Purpose: The purpose of this study was to examine the relationships among perceived health, parental stress, social support, and quality of life of grandparent caregivers and to identify the factors influencing quality of their life. Methods: A descriptive correlational design was used. The data were collected by questionnaires from a convenience sample of 130 participants taking care of their grandchildren from ten children's daycare centers in Seoul, Korea from August to September, 2013. Data were analyzed using t-test, ANOVA, Pearson's correlation efficients, and multiple regressions. Results: Perceived health, parental stress and social support were correlated significantly with quality of life. As a result of the multiple regression analysis, education level, age of grandchildren, perceived health, parental stress and social support accounted for 48% of the variance in quality of life. Perceived health, parental stress, and social support were identified as factors influencing quality of life and the variable that most affected quality of life was perceived health. Conclusion: The results of the study indicate that health of people taking care of their grandchildren must be promoted while relieving their parental stress with appropriate social support in order to improve quality of life.

To investigate the effects of exercise-training on fat distribution several indicators of body fatness(percent body fat skinfolds thickness body circumference) were assessed in 128 healthy male subjects submitted to an 8-wk high intensive exercise-training. The subjects(average age=20.3$\pm$1.3 yrs) exercised 5 days/week. Daily energy intake and expenditure wee recorded. The results obtained are summarized as follows : 1) Through exercise-training lean body mass increased significantly (changes : 0.5$\pm$1.5kg; p=0.000) decreased significantly. 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$2.1mm and 0.4$\pm$1.8mm respectively. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) As a result of analyzing 12 of the fattest(top 10% of weight) and 12 of the leanest men(bot-tom 10% of weight) it indicated that there was a significant reduction of fat tissue in body composition and skinfolds thickness for the fat group. However there was no significant change for the lean groups. 4) Correlational analysis showed that predicting changes in body fat by infrared(NIR) measurement seemed to be closely associated with changes in body fat by Kim's equation and Katch's equation in young men.

Purpose: This study aimed to investigate problem behavior and its related factors in school-aged children. Methods: A descriptive correlational study was conducted with 221 mothers of children at 1st to 6th grades. Data were collected from March to April, 2015 using self-report structured questionnaires. Questionnaires included characteristics of subjects, Korean Child Behavior Checklist for measuring problem behavior and Children's Sleep Habits Questionnaire for assessing sleeping habits. Collected data were analyzed by independent t-test, $x^2$ test, and multiple logistic regression. Results: In logistic regression analysis, having any maternal job (aOR=2.8, 95% CI=1.1~6.9) and higher daytime sleepiness (aOR=2.9, 95% CI=1.2~7.4) were statistically significant contributors of internal problems. Higher bedtime resistance (aOR=2.2, 95% CI=1.0~4.9) and higher daytime sleepiness (aOR=2.8, 95% CI=1.2~6.3) were statistically significant contributors of external problems. Higher bedtime resistance (aOR=4.3, 95% CI=1.5~12.4) was statistically significant contributors of total problem behavior. Conclusion: School-aged children with sleeping problem are at risk for problem behavior. More attention is need to consider sleeping habits for supporting behavioral improvement in school-aged children.

The purpose of this study was to identify causal relationships among variables of transtheoretical model for exercise in the elderly A predictivel model explaining the stage of change was constructed based on a transtheoretical model. Empirical data for testing the hypothetical model was collected from 198 old adults over 60 years old in a community setting in Seoul, Korea in April and May,1999. Data were analyzed by descriptive statistics and correlational analysis using pc-SAS program. The Linear Structural Modeling (LISREL) 8.0 program was used to find the best fit model which predicts causal relationship of variables. The fit of the hypothetical model to the data was X2=132.85. (df=22, p=.000). GFI=.88, NNFI=.35, NFI=.77, AGFI=.59 which was not favorable but the fit of modified model to the data was X2=46.90. (df=27, p=.01).GFI= .95, NNFI=.91, NFI=.92, AGFI=.87) which was more than moderate. The predictable variables of stage of change for exercise of the Korean elderly were helping relationship, self cognitive determination, conversion of negative condition in process of change and efficacy for exercise. These variables explained 68% of stage of change for exercise of the Korean elderly.

