Extensive screening for cellulose-producing bacteria was done using differential media. Fifty seven strains were isolated totally from the fruits and the vinegar, respectively; the isolate A9 strain from apples was selected and examined to determine its taxonomical characteristics. The bacterium was identified as the genus Acetobacter sp_ based on morphological, cultural and biochemical properties. A9 strain produced acetic acid from ethanol and decomposed acetic acid to $CO_2$ and $H_2O$. They produced dihydroxyacetone from glycerol but did not produce y-pyrone from glucose and fructose. When A9 strain was cultivated statically in Hestrin and Schramm liquid medium(HS medium). thick cellulose pellicle was formed_ Higher cellulose production was obtained in the shaken culture using HS medium at 100 rpm.

The purposes of the study were to analyse the colors and, color combinations effect on the image perception using gestalt theory. The research method was a quasi-experimental with a between subjects design. The experimental materials developed for the study were a set of stimuli and a response scale. The stimuli was consisted of 17 drawings of females wearing Korean traditional dress, by using CAD simulation. A response scale consisted of semantic differential scales. The subjects were 1138 undergraduate students of Taejon city, Chungnam province and Chungbuk province. Their responses to the semantic differential scales were analyzed using factor analysis, ANOVA, Duncans multiple range test. Results were as follows; 1) The colors effect of blouse was significantly greater than the effect of skirt, and no interaction effect was found between blouse colors and skirt colors. 2) In bi-color combination dress set, the combined image of the two colors were compared to the image of the two mono color sets: No single principle was found, however, salient color (such as yellow) and unattractive color (such as green) seemed to act as central trait colors on the image perception. On conclusion the visual image of Korean traditional dress wearer was affected by central trait colors in bi-color combination, and this results support the gestalt theory with central traits.

In this paper, a new form of linear models referred to as generalized weighted linear models is proposed. The proposed models assume that the relationship between the response variable and explanatory variables can be modelled by a distribution function of the response mean and a weighted linear combination of distribution functions of covariates. This form addresses a structural problem of the link function in the generalized linear models in which the parameter space may not be consistent with the space derived from linear predictors. The maximum likelihood estimation with Lagrange's undetermined multipliers is used to estimate the parameters and resampling method is applied to compute confidence intervals and to test hypotheses.

Dresses of the 1950s and 60s when the range and changes of fashion were wide and heavy were closely related with various styles of that time's architecture from the form, use of material, structure to the color. In this, study, characteristics of formalism and brutalism, main architectural streams of that period, such as line, structure, function, material, texture and color are analyzed in detail and these characteristics and those of dress are compared and analyzed to see if there are common aesthetic senses between them. It is particularly noteworthy that at that time formalistic architecture represented joy and abundance through enriched creation of appearance and flowing, symbolic linear beauty while the brutalistic produced young and vivid liveliness through functional, reasonable and moderate beauty, and this young and joyful atmosphere coincided exactly with frank, lively aesthetic senses of the young generation's fashion. Therefore, we can see common significance in the following fact ; architectural modes and fashion art of the 1950s and 60s were the result of more humane and enriched expressions from economical growth, and also product of that time's desire to adapt itself realistically to the rapid, complicated pop culture resulted from mass production.

