The prevalence of obesity is continuing to increase. Self-perceived body image among women has drawn a lot of attention in Korea due to unhealthy weight control trials. This study was conducted to determine the relationship between self-perceived body image and dietary intakes among Korean women. For the analysis, 1,747 subjects were selected after eliminating those who were likely to have recently altered their diet based on the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data. The subjects were divided into three groups: underweight, normal, and obese groups according to their perception of body image. Daily nutrient intakes, NAR (Nutrient Adequacy Ratio), and food intake frequency were assessed according to age group and body image perception. Only energy intake showed differences among the three body image perception groups across all age groups, but not statistical differences. Analysis of NAR and the order of most frequently consumed food items confirmed these findings. The ratio of underweight women that perceived their body size as normal or overweight was higher with younger age. Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. This study confirmed that nutritional knowledge is important for healthy weight control trials. Nutritional education for healthy dieting should be emphasized among Korean women.

This study was undertaken to develop and evaluate a nutrition education program with internet for students. A survey was conducted to find out needs for nutrition education program with 430 college or high school student in October, 1997. Eighty four point eight percent of female and 36.0% of male students had a plan to reduce their weight in a near future. Forty four point four percent of subjects obtained information about weight control from mass media, 28.6% of subjects obtained from their neighbor's recommendation. The information wanted to know were high-calorie foods, answered by 42.1% of females, and calorie expenditure of exercise, answered by 31.9% of males. The obese group showed higher preferrence to sweet foods, salty foods, hot foods, convenience foods, processed foods, animal foods, fried and oily foods, and eating-out than normal group(p<0.05). The obese group also showed a tendency of bad food habits, low intake of seaweeds, high intakes of animal fat, cholesterol-rich foods and salty foods. Amount of food intakes was inappropriate in obese group. An internet program for nutrition education was developed using the results of the survey and juvenile nutrition programs. The program consisted of 6 steps ; step 1 was to check one's physical status, step 2 was explanation about good food habits, step 3 was about food management, step 4 was methods of exercise for health, step 5 included how to maintain ideal weight, and step 6 was related-internet site. Pre-education test and post-education test was conducted to evaluate the nutrition education through internet. The score of nutrition knowledge increased from $74.2{\pm}7.4$ to $77.2{\pm}9.6.$ The score of food attitude did not change. The subjects wanted more information about nutrition from internet. Therefore, internet program of nutrition education with specific and interesting topics should be developed more.

We investigated perceptual similarity and the difference between client and vendor in information technology (IT) outsourcing projects. Specifically, we focused on each player's perception of how the fit of governance and peripheral knowledge affects the performance of IT project outsourcing. For 107 IT projects, we surveyed both client and vendor in the same IT projects and compared the responses of each side. Through a dyadic analysis, we first found that both client and vendor put more weight on the vendor's peripheral knowledge than that of the client as a positive influencer of project performance. However, regarding the governance style of an IT project, client and vendor showed completely different perspectives. The client believed that the vendor's peripheral knowledge positively contributes to the performance of IT project under the governance of outcome control. However, the vendor showed that its peripheral knowledge creates synergy effects under the governance of process control. Our interpretation of the perceptual similarity and difference between client and vendor delivers managerial implications for businesses that process IT projects.

The purpose of this study was to investigate nutrition knowledge, dietary attitude and a food habits of middle school students. The study was carried out through questionnaire. The subjects were 431 middle school students (boys 298, girls 133) in Chonbuk area. In nutrition knowledge, there were no significant differences in total scores between boys and girls. However, the girls showed higher score in knowledge of weight control than boys did (p<0.05). In dietary attitude, there were significant differences in attitude of 'balanced meal (p<0.05)', 'sufficient protein intake (p<0.01)', 'food diversity (p<0.001)' and 'overeating(p<0.00)' between boys and girls. The boys showed better dietary attitudes than the girls did. In food habits, there were significant differences in the rate of skipping breakfast (p<0.05), the rates of skipping dinner (p<0.001), the frequency of snacks (p<0.05), the type of snacks (p<0.05) between boys and girls. The girls showed higher rates of skipping a meal and frequency of snacks than the boys did. It suggests that gender should be considered for an effective and practical nutrition education for middle school students to improve dietary attitudes and food habits.

