Adult echinostomes having 37 collar spines collected from the intestine of Pitalah ducks in Aceh Province, Indonesia in 2018 were morphologically and molecularly determined to be Echinostoma miyagawai Ishii, 1932 (Digenea: Echinostomatidae). Among 20 ducks examined, 7 (35.0%) were found to be infected with this echinostome, and the number of flukes collected was 48 in total with average 6.9 (1-17) worms per duck. The adult flukes were 7.2 (6.1-8.5) mm in length and 1.2 (1.0-1.4) mm in width (pre-ovarian or testicular level) and characterized by having a head collar armed with 37 collar spines (dorsal spines arranged in 2 alternating rows), including 5 end group spines, and variable morphology of the testes, irregularly or deeply lobed (3-5 lobes) at times with horizontal extension. The eggs within the worm uterus were 93 (79-105) ㎛ long and 62 (56-70) ㎛ wide. These morphological features were consistent with both E. miyagawai and Echinostoma robustum, for which synonymy to each other has been raised. Sequencing of 2 mitochondrial genes, cox1 and nad1, revealed high homology with E. miyagawai (98.6-100% for cox1 and 99.0-99.8% for nad1) and also with E. robustum (99.3-99.8% for nad1) deposited in GenBank. We accepted the synonymy between the 2 species and diagnosed our flukes as E. miyagawai (syn. E. robustum) with redescription of its morphology. Further studies are required to determine the biological characteristics of E. miyagawai in Aceh Province, Indonesia, including the intermediate host and larval stage information.

Objectives: This study aimed to investigate the factors associated with unmet dental needs among adults with activity limitations. Methods: Data were obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 945 adults aged 20 years or older with limited activity. Logistic regression analysis was used to examine the influence of predisposing, enabling, and need factors on unmet dental needs. Results: The proportion of adults with unmet dental needs during the last year was 52.2% in the middle-aged group and 45.5% in the older adult group. Higher household income was associated with fewer unmet dental needs in both groups. In the older adult group, married people were less likely to have unmet dental needs. In the middle-aged group, adults who perceived their oral health as poor were more likely to have unmet dental needs. Conclusions: All three factors (predisposing, enabling, and need) were found to be associated with unmet dental needs among adults with activity limitations. Special efforts should be made to improve access to dental care services for middle-aged adults with activity limitations.

Primary school is regarded as an important period when many health-related behaviors and life-styles begin to be formed. Acquiring them through school heath education has a strong influence on the health promotion of not only the family but also the community. The objectives of this study were to evaluate current oral health care of elementary schools in Chungnam province and to provide information for further development in elementary school oral health. We performed a questionnaire survey to 280 health teachers and among them, 155 teachers answered. The result of this study were as follows: 1. Sixty five percent of the health teachers had little interest in oral health. Major information sources for teaching oral health were books in 58.1% of the 155 teachers and 83.2% of teachers spent 30 minutes to 1hour per day in oral health care practice for the students. 2. Contents of the oral health education were composed of regular and special curriculums, and an average of education time during a semester was 2.6 hours in 3rd grade, and 1.3 hours in first and second grade. 60.6% of the teachers made the children practice the proper method of tooth brushing during the education time. 3. Major problems in oral health education were insufficient time, lack of equipment and difficulty in teaching method. The educational media were tooth models among 91.0% and OHP among 85.2% of the teachers. The tooth model was usually used in first to fourth grades and OHP in fifth to sixth grades. But 63.9% health teachers need to develop stronger educational methods using multimedia. 4. Meanwhile the most important strategy of oral health in urban schools was health education, that of rural schools was fluoride mouth-rinsing programme. Fluoride mouth-rinsing programmes were performed by 60.0% of the elementary school. Periodic dental examination was performed in all elementary schools. 98.2% of the schools sent the results home through school notification letters, but post-examination management was performed in only 67.1% of them 64.5% of the health teachers do follow-ups on the oral disease of the children after the examination. Only 0.7% of the schools have oral health education plans for the students' parents. Considering these major strategies for elementary school oral health care were health education, practicing proper methods of tooth brushing, periodic dental examinations, and fluoride mouth-rinsing programmes. But health teachers need more time for oral health education, practicing and management, and developing education materials. With regard to the high demand for oral health education and poor follow-up after periodic examination, the oral health education in elementary school should be considered as a formal educational course for more proper management of oral health, including application of major strategies to the children in earlier grades and efforts for increasing recognition and participation of the parents.

