Because of rapid aging, housing stability of elderly household is becoming an important social problem. The population of the elderly people was 11.3% and that of the elderly household was 23.2%, about 407 million, in 2010. Yet, social policies for elderly people are focusing on the household who takes care of the elderly people, not on the elderly headed households. These policies fail to reflect the reality. Housing satisfaction of the elderly household is different based on the tenure type and the satisfaction can be further affected by the types of elderly household within the same tenure group. Thus, strengthening the policies for the elderly headed households as well as differentiating the policies based on the types of household is required in order to meet the needs of the elderly households. For the elderly household living in a rent house in a city, a housing voucher is needed and for the low income elders who own their houses, housing renovation is required. Public housing affects only the residential satisfaction of single elderly households, not for all elderly households probably because public housing does not meet the demand of the elderly households appropriately. Since the elderly households wanting to move is noticeably small, a policy that provides proper facilities within the elders' neighborhood is most necessary. Also, in order to lessen the burden of housing expenses of the elders with low income, a public housing policy, in which 2-3 people living together in one public housing, needs to be examined.

In this study, seismic performance was evaluated considering the deterioration level for the low-rise and moderate buildings with non-seismic details which are most common in Korea. Evaluation results showed that the deterioration condition is relatively good even after 24 years of construction but the seismic performance did not satisfy the protection index in the first and second evaluation. In case of the third evaluation, the goal performance was satisfied based on the interstory drift ratio but reinforcement is found to be necessary. Seismic performance was evaluated after the target buildings were reinforced in the walls, bracing, and damper. Results showed the interstory drift ratio drastically reduced regardless of reinforcement methods and satisfied the level of immediate occupancy. In case of wall reinforcement, however, base shear increased more than double which requires review on the existing foundation.

This study performed factor analysis for 21 independent variables related to the effect of illumination and suggested the effect by multiple regression analysis on the relationship between the effect of illumination and the satisfaction of use of a dependent variable to find the effect of illumination in urban parks at night and the effect of illumination on the satisfaction of use. The results of this study are as follows; 1) Of the 21 independent variables used to study the effect of illumination in urban parks at night, the impact on safety and possibility of crime was highly. The effects of illumination by factor analysis were abstracted as effects of removing anxiety, securing safety, increasing use. 2) As a result of multiple regression analysis, independent variables influencing satisfaction of use in urban park were proved as effects of removing anxiety, securing safety, increasing identity, preparing atmosphere and increasing use. Also, the effect of securing safety was the most important factor; it showed a level of importance 2 times higher than the effect of removing anxiety, and 7.7 times higher than the effect of preparing atmosphere in relative contribution of the effect of illumination to satisfaction of use. 3) Of the effects of illumination influencing satisfaction of use in urban parks, the effect of securing safety and the effect of increasing visibility were more significant than the effects of removing anxiety, preparing atmosphere and increasing use. This fact means that personal safety an the identity of persons or facilities in the space of use should be considered with priority in planning or designing illumination. Also, it implies hat, for night use in urban parks, lightness of the space is required for general safety of use at parks, and proper illuminance on the activity in the space of use should be required. The subject parks of this study are 8 urban neighborhood parks. The model on the effect of illumination and the satisfaction of use depends on characteristics and conditions of location of he park and user class, so the subject parks and persons should be varied, and the difference by sex or ages should be suggested.

Nowadays, interest in health care is increasing due to Coronavirus (COVID-19), and a lot of people are doing home training as there are more difficulties in using fitness centers and public facilities that are used together. In this paper, we propose a personalized exercise recommendation algorithm using personalized propensity information to provide more accurate and meaningful exercise recommendation to home training users. Thus, we classify the data according to the criteria for obesity with a k-nearest neighbor algorithm using personal information that can represent individuals, such as eating habits information and physical conditions. Furthermore, we differentiate the exercise dataset by the level of exercise activities. Based on the neighborhood information of each dataset, we provide personalized exercise recommendations to users through a dimensionality reduction algorithm (SVD) among model-based collaborative filtering methods. Therefore, we can solve the problem of data sparsity and scalability of memory-based collaborative filtering recommendation techniques and we verify the accuracy and performance of the proposed algorithms.

Recently, parking problems have repeatedly occurred not only in the residential areas of the old town, but in detached residential areas, neighborhood living facilities, and commercial areas of the planned New Town. This study suggests a strategy to minimize parking problems before constructing a New Town by reviewing these parking problems at the new city district planning stage. Parking problems can be divided into supply-demand and non-supply-based, and the solution strategy is reviewed in terms of supply and operation. The procedure for applying the solution strategy is proposed according to the effectiveness and ease of application.First, this paper suggests the PAZ (Parking Analysis Zone) as the basic analysis unit. Second, the supply-based parking problem in the concerned area based on the land use plan of Hanam Gyosan is reviewed. Last, solutions to a parking problem for each PAZ are presented.

