reasonable and accurate runoff model suitable for real-time flood forecasting.

The goal of this study is to suggest policy tasks for the public library in Seoul. For this goal, researcher compared macroscopically the gap between the Seoul city and the global competitiveness city using the core index of the public library, and analyzed microscopically the level of the Seoul city and the metropolitan cities and provinces focusing on the public library infrastructure and service index. Next, researcher evaluated the public library policies by linking the "2030 Seoul City Master Plan" and the "Library and Reading Culture Revitalization Plan". Based on the results, researcher proposed branding for global knowledge culture capitals, advancement of core competencies and systems of libraries, composition of citizen centered knowledge culture ecosystem, maximization of citizen's service satisfaction and expected benefits as future-oriented policy tasks of public libraries in Seoul.

This study examines the characteristics of population ageing and the employment of aged workers in Seoul. Population indexes such as aged/child ratio and longevity degree are analyzed to identify the time-spatial changes and differentiation of population ageing by Gu. Job offerers, job seekers and employees related to the aged workers are also analyzed using data from Center of Job Placement for the Aged in Seoul. The results indicate that population ageing of Seoul has progressed faster than other regions in recent years. In addition, regional differences in tendency of population ageing is obvious even within Seoul. The percentage of unskilled laborer is much higher in Seoul compared with other regions. There is geographical differentiation in employment of aged workers among regions within Seoul. The employment opportunity of the aged is high in core economic areas of Seoul, while low in the outer residential area. This shows geographical mismatch between job offerers and seekers, which means that it is difficult for aged workers to get the jobs near to their residence. Accordingly, governmental support and intervention is needed considering their lower mobility.

수돗물 불소화사업이란 치아우식증 (충치)을 예방할 목적으로 0.8ppm의 불소를 수돗물에 첨가하는 공중보건사업이며, 수돗물 불소화사업이 시행되지 않고 있는 서울시내 초등학교에서는 1995년부터 불화나트륨용액 (0.2%용액으로 매주 1회 또는 0.05%용액으로 매일 1회)으로 불소양치를 실시하고 있으며, 서울시 일부 보육시설에서는 만4세-6세의 취학전 아동을 대상으로 불소용액양치사업 (0.25% 용액)을 1997년부터 실시하고 있다. (중략)

대용량의 데이터를 시각적 요소를 활용하여 눈으로 볼 수 있도록 하는 데이터 시각화에 대한 관심이 꾸준히 증가하고 있다. 데이터 시각화는 데이터의 전처리를 거쳐 차원 축소를 하여 데이터의 분포를 시각적으로 확인할 수 있다. 공개된 데이터 셋은 캐글(kaggle), 아마존 AWS 데이터셋(Amazon AWS datasets), UC 얼바인 머신러닝 저장소(UC irvine machine learning repository)등 다양하다. 본 논문에서는 UCI의 화학 가스의 데이터셋을 이용하여 딥러닝을 이용하여 다양한 환경 및 조건에서의 학습을 통한 데이터분석 및 학습 결과가 좋을 경우와 그렇지 않을 경우의 마지막 레이어의 특징 벡터를 시각화하여 직관적인 결과를 확인 가능 하도록 하였다. 또한 다차원 입력 데이터를 시각화 함으로써 시각화 된 결과가 딥러닝의 학습결과와 연관이 있는지를 확인 한다.

In the context of region reconceptualized as a learning framework, using the Seoul region as an example, this paper focused on the debate and the condition of regional social studies curriculum in elementary schools, It means that regionalization of curriculum is the decentralization of power to develop and manage curriculum In that case, region is understood to he a resource used to connect the subject matter to children's experience, Furthermore, region is interpreted as Heimat, community and world around, Heimat is intended to be understood, loved and belonged to, Community is the resource for learning and the space of communication, participation and action, World around is the typical example to be searched, compared and explained by the concept and theory. On the base of the regionalization debate and the classification of learning a region, I analysed the local textbook, Social Studies Inquiry: Life in Seoul and suggested the framework of learning a region. In this paper, I tried to pick out the spatial demension of Seoul. It is classified into the space of experience, participation and inquiry, In conclusion, the region-specific materials and approach laying stress on the issue and topic in the geographical context of the region will determine that a proper regionalization occurs through not only methods hut also content.

The purpose of this study was to analysis a satisfaction about technical specialized high school supported by Seoul metropolitan office of education. The study was carried out through questionnaire survey method. The population sample for the study constituted 894 completed questionnaires from sample of 1050 technical specialized high school students and parents. A survey questionnaire for students consisted of 20 scales, and it for parents consisted of 16 scales. Both descriptive and inferential statistics were employed for data analysis. Major findings of this study were as follows: First, satisfaction perceived technical specialized high school students supported by Seoul metropolitan office of education was high. In sub-variables of school satisfaction, 'school facilities' was the highest, and 'relation to teacher' was the lowest. Second, three related variables were found to be significant in affecting the satisfaction of technical specialized high school students supported by Seoul metropolitan office of education. They were grade of students, achievement of students, and school type(public school/private school). Third, their parents were satisfied with technical specialized high school supported by Seoul metropolitan office of education. Fourth, gender difference of parents and school type(public school/private school) had no appreciable affect on satisfaction of parents.
