Tree of heaven (Ailanthus altissima Swingle) as an invasive alien plant, appeared usually in the disturbed locations such as road-side, incised slope, and trampling path-side. They appeared abundantly in the trampling pathside but they did not appear or were rare in the interior of forest. Density and importance value of tree of heaven were proportionate to the relative light intensity measured according to distance from the trampling path toward forest interior and closely related to the breadth of trampling path as well. They were associated with annual, other exotic species or ruderal plants well. Distributional pattern of mature trees of them in the study area and its surrounding environments implied that they were introduced intentionally. Size class distribution of them showed that they are in expansion and artificial interferences such as, installing physical training space and developing hiking course functioned as trigger factors in their invasion and expansion. The results support the facts known generally in relation to invasion and expansion of the invasive alien plants. In this viewpoint, we suggest a management plan that applies ecological restoration principles to address ecosystems infected with tree of heaven by restoring the integral feature of the degraded nature and conserving the remained nature more thoroughly.

The basic framework of traditional Korean clothing construction consists of circle, square and triangle. This composition principle has been presumed to be associated with the Cheonbu concept of the Dangun era wherein nature and human being are considered united. The Cheonbu concept is represented by circle, square and triangle which constitute Cheonbuin, the images and meanings of heaven. It contains profound philosophy wherein a circle symbolizes heaven and represents number one, a square symbolizes earth and represents the number two, and a triangle symbolizes human beings and represents the number three. Circles, squares and triangles have been used as various symbolic meanings both in the east and west and constitute the framework of Hanbok construction while connoting the Cheonbu concept and symbolism of the Cosmo-tree. From this point of view, the unity of human beings and heaven in Cheonbugyeong is symbolically inherent in Hanbok. Therefore, Hanbok with the basic framework of circles, squares and triangles can be considered a positive creation that created a composition principle of body-nature-clothing.

The tree of heaven naturalized plant grows in the various habitats of the city. The principal reason is that it is reproduced not only through sexual reproduction but through asexual reproduction. By the spreading of sucker and a bud appearance of the seed it forms a group easily inside the city habitat. The distribution of seed and spreading of the seedlings of the tree of heaven were investigated like the followings. As the result of the sexual reproduction by the seed and hangs in cluster farm, 350 individuals are germinated at the Namsan the best environment, and 50 individuals at Toegyewon Rotary These seeds are dispersed by the effect of wind and geographical factor. Because the northwest wind is blowing mainly from late autumn to early spring, it is dispersed in the south. In Toegyewon Rotary, a slant site, is dispersed mainly by down the site. Compared with width of crown, the seedling of a seed germination are distributed outside more than inside the crown and the seed is spreaded until the maximum 7.5 times of crown width at the investigated area. 1 year seedlings appeared as a group at the place of 2-4 times of the crown (in 20m from the crown, 75% distribution). Considering the distribution by the seed scattering of the tree of heaven, there is a possibility of sudden individual increase even in the deteriorated city environment. So this possibility shows that we need to consider the protection of the city soil, and the species variety decrease resulted from the successful competition to the other species.

The purpose of this research is to find out the role of shaman's costume in Yakut Yukachir Goldi. The results are as follows: 1. Yakut shaman's costumes are decorated by their worship symbols made from metals-wild ducks crucian carps diving beetles and fishes. They believe that these costumes help shamans to travel the heaven underwater or underground systems to collect wanted infor-mation transforming them into the shape of decorated animals. 2. Yukachir shaman's costumes are decorated by symbolized cross medals in the shape of birds and human designed backbone which give shamans much power and many different kinds of medals and tassels representing all sorts and conditions of shaman's power. They consider their cstumes as feather and believe they give them new power and make them to fly anywhere they want. 3. Goldi shaman's costumes have paintings of animal guradians-leopards tigers bears birds snakes lizards and so on. Birds represents freedom of the spirit and eternity. snakes represents rebirth and immorality and lizards represents the trees of underground the earth and the lifetrees of the heaven. Shamans ascend through th holy tree to th heaven and to the world of underground in a comatose condition. Shaman costume itself plays the role of the spiritual safeguard. Wearing their costume shaman get all animal's supernatural authority and power. This makes the shaman to contact with the spirit and to travel the heaven and the under-ground world.

Plato's philosophical importance in western thinking history cannot be understated. Especially his dichotomy system became common to the European traditions of philosophical and scientific discourses by assigning principal value to the presence that is opposed to the absence. Since the ancient Greeks, the concept of presence has been expressed itself in number of ways such as God, Truth, Logos, and center. Derrida called this European thinking "the metaphysics of presence." In order to analyze logocentrism also called the metaphysics of presence in No Telephone to Heaven, I used the term, paralogy that Aristotle did not accept as rules of argumentation but that Lyotard revived it positively as the principle of reason. Lyotard's incredulity towards rationalist theory of modernism is that knowledge can never be certain. Without any ultimate validity, certainty is impossible. Nevertheless, as Fanon said, the colonial world is dominated with a traditional Manichaean world. As a result what remains to the colonized to establish their identities is that of an armed struggle towards the colonizer even though they know it results in the vicious circle of hatred endlessly. Cliff attempted to show this message in her text through the tragic heroine, Clare Savage. Cliff's another critique of modernism's rationalism is shown through the ambiguous sexuality of Harry/Harriot. In this novel, gender plays also a central role by questioning the traditional binary system of sexuality. In this paper, I deconstructed this traditional gender system in terms of Bulter's concept of performitivity. This study will give the text another layer of deconstructive interpretation echoing with the proverb, one tree cannot make a forest.

