The purpose of this study was to classify types in sense of gender role identity and to figure out the difference among sociocultural attitude, benefits of clothing pursuit, and appearance management behaviors by sense of gender role identity types. Questionnaires were administered to 455 people in their twenties and thirties living in Daegu and Kyoungbuk area. Data were analyzed by using frequency, factor analysis, credibility, $X^2$-test, ANOVA, Duncan-test, and t-test. The findings are as follows. First, Men of androgyny group showed the highest rate of 38.5% followed by undifferentiation(22.9%), masculineness(21.0%), and feminineness(17.6%). Women of undifferentiation group showed the highest rate of 33.2% followed by feminineness (25.2%), androgyny(22.0%), and masculineness(19.6%). Second, factors of sociocultural attitude were internalization and recognition. Benefits of clothing pursuit consists of the factors such as consciousness of others, personality, and vogue pursuit. Factors of appearance management behaviors were dressing, skin management, plastic surgery management, weight management, health management, and hair management. Third, the result from the difference between sociocultural attitude and benefits of clothing pursuit by sense of gender role identity types, men of androgyny and feminineness showed highest in recognition while women of androgyny showed highest in internalization and recognition. The result of the difference in benefits of clothing pursuit by sense of gender role identity shows that both men and women of androgyny group have high tendency for being conscious of others, personality pursuit, and vogue pursuit while men of undifferentiation and masculineness have low interest in dressing in relationship with others. Fourth, the examination of the difference in appearance management behavior by sense of gender role identity types found men of androgyny group managed dressing, skin, weight, health and hair most while women dress and health most. Men of undifferentiation group managed dressing and weight least, while men of masculineness health, and men of feminineness hair least.

This article explores bilateralization phenomena in Korean families through intimacy and interaction with matrilineal kins. In-depth interviews were conducted with married men and women aged from their mid-30s to mid-40s. The findings indicate that the intimacy range of participants was restricted to blood-based kins. The power hypothesis was supported for male participants. Some wanted to actively contact their spouse's family members, while others did not want to be connected with the spouse's families. Interaction with wives' families was based on the exchange perspective. In contrast, a complicated mechanism existed in the intimacy and interaction of female participants. Most of them were connected with in-laws in a passive way but actively interacted with their family-of-origin. However, some female respondents did not have good relationships with their mothers. Undifferentiation between mothers and married daughters negatively influenced their relationships. Therefore, it could be concluded that bilateralization phenomena in Korean families is another kind of shackle of patrilineal norms.

The purpose of this study was to classify sex role identity into groups and analyze the difference of social face sensitivity and appearance management behaviors by sex role identity. Questionnaires were administered to 306 people in their twenties and thirties living in Daegu Metropolitan City and Kyoungbuk province. The data was analyzed by using frequency, factor analysis, credibility, ${\chi}^2$-test, ANOVA, Duncan-test, and t-test. The findings were as follows. Sex role identity were classified into four groups (androgyny, masculineness, feminineness, and undifferentiation). Men in androgyny group showed the highest rate of 41.3% followed by undifferentiation(24.7%), masculineness(21.3%), and feminineness(12.7%). Women in undifferentiation group showed the highest rate of 35.9% followed by feminineness(24.4%), androgyny(23.7%), and masculineness(16.0%). Social face sensitivity were composed of four factors (consciousness of being embarrassed, social formality, other consciousness, and prestige). Appearance management behaviors were composed of six factors (skin management, fashion image management, plastic surgery management, weight management, hair management, and health management). According to the result of a significant difference between social face sensitivity and appearance management behaviors by sex role identity, male showed significant difference between the sub-variables of social face sensitivity factors (consciousness of being embarrassed, social formality, and other consciousness). Both of the male and female showed a significance of difference in consciousness of being embarrassed, and social formality. Male showed significant difference between the sub-variables of appearance management behaviors factors (fashion image management, weight management, hair management, and health management). Both of the male and female showed a significance of difference in fashion image management. Gender of twenties and thirties showed distinction between the sub-variables of social face sensitivity factors (consciousness of being embarrassed, and prestige) and appearance management behaviors (skin management, fashion image management, plastic surgery management, weight management, and hair management).

Despite many researches related with in-vitro culture of porcine spematogonial stem cells (SSCs), adherent culture system widely used has shown a limitation in the maintenance of porcine SSC self-renewal. Therefore, in order to overcome this obstacle, suspension culture, which is known to have numerous advantage over adherent culture, was applied to the culture of porcine SSCs. Porcine SSCs retrieved from neonatal testes were suspension-cultured for 5 days or 20 days, and characteristics of suspension-cultured porcine SSCs including proliferation, alkaline phosphatase (AP) activity, and self-renewal-specific gene expression were investigated and compared with those of adherent-cultured porcine SSCs. As the results, the suspension-cultured porcine SSCs showed entirely non-proliferative and significantly higher rate of AP-positive cells and expression of self-renewal-specific genes than the adherent-cultured porcine SSCs. In addition, long-term culture of porcine SSCs in suspension condition induced significant decrease in the yield of AP staining-positive cells on post-day 10 of culture. These results showed that suspension culture was inappropriate to culture porcine SSCs, because the culture of porcine SSCs in suspension condition didn't stimulate proliferation and maintain AP activity of porcine SSCs, regardless of culture periods.

