This study was performed to determine the levels of quality of life(QOL) according to the grade of long-term care service in the elderly people who were judged from long-term care insurance, and to reveal its association with related variables. The interviews were made to 958 elderlies in urban and rural areas from March 1 to May 31, 2009. The mean scores of QOL among all subjects were $55.4{\pm}15.62$(Grade I; $49.7{\pm}14.17$, Grade II; $56.8{\pm}14.62$, Grade III; $59.4{\pm}16.36$), and they were lower according to the higher grade of long-term care insurance. The multiple regression analysis was used to reveal the explanatory powers of factors influencing on the level QOL. Such factors as educational level, monthly income, subjective health status, depression and MMSE-K were shown to affect their QOL in Grade I, Grade II, and Grade III with explanatory powers of 45~62%.

Improved estimates of populations at risk for quick and effective response to natural and man-made disasters require spatial disaggregation of zonal population data because of the spatial mismatch problem in areal units between census and impact zones. This paper implements a dasymetric surface model to facilitate spatial disaggregation of the population of a census block group into populations associated with each constituent pixel and evaluates the performance of the surface-based spatial disaggregation model visually and statistically. The surface-based spatial disaggregation model employed geographic information systems (GIS) to enable dasymetric interpolation to be guided by satellite-derived land use and land cover data as additional information about the geographic distributor of population. In the spatial disaggregation, percent cover based empirical sampling and areal weighting techniques were used to objectively determine dasymetric weights for each grid cell. The dasymetric population surface for the Atlanta metropolitan area was generated by the surface-based spatial disaggregation model. The accuracy of the dasymetric population surface was tested on census counts using the root mean square error (RMSE) and an adjusted RMSE. The errors related to each census track and block group were also visualized by percent error maps. Results indicate that the dasymetric population surface provides high-precision estimates of populations as well as the detailed spatial distribution of population within census block groups. The results also demonstrate that the population surface largely tends to overestimate or underestimate population for both the rural and forested and the urban core areas.

This paper was performed to comparative study with the children's body strength status of Ethnic Korean in China and Korea. The subjects of this study were the students of each elementary school located in a rural and a urban areas in China. To compared the level of their body strength status, we investigated to the students of 2 elementary schools as comparatives group on Kojae Area in Korea. We used students' physical record in the school. The contents of the study were the body weight, the chest circumstance, and the body height of the subjects. To make out the level of the students' physique, we measured by Rohrer Index output through above body height and body weight of them. The results of this study were as follows; 1. In the case of Ethnic Korean in China, the average body weight(kilogram) is $28.94{\pm}6.68$ in male $28.51{\pm}7.58$ in female. Comparatively, the average body weight in the case of Korean is 31. $99{\pm}7.23$ in male and $31.74{\pm}7.82$ in female. The average body height of Ethnic Korean is inferior about 2-5 Kilograms to that of Korean. 2. The average chest circumstance (centimeter) is $63.51{\pm}5.21$ in male $63.05{\pm}5.87$ in female of Ethnic Korean, $65.54{\pm}6.43$ in male and $64.57{\pm}7.81$ in female of Korean. Compared to between two group, the average chest circumstance of Ethnic Korean is inferior about 2-4 centimeters to that of Korean. 3. The average body height (centimeter) of Ethnic Korean is $135.28{\pm}8.96$ in male $134.82{\pm}9.74$ in female, and that of Korean is $136.68{\pm}9.12$ in male and $136.10{\pm}9.92$ in female. Like the preceding below results, the average body height of Ethnic Korean is inferior about 2-5 centimeters to that of Korean. 4. Compared to the fullness degree of physique between two group using Rohrer Index, Ethnic Korean is thiner than Korean. 5. Temporary, in case of children from 10 to 12 years old, female is superior to male through the index contained of the body weight, the chest circumstance, and the body height. It seems that female and male had different maximum growth age.

This study aims to investigate the hierarchical stepwise migration and its influences on regions (metropolitan areas, cities and counties of Korea administrative district) through analyzing the city rank-size and the changes of natural increase of population. The result shows that the inter-regional migration has been associated to the decrease of the population and the decline of NIR in the regions where outflows have been persisted. Also, theses demographic events have sequentially occurred through the hierarchy of settlement system: gradually from rural (gun) and lower ranked regions in the system of city rank-size, to urban (si) and regions in the high ranks in the system. Based on the result of this study, it is possible to understand and expect the major origins of inter-regional migration, the presence of the hierarchical stepwise migration and most significantly, the spatial expansion of depopulation problems.

