Unlike the existing applicable systems, electronic commerce focuses on securing means of identifying a user and verifying data as well as controlling an access to data. It is electronic signature that is an instrument to meet security requirements inherent to electronic commerce. EC also requires a high level of reciprocity among EC-related applicable systems in addition to a strong verification of users. Therefore, security functions need to be installed in a way that supports reciprocity. Fundamental security requirements for electronic commerce are confidentiality, zero-defect, verification, endowment of rights, guarantee and privacy. A framework of information protection for the security of EC needs to be built systematically so that safety and confident in EC can be secured. AS the transaction can not be processed on line without an electronic payment system in EC, an on-line payment system intended to process the transaction money is a significant part in affecting the efficiency of EC

데이터 웨어하우스 설계에서 다차원 모델링에 관한 연구

The definition of the data warehouse which is proposed is : A corporate data warehouse is a single integrated store of data which provides the infrastructural basis for informational software applications in the enterprise. The Corporate data warehouse may be defined in terms of six key characteristics which differentiate the data warehouse from other database systems in the enterprise. (1) Available entirely for the task of making data available to be interrogated by business users. (2) Separate from the operational system in the enterprise and populated by data from these systems. (3) Integrated on the basis of a standard enterprise model. (4) Time stamped and associated with defined periods of time, i. e. calendar periods or fiscal reporting periods. (5) Subject oriented, most usually on the basis of 'Customer'. (6) Accessible to users who have a limited knowledge of computer systems or data structures. The multidimensional database systems differ from relational database systems in that they are currently highly proprietary in nature, typically do not directly support SQL, and can support significantly less volume of data than even an "average"RDBMS. However, multidimensional database systems may be an excellent option for a departmental instance if the functionality it provides is what the business requirements of the target user demand. In the coming 'Age of Information', data will not just comprise entities in a database which have got attributes and relations but data will have texture through which hidden structures and patterns can be revealed. This will fundamentally transform our understanding of information from 'something we desire to know' to 'something which could never have otherwise been knowable'.

This study is for improving the quality of cheese, which is favorable to Korean Taste. In this work, new starter cultures were used other than 2 kinds of conventionally used one. Production time, pH, and physico-chemical characteristics were checked during the maturing period. 1) In case of Physico-Chemical characteristics, The moisture contents were 46.97, 41.70, and 48.82% respectively and nacl level of 0.50, 0.58 and, 0.58 respectively in new starter culture of TA-LH, TA-LB, TA-LC. 2) Melt-ability were measured as 2.49, 1.87, 2.74 crn respectively by using new starter cultures of TA-LH, TA-LB, TA-LC. The melt-ability was also increased by matureing and showed dfferences according to the kind of start culture, and storage period(P<0.05). 3) pH of cheese were 5.50, 5.51, and 5.20 respectively by TA-LB, TA-LC, and increased slightly during maturing. 4) The Hunter color were L-Color 1.03, 2.27, and 1.22 and b-color were 6.64, 11.11, and 11.78 respectively by the TA-LH, TA-LB, and TA-LC by Chroma-meter determination(P<0.05). 5) In cheese texture change, the hardness were 13.12, 18.94, and 7.20kg/cm²respectively by TA-LH, TA-LB, and TA-LC. Cohesiveness were 0.75, 0.67, and 0.67 respectively and Springness were 0.92, 0.62, and 0.78/cm²respectively while gumminess were 9.88, 12.76, and 4.85/Kg/cm² respectively, Chewiness were 9.12, 7.85, and 3.77, respectively and parameter were different according to each starter culture. 6) In the Pizza Topping test, the browning color and Blistering size showed similar results in TA-LH, TA-LB, and TA-LC. However, The browning and blistering of TA-LH, TA-LC were reduced extremely by 4weeks maturation while no change was shown in TA-LB. 7) Using TA-LH, TA-LB, and TA-LC, the measure of FO and FOFB were increased from 4.51% to 5.84%. from 5.28% to 6.96%. and from 7.47% to 9.76% respectively following maturation date of 1, 2, 4weeks and samples were refrigerated in storage condition. The mature period and starter culture relationship also showed different characteristic in starter culture of 1, and 4weeks only, in the TA-LB starter. 8) In the scanning election micrographs, the serum channels were found enlarged according to maturation date and similar results were shown in all kind of starter culture. 9) The WSN level in the total nitrogen weight were increased from 11.16% to 13.63%, from 3.87% to 6.66%, and from 14.74% to 17.29% respectively in TA-LH, TA-LB, and TA-LC. NPN level were also increased from 2.96% to 4.74% from 4.69% to 4.92%, and from 2.81% to 4.40% respectively according to maturation period. The WSN, and NPN level showed different results by maturation period. (P<0.05) 10) FPLC After 4 weeks maturation, some change could be detected in k-Casein and β -Casein compare to just finished product. 11 ) Eletrophoresis In all cheeses of TA-LH, TA-LB, TA-LC. the 7 -Casein creation from β -Casein were detected after 4 weeks maturation. By α -Casein an band was appeared around a sl- I and the strength of separate became gradually weak. 12) Sensory test The score of flavors by maturation period were in the range of 2.95-3.75 point. The TA-LC gave lowest point at the 4weeks. While TA-LH(2weeks) gave top point of 3.73. The taste scores were lowest in TA-LC(lweek)/2.68 while top point in TA-LH(2weeks)/3.59, The Appearance showed lowest point of TA-LH(lweek)/2.68 and top point of TA-LB(lweek)3.50, and texture were lowest in TA-LB(1week) (2.68) and highest in TA-LB(4weeks) (3.45).

조직간 정보시스템의 전략적 선택에 관한 연구

고석용 제주한라대학 1999 論文集 Vol.23 No.-

This paper discusses two critical strategic choices that a firm must makes in developing inter-organizational information systems(IOIS)-what kind(s) of IOIS(s) to develop, and how to develop the IOIS(s). With respect to the kind of IOIS(s), it proposes a typology of three different types of IOlSs: electronic monopolies, electronic dyads, and multilateral IOISs. The nature of IOIS can be better understood by examining two typologies that have been proposed. Malon et al. describe two types of IOIS, based on whether they electronically facilities hierarchies or markets. In electronic hierarchies between two legally separated firms, managerial decisions control the flow of materials through the value added chain. Information technology has radically altered the management of supply chain operations: many business patterner who are adjacent on the supply chain con gain from entering interorganizational information sharing relationships and sharing information that was previously accessible to only one of them. This situation is typical in retailer-supply logistics management relationships. This study finds that there are four primary policies that firms adopt when they exchange information across the supply chain; these are EDI, vendor management inventory(VMI), continuos replenishment(CR), and category management(CM).
