Recently, the convergence of knowledge based society and information telecommunication technologies has a rapid impact on politics, economics and various fields. Meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. Meta-analysis, can see the direction and size of the relationship between variables using the concept of the effect size. The factor determining behavioral intention of consumer in e-commerce can say that critically dependent variable. In a predictive factor determining behavioral intention is typical that perceived value and perceived risk. We conducted a meta-analysis and review of between perceived value, perceived risk and behavioral intention on e-commerce researches. This study focused a total of 33 research papers that established causal relationships in between perceived value, risk and behavioral intention on e-commerce published in Korea academic journals during 2000 and 2016. The result of the meta-analysis might be summarized that the effect size in the path from the perceived value to the behavioral intention with the effect size (r = .526), listed an explanatory power of 28%. In addition, it showed that the effect size in the path from perceived risk to the behavioral intention with the effect size (r = -.220), listed a negative explanatory power of 5%. Based on these findings, several theoretical and practical implications were suggested and discussed with the difference from previous researches.

The chemical compositions and lead isotope ratio of Poong-Tag(wind bell) bell excavated from Wanggyeong site, Gyeongju have analyzed by ICP and TIMS. The analysis result of chemical composition of Poong-Tag shows that it consists of 92:4 ratio of Cu:Sn. Other 8 minor elements(Pb, Zn, Fe, Ag, Ni, As, Sb and Co) show the concentration of below 0.2% respectively. This result means that Poong-Tag have made using highly purified Cu and Sn ore. For the study of provenance of raw material with the lead isotope ratio, the origin of the raw material of Poong-Tag can not be presumed owing to beyond the scope. The observation result of microstructure of Poong-Tag show the dendrite structure made through casting process. The chemical composition, microstructure, and lead isotope ratio of Poong-Tag excavated from Wanggyeong site, Gyeongju can be used as fundamental data to compare with other Poong-Tag of different regions and periods.

Icheon Seolbong fortress is located in Saum-dong, Icheon, Gyeonggi-do Province that its date is founded as 4th century of Bakjae dynasty after excavation by Dankook university museum. Excavated artifacts show various kinds such as earthenwares, ceramics, metal artifacts and so on. Especially many iron artifacts were founded in where Bakjae earthenwares were found that it indicates iron artifacts were manufactured in Bakjae Dynasty. From 6 iron sickles, called Beollat and Millet, samples were taken to examine mircostructures and from the results used iron material, shape-forging, steel-making process, heat treatment were investigated. From this late 4th century Bakjae dynasty iron manufacture profess was established. From the result, different treatment were used in different area of the sickles according to the its use. Beollats were quenched in blade and it was used for special purpose that require Intensity. Millats did not have special treatment that it was used to cut rice plant and plant. Used material was steel, steel was previously made by certain steel-making process. It is formed to produce iron ware and the area where intensity is required heat treatment was employed to make it strong. From the investigation it is derived that iron ware manufacture process in Bakjae dynasty is steel making$\rightarrow$shape-forging$\rightarrow$and heat treatment.

The crucibles of Baekje Kingdom from the Ssangbukri Site which were used for glass and metal melting had light brown, grayish blue and grayish brown colored bodies. In thin section, the crucibles contained numerous quartz grains and pottery fragments. The surface was covered with fine grained quartz for thermal resistance. Based on decomposition of mica group minerals and formation of mullite detected by X-ray diffraction analysis, it was inferred that all crucibles have been fired over $1,000^{\circ}C$. It was also found that firing temperature has exceeded $1,100^{\circ}C$ in some crucibles because feldspar was not detected. The maximum temperature was assumed at $1,200^{\circ}C$. The magnetic susceptibility values and geochemical characteristics sorted out the crucibles into two groups that differed from the characteristics of the local soils. This reflected geological setting of the site where the alluvium was formed from two kinds of surrounding rock masses, granite gneiss and biotite granite. However, the local soils had similarities with the crucibles in weathering degree and geochemical behavior of major elements. In consequence, it was considered that the raw clay of the crucibles was supplied from the local area of the site.

In Bongseon-ri site, the central type and the local type of the Baekje tombs co-exist together. Many swords with ring pommel which to regional leaders in Seocheon the Beekje government granted are excavated from these tombs. These represent that the regional leaders were controlled by the Baekje government gradually. Four swords with ring pommel and one simple sword are investigated metallurgically and we seek what swords have a function of weapon or what sword produce for grave goods. The simple sword is made by solid carburizing technology and quenching of heat treatment so it's possibly used as a weapon. In contrast, four swords with ring pommel has little chance of weapon because the blade of swords consists of microstructure that have low hardness and the back of swords don't have microstructure can absorb the shock. The most identical characteristic of the simple sword and swords with ring pommel is that they are possible to classify clearly into practical/non-practical tools. Additionally, according to non-metallic inclusion analysis result of these swords, w$\ddot{u}$stite and glass phase are found together. Thus, it is able to say that reduction method in low temperature is applied during smelting process.

