The urban railway system is a convenient public transportation system, as it carries many people without increasing traffic congestion. However, air quality in urban railway environments is worse than ambient air quality due to the internal location of the source of air pollutants and the isolated space. In this paper, characteristics of particulate matter (PM) pollution in urban railway environments are described from the perspective of diurnal variation, chemical composition and source apportionment of PM. PM concentrations in concourse, platform, passenger cabin, and tunnel are summarized through an analysis of 34 journal articles published in Korea and overseas. This information will be helpful in developing effective policies to reduce PM pollution in urban railway environments.

- Abstract - Objectives: The purpose of this paper is to determine an efficient operation plan for a smoking cessation clinic in public health centers. To do so, the primary success factors in smoking cessation have been analyzed after classifying the smoking cessation programs of public health centers into urban and rural areas. Methods: A study was conducted with 262,837 smokers age 19 or older who were provided with smoking cessation services for more than 6 months through smoking cessation clinics at public health centers(250 clinics nationwide) from July 16, 2006 to July 15, 2007. Results: Urban areas indicated that gender, age, social security, the frequency of counseling, re-enrollment in the program, the number of cigarettes per day and alcohol problems were all factors that influenced the success of smoking cessation. On the other hand, in the rural areas the total number of counseling, re-enrollment in the program, the number of cigarettes per day and alcohol problems were the influential factors. Furthermore, the urban area confirmed that the frequency of counseling, re-enrollment in the program, the number of cigarettes per day and alcohol problems affected traveling while the rural area was affected by social security, the frequency of counseling and re-enrollment. Conclusions: It has been confirmed that the success rate and factors of smoking cessation clinics can vary depending on the region and enrollment method.

To find causal factors and improvement plans of organizational commitment of public servants in urban health centers, a hypothetical causal model, which included 2 endogenous variables(organizational commitment & organizational satisfaction) and 15 exogenous variables, was constructed. Exogenous variables consisted of individual factors (sex, age, education, job-grade, and annual salary), psychological variables(pride for organization, extrinsic motivation, intrinsic motivation and support of supervisor) ad structural variables(formalization, centralization, communication, job-conflict, job-decision, and workload). In the hypothetical causal model, organizational commitment was supposed to be effect variable, and organizational satisfaction was presumed to be intervening variable to mediate between organizational commitment and exogenous variables. For data collection, cross-sectional self-administered questionnaire survey was conducted to 1,295 public servants from 32 urban health centers nationwide. The survey responses were from 934, 72.1% of subjects. But 756 responses(58.4%) were analyzed because of excluding ones with missing values. The hypothetical causal model was fitted by covariance structural analysis with maximum likelihood method. Main results were as follows: (1) The fitted causal model accounted for 33 and 55 percent of total variance of organizational commitment and organizational satisfaction of public servants, respectively. (2) In order of effect size, pride for organization, supervisor support, communication, extrinsic motivation and centralization had an indirect effect effect on organizational commitment through organizational satisfaction. However, the effect of centralization was negative. (3) Pride for organiztion, intrinsic motivation, organizational satisfaction, job-conflict, supervisor support, communication, age, centralization, annual salar and extrinsic motivation had indirect or direct effects on organizational commitment in order of effect size. Among them, effects of job-conflict and centraldization were negative. In conclusion, these results suggested that organizational commitment of public servants in urban health centers could be enhanced by pride for organization, intrinsic and extrinsic motivations, prevention of job-conflict and excess centralization, supervisor support and active communication. Especially, pride for organization and intrinsic motivation were expected to play the most important role.

Purpose: This study was conducted to differentiate the factors associated with the BMI group of adolescents between rural and urban areas, and provide baseline data in the development of health education programs considering their personal and environmental characteristics. Methods: Secondary data analysis was performed using the data from an on-line survey of the 9th adolescence behavioral health in 2013. The instruments included general, behavioral, and psychosocial characteristics. This study was a cross-sectional survey conducted with 26,513 adolescents. The data were analyzed using a t-test, two-way ANOVA, and multinomial logistic regression analysis. Results: Significant differences in the prevalence of obesity between urban and rural areas were nated and rural areas exhibited a higher prevalence of obese adolescents (p<0.05). The factors associated with the BMI group were the mothers' education level (low) and lower age of adolescents (middle school) in rural areas, wherase those for urban areas were gender (boys) and the fathers' education level (low) (p<0.05). Conclusion: Because there was a significant difference in the prevalence of obesity between rural and urban areas, it is necessary to develop a tailored education program considering the regional and environmental characteristics that the adolescents belonged to in order to prevent and control adolescent obesity.

Urban transit or subway stations generally service for a long period of several decades. And, the urban transit or subway is public transportation which lots of people takes every day. During the service time, they are inevitably damaged from environmental corrosion, material aging, fatigue, and the coupling effects with long-term loads and extreme loads. The included damage accumulates and performance degenerates due to the above factors. They would inevitably reduce the resisting capacity of station against the disaster; even they result in collapse with the structural failure under extreme loads. And, if disaster such as earthquake, fire, etc. happens, it causes huge property damage and threatens the human lives. Because of these above reasons, the intelligent health surveillance system should be researched and developed for ensuring the safety of station. In this paper, the research plans of the intelligent health surveillance system of urban transit station are presented. And also, the development or establishment directions of this system are suggested.

