Purpose: The aim of this study was to identify differences and influencing factors in the level of life satisfaction among the urban community-dwelling elderly by age group. Methods: The study was conducted utilizing the secondary data of 2017 Seoul Survey in a cross-sectional design. Of 42,688 participants in total, the data of 7,927 adults aged 65 or older were analyzed. The data were analyzed using descriptive statistics, independent t-test, chi-square test, Pearson's correlation coefficients, and multiple linear regression. Results: There were significant differences between age groups, and it was found that the old elderly groups had significantly higher life satisfaction than the oldest elderly group (t=8.37, p<.011). In common, family and community factors influencing life satisfaction in the two age groups were companion animals (old elderly: β=.03, p=.002; oldest elderly: β=.06, p=.021), social network (old elderly: β=.10, p<.001; oldest elderly: β=.08, p=.008), and social support (old elderly: β=.05, p<.001; oldest elderly: β=.08, p=.005). Conclusion: Based on these results, social welfare and nursing care services focusing on social capital and age group-specific interventions are needed to improve life satisfaction of the elderly. This study might provide the possibility and evidence for a program to improve life satisfaction for the urban community-dwelling elderly, including social capital elements.

The multipurpose auditoriums in schools are the center of local community and the places of their life-long education. The multipurpose auditoriums are to be open and made available for use by local public as far as it does not interfere with the education of the schools. However, most of them are not open to public on the pretext of management problems while demands of local communities for the opening of the facility is rising. The role of the multipurpose auditorium as the place of physical training and its maximum availability to local community have be taken into account of from its design stage. The location of the auditorium itself has to be close to the main entrance of the school for easy access, its facilities located in one common area, their management and maintenance scheme adopted appropriately but legally, and then security and safety measurement have to be devised. Also, more studies are necessary to propose detail regulations for local sports facilities and to develop their interrelationship and network, in connection with sophistication of school facilities and BTL system.

Ecomuseums come into close relationship with resident and community. Progress of heritage concept brings on the change of valuation standard in heritage, that life style of residents become most important element of cultural heritage. The change of display method has caused the generation of various experience programs in ecomuseum which are display and education based on participation of visitors and residents. Ecomuseums in Europe during progress have conceptual peculiarities by themes to keep the cultural identity and protect folk culture in regional community. 'Europe Ecomuseum Network' seriously affected by social change and development is new alternative to promote regional identity and cultural exchange among Europe countries. People participation with all residents is decisive factor to promote identity and attachment in native place, as well as collaboration with residents, experts, administrators and NGO is one factor for sustainable development and the realization of ecomuseum, activation of regional economy, and also is the root of efforts to protect and activate regional community.

This paper is to research the difference of care workers' role in Sanatorium between urban and rural areas. Interviews have been conducted with 100 care managers with structured questionnaires in community care settings. The findings of the study are as follows. In the analysis of working with carers a care manager acting as a counsellor in rural was required rather more than any other role in working with clients' carers. In working with formal and informal networks, an administrative specialist role was also important in both areas. With resource management, there were some regional variances between rural and urban. In the urban area, a care managers as a coordinator was more required than as a broker. In the rural area, a care manager as a broker, selecting service resources for elderly clients was the most suitable role. In conclusion, in general rural care managers' roles were similar to those of many core managers in urban area. Among the many possible roles of care managers that effective continuity of care is to be provided for elderly clients in community care, two have been specified as essential roles. The first is the role of care managers that provides coordination and integration of services at the clients' levels as a care manager as an implementer, a linkman, counsellor. The second is at the system level which is possible role for coordination and linkage of programs as a characteristics of care managers, task with formal & informal network, community resources, available residential & NHS resourcesw.

Regional development and community design has become very important these days. Especially in Hyogo Prefecture after the Great Hanshin Awaji Earthquake, voluntary works have become more popular. With citizen participation, environmental circumstances change a lot. It is becoming very difficult for municipal governments alone to achieve every desirable project. NPOs made of professional members in the Hanshin area have conducted notable activities after the earthquake. At the same time it is necessary also to educate citizens for community design with greenery. These people will support their town design along with professionals. Awaji Landscape and Horticulture Planning Academy provides an excellent educational program, an introduction and examination of which should be valuable. The main concept of the education program is to foster the growth of local community design leaders. Students appreciated the programs very much even if initially they expected a more practical program about planting than programs that teach community design. Many people are active in their own towns to create better environments and communities. The network system "Alpha Green-Net" is functional to support graduates of the course. In the future these educational programs for citizens will becomes very important. Other cities are starting to have their own progrms, but they are still very short term. "Alpha Green-Net" is in the process of growing. Many members are very keen to develop their own abilities. In the future these NPOs should become independent. To help these NPOs become independent and active the educational programs should consider and teach about how to do this more in the future.

Herein, we explored the potential of the apple's core microbiota for biological control of Erwinia amylovora, which causes fire blight disease, and analyzed the structure of the apple's bacterial community across different tissues and seasons. Network analysis results showed distinct differences in bacterial community composition between the endosphere and rhizosphere of healthy apples, and eight taxa were identified as negatively correlated with E. amylovora, indicating their potential key role in a new control strategy against the pathogen. This study highlights the critical role of the apple's bacterial community in disease control and provides a new direction for future research in apple production. In addition, the findings suggest that using the composition of the apple's core taxa as a biological control strategy could be an effective alternative to traditional chemical control methods, which have been proven futile and environmentally harmful.

Federated learning (FL) is a ground breaking machine learning paradigm that allow smultiple participants to collaboratively train models in a cloud environment, all while maintaining the privacy of their raw data. This approach is in valuable in applications involving sensitive or geographically distributed data. However, one of the challenges in FL is dealing with heterogeneous and non-independent and identically distributed (non-IID) data across participants, which can result in suboptimal model performance compared to traditionalmachine learning methods. To tackle this, we introduce FedGCD, a novel FL algorithm that employs Graph Neural Network (GNN)-based community detection to enhance model convergence in federated settings. In our experiments, FedGCD consistently outperformed existing FL algorithms in various scenarios: for instance, in a non-IID environment, it achieved an accuracy of 0.9113, a precision of 0.8798,and an F1-Score of 0.8972. In a semi-IID setting, it demonstrated the highest accuracy at 0.9315 and an impressive F1-Score of 0.9312. We also introduce a new metric, nonIIDness, to quantitatively measure the degree of data heterogeneity. Our results indicate that FedGCD not only addresses the challenges of data heterogeneity and non-IIDness but also sets new benchmarks for FL algorithms. The community detection approach adopted in FedGCD has broader implications, suggesting that it could be adapted for other distributed machine learning scenarios, thereby improving model performance and convergence across a range of applications.

In this paper, I designed the satellite system, using the MF-TDMA (Multi Frequency-Time Division Multiple Access) DAMA (Demand-Assigned Multiple Access) method, that allocates the satellite resources more effectively to prevent a large quantity data discard when Earth Terminals (ETs) request their satellite network resource to Network Controller (NC) by using their history information, such as traffic pattern or traffic class which have been receiving, and the network controller allocates the satellite network resource and send to earth terminals by using his history information that earth terminals have been requested already. The U.S. Military Warfighter Information Network-Tactical (WIN-T) community has selected the L-3 Linkabit MF-TDMA DAMA Network Centric Waveform (NCW) as the networking standard for full-mesh IP over SHF satellite communications. In the MF-TDMA DAMA satellite network, network controller allocates the satellite network resources and enables maximum 255 earth terminals to communicate each other for periodic satellite network resource requests of earth terminals.
