The purpose of this study was to analyze the effect of seasonal change in characteristics of hygiene activity on domestic hot water energy consumption. With 16 residents of 4 households, the data about frequency of hygiene activity and water temperature was collected from February to August, 2017. The results of collected data discovered that the frequency of hygiene activity was higher especially in summer, whereas the consumption of warm water they used was higher in winter. The seasonal change in characteristics of hygiene activity was analyzed to be changed and strongly influenced by outdoor temperature. The influence of characteristics of hygiene activity on hot water consumption was analyzed. There was 13% of difference between consumption that was calculated taking characteristics of hygiene activity into account and consumption that was not. Therefore, this study suggested hygiene activity schedule, hot water profile and hot water consumption pattern, which can be utilized for improving simulation as well.

Objectives: The purpose of this study was to investigate the degree of activity restriction and the number of remaining teeth of the elderly and to analyze the correlation. Methods: Statistical analysis of the collected data was analyzed using the SPSS window program 25.0 version (IBM) using a composite sample for the analysis of the 7th National Health and Nutrition Survey data, and a composite sample multiple logistic regression analysis was performed to confirm the effect of activity restrictions on the number of remaining teeth. Results: As a result of analyzing the effect of activity restriction on the number of remaining teeth, in the model that analyzed only activity restriction variables, the risk ratio of less than 20 remaining teeth was 1.61 times higher and the age-adjusted model, the risk ratio of less than 20 remaining teeth was 1.46 times higher (p<0.001). In the model that corrected all variables, the results were not statistically significant. Conclusions: In this study, the relationship between activity restriction and the number of remaining teeth could be confirmed, and in subsequent studies, more in-depth studies are considered to be needed using sub-variables that specifically reflect the reasons for activity restriction.

Objectives: The purpose of this study was to investigate role·activity factors, ideal·value factors stress and stress amount relationship in clinical practice of dental hygiene students. Methods: The participate in this study were 231 dental hygiene department students. the survey was conducted from August 24 to September 30, 2018, using a structured questionnaire(1040460-A-2018-036). The collected data were compared and analyzed using a ANOVA and multiple regression. Results: The factors affecting the amount of stress were investigated. Role and activity factors stress in case of too much assignment, repeat simple and funtional work, ideal and value factors stress in case of utilized as a subsidiary work practice institution rather than clinical practice, lake of awareness that the training institution is a trainee. Conclusions: School institution and departments form organic relationships with industries. Uniform training guidance for each training institution does not help with diversity or creativity and problem-solving skills. It gives some autonomy to the training guidance of training institutions, also a clear standard for the contents of the training. we need a system that can provide and evaluate basic guidelines for what students can do in clinical practice.

An appropriate amount of samples, collected from three each paddy forest, field and riverside soil near Taegu city, was suspended in sterile water and then diluted in order to isolation of antagonistic to oral cancer. The diluted samples were inoculated on separating medium in the routing spreading method. So, seven hundred and eighteen strains were isolated on HV agar and 220 strains were on methanol medium from soil samples. So, during the screening of anti-oral cancer activity from soil, we isolated microorganisms showing powerful antagonistic activity. Among them, No. 78 strain exhibited the most strongly anti-oral cancer activity. Microbiological properties were investigated by the methods described in the Bergey's Manual of Systematic Bacteriology and experimental methods of identification of actinomycetes by Hamada et al. As a result, a methylotrophic actinomycetes strain No. 79 was estimated as Amycolatopsis sp. based on taxonomic studies.
