The objective of this study was to elucidate the basis for the difference in sperm production of broiler breeders. Nine sexually mature Hubbard broiler breeder males, 35 weeks of age, were trained for two weeks for semen collection on alternate days by abdominal massage technique. Following the training, the breeder males were collected daily for five successive days. The males were then classified as low or high sperm producers. The mean body weights of individual males were also recorded on the basis of body weight at the start and end of the experiment. Immediately after last collection the males were slaughtered and testes biometry was determined. Daily sperm output of individual males varied from $0.21{\times}10^9\;to\;2.64{\times}10^9$ sperm. The daily sperm production of low sperm producer males was lower ($0.47{\pm}0.13\;vs.\;2.06{\pm}0.20{\times}10^9$; P<0.05) than high sperm producer males. Testes weight of low sperm producer males was lower ($6.32{\pm}1.6\;vs.\;20.33{\pm}4.76\;gm$; P<0.05) than high sperm producer males. Moreover the testis weight of high sperm producer males was 3.22 times higher than low sperm producer males. The average body weight of high sperm producer males was higher ($4,389{\pm}116.3\;vs.\;3,960{\pm}131.77\;gm$; P>0.05) than low sperm producer males. The correlation coefficients indicate significantly positive correlation of body weight (P<0.05) and testes weight (P<0.01) on semen volume, sperm concentration and daily sperm production.

The purpose of this study is to grasp the actual condition toward the clothing of senior males' and perception of male's formal wear companies for silver market through a survey targeting senior males and clothing companies. The survey was conducted targeting 196 senior males and chief-patterners of 7 companies' 10 brands. The questionnaire distributed to senior males was consisted of 22 items regarding the perception and satisfaction on clothes. And 12 items concerning the perception of senior male clothing brands and the size system was developed for clothing companies. The results of the study are as follows. The study revealed that most senior males perceived that brand clothing for them was necessary. More than half of the respondents were not satisfied with ready-made clothes. And many senior males prefer ready-made clothing when they purchase their clothes. For these reasons, senior males apparel market might be promising. Currently, the perception of male's formal wear companies on the need of brand was high. However, considering that brand launching might be difficult to be realized soon I presume that size spectrum based on body size of senior males is necessary which reflect their physical characteristics and activities.

This study was conducted to offer basic data that can be used in a clothing industry for active senior males that are emerging as a new consumer bracket in a rapid aging age. To this end, this study conducted an analysis of 'younger' older male body types based on data from the 6th Size Korea. As a result of the body type analysis of 'younger' older males who are considered active seniors in comparison to 'middle' aged males, the former's height items became shorter compared to 'middle' aged males, but circumference items were bigger. Males aged 35-69, who are 'middle' aged males and 'younger' old males were divided into three body types in this study: Type1- small body type with protruded belly, compared to weight. Type 2- body type of slim torso with wide shoulder-back widths. Type3- big body type overall with tall height and heavy weight. According to body type distribution by age group, the middle-aged males had Type2 body type the most. The younger-old males showed type1 the most. There is a need to reflect the body types of active senior male characteristics in apparel pattern design because the current fits are not appropriate if active senior males wear clothing targeted for males aged 30-50.

The frequencies of finger print patterns and the pattern intensity index among 2, 925 Koreans (804 males, 2, 121 females) are analyzed. Total finger ridge counts was calculated for 776 Koreans (426 males and 350 females). Comparisons are made with results among other racial populations in a review of the literature. Certain differences exist between males and females in both qualitative (finger print pattern) and quantitative (total ridge count) dermatoglyphic traits. Males have higher frequences of whorls (53.6% for males, 45.7% for females), and radial loops (2.9% for males, 2.2% for females), while the frequencies of archs (1.9% for males, 2.9% for females) and ulnar loops (41.6% for males, 49.2% for females) are higher in females. The pattern intensity index for males (15.2) was higher than that for females (14.3). The mean of the total ridge count was higher (140.4$\\pm$41.2) in males than in females (129.8$\\pm$40.6). There was no correlation between total ridge count and IQ (r=-0.0027, N=343). Total ridge count among different racial groups was found to vary slightly.

Purpose: Hip rotation testing is important in the evaluation of chronic back pain. The purpose of this study was to investigate hip and lumbopelvic movement during hip medial rotation (HMR) in individuals with chronic lower back pain (CLBP). Methods: This study targeted 112 subjects in total: 28 healthy males and 28 healthy females, and 27 males with CLBP and 29 females with CLBP. Motion-capture device was used to measure the hip medial rotation angle (HMRA), lumbopelvic rotation angle (LPRA), and the rotation angle of the hip when lumbopelvic rotation starts during hip medial rotation. Results: When evaluating the healthy males and females using the hip medial rotation test (HMRT), healthy males showed a smaller HMRA than did healthy females (p<0.05). When evaluating the healthy males and the males with CLBP using the HMRT, males with CLBP showed a smaller HMRA and more lumbopelvic movements than did healthy males (p<0.05) in addition, their lumbopelvic movements occurred earlier during HMR (p<0.05). Finally, when evaluating the males and the females with CLBP using the HMRT, males with CLBP showed a smaller HMRA and more lumbopelvic movements (p<0.05), and their lumbopelvic movements occurred earlier during HMR (p<0.05). Conclusion: The HMRT is an important test for the evaluation of males, and especially males with CLBP, as they often experience an increased LPRA and decreased HMRA, with lumbopelvic movement occurring earlier during HMR when compared to other groups.

