The purpose of this study is to present a plan to distinguish 229 local governments nationwide by taking into account various characteristics such as population, employment, housing, and industry of the region for customized urban policies in the era of metropolitan areas. The National Statistical Portal (KOSIS) collected and standardized data related to population, housing, industry, and finance by region from 2000 to 2015 for the classification of regional types necessary for customized urban policies, and this was used to classify them into regional types that considered population, employment, housing and industry. The summary of the analysis results is as follows. First, as a result of the regional type classification, 10 key employment sites (4.4%), 5 employment centers (2.2%), 38 residential centers (16.6%), 20 growth areas (8.7%), 26 industrial cities (11.4%), 35 low-fertile farming and fishing villages (15.3%) and 95 stagnant areas (41.5%). Second, the Seoul metropolitan area is the most diverse type of metropolitan area in the country, with most of its core employment sites inside Seoul, residential centers inside and outside Seoul, and growth areas in the southeastern part of the country (Busan, Ulsan, and Gyeongsangnam-do) are mixed with industrial and growth areas centered around Busan, Ulsan and surrounding areas, while the rest of the local governments are found to be low-fertile farming villages or stagnant areas. Daegu (Daegu, Gyeongbuk) is an industrial city in Daegu, and the rest of the local governments are either low-density farming and fishing villages or stagnant areas. The Honam region (Gwangju and Jeolla) was found to be a low-mill farming and fishing village or stagnant area except for Gwangju, while the Chungcheong region (Daejeon, Sejong, and Chungcheong) was seen as a growth area with areas adjacent to Daejeon, Sejong, and the Seoul metropolitan area, and some industrial cities were included. Finally, the Gangwon area was mostly classified as low-density farming and fishing villages and stagnant areas.

Purpose: This study was performed to evaluate the reproducibility of panoramic radiographs of dentulous and edentulous patients. Materials and Methods: The reproducibility of panoramic radiographs was evaluated using the panoramic radiographs acquired from 30 anterior dentulous patients by using a common biting positioning device (dentulous group) and 30 anterior edentulous patients by using chin-support devices to take a panoramic radiograph (edentulous group), respectively; these patients had undergone 3 or more panoramic radiographs. The widths and angles between the designated landmarks were measured on the panoramic radiographs, and the reproducibility was evaluated using the intraclass correlation coefficient (ICC) and the coefficient of variation. Results: In the dentulous and edentulous groups, the ICCs of the mandibular ramus and mandibular angle areas were higher than the condylar head and zygomatic areas. The mandibular ramus and angle areas showed statistically lower mean coefficients of variation than the condylar head and zygomatic areas in the dentulous group. The mandibular angle area showed a significantly lower mean coefficient of variation than the zygomatic area in the edentulous group. By comparing the two groups, each ICC of the edentulous group was lower than that of the dentulous group, and the mean coefficients of variation of the mandibular ramus area, zygomatic area, left condylar inclination, and ramus ratio between the right and the left in the edentulous group were significantly higher than those in the dentulous group. Conclusion: Biting positioning for dentulous patients provided better positioning reproducibility than chin-support positioning when performing panoramic radiography for edentulous patients.

