Based on 'Backpack-free day' and 'Unsupervised studying day' in the early 1980s, 10% of all schools in 2004 had at least 1 day of five-day classes a month as at least 2 days were enforced in 2006, and most elementary and middle schools had widely enforced the five-day class since 2012 March. The five-day class system expands the stage of studying from school to families and local societies to build an educational community related to school-family-local societies to provide various activities such as culture, art, sports, social, nature experiences on holidays to have the goal to foster creative future talents with proper personality understanding and considering others. In Busan, the five-day week class of Saturday program is being operated in various methods by national local government and public organizations. The Saturday program of local societies registered in the Saturday school of the information sharing networks are 2823 in total for the past 6 years which are being operated by national local government and public organizations. However, participation of students in the Saturday program is around 20% in 2012 March when Saturday holiday system was widely conducted. For this, problems in the Saturday programs that are currently being enforced are to be closely analyzed and participation expansion plans are to be made. Therefore, this study analyzes and investigates operation forms of Saturday programs conducted in Busan to propose an improvement plan to fulfill goals of Saturday programs and boost participation of students.

This study aims to explore how journalistic norms are practiced in journalists tweets by analyzing journalists' twitter. The study found that journalists consider using twitter as an extension of journalistic practice rather than a private space. In other words, journalists use twitter without a clear distinction about the nature of the twitter. In terms of journalistic norms, journalists expressed actively their opinion rather than keeping the traditional notion of objectivity. There are not much tendency of sharing the gatekeeping role. Also, journalistic use of twitter does not increase transparency as much as expected. However, there is a positive sign of practicing the newly expected journalistic role, conversation with news users. Finally the relationships between journalistic use of twitter and journalistic norms are not straightforward but diverse depending on the size and type of press, and gender of journalists.

Knowledge ecosystem means a dynamic knowledge circulation, including knowledge creation, exchange and sharing and utilization. It is also the field of knowledge practice, which creates interactions in knowledge exchange between people and groups. The key premises of knowledge ecosystem, based on the nature of general ecosystems, can be characterized as follows: first, it primarily focuses on social networks between people and organizations participating in the process of knowledge circulation; secondly, knowledge ecosystem thrives on diversity of knowledge; and thirdly, it is significant for selection of valuable knowledge and adoption of appropriate knowledge. This review attempts to make a systematic examination of a wide range of existing studies on knowledge ecosystem. In so doing, it is expected to provide a basis for further inquiry into more critical and complicated issues. Although the scarcity of existing research-at least those in Korea-may limit the implications of findings, this review offers a set of suggestions for future research.

This paper presents a case of community participatory neighborhood park design. The site, Yangji park, is located in Sandang-dong, Dongjak-gu, Seoul and the area is about 1,870m. Neighborhood park is defined as an outdoor space which is close to people´s home and is considered to be their own, because of the residents´ collective responsibility, family association, and frequent shared use. It is a place for pleasant rest area for community, sharing a sense of nature and retaining a sense of tradition and culture which is disappearing in a city. It is related to the daily life of the people near the site and becomes a place to let the community increase dialogue and understanding between people. On the other hand, participatory design is a design in which people participate in the design process. Thus people can understand the project well, present their opinions better, and reconcile conflicts between the different interests of people. This design applied a community participatory design method to design a neighborhood park. The major strategies for participatory design were ´workshop´, ´card game´, ´walking site´, ´interview´, and ´questionnaire´. Eight workshops were performed for the participation design. The major spaces and facilities elected by participants were the ´main entrance plaza´, ´entrance symbol space´, ´children´s ´playground´, ´multipurpose sport ground´, ´grass land´, ´foot-pressure area´, ´spaces symbolizing a rock mountain and an old well´, ´space for youth´, ´a pavilion´, etc. From this selection, design concept alternatives were generated by participants. The aster plan was developed from these design alternatives with the help of landscape architects. It was revised by ist visits and community discussions. People were also involved in the construction process and left their own works, such as hand prints, on the site. After construction, residents continued to maintain the park by themselves. As a result, It was found that participatory design was very effective for people´s satisfaction and sustainable park management. By involving people more in the process they developed a sense of community, a sense of ownership, and attachment to the place. In conclusion, it is suggested that we need to develop an effective people´s participation method to Korean society.

