A deteriorating North Korean economy, coupled with a devastating natural disaster such as flooding and drought in recent years, brought about a severe food shortage and malnutrition problem which caused a migration of its population including young children to neighboring countries. We conducted a nutritional survey on a total of 436 children, aged 4-19 years old, who migrated to the China side of the border from July to September, 1999. The study subjects were interviewed by Korean-Chinese interviewers who were trained for anthropometric measurements and dietary surveys. Heights, weights, and chest circumference of the subjects were 70-90% of the South Korean reference values for the corresponding age and sex. Dietary intakes of the subjects were found to be extremely poor-the average number of food, mostly of plant origin, consumed in a day was 2.8, and the proportion of the subject who reported to take all three meals in a day while residing in North Korea was as low as 36.2%. Ninety five percent of the subjects had at least one clinical symptom related to malnutrition, 68.6% had 2-4 symptoms, and 15.1% had 5 or more symptoms. The results of this study provided an objective data for the first time on the severity of the food crisis and malnutrition problem that afflicted North Korean older children and adolescents as well as children aged 7 or under as previously reported elsewhere. the wasted and stunted children and youths prevailing in North Korea could exert a negative influence on the country's health and economy. More researches are needed in the future to investigate on the impact of malnutrition in North Korean children on the country's social, economic, and cultural state as well as on the health and nutrition situation.

The objectives of this study were to obtain normative data for 45 mother-daughter pairs on spine, femur(neck, ward's triangle, trochanter) and total body BMD (bone mineral density) measured by dual energy X-ray absorptiometry, anthropometric measurement, body composition, biochemical markers, nutrient intakes and energy expenditure, to determin the interrelations of these factors within each group, to measure familial resemblance for each variable. We observed significantly positive correlations between height, weight, head, hip and calf circumferences, tricep, femur and calf skinfold thickness, total lean body mass(=weight-total fat body mass-bone mineral content), protein and fat intakes, Ca index, serum total protein and albumin of monter-daughter pairs(p<.05-p<.001). Among mothers, age, osteocalcin, higher, weight, Ca and energy intakes were predictors of BMDs. Among daughters, weight and energy intake were predictors of BMDs. The BMD in lumbar spine(r=.48, p<.01), femoral neck(r=.38, p<.05), ward's triangle(r=.36, p<.05) of the mothers were significantly correlated with those of the daughters, after adjustment for mother's age, hight, weight, osteocalcin, Ca and energy intakes and daughter's weight, energy intake. In regression analyses, mother's BMD also were positively associated with daughter's BMD in lumbar spine, femoral neck, ward's triangle. Our findings support that mothers with low BMD tended to have daughters with low BMD. In the age groups studied, as well genetic factors as environmental factors may have an important role in determining BMD. This study suggests that women may successfully enhance their genetically determined BMD through adequate nutrient intakes and weight bearing exercise.

The objective of this study is to develop a sizing system of fitness clothing that can properly accommodate various body sizes of Korean senior women. The sizing system of upper and lower fitness clothing was developed in the present study by selection of key variables, identification of size category candidates, and determination of an optimal sizing system. First, key anthropometric dimensions (stature and bust circumference for upper clothing and stature; waist circumference for lower clothing) were identified by factor analysis on the direct body measurements (n = 272) and 3D whole-body scan data (n = 271) of Korean senior women in Size Korea. Second, sizing system candidates based on the key dimensions of upper and lower clothing were explored using a grid method and an optimization method. Lastly, among the sizing system candidates, optimal sizing systems of upper and lower clothing were selected in terms of accommodation rate. Five size categories (short/small, short/medium, tall/small, tall/medium, and tall/large) were selected as the optimal sizing systems of upper and lower clothing with 89% and 78% of accommodation rate, respectively, for the Korean senior women. The anthropometric characteristics of the representative humans of the optimal size categories would be of use in the design of fitness compressive wear for the better fit and effectiveness of exercise and health of Korean senior women.

The purpose of this study was to classify the upper torso body types of obese Korean adult women using the 7th Korea National Anthropometric Study data and compare the body type differences according to three age groups: 20s~30s, 40s~50s, and 60s. A total of 548 adult women whose BMI was in the obese range of 25 or higher and whose age ranged from 20s to 60s were selected from the anthropometric database. Twenty-nine body measurements related to torso and arm areas important for torso and sleeve pattern development were chosen. Five drop values by differences between bust, waist, and hip circumferences were also chosen for analysis. The number of obese women increased with age. The results revealed seven factors according to the factor analysis and three obese body types based on the cluster analysis. Body type 1 (47.3% of obese women) was characterized by narrow shoulders, a small or medium torso, and a straight waist. Body type 2 (42.4% of obese women) was characterized by a defined waist and a larger lower torso than upper torso. Body type 3 (10.3% of obese women), the largest obese body type among the three types, was characterized by a large bust, large abdomen area, and long upper torso. Women in their 20s to 30s were most likely to have body type 2, women in their 40s to 50s were evenly distributed between body types 2 and 3, and women in their 60s were most likely to have body type 1.

