This paper investigates the relationships among family-friendly culture, intrinsic motivation, team-member exchange(TMX), and creativity in ICT(information & communication technology) company. Also the study investigates the moderator effect of TMX and the mediator effect of intrinsic motivation in the relationships between family-friendly culture and creativity. A structural equation modeling(SEM) was employed to test the hypotheses. Using survey data collected from 229 R&D department and support personnel in ICT company. The main finding of this study was as follows: First, a family-friendly culture had a negative effect on employee creativity. Second, intrinsic motivation had a positive impact on employee creativity. Third, a family-friendly culture had a positive effect on intrinsic motivation. Fourth, intrinsic motivation mediated effect on the relationship between a family-friendly culture and employee creativity. Fifth, the positive relationships between a family-friendly culture and intrinsic motivation were stronger when TMX was high rather than low. In particular, this review concludes with implications for future research, limitations of this study, and practical application.

Production of foreign proteins by transgenic plant cell cultures has several advantages such as post-translational modification, low risk of product contamination and low-cost production and purification. However, target proteins are degraded by extracellular proteases existing in the media. A solution to this problem is the use of perfusion culture and ion exchange chromatography for the application of integrated bioprocess using in situ recovery. With this method, production of human granulocyte-macrophage colony-stimulating factor (hGM-CSF) was investigated in this study. First, optimization of cell concentration during the induction phase for the production of hGM-CSF was examined. As cell concentration increased, the level of hGM-CSF was decreased due to the presence of extracellular proteases. Induction using sugarfree media produced 33% more hGM-CSF. The effects of pH on the binding of hGM-CSF to cationic and anionic exchange resins were also investigated. In terms of stability, optimal pH was found to be 5~7. In the case of using buffer exchange when CM-Sepharose was used as a cationic exchange resin, optimal pH for binding was 4.8 and adsorption yield was 77%. When DEAE-Sepharose was used as an anionic exchange resin, it was 5.5 (74%). Without buffer exchange, optimal pH was 4.6 (84%). From these results, an integrated bioprocess using in situ recovery with simultaneous production and separation of foreign protein in transgenic plant cell suspension cultures was found to be feasible.

In biofloc culture for olive flounder, Paralichthys olivaceus, the possibility of antibiotics treatment was investigated against edwardsiellosis. After inducing edwardsiellosis by immersion in Edwardsiella tarda 1.2 × 10⁵/mL suspension, the survival trends on various biofloc water management and some physiological changes were observed. For biofloc water management, six types of water treatments were carried out, which were no exchange without antibiotics as negative control, the exchange to stored biofloc water, the exchange to stored biofloc water with 20% flow-through, the exchange to fresh biofloc water, half fresh biofloc water and half sea water, and the complete flow-through. There was no significant physicochemical change on water qualities in any type. The exchange to fresh biofloc water was shown the highest survival ratio as 72.3%, and in case of stored biofloc water with 20% flow-through, the survival ratio was also significantly high as 62%. Plasma glucose, cholesterol, total protein, calcium, and magnesium were analyzed as physiological index. Mostly, there was no significant change, but plasma cholesterol showed an initial decrease in low survival group, and an initial increase with high survival group. Consequently, antibiotic treatment against a bacterial disease during biofloc culture is possible as long as the biofloc water management follow along properly.

With the release of the Bitcoin source in 2009, cryptocurrencies are continuously developing and expanding the market. Recently, new applicability is expanding centered on NFT coin and metaverse payment service. In particular, the Central Cryptocurrency Exchange actively supports relay transactions between cryptocurrencies or between traditional fiat currencies and cryptocurrencies. The cryptocurrency trading market based on such a central exchange encouraged speculative factors of cryptocurrencies, strongly arousing speculation and futility of cryptocurrencies. In addition, the central cryptocurrency exchange induces the centralization of users and virtual assets, thereby hindering the decentralization and security enhancement strategies of the block chain. Therefore, this study describes the current status and problems of centrally controlled centralized cryptocurrency exchanges in service, and presents a distributed cryptocurrency exchange modeling strategy and major issues as a decentralization model of the exchange. This research can strengthen the anonymity, decentralization, and autonomy of cryptocurrency based on blockchain.

