Using a Monte-Carlo simulation technique we evaluate the empiricla distribution of a pseudo-chi-square statistic based on symmetrically Winsorized sum of squares when the population is normally distributed, and search for a chi-square distribution with appropriate degrees of freedom which can be referred to an approximate distribution for Winsorized chi-square.

사람은 한 장소를 방문할 때 순환 패턴이 있으며, 이 패턴에 여러 싸이클의 경향이 있다. 요즘은 스마트폰 및 기타 휴대용 장치로 개인 이동성 데이터를 수집하는 것이 가능하다. 이러한 장치는 다양한 위치 데이터를 수집하고 여러가지 방법으로 분석할 수 있게 해준다. 위치 수집기를 기반으로 지구 위치 데이터에서 추출된 사람의 이동성 모델을 수립하고, 위치 클러스터를 방문자의 순환 패턴을 조사할 수 있다. 수년 동안 수집된 개인의 이동성 모델을 토대로 클러스터 재방문 시간을 계산 후 분석하여 그래프로 시각화하였다. 시간 순서의 위치 클러스터와 방문 클러스터에 대한 위치 데이터는 1 분 단위로 측정된다. 전체 데이터 방문 횟수는 15 분마다 정규화하고, 자원 봉사자의 다양한 지리적 위치 데이터 셋에 대해 방문의 순환 패턴은 자기 상관, 자기 공분산 및 재방문 시간으로 살펴볼 수 있다.

Multiculturalism may be deeply connected with the diversities of cultures and enlightenment discussed in the context that we live together with the specification of cultures derived from any spatial conditions overtly and covertly. People live on their own customs compatible with their space and the time, and they make their boundaries of races, nations, and national memories. In such a way each of them treats each other exclusively and is inclined not to recognize being of the others. Also people are apt to recognize the others unessentially and overlook the others's value and way of life. As a result they might destroy the foundation of symbiotic livings conditions on their own. On the other hand they pretend to search for the cultural diversities of the others and include them under their own universalities, resulting in conflicts. Hence it is required that we should make an efforts to prepare the fields for living together through getting over the problem of the recognition of matters and affairs before us. From the above-told critical mind this thesis seeks the multicultural relativities and more arrives at the relationalities discussed by East-Asiatic philosophers of Chuang Tzu and Ch'oe Han-gi. Especially by gazing at the idea of the interconnectedness which means activities, changeabilities and mobilities, appeared on the idea of Ch'oe Han-Gi's revolving transformation, it is stressed that the communications of the local with each other in the various aspects of, e.g. materials, regions and cultures should be achieved.

In this paper, I would like to reconsider the evidential category (or the mediation category) in languages with language specific values, especially in Korean and French evidentials. We tried to analyze how the evidentials are represented in both languages including their linguistic markers (grammatical, lexical or discursive) and their semantic meanings. According to the precedent studies from the general linguistic point of view, we would like to reconsider the semantic meanings of both languages' grammatical markers, the so-called Korean retrospective marker '-te-' and French conditionals in the framework of the enunciative operation theory suggested by $Descl{\acute{e}}s$ & $Guentch{\acute{e}}va$ (2000), which proposed to classify the type of discourse by the language-independent description tools conceived after the enunciation theory suggested by Bally (1965), Benveniste (1956), Culioli (1973). Through this approach, we would like to contribute to establishing the linguistic basis not only for the general linguistic research to determine the invariant meaning of linguistic evidentials and their system, but also for the applied linguistics to the language engineering field.

Fish assemblages associated with eelgrass beds and unvegetated area were compared based on specimens collected every month in Jindong Bay. The common fish species were Hexagrammos otakii, Acanthopagrus schlegeli, Lateolabrax japonicus, Pholis nebulosa, P. fangi, Leiognathus nuchalis, Repomucenus valenciennei, and Acanthogobius flavimanus. H. otakii, A. schlegeli, P. nebulosa and L. japonicus were higher abundance in an eelgrass bed than unvegetated area, whereas P. fangi, R. valenciennei and A. flavimanus were higher in unvegetated area. Sillago japonicus, Hippocampus japonica, Takifugu niphobles, Pseudoblennius percoides, Sebastes inermis, Syngnathus schlegeli, Sebastes schlegeli were found in an eelgrass bed, but not in unvegetated area. Most of fish species were primarily small fish species or juveniles of fish species in an eelgrass bed, while larger fish species were found in unvegetated area. The eelgrass bed in Jindong Bay seem to play a nursery role for fishes. Seasonal variations in both species composition and abundance were large in two habitats; higher number of species and individuals occurred May 2002, and April 2002 to July 2002, while biomass was the highest in April 2002 and July 2002. Fish numbers as well as biomass were lowest in January 2002. Species richness, number of individuals and biomass of fishes in an eelgrass bed were significantly higher than those of in unvegetated area. These result suggest that differences in fish species richness and abundances are primarily related to habitat structure. Different habitat preferences were evidenced for the juveniles and adult of several fish species.

