The purpose of this study was to compare the differences in recognition of sexy body parts and apparel designs by gender and correlations between sexy body parts and apparel designs. Data were collected through a survey of 265 males and 303 females. Data were analyzed by included t-tests, f-tests, and Pearson's correlations. The results were as follows: 1. Females found male body parts were sexier than males did. Males found female body parts were sexier than females did. 2. Females found men's clothing designs were sexier than males did. Also, males recognized women's clothing designs as sexier than females did. 3. Males found see-through and body-consciousness, the methods of designing sexy styles, were sexier than females did. Differences in sexy color recognition by gender were also found. 4. There were correlations between most of sexy body parts and designs which emphasized that body parts. The results of this study shows the differences in recognition and correlation by gender. The results may be applied to develope sexy designs for different genders.

Several studies on the pronunciation of English vowels point out that Korean learners have difficulty distinguishing English tense and lax vowel pairs. The acoustic comparisons of those studies are mostly based on the formant measurement at one time point of a given vowel section. However, the English lax vowels usually show dynamic changes across their syllable peaks and subjects' English levels account for various conflicting results. The purposes of this paper are to compare the temporal duration and dynamic formant tracks of English tense and lax vowel pairs produced by five Korean and five American males. The subjects were graduate students of an American state university. Results showed that both the Korean and American males produced the vowels with comparable durations. The duration of the front tense-lax vowel pair was longer than that of the back vowel pair. From the formant track comparisons, the American males produced the tense and lax pairs much more distinctly than the Korean male speakers. The results suggest that the Korean males should pay attention to the F1 and F2 movements, i.e., the jaw and tongue movements, in order to match those of the American males. Further studies are recommended on the auditorily acceptable ranges of F2 variation for the lax vowels.

The purpose of this study was to examine the influence of major variables and their relationship with the males' appearance consciousness that affect the men's cosmetic consumption. Also, the study also intended to verify the differences of men's cosmetic consumption between Chinese and Thai males. The samples consisted of 200 males who ranged in age from 18 to 35 years (M=24.64). One hundred participants were Thai and one hundred were Chinese. Based on literature review, six research questions were proposed. For data analysis, descriptive statistics, factor analysis, t-test, and multiple regression were used for this study. As the results, the sociocultural attitudes of consumers towards their appearance are positively relevant to the self-esteem and public self consciousness. Also, appearance consciousness such as appearance evaluation and appearance orientation led more cosmetic consumption. Chinese males revealed higher scores on public self-consciousness, appearance orientation, and sociocultural attitudes toward appearance than Thai males. Based on these results, some implications for global cosmetic markets would be suggested.

The objective of this study was to investigate the physical work capacity and rest allowance for Korean males and females. Eleven males and 13 females participated in the study as subjects. An ergometer exercise test and a treadmill exercise test were conducted to measure oxygen consumption rates. The PWC values of Korean males and females were 2605.62ml/min and 1853.01ml/min in the cycle ergometer test, respectively, and 2872.10ml/min and 2057.91ml/min in the treadmill test. The PWC values of Korean females were about 70% of Korean males. The PWC values of Korean females were74.36%-78.79% of western males in the treadmill test. and 88.66%-89.32% of western males in the ergometer test. The PWC values of Korean females were 81.34%-82.98% of western females in the treadmill test, and 87.11% of western femaleles in the ergometer test. And, the results of this study showed that the rest allowance should be determined separately for male and female because of the difference in physical work capacity.

