In view of the past, the mobility of the multicast source in the mobility networks is seldom discussed in the traditional multicast protocols. It is a heavy cost for the traditional multicast protocols to reconstruct the multicast tree in the Network Mobility (NEMO) environment. This article proposes an alternative multicast protocol, referred to as Mobility-Sensitive Multicast protocol (MSM), for the NEMO environment. The MSM can be considered as an alternative version of the Multicast Listener Discovery (MLD) protocol to maintain the multicast tree in the NEMO. There are two obvious contributions for the MSM. Reconstruct mechanism could rebuild the multicast tree for the mobility of the multicast source. Multi-group suppression mechanism reduce the multicast tree maintaining cost for the mobility of the multicast members. Through the performance evaluations and analyses, the MSM has less cost to maintain the multicast tree than the traditional multicast protocols, especially for a large numbers of multicast groups. Moreover, the MSM allows the mobility of the multicast source to reconstruct the multicast tree easily.

The purpose of this paper is to show the effect of information sharing strategy on the supply chain performances. While traditional information sharing models assumed centralized stock information, recent supply chain practices often implement fully shared stock information, where real-time stock information is accessible on retailers. When retailers are competing with each other, this fully shared stock information may incur retailers' strategic order behaviors. Thus, this paper analyzes a simple two-level supply chain consisting of one warehouse and two identical competing retailers where the real time stock information is fully shared. The warehouse uses the traditional echelon stock policy. Under this environment the retailers' reorder decisions are derived using the order risk concept and the retailer competition mechanism is analyzed. Computational results show that the supply chain performace degradation in the fully shared stock information is quite significant, implying the importance of designing information sharing strategies in the supply chain design phase.

Objective: Ayurveda is a complementary and alternative medical (CAM) system that has been practiced primarily in the Indian sub·continent for 5,000 years. As need for CAM increases, interest in Ayurveda is drawing more attention in Western countries. But in Korea, understanding of Ayurveda is superficial due to a lack of information and research. In this article, we investigated not only the philosophical features of Indian Traditional Medicine, but its relationship with Korean Oriental Medicine. Methods: From April to August 2004, we sought mutual cooperation through observation at research institutes (Central Council for Research in Ayurveda and Siddha, National Institute of Ayurveda, Institute of Medical Science, Pharmacopoeial Laboratory for Indian Medicine) and performed on-the-spot surveys & discussions. Results & Conclusions: We conclude that the philosophies of Indian Traditional Medicine could extend those of Korean Oriental Medicine. Adopting some promising Indian Traditional Medicine techniques such as PanchaKarma and KsharaSutra treatments which have been shown to have efficacy and safety could contribute to the development of Korean Oriental Medicine's internal & external medical treatment. Further studies of Indian Traditional Medicine are needed.

The purpose of this study was to segment the clothing customers of new traditional market according to shopping orientation and to clarify the different clothing behaviors among segmented groups. This study may be useful for new traditional marketer to make proper marketing strategies. The subjects for the final analysis were 400 customers who visited Namdaemoon and Dongdaemoon new traditional markets. The statistics used for analysis were factor analysis, cluster analysis, Cronbach-${\alpha}$, one-way ANOVA, LSD multiple range test and chi-square by the SPSS program. The results of this study were as follows: 1. The customers of new traditional market were segmented to 5 groups (Diffidence Group, Confidence/Information Group, Active Group, Shop/Brand Loyalty Group and Planned Purchasing Group); 2. The five segmented groups were significantly different in clothing evaluation standards, shop evaluation standards, satisfaction and demographic variables such as sex, age, education and monthly spending money.

This paper uses a data mining approach to develop bankruptcy prediction models suitable for traditional (off-line) companies and electronic (on-line) companies. It observes the differences in the composition prediction models between these two types of companies and provides interpretation of bankruptcy classifications. The bankruptcy prediction models revealed the major variables in predicting bankruptcy to be 'cash flow to total assets' and 'gross value-added to net sales' for traditional off-line companies while 'cash flow to liabilities','gross value-added to net sales', and 'current ratio' for electronic companies. The accuracy rates of final prediction models for traditional off-line and electronic companies were found to be $84.7\%\;and\;82.4\%$, respectively. When the model for traditional off-line companies was applied for electronic companies, prediction accuracy dropped significantly in the case of bankruptcy classification (from $70.4\%\;to\;45.2\%$) at the level of a blind guess ($41.30\%$). Therefore, the need for different models for traditional off-line and electronic companies is justified.

The purpose of this study was is to understand how the network pharmacology databases of traditional medicine in China are established and provide suggestion for successful implementation in Traditional Korean Medicine. We searched for network-pharmacology-related TCM Databases provided on the internet, and analysed their contents. Then, we compared herbs related to Sasang with herbs of the TCM Databases. We chose 8 network-pharmacology-related TCM Databases. They shared information about compounds, herbs, formulae, drugs, targets and diseases, and provided interaction networks between these components. In comparison with herbs related to Sasang, TCMSP Database did not have information about 99 herbs in total, and 25 herbs included in major Sasang formulae. The implications and recommendations for Traditional Korean Medicine researches were discussed. Based on the results of this primary study, more related studies should be carried out in the future.

This study focused on the alcohol fermentability of traditional Nuruk, as well as yeast containing traditional Nuruk, in the production of Yakju. The fermentation performed with 30% Nuruk was effective with regard to alcohol yield. In addition, the fermentation containing 70% Nuruk showed the highest titratable acidity due to increased amounts of organic acids (succinic acid, oxalic acid, malic acid, acetic acid), which, however, negatively influenced the Yakju quality. Moreover, microbiological contamination always occurred in the fermentations using only Nuruk. In contrast, in the experiments with the yeast containing Nuruk, higher alcohol content and lower titrable acidity were obtained, independent of the Nuruk ratio used, positively effected the Yakju taste and flavor. Overall, the fermentation performed using the yeast containing 30% traditional Nuruk showed the best results for Yakju production.