The human history has progressed closely related to land. Mankind started land administration as a tool of governance to make land the object of imposing taxation as well as developing the land administration as a concept of securing property rights. People have drawn boundary lines on the ground to form a land parcel according to the usage and/or ownership. Furthermore, the land administration has been developed as a registering system of cadastral records fer the public announcement of fixed boundary instead of changeable ground boundary. Currently the citizens demand the provision of accurate and diverse information on the land which is assessed to has high property value encouraged by the rapid development in the post-industrial society today. However, even though the fact that the Korean cadastral registers produced during the Land Investigation Project are still practically in use causes land-related disputes and promotes public mistrust because of the changed boundaries by parcel mutation, the expansion and contraction of map sheets and the quality deterioration and damage of map paper, but the ultimate resolution is not yet made so far. The distance difference between boundary points are compared and analyzed using TS surveying method in the research as a methodology to resolve the boundary inconsistency, the current problem of cadastral records. Consequently, I'd say that the new surveying method of registering the coordinates of real ground boundary has been regarded as more efficient than considering the matter on the map regardless of urban or rural areas.

The purpose of this study is to analyze the geographical location information data and the damage trends according to the type of landform for the study of various cultural properties in 44 traditional places with national designated cultural properties damaged by the racing earthquake on September 12, 2016. The landform type was the most enclosed type, and the location type was more frequent in the surrounding area, such as urban and rural areas. The waterside type was located along rivers, rivers, valleys, lakes, and oceans except for the top of the mountain, but this area was found to be vulnerable to earthquakes, It is understood that it should be referred from cultural property management the side. 26 of the total 44 were temples. The elevation and slope increased with increasing of the flat type, the background type, the enclosed type, the mountain type, and the top type. Most often located on 1-20 % slopes, with the slope facing south more often than not. Within the 10 km range from the epicenter, 23% were concentrated, within the range of nearly 65 km, the background type was closest, and was concentrated in the northeast and southwest from the epicenter. In this study, it is meaningful to analyze earthquake damage in various aspects from the viewpoint of traditional space which is a landscaping cultural property and it will be used for planning, designing and managing traditional spaces.

As a population of leisure activities grows and diversifies, there is a great demand for portable and environment-friendly power generation systems. A small wind power generation system is emerging as a suitable power generation equipment to meet these needs. The most important thing when developing a small portable wind turbine is to reduce the weight of the generator and increase the efficiency. The existing 300W wind turbine generator weighs about 10kg, which is heavy to carry. Therefore, a new generator weighing less than 4kg to make it easy to carry with high efficiency has been developed. In addition, considering complicated characteristics of wind volume and topography of Korea, a small wind turbine that can be used in urban and rural areas individually was constructed. Through basic designing and optimization, the lightweight and efficient generator was manufactured. It is a 300W wind turbine designed and fabricated with reduced weight as a prototype. The average output voltage of the generator was 24.7V at 900rpm no-load test. On a load test with the average line voltage 36.8V and the average phase current 2.62A, when the mechanical input was 339.84W, an average voltage output of the generator was measured as 289.5W with efficiency of 85.18%. The generator weight was 3.84kg.

Objectives: This study aimed to identify the vaccination rate for pneumococcus among aged 65 or older, and at the same time to determine the reasons for vaccination or non-vaccination. Methods: The population of this study was aged 65 or older, with a total of 1,150 subjects to be analyzed and a computer assisted telephone interviewing was used. The survey included pneumococcal vaccination status, reasons of vaccination, sources of information on vaccination, reasons for not vaccination, and other related factors. Results: The vaccination rate for pneumococcus among aged 65 or older was 56.2 percent, lower than 69.0 percent in the U.S. (2017), and 69.2 percent in the U.K. (2019). Among the factors related to the pneumococcal vaccination, the groups with the high vaccination rate were women, low age groups, residents of urban areas, people without a job, people with high education, medical insurance subscribers, married people, and people who have family members. In addition, the groups with high vaccination rates were those with high awareness, those who received recommendations from doctors, those who had vaccination records, those who believed in vaccination effects, and those who saw public service advertisements. Conclusions: In the future, it is necessary to develop alternatives to accurately manage vaccination records for adults who are not eligible for state support, and regular adult vaccination rates should be calculated so that they can be used as evidence for the country's infection control policy.

The purpose of this study is to investigate the effect of social capital on Goendang(relatives) culture, which is a traditional local community culture, and local development as a positive factor. In order to evaluate the effect of social capital, a survey targeting 600 Jeju residents was conducted and 594 returned questionnaires were interpreted for the final analysis. Descriptive analysis, T-test, ANOVA analysis, and multiple regression analysis were conducted on the collected data, using SPSS 18.0. As a result, firstly, the levels of social capital of the surveyed appear as follows: network (average score 4.01), trust (average score 3.80), norms (average score 3.43), cooperation (average score 3.00), and participation (average score 2.80). Secondly, there are differences in social capital among the surveyed groups based on urban-rural areas, administrative districts, and average monthly income. Finally, among the dimensions of social capital, as the relative importance of network and participation increases, the surveyed think that they need Goendang culture more. Also, i t turns out that as the relative importance of norms and participation increases, Goendang culture can exert influence on local development as an important influence factor. Therefore, based on the analysis, this study shows that nurturing social capital can allow people to utilize Goendang culture for local development as a positive community culture.
