Objectives : The purpose of this study was to examine factors affecting the effective demand of workers for dental treatment in a bid to provide some information on the improvement of oral health. Methods : The subjects in this study were 255 workers who were engaged in the pharmaceutical industry. A self-administered survey was conducted, and the collected data were analyzed by a spss(statistical package for the social science) win 12.0 program to find out their demographic characteristics, oral health awareness, oral health behavior and factors for the choice of a dental institution. Results : 1. Concerning the level of oral health awareness, 47.0 percent were at a low level(0 to three scores), and 35.2 percent were at an intermediate level(four to six scores). 2. As to oral health behavior involving a daily mean toothbrushing frequency, they brushed their teeth 2.65 times per day on the average. The most widely utilized oral hygiene supply was mouth rinse. Regarding oral health status, 53.7 percent weren't in good dental health, and just 23.0 percent got a dental checkup on a regular basis. 45.8 percent of those who didn't get a dental checkup cited time constraints as the reason. 26.0 percent received oral health education, and 91.4 percent were aware of the necessity of a corporate incremental dental care system. 3. Marital status, age and the reliability of dental institutions made differences to their choice of a dental institution. 4. As for the relationship between oral health awareness and the factors for the choice of a dental institution, oral health awareness had a statistically significant positive correlation to the reliability of dental institutions. Conclusions : The above-mentioned findings suggest that oral health education enables workers to have a correct knowledge on oral health, to change their own oral health behavior and to make the right choice of a dental institution in consideration of their oral characteristics. They should be urged to get a regular dental checkup not to develop chronic oral diseases so that they couldn't have to receive first-aid dental treatment. To promote the oral health of workers, oral health care personnels available should be utilized, and the incremental dental care system should be more vitalized to cut down on their effective demand for dental treatment.

Objectives : The growing elderly population and social changes have fueled a rapid increase in demand for elderly care facilities, but health care services for the elderly, especially oral health services, have long been overlooked. The purpose of this study was to examine the oral health care of elderly residents in elderly care facilities in an effort to provide some information on the elderly's oral health care and the development of dental care programs geared toward institutionalized elderly people. Methods : The subjects in this study were 230 elderly people who were in elderly care facilities in Jeolla Province. An individual interview was held, and they got a dental checkup. As for data analysis, t-test and ANOVA were utilized, and Scheffe post-hoc test was employed. Results : 1. In relation to the subfactors of the quality of life related to oral health, the elderly people investigated got a mean of 4.58, 4.47, 4.38, 4.09, 3.94, 3.91 and 3.76 respectively in activity disorder, mental disorder, social disorder, mental inconvenience, functional disorder, physical pain and physical disorder. 2. Concerning the overall quality of life related to oral health, there were statistically significant gaps in this aspect according to gender, age, presence or absence of systemic disorder, presence or absence of eating difficulties, subjective health status, subjective oral health state and oral health concern. 3. The presence or absence of root caries had a significant relationship to physical pain and social disorder among the subfactors of the OHIP-14, but that had nothing to do with functional disorder, mental inconvenience, physical disorder, mental disorder and activity disorder. Conclusions : The oral health indexes of the institutionalized elderly people in Jeolla Province were measured, and what factors affected the subfactors of oral health was checked. As a result, there appeared a close relation ship between oral health and the quality of life. Therefore effective oral health plans that cater to the elderly should be carried out to improve elderly people's quality of life related to oral health who stay in long-term elderly care facilities. In the future, prolonged research should be implemented from diverse angles for the sake of institutionalized elderly people.

The purpose of this paper is to provide the basic information concerning school health nursing activities in schools lacking in a school nurse, and the degree of satisfaction of trainess to the training course of school health nursing. The data for this study were collected by means of questionnaire from 150 teachers(100 of primary school and 50 of middle school)who attended the training course superintended by the Board of Education of Kyeong Nam Province from July 27 to August 6 in 1987. The main results of this study can be summarized as following; 1. General characteristics of the trainees: The majority of the trainees (71.3%) were in the age of twenties, 86.5% graduated from four-year teachers' college, 63.5% had less than five-year experience as a teacher. 2. 60.5% of the trainees were actually offering school health nursing services. 67.8% decided voluntarily to participate in the training course, and 62.7% attended the course for the purpose of obtaining health knowledge. 3. Only 4.2% of schools established appropriate health organization, and 34.5% were equipped with nursing clinic. But the main reason school health nursing activities were not performed very well was the insufficient supply of needed medicines and related materials. 4. School health nursing services in schools lacking in a school nurse were offered mainly by the teacher holding additional job of school health. class teacher and atheletic teacher. But the sanitary management for school meal services and community health activities were not carried out at all in many schools. 5. As a whole, trainees were satisfied with training program. But some subjects of the course did not satisfy them because those ones were so theoretical without any practice. 6. Many trainees wished the training course to be more concentrated on case studies which are helpful to solve actual problems. 7. 75% of trainees answered to have decided to perform school health nursing activities more actively than before. 8. Any significant relationship can not be found between trainees' general characteristics and their attitude to school health nursing activities after the training course.

