신장유동의 예로 등온 방사공정을 구성방식의 예로 변형률속도에 따라 변하는 풀림 시간을 가지는 White-Metz-ner 모델을 사용해서 점탄성유체의 거동에 관한 해석적 연구를 수행했다, 그결과 풀림시간의 변형률속도에 대한 의존도에 따라 점탄성유체를 두가지로 구 분할 수 있음을 알 수 있었다, 다시말해서 풀림시간이 변형률속도에 대해서 작은 의존도를 가지는 그룹I의 유체의 경우는 변형률속도가 커짐에 따라 신장점도가 증가하며 Weissen-berg수 (무차원 풀림시간)가 커짐에 따라 방사사선의 속도가 증가한다, 반면에 풀 림시간이 변형률속도에 대해서 큰 의존도를 가지는 그룹 II의 유체의 경우는 변형률 속도가 커짐에 따라 신장점도가 감소하며 Weissenberg수가 커짐에 따라 방사사선의속도가 감소한 다. 이렇게 대조적딘 점탄성유체에 관한 결과는 유사한 거동을 보고한 다른 연구자들의 결 과와 잘 부합한다. 또한 Weissenberg수가 다른경우의 신장점도 곡선들을 무차원 변형률속 도를 Weis-senberg수에 비례하게 Shift 시키면 master Curve를 얻을수 있었다.

Geomancy accepts with a pre-requisite that human beings adapt themselves to nature as an organism, because people and environment, bodies and space have the homogeneity which can not be divided by a dichotomy. The homogeneity as a structure alive implies a deep relationship with biorhythm and the change of space, and is regarded as a concept and role significant on the coordination. In other words, applying the element in the geomancy could be interpreted as a work giving a new meaning and spirit on a creation of space and furniture coordination. Harmony and balance shown in design concepts have a relationship with the meaning on Yin-Yang and the Five Elements theory. In addition, the characteristic in each element is suggested as an example applying the concept of geomancy through furniture coordination for each space in the chapter 4.

In our recent investigation of the Oosterhoff dichotomy among globular clusters (GCs), we have shown that the RR Lyrae variables in the Oosterhoff groups I, II, and III are produced mostly by first, second, and third generation stars (G1, G2, and G3), respectively. Unlike GCs, RR Lyrae stars in the Local Group dwarf galaxies show Oosterhoff-intermediate characteristics. The origin of this, however, is yet to be understood. In this poster, we will present our progress in understanding the origin of this phenomenon.

The Public Vehicle Routing Problem (PVRP) is to find the minimum total cost routes of M or less Public-Vehicles to traverse the required arcs(streets) at least once, and return to their starting depot on a directed network. In this paper, first, a mathematical model is formulated as minimal cost flow model with illegal subtour elimination constraints, and with the fixed cost and routing cost as an objective function. Second, an efficient branch and bound algorithm is developed to obtain an exact solution. A subproblem in this method is a minimal cost flow problem relaxing illegal subtour elimination constraints. The branching strategy is a variable dichotomy method according to the entering nonrequired arcs which are candidates to eneter into an illegal subtour. To accelerate the fathoming process, a tighter lower bound of a candidate subproblem is calculated by using a minimum reduced coast of the entering nonrequired arcs. Computational results based on randomly generated networks report that the developed algorithm is efficient.

The purpose of this research is to understand the gender identity expressed in Madonna music video texts and performances. Madonna has reconstructed the fluid identities through the variations of body, images, costumes, and attitudes . The results are as fellows; ① Her punky sexuality is to be seen the flash trash look, kitsch fashion, which reconstructs a good/bad taste, modesty/immodesty, the relations of under/outer wear using bawdy sexuality through her early Virgin tour. ② Her Heterosexuality is to be seen the glamourous look, traditional images of women, which represents the passive feminity of patriarch. ③ Her sadomasochism sexuality is to be seen the bondage look of dominatrix image, which deconstructs sexual taboos; represents sexual power. ④ Her bisexuality is to be seen androgynous look, the 3rd species look using masculinity/feminity signifier, which deconstructs the stereotypes of gender roles. ⑤ Her homosexuality is to be seen the fetish fashion by drag and lesbian, which deconstructs the dichotomy of normality/perversion; opens a possibility of women subjectivity of sexual desires.

