This paper describes the information for quantitative simulation of weakly ionized plasma. In previous paper, we calculated the electron transport coefficients in $CF_4+Ar$ gas mixture by using two-term approximation of Boltzmann equation. but there is difference between the result of the two-term and the multi-term approximation of the Boltzmann equation in $CF_4$ gas. Therefore, in this paper, we calculated the electron drift velocity (W) in $CF_4+Ar$ gas mixture for range of E/N values from $0.01\sim500[Td}$ at the temperature was 300[K] and pressure was 1[Torr] by multi-term approximation of the Boltzmann equation by Robson and Ness. The results of two-term and multi-term approximation of the Boltzmann equation has been compared with each other for a range of E/N.

In this paper, we will define direct producted $W^*-porobability$ spaces over their diagonal subalgebras and observe the amalgamated free-ness on them. Also, we will consider the amalgamated free stochastic calculus on such free probabilistic structure. Let ($A_{j},\;{\varphi}_{j}$) be a tracial $W^*-porobability$ spaces, for j = 1,..., N. Then we can define the corresponding direct producted $W^*-porobability$ space (A, E) over its N-th diagonal subalgebra $D_{N}\;{\equiv}\;\mathbb{C}^{{\bigoplus}N}$, where $A={\bigoplus}^{N}_{j=1}\;A_{j}\;and\;E={\bigoplus}^{N}_{j=1}\;{\varphi}_{j}$. In Chapter 1, we show that $D_{N}-valued$ cumulants are direct sum of scalar-valued cumulants. This says that, roughly speaking, the $D_{N}-freeness$ is characterized by the direct sum of scalar-valued freeness. As application, the $D_{N}-semicircularityrity$ and the $D_{N}-valued$ infinitely divisibility are characterized by the direct sum of semicircularity and the direct sum of infinitely divisibility, respectively. In Chapter 2, we will define the $D_{N}-valued$ stochastic integral of $D_{N}-valued$ simple adapted biprocesses with respect to a fixed $D_{N}-valued$ infinitely divisible element which is a $D_{N}-free$ stochastic process. We can see that the free stochastic Ito's formula is naturally extended to the $D_{N}-valued$ case.

심장점액종은 심장에 나타날 수 있는 가장 흔한 원발성 종양이다. 주된 증상으로 고열, 체중감소, 피로, 권태감, 관절통 등을 호소할 수 있어 감염성 심내막염의 증상과 비슷하지만 감염되는 경우는 극히 드물다. 본원에서는 76세 남자환자가 고열 및 일시적인 의식소실을 주소로 응급실로 내원하였으며 좌심방 점액종의 진단하에 저혈압성 쇼크에 빠져 응급으로 수술을 시행한 감염된 좌심방 점액종을 보고 하고자 한다.

최근들어 UMTS(Universal Mobile Telecommunication System)는 3세대 무선망의 표준으로 인식되고 있고 DSCH(Down-link Shared Chanel)는 UMTS에서 매우 효율적인 다중화 방안으로 고려되고 있다. 그러므로 UMTS에서의 DSCH를 위한 효과적인 패킷스케줄링 알고리즘 개발에 대한 연구가 필수적이다. 본 논문은 UMTS의 DSCH를 위한 개선된 패킷스케줄링 알고리즘에 대하여 기술한다. 이 알고리즘은 최대 링크 이용율을 위하여 이동호스트채널상태를 고려하며, 동시에 장기적으로 공정성을 얻기 위해 3등급 트래픽에서의 지연 한계치와 4등급 트래픽의 처리율을 함께 이용한다. 알고리즘의 타당성을 보이기 위하여 PARSEC을 이용한 모의실험을 수행하였다. 모의실험 결과는 이 알고리즘이 무선링크 이용율과 공정성 두 가지 측면에서 적적한 타협(trade-off)을 통하여 개선된 결과를 얻을 수 있음을 보여준다.

신자유주의 경제의 확산으로 인해 전세계 인구 이동의 흐름은 급격히 변화해왔으며, 단일민족 국가라 믿어왔던 한국 역시 이러한 흐름으로부터 자유로울 수 없었다. 전형적인 노동력 수출국이었던 한국은 이제 노동력을 수입하는 주요 국가이며, 이주민들로 인해 사회적 지형은 지난 십 수년간 급격히 변화해왔다. 그러나 이에 대한 미디어의 재현은 지극히 제한적이고 정형화되어 있다. 따라서 본 연구의 주목적은 한국사회의 시대적 변화 속에서 지상파 방송사들이 뉴스 콘텐츠를 통해 이주민들을 재현하는 양식을 영상담론을 통해 분석하는 것이다. 연구결과 지상파 방송뉴스에 재현된 이주민들은 특정한 영상재현 방식으로 담론화되며, 이는 한국인들과의 이항대립을 이루어 그들에 대한 스테레오타입을 확대재생산하는 메커니즘으로 작용한다는 것을 밝혀냈다.

