This study was to investigate the trial status of weight control with internet. A survey was carried out by self-questionnaires with 500 female university students in Seoul. The average height, weight, and PIBW(Percentage of Ideal Body Weight) of subjects were 162.2$\pm$4.8cm, 51.9$\pm$6.1kg and 93.7$\pm$11.0%. It appeared that 50.6% of subjects were abnormal range of body weight : in particular 43.4% of the subjects were underweight. While 80.7% of subjects have deeply interested in weight control, 63.4% of them have attempted diet. It showed that 92.9% of subjects used internet, 54.3 % of them knew internet diet site, however only 39 of subjects used internet diet program. Most subjects used internet diet program in order to acquire diet information. According to PIBW, the overweight group is higher frequency of joining internet diet program than the others group. Therefore, education of weight control was needed with internet in abnormal weight group.

A hybrid supercapacitor is a promising energy storage device in view of its excellent capacitive performance. Commercial three-dimensional foam nickel (Ni) can be used as an ideal framework due to an interconnected network structure. However, its application as an electrode material for supercapacitors is limited due to its low specific capacity. Herein, we report a successful growth of MnO₂ on the surface of graphene by a one-step hydrothermal method; thus, forming a three-dimensional MnO₂-graphene-Ni hybrid foam. Our results show that the mixed structure of MnO₂ with nanoflowers and nanorods grown on the graphene/Ni foam as a hybrid electrode delivers the maximum specific capacitance of 193 F·g^-1 at a current density 0.1 A·g^-1. More importantly, the hybrid electrode retains 104% of its initial capacitance after 1,000 charge-discharge cycles at 1 A·g^-1; thus, showing the potential application as a stable supercapacitor electrode.

This study was to investigate of body perception, attitude on weight-control and self-esteem according to the weight group of high school students. Using the questionnaires taken by 777 first grade students in six high schools in Daegu, this study was conducted from August 20th to September 10th in 2007. Statistical data analysis were completed using the SPSS 12.0 program. The results of this study were as follows : First, girls are more interested in weight-control than boys, especially about obesity. As a result, they try to control their weight to lose weight in high school days with the right perception of weight. They also have good knowledge about weight-control and cut down the food intake. We need to study more about the reason why the self-esteem of girls' obesity group is high. Second, most of the boys controled weight for their health and they did exercise to lose weight and they are more satisfied with the result of weight-control and self-esteem than girls. About the body type, boys got affected by friends, and girls by TV. In boys' case, as the BMI is low and the difference between their present weight and ideal weight is small, they are more satisfied with the result of weight-control and prefer physical activities. In girls' case, as the BMI is low and their satisfaction with the weight-control result is high, they have good eating habit and high self-esteem. Third, compared with the weight group and their self-esteem, in boys' case, low-weight boys are high when they do physical activities more than 20 minutes, whereas when the normal-weights and over-weights are satisfied with their weight-control result, and the obese have good eating habit, it is high. In girls' case, the self-esteem is high when the normal-weights are satisfied with their weight-control result and over-weights prefer physical activities and the obese are interested in weight-control. Especially, the obese girls group show high self-esteem when they have interest in weight-control.

This study was intended to collect the baseline information on health status, nutrient intakes and dietary self-efficacy according to the obesity levels of male workers. Nutrient intakes of 224 male workers were assessed by 24 hr recall method; also, dietary attitude and dietary self-efficacy were investigated by self-administerd questionnaires. Biochemical characteristics such as blood pressure (SBP, DBP), total cholesterol(TC), hemoglobin (Hb), blood glucose (BG), SGOT, SGPT and ${\gamma}-GTP$ were assessed. Subjects were divided into normal, overweight and obese groups by body mass index (BMI). The health status was analyzed as normal group, health concerned group and disease suspected group. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio were high in the order of obese group, overweight group and normal group. Body fat mass was high also in the order of obese, overweight and normal group. Blood pressure (SBP, DBP) was the highest in obese group. SGOT, SGPT, ${\gamma}-GTP$ were higher in the obese group than normal and overweight groups. It was Proven that the percentage of those evaluated as low nutrient intakes were 71% for Ca, 50.9% for Zn, 70.5% for vitamin B2, 56.3% for vitamin C and 81.3% for folic acid. The dietary attitude scores were high according to the dietary self-efficacy. The age was positively correlated with dietary attitude, and the dietary attitude was positively correlated with dietary self-efficacy and total energy intakes. Dietary attitude showed the greatest total causal effect in relation to dietary self-efficacy. The results of this study showed some health problems and nutritional problems, indicating the need for nutritional management for male workers.

