This study proposes a big data-based analytical method to detect high-risk areas for solitary deaths among the elderly in Seoul. The study categorizes and analyzes the risk factors of solitary deaths into demographic, health, economic, and socio-environmental factors. Using data collected from the Seoul Open Data Plaza and Public Data Portal, variables were generated and scatter plots were created using K-means clustering, followed by visual implementation through map creation. The analysis identified Jungnang-gu, Gangbuk-gu, Nowon-gu, Eunpyeong-gu, Gangseo-gu, and Gwanak-gu as the highest-risk areas. This study addresses the limitations of previous survey-based research through big data analysis. The findings are expected to enhance the efficiency of solitary death prevention programs and serve as a basis for informed decision-making in budget allocation across districts.

Objectives : The purpose of this study was designed to estimate the effects of Oriental medical treatment on posttraumatic stress disorder patient due to a series of traffic accidents by using SCL-90-R. Methods : We studied 20 patients who were admitted to Daegu Haany University Oriental Hospital from October2006 to May 2007. Results : 4 symptoms of SCL-90-R, somatization, obsessive-compulsive, depression and anxiety were significantly different when comparing after-treatment with before-treatment. But, 5 symptoms of SCL-90-R, interpersonal sensitivity, hostility, phobic anxiety, paranoid ideation and psychoticism showed no difference between after-treatment with, before-treatment measurements. The total impact or SCL-90-R was significant comparing after-treatment with before-treatment measurements. Conclusions : We concluded that there was a significant effectof Oriental medical treatment on posttraumatic stress disorder patients caused by a seriesof traffic accident. However, the findings of this study need to be confirmed in more patients with further studies.

This study was evaluated the linearity and reproducibility according to dose, and reproducibility according to delay time by changing tube current amount (5 mAs, 10 mAs, 16 mAs, 20 mAs, 25 mAs, 32 mAs respectively, which are low energy radiations) using Glass Dosimeter (GD) and piranha semiconductor dosimeter which are used for measuring exposure dose. Measurements of radiation dose were performed using external detector of piranha 657 which is multi-function QA device (RTI Electronic, Sweden). Conditions of measurement were 80 kVp, SSD 100 cm and exposure region is $10cm{\times}10cm$. Glass dosimeter was exposed to radiation. Twenty-four glass dosimeters were divided into six groups (5 mAs, 10 mAs, 16 mAs, 20 mAs, 25 mAs, 32 mAs respectively), then measured. This study was resulted by measuring the linearity and reproducibility according to change of tube current in low energy field. In dose characteristic of GD, this study could be useful as previous study with regard to dose characteristic according to change of tube voltage in low energy field.