The aim of this study is to provide fundamental data on the development of ready-to-wear clothing appropriate for the lower body types of male students who play sports in college. The study was conducted by means of targeting 151 male sports majors between $18{\sim}27$ years of age. Characteristics of the respondents were ascertained by means of questionnaires and an evaluation of a total of 36 lower body features. The results of the study are as follows. 1. A comparison of anthropometric measurements with the National Anthropometric Survey of Korea (1997) revealed that the main characteristics of the lower somatotypes of male sports college students are large circumferences and developed muscles of the lower body. 2. Sports were classified into the following five categories : soccer, bodybuilding, wrestling, judo, and taekwondo. In particular, bodybuilding students demonstrated a somatotype with an increased circumference, depth, and width of the thigh and lower body. 3. Somatotypes were classified into 3 types by means of a cluster analysis employing S factors. Type 1 somatotype exhibits a large circumference in the lower body. Type 2 is a lower somatotype of a middle size. Finally, Type 3 encompasses a smaller group in weight and circumference with a developed calf and ankle. 4. Each group was evaluated using a discriminatory analysis as a check to see if the groups had been discriminated with accuracy. The total accuracy rate was 96.0%.

This study investigated the influence of anthropometric data and nutrient intake on bone mineral density(BMD) and biochemical markers of bone metabolism The mean age of 21 premenopausal women were 47.0 years and that of 41 postmenopausal women whose menopausal age was 49.46 years were 60.56 years. The waist and WHR of postmenopausal women were significantly higher than those of premenopausal ones. The animal protein intake of premenopausal and postmenopausal women were 38.5 and 21.03 g which comprised 54.35 and $31.84\%$ of total protein intake, respectively. The calcium intake of premenopausal and postmenopausal women were 446.45 and 546.97mg which was 63.78 and $78.14\%$ of Korean RDA, respectively. The ALP(Alkaline phosphatase) of premenopausal women was 65.81 U/L, which was significantly lower than that(90.24 U/L) of postmenopausal women (p<0.01). BMD of lumbar spine of premenopausal women was correlated significantly with body weight(r=0.690, p<0.01), waist(r=0.682, p<0.01), WHR(r=0.672, p<0.01), BMI(r=0.559, p<0.01), and body fat(r=0.457, p<0.01). Urinary Ca/creatinine ratio of the premenopausal women was negatively correlated with plant protein(r=-0.529, p<0.05) and plant calcium(r=-0.579, p<0.05). BMD of lumbar spine of postmenopausal women showed positive correlation with lean body mass(r=0.469, p<0.01) and body weight(r=0.383, p<0.05). Urinary Ca/creatinine ratio for the postmenopausal women was positively correlated with ALP(r=0.404, p<0.01) and urinary Na/creatinine ratio(r=0.389, p<0.05). In conclusion, it is necessary to maintain adequate body weight and to increase calcium intake for the premenopausal women. It is also important to increase muscle mass and reduce salt intake for the postmenopausal women.

This analysis was performed to investigate the relationship between nutrition and anthropometric indices using the data from a cross-sectional survey of a large national sample, '98 Korean national health and nutrition examination survey. Subjects were selected by stratified multistage probability sampling design and completed dietary questionnares including food intakes for one day by 24-hour recall method. For this analysis, 6566 subjects were selected by age(over 20 years old). For anthropometry, height, weight, and waist- and hip- circumference were measured. They were classified by body mass index(BMI, weight(Kg)/$height^2 $($m^2 $)) and waist-hip ratio(WHR, waist circumference(Cm)/hip circumference(Cm)). The nutrients intake of subjects were compared with the recommended daily allowances(RDA). Mean adequacy ratio(MAR) was calculated. Mean heights, weights, BMIs were higher in the groups with nutrient intake over 125% of RDA than the lower intake groups for most nutrients. However, Mean WHR was the highest in the groups with nutrient intake under 75% of RDA for most nutrients excluding iron intake of women aged 20-64 years. Among women aged 20-64 years, means of MAR were 0.71 for obese individuals(BMI>30), 0.72 for subjects with underweight(BMI<18.5), and 0.76 for subjects with normal weight(18.5$\leq$BMI<25). Normal subjects has statistically significantly higher MAR than those of other groups. However, among elderly people aged over 65 years, obese group had the highest MAR, 0.68. Women with abdominal obesity(WHR>0.9) had lower MAR, 0.71 than those with normal weight(MAR=0.76). From these results, obesity and abdominal obesity seems to be the results of malnutrition including both undernutrition and overnutrition rather than simple problem of excess energy intake. Obesity in elderly people needs to be handled differently from adults.