A majority of past studies have tried to investigate cigarette consumption in terms of smoker's cognitive aspects. However, smokers may experience feelings of guilt as a negative emotion while satisfying hedonic and social motive via cigarette consumption. Particularly, feelings of guilt associated with smoking may be induced when smokers' cigarette consumption contradicts their ideal self-concept or social self-concept. The research thus studied smoker's psychological mechanism, focusing on feelings of guilt associated with cigarette consumption. The results indicated that as smokers perceived physical harm associated with their cigarette consumption more than hedonic benefits from the cigarette consumption, they were more likely to experience feelings of guilt related to themselves and others. As smokers perceived social images of smoker as more negative, they were more likely to experience feelings of guilt related to others. Lastly, smokers' experiencing feelings of guilt related to themselves and others had a positive effect on smoking cessation intent. The research findings suggest that the anti-smoking campaign inducing guilt related to smokers' themselves (e.g., raising the price of cigarettes) and others (e.g., anti-smoking ads displaying physical damage of secondhand smoke on family members) can increase smokers' cessation intent.

This study was conducted to understand the relationships among adolescents' academic personality types (APT), learning behavioral types (LBT) and self-determinative learning motivations (SDLM). Regarding the measuring tools, the U&I APT test developed by Man-kwon KIM and Jong-cheol HAN (2002) and the learning motivation test translated by Kyeong-jin MIN (2006) were used. The study collected data from a total of 237 adolescents. First, gender did not influence the APT and LBT, and in terms of the introjected regulation as in the SDLM, female students were observed to have greater than the male students. Second, the normative type as in the APT was understood to have an identified regulation, an integrated regulation and an internal motivation as in the SDLM higher than those of the behavioral type or ideal type. Third, the normative type would be less rebellious and work harder to achieve a goal compared to the other types. Fourth, when adolescents have this motivation more voluntary and internal, they pursue greater goals for themselves, trying harder to fulfill their goals. The SDLM appeared to be related to most of the LBT.

This study examined the posttraumatic growth of North Korean defectors, the relation between their characteristics and posttraumatic growth and the factors influencing their posttraumatic growth, and explored methods of improving their mental health status. 145 North Korean defectors, who were trained in B city and G city, participated in the survey from February 1 to March 10, 2016. The posttraumatic growth, resilience, self-esteem, deliberate rumination, and impact of the (traumatic) event were measured using the PTGI (Posttraumatic Growth Inventory), RS (Rumination Scale, Resilience Scale), SES (Self-esteem Scale) and ISR (Impact of Event). The data were analyzed using the t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. The mean scores were 29.64 for posttraumatic growth. There were significant positive correlations between posttraumatic growth and resilience and between posttraumatic growth and rumination. The influence of the independent variables on the total posttraumatic growth was examined using regression analysis. Models including the variables (resilience, positive self-esteem, and rumination) explained 54.2% of the variance for the posttraumatic growth. These findings demonstrate that it is essential for nurses to continuously intervene and help North Korean defectors so as to promote their posttraumatic growth and resilience. Furthermore, it is also necessary for nurses to find ways to develop ideal interventions in order to activate deliberate rumination.

The poetic theme is a unified principle of which a poet writes poems out in his work. Theme is a poet's central thought expressed in his works. And it was described on the basis of writer's view of the world and life. In this study, I divided the themes of modern Sijo into three kinds according to the materials for a poem. Especially I am interested not so much in the poems taking outer problems of human life for the subject of a poem as in poems dealing with fundamental problems of human life such as self-consciousness, death, God's presence. Firstly, in modern Sijo which deals with poet's self-reflection and self-consciousness as a poet, poets examine himself. And he intends to write poems more severely. The more poet reflects self-consciousness, the more earnestly he tries hard to write good poems. As a poet. he feels complication between real-self and ideal self, so he tries to conquer the shame made in the gab of them. And he takes writing poems into his divinely appointed work in life. A kind of meta-Sijo is written in this circumstances. Secondly, there are modern Sijo, which shows deep concerns in death problems of human life. Thanatopsis expressed in modern Sijo is connected with poet's personal experiences. In most cases, poet describes fragmentary thoughts, sorrows and agony after death of his intimate persons. In Sijo, however, poets don't dig Into the death problem deep enough because of the characteristics of genre. But it is very significant work to take various materials of death into poetic themes in Sijo in that it makes us to reflect of human attitude of life. Thirdly, the poetic themes of dealing with fundamental problems of human and God are expressed in Sijo based on Christian view of the world. In such a poems, poet complains to God who looks in illogical human situations as a spectator of vulgar realities of life. But ultimately. poet expresses deep affirmation and obedience of God in his poems. So he manifests Christianity by the poetic paradox. Such poems change over the theme of modern Sijo the superficial Problems of reality to the deep situation of life.

