Objectives: People often fail to maintain their weight even though they have succeeded in weight loss. The purpose of this study was to review previously published study results with regards to the predictive factors associated with weight loss maintenance after successful weight loss. Methods: The authors searched for the articles related to weight loss maintenance after successful weight loss, published up until June 2019 on PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, Research Information Sharing Service (RISS), and Koreanstudies Information Service System (KISS). A total of 76 articles were finally selected. From the study results, changeable and unchangeable predictors were extracted, and these predictors were examined according to detailed categories. Results: The changeable predictors of weight loss maintenance included behavioral factors, psychological factors and treatment process-related factors, whereas the unchangeable predictors included genetic and physiological factors, demographic factors, history of treatment on obesity-related factors. The main factors of weight loss maintenance were changeable predictors such as healthy eating habits, dietary intake control, binge eating control, regular exercise and physical activity, depression and stress control, social supports, self-regulation, self-weighing and initial weight loss and unchangeable predictors such as low initial weight and maximum lifetime weight. Conclusions: The results of our review results suggest that changeable and unchangeable predictors of weight loss maintenance should be carefully examined during treatments of obesity.

It is essential to improve the quality of life of the elderly in aging society. Regular exercise as nursing intervention is needed to prevent diseases, maintain and promote their health, and thus promote the quality of life for the elderly, especially who generally had poor cognition for their health maintenance and promotion in a low class community. Subjects consisted of 30 women. over 65 years old in a community welfare center, who lived in the low class apartments financially supported by the local government in G city, Gangwon Province, Korea. The program consisted of dancing on music for approximately 50 minutes, 3 times a week for 10 weeks. Experimental data were analyzed with $x^2-test$, t-test, mean values, standard deviation, percentage of change and paired t-test using SAS program. After the recreation dance, the mean value of the experimental group was decreased from 7.62 to 7.44 (t=-0.258, P=0.799), and that of the control group was also decreased from 7.00 to 6.58 (t=-0.971, P=0.349) in depression. However, there were no statistically significant differences in scores of depression between two groups. In life satisfaction, the mean value of the experimental group was increased from 19.07 to 26.50 (t=2.392, P=0.030), but that of the control group was decreased from 15.92 to 13.71 (t=-1.060, P=0.305). Thus it shows that there was a statistically significant improvement on life satisfaction after the recreation dance.

This paper presents a Web-based interactive and adaptive learning system that helps students learn the pumping lemma for the family of regular languages. Our system allows the students to proceed with their learning according to their individual differences through Web-Based Instruction and gives them opportunities for the interaction so that they can practice exercise related to the learning and gain feedbacks on the results of the exercises immediately. Especially, the system provides adaptive scaffolding that helps learners understand each step for the proof of the pumping lemma. Unlike existing systems that support learning the pumping lemma, the proposed system defines possible errors in advance and provides appropriate messages for corresponding errors. In addition, the system allows the learners to decompose a string into three parts so that they can understand the pumping lemma precisely.

Carotenoid-rich foods focus one's attention on the prevention age-related diseases. This study was conducted to investigate the carotenoid status and look into the factors that affect the bioavailability of carotenoid in 121 elderly nonsmoking Korean women. Carotenoids and lipids in plasma, and nutrient intakes including carotenoid were studied. The mean plasma total-cholesterol, HDL-cholesterol, LDL-cholesterol and triacylglycerol concentrations were 220.0 mg/dl 49.5mg/dl , 139.2mg/dl and 157.4mg/dl , respectively. Significantly positive correlations were found between the plasma lutein + zeaxanthin, lycopene and $\beta$-carotene concentrations and the intake of fruits (r=0.17, r=0.20, r=0.19). However, significantly negative correlations were found between the plasma zeaxanthin, and $\beta$-carotene concentrations that adjusted for carotenoid intakes and intakes of vegetables (r=-0.21, r=-0.19), and between plasma lutein＋zeaxanthin, lycopene and $\beta$-carotene concentrations that adjusted for carotenoid intakes and intakes of fruits (r= -0.21, r=-0.18, r=-0.24). After the adjustment for plasma lipids, there was no correlation between the plasma carotenoid concentrations and the carotenoid-rich foods. However, after adjustment for fiber intake, significantly strong positive correlations were found between the plasma carotenoid concentrations and carotenoid-rich foods. The plasma levels of carotenoid biomarkers (plasma carotenoid concentrations adjusted for dietary fiber intakes) decreased with age, and the plasma levels of lycopene biomarkers (plasma lycopene concentrations adjusted for dietary fiber intakes) increased with regular exercise. However alcohol drinking had no impact. These results suggested that age, physical activity, and dietary fiber intake affected the bioavailability of carotenoid. Therefore, when the elderly have carotenoid-rich foods, they should consider ways of increasing the bioavailability of carotenoid through cooking methods and Physical activity.

