The purpose of this study was to determine the preference and purchasing intention on necktie pattern designs according to male consumers' fashion lift style. Written questionnaires were handed out to 300 male consumers of the 20-40 years old in Seoul and surroundings, who were accessed by a convenience sampling method. The questionnaires were to classify male consumer groups according to the fashion life style, to examine characteristics, needs and wants of each group. The stimuli of 8 kinds of necktie patterns in black & white, and the semantic differential scale were applied to evaluate the preference and purchasing intention on necktie pattern design. A total of 265 samples were analyzed by factor analysis, cluster analysis, ANOVA, crosstabs and $X^2$-test through SPSS package program. Six factors in their fashion life style were extracted as follows: those were 'fashion-oriented', 'traditional conservative', 'brand-flaunting', 'personality-oriented', 'practicality-oriented' and 'unconcerned' life style. With these life style sub-dimensions, male consumers were segmented into five groups: these groups were 'strong personal seekers', 'practical brand seekers', 'traditional personal seekers', 'active fashion seekers', 'unconcerned group'. Each of these groups of male consumers showed significant differences in the preference and purchasing Intension of necktie pattern designs according to their fashion life style.

The purpose of study was to analyze secreted nectar volume, nectar sugar content and amino acid in addition to estimating honey quantities that can ultimately reap in male and female flowers of Evodia daniellii Hemsl.. The maximum blooming period of male flowers was on 24 to 26 July in 2012. On average, nectar volume secreted by nectary was $2.73{\pm}0.73{\mu}L$ from one male flower and nectar concentration showed 17.4%. The maximum blooming period of female flowers was on 7 to 9 August in 2012. Nectar volume secreted by nectary was $0.63{\pm}0.49{\mu}L$ from one female flower and nectar concentration showed 25.7%, averagely. As results of correlation analysis between the meteorological factors and nectar characteristics, we found that nectar quantities and concentration were influenced by temperature and relative humidity. Sugar content was calculated at $48.0{\pm}5.2{\mu}g$ per a male flower and $37.8{\pm}8.7{\mu}g$ per a female flower, which meant that both values were not significantly different (Mann-Whitney's U-test, p=0.400). The minimum estimates of honey harvest for a male and female inflorescence were 67.8 g and 53.5 g, respectively. Analysis of amino acid showed that Serine, Glycine and Alanine were more abundant in male flowers, however Asparatate, Glutamate, Asparagine and Glutamine were more abundant in female flowers.

Clonorchiasis sinensis is the most important endemic disease in In Korea, and this disease has been known to be one of public health concern in mary areas of southern part of Korea. This survey was undertaken to evaluate the status of clonorchiasis in Eui-Seong Gun, Kyungpook Province from March 1974 to August 1974. A total number of 3,771(male 2,037. female 1,734) consisting of 2,948 primary school children, 774 middle school students, 49 high school students were examined by the intradermal test with clonorchis antigen. In order to detect clonorchis egg, the stool examinations were undertaken on the residents in Bong Yang Myun. And, the intensity of the clonorchis infection was estimated by the Stoll's egg count. The following results were obtained in this survey; 1. As a whole, 6.0 per cent of the examiners showed positive reaction by the intradermal test (male 8.0%, female 3.6%). 2. Among 249 residents in Bong Yang Myun, the prevalence rate of clonorchis eggs was shown as 45.8 per cent. 3. The mean E. P. G. in Bong Yang Myun 114 inhabitants was 2,197. 4. The degree of the intensity of clonorchis infection by E. P. G. counts was distributed to the light (50.9%) medium (43.9%) and heavy infection groups(5.3%).

Objectives: It has been known that the contents of dreams change according to neuro-developmental differences in sex, progression of age and various environments, unlike the established psychoanalytic theory. To investigate the changes, we collected "most recent dream report" and analyzed the contents of dreams by using Hall/Van de Castle System. Method: Most recent dream reports were gathered from age 12-14 years old, 2,673 middle school students (1,544 male 1,129 female) and analyzed those reports using Hall/Van de Castle System. The data were sorted in SAS and dream SAT. Result: There were prominent differences between male and female middle school students in Male/Female Percentage (male/ female；56%/35%), Familiarity Percentage (57%/69%), Aggression/Friendliness Percentage (79%/65%), Befriender Percentage (50%/33%), Physical Aggression Percentage (90%/70%), Indoor Setting Percentage (40%/55%), Negative Emotion Percentage (56%/68%) and Torso/Anatomy Percentage (51%/36%). There were significant differences in Male/Female Percentage (65%/44%), Friendliness, Physical Aggression and Self Negativity Percentage in male and there were significant differences in Friendliness, Familiarity and Friends Percent in female between 1st and 2nd grade. But, it showed much similar dream patterns between 2nd and 3rd grade in both gender. In male, Aggression/Character Index with male character is significantly increased by 2nd grade (1st/ 2nd/ 3rd；0.48/ 1.04/0.98), In female, Friendliness/Character Index with male character had significantly decreased by 2nd grade (0.38/ 0.19/0.20). Conclusion: There were apparent differences between age 12-14 years old male and female. Male adolescents have differences mostly in categories related with aggression, but female adolescents have differences in categories related with environment or character. It shows that developmental level of male are slower than female as of yet and male needs more active interpersonal relationship to find identity. Otherwise, the influences of passive attitude and actual circumferential environment are reflected in female's dream. There are no prominent differences among ages, but age 12-13 years old adolescents shows significant differences in interacting with the other gender. It means that circumferential environment and interpersonal relationship affect the contents of dreams and also the cognitive development related to age and sex. Afterwards, the development of dreams could be better understood through the neurocognitive study and dream analysis between other ages and nations.