Nutrition is important in the management of diabetes mellitus, however, there are few little education materials specifically designed for older adults. The objective of this study was to develop nutrition education materials for prevention and management of diabetes moll for older adults. Materials developed were a booklet and four leaflets. The contents of materials were based on lesson plans. After several revisions of the draft of materials, illustrations and icons appropriate to the contents were designed using illustrator 9.0 and Photoshop 6.0. The booklet was composed of five chapters and 40 pages. The first chapter began with an introduction about diabetes and diabetes management by diet, exercise and medication. The second chapter dealt with ideal body weight, calculation of adequate caloric intake and food exchange list. The third chapter provided information for meal planning and sample menus. The fourth chapter focused on practical tips on nutritional care of diabetes, by providing tips on reducing sugars, fat and salt, and suggestions on eating for special occasions. The fifth chapter dealt with information in case of low blood sugars, exercise and foot care. The topics of the four leaflets were “Diabetes, what is it and care”, “Food exchange list and meal planning”, “Healthy eating for diabetes”, “Special care for diabetes low blood sugars, exercise and foot care” Each leaflet was composed of six sections and was printed in large paper (B4 size) for older adults. The draft of educational materials were re-viewed by four nutrition professionals and finally pilot-tested with ten adults aged 50 and older. The characteristics of the developed materials are as follows, i) messages are delivered using simple, specific information, ⅱ) messages focused on practical applicable tips, ⅲ) various pictures, illustrations and artwork were created and inserted to enhance understanding and interest, ⅳ) sections including risk factor assessment, calculation of ideal body weight and meal planning were designed to induce the user's participation, ⅴ) sample menus and food pictures were inserted in the booklet, vi) characteristics of older adults and transformed characteristics are diversely used to help the user feel familiarity. These materials are self-explanatory and can be used by older adults. These materials also can be used widely in nutrition education at public health centers or senior centers.

This study aimed to find the differences in weight control status and eating behavior of satisfied and dissatisfied female high school students regarding their own body shape. The participants consisted of 238 students at two female high schools in Nonsan-si, Chungnam-do in May of 2008. Self-assessment evaluated present body shape and ideal body shape they would like to have by providing silhouette drawings. The subjects were divided into two groups, 'satisfied' and 'dissatisfied', according to the differences between present body shape and ideal body shape. In the distribution of subjects according to body mass index, 100% of overweight, 97.0% of normal weight and 48.7% of underweight belonged to the dissatisfied group. There were significant differences in weight control and eating behavior between dissatisfied and satisfied groups in terms of frequency and reasons of conducting weight control behavior, body weight return after weight reduction, skipping breakfast and consuming fast food. The satisfied group was two times more likely to not conduct weight control behaviors compared to the dissatisfied group. The main reason for trying to control weight differed according to the group; the reason was feeling fat in the dissatisfied group and desiring to be healthy in the satisfied group. The percentage of subjects that returned to their original weights after weight reduction was 5 times higher in the dissatisfied group. The percentages of subjects that regularly skip breakfast and consume fast food were both higher in the dissatisfied group than in the satisfied group. The dissatisfied group responded 'eating alone' more frequently among nine binge eating behaviors compared to the satisfied group. Both groups, however, did not show any difference in overeating of meals, eating speed, intake frequency of regular meals, food preference, preferred cooking method, carbonated beverage intake and snack eating behavior. In summary, the dissatisfied group tried more unnecessary body weight reduction and had poor eating behavior. Accordingly, to correct the biased perception of body shape by the majority of female high school students, the values of our society should change toward the pursuit of beauty of health.
