This study was carried out to investigate the effect of cysteamine addition during in vitro maturation, fertilization and culture of porcine oocytes. Oocytes were matured for the first 22 h in mTCM -199 media supplemented with or without 150 $\mu$M cysteamine. They then were matured for an additional 22 h in mTCM-199 media without hormones supplemented with or without 150 $\mu$M cysteamine. When cumulus-oocyte complexes (COCs) were matured in the mTCM-199 media supplemented with cysteamine, the rates of GVBD and maturation (metaphase II) were enhanced as compared to the media without the addition of cysteamine. Also, when COCs were matured in the mTCM-199 media supplemented with cysteamine, the rates of sperm penetration, male pronucleus formation, cleavage and blastocyst formation after in vitro fertilization were enhanced as compared to the media without the addition of cysteamine. In conclusion, it was suggested that oocytes matured for the first 22 h in mTCM-199 media supplemented with 150 $\mu$M cysteamine increased the rates of metaphase II, sperm penetration, male pronucleus and blastocyst formation were higher as compared to the media without addition of cysteamine.

This paper is intended to explore femininity the ideal beauty of body and the features in fashion pursued in the Fashion system and the Anti-Fashion Movement in the Victorian period, on which the modern fashion is based. For the informative facts needed in this paper, books on history, fashion history, feminism, art history of aestheticism and the ideal beauty of body are referred to. On the part Ⅱ of this paper, the femininity and the ideal beauty of body implied in the Aesthetic Movement and Rational Dress Movement as the anti-fashion movement in the Victorian period will be reviewed. Following are the conclusion : First, the works in Aesthetic Movement mainly include the image of sensual female. The essence of femininity is categorized by cultural value, poetic spirit. appetite for sex and self-expression. The ideal beauty of body pursued in this movement is the beauty of immatured body, which means rejection of maternity as well as appetite for sex in the form of metaphor of the power and enthusiasm of female. The features of Aesthetic Movement emphasize the image of sensual and characteristic woman. These features are expressed in the natural waist line and the vertical H silhouette of high waist, natural exposure of body by means of drapery, simplicity and decency by design without fixed forms and seemingly faded colors. Second, Rational Dress Movement attempted to evaluate the femininity in a different way and ultimately pursued masculinity. Therefore, morality, liberty, intelligence, spirituality, self-control, willingness, which had been believed to exclusively belong to male, are added to the categories of femininity. The ideal beauty of body is expressed in the form of Venus Coelestic which is refined and strong. This symbolizes woman's freeing from the fate of reproduction and subordinate relationship with male, morality, decision of one's own and willingness. The features of Rational Dress Movement represent the image of strong-willed and moral woman in its internal meaning. The features of its fashions represent the concealment of the body, emphasis on activeness in pants without decoration and simplicity in its external form. All these features resulted from the pursuit of masculinity.

For the informative facts needed in this paper, books on history, fashion history, feminism, art history of aestheticism and tole ideal beauty of body are referred to. On the part I of this paper, the femininity and the ideal beauty of body implied in the fashion system in the Victorian period will be reviewed. following are the conclusion : First, in the Victorian period, the value of femininity is put on the body of female by the discrimination of sex divided in two. Consequently, the characteristics of femininity mainly include dependence, passiveness, emotion, beauty, maternity, innocence, and purity. To emphasize the function of reproduction as primary duty and nature of female, the ideal beauty of body is represented in the form of Venus Naturalis, which symbolizes the fertility. And the external form of this body is expressed in slum waist line, ample busom and hip in fashion. Second, the features of this fashion are classified into three categories by their internal value : images of subordinate female, sensual female and maternal female 1) The image of subordinate female is expressed by concealment of legs, tightening the upper part of the body in corset and restriction on action by the crinoline 2) The image of sensual female is revealed in brazing colors and decoration, excessive exposure of the upper part of the body and hip by means of bustle. 3) The image of maternity is expressed in swollen skirt of crinoline, oval bustle silhouette metaphoring the extended womb resulted from pregnancy.

Transgenes in HSY-TK gene driven by the lck promoter was tested for the expression in immune cells (Jurkat cells) to apply xenotransplantation of human cells into transgenic animals for the potential use of the proliferation or differentiation of human stem cells in the large animal such as an pig. Also, lck-CFP gene was used for transfection experiment into Jurkat cell to confirm the proper regulation of lck promoter for transgene expression in the T cells. Transfection of lck-GFP gene into Jurkat ceils induced CFP expression in transfected cells. The expression of Ick-TK and Ick-CFP genes was confirmed by RT-PCR using RNAs extracted from Jurkat cells, When Jurkat cells transfected with TK and CFP genes were selected against G418 or gancyclovir treatments, Jurkat cells transfected with TK gene were not proliferated in G4i8 and gancyclovir medium while intact cells or cells transfected with CFP gene could grow in gancyclovir medium. However, Jurkat cells transfected with TK or GFP gene were proliferated in G418 medium probably due to Neo$^{r}$ gene in the vector. Gancyclovir treatment destroyed Jurkat cells expressing TK gene indicating that T-cells expressing TK gene can be selectively eliminated by TK gene expression driven by lck promoter.

