This paper studies the relationship between SCM(Supply Chain Management) metrics and corporate value (Tobin's Q) for manufacturing and wholesale/retail firms in Korea. Specifically, the multiple regression analysis is used to investigate the relationships 1) between inventory level, inventory turns, and days of inventory and Tobin's Q and 2) between cash-to-cash (C2C) cycle time including its components such as days of inventory, days sales outstanding, and days payable outstanding and Tobin's Q. The results indicate that there exist statistically significant negative relationships between inventory levels and days of inventory (DOI) and Tobin's Q. Also, we found that there exist commonly known negative correlations between days of raw materials inventory and days of work in process (WIP) inventory and Tobin's Q. For the C2C cycle time, we found that there -exists a statistically significant negative relationship between the C2C cycle time and Tobin's Q. Also, we found that there exist commonly known correlations between the two components of C2C cycle time and Tobin's Q such as the negative for DOI and days sales outstanding. This study clearly shows the negative relationship in general between inventory levels and corporate value and between C2C time and corporate value, and this kind of result has not been found by previous studies in Korea.

Recently firms which have been using traditional VAN-EDI are adapting Web-EDI at very rapid pace. Based on the Internet, Web-EDI is easier to install, is cheaper and more accessible than VAN-EDI. Web-EDI establishes an electronic hierarchy as a type of Inter-Organization Information System. An electronic hierarchy connects two legally separate firms in an electronically mediated relationship. The primary reasons for establishing an electronic hierarchy is to improve the flow of materials and information between firms. This paper suggests two hypotheses that describe the possible impact of Web-EDI on firms in the Web-EDI network, and empirically tests them using data from a case study based on a discount store. The result is as follows. First, the more a firm utilizes information shared through Web-EDI, the higher the inventory turns. Second, a higher level of information sharing does not necessarily increase the inventory turns of Web-EDI adopters who are coerced to implement the electronic networks by the champion. These findings imply that the operational performance of Web-EDI adopters can be improved only when the firms intensively utilize the information shared through Web-EDI for their business processes.

We attempted to empirically analyze the supply chain performance of Korean companies. We utilized the supply chain performance metric of SCOR(Supply-Chain Operations Reference-Model) which has been developed by the Supply Chain Council. We especially focused on the supply chain asset performance using the currently available accounting database of Korean companies. Cash-to-cash cycle time, inventory days of supply, and asset turns were analyzed for 621 Korean companies during the last 5 year period 1997-2001. We compared the performance by industry type and company size. In addition, we compared the cash-to-cash cycle time of Korean companies with global companies.

Motivated by the open access movement, research institutions are building Institutional repositories for a nation-wide knowledge distribution infrastructure. IKIS (Institute Knowledge Inventory System) was proposed to integrate materials produced by government-sponsored 23 institutions of the economic, social and human fields, to contribute for policy-making in national agenda and to proffer services to a people. As IKIS project goes on. the project turns out to be slower than planned especially In terms of building up content and improving system functions. This study aims to investigate the methods for promoting the system in terms of management and system developments using multiple research methods such as surveys and interviews. Five issues including budgets and marketing are proposed for the management strategies, whereas three ones Including content and system performance improvements are suggested for the system development. The study results can be utilized as guidelines for managing university and school repositories as well as IKIS.

Purpose - Today's world is rapidly changing due to swift changes in organization's infrastructures and supply chain is becoming an important factor which affects the organization's global competitiveness. Research design / data / methodology - Researchers indicated that environment uncertainty is considered an external driving force to establish a unique supply chain. Market competition, reducing the gap of performance and quality between the products are compelling the practitioners and researcher to change the paradigm of managing the business processes effectively and efficiently. Results - In old times, supply chain of any organization was measured on the basis of inventory turns, defect rats, lead times, stock buffering and service level. But, Lee H.L. in 2004, published an article in Harvard Business Review who proposed three A (Adaptable, Agile and Aligned) termed as "Triple-A" of successful supply chain. Conclusions - He claimed that organizations can compete through the creation of Triple-A supply chain. Hence, the basic aim of this review paper is to develop basic insights regarding what is Triple-A of supply chain, its importance and functioning in today's competitive world.

Most companies in automobile part industry need a SCM (Supply Chain Management) system under the cooperation with suppliers for assembling a automobile. Automobile part industry has a industry feature of hierarchical structure like 1st, 2nd, 3rd vendors. Recently, new cases to implement RFID (Radio Frequency Identification) technology appear in various areas required for integrated information system. Especially, supply chain environment in automobile part industry turns toward ubiquitous computing environment. Most companies in automobile part industry are interested in implementing RFID-based supply chain management system, which makes them shorten the business process, share the transaction information, and enhance the collaborative relationship between trading partners. This paper intends to implement RFID technology in the physical distribution area of automobile part industry such as warehousing, delivering, inventory management. The purpose of this paper is to improve the collaborative relationship of supply chain network using RFID applied to u-SCM system in ubiquitous computing environment. The contribution of this paper is to suggest a new system approach to transform existing business process into new business process through designing and implementing a RFID based SCM system using UML techniques.

The authors studied neuroticism, using Eysenck's Maudsley Personality Inventory (MPI), in 3,893 male college students and 1,976 female college students of Yeungnam University. There was significant difference in the mean averages of total neuroticism scores between male and female students, male students scored $13.45{\pm}7.44$, female students scored $16.89{\pm}7.19$. The items relating to (16) Do you sometimes feel happy, sometimes depressed, without any apparent reason? (38) Do you daydream a lot? (1) Do you have dizzy turns? (2) Do you get palpitations or thumping in your heart? and (35) Do you worry about your health? were scored highly in male, and the items relating to (16) Do you sometimes feel happy, sometimes depressed, without any apparent reason? (1) Do you have dizzy turns? (38) Do you daydream a lot? (8) Do you worry too long over humiliating experiences? (9) Do you consider yourself rather a nervous person? were scored highly in female. Three hundreds and ninety eight male students (10.3%) showed seriously high neuroticism scores of 24 or higher, while 256 female students (13.0%) showed high neuroticism scores of 26 or higher. In a comparison between male students in different school grades, freshman showed the highest level of neuroticism scores. Among the psychosocial factors, there were strong tendencies toward higher neuroticism scores in the students who were dissatisfied with their colleges or departments, and who had pessimistic views of self-image in the past, present, or future in both groups. The male students whose educational fees were paid by their parents, and whose spending money per month was under 10,000 won, showed higher neuroticism scores. The female students whose educational fees were paid by their brothers or sisters, and whose maturation locations were U-P, and who resided in dormitory or other residencies, showed higher neuroticism scores.
