The early stage of 3D anthropometry data has been used to obtain qualitative rather than quantitative information. However recent 3D body scanners as a common research tool for anthropormatric measurments have made it possible to obtain body surface data of sufficient resolution and accuracy. The purpose of this study is finally to develop motorcycle jacket for enhanced comfort and fit, to test the accuracy and reliability of 3D measurments of motorcycle riding posture, and to analyze the change in 20's adult male's body surface measurements between the standard anthropometric position and motorcycle riding posture. The results of this study were as follows: There were no significant differences between the study and Size Korea measurments in total traditional measuring items and most of measuring items, such as length, circumference antropometric items and interscye items though not waist back length and upper arm circumference. A comparison of 3D body surface measurments in the two different measuring postures, the bodysurface measurments such as waist front length, biacromion length, front interscye, arm length, underarm length in the motorcycle riding posture decreased than that in basic posture, whereas waist back length, back interscye, C.T.W length increased. The body surface measurments such as chest, bust, upper circumference in the motorcycle riding posture decreased than that in basic posture, whereas neck, waist, hip, elbow circumference increased.

The study with the subjects at 200 adult males in Busan in their 20s had a purpose at analyzing lateral body shapes to develop men's educational dress forms. The following are the conclusions: 1. Comparison at the Body Dimensions at Busan Male Adults in Their 20s and the 5th Survey at Korean Body Measurement In the comparison at the Busan and national body dimensions by way at Mollison's relative deviation, all compared items were under the deviation of 0.7. Therefore, the sample of Busan male grown-ups is understood io represent the body shapes of the average Korean male adults in their 20s. 2. Results of Lateral Body Shape Classification From factor analysis, seven factors were produced to explain 75.45% of all variables. Those 7 factors to compose lateral body shapes were hip prominence, back-neck sides, upper body's front-back depth, lateral upper body depth, hip-waist depth, front chest-waist depth, and hip and waist height. Cluster analysis revealed four characteristic lateral body shapes. Type 1 with the appearance rate of 11.70%, named D, had the greatest upper chest angle and tanterior neck lower angle. The front side was more developed. Type 2 with 33.51%, named I, was generally long and slender. Type 3 with 24.47%, named d, had the biggest depth differences in hip-chest as well as more prominent back hip. Type 4 with 30.32%, named q, had the biggest dorsal upper angle and the tiniest chest upper angle as the back area was a little bent.

Larval development, adult longevity and oviposition of the beet armyworm, Spodoptera exigua H bner was studied at 16, 20, 25 and 3$0^{\circ}C$ with a 16L: 8D photoperiod. Egg hatchability of S. exigua was the highest at 3$0^{\circ}C$ and reduced with decreasing temperature. Egg period was the shortest at 3$0^{\circ}C$ and prolonged with decreasing temperature. Percent pupation was became higher at higher temperature form 23.2% to 94.0%. Developmental period of larva was the shortest at 3$0^{\circ}C$, but extended with decreasing temperature. Adult emergence ratio was the highest at 3$0^{\circ}C$ and reduced with decreasing temperature. The mean pupal period was 35.2, 14.4, 7.8 and 5.0 days at 16, 20, 25 and 3$0^{\circ}C$, respectively. Relationships between constant temperature and the developmental velocity of egg, larva and pupa were linear. Developmental threshold temperature seems to be 13.3 8$^{\circ}C$ for egg, 14.02$^{\circ}C$ for larva, 14.09$^{\circ}C$ for pupa, and 13.84$^{\circ}C$ for egg the adult. Estimated value of the total effective temperature for completing each stage was 36.89 day-degree for egg, 155.72 day-degree for larva, 79.20 day-degree for pupa, and 273.41 day-degree for egg to adult. Female longevity varied to temperature from 11.4 days at 16$^{\circ}C$ to 5.8 days at 3$0^{\circ}C$, and male longevity was longer than that of female. Preoviposition period was the shortest at 3$0^{\circ}C$, but prolonged with decreasing temperature. It was about 2.7 times longer at 16$^{\circ}C$ than that at 3$0^{\circ}C$. Number of eggs per female was the highest at $25^{\circ}C$, followed by 20, 30 and 16$^{\circ}C$.

The objective of this study was to investigate the fit preference for ready-to-wear clothes(jackets and slacks) of adult men and to determine the respective differences by the age range and obesity level. The study method was a questionnaire survey with 465 male subjects aged from 20 to 59 years old. The questionnaire was composed of fit preference tendency, physical measurements, age, and occupation. The findings were as follows. 1. Regarding the fit preferred for each part of jackets and slacks, among ready-to-wears, the 'thing with some extra width' in every part was most favored, followed by the 'thing fitting perfectly'. 2. Differences were found in the fit preference tendency by the age of adult men. The fit preference tendency was higher among those in their 20's than among those of the other age ranges. 3. Differences were also found in the fit preference tendency by the obesity level of adult men. The fit preference tendency was higher in the order of the emaciation, normalcy, and obesity types. 4. The fit preference tendency was more affected by age than by obesity level. Clothing companies should consider ease to offer the proper clothing desired by consumers.