이 글은 1993년 4월 5일에서 8일 사이 영국의 에쌕스 대학교 (Univ. of Essex) 에서 열렸던 연례 영국 사회학회에서 발표되었던 글을 줄이고 다시 다듬은 것이다. 따라서 최초의 내용과는 꽤 차이가 있다. 지난 반세기 동안 이 땅에 밀어 닥쳤던 산업화, 도시화를 비롯한 이른바 근대화에 의하여 엄청난 사회변동을 겪었다. 인구학적으로든, 문화적으로든, 그리고 경제 성장면에서나 사회적으로도 변화의 폭과 속도는 다른 어느 나라와도 비길 수 없는 거대한 것이었다. 이런 변화의 물결 속에서 한국 가족은 스스로 많은 변신을 하여야 했다. 그리고 그 변화는 그 자체가 또 하나의 사회적 힘으로 등장하여 제2, 제3의 영향력을 현대 한국인의 일상생활에 연속적으로 끼쳤다. 그럼에도 불구하고 전통적 가치관은 사회구조의 중요한 부분들을 차지하고 여전히 한국인의 삶을 조정하고 있다. 이 논문은 위와 같은 맥락에서 가족구조의 변동을 분석하고 있다. 우선, 한국의 가족크기는 어떻게 바뀌었는가 현대 한국인들 사이에 가장 자주 관찰되는 가족유형은 어떤 것이 있는가 또한 일반적 유형으로부터 벗어나 버린 가족형태에는 어떤 것들이 있으며 그런 것들은 어느만큼 뚜렷한 존재로 증가하였는가 등을 따져 보았다. 지난 4반세기 동안 일어 났던 가족분야의 변동은, 전통적 가족주의의 원리가 전반적으로 약화하였다는 점에서 기존의 근대화 이론의 논의와 일치하고 있다. 하지만 전통적 원리가 비록 미약하나마 여전히 존재하며, 생각지도 못하였던 가족 형태가 증가하기 시작하였다는 점에서 근대화 이론의 타당성은 재음미되어야 하리라 본다.

This paper presents the Genetic Algorithm based Task Scheduling (GATS) method for the scheduling of programs with diverse embedded parallelism types in Distributed Parallel Systems, which consist of a set of loosely coupled parallel and vector machines connected via high speed networks The distributed parallel processing tries to solve computationally intensive problems that have several types of parallelism, on a suite of high performance and parallel machines in a manner that best utilizes the capabilities of each machine. When scheduling in distributed parallel systems, the matching of the parallelism characteristics between tasks and parallel machines rather than load balancing should be carefully handled with the minimization of communication cost in order to obtain more speedup. This paper proposes the based initialization methods for an initial population and the knowledge-based mutation methods to accommodate the parallelism type matching in genetic algorithms.

This paper proposed an analytical framework to compare and model the policy-based network management; centralized and distributed typed model. Policy-based network is introduced in various application fields, and a policy framework can offer different processing performance according to application. Therefore, we evaluated the performance and extensibility of each PBNM model when we apply the policy process to the models. The evaluated measurement metrics are policy provisioning time, traffic occurrence amount, PDP processing rate, and global conflict detection in qualitative simulation. The results show that the suitable structure is required according to the analysis for the careful application characteristics, when PBNM is adopted. The modeling framework presented in this paper is intended to quantify the merits and demerits among the currently suggested PBNM models.

This paper investigated the conceptual schemes four children constructed as they related division number sentences to various types of fraction: Proper fractions, improper fractions, and mixed numbers in both contextual and abstract symbolic forms. Methods followed those of the constructivist teaching experiment. Four fifth-grade students from an inner city school in the southwest United States were interviewed eight times: Pre-test clinical interview, six teaching / semi-structured interviews, and a final post-test clinical interview. Results showed that for equal sharing situations, children conceptualized division in two ways: For mixed numbers, division generated a whole number portion of quotient and a fractional portion of quotient. This provided the conceptual basis to see improper fractions as quotients. For proper fractions, they tended to see the quotient as an instance of the multiplicative structure: $a{\times}b=c$ ; $a{\div}c=\frac{1}{b}$ ; $b{\div}c=\frac{1}{a}$. Results suggest that first, facility in recall of multiplication and division fact families and understanding the multiplicative structure must be emphasized before learning fraction division. Second, to facilitate understanding of the multiplicative structure children must be fluent in representing division in the form of number sentences for equal sharing word problems. If not, their reliance on long division hampers their use of syntax and their understanding of divisor and dividend and their relation to the concepts of numerator and denominator.