The purpose of this study as a research of experience of sexual offenders who are in confinement in prisons and forensic facilities is to theoretically investigate fundamental structures of their experiences and to practically construct basic data to present intervention programs of sexual offenders. This study was conducted by hermeneutical and phenomenological methods invoked of the analytic framework of Van-Manen (1990) about seven sexual offenders. The data were collected through in-depth interviews, and the results of the interpretation are shown as perception that they were victims of public opinion, the mark of Cain, loss of opportunity of examination caused by show window, collective differentiation through distinction, expression of metaphysical being that wants to slip out of the skin, counterplot of scientific management techniques, undifferentiation from the Imaginary, sexual acts shown as inverted communication, discovering dominant domain as forming reaction to being controlled, not being free from capitalistic attributes in which even children's sex is commercialized, distortion in socialization of sexual identity, paternity stamped as embodiment of suppressed desire, recovery of lost virginity of mother through children, and family as a name broken to pieces.

Objective: Human embryonic stem cells (hESCs) can proliferate indefinitely and differentiate into all kinds of cell types in vitro. Therefore, hESCs can be used as a cell source for cell-based therapy. Transduction of foreign genes to hESCs could be useful for tracing differentiation processes of hESCs and elucidation of gene function. Thus, we tried to introduce enhanced green fluorescent protein (eGFP) gene to hESCs, XX and XY cell lines in this study. Methods: Lentivirus containing eGFP was packaged in 293T cells and applied to hESCs to transduce eGFP. Expression of transduced eGFP was evaluated under the fluorescence microscope and eGFP positive population was analyzed by FACS. Expression of undifferentiation state markers such as Oct4, Nanog, SSEA4 and Tra-1-81 was examined by RT-PCR and/or immunofluorescence in eGFP-hESCs after transduction. In addition, the ability of eGFP-hESCs to form embryoid bodies (EBs) was tested. Results: eGFP was successfully transduced to hESCs by lentivirus. eGFP expression was stably maintained up to more than 40 passages. eGFP-hESCs retained expression patterns of undifferentiation state markers after transduction. Interestingly, disappearance of transduced eGFP was notably observed during spontaneous differentiation of eGFP-hESCs. Conclusion: We established eGFP expressing hESC lines using lentivirus and showed the maintenance of undifferentiation characteristics of these eGFP-hESCs. This reporter-containing hESCs could be useful for tracing the processes of differentiation of hESCs and other studies.

Objective: This study was performed to evaluate the possibility of prolonged culture of human embryonic stem cells (hESC; SNUhES2) on human amniotic fluid cells (hAFC), which had been storaged after karyotyping. Method: The hAFC was prepared for feeder layer in the presence of Chang's medium and STO medium (90% DMEM, 10% FBS) at $37^{circ}C$ in a 5% $CO_2$ in air atmosphere. Prior to use as a feeder layer, hAFC was mitotically inactivated by mitomycin C. The hESCs on hAFC were passaged mechanically every seven days with ES culture medium (80% DMEM/F12, 20% SR, bFGF). Results: The hAFC feeder layer support the growth of undifferentiated state of SNUhES2 for at least 59 passages thus far. SNUhES2 colonies on hAFC feeder appeared slightly angular and flatter shape as compared with circular and thicker colonies observed with STO feeder layer and showed higher level with complete undifferentiation in seven days. Like hESC cultured on STO feeders, SNUhES2 grown on hAFC expressed normal karyotype, positive for alkaline phosphatase activity, high telomerase activity, Oct-4, SSEA-3, SSEA-4, Tra-1-60 and Tra-1-81 and formed embryoid bodies (EBs). Conclusion: The hAFC supports undifferentiated growth of hESC. Therefore, these results may help to provide a clinically practicable method for expansion of hESC for cell therapies.

The purpose of this study is to classify men in their 20s by their sex role attitudes, and to study their appearance management behavior and inner characteristic variables such as socio-cultural attitudes on appearance and bodily image, which are expected to influence the appearance management behavior of each classified group. For this, a survey of 393 males in the 20s in Seoul and metropolitan areas was conducted. Factor analysis, Cronbach's alpha coefficient, and F-test were conducted on the data. First, as a result of analysis on sex role attitudes, four groups were categorized: Masculinity, Femininity, Androgyny and Undifferentiation. Second, the analysis of individual variables resulted in appearance management behavior being separated into five categories: Interests in fashion, Proper choice of clothing, Importance of bodily attractiveness, Pursuit for personality and Complementation of physical weaknesses. The socio-cultural attitude on 'appearance' was sub-categorized into Internalization, and Awareness, while 'body image' was divided into Cognitive behavioral and Affective aspects. Regarding differences in socio-cultural attitudes for appearance, body image and metro-sexual lifestyle attitudes, the androgyny group produced the highest scores. Based on these results, it can be concluded that people who take care of their physical appearance, cope effectively with social and circumstantial requirements for happiness and success, and respond flexibly and affirmatively.

The purposes of the study were to find the characteristics of spousal conflict, the characteristics of the origin of family in couple, the intervention techniques of the family therapist, and the processes of change in couple through family therapy. The total family counseling was 9 sessions, which included individual and couple therapy. The study used constant comparative analysis by using open coding method to find the factors. The study suggested the whole model for the study, which could be shown the processes of family therapy in this case study, by using graphical network display. The results of study showed the personal characteristics of husband and wife, the characteristics of the origin of family in couple, the intervention techniques of the family therapist, and the processes of change in husband through family therapy by using matrix. The results revealed that there were many differences in characteristics to cause spousal conflicts and characteriscts in family of origin to influence the crisis of divorce. The therapeutic intervention to treat the couples in the crisis of divorce were facilitation of communication between husband and wife, husband's differentiation of self from family of origin, and understanding about the perspectives of family members. As results of therapeutic intervention, there were showed the spousal change of recognition to each other, husband's differentiation of self, wife's growth of self, and improvement of communication.
