송애희,정은주 한국융합학회 2018 한국융합학회논문지 Vol.9 No.9

본 연구는 19세 이상 비만자를 대상으로 구강건강 상태와 행태를 분석하여 관련 요인을 알아보고자 실시하였다. 국민건강영양조사 제6기 3차의 원시자료를 활용하여 5,632명을 체질량지수에 따라 저체중, 정상, 과체중으로 분류하여 비만 도에 따른 음주, 흡연, 구강건강상태와 행태에 대한 관련성을 복합표본 교차분석과 복합표본 로지스틱 회귀분석을 실시하 였다. 결과는 남자, 60대, 저소득층, 교육수준이 낮고, 기혼에서 비만도가 높았으며, 비만자일수록 치주질환 유병이 높았고, 주관적 구강건상 상태가 더 나쁘다고 인지하는 것으로 나타났다. 이런 결과를 고려한 연구는 비만성인의 구강건강 향상에 도움이 될 프로그램 개발에 도움이 될 것으로 판단된다. 따라서, 비만 성인에 맞는 맞춤형 구강교육 프로그램의 개발을 통한 정기적인 교육으로 구강건강상태와 행태를 개선하기 위한 동기유발이 필요할 것으로 사료된다. This study was conducted to analyze oral health conditions and behaviors of obese people over the age of 19 to identify relevant factors. Using the data of the 6th Korean National Health and Nutrition Examination Survey, 5,632 people were classified by body mass index(BMI). The relationship between drinking, smoking, and oral health status and behavior according to obesity index was analyzed by X2-test and logistic regression analysis. Results showed that men, 60s, low income, low education level and in marriage group were high in obesity. Obese people were related with higher prevalence of periodontal disease and perceived subjective oral health status to be worse. This study will contribute to the development of programs to improve oral health of obese adults. Therefore, it is necessary to induce motivation to improve oral health by regular education through development of customized oral education program for obese adults.

송애희,김화숙 한국융합학회 2017 한국융합학회논문지 Vol.8 No.9

본 연구는 제6기 국민건강영양조사 자료를 이용하여 사회경제적 요인, 치주질환 및 영구치 우식경험에 따른 구강건강의 격차를 확인하고, 구강건강 관련 삶의 질에 영향을 미치는 융합적 요인을 분석하여 정책 계획의 기초자료를 제시하고자 실시하였다. 연구 대상은 본인이 인지하는 구강상태에 응답한 7,639명으로 하였고, 분석방법은 복합 표본 교차분석과 로지스틱 회귀분석으로 시행하였다. 결과는 연령이 높고, 가구 소득과 교육수준이 낮을수록 주관적 구강건강이 나쁘고, 구강검사를 한 대상자는 구강건강을 좋게, 치주질환이나 영구치우식경험자는 구강건강을 나쁘게 인식하였다. 사회경제적 취약계층, 치주질환 경험자, 영구치우식경험자 등이 구강건강에 부정적임을 확인할 수 있었다. 따라서 이러한 구강건강의 불평등을 근본적으로 해결하기 위한 정책개발이 필요할 것으로 사료된다. The purpose of this study was to investigate factors affecting perceived oral health status according to socioeconomic status and community periodontal index(CPI) and decayed, missing, and filled teeth(DMFT) using the 6th Korean national health and nutritional examination survey(KNHANES Ⅵ) and provide a basic data for plan of policy. The higher the age, the lower the household income and education level, the worse the subjective oral health had better oral health and there was a tendency that the respondents who had no oral exam within 1 year and experienced CPI or DMFT estimated their own health as worse. It is needed to make policy development to resolve the inequality of oral health.

송애희,윤혜정 한국치위생학회 2019 한국치위생학회지 Vol.19 No.4

Objectives: In this study, both subjective and objective levels of oral health were used to identify the relationship between oral health inequalities. Methods: Korean National Health and Nutritional Examination Survey data from 2013 to 2015 were combined to create an analysis plan. Oral health questions categorized as subjective oral health conditions and oral health-related diseases used dental tissue disease status as data measured by the Community Periodical Index(CPI) and decayed, missing, filled teeth(DMFT) experience. Other data on oral health behaviors such as toothache experience, the frequency of toothbrush use, chewing problems, oral examination status, and unmet dental care needs were classified and analyzed according to the socioeconomic level. Data were analyzed using frequency and cross analyses, and the statistical significance level was set at 0.05. Results: It was found that higher the economic and educational level, better was the subjective oral health, lower the CPI, lower the experience of toothache, higher the frequency of toothbrush use, lower the number of people having chewing problems, and higher the frequency of oral checkups. Conclusions: Oral health inequality exists among social classes. It is suggested that continuous research and efforts be carried out to promote oral health while considering socioeconomic and educational levels. Further, active government efforts will be needed to address polarization by social class.

Vertical pumps are structurally weak in terms of vibration because of installed heavy motor on top of the pumps in form of cantilever. So high vibration on top of the pumps can occur with low vibration in the bottom. These vibration problems experienced very frequently. Majority of studies have been related to the unbalance of rotating parts or structural resonance. In this paper, we introduce an unusual case, vibration variation caused by VPF(Vane Passing Frequency) according to water level.

Objectives: This study aimed to investigate whether there was a connection between oral health and memory loss in elderly individuals with no abnormalities in their daily lives and to identify factors affecting memory loss. Methods: This study aimed to identify an association between the Geriatric Oral Health Assessment Index and Subjective Memory Complaints for the elderly individuals living in the community. Results: The results of analyzing the oral health assessment according to the general characteristics of the study participants revealed that with increase in age, income (p=0.05) and oral health of the elderly living alone decreased compared to those living together in the family (p=0.05). Moreover, the lower the income (p=0.05), the higher was the memory loss for the elderly living alone than for the elderly living together with their family (p=0.05). Conclusions: The study identified a link between oral health of the elderly and subjective memory loss and observed that oral health, cohabitation, and income level were related to subjective memory loss. Therefore, oral health should be considered as a predictor of memory loss for the elderly.

자려 평형 틸팅 패드 스러스트 베어링의 정렬불량에 따른 베어링 특성에 관한 실험적 연구

Self-equalizing tilting pad thrust bearings are usually employed in turbomachines to achieve high stability and reliability. A tilting pad bearing can incorporate self-equalizing links to handle the misalignment between the bearing and the thrust collar. In this popular design method, the pads sit on the upper-level plates and the lowerlevel plates stay on the retainer base. With misalignment, the pads that are heavily loaded are pushed down. Consequently, the link pushes up the pads on the opposite side, keeping the bearing surface parallel to the thrust collar surface. The self-equalizing link is used to handle the misalignment from the thermal and mechanical effects. In this study, the experimental investigation deals with the performance of self-equalizing tilting pad thrust bearings. The test rig for evaluating the performance of bearing is developed which can control the misalignment angle. Simultaneous measurements are taken for the force acting on each pad. Pad metal temperature and oil film thickness are functions of the shaft speed, bearing load, misalignment angle, and design of leveling plates. The effect of misalignment on bearing performance is discussed. The results demonstrate that the load on each pad depends on the test conditions(especially misalignment angle), and the load influences the performance of bearings.

Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach``s alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(в=-0.410) had the influence on the oral health-related quality of life, nasal dryness(в=0.230), age(в=0.189), and halitosis (в=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.
