The purpose of this study is to ascertain the design element in traditional palaces of Korea, China and Japan. It takes threesteps to proceed this study. Firstly, it needs to be established the analysis framework from the documents. In second step, the design elements - the form, the material, the pattern and the color - should be collected and investigated through the observation of the actual traditional palaces the Changduckung, the Forbidden City, the Nijo castle. The third step is the analysis of the results of the investigation of the design elements from step two. To sum up similarities and dissimilarities among the design element in traditional palaces of Korea, China and Japan is as the following It is to be noticed that the mainly common characteristics of the artistic design are 'naturalism', 'harmonious ideas' and 'confucianism'. But the representation style of the design element is differed from the country. : The typical features of China are symmetry, glassy surface by artificial process, the meandered curve, the magnificent pattern and the constrable color. In Japan, the mathematical asymmetry, made-up rough surface by artificial skill, decorativepattern with abbreviation and achromatic color are important feature of the design element. While the major features of Korean design element are asymmetrical balance with nature, rough surface by natural process, moderate pattern and harmonious color.

It is estimated that over 80% of deer antlers produced in the world are consumed in Korea. However, mislabeling or fraudulent replacement of costly antlers with cheaper ones is one of the most common problems in the domestic antler market. Therefore, there is a great need for the development of technology to identify species of antlers. This study was carried out to develop an accurate and reliable method for the identification and authentication of species or subspecies of antlers using DNA sequence analysis and comparison of mitochondrial cytochrome band D-loop region genes among antlers of five deer species, Cervus elaphus sibericus, Cervus elaphus canadensis, Cervus nippon, Cervus elaphus bactrianus and Rangifer tarandus. A variable region of cytochrome band D-loop genes was amplified using PCR with specifically designed primers and sequenced directly. The cytochrome band D-loop region genes showed different DNA sequences between the species of antlers and thus it is possible to differentiate between species on the basis of sequence variation. To distinguish between reindeer (Rangifer tarandus) antlers and other deer antlers, PCR amplicons of the cytochrome b gene were digested with the restriction enzymes NlaIV and TaqI, respectively, which generates a species-specific DNA profile of the reindeer. In addition, samples of 32 sliced antlers labeled Cervus elaphus sibericus from commercial markets were collected randomly and the mt DNA D-loop region of these antler samples was sequenced. Among the antler samples investigated, only 62.5% were from Cervus elaphus sibericus, and others were from Cervus elaphus bactrianus (25.0%), elk (Cervus elaphus canadensis) and reindeer (Rangifer tarandus). Our results suggest that DNA sequencing of mt DNA and PCR-RFLP methods using NlaIV and TaqI enzymes are useful for the identification and discrimination of deer antler species by routine analysis.

The cultural contents industries have moved closer to the centre of the economic action in many countries and across much of the world. For this reason, the concern with the development of glocal cultural contents has also been growing. According to Goldman Sock's BRICs report, Indian economy will be the engine of global economy with China. In addition, India will be a new blue chip country for large consumer market of cultual contents. The most important point for the development of glocal cultural contents is a systematic and in-depth analysis of other culture. India is a complex and multicultural country compared with Korea which is a nation-state. Therefore, this paper is intended as an understanding about India appropriately and suggestion for a strategy to enter cultural industry in India. As the purpose of this paper is concerned, we will take a close look at 9 Indian culture codes which can be classified into three main groups: 1) political, social and cultural codes 2) economic codes 3) cultural contents codes. Firstly, political, social and cultural codes are i) consistent democracy and saving common people, ii) authoritarianism which appears an innate respect for authority of India, iii) Collective-individualism which represents collectivist and individualistic tendency, iv) life-religion, v) carpe diem. Secondly, economic culture codes are vi) 1.2billion Indian people's God which represents money and vii) practical purchase which stands for a reasonable choice of buying products. Lastly, viii) Masala movie and ix) happy ending that is the most popular theme of Masala movies are explained in the context of cultural content codes. In conclusion, 3 interesting cases , , will be examined in detail. From what has been discussed above, we suggest oversea expansion strategy based on these case studies. Eventually, what is important is to understand what Indian society is, how Indian society works and what contents Indian prefers.

