Unconventional natural gas resources are now estimated to be as large as conventional resources. Unconventional natural gas has became an increasingly important source of energy in the world since the start of this century. The factors that drive natural gas demand and supply point more and more to a future in which natural gas plays greater role in the global energy mix. The expansion of using natural gas will be expected in Korea. This research aims to analyze environmental impacts of expansion of unconventional natural gas. This research was carried out for comparative analysis between global energy mix and Korea energy mix, and developed a case that reflect the changed energy mix due to the expansion of unconventional natural gas in Korea. Also this research evaluate the production of air pollutants and the cost of the damage in power generation sector. The results of this research can be summarized as that natural gas portion of future global energy mix (about 25%) is greater than Korea energy mix (about 12%). This research developed a case that replace 10% energy of power generation sector to natural gas in the 6th demand supply program, reflecting the changed energy mix due to the expansion of natural gas use. In that case, air pollutants would be reduced gradually through 2015 to 2027. In detail, carbon dioxide reduces 22 million tons and environmental damage cost reduces 4500 billion won by 2027.

Greek myth is a play of imagination. It represents world with magic eye. The Greek myth of Homer and Hesiod is the story of gods. But it is the world of imagination which was produced to understand the origins and the causes of natural phenomena with the symbolic factors. It is the frame with which we understand the destiny of human beings. As a world of imagination, Myth is not a total fiction but a symbolically revived world with magic eye. Myth is a play which represents the world with imagination. And it is a play which projects new world yet not exists. Myth is the world of free play with reproduction and imagination. Heraclitus elucidated the structure and change of world with the metaphor of play. He tried to define the meaning of being with play. The play is the clue of elucidating the meaning of being. On play the whole world is reflected. He expressed the world has no ultimate end and is changing endlessly. Philosophical speculation understands the world with the metaphor of play. Metaphor is correlated with the philosophical eye which view the world totally. The human beings are happy when they concentrate upon play. The rule of real world doesn't go in the world of play. They have their own rule which goes in the world of play. Ancient mythologists and pre-socratic philosophers dreamed the life free from the restriction of the nature.

In order to locate Kant's concept of the highest good within ethics and the theory of moral religion, it needs to be approached with some qualifications: there are two rough ways to be suggested. The first way is to focus on the concept of the highest good that is explained in terms of the happiness in proportion to a rational being's virtue or to his/her worthiness to be happy. But the happiness determined in the sense outlined above would be (increasingly or decreasingly) changeable according to each one's individual morality-this is what is meant by each one's 'worthiness' here-, and would not be seen as the perfect one. It might even be said that this kind of happiness is possible in a sensible world generally taken, if the existence of God thought of as harmonizing natural phenomena and the moral order is successfully presupposed. The other way is to understand the concept of the highest good literally: in this view, the highest good shows that a rational being's character is completely appropriate to the moral law and for him/her, its corresponding idea, i.e., the perfect happiness, is considered with full justification. But the highest good in the sense sketched above-along with the existence of God and the immortality of the soul-is expected to be realized only in an intelligible world generally taken. This means that it should be appraised as an ideal of the highest good that includes the so-called 'physical happiness' specified in terms of the first way as its element. In this regard, it is seen to be somewhat restricted. Between the two concepts of the highest good already touched upon, the highest good of the possible world would be the one established in terms of the first way. In other words, it is not the highest good in an intelligible world, but the highest good in this world. Of course, it is true that we cannot help but assume the existence of God-a being as higher, as moral, as most holy, and as omnipotent-in order to explain the highest good in this world (namely, in order to establish the possibility of the combination of the happiness and the worthiness). For as long as both morally good acts and the happiness are considered to happen in a natural world, the cause of the nature (i.e., the existence of its creator), that is, God, must be able to be presupposed. In this vein, Kant interprets that most people view that the key of the Bible is to show that the best world which is characterized by an intelligible or heavenly kingdom is also actually feasible in this world. The wish of the people who have the morally good character is that God's kingdom comes and his will is properly achieved in this world. But we cannot know what God really does in order to realize his world in this world. Nonetheless, we are fully aware of what we should do in order to make ourselves a member of his world. It is specified like this: we should do our ethical duties and further proceed to establish an ethical community. Viewed this manner, it is concluded that an ethical community is not a merely ideal thing like the kingdom of the ends, but a human apparatus or institution that exists in this world.