As of today-half a century has passed after 1945, the liberation from Japanese imperialism-it's significant to introspect our culture. On the one hand our culture has succeeded due to the peculiar history, but on the other hand it hasn't. So to speak, it has gained in Quantity but lost in Quality. There are keen, international competition and exchange in the modern culture. So the Qualitive success of modern design depends on if it had an original character or not. According to Korean rapid industrialization, technological extence, and economic growth, the export has increased greatly, but package design hasn't been match for them. Korean expoters have been meeting with cutthroat competition in world market. Under these circumstances it's very important that we have a real understand and interest in our culture, we strengthen the competitive power of home products with good package design. This is our age of not home market but world market. We live in an age when design wins, so that we have to develop the good design native to Korea. Many designers have proposed their opinions with the characteristic designs, but it has been only a fragmentary and passive method. We must seek for the new method more positively. The effective and proper method resolves itself into the following four points. First, to understand Korean history and culture. Second, to have the exact grip of this economic situation. Third, to promote the national emotion. Fourth, in conclusion, to accord the package design with them. We cannot put off this task to overcome the cultural subordination, to place Korea on a firm cultural basis in the world, and to contribute to the cultural exchange of package design.

Clothing ventilation was investigated using a manikin wearing an impermeable overall under an isothermal condition, in which the ventilation occurred only through the openings. The ventilation volume was estimated by both microenvironment volume and ventilation rate, where, the microenvironment volume was measured by an air subsitution method and the ventilation rate by a trace gas method. Microenvironment volume of the experimental garment was about 21.0 liters. Even though it was certainly affected by the distance from the opening, the ventilation rate was more significantly influenced by the opening area and the shape of air layer in the clothing. The volume of air exchange in the clothing microenvironment was affected greatly by the microenvironment volume and the opening area, and it was different for each part of the body with bigger air exchange volume in the microenvironment of the leg as compared to that of the arm.

Recently, as an enonomic importance of the Eurasian Continent raises, the necessity of east-west connecting ancient transport roads research is increasing. Although domestic research of eastern-western international exchange in the Eurasia is not yet very active, the studies of history, archaeology, art history, folklore, costume history have been advanced steadily. An attention for the exchange through steppe route originated from the interest in Korean folk and Korean culture and the research range is extending to Xiungnu, Kurgan culture as a direct investigation on the remains of Mongolia and Kazakhstan has been achieved constantly. The art history has been leading the research of exchange which is based on desert and oasis. The field research of Iran, Uzbekistan, Azerbaijan, etc progressed in various routes, and the research on diverse topics including Silla's golden culture, transmission of glass, and the Buddhism is improving. Research on the maritime silk road is weaker, compared to other parts. Buddhist and Hindu temples of Southeast Asia attracted some interest to people, but the research should focus on the restoration of sea route and consideration of its meaning. Research of this part is expected to be more activative, as domestic researchers investigate Don Son culture and Sa Huynh culture of Vietnam by themselves. From now on, we should focus on topics that are not directly connected to Korean history, and Korean culture. Because it is also our duty to study and conserve the culture of entire human community.

This study is on the alcohol beverage utensils represented on the Chinese tomb mural paintings of Song, Liao, Jin, and Yuan those countries had foreign exchange with Koryo Dynasty. These mural paintings are distributed in the areas such as Hebei, Henan, Inner mongolia, Shanxi, Shaanxi, Peijing. etc. The Alcohol beverage vessels were classified mainly into storage vessel, pouring vessel, drinking vessel and ladles according to the purpose. The storage vessels of Song, Liao and Jin were called Jiuping, Jingping, Jiuzun as well as Meiping. Pouring vessels are basically one set of Zhuzi, Wenwan and Jiuzhu, or Zhuhu and Zhuwan. On the mural paintings of Yuan Dynasty, Meiping as storage vessels disappear, and a variety of shapes of pouring vessels such as Mayu and Yuhuchunping appear. This trend indirectly indicates the new arrival of distilled liquor, which seems to have affected transition of the alcohol beverage utensils.