This study aims to provide information about the acute poisoning patients transferred by 119 ambulance service for nurses and emergency medical technicians. The data is based on 119 ambulance services patients charts of Seocho area in Seoul. The results were as follows: 1. Total number of emergency patients all over the country has been nearly fourtimes in 1995 compared to 1991. Total number of emergency patients were 322.051 in 1994. 2. About $35\%$ of total E.R. patients were transferred by 119 ambulance services in Seoul in the last 5years. Acute drug intoxication patients occupied $2-3\%$ of E.R. patients in Seoul. 3. About $4\%$ of E.R. patients in Seoul were transferred by 119 E.R. services of Seocho area in Seoul in 1995. Among them $2.4\%$ patients were drug intoxication patients. 4. Data were collected from available patients of 119 ambulance services from Jan. 1993 to Dec. 1995 in Seocho area. Total poisoning patients were 184. - The female/male ratio was 69.7:30.4 and most of patients$(69.7\%)$ were in the age of 20th and 30th. - The busy time of calling 119 ambulance service was from 6P.M. to midnight$(37.5\%)$ - It took within 10 minutes for patients$(62.8\%)$ from notification to arrival in hospital. - Regarding poisoning substances. hypnotics $(22.8\%)$, tranquilizer$(14.7\%)$, agricultural agents$(6.0\%)$ rodenticide$(27\%)$ and others $(10.3\%)$ were in order and unknown were $43.5\%$. - Most of the patients or protector $(72.8\%)$ chose hospitals. Among them $(87.3\%)$ were general hospital. - The most predominant symptoms were coma$(22.3\%)$. dizziness$(6.5\%)$ and then allergy. vomiting. gastrointestinal cramps etc. - Airway management and oxygen administration together was the main medical control of prehospital emergency medical services$(33.7\%)$. It is proposed that first, a systematic survey of drug intoxication patients must be conducted to give an appropriate prehospital emergency care for the emergency medical technician and second, a wide and regular public education to improve understanding of first aids should be undertaken.

This study analyzed the health risk behavior of Korean college students by comparing them based on the college location (Seoul vs. non-Seoul). Converging analyses of health risk behaviors (drinking behavior, sex, suicidality) and health risk factors (mental health, stress) were attempted. The results showed the 23% of students were at risk of serious drinking problem, and the 52.6% of students consumed alcohol once in every other week or more often. In case of the sexual behavior, 40.6% had sexual experience. Importantly, the 25.4% and the 20.3% of college students in Seoul and non-Seoul area, respectively, had two or more sexual partners. Also, students in non-Seoul area had a tendency of the higher level of suicidality, and the lower level of mental health. Overall, the self-respect score was the only statistically significant factor showing the Seoul/non-Seoul difference. These results may be able to intervene the health risk behaviors of college students.

The Seoul's 2030 Youth-Housing is a policy to promote the development of private sector-built rental housing in a Station Influence Area (SIA). It is a representative policy to resolve a housing problem for the youth in Seoul. The Seoul Metropolitan Government has made continuous policy improvements to respond to earlier criticisms on the policy. In December 2018, the Seoul Metropolitan Government enlarged the possible spatial boundaries of the SIA that the private sector developer can carry out the housing development projects. This study attempts to assess the potential sites available in Seoul by considering the youth's demand. This study used the suitability modelling technique to evaluate the potential sites. In detail, we established three sub-models by reflecting rent, accessibility to living areas of the youth, and accessibility to living SOC for the youth's demand. According to the results, the Hanyang City Wall area, which was newly included by the recent policy revision, showed moderate scores to fit the housing projects, while some Gangbuk areas, which have high accessibility and relatively lower rents, showed the best scores appropriate for the projects. The age group of 20s preferred university districts, while the age group of 30s preferred to locate near Seoul's main office areas. We suggest that the Seoul metropolitan government develops better ways to guage and reflect the demand for differing youth groups and the demand by age groups.

The purpose of this study was to compare and apply quantitative indices for analyzing the total green space in an urban area, targeting Guro-Gu, Seoul. The indices were classified in terms of plane, solid and urban planning. The park area per person as an index of the park green's total volume was $2.34m^2$. This clearly shows the deficiency of park area. However, it did not reflect actual green space, since undesignated forests, rivers and green spaces in the city were excluded. Green coverage area per person in terms of plane was $18.85m^2$ and was useful as an index of actual urban planting, focusing on expansion of the green space. However, the conception of total volume of park green had limitation to be recognized as a unit of area. The number of trees and green area volume per person in terms of solid was 4.1 trees and $35.8m^2$, respectively. This enabled reflection on qualitative improvement plans such as increasing the volume of trees for the high density of developed areas.

