Viability, early growth and sex ratio of induced gynogenetic diploid bagrid catfish (Leiocassis ussuriensis, Siluriformes) were examined. Survival rates of gynogenetic diploids and normal bi-parental diploids up to 180 days post hatching were not significantly different (P>0.05), and consequently resulted the mean percent survivals of 76% (gynogens) and 78% (bi-parental progeny) at the end of growth trial. Growth in both body weight and total length of gynogenetic diploids was also similar to those of normal diploid controls (P>0.05). Gynogenetic bagrid catfish displayed a similar level of ovarian development when compared to bi-parental diploid females, as judged at 10 weeks post hatching. Sex ratio of bi-parental progeny was normal 1:1 whereas all-femaleness was observed in gynogenetic progeny (P<0.05), suggesting that the genetic sex determination mechanism of this species should be XX-XY based female homogamety.

Fashion is a visual means of expressing identity, position, marital status, personal inclination, etc. along with beauty, and it is an important practical cultural heritage that can infer past lifestyle habits. In modern society, fashion such as women's suits, high heels, hats, gloves, handbags, necklaces, etc., as well as beauty such as hair, make-up and nail art. It is a model of innovative women's prize and presented a sample of femininity that responds to the radical development of science and technology in the 21st century. Therefore, it is a driving force for a genuine gender equality society. It serves as a stepping stone for futuristic future design. This study, which analyzed the factors of women's sexuality from the viewpoint of beauty college students in the fashion style of the newcomers, makes it possible to present a sample of women' s sexuality that establishes constructive self - help theory. It is thought that a solid foundation of femininity will be provided.

Natural clonal stock of triploid crucian carp, Carassius aurahs was identified and its cytogenetic, molecular genetic and morphological traits were studied. Cytogenetic analysis of the clonal crucian carp revealed that they were natural triploidy, evidenced by 1.5-fold increases of cell size, DNA content, and chromosome number. Multi-locus DNA fingerprinting using $(GATA)_4$ probe showed that they had an identical fingerprint profile, indicating the clonal propagation of the population. External morphology and morphometric characteristics of triploid individuals were much uniform compared to those of diploids. Natural triploid crucian carp was proven to be all-female in this study.

This study agrees with the idea that a situation centered perspective provides a useful contribution in understanding women's attitude on organizations. Women's occupational experiences are less related to their "femaleness" than to the structural constraints inherent in the occupational positions women fill. So characteristics of the organizational situation including gender composition and hierarchical status may "shape and define" women's experience on the job. The present study examined the managerial level's gender gap and "glass ceiling" of the corporation. According to Kanter, if the ratio of women to men in organizations begins to shift, as affirmative action and new hiring and promotion policies promised, forms of relationships and corporate culture should also change. However, the mere presence of women on workplace may not, in itself, result in women-friendly work condition. This study analyzes "Korean Women Manger Panel survey(2010 3rd. wave)" to examine how much gender gap of the managerial level persists and when the glass ceiling effect emerges. Using t-test and ANOVA, various aspects of the gender gap within managerial level were verified. The most significant finding is the glass ceiling effect starts from very low level of management. Policy implications from the statistical analysis of the Panel survey are: 1) We need to increase the absolute number of the women managers for securing middle level women leadership pipe line. 2) We need to confront the fact that the glass ceiling starts from the very low managerial level, and to explore more realistic way to break up the vicious circle for the tokenism. and 3) We need to looking beyond numbers in approaching women's matter at work. At the cultural and institutional level, work-family programs and policies, women's ratings of their competence, and family-friendly organization's climate should be considered.