Cancer represent one of the most serious health problems and major causes of death around the world. Many anticancer drugs in clinical use today are natural products or derived from natural sources. Withania somnifera (L.) Dunal is a small shrub widely distributed in many parts of the world including Saudi Arabia. The antiproliferative activities of the methanolic extract of W. somnifera leaves collected from Faifa mountains, southwest Saudi Arabia against MCF-7, HCT116 and HepH2 cell lines were investigated. The extract showed a strong antiproliferative activity against all cell lines with $IC_{50}$ values of 3.35, 2.19 and $1.89{\mu}g/ml$, respectively. Flow cytometry results showed that the extract arrested the cell cycle at S phase, and the increase in the caspase 3 activity suggested that the extract could induce cell apoptosis by a caspase mediated pathway. These results demonstrated that the methanolic extract of W. somnifera leaves collected from Faifa mountains has comparable strong antiproliferative activities to samples collected from different locations.

Lately, the scale of the primary energy consumption in Korea is ranked 10th in the world, and it takes up about 1.9% of the entire energy consumption in the world. And among total energy consumption in Korea, the ratio of the part corresponding to the residence or commercial buildings is about 30.5%. Also, with the increased interest in eco-friendly buildings, the production of eco-friendly building materials consisting of them also increases as well. However, since the process of their production generates much energy consumption, so this is being raised as a social problem. Therefore, this study suggests a method to improve thermal performance by using eco-friendly earth plastering materials and natural materials in order to reduce energy consumption in buildings. The experiment evaluated thermal performance by measuring the external and internal temperature of the curing after the plastering of 1cm in the wooden box of 30cm * 30cm * 30cm. As a result, there was difference in the order of powdered coal, pealite, chaff, and rice straw. Among them, powdered coal indicated excellent thermal performance. This will be the foundational research used to improve interior environment and reduce heating bills.

Arabidopsis is well-known to the world's plant research community as a model plant. Many significant resources and innovative research tools, as well as large bodies of genomic information, have been created and shared by the research community, partly explaining why so many researchers use this small plant for their research. The genome sequence of Arabidopsis was fully characterized by the end of the $20^{th}$ century. Soon afterwards, the Arabidopsis research community began a 10-year international project on the functional genomics of the species. In 2001, at the beginning of the project, the RIKEN BioResource Center (BRC) started its Arabidopsis resource project. The following year, the National BioResource Project was launched, funded by the Japanese government, and the RIKEN BRC was chosen as a core facility for Arabidopsis resource. Seeds of RIKEN Arabidopsis transposon-tagged mutant lines, activation-tagged lines, full-length cDNA over-expresser lines, and natural accessions, as well as RIKEN Arabidopsis full-length cDNA clones and T87 cells, are preserved at RIKEN BRC and distributed around the world. The major resources provided to the research community have been full-length cDNA clones and insertion mutants that are suitable for use in reverse-genetics studies. This paper provides an overview of the Arabidopsis resources made available by RIKEN BRC and examples of research that has been done by users and developers of these resources.

Sequent Calculus is a symmetrical version of the Natural Deduction which Gentzen restructured in 1934, where he presents 'Hauptsatz'. In this thesis, we will examine why the Cut-Elimination Theorem has such an important status in Proof Theory despite of the efficiency of the Cut Rule. Subsequently, the dynamic side of Curry-Howard correspondence which interprets the system of Natural Deduction as 'Simply typed $\lambda$-calculus', so to speak the correspondence of Cut-Elimination and $\beta$-reduction in $\lambda$-calculus, will also be studied. The importance of this correspondence lies in matching the world of program and the world of mathematical proof. Also it guarantees the accuracy of program.

In recent years, the intellectual property rights (IPR) are increasingly becoming trade goods and the subject of international trade negotiations. During the past decades, intellectual properties earned critical importance for economic development in both developed and developing countries. Developed countries, headed by the United States, that recognize the economic value of the IPR in the world market are aggressively seeking for universal protection of IPR throughout the world. Intellectual properties have unique qualities that distinguish them from other tangible goods. Most importantly, they are public goods created on the basis of knowledge and information accumulated throughout human history and shared by different cultures. However, there is a growing tendency that the quality of public goods are being etched away as the property concept in IPR expands. In this paper, I discuss how copyright and patent laws incorporated the concept of property right as natural right to one's intellectual creations in early formation of the laws in Europe. I argue that copyright law and patent law are the historical products resulting from political, economic, and ideological factors interacting in a certain society. A history of copyright and patent points to that the intellectual property rights as natural lights of authors and inventors as argued by developed countries in international disputes, are not universal, but unique historical products. Copyright and patent laws have been shaped and developed as regulatory measures by governments to promote and control industries by providing authors and inventors with monopoly incentives. Since property right was used as a regulatory device it was restricted. This is to enhance the distribution of knowledge and information rather than to ensure the property right as an absolute right.
