The purpose of this study is to compare factors influencing the quality of life of osteoarthritis patients in urban and rural areas. The data were derived from the sixth Korea national health and nutrition examination survey in 2014 and analyzed using the IBM SPSS Statistics version 21.0 software package considering complex samples analysis. The subjects of study were 599 adults with osteoarthritis over 50 years. The results of the study show that the factors affecting the urban patients' quality of life are healthcare coverage types, knee joint pain, knee ankylosis, hip joint pain, low back pain, limited activities, and subjective health status. The rural patients' quality of life are influenced by knee joint pain, limited activities, and alcohol consumptions. Therefore, the government should create differentiating strategies and approaches, including community rehabilitation programs, to improve the quality of life of urban and rural patients with osteoarthritis.

This research explored contemporary cities and children's lives in picture books by a survey of 71 picture books published and translated into Korean from 1996 to 2006. These books represented city or urban life as their settings with children or personified animals as their main characters. They were classified by four categories. Results were the city space that most frequently appeared in the picture books were streets (73%) including downtown (38%) and back streets (6%). Emotions displayed by children in the city were mainly negative feelings (60%) including fear, worry, sadness, and boredom. The most important issue was alienation (28.5%). Main characters barely managed to cope with life in the city (76%).

This article examines spatial concepts of urban design led by Camillo Sitte (1843-1903) and its influences. Sitte infused the fervor of city planning as an initiator, and his achievements affected Adolf Loos (1870-1933). Thus, this thesis, with regard to Sitte's penchants concerning urban design, focuses on two matters in order to understand Camillo Sitte's efforts to invent a new method on modern city planning and its influence on an architect: first, it deals with his urban studies, theories, and practices on city planning that consider communal living and everyday life and urban typology as well; second, it discusses how his urban ideas are accepted by Adolf Loos. Conclusively, through the investigations on Sitte's movement on city planning and its influence on Adolf Loos, this study clarifies Sitte's efforts to improve urban life and its milieus, and then Loos's efforts to adopt Sitte's criticisms and then re-interpret them in tune with the modern way of living as well. As a result, this thesis shows that they suggested new methods in performing dialectic designs, drawing on the picturesque and modern tradition, although their difference is differentiated from the sense of space, exterior vs. interior, i.e. Raumkunst vs. Raumplan.

Purpose : This study was conducted to evaluate the effect of denture placement on nutrition status and quality of life in the urban elderly Material and method : The first survey was conducted from 45 targeted elderly people(25 experimental group, 20 control). In the first survey, information on general characteristics, chewing ability, food intake and nutrient intake, anthropometric measurement, and degree of satisfaction in life were obtained. The second survey was conducted to evaluate the effect of denture placement with same method as the first survey. Results : Before denture placement, there are no statistical significant differences (in general characteristics, chewing ability, nutrient intake, anthropometric measurement, and degree of satisfaction in life) between experimental group and control. But after denture placement, survey shows that there is statistically significant difference in chewing ability between two groups. The experimental group have higher intake of energy, protein, carbohydrate, iron, and vitamin C. in nutrient intake. And after denture replacement, there is significant improvement in degree of satisfaction in life. After denture placement there are significant changes in agitation and attitude toward own aging according to Lawton's factor classification. Conclusion: In short, this study shows that chewing ability improvement of the elderly has strong positive effects to their food intake, nutrient status and quality of life.

This paper evaluates and maps the quality of life in the Atlanta, Georgia metropolitan area in 2000. Three environmental variables from Landsat TM data, four socioeconomic variables from census data, and a hazard-related variable from toxic release inventory (TRI) database were integrated into a geographic information system (GIS) environment for the quality of life assessment. To solve the incompatibility problem in areal units among different data, the four socioeconomic variables aggregated by zonal units were spatially disaggregated into individual pixels. Principal components analysis (PCA) was employed to integrate and transform environmental, socioeconomic, and hazard-related variables into a resultant quality of life score for each pixel. Results indicate that the highest quality of life score was found around Sandy Springs, Roswell, Alphretta, and the northern parts of Fulton County along Georgia 400 whereas the lowest quality of life score was clustered around Smyma of Cobb County, the inner city of Atlanta, and Hartsfield-Jackson International Airport. The results also reveals that normalized difference vegetation index (NDVI) and relative risk from TRI facilities are two versatile indicators of environmental and socioeconomic quality of an urban area in the United States.

