An Efficient Visualization Technique of Large-Scale Nodes Structure with Linked Information

Mun Su-Youl,Ha Seok-Wun The Korea Institute of Information and Commucation 2005 Journal of information and communication convergen Vol.3 No.1

This study is to suggest a visualization technique to display the relations of associated data in an optimal way when trying to display the whole data on a limited space by dealing with a large amount of data with linked information. For example, if you track an IP address through several steps and display the data on a screen, or if you visualize the human gene information on a 3-dimensional space, then it becomes even easier to understand the data flow in such cases. In order to simulate the technique given in this study, the given algorithm was applied to a large number of nodes made in a random fashion to optimize the data and we visually observed the result. According to the result, the technique given in this study is more efficient than any previous method in terms of visualization and utilizing space and allows to more easily understand the whole structure of a node because it consists of sub-groups.

This study introduces stakeholder grants which is a universal redistributive proposal based on the citizenship theory, and considers its feasibility in Korean society. Classical welfare states have focused on redistributive welfare policies, whereas modern societies focus on the need of somewhat different kinds of welfare policies from the traditional ones. The recipients of stakeholder grants will be young adults who are exposed to new social risk but have less provisions than other class, and they need more generous benefits and reversely discriminated in aging society. This study aims to enhance young adults’ equality and promote individual freedom. Furthermore, it aims to work towards the universal welfare state.

문수열(Su-Youl Mun),이창희(Chang-Heui Lee) 한국멀티미디어학회 2006 한국멀티미디어학회 학술발표논문집 Vol.2006 No.2

본 연구에서는 대학 강의실 관리의 전체 구조를 하나의 화면에 표시하여 시각적으로 관리가 가능한 시스템을 제안하고 구현하였다. 특히 대학에서와 같은 대규모 업무를 처리하고 그 결과를 제한된 화면상에서 효과적으로 보여주기 위해서는 시각화 기법(Visualization Techniques)을 적용한 화면 출력이 필수적이라 볼 수 있다. 제안하는 시스템은 인터넷상에서 사용이 가능하도록 담당자의 위치에 관계없이 강의실 관리가 가능하며, 대학의 강의실 운영 전체를 하나의 화면에 시각적으로 표현함으로써 현재의 강의실 사용현황과 사용하지 않는 빈 강의실의 개수와 위치 등의 파악이 가능하다.

지역사회복지관 수행사업에 대한 중요도-수행도 분석(IPA)에 관한 연구

문수열(Mun, Su-Youl) 한국지역사회복지학회 2015 한국지역사회복지학 Vol.0 No.53

본 연구는 지역사회복지관의 정체성을 확립하고 전문성을 강화하기 위한 목적으로 복지관 수행사업에 대하여 중요도-수행도 분석(IPA)을 실시 하였다. 결과분석의 도출을 위해 경남지역 지역사회복지관 6개 기관을 각 지역별로 임의표집한 후 1년 이상 근무한 사회복지사를 대상자로 선정하여 분석하였으며 분석결과는 다음과 같다. 첫째, 복지관에서 수행하는 사업의 중요도와 수행도 사이에는 전체적으로 유의미한 차이가 있으며(p < 0.05), 복지관 수행사업에 대한 중요도와 수행도 사이에는 어느 정도 격차가 있는 것으로 나타났다. 둘째, 사례발굴사업 외 13개 사업들은 구성원들이 중요하게 생각하고 실제 수행도도 비교적 잘 이루어지고 있어 적극 권장해야 할 사업이나 가족관계증진사업 외 10개 사업들은 중요도와 수행도가 낮은 사업군으로 중·장기적인 대책이 필요하다고 분석되었다. 셋째, 사업의 중요도와 수행도가 다른 이유로는 기관이 추구하는 가치와 실제 수행하는 사업 간에 인식차이가 있을 뿐만 아니라 사업의 중요도와 무관하게 예산 배정이 이루어지고 사회복지관 평가기준 항목과 사업의 중요도 사이에 격차가 그 원인으로 조사되었다. 이러한 결과를 중심으로 사업들의 우선순위와 권장하고 개선할 사업들을 도출하여 향후 사회복지관의 사업전략 및 방향설정에 필요한 기초자료를 제공하는데 기여하고자 한다. This study conducted an Importance Performance Analysis (IPA) of welfare center programs to establish the identity of community welfare centers and enhance their expertise. As a result, in order to draw results, six community welfare centers in the Gyeongnam region were randomly sampled by each area, social workers who had worked for over one year were selected for the analysis and the results of the analysis are as follows: First, overall, there was a significant difference between the importance and the performance of the welfare center programs (p < 0.05), and there was some gap between the importance and the performance of the welfare center programs. Second, there was an analysis that 13 businesses including a case discovery business were those that should actively be recommended, since the members attached importance to them and their actual performance was relatively good while mid- to long-term measures would be necessary for 10 businesses including the business for the promotion of family relations, since they were business groups with lower importance and performance. Third, as causes for the differences in the importance and performance of the businesses, it was investigated that there was a difference in awareness between the value the institution pursued and the actual programs because the allocation of the budget was made irrespective of the importance of businesses and there was a gap between the items of evaluation standards for the welfare centers and the importance of the businesses. Based on these results, this study attempts to draw the priorities of the businesses and those to be promoted and improved to contribute to providing base line data necessary for setting the business strategies and directions of welfare centers in the future.

Hypertext in the Internet browser provides necessary information easily and speedily, and also it has retrival functions. However, it's hard for beginners of this field to understand the structures and forms of hypertext. Therefore, this paper proposes that the hypertext compile HTML language, sort out functions, extract hyperlink in hypertext, and finally visualize the system of tree structure to 3-level. This method is efficient for systematic analysis oi hypertext. Also, it makes us understand easily hyperlink in hypertext, and it is possible to increase effective learning of visual presentation by using hyperlink.

본 연구는 영재교육 프로그램에 관한 국내 문헌 자료를 수집하여 메타분석을 실시함으로써 영재교육 프로그램 적용에 대한 효과성을 알아보고 이를 통하여 영재교육 연구에 대한 흐름을 정리하고, 새로운 연구를 위한 기초 자료를 제공하고자 한다. 연구대상인 77편의 논문을 코딩하여 총 425개의 효과 크기를 구하였다. 연구결과, 영재교육 프로그램이 창의성에 미치는 전체 평균 효과크기는 1.052로 나타났으며, 영재교육 프로그램 실시가 창의성에 36.4% 정도 사전-사후 대비 혹은 통제집단과 비교하여 효과적이었다. 창의성의 하위 요인별 효과 크기는 융통성, 독창성, 유창성 순서로 나타났으며, 학습자의 비인지적 요인에 미치는 효과크기 순서는 진로인식이나 리더십, 대인관계, 자아개념 순으로 나타났다. The purpose of this study to identify the effects of implementation of gifted education program on creativity by carrying out a systematic meta analysis based on collections of domestic literature, which is related to effects of gifted children education program at schools. Through this study it can be gotten a review of gifted education and given a bundle of basic data for another researchers. After coding 77 theses that were selected, a total of 425 effect sizes were obtained. The results of study are as follows. The total average effect size of the gifted children education programs on the creativity of gifted students was '1.052'. This means it has effect on creativity of elementary students by 36.4%, when considering the pre to post comparison. When looking into the effect size on each sub-factor of creativity, the largest effect size was occupied by flexibility followed in order by originality and fluency. Related with non-cognitive factors, the total average effect size of gifted education program appeared in which the recognition of career or leadership was the highest, followed by the improvement of interpersonal relations, and self-concept in order.
