The water extracts of 82 Korean medicinal herbs were prepared and were examined for the binding affinity on the glycine binding site of NMDA (N-methyl-D-aspartate) receptor prepared by the synaptic membranes from the forebrains of male Sprague-Dawley rats. Among the tested, the extracts of Dioscoreae Rhizoma, Hoveniae Semen cum Fructus, Astragali Radix, Armeniacae Semen, Huttuynia cordata Herba, Acanthopanacis Cortex, Aurantii nobilis Pericarpium, Phellinus linteus, Amomi Fructus, Artemisiae capillaris Herba, Polyporus, Agastachis Herba and of Galli Stomachichum Corium were found to exhibit significant competitions with $[^3H]-MDL$ 105,519 for the glycine specific binding site of NMDA receptor in a dose dependent manner, respectively.

Reproductive biology of the purplish Washington clam, Saxidomus purpuratus was investigated based on the samples captured in Jinhae Bay, the East China Sea from January to December 2002. The gonad index (GI) began to increase in January, reached the maximum value in March. The reproductive cycle of this species can be divided into five successive stages: the early active stage (from November to January), the late active stage (from December to February), the ripe stage (from February to May and October), the spawned stage (from May to December), and inactive stage (from November to December). The spawning period was from April to December, and the main spawning occurred between June and August. The shell length at 50% group maturity was estimated to be 71.85 mm. The Sex ratio of this species was not significantly different a 1:1 sex ratio (P > 0.05). 개조개 표본은 동중국해의 진해만에서 잠수선에 의해 어획된 것을 2002년 1월부터 12월까지 매월 120개체씩 채집된 것이다. 생식소 발달단계는 비활성기 (11월-12월), 초기활성기 (11월-이듬해 1월), 후기활성기 (12월-이듬해 2월), 성숙기 (2월-5월과 10월), 산란기 (4월-12월) 등 5단계로 구분되었다. 주산란시기 6월부터 8월까지이었다. 성숙각장은 71-85mm로 추정되었다. 암컷과 수컷 성비는 유의한 차가 없었으므로 1:1이었다.

Purpose: This study examined the food composition of four raw and boiled domestic potato cultivars: Superior, Dejima, Bora Valley and Rose. Methods: Proximate composition (moisture, protein, ash, dietary fiber and fat), minerals (calcium, phosphorus, iron, potassium, sodium and magnesium) and vitamins (thiamine, riboflavin and niacin) were analyzed in the study. Results: In this study, it was observed that the moisture contents of raw and boiled Bora Valley potato were 83.74 g/100 g and 81.57 g/100 g, respectively, which was highest among the studied cultivars. The protein content of the raw and boiled Rose potato (12.23 g/100 g and 11.02 g/100 g) was higher than that of the other cultivars. Protein contents of boiled Bora Valley and Rose potatoes were significantly lower than those of their respective raw samples. The potassium, phosphorus and sodium contents of Bora Valley potato were 2,397.69 mg/100 g, 389.13 mg/100 g and 14.12 mg/100 g, respectively. In case of raw potato, the calcium, iron and magnesium contents of Dejima potato were 51.52 mg/100 g, 3.21 mg/100 g and 137.62 mg/100 g, respectively, which were the highest values among the tested potato cultivars. Total dietary fiber content of Dejima potato was 14.78 g/100 g, which was the highest level. The dietary fiber contents of four cultivars of potatoes were lower after boiling. Thiamine content was highest in the Bora Valley potato (0.43 mg/100 g). Riboflavin contents of the Rose potato was 0.35 mg/100 g, which was higher than that of the others. Conclusion: Overall, four cultivars of raw and boiled potatoes had enhanced food composition. Therefore, these potato cultivars are expected to be highly valuable food items for the development and application of functional foods.

컴퓨터를 이용한 각종 정보처리 기기들이 대중화되고 다양한 텔리매틱 서비스에 대한 수요가 점차 늘어감에 따라 종합정보통신망(ISDN)에 대한 필요성이 높아지고 있다. ISDN으로의 전개에 따라 현재의 공중통신망의 유지보수와 다른 형태의 유지보수 체계의 정립이 필요하다. 본고에서는 ISDN의 가입자 액세스 및 공통선 신호방식의 채택에 따른 유지보수에 대해 고찰하였다.
수종 생약추출물의 muscarin성$(M_1\;type)$ acetylcholine 수용체$(mAChR-M_1)$에 대한 친화력 검색

The water extracts of 82 Korean medicinal herbs were examined for the binding affinity on the recombinant human muscarinic acetylcholine receptor subtype 1 $(mAChR-M_1)$ produced from the CHO (Chinese Hamster Ovary) cell line. Of those tested, the extracts of Coptidis Rhizoma, Phellodendri Cortex, Hedyotis Herba and of Terminariae Fructus were found to exhibit a significant competition with $[^3H]$ N-methyl-scopolamine for the specific binding to $mAChR-M_1$ in a dose dependent manner, respectively.

This paper focuses on lossy medical image compression methods for medical images that operate on three-dimensional(3-D) irreversible integer wavelet transform. We offer an application of unbalanced tree structure algorithm to medical images, using a 3-D unbalanced wavelet decomposition and a 3-D unbalanced spatial dependence tree. The wavelet decomposition is accomplished with integer wavelet filters implemented with the lifting method. We have tested our encoder on volumetric medical images using different integer filters and coding unit sizes. The coding unit sizes of 16 slices save considerable dynamic memory(RAM) and coding delay from full sequence coding units used in previous works. If we allow the formation of trees of different lengths, then we can accomodate more transaxial scales than three. The encoder and decoder can then keep track of the length of the tree in which each pixel resides through the sequence of decompositions. Results show that, even with these small coding units, our algorithm with certain filters performs as well and better in lossy coding than previous coding systems using 3-D integer unbalanced wavelet transforms on volumetric medical images.

An implementation of modified stereo matching using efficient belief propagation (BP) algorithm is presented in this paper. We do recommend the use of the simple sobel, prewitt edge operator. The application of B band sobel edge operator over image demonstrates result with somewhat noisy (distinct border). When we adopt the only MRF + BP algorithm, however, borders cannot be distinguished due to that the message functions in the BP algorithm is just the mechanism which passes energy data to the only large gap of each Message functions In order to address the abovementioned disadvantageous phenomenon, we use the sobel edge operator + MRF + BP algorithm to distinguish the border that is located between the similar message data. Using edge information, the result shows that our proposed process diminishes the propagation of wrong probabilistic information. The enhanced result is due to that our proposed method effectively reduced errors incurred by ambiguous scene properties.
