In the Health Promotion Law proclaimed on January 1995, nutritional improvement at national level was emphasized and designated as one of the jobs to be carried out by local governmnets. With such a situational necessity, we conducted a dietary survey along with an anthropometric measurement, biochemical assessment and questionnaire analysis on general characteristics of the students from 3 junior higher schools in Seoul area. About 300 students had participated in the study and the data from only 139 students, 28 boys and 111 girls, with complete report of dietary intake were subjected to analysis, comparison and discussion. Fasting blood samples were drawn and analyzed for hemoglobin, hematocrit and total cholesterol. Dietary intake was monitored by 1-day 24hr recall +2-day food record. In general, the average intake of nutrients for most of the subjects were above RDA for korean of that age except for 2 nutrients namely, vitamin A and calcium, of which average intake corresponded to 46-69% of RDA. In addition to this kind of nutritional imbalance, there were several other factors of nutritional problems such as skipping breakfast, overeating at dinner and frequent eating of snacks. As the best countermeasure for these kinds of nutritional problems, more detailed campaign and prractical nutrition education for these adolescents are necessary. Only through proper education and guidance for them, the healthy and intellectual man power could be guaranteed for the forthcoming 21st century.

Purpose: This study was to compare changes in health behaviors, motivational factors, cardiovascular risk factors, and functional status (SIP) after implementing the 6-month motivation-enhancing program to institutionalized elderly women. Methods: Sixty-four elderly women participated. Face to face interviews with blood sampling and anthropometric assessment were conducted at the pretest, 10 weeks and 6 months during the program. Results: 1. The program participants showed significantly better health behaviors over 6 months. The mean motivational level was also significantly improved, especially for perceived benefits, perceived barriers, and emotional salience. 2. The mean of cardiovascular risk factors for the participants was 21.8 at the level of low to moderate risk. After completing the program, total risk score was significantly decreased to 18.7 at 10 weeks, and further to 17.7 at 6 months. A significant reduction was also found in HDL and LDL-cholesterol levels, blood pressure, obesity, inactivity, and stress. 3. The functional status (SIP) was 11% at the baseline and significantly changed in positive direction at 10 weeks(M=9.3) and at 6 month(M=6.3). The significant improvement was also found in physical and psychosocial dimensions and sleep/rest dimension. Conclusion: The motivation enhancing program was effective to reduce cardiovascular risks and to improve the functional status of institutionalized elderly women by motivating them to perform better health behaviors.

This paper presents a CAD program develpoed on a microcomputer in order to support graphic and computational assessment of ergonomic problems associated with the design of a man-in-cab system. The program is coded to help workspace designers with ergonomic evaluations needed in the design stage. This paper proposed a biomechanical -ergonomic evaluations needed using man and workplace models. The human model is developed to have dimensions obtained from the Korean anthropometric data reported in 1992. Its graphical representation is based on a wire-frame model but, whenever necessary, body segments can be represented by a solid model with hidden line/faces removed and shaded. Workplace models are presented for cabs of the excavator, one of the most popular construction vehicles. A workplace model consists of an operator seat, a steering wheel. two control levers, two pedals, and a control panel. The workplace elements can be modified in their sizes, positions, and orientations by changing the reference point and design parameters. An algorithm for the view test is suggested and loaded to provide a visual evaluaiton of the overall layout of a workplace model.

Background: Infants with deformational plagiocephaly (DP) usually present with cranial vault deformities as well as facial asymmetry. The purpose of this study was to use three-dimensional anthropometric data to evaluate the influence of cranial deformities on facial asymmetry. Methods: We analyzed three-dimensional computed tomography data for infants with DP (n=48) and without DP (n=30, control). Using 16 landmarks and 3 reference planes, 22 distance parameters and 2 angular parameters were compared. This cephalometric assessment focused on asymmetry of the orbits, nose, ears, maxilla, and mandible. We then assessed the correlation between 23 of the measurements and cranial vault asymmetry (CVA) for statistical significance using relative differences and correlation analysis. Results: With the exception of few orbital asymmetry variables, most measurements indicated that the facial asymmetry was greater in infants with DP. Mandibular and nasal asymmetry was correlated highly with severity of CVA. Shortening of the ipsilateral mandibular body was particularly significant. There was no significant deformity in the maxilla or ear. Conclusion: This study demonstrated that the cranial vault deformity in DP is associated with facial asymmetry. Compared with the control group, the infants with DP were found to have prominent asymmetry of the nose and mandible.

The purpose of this study was to obtain baseline data on dietary management of women's constipation. We estimated the prevalence of self reported constipation, bowel habits and foods & nutrients intake. The subjects were 169 female college students (normal = 92, constipation group = 77) aged 19 to 23 years. We conducted anthropometric measurements, an evacuation habits survey, and a dietary intake assessment for three days by a 24 hour recall method. The prevalence of self reported constipation was 46% (n = 77). Results showed that bowel habits (the difficulty of evacuation, the duration of evacuation and the feeling after evacuation) were significantly different between the two groups. Over 65% of constipation group used laxatives for constipation relief. Frequency of stress and deep sleeping were related with constipation. In daily food consumption and nutrients intake, there was not a significant difference between the groups. However in relation to bowel habits which factors influence constipation, the study showed that the intake of water, potatoes, kimchi, and fruits correlated with evacuation facility. Further, there were no findings in the difference of foods consumption and nutrients intake between the two groups. But some life style changes and food intakes (potato and kimchi) may be useful to improve constipation symptoms in young women.