Purpose: To understand the dietary habits and factors influencing the dietary habits in adults of an urban community. Method: The data were collected via questionnaires that investigated dietary habits, health behaviors, health-related factors, and general characteristics. A total of 302 subjects were selected from those who had visited an urban public center over a 2-week period. The data of 294 subjects were analyzed using descriptive analysis, t-test, ANOVA, and multiple regression, after 8 questionnaire were excluded due to incomplete data. Results: The degree of dietary habits was in the middle range. The most positive dietary habit was 'intake fibers from vegetables, fruits, and cereals', followed by 'not enjoy salty food and salt' and 'eating breakfast everyday'. The significant predictors influencing dietary habits were age, present smoking behavior, perceived health status, and drinking frequency, and these variables accounted for 27.3% of the variance in the dietary habits score. Conclusion: Health care providers should focus on health promotion planning regarding dietary habits and other health-related behaviors in combination and use integrated strategies regarding the factors that influence dietary habits and other health-related behaviors.

The objective of the study are two-fold: one is to explore the relationship between environment, organizational structure, and organizational effectiveness of public health centers in Korea, and the other is to examine the validity of contingency theory for improving the organizational structure of public health care agencies, with special emphasis on public health nursing administration. Accordingly, the conceptual model of the study consisted of three different concepts: environment, organizational structure, and organizational effectiveness, which were built up from the contingency theory. Data were collected during the period from 1st of May through 30th of June, 1990. From the total of 249 health centers in the country, one hundred and five centers were sampled non proportionally, according to the geopolitical distribution. Out of 105, 73 health centers responded to mailed questionnaire. The health centers were the unit of the study, and a various statistical analysis techniques were used: Reliability analysis(Cronbach's Alpha) for 4 measurement tools; Shapiro-Wilk statistic for normality test of measured scores of 6 variables: ANOVA, Pearson Correlaion analysis, regressional analysis, and canonical correlation analysis for the test of the relationships and differences between the variables. The results were. as follows : 1. No significant differences between forma lization, decision-making authority and environmental complexity were found(F=1.383, P=.24 ; F=.801, P=.37). 2. Negative relationships between formalization and decision-making authority for both urban and rural health centers were found(r=-.470, P=.002 ; r=-.348, P=.46). 3. No significant relationship between formalization and job satisfaction for both urban and rural health centers were found (r=-.242, P=.132, r=-.060, P=.739). 4. Significant positive relationship between decision - making authority and job satisfaction were found in urban health centers (r=.504, P=.0009), but no such relationship was observed in rural health centers. Regression coefficient between them was statistically significant($\beta=1.535$, P=.0002), and accuracy of regression line was accepted (W=.975, P= .420). 5. No significant relationships among formalization and family planning services, maternal health services, and tuberculosis control services for both urban and rural health centers were found. 6. Among decision-making authority and family planning services, maternal health services, and tuberculosis control services, significant positive relationship was found between de cision-making authority and family planning services(r=.286, P=.73). 7. A significant difference was found in maternal health services by the type of health centers (F=5.13, P=.026) but no difference was found in tuberculosis control services by the type of health centers, formalization, and decision-making authority. 8. A significant positive relationships were found between family planning services and maternal health services and tuberculosis control services, and between maternal health services and tuberculosis control services (r=-.499, P=.001 ; r=.457, P=.004 ; r=.495, P=.002) in case of urban health centers. In case of rural health centers, relationships between family planning services and tuberculosis control services, and between maternal health services and tuberculosis control services were statistically significant (r=.534, P=.002 ; r=.389, P=.027). No significant relationship was found between family planning and maternal health services. 9. A significant positive canonical correlation was found between the group of independent variables consisted of formalization and de cision-making authority and the group of dependent variables consisted of family planning services, maternal health services and tuberculosis control services(Rc=.455, P=.02). In case of urban health centers, no significant canonical correlation was found between them, but significant canoncial correlation was found in rural health centers(Rc=.578, P=.069), 10. Relationships between job satisfaction and health care productivity was not found significant. Through these results, the assumed relationship between environment and organizational structure was not supported in health centers. Therefore, the relationship between the organizational effectiveness and the congruence between environment and organizational structure that contingency theory proposes to exist was not able to be tested. However decision-making authority was found as an important variable of organizational structure affecting family planning services and job satisfaction in urban health centers. Thus it was suggested that decentralized decision making among health professionals would be a valuable strategy for improvement of organizational effectiveness in public health centers. It is also recommended that further studies to test contingency theory would use variability and uncertainty to define environment of public health centers instead of complexity.

This paper used two threshold approaches to measure the equity in urban households' out-of-pocket payments for health care from 1997 to 2002, which developed by Wagstaff and van Doorslaer. One approach used catastrophic health expenditure, which means that payments exceed a 'pre-specified proportion' of total consumption expenditures or ability to pay and the other used impoverishment that they did not drive households into poverty. Indicies for 'catastrophic expenditure' captured intensity as well as its incidence and also the degree of which catastrophic payments occur disproportionately among poor households. Measure of poverty impact also captured both intensity and incidence. The methods applied with data on out-of-pocket payments from the Urban Household Expenditure Survey Incidence and intensity of catastrophic payments - both in terms of total household consumption as well as ability to pay - increased between 1997 and 2002, and that both incidence and intensity of 'catastrophic expenditure' became less concentrated among the poor, but more concentrated in 2001 than in 1997. The incidence and intensity of the poverty impact of out-of-pocket payments increased between 1997 and 2002. Health security system may not have provided financial protection against catastrophic health expenditure to low-income households, because of high user fee policy not considering income level. The policies alleviating catastrophic health payments among the poor need to be more developed, and two threshold approaches further evaluated on our policy context.