The traditional approach of fixed spectrum allocation to licensed networks has resulted in spectrum underutilisation. Cognitive radio technology is envisioned as a promising solution that can be used to resolve the ineffectiveness of the fixed spectrum allocation policy by accessing the underutilised spectrum of existing technologies opportunistically. The implementation of cognitive radio networks (CRNs) faces distinct challenges due to the fact that two systems (i.e., cognitive radio (CR) and primary users (PUs)) with conflicting interests interact with each other. Specially, in self-organised systems such as ad-hoc CRNs (AHCRNs), the coordination of spectrum access introduces challenges to researchers due to rapid utilisation changes in the available spectrum, as well as the multi-hop nature of ad-hoc networks, which creates additional challenges in the analysis of resource allocation (e.g., power control, channel and rate allocation). Instead, game theory has been adopted as a powerful mathematical tool in analysing and modelling the interaction processes of AHCRNs. In this survey, we first review the most fundamental concepts and architectures of CRNs and AHCRNs. We then introduce the concepts of game theory, utility function, Nash equilibrium and pricing techniques. Finally, we survey the recent literature on the game theoretic analysis of AHCRNs, highlighting its applicability to the physical layer PHY, the MAC layer and the network layer.

Ecological and ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to minimize disturbance caused by human activities. An ecological information portal can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. In this study, we designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for diverse classes of stakeholders. To reach the goal, we had reviewed related and comparable ecological database portals to design conceptual structure of EcoBank system including database management framework. Then, we developed some functions of ecosystem analysis for each stake-holders (researchers, general public and policy makers). As a result of this study, we successfully designed of EcoBank system covering the functions of Digital Object Identifier(DOI) publishing and data quality management process. Also, we (1) applied ecological indices for calculating biodiversity by administrative boundary for policy makers, (2) provided statistical information of econature map for general public and distribution characteristics of species for researchers. To make a successful establishment of EcoBank, we have to collect and build up related database and offer various and reliable ecological data consistently. We expect that the successful construction of EcoBank will help not only to accomplish sustainable development goals but also to raise the welfare of ecosystem in Korea.

Objectives: This study aims to investigate the married female immigrants' experience on Korean dietary life adaptation, especially identifying the symbolic meaning and nature of experiences. Methods: This study was conducted with six married female immigrants through an analysis of the qualitative materials which consisted of in-depth interviews, field notes and materials. Data was analyzed using Giorgi's phenomenological research methods. Results: The results were deduced as 116 significant statements, 17 formulated meanings (sub-theme), and 6 theme clusters. Six theme clusters comprised of lack of preliminary knowledge and information, conflict and support in relationships, Korean food culture which is different from homeland, adaptation attitudes of Korean food culture according to situation, sharing of homeland food culture, and practical difficulty and expectative service. The participants started Korean life in the dark about Korea and Korean food culture, so they were subjected to trial and error. The conflict between Korean mother-in-law and foreign daughter-in-law came from lack of consideration of daughter-in-law's cultural background. Some participants were hurt because of misunderstanding and nitpicking. They were learning about cooking method, ingredient, seasoning, table setting and manner. Some participants integrated Korean food culture and their homeland food culture. Some of them assimilated with Korean food culture. One of them maintained homeland food culture. The participants who adapted Korean food culture well could share homeland food amicably. They sometimes didn't apply the services which were offered by the government, because the services did not fit their needs. Some of them didn't know the usage route of the services or information. They had resistance about home teaching and it showed that outreach service was not always effective. Conclusions: This study suggested that it is necessary to develop a practical support plan which covers married female immigrants' real needs and system improvement measures.

'Video Commerce' has grown significantly, and is in the era of so-called V-commerce 2.0. Based on this background, this study focused on the link and the possibility of creating synergy between V-commerce 2.0 content and MCN, and examined the linkage strategy considering its characteristics. In conclusion, first, V-Commerce has evolved into the age of 2.0, centered on the characteristics of content that are oriented towards fun and sympathy, beyond the 1.0 era. Second, V-commerce 2.0 content has the characteristic of replacing the sharing and recommendation based on the nature of SNS networks as promotion and purchase enhancement. Therefore, competitiveness as 'content' is relatively important before 'commerce'. Third, V-commerce 2.0 and MCN industry have a strong connection with each other in terms of securing core competitiveness and creating a new profit model. In order to create the synergy between V-Commerce 2.0 and MCN, we proposed the use of big data to reinforce V-Commerce 2.0 customized content competitiveness, building of storytelling marketing and branding, and enhancement of live performance and interactive communication.

As a substitute for preventing school violence, the reward and punishment system has some problems such as different imposition basis for each teacher, ambiguity of applicable items, and difficulties in directing students in relation to parents of students. In this thesis, a reward and punishment points management system is implemented based on the web to solve the problems. The week point of the current system is complemented by separating the system into four parts, operating each part that is operated by administrators, teachers, students and their parents respectively and sharing their data. In addition, as each group of administrators, teachers, students and their parents is organically connected to the system, when special problems occur, the problems can be solved effectively. Therefore, if the implemented system is used in the field, the guidance of human nature is naturally conducted by understanding broadly for student's living guidance. Furthermore, it can be helpful to prevent students from school violence in advance.
