  • Online communities, such as Internet portal sites and social media, have become popular since they allow users to share opinions and to obtain information anytime, anywhere. Accordingly, an increasing number of opinions are manipulated to the advantage of particular groups or individuals, and these opinions include falsified product reviews and political propaganda. Existing detection systems are built upon the characteristics of manipulated opinions for one particular time period. However, manipulation tactics change over time to evade detection systems and to more efficiently spread information, so detection systems should also evolve according to the changes. We therefore propose a system that helps observe and trace changes in manipulation tactics. This system classifies opinions into clusters that represent different tactics, and changes in these clusters reveal evolving tactics. We evaluated the system with over a million opinions collected during three election campaigns and found various changes in (i) the times when manipulations frequently occur, (ii) the methods to manipulate recommendation counts, and (iii) the use of multiple user IDs. We suggest that the operators of online communities perform regular audits with the proposed system to identify evolutions and to adjust detection systems.

  • The Korean government has been encouraging 'continuous' post-pump priming project management through relevant local personnel planning, action, and management, upon the selection of 68 sites for urban regeneration as part of the New Deal Project. This study assessed the utilization characteristics of containers, the socio-experimental temporary occupation facilities, as a tool for 'sustainable' urban regeneration. This is to identify the potential limitations of urban regeneration by the utilization of containers as public sector temporary occupation facilities and to provide adequate directions based on its efficacy. By comparing three Korean cases with the Japanese WaiWai project, in terms of 10 elements, the preoccupations with the social trend and scenery, and undifferentiated functions of the facilities focusing on the commercial or working aspects have been identified as limitations of Korean cases. Based on the analyses, the following are suggested as plausible approaches to utilize socio-experimental containers for sustainable urban regeneration: 1. Planning and management should be done by the same organization because the absence of the planning party's participation in the management likely leads to the pursuit of only profits. 2. Diversification and combinations of different utilization purposes of a single site and numerous planning of experimental container uses are in need. 3. Accommodations of heavy commercial uses lead to a decline in the continuity of follow-up projects and a change in the urban regeneration directions. Therefore, it is important to include a public socio-experimental program rather than a simple commercial or promotion program for the following urban renewal project.

  • A drastic development of modern cities and transportation means as part of a rapid industrialization and urbanization for the past half-century has consistently broaden the boundaries of urban dwellers while, at the same time, raising issues as to establishing relationships among them throughout the society following the materialization of modern urban planning. Within the framework of the postmodern concept, there have been consistent efforts to create a community space in appropriate size and, in particular, the concept of New Urbanism and Urban Village that emerged in mid 1800s along with the effort to build a community by building an ideal city provides an important meaning today when people are seeking to restore a healthy community. Against this backdrop, this study aims to explore the concept of community and to determine its optimal scope of implementation in the sense of healing environment under the premise that organizing a healthy city is based on building a solid urban community. The study findings and conclusions are as follows. First, a community is a subject of constant consideration in the process of historical development of the city and has required us to take a variety of strategic approaches and to determine the scope of implementation. Second, the activities of a healthy community have been conducted under various types of environments, including churches, commercial facilities, urban plazas, parks, and streets in various scales, reflecting their unique characteristics. Third, in the process of designing a healthy and sustainable city, determination of location carries significant implications along with building a community of appropriate size, which requires multidisciplinary considerations in addition to functional approaches. Fourth, the composition and design of a modern urban community need to seek practical ways of its implementation within the concept of healing environment.

  • The age of digital content mainstream consumers in the era of smart technology is expanding compared to the past. Consumers are taking a leading role in the production and distribution of contents in various forms. At the center of this is a post-modern social structure and space that break down the boundaries among Personal Digital Device, contents, production and consumption as a medium. Content rejects the existence of the same thing in the world. The tendency of the main consumer segment and the provision of post modern storytelling that penetrates it creates a huge industry group with various forms of contents. In order to carry out this study, with analyzing examples of movies, games, and advertisements, we found the fact that the center of content creation for individuals made their unique style, excluding generality. As a result of this research, the relationship between the user-driven digital contents and post modern storytelling have been revised the awareness about the possibility of various convergence in the field of contents production.