The purpose of this study was to develop a parenting intervention program and determine the efficacy of the program with low-birth weight infants and their mothers. Nine dyads for the experimental group and twelve dyads for the control group discharged from the Neonatal Intensive Care Unit of a University Hospital in Seoul were recruited for the study. For the intervention group, programmed education and support which focused on the maternal sensitivity of the infant's behavior. rearing environment. motherinfant interaction and infant care were given to each subject. Individual counseling and home visits were provided at discharge, one week after discharge. and one and three months of corrected age in every infant. Structured questionaires were administered and feeding interactions were videotaped and coded by a blinded certified observer. A Quasi-experimental design was conducted for this study. Postpartum depression, maternal self esteem. infant care burden, HOME. mother-infant interaction, and infant development were measured. Results were in favor of the intervention versus the control group. On the Beck depression inventory, intervention mothers showed decreasing trends in depressive symptom vs control mothers although, there were statistically no significant differences between the two groups at each time. The mean score of experimental group was 11.55(mild depression state) at discharge and became 8,6(normal state) at 1 month of corrected age. On the other hand, the mean score of the control group was 13.92(mild depression state) at discharge and became 14.0. Maternal self esteem in both groups improved over time. Infant care burden in both groups was also shown to increase over time. There was a significant difference between the two groups in HOME(p=.0340) at 3 months of corrected age. HOME scores of the experimental group and the control's were 31.10 and 25.58, respectively. Mothers' emotional and language responses were significantly high in the intervention group compared with the control group(p=.0155). Intervention group (53.33) showed a significantly high quality of motherinfant interaction compared with the in control group (42.80)(p =.0340). Intervention group mothers appeared have a better quality of mother-infant interaction behaviors. On the other hand, there was no statistical difference in the infant part between groups. Intervention group infants had higher trends in a general developmental quotient: although, there was no statistical difference between groups. The general developmental quotient of intervention infants was 102.56 and control's was 91.28. However, the developmental quotient of the domain of 'individuality-sociality' was higher in the intervention group infants compared with the control's(p=.0155). The concerns identified by parents revealed two domains of an infants' health management -knowledge and skills in caregiving of lowbirthweight-infants, characteristics of lowbirthweight infants, identifying a developmental milestone, coping with emergency situations and relaxation strategies of mothers from the infant care burden. Interview data with the mothers of low-birth weight infants can be used to develop intervention program contents. Limited intervention time and frequency due to time and cost limitations of this study should be modified. The intervention should be continuously implemented when low-birth weight infants become three years old. An NNNS demonstration appeared to be a very effective intervention for the mothers to improve the quality of mother-infant interactions. Therefore intervening in the mothers of low-birth weight infants as early after delivery as possible is desirable. This study has shown that home visit interventions are worthwhile for mothers only beyond the approach as an essential factor in ability of facilitating a growth fostering environment. In conclusion. the intervention program of this study was very effective in enhancing the parenting for the mothers of low-birth weight infants, resulting in health promotion of low-birth weight infants. The home-visit outreach intervention program of this study will contribute to the health delivery system in this country where there is a lack of continuous follow-up programs for low-birth weight infants after discharge from NICU, if it is activated as part of the home visit programs in community health systems.

In the early developmental stages of robotics,hydraulics played an important role. As the power-to-weight ratio of electric motors increased, they eventually replaced hydraulic actuators in robot manipulators. Recently, however, task requirements have dictated that the manipulator payload capacity increase to accomodate greater payload, greater length, greater reaction forces, and hydraulic actusators are being studied as an effective form of robot actuation again. For efficient control of hydraulic actuators, the knowledge of its dynamic equation is essential. However, the dynamic equation of hydraulic actuators are nonlinear, and the dynamic coefficients are time varying. In this paper, an estimation algorithm of the dynamic coefficients of the hydraulic piston dynamics are formulated. Simulation results are presented to show the possibility of the parameter estimation.

