Chemical changes in components of ginseng roots by heat treatment were observed. We have let the roots of fresh ginseng, of steamed ginseng and the water soluble parts obtained from preparing steamed one be subject to our research. Acids, bases, neutral substances and genins from each one of the above came up to 12 fractions. Having the fractions through column chromatography and TLC test thereafter, we determined the Rf values of each spots presented. Among so many similar values of them, 15 spots of heterogenous component in the fresh ginseng and 6 spots in the steamed one, and 10 spots in that of water soluble parts wre detected. Considering this data obtained, we can assume that partialor all of some components of fresh ginseng might be passed into water parts while preparing steamed ginseng from fresh ones and also some components of the later (fresh ginseng) might have been converted into other substances while being heated.

The volatile components of Eutrema wasabi were prepared by distillation and ether extraction. The extracts were similar in the color, the odor, and the antimicrobial activity to allylisothiocyanate, the main ingredient of wasabi essential oil. The antimicdrobial activity of the extracts was evaluated and it was found that these had the antibacterial effect against a broad spectrum of pathogenic bacterial such as Staphylococcus, Escherichia, Pseudomonas and Salmonella.

Many similar class components are stored in object-storage but the object-storage has needed the retrieval function of correct component for reuse. Accordingly this paper designed the class component retrieval viewer of the object-storage by using the improved spreading activation strategy. Object-storage has made up of information of inheritance relation, superclass, subclass, and we defined the queries about each class function. Also we specified connectionist relaxation of the each class and query, finally we gained retrieval result which showed highest activation value order of class component information including the query function.

In this paper, we consider the second order probability matching criterion for the ratio of the variance components under the one-way random effect model. It turns out that among all of the reference priors given in Ye(1994), the only one reference prior satisfies the second order matching criterion. Similar results are also obtained for the intraclass correlation as well.

An improved heuristic procedure is presented which minimizes the changeovers of components in manufacturing printed circuit packs (PCP). The proposed procedure first groups similar components and PCPs together as in an existing method. The procedure then assigns each group to a machine such that the load on two machines is balanced. Considerable improvement is obtained compared to the best procedure available in the literature.

The various plant organs of fennel (Foeniculum vulgare Mill.) were investigated to identify their volatile components using Dynamic Headspace (purge & trap). They showed slight differences concerning the volatile components both qualitatively and quantitatively. Results revealed that trans-anethole (12.65%) was the major compound in the leaf. The highest compound was ${\alpha}-pinene$ (28.78%), and trans-anethole (7.90%) was highly detected in the stem. The maximum values were 5.64, 4.59, 1.58, 1.51, and 1.04% for ${\alpha}-pinene,\;{\gamma}-terpinene,\;{\beta}-pinene$, 1,8-cineol and fenchone, respectively in the flower. However, very little trans-anethole was detected (0.27%) in the flower. From these results, it was suggested that the major components were different depending on the plant organs. However it was demonstrated that the related plant organs like flower-fruit and leaf-stem contained the similar components.

본 논문은 한옥 설계 지원 시스템을 개발함에 있어서 부재의 수를 획기적으로 줄이면서 한옥을 설계할 수 있는 효과적인 부재 표현방식을 제안하고자 한다. 한옥은 규모, 지붕의 모양, 공포의 유무 등에 따라 다양하게 분류할 수 있으며 결구방식 및 연결부재에 따라 부재의 수가 매우 다양하다. 이러한 다양한 부재를 모두 설계하게 되면 설계 시에 부재의 사용과 취급이 어려워진다. 이러한 문제를 해결하기 위해서 전남 표준한옥올 중심으로 한옥의 목구조 방식을 체계적으로 분석하고 특성이 비슷한 부재들을 모아서 하나의 템플릿으로 설계하여 다양한 형태의 유사부재들을 속성 값에 따라 자유롭게 생성할 수 있도록 객체지향 방식의 표현기법을 사용한다. 제안된 방식은 객체지향 방식의 부재를 표현함에 있어서 연결 부재간의 상관관계를 부재와 부재간의 관련 파라미터들 사이의 결합규칙을 적용함으로써 설계의 오류를 최소화 하도록 지원할 수 있다.

A software GNSS signal generator for the GPS L1/L2/L5 and Galileo E1/E5 signals is proposed in this paper. And this signal generator is designed and implemented with several components by considering the reuse and expansion of components for similar GNSS signals. The characteristics of the reusability of the components are confirmed with the carrier generation and the band-pass filter components. And the functionality of the GNSS multi-band IF signal generator is validated by using the commercial software GPS L1 receiver, and the performance of signal acquisition, tracking and accuracy of horizontal position error are analyzed for this validation. As a result, the GPS L1 signal generator operates successfully and it could be expected that other signal generators also operate well because most of components are the same as those of the GPS L1 signal generator.

객체지향 소프트웨어의 재사용은 사용자 관점에서 사고하도록 함으로써 기술 분업화를 가능하게 하고, 확장성과 재사용성 측면에서 개발 환경과 사용의 편리성에 대한 요구를 가장 근접하게 해결할 수 있다. 재사용의 현실화는 편리한 재사용 시스템, 특히 사용자 지향적인 검색 시스템의 제공으로 가능하다. 따라서 본 논문에서는 재사용 시스템 사용자들이 편리하고 정확하게 원하는 재사용 컴퍼넌트를 검색하고 수정하며 사용자의 관점에서 새롭게 조립할 수 있는 다중 템플리트 뷰(Multiple-Template Views : MT-Views)를 개발하였다. MT-Views는 혼합형 검색 방법에 따른 유사성 평가를 사용하여 재검색의 정보를 제공하므로써 검색의 효율성을 기하며 미숙한 사용자에 대한 편의와 검색된 부품의 이해를 위한 충분한 정보를 제공한다.

Radish is a common vegetable consumed in Korea, Japan, and China. Radish Breeding has been conducted based on morphological properties, such as shape and color. Recently, physicochemical properties of radish are attracting more attention from breeders to develop cultivars for the retail market. In this study, major components of radish were determined and their relationship with textural property analyzed. Sixty-six radish cultivars were selected and divided into white head (WH) and green head (GH) according to their head color. The cutting forces of GH and WH groups were $2.17{\pm}0.34kg$ and $2.31{\pm}0.36kg$, respectively (P > 0.05). The starch contents of GH and WH were $3.75{\pm}0.39g\;per\;100g$ (dry basis) and $4.24{\pm}0.62g$, respectively. Cellulose contents in both groups were similar at 12.3-12.4 g per 100 g (dry basis). Pearson correlation coefficients between cutting force, cellulose content, and starch content ranged from -0.33-0.326 which does not demonstrate any strong correlation between these components. Therefore, no relationship was found between the cutting force and the starch content or the cellulose content for the cultivars analyzed in this study. As the first intensive study on the texture and the major components of radish, these results could provide valuable information for radish breeding if further studies on taste and nutrient components are conducted.