The present study was conducted to investigate the effect of nutrition education program on nutrition knowledge, eating behaviors, food habit, nutrient intakes in obese children and their parents who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130% and 36 of their parents. The nutrition education for the subjects was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40 min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2 weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6 times. The nutrition knowledge, eating behaviors and food habits were surveyed by using questionnaires before and after the education. The nutrition intakes of the children were surveyed before and after the education by 3-day food record method. The nutrition intakes of the parents were surveyed before and after the education by using semi-quantity questionnaires. After the education, the mean nutrition knowledge scores were significantly improved compared with the pretest scores in both children and parents. After the education, all subjects' eating behaviors were significantly changed positively and calorie and carbohydrates intakes were significantly decreased and vit. C was significantly increased in obese children. The food habits of the parents were significantly improved after the education. These findings show that the well-designed nutrition education program for obese children and their parents can be an effective approach to help them to improve their nutrition knowledge and to establish desirable food habits and eating behaviors.

Purpose: The aim of this study was to investigate coping styles for dysmenorrhea and explore factors related with their coping styles according to different health loci of control in middle schoolers. Methods: Data were collected by using a structured questionnaire for 572 students from three middle schools in Seoul from March 22 to April 2, 2010. The measurement included menstrual distress, coping method questionnaire and health locus of control. The data were analyzed by using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis. Results: Middle school students used the active behavioral coping style more often than the avoidance style. There was a significant difference in means within each coping style including levels of stress, levels of health, and regular exercise. There were also significant correlations between each coping style and health locus of control. Regression analyses indicated that the health locus of control factor is the most powerful factor in each coping style. Conclusion: We observed that various coping methods are used for dysmenorrhea in middle school students. However, the active behavioral coping style is dominant in such a condition. Based on these results, we need to develop a health locus of control to improve coping styles for dysmenorrhea.

Purpose: This study was conducted to confirm the factors affecting recipients' quality of life by two types of hypertension management, one was telemedicine provided by community health posts(CHPs) in a rural area, the other was traditional hypertension management by comparing patients' health related lifestyles, self-efficacy and health related quality of life. Methods: The study was conducted from February 1, 2015 through April 25, 2015 on 193 hypertension patients in 6 CHPs consisting of 98 patients in 2 CHPs running telemedicine and 95 patients in 4 CHPs running traditional hypertension management services. The data were analyzed and assessed with frequency, percentage, chi-square test and multiple regression. Results: Self-efficacy and health related quality of life were high for the subjects managed by traditional hypertension management services. Self-efficacy, age, hobby, balanced meals, more than 7~8 hours sleep and regular exercise, which affected the quality of life for recipients were explanatory in 45.9%(F=22.368, p<.001). Conclusion: When any services utilizing telemedicine are provided in the future, consideration of emotional aspects including self-efficacy and quality of life is recommended.

Purpose: The purpose of this study was to investigate the relationships among psycho-social well-being, and health perception and behavior in clinical nurses. Methods: The data were collected from 362 nurses employed at five general hospitals. A self-reported questionnaire was used to assess demographics and job characteristics, health perception and behavior, depression, and psycho-social stress. The data were analysed using Cronbach's alpha, descriptive statistics, t-test, and ANOVA. Results: While nurses perceived themselves to be in good health, represented by a high mean for health perceptions, actual health behavior was poor as the mean for health behavior was low. Forty two percents of the subjects were categorized as having major depression and high-stress levels. There were statistically significant differences in psycho-social well-being according to age, marital status, years of employment, and monthly salary. Also, there were significant differences in psycho-social well-being according to health perception, regular meals and exercise, sufficient sleep, job related injury and accident, and absences for ill. Conclusion: In order to prevent depression and improve psycho-social well-being among clinical nurses, organizational support and health management needs to be focused on high-risk nurses. Furthermore, it is essential to consider the health perception and behavior of clinical nurses.

This study analyzes the effects of caring for grandchildren on Korean grandparents' health, using the Korean Longitudinal Study of Aging from 2006 to 2012. We investigate how caregiving is provided and analyze the effects of caregiving on grandparents' physical health, mental health, and health-related behaviors. As elderly people's health is generally frail, it is unclear whether the provision of childcare affects their health negatively. We control for the endogeneity of caregiving by an individual fixed effect (FE) model and instrumental variable-fixed effect (FE-IV) models. Using these models, we determine the endogeneity of caregiving and show that the significant effects of caregiving on health disappear as we control for endogeneity in the FE and FE-IV models. Even after controlling for endogeneity, we find that caregiving increases the probability of feeling pain as well as the number of different types of pain. Furthermore, caregiving increases the probability of restrictions on daily activities because of pain. On the other hand, caregiving reduces the symptoms of depression. In relation to health-related behaviors, caregiving reduces the probability of physical exercise and regular meals. Our results imply that although caregiving has a positive effect on mental health, the increase in physical pain and in non-healthy behaviors may lead to a deterioration of the caregiver's long-term health, which in turn may increase the medical costs of the elderly. Potential policy alternatives are discussed in the paper.