This study is a development plan of a resort in a regional center that aims to generate tourism consumptions that have ripple effects on the regional economy by developing abandoned mine complexes in Daechon. Thanks to economic growth, the public awareness of tourism has changed. Hence, want for tourism influences development and advancement of recreational spaces, combining with various cultural contents. Development associated with environmental issues caused by modernization has become a major issue. At this point, to rediscover and specialize industrial complexes of bygone days as tourism resources signifies regeneration of regional resources. This study aims to find a solution for appropriate tourism development as part of the measures to revitalize the regional economy in underdeveloped areas and to improve the polluted environment. The result of the study is summarized as follows: First, in regional development alongside the development of a resort complex, it is important to construct environmental similarities. Minimizing differences in landscape structures is especially necessary because it will cause tourism resources in a regional center to be naturally linked to regional activities. These will then be recognized as attractions in the neighborhood. Therefore, it is desirable to reflect a spatial structure for environmental convergence, and, at the same time, to fulfill operation purposes by space through differentiation of movement lines. Second, in utilization of existing environmental resources, it is desirable to express localities and to develop differentiated elements. Facilities should not be homogenized, attaching importance to trends. Therefore, in establishing a development plan, it is important to have an attitude to accept existing roles and functions in a transformative manner. Third, recreational facilities in resort spaces generally have the problems of being uniformly planned as part of a development project and being limited to landscape facilities. Introduction of specialized facilities that can be reconciled with the regional environment and that can be open influences the landscape structure of the entire region and brings ripple effects as key facilities for activation of tourism.
This research aims to investigate the cause of the occurrence of a weak road drainage section scientifically and specifically through a site survey for a poorly drained section occurring due to rainfalls during road operation. This paper deeply reviewed the existing research results and current situation data on the poorly drained sections accumulated in Korea Expressway Corporation in order to investigate the cause of the occurrence of a weak road drainage section, and deeply verified and analyzed the weak sections for the road surface drainage facilities and the other road drainage facilities by visiting the expressway controlled by the 6 local headquarters and 33 branches of Korea Expressway Corporation. As a result of site surveys for the weak road drainage sections, i) in a road surface section, occurrence of ponding in the road shoulder pavement due to slope changes, bad collection of water in the collecting well at a median strip, shortage of road shoulder dike height, and inferior construction, etc. was analyzed to be the main cause of the occurrence of poorly drained sections, and ii) in a road neighborhood section, the occurrence of pavement height difference in a main road and shoulder section due to inferior ditches on a slope and the bad drain age at the inlet and outlet of a culvert due to soil deposits, debris, etc. were analyzed to be the main cause of the occurrence of weak sections. Proposed as a plan to improve the poorly drainage section of road were i)calculation of capacity through material changes at the ditch, enhancement of vertical sections and hydraulic analysis in terms of construction and other aspects, ii)derivation of a combined slope considering a slope and a vertical linearity and maintenance of proper distance between drainage structures in a vertical concave section in terms of geometrical structure, and iii)calculation of the drainage facility installation interval using a minutely rainfall intensity formula and a non-uniform flow analysis technique in terms of hydraulics and hydrologics and prompt removal of rainfalls from the road surface according to a linear drainage method.

Among city parks, children's parks are more accessible than other parks in the city, and there are many users. They are used not only for children's playgrounds, but also for relaxation and leisure spaces for local residents. On the other hand, as a result of focusing on the quantitative increase by the engineering division by the Urban park Act, the consideration of the users of various classes is insufficient. The purpose of this study was to analyze the actual use of children parks in single - family housing and communal housing areas, and to identify the problems and future directions of the use of children parks. For this purpose, a case study and a document survey were conducted. First, through scholarship research, the theoretical review and the present situation were summarized based on the data, such as the papers and research reports related to the existing children's park. The status of the location, facilities and management were then identified through interviews and site visits with the children's park management staff. As a result, the children's park was utilized as a leisure space with high accessibility in the living area. As a result, the residence time of most users was within 1 hour to 2 hours. In particular, use by elderly people was higher than the use by children. Therefore, it would be desirable to design the future planning of the children's parks and to plan the arrangement in accordance with the future - oriented multi - purpose neighborhood type children's park.
