This study was to investigate the level of serum lipids and obesity in housewives in Mooan, and relationships between them. The average age, height and weight were 51.1 years, 154.3cm and 58.3kg respectively. The level of obesity of subjects was higher than that of housewives in other areas investigated in other studies. BMI and RBW underestimated in the obese compared to BIA. The amounts of lean body mass and total body water of subjects above 60 years old were smaller than those of forties and their BMI and RBW were lower than those of forties. However, their body fat percentage was nearly same as that of forties. Serum HDL-cholesterol(HDL-C) of subjects was lower than 55mg/㎗, the lower limit of normal range. Triglyceride of subjects above 60years old was higher than the 95th percentile of those of the same age with reference to Mayo clinic. The serum total cholesterol(TC) showed positive correlation with LDL-cholesterol(LDL-C) and TC/HDL-C(p<0.001). LDL-C showed positive correlation with TC(p<0.001), but negative correlation with HDL-C(p<0.05). HDL-C showed negative correlation with triglyceride(p<0.05). TC/HDL-C showed a positive correlation with triglyceride(p<0.05). HDL-C was the serum lipid which showed the highest correlation with obesity and body composition. It showed a negative correlation with the percentage of body fat(p<0.001), total body fat(p<0.001), BMI(p< 0.05) and RBW(p<0.05). TC/HDL-C showed positive correlation with the percentage of body fat(p<0.01) and total body fat(p<0.05). As the result of above, it is needed to make more researches to find out the proper method to estimate the obesity of subjects and educate subjects in Mooan about nutritional information for obesity.

This study was conducted to identify the influence of clinical practice stress and communication skills on the ego-resilience of nursing students. The subjects were 122 nursing college seniors in B city who have experience in clinical practice. Data were collected from March 23 to 30, 2015, and analyzed by the t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients and multiple regression. It was found that there were significant differences in the ego-resilience depending on the gender, satisfaction with nursing major and relationships among fellow students during clinical practice. There was a significant positive correlation between ego-resilience and communication skills. The meaningful variables which influence the ego-resilience were communication skills, satisfaction with nursing major, relationships among fellow students during clinical practice and gender. These factors were responsible for 38.9% of the total variance in the ego-resilience of the nursing students, and communication skills were the most influential factor. In conclusion, to increase the ego-resilience of nursing students, it is necessary to develop effective communication training programs and strategies to improve their satisfaction with the nursing major and relationships among fellow students during clinical practice.

This study was conducted to identify actual dental care status, levels of knowledge, attitudes, and behaviors about dental health, and dental health conditions in elementary students; and examine the relationships between the levels of knowledge, attitudes, behaviors, and dental health conditions for 427 students in their sixth grades from six elementary schools in Pusan area from November 1st to December 5th, 2002. The data was collected through a structured study questionnaire and through dental checkups by dentists and was analyzed into frequency, percentage, mean, standard deviation, t-test, one-way ANOVA and Pearson's correlation analysis using SPSS program. The main results of this study were summarized as follows： 1) The levels of knowledge, attitudes, behaviors about dental health was found to be high as mean score 18.75 points (64.7％) in knowledge, 17.86 points (59.5％) in attitudes, and 31.64 points (67.3％) in behaviors. Therefore they were found to care a lot about their dental health. The indices of dental health conditions were found to be low as mean score 0.87 pieces (3.1％) of treated teeth, 1.27 pieces (4.5％) of teeth to be treated, 7.64％ of the DMFT rate and 0.43 points (7.2％) of the simplified oral hygiene index. Therefore their condition of dental health was found to be very clean. 2) The relationships among the knowledge, attitudes, and behaviors about dental health showed a weak level of positive correlations. Among the conditions of dental health, treated teeth and the DMFT rate showed a moderate level of positive correlation； and treated teeth and the simplified oral hygiene index showed weak level of positive correlation. 3) The condition of dental health of the subjects of this study was found to be good and dental care was properly done when there was participation of parents and school health educators in dental care. It tells us that dental education is required not only for children but also for their parents. As there were significant correlations between knowledge, attitudes, and behaviors about children's dental heath, school health educators should encourage students to have continuous dental care habits for lifelong dental health with repetitive education, rather than to deliver simple knowledge to students during dental health education.

Today, more chronically ill and handicapped children are being cared for at home by a family member caregiver. The task of caring for a family member may feel burden that the caregiver has less time and money and more work. Family functioning and their burden have influence on coping and adaptation of families with chronically-ill children. This study attempted to identify the levels of burden and family functioning in families of children with cerebral palsy and to examine their relationships. The instruments were burden scale developed by Suh and Oh(1993), and a modified Feetham Family Functioning Survey based on Roberts and Feetham.(1982). The subjects were 98 parents of children, under 15 years, who have cerebral palsy and being treated and living in Pusan. Data were collected through a self-administered question- aire from April 26 to May 29. The collected data were tested using frequencies, percentiles, means, t-test, ANOVA, and Pearson correlation coefficient with SPSSWIN program. The results of this study were as follows ; 1. The mean rating scores of burden and family functioning were 2.79±.51 and 4.12±.69, respectively. 2. The relationships between general character- istics and burden were statistically significant difference : degree of children's handicap(F=6.333, P<.01). The relationships between general characteristics and family functioning were statistically significant differences : familial relation with the children(F=3.628, P<.05), caregiver's health status(F=4.359, P<.05), age of children (F=4.185, P<.05), and duration of treatment (F=6.802, P<.01). 3. In families of children with cerebral palsy, there was significantly negative correlation between the burden of parents and the performance of family functioning(r=-.230, P<.05). There were significantly negative correlations between the burden of parents and the satisfaction of family functioning (r=-.211, P<.05), and between the perceived importance and the satisfaction of family functioning(r=-.481, P<.01); however, there was a positive correlation between the performance and the perceived importance of family functioning(r=.425, P<.01). In conclusion, this study suggests that families of children with cerebral palsy need family-focused nursing interventions as supportive care for relieving their burden and for improving family functioning.

