This article is to understand the implications and ideological meaning of female normative beauty reproduced by the idealizing phenomena of the hyper-real body as a process of the normalization of the body projected in fashion magazines with a focus on the body created by the increased influence of mass media in consumer capitalism. This study conducts a literature research and semiotic analysis as the method of investigation and focuses on the body images of the beauty articles in Vogue Korea. The idealizing phenomena of the hyper-real body in fashion magazines emphasizes that the body is an exchangeable substance that can be disassembled to adjust to accord with the standards and norms of society, that the ability of individuals to manage their body is enhanced by a rise in social class, and concludes that the superficial alteration of the body image is related to the standard of a moral tendency where a young and slender figure is considered to be a well managed body image.

With the development of video-related applications, media content has increased dramatically through applications. There is a substantial amount of near-duplicate videos (NDVs) among Internet videos, thus NDVR is important for eliminating near-duplicates from web video searches. This paper proposes a novel NDVR system that supports large-scale retrieval and contributes to the efficient and accurate retrieval performance. For this, we extracted keyframes from each video at regular intervals and then extracted both commonly used features (LBP and HSV) and new image features from each keyframe. A recent study introduced a new image feature that can provide more robust information than existing features even if there are geometric changes to and complex editing of images. We convert a vector set that consists of the extracted features to binary code through a set of hash functions so that the similarity comparison can be more efficient as similar videos are more likely to map into the same buckets. Lastly, we calculate similarity to search for NDVs; we examine the effectiveness of the NDVR system and compare this against previous NDVR systems using the public video collections CC_WEB_VIDEO. The proposed NDVR system's performance is very promising compared to previous NDVR systems.

This essay examines Toni Morrison's African-American characters' struggle in The Bluest Eye (1970) and Home (2012) through the lens of heteronormativity, arguing that they suffer double victimization due to both their race and gender. The Bluest Eye portrays a family tragedy caused by an African-American husband and wife's failure to live up to images of gender as represented in white, middle-class media. Written forty-two years later, Home describes an African-American man and woman who establish their own lives away from gendered standards after striving to meet social expectations and becoming traumatized in the process. Their adversities stem not only from the deeply rooted racial discrimination in American society but also from subtle gendered norms implanted by heteronormativity. Morrison's characters in her earlier narrative face a tragic denouement, ultimately destroying their children's lives. By contrast, Morrison's later characters explore more utopian ways of life unfettered by heteronormativity, overcoming hardships imposed by white-centered heteronormal society. By portraying socially victimized characters, Toni Morrison problematizes the power behind the discriminatory nature of heteronormativity and suggests a more gender-neutral, egalitarian way of organizing society, free from the constraints of heterosexuality and from violence created by normalized gender rules.

Purpose: A good physical appearance greatly affects a person's self-confidence, especially when the media constantly depicts that beautiful men and women are those with perfect bodies, which later forms the perception that being fat or too thin is not attractive. That is in line with the increasing knowledge and the need for nutritious foods and drinks for diets. Therefore, this study aims to see whether there is a relationship between the Weight Rejuvenation Program Everyday product innovation towards millennial purchase decision and the motivation of having an ideal body as a moderating effect. Research design, data, and methodology: Distributed online Google form questionnaires to 96 audiences who commented on "Mute" web series. The respondents consisted of 63 women and 33 men from the millennial generation who lived in Greater Jakarta and were classified as the middle to upper economic class. After all of the data were collected, they were processed using Structural Equation Modeling Partial Least Squares. Results: Product innovation had a significant influence on the purchasing decisions of the millennial consumer, but motivation did not have the moderating function in the relationships between product innovation and purchase decision. Conclusions: The main factor for product innovation that can be accepted by millennials is the product quality that remains good.

Although blogs have been used in online learning environments with optimistic expectations, the distributed nature of blogs can pose some challenges. Currently, we do not have a robust collection of tested blogging strategies to help students interact more effectively with each other when blogs are used as a primary form of engagement in an online class. Thus, the purpose of the study was to test an early iteration of an instructional blogging strategy, "Featured Student Profiles," which is designed to help students become acquainted with each other better and encourage them to visit and comment on each other's blogs. Sixteen pre-service teachers who were enrolled in an online course in which student blogs are the primary medium of peer interactions, participated in the study. Using a design case approach, seven students participated in interviews and all student blog interactions were analyzed. Thematic analysis was applied to analyze the interview data and identify salient themes of students' blogging experiences overall under the study strategy. The findings indicated that students took the most direct and efficient path they experienced to complete the blog task. Their peer interaction patterns varied, but several shifted from random to targeted relationships as the semester progressed. Although all students perceived the strategy as a positive approach to peer awareness, there was no clear evidence of its effect on student interactions.

In the post-information era, most of technologies have a visual part, or at least some functions related to visualization. It is also one of the popular means of presenting materials in education area. However, despite its popularity, the impact of visualization on the effectiveness of learning still remains controversial. Even more controversial is its usefulness in developing creativity, which is one of the most important skills for today's employee. The authors considered the use of visualization as a tool for the development of children's creativity on the example of learning video games, in particular, ClassCraft to distinguish features that, from the point of view of psychology, may lead to developing creativity even being not useful for educational purposes. It is concluded that video games useful for learning may have features, that are inappropriate in formal educational context, but important to develop creative thinking.

Monoclonal antibodies (MoAbs) are a highly diversified class of proteins with major research and commercial applications such as diagnostics and therapeutics. Currently, the dominant method for producing MoAbs is through the hybridoma technique. However, this technique is slow, tedious, labor intensive, and expensive. The production of MoAbs in cultured transgenic plant cells can offer some advantages over that in the over that in the mammalian systems. The media to cultivate plant cells are well defined and inexpensive. Contamination by bacteria or fungi is easily monitored in plant tissue cultures. Furthermore, these contaminants are usually not potent pathogens to human beings. In our interdisciplinary research efforts, heavy chain monoclonal antibody (HC MAb) was inserted into Ti plasmid vector and transferred into A. tumefaciens for the transformation in tobacco cells. It was found that 76% of the transformants produced HC MAb. The presence of HC MAb in the cell membrane fraction indicated that the signal peptide was functional and efficient. The change of the HC MAb concentration during a batch culture followed a similar trend as dry cell concentration, indicating that the production of HC MAb was growth related. The long-term repeated subcultures of 11 cell lines showed that there was no obvious trend of neither the decrease nor the increase of the productivity with the repeated subcultures.