Objectives: The inherent nature of the Korean National Health and Nutrition Examination Survey (KNHANES) design requires special analysis by incorporating sample weights, stratification, and clustering not used in ordinary statistical procedures. Methods: This study investigated the proportion of research papers that have used an appropriate statistical methodology out of the research papers analyzing the KNHANES cited in the PubMed online system from 2007 to 2012. We also compared differences in mean and regression estimates between the ordinary statistical data analyses without sampling weight and design-based data analyses using the KNHANES 2008 to 2010. Results: Of the 247 research articles cited in PubMed, only 19.8% of all articles used survey design analysis, compared with 80.2% of articles that used ordinary statistical analysis, treating KNHANES data as if it were collected using a simple random sampling method. Means and standard errors differed between the ordinary statistical data analyses and design-based analyses, and the standard errors in the design-based analyses tended to be larger than those in the ordinary statistical data analyses. Conclusions: Ignoring complex survey design can result in biased estimates and overstated significance levels. Sample weights, stratification, and clustering of the design must be incorporated into analyses to ensure the development of appropriate estimates and standard errors of these estimates.

Objectives : The purpose of our study was to examine the relationship of oral health status such as dental caries and the performance of dietary action guides with six items. Methods : Oral examination and self-administrated questionnaire were conducted on 87 disabled students, aged 6-19 who were attending special school in the area of the metropolitan Seoul. Two logistic regression models to estimate odds ratios and 95% confidence intervals were used to investigate the association dental caries experience and the performance of dietary action guides after controlling for potential confounders. Results : The proportion of study subjects with caries were 37.9%, 26.9%(male) and 54.3%(female), respectively(p<0.05). There was significantly difference the subjects with caries and perceived oral health status(p<0.01). Among the dietary action guides items, skipping breakfast and not avoiding waste food were significantly higher in the proportion of subjects' caries(p<0.05, p<0.01, respectively). The avoiding waste food groups had more possibility of having caries significantly(p<0.05), even after controlling gender, and perceived oral health status. Conclusions : These results indicate that oral health promotion policy with dietary action guides should be strengthened for support of disabled student's dental health.

This study investigated and tested the overall level of dietary habits and health status/health management of the residents in a rural area. The interview survey was performed in March 2004 with a structured questionnaire to 510 residents who lived in Muan-Gun of Jeonnam province. The questionnaire was the abridged Scale of Dietary Habits and Health Status which surveys the morbidity, subjective health status, health management, and health examination. The Chi-squire method was used for some of the cross-sectional data. The 510 adult respondents were composed of 61.2% male and 38.3% female. In regularity of meal time, 56.3% of the subjects had a meal regularly(eating time), while 73.5% had a balanced diet(eating number). The habit of regular meal time was significantly higher in old people than in young people. The majority of the subjects had an appropriate meal amount. Unbalanced diet was higher in young people than in old people. 51.4% had the dining out and was significantly higher in younger people than in old people. In other questions, 60.7% of the subjects took a snack, 77.3% were under regular health management, and 49.6% had health examination. A minority of the respondents (31.3%) had disease, while 13.5% chronic disease, and 17.8% had acute disease. The level of dietary habits and general characteristics were positively correlated with each other, as were habits and health status. These results suggest the need for nutritional education programs directed at young people with a special emphasis on regularity of meal time. unbalanced diet, dining-out and a snack.

Community drinking water (CDW), mostly naturally flowing groundwater, plays important roles in supplying drinking water for urban and rural residents in Korea. Over 1,600 CDW facilities are distributed throughout the country, many of them situated in the outskirts of metropolitan cities. A large proportion of Korean people have become dependent on CDW for drinking due to a distrust of piped water's quality and a strong belief in the special medicinal effects of some CDWs. However, administrative and official management and the control of CDW facilities have been inadequate when compared with the strict examination and control of commercial bottled water, which is physically treated groundwater from deep bedrock aquifers. In this study, even though signs of anthropogenic contamination were not generally found, the tested chemical compositions of selected CDWs featured high enrichment of some constituents including Ca, Mg, Na, and HCO3 with natural origins such as water-rock interactions. Careless consumption of particular CDWs, which has no scientific basis, will not guarantee health improvement. Consequently, more intensive management of CDW facilities and a long-term interdisciplinary examination of the health effects of CDWs are needed to effectively protect people's health.
