  • The aim of this study is to determine the phagocytosis-promoting factor(s) for feline peripheral blood polymorphonuclear cells (PMN) by culture supernatant from mono-nuclear cells (MNC) treated with egg white derivatives (EWD). The phagocytic activity of PMN was analyzed by a flow cytometry system. The EWD did not show direct effect on the phagocytic response of PMN. The phagocytic activity of PMN was enhanced by culture supernatant from MNC but not PMN treated with EWD. Therefore, it was suggested that the enhanced phagocytic activity of feline PMN could be mediated by humoral factor(s) released from MNC treated with EWD. Thus, the phagocytosis-promoting factor(s) in supernatant fraction from MNC culture treated with EWD were isolated by reverse phase high pressure liquid chromatography. The resulting supernatant fraction on 29.02 minutes of retention time showed high phagocytic activity of PMN. The molecular weight of this supernatant fraction was 16 to 18 kDa when analyzed by capillary electrophoresis. The isoelectric point was pH 5.76 when assessed by ion-exchange chromatography. These results suggest that EWD stimulates feline MNC to elaborate a phagocytosis-promoting factor, 16 to 18 kDa of molecular weight, which could be an important mediator for the enhancement of phagocytic activity of feline peripheral blood phagocytes. Further study will be needed to elucidate this phagocytic factor.

  • Foreign culture, introduced by cultural exchange, was modified and accepted into a new form and value system. Culture speaks for the characters of the period, so it is presented by the mutual actions of many factors affecting culture. Religion is the essence of human life and the source of ideas about life, the universe and existence, so they become hidden inside of the structure of culture. Dancing costumes present the process of cultural modification and acceptance more vividly than general costumes. This research shows that, among foreign cultures, it is Buddhism that most influenced Chinese dancing costume. Taoism was the Chinese native religion that played an oppositional role against Buddhism. Taoism was hidden in Chinese dancing costume in every age. Chinese dancing costume changed many times due to the import of exotic styles such as Buddhism that partially replaced the Taoistic tradition. Therefore, it is confirmed that the process of cultural importation of exotic style was different according to the social, historical, and cultural backgrounds of China during the period from the Han to the Sui and Tang dynasties.

  • This research investigates the impacts of information security (IS) culture and management leadership styles on employee's security behaviors (IS policies compliance, IS participation) in financial institutions. This study use the survey data collected from 236 employees of financial institutions. This research shows that IS culture has a positive effect on both behavioral intentions to comply with IS policies and the intentions to actively participate in information security activities. Transactional leadership has a positive impact on the IS policies compliance intentions and to participate in information security activities. In contrast, transformational leadership has a positive impact on the intentions to participate in information security activities, but not on the IS policies compliance intentions.

  • Chinese traditional patterns, which are part of our national precious heritage, have a long history. Tiger culture plays a very important role in folk art. In modern society, it is a symbol of human spirit and morality. The tiger pattern is also a unique traditional pattern in Chinese folklore. From the Spring and Autumn period to modern society, the tiger pattern has evolved in form through thousands of years of development. It is also a representative intangible cultural heritage in contemporary times. It plays a special role in the cultural exchange of different regions, resulting in the generation of the creation of folk art with great local characteristics. Therefore, traditional tiger patterns are an important part of traditional Chinese folk culture and art. In this study, by analyzing the development and evolution history of Chinese traditional tiger patterns, the application methods of Chinese traditional tiger patterns were summarized, the rich cultural connotation, artistic characteristics and application of traditional tiger pattern in modern fashion design were discussed.

  • This study was intended to examine the continuance and transformation of food culture during the enlightenment and Japanese ruling era by analyzing the novel of "Toji". In the novel "Toji", the chaotic political and economic situation is reflected, along with the peoples' hard lives in the latter era of the Choson Dynasty. After the full-fledged invasion of China by the Japanese, the shift to a wartime posture was accompanied by an increased need for food. This led to a rationing and delivery system for rice in the late 1930s. While it was hard for people to obtain even brewer's grains and bean-curd dregs, food distribution officers were well off. Another distinctive feature of the food culture during the enlightenment and Japanese ruling era was that foreign food and recipes were introduced naturally to Korea through the influx of various foreigners. The industry of Choson was held by Japanese monopolistic capital, as a result, Choson had equal to the role as a spending site and was only gradually left destitute. In the Japanese ruling era, there were new type of business including such as patisserie of the types of civilization in the town, and those tempted Korean people. However, the Japanese and pro-Japan collaborators dominated commercial business. Being urbanization through the modernization, it was became patronized fast food in the populous downtown, and the change of industry structure and life style greatly influenced into our food culture. Acceptance the convenient Japanese style fast food such as Udong, pickled radish made was actively accepted with a longing for the advancement civilization. After the enlightenment, many Japanese exchange students went to Tokyo to get advanced civilization and provided urban mood according to their consumption of bread, coffee, Western food, which were considered a part of the elite culture.

  • An anion exchange chromatography was employed for the purification of mouse monoclonal antibodies from ascitic fluid and in vitro cultivation media. After cultivation of hybridomas, Alps 25-3, HCGK, A4W, and KW, producing IgG1, the culture supernatants were harvested by centrifugation, precipitated with 50-60% ammonium sulfate, and dialyzed against 0.025 M Tris-HCI buffer (pH 8.2). Then the dialyzed samples were loaded into a DEAE-Trisacryl M anion exchange column. Monoclonal antibodies bound to the DEAE-Trisacryl M were eluted with 0.025 M Tris-HCI buffer (pH 8.2) containing 30-40 mM NaCl. In ammonium sulfate precipitation, the recovery of the monoclonal antibody was shown to be 90% and 84% from in vitro culture media containing 10% and 2% fetal bovine serum, respectively. On the other hand, the pretreatment by ultrafiltration enhanced the yield up to 91% whereas the purity was lower than that by ammonium sulfate treatment. Subsequently, in the DEAE-Trisacryl M chromatographic separation, the purities and recoveries of all the monoclonal antibodies from both the in vitro culture supernatants and ascitic fluids were 70-80% and 65% respectively. The monoclonal antibody, Alps 25-3 could be further purified with a purity of 95% through an immunoadsorbent chromatography.

  • This main purpose of the study is to identify social network of communicators sharing information on Bokjiro for publicizing welfare policy. This study employs NodeXL pro to understand networks and their role in the social network. The data for social network analysis was collected from Twitter for a week. The result of the analysis shows that the social network of communicators on Bokjiro does not have many nodes. It also has an independent network with high possibility of information distortion. Little communicators have controlling power in information flow in one way of communication. According to the result, it is not effective for marketing strategy of welfare policy in providing online information through Bokjiro. The study suggests that the government should use the transactional approach to marketing based on agent-oriented activity focusing on the exchange relationship between information providers and demanders in an age of networked intelligence.

  • The utilization of horticultural tools in Korea is historically viewed through limited materials. The garlic shown in the birth myth of the Korean nation appears to be the first record of horticultural foods. Only the fragmentary knowledge is available on the production and utilization of horticultural foods during the eras from Old Chosun to the Three States and the Unified Shilla. It seems that mutual exchange of horticultural foods between the Three States and neighbor countries was very active. Kinds of horticultural foods utilized were more variable in the era of Koryo dynasty. The situation on horticultural foods during Chosun dynasty is comparatively well known through published agricultural books and other literatures.
