This study was performed to show change of fat-free mass(FFM), representing mostly the muscle mass change, and muscle strength with increasing age, and relationship between dietary, exercise behaviors and FFM in healthy middle-and old aged women who are of age over 55 years. The FFM and correspondingly hand grip strength showed significant positive correlation with age. But concentration of serum albumin showed no significant relationship with age. The subjects were categorized into groups according to FFM tertile. The anthropometry such as weight, BMI, fat mass, circumferences of waist and hip, WHR, and hand grip strength decreased significantly in the lowest FFM group. But the albumin level showed no change according to FFM level. The FFM showed significant correlation with nutrient intakes such as energy, carbohydrate, protein, Fe, P, Ca. No association, however, was shown with exercise behavior probably because of no case with resistance exercise habits. The variance of FFM was explained 55.2% by height and carbohydrate intake. The variance of height-adjusted FFM could be explained only 16.2% by intake amount of carbohydrate. In conclusion, the decrease of FFM may cause to reduce muscle strength in female elderly. The increasing nutrient intakes were associated with the increased FFM and may protect from risk of sarcopenia. However, only the carbohydrate intake could influence independently the FFM in middle- and old-aged women. The FFM has no association with endurance exercise habits.

This study was accomplished to investigate the prevalence of obesity and the factors related to obesity of high school girls in the large cities from May 20 to July 10 1990. In this study, three hundred eighty nine high school girls were chosen from high schools located in Seoul and Inchon. Anthropometry including weight, height, and skinfold thickness (triceps) were measured, and dietary intakes were calculated according to food composition tables. Means of the obesity index, food pattern, nutrients intakes were compared by Pearson's correlation coefficient. Nutrient intakes of the groups categorized by tricep skinfold thickness were compared by means of Duncan's multiple range test. Prevalence of obesity was 16.7%, 3.6%, and 20.8% by criteria of skinflod thickness, BMI, and Rohrer Index, respectively. Most of the subjects had three meals and took snacks two times per day 23.9% of the subjects were taking nutrient supplements of which vitamin supplement was the most popular. Food habit of subjects such as frequency of snack and bedtime meal were positively related to fatness. Nutrient intakes of the obese groups classified by tricep skinfold thickness, tended to consume more calories than another tricep category groups. Therefore, it could be concluded that prevalence of obesity in this subject was higher than the one for the past years, and it was more profound in girls who had a poor food habits and high calorie intakes. Thus, these results suggested that a good food habits and adequate nutrient intakes are essential to prevent the obesity of high school girls.

This research analyzed the iron status, clinical symptoms and physical characteristics between normal and anemic group of middle school girls in the Ulsan metropolitan area. It was carried out with 237 subjects (normal 190, anemic subject 47). They were evaluated with a questionnaire and measurement of hematological indices. BMI $(kg/m^2)$ of the two groups were $19.54{\pm}2.44$ (normal girls) and $19.22{\pm}2.27$ (anemic girls). The hemoglobin concentration of the anemic girls were $10.84{\pm}1.17g/dl$ and the serum iron of the anemic girls represent $35.15{\pm}27.47{\mu}g/100ml$. The TIBC (Total Iron Binding Capacity) of the anemic girls showed significantly high to $449.30{\pm}64.87{\mu}g/100ml$. The serum ferritin of the anemic girls was $20.53{\pm}42.29{\mu}g\ell$, it represented significantly low. The symptom of 'pale face' of the anemic girls were higher than the normal girls. Hemoglobin and serum iron were negatively correlated with 'pale face'. The TIBC was negatively correlated with 'Get a cold easily'. The duration and amount of menstruation were correlated with iron status. This research is to be utilized as basic data for dietary support and nutritional education to improve their iron status.

The present study was conducted to investigate physical characteristics, food habits of pregnant women with gestational diabetes mellites(GDM). The subjects were consecutive pregnant women, 21 GDM and 43 non-GDM controls who received antenatal care at the Obstetrics and Gynecology clinic. There were no significant difference in the mean age between the two groups(GDM:30.8years, non-GDM:30.5years). Significant differences were observed in several anthropometric characteristics such as height(GDM:159.7cm, non-GDM:162.3cm), prepregnancy weight(GDM:61.6kg, non-GDM:54.1kg), body mass index(GDM:23.9kg/$m^2$, non-GDM:20.5kg/$m^2$), and triceps skin fold thicknesses(GDM:30.9mm, non-GDM:24.7mm) between the two groups. The GDM group had an high incidence of(52.4%) family history of diabetes mellitus than those of control group(23.3%). In the GDM group, more irregularities of meals and more bed-time snacking were observed than those of control group. The intake amount of carbohydrates as well as the total energy were significantly higher in the GDM group when thery were compared with the control. These results suggest that the GDM women in Korea do exhibit clearly distinctive anthropometric and dietary characteristics. Nutritional management such as weight control before conception and throughout pregnancy, monitoring total energy and carbohydrate intakes, and implementing more rigorous meal scheduling might be beneficial for the prevention or reduction of the prevalence of the GDM or its complications.

