In order to determine temporal changes of the urban landscape, interdependence and interaction among geo-spatial objects can be analyzed using GIS analytic methods. In this study, to investigate changes in the landscape structure of the Namyangju area, the size and shape of landscape patches, and the distance between the patches were analyzed with the Spatial Autocorrelation Method. In addition, both global and local spatial autocorrelation analyses were conducted. The results of global Moran's I revealed that both patch size and shape index transformed to a more dispersed pattern over time. Next, the local Moran's I of patch size in all time series determined that almost all patches were of a high-low pattern. Meanwhile, the local Moran's I of the shape index was found to have changed from a high-high pattern to a high-low pattern in time series. Finally, as time passes, the number of hot spot patches about size and shape index had been decreased according to the results of hot spot analysis. These changes appeared around the development projects in the study area. From the results of this study, degradation of landscape patches in Namyangju were ascertained and their specific areas were delineated. Such results can be used as useful data in selecting areas for conservation and for preparing plans and strategies in environmental restoration.

The purpose of this study is to approach for the flow analysis of changing central-place functions and basic demands between the central city and the small town. Under the rural society progressed, this study examines how the small town changes in the relation to the central city. The subject of study is based on changes in demand for retail and hospitality. The small town is providing basic demands and urban services primary for the rural in the settlement system. Because of the rural depopulation and the aging of society, Retail and hospitality in the rural is reducing of the facility followed. But the majority of related researches are stocks approach. These studies are useful to find out the characteristic of small town, but is difficult to consider the influence of the central city. In this situation after this study using the function index is set up a concept model, it examines for the basis of changes in demand for the small town. The result of the analysis is that the changes of retail and hospitality are more severe in the more small town than in the central city. Whereas the small town with a population decline is consistent with the reduced number of branches, Population growth in the central city is reduced to the number of the Number of branches. The central-place function has been strengthened in the central city. While the younger generation, recreation, etc. related retail are disappearing rapidly, the mainstream of small town is grocery, home improvement, restaurants.

Remote sensing cannot provide a direct measurement of vegetation index (VI) but it can provide a reasonably good estimate of vegetation index, defined as the ratio of satellite bands. The monitoring of vegetation in nearby urban regions is made difficult by the low spatial resolution and temporal resolution image captures. In this study, enhancing spatial resolution method is adapted as to improve a low spatial resolution. Recent studies have successfully estimated normalized difference vegetation index (NDVI) using improved resolution method such as from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard EOS Terra satellite. Image enhancing spatial resolution is an important tool in remote sensing, as many Earth observation satellites provide both high-resolution and low-resolution multi-spectral images. Examples of enhancement of a MODIS multi-spectral image and a MODIS NDVI image of Cheongju using a Landsat TM high-resolution multi-spectral image are presented. The results are compared with that of the IHS technique is presented for enhancing spatial resolution of multi-spectral bands using a higher resolution data set. To provide a continuous monitoring capability for NDVI, in situ measurements of NDVI from paddy field was carried out in 2004 for comparison with remotely sensed MODIS data. We compare and discuss NDVI estimates from MODIS sensors and in-situ spectroradiometer data over Ochang plain region. These results indicate that the MODIS NDVI is underestimated by approximately 50%.

Background and purpose : Stroke is a leading cause of death in Korea. Early measures to prevent stroke are extremely important since it has no cure. Korean might have different risk factors since their dietary habits and socio-economical status differ from most western countries. However, the risk factors for stroke in Korea have not yet been identified. Moreover, the lifestyle of healthy Korean adults has not been investigated. In this study we investigate the lifestyle of healthy adults living in Seoul and rural areas and compare the lifestyles of the two. Methods : One hundred seventy one subjects were studied. Among the subjects studied, 128 were from Seoul, the other 43 were from the country area. The age of the subjects was limited to over 40 years. Blood pressure, fast blood sugar, and cholesterol were measured. The subjects' height, weight, body mass index, total body fat, skinfolds thickness of triceps, subscapular and abdomen were measured to determine obesity. Using a structured interview, we assessed : sodium intake, physical activity and exercise, consumption of vegetables, fat, fish and fruits. The results of the two groups were compared. Results : There were no statistical differences in age and education between the two groups of subjects. The mean age of the subjects were 66 years old. The subjects residing in rural areas had a higher intake of sodium(p<0.05), lower physical activity(P<0.05), and higher BMI and body fat (p<0.05) as compared to the subjects in Seoul. Subjects with hypertension were between 24% and 33% and the prevalence of hypertension was the highest when compared to the prevalence of DM or hypercholesterolemia. However, the prevalence of hypertension, DM, hypercholesterolemia, were not significantly different in these areas. Conclusion : Our results show that subjects living in rural areas eat more salty food, exercise less, and tend to be obese. The finding of this study lead to speculation that Korean living in rural areas have less information about the effects of diet on health than city dwellers do. General health and nutrition education programs aimed at the prevention of stroke and other such conditions for rural area Koreans may close the risk factor gap between rural and urban dwellers.

Purpose: to investigate the relationship of between socioeconomic characteristics, and weight perception and lifestyle on body mass index (BMI) in Korea. Method: Participants were 2,405 people recruited from the 2007 Fourth Korea National Health and Nutrition Examination Surveys. Data included weight perception, BMI, and lifestyle factors and was analyzed using ${\chi}$ 2-test, logistic regression Results: Perception of weight was significantly different according to gender, age, education and residence. In the obesity group 21.6% perceived their weight as normal whereas 29.6% of the normal group perceived their weight as obese. In the obesity group, men who were over 70 years old, rural residents and only had elementary education perceived their weight range as normal. In the normal weight group, women who were urban residents and university graduates more frequently perceived their weight as obese. Logistic regression analysis of lifestyle factors, indicated that misperceived obesity was associated with walking (OR=0.703, 95% CI=0.553-0.896), weight control (OR=2.693, 95% CI=2.080-3.485), and health exam (OR=0.730, 95% CI=0.567-0.940) whereas misperceived normal weight was associated with walking (OR=0.696, 95% CI=0.497-0.975), weight control (OR=0.523, 95% CI=0.363-0.749). Conclusion: Results indicate differences in self-perceived weight and life style and provide information that can be used for health promotion program development.

