Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginsengvarieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-groundroots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas theproportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus theGumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is70.6 g for 6-yr-old roots. Its yield is 2.9 kg/1.62m2 and the rate of heaven- and earth-grade product is20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and thesurvival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of redginseng, is 95.1 mmol/g and greater than the 30.8 mmol/g of Chunpoong in 6-yr-old plants. Sunun andCheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resourcesand breeding. Jang-Ho Lee

In this paper a time reduction algorithm for large vocabulary speech recognition system has been studied. TDNN(Time Delay Neural Network) was used to classify vowel using phonetical fetures. To increase performance of vowel classification, modular TDNN architecture associated with 2 states input layer has been suggested.

In this paper, the effective multi-processor architecture of 32 bit floating point digital signal processor(TMS 320C 30) has been studied. This multiprocessor system consists of one master module and several process modules. Master module can communicate with host computer or sample analog input signal and stores the samples in common memory. Each process module can access common memory module under the control of common bus arbitration logic and detailed circuits of this arbitration logic has been studied. In addition, local memory decode part, common memory decode part and wait signal generation logic have been suggestd.

측면연마된 광섬유와 광기능성 색소가 분산된 평면도파로 결합기를 이용한 새로운 형태의 자외선센서를 제작하여 그 특성을 측정하였다. 자외선 조사에 의해 유효굴절률이 변화하는 광변색성 색소가 분산된 폴리머를 평면 도파로 재료로 사용하였다. 박막 광도파로는 광변색성 색소인 스파이록사진을 사용하였다. 자외선 조사시간을 20초, 30초, 40초로 증가시켰을 경우 센서의 파장응답은 1.44nm/mW, 1.64nm/mW, 1.78nm/mW였고 1550nm 파장에서 센서의 90% 복귀시간은 100초로 나타났다. In this paper, we investigated a novel UV sensor using evanescent field coupling between the side polished fiber and photo-functional polymer waveguide. It was found that resonant wavelength shifts occur due to variation in the refractive index of polymer planar waveguide for its photo-functional properties on exposed UV. Spiroxazine (photochromic dye) was used as the planar waveguide. The resonant wavelength response were exhibited at 1.44 nm/mW, 1.64 nm/mW, and 1.78 nm/mW when UV irradiations were exposed for 20 seconds, 30 seconds, and 40 seconds, respectively. The recovery time of sensor was independent of UV exposure power and 90% recovery time was 100 seconds.

The purpose of this study is to analyze the design preference according to the body consciousness for 20∼26 years old male. The consciousness of body size and the satisfaction with body proportion were investigated. And the relationship between the body consciousness and the design preference was analyzed. Most subjects thought their body size was proper generally and their body proportion was proper or a little unsatisfied. The subjects preferred 'Round neckline', 'loose sleeve', and 'loose and long tops'. They didn't like the style that tops are under pants on the waist. They also preferred 'loose and long pants'. When the subjects chose clothing design, especially 'V-neckline tops' and 'short pants', they considered their height. They also considered their girth size and it meant they thought much of looseness. There was not any preference in clothing design according to the consciousness of height. The most significant relationships between the size consciousness and the preference in design was found in tops more than pants. The higher satisfaction with their body proportion was connected with the higher preference in some design. From all these results, it was found that the preference of clothing design could vary according to the consciousness of body size. The results from this study could give the important tips to improve the satisfaction with the clothing for each person.

현재 의료진단, 화학공정의 모니터링이나 환경공학적 감시 및 제어 등의 분야에서 사용되고 있는 기존의 센서는 고가이며 용적이 클 뿐만 아니라 분석시간이 길고 사용하기 까다로운 것 등 여러 가지 문제점이 있다. 또한 측정환경에 영향을 주지 않을 만큼 충분히 작으며 빠른 분석시간을 가진 센서를 필요로 하고 있다. 본 연구에서는 기존의 센서들의 난점을 극복할 수 있는 새로운 형태의 FET형 전해질(electrolyte : H^+, K^+, Ca^2+, Na^+)분석 시스템, 용존가스(O_2, CO_2)분석 시스템의 개발을 중점적으로 추진하며, FET형 압력센서, 습도센서, 방사형 온도센서 등의 개별 FET형 센서에 관한 연구도 병행하고자 한다. Recently various kinds of sensors have been developed, being applicated to their own purpose. There are lots of difficulties to apply them to measurements in which the real-time monitoring is required without disturbing the surrounding environment. FET type semiconductor sensors, fabricated by the semiconductor integration technologies, have many advantages for their miniaturization, standardization, mass-production and in vivo/in situ monitoring. They also hold a very proper configuration for multi-functional sensors or integrated smart sensors, and wide availability by forming various kinds of physical or chemical sensing materials onto their sensing gates.

<P>This study investigates a spin-coating method for modifying the surface properties of a poly(ethylene-alt-maleic anhydride) (PEMA) gate insulator. The 60 nm-thick PEMA thin film exhibits excellent electrical insulating properties, and its surface properties could be easily modified by surface grafting of octylamine. Due to surface treatment via spin-coating, the surface energy of the PEMA gate insulator decreased, the crystal quality of the organic semiconductor improved, and consequently the performance of low-voltage organic thin-film transistors (TFTs) was enhanced. Our results suggest that the surface treatment of the PEMA gate insulator could be a simple and effective method for enhancing the performance of organic TFTs.</P>
