One of the most important things in channel of distribution is the management of intrachannel conflict. In this study, 1 tried to find out the major sources of conflict among distribution channel members of gasolin industry and home electronics industry which have two types of distribution channels - sales branch and agency. I also investigated how the level of conflict influences the business performance of the channel member. The results of the study showed that the imbalance of power, nonfulfillment of roles by manufacturers, nonfulfillment of roles by dealer, divergence in perceptions, intrachannel communication problem have positive relation but role clarity has negative relation with conflict. The results also indicate that the more power supplier exerts upon dealer, the less supplier and dealer practice their roles, and the more communications problem there is, there will be more conflict between channel members. I also analyzed the relationship between conflict and business performance and the result came out as expected: the more conflict there is the less business performance. Some difference was found between sales branch and agency on that aspect. Managerial implications and limitations of the study were also discussed.

PVSS stands for publicly verifiable secret sharing. In PVSS, a dealer shares a secret among multiple share holders. He encrypts the shares using the shareholders' encryption algorithms and publicly proves that the encrypted shares are valid. Most of the existing PVSS schemes do not employ an ElGamal encryption to encrypt the shares. Instead, they usually employ other encryption algorithms like a RSA encryption and Paillier encryption. Those encryption algorithms do not support the shareholders' encryption algorithms to employ the same decryption modulus. As a result, PVSS based on those encryption algorithms must employ additional range proofs to guarantee the validity of the shares obtained by the shareholders. Although the shareholders can employ ElGamal encryptions with the same decryption modulus in PVSS such that the range proof can be avoided, there are only two PVSS schemes based on ElGamal encryption. Moreover, the two schemes have their drawbacks. One of them employs a costly repeating-proof mechanism, which needs to repeat the dealer's proof at least scores of times to achieve satisfactory soundness. The other requires that the dealer must know the discrete logarithm of the secret to share and thus weakens the generality and it cannot be employed in many applications. A new PVSS scheme based on an ElGamal encryption is proposed in this paper. It employs the same decryption modulus for all the shareholders' ElGamal encryption algorithms, so it does not need any range proof. Moreover, it is a general PVSS technique without any special limitation. Finally, an encryption-improving technique is proposed to achieve very high efficiency in the new PVSS scheme. It only needs a number of exponentiations in large cyclic groups that are linear in the number of the shareholders, while all the existing PVSS schemes need at least a number of exponentiations in large cyclic groups that are linear in the square of the number of the shareholders.

Due to a growing demand for the second-hand product, especially for the expensive one, the warranty and maintenance policies for such products have been studied to improve the product reliability of late. In this paper we study a periodic maintenance model for the second-hand product which is purchased by the customer at the age of $x$. When purchased, the dealer provides a warranty of a fixed length during which the product is maintained periodically to reduce the failure rate of the product and thus, to improve the reliability after each maintenance is served. If a failure occurs between two successive maintenances, only minimal repair is conducted. As for the warranty policy, we adopt free non-renewing repair action on each failure, in addition to the periodic maintenance service during the warranty period. Thus, under the given warranty policy, all the maintenance and repair costs incurred during the warranty period are charged to the dealer. For the proposed periodic maintenance scheme, we formulate a cost model to evaluate the expected total cost charged to the dealer during the warranty period and derive an optimal upgrade level of the failure rate at each maintenance to minimize the expected total warranty cost from the perspective of the dealer. We also present numerical results for an optimal upgrade level based on the proposed methods.

본고는 미국의 타이어 업계지 "Modern Tire Dealer"애서 조사한, 미국의 80년도 타이어 업계 및 타이어 시장 전반에 관한 실적분석이다. 특히' 80년도 미국의 경제침체와 자동차산업의 예외없는 타격으로 전미 타이어 업계에는 근래없는 최악의 해로 기록되고 있다. 즉, 승용차용 타이어 시장을 보면 전년비 15% 감소되었으며, 트럭ㆍ버스용 타이어는 무려 21%의 막대한 감소률을 나타내고 있다. 따라서 많은 타이어 공장의 폐쇄가 속출하는 등 실로 심각한 불황의 한해를 겪은 것 같다.<편집자 주>

Salesperson behavior with respect to selling orientation-customer satisfaction(SOCO) is shown to influence customer satisfaction with the salesperson, dealer, product and manufacturer in of new car purchasers. The influence of selling behaviors on product satisfaction has significant implications for manufacturers in their efforts to enhance market acceptance. Strategies to enhance product satisfaction via salesperson behaviors are discussed.

In current public blockchain, any node can see every blocks, so that public blockchain provider transparent property. However, some application requires the confidential information to be stored in the block. Therefore, this paper proposes a multi-layer blockchain that have the public block layer and the private block for confidential information. This paper suggests the requirement for encryption of private block. Also, this paper shows the t-of-n threshold cryptosystem without dealer who is trusted third party. Moreover, the delegated node who has key information can be withdraw the delegated node group or a new delegated node can join in the delegated node group. Therefore, the paper proposes an efficient key information resharing scheme for withdraw and join. Finally proposed scheme satisfies the requirements for encryption and fairness.

In this study, we examined the distribution of dealers and the repair parts management system of a Japanese car manufacturer in the Chinese market in looking at the case of Toyota. We conducted our research by obtaining information from a GAC Toyota dealer about the current distribution of dealers and locations of warehouses throughout China, as well as the status of stocks and the distribution system for repair and maintenance parts. The results of our investigation showed that although GAC Toyota has 437 dealers throughout the country, there is an imbalance in distribution towards the coastal areas, after the population ratios and other measurements are factored in. Therefore, it can be said expansion towards the inland regions, where demand for automobiles has increased in recent years, has been stunted. On the other hand, there is a high correlation between gross GDP by region and the number of stores, and it can be pointed out that the company prioritizes the sale of high-priced vehicles in major coastal areas where the economy is large, rather than selling low-priced vehicles for inland consumers with a relatively small economic scale. The company also has difficulty in securing dealers that can provide sufficient after-sales service. According to the regulations of GAC Toyota, the company require dealers to have at least 1,500 repair and maintenance parts in stock. Also, when exchanging maintenance parts, GAC Toyota's emphasis is on increasing customer satisfaction by giving sufficient explanations for customers and obtaining consent from them. As a result, the company's dealers need financial resources to continue their business from a long-term perspective. However, it can be pointed out that such dealers are limited, and it is difficult to distribute profits among manufacturers and dealers.

본고는 미국의 타이어 전문지인 "Modern Tire Dealer"에서 조사한 '81년도 미국의 타이어산업 및 타이어 시장 전반에 관한 실적분석이다. 즉, 승용차 및 트럭의 신차용 타이어 시장과 교환용 타이어시장의 브랜드 점유율, 출하량, 생산능력, 재생타이어시장 및 전천후타이어의 성장률 등을 조사 분석한 것이다. '81년도 미국타이어 업계의 실적은 80년도의 최저기록을 크게 벗어나지 못한 체, 총출하량으로는 약2,0% 증가에 불과하였다. 이중에서 신차용 타이어는 80년도 수집을 겨우 유지하고 있는 상태인데, 특히 트럭 ㆍ버스용 타이어에서는 오히려 80년도 실적을 하회하고 있는 실절이다. 한편 교환용타이어는 전년 비 약 2.9% 증가하였다.