Objectives: This study examined the effects of nutrition counseling by the nutrition care process (NCP) on diet therapy practice and glycemic control in patients with type 2 diabetes mellitus. Methods: The survey was conducted on 49 patients whose hemoglobin A1c (HbA1c) level ranged from 6.5% to below 10% among patients aged 30~60s with type 2 diabetes mellitus. Nutrition counseling by the NCP process was carried out twice: first nutrition counseling and follow up counseling. The questionnaires were composed of 54 questions in five fields (general characteristics, health-related behaviors, diet therapy-related items, dietary life, diet therapy-related knowledge, diet therapy-related barriers). Nutrition intervention in nutrition counseling was performed based on the individualized diagnosis of NCP. Results: All the subjects practiced self-monitoring of their blood glucose levels, regular exercise, and diet therapy after NCP-based nutrition counseling. Diet therapy-related knowledge and practice by the subjects were improved after nutrition counseling. While the intake of boiled white rice decreased, the intake of boiled brown rice and barley rice in the subjects increased significantly. After nutrition counseling, the weight and HbA1c of the subjects decreased. Conclusions: These results suggest that personalized nutrition counseling by NCP process is effective for diet therapy compliance and glycemic control of type 2 diabetic patients.

'Goal Model' is core knowledge of 'Autonomic Control System' suggested to minimize human interference in system management. 'Autonomic Control System' performs 'Monitoring-Analysis-Plan-Execution', that is the four step of 'Autonomic Control', based on 'Goal Model'. Therefore, it is necessary to quantify achievement ratio of 'Goal Model' of target system. Thus, this paper present 'Probabilistic Evaluation of Goal Model' for methodology how to quantify achievement ratio of 'Goal Model'. It comprises 3-steps including 'Goal modeling and weighting', 'Goal model monitoring', 'Goal model evaluation and analysis'. Through these research, we provide core knowledge for 'Autonomic Control system' and it is possible to increase the reliability of system by evaluating 'Goal model' with applying weight. As case study, we apply 'Goal model' to a 'Smart IoT Kit' and we demonstrate the validity of the suggested research.

The purpose of this study was to obtain basic data of nutrition education for obese children and to examine food habits, food behaviors, and nutrition knowledge. A convenience sample of 84(male:62, female:22) obese children was selected from "98 Children Nutrition Camp". The survey design employed a structured questionnaire. The results of this study were summarized as follows. 1. The percentage of the subjects who overestimated their body weight was higher in female compared to male. Only 35.9% of highly-obese subjects considered them as 'very fat'. The experience of weight control was higher in female than in male, and it was also higher moderately- or highly-obese subjects compared to mildly obese. 2. 64.3% of subjects reported that they regularly eat breakfast. The percentage of the subjects who indicated that they eat at regular meal time or they eat very irregularly was highest in the highly-obese subjects. 3. 34.5% of subjects reported that they eat very fast. The eating speed was slower in female compared to male, and in obese subjects. 55.4% of subjects reported that didn't eating out. 4. 80.9% of subjects had snacks, and most of them had snack between lunch and dinner. The reason the subjects eat snack was hunger. The most favorite snack was cookies. 5. The most preferred and distasteful food was meats(32.1%) and vegetables(67.1%), respectively. 6. The score of food behaviors was relatively low in most subjects. 7. The level of nutrition knowledge was in order of fair(83.1%), poor(9.6%), excellent(7.3%), and was higher in male compared to female. Consequently the results of this study showed to disagreement among food habits, food behaviors and nutrition knowledge, and feel keenly the necessity of education connecting of these. This education had to be practical education to change food behaviors.

The purpose of this study was to examine the prevalence of nutrition label use and its association with demographic, weight control related factors, and diet among female adults in the Seoul area. Also, the study subjects' comprehension of nutrition labels was examined using objective measures. 279 females, between ages of 20 and 49, participated in this study. 66% of the participants reported to always or often use nutrition labels when purchasing foods. Nutrition label use was significantly higher among participants who were interested in losing weight and have more knowledge on nutrition, but significantly lower among subjects who were underweight (p < 0.05). Label users had higher fruit consumption and lower intake of fatty foods and snacks (p < 0.01). Only 20% of participants answered correctly regarding questions about the total amount of calories and fats contained in the entire food package tested, and only 15% answered correctly on questions about understanding of the % daily value. Comprehension of nutrition labels were significantly lower among participants who were less educated, underweight, and married (p < 0.05). In conclusion, our study suggests that proper use of nutrition labels may improve food choices and enable healthy dietary practices. Further efforts are needed to provide public a nutrition education program on how to read nutrition labels. Modifications of nutrition labels to make it easier to understand by the public should also be considered.
