It works as intermediation of communication of publics these days. Since 20 century, We, Koreans, have established new chaotic multi culture with traditional Korean culture and other different culture from everywhere. Meanwhile, we occupied the most powerful semi-conduct and IT indusry. Within those circumstance, people feel very confused in political, cultural and social aspect. The society armed with economy and popularization promotes material satisfaction with this potential possibility of anonymous masses. However, it results to cause loneliness, isolation, alienation, anonymity, non individuality and commodity of culture. In my work, such phenomenon reveals through human character in a city. People are exposed culture of consumption and surrounded and tempted by all those artificial and superficial atmosphere. Human are possessed and exposed to attractive products and visual images. Finally they make themselves stuck in their case of this world. People lose their own identify and shape of bodies. That is our portrait, who are living this moment. Also, this is a symbol that destroys this modern society. As a result, 1 consider such aspects through those elements above to think how to keep and rethink our identity and what to do for this world.

In an attempt to establish the mass proliferation system, Eucalyptus pellita, a 5-year-old plus tree, was cultured with three different culture types in 1L vessels: solid culture without ventilation (conventional culture), liquid culture without ventilation and open-type liquid culture with forced ventilation. Then the culture scale was subsequently increased from 1L to 10L in vessel volume. After 4 weeks of 1L-scale culture, the best growth was obtained by culturing plantlets on open-type liquid culture, suggesting that the in vitro plantlets growth can be enhanced by liquid medium and ventilation. In open-type large scale culture in 10L vessel, plantlets growth resulted in a 370% increase in the number of nodes, 3.6 times increase in leaf expansion, and 3.3 times increase in shoot length, while the conventional culture suppressed shoot growth due to the callusing on the leaves and lack of $CO_2$. The results indicated that the open-type large scale culture system was effective for enhancing productivity by improving growth of the plantlets in clonally proliferated plus tree, Eucalyptus pellita.

The proteoglycan, intracellular and extracellular, extracted from the liquid culture of Phellinus igniarius were purified and characterized. The mycelial productivity was proved to be better in shaking culture compared to standing culture. The productivity of intracellular proteoglycan of Phellinus igniarius appeared to be similar in two culturing methods. The standing culture of Phellinus igniarius produced 6 times as much extracellular proteoglycan compared to shaking culture. The proteoglycan were purified to a single peak by ion exchange chromatography(DEAE-cellulose) followed by gel filtration(Sepharose 2B). PIEPDG contained 79.0% total sugar and 7.2% protein. PIEPAG contained 56.7% total sugar and 40.8% protein. PIIPDG contained 64.8% total sugar and 17.4% protein. PIIPAG contained 56.9% total sugar and 41.5%n protein. The molecular weights of all the fractions were estimated to be above 100,000, from 134KDa of PIEPDG to 560 KDa of PIEPAG. The results of sugar analysis by HPLC showed that PIEPDG contains glucose only. The sugar part of PIIPDG and PIIPAG were consisted of glucose and inositol. The PIEPAG contained three kinds of monosaccharides, glucose, fructose and inositol.

The Paekrogdam summit crater area, Mt. Halla, Jeju Island, Korea, composed of Paekrogdam trachyte, Paekrogdam trachybasalt, and Manseidongsan conglomerate in ascending order. Joint systems show concentric and radial patterns around the summit crate wall. The Paekrogdam crater is a summit crater lake which erupted the tuffs, scorias and lava flows of Paekrogdam trachybasalt after the emplaceent of Paekrogdam trachyte dome. SiO$_2$ contents of mafic and felsic lavas are respectively, 48.0∼53.7 wt.％ and 60.7∼67.4 wt.%, reflecting bimodal volcanism. And lavas with SiO$_2$ between 53.7 wt.% and 60.7 wt.％ are not found. According to TAS diagram and K$_2$O-Na$_2$O diagram, the volcanic rocks belong to the normal alkaline rock series of alkali basalt-trachybasalt-basaltic trachyandesite and trachyte association. Oxide vs. MgO diagrams represent that the mafic lavas fractionated with crystallization of olivine, clinopyroxene, magnetite and ilmenite and felsic trachyte of plagioclase and apatite. The characteristics of trace elements and REEs shows that primary magma for the trachybasalt magma would have been derived from partial melting of garnet peridotite mantle. In the discrimination diagrams, the volcanic rocks are plotted at the region of within plate basalt (WPB).