The image as a media has changed consistently since it was first introduced. According to these changes, the image has been reproduced in different fields and contexts. Thus, the paradigm on the production and the consumption of the image has been changed and recycled rapidly. The relation between the production and the consumption of the image also has changed accordingly, allowing quite ambiguous distinction between the producer and the consumer. The transformation through the transfer of the image among different fields opens up a new potential that these reproduced images could be used as an aesthetically expressive tool, rather than merely leaving images to remain royal to its original function as a sign. The thesis is to explore the potential that the topographical lines have beyond its function as a sign age. During the reproduction of the image, the process actively invites the spectator or the consumer to participate in the formation of the image, which promotes a new relation between the producer and the consumer. Instead, the process encourages the consumers to be active producers as well. As a result, the topographical lines do not merely remain as a sign that demarcates the height of the topography, and new images are constantly reproduced from the active participants. This project questions the fixed idea on the sign as a communicative tool, and suggests a new potential for the sign, especially, the topographical lines.

This study was constructed the correlations of the embryonic developmental rates and the frequency of chromosome aberration using ear-skin-fibroblast cell in nuclear transfer (NT) derived embryos. Karyoplast-oocyte complexes were fused and activated simultaneously, then cultured for seven days to assess development. The developmental rates of NT and in vitro fertilization (IVF) embryos were 55.4% vs 63.5%, 31.7% vs 33% and 13.4% vs 16.8% in 2 cell, 8 cell and blastocyst, respectively. Firstly, the frequency of chromosome aberrations were evaluated using fluorescent in situ hybridization (FISH) technique with porcine chromosome 1 submetacentric specific probe. Chromosome aberration was detected at day 3 on the embryo culture, the percentages of chromosomal aneuploidy in NT and IVF embryos at 4-cell stage were 40%, 31.3%, respectively. Secondly, embryonic fragmentation was evaluated at 4-cell stage embryo. Frequency of embryonic fragmentations was in 51.3% of NT, 61.3% of IVF, 28.9% of parthenogenetic activation at 4-cell stage. The proportion of fragmentation in NT embryos was higher than activation embryos. This result indicates that chromosomal abnormalities and embryonic fragments are associated with low developmental rate in porcine NT embryo. It is also suggest that abnormal porcine embryos produced by NT related with lower implantation rate, increased abortion rate and production of abnormal fetuses.

This study investigated the mathematical notation used today in terms of skip ping the parenthesis. At first we have studied the elementary and secondary curriculum content related to omitted rules. As a result, it is difficult to find explicit evidence to answer that question 'What is the calculation of the $48{\div}2(9+3)$?'. In order to inquire the notation fundamentally, we checked the characteristics on prefix, infix and postfix, and looked into the advantages and disadvantages on infix. At the same time we illuminated the development of mathematical notation from the point of view of skipping the parenthesis. From this investigation, we could check that this interpretation was smooth in the point of view that skipping the parentheses are the image of the function. Through this we proposed some teaching methods including 'teaching mathematical notation based on historic genetic principle', 'reproduction of efforts to overcome the disadvantages of infix and understand the context to choose infix', 'finding the omitted parentheses to identify the fundamental formula' and 'specifying the viewpoint that skipping the multiplication notation can be considered as an image of the function'.

Lithography like off-set printing is processed using the repellent properties between water and oil, so all inks for off-printing must work with dampening solution(water). The dampening water may cause the emulsification of ink by the printing pressure in the printing nip. This study aimed to investigate the effect of emulsified inks on print mottle. The cyan ink was emulsified artificially with the different IPA(isopropyl alcohol) content in this study. We evaluated the print mottle by densitometer and image analysis method. The print mottle phenomenon was directly affected by IPA content. The emulsification of inks also had an influence on flow properties of inks and it increased ink transfer rate. It, however, caused low ink density. Moreover the emulsified inks were spreaded to around dots and cause the thinning density on the non-printing area like print mottle. The trial printing showed that the emulsified inks also cause scumming on the printing result with little mistake of adjusting dampening solution and mostly decreasing dot reproduction. We could, therefore, find out the obvious effect of emulsified inks on print mottle.

Here, we present an approach of blood plasma proteome profiling and their comparisons between the young and the adult pigs as prerequisite for the identification of bio-markers related to the health conditions, growth performance and meat quality. To profile the proteome in porcine plasma, blood samples were collected from 19 young piglets and 20 adult male barrows and the plasma was retrieved. Then, protein profiling was initiated using one and two-dimensional electrophoresis. Proteins were spotted and then identified by MALDI-TOF-TOF and LC-MS-MS. In the results, more than thirty-six and twenty eight protein spots were selected in young piglets and adult pigs, respectively and twenty three proteins were identified. The proteome profile images were compared between those ones using Image Master Version 7.0. The image of expressed proteome showed that most of proteins from plasma of young piglet separated clearly and concentrated in 2DE display compared to ones from adult. Image analysis in detail was carried out to look for the specific proteins related to age progression. It demonstrated that the characteristics of proteome expression could be distinct to their age stages. Further investigations needed to proceed to understand the age dependent change of protein conformation and biological meaning of those differences in proteome expression between young and mature adult pigs.
