In order to study the influence of spermatozoa and testicular fluid on the component and composition of proteins in epididymal fluid of mice, histological differentiation of testis and epididymis were observed during sexual maturation, and the proteins in epididymal fluids collected according to the characteristics of lumination were analyzed by electrophoresis (SDS-PAGE). In 10 day-old mouse, both of,testis and epididymis were undifferentiated. In 20 day-old mouse, epididymis was primitively luminated, but testis was not. In 35 day-old mouse, both of testis and epididymis were luminated and eaithdymal epithelium was differentiated into principal cells and clear cells. Spermatozoa were not transfered into epididymis yet. However, in 80 day-old mouse, both of festis and epididymis were fully differentiated and spermatozoa were transfered into epididymis. In electrophoretic paftem of proteins in epididymal fluid, a total of 28 kinds of proteins were identified, which were different from those of their sera. 12 kinds out of these proteins were epididymal specific protein(ESP) detected in epididymal fluid only, and the other 16 kinds(TEP) were also detected in testicular fluid. The proteins in epididymal fluid changed during sexual maturation and 3 kinds of the proteins changed quantitatively according to epididymal regions in adult. It may be concluded from the above results that the component and composition of the proteins in epididymal fluid changed by the influx of testicular fluid including spermatozoa into epididymis and regulation of the protein synthesis, secretion and/or absorption by the epididymal epithelium. Therefore it is strongly suggested that ESP and TEP in epididymal fluid play somehow significant roles on the maturation of epididymal spermatozoa.

The purpose of this study is to investigate the subjective experiences of female college students about how they accept, resist, and interpret their gender identities and roles. The research data were autobiographic essays reflecting research participants' gender identities internalization process. Thirty essays were chosen, and carried by qualitative content analysis. It turned out that most of these female students were not blessed their birth among their family members only because of their sexes. On the one hand, these female students were restricted their behaviors by their sexes in their daily lives such as responsibility on household work, not permitting drinking, late returning home, and sexual behavior before marriage. On the other hand, they sometimes took advantage of their sexes for self-rationalization. But they were proud of the fact that they will be mothers someday. It seemed that motherhood was center for their female identity.

The primary purpose of this study is to explore the daily lives of gay men and assess their interests in fashion and appearance management with the goal of better understanding the roles or meanings of fashion in their lives. In-depth interview method was adopted and the responses were analyzed qualitatively. Six homosexual men were interviewed, and the outcome of each conversation was recorded and analyzed; each man had a different background and thus showed different behavioral patterns. The life patterns distinct to Korean gays, the importance the highly patriarchal society places on family lineage and mandatory military service, for example, were discussed. Even though the interviewees asserted that their interests in fashion is not related to their sexual orientation, fashion was utilized as a means of self-expression by these gay men.

Women's educational opportunities have been increasing and women's general advancement in higher education is the underlying factor behind the increasing number of female students in medical school. A number of issues affect female students and residents, including the existence of gender bias and sexual harassment, higher stress levels and lower levels of work satisfaction, the lack of role models in academic medicine, and conflict between work and family roles, including challenges surrounding having children. To what extent female and male medical students and residents make different career and life style choices is also an important issue. The shortage of doctors in surgical departments and maldistribution among specialties are of great concern in the health care system and medicine's future. We must prepare to solve these problems. New medical policies and educational approaches are needed for the future.

Prostate cancer is the most common malignancy among males worldwide, and is the second leading cause of cancer death among men in United States. According to GLOBOCAN (2012), an estimated 1.1 million new cases and 307,000 deaths were reported in 2012. The reasons for the increase of this disease are not known, but increasing life expectancy and modified diagnostic techniques have been suggested as causes. The established risk factors for this disease are advancing age, race, positive family history of prostate cancer and western diet (use of fat items). Several other risk factors, such as obesity, physical activity, sexual activity, smoking and occupation have been also associated with prostate cancer risk, but their roles in prostate cancer etiology remain uncertain. This mini-review aims to provide risk factors, disease knowledge, prevalence and awareness about prostate cancer.

Neo-Confucianism was the dominant ideology of the Joseon Dynasty Korea. Male and female costumes reflected a clear distinction in male and female sex roles. This study analyzes cross-dressing in sword dance performances. The research method examines relics, paintings, pictures, and documents relevant to sword dance costumes as well as for the military. The results are: First, the composition of sword dance costume was jeogori (upper garment), skirt, and shoes with military costume of jeollip (hat), jeonbok (long vest), and jeondae (belt). Second, the sword dance costume and military costume are very similar except for the basic inner wear, shoes, some details and methods of wearing. Third, the sword dance costume gradually adopted military items and features. The sword dance costume was basically female, with overall additions of a male costume, to express an androgynous image; however, the cross-dressing phenomena in the sword dance were not intended for the pursuit of sexual pleasure.

