Future climate changes over the Seoul metropolitan area (SMA) were predicted by the Weather Research and Forecasting (WRF) model using future land-use data from the urban growth model (SLEUTH) and forecast fields from ECHAM5/MPI-OM1 GCM (IPCC scenario A1B). Simulations from the SLEUTH model with GIS information (slope, urban, hill-shade, etc.) derived from the water management information system (WAMIS) and the intelligent transportation systems-standard nodes link (ITS-SNL) showed that considerable increase by 17.1% in the fraction of urban areas (FUA) was found within the SMA in 2020. To identify the effects of the urban growth on the temperature and wind variations in the future, WRF simulations by considering urban growth were performed for two seasons (summer and winter) in 2020s (2018~2022) and they were compared with those in the present (2003~2007). Comparisons of model results showed that significant changes in surface temperature (2-meter) were found in an area with high urban growth. On average in model domain, positive increases of $0.31^{\circ}C$ and $0.10^{\circ}C$ were predicted during summer and winter, respectively. These were higher than contributions forced by climate changes. The changes in surface temperature, however, were very small expect for some areas. This results suggested that surface temperature in metropolitan areas like the SMA can be significantly increased only by the urban growth during several decades.

Objectives: This study examined the association between ultra-processed food (UPF) consumption and chronic diseases in elderly Koreans. Methods: Data from the 2019-2021 Korea National Health and Nutrition Examination Survey were analyzed. Dietary intake and UPF consumption were assessed using the NOVA food classification based on 24-hour recall data from 3,790 participants (aged 65+ years). Participants were divided into 4 groups based on the quartile of energy intake from UPFs. Regions were classified as urban or rural. Multivariable logistic regression was employed to estimate the adjusted odds ratios (AORs) with 95% confidence intervals (CIs) after controlling for potential confounders. Results: Among the participants, 71.3% resided in urban and 28.7% in rural areas. Compared to the urban elderly, rural participants tended to be older, have lower education and income levels, be more likely to live in single-person households, and have a higher smoking rate (P < 0.05). Urban elderly consumed more UPFs daily (146.1 g) compared to rural residents (126.6 g; P < 0.05). "Sugar-sweetened beverages" were the most consumed category in both regions. "Sweetened milk and its products" and "traditional sauces" were prominent in urban areas, while rural elderly consumed more "traditional sauces" and "distilled alcoholic beverages." Rural areas also had a higher carbohydrate-to-calorie ratio than urban areas. Compared to the lowest quartile of UPF intake, the highest quartile was significantly associated with impaired fasting glucose only in rural areas (AOR, 1.48; 95% CI, 1.00-2.19; P for trend = 0.0014). No significant associations were observed for diabetes in either urban or rural areas. Conclusions: This study suggests that high intake of UPFs is associated with increased odds of impaired fasting glucose in rural elderly. Further research is needed to elucidate the specific negative health effects of UPFs in different populations, and targeted efforts should promote healthy diets in both urban and rural areas.

PURPOSES : The purpose of this study is to develop the U-turn accident model at 4-legged signalized intersections in urban areas. METHODS : In order to analyze the characteristics of the accidents which are associated with U-turn operation at 4-legged signalized intersections in urban areas and develop an U-turn accident model by regression analysis, the tests of overdispersion and zero-inflation are conducted about the dependent variables of number of accidents and EPDO (Equivalent Property Damage Only). RESULTS : As their results, the Poisson model fits best for number of accident and the ZIP (Zero Inflated Poisson) fits best for EPOD, the variables of conflict traffic, width of opposing road, traffic passing speed are adopted as independent variable for both models. The variables of number of bus berths and rate of U-turn signal time at which the U-turn is permitted are adopted as independent variable only for EPDO. CONCLUSIONS : These study results suggest that U-turn would be permitted at the intersection where the width of opposing road is wider than 11.9 meters, the passing vehicle speed is not high and U-turn operation is not hindered by the buses stopping at bus stops.

Cities of China have been expanding rapidly during the last 10 years and the living environment of urban population developed highly making little difference with the developed nations. However, in the case of rural area, situation is totally different from the urban area. There are some cases where the quality of life in rural areas is retreating compared to the past. Agrarian cultures of the past are remained in the rural area with only older generations and no younger generations. The difference between the rural and the urban and the movement to the cities are increasing in a rapid speed. This led to the recognition of potential danger that lies on the agricultural societies which can demolish the economic development's sustainability. Therefore, in this study, basic information about the current Chinese elderly's house circumstances and to build new houses suited for the older generations will be provided. This can not only enhance the quality of the elder citizen's life, but also can be a meaningful research for the ideal construction of future Chinese agriculture.

