  • Biodegradation of fat, oil, and grease (FOGs) plays an Important role in wastewater management and water pollution control. However, many industrial food-processing and food restaurants generate FOG-containing waste waters for which there Is no acceptable technology for their pretreatment. To solve these problems, this study evaluated the feasibility of effective FOG-degrading microorganisms on the biodegradation of olive oil and FOG-containing wastewater. Twenty-two strains capable of degrading FOGs were isolated from five FOG-contaminated sites for the evaluation of their FOG degradation capabilities. Among twenty-two strains tested, the lipase-producing Pseudomonas sp. strain D2D3 was selected for actual FOG wastewater treatment. Its biodegradability was performed at 3$0^{\circ}C$ and pH 8. The extent of FOG removal efficiency was varied for each FOG tested, being the highest for olive oil and animal fat (94.5% and 94.4%), and the lowest for safflower oil (62%). The addition of organic nitrogen sources such as yeast extract, soytone, and peptone enhanced the removal efficiency of FOGs, but the addition of the inorganic nitrogen nutrients such as $NH_4$Cl and $(NH_4)_2SO_4$ did not increase. The $KH_2PO_4$ sources in 0.25% to 0.5% concentrations showed more than 90% degradability. As a result, the main pathway for the oxidation of fatty acids results in the removal of two carbon atoms as acetyl-CoA with each reaction sequence: $\beta$-oxidation. Its lipase activity showed 38.5 U/g DCW using the optimal media after 9 h. Real wastewater and FOGs were used for determining the removal efficiency by using Pseudomonas sp. strain D2D3 bioadditive. The degradation by Pseudomonas sp. strain D2D3 was 41% higher than that of the naturally occurring bacteria. This result indicated that the use of isolated Pseudomonas sp. strain D2D3 in a bioaugmentating grease trap or other processes might possibly be sufficient to acclimate biological processes for degrading FOGs.

  • The ischemia-responsive 94 gene (irp94) encoding a 94 kDa endoplasmic reticulum resident protein was investigated its molecular properties associated with unfoled protein responses. First, the expression of irp94 mRNA was tested after the reperfusion of the transient forebrain ischemia induction at the central nervous system in three Mongolian gerbils. Second, irp94 expression in PC12 cells, which are derived from transplantable rat pheochromocytoma cultured in the DMEM media, was tested at transcriptional and translational levels. The half life of irp94 mRNA was also determined In PC12 cells. Last, the changes of irp94 mRNA expression were investigated by the addition of various ER stress inducible chemicals (A23187, BFA, tunicamycin, DTT and $H_2O_2$) and proteasome inhibitors, and heat shock. High level expression of irp94 mRNA was detected after 3 hours reperfusion in the both sites of the cerebral cortex and hippocampus of the gerbil brain. The main regulation of irp94 mRNA expression in PC 12 cells was determined at the transcriptional level. The half life of irp94 mRNA in PC12 cells was approximately 5 hours after the initial translation. The remarkable expression of irp94 mRNA was detected by the treatment of tunicamycin, which blocks glycosylation of newly synthesized polypeptides, and $H_2O_2$, which induces apoptosis. When PC12 cells were treated with the cytosol proteasome inhibitors such as ALLN (N-acetyl-leucyl-norleucinal) and MG 132 (methylguanidine), irp94 mRNA expression was increased. These results indicate that expression of irp94 was induced by ER stress including oxidation condition and glycosylation blocking in proteins. Expression of irp94 was increased when the cells were chased after heat shock, suggesting that irp94 may be involved in recovery rather than protection against ER stresses. In addition, irp94 expression was remarkably increased when cytosol proteasomes were inhibited by ALLN and MG 132, suggesting that irp94 plays an important role for maintaining the ERAD (endoplasmic reticulum associated degradation) function.

  • Purpose: The purpose of this study is to understand a variety of intervention studies to prevent smoking by adolescents in U.S. and find out implications for Korea. Methods: This study reviewed articles found in the internet and analysed the data of US DHHS and CDC. Results: The School Health Policies and Programs Study (SHPPS) is a national survey periodically conducted to assess school health policies and programs of U.S. The main components of SHPPS are health education and physical education, health services, mental health and social services, school policies, and school environments. The CDC guidelines for school health programs to prevent tobacco use and addiction are composed of policy, instruction, curriculum, training, family involvement, tobacco-use cessation efforts, and evaluation. School-based interventions to prevent smoking can be classified into the categories of information-giving curricula, social competence curricula, social influence approaches, combined methods draw on social competence and social influence approaches and multi-modal programmes and Youth Empowerment study. The key programs for adolescent smoking prevention are ALERT Project, HSPP, TNT Project, MPP, NC YES. Conclusions: As smoking is often the first step of unhealthy behaviour such as alcohol drinking, illegal drugs, and violence, smoking prevention programmes for adolescents in U.S. have been comprehensive school-based health programs. In smoking prevention programs for adolescents, CDC plays a critical role by supporting survey, research, policy, and funds. The effectiveness of the programs was high when it was based on school and involved parents, community, and mass media. As the effect of each programme is not expected to last for a long time, consistent repetition of these interventions is essential. Current smoking prevention programs for adolescents are exploring the empowerment approach focused on the active involvement of participants rather than traditional approaches using order and discipline.