Hierophany, according to Mircea Eliade, is a natural manifestation of the initial sacred. Through hierophany, profane objects and sites transform their qualities and then they themselves become sacred. People in traditional societies, in an attempt to reenact the initial hierophany, tried to perform consecrating rituals to replicate the first moment of the initial hierophany, at the same time and site. This article focuses on the concrete sites of hierophany. In ancient China, we can see specific sites that manifest the sacred such as Kunlun(崑崙), Jianmu(建木) and zongmiao(宗廟). Kunlun has the characteristics as the Cosmic Mountain that is the realm of the gods that tiandi(天帝) built as his center on the Earth, and it bridges Heaven and Earth. Jianmu joins Heaven, Earth, and the underworld like a Cosmic Tree or Pillar. It can be stated that zongmiao, the royal ancestral temple, functions as the Center of the World, the axis mundi, in which religious human beings express their desire to live in a sacred site, and in which they can regain their initial purity of spirits by communicating with the gods and ancestors. These three are the sites of manifestation of the sacred in China.

Objective : Heavenly stems and Earthly branches is a tool used for understanding the virtue of Yin Yang and Five elements. Korean medicine understands the changes in Wuyun through the Ten Heavenly stems, and understand the changes of Liuqi through the Twelve Earthly branches. An accurate understanding of the definitions of Heavenly Stems and Earthly branches and the concept of each of the 10 stems is of vital importance. Method : The paper first reviews the origin, history, and significance of the Heavenly stems and Earthly branches before studying the definitions of the stems and branches as laid out in the works of Yu Onseo, Lee Samun, and Han Dongseok. The paper then reviewed the concept of the each of the ten stems through researching the texts of Seoulmunhaeja, the annotations of the four great Seolmuns, and the texts of Jeongyeokwonui. Result & Conclusion : Heavenly stems and Earthly branches have been in use since more than 6,000 years ago. The central numbers in the changes of Heaven and Earth are five and six. Each number functions with duality, yin and yang, meaning there are ten Heavenly numbers ($5{\times}2=10$) and 12 Earthly numbers ($6{\times}2=12$) which oversees all of the cosmic changes. Stems become the body and signifies water. Branches become the use and signifies divided fire. The meanings of the letters Gab Eul Byeong Jeong Mu Gi Gyeong Sin Im Gye originate from the one year life of a tree which grows, bears fruits, processes Yang qi, and awaits for the next spring. The reason a tree is used is because there is nothing better in studying in detail the changes of a living being through a year.

We investigated the enect of $O_3$ on the photosynthetic characteristics of tree of heaven (Ailanthus altissima) that is naturalized plant and used as restoration plant for contaminated area. Two-year-old seedlings were planted to pots and transferred into closed $O_3$ chamber. Photosynthetic pigments contents and photosynthetic characteristics were measured every three weeks under 100 pub $O_3$ fumigation. There was no visible foliar injury by $O_3$ exposure and contents of photosynthetic pigments did not show significant differences between control and $O_3$-treated seedlings. Also there were no significant differences in stomatal conductance, and water use efficiency. But photosynthetic rate and apparent quantum yield (AQY) of $O_3$ treated seedlings were reduced after nine weeks of ozone fumigation. In addition, the reduction of carboxylation efficiency and photorespiration were observed in the leave of $O_3$ treated seedlings after six weeks. In accordance with our result, carbon fixation system of A. altissima was most sensitive to $O_3$ stress to evaluate physiological damage induced by $O_3$.

In AI research Go is regarded as the most challenging board game due to the positional evaluation difficulty and the huge branching factor. MCTS is an exciting breakthrough to overcome these problems. The idea behind AlphaGo was to estimate the winning rate of a given position and then to lead deeper search for finding the best promising move. In this paper, using non-strategic MCTS we verified the fact that most pro players regard the best first move as Tengen (Origin of heaven) in $9{\times}9$ Go is correct. We also compared the average winning rates of the most popular first moves.

Throughout analyzing and construing the words, contexts, and expressive languages used for depicting the pine tree in the novel "Honbul" written by Choi, Myung-Hee the symbolism of the pine and folksy languages used for scenery can be condensed as written below: First, it is explicit that the scenery-words for illustrating the pine tree in "Honbul" are emerged through diverse means methods and expressions. Namely, the reference forms of the pine tree and the expressive means of utilizing words portrays the use of the pine are various and subdivided. Second, the scenery-words found in vocabularies and the contexts of "Honbul" imply various symbolic representation. They not only perform to describe inherent image and symbolism of the pine, but they work for reifying the image of "Honbul" in the narrative structure in "Honbul" as being intrinsic scenery-word. Third, the scenery-words used for expressing aesthetics emerge as synesthetic expressions through the linear beauty and the texture of the pine as well as through five-senses. Forth, on the basis of the inherent symbolism and the image of the pine, the landscape of the background described in "Honbul" deems as a symbolic backdrop. As with then narrative structure of the novel, the pine tree performs as a mediation of the heaven and the earth, god and man, as well as the sacred and the secular. Fifth, scenery-words used for depicting the pine tree are a symbol that represents the spirit and emotion of the character in the novel. Moreover, it is a tool for pursuing the personification of the nature, the deification of the object, and the cosmos of the space. It is also utilized as a device that definitize the ideational image applied to express the landscape of the background of the novel. As mentioned above, the expressions, vocabularies and textures about pine tree represented from "Honbul" are expected to be the beginning of understanding the landscape-images and landscape-languages of pine in not only the setting for this novels, Namwon but also the entire districts of Korea.
