Objectives : The present study purposed to compare the antioxidant effect, anti inflammatory effect and cancer cell multiplication inhibition effect of Fructificatio Inonoti Obliqui aqueous extract according to extraction temperature. Methods : We medicated animal models, which had experimental oxidation, with Fructificatio Inonoti Obliqui total extract and $50^{\circ}C$ low temperature leachate, and performed hematological analysis and blood chemical analysis with measuring SOD, GSH, catalase, NO and MDA content in the liver. In addition, we made comparative observation of anti inflammatory effect and anti-cancer effect. Results : Compared to the control group, both the group medicated with Fructificatio Inonoti Obliqui total extract and with $50^{\circ}C$ low-temperature leachate were found to decrease the number of thrombocytes in blood plasma and NO content while to increase SOD activity and catalase activity significantly. Both groups also showed anti-inflammatory effect against THP-1 cells and a multiplication inhibition effect against liver cancer cells and stomach cancer cells significantly. Conclusions : Both Fructificatio Inonoti Obliqui total extract and Fructificatio Inonoti Obliqui $50^{\circ}C$ low-temperature leachate have significant antioxidant effect, anti inflammatory effect and anti cancer effect.

This study was performed to observe the effects of dietary fat levels and sources on lipids contents and cellularities of liver, brain, and adipose tissue of early weaned rats. Male Sprague-Dawley rats were prematurely weaned from postnatal 17th day with the experimental diets differ in fat levels : low(5%), medium(10%), high(20%) and fat sources : butter, soybean oil, butter＋ soybean oil. On the postnatal 29th day, contents of total lipid, triglyceride, cholesterol and phospholipid of serum, liver, brain and adipose tissue were determined, and DNA was determined to assess the cell growth. Rats early weaned fed high fat diet showed lower total lipid and triglyceride levels in serum and liver than those fed medium or low fat diet Rats early weaned fed high fat diet had adipocytes of fewer number, but larger size than those of rats fed low or medium fat diets. Rats early weaned fed soybean oil diet had more adipocytes thu those fed butter diet. Rats normally weaned to commercial chow diet showed lower total lipid, triglyceride, and cholesterol levels in serum and liver, had fewer adipocytes than all early weaned rats except for rats fed high fat-butter diet. These results suggest that high fat-butter diet is ideal weaning diet at early weaning.

This research represents an attempt to study the postoperative results among 32 patients who underwent complete resections of primary lung and involved mediastinal lymph nodes between January 1988 and June 1993. Ages ranged from 34 to 73 years with a mean age of 51.31 $\pm$ 8.17 years. There were 29 male patients[90.6%]. Left lung cancers were more frequent than right lung cancers. There were 19 cases of left lung cancers accounting for 59.4% of the total lung cancers. The difference, however, was insignificant. There was no T1 lesion. T2 and T3 lesions were 21[65.6%] and 11 cases[34.4%], respectively. As for cell type, squamous cell carcinomas were reported in 25 cases making up 78.1% of the cell types. Pneumonectomy was conducted on 20[62.5%] cases. Lobectomy and sleeve lobectomy were conducted on 12[37.5%] cases respectively. Mediastinal lymph node involvemednts were most frequent in subcarinal lymph node[9/13] among right lung cancers, while subaortic lymph noce[12/19] was most frequent among left lung cancers. Postoperative complications were reported in 18.9% of the total cases, including 2 cases each of paralysis of the recurrent laryngeal nerve and 1 case each of chylothorax and pyothorax. They were more frequent among patients who underwent pneumonectomy. The operative mortality stood at 3.1% with 1 patient who underwent pneumonectomy dying of pulmonary edema. The 1-year and 5-year survival rates were 50.8% and 30.1%, respectively. Patients treated with squamous cell carcinoma, involvement of single level mediastinal lymph node and lobectomy showed a higher level of survival. These fidings suggest that a long-term survival can be expected of a considerable number of N2 non-small cell lung cancer patients with a selective complete surgical resection of primary lung cancers involved mediastinal lymph nodes.

Oxygen consumption has been regarded as a useful indicator for assessment of mammalian embryo quality. This study was performed to investigate whether oxygen consumption reflects morphological grade of in vivo derived bovine blastocyst-stage embryos (blastocyst). The oxygen consumption of in vitro produced blastocyst was compared to its total cell number. In addition, pregnant rate was measured after transplantation of in vivo blastocysts with different oxygen consumption. The quality of blastocyst collected on day 7 after artificial insemination was categorized as grade I and II (G I and G II) based on microscopic observation of the morphology. Oxygen consumption of blastocyst was measured using a scanning electrochemical microscopy (SECM) and total cell number of in vitro blastocyst was enumerated by counting cells stained by propidium iodide. Pregnancy of recipient cow was confirmed with rectal palpation after 60 days of embryo transfer. The oxygen consumptions of G I blastocysts were significantly higher than those of G II blastocysts ($10.2{\times}10^{15}/mol\;s^{-1}$ versus $6.4{\times}10^{15}/mol\;s^{-1}$, p<0.05). Total cell numbers of in vitro blastocysts were 74.8, 90.7, and 110.2 in the oxygen consumption of below 10.0, 10.0~12.0, and over $12.0{\sim}10^{15}/mol\;s^{-1}$ respectively. Total cell number was significantly increased in embryos with high oxygen consumption (p<0.05). Pregnant rate in recipient cow was 0, 50, and 85.7% in the transplantation of embryo with the oxygen consumption of below 10.0, 10.0~12.0, and over $12.0{\times}10^{15}/mol\;s^{-1}$, respectively. These results suggest that measurement of oxygen consumption may help increase the pregnant rate of bovine embryos.