This paper analyzes the changes in financial reform during the Kim Jong-un era based on North Korean literature. We find that North Korea has systematically and functionally separated the central bank from commercial banks since the Kim Jong-un era began. In addition, enterprises have been allowed to withdraw cash from bank accounts and make inter-enterprise cash payments. In other words, nowadays non-cash currencies with passive money can partially serve as active money with purchasing power. With the systematic and functional separation of the central bank and the commercial bank, the issuance of the central bank changed to a money supply method through the commercial bank, and changes in the currency distribution structure have allowed commercial bank's credit creation function to be implemented. This means that the banking system and the monetary·payment system of the socialist planned economy are changing in the way of the market economy. Reforms in the financial sector are believed to have been necessary to support changes in the economic system and to restore the function of the public financial sector. These changes have progressed in terms of the level of reform, but they are still considered similar to the period of the former Soviet Union's Perestroika or to the early period of China's reform and opening. Although North Korea's financial reform is superior in terms of enacting the banking law, it is insufficient in terms of realizing the functions of commercial banks. In addition, it is assessed that institutional constraints such as maintaining a planned economy, and the lack of confidence in public finances limit the effectiveness and development of the financial system. It should be noted that these results are based on literature published in North Korea. In other words, there is a limit in the fact that such recent changes have been carried out on a trial basis in some areas, or have been carried out in a full-scale manner with a blueprint, since Kim Jong-un's inauguration.

In the energy-climate era, pollution emissions from port activities have a significant issue in international shipping and port community. Thus international organization such as IMO and developed countries are seeking to develop various reduction strategies against air pollution. However Korea has recently conducted several studies concerning air pollution in port industry. The main purpose of the paper is to suggest emission reduction strategies for bulk terminal in Port of Incheon, which handles large amount bulk cargoes as a gateway for the metropolitan area. For this aim, the clean air strategies of the world major ports were considered and air pollution reduction strategies were suggested. The main findings of this paper are as follows. First, the emission reduction strategies for container terminal are should be integrated based on technologies changes, operational changes and market-based measures. Second, the emission reduction strategies for bulk terminal can be effective when use innovative measures during loading, unloading and storage process such as telescopic cascade trimming chute, snake sandwich equipment, dry fog system and dome structure. Finally, investigation on actual conditions of air pollution in Korean ports and development of environmental evaluation scheme for persisting monitoring should be conducted.

The construction of Incheon International Airport(IIA) was planned in order to meet the national air transport demand which has been rapidly increased, and to be a major hub airport in Northeast Asia. However, it is inevitable to compete with Japanese airports because Japanese government also planned to expand greatly the airport capacity in Tokyo area and Kansai Airport in Osaka area. Since a hub airport should have convenient connecting flights to spoke cities, it is required for IIA to have plenty of short-haul flights to the cities around Seoul, for example, to the cities in East China, Japan and other East Asian countries. IIA authority and Korean national air carriers should coordinate to develop air transport demand for short-haul international route and establish efficient hub-spoke flight schedules. This would be a essential precondition to function as a hinterland hub in Northeast Asia. Reflecting the geographical position, the function as a hourglass hub could be possible, if IIA is utilised by major airlines as a bridge to connect passengers between cities in Southeast Asia and 'cities in North America. To be a successful hourglass hub, the Korean national carriers must try to engage in the joint operations or the alliances with the major airlines of Southeastern countries or North American countries. All of these could be accomplished through the cooperation among government, airport and national air carriers.

분자단계에서 천연소재 유래 다당체는 면역 세포 표면(예, 대식세포)에 있는 한가지 또는 여러가지 수용체(${\beta}$-glucan 수용체, mannose 수용체, complement 수용체 3, Toll-like 수용체, scavenger 수용체)와 면역 반응을 시작하기 위하여 결합할 수 있고, 그 후에 신호전달을 위하여 cytokine과 second messenger($Ca^{2+}$, cAMP, cGMP, NO 등등)들을 생성한다. 그 결과로 선천면역과 적응면역을 유도하여 다양한 질환에 영향을 미친다. 추가적으로 다당체들의 면역조절은 신경내분비 체계의 조절과도 연관되어 있다. 최근 수많은 천연소재유래 다당체의 생리활성에 관한 연구가 진행되고 있다. 다양한 연구를 통해 정확한 약효, 낮은 독성과 부작용을 가진 일단의 다당체가 발견되어 현재 임상에서 암 치료에도 사용되고 있다. 이러한 사실들은 면역증진 다당체들이 항 종양치료를 위한 새로운 치료제로서 큰 시장을 개척할 수 있다는 가능성을 보여주고 있다. 이러한 사실에도 불구하고 현재 다당체에 대한 연구는 다음과 같은 취약점을 내포하고 있다. 첫째 다당체의 생리활성에 대한 정해진 비교기준이 없다. 특별히 임상 환경에서는 이러한 연구들이 중국, 일본, 한국과 일부 다른 동양국가들에 국한되어 있어 유럽이나 미국에서의 연구 자료가 결여되어있다. 둘째 현재 연구에 사용되고 있는 대다수의 천연소재 유래 다당체는 순수한 다당체가 아닌 천연 그대로의 것을 사용하고 있어 소재로부터 유래하는 다른 활성성분에 의해 쉽게 영향을 받을 수 있어 순수 다당체가 면역체계에 어떠한 역할을 수행하는지 진단하는데 어려움이 있다. 셋째 면역조절 경로에서 다당체의 정확한 신호전달 경로가 아직 정확하게 밝혀지지 않았고, 또한 동물과 임상실험에서 다당체가 작용하는 수용체 및 신호전달 경로에 대한 상반되는 결과가 발표되고 있기도 하다. 따라서 다당체의 면역조절활성에 대한 연구에 있어 다음과 같은 점들에 주목해야 할 필요가 있다. 첫째 다당체의 구조와 활성간의 상관관계를 밝혀야 할 것이다. 특히 다당체의 세부 구조 및 활성 부위를 밝혀낸다면 분자수준의 면역조절 기작을 명확히 하는데 도움을 줄 수 있을 것이다. 이러한 정보를 확보할 수 있다면 다당체의 구조를 변형시켜 활성을 증진시킬 수 있을 것이며, 또한 활성이 증가된 다당체를 합성하는 일도 가능해 질 것으로 예상된다. 마지막으로 ${\beta}$-glucan과 lentinan과 같은 정제된 다당체의 연구를 지속적으로 수행하여 효과적인 동물실험 및 임상실험 protocol을 확보하고 연구결과들에 대한 database를 구축해야 할 필요가 있다. 이러한 노력들이 성공적으로 수행된다면 천연소재유래 다당체들이 가까운 장래에 암 치료를 포함한 다양한 질병에 적용 가능한 새로운 면역조절제로 사용될 수 있을 것이다.

