Objectives: The purpose of this study was to confirm job satisfaction, job performance, and turnover intention according to dental hygienists' clinical assistance and preventive work. Methods: The collected data (N=380) were analyzed with independent t-tests and Pearson correlations using SPSS Statistics ver. 21.0 (IBM Co., Armonk, NY, USA). Results: The results indicated that the higher the overall job satisfaction of the dental hygienist, the higher their job performance and the lower their turnover intention (p<0.05). The results of the comparison of job satisfaction showed that preventive work was higher than dental hygienists' clinical assistance in all items except "I was pleased with work" (p<0.05). The results of the comparison of job performance showed that preventive work was higher than dental hygienists' clinical assistance in all items except "I have never complained, even if things go wrong" (p<0.05). The results of the comparison of turnover intention showed that clinical assistance was higher than dental hygienists' preventive work in all items (p<0.05). Conclusions: Our results demonstrate that job satisfaction, turnover intentions, and job performance have positive effects for preventive work. Therefore, dental clinics need to improve the actual environment so that dental hygienists can focus on preventive work.

Objectives : In Oriental Medicine, hyperlipidemia is considered as phlegm retention (痰飮) and blood stasis (瘀血). Typhae pollen helps remove blood stasis and hemorrhage, and it also has an effect of relieving pain caused by blood stasis. The purpose of this study is to investigate the preventive effects of Typhae pollen on diet-induced hyperlipidemia in rats. Methods : Thirty-two male Sprague-Dawley rats were divided into normal, control and treated groups. The control and treated groups were fed with a 1.5% cholesterol diet over 4 weeks, and extract of Typhae pollen was administered to the treated group during the same period. Blood samples were collected from each animal at 0 and 4 weeks and used for the blood chemical analysis. Animals were sacrificed at 4 weeks and chemical analysis was performed on the collected liver samples. Results : The serum total cholesterol ($122.45{\pm}4.96mg/dL$), LDL-cholesterol ($54.27{\pm}4.95mg/dL$), and triglyceride ($122.00{\pm}7.33mg/dL$) values of the treated group were significantly lower compared with the serum total cholesterol ($147.91{\pm}7.22mg/dL$), LDL-cholesterol ($81.91{\pm}8.34mg/dL$), and triglyceride ($169.27{\pm}12.34mg/dL$) values of the control group. The liver total cholesterol (TEX>$230.18<{\pm}18.81mg/dL$) values of the treated group were significantly higher compared with the liver total cholesterol ($178.54{\pm}$10.11mg/dL) values of the control group. Conclusions : On the basis of these results, it is confirmed that Typhae pollen has preventive effects on diet-induced hyperlipidemia in rats.

Methylmercury is a hazardous substance that is of interest with regard to environmental health, as inorganic mercury circulating in the general environment is dissolved into freshwater and seawater, condensed through the food chain, ingested by humans, and consequently affects human health. Recently, there has been much interest and discussion regarding the toxicity of methylmercury, the correlation with fish and shellfish intake, and methods of long-term management of the human health effects of methylmercury. What effects chronic exposure to a low concentration of methylmercury has on human health remains controversial. Although the possibility of methylmercury poisoning the heart and blood vessel system, the reproductive system, and the immune system is continuously raised and discussed, and the carcinogenicity of methylmercury is also under discussion, a clear conclusion regarding the human health effects according to exposure level has not yet been drawn. The Joint FAO/WHO Expert Committee on Food Additives proposed to prepare additional fish and shellfish intake recommendations for consumers based on the quantified evaluation of the hazardousness of methylmercury contained in fish and shellfish, methylmercury management in the Korea has not yet caught up with this international trend. Currently, the methylmercury exposure level of Koreans is known to be very high. The starting point of methylmercury exposure management is inorganic mercury in the general environment, but food intake through methylation is the main exposure source. Along with efforts to reduce mercury in the general environment, food intake management should be undertaken to reduce the human exposure to methylmercury in Korea.

Objectives: Waste treatment by incineration is gradually increasing as the emission of harmful substances has decreased owing to developments in incineration technology. However, residents living near incinerators continue to express anxiety regarding the effects on their health. Therefore, we attempted to summarize the health impact of incinerators by comprehensively reviewing the recently reported literature. Methods: Sixty-two epidemiological research papers related to incineration and health effects were selected from the Google Scholar database and analyzed (from between January 2001 and December 2019). Results: When compared to older incinerators, newer incinerators established after 2000 are considered relatively safe in terms of health effects. Nevertheless, there have been some studies that have linked them to various diseases, such as malignant tumors including soft tissue cancer and non-Hodgkin's lymphoma, reproductive disorders, respiratory diseases, and more. In addition, incinerator workers and local residents are considered to be exposed to dioxins and some heavy metals from the incinerator. Since most studies included subjects exposed to older incinerators, it is difficult to apply these results to the health impact assessment of new incinerators. However, it is not appropriate to conclude that new incinerators made with state-of-the-art technology are safe, as chronic environmental diseases caused by hazardous substances tend to appear only after prolonged exposure. Conclusions: In terms of environmental health, it is necessary to continuously monitor the health effects of incinerators. Also, there is a need to develop a research methodology that can minimize various confounders in incineration-related epidemiological study.

The pathobiologic process of arterial stenosis following balloon angioplasty continues to be an enigmatic problem in clinical settings. This study investigates the ability of demethoxycurcumin, a curcuminoid isolated from Radix Curcumae, to attenuate balloon injury-induced neointima(NI) formation in the rat carotid artery. It was found that demethoxycurcumin induced inducible heme oxygenase(HO-1) expression and inhibited dose-dependently cellular proliferation in rat vascular smooth muscle cells. Perivascular application of demethoxycurcumin immediately following injury significantly reduced NI area and NI thickness 2 weeks post-injury. Interestingly, treatment with tin-protoporphyrin IX, a HO inhibitor, reversed the effects of demethoxycurcumin on NI formation. These results implicate demethoxycurcumin as a potent new therapeutic agent that is capable of reducing post-angioplasty arterial stenosis through induction of the HO-1 expression.

Purpose: This study was conducted to evaluate the effects of an osteoporosis prevention health education on know ledge, health beliefs, self-efficacy and preventive health behaviors of women in an urban area. Methods: A one- group pre-test-post-test design was conducted to identify the effects of an osteoporosis prevention health education. The study was conducted between April and November 2008, and recruited 98 women in Seoul. All participants completed the pretest and posttest measures with self-administered questionaire: Osteoporosis Knowledge Test, Osteoporosis Health Belief Scale, Osteoporosis Self-Efficacy Scale and Osteoporosis Preventive Health Behaviors Survey. Results: The result of the paired t-test revealed statistically significant difference in the perceived susceptibility and perceived benefits of osteoporosis and osteoporosis preventive behaviors between pretest and posttest measures. However, the difference in knowledge and self-efficacy between the pretest and posttest measures was not statistically significant. Conclusions: These finding indicate the need for further health education to increase osteoporosis knowledge, health beliefs, self-efficacy and osteoporosis preventive health behaviors and provide guidance for developing effective osteoporosis prevention health education strategies.
