A 8-year-old male Golden Retriever dog with bilateral cryptorchidism presented for evaluation of symmetric alopecia and gynecomastia. Abdominal radiography and computed tomography revealed bilateral enlargement of the testicles in the abdominal cavity. The concentrations of estradiol and testosterone in the blood were evaluated, and the results revealed a low testosterone/estradiol ratio despite a normal concentration of estradiol. For correction, cryptorchid testicles were surgically removed. Grossly, the bilateral retroperitoneal cryptorchid testicles were enlarged, firm, and spherical. On histopathologic examination, the right abdominal cryptorchid testicle was diagnosed as a Sertoli cell tumor (SCT)-Seminoma (SEM) combination. The contralateral testicle in the abdomen was diagnosed as a Sertoli cell tumor. The clinical signs of feminization were improved after surgery. To our knowledge, this is the first report of a case of simultaneous SCT on one side and SCT-SEM combination on the other side with sex hormone profiles in a dog.

A number of chemical released into the environment eliciting their effects by disrupting normal hormonal pathways. Endocrine disrupting compounds are present in the aquatic environment and pose potential health consequences to wildlife and humans. This review are designing fur xenobiotic estrogens based on induction of the egg-yolk precursor protein vitelloge-nin. In fish of aquatic environment, it may result in decrease fertility and egg production in females or lead to reduced gonad size or feminization of genetic male fish. It has been known that male fish exposed to estrogenic compounds show induced production of vitellogenin. Vitello-genin production is normally restricted to adult females, which have elevated estrogen levels during egg production. However, vitellogenin can be induced in males by Pollution of environmental endocrine disruptors. Consequently, the presence of vitellogenin in male fish can serve as an indicator of exposure of environmental endocrine disrupting compounds. In immature fish pol-luted at low levels of environmental endocrine disrupter, vitellogenin can serve as a reliable biomarker for exposure to endocrine disrupter. This review demonstrates the utility of vitellogenin as a biomarker fur exposure to estrogenin agents in auqatic environment.

This paper investigates the regional distribution of female transnational marriage migrants by nationalities in South Korea. In addition, this research explores the regional distribution by nationalities, migration processes, and socioeconomic characteristics of female transnational marriage migrants in Chungcheongbuk-do in South Korea. Regarding the regional distribution of female transnational marriage migrants in South Korea, using location quotient, this study seeks to categorizes cities and counties in South Korea into five groups. Furthermore, using Thomas method, this paper tries to stereotype cities and counties in Chungcheongbuk-do into six groups, in order to identify significant nationalities in each group. The concept of transnationalism refers to the recent phenomenon that transnational social networks are prominent, linking societies at the global scale, as international migration has been rapidly increasing due to the globalization. Transnationalism provides insight into the in-depth understanding of socio-spatial structure of international migrants, transnational social networks, transnational identities, cultural hybridization, and so on.

The male audience for melodrama, a typical women's genre, has drawn little attention in the audience research. Thus, this paper examines how and in what context they watch it, as well as how they accept and rationalize their 'feminine' taste. And in-depth interviews were conducted with seven middle-aged males. While they acknowledge their feminine taste, they tend to legitimize and re-contextualize it in ways that may not contradict their notion of masculinity. Consequently, they often demonstrate seemingly contradictory attitudes oscillating between enjoying it and distancing themselves from their please of viewing. Yet, their acknowledgement of feminization hardly extends to an acceptance of being labelled 'feminine' men. They attempt to distance themselves from emotional engagement in television viewing, either through emotional self-censorship or under-valuation of the taste for the genre itself. Finally, they hardly connect their taste for the genre to a sort of active post-viewing practices of fandom. The results have considerable implications for understanding how the melodrama-viewing males keep traversing the boundaries of gender-specific genres, and reconstitute the notion of masculinity.

The traditional masculinity has been gradually diversified towards the 21th century due to a new social environment. Men embrace his feminine side with heightened aesthetic sense using cosmetic products for better skin, hair, and nails. This diversification of male image and his beauty style proves the addition of feminity to masculinity. C. G. Jung felt that we are all really bisexual in nature. The anima is the female aspect present in the collective unconscious of men and it is the archetype through which we communicate with the collective unconscious generally, and it is important to get into touch with it for self-realization. This study analyzes subconscious desire based on the anima archetype in the collective unconscious of men through the diversity of the gender identity shown in men's cosmetic advertisements, and therefore it aim to help developing a marketing strategy of male beauty industry in the future. For this purpose, it conducted an empirical analysis of male beauty style in cosmetic advertisements through the Jungian anima theory. The conclusion of this study is as follows: First, gender identity represented in cosmetic advertisements was typified as Retrosexual, Ubersexual, Metrosexual, Cross sexual. Second, the anima archetype stimulates feminity in male beauty style. Cross sexual type has the highest feminine tendency. Third, range of utilization of cosmetic products is articulated with the diverse gender identity. Cross sexual type is most similar to the female beauty style. This feminization of male beauty style is the external expression of collective unconscious and affords human being to reach self-realization.

