In recent retail environments, multichannel customer management increasingly has been considered a key element of successful CRM. Although customer's multichannel usage is believed to be potential cause of customer loyalty, the theoretical explanation about this causal relationship still remains unexamined and unanswered. In this paper, the authors present a systematic framework to test the postulated "multichannel usage-shopping experience-customer satisfaction" chain. To this end, we examine that the two core components of shopping experience(convenience and enjoyment) is a mediator of the direct causality of multichannel usage(based on both information search and product purchase stage) on customer satisfaction. Moreover, the authors examine that two types of customer-firm relationship characteristics(relationship age and purchase frequency) is a moderator of the multichannel usage-shopping experience relationship. Using integrating data with survey and customer database of multichannel retail company, the authors empirically test and substantiate shopping experience's mediating role in the multichannel usage-customer satisfaction relationship and customer-firm relationship characteristics' moderating role in the multichannel usage-customer experience relationship. These results suggest that multichannel retailers should deliver favorable shopping experience for building customer satisfaction and differentiate shopping experience according to customer-firm relationship characteristics.

평면변형조건에서 성형한계를 빠르고 정확하게 측정할 수 있는 방법을 개발하는 것도 중요하다. 평면변형조건에서의 성형한계를 구하는 데에는 펀치 스트레칭이 주로 이용되지만 그 외에도 여러 가지 방법들이 시도되고 있다. 평면변형조건에서 펀치스트레칭 시험을 행하여 파단이 일 어날 때까지의 펀치 행정거리를 한계 돔 높이(limiting dome height)라 하여 선진 제국에서는 박판금속의 성형성에 대한 품질관리 수단으로서 이용하고 있다. 우리나라의 박판금속의 성형 업계에서도 새로운 공정의 개발에 있어서 성형한계도와 변형측정법을 이용하므로서 시행착오를 줄이고, 한계돔 높이에 의한 품질관리기법을 이용하므로서 불량율저감 및 생산성 향상을 기할 필요가 있다 하겠다. 각종 재료에 대하여 측정한 성형한계에 관한 자료는 그 대표적인 값(예를 들면, 평면변형에서의 성형한계 값)으로서 컴퓨터에 저장하여두면 성형성에 대한 CAE에 의한 분석시에 편리하게 이용될 수 있다.

The study shows a method called a square-inventory method, which is a better and faster method than scanline survey and window method for an analysis of slope stability. The study area is located in the Changri area, Boeun-Gun, Chungbuk, and consists of many formations of the Okcheon Supergroup. Various types of failure are observed from the phyllite including the rocks in the study area. The physical properties of meta-sedimentary rocks are that minerals of the rocks are composed of microcrystalline quartz and sericite, which are arranged parallel to bedding (or schistosity) and crenulation cleavage. Therefore, such properties affect geotechnical ones of the rock. The slope stability are analyzed by selecting 3 areas, each of which are divided into 2 or 3 slopes of $1m{\times}1m$ area that represent each of 3 investigation sites. The possibility of wedge and toppling failure is very high in all 3 areas by using square-inventory method. Although possibility of plane failure is weak in the investigation site 2, the plane failures are frequently found from the slope of site 2. The bedding (or schistosity) plane and cleavage, another types of discontinuity coexist in meta-sedimentary rocks uulike igneous rocks, and therefore are important factors to be considered together with joint structures in th ε analysis of slope stability.

The purpose of this study is to investigate the determinants of consumer's repurchase intention in the foreign direct sales shopping malls, focusing on the Japanese customers. Research model of the study is composed of seven independent variables (price competitiveness, product diversity, reputation, country-of-origin image, ease of use, delivery service, after service), a mediating variable (trust) and a dependent variable (repurchase intention). The results of this study show that trust is an important factor affecting the repurchase intention of customers. Customers' trust is affected by the reputation, country-of-origin image, ease of use, delivery service, after service. However, price competitiveness and product diversity, which are hypothesized to affect the trust, are not statistically significant. This study will provide a basis for future research on the foreign direct sales area. In addition, it will provide practical information useful in launching and/or operating the foreign direct sales malls.

t Global logistics companies are developing and introducing logistics systems to provide competitive logistics services. Especially as IT develops and mobile functions become more convenient, the Mobile TMS(Transportation Management System) is being introduced as a more convenient system for delivery workers and office managers. However, the success of such a system depends on the system developer who understand the site accurately and office managers and couriers who are using it in the field. The purpose of this paper is to understand which characteristics influence in exploiting new systems focusing on the attitudes of users who use the system daily, and we analyze it through the TAM(Technology Acceptance Model). According to the analysis result, when smart phone has become popular, users have concluded that usefulness is more significant than ease in acceptance of the systems. As a result, we draw suggestions that the focus should be on usefulness rather than ease of system at the stage of system developed.

In the near future, it is expected that the use of autonomous mobility-on-demand services will increase. Considering its complicated service components, including vehicle convenience, driving and matching speed, and platform convenience, the priorities of them will need to be determined for a successful establishment. In this context, this study examined the importance rank of each service component through an online survey of potential users of autonomous mobility-on-demand services. As a result of the AHP (Analytic Hierarchy Process) with respect to the upper-level components, driving and matching speed component is selected as most important, followed by platform convenience and vehicle convenience. Mean rank analysis with respect to lower-level components showed that the in-vehicle congestion level of vehicle convenience, waiting time of driving and matching speed, and pre-booking availability of platform convenience each ranked first. Additional analysis regarding each group was conducted to establish a group-specific strategy. As a result, it would be better to focus on a vehicle than a mobile platform when designing services for the region with a high proportion of the older. Moreover, it is recommended to speed up the driving and matching speeds more than the current public transport, alleviate in-vehicle congestion, and enable the users to book the schedule in advance.

The purpose of this study is to define determinants of tourists' behavior focused on tourism omni-channel and to verify the relationship between tourism information search motivation, tourism omni-channel satisfaction, tourism experience and perceived risk. We presented the hypotheses including ease of use, trust and satisfaction and also analyzed the moderator effects of tourism experience and perceived risk(financial risk, psychological risk) variables. For an accuracy of expected results, we focused on survey with 298 respondents. Based upon prior studies, it is meaningful that this study verified 1) the positive relationship between tourism information search motivation and tourism omni-channel satisfaction and 2) the significant moderating effect of financial risk on the relationship between tourism information search motivation and tourism omni-channel satisfaction.
