This study investigates the retention of Japanese as a second language in Korean elders' Japanese, which has been in a frozen state since 1945. Transcripts of conversations with young and middle-aged Japanese native speakers and questionnaires were used in the research. The following conclusions regarding aspect of Japanese existences were found as a result of this study: (1)In the case of the animate predicate, the dialect form ORU is the most frequently used. (2)Judging from the degree of contact with Japanese and their current Japanese ability, they use it together with ARU in lower than middle group, but use only ARU at the lowest group. (3)ORU, acquired from Japanese teachers, is often used to refer to teachers, but is neutral in formality. (4)The retention of ORU and the convergence to ARU are assumed to have occurred from 1945 until the present. (5)It is observed that ‘the fossilization of ARU’, ‘the cognitive linguistic reconstruction of RU-forms’ and ‘the use of ARU by L1(Korean) interference’ are the linguistic factors that brought about the retention of a system of Japanese existences.

Building on the readings of Yeats’s esoteric poems, essays, and A Vision, I poses to rethink the ethical dimensions of his occultism, more specifically his reflection on an encounter with the transcendental beings. The need for rearticulation of the role of the ethical, that is the relation to the other gains urgency because the transcendental beings are by nature obscure, indistinct, and indefinite. They resist too much clarification and determination that may reduce their complicated and irreducible beings to distinct concepts. The difficulty, therefore, lies in the question of how Yeats could present the beings in a manner as precise, proper, and rigorous as possible and at the same time he could respect and honor the mode in which the beings conceals themselves in the mystery, by letting them be the mystery that they are. A Vision was the culmination of Yeats’s lifelong wish to relate the divinity of the supernational beings to the human soul. In order not to present God as a personal deity, Yeats says only about the nearest equivalent his system offers to God, the gnomically-named Thirteenth Cone. The Cone is actually a sphere because sufficient to itself, but as seen by man it is a cone. It is more a symbol of the human relationship to the ultimate being than a symbol of that ultimate itself. Otherwise unknowable, the supernatural beings could be evoked by symbols. The symbol's job for Yeats therefore is not, first and foremost, cognition, in the sense of understanding, calculation, and definition, but instead bringing what is other for language and thought into the openness of its alterity and maintaining this alterity against the power of cognitive assimilation. Yeats lets the symbols work up the mind to evoke the world of the supernatural beings, which will remain unknown to those who relay on the evidence of their senses. “The Cold Heaven” gives a good illustration of the human relation to the supernational beings, for it combines Yeats's own personal history with his supernatural vision. Staring at a winter sky, he desperately looks back at where his life has gone, gathering together in a passionate fusion the lacerating memory of his failure with Gonne and his themes of death, ghosts and dreams. Supernatural Songs shows how Ribh's ecstasy in an encounter with the supernatural being not only arises from the contemplation of things vaster than the individual and imperfectly seen but also escapes from the barrenness and shallowness of a too conscious arrangement. "The Spirit Medium" well exemplifies the phenomenon of permeable structure inhabiting different regions of reality simultaneously so that the world of the supernatural being and that of the individual, inside and outside, one side and the other, subject and the other, appear as correlated and overlapped as equal parts of the inhuman symbolic spirit medium.

Soil texture, pH, organic carbon, organic matter, organic nitrogen, total phosphorus and chemical speciation were studied on the soil samples from Dok-do, Korea. Dok-do soil was composed mostly of silt, and textures were silt and silt loam. Soil pH was normally neutral but in some areas, acidic and very high content of organic matter. High content of organic matter explained the origin of Dok-do soil was related to the vegetation of the island. C/N ratio of the soil organic matter 15 meant the organic matter in the soil had moderately degraded plant debris. The most important chemical speciation of soil phosphorus in Dok-do was Residual P, meant the source of soil phosphorus was plant, and high ratio of Apatite P was considered to relate to the feces of water bird of the area.

