The effects of bulbocapnine, an aporphine isoquinoline alkaloid, on dopamine content in PC12 cells were investigated. Bulbocapnine decreased the dopamine content dose-dependentl y (39.2% inhibition at 2O${\mu}$M for 24 hr). The $IC_{50}$ value of bulbocapnine was 22.7${\mu}$M. Dopamine content was lowered at 6 hr after exposure to bulbocapnine. And then, the decreased dopamine level was almost maintained at 36 hr and recovered to the control level at about 60 hr. Tyrosine hydroxylase, the rate limiting enzyme in the catecholamine blosynthetic pathway, was also inhibited at 20${\mu}$M of bulbocapnine by 23.1% relative to control. We, therefore, hypothesized that the inhibition of tyrosine hydroxylase by bulbocapnine with a single treatment might be partially contributed to the decrease in dopamine content in PC12 cells.

Production of medicinal soybean [Glycine max (L.) Merrill], characterized with black seed, white stripe at hilum border, yellow cotyledon and small seed, is increasing with increasing consumption. The objective of this study was to investigate the chemical composition of medicinal soybean seed and to provide basic information, for the characterization of these soybeans among genetic resources. Forty-four lines of medicinal soybeans collected from Korea and two control cultivars, 'Hwangkeumkong' (Yellow seed coat) and 'Geomjeongkong l' (Black seed coat) were planted at the Research Farm of the College of Natural Resources, Korea University, located at Namyangju City on May 25, 1996. Seeds of these lines were harvested at full maturity and analyzed for protein, oil, sugar, starch and mineral contents. Mean protein and oil content of the medicinal line seeds were 42.6 and 16.1%, respectively, and those of the control cultivars were in the middle range for protein and oil content. However, sugar and starch content of the medicinal line seeds appeared to be in the lower range of the distributions compared to the control cultivars and were 10.0 and 1.68%, respectively. Mean P, K, Ca, and Mg contents of the seeds of medicinal soybean lines were 15.9, 21.5, 3.11, and 2.81 mg/g, respectively, indicating that these lines had higher P, K, and Mg and lower Ca contents when compared to the control cultivars. Mean Na and Fe contents were 671 and 224 mg/kg, respectively, showing lower Na and similar Fe contents. The observed results provided that chemical compositions of medicinal soybean were, on average, different from those of the general soybean cultivars.

Three kinds of grape yakju (Kyoho, Campbell and Moru) and grape-free control were fermented with rice using koji of Aspergillus kawachii as a fermenting agent, and their fermentation characteristics were investigated. For the three yakju, reducing sugar content decreased slowly over 2 days fermentation after an initial rapid decrease. In case of Brix, the reducing sugar content increased gradually after increasing rapidly during the first 2 days of fermentation. The Kyoho and Moru groups displayed a gradual increase in reducing sugar content after an initial 2-day decrease, and the sugar content of the Campbell group increased gradually during fermentation. Uniformly, pH increased gradually after an initial 2-day decrease, however total acid increased continuously throughout fermentation. Alcohol content of yakju showed almost no change after increasing until day 6 (Kyoho) of day 4 (others), with the control displaying the highest content. Control $\alpha$-amylase activity decreased gradually after an initial 2-day increase, while that of the three yakju decreased throughout fermentation. Activities of $\beta$-amylase activities paralleled the results of reducing sugar. Concerning total anthocyanin, the Moru and Campbell groups displayed a rapid increase until day 2, a decrease until day 12, and a gradual increase thereafter. While the Kyoho and control groups displayed virtually no change after an initial 2-day increase until day 12, after which a gradual increase also occurred. In concerning sensory evaluation, Moru yakju scored highest for violetness, flavor of grape, and sweet taste, and also displayed a low alcohol content. These attributed Moru yakju the preferred choice.

In order to examine the antioxidant activities of SJDBT(Sibjeondaebo-tang), the study was done through measurement of parameters such as LPO(lipidperoxidation), GSH(glutathione), SOD(superoxidation dismutase), catalase, GOT, GPT, ALP. The results were obtained as follows: For the weight changes, the kidney and testis of group given SJDBT showed decrease in the weight compared to the control group, and the left cerebrum, right cerebrum, cerebellum and liver of group given SJDBT showed increase. But the changes were not significant. The left cerebrum and right cerebrum of group given SJDBT showed significant decrease in the content of LPO compared to the control group, and in the activity of SOD and catalase showed significant increase. The cerebellum of group given SJDBT showed significant decrease in the content of LPO and GSH compared to the control group, and in the activity of SOD and catalase showed significant increase. For the changes of LPO, GSH in the liver, the group given SJDBT showed significant decrease in the content of LPO and GSH compared to the control group, and in the activity of catalase showed significant increase. For the changes of LPO in the kidney, the group given SJDBT showed significant decrease in the content of LPO compared to the control group. For the changes of LPO, GSH and the activity of SOD, catalase in the testis, the group given SJDBT showed significant decrease in the content of LPO and GSH compared to the control group, and in the activity of SOD and catalase showed significant increase. From above results, the antioxidant action of SJDBT is effective. And it is expected to be necessary to the study of the mechanism in the antioxidant of SJDBT.