Let F be a life distribution with finite mean $\mu$ Then F is said to be in new better then worse than used in expectation (NBWUE(p)) class if $\varphi(u) {\geq} u$ for $0 {\leq}u{\leq}t_0$ and ${\varphi}(u) {\leq} u$ for $t_0< u {\leq} 1$ where ${\varphi}(u)$ is the scaled total-time-on-test transform and $p=F(t_0)$. We propose a testing procedure for $H_0$ : F is exponential against $H_1$ : NBWUE(p), and is not expontial, (or $H_1\;'$ : F is NWBUE (p), and is not exponential) using randomly censored data. Our procedure assumes kmowledge of the proportion p of the population that fail at or before the change-point $\t_0$. Know ledge of $\t_0$ itself is not assumed. The asymptotic normality of the test statistic is established and a Monte Carlo experiment is performed to investigate the speed of convergence of the test statistic to normality. The power of our test is also studied.

본 논문에서는 개인별 평균차를 이용한 최대 엔트로피 기반 감성 인식 모델을 제안한다. 정확하게 사용자의 감성을 인식할 수 있도록, 제안하는 모델은 단순하게 주어진 입력 감성 신호 정보만 분석하여 사용하지 않고, 입력 정보를 각 감성 상태의 평균값과 비교한 결과를 활용한다. 그리고, 자료 부족 문제를 완화하기 위해서, 제안하는 모델은 평균차를 +(양수)와 -(음수)로 단순하게 표현하고, 감성 반응 전체 시간 대신 초단위로 분할하여 감성신호의 평균을 계산한다. 또한, 전문적인 지식이 없이도 구축이 용이하도록, 제안하는 모델은 간단한 평균차 계산 기법과 잘 알려진 기계학습기법의 하나인 최대 엔트로피 모델을 이용한다.

William Shakespeare's dirge, "The Phoenix and the Turtle," is still a crux in the Shakespearean canon and interpretation. The poem is still believed a dark allegory dealing with some arcane and obscure courtly matters and politics. However, we cannot recover its allegorical significance. This interpretive situation enforces us to read the poem as a self-conscious artwork in terms of its paradoxical language and meta-poetic metaphors. Paradox, as a subspecies of metaphor, challenges categorical and judgmental absolutes, and produces a sense of wonder in reconciling the logically contradictory opposites. In this poem the urn containing the ashes of the phoenix and the turtle is the icon of the mysterious unity of art, born of the wonderful marriage of male and female. Shakespeare's poem demonstrates in itself the magical power of poetic language in transforming an elegy into an epithalamion. The union of the phoenix and the turtle defies the singularity of their respective entity, and at the same time it retains their distinctive particularity of the two-ness. This neo-Platonic mystery of the "married chastity" is a paradox which confounds reason and verifies the poetic truth of imaginative intellect. The marriage of Christian perichoresis is crystallized in the artwork of the urn, which is admired at by posterity, though the marriage was issueless, due to its passing virtue. "The Phoenix and the Turtle" depicts the metaphor-making process and its effect, the poem.

People enthusiastic about human brands eagerly engage in fan communities to share their common interests with others. Although sharing one's enthusiasm towards the same celebrities can give thempositive senses of we-ness (in-group identity, togetherness, camaraderie) and belongingness, negative sides also exist such as schadenfreude and trash talk. Even though the studies addressing the negative sides of fan community are gaining significance, no prior studies formally examined the negative consequences of engaging in a fan community and their effect on one's well-being. Therefore, this current study aims to investigate how engaging in fan community negatively affects members' psychological well-being through schadenfreude and trash talk. Structural equation modeling analysis revealed that engaging highly in a fan community leads members to feel malicious pleasure at rivals' misfortunes and share negative opinions of rival human brands and fan communities. These negative consequences of fan community engagement ultimately lead to a lower level of psychological wellbeing, especially in the area of personal growth whereas fan community engagement has a direct positive effect on personal growth. By showing the negative influences of engaging in fan communities on members' well-being through schadenfreude and trash talk, the results of this study are expected to add depth to the existing literature.

Purpose : This study was investigated, in order to improve that reliability of disease mechanism diagnosis, which were used for the object diagnosis of Oriental medicine in the dept. of Oriental OB&GY, Oriental Medical hospital of Dong-Eui University, amend to a disease mechanism item of Questionnaires and indexes of disease mechanism, we were thought that the results were more pointed to the condition of appropriate disease mechanism, as a result of put a results of Questionnaires and belongs to indexes of disease mechanism together, we　suggested to call it a　'weight of disease mechanism', because It was possible to　mark a different degrees of indexes of disease mechanism in the same points.　Methods : We analyzed the results of Questionnaires about 3354 outpatients who　had OB&GY disease in the Oriental Medical hospital of Dong-Eui University from April 2000 to March 2004. Results : 1. weight of disease mechanism is 10 score according to disease mechanism score and the standard of reliability. 2. The standard of reliability is same 11 disease mechanism item except stagnated blood, cold syndrome, dry- ness, phlegm. Conclusion : Weight of disease mechanism which show satisfaction the conditions of standard of reliability, appear the results of Questionnaires, against previous study investigated reliability of Questionnaires make it through the standard of reliability.