The purpose of this research is to recognize college students' thinking way for hair fashion. The tendency of hair style, hair dyeing and hair administration was examined with college students in Seoul, some cities and towns. Research analyzed and compared the result according to the distinction of sex, age and area. The questionnaire was asked to 257 boy students and 328 girl students. The result in this research is as following. 1. It was shown that our country college students were satisfied with their hair style on the whole. Especially, college students in Seoul appeared more satisfied tendency than other city or town. Seoul's college students preferred hair style of short haircut. Wide area city or small town's college students preferred long hair style. The degree of satisfaction about beauty salon service of Seoul city's college students is higher than that of wide area city or small town's college students. The reasons that they want to go to the beauty salon they used to are distance for boy students and excellent technology for girl students. Boy students change hair style regularly, but girl students change it when need to change their mood. 2. In our country, most college students had experienced that they had their hair dyed. More senior students had their hair dyed than junior students. Hair color that most like was nature brown. Seoul college students liked gold color. Seoul college students are more satisfied than wide area city or small town's college students after hair dyeing. Girl students thought that hair dyeing made their hair style excellent. 4. Girl students responded that their hair was much damaged. College students in Seoul had healthy hair. Girl students selected 「beauty art surgical operation」 for cause of hair damage, and boy student had the various causes of hair damage. College students in Seoul had much hair damage than students in any other area. Most were using shampoo, and girl students used much shampoo than boy students. Girl students selected shampoo according to their hair state, Seoul's college students had their hair washed with shampoo more frequently than other students. Girl students were getting more hair administration information with various form than boy students. Girl students used Hair Clinic for hair administration, but boy students never did it.

The analysis and comparison on the usage of public cremation facilities located in Seoul through online reservation service of ehaneul funeral information system by area from Jan. 1, 2011 to Dec. 31, 2017 showed that among 314,877 in the number of bodies using the facilities, 225,828 (or 71.7%) belonged to Seoul citizens and 89,049 (or 28.3%) belonged to people living in other area than Seoul, such as Goyang city, Gyeonggi-do and other local governments. Therefore, there appeared that the Seoul citizens could not get the timely cremation service but instead extended the funeral service to 4 to 5 days or had to go to the remote area for cremation. This trend gets severe every year. To solve these problems, it is recommended that Seoul city government makes effort of constructing or expanding the public cremation facilities in cooperation with other local government of the area whose residents show high rate of using Seoul public cremation facilities and that Seoul city government expands or builds its own public cremation facilities in mid- and long-term. In addition, the local government of other area around Seoul needs to expand their use rate of their own (4) public cremation facilities or raise the creation fee for the residents from other areas, thus trying to dispersing and controlling the demand for the cremation.

Background: In this study, we investigate the rapid increase in environmental odors and notable rise in civil complaints near Dorim Stream in the Gwanak-gu area of Seoul. Objectives: This study aims to identify the causal compounds responsible for environmental odors in the Dorim Stream and investigate the structural characteristics of the stream that influence odor generation. Methods: The research methodology involved setting up 41 sampling points, selecting panels for direct sensory evaluation to assess odor intensity, measuring dissolved oxygen and hydrogen sulfide concentrations, and using all-in-one low-temperature desorption gas chromatography (ATD-GC) and thermal desorption-gas chromatography-mass spectrometry (TD-GC/MS) analysis to identify odor-causing compounds. Results: The evaluation of Dorim Stream revealed that in areas with complete meandering, there were lower dissolved oxygen levels (4.5±2.67 mg/L) and higher odor intensity (4.0±0.92), while in partially meandering sections, higher dissolved oxygen levels (7.8±1.15 mg/L) and lower odor intensity (2.8±1.06) were observed. Hydrogen sulfide levels measured with sensors increased with higher temperatures, especially in the afternoon hours (12:00~14:00). Acetaldehyde was the dominant odor compound detected in both the Bonglim Bridge (0.4 ppm) area and Guro Bridge area (0.867 ppm), with concentrations more than twice as high near Guro Bridge. Odor-causing compounds identified by TD-GC/MS indicated a pungent, sulfurous odor in the Guro Bridge area and a musty odor in the Bonglim Bridge area. Conclusions: This study categorizes and analyzes the sources of odor in Dorim Stream in Seoul based on meandering patterns and the distribution of sewage facilities, highlighting the potential odor issues associated with combined sewage systems and sewer junctions and suggesting policy improvements.