Objectives: Osteoporosis is the most common metabolic disease of the bone, and is one of the most important major public health problems world wide. It is more occurred in female than male, but as the osteoporosis of men is increasing, therefore bone fractures of men are increasing. So we investigated the factors which are related to Bone Mineral Density(BMD) of male for prevention of osteoporosis. Methods: We measured the Bone Mineral Density(BMD) of lumbar spine($L_2$-$L_4$) and femoral neck in 5198 male, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha). And then we analysed the 8 factors - age group, bone mass index(BMI), amount of smoking, drinking, exercise, and fast blood sugar, gastric disease, thyroid disease - which are related to BMD of male. Results: 1. In age group according to ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$, T-score was the highest at 17-24(三八歲) years group and decreased rapidly after 57-64(八八歲) years group in both lumbar spine($L_2$-$L_4$) and femoral neck. Therefore we concluded that T-score of male in lumbar spine($L_2$-$L_4$) and femoral neck change according to age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$. 2. In BMI(body mass index), T-score of lumbar spine($L_2$-$L_4$) and femoral neck were the highest in obese group than non-obese group. In comparison of age group according to BMI, T-score of lumbar spine($L_2$-$L_4$) was significant difference in 17-72 years group and T-score of femoral neck was in 25-72 years group. 3. In exercise, T-score of lumbar spine($L_2$-$L_4$) and femoral neck was increasing as exercising more. In comparison of age group according to exercise, Both T -score of lumbar spine and femoral neck were significant difference in 25-72 years old. 4. T-score of lumbar spine($L_2$-$L_4$) was the highest in men who have taken exercise daily, and T-score of femoral neck was the highest in men who have taken exercise 1-3 times for a week. Conclusions : The age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$ is related to BMD of men. And risk factors - BMI, exercise - are related to BMD of men. Therefore we expect that this study will help for prevention of osteoporosis of men.

Dimethylamine (DMA) is a widely used commodity chemical with few toxicity data. Groups of 10 male and female F-344 rats were exposed by inhalation to 0, 5, 10, 20, 40 and 80 ppm of DMA for 6 hrs/day, 5 days/week for 90 days. The changes of body weight, organ weight, hematology, clinical chemistry, and histopathological changes were evaluated after the exposure. As the results, the body weight was significantly decreased at 80 ppm in male and female rats (p<0.05). The absolute lung weight showed no statistically significant changes in any group. In contrast, the relative lung weight significantly increased at 80 ppm in male and female rats (p<0.05). Erythrocytes, mean cell hemoglobin, leukocytes, neutrophil, and platelet numbers were significantly increased in male and female at 40 or 80 ppm of DMA (p<0.05, p<0.01). In addition, the serum values of total protein, urea nitrogen were increased in male and creatine kinase, total protein were increased in female rats at 40 or 80 ppm (p<0.05, p<0.01). Histopathological examinations of the male and female lung samples showed slight hyperplasia and congestion at 80 ppm. Taken together, our study revealed that maximum tolerated dose of DMA would be over 40 ppm.

The effects of the vegetable diet on the levels of the serum lipids, particularly the level of the serum total cholesterol which is most concerned with coronary heart disease (CHD) were investigated in 30 male SDA (Seventh Day Adventists) group and 30 male omnivorous group (control group). SDA participated in this study intaked relatively few animal origin foods whereas they intaked plant origin foods largely; they seldom or sometimes intaked meats, fishes, butter, margarine, beverages and coffee, but often unrefined cereals, legumes, vegetables and fruits. In the both systolic pressure and diastolic pressure, there was no difference between two groups. The levels of the serum total cholesterol, triglyceride and phospholipid were lower in SDA group than in the omnivorous group. Among them the difference was statistically significant in the level of the serum total cholesterol. HDL-cholesterol was more or less higher in SDA group than in the omnivorous group, but the difference was no significant. The result that SDA group had lower level of the serum total cholesterol than the omnivorous group suggested that that they might be less prone to CHD than the omnivorous group. Though this possibility, however, was derived from the fact of the lower level of serum total cholesterol of SDA group, it might by partly responsible for their habit that they never smoke and drink alcohols and coffee.

Males of the field cricket Teleogryllus emma produce calling songs that are attractive to receptive females. The calling songs of T. emma consist of two components, the long chirp that is composed of up to 12 single pulses, followed by a variable number of short chirps. Based on the analysis of coefficient of variation (CV), temporal characters of the long chirp were less variable than those of the short chirps in male calling songs. To test for phonotactic selectivity of females, we conducted a single-stimulus playback experiment in which five stimuli (standard, long chirp only, long chirp augmented, short chirps only, and short chirps augmented) were used. The standard stimulus included both long and short chirps whose characteristics were derived from the calling songs of field populations. Results of the playback experiment showed that female crickets oriented more frequently toward the stimuli that included the long chirp (standard, long chirp only, and long chirp augmented stimuli) than toward the stimuli lacking the long chirp (short chirps only and short chirps augmented stimuli), indicating that the long chirp in the calling songs was required to elicit positive phonotaxis in the female crickets. The result of CV analysis of the male calling songs and the findings of the female phonotaxis experiment suggested that the long chirp of calling songs may play a role in species recognition in T. emma.
