The purpose of this study was to develop a semi-quantitative food frequency questionnaire (SQ-FFQ) for subjects aged 50yr and over and to evaluate the validity of this SQ-FFQ. Dietary intake was assessed using SQ-FFQ that included 98 commonly consumed flood items selected from the results of the Korean Health and Nutritional Survey, 1998. Subjects (n = 2,660) aged 50yr and over were recruited from 7 metropolitan cities and 8 small cities. Each subject was interviewed using this SQ-FFQ developed in our laboratory and 24hr-recall method. Excluding incomplete data, Data from 1,149 subjects were used in this validity study. The nutrient intakes assessed by this SQ-FFQ were validated by comparing with the results from 1 day 24-hour recalls. Pearson's correlation coefficients between two methods were 0.71, 0.64, 0.53, and 0.43 for energy, carbohydrate, protein, and fat, respectively for all subjects. Spearman's correlation coefficients were higher than those of Pearson's correlation coefficients. Kappa values for energy, carbohydrate, protein, and fat were 0.79, 0.72, 0.70, and 0.64, respectively. The percentage for misclassification of the lowest quartile into the highest quartile or vice versa was 1.25-1.39% for all nutrients. Therefore, this SQ-FFQ seems to be useful in assessing the nutritional status of the middle-aged and elderly subjects in Korea.

The present study aims to evaluate the characteristics of atmospheric polycyclic aromatic hydrocarbons (PAHs) pollution in roadside and residential areas of two Korean metropolitan cities (Seoul and Incheon) and a background area (Seokmolee). This purpose was established by analyzing temporal and spacial concentration distribution of total and 7 individual PAHs, which were extracted from ambient particulate matters, and by utilizing a multivariate statistical method (principal component analysis, PCA) for the qualitative determination of potential PAH sources. Target PAHs included benzo(a)anthracene (BaA), benzo(a)pyrene (BaP), benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF), chrysene (Chr), dibenzo(a,h)anthracene (DahA), and indeno(1,2,3-cd)pyrene (IcdP). For all surveyed sites, the concentrations of total PAHs were higher in winter season than in other seasons. However, the concentrations of individual PAHs varied with surveyed sites. In both residential and roadside sites of Seoul and Incheon, BbF revealed the highest atmospheric levels. For all 7 target PAHs, the ambient concentrations were higher in Seoul and Incheon than in a background area (Seokmolee). In both residential and roadside areas, the concentrations of 4 target PAHs (BaA, BbF, BkF, DahA) were higher in Incheon than in Seoul. However, both the residential and roadside Chr concentrations were comparable in Seoul and Incheon. In addition, the residential IcdP concentrations were higher in Incheon than in Seoul, whereas the roadside concentrations were higher in Seoul. The roadside and residential BaP concentrations exhibited the reverse result to the IcdP concentrations. An PCA analysis suggested that atmospheric PAHs in both residential and roadside areas would be due to combined effects of several potential sources such as gasoline- and diesel-fueled vehicles, coal/oil combustion, and waste incineration.

Purpose: The study has been undertaken on several factors that may influence on the orthodontic treatment satisfaction with the subject of male and female university students who have experience in receiving the orthodontic treatment by visiting orthodontic clinic. Methods: This study has implemented questionnaire survey for 350 male and female university students who have experience in receiving the orthodontic treatment by visiting orthodontic clinic due to the mall occlusion, From the 350 questionnaires collected, a total of 291 copies (83.1%) excluding the questionnaires that have inconclusive response or erroneous response is used as the research analysis data Results: The orthodontic treatment satisfaction is significantly higher for students in large cities and mid- to small sized cities than students in rural area, and it was higher for students with mid-economic class that students of upper class and lower class. It is shown for a student that began the orthodontic treatment from the elementary school, a student that had 5 times or more of brushing teeth for each day had significantly higher level of satisfaction that students that are not. In addition, a student that knows well of the oral hygiene management method, a student that had the fluoride application treatment during the orthodontic treatment period and a student that used the toothbrush for orthodontic service had significantly higher level of satisfaction that students that are not. Conclusion: Factors influencing on the orthodontic treatment satisfaction are very diverse and it is considered that it requires effort to improve the quality of medical service and sufficient understanding on several factors to improve the orthodontic treatment satisfaction for patients as well as the encouragement for orthodontic treatment patients of the relevant people in orthodontic clinics that provide the orthodontic clinic service.

