This study aims to analyze space planning of accommodations in seven closed schools involved in experiential activity programs on Jeju Island, a famous tourist destination in Korea. The results are as follows. First, 35 schools had been closed down in Jeju between 1982 and 2015. Among them, four closed schools were sold, three are currently used by the Jeju special self-government provincial office of education, and 25 are being leased by individuals, village organizations, and other entities. However, they have not been well-operated, and so strategies for the effective management or operation of these closed schools should be developed. Second, there are distinctive differences in space planning of accommodations based on the correlation between experiential activities and the types of participants. If the experiential activity participants are mainly individuals or small groups, the closed school is likely to plan double-bed accommodations and individual bathrooms rather than large group rooms. Third, in order to operate experiential activity programs, closed schools require four different spaces for experiential activities, lodging, dining, and sanitation. The largest space available in each school building is used for experiential activities, and original classrooms are still in use. According to the standard drawing of school architecture, standard classroom size since 1997 has been $7.5{\times}9$ meters, and lodging rooms have mainly been re-planned based on the module of the standard-sized classroom. School cafeterias are utilized as dinning and kitchen spaces. For sanitation purposes, original school restrooms are still used by experiential program participants, while the shower rooms are newly equipped.

Public library is established on impartial accessibility of any distinction as their sex, age, financial status, etc. The function of public library is not only to accumulate materials and offer information but also minimize gulf between the rich and the poor by knowledge possession, which is realized by important means to intercept exclusive possession and power in knowledge pose-industrial society. As it is judged that most public library is established to individual building with thousands of cost, it is judged of obstacles to Increase library buildings. The purpose of this study is try to find the way to Increase In number of public library In Seoul by interaction local education-cultural facilities. The result from this study, the user rate of public library is influenced by number of buildings and accessibility of traffic and public library can improve efficiency by substantial operation by basic function for all age group. The target population of Seoul public library sizes by decuple of advanced countries because of difficulty of accessibility, so it needs to make it small scale and also can offer self-regulation learning, materials and life-long learning programs because generally public library's utilization purpose is different by age. As school in Seoul amounts to 25 times of public library by about 1,200 buildings and can function of lifelong education center with a school library, cultural center and other composition buildings, so school facilities may use as a public library for local residents.

This study verifies the effectiveness of developing and implementing a leadership educational program specifically customized to improve of leadership competencies among members of multicultural family support centers and healthy family support centers. This program refers to Triangle Leadership that consists of three categories: finding individual strengths and self-esteem to enhance self-leadership, constructing a vision and roadmap to develop transformational leadership, and stress and teamwork management for competent servant leadership. In order to improve its completeness, focus group interview was adopted for 10 employees in the center and supervised by two professionals. The program was also conducted twice for 142 members of multicultural family support centers and healthy family support centers across the Korea. The result of implementation (with regard to the satisfaction level for the contents of the program) showed that both first and second rounds had improvement in all three categories compared to what was expected before taking the education program. The level of satisfaction for instructor and program operation was more enhanced (as well for the second time) compared to the first round. The evidence of program effectiveness indicates that there is a high anticipation for another approach that suits for the circumstances and requirement of centers and facilitator training.

Objectives: This study was conducted to investigate the current status and to suggest future directions for health management of teenagers who use healthy school tuck shops to improve teenagers' eating habits while reducing and preventing obesity. Methods: A total of 29 students (16 middle school students and 13 high school students) took part in the interview for this study, and the interview was conducted for each school's focus group by using qualitative research methodology. Results: The current status of using healthy school tuck shops and suggested future directions were divided into two categories. Personal barriers such as discrepancies between personal perceptions and behaviors and lack of food choice suitable to individual tastes can be solved by rebuilding the operating system to provide intuitive promotion of behavior and customized products through improvements in existing products and new product development. A lack of consistent management from low utilization convenience and difficulty in maintaining a constant purchase price can be handled by establishing a solution to restricted physical access for products, as well as seeking profit by improving distribution costs via continuous cooperation between the school and community. Conclusions: Continuous funding and a system that reflects the needs and preferences of healthy school tuck shop users should be applied for sustainable operation of healthy school tuck shops to improve teenagers' eating habits.

Engineering structures in operation essentially belong to time-varying or nonlinear structures and the resultant response signals are usually non-stationary. For such time-varying structures, it is of great importance to extract time-dependent dynamic parameters from non-stationary response signals, which benefits structural health monitoring, safety assessment and vibration control. However, various traditional signal processing methods are unable to extract the embedded meaningful information. As a newly developed technique, variational mode decomposition (VMD) shows its superiority on signal decomposition, however, it still suffers two main problems. The foremost problem is that the number of modal components is required to be defined in advance. Another problem needs to be addressed is that VMD cannot effectively separate non-stationary signals composed of closely spaced or overlapped modes. As such, a new method named generalized adaptive variational modal decomposition (GAVMD) is proposed. In this new method, the number of component signals is adaptively estimated by an index of mean frequency, while the generalized demodulation algorithm is introduced to yield a generalized VMD that can decompose mode overlapped signals successfully. After that, synchrosqueezing wavelet transform (SWT) is applied to extract instantaneous frequencies (IFs) of the decomposed mono-component signals. To verify the validity and accuracy of the proposed method, three numerical examples and a steel cable with time-varying tension force are investigated. The results demonstrate that the proposed GAVMD method can decompose the multi-component signal with overlapped modes well and its combination with SWT enables a successful IF extraction of each individual component.