Our world is communicating by digital network that transcends time and space. In such world of rich technology, people are longing for humanity and analog esthetic. 'Art' stimulates analog esthetic and 'design' is a good and easy tool to show personal esthetic preferences. This study is about the convergence of digital and analog art focusing on the researcher's artwork series. The series is derived from series. They are made by cut and deconstructed pieces from the original series. I assembled these pieces into another creation by using graphic editing programs. I looked into the succession cases of art and design collaborations and developed various design products with the assembled artwork images. Through this, I want to communicate more familiarly with the world widely connected to network viewers. There are already many fine artists making their artworks into design products. Collaboration with cultural art and commercial product provides win-win effect to artist, company, and consumer. It also creates innovative products and values. In this study, I try to design products from various fields using my artwork images, and research about how to promote the artist and art products effectively to the world.

This study investigates how 'multi-perspective' can be utilized in animation. For this goal, 1 used the traditional techniques of Korean folk paintings called 'Minhwa.' Most 'Minhwa' works, employ 'multi-perspectives', instead of linear perspective of the Western tradition that has been only taught to students under the formal education system. In Minhwa parts of reality are not only stylized but also fragmented and combined within the same frame. Other common techniques of 'Minhwa' include frontal view, bird's eye view, and inverse-perspective, which are of ien combined in one single work. The purpose of this study is to develop a working principle and practically apply it to , an animation piece based on the Korean folktale of the same title. In doing so, I have proposed a way to reconstruct and revitalize the traditional art form in the age of digital technology and have concluded that 'Multi-perspective' in 'Minhwa' can be utilized in other contents such as animation.'Multi-perspective' in 'Minhwa' is a rich source that has numerous cultural applications.

Similar to the other cultural contents, the character industry is based on the media which acts as the technological background. In fact, the character industry is the process of that a created character accesses to the consumers via media, builds its value and becomes licensed as a brand in the market. Therefore, it is crucial to select the most effective media for the consistence of a character in the market, as well as for construction of a higher brand quality of the character. Today, "Webtoon" might be considered as one of the marketing means which utilizes the Internet media for raising the character as a brand. Webtoon has apparent strength because it can be produced in shorter period and with less expense than through other media. Furthermore, Webtoon can be simply featured by the easiness of two-way communication and transference to another media through it. For these reasons, and according to the result of analyzing some Korean Webtoons, it seems obvious that the most effective media in character marketing is the Internet. In addition to the Internet, the strategic development in the media-mix is also important for establishing a brand of a character. However, the effective media-mix is available only when the character's external identity meets with the trait of its media. For the purpose of learning how the media-mix works when a character reaches for the consumers, a character "Hamataeng" was born and used in the experiment. This study will explain the marketing process through the use of own-created Webtoon and other contents, and suggest the ways to build a brand of a character. In addition, it is also indicated that a media-mixing strategy for transformation and expansion of the character to other media.

This paper is to analyze citizens' consciousness on urban changes, especially focusing on changes in urban environment, spatial structure, and urban planning, of large cities in S. Korea, that is, Seoul, Daejeon, Daegu, and Kwangju in the 1990s. Some significant points can be described as follows. First. The most important factor influencing on the change of urban spatial structure was the expansion of residential area inner and outside of cities promoted by the traditional construction industry, and not development of high-tech industries and their complex or location of multi-national firms which can be emphasized as major factors of new urbanization process of global cities. Secondly, citizens seem to have experienced improvement and deterioration of urban environment simultaneously, emphasizing regulatory environmental policy on the one hand, and recognize the necessity of sustainable urban development within given environmental capacity and restoration of destructed and polluted environment of cities. Thirdly, the building boom of new apartment complex was a major driving force of changing urban spatial structure, but it could neither alleviate a residential gap between the poor and the rich areas nor a relief of traffic congestion. Finally, the urban policy in general was felt somewhat improved by citizens, but not in sectoral details.

The rapid innovation of information and communication technology and its sharp falling prices have brought about the expansion of the Internet, integrating the world as one space under converged space and time. This rapid expansion of the Internet and its application in the economy have spurred the emergence of the digital economy. The Internet has influenced strongly on the changes of not only economic activities but also political, social and cultural activities. In this context, a rapidly increasing Internet expansion renders the rhetoric about the death of distance and about the meaningless of geographical place. However, the development and expansion of Internet induces a growing digital divide among nations and also a spatial inequality in a nation as the supply of the Internet has concentrated towards demand-affluent large cities. A large gap of digital access has been occurred between high income and low income countries according to a measurement of the international digital access index. In a national level, the Internet backbone has been built around large cities which favor a large amount of the Internet demand, and the affordable accessibility of these cities for the Internet services has influenced strongly on the agglomeration of Internet related industries, further inducing the construction and investment of the Internet backbone into large cities as cumulative causation effects. As a result, the expansion of the Internet affects immensely on the changes of spatial structure in a nation resulting in the new spatial phenomena such as centralization, concentration and splintering in the digitalized space-economy.