In this paper, we consider the femto users and their mutual interference as graph elements, nodes and weighted edges, respectively. The total bandwidth is divided into a number of resource blocks (RBs) and these are assigned to the femto user equipment (FUEs) using a graph coloring algorithm. In addition, resources blocks are assigned to the femto users to avoid inter-cell interference. The proposed scheme is compared with the traditional scheduling schemes in terms of throughput and fairness and performance improvement is achieved by exploiting the graph coloring scheme.

A total of 94 taxa were identified from the Southern Ocean, 140-148 $^{\circ}E$ and 40-53 $^{\circ}S$, as an early austral summer phytoplankton. They were 53 diatoms, 37 dinoflagellates, 2 silicoflagellates, 1 prymnesiophyte, and 1 coccolithophorid. Integrated cell numbers of nanoplankton dominated microphytoplankton from 8 stations, especially from Subantarctic zone, but integrated biomass was lower than microphytoplankton. Integrated cell numbers of diatoms dominated dinoflagellates, coccolithophorids, and prymnesiophyte, but integrated biomass of microphytoplankton were dependent to the biomass of dinoflagellates except north of the Subtropical convergence zone and south of the Antractic convergence zone. Phytoplankton community changed across the fronts and 3 different communities were observed. Fronts seem to influence on the phytoplankton community from the west Pacific Sector of the Southern Ocean.

본 논문에서는 기존의 Smoothing Scheme의 문제점을 개선한 새로운 WRR 셀 스케줄링 알고리즘을 제안한다. 제안된 셀 스케쥴링 알고리즘에서는 현재 라운드에 서비스되는 VC의 큐가 비어있을 경우 모든 VC들 중에서 할당된 가중치와 버퍼의 길이의 차이가 가장 큰 VC를 서비스한다. 이렇게 함으로써 대역 할당의 효율이 증가하는 결과를 가져온다. 또한, 모든 실시간 트래픽을 서비스한 후에 남은 멀티미디어 서비스 대역을 비 실시간 트래픽에 할당할 수 있다. 한 사이클 안에 평균 서비스 수가 증가하고 많은 셀을 서비스하게 됨으로써 총 버퍼 길이도 감소한다.

This paper describes a near-optimal standard cell layout strategy which consists of three consecutives steps` partition, placement, and routing. In the partition step, a given network is torn apart into many subnetworks such that each subnetworks contains as many cells as possible with minimum interocnnections between subnetwork. In the placement step, the conventional string placement algorithm was modified. Also, bonding pads were placed such that their connections to the related cells are shortest. As a result for the tested example, the placement time was saved by 60% and the total routing lengths were saved by more than 20% and substantial improvements in the number of feed-through cell and the track density were obtained. The layout program is coded in PASCAL and implemented on a VAX 11-750/UNIX computer.

Laver-wrapped rice and laver-wrapped rice containing a vinegar blend (vinegar:sugar:water:salt = 5:2:2:1) were prepared and their degrees of aging from 10 to $30^{\circ}C$, total cell numbers, and total coliforms were examined and compared. The total cell numbers of the laver-wrapped rice increased to 1 log cfu/g at 36 hours, and the total cell numbers of the laver-wrapped rice with vinegar had increased to within 48 hours. At $20^{\circ}C$ for 24 hrs, the total cell numbers for the laver-wrapped rice had increased to 5 log cfu/g: whereas trhe total cell numbers of the laver-wrapped rice with vinegar(5ml of vinegar marinade mixed into 100g of steamed rice), stored at the same conditions had not increased. In the vinegar-marinated rice (2ml/100g rice), microorganisms appeared at 18 hours. However, at the concentration of 5ml/l00g of rice, microorganisms were not observed at 24 hours. Coliforms did not appear in the laver-wrapped rice nor in the laver-wrapped rice with vinegar(prepared at 10ml/100g) until 48 hours. When stored at 10 and $20^{\circ}C$, no microorganisms were found in the laver-wrapped rice with vinegar until 48 hours, respectively. However, at $30^{\circ}C$, microorganisms were observed in the laver-wrapped rice from 24 hours, and from 48 hours in the laver-wrapped rice with vinegar. These results suggest that laver-wrapped rice should be consumed within one day. The number of microorganisms inside the laver-wrapped rice reached 6 log cfu/g by 24 hours, but the increase in the laver-wrapped rice with vinegar was slower. The aging(% damaged starch) of the laver-wrapped rice with vinegar(5ml/100g the rice) stored at $20^{\circ}C$ was reduced, with 3% damaged starch at 24 hours. Consumer evaluations revealed that the laver-wrapped rice prepared with 5ml of the vinegar blend received higher scores for flavor, taste, texture, and overall acceptance as compared to the control. In particular, significantly higher scores were given for taste, texture, and overall acceptability. In summary, the laver-wrapped rice with vinegar had an extended shelf-life(more than 1 day) at storage temperatures of $20-30^{\circ}C$, as well as reduced retrogradation. In addition, based on consumer evaluations, adding vinegar to laver-wrapped rice laver is effective for increasing overall acceptability.
