This study considers the concept of schools and their spatial composition by John Dewey through literature review who argued for a new, children-centered education in the early 19th century, and it also mentions some suggestions for improvement of the elementary school facilities in Korea that the size and number of students in school has decreased sharply. John Dewey claimed that a school is a big household as well as a small society in which one studies the current occupation and experience in connection between the household-school-society. At the same time, he pursued an organic and open spatial composition which can effectively and efficiently enable educational curriculum's application, social occupation and project learning based on children's native impulse and stage in child growth. Korea's education policy should shift from quantity-based education production to quality-based production due to the reduction of school age population among other reasons. Especially this study emphasizes that small size schools need to be changed to local community facilities with environment-friendly, children-centered and open learning spatial composition with basis on John Dewey's educational philosophy.

The government has made a great effort for the development of rural area. The aim of this study is to analyze the change process and characteristics of the government's rural area development policies implemented so far and present an aid as adequate material to the direction of development policy for rural areas. The rural area development policy had been focused on maintenance of physical infrastructure facilities in the rural areas, pursuing urban convenience led by the government from the 1950s to 1990s. The policy has changed to local residents-led rural area development from the late 1990s to present time. The basic direction of the policy turned into making much of environment-friendliness and promotion of regional activation. The policy was transformed to recognize our rural area and also perceive it pastoral and resting space. In addition, green tourism has emerged as an important theme since 2000. In the rural area development policy, it is the most important to connect it with various development projects, select target areas from the long-term perspective and pursue efficiency through intensified investment of financial resources.

Noise problem that occurs in living environment is a big trouble in the economic, social and environmental aspects. In this paper, the filtered-X LMS algorithms, the adjoint LMS algorithms, and the robust adjoint LMS algorithms will be introduced for applications in active noise control(ANC). The filtered-X LMS algorithms is currently the most popular method for adapting a filter when the filter exits a transfer function in the error path. The adjoint LMS algorithms, that prefilter the error signals instead of divided reference signals in frequency band, is also used for adaptive filter algorithms to reduce the computational burden of multi-channel ANC systems such as the 3D space. To improve performance of the adjoint LMS ANC system, an off-line measured transfer function is connected parallel to the LMS filter. This parallel-fixed filter acts as a noise controller only when the LMS filter is abnormal condition. The superior performance of the proposed system was compared through simulation with the adjoint LMS ANC system when the adaptive filter is in normal and abnormal condition.

Purpose: The purpose of this qualitative study was to explore the transition experiences of the elderly from long-term care hospitals to their homes. Methods: The participants were eight elderly medicaid beneficiaries, who had been the subjects from the community care project in Korea. The data were collected with one-on-one interviews from April to November in 2020, and analyzed by phenomenological steps. Results: The seven themes derived in this study were 'Space to escape', 'Reliable supporter opened the way to discharge', 'Comfortable life at home', 'Obstacles to independent life', 'Struggling to live alone', 'Fence for community life', and 'Energizing in daily life' Conclusion: The results revealed the positive aspects of Community Care program in Korea. However, it is suggested that active communication between hospitals and community care institutions, and improvement of home environment to live in the community before discharge should be required. And system revision is needed to adjust activity in their home and support health problems of the elderly in the early stage of discharge. The results of this study can be referred to as the foundation of transitional care for the elderly.

The purpose of this study is to examine the status and limitations of the activation plan as a result of the change in urban regeneration paradigm. In particular, the change in housing life was considered following the guidelines of the New Deal project. Specifically, the three types - General Neighborhood, Housing Support, and DongneSaligi - were analyzed from the perspective of organization, space and program. In addition, the master plan and unit project, the organization and progress, and the budget plan were reviewed. As a result, the New Deal project for urban regeneration is importance on economic regeneration, which, unlike the integrated and continuous guide proposed by the government, could limit the individual progress of transitional organizations, 2-dimensional planing and various programs. Thus, first, in order to supplement the organization's verticality and inefficiency in progress, the annual business assessment should be discouraged and the permit and progress of the project should be determined at the local government level. Second, integrated and multidimensional planning is necessary to produce synergy effects in the physical environment. Finally, the link between program unit projects and the economic effects can be considered.