The present study analyzed data from the 3D measurement of the feet of men aged over 20 years residing in the capital region as part of the 6th Anthropometry of Size Korea. To analyze the characteristics of the foot shapes of young men aged 20~39 years and middle-aged/elderly men aged 40~69 years by age and by type, a cluster analysis was conducted using the factors derived through the factor analysis as independent variables. The results of the study that analyzed the characteristics of foot shapes by type according to differences in age were as follows. First, through the analysis of the characteristics of the foot shapes of young men by type, five factors were extracted, and the foot shapes were classified into three types: Type 1 (short and flat), Type 2 (thick), and Type 3 (long and wide). Second, through the analysis of the characteristics of the foot shapes of middle-aged/elderly men by type, six factors were extracted, and the foot shapes were classified into four types: Type 1 (short and regular), Type 2 (flat), Type 3 (thick), and Type 4 (long and regular). The results of the present study are expected to serve as basic data for the design of shoes by age and foot type.

The purpose of this study is to examine differences between real somatotypes and cog-nitive somatotypes by considering the degree of satisfaction of body parts. The subjects were 250 middle-aged women from 40-54. Data was collected through anthropometry and surveys. Data was analyzed by correlation analysis anova duncan multiple range test factor analysis regression analysis crosstabulation analysis. The results were as follows: 1. Middle-aged women tend to prefer having a slim truck long and slim limbs and their hope was to be tall in height and light in weight slim at the waist and abdomen. 2. The consciousness about thickness was in-tensified more than that about length of the body. 3. The slim somatotype group were more satisfied with their body than those of obese somatotype group. 4. The average R hrer Index of middle-aged women is 1.55 and the slim somatotype group is 1.33 and the standard somatotype group is 1.53 obese somatotype group is 1.82. Age has much influence on the body change of middle-aged women. Especially 45-49 years old the slim body type declined heavily. 5. When analyzing the elements of body sat-isfaction the biggest elements are in the sub-ject of girth related to the expansion of trunk. Therefore trunk girth has more influence on body satisfaction than height and limbs. So the obession of trunk girth is the most important factor in body satisfaction. 6. Most middle-aged women although not judged to be obese by measurements believed themselves to be obese.

To customize individual characteristics of HRTF, a spherical model has been used for structural modeling technique. A pseudo-code of prolate spheroidal HRTF caused by incident acoustic point source is already developed, and it can be used a head shadow filter for structural modeling of HRTF. In this research, to see the necessity and efficiency of spheroidal head modeling, ITD optimization is performed on CIPIC HRTF database. From given cost function, ITD-optimized spheroidal head model, whose ITD information is the most matched version of measured ITD information, is found by varying head parameters subject by subject. By comparing results of ITD-optimized spheroids and ITD-optimized spheres, we concluded that a spherical head model is more efficient way of generating head shadow effect than a spheroidal head model does.

The purpose of this study : 1. The total 56 range measurements of active dynamic motion of 40 subjects (20's and 30's) were measured using 3-D dynamic motion analysis system. 2. Various comparisons were performed for the right and left side, male, age groups (20's, 30's, and 40's ∼ 60's) using previous studies. The results were compared with the other studies in the aspects of age. In this study, the 3-D motion analysis system based on photogrammetry was established and used to analyze the human's motion and posture. The system consists of VICON 140, data acquisition system, and data analysis program (KRISSMAS). The result of this study were as follows : 1. Comparing 20's with 30's the result shows that 30's have larger ROM at some joints, which is inconsistent with the previous result. The reason is that female subjects in 20's were improperly sampled according to the representatives of anthropometry characteristics. 2. There are significant differences in some joints related with age. 20's male subjects have more flexible joints in the neck while 30's male subjects have more flexibility in their shoulder joint and elbow joint. But most of the significances were not high (p〈0.05). The prediction that the right side of Korean bodies would be more flexible was not a good hypothesis. And the joints flexibilities are not correlated with Rohrer's Index.

Critically ill patients admitted in ICU and NCU were studied with respect to their nutritional status and support to them at initial period, and the effect of nutritional support after 3 weeks. The nutritional support was supplied to these patients with the enteral and parenteral nutrition. The results of biochemical test and status of nutritional support on 52(29 males, 23 females) critically ill patients were based on medical records and the anthropometry was measured on 28 patients. The subjects were in mild malnutrition. Their initial calorie intakes were 85% of BEE, 57% of total energy requirements and 49% of protein requirement were provided. Two groups, one group of serum albumin level more than 3.5g/dl and the other group of serum albumin level less than 3.5g/dl, were significant different in total calorie and protein intakes. After 3 weeks, inappropriate nutritional support in the group of normal nutrition results in significant decreasing of serum albumin level but, there were no changes in the group of malnutrition. Nutritional support is one of the mainstays in the management of these critically ill patients and is aimed at preventing malnutrition. Therefore, timely nutritional support is heavily required in cases of critically ill patients whether their initial nutritional status is normal or not.

Objective: The aim of this study is to investigate the attributing factors influencing major research areas of the papers published in the journal of Ergonomics Society of Korea (JESK). Background: Ergonomics has a wide range of research areas. Diversity of research topic is one of the major strong points of this discipline especially in the era of fusion. Dominant areas among the diversity changed from time to time. It is interesting to know the attributing factors of the dominant areas. Method: During the past three decades JESK has published 649 articles. As an editor of the JESK, I reviewed these papers and sorted them into the detailed research fields of ergonomics; (1) technical group (TG) s of the Human Factors and Ergonomics Society (HFES), (2) editing groups of the journal of Ergonomics Abstracts and (3) TGs of the Ergonomics Society of Korea (ESK). I also listed major events which might affect the publication trend. Results: Anthropometry was the most dominant area all the time. Health and safety area has been steadily increasing publication amount. Conclusion: Government research funding was the main attributing factor determining the publication trend of the JESK. Application: The results of the publishing trend analysis might help to determine the editing policy of the JESK.