Purpose: The purpose of this study was to explain a structural model of posttraumatic growth among psychiatric nurses based on existing models and a literature review and verify its effectiveness. Methods: Data were collected from psychiatric nurses in one special city, four metropolitan cities, and three regional cities from February to March 2016. Exogenous variables included hardiness and distress perception, while endogenous variables included self-disclosure, social support, deliberate rumination, and posttraumatic growth. Data from 489 psychiatric nurses were analyzed using IBM SPSS Statistics 19.0 and AMOS 20.0. Results: The modified model was a good fit for the data. Tests on significance of the pathways of the modified model showed that nine of the 14 paths were supported, and the explanatory power of posttraumatic growth by included variables in the model was 69.2%. For posttraumatic growth among psychiatric nurses, deliberate rumination had a direct effect as the variable that had the largest influence. Indirect effects were found in the order of hardiness, social support, and distress perception. Self-disclosure showed both direct and indirect effects. Conclusion: A strategy to improve deliberate rumination is necessary when seeking to improve posttraumatic growth among psychiatric nurses. Enhancing psychiatric nurses' hardiness before trauma would enable them to actively express negative emotions after trauma, allowing them to receive more social support. This would improve deliberate rumination and consequently help promote psychological growth among psychiatric nurses who have experienced trauma.

With industrial restructuring and growing competition among places throughout the world, many countries including Korea are getting highly dependent on place marketing as their development strategy. Previous discussions on place marketing strategy maintain that the strategy should be performed on the basis of the unique placeness of each place. Not all places, however, have placeness that can be used for the place marketing strategy. Also, there are some cases of success in place marketing by introducing elements irrelevant to the places. In this context, this study aims to analyze previous debates on place and place marketing, and to investigate the possibility of creating placeness. In addition, it selected as case places the city of Ashland and the city of Jacksonville in the state of Oregon, USA and Tongyeong-si in Korea and examined how the art festivals, one of major means of place marketing, can be used in creating placeness.

This study examines and analyzes residential environment and consciousness of downtown residents in Naju city and its results are as follows. Naju's population or urban population were decreased by half for 25 years, but area of residential regions was increased twice. It indicates that major parts of increased residence area are occupied by housing site development area. Uses of downtown buildings are for residential building mostly, but commercial building is less than 1/3 and story of buildings is mostly the first floor. So downtown area in Naju has residential function mostly and family composition is over sixties in more than half of population and regional aging is remarkable because household over majority of the population has no family under twenties. Downtown areas showed detached house and their own house in 2/3 of population and residents over majority of population have lived in current house over 20 years and had strong settlement. But housing site area is less than 40 pyeong at 3/2 of population and 2/3 of population have not parking lot. Most of population have dissatisfaction with their residential environment and for solving their dissatisfaction, improvement of poor residential environment, road extension and construction of parking lot are needed most. Most of residents consider that improvement of residential environment or economic level is normal or developed a little compared to five years ago, but when such a dissatisfaction is solved, they continue to live in their area.

This research was conducted to understand and analyze the physical awareness symptoms of college students and get fundamental research data essential to provide efficient student guidance and public health service at schools. The survey was carried out for 1 month from May 7th, 2001 to June 7th, 2001. The interviewees were 950 enrolled students at junior colleges in Daegu. 26.5% of them were men and 73.5% women. Among the surveyed, public health majors were 76.9%. Daytime students were 64.1 %, and the majority of the students, 42.8%, were atheistic. 56.0% of the students grew up in big cities, 22.2% in medium and small-sized cities, and 21.8% in farming and fishing communities. 66.1 % used public transportation. The majority of the students, 48.7%, answered that the satisfaction level for their majors was average. The result shows that the ocular fatigue was indicated as a greatest complaint, and the female students showed the higher complaint rate than the males. In the study of the complaining rate of physical symptoms by major, the public health majors showed the highest complaining rate in gasping when going up/down stairs, shoulder pain, a burning feeling on empty stomach, and leg/knee pain. On the other hand, the highest complaint factors for the technical majors were ocular fatigue and the feelings of heavy head. In the study of the complaining rate of physical symptoms by transportation, gasping during going up/down stairs and shoulder pain were most common, which were 52.2% and 36.0% respectively. In the study of the insecurity response distribution by transportation, college students who drive a car showed 3.8% and students using public transportation 3.7%. In the study of the insecurity response by subject satisfaction, students who answered dissatisfactory were 8.3%, average 3.9%, satisfied 3.0%. Therefore, it was concluded that students who were dissatisfied with their subjects showed the higher rate of insecurity response. it can be recommended that a school health education program regarding ocular fatigue and shoulder pain should be developed.

