A new association rule mining algorithm, which reflects the strategic importance of associative relationships between items, was developed and presented in this paper. This algorithm exploits the basic framework of Apriori procedures and TSAA(transitive support association Apriori) procedure developed by Hyun and Choi in evaluating non-frequent itemsets. The algorithm considers the strategic importance(weight) of feature variables in the association rule mining process. Sample feature variables of strategic importance include: profitability, marketing value, customer satisfaction, and frequency. A database with 730 transaction data set of a large scale discount store was used to compare and verify the performance of the presented algorithm against the existing Apriori and TSAA algorithms. The result clearly indicated that the new algorithm produced substantially different association itemsets according to the weights assigned to the strategic feature variables.

The purpose of this article is primarily to give prominence to the importance of International Business English education. Although English is one of the most crucial parts in international business transaction it has not been treated as one of academical sciences. As English is a main language when the international business transaction is done International Business English should be studied by scholars who majored in international business area. It is true that there has been no study at all regarding International Business English(in this article, it does not mean General International Business English) so far. Anyone who does and learn the international business should have some opportunities to have a contact towards international business correspondence and other documents before they do in reality. However, in Korea, most English education has been focused on general English and English certificate tests at universities. At universities' level, it is certainly a scholars' task to study International Business English education in order to provide decent education to the students. For doing so, this article examine, focusing only on reading part, how International Business English should be taught and especially, how reading skills should be activated and integrated with other language skills. This objective will be fulfilled by asking, what reading means in International Business English, as well as what role reading plays in International Business English education.

This study examined the effect of waiting in a service queue on the evaluation of service quality focused on its overall process, mediators and moderators The conceptual model of this paper integrates key variables derived from previous studies of consumer waiting behavior. Data obtained from actual customers in service queue at a hospital was used to test the theoretical framework. First, results from the path analysis confirm that negative affect and acceptability of the wait function as mediators in the process that the perceived duration of the wait affects customer's evaluation of overall service quality. Second, the analysis of the data, with the use of moderate regression shows that disconfirmation of wait time expectations, transaction importance, stability of wait time and wait environment work as moderate variables for the relationship between perceived duration of wait and negative affect. For the relationship between perceived wait time and acceptability of the wait, on the other hand, only transaction import ante shows a significant effect as a moderator.

Purpose The purpose of this paper is to observe the relative priorities of importances among the modified versions of Block chain system, being based on AHP decision support model which should be also proposed in this paper. Design/methodology/approach Four versions modified from the beginning of Block chain were divided into Public& Permissionless, Private&Permissionless, Public&Permissioned and Private&Permissioned types. Five criteria for evaluating the four versions whether the version were suitable for Medical information system were introduced from five factors of Technologies Accept Model, which were Security, Availability, Variety, Reliability and Economical efficiency. We designed Decision support model based on AHP which would select the best alternative version suitable for introducing the Block chain technology into the medical information systems. We established the objective of the AHP model into finding the best choice among the four modified versions. First low layer of the model contains the five factors which consisted of Security, Availability, Variety, Reliability and Economical efficiency. Second low layer of the model contains the four modified versions which consisted Public&Permissionless, Private&Permissionless, Public&Permissioned and Private& Permissioned types. The structural questionnaire based on the AHP decision support model was designed and used to survey experts of medical areas. The collected data by the question investigation was analyzed by AHP analysis technique. Findings The importance priority of Security was highest among five factors of Technologies Accept Mode in the first layer. The importance priority of Private&Permissioned type was highest among four modified versions of Block chain technologies in second low layer. The second importance priority was Private&Permissionless type. The strong point of Private&Permissioned type is to be able to protect personal information and have faster processing speeds. The advantage of Private& Permissionless type is to be also able to protect personal information as well as from forging and altering transaction data. We recognized that it should be necessary to develop new Block chain technologies that would enable to have faster processing speeds as well as from forging and altering transaction data.

글로벌 경쟁시대의 물류산업의 경영환경 변화는 고객이 기업을 선택하는 시대가 되어가고 있다. 고객에게 적합한 제품과 서비스의 제공을 통한 경쟁기업과의 차별화 우위에 따라 고객의 선택은 달라지기 때문에, 기업은 지속적으로 고객에게 선택을 받거나 유지하는데 노력하고 있다. 결국 이러한 경쟁구도는 장기적 관계구축의 중요성으로 부각된다고 볼 수 있다. 이에 본 연구에서는 류기업과 화주기업간의 거래관계에 있어 물류기업이 고객만족을 위해 수행하는 거래특성과 관련된 요인들이 성과와 장기거래의 도에 어떠한 영향을 미치는가를 살펴보았다. 첫째, 물류기업 간 거래에서 고객의 만족을 위해 구체적으로 실현해야 할 물류기업의 거래특성요인인 물류서비스, 비용, 물류인프라 및 기업역량요인을 도출하였다. 둘째, 물류기업의 거래특성요인이 기업의 성과에 어떠한 영향을 미치는 가를 분석해보고, 마지막으로 기업의 성과요인이 장기거래의도에 어떠한 영향을 미치는가를 분석해보았다. 실증분석결과 물류기업의 거래특성요인과 성과 간의 관계에는 통계적으로 유의한 결과가 나오지 않았는데, 이는 표본이었던 물류업체의 영세성에 기인한다고 볼 수 있다. 즉, 저가격으로 서비스를 제공할 충분한 역량이 없는 물류기업들의 경우 끊임없는 출혈경쟁을 벌일 수밖에 없으며, 이는 곧 서비스 산업에서의 대표적 특성인 차별화가 어렵다는 단점을 고스란히 안고 있는 동시에, 치열한 가격경쟁을 벌이고 있는 산업의 특성을 반영하고 있다고 볼 수 있다. 한편 기업성과요인과 장기거래의도 간의 관계는 정(+)의 관계가 있는 것으로 나타났다. 즉, 물류기업과의 파트너십과 가시적인 재무적 성과차원이 높으면 높을수록 앞으로도 지속적으로 거래를 유지하고, 점차 거래물량을 늘려나가기도 하며, 오히려 비용이 좀 더 들게된다 하더라도 거래를 지속적으로 거래하려는 의도가 크게 나타난다는 것을 알 수 있었다.

Since American Airlines's mileage program emerged in market, loyalty programs have gained popularity. Many companies have generated many kinds of reward cards in order to induce precious consumers. As a result, reward cards are very important in consumer goods market and become diversified. In spite of its importance, little is known about how these cards influence consumer's perception. The prior research has not focused on reward card types and psychological variables. Accordingly this research intends to investigate psychological variables such as transaction coupling and sunk cost perception. According to the theory of regulatory focus, promotion focus consumers would point to gain-nongain frame work, but prevention focus consumers would point to loss-nonloss frame work. The paper proved the effect of reward card types and regulatory focus on transaction coupling and sunk cost perception. Based on the results from 2(type of card : visible vs invisible) ${\times}$ 2(regulatory focus: promotion vs prevention) between-subjects factorial design experiments, we found that consumer's transaction coupling and sunk cost perception of visible reward card are better recognized than invisible reward card. In addition, the results show that there is a significant interaction effect between the type of reward card and regulatory focus. Specifically promotion focused consumers tend to reveal better perception than prevention focused consumers in use of invisible cards. However, prevention focused consumers tend to show better perception than promotion focused consumers in use of visible cards. These findings will contribute to significant academic development and practically useful help to marketing managers.
