The purpose of this study was to examine the relationship of the self-rated peridontal health status of dental patients and the type of their treatment(implant, orthodontic treatment and general treatment) to the quality of life(happiness index), to investigate influential factors for oral health, and ultimately to provide some information on the development of oral health care programs geared toward boosting the happiness index. The subjects in this study were the patients who visited dental hospitals and clinics in Busan and South Gyeongsang Province. As for relationship between the field of treatment and the happiness index, the patients who received orthodontic treatment scored higher in both each itemand all the five items, and the patients who received implant treatment scored lower. Regarding links between self-rated periodontal health status and the happiness index, the patients who had no oral symptoms scored higher in both each item and all the five items, and the respondents whose self-rated health status and self-rated oral health status were both very good scored higher in the happiness index. The preparation of oral health programs that aim to improve the self-rated oral health of patients who visit dental hospitals or clinics is required.

The purpose of this study was to examine the impact of the oral health behavior and self-rated oral health of workers on their happiness indexes in an attempt to provide information on oral health planning geared toward industrial workers. The subjects in this study were 294 workers in North Gyeongsang Province. As a result of analyzing the relationship between their health behavior and happiness indexes, the workers who got regular health checkups had higher happiness indexes for both single items(p=0.002) and entire five items(0.012), and those who had their teeth cleaned over the past year had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.003). As for a toothbrushing frequency, the respondents who brushed their teeth more frequently had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.023), and those who had ever received oral health education had higher happiness indexes for both single items(p=0.041) and entire five items. The workers who kept their toothbrushes at work had higher happiness indexes for both single items(p=0.001) and entire five items, and the respondents who could afford to visit a dental clinic immediately in case of having a toothache had higher happiness indexes for both single items(p<0.001) and entire five items(p<0.001). The findings of the study suggest that the preparation of systematic oral health programs is required to boost the happiness indexes of industrial workers.

건강한 수생태계 유지·관리를 위하여 다양한 수생생물을 활용한 각 분류군의 종별 서식지 적합도 지수 DB 구축의 필요성이 증대되고 있다. 대부분의 수생생물의 경우 문헌 연구를 통해 서식지 적합도 지수를 산정하기는 어려우므로 현장 모니터링 자료를 이용한 어류, 저서생물 등의 서식지 적합도 지수를 산정하여 하천 복원 및 수생생물의 서식에 필요한 생태유량 결정에 중요한 인자로 활용하고 있다. 국내에서 하천 건강성 평가 등을 통해 수계별 다양한 조사를 수행하고 있으나 대부분의 연구는 출현 종 분류 및 출현율 등에 국한되어 있다. 또한, 부족한 현장 모니터링 자료로 인해 서식지 적합도 지수를 산정하기 위한 객관적이고 과학적인 물리적 인자를 도출하기 어려운 실정이며, 이는 전문가의 경험을 바탕으로 한 주관적 판단으로 이어져 결과의 신뢰성 측면에서 한계가 있을 수 있다. 따라서, 수계별 장기적인 모니터링 및 자료 구축을 위한 연구가 필요하며, 기존 서식지 적합도 지수 산정에 관한 방법의 장단점을 명확히 파악하여 국내 하천환경 및 특성에 적합한 서식지 적합도 지수 구축이 반드시 선행되어야 할 것이다.

The purpose of this study was to examine the self-rated oral health status and oral health concern of 6,094 adults over the age of 19, which were both related to subjective oral health awareness, based on the second-year (2008) raw data of the 4th National Health and Nutrition Survey. 1. As for subjective oral health awareness, 49.4 percent replied they were in bad oral health when they were asked about self-rated oral health status. Regarding oral health concern, 62.6 percent answered they were sort of concerned about oral health. 2. As to oral health indexes by sociodemographic characteristics, there were statistically significant differences in oral health indexes according to gender, age, academic credential, monthly mean household income, frequency of eating between meals and toothbrushing frequency. Smoking made no statistically significant differences to oral health indexes (p<0.000). 3. Concerning self-rated oral health status by sociodemographic characteristics, no significant differences were found according to gender, age and academic credential, and there were statistically significant differences according to monthly mean household income and smoking (p<0.000), frequency of eating between meals (p<0.018), toothbrushing frequency (p<0.003). 4. In relation to oral health concern by sociodemographic characteristics, gender and smoking made no significant differences, and statistically significant differences were found according to age (p<0.003), academic credential, monthly mean household income, frequency of eating between meals and toothbrushing frequency (p<0.000). 5. In regard to the relationship between subjective oral health awareness and oral health indexes, none of the oral health indexes had a significant relationship to self-rated oral health status, and there were statistically significant differences in oral health concern according to functioning teeth index (p<0.011) and community periodontal index (p<0.017).

This study analysed the income-related health inequality of the aged in Korea applied to EQ-5D. Two decompositions were used in analysis. One was the decomposition of income-related health inequality into six different dimensions of EQ-5D, and the other was to decompose it by sub-group such as sex, region, existence of spouse. The results are summarized as follows. First, the health concentration index(CI) of the aged was .0254, which meant that there were pro-rich inequality in elderly people's health levels. The same patterns were also seen in the analysis of different dimensions of EQ-5D such as mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Second, mobility accounted for 35.8% of total EQ-5D score, most contributing to CI of the dimensions of EQ-5D. The CIs by the dimensions ranged from .0091 for mobility to .0013 for self-care. Third, The decompositions by sub-groups showed that the contributions of sex, region, and existence of spouse to health inequality was similar to each other, all of three sub-groups accounted for 10 % of inequality respectively. Fourth, the inequality within group was higher in female group, rural area, and the aged without spouse. The average health level of these groups was lower than that of the other ones, too. These facts indicated that old women, the aged without spouse, and the elderly in rural area were the most vulnerable groups in health problems. Therefore, it is necessary to pay more attention to health problems of these groups in the policy making of health security and social welfare services.