  • Surface data generally represent continuous distribution of geographical or social phenomena of a region in urban analysis. Instances include distribution of temperature, population of region, and various distributions related to human activities. When spatial data are given in the form of surface, surface comparison is required as a way of comprehending the surface change or the relationship between two surfaces. As for previous approaches of surface comparison, there are visualization, quantitative methods and qualitative method. All those approaches, however, show the difference between two surfaces in a limited way. Especially, they are not able to distinguish spatial difference between two surfaces. To overcome such problem, this paper proposes a method of comparing two surfaces in terms of their spatial structure. Main concept of the method comes from earth moving problem and the method is named minimum surface transformation, here. When a surface is transformed into another, total surface volume moved in the process of transformation should be the minimum. Both quantitative and spatial differences between two surfaces are evaluted by total surface volume moved and the distribution of moved surface volume of each cell respectively. The method is applied to hypothetical and actual data. From the former, it is understood that the method explains how two surfaces are quantitatively and spatially different. The result of the latter shows that moved total surface volume decreases as time goes by which fits the actual situation that population change rate gets smaller. Concerning the other measure of surface difference, the distribution of Xij describes detailed flow of surface volume than that of simply subtracting surface volume by indicating to what direction the population change occurs.

  • As Internet has become a popular media for sharing information, users create and share tremendous volume of information including large amount of personal information in cyberspace. Sharing private information online can enhance strength of social relationship but it could also bring negative consequences like information privacy invasion. Although many companies and governments address the importance of information privacy online, there are countless cases of crimes and hackings relating personal information online world wide. Since there are some researches investigating the role of governments and organizations on online privacy domain but there is little research regarding users' privacy protection behaviors. This study investigates relationship between Internet users' information privacy protection behavior and environmental factors. Especially, this study focuses on users' behaviors regarding information privacy protection technology adoption. According to our research results, users' online privacy protective behaviors positively affected by governmental regulations expressed as an information privacy protection law. In addition, if user is allowed to use anonymity when he or she uses online services, they have more tendencies to adopt privacy protection technologies. The detailed research findings and contribution are discussed as well.

  • 셀룰러 오토마타(Cellular Automata; CA)는 격자(cell)에 대해 사전 정의된 규칙을 바탕으로 이웃 격자 간 상호작용을 해석하여 복잡한 동력학적 현상을 효과적으로 재현할 수 있는 이산형(discrete) 모의 기법이다. CA 기법은 격자 구조에 수치표고 자료 및 토양수분 정보 등을 직접 매칭 후 상호관계를 해석하기 때문에 공간정보를 최대한 활용하여 불균질성을 나타내는 것이 가능하다. 따라서, 도시 유출해석에 있어서 높은 정확도와 빠른 계산속도를 기대할 수 있다. 본 연구에서는 CA 기반 고해상도 물순환·침수 연계 해석 framework 개발 방향 및 CA 기반 prototype 모형의 사면유출 적용 사례를 소개한다. 개발 중인 CA 모형에서는 격자별 침수 깊이, 침투, 토양수분 저류, 지표 유출 등의 물순환 요소를 모의할 수 있다. 기존의 집중형(lumped) 모형은 지표-지표하 유출에 대한 routing algorithm이 없고 각 셀의 물수지 모형 내 파라미터가 많은 단점이 있다. 따라서 개발 중인 CA 모형에서는 cell state 내 fast reservoir와 slow reservoir를 통해 지표-지표하 상태를 구현하고 단순화된 물수지 모형 및 흐름 방향 알고리즘을 적용함으로써 실제 현장에서 발생하는 다중 피크 형태의 지표 유출을 모사한다. 최적의 지표수 흐름 방향 알고리즘 선정을 위해 3개의 다중 흐름 방향 알고리즘(D4, D8, 4+4N)을 정량적으로 비교·분석한다. 이번 발표에서는 CA 모형을 소규모 산지 사면과 도심지 등 다양한 규모의 테스트베드에 적용하여 모형의 장단점을 평가한다.

  • Objectives: The purpose of this study was to examine the performances and limitations of health community building project of 148 village in Gangbuk-gu, Seoul on community health organization perspective. Methods: we conducted a qualitative study using both a systematic review of this project and in-depth interviews with the operators who had worked for the project from January 2012 to December 2012. Results: In this project, activists worked by gathering the opinions of the residents and focusing on their growth. The residents themselves established a community health care plan. Based on social determinants of health, they continued projects to solve residents' needs. A variety of programs were activated by providing a health cafe, which was an alternative public participation health promotion space that was not a clinic or a public health center. As the various entities gathered, there were difficulties related to interests and role sharing, and there were limitations such as the fact that the performance and limit of the pilot project could not be clearly predicted beforehand. Conclusions: This case suggested that new possibility of health and medical movement, approaching health issues by the way of community organization principle. Through the health community building project as community health organization perspective is expanded, health promotion effect will be created in the whole society.