To investigate the comparison of dietary status and health behaviors according to obesity, 239 male workers were selected and classified as normal (18.5-22.9 27.2%), overweight (23-24.9, 37.7%), and obese (25-29.9, 35.2%) by body mass index ($kg/m^2$). The SAS (ver. 9.2) program was used and verified by the chi-square and f-value methods. Drinking frequency(2-3 times a week) was higher in normal males(45.3%), but not as high as in obese males (48.1%) (p<0.001). Smoking frequency and amount were the highest in overweight males, but not-quit-smoking was high in obese males(51.9%) (p<0.001). Exercise time was longer in normal males(108 minutes) than other groups(69 overweight males, and 82 obese males (p<0.01). Obese groups(73.8%) slept well (p<0.001), but overweight males(44.4%) showed less than 6 hours of sleep (p<0.01). Meal frequency differed by group(two meals a day 67.7% in normal males (p<0.001), no-snack 65.5% in obese males(p<0.001). The frequency of eating-out was once a day in normal males (38.5%), differed in the eating-out time (lunch(45.8%) in normal males, dinner in overweight males(52.1%) and obese males(59.5%) (p<0.01). Korean food (49.3%) was selected, but noodle differed by group(10.2% normal 21.5% obese (p<0.01). Self-perception of body differed from the body's actual condition(p<0.001). For weight control, exercise(56.4%) was practiced more than diet(18.6%). Nutrition knowledge was poor (correct answer rate was 36.7% in normal males, 41.7% in overweight males, and 46.7% in obese males). For eating attitudes, obese males answered more in "flexible to change eating habits", "supplemented when poor eating"(p<0.001), normal responded in "impact on nutrition to health", "try new food for health"(p<0.01). From these results, it is evident that male workers, especially overweight ones, must work to learn more about health and nutrition so as to combat chronic diseases.

This study was undertaken to examine the levels of serum lipids and lipoproteins of college students and the correlations between serum lipid levels and food habits. 202 college students(99 males and 103 females) were selected as subjects for this study during November, 1993. The mean height and weight were 173.2 cm, 63.7 kg for males and 159.4 cm, 50.8 kg for females, respectively. The mean serum TC, LDL-C, HDL-C, TG levels were 172.2, 103.4, 52.3 and 82.3 for males and 182.4, 111.6, 56.3 and 72.5 mg 161 for females, respectively. Serum lipid levels of males were significantly lower than those of females except TG. There was no significant difference In TG levels between males and females. Food habit scores of females were significantly higher than those of males. The significantly different items between males and females were numbers of daily meal intake, duration of meal intake, regular daily Intakes of cereals, fruits, vegetables and animal fat, exercise, alcohol intake and smoking. Food habit score of Items except exercise in females were higher than those of items in males. LDL-C and LPH were positively correlated with food habit score. TC and LDL-C were positively correlated with eating-out, alcohol intake, smoking but negatively correlated with numbers of daily meal intake. HDL-C was positively correlated with overeating, but negatively correlated with cholesterol intake. There was no significant correlation between TG and food habit items. Regular meal intake was positively correlated to LPH by having a negative correlation with HDL-C in males and regular daily intake of cereal was positively correlated to LPH by haying a positive correlation with LDL-C in females. There were significant correlation between food habits and anthropometric measurements. Height and weight were positively correlated with daily meal intake and exercise but negatively correlated with duration of meal intake, daily intakes of cereals, vegetables fruits and animal fat, smoking, alcohol intake. Smoking was negatively correlated with height and weight in males, over-eating was negatively correlated with height in females. Finally this study showed an interesting results that balanced intake of five basic food groups were positively correlated with weight in males but with height in females.

The purpose of this research is to offer basic data for the elderly males and females's clothes design and pattern making through the questionnaires on the actual condition of their clothing life. The subject of research were 111 elderly males and 120 elderly females who aged between 60 and 79 in Pusan. The results are as follows: The elderly females take more interest in clothes and set a higher value on influence of clothes than males. The elderly males and females are extremely discontented with high price of store clothes. And most of them consider that store clothes are not suitable for their body, so it is necessary that dress shops to take a target for the aged. Princepally the elderly males do their shopping with their wives but the elderly females by themselves in a department store. When their purchasing clothes, the elderly males bear in mind 'size' but the elderly females 'design' in the highest priority. The elderly females have exacter idea of their size than males. But after buying their store clothes, most of the elderly males and females mend their clothes.

Fingerprints of 114 Australian Aboriginal males and 90 females have been analyzed. Whorls are more frequent in males (56.7%) than in females (51.2%) and loops are less frequent in males (42.6%) than in females (47.0%). The index of pattern intensity displays a higher value in males (15.60) than in females (14.94). The bimanual differences both in males and females ave not statistically significant for the occurrence of patterns on the digits of the right and left hands. Also the difference between both sexes for the occurrence of patterns is not statistically significant. Incidences of actual symmetry on homologous digits represented 74.0% in males and 77.3% in females. The mean total ridge counts showed 156.65 $\pm$43.32 (M$\pmSD) in males and 148.6943.64 (M$\pmSD) in females, respectively. Conclusively, this study represents that the Australian Aborigines conform closely to the Polynesians in finger dermatoglyphics.