This study analyses the effects of various angles in sculling on human body lift and drag by means of computational fluid dynamics, discusses the importance of sculling and provides a basis for the development of future water safety education programmes. Study subjects were based on the mean data collected from males in the age of 20s from a survey on the anthropometric dimensions of the Koreans. Moreover, lift, drag as well as coefficient values, all of which were governed by the angle of the palm, were calculated using 3-dimentional modelling produced by computational fluid dynamics programmes i.e. CFD. Interpretations were performed via general k-${\varepsilon}$ turbulence modelling in order to determine lift, drag and coefficient values. Turbulence intensity was set to one per cent as per the figures from preceding research papers and 3-dimentional simulations were performed for a total of five different angles $0^{\circ}$, $15^{\circ}$, $30^{\circ}$, $45^{\circ}$ and $60^{\circ}$. The drag and lift values for the differing angles of the hands during sculling movement are as follows. The lift and drag values gradually increased with the increasing angle of the palm, however, the magnitude of increase for drag started to predominate lift from $45^{\circ}$ and lift gradually decreased from $60^{\circ}$. Overall, it is concluded that the optimal efficiency of sculling can be achieved at the angles $15^{\circ}$ and $30^{\circ}$, and it is anticipated that greater safety and informative education can be ensured for Life saving trainees if the results were to be applied to practical settings. However, as the study was conducted using simulation programmes which performed analyses on the collected anthropometric dimension, the obtained results cannot be made universal, which warrants furthers studies involving varied study subjects with actual measurements taken in water.

The purpose of this study was to investigate the effects of smoking and/or alcohol drinking on the nutrient intake, nutritional status, and eating habits of adult males. The subjects were 157 male adults aged 20-49 living in Daejon. Interviews with questionaire on smoking and alcohol drinking habits and eating habits, anthropometric measurement, biochemical blood test, and dietary assessment by one-day 24 hour recall and two-day diet record were carried out. The subjects were divided into four groups : control (non-smoking and non-drinking), drinking only, smoking only, and the both(drinking and smoking). The average numbers of smoked cigarettes were 17.8/d and 19.1/d in the smoking only group and the both group, respectively. The frequency of alcohol drinking was 8.3 times/month and 11.6 times/month in the drinking only group and the both group, respectively. Height was significantly higher(P 0.05) in the drinking only group than in the none and smoking only groups, while the other anthropometric indices were not different among the four groups. There were positive correlations between smoking and drinking or coffee intake. Alcohol drinking increased eating-out frequency and the intakes of energy, protein, dietary fiber, vitamin A, B$_1$,$ B_6,$ Fe and P, while smoking decreased snack frequency and intakes of energy, protein and vitamin $ B_6,$. Blood pressure was not changed in the smoking only and drinking only groups compared to the none group, while systolic blood pressure was elevated in both group(P 0.05). Alcohol drinking significantly elevated(P 0.05) serum total cholesterol and LDL-cholestrol level, while smoking did not change the serum lipid and cholesterol levels. Hemoglobin nd MCHC levels were significantly elevated(P 0.05) by smoking. From these data, it is suggested that both smoking and drinking have influence on some eating habits and nutrient intakes, and especially alcohol drinking can induce hypercholesterolemia.

The purpose of this study was to assess the iron nutritional status of college women residing in the Kyungin area. The anthropometric parameters, nutrient intake, and biochemical status of iron were measured for 102 college women. The mean height and weight were 160.3cm and 52.4kg, respectively. The proportion of subjects whose BMI was less than 20 was 41.3%. The proportion of subjects assessed as overweight(25$\geq$25%) assessed by the fat percent(FP) was 53.9%. The mean daily intake of iron was 13.90mg(77.1% of RDA), composed of 0.97mg of heme iron and 12.44mg(69.0% of RDA). When the sources of iron were grouped as rice(including bread), noodle, soup, side dish, and snack, noodle provided, 3.95mg of iron regarded as the highest amount. Subjects were taking 6.72mg(51.4% of RDA) of iron per day from main dishes(rice, bread and noodle). The fifty five percent of the subjects showed iron depletion(serum femitin<20ng/ml)and 33.4% showed suppressed erythropoiesis with iron deficiency(serum ferritin<10ng/ml). The anemic subjects assessed with transferrin saturation (<15%) represented 33.3% of the test population, whereas 11.8% of the subjects possessed less than 12g/dl of hemoglobin. Subjects not satisfied with their body shape were having significantly lower amount of energy intake(p<0.05) than the subjects satisfied with their body shape. College women having mothers who graduated from university had a significantly decreased amount of energy, carbohydrates, fat and vitamin C(p<0.05). The mean RBC and serum iron of the subjects who were on a diet more than one month were lower than those of the subjects who were not on a diet(p<0.05).