Objectives: This study investigated the association between menopausal-specific quality of life (MENQOL) and breast cancer screening beliefs among Hong Kong Chinese menopausal and postmenopausal women. Methods: A cross-sectional study was employed to collect data. The questionnaire was distributed to a convenience sample of 218 women aged above 45. The outcome variables were breast cancer screening beliefs and breast examination. Multiple regression analyses were conducted to test the effect of 4 domains in MENQOL (vasomotor, psycho-social, physical, and sexual symptom) and the health behaviors on the 2 outcome variables. Results: This study found that the overall MENQOL scores (in particular psycho-social, and physical aspects) were significantly associated with positive attitudes toward health check-ups and better knowledge and perceptions in breast cancer. Regular exercise was also significantly related to breast examination. Conclusions: MENQOL (especially psycho-social and physical domain) and regular exercise are important factors associated with breast cancer screening beliefs. The results of this study illuminate health care professionals to develop primary health care strategies to improve the quality of life of mid-life women.

This study attempted to analyze the contents of Practical Arts(Technology Home Economics)Textbooks written by the 7th national curriculum in a gender equity education. The objective of this study was to suggest some improvements which should be solved in terms of gender equity in Practical Arts, Technology and Home Economics education through analyzing their teaching and learning contents. Quantitative analysis were carried out for the objective of this study, Practical Arts(Technology Home Economics)Textbooks were divided into Technology and Home Economics fields. The pictures and illustration were analyzed in terms of sexual discrimination considering the social status and role. The analysis results were as follows. First, there were few cases of sexual discrimination in the texts. On the other hand, there were some cases of sexual discrimination in the pictures and illustration. Considering the results of some studies carried out in the 6th national curriculum, many problems raised in a gender equity education standpoint in the studies were solved. However, there were some cases of sexual discrimination which should be improved in the textbooks written by the 7th national curriculum. Second, there were few cases of sexual discrimination in Practical Arts textbooks. On the contrary many problems in terms of gender equity education were found in the textbooks of Technology and Home Economics. This result may be caused by the characteristics of Technology and Home Economics. The traditional viewpoint toward Technology and Home economics Textbook needs to be changed. In other words, their textbooks have to include practical contents for the positive sense of value and right sexual roles in terms of gender equity education. The contents of Practical Arts(Technology Home economics)Textbooks should be designed considering the articulation among the subjects and grades especially in terms of gender equity education.

In this paper we discuss the corelation be-tween feminism and fashion and examine its influnce on mordern fashion. And we also try to infer what the fashion design will be like in the future by understanding the value of modern fashion from a new viewpoint. The Early Feminism which advocated the similarity between man and women held the thought that women could be equal to men only when they behaved in the same way as men did, In 1970s when the pendulum of the Early Feminism movement reached its highest point a manish look began to flourish. The manish look introduced the items once employed only for men such as trench costs tidy tailored suits shirts and ties to women clothes. It has taken root deeply in women's life and is still employed in various ways by many designers. From the late 1970s the pendulum of feminism movement began to swing toward the Essentialist Feminism which emphasized the differences between men and women. It focused not on the negative image of women seen from male-oriented viewpoints but on their positive image and stressed women's sexual characteristic to make distinction between two genders. in fashion the Essentialist Feminism played a role in bringing about a sexy look which stressed the erotic silhouette of woman's body. The latest feminism is the socio-cultural one. It sees the distinction between men and women as sexual discrimination and introduces the androgynous human which carries the characteristic of two sexes. it leads to ambiguity of sex roles and at the same time serves to make androgynous social atmosphere by admitting the coexistence of two genders. The androgynous idea in fashion is expressed as a new trend which crosses men and women's own beauty while keeping their own identity intact. As we have briefly reviewed feminism in fashion has been presented in various ways with regard to expressing the nature of men and women. And it has continuously indicated the ultimate message of the salvation of mankind such as the respect for humanity and recovery of humanism.

Background: The IGF system plays important roles in controlling growth, development, reproduction, and aging of organisms. Methods: To estimate maturation of the Pacific oyster Crassostrea gigas, we investigated the expression of insulin-like growth factor (IGF) system components and sex-specific genes. To determine the role of the IGF system in the growth and spawning period of female and male oysters, we examined mRNA expression levels of the C. gigas insulin receptor-related receptor (CIR), IGF binding protein complex acid labile subunit (IGFBP_ALS), and molluscan insulin-related peptide (MIP), as well as those of vitellogenin (Vg) and receptor-type guanylate cyclase (Gyc76C) in gonads of C. gigas collected between April and October, when sex can be determined visually in this species. Results: We found that MIP, IGFBP_ALS, and CIR mRNA expression levels were dependent on sex and month and were greater in males than in females. CIR and Vg mRNA expression levels were very similar among females, whereas IGF system components and Gyc76C were very similarly expressed among males. The highest expression values were observed in May, when oysters are mature; CIR and Vg mRNA expression levels were highest in females, and those of MIP, IGFBP_ALS, CIR, and Gyc76C were highest in males. Interestingly, we observed a 1:1 proportion of females to males during this period. Conclusion: Our results suggest that IGF system components, as well as Vg and Gyc76C, are associated with sexual maturation in C. gigas.
