This study investigated first, socio-economic, residential characteristics, and values for future life among low-income family wives. Second, the relationship of these characteristics to the wives' stress was examined. The subjects were 249 mothers of urban low-income families whose children attended one of 20 daycare centers located in poor residential areas. The instruments included Social Network Scale, Home Stress Scale, and Occupation Stress Scale. Data were analyzed by means, standard deviations, frequencies, paired t-tests, and the stepwise multiple regressions. We found that a majority of the mothers and their husbands had high school educational status and simple labor or sales/service work status. They lived in rental houses or apartments. Their families of origin were a major source of emotional supports. Insufficient income for non-employed wives, long work hours and lack of free time for employed wives were a major stress. Levels of the wives' home-related job-related stress were negatively related to their own and their hudsbands' work status.

The purpose of this study is to examine the relationships between quality of life and demographic characteristics and health-related behavioral characteristics, and their relevance to variables that represent health conditions among metropolitan-dwelling older adults. The study subjects were 380 senior citizens aged 65 or older living in the D metropolitan area, and data collection was conducted by visiting them for interviews in June 2019. A binomial logistic regression analysis was performed to examine the relationship between independent variables (demographic characteristics, health-related behavioral characteristics, health condition variables) and the dependent variable (quality of life) while controlling for gender and age. As a result, the factors related to quality of life for those surveyed were education level, spousal status, living status, bear for living expenses, average monthly allowance, satisfaction with daily life, evaluation of sleep quality, smoking and eating habits, amount of regular exercise, hobbies, subjective health status, physical disability (if any), hearing ability, visual acuity, mastication ability, urinary incontinence (present or not), and amnesia. The above results suggest that quality of life for the elderly living in urban areas is significantly related to variables that indicate demographic characteristics, health-related behavioral characteristics, and health condition.

This study was aimed to assess the degree of addiction on computer games and find factors related to game addiction, health perception and health promoting behavior in elementary school students. A study subjects were 814 students in 5th and 6th grades at 4 elementary schools in a city and a county. The items in questionnaire was consisted of general characteristics, circumstances and habits related to utilization of computer and internet game playing, and degree of addiction, health perception and health promoting behavior. We analyzed data using chi-square test, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, addictiveness on internet game was significantly related to type of computer utilization, frequency and duration of internet game playing, gender, after-school activities, grade points, economical status, and location of computer in a house. Health perception was significantly related to addiction points, gender, residential area, and grade points. And health promoting behavior was significantly related to addiction points, grade level, grade points, and health perception points. Since health promoting behaviors of children in elementary school are in the way of making, their degree of addiction to computer games can greatly influence their attitude towards health and their future life pattern as adults. Therefore an educational prevention program including counselling on game addiction should be devised. And researches will be needed for developing the Korean standard for measuring degree of addiction and a prevention program for peer group's game addiction.

In this paper, a new PD measurement technique of pulse superposition method was proposed in order to investigate both PD mechanism and phase related PD patterns. From the experimental results, we could find that the polarity and the phase angle of the superposed pulse take great effects on PD characteristics and these method make it possible to get the physical information which statistical approach can not give. We could conclude that the changes of PD characteristics in the void surrounded by polymers may be attributed to the injection of charge carriers thereby formation of space charge in the surface and/or the bulk of the polymer.

The purpose of this study was to identify the effect of individual emotional characteristics (empathetic concern and emotional contagion) on emotional labor (frequency of emotional display, intensity and variety of emotional display, surface acting, and deep acting) of school dietitians. Data was collected through a questionnaire survey of 309 school dietitians and then analyzed statistically by SPSS 18.0 package program. The results of this study were as follows: empathetic concern (3.93) occurred more often than emotional contagion (3.22) in school dietitians. The older (p < 0.001) and more experienced (p < 0.01) they were, the higher empathetic concern they had. It showed that married dieticians (p < 0.001), nutrition teachers (p < 0.01), and dieticians who were working in elementary schools (p < 0.01) had a higher rate of empathetic concern than single dieticians, non-nutrition teachers, and dieticians who were working in middle and high schools, respectively. Their level of emotional labor was the highest in deep acting (3.32), followed by surface acting (3.28), frequency (3.12), intensity and variety (3.09). According to multiple regression analysis, emotional contagion proved to be strongly significant and positively related to frequency of emotional display (${\beta}=0.257$, p < 0.001). Both empathetic concern (${\beta}=0.117$, p < 0.05) and emotional contagion (${\beta}=0.162$, p < 0.01) were positively related to intensity and variety of emotional display, and empathetic concern (${\beta}=0.173$, p < 0.01) had also an effect on deep acting. These results suggested that the emotional labor of school dietitians should be managed on the organizational viewpoint, not a personal matter.

BACKGROUND/OBJECTIVES: There are limited studies investigating the eating patterns of children's favorite foods. The present study aimed to evaluate a wide range of children's favorite foods, derive its eating patterns, and identify factors related to the patterns. SUBJECTS/METHODS: A nationwide cross-sectional study included 5,458 students in elementary, middle, and high schools. The survey was conducted at each school to evaluate children's favorite food intake, including the intake frequency of 31 food items or food groups, and its related factors, such as demographic, economic, and environmental characteristics and awareness of policies on children's favorite foods. Factor analysis using varimax rotation method and logistic regression analysis were conducted. RESULTS: Two factors were derived as major eating patterns from data of children's favorite foods: the 'unhealthy eating pattern' which mainly involves confectionery, chocolate, ramen, fried food, etc.; and the 'healthy eating pattern' which mainly involves soybean milk, vegetables, fruit juice, and nuts. A stepwise selection procedure through the regression analysis revealed that allowance, use of screen media, less awareness of policies on children's favorite foods, and less interest in health were positively related to the tendency of unhealthy or less-healthy eating patterns (P < 0.05). CONCLUSIONS: This study examined that the eating patterns of children's favorite foods were associated with certain environmental characteristics and awareness about the related policies. These findings suggest that a nutrition education program regarding children's favorite foods needs to be conducted according to the characteristics of students to develop their healthy eating habits and proper choice of favorite foods.

This study examined elementary school students' perceptions and acceptances related to kimchi in Jecheon area. This study examined with 388 elementary school students. Demographic characteristics of subjects, perceptions and acceptances related to kimchi were surveyed by self-developed questionnaires. Exactly 54.1% of subjects ate kimchi more than once per day, whereas 2.8% of subjects never ate kimchi. With regard to location, the home showed the highest percentage. Exactly 94.3% of respondents answered that eating kimchi was good for health. For acceptance, 86.9% of respondents answered that they liked kimchi. Reasons for liking kimchi were texture and special taste in order, whereas the most common reason for disliking was spicy taste. Baechu-kimchi (Chinese cabbage kimchi) was highly preferred, whereas pa-kimchi (green onion kimchi) was not. Subjects with an extended family preferred oisobagi (cucumber kimchi). There were significant differences between the groups with balanced dietary habits and unbalanced dietary habits in terms of acceptance for chonggak-kimchi (small radish kimchi), yeolmu-kimchi, kkadugi, mulkimchi (watery kimchi) and oisobagi. Elementary school students in Jecheon area recognized the importance and necessity of kimchi in Korean meals. Exactly 23.7% answered spicy taste as the reason for liking reason while 37.3% answered spicy taste as the reason for disliking. These results suggest that various kinds of kimchi need to be developed for elementary students with different levels of spiciness in addition to continuous nutrition education about balanced dietary behaviors at school and home.