Concerns about growing health insurance expenditures became a national Issue in 2001 when the National Health Insurance went into a deficit. Increases in spending for ambulatory care shared the largest portion of the problem. Methods and systems to control the spending should be developed and a system to measure case mix of providers is one of core components of the control system. The objectives of this article is to examine the feasibility of applying Korean Diagnosis Related Groups (KDRGs) to classify health insurance claims for ambulatory care and to identify problem areas of the classification. A database of 11,586,270 claims for ambulatory care delivered during January 2002 was obtained for the study, and the final number of claims analyzed was 8,319,494 after KDRG numbers were assigned to the data and records with an error KDRG were excluded from the study. The unit of analysis was a claim and resource use was measured by the sum of charges incurred during a month at a department of a hospital of at a clinic. Within group variance was assessed by th coefficient of variation (CV), and the classification accuracy was evaluated by the variance reduction achieved by the KDRG classification. The analyses were performed on both all and non-outlier data, and on a subset of the database to examine the validity of study results. Data were assigned to 787 KDRGs among 1,244 KDRGs defined in the classification system. For non-outlier data, 77.4％ of KDRGs had a CV of charges from tertiary care hospitals less than 100％ and 95.43％ of KDRGs for data from clinics. The variance reduction achieved by the KDRG classification was 40.80％ for non-outlier claims from tertiary care hospitals, 51.98％ for general hospitals, 40.89% for hospitals, and 54.99% for clinics. Similar results were obtained from the analyses performed on a subset of the study database. The study results indicated that KDRGs developed for a classification of inpatient care could be used for ambulatory care, although there were areas where the classification should be refined. Its power to predict tile resource utilization showed a potential for its application to measure case mix of providers for monitoring and managing delivery of ambulatory care. The issue concerning the quality of diagnostic information contained in insurance claims remains to be improved, and significance of future studies for other classification systems based on visits or episodes is guaranteed.

Environmental tobacco smoke (ETS) or second hand smoke or passive smoking has become a well-known risk factor for various health hazards in nonsmoking adults as well as active smokers. In Korea, there have been few studies concerning about the impact of ETS on periodontal health. Therefore, the aim of this study was to investigate the association between exposure to passive smoking and prevalence of periodontitis using Korea National Health and Nutrition Examination Survey (KNHANES) in 2008 and 2009. The Fourth KNHANES data was employed from 2008~2009. The final sample size was 4,669 adults aged over 18 years, who were never-smoker and had the information about ETS both at home and in the workplace, urine analysis and periodontal examination by Community Periodontal Index (CPI). Periodontitis was defined as CPI codes ${\geq}3$. Data were analyzed using PASW Statistics 18.0. The sociodemographic and behavioral factors were adjusted as confounders. Overall, 17.1% (male 16.4%, female 83.6%) of the participants were exposed to ETS. The mean concentration of cotinine in those exposed ETS was significantly higher than that in unexposed people ($46.92{\mu}g/ml$ versus $19.34{\mu}g/ml$, p<0.001). Participants exposed to ETS were more likely to have periodontitis than those unexposed after adjusting for potential confounding variables. ETS is associated with the prevalence of periodontitis in Korean adults. This may suggest that patients with periodontitis or periodontal surgery should be protected from smokers or smoking places.

This study was performed to investigate and analyze users' needs for m-health based prevention and intervention programs that are intended to improve the awareness of metabolic syndrome and promote health behaviors of college students. A questionnaire survey was conducted to 200 college students of 2 university in D city. Data were analyzed using descriptive statistics, t-tests, chi-square test with the SPSS Version 20.0. The result showed that users wanted customization of prescriptions and accurate measurement of health applications, and provided a positive feedback on information exchange between those who manage their health. The most preferred content was proper exercise methods, and the preferred gamification factors were goal-setting, compensation, and competition. The optimal price for wearable devices was between 10,000 to 50,000 won, and calorie consumption function was also preferred. Although users with experiences of wearable devices and health apps had a higher knowledge score pertaining to metabolic syndrome, there was no significant difference in the overall score. Concerning the health behaviors associated with lifestyles, individuals without the experiences of wearable devices and health apps showed a remarkably lower score. The research has a significance that it investigated and analyzed the contents needed for the development of effective moblie health based prevention and intervention programs targeting the population in their early adulthood. Therefore, based on the findings, we propose a rich and concrete follow-up study on the needs and characteristics of different user types by collecting a population with experiences of wearable devices, and a development of differentiated mobile health based prevention and intervention programs.

Multi-omics data is difficult to interpret due to the heterogeneity of information by the volume of data, the complexity of characteristics of each data, and the diversity of omics platforms. There is not yet a system for interpreting to visualize research data on environmental diseases concerning environmental harmful substances. We provide MEE, a web-based visualization tool, to comprehensively explore the complexity of data due to the interconnected characteristics of high-dimensional data sets according to exposure to various environmental harmful substances. MEE visualizes omics data of correlation between omics data, subjects and samples by keyword searches of meta data, multi-omics data, and harmful substances. MEE has been demonstrated the versatility by two examples. We confirmed the correlation between smoking and asthma with RNA-seq and Methylation-Chip data, it was visualized that genes (P HACTR3, PXDN, QZMB, SOCS3 etc.) significantly related to autoimmune or inflammatory diseases. To visualize the correlation between atopic dermatitis and heavy metals, we selected 32 genes related immune response by integrated analysis of multi-omics data. However, it did not show a significant correlation between mercury in blood and atopic dermatitis. In the future, should continuously collect an appropriate level of multi-omics data in MEE system, will obtain data to analyze environmental substances and diseases.