Urban transit is a large scaled complex system which combines rolling stocks, power supply, signal communications, tracks & stations etc. KRRI develops nine key devices since July, 2007 as a part of the second phase of project on the standardization of urban rail transit system, which include information-communication system, station facilities, AC-DC current electric power system in urban transit. We promote the project under two directions, i.e. user-customer oriented standardization and strategic standardization for leading technologies in urban transit. In this paper, we present development plan of these key systems in view of system life cycle based on system engineering standards KSX ISO/IEC 15288 which supplies the common fundamental frame to describe the life cycle of artificial systems. System engineering process of KSX ISO/IEC 15288 are helpful to efficiently develop those key devices, although it is difficult to apply the standard identically to the key devices with the varieties and characteristics.

Construction projects are vulnerable to diverse internal and external factors, requiring systematic and consistent performance management along the entire life cycle of a project. In particular, urban renewal projects have a range of performance measures, including policy reconciliation and permits, project development, project financing, design, construction, and occupancy and maintenance. This requires a program-level megaproject approach, which integrates each stage of a project as well as variety of stakeholders' interests in pursuing a project from different perspectives. However, previous research on performance management has focused especially on the limited scopes of factors, including cost, quality, and schedule at the project level or on financial factors at the firm level. Given the lack of current approaches, this study suggests an integrated and systematic performance management scheme to control urban renewal megaprojects at the broadened perspectives of the program level. To this end, this study adopts the balanced scorecard approach and elicits key performance indices associated with various project configurations. Finally, an algorithm is presented for quantitatively assessing the level of performances along whole life cycle of urban renewal megaprojects.

The characteristics of social and cultural life in agricultural regions in Korea encompass several positive external effects: quality of food services, awareness of environmental conservation, aesthetic enjoyment of nature and so on. The objectives of this study were (1) to measure the awareness among Korean youth of the benefits of rural life; (2) to delineate the differences between rural and urban youth; and (3) to promote an awareness of the importance of the social benefits of living in the country. To fulfill these purposes, a field survey method was used. The subjects were 211 third grade students from middle schools in rural and urban regions in Korea. The statistical methods used for this data included frequencies, percentages, 1-tests, etc. The study generatedconclusive findings about viewpoints toward the natural environment, urban and rural social culture, and perceptions of economic status. It showed significant differences between rural and urban youth's awareness of ideas such as'green field supply','labor power supply'and 'biodiversity conservation'.

Increased consensus among gerontologists exist on the need to pay greater attention to the reciprocal relationship between the social and spatial in order to understand the construction of aged identity and everyday lives of old people. With urbanization, spaces are increasingly age-graded and as a consequence, urban elders are socially isolated from the community. In this study, we examine the social interaction patterns in various places specifically designated for the elderly, such as the Senior Center, Senior Welfare Center, and Hall for the Aged in Seoul. Main purpose of this study is to understand everyday life experiences of space the elderly people residing in the city go through. Data were gathered through qualitative, case study method. Results show that such spaces were important sites for social interaction for urban elderly who lacked social spaces after retirement and active parenting role. Also, it was shown that each place presents different contexts for social interactions and certain components of social class differences existed. Heterogeneity within the participants of each place was also observed. Quite strong stereotypes about certain places were also observed among the urban elders. Based on these results, importance of developing a 'community perspective' in the study of old age is discussed.

It is very important that reduce the maintenance cost and extend life time of the urban transit EMU through effective maintenance method research. The maintenance cost of the urban transit EMU shares 70%$\sim$80% of it's life cycle cost. It means that the maintenance cost is bigger than the introduction cost of the urban transit EMU. In this study, we were survey and analysis for the reliability centered maintenance of internal and external many industry parts. Finally, we suggested the reliability/availability management System of the Urban Transit EMU' Maintenance.
