The main object of this study was to understand the body image and body management behavior associated with desiring a thinner and more muscular body. The present study examined whether the drives for thinness and muscularity occur concurrently for both male and female college students, and whether there are gender differences. Moreover, the effects of objectified body consciousness on drive for thinness and drive for muscularity were investigated. A self-administered survey was conducted and a total of 390 data were used for data analysis. Participants included 197 male college students and 193 female students. Results indicated that male students reported significantly lower drive for thinness and higher drive for muscularity than female students. However, the drives for thinness and muscularity were significantly correlated for both male and female college students, and they reported discrepancies between their BMI and self-perceived weight and muscle mass. Findings supported the significant effects of objected body consciousness on the drives for thinness and muscularity for both male and females. Sub-dimensions of objectified body consciousness had differential effects on drive for thinness and muscularity. Specifically, body surveillance and body shame significantly influenced male and female students' drive for thinness, while their control belief did not have significant effects on their drive for thinness. Additionally, body shame emerged as significant unique predictor of drive for muscularity. In terms of gender comparisons, while the effect of body shame was the strongest for the males, the effect of surveillance was as strong as that of body shame for the females.

This study investigated the impact of appearance pressure from celebrities' social media upon internalization of mesomorphic ideal and muscularity dissatisfaction and the moderating role of time spent on social media in the relationships among variables in a sample of young Korean men (N=247). Those men who regularly participate in physical activities more than three times a week were included in our sample. Structural equation modeling analysis revealed that celebrities' social media pressure directly influenced both internalization and muscularity dissatisfaction, and internalization predicted muscularity dissatisfaction. A significant mediating effect of internalization in the relationships between celebrities' social media pressure and muscularity dissatisfaction was found. However, the moderating effect of time spent on social media was not found. The present results highlight the significant and negative effects of celebrities' social media on male's body image perception. By comparing the results of this study to previous studies, we can anticipate that the effects of social media on users' body image concerns can differ between male and female in the matter of time spent on social media. Implications of the study results and suggestions for future studies are discussed.

Selfie practices on social media can result in negative body image for men. The current study investigated the dual body image pathway model for the relationship between selfie practices on social media and body satisfaction, with internalization as a mediator. Structural equation modeling analyses supported our research model when studying 446 young Korean male Instagram users. The results indicated that selfie editing behavior, but not selfie browsing behavior, significantly predicted an increased internalization of a body ideal. The positive associations between internalization, muscularity dissatisfaction, and body fat dissatisfaction were confirmed. Additionally, the indirect effects of selfie editing behavior on muscularity and body fat dissatisfaction due to internalization were significant. The study confirmed the detrimental effects of selfie behavior on body satisfaction for male social media users. The results provided valuable information that selfie editing may be a risky behavior since it can result in developing muscularity and body fat dissatisfaction. Theoretical contributions and practical implications were discussed. Future research should address the age and cultural differences that may elucidate the impacts of selfie practices on men's body image concerns.

In the contemporary world, fashionable bodies are socially constructed in light of current idealized images. Media portrayal of such images can have negative health implications. This issue has long been problematic for women. Nowadays, men are subject to more scrutiny regarding their bodies, although male body image has been studied far less than female body image. In this position paper based on a review of the major studies that have been conducted on men and body image, we summarize the findings from these state-of-the-art studies that have been recently published in academic journals. Three themes related to male body image were extracted: socio-cultural ideals, masculinity, and minority men. This study adds to the literature I that it demonstrates that men experience and view their bodies differently from women, though some behaviors, such as disordered eating, are similar. Other behaviors, such as the drive for muscularity, are couched in the context of the social construction of gender and power. Most of the studies were done on white, heterosexual populations of young men, and nearly all used quantitative research methods. Little research has been conducted on ethnic and sexual minorities. We conclude with a discussion of what we need to know, and to that end, we suggest future avenues of research.

In the 21st century, men is expressing the femininity instead of the muscularity. And a boundary line between a man and a woman is not clear any more. A man is interested in the lifestyle of a woman, and he imitates her fashion styles, hairstyles, accessories, make-up, and plastic surgery. He is called as "Metrosexual" or "Crossexual". Nowadays, men as well as women can satisfy the wants for beauty. The beautiful appearance of a man has a good impact on the social relationships. The feminizing trends are generally accepted and are shown in the silhouettes, details, colors, fabrics and accessories. The feminizing trends in men's knitwear are shown in the various items. They have slim silhouettes and feminine details. Also they are made of bulky yarns or fancy yarns, and various stitches for texture effects. The most outstanding changes in men's knitwear are the vivid colors and flower patterns.