Sugar concentration, starch concentration, water content, and dry weight in fruit tissue of kiwifruit (Actinidia deliciosa) were investigated when the fruit growth was being restricted with ø43 mm and ø52 mm acrylic sleeves. Fruit fresh weight, dry weight, and water content of both the sleeve treatment fruits did not increase as much as those of control fruit did. The water content stopped increasing for treatment fruit of acrylic sleeves at fruit growth stage III. The total sugar concentration suddenly increased and then decreased to the level of control fruit in both acrylic sleeve treated fruit. At that time, starch concentration was not shown to be lower tendency than that of the control fruit, and dry matter percentage was not different between treatment fruit and control fruit. Therefore, the total sugar concentration increment at the growing fruit restricted with acrylic sleeves may be effective for water content decrement in fruit tissue.

Usage control models are the new breed of access control models that allow description of comprehensive policies for usage of protected content. In this paradigm, decisions regarding access to objects are not limited to request time only. It is coupled with the usage of the protected objects and becomes a continuous process carried out in parallel to the usage. The realization of usage control has been a long standing research problem to overcome the issue of loss of control in secure document dissemination. With the emergence of cloud computing, documents are stored in the cloud, the document viewers and editors themselves reside in the cloud and are accessed from thin clients such as browsers. We note that such scenarios provide an ideal opportunity for the realization of usage control for securing the usage of documents based on the stakeholders' policies. In this paper, we proposed Multimedia Content Management (MCM) for a better realization multimedia content in the cloud based applications. We designed a robust architecture to provide fine-grained control over usage of protected objects through the use of emerging cloud computing paradigm. We present the design principles for this realization and discuss our proposed architecture.

A study was conducted to evaluate nutritional value for twenty-one pork muscles. Ten market-weight crossbred pigs (five gilts and five barrows) were used for evaluating proximate chemical composition, cholesterol, total iron, calorie and fatty acid contents. As preliminary analysis revealed no noticeable sex effect, pooled data from both sexes were used for the final analysis. M. rectus femoris had the highest moisture content, while m. latissimus dorsi was lowest in moisture content (p<0.05). Protein content was highest for m. longissimus dorsi and lowest for m. supraspinatus (p<0.05). The tensor fasciae and latissimus dorsi muscles contained the highest intramuscular fat (p<0.05), while rectus femoris, adductor and vastus lateralis were lowest in intramuscular fat content. When simple correlations between chemical values were computed for the pooled dataset from all muscles, intramuscular fat had significant (p<0.05) negative linear relationships with moisture (r = -0.85) and protein (r = -0.51) contents. Calorie levels were not significantly affected by fat content, while rectus femoris and latissimus dorsi muscles showed lowest and highest calorie contents, respectively (p<0.05). Polyunsaturated fatty acid content was highest (p<0.05) for both m. adductor and m. rectus femoris, while it was lowest for m. longissimus dorsi. Collectively, the current study identified a large amount of variation in nutritional characteristics between pork muscles, and the data can be used for the development of muscle-specific strategies to improve eating quality of meats and meat products.

Objective: Aim of this study was to evaluate the influence of freeze-dried acid whey addition and the use a game meat (fallow deer) on a microbial content and the biogenic amines formation in dry fermented sausages. Methods: The experiment involved dry fermented sausages made in two variants from beef and from fallow deer. Each variant was divided into five groups: control (with a curing mixture), reference (with a sea salt), sample with a liquid acid whey and two samples with the addition of reconstituted freeze-dried acid whey in different concentrations. Changes in lactic acid bacteria (LAB), Enterobacteriaceae content and biogenic amines content were determined. Results: The microbial content changes suggest that addition of acid whey slightly affected LAB content in comparison with the control and reference sample, but the addition of freezedried acid whey resulted in a reduction of Enterobacteriaceae content in the sausages from fallow deer or a similar level in the beef sausages compared with the control and reference sample. Both changes in LAB and Enterobacteriaceae content were more evident in case of sausages made from fallow deer. Addition of acid whey (liquid and a higher amount of freezedried) and use of fallow deer meat to produce the sausages resulted in a significant reduction of total biogenic amines content. Conclusion: The addition of acid whey (liquid and higher amount of freeze-dried) resulted in a significant reduction of total biogenic amines content in dry fermented sausages made from fallow deer meat.

This paper presents an adaptive rate control scheme for streaming-based content sharing service. This scheme delivers multimedia contents from a user device to another device or seamlessly redirects streaming service across heterogeneous user devices. In the proposed scheme, a streaming server adjusts video quality level according to the network and client status. Our scheme is different from other rate control schemes, because the video quality at the server is decided not only based on the available bandwidth, but also based on the device characteristics and bandwidth requirement at the access network. We also propose a bandwidth estimation method to achieve more equitable bandwidth allocations among streaming flows competing for the same narrow link with different Round Trip Times (RTTs). Through the simulation, we prove that our scheme improves the network stability and the quality of streaming service by appropriately adjusting the quality of the video stream. The simulation results also demonstrate the ability of the proposed scheme in ensuring RTT-fairness while remaining throughput efficient.