The purpose of this study is to have detailed data of the distribution, locations, and the amount of people in the waiting line of the nursing home. Also, we studied the accessibility to the facilities by using Web GIS to analyze the transit time it takes from the nursing home to health center and hospitals. We can provide the basic data that could contribute when future plans for the nursing homes' locations, health and medical policy are made. The results are as follows. 1. The nursing homes are stiffly concentrated in regions of Seoul and Gyeongi-do where large number of the elderly covered by long-term care insurance and the waiting line was very long for the elderlies to enter the nursing homes. In these cities of Ulsan and Jeju where number of the elderly covered by long-term care insurance is relatively small, there were less facilities. 2. The nursing homes located in urban areas had higher occupancy rate and higher number of people in the waiting line. 3. The average time taken by driving from the nursing homes and health center was 10 minutes and there was not a noticeable difference between the cities. Driving from the nursing homes to hospitals in rural areas took 22 minutes which is 2.5 times of the time taken for urban areas. Daegu-si and Incheon-si had relatively short distance from the nursing homes and the hospitals while Jeju-do had the furthest. For rural areas, it is needed for health center to be equipped with a wider medical coverage, have closely connected with hospitals to minimize the differences they have from ones in rural areas. It is also needed to have ambulances equipped for tele-medical examination and treatment system.

Nowadays, reduction of energy use in buildings is a big issue, especially in public buildings like schools. The building structure is very simple in that, the room size, schedule and user number is similar across different schools. There are many policies which are suitable for this kind of buildings. Investigation of energy consumption pattern in primary school, middle school and high school in different cities of Korea has been done in this paper using statistical data from national organization and the data from IBM and Gyeonggi Provincial Office of Education, aimed at providing the basic data for the development of energy efficiency improvement policies of educational facilities. The study was divided according to climate, energy source type and public or private school, as different cities have different climates and accordingly different amount of energy sources are used. It was observed that, the average energy consumption in primary school is $36.9kWh/m^2$, in middle school is $20.5kWh/m^2$ and in high school $27.4kWh/m^2$. As further analysis, monthly energy consumption pattern has been analyzed for one city.

This study assessed the relationships between levels of $PM_{10}$ and hospitalization rates for asthma among children from 2003 to 2005 at four major cities in Korea. In addition, we estimated the reduced number of asthma hospitalization associated with an ambient $PM_{10}$ improvement to the acceptable levels as recommended by the World Health Organization (WHO). The Generalized Additive Model (GAM) was used to estimate the relative risks (RR) of asthma hospitalization associated with changes in $PM_{10}$ The RRs of children's asthma hospitalization for every $10{\mu}g/m^3$ increment in $PM_{10}$ were 1.009(95% CI = 1.004-1.014) in Seoul, 1.013(95% CI = 1.006-1.021) in Incheon, 1.009(95% CI = 1.002-1.016) in Busan, and 1.021(95% CI = 1.005-1.037) in Ulsan. We assessed $PM_{10}$ related health benefits from implementing the WHO's guidelines (24-hour average $50{\mu}g/m^3$) using the U.S. Environmental Protection Agency's Environmental Benefits Mapping and Analysis Program. The estimated benefits were 439(95% CI = 216-666) reduced asthma hospitalization in Seoul, 720(95% CI = 304-1,151) in Incheon, 260(95% CI = 66-459) in Busan, and 126(95% CI = 30-228) in Ulsan. It was concluded that improving $PM_{10}$ condition to the WHO guideline would make a significant contribution to the reduction in asthma hospitalization among children. Therefore, public health measures are still needed to improve air quality in Korea.