  • Most of studies on the press during the period of Japanese occupation in Korea have focused on the activities of newspapers in 1920s. These past studies didn't examine the whole process of change of the press under the Japanese occupation in Korea. Thus, this study tried to investigate the change of the tenor of Korean newspaper editorials on the ruling policies during the end of the colonial period in Korea as a part of attempts exceeding the limit of past studies. After the outbreak of the war between China and Japan in 1937, the Korean newspapers were full of stereotyped editorials resembling in a way official gazette. Dong-A Ilbo and Cho-Sun Ilbo represented the purpose of the war was to emancipate Asian countries from Western imperialist countries and to establish the peace of the Asia. Simultaneously, two newspapers played an important role in assimilating the Korean people into the Japanese and mobilizing them to the war, The tenor of these editorials was affected by intensified control over the press and the change of the consciousness of journalists. In conclusion, these newspapers had a harmful influence on the Korean people as a weapon to the movement to organize and mobilize them. Therefore the interest for researching on the pro-Japanese press should be taken in view of 'resistance' and 'collaboration.'

  • Antioxidants were well known to be essential supplements in the complex media and serve as a reservoir of oxygen. In this study, Hanwoo COCs (cumulus oocytes complexes) were matured and developed in L-cysteine-TCM199 and analyzed metaphase chromosome. Maturation rate of Hanwoo COCs were 73.4%, 94.6% in 0.1% PVA, 0.1 mM L-cysteine, respectively and showed significantly different between the treatments (p<0.05). Blastocyst formation were revealed 20.3%, 10.0% in 5% FBS+TCM199, 0.1 mM L-cysteine+1% BSA, respectively. There were no significant difference among treatment groups. Metaphase chromosome were showed 18.3%, 12.0% in 5% FBS-TCM199, 0.1 mM L-cysteine, respectively and analyzable chromosome were 6.1%, 4.0% and had no differences between the treated groups. In the case of in vitro developmental stages, metaphase chromosome were showed 18.3%, 12.0% in $4{\sim}16$ cells stage, 43.1%, 13.0% in morulae stage and 94.8%, 100.0% in blastocyst stage. These results suggested L-cysteine has beneficial role for in virto maturation and development in Hanwoo COCs.

  • This research investigates the systematic relation between corporate governance and corporate social responsibility(CSR). Based on the argument that corporate governance would play the role of mitigating conflicts between firms and society, we hypothesized that corporate governance would enhance CSR performance. Specifically, the firms with good governance are predicted to have CSR performance than those with bad governance. These hypotheses were tested using 130ce rean firms from 1998 to 2005. An index published by e rean Economic Justice mance the(KEJm) was used as the measureses wSR performance. Our empirical results suggest that the firms with good governance as measured by f reign investh bad goothshae directh bad goirdit committee exhibit better CSR performance. The primary purposeses this s tdy is to identify the determinants es the use b' satissaction and commitment in pe bn thomedia. For these purposes, we developegoi research modehobased on the literaturesreviews es pe bn tho media, pe ceived risk and interactivity, satissaction, and commitment. This study has identified four dimensions in the concept of perceived risk, such as privacy risk, social risk, time loss risk, and economic risk, and three dimensions in the concept of perceived interactivity, such as active control, two-way communication, and responsiveness.

  • This paper reviews battering, sexual violence and divorce experienced among women. There three problems have negative influence on health status in women and are further developed to social problems such as family dissolution. The victims of the problems may manifest physical injury, emotional difficulties and social withdrawl, while their children may show problems caused by lack of parental caring and by resembling abusive behaviors of their parents. Hence, nurses need to pay attention to batting, sexual violence, and divorce and to develop relevant nursing interventions for them. Some strategies of dealing with those problems are presented in the following. First, we have to eliminate sexism prevailing in out society. Our society is assigning inequal and asymmetrical gender role. Mass media should inspire equality between genders and show a healthy model of family and community. Second, social system and laws should be changed through collective efforts. Those living conditions of women cannot be changed by the effort of women themselves only. We all need to work for establishing and changing the law, so that those women in suffering can obtain immediate and adequate protection. Third, social support system of consulting and referring women's problems should be established. Such support system as hot line, shelter and counseling clinics would help women in crisis. Fourth, job training and arrangement should be available to women who are divorced. Fifth, there should be self-help group for those women in suffering. Self-help group would help those women in sharing their problems and feelings and in establishing coping strategies. Nurses, as the largest group among health professionals, are sensitive and respond to health needs of clients and have an effect on managing women's health. However, we nurses have not been ready for dealing with problems of women, although most of us are women. we not need to change our perspective of women's health problems from a traditional medical perspective to feministic one. Accordingly, nurses need to develop realistic way of caring those women in suffering and to assist them in making decisions for their lives by themselves.