Purpose: This study was conducted to investigate the degree of dry mouth and oral health-related quality of life and to identify factors contributing to oral health-related quality of life for community-dwelling elders. Methods: A descriptive correlational study design was used. Participants were 156 older adults from two senior welfare centers. Data were collected on February 21, 22 and 29, 30, 2009 using structured questionnaires. Enter type multiple regression analysis was used to identify factors influencing oral health-related quality of life according to general and oral health characteristics. Results: There were significant differences in oral health-related quality of life according to living arrangement, insurance, smoking, number of natural teeth, and denture type. The oral health-related quality of life had significant correlations with the number of chronic disease, number of medications, and dry mouth. Factors influencing oral health-related quality of life for community-dwelling older adults were dry mouth, number of chronic disease, and medical aid, which explained about 47.9% of total variance. Conclusion: These results indicate that in order to promote oral health-related quality of life for older adults, prevention or management of chronic diseases as well as oral health and dry mouth are needed for this population, and especially economically poor elders.

Objectives: The study was conducted to investigate the relationship between several stress measures in everyday life, emotional eating behavior, and dietary pattern (snacks, fatty foods, sweet beverages, fruits and vegetables) in school-aged children. Methods: One hundred and ninety-four students of an elementary school located in Seongnam City participated in the study. The students responded to the survey questionnaire by self-report, which consisted of items regarding general characteristics, height, weight, dietary habits, frequency of consuming healthy (fruits and vegetables) and unhealthy foods (snacks, fatty foods, and sweet beverages), emotional eating behavior, and daily stress. Correlational analysis was performed to examine the relationship between stress, emotional eating behavior, and dietary pattern, and Poisson and logistic regression analyses were conducted to investigate the effects of stress on dietary pattern. Results: Positive correlations were found between all stress factors and emotional eating behavior and between the friend and personal factor (one of the stress factors) and the consumption of sweet beverages. The frequency of consuming sweet beverages was 2.6 times higher in the high stress group than in the low stress group (95% CI). Conclusions: Children's daily stress was associated with emotional eating behavior and undesirable dietary pattern such as consumption of sweet beverages.

Purpose: The purpose of this study was to examine the psychometric properties of the Korean version of the General Practitioner Assessment of Cognition (K-GPCog) scale. Method: The K-GPCog consists of the 2 subscales, patients and caregivers. Using a sample of 412 community-based Korean older adults, internal consistency reliability was estimated using Cronbach's alpha. To evaluate validity of the K-GPCog, correlational analysis was conducted using Pearson r between K-GPCog and the Korean Dementia Screening Questionnaire (KDSQ). Results: Cronbach's alpha coefficients of the K-GPCog patients' and caregivers' subscales .788 and .794 respectively. Pearson's correlation coefficients were r=-.374, r=-.481, and r=-.493, respectively for the subscales of patients and primary caregivers, and total K-GPCog. The degree of diagnostic agreement about the risk for cognitive disorders of older adults showed 11.7% and 11.2% respectively for the K-GPCog and the KDSQ. Conclusion: The findings provided preliminary evidence of the K-GPCog as a useful screening measure for detecting mild cognitive disorders of Korean older adults. The K-GPCog is particularly useful to identify cognitive disorders from primary caregivers when it is difficult to assess the level of cognition of older adults.

Purpose: The purpose of this study was to identify the relationship between fatigue and nutritional status in gastric cancer Design. A correlational and crossectional study design was used. Method: Fatigue was measured using the Revised Piper Fatigue Scale. The parameters for nutritional status consisted of BMI, Hb, Hct, total protein, albumin and lymphocyte count. Result: The mean score of fatigue was $94.31{\pm}22.08(mean\;average\;4.48{\pm}1.00)$. The subdimensional scores of fatigue revealed $34.15{\pm}8.76$ for behavior/severity, $22.00{\pm}7.93$ for cognitive/mood, $21.67{\pm}5.56$ for sensory, and $20.81{\pm}6.69$ for affective. And the level of BMI, Hb, & Hct were under the normal ranges. In the ancillary analysis, there was a significant difference on the fatigue scores by the groups of present diet(F=3.343, P=.026). Age, types of treatments, period after diagnosis and weight change were related to nutritional status. There was a significant negative correlation between fatigue and nutritional status(r=-.371, P=.004). Conclusion: Considering the relationship between fatigue and nutritional status, nurses can identify the risk group most vulnerable to fatigue and malnourishment in order to provide appropriate interventions for them.