English vowels can be divided into monophthongs and diphthongs depending on the number of vocal tract shapes. Diphthongs are usually produced with more than one shape. This study attempts to collect acoustical data of English diphthongs published by Hillenbrand et al.(1995) online and to examine acoustic features of the diphthongs for phoneticians and English teachers. Sixty three American males and females were chosen after excluding those subjects with different target vowels or ambiguous formant tracks. The author used Praat to obtain the acoustical data systematically at eleven equidistant timepoints over the diphthongal segment. Obvious errors were corrected based on the spectrographic display of each diphthong. Results show that the formant trajectories of the diphthongs produced by the American males and females appeared quite similar. When the female formant values were uniformly normalized to those of the males, almost a perfect collapse occurred. Secondly, the diphthongal movements on the vowel space appeared not linear due to the coarticulatory gesture for the following consonant. Thirdly, the average duration of the diphthongs produced by the females was 1.156 times longer than that of the males while the pitch ratio between the two groups turned out to be 1.746 with a similar contour over measurement points. The author concludes that English diphthongs produced by various groups can be compared systematically when the acoustical values are obtained at proportional timepoints. Further studies will be desirable on the comparison of English diphthongs produced by native and nonnative speakers.

Five to seven day old pupae were irradiated with gamma rays, the mating ability, and competability of the irradiated males were examined. The results obtained are summarized as follows: 1. There is no difference in percentage of males that mated, nor in the maximum number of matings of the males, when individual matings were made, and fresh females were provided every day for his life time. 2. The average days for the first mating of the emerged were 1.5 days for the control, and 2.4 days for the males irradiated with 25 and 30 Krad. The average days between first and second mating were 3.0 days for the irradiated males, and 1.3 days for the control. 3. The average matings of a male were 1.2 and 2.5 times when 5 and 10 females were provided to a normal male respectively. No significant different in average numbers of mated female per male were observed between the normal and irradiated males. 4. To test the mating competitiveness of the irradiated and normal males (1:0, 1:1, 2:1, 1:2, 5:1, 1:5, 0:1) were confined together with five virgin females. The greatest reduction in hatching percentage was found with 5 : 1 : 1 (30 Krad) where $26.6\%$ was hatched.5, The results showed that the irradiated males were not fully competitive with normal males, but if the reduced number of eggs produced by the female mated with irradiated male is considered, it might be used sterile male techniques in rice stem borer control.

Energy budget of mysid shrimp, Neomysis intermedia in Lake Kyongpo was determined at constant temperature (2$0^{\circ}C$). Energy used by reared mysids were calculated from data on feeding, growth, molting, reproduction, and metabolism. The Energy used by growth of juvenile and adult were 6.87 cal in females of 8.55mm in length, and 5.67 cal in males of 7.53mm in length, respectively. Molting losses were estimated to be 0.46 cal in females and 0.38 cal in males from juvenile to adult. Energy used in respiration were estimated to be 48.48 cal in females and 36.45 cal in males from juvenile to adult. The energy intakes from feeding were 84.15 cal in females and 67.09 cal in males from juvenile to adult. Energy losses by excretion were 10.36 cal in females and 6.46 cal in males. Thus, females assimilated 86.65% and males 81.99% of assimilated energy in somatic growth. The gross growth efficiencies (k1) showed 8.71% for females and 9.02% for males and the net growth efficiencies (k2) showed 10.05% for females and 12.36% for males. Maintenance costs were estimated at 66.48% of assimilated energy in females and 66.26% in males. Molting losses among the energy assimilated from juvenile to adult were estimated to be 0.63% in males and 0.69% in females.

This study was conducted to assess the recognition and consumption of health functional food (HFF) of the college students in the Northern Gyeonggi-do area (Republic of Korea). To accomplish this, a survey was conducted to investigate 360 college students (183 males and 177 females) regarding their general characteristics, as well as the recognition, knowledge, considerations, purchases and consumption of HFF. Most male and female students (68.9% and 61.6%, respectively) were unaware of the HFF certification mark, however, more females(58.8%) were aware of the legal HFF definition compared to males (36.6%). The HFF advertising routes for males and females were 'TV radio' (43.2% and 43.5%, respectively) and 'internet smart phones' (19.7% and 27.1%, respectively). The main factor considered for selection and the most serious problem concerning HFF by males and females were 'effectiveness' (36.1% and 43.6%, respectively) and 'hype (exaggerated advertisement)' (35.0% and 55.9%, respectively). The main purchase route by males and females was 'pharmacy' (35.2% and 27.8%, respectively). The main reason for HFF product purchase by males and females was 'health promotion' (38.8% and 29.4%, respectively) and the main reason for not purchasing an HFF product was 'no health problem'(34.8% and 36.7%, respectively). The percentage of HFF consumption was 46.0% in males and 69.8% in females. The main HFF product consumed by males and females was 'vitamin mineral' (36.9% and 43.5%, respectively). The main reason for HFF consumption by males was 'health promotion' (31.0%) and females was 'recovery from fatigue' (21.8%). The main reason for not consuming HFF by males and females was 'no health problem' (38.4% and 41.5%, respectively). These results suggest the need to provide correct information concerning HFF to college students. Based on these results, greater efforts should be made to provide meaningful information regarding factors affecting purchase and consumption patterns for college students related to the research and development of HFF in the Northern Gyeonggi-do area.