This research examined the method and amount changes of recommended protein intakes(RPI) for male and female adult, and pregnant lactating women from 1962's Recommended Dietary Allowances for Korean(KRDA) to 2010's Dietary Reference Intakes for Koreans(KDRIs) revised. As male and female adult's RPI calculation, factorial method was applied until 1989 KRDA, after that nitrogen balance study was applied. Basal factor in factorial method was standard protein(egg or milk protein) requirement or obligatory nitrogen(protein) loss. On the other hand, basal factor in nitrogen balance study was minimum dietary protein requirement to maintain nitrogen equilibrium balance(nitrogen intake = nitrogen excretion). Adjusting factors of RPI were stress and/or protein requirement difference among people. The RPI of male adults were 50~80 g/day, that of female adults were 45~70 g/day. The additional RPI of pregnant women were 10~30 g/day, were calculate based upon the extra protein needs caused by unborn child development. The pregnant women's additional RPI of 2010's KDRIs revised in the periods of first, second, and third trimester were 0, 15, 30 g/day, respectively. The additional RPI of lactation women were 20~30 g/day, were calculated based upon the extra protein needs caused by maternal milk secretion.

Nutritional anemias are an important nutritional problem affecting large population groups in most developing countries. Many reports on investigations of nutritional anemias have been published and there is good evidence that prevalence of iron deficiency anemias in vulnerable groups is high in many areas of the world. However, there is a general lack of accurate data on its prevalence throughout the world. Methods used to measure different factors have been variable and often of poor quality. Furthermore recent comparison of values obtained in different laboratories have shown a much greater discrepancy in iron binding capacity measurements as compared with serum iron determinations. Since the major cause of these differences appears related to the technique employed, the efforts of the central laboratory will be directed initially to standardization of methodology. My laboratory has been joined interlaboratory comparison of WHO studies of iron standardization. The determination of serum iron, iron-binding capacity and transferrin saturation was done on healthy adults, 79 males and 20 females, who visited hospital for health certificate from January to July 1970. The serum iron was determined by the method of modification of Bothwell and Mallett and total iron blinding capacity by Ramsay method and Bothwell and Mallett method. The results of this study are as follows; 1) The serum iron concentration of seventy nine adult male by the method presented is $131.5{\pm}37.3{\mu}g/100ml\;(range\;52.5{\sim}225.0{\mu}g/100ml)$ and of twenty female adult is $108.5{\pm}40.2{\mu}g/100ml\;(range\;45.0{\sim}202.5{\mu}g/100ml)$. 2) The adult male level of serum iron-binding capacity is $330.9{\pm}48.9{\mu}g/100ml\;and\;adult\;female\;is\;291.2{\pm}55.2{\mu}g/100ml$. 3) The transferring saturation of healthy male is $35.6{\pm}12.8%\;(range\;15.1{\sim}18.0%)\;and\;of\;female\;as\;25.4{\pm}12.4%\;(range\;10.1{\sim}60.0)$.

High fructose diet is associated with the global metabolic syndrome (MtS) pandemic. MtS develops in early life, depending on prenatal and postnatal nutritional status. We hypothesized that ovariectomy increases the chances of developing MtS in adult offspring following high fructose intake by the mother. Pregnant C57BL/6J mouse dams drank water with or without 20% fructose during pregnancy and lactation. After weaning, the pups were fed regular chow. The offspring were evaluated until they were 7 months of age after the mice in each group, both sexes, were gonadectomized at 4 weeks of age. The offspring (both sexes) of the dams who had high fructose intake developed MtS. In the offspring of dams who drank tap water, orchiectomy increased the body weight gain and body fat accumulation, while ovariectomy increased the body fat accumulation as compared to the sham controls. In the offspring of dams with high fructose intake, orchiectomy decreased the body weight gain, body fat accumulation, visceral adiposity, and glucose intolerance, while ovariectomy exacerbated all of them as compared to the sham operations. These data indicate that ovariectomy encourages the development of MtS in adult offspring after maternal high fructose intake, while orchiectomy prevents the development of MtS. The sex difference indicates that male and female sex hormones play contradictory roles in the development of MtS.

Purpose: This study is intended to compare musculoskeletal characteristics and Bone Mineral Density (BMD)-related factors between male and female students in a university. Methods: This descriptive study used self-report questionnaires and physical measurements to collect data. Subjects were 64 male and 67 female university students. The questionnaires asked BMD-related factors such as diet, exercise, mental health, and lifestyle. Data were analyzed using descriptive statistics, t-test, $x^2$-test, Fisher's exact test and correlation analysis. Results: The male group showed better back strength, balance, endurance, physical activity, and musculoskeletal health management than the female group. Depression and smoking rates were higher in the male group than in the female group. No difference was found in diet between the two groups. Conclusion: The results suggest to develop gender-specific strategies to increase BMD in university students.
