The purpose of this study is to explore effective factors of elderly people's overall death anxiety and sub-dimensions of death anxiety. The subjects were 156 elderly people in S City, Gyeonggi-Do gathered by convenience sampling. This study collected data by interviewing the elderly who agreed to participate in the study and then analyzed it using SPSS 12.0 through descriptive statistics, the t-test, F-test, Sheffe-test, correlation analysis, and multiple regression. The respondents' overall death anxiety score was 2.61(±.47), and 'anxiety in the dying process'(2.94) had the highest points among sub-dimensions. Effective factors of overall level of death anxiety among the elderly were 'age' (β=-.18, p=.015), 'education' (β=-.16, p=.045), and 'economic status' (β=-.26, p=.003). In sub-dimensions, the elderly who were female, relatively young, and had low economic status showed high 'anxiety in the dying process'. As for 'anxiety over what will happen after one's death', the elderly who were relatively young, and had low economic status had high scores. Finally, on 'the loss of existence', the elderly who had poor relationships with their families had high scores.

This study examines the fundamental frequency(f0) distribution of 2,740 Korean speakers in a dialogue speech corpus. Praat and R were used for the collection and analysis of acoustical f0 data after removing extreme values considering the interquartile f0 range of the intonational phrases produced by each individual speaker. Results showed that the average f0 value of all speakers was 185 Hz and the median value was 187 Hz. The f0 data showed a positively skewed distribution of 0.11, and the kurtosis was -0.09, which is close to the normal distribution. The pitch values of daily conversations varied in the range of 238 Hz. Further examination of the male and female groups showed distinct median f0 values: 114 Hz for males and 199 Hz for females. A t-test between the two groups yielded a significant difference. The skewness representing the distribution shape was 1.24 for the male group and 0.58 for the female group. The kurtosis was 5.21 and 3.88 for the male and female groups, and the male group values appeared leptokurtic. A regression analysis between the median f0 and age yielded a slope of 0.15 for the male group and -0.586 for the female group, which indicated a divergent relationship. In conclusion, a normative f0 distribution of different Korean age and sex groups can be examined in the conversational speech corpus recorded by a massive number of participants. However, more rigorous data might be required to define a relation between age and f0 values.

This research was conducted in order to examine the effect of tooth brushing room M elementary school in Changwon-city and to provide foundation data for effective project operation afterwards. The subjects were 347 students at the M elementary school where the tooth brushing room was being taught. The control group is 289 students at J elementary school where the tooth brushing room was not being taught. Research and analysis were carried out with structured survey and examination of decayed, missing, filled teeth (DMFT) index, decayed, missing, filled tooth surface (DMFS) index and O'leary index. The data was analysed by IBM SPSS Statistics ver. 19.0 program and the result is as follows: Depends on the tooth brushing room there was difference in statistical significance in filling teeth, sealant tooth surface, filling tooth surface, missing tooth surface, DMFS, O'leary index between the subject and control group. The less the frequency of brushing, the higher the DMFT index. Negative correlation was statistically significant. With incorrect brushing method, the less the frequency, the higher the DMFS index, Negative correlation was statistically significant. When the tooth brushing room was being implemented, O'leary index became low, negative correlation was statistically significant. As a result, in order to continue the effective operation of tooth brushing room, constant supervision and monitoring on students should be acutely needed by a principal, a school nurse and teachers in charge. Also together with a systemized cooperation between a health center and a nearby university's related majors departments, the research proposes to execute constant oral health education and to expand the implementation project of the tooth brushing room at nearby elementary schools.

The purpose of this study was to investigate the mediating effects of young children's playfulness between the children's peer competence and their mothers' play beliefs. For this study, 160 mothers and 160 children aged 4-5 years who were in kindergarten and daycare centers in Area J were selected. The collected data were analyzed based on correlation and mediation using SPSS Statistics. The research results are as follows. First, as a result of analyzing the relationship between the young children's peer competence and playfulness and their mothers' play beliefs, there was a statistically significant positive correlation between a mother's play-support beliefs and their children's peer competence and playfulness. On the other hand, the relationship between a mother's learning-support beliefs and her child's peer competence and playfulness was not significant. There was a significant positive correlation between playfulness and peer competence in the young children. Second, as a result of verifying the mediating effect of the children's playfulness in the relationship between their mothers' play-support belief and the children's peer competence, we found that playfulness has a partial mediating role.

The purposes of the study were to develop an instrument for family value and to identify the relationships of family value, family hardiness, and family adaptation by appling the family value scale to family with cancer children. The study was conducted in three phases. 1) A survey was conducted from July 20 to August 20, 1999 and 18 items of general family value scale was modified from the data of 153 fathers and 164 mothers. 2) In-depth interviews were made with 29 parents of cancer children from April 20, 1998 to May 20, 1999 to develop family value scale with cancer children, and 12 statements were developed. 3) The final survey was conducted from July 18, 2000 to August 30, 2000 and the data from 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics were analyzed to identify the relationships of the concepts. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, and Regression for path analysis. The study findings are as follows. The psychometric testing of general family value scale was Cronbach's alpha = 0.78. The reliability of the family value scale with cancer children showed the reliability as Cronbach's alpha = 0.73. Demographic characteristics showing significant correlations were cancer children's age, period of illness, period after completing treatment, mother's age, mother's education level, monthly income, payment type, confidence with health professional, and severity of children's illness. The correlation coefficients among major variables showed that family stressor was positively related with family strains(r=0.33, p<.001), and negatively related with family hardiness(r=-0.21, p<.001). Family strains was negatively related with family hardiness(r= -0.41, p<.001) and family adaptation(r=-0.46, p<.001). Correlations of family hardiness was positive with family value with cancer children(r=-0.31, p<.001), and negative with general family value(r=-0.16, p<.01). Family hardiness was positively related with family adaptation(r=0.35, p<.001). The causal relationship between study variables showed that family strains predicts general family value(γ=0.12, t=2.02), family value with cancer children predicts family hardiness(γ=0.31, t=6.30), family strains predicts family hardiness(γ=-0.40, t=-7.70), family value with cancer children predicts family adaptation(γ=-0.23, t=-4.11), and family hardiness predicts family adaptation(γ=0.43, t=7.78).

The purpose of this study was to investigate Staphylococcus epidermidis contamination on hands of 20 dental hygienists and 140 equipment surface of 20 dental clinics in a local area, from July to August 2017. The degree of S. epidermidis contamination was measured using a hand plate and a rodac plate and then cultured at $35^{\circ}C$ for 24 hours. Based on hand plate criteria, hand contamination was classified into low, middle, and high groups. Analysis of the variance (ANOVA) of the contamination level of the hand parts of the group surface contamination level of the dental clinic equipment was descriptive statistics after clustering lock count. S. epidermidis contamination was moderate in 55% of the hands of dental hygienists. The area of contamination was 29.45 colony-forming units (CFU) on the palm, followed by the middle finger 7.8 CFU, ring finger 6.4 CFU, and thumb 6 CFU. Medical equipment surface contamination was showed that 3-way handle 4.45 CFU, computer mouse 3.37 CFU, mirror handle 1.60 CFU were higher than other areas. The group with high hand contamination had a high positive correlation with the S. epidermidis contamination of the hand. S. epidermidis contamination level was higher on hands than on the medical equipment surface contamination. Therefore, medical staff should recognize the importance of hand hygiene which should be practiced in the manner suggested by World Health Organization. In addition, the medical team needs to be responsible for performing infection control tasks, implementing infection management guidelines and providing systematic education on infectious disease management.