The problem of the population number of honeybees that is decreasing not only domestically but also globally, has a great influence on human beings and the entire ecosystem. The habitat of honeybees is recognized to be superior in urban environment rather than rural environment, and predicting for habitat assessment and conservation is necessary. Based on this, we targeted Cheonan City and neighboring administrative areas where the distribution of agricultural areas, urban areas, and forest areas is displayed equally. In order to predict the habitat preferred by honeybees, we apply the Maxent model what based on the presence information of the species. We also selected 10 environmental variables expected to influence honeybees habitat environment through literature survey. As a result of constructing the species distribution model using the Maxent model, 71.7% of the training data were shown on the AUC(Area Under Cover) basis, and it was be confirmed with an area of 20.73% in the whole target area, based on the 50% probability of presence of honeybees. It was confirmed that the contribution of the variable has influence on land covering, distance from the forest, altitude, aspect. Based on this, the possibility of honeybee's habitat characteristics were confirmed to be higher in wetland environment, in agricultural land, close to forest and lower elevation, southeast and west. The prediction of these habitat environments has significance as a lead research that presents the habitat of honeybees with high conservation value of ecosystems in terms of urban space, and it will be useful for future urban park planning and conservation area selection.

The fee-for-service system is used as the main payment system for health care providers in Korea. It has been argued that it can't reflect differences in the medical practice costs across regions because the fee schedule is calculated based on the average cost. So, some researchers and providers have disputed that there is need for adopting geographic practice cost index (GPCI) used in the United States for the Medicare program for the elderly to the fee-for-service payment system. This study performed to identify whether the difference in the practice costs among regions exists or not and to examine the feasibility of applying GPCI to Korea payment system. For this purpose, we calculated modified-GPCI and examined considerations to introduce GPCI in Korea. First we identified available data to calculate GPCI. Second, we made applicable GPCI equations to Korea payment system and computed it based on four types of regions (metropolitan, urban, suburban, and rural). We also categorize the regions based on the availability of the medical resources and the capability of utilizing them. As a result, we found that there wasn't any significant difference in the GPCI by regional types in general, but the indices of rural areas (0.91-0.98) was relatively low compared to the indices of other regions (0.96-1.07). Considering the need to use GPCI floor, the pros and cons of using GPCI, and the concern of the regional imbalance of resources, the introduction of GPCI needs to be carefully considered.

Objectives: Household overcrowding (HC) can contribute to both physical and mental disorders among the members of overcrowded households. This study aimed to measure the status of HC and its main determinants across the provinces of Iran. Methods: Data from 39 864 households from the 2016 Iranian Household Income and Expenditures Survey were used in this study. The Equivalized Crowding Index (ECI) and HC index were applied to measure the overcrowding of households. Regression models were estimated to show the relationships between different variables and the ECI. Results: The overall, urban, and rural prevalence of HC was 8.2%, 6.3%, and 10.1%, respectively. The highest prevalence of HC was found in Sistan and Baluchestan Province (28.7%), while the lowest was found in Guilan Province (1.8%). The number of men in the household, rural residency, the average age of household members, yearly income, and the household wealth index were identified as the main determinants of the ECI and HC. Conclusions: The study demonstrated that the ECI and HC were higher in regions near the borders of Iran than in other regions. Therefore, health promotion and empowerment strategies are required to avoid the negative consequences of HC, and screening programs are needed to identify at-risk families.

We tried to evaluate frequencies and severities of malocclusion of various socioeconomic areas according to growth and development. To obtain objective validity, we used Handicapping Labiolingual Deviation (HLD) suggested by Draker, Treatment Priority Index (TPI) by Grainger, Handicapped Malocclusion Assessing Record (HMAR) by American Dental Association and American Association of Orthodontist. Seoul and Kwangju were selected as an urban group, Ahnyang as an middle socioeconomic group and Hwasun near the Kwangju area as an rural group. 140 (male 63, female 73) of 5th grade in 'E' elementary school students in Seoul, 202 (male 101, female 101) of 'S' elementary school students in Kwangju, 207(male 105, female 102) of 'H' elementary school students in Hwasun, and 100(male 49, female 51) of 'M' elementary school students of in Ahnyang of all the same grade were analyzed and we obtained the results as follows; 1. TPI, HLD, and HMAR showed high coincidence and reproducibility between different observer. (p<0.01) 2. In comparison of TPI, HLD, and HMAR according to clinical decision, there was statistically difference between each other. (p<0.01) 3. As the severity of malocclusion increases there was high correlation between TPI and HLD, and between HLD and HMAR (p<0.05) 4. With respect to differences between areas in TPI and HLD, there was statistically difference between Ahnyang and other areas. 5. In Seoul as an urban group there was a high incidence of periodic checkup and history of orthodontic treatment than other area. 6. Mode of feeding and posture during sleeping did not affect the severity of malocclusion. As a conclusion, TPI, HLD and HMAR are so reproducible and coincident that they can be used as a guide on evaluating the frequency and severity of malocclusion and determining the priority of orthodontic treatment to determine the need and supply of orthodontic treatment. Furthermore these indices can provide objectively valid data for establishing public health problem solution.
