  • Object : The effects of Rehmanniae Radix(RR) on HPA Axis system and Catecholaminergic system was investigated. Methods : we performed the Forced Swimming Test(FST). Also the expression of Corticotropin -Releasing Factor(CRF), c-Fos and Tyrosine Hydorxylase(TH) was measured by immunohistochemical method at Paraventricular Nucleus(PVN), Locus Coeruleus(LC) and Ventral Tegmental Area(VTA). Results : 1. The duration of immobility in the Forced Swimming Test was significantly decreased in the Rehmanniae Radix 400 mg/kg groups in comparison with the control group(p<0.05). 2. Comparing to the control group, CRF expression was significantly decreased in the Rehmanniae Radix 400 mg/kg treated group in comparison with the control group(p<0.01). 3. c-Fos expression was significantly decreased at PVN in the Rehmanniae Radix 100 mg/kg treated group in comparison with the control group(p<0.01). 4. TH expression was significantly increased at LC in the Rehmanniae Radix 100 mg/kg and 400 mg/kg treated group in comparison with the control group(p<0.001). 5. TH expression was significantly decreased at VTA in the Rehmanniae Radix 100 mg/kg and 400 mg/kg treated group in comparison with the control group(p<0.001). Conclusion : According to the results, it can be considered that Rehmanniae Radix has antidepressant effect by showing the reduction of immobility in FST through the decreased expression of CRF, c-Fos in PVN and TH in VTA.

  • Purpose: This study investigates morphologic change of the rectosigmoid colon using a belly board in prone position and distended bladder in patients with rectal cancer. We evaluate the possibility of excluding the proximal margin of anastomosis from the radiation field by straightening the rectosigmoid colon. Materials and Methods: Nineteen patients who received preoperative radiotherapy between 2006 and 2009 underwent simulation in a prone position (group A). These patients were compared to 19 patients treated using a belly board in prone position and a distended bladder protocol (group B). Rectosigmoid colon in the pelvic cavity was delineated on planning computed tomography (CT) images. A total dose of 45 Gy was planned for the whole pelvic field with superior margin of the sacral promontory. The volume and redundancy of rectosigmoid colon was assessed. Results: Patients in group B had straighter rectosigmoid colons than those in group A (no redundancy; group A vs. group B, 10% vs. 42%; p = 0.03). The volume of rectosigmoid colon in the radiation field was significantly larger in group A (56.7 vs. 49.1 mL; p = 0.009). In dose volume histogram analysis, the mean irradiated volume was lower in patients in group B (V45 27.2 vs. 18.2 mL; p = 0.004). In Pearson correlation coefficient analysis, the in-field volume of rectosigmoid colon was significantly correlated with the bladder volume (R = 0.86, p = 0.003). Conclusion: Use of a belly board and distended bladder protocol could contribute to exclusion of the proximal margin of anastomosis from the radiation field.

  • The aim of this study was to examine price sensitivity of industrial products purchased via a group buying system and how industrial products for a group buying system differ from general industrial products, and then identify the major factors in selecting products and the important determinants in purchasing industrial products for school foodservices. The survey was conducted with 250 dietitians (teachers) in Gyeonggi-do Province, who were using industrial products for a group buying system and general industrial products. A paired t-test showed a difference in satisfaction between industrial products for a group buying system and general industrial products by factors, while statistically significant differences were found for red pepper paste, fermented soybean paste and soy sauce in all nine satisfaction factors, including product quality, packaging state, labeling, hygiene, item diversity, specification diversity, price appropriateness and supply. Moreover, analyzing price sensitivity for industrial products for a group buying system, using the PSM method with respect to the issue of high price, showed that the respondents considered that the current unit purchase prices were high for all items investigated. This study suggests that schools would purchase more industrial products for a group buying system, when the pricing of the products are considered with the purchase intention of dietitians (teachers).

  • These days we come across many wicked problems whose solutions are beyond individuals intellectual ability. These problems can be resolved through collaborative group interaction. We developed an internet-based asynchronous group interaction support system, after looking into the collaborative problem solving process and the IBIS (Issue-Based Information System) argumentation model. It has the following characteristics ; 1) it is developed based on the modified IBIS model which is a model for group interaction to resolve wicked problems ; 2) it supports both processes of seeking and comparing solutions, while most similar systems do not have a feature to support the latter process ; 3) different structures can be defined dynamically according to the purpose of group interaction, so that it could be used for collaborative problem solving in a specific domain. To show the usability of the system, we carried out an experiment, whose result is shown at the end.

  • Nowadays many people participate in online communities for information sharing. But most recommender systems are designed for personalization of individual user, so it is necessary to develop a recommendation procedure for group users, such as participants in online communities. This paper proposes a group recommender system to recommend books for group users in online communities. For such a purpose, we suggest a group recommendation procedure consisting of two phases. The first phase is to generate recommendation list for 'big user' using collaborative filtering, and the second phase is to remove irrelevant books among previous list reflecting the preference of each individual user. The procedure is explained step by step with an illustrative example. And this procedure can potentially be applied to other domains, such as music, movies and etc.

  • This study was conducted to investigate the antioxidative effects of Paeonia lactiftora Pall. (PL) seed extracts and Forsythia viridissima Lindl. (FVL) extracts on the antioxidative defense system and lipid peroxidation in the erythrocytes of rats fed a high-cholesterol diet. Sprague-Dawley male rats weighing 100 10 g were randomly assigned to nine experimental groups and fed 0.5 % cholesterol. The HC group did not receive any supplement, while the MP group was supplemented with 0.1 % methanol extract of PL seed, the MP2 group with 0.2 % methanol extract of PL seed, the EP1 group with 0.05 % ether-soluble fraction of PL seed, the EP2 group with 0.1 % ether-soluble fraction of PL seed, the MS1 group with 0.05 % methanol extract of FVL, the MS2 group with 0.1 % methanol extract of FVL, the ES group with 0.025% ethyl acetate-soluble fraction of FVL, and the ES2 group with 0.05 % ethyl acetate-soluble fraction of FVL. The experimental diets were fed ad libitum for 3 weeks. The erythrocyte SOD activity in the EP1 and EP2 groups increased 38% and 59%, respectively, when compared with the HC group, while the erythrocyte GSHpx activity in the EP1, EP2, and ES2 groups increased 30%, 31 %, and 29%, respectively, when compared with the HC group. The level of erythrocyte TBARS was significantly lower in the MP2, EP1, and EP2 groups than in the HC group, yet the level of serum TBARS was significantly lower in the all supplemented groups than in the HC group. The level of serum HDL- TBARS was significantly lower in the EP1 and EP2 groups than in the HC group, while the level of serum LDL- TBARS was significantly lower in the all the supplemented groups than in the HC group. Accordingly, the results indicated that the PL seed extracts and FVL extracts reduced oxidative damage by activating the antioxidative defense system in the erythrocytes of rats fed a high-cholesterol diet.
