Purpose : To identify general characteristics of school personnel with recent fatigue which was the most frequent symptom among subjective symptoms and to explore fatigue-related factors by evaluating physical and perceived health status, life style, and symptoms through data mining techniques. Methods : We collected a data of the 1,147(male 545, female 602) who were elementary, middle, or high school personnel, answered a questionnaire, and received physical examination in Seoul School Health Center from September to November in 2000. And we investigated the differences between fatigue group and non-fatigue group for demographic characteristics, physical health status, perceived health status, symptoms, and laboratory values by frequency, chi-square test, t-test, or simple logistic regression analysis by SAS package 8.1, and then selected significant variables as input variables of a decision tree analysis of CART model by SAS E-miner. Results : In general characteristics, the fatigue consisted of 41.1%(male 35.2%, female 46.4%) among 1,147 school personnel. In classical statistics, factors related with fatigue were female, lower means of systolic and diastolic pressure, young age, personnel in middle school, irregular eating habit, no exercise a week or less than 30minutes exercise a day, perception of unhealthy status, and subjective symptoms including short of breath at exercise. In simple logistic regression to examine the relationship between selected independent variables and fatigue as a dependent variable, the odds ratio of gender (female vs male) was 1.58 times, and young age ( 20s vs 60s) 20.67 times, and middle vs high school personnel 1.86 times. However, we mined combined several characteristics by SAS-E miner. In CART model, if health perception was healthy, and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%. Conclusions : The fatigue consisted of 41.1%(male 35.2%, female 46.4%). In classical statistics, fatigue-related factors among school personnel were young age, female gender, perceived unhealthy status, subjective physical symptoms, poor life-style, and lower blood pressure rather than only physical health status. However, in data mining, if health perception was healthy and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%.

This study is a descriptive survey study to investigate the quality of sleep and to compare the factors relating quality of sleep in the young-old people and the old-old people. The subjects of the study were 200 elderly people who live in the G-region applying convenient expression method. Using a structured questionnaire, sociodemographic characteristics, lifestyle and health-related characteristics, depression, and quality of sleep were examined. We analyzed ${\chi}^2-test$, t-test, ANOVA(scheffe's test), Pearson's correlation coefficient and multiple regression using IBM SPSS WIN/21.0. The results of the study were as follows. The quality of sleep was significantly worse in the old-old people than in the young-old people. In young-old people, only depression (r=-.22, p=.038) showed a significant negative correlation with sleep quality. Old-old people was a significant negative correlation between sleep quality and depression (r=-.19, p=.045) and subjective health status (r=-.29, p=.002). In the young-old people, job, chronic illness, and economic level were significant influencing factors in the quality of sleep. In the old-old people, chronic disease, subjective health status, and smoking were significant influencing factors. The results of this study can be used as basic data for establishing tailored strategy for ages that can improve health of the elderly.

Methods. 590 elderly in 6 rural communities of Jeju Province were interviewed, using a questionnaire consisting of sociodemographic characteristics, health behavior, quality of life, and MMSE-K Results. Prevalence of cognitive impairment was 33.1 % (39.1 % of females, 16.76% of males). Prevalence of dementia was 12.4% (16.3% of females, 2.87% of males). Factors related to cognitive impairment were age, sex, education, standard of living, employment status, and subjective health state. Conclusions. In community health care for the elderly, factors relating to cognitive impairment have to be considered. When planning community health care, priority should be given to the elderly; who need care but live alone; who lack social support; who have a low standard of living; who experience discomfort in the activities of daily living; who believe they are not in a good state of health; or whose life satisfaction is low.

This study aims to explore the Internet personal broadcasting quality factors that influence viewer satisfaction and dissatisfaction based on the motivation-hygiene theory. Specifically, the quality factors that affect viewer satisfaction of Internet personal broadcasting are derived from the perspectives of extrinsic (contents usefulness and media usability), intrinsic (emotional/cognitive/behavioral enjoyment and creator characteristics), and social motivation (visibility, subjective norm, image, sociality). The data of 200 respondents was used to analyze the relative impact of satisfaction and dissatisfaction with the Kano model, which assumes that viewer satisfaction at both functional and emotional levels varies over quality attributes. In the empirical analysis, the quality factors were classified into attractive, one-dimensional, must-be, and indifferent quality. In addition, it was found that the customer satisfaction coefficient was high in the order of uniqueness, differentiation, and visibility. On the other hand, as a result of applying the dissatisfaction coefficient, it was identified in the order of donation, content reliability, and creator responsiveness.

This study analyzed consumer attitude, habit strength, subjective norm, a pros evaluation, and intention to consume to estimate perceptible variables that affect apple consumption. Data were collected from 207 men and women through a selfadministrated questionnaire. A partial least squares regression was conducted as one of structural equation models to estimate and test hypotheses. The results showed that attitude, habit strength, and the pros evaluation affected the intention to consume apples, and that the intention increased apple consumption. The results also showed that some marketing strategies are needed to promote apple consumption and to make consumers change their intention, to develop habits for eating apples by changing their diets, and to impress upon them that apples are good for health. This can be interpreted as meaning that it is most important to understand consumer behavior, particularly consumer psychology, which is reflected in the recent trend of marketing that concentrates on meeting the consumer's needs rather than the producer's.