This study provides references that can be applied to future suit design by analyzing the formative characteristics of modern men's and women's suits. Research on related literature and case studies were carried out simultaneously. A criterion for analyzing formative characteristics of suits was drawn up through an examination of past research. A total of 1,410 suit photographs that appeared in the U.S. edition of Vogue Magazine from 1985 to 2008 were analyzed in order to observe the formative characteristics of men's and women's suits. Research results showed that in the 1980s suits pursued a more comfortable and natural fit based on the original properties of simplicity, modernity, and practicality; in addition, women's suits had a tendency to use excessive shoulder pads due to the power-look influence. In the early 1990s exaggerated shoulders and boxy straight silhouettes were in fashion but towards the later years suit designs gradually started to fit the body and established a skinny versus slouch conflict. Women's suits gradually began to show more curvy body lines, and men's suits became more feminine on the surface in terms of color and material. In the 2000s suits have become more feminine and sensual than the 1990s, design focuses of both men's and women's suits moved to the waistline. Skinny and long styles became the ideal silhouette and differences between formative characteristics of the two genders decreased. Fashion elements of men's and women's suits are seen to have changed with a mutual intimate connection under the influence of a similar societal environment.

Dietary restriction (caloric restriction) is the only intervention which has been reliably shown to extend the maximum life span of warm-blooded animals and delay the many phenomena associated with aging. It is also one of the most effective modulators of toxicity, especially cancer endpoints. In spite of the known modulator effects of caloric restriction, the biological mechanisms responsible for these effects had not been in vestigated until recently. The National Center for Toxicological Research (NCTR), in a collaborative effort with the National Institute of Aging (NIA), initiated a project whereby nine (9) combinations of rodent species/strains and diets were fed both restricted and ad libitum. The NIA's initiative was to identify biomarkers of aging whereas NCTR's initiative was to identify the biological effects associated with the profound effects caloric restriction has in protecting against both spontaneous (age-related) and chemically-induced toxic endpoints. Independent of sex or species, caloric restriction has similar effects on body temperature, oxygen consumption and $CO_2$production. Caloric restriction also decreased lipid glycolysis and metabolism in rats and mice, which suggest decreased production of metabolites which could lead to fatty acid epoxide formation. The age-associated loss of ciradian regulation of intermediate enzymes is also significantly reduced. Moreover, caloric restriction reduced the age-associated feminization of sexually dimorphic liver isozymes, increased several glucocorticoid responsive isozymes, elevated glucagon/insulin ratios, produced less microsomal superoxide and enhanced the capacity for utilzing detoxicating metabolic pathways. Calorically restricted rats have less than half the number of aflatoxin ($AFB_1$)-DNA adducts than ad libitum animals and urinary excretion of $AFB_1$ was increased significantly. Finally, DNA repair mechanisms are enhanced and oncogene expression is decreased in calorically restricted animals.

With the decrease of the agricultural population in Korea, the workers who is vulnerable to labor are increasing in agricultural industry because of aging, feminization of population. They are exposed in poor working environment with higher temperature and concentrations of dust, gas. Higher concentration of harmful gas and dust can cause chronic and acute disease to workers depending on exposure intensity and frequency. In order to improve the working environment in the livestock facilities, It is important to secure monitoring data of the thermal environment and the concentration of harmful gases and fine dust. Multi-point measurement was performed to analyze the regional environmental conditions in the pig rooms. When analyzing the working environment, video monitoring was conducted to analyze the concentration changes of ammonia, hydrogen sulfide and fine dust according to worker movement and work type. Ammonia and hydrogen sulfide monitoring result showed 1.5~2 times higher concentrations than other work when working in the pigs living zone, and 2~4 times higher than other work when working to increase the activity of pigs. In the case of fine dust, the result was 1.3 times higher than the worker's exposure standard in a specific work. The concentrations of gases and dusts from pig farms are not of concern for acute poisoning in normal work, but there is a risk of chronic respiratory disease if they are continuously exposed. Accordingly, there is a need for development of work environment monitoring device tailored to workers and preparation of alternatives.

Korea's population change trend is the aging and feminization as Reduction in mortality, average life extension. and is further increased Reduction of birth rate and aging population. if Our country concluded FTA(Free Trade Agreement) with the United States, Europe and China etc. labor-intensive industries will be the decline. Then, the construction workers' jobs are continually reduced. This is critical to the nation's economic, social and environmental influences due to Shortage of construction workforce and increasing labor costs. Eventually this is a major factor in reduced construction productivity. Therefore, this study is presented as a construction productivity development prospects on the value-added analysis per Labour productivity employee from Construction market trends, industry-specific productivity index, industry trends Employed, age tiered workforce trends, women's workforce trends, labor time trend, foreign workers, workforce trends, analysis of trends in construction contract, awarded by Company Size trends, construction management analysis index.

Wolbachia, vertically transmitted bacterial endosymbionts, is known to induce cytoplasmic incompatibility (CI), parthenogenesis, or feminization in some insect species. The Wolbachia found to exist symbiotically as a non-virulent form in Drosophila melanogaster, however popcorn is a lethal strain of Wolbachia, which causes tissue degeneration and early death of its adult host. Popcorn-infected flies showed the delayed duration of an egg and larvae, and their pupal period and life span reduced. The oviposition and egg-hatching rate of popcorn-infected flies were decreased 15% and 80%, respectiv~ly, compared to those of the normal Wolbachia-infected flies. The pupation and emergence rates of popcorn-infected flies were 67% and 65%, respectively. When popcorn-infected flies were crossed with Wolba-chia-infected flies, and vice versa, both crosses resulted in a significant reduction in egg production, egg¬hatching, pupation, and emergence rate, and their progeny revealed the popcorn syndrome. When popcorn-infected male flies were crossed with uninfected females, popcorn was not detected in their progeny. Popcorn also maternally transmitted in flies, but it did not induce CI and affected on its host life cycle as a virulence.