본 연구는 근대 이후 호동왕자의 서사가 어떻게 재현되었는지 정리하고 그 의미를 분석하는 것을 목적으로 한다. 호동왕자의 이야기는 12세기에 『삼국사기』에 처음 소개되었는데, 현재 TV 드라마, 영화, 소설, 희곡 등 다양한 갈래에 걸쳐 재생산되고 있는 대중적이며 민족적인 서사이다. 흥미로운 점은 『삼국사기』를 제외한 근대 이전의 문헌 속에서 호동왕자의 기록을 찾아 볼 수 없다는 사실이다. 호동왕자는 1935년에 이르러 윤백남에 의해 최초로 문학적으로 재현되었으며, 비로소 현재와 같은 대중성을 갖게 되었다. 즉 호동왕자의 이야기는 근대에 들어와 발견(명)된 '전통'의 표상 중 하나라 볼 수 있다. 윤백남을 필두로 이태준의 『왕자호동』, 유치진의 『자명고』로 이어지는 글쓰기들은 우리가 알고 있는 호동왕자의 성격들을 주조했다. 윤백남은 정사(情死)의 모티프를 삽입하여 낭만적 연인으로서의 호동의 모습을 만들어 냈고, 이태준과 유치진은 낙랑을 한사군 중 하나인 낙랑군으로 설정함으로써 민족(국가)주의적 컨텍스트를 삽입했다. 이 두 양상 모두 『삼국사기』에는 드러나지 않는 것으로, 위 작가들에 의해 고안된 것이다. 그리고 이렇게 삽입된 성격들은 각 텍스트들이 생산되었던 시기의 사회·정치적 상황과 밀접한 관련을 맺고 있다. 윤백남의 경우 과거를 노스탤지어의 대상으로 파악하는 근대적 미의식을 단면을 보여주고 있으며, 이태준의 경우 총동원체제를 (반)내면화하는 식민지 지식인의 사유체계를 보여 주고 있고, 유치진은 해방 공간 속에서 역사적 인물을 통해 민족의 남성성을 상상해내는 수법을 보여주고 있다. 바로 이렇게 서로 다른 맥락 속에서 소환되고 전유된 호동의 표상들이 모여 현재 우리가 알고 있는 '호동왕자'를 구축하고 있다고 말할 수 있을 것이다.

Breed differences in adult animals are determined during fetal development. If interventions are to be developed that influence growth of muscle and fat, it is important to know at which time during gestation breed differences appear and are fixed. The objective of this study was to characterize fetal development in cattle of different breeds. Pregnant cows of 4 cattle breeds with different growth impetus and muscularity were slaughtered under normal processing conditions and the fetuses were removed. German Angus, a typical beef cattle; Galloway, a smaller, environmentally resistant beef type; Holstein Friesian, a dairy type; and Belgian Blue, an extreme type for muscle growth were used. Fetuses of each breed were investigated at 3, 6, and 9 mo of gestation. Fetuses were weighed and dissected into carcass, organs, and muscles. Body fat weight was obtained using the Soxhlet extraction method. Fetal weight increased most rapidly in the third trimester of gestation mainly due to the accelerated muscle and fat deposition. The organ weight to body weight (BW) ratios decreased and the muscle and fat weight to BW ratios increased. At 3 mo of gestation, Galloway fetuses had the significantly smallest BW, half-carcass weight, leg weight, organ weight, muscle weight and shortest leg length. In contrast, Holstein fetuses had the significantly greatest BW, liver, kidney, and lung weights and significantly longest leg length among the 4 breeds, but no differences between Holstein Friesian and Belgian Blue were detected in half-carcass and leg weight. Indeed, Belgian Blue fetuses had the significantly greatest half-carcass weight, leg weight, and muscle weight at 9 mo of gestation, and Galloway had a significantly greater body fat to BW ratio than Holstein Friesian and Belgian Blue. These differences were not evident at 3 and 6 mo of gestation. These data show that the profound increase of tissue and organ weights occurred in later gestation in cattle fetuses even though breed differences were evident as early as 3 mo of gestation. Depending on the tissue of interest, impacting fetal growth likely needs to occur early in gestation before the appearance of breed-specific differences.

