The objective of this study was to evaluate the community's capacity and hindrance factors affecting the community's activities by exploring the process of restoring the community's environmental pollution. This study examined the community activities related to the restoration of pollution that occurred at the former Janghang smelter in Seocheon-gun. The results of this study showed that leaders, cooperative resources, and the media were elements positively influencing the recovery of the community. The starting point that became the driving force for community activities was the presence of a leader who had a small stake in it. Moreover, it required cooperation such as the continuous interest of local active groups and residents to continue this effort. Above all, the media publicized the incident and amplified the activities of members. Meanwhile, there were various conflicts hindering the activities of local communities in the process of restoring the pollution such as the internal conflicts of community groups, conflicts between residents and active groups, and conflicts with the government. The behaviors that appeared in the process of restoring the pollution revealed a form of united governance. Moreover, they changed from an initial "supportive" character to "resistant" and "defensive" activities. Later, it was transformed into "subjective" and "creative" activities.

This study focused on the role of active knowledge seeking (knowledge browsing and knowledge searching) in the context of virtual community of interest. Knowledge seeking is rarely studied as an antecedent in knowledge management (KM) research. Active knowledge seeking is considered as antecedents of sense of virtual community which mediates to knowledge sharing intention and virtual community promotion. Research hypotheses are tested by applying structure equation modeling with survey data from virtual community members in South Korea. Active knowledge seeking behavior was found to be the strong predictor of sense of virtual community, which, in turn, positively affects knowledge sharing intention and virtual community promotion. Implication to practitioners is to understand and accommodate the members' knowledge seeking efforts, who are potential contributors and promoters of the virtual community. Knowledge seeking, knowledge sharing and promoting virtual community are more of human activities than technology and this study extends the understanding of such human activities. By providing a mechanism of how knowledge seeking and sharing could work harmoniously, a virtuous circle with win-win situation could be achieved in virtual communities.

This study aimed to investigate teacher learning in the context of a community. For the purpose of this study, two research questions about the kinds of teacher noticing in a community and the role of partnership were addressed. To build a learning community, a professional development project, PRIME, established partnerships with 11 high schools and one of the cluster meetings were investigated in this study. Three mentor teachers, three preservice teachers, and one university supervisor participated in the cluster meeting. For this study, the multiple data such as audio tapes of cluster meetings, observation notes, and interviews were analyzed using the analysis of narratives. The results showed that the participants engaged in different kinds of noticing of their own beliefs about teaching and learning, teacher practices, and teacher identities including noticing of students' understanding in classroom situations. The partnership played the crucial role of reinforcing relationships among teachers, assigning tasks, and creating various communities.

The aim of this article is to explore the neighbourhood plan in the UK on the basis of the characteristic of community partnership. In establishing the plan in the UK, a characteristic of public partnership is that a local community takes part in the whole process of establishing the plan. In addition, the central and local government induce the participation of such communities while establishing a statutory duty. To conduct the duty, the government introduce a referendum in the process of the establishment of the plan while emphasizing that the majority selection is the best solution. Based upon this local partnership, one of important lessons from the case of the UK is that in terms of local development, the evolutionary pathway to the social economy become one of more crucial factors beyond the economy itself. In addition, this pathway is deeply concerned with the community partnership.

This study aimed to examine the mediating effects of social withdrawal between adolescents' mobile phone dependence and the sense of community, and to secure the evidence data for adolescents' mobile phone dependence intervention. Among the 7th year data for the 4th grade students in the Korean Children & Youth Panel Survey(KCYPS), 1,979 students were included. The results showed that mobile phone dependence had a significant effect on the decrease in the sense of community and influenced the sense of community through social withdrawal. These results imply that positive intervention to reduce social withdrawal is needed and it can improve the sense of community in youth. Also, when we deal with weakening in the sense of community, we should consider convergent intervention in psychological and social aspects which deal with dependency, social withdrawal, and the sense of community.

The current study seeks to understand the multi-faceted desires of language learners through the theoretical lens of imagined communities (Norton, 2001). Particularly, the study focuses on the learners of Korean language-one of the less commonly taught languages in the U.S. that has received relatively less attention in previous literature on second language motivation. The study analyzed and compared the narratives told by eleven Korean language learners in a post-secondary language program, and identified four types of imagined communities: Communities of K-pop Culture, Communities of Professionals, Communities of Korean Family and Relatives, and Communities of ethnic Koreans. The study found that these imagined communities were not restricted to a specific region or an ethnic group but encompassed various populations connected through the use of Korean language. The study also found variability within what has been readily labelled as heritage motivation (or motivation related to heritage), as well as striking differences between heritage language learners and non-heritage language learners in terms of their scope of imagination.

The purpose of this study was to explore ways to revitalize the community-based child care community by identifying the factors that are hindering and activating the operation and use of this community by elementary school students. To this end, an in-depth interview survey was conducted of operators of child care communities in Jeollabuk-do and users of caring communities. Detailed themes, sub-ranges and upper ranges were determined through a qualitative research method. As a result of the study, it was determined that the basic environmental weakness of the caring community and its lack of power are the things hindering the operation and use of rhe communities the most. On the other hand, the main activation factors for community-based child care community activities were the stabilization of the environment and the strengthening of the internal capacity of the care community. This study is meaningful as basic data for the safe establishment and activation of a community-based child care community, which is emerging as an alternative to the child care gap due to the prolonged effects of COVID-19.

This study is aimed at understanding the wisdom of our ancestors in Korean traditional villages and finding out cues to designate and utilize community space in planning residential area in villages by examining community space in Korean traditional villages from cultural landscape point of view. This study designated 18 Korean traditional villages which have been preserving Korean traditional culture up to now, so deserve conservation from historical, cultural and artistic viewpoint. This study divided community spaces in each village into social area and ritual area depending on their uses and functions based on the results of pilot study and main study. In addition, ritual areas were also divided into Confucian ritual area and ethnic ritual area. Specifically, this study examined characteristics of space location and users by understanding the location of community space factors in the 18 villages. As for the factor analysis of community spaces, community factors established after the modern age were examined from modern viewpoint, and factors which had been destroyed or lost their original functions were examined from retrospective viewpoint. In conclusion, this study found out that cultural landscape in Korean traditional villages were affected by social relationship among villagers. The community spaces of villagers were multiple-function space rather than a space which was exclusively used by a specific class. Though the occupation of these spaces was separated and differentiated depending on sexes and ages, villagers tried to understand and respect each other through tacit communication.

A supercavitating vehicle has a speed of more than 300 km/h in water. A numerical analysis of the flow around a supercavitating vehicle must deal with a multiphase flow consisting of the water, vapor and exhaust gas because the vehicle is powered by roket propulsion. The effect of the exhaust gas on the vehicle is an important part in the study of the performance of the supercavitating vehicle. In the present study, the effect of the exhaust gas on the drag of vehicle was investigated by conducting numerical analysis. When there is no exhaust gas, drag of vehicle is affected by re-entrant. In the case with rocket propulsion, the exhaust gas reduces the influence of re-entrant. The exhaust gas also creates Mach disk and it changes drag profile.