  • Focused on the performance of interactivity in the appreciation of media art, this study is associated with the continually changed art texts and a participator's physical reactions to savor the art. Digital works of art emphasizing interactivity usually decentralize and disperse the responsibility and the central role for creating and producing the art works. Proper procedure of the work is generated by actions such as clicking the mouse, controlling the joy stick or actual movement of anticipators' bodies. The art works are influenced by participators' interactivity, which makes the leading roles and the responsibility for creating art scattered and divided. These features are similar with those of the 'Rhizome' which Gilles Deleuze(1925~1995) and Felix Guattari(1930~1992) have discussed. In their argument, 'Rhizome' is an interval or being 'between', which keeps changing. 'Rhizome' is a state in which the individual and the work of art never reach the conclusion, only a phenomenon of eternally altering. Like 'Rhizome', this sort of art work has the decentralized system, opens for several directions, and activates the system which is changeable as linked items increased or decreased. These works stimulate the individual to perform and act while appreciating the art piece. In terms of processing and preceeding, interactivity is the important equipment and catalyzer. Through these procedures, the pieces can be the 'floating work of art' combined and condensed with the whole participators' reactions. The 'floating work of art' is neither the expression of an individual nor that of one particular group. Multidimensional influence of the web is the web which is constantly reorganizing and producing in its connective state. This connective state is activated by interactivity. The Rhizomatic system embodies the floating work of art process. Due to each individual perceiving art in individualistic terms, there is no dominating powers or central points. I regard this art works possessing above traits as the work of art with Rhizomatic system. The work of art with the Rhizomatic system is embodied through interactivity and because physical action activates the process of appreciation, a participator can actually experience and practice the philosophy. Ultimately the Rhizomatic speculation occurs during the interactivity of appreciating the Rhizomatic art pieces. The Rhizomatic system penetrates into the intuitive area beyond our recognition and thoughts, as we are engaged in the connective process. With the methods and manners of interactive art, we can possibly reconsider the system as a tool in which the participator is directly able to link experience and theory to the philosophies of Deleuze and Guattari.

  • This study focuses on the cultural and economic effects created by long-term TV dramas that run more than 20 years. The result of this study shows that long-lasting TV dramas have significant influence in increasing audience ratings of TV broadcasting companies. An analysis of Fuji Television's "From the Northern Country" shows that the drama's audience rating has more than doubled at the end period in comparison to that at the beginning stage. The analysis shows that long-term dramas also greatly contribute to the improvement of nation's cultural capability including contents development competence by producing media contents related professionals such as actors, actresses and dramatists. Fuji Television picked an actor and an actress for the drama and kept developing their talent and make a cultural accomplishment to produce new talents who compete with performance ability for the Japanese Entertainment Business. In addition, long lasting TV dramas appear to significantly contribute to local economy by promoting tourism industry of the areas where dramas are filmed. By introducing Hurano in Hokkaido which was the main stage of "From the Northern Country" to Japanese people for 21 years, the drama played a decisive role in building Hurano's brand power.

  • The term "new woman" (신여성 [Sinyeoseong], 新女性) refers to an idealized image of contemporary women during the so-called modern period in East Asia. In Korea, these "modern girls" were also referred to as modan (毛斷), or "cut-hair", reflecting changes in appearances that rejected the traditional value system in favor of "the new" in everyday life. Although it was used to refer to the perceived educated leaders of this new period, it also had the negative connotation of referring to frivolous women only interested in the latest fashion. The popular discourse on this "new woman" was constantly changing during this early modern period in East Asia, ranging from male-driven women's movements to women-driven liberal and socialist movements. The discourse often included ideals of what constituted female impeccability in women's domestic roles and enlightened views on housekeeping, yet in most cases the "new woman" was also expected to be a good wife and mother as well as a successful career woman. The concept of the "new woman" was also accompanied by an upheaval in women's social roles and their physical boundaries, and resulted in women repositioning themselves in the new society. The new look was a way of constructing their bodies to fit their new roles, and this again was rapidly reproduced in visual media. Newspapers, magazines, and plays had gained immense popularity by this time and provided visual material for the age with covers, advertisements, and illustrations. This research will explore the fashion of the "new woman" through archival resources, specifically magazines published in the 1920s and 1930s. It will investigate how women's appearances and the images they pursued reflected the ideal image of the "new woman." Fashion information providers, trendsetters, and levels of popular acceptance will also be examined in the context of the early stage of the fashion industry in East Asia, including production and distribution. Additionally, as the idea of the "new woman" was a worldwide phenomenon throughout the 19th and early 20th century, the effect of Japanese colonialism on the structure of Korean culture and its role as a cultural mediator will also be considered in how the ideal image of beauty was sought, and whether this was a western, colonial, or national preference.