The aim of this study was to investigate the relationships between bite force, masseter muscle and craniofacial morphology. 141 individuals were included. Bite forces were measured with a bite force transducer(SKT 2004). The facial morphology of the samples was evaluated on the Lateral and PA cephalometric radiographs(Asahi CX-90 SP). Ultrasonographic images were obtained for 36 individuals(Logiq 500). General status of the subjects were also measured for investigating possible relationships. Their relationships were analyzed by means of t-test, Pearson's correlation coefficients and simple regression analysis. In conclusion, bite force of molar was significantly correlated with craniofacial morphology for males and females, but not to masseter muscles. The masseter muscle for males had a significant correlation with craniofacial morphology. The unexpected negative correlations between size of masseter muscle and maxillary width was revealed for males. One possible way to arrive at a plausible explanation for the correlation between masster muscle, bite force and craniofacial morphology of males were the deep layer of masseter muscle had a great influence on males and the superficial layer of masseter muscle had a great influence on females.

To investigate the relationships among the traits related seed dormancy in rice, viviparous germination, dry-heat tolerance and seed longevity were tested using 164 M/G RILs ($F_{17}$) derived from the cross between Milyang 23 (Indica/Japonica) and Gihobyeo (Japonica). At 40 days after heading, the viviparous germination rates of Milyang 23 and Gihobyeo were 0.0 and 7.0%, respectively. The averaged viviparous germination rate of 164 MIG RILs was 3.2%, and their range was from 0.0 to 50.9%. In dry-heat treatment at $90^{\circ}C$ for 24 h followed by the pre-drying at $40^{\circ}C$ for 2 days, Milyang 23 showed higher germinability (98.6%,2.7 days to $T_{50}$) than Gihobyeo (37.6%, 12.9 days to $T_{50}$), and the mean germination rate of 164 M/G RILs was 72.4%. In 54 months after harvest, the germinability in Milyang 23 and Gihobyeo were 90% and 0%, and 71 lines among 164 M/G RILs showed the germinability over 90%. The relationship between seed longevity and dry-heat tolerance was linearly correlated with high positive correlation coefficient. The relationships between seed longevity and viviparous germination, and viviparous germination and dry-heat tolerance were linearly correlated with high negative correlation coefficient. Milyang 23 had higher tolerance against high dry-heat, viviparous germination and long-term storage than Gihobyeo, and 164 M/G RILs showed the medium values of parents.

Methods : The research was aimed at dental hygienists working at college dental hospitals, dental clinic of general hospitals, dental hospitals and dental clinics located in Seoul and Gyeonggi province where clinical practices were conducted for dental hygiene students. For analysis, collected data was analyzed by using SPSS 20.0. Results : Results derived from analysis on characteristic difference by pattern of hospital were observed that there was a significant difference in job satisfaction by pattern of hospital. Results from analysis on correlation among stress factors were observed that there was correlation between behavior and attitude, interpersonal relationships, role and activity, ideal and value, and treatment fields. Results derived from analysis on the effect of stress factors on the job satisfaction were observed that role and activity (p=.002<.01), ideal and value (p=.019<.05), and treatment fields (p=.032<.05) affected the job satisfaction, while behavior and attitude (p=.386>.05), and interpersonal relationships ((p=.421>.05) did not affect the job satisfaction. A stress factor, role and activity (${\beta}$=.350) affected the job satisfaction the most, followed by ideal and value (${\beta}$=.242), and treatment fields (${\beta}$=-.185). For the explanation ability, the stress factors accounted for 20.5% of the job satisfaction. Conclusions : In conclusion, most of the dental hygienists are satisfied with students' clinical practice by pattern of hospital. Positive correlation was shown between stress factors. Behavior and attitude and ideal and value are high in stress in college dental hospitals, role and activity and treatment fields are high in stress in dental hospital, and interpersonal relationships are high in stress in dental clinics.

This study is an attempt to investigate the chemical components of precipitation and its variation according to surface wind. Precipitation samples were collected by an wet-only precipitation sampler during the period of October 1994 to September 1995 at Kyungsan in Korea. The results obtained in t체s study are summerized as follows. The annual average of precipitation pH is 5.0, the highest month of pH is July of 5.5, and the lowest month of pH is December of 4.4. The most frequent appearance is in the range of pH 5.0 to 5.5 and its rate is 56.8%, The order of ion concentration In precipitation is SO42->NO3->Cl- in case of anion and $Ca^{2+}$>$NH_4^{+}$>$Na^+$>$Mg^{2+}$ in case of cation. It is found from our analysis that the correlation coefficient among the precipitation pH and ion components is below r=0.3, while the correlation coefficient between $SO_4^{2-}$ and NO_3^{-}$, $Na^+$ and $Cl^+$ is above r=0.8, respectively. The mean pH of precipitation is 4.8 under the westerly wind and 5.2 under the easterly wind. The concentrations of anion and cation under the westerly wind are more than the concentrations under the easterly wind. In autumn, the concentration of Na+ and $Cl^+$ under the easterly wind are higher than the concentration under the westerly wind. The correlation coefficients between wind speed and pH, ion components show very low correlation of -0.41 r 0.2. But the present study show that the correlation coefficient between wind speed and pH of precipitation is positive and the correlation coefficients between wind speed and ion concentration is negative.