This study was conducted to investigate the effectiveness of a nutrition and exercise education program on weight control and nutrition knowledge. The nutrition-exercise educational period was 12 weeks. The subjects were 160 adult women with an average age of 48.1 years. We investigated general characteristics, diet history, eating habits, and intake frequencies of six food groups by survey. A total of 94 women among the subjects participated in the pre and post nutrition knowledge evaluations and anthropometric data assessment. After the program, body weight, body mass index (BMI), and waist circumference significantly decreased. Further, % of body fat decreased, but not significantly. BMI significantly decreased (p<0.001) from 25.14 to $24.80kg/m^2$, and waist circumference significantly decreased (p<0.001) from 79.72 to 77.63 cm. The nutrition knowledge scores of subjects significantly increased (p<0.001) from 8.01 to 9.03. However, there was little change in employment. These results suggest that the nutrition-exercise education program may improve obesity index and nutrition knowledge. However, it is necessary to develop a specialized weight control program for workers.

The objective of this study was to determine whether there are differences in hand muscle activities (APB : abductor pollicis brevis, ED : extensor digitorum, ECU : extensor carpi ulnaris, and EI : extensor indicis) and subjective discomfort according to the three mouse sizes (small, medium, large) and two task types (pointing and scrolling). The mouse size and task type showed significant interaction effects on the total NEMG (p = 0.004) and on the NEMG of the abductor pollicis brevis muscle (p = 0.001). The total NEMG and the NEMG of APB showed the highest value in the 'scrolling' task using the 'small' mouse. However, the NEMG of the EI was different according to the mouse size, and the 'small' mouse showed the lowest value. The subjective discomfort was the lowest in the 'medium' mouse, and all nine subjects preferred the 'medium' size. The hand-size related anthropometric variables showed different correlations according to the task type and mouse size with the NEMGs and subjective discomfort. The results of this study could be used as a basic information for the determination of the proper mouse size according to the hand size.

The purpose of the study is to assess and evaluate methods employed in nutrition surveys and to give an information on methodological considerations for future studies in Korea. Three hundred thirty six papers of nutritional surveys published from 1960 to 1990 were classified into 9 groups according to the survey subject and analyzed for methods used in survey. The frequency of publications according to the survey subject was as the following order : 'in-fants and preschool children' 'school age children' 'adolescence' 'college students' 'preg-nant and lactating women' 'housewives' 'the elderly' 'workers' and 'patients' Eighty five percents of papers applied methods of dietary assessment. of which weighing method recall method an record method were extensively used in the order. Questionnairs included items related to nutrition such as food habit nutrition knowledge etc. Anthropometric techniques were employed in 53% of papers and in general growth measurement were undertaken for children and body composition was emphasized for adults. biochemical assessment was limited to 32% of papers and assessment of anemia was the major test. Clinical studies were applied to 26% of the studies. of which only 5% employed examination of clinical signs of malnutrition Recently self-reported health status assessed using questionnaires has been adopted frequently. Further researches are required for evaluation of the methods employed in nutrition surveys in order to develop the standard model for nutrtion survey so that obtained data can become more reliable and utilized efficiently.

The population aged 95 years and older in Seoul approximately increased to five-fold over the past 10 years, while nationwide rates increased to three-fold. In order to examine the dietary habit and nutritional status of oldest-old population living in Seoul, we recruited 87 subjects (25 males and 62 females) aged 95 years and older. The prevalence of underweight (BMI < 18.5 $kg/m^2$) and obesity (BMI ${\geq}25kg/m^2$) were 18.2% and 18.2% in males, and 20.8% and 9.4% in females, respectively. In self-assessment of health, only 25.3% answered to be unhealthy. More males exercised regularly and reported a wide range of activities than females. The average of %Kcal from carbohydrate, protein and fat (C : P : F) was 64.9 : 13.8 : 21.2 in males and 68.1 : 14.2 : 17.7 in females. The average daily energy intake was 1,307 kcal in males and 1,304 kcal in females. More than 75% of subjects were taking under estimated average requirements (EAR) for vitamin $B_1$, $B_2$ & C and Ca. The average of mean adequacy ratio (MAR) was 0.66 in males and 0.70 in females, and 28.8% of males and 12.9% of females were in MAR < 0.50. Based on MAR, 32.0% of males and 14.5% females were classified as normal and 16.0% of males and 25.8% of females were classified as malnourished. Our subjects were taking more animal food, especially milk and its products, compared to those living, in rural areas. However, a significant proportion did not meet the EAR for vitamin $B_1$, $B_2$ & C and Ca.

The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin $B_2$ (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.
