This study was undertaken to identify factors affecting the mental health of nursing students, including career motivation, sense of humor, and problem-solving ability, and to provide data for improving mental health of nursing students. This research enrolled 235 nursing students in B and Y cities. Data were collected from October 22 to October 31, 2018, and analyzed by applying t-test, ANOVA, Pearson's correlation coefficient, and multiple regression, using the SPSS/WIN 22.0. The average score for mental health was determined to be 2.19±0.77. Ed. Negative correlation was obtained between mental health and career motivation (r=-0.443, p<0.001), mental health and sense of humor (r=0.400, p<0.001), and mental health and problem-solving ability (r=0.465, p<0.001). Regression analysis showed that 33.4% variance in the mental health of nursing students is affected by gender (β=-0.121, p=0.033), pocket money (β=0.123, p=0.028), peer relation (β=0.165, p=0.004), sense of humor (β=-0.168, p=0.012), and problem-solving ability (β=-0.186, p=0.006). Data from this study indicates a necessity to repeat the study for identifying general characteristics and psychological factors that control an individual, and technical factors that can be acquired through learning. Taken together, we believe that the factors included and indicated in this study influence the mental health of nursing students.

This study conducted a survey of 249 adults to determine the effect of oral health beliefs on total body health by mediating subjective oral health. The results showed that the subject's oral health belief averaged 3.75 points, the component of oral health belief was 3.41, the severity 3.73, the importance 4.22 and the benefit 4.19, and the subjective oral health was 3.77 points and the overall health was 3.06. Oral health belief and subjective oral health were found to have a correlation of wealth (r=-0.54, p<0.001), oral health belief and total body health also had a correlation of wealth(r=-0.30, p<0.001), subjective oral health and total body health had a relationship of justice(r=0.47, p<0.001). It was also found that oral health beliefs affect total body health by fully mediating subjective oral health. Based on these findings, it is thought that oral health education programs for adult oral health beliefs can be developed and utilized as basic data for comprehensive general health care, including oral health care, based on correct knowledge and attitudes.

Objectives : The purpose of this study was to investigate the number of remaining natural teeth in elderly people visiting dental care services and the factors affecting dental visit. This study will contribute the development of oral health promotion programs for the elderly people. Methods : Subjects were 172 elderly people recruited from 217 senior citizens visiting public oral health care services in 16 districts in Busan. They completed self-Corresponding Author reported questionnaires. Results : Elderly people had less remaining natural teeth (p<0.001). The remaining natural teeth ($15.07{\pm}8.75$) of the health insurance beneficiary were majority than those of the medicaid ($8.78{\pm}8.45$)(p<0.001). The respondents with better oral health condition had more remaining natural teeth (r=0.317, p<0.001), and those who were more worried about oral health had less remaining natural teeth (r=-0.599, p<0.001). Aging accelerates loss of natural teeth (p<0.001) of 3.203. Approximately 2.188 remaining teeth will be preserved by oral health care improvement (p=0.009). Conclusions : Frequent dental clinic visit will prevent natural teeth loss in the elderly people. Toothbrushing is the most efficient method of oral health care in the elderly people. Awareness towards oral health care is the motivation to preserve natural teeth in the elderly people.

Recently, significant contamination problems by residual chemicals have occasionally been occurred from major rivers and drinking water in Korea. Therefore, the management for use of them and risk assessment should be more strictly performed. In this study, we have analyzed trihalomethanes in treated water samples taken from water plants located in the region of four major rivers (i.e. Han river, Geum river, Youngsan river and Nakdong river) in Korea for eight years (1997～2004). From the data, we could assess the excess cancer risk by calculating the chronic daily intakes (CDI) multiplied by individual oral slope factors, Q₁＊, for the cancer suspected matters such as trihalomethanes, moreover the hazard index which is calculated by dividing the CDI by the acceptable daily reference dose (R/sub f/D) was determined for the risk assessment. As a result, in the case of 95 percentile excess cancer risk, it was shown that the excess cancer risk for dichlorobromomethane in the Nakdong river region is highest among the tested samples as 8.73 x 10/sup -6/. The 95 percentile total hazard index (the sum of individual hazard indices considering R/sub f/D), in addition, was below 1.0 for all samples, and therefore it was assessed that water samples taken from treatment plants of four major rivers are not harmful.

The purpose of this study is to gather biofilm of unit chair waterline in the laboratory, to analyze microorganisms, to apply the existing draw-off method and the method of using disinfectant, and to compare the change of the number of microorganisms. The water was provided by the waterline of the unitchair, and the gathered samples were cultured with the use of R2A agar plate. Bacterial species separated through the identification of microorganisms were analyzed. To identify the decrease of microorganism for draw-off, samples were gathered in the intervals of 30 seconds, 60 seconds and 120 seconds, and to identify the effect of disinfectant, samples after disinfection were gathered. The quantitative comparison of microorganisms through the gathered samples was done by SPSS program. The number of identified bacteria are 8 species, most of which are gram-negative bacterium, and Sphingomonas type. The rapid decrease of the number of microorganism through draw-off for 60 seconds was confirmed, and microorganisms after disinfection weren't detected right away. Based on the method and result of this study, the water pipe of unit chair, which can be neglected easily, can be managed, so cross infection can be prevented, and systemic management can be possible.

This research presents a methodology to define and apply appropriate index that can measure the risk of regional flood damage. Pressure-State-Response structure has been used to develop the Flood Risk Index(FRI), which allows for a comparative analysis of flood risk assessment between different sub-basins. FRI is a rational assessment method available to improve disaster preparedness and the prevention of losses. The pressure and state index for flood at 117 sub-basins from the year 1980s until the t 10s showed proportional relations, but state index did not decrease even though response index increased. This shows that pressures for flood damage relatively exceed countermeasure for flood. Thus this means we need to strengthen design criteria for flood countermeasure in the future. The FRI is gradually going down in consequence of continuous flood control projects. Flood risk of Han River and Nakdong River area is relatively lower than that of Geum, Seumjin, and Youngsan River area.
