We monitored a breeding population of the Asian toad (Bufo gargarizans), in the Wonheunge pond at Sannamdong, Chungju, from 5 March to 11 April, 2006 and 14 February to 31 March, 2007 to investigate their movement patterns, breeding population sizes, and physical characteristics. Terrestrial migration to the pond started on 5 March in 2006 and 14 February in 2007. We captured a total of 266 immigrating individuals (213 males, 53 females) in 2006 and 307 (222 males, 85 females) in 2007, and found 50 adults apparently killed by motor vehicles while migrating to the pond in 2007. Emigration from the pond to terrestrial sites started on 15 March 2006 and 5 March 2007. We captured a total of 245 emigrating toads (181 males, 65 females) in 2006 and 99 (92 males, 7 females) in 2007. An additional 10 emigrating adults were found dead on the road. During both the immigration and emigration periods, two peaks in capture frequency appeared for each sex in each breeding season. The immigration peaks corresponded with higher temperatures, while the emigration peaks corresponded with high humidity. Migrating Asian toads showed sexual size dimorphism and a male-biased sex ratio. Body weights and SVL (snout-vent length) of immigrating and emigrating individuals were negatively related with migration dates.

Based on the fact that a parody is widely used as one of main methods of creating art, this study focuses on the parodic techniques used by one of the most famous contemporary artists, Cindy Sherman. Her unique techniques, which are shown through parody, provide different aesthetical values to contemporary fashion designs. The purpose of this study is to find out whether or not contemporary fashion designs that use parodies can be presented as creative fashion designs. The study was carried out by analyzing data retrieved from various literatures, dissertations, magazines and the Internet. The period between the late 1990s and 2010 is the time when parodies were widely introduced, this study presents tables, pictures and photographs based on data collected from that period. The result of this study suggests that there are mainly four expressive techniques used to create Cindy Sherman's parodies: female viewed from a male's perspective, pornography and sexual satire, narrative and realistic reproductions, and foreignness and harmony in conflict. This study discovered that based on these four expressive techniques, contemporary fashion can produce the following four results according to their production styles, silhouettes, materials, and colors: the beauty of the retro pinup girl style, the beauty of eroticism and sexual satire, the beauty of history through reinterpretation of the past, and the beauty of compromise through conflict. As described above, this study attempts to seek how techniques of parodies give different aesthetical values whether or not they can become creative fashion design techniques by listing Cindy Sherman's unique expressive techniques in her parodies in relation to contemporary fashion designs.

Structure on the feeding organs in two Korean ricefishes, Oryzias latipes and O. sinensis, was examined in the jaws and the teeth. In the jaw, O. latipes has a dent on the dorsal edge of distal arm of premaxilla (vs. straight in O. sinensis) and a alveolar arm of premaxilla running in straight line with distal arm of premaxilla (vs. ventra line in O. sinensis). O. latipes has also a dent on the posterior edge of dentary which is connected to coronoid process of dentary (vs. straight in O. sinensis). Large teeth developing only in the male, which is sexual dimorphism, developed into outside direction of the mandible in O. latipes (vs. dorsal direction in O. sinensis). In the teeth forms, O. latipes has two types (conical type and arrowhead type), whereas O. sinensis has only one type (conical type). Through this study, we confirmed that two Korean ricefishes show distinctive characteristics in the structure of the feeding organs.

Despite the growing popularity of gay consumers as a fetching niche market, there has been little academic attention paid to the homosexual themes in print media, especially compared to research on gender, race, and sex imagery in ads. The present study aims to fill this void by examining advertisements with three different target audiences(homosexual, metrosexual, retrosexual consumer) through a comparative analysis of contemporary magazine advertisements. In this present study, we analyzed ads in three leading men's magazines (Out, GQ, and Maxim). Product (product category, price, and luxury brand) and human model (basic descriptions, sexuality, status, and masculinity) characteristics in ads were analyzed as the variables signifying the degrees of gay themes in ads across three magazines. The results showed that more expensive luxury brands were placed in GQ and Out than Maxim, and more male models were under-sexualized in Maxim than GQ and Out.

This article investigates 295 social workers in order to find out how much they believe that each behavior related to dual relationships is ethical and with how many clients they engaged in these behaviors. This article, based on the literature, explores three areas of dual relationships which are sexual, bartering, and private dual relationships. The results from the research were 1) The social workers tend to believe that while sexual and bartering dual relationships are less ethical, private dual relationships are more ethical. Meanwhile, they have little experience to engage in all areas of dual relationships; 2) Compared to beliefs and experiences, the social workers believe that each behavior is ethical, but they have less experienced the same behavior. However, the result of strong correlations between beliefs and experiences shows that the more the social workers believe that the behaviors are ethical, the more they tend to engage in the behaviors; 3) Based on socio-demographic characteristics, male social workers tend to accept dual relationships as ethical behavior than their female counterparts do. And those who are practicing in health settings tend to believe that the behaviors related to dual relationships are less ethical than those who are practicing in the other areas of the profession do. Finally, the research recommends that enhancing social worker's self-awareness and professional maturity is needed in order to prevent the occurrence of dual relationship engagement. Also, social work professional associations and agencies should provide education, training, and institutional restrictive devices for dealing with unethical dual relationships.