This presentation aims to explore some possibility of non-segmental phonetics usually ignored in phonetics education. In pedagogical phonetics, especially ESL/EFL oriented phonetics speech sounds tend to be classified in two criteria 1) 'pronunciation' which deals with segments and 2) 'prosody' or 'suprasegmentals', a criterion that deals with non-segmental elements such as stress and intonation. However, speech involves more dynamic processing. It is non-linear and multi-dimensional in spite of the linear sequence of symbols in phonetic/phonological transcriptions. No word is without pitch or voice quality apart from segmental characteristics whether it is spoken in isolation or cut out from continuous speech. This simply tells the dichotomy of pronunciation and prosody is merely a useful convention. There exists some room to consider dynamic non-segmental phonetics. Examples of non-segmental phonetic investigation, some of the analyses conducted within the frame of Firthian Prosodic Analysis, especially of the relation between vowel variants and foot types, are examined and we see what kind of auditory phonetic training is required to understand impressionistic transcriptions which lie behind the non-segmental phonetics.

The aim of this paper is to describe the prosodic structure of Korean related to the syllable duration varying with its positional difference. An attempt is made in this study to analyze and describe the concrete correlation between the syllable lengthening and its position in the utterance at the initial and final positions. Using the syllable [na] at the final and initial position of a prosodic phrase in the Korean version of 'the North Wind and the Sun', it has found that the ratio of phrase final versus phrase initial syllable lengthening was approximately 1.8:1 for 4 subjects taking part in the test. In the case of nonsense data, we found that the ratio was approximately 1.6:1 for 2 out of 3 subjects. The results of this study might indicate that Korean tends to have a high rate of final lengthening. We can tentatively classify it, therefore, as a stress-timed language. Still, there is no denying that further studies should be done before we can be absolutely certain about the classification of languages along the dichotomy scale.

The primary purpose of this study was to analyze the types of home managers in association with effects of resourcefulness, communication and the conditions for effective home management＇ proposed by Shape and Winter(1991). A survey was conducted by subjects of 300 wives in Kwangju city. The statistical data were obtained by cluster analysis, one-way ANOVA, Duncan＇s test and chi-square test. Manager types based on the four conditions, resourcefulness and communication were classified into four clusters. Educational background, job status, family types, family life cycle and age difference between the oldest and the youngest child of the subjects were different from manager types. In conclusion, this study identified the four conditions of performance-condition dichotomy, timing, high level and middle range, resourcefulness, and communications in order to develop managerial capability.

This paper discusses the nature of the associate NP of English there constructions and attempts to capture the underlying similarity between the associate NP in English and the nominative object in Korean. Specifically, this paper is centered on the Case property of the associate NP. As the first step, previous proposals on the case of the associate NP are critically reviewed. Through the criticism, this paper opposes to Chomsky's (1995, 2000, 2001) analysis and to Lasnik's (1999) partitive Case analysis. In particular, convincing reason for the partitive Case assignment to the associate NP, other than other cases, cannot be found. This paper, therefore, adopts a recent claim of Boeckx (2000) that the Case under consideration is nominative by Agree. His idea is extended to the analysis of the presentational expletive construction. This paper draws a conclusion that the associate NP of the presentational expletive construction has accusative by Agree. This dichotomy (or split) is also observed in the nominative object construction in Korean. In the nominative object construction, the nominative object has nominative Case by Agree, whereas the regular object has accusative by Agree.

This paper takes issue with the idea of language as a 'serial-time structure' as opposed to the 'real-time event' of speech, an idea entrenched in Chomskyan model of linguistic theory. The discussion centers around the leitmotif question: Is language constructed entirely from a finite set of apriori discrete symbol types, as the 'competence vs performance' dichotomy implies\ulcorner A set of linguistic patterns examined in this study, largely with regard to phonological considerations, points to the evidence to the contrary. That is, while the patterns may be said to be linguistically distinct, they are not discretely, different, i.e. not different enough to be reliably differentiated. It is demonstrated that much of current research in phonology, including the most recent Optimality Theory, is misdirected in that it falsely presupposes a discrete universal phonetic inventory. The main thrust of the present study is that there is no sharp boundary between 'competence' defined as the formal, symbolic, discrete time domain of language and human cognition on the one hand and 'performance' as the continuous, fuzzy, real-time domain of human physiology on the other.