This study is to understand the entrepreneurship of youth and entrepreneurship education of youth, to examine the characteristics of entrepreneurship education of youth between South Korea and United States. And entrepreneurship is also the process of creating a new organization, which is understood as a process by an individual and a group of entrepreneurs who possess qualities and abilities with social opportunities, and move them into action and practice. There is a need for a comprehensive entrepreneurial mentality training and execution center for youth. To discussion social changes between South Korea and United States. The United States uses Junior Achievement ASK model. In contrast, South Korea through systematic and proactive education development, but due to the lack of standard founding education content. Therefore, it presented the need for professional institutions for comprehensive entrepreneurship education and operation. Korea is not well organized with the lack of standard start-up education contents, so it is urgent to develop and distribute education actively. Although the United States has been leading education at the national level, foundations are conducting education more actively.

As knowledge is paid attention as a new production factor that generates added value, studies continue to apply knowledge management to business environment. In addition, as ICT (Information Communication Technology) was engrafted in business environment, it leads to increasing task efficiency and productivity of individual workers. Accordingly, the way that a business achieves its goal has changed to one in which its individual members are willing to take part in the organization and share information to create new values (Han, 2003) and studies for the system and service to support such transition are carrying out. Of late, a new concept called 'Enterprise 2.0' newly appears. It is the extension of Wen 2.0 and its technology, which focus on participation, sharing and openness, to the work environment of a business (Jung, 2013). Enterprise 2.0 is being used as a collaborative tool to prop up individual creativity and group brain power by combining Web 2.0 technologies such as blog, Wiki, RSS and tag with business software (McAfee, 2006). As Tweeter gets popular, Enterprise Microblog (EMB), which is an example of Enterprise 2.0 for business, has been developed as equivalent to Tweeter in business circle and SaaS (Software as a Service) such as Yammer was introduced The studies of EMB mainly focus on demonstrating its usability in terms of intra-firm communication and knowledge management. However existing studies lean too much towards large-sized companies and certain departments, rather than a company as a whole. Therefore, few studies have been conducted on small and medium-sized companies that have difficulty preparing separate resources and supplying exclusive workforce to introduce knowledge management. In this respect, the present study placed its analytic focus on small-sized companies actually equipped with EMB to know how they use it. And, based on the findings, this study examined their knowledge management strategies for EMB from the point of codification and personalization. Hypothesis -"as a company grows, it shifts EMB strategy from codification to personalization'- was established on the basis of reviewing precedent studies and literature. To demonstrate the hypothesis, this study analyzed the usage of EMB by small companies that have used it from foundation. For case study, the duration of the use was divided into 2 spans and longitudinal analysis was employed to examine the contents of the blogs. Using the key findings of the analysis, this study is aimed to propose practical implications for the operation of knowledge management of small-sized company and the suitable application of knowledge management system for operation Knowledge Management Strategy can be classified by codification strategy and personalization strategy (Hansen et. al., 1999), and how to manage the two strategies were always studied. Also, current studies regarding the knowledge management strategy were targeted mostly for major companies, resulting in lack of studies in how it can be applied on SMEs. This research, with the knowledge management strategy suited for SMEs, sets an Enterprise Microblog (EMB), and with the EMB applied on SMEs' Knowledge Management Strategy, it is reviewed on the perspective of SMEs' Codification and Personalization Strategies. Through the advanced research regarding Knowledge Management Strategy and EMB, the hypothesis is set that "Depending on the development of the company, the main application of EMB alters from Codification Strategy to Personalization Strategy". To check the hypothesis, SME that have used the EMB called 'Yammer' was analyzed from the date of their foundation until today. The case study has implemented longitudinal analysis which divides the period when the EMBs were used into three stages and analyzes the contents. As the result of the study, this suggests a substantial implication regarding the application of Knowledge Management Strategy and its Knowledge Management System that is suitable for SME.

The purpose of this study are as follows : First, This study conceptually provide an insight of reasons that organizations seek to create, acquire, store and distribute knowledge at the level of an organization and of process how they can transform or evolve to knowledge based organizations. Second, this study confirms examine what theories can be used to knowledge management, how such theories can be useful to analyse knowledge management and provide a theoretical foundation for knowledge management research. Applied to the theories of knowledge based and resource based view and institutional theory, the essence of knowledge management confirms that the organization finds job-related knowledge and know-how retained by individual of organizational members systematically and shares common knowledge within the organization and explains knowledge creation, multi-dimensional knowledge transition and share in all dimension of individual, group, and organization. As a result of comparative analysis of theory of organizational knowledge creation theory, In knowledge management, building of knowledge-creative culture, transitional process of explicit knowledge and tacit knowledge, knowledge creation and knowledge operation are important. In the basis on these study results, we discussed how the organizational knowledge creation theory can be used to manage knowledge in the organization, and also proposed hypotheses based on some arguments against the universal acceptance of the theory.

Recently, uncertainty in predicting available water resources is gradually increasing due to climate change and extreme weather conditions. Social interest in water management such as flood and drought prevention is also increasing, and after the unification of water management implemented in 2018, domestic water management is facing a major turning point. As part of such strengthening of water management capabilities, various studies are being conducted to utilize a hydropower dam for flood control and water supply purposes, which was mainly operated for hydroelectric power generation. However, since the dam evaluation methods developed based on a multi-purpose dam are being applied to hydropower dams, an additional evaluation approach that can consider the characteristics of hydropower dams is required. In this study, a new water supply capacity evaluation method is presented in consideration of the operational characteristics of hydropower dams in terms of water supply, and a connected reservoir simulation method is proposed to evaluate the comprehensive water supply capacity of a dam group operating in a river basin. The presented method was applied to the hydropower dams located in the Bukhan River basin, and the results of the water supply yield of individual dams and multi-reservoir systems were compared and analyzed. In the future, the role of hydropower dams for water supply during drought is expected to become more important, and this study can be used for sustainable domestic water management research using hydropower dams.