Rider jackets were once reserved for military uniforms but have become an important styling item in recent fashion trends. The design characteristics of the rider jacket are rooted in symbolism, and the image associated with a rider jacket is in line with the challenging of authority and being a member of the rebellious youth subculture. Usually, young people with anti-social tendencies wore jackets, and some styles were used as a medium to express their emotional homogeneity, and they received favorable responses as the items represented them. The design characteristics of a rider jacket can be largely divided into resistance against the older generation, violence, challenging cultural norms, sexuality, and resistance, as well as embodying violent characteristics, including strength, courage. and male chauvinism. The reason for the development of these challenging characteristics are disparagement and anger of the lower class, who were excluded from mainstream society. Rider jackets can be viewed negatively due to the kind of message it is conveying against mainstream society. Among the sexual features were leather pants, short-length leather rider jackets, glossy metal accessories, and belt buckles, which also highlighted gay and decadent images that came to be associated with the jackets. The drapery created various kinds of wrinkles according to the way of dressing, and it had beautiful expressiveness while serving to express the body more beautifully. Drapery can be classified according to the aesthetic characteristics or expression techniques, and if the type of drapery is classified according to the morphological characteristics, it can be classified into variable and fixed structures, depending on whether the part to which the drapery is applied is fluid or not. In other words, it depends on the dressing method or the intention, and if the drapery technique is directly applied to the garment or is attached to the form. This fashion design proposal may have the greatest significance in that it sought to propose a new style incorporating a drapery technique with a strong feminine image to a rider jacket, which traditionally was associated with a masculine image.

The purpose of this study is to comprehend the contemporary sports star fashion and to contemplate aesthetic characteristics of sports star fashion, thereby to establish the styles of sports star fashion. For such purposes, this study first examines aesthetic characteristics of sports fashion and star fashion based on previous studies, in order to analyze aesthetic characteristics of sports star fashion, and conducts a case study by analyzing photographic materials of fashion styles of well-known male sports stars such as the English soccer player David Beckham and American golf player Tiger Woods. The result of this study is as follows: the aesthetic characteristics of the contemporary sports star fashion are virility, functionality, sensuality and deconstruction. (1) Virility emphasizes manly features by displaying trained and disciplined body. (2) Functionality is expressed through structural simplicity and temperance of decoration. High-tech textiles and fibers are favored in order to fit in comfortable bodily movement for the heavy exercises. (3) Sensuality, as an expression of indulgence of sexual pleasure, is expressed through bodily exposure. Lastly, (4) deconstruction, which means destroying existed boundaries of cultural categories, is shown as co-existence of design elements from different times and places, stereotypes and sensibilities. Virility and functionality are prominent characteristics expressed in sports uniforms and training costumes. Sensuality and deconstruction are shown in daily fashion and formal dress outside the sports field.

Nonylphenol (NP) is an estrogen-mimicking compound or xenoestrogen. This study investigated the effects of nonylphenol on the reproductive status of the equilateral venus Gomphina veneriformis. The experiment lasted 24 weeks, Experimental groups consisted of a control and three nonylphenol exposures ($1.0,\;2.5,\;and\;5.0\;{\mu}g\;NP/L$). Mortality did not differ significantly between the control and the exposure groups. The sex ratio (F:M) was 1:1 in nature and 1:1.03 in the control group. However, it changed to 1:3.5 with $5.0\;{\mu}g\;NP/L$ exposure. Gonad maturity in females was higher in the nonylphenol exposure groups than in the control group. By contrast, in males, it was lower in the nonylphenol exposure groups. Intersex individuals constituted 0% in nature, 3.08% in the control group, and 23.6% in the group exposed to nonylphenol, with female characteristics more prevalent than male. As the concentration of nonylphenol increased, the accumulation of lipofuscin increased in the mid-gut gland.

In chicken, exogenous genes introduced into germinal crescent region (GCR) of the early developmental stage, where primordial germ cells (PGCs) were concentrated, were successfully transferred to the gonads via PGCs. The foreign genes were also confirmed to be successfully incorporated into F1 and F2 generations. We tried to incorporate the exogenous genes into PGCs by lipofection, then the DNA mixture was injected into GCR at stage 3-5 or 9-11 of embryonic development (Hamburger and Hamilton, 1951). The manipulated eggs were incubated, and hatched chicks were reared until sexual maturation. F1 generation was obtained from the DNA-treated chicken (DNA-chicken) mated with normal birds. Furthermore, F2 generation was also obtained from the F1 chicken mated with normal birds. The transfer of introduced foreign genes were confirmed by marker gene detection methods and PCR analysis in the hatched chicks, F1 and F2 generations. However, in our experiments, DNA-chickens showed abnormal characteristics such as low egg production rate, abnormal appearance and decreased number of spermatozoa. In the case of F1 chicken, low egg production and the deterioration of sperm capacity for insemination in male chicken were observed.

The purpose of this study was to analyze the classification and meaning of symbols, of the clothes of the college students by sex-roll theory and identity theory. The clothes analyzed in this study were collected by photographs which were taken in the campus (240 out of 1,000 pictures) of the several colleges and universities in Seoul form fall in 1993 to summer in 1994. The results were as follow : 1. Analysis as a symbol of sexuality. The phenomenon of the visual inconsistency and consistency of sexual image in dress were showed simultaneously. The clothes of male students were generally becoming feminine style in materials and colors of clothes. These suggested that sex-roll theory be applied to their clothes. 2. Analysis as symbols of identification or individuality. The identification of shoes, bags, accessories, and hair styles were prominent than that of clothes. When it was analyzed as a symbol of individuality, the college students seemed to act as fashion leaders, who accepted new fashions and tried them on first. These suggested that Erikson′s theory on identity be applied to their clothes. 3. Analysis as a symbol of emblem. The dissimilarities of between the college students and other groups in the same generation were bright and casual attire with files, books, and sack. 4. Analysis as a symbol of campus ceremony. The clothes of college students on campus ceremonies were more causal and flexible than those of other groups in the same generation. It was known that the symbols showed above were reflected on their clothes as "one′s expressions" which are sex-roll, identity, and characteristics of college students.