색소변이체에서 버섯 바이러스의 게놈인 dsRNA가 확인 되었으며, 크기는 각각 5.8kb, 1.8kb 이었다. 느타리바이러스 진단용 프라이머인 PVP로 RT-PCR을 수행한 결과 500bp 크기의 특이밴드가 관찰되었다. 또한 양송이 바이러스 진단용 프라이머 LIVP와 MBVP에서도 특이밴드가 관찰되었으나 양송이 바이러스와는 다른 양상이었다. 원형느타리의 백색변이체 (MGL2205)에 존재하는 바이러스유사입자는 구형이었으며, 크기는 14, 20∼45nm이었다. 균사체의 세포단면을 관찰한 결과 바이러스 순화액에서 확인된 바이러스유사입자와 비슷한 구형의 입자들이 관찰되었으며, 순화된 바이러스와 동일한 입자인지는 추후 확인되어야 할 것으로 사료된다. 원형느타리 백색변이체(MGL2205)에 존재하는 바이러스의 최적 증식 조건은 15℃, pH 6, 배양기간 3주인 것으로 판단되며, 이 결과는 이와 유사한 재배적 조건에서 재확인되어야 할 것으로 사료된다.

The aim of this study is to establish an efficient distribution planning for a capacitated multi-stage supply chain. We assume that the demand information during planning horizon is given a deterministic form using a certain forecasting method. Under such a condition, we present a cost effective heuristic method for minimizing chain-wide supply chain inventory cost that is the sum of holding and backorder costs by using look-ahead technique. We cope with the capacity restriction constraints through look-ahead technique that considers not only the current demand information but also future demand information. To evaluate performance of the proposed heuristic method, we compared it with the extant research that utilizes echelon stock concept, under various supply chain settings.

This study was carried out to investigate the presence of L. pneumophila in indoor air and water collected from 692 air conditioning cooling towers at different public facilities. For these 4 years (2001～2004) of investigation, water samples were collected in high air conditioner operating month (from July to September) at department stores, hotels, offices, hospitals, discount stores, and public agencies. It was found that L. pneumophila was present in water samples from 47 air conditioning cooling towers. The detection rate of L. pneumophila was 7.6% in 2001, 10.7% in 2002, and 9.5% in 2003, respectively. When we compared the 4 air conditioner operating months, the highest rate of L. pneumophila detection was obtained in the water samples of July. The detection rate of L. pneumophila differed among different facilities. The highest detection rate of 17.9% was found in samples from department stores. L. pneumophila was detected similarly in water samples from hospitals (8.3%) and offices (8.2%). pH, temperature, and turbidity in the 47 L. pneumophila positive water samples ranged from pH 7 to 9, from 25℃ to 38℃, and from 1.0 to 3.5, respectively.

The purpose of this study was to analyze the features of the avant-garde architecture in the end of the 20th Century based on the ontology as a metalanguage. In view of the results so for achieved, it is possible to say that the thought of becoming, topology, rhizome thought and the Deleuze's concepts of the fold and the event as ever-changing and evolving at any given time are found in the avant-garde architecture, and the introduction of ontological thought into architectural design encourage hopes for a more natural and existential quality in architecture. However, the avant-garde architecture in the end of the 20th century disclosed the limitation in the architectural expression of ontological thought due to the lack of fully understand on ontology. In conclusion, the ontological approach in architecture offers a new morphological methodology and a new way of programming considering the existential aspect of space through the bricoleur's means leaving the ontological meaning of architecture itself.

We propose a new algorithm for a classical problem in the planer computational geometry: computing a shortest path between two points in the presence of circular obstacles. Proposed algorithm actually computes a path tree that encodes a shortest path between given two points. Types of path are defined as a tangent line segment between circles, between point and circle, or as an arc. Using circle set voronoi diagram, geometric information that is very useful to search circles is obtained. The key of proposed algorithm is the reduction of the number of circles to need for constructing path tree. The main advantages of our algorithm are its robustness, speed, and the simplicity in implementation.