Since the late 20th century, due to the globalization of markets and the rapid developments of information and communication technologies, the world has entered into the age of fierce competition. With their abundant low-cost labor, former communist countries such as China, Russia and East Europe and former low-developed countries such as India and Brazil have received foreign investments from major industrial companies. Thus, there are no other alternatives remained for Korea and OECD countries other than moving the industrial economies to the knowledge based innovation systems. In the knowledge based innovation systems, economic developments and employments of regions and nations depend solely on companies situated in their territories. In this article, after reviewing the current state of technological based innovation small firms in korea, we provide a theoretical framework to promote the level of technology based innovation and entrepreneurship. The theoretical framework for analysis and policy suggestions is based on the Schumpeter's value system model that consist of supply factors, demand factors, and supporting institutions. In order to create more innovative small businesses, we insist on the followings. First, more R&D and innovation activities related with promising new technologies should be performed. Second, more R&D funds for technological innovation small companies should be provided from governments. Third, more M&A transactions and technology transactions should be marketed freely and competitively. Fourth, more business incubating services and venture capital services should be provided. Fifth, entrepreneurship and innovation culture should be popular and institutionized among people.

The dried root of Angelica species is used in traditional Chinese medicine in East Asia, particularly in Korea, China and Japan. Since the plant origin differs in these countries, they are often misused or adulterated in the commercial markets, resulting in distrust among the consumers. Enormous efforts have therefore been focused to distinguish the origin for the Angelica genus, by using morphological or cytogenetical analyses, and chemical markers based on biochemical analyses of secondary metabolites. DNA is considerably stable against different cultivation conditions, and to treatment and processing after harvesting of plants. Hence, several researches have been filed for the development of molecular markers, based on the single nucleotide polymorphisms in specific regions of DNA. However, there are several obstacles for application in the commercial markets, concerning the reproducibility, accuracy, sensitivity, and rapidity of these tests. In this review, we summarize the research achievements that help classify the origin of Angelica species, in particular, Angelica gigas Nakai. A. sinensis(oliv.) Diels, A. acutiloba Kitag., and A. acutiloba var. sugiyamae Hikino. Further researches are required for practical applications.

The key for the commercial deployment of IGCC power plants or chemical (methanol, dimethyl ether, etc.) production plants based on coal gasification is their economic advantage over plants producing electricity or chemicals from crude oil or natural gas. The better economy of coal gasification based plants can be obtained by co-production of electricity and chemicals. In this study, we carried out the economic feasibility analysis on the process of co-producing electricity and DME (dimethyl ether) using coal gasification. The plant's capacity was 250 MW electric and DME production of 300,000 ton per year. Assuming that the sales price of DME is 500,000 won/ton, the production cost of electricity is in the range of 33~58% of 150.69 won/kwh which is the average of SMP (system marginal price) in 2013, Korea. At present, the sales price of DME in China is approximately 900,000 won/ton. Therefore, there are more potential for lowering the price of co-produced electricity when comparing that from IGCC only. Since the co-production system can not only use the coal gasifier and the gas purification process as a common facility but also can control production rates of electricity and DME depending on the market demand, the production cost of electricity and DME can be significantly reduced compared to the process of producing electricity or DME separately.