Palaces of a country can be representative aggregate of the culture and arts of the country. Palaces were used not only as a living place to protect kings and royal families and to live cultural lives, but also a political place to govern the country. Kings in Choseon founded the country on the Sung Confucianism, their philosophical background. They built Bangji and Wondo as constant reminders of their philosophy. Bangji is the most apparent characteristic in the palace gardens of the Choseon Dynasty. Finding out the original form of Jidang, restoring the original and passing it on to future generations can be passing on the spiritual culture of our ancestors. This study is done to find out or locate well preserved Jidang, transformed Jidang and lost Jidang in Changdeokgung, which is the best conserved palace of Choseon. This study is composed of Jidang which has been kept in its original state, transformed Jidang, locating lost Jidang and Jidnang which has been unearthed. The total number of Donggwoldo's Jidangs is 17; those that are kept in their original state, 4; transformed Jidangs, 5; Jidangs that were lost and have been located, 8; and newly appeared Jidangs, 2. From the results, opinions on restoration are presented. This study can be a small drop in the thin stream of tradition passing onto future generations in this world where knowledge and information are transported momentarily and the classification of culture and border is mixed, yielding vagueness.

This study is to describe the meaning of associations at $5{\cdot}18$-related photographic portrait phenomenologically. Referent in the photography arouses different and unique type of associations. Moreover, it appears differently emotional experience by the associations. Therefore, the purpose of this study is to describe types of associations and emotional experience about referents gained through $5{\cdot}18$ photography and to construct the meaning. It is based on concepts of primordial associations discussing in the phenomenology but this study was described the meaning of $5{\cdot}18$ the May 18th democratic uprising focusing on types of associations and meanings derived by direct experience from photography. According to this result, the viewpoint of $5{\cdot}18$ Democracy Movement approaches from objective academic system or cannot be withdrew as dynamics of the political ideology. It is that the fundamental and impulsive emotions from each individual who participated in the movement are affected. The fundament of the May 18th democratic uprising is based on their basis of life and the will to primitive power of a love & affective community.

Since the Hwang scandal, the South Korean state has expressed often-conflicting interests of encouraging stem cell research and the IVF industry to save the country and introducing the ethical regulation in conformity with "Global Standard." As the tightening ethical regulation of stem cell research has enervated the field of human Embryonic stem cell(hESC) research, somatic stem cells (re-)emerged as an alternative savior that could rescue the future of research communities, bio-industry, practicing doctors, patients and the nation itself from the crisis. The recent literature on Korean biotechnology, however, mainly focus on hESC and relatively little attention has been given to the rapidly growing field of research on somatic stem cells like hematopoietic stem cells(HSCs) or Adipose derived stem cells(ASCs). While the hESC therapy is often regarded as experimental and ethically controversial, the HSCs or Mesenchymal stem cell(MSC) therapies have already made their ways into people's everyday life through market without much public discussion. Many ordinary people in South Korea are familiar with the story of patients who survived leukemia with the HSCs treatment; the number of doctors who are actively marketing the ASCs therapies is on the rapid increase; the concept of cosmetic products made from ASCs is gaining popularity among consumers. In this context, this article argues that the current ethical debates solely focusing on hESC or on the state policy and research regulation are too limiting to fully illuminate the politics of stem cell technologies in South Korea.

Integrated concepts that are broad enough to embrace facts, principles, laws, and concepts of multiple disciplines could become the core of integrated education. Integrated concept-centered education enables effective and practical learning. In this study, the Delphi Method was implemented targeting experts in science (physics, life science, chemistry, and earth science) and humanities (history, geology, economics, ethics, and politics) to find out the integrated concept that can be used to design the concept-centered integrated education in the Republic of Korea. 124 experts participated in this survey. Delphi survey was conducted for three rounds. In the first round, an open questionnaire was given to experts to collect feasible integrated concepts in each major field. Then, in the second round experts were asked to select integrated concepts that could be used practically in the field of their major. In the third round, the integrated concept with selection frequency over medium value were given. They were asked to evaluate the applicability of integrated concepts by using the Likert-scale questionnaire. Through this process, content validity was analyzed. As a result, five integrated concepts (change, interaction, space-time, energy, and equilibrium) were selected for the inter-science integration. And thirteen integrated concepts (conflict, community, relationship, structure, power, diversity, culture, change, society, interaction, freedom, justice, and equality) were chosen for the inter-humanities integration. Finally, for the science-humanities integration, seven integrated concepts (structure, diversity, change, interaction, cycle, system, and environment) were determined.

To overcome the low mechanical strength and corrosion behavior of a carbon steel canister at high temperature condition of a deep borehole, SiC ceramics were studied as an alternative material for the disposal canister. In this paper, a design concept for a SiC canister, along with an outer stainless steel container, was proposed, and its manufacturing feasibility was tested by fabricating several 1/3 scale canisters. The proposed canister can contain one PWR assembly. The outer container was also prepared for the string formation of SiC canisters. Thermal conductivity was measured for the SiC canister. The canister had a good thermal conductivity of above $70W{\cdot}m^{-1}{\cdot}K^{-1}$ at $100^{\circ}C$. The structural stability was checked under KURT environment, and it was found that the SiC ceramics did not exhibit any change for the 3 year corrosion test at $70^{\circ}C$. Therefore, it was concluded that SiC ceramics could be a good alternative to carbon steel in application to deep borehole disposal canisters.
