Underwater sensor network has attracted more and more attention from the networking research community recently. Most of traditional studies focus on the topology with a single gateway. Underwater sensor network consists of a variable number of sensors and multi-gateway to ensure the reliability of the network. In this paper, we propose a new MAC protocol that can reduce collisions among sensor nodes and improve QoS(Quality of Service) for underwater sensor network with multi-gateway. We evaluate the performance of the proposed scheme through simulation. Simulation results show that the proposed scheme outperforms the existing MAC protocol.

Purpose: This study analyzed research trends related to childhood and adolescent cancer survivors (CACS) using word co-occurrence network analysis on studies registered in the Korean Citation Index (KCI). Methods: This word co-occurrence network analysis study explored major research trends by constructing a network based on relationships between keywords (semantic morphemes) in the abstracts of published articles. Research articles published in the KCI over the past 10 years were collected using the Biblio Data Collector tool included in the NetMiner Program (version 4), using "cancer survivors", "adolescent", and "child" as the main search terms. After pre-processing, analyses were conducted on centrality (degree and eigenvector), cohesion (community), and topic modeling. Results: For centrality, the top 10 keywords included "treatment", "factor", "intervention", "group", "radiotherapy", "health", "risk", "measurement", "outcome", and "quality of life". In terms of cohesion and topic analysis, three categories were identified as the major research trends: "treatment and complications", "adaptation and support needs", and "management and quality of life". Conclusion: The keywords from the three main categories reflected interdisciplinary identification. Many studies on adaptation and support needs were identified in our analysis of nursing literature. Further research on managing and evaluating the quality of life among CACS must also be conducted.

This study aimed to develop program models for single households in the Healthy Families Support Centers. Data from seven female and seven male single households were collected through in-depth interviews. The major results were as follows. First, a demand for a program that both provides feeling safe and is self-caring came to the fore. Additionally, many respondents wanted to participate in programs with families. Second, the aspects of professional quality, diversity, and systematic management were mentioned as the strengths of programs in the Healthy Families Support Centers. Third, three program models were drawn up, as follows: The first model was a five-part program model like the current program settings of the Healthy Families Center. Those were sharing-caring, education, counselling, family-friendly culture, and community networking. The second model was a program for family relationships. The third was for joining programs with others. For the detailed program, a manual needs to be proposed, and the staff members who handle the programs for single households in the center will need to be retrained.

This study aims to investigate the characteristics of cyber communities composed of migrant workers from communities without propinquity in Korea. Its methods are both qualitative and quantitative. It further seeks to discover the relationship between the social capital formed and reproduced within these cyber communities and participants' cultural adaptation to Korean society. The study revealed that ethnic and non-ethnic communities differed in terms of strength of cohesion, space constraints, and links with the outside world. The former showed characteristics of a localized community type. The main motivations for migrant workers' participation in the ethnic cyber community were communication and friendship rather than cooperation and sharing among members. They usually used cyber communication media to communicate with one another. Conversely, the latter showed characteristics of an integrative type. Despite the difficulties in applying for membership and information provided in Korean, a high percentage of migrant workers participated in the community to obtain crucial information. The results did not show a significant correlation between social capital and migrant workers' traits within the cyber community, while a strong correlation emerged among four factors of social capital: faith, norms, networking, and political participation. The study showed that social capital in the cyber community was in direct proportion to an integrative type of cultural adaptation to Korean society. In particular, there was a strong connection between the cultural adaptation exhibited by members of the migrant subculture and their participation in discussions on political issues and human rights, with some migrants even functioning as agents of social change as participants in citizens' movements. The findings suggest that the cyber community facilitates the migrant subculture's communication with and integration into the indigenous Korean culture. Migrant workers' participation in the cyber community is therefore validated as an instrumental practice for members of this subculture to adapt to Korean society.

The purpose of this study is to suggest a successful operating strategy of co-working space. Therefore, the operating elements were identified through a literature research. And then, verified through site investigation and interview of operation managers. We found out that the high level operating elements are 'Co-working management', 'Membership management' and 'Supporting management' And the low level elements of Co-working management are 'Relationship facilitation', 'Networking event & Party' and 'Community & Communication', Membership management's are 'Service diversity & Price plan', 'Promotion & PR' and 'Alliance & Partnership', Supporting management's are 'Space & Interior', 'Facility & Device, Solution' and 'Mentoring & Education'. And the questionnaire was designed and conducted to Co-working space operators through the AHP method. As a result of the collected data analyzing, the highest priority was the operational element 'Community & Communication', and 'space and interior' is next, 'Service diversity & Price plan' is the third. The results were discussed with the relevant experts and it presents the following operating strategies. First, to create an environment suitable to voluntary coworking is the most important element. In particular, good management of 'Community & Communication' should be considered as a high priority operations strategy in a coworking space. Second, interior and space utilization helps in making the environment and atmosphere conducive to coworking. Office devices and facilities such as IT infra, printer, fax, scan, paper...etc are also important elements. But the reason why these necessary items are given a low priority is that these items don't need any special strategy. Third, in order to create a stable profit, 'Service diversity & Price plan' should be the characteristics of each coworking space because it will attract and secure enough customers. This study is valuable, it could be a great guideline for coworking space in an early stage to adopt operating model and strategy

This essay is a landscape of core values and relevant evidences about Creative Leadership in order to make sketches of Korean-style leadership framework. Glancing through this work, you can smell the distinctions of Korea creative leaders, particularly, in the aspects of procommunity pragmatism and ordinary innovation. Most Korea creative leaders were social mentors and masters who had enlarged their influences from the individual domain to social area in all the dimensions of human life. At the individual stage, the Creative Leadership suggests 'Jungki(正己)' as a core value of themselves, which is materialized as such competencies as self-assertiveness, observation and experimentation, and strong inquiry. Because most of them were technical masters dealing with new methodology and new knowledge including alchemy, medicine and weapons, the creative leaders show us very unique core values and competencies in the life sequences of the individuation, relationship, organization and community unlike other Korean-style leaderships and global practices. You can taste and compare these things: 'Kihyulsangtong(氣血相通)' as a core value and respect- for- others, style analysis, persuasion as core competencies in the stage of relationship, nextly, 'Suhshi(授時) & Jungeum(正音)' as a core value and coordination and adjustment, teamwork as core competencies in the stage of organization, finally, 'Hunmin(訓民) & Hwalin(活人)' as a core value and vision-building, social benefiting, ordinary innovation as core competencies in the stage of community. The value of this study is focused on the construction of Korean-style leadership framework based on the Creative Leadership through vivid stories about great leaders in our history.