Myostatin, which is also known as growth and differentiation factor 8 (GDF8), has been reported to act as a negative regulator of skeletal muscle development. Variation in the myostatin gene (MSTN) has been associated with variation in muscularity in certain "meaty" sheep breeds. Polymerase Chain Reaction-Single Strand Conformational Polymorphism (PCR-SSCP) analysis was used to investigate allelic variation in the previously described g+6223G>A single-nucleotide polymorphism (SNP) in the 3' untranslated region (3' UTR) of MSTN. The sheep studied were 79 New Zealand (NZ) Romney lambs derived from a single sire heterozyous for g+6223G>A, which is in itself notable as this polymorphism has not been described previously in this breed. Allelic variation was observed to be associated with an abnormal gender ratio (p = 0.046) in the progeny. The presence of allele A was observed to have an effect (p<0.05) on birth weight, mean loin yield, proportion yield loin and total muscle yield. Allelic variation did not significantly affect mean shoulder yield, leg yield, proportion yield shoulder and proportion yield leg. This preliminary result suggests that while the A allele at MSTN g+6223 appears to improve some valuable traits in NZ Romney sheep, further research is required to understand if and how it may affect other traits.

The present study was conducted to determine the best level of substitution of soybean meal by sunflower cake in diets for kids through the evaluation of quantitative carcass traits. Thirty-two Boer kids X 1/2 NDB (no defined breed), males, non-castrated, with 4 months of age and initial body weight of $15{\pm}3.2$ kg, were randomly assigned to individual pens. The treatments contained four substitution levels of soybean meal by sunflower cake (0, 33, 66 and 100% DM). At the end of the experimental period, the animals were slaughtered. There was no influence of the treatments on any of the mean values of the evaluated measures (p>0.05): 21.78 kg (body weight at slaughter), 8.65 kg (hot carcass weight), 8.59 kg (cold carcass weight), 40.27% (hot carcass yield), 39.20% (cold carcass yield), 7.73 $cm^2$ (rib eye area), 46.74 cm (carcass outer length), 45.68 cm (carcass internal length), 36.92 cm (leg length), 26.04 cm (leg perimeter), 48.66 cm (hind perimeter), 58.62 cm (thoracic perimeter), 0.20 (carcass compactness index), 68.48% (total muscle of the leg), 2.79% (total leg fat), 55.19% (subcutaneous leg fat), 28.82% (total bone), 81.66 g (femur weight), 14.88 cm (femur length), 0.38 (leg muscularity index), 2.53 (muscle:bone ratio) and 33.42 (muscle:fat ratio). The substitution of soybean meal by sunflower cake may be recommended up to a level of 100% without alterations to quantitative carcass traits.

During a 5-yr period, 1994-1998, pre-weaning and weaning data were collected on 591 calves produced by mating either straightbred Jersey, straightbred Limousin or $F_1$ (Limousin${\times}$Jersey) bulls to mature purebred Jersey or Limousin cows. Traits recorded included birth and weaning weight, height, length, girth, fat depth and a measure of muscle (ratio of stifle to hip width expressed as a percentage). All traits were analyzed assuming a model with sire and dam random effects that included effects of year and date of birth, sex, breed and year${\times}$sex interaction. Main effects were generally significant with few exceptions. Direct genetic effects were large for weight, height, girth and muscle with a breed trend from purebred Jersey (small) to purebred Limousin (large). At weaning, the maternal effect of the Jersey dam was positive for weight (10.9${\pm}$4.9 kg), girth (3.7${\pm}$1.0 cm) and muscle (6.0${\pm}$0.9%). Heterosis was highly significant and positive only for fat depth (1.5${\pm}$0.2 mm) with the $F_1$ progeny being the fattest, followed by the backcrosses, then purebred Jersey and purebred Limousin. Also, significant (p<0.001) but negative heterosis was observed for weight, girth and muscle. The change in ranking for fat depth relative to other traits is a reflection of the large heterotic effects relative to direct effects on fat depth. Epistatic effects were not significant on any trait at birth or weaning. This study has indicated the possibility of exploiting the positive heterotic and maternal effects for fat depth and muscularity to meet specific meat quality and quantity demand by consumers.