The indirect displacement estimation using acceleration and strain (IDEAS) method is extended to various types of beam structures beyond the previous validation on the prismatic or near-prismatic beams. By fusing different types of responses, the IDEAS method is able to estimate displacements containing pseudo-static components with high frequency noise to be significantly reduced. However, the concerns to the IDEAS method come from possible disagreement of the assumed sinusoidal mode shapes to the actual mode shapes, which allows the IDEAS method to be valid only for simply-supported prismatic beams and limits its applicability to real world problems. In this paper, the extension of the IDEAS method to the general types of beams is investigated by the mathematical formulation of the modal mapping matrix only for the monitored substructure, so-called monitoring span. The formulation particularly considers continuous and wide beams to extend the IDEAS method to general beam structures that reflect many real bridges. Numerical simulations using four types of beams with various irregularities are presented to show the effectiveness and accuracy of the IDEAS method in estimating displacements.

High resolution panchromatic satellite images collected by sensors such as IRS-1C/D and KOMPSAT-1 have a spatial resolution of approximately 6 ${\times}$ 6 ㎡, making them very attractive for urban applications. However, the spectral information present in these images is very limited. In order to overcome this limitation, an object-oriented classification approach is used to identify basic land cover types in urban areas. Before an image can be classified it is segmented at different aggregation levels using a multiresolution segmentation approach. In the course of this segmentation various statistical as well as topological information is collected for each segment. Based on this information it is possible to classify image objects and to arrive at much better results than by looking only at single pixels. Using an image recorded by KOMPSAT-1 over the City of Vienna a land cover classification was carried out for two areas. One was used to set up the rules for the different land cover types. The second subset was classified based on these rules, only adjusting some of the functions governing the classification process.

본 연구는 지방도시의 하나인 대구를 대상으로 1960년대부터 현재까지 시대별로 도시공원의 계획 개원과정을 분석하고, 이를 시대적 상황과 연관 지어 고찰함으로써 도시공원의 변천에 나타난 사회적 의미를 해석하였다. 1960년대에 도시계획법과 공원법이 제정되면서 법제도 내에서 도시공원이 조성되기 시작하였다. 하지만 이때에는 도시공원이 단지 도시계획시설의 하나로만 인식되어 조성보다는 지정에만 급급하였다. 1970년대는 급격한 도시화와 폭발적인 인구 증가에 대처하기 위해 도시공원의 양적 확보에 주력하였으나, 예산부족으로 계획기간 내에 공원 조성이 완료되지 못하였다. 1980년대는 연이는 대규모 국제대회 개최로 인하여 도시미화를 위한 각종 녹화계획이 수립되면서 도시공원의 미적 기능이 재인식되었으며, 도시민의 이용욕구를 만족시키기 위해 정적공간뿐만 아니라 동적시설을 갖춘 복합적인 성격의 도시공원이 조성되기 시작하였다. 1990년대는 환경문제에 대한 관심 증대와 함께 공원에 대한 시민의 적극적인 관심표명 및 참여가 이루어지기 시작하였으며, 도시공원의 환경적 기능과 효과의 부각에 따라 도시공원의 양적 확대뿐 아니라, 질적 개선도 함께 이루어졌다. 우리나라에 있어 근대적 의미의 도시공원 도입은 구한말부터이고, 본격적으로 도시공원이 조성되기 시작한 것은 1960년대부터이다. 하지만, 본 연구를 통해서 도시공원의 변화과정에 나타난 사회적 의미를 종합해 볼 때 대구에서 시민을 위한 '공용(共用)의 휴식처'라는 본연의 의미와 목적에 부합되는 도시공원의 개념이 완성된 것은 1990년대에 와서라고 할 수 있다.

본고는 중국의 20세기 도시건설 기록물 관리사업에 대하여 고찰하였다. 우선 12개 항목의 기본건설 당안과 11개 부문의 도시건설 당안을 알아보았고, 도시건설 당안관의 당안 수집방법, 임무, 서비스범위 등에 대하여 살펴보았다. 도시건설 기록물 관리사업은 중대형의 도시건설계획과 마오저뚱의 도시건설 기록물 처리에 대한 지시에 의하여 국가적 차원에서 정책적으로 적극 추진되어 왔다. 따라서 2003년 현재 전국적으로 각급 각종의 당안관 3,816개관이 건립되었으며, 1960년대에 42곳에서 추진되기 시작하였던 도시건설 당안관은 전국 662개의 도시에 모두 건립되었다. 한편 현재 도시건설 당안관의 인적자원의 경우 전체 인적자원 대비 전문대학이상 졸업자를 70~80%, 중급 기술직을 60~70%로 배치하여 전체 인적자원 대비 전문인적 자원이 최소 60% 이상 배치되도록 하고 있다. 이러한 수치와 비율은 도시건설 기록물관리 사업을 양적 및 질적 측면에서 모두 적극적으로 추진한 결과이다. 북경시의 도시건설 기록물관리 상황을 살펴 본 결과 전문적인 도시건설 당안관 외에 해당 지역의 당안관에도 도시건설 당안들이 수집 관리되고 있음을 알 수 있었다. 또한 우리나라의 도시건설관련 기록물 관리에 대하여 나아갈 방향을 제안하였다.