The purpose of this study was to investigate the effects of gender on the thermic effect of food and substrate oxidation rate during 5 hours after a mixed meal. Twenty healthy college students (10 males and 10 females) aged 20-26 years participated in this study. The energy contents of the experimental diets were 775 kcal and 627 kcal for males and females respectively, which were 30% of individual energy requirements and were composed of 65/15/20% as the proportion of carbohydrate/protein/fat. Resting and postprandial energy expenditure and substrate oxidation rates were measured with indirect calorimetry in the fasting state and every 30 min for 5 hours after meal consumption. Thermic effects of food expressed as ${\Delta}AUC$ and TEF% were not significantly different between males and females. However, TEF% adjusted for body weight and fat-free mass in males (0.095% and 0.120%) were significantly lower than those in females (0.152% and 0.213%)(p < 0.05). The total amount of carbohydrate oxidized was significantly lower in males than that in females (58.6 vs. 86.6 mg/kcal energy intake/5 h, p < 0.05). In contrast, the total amount of fat oxidized was significantly higher in males than that in females after the meal (32.9 vs. 17.2 mg/kcal energy intake/5 h, p < 0.01). These results indicate that gender affects the thermic effects of food and the substrate oxidation rate after a meal. The results show that males use relatively less carbohydrate and more fat as an energy source after a meal than that of females.

This study was performed to assess the nutritional status, frequency of visiting and necessity of nutrition programs for 157 elderly(male:49, female:108) visiting public health centers in Puchon. The purpose of the study was to provide the basic data for developing a nutrition service model. The subject were investigated by interviews with a questionnaire to obtain dietary data and other information related to public health center. Blood tests for analyzing biochemical status were also carried out. The elderly showed low income status. Ninety two percent of them showed their monthly income was less than 400,000 won and 72.6% was observed as having 30,000 won/month as their pocket money. The most frequent disease reported as having or being treated were hypertension(32.6%), rheumatic arthritis(28.5%), diabetes(10.2%), and stomach disease(8.2%) for males and hypertension(33.1%), diabetes(19.4%), rheumatic arthritis(16.7%), anemia(11.1%) for females. The nutrients whose daily intakes were less than 2/3 of RDA were calcium(37.5% RDA),vitamin A(49.9% RDA), iron(60.0% of RDA) and protein(62.0% RDA) for males and vitamin A(27.7% RDA), vitamin B$_2$(33.3% RDA), calcium(44.1% RDA), iron(53.3% RDA), and niacin(60.0% RDA) for females, respectively. Prevalence of anemia, assessed by hemogloben using WHO definition, were 4.1% for males and 18.5% for females. The percentage of males with hypercholesterolemia( 220 mg/dl) was 2.1% and 19.4% fir females, Two percent of males and 12.0% of females were observed as having a LDL-C higher than 165 mg/dl. The mean fasting blood glucose(FBG) level of males and female was 84.2 mg/dl and 101.7 mg/dl respectively. Two percent of males and 8.3% of females were found with a FBG higher than 140 mg/dl. Seventy one percent of elderly reported they were visiting public health centers at least once per week or more frequently. They were satisfied most with the low medical bills but showed the lowest satisfaction for the facilities of the public health centers. What the nutrition service programs wanted most was nutrition counseling and guidance.