The Au-Ag lode deposits in South Korea are closely associated with the Mesozoic granitoids. Namely, the Jurassic deposits formed in mesozonal environments related to deep-seated granitoids, whereas the Cretaceous ones were developed in porphyry-related environments related to subvolcanic granitoids. The time-space relationships of the Au-Ag lode deposits in South Korea are closely related to the changing plate motions during the Mesozoic. Most of the Jurassic auriferous deposits (about $165{\sim}145$ Ma) show fluid characteristics typical of an orogenic-type gold deposits, and were probably generated in a compressional to transpressional regime caused by an orthogonal to oblique convergence of the Izanagi Plate into the East Asian continental margin. On the other hand, strike-slip faults and caldera-related fractures together with subvolcanic activity are associated with major strike-slip faults reactivated by a northward (oblique) to northwestward (orthogonal) convergence, and probably have played an important role in the formation of the Cretaceous Au-Ag lode deposits (about $110{\sim}45$ Ma) under a continental arc setting. The temporal and spatial distinctions between the two typical Mesozoic deposit styles in South Korea probably reflect a different thermal episodes (i.e., late orogenic and post-orogenic) and ore-forming fluids related to different depths of emplacement of magma due to regional changes in tectonic environment.

The purpose of the present article is to understand moral instruction through Ethics written by Spinoza and enable the implications drawn from its understanding to give shape to lesson plans. In his representative book titled Ethics, Spinoza speculates ultimate substance from the metaphysical perspective and converges it into ethics. The ultimate substance, which is a cause of itself, refers to immanent cause of all things that have numerous attributes as essence. All things in nature develop the substance and exchange influence among individuals at the same time. A human in the influential relationship perceives things based on one's beneficialness and assigns moral words of good and evil. However, a human, who is a mode of substance, should escape from morals that are superficial, relative, and objective, in order to realize nature. Becoming a more complete human requires going through moral imagination in reality but going beyond the imagination ultimately. Moral instruction premises the moral imagination of a student who exists as a mode; meanwhile, it is a study to escape from the influence of moral imagination. Good and evil arise from the limitation that an existing human has, but if a life is to preserve the necessity of ultimate substance, moral instruction can be defined as the processes of alleviating the influence that hinders a human's nature from being realized. Giving shape to this processes with the basis on the Spinoza's epistemic argument, moral instructional texts can be composed of stages to form more adequate moral ideas about moral subjects gradually and cumulatively. The moral instruction like this expects moral awareness which is relatively perfect than the present moral imagination. Furthermore, with the teaching and learning like this sustained, it is expected that ultimately the limitation arising from sensible perception can be overcome to approach the realization of a human's nature.

인터넷 비지니스가 중요한 경쟁요소로 발돋음하고 있는 현재의 시점에서 인터넷 비즈니스 모델에 특허권을 부여한다는 것은 비슷한 성격을 가진 타 경쟁업체의 경쟁력을 약화시키고 이를 포기하도록 의도하는 독점적 전략의 일종이다. 미국에서는 Statestreet 사건을 비롯한 일련의 BM 특허에 관한 소송이 제기되어 이미 BM 특허를 인정하고 있는 상황이며 이를 기점으로 BM 특허권을 인정하는 것이 대세로 되고 있다. 기존의 특허와 다른 양상을 갖고 있는 BM 특허는 새로운 아이디어를 중심으로 그 사업성을 인정받는 영업 모델 특허인데 이는 현재 독점과 관련한 부정적인 인식으로 그 특허의 타당성과 특허보호기간 적용문제가 논란이 되고 있다. 외국의 특허로부터 국내 인터넷 사업을 보호하기 위하여 정부차원에서의 특허 인정 노력이 필요하지만 인터넷 사업의 경쟁력 있는 활성화를 위해서는 특허보호기간이 현행 20년보다 축소해야 한다는 반발도 만만치 않다. 인터넷 비지니스 후발주자인 한국은 서두르지 않으면 치열한 인터넷 경쟁에서 뒤쳐질 위험을 안고 있다. 선발주자들의 경쟁우위 전략을 따라잡기 위해서는 인터넷 비즈니스 전반에 대한 경쟁력 확보와 함께 BM 특허에 관한 준비와 활성화 계획을 철저히 마련하는 것이 중요하다. 그리하여 우리 나라의 인터넷 비즈니스 모델이 cyber market에서 공격성과 방어성을 모두 갖춘 우수한 모델로 키워나가야 한다.

소시지 제조시 저장기간 연장을 목적으로 첨가되는 potassium sorbate(0.5%, 1.0%)와 nit-rite 감소를 위하여 첨가되는 ascorbic acid의 농도(0.5%, 10%)를 조정하여 오미자 추출물 첨가 소시지의 저장성과 잔존 이질산염 함량을 1$0^{\circ}C$와 3$0^{\circ}C$에서 저장하면서 관찰한 결과 온도에 관계없이 pH, 수분, 부수력, 염도, TBARS, 색차 관능검사 모두 저장기간이 경과함에 따라 낮은 값을 나태었다.(P<0.05),그러나 오미자 첨가 소시지의 잔존 nitrite 함량의변화는 대조구에 비해 낮은 값을 나타내어, 아질산염이 감소된 기능성 소시지의 개발 가능성을 시사하고 있다.그러나 pH의 감소로 인하 보수력의 저하로 조직감이 떨어져 소시지 제조시 첨가 농도를 0.5% 이하로 낮추는 것이 바람직하다고 사료된다.

We investigate sorry: asymptotic stabilities of the zero solution for the perturbed linear differential system dx/dt=A(t)x+e(t, x)+f(t,x), by using Perron's method and integral inequalities, etc. and we also find some sufficient conditions that ensure some asymptotic stabilities of the zero solution of the system And hence we obtain several results of it.
