In case of inappropriate stacking position of the container taking in container yard, the working time for the container would be delayed in taking out because of the occurrence of the re-handle and the increase of the crane moving time. We have to take into account a variety of elements like the crane interference, the container group and stacking height in order to determine the optimal stacking position and decide the weight reflecting the importance of these criteria. We propose the dynamic weight adjustment algorithm for the stacking policy criteria employing the online search in this research.

This article examines how consumers in online environments depend on brand in making purchase decisions by product types. Previous research explains that the characteristics of online environments decrease the dependence on brand due to inexpensive search costs and affluent information quantity. But it is likely that in online environment, the dependence on brand will be differentiated by product types. We found that in search product, the availability of information decreased consumer's uncertainty, which, in turn, increased the dependence of brand. However, in experience products, the weakness of multi-sensory increased consumer's uncertainty, which resulted in the increase of the dependence of brand.

Importance of online community has been increased and also online community has been used as an important marketing tool. The purposes of this study are to construct an instrument to evaluate service quality of online community service and have a further discussion of the relationship between service quality dimensions, customer satisfaction, intention to move. According to our findings, among the determinants of service quality, empathy strongly influences both of consumer satisfaction and intention to move. The determinants of service quality which positively influences consumer satisfaction are empathy, tangibles and responsiveness. Empathy and assurance negatively influence intention to move. This means that the service quality of online community affects customer retention. Also, understanding and reflecting customer needs are more important.

An overflow of information leads consumers to be easily distracted and to neglect the information being provided to them. E-tailers have to select types of information sources and provide their consumers with the most appropriate information. This study was done to specifically contribute to the research in proposing strategies of providing information of the Internet merchant to the e-shoppers through the analysis of relationships among the online purchase motives of consumers, the use of information sources, and decision making styles. This research categorizes the use of information sources into information sources concerning online stores and information sources concerning products. The uses of information sources relative to online stores are classified into the neutral, human, and marketer-oriented sources. The uses of information sources concerning the products are classified into the online and offline source. This study provides important suggestions for e-tailers to provide information about stores as well as products to the consumers with adaptable strategies.

온라인상점의 상품추천시스템은 일대일마케팅의 대표적 실현수단으로써의 가치를 인정받고 있다. 대부분의 상품추천시스템은 시시각각 변화하는 소비자의 기호에 따라 상품을 어떻게 추천할 것인가에 대한 문제에 직면해 있다. 본 연구에서는 급변하는 온라인상점 환경에 탄력적으로 대응하기 위하여 데이터마이닝과 다중모형조합기법을 이용한 상품추천시스템 모형을 제안하고자 한다. 제안하는 상품추천시스템은 현재 운영중인 온라인상점 데이터로 프로토타입을 구축하고 실제 소비자에 대한 적용가능성을 검증하였으며, 그 결과 실제 유용할 것으로 확인되었다.

The critical link between consumer-based internet ordering and the delivery of the product to the consumer is a key success factor in online shopping. Market areas of online shopping company implies the range of space where products ordered from online shopping can be physically delivered to customers distributed over space with reasonable shipping cost and lead time through the physical distribution network. The average rate of growth in online shopping is 36% per year in Korea for the last 5 years. But there are no maps available that describe sales/delivery density of online shopping, few researches are focused on the short-term/long-term adaptation to demand increase by online shopping. In this paper (1) Maps of trade area are described indicating the sales/delivery density around the nation. (2) Empirical researches suggested that short-term adaptation to demand increase resulted in price reduction and service in enhancement of service quality in local transportation. But the long-term adaptation on the parts of parcel delivery industry are to be investigated in future researches.

본 논문에서는 온라인 필기체 수식 인식을 위한 순차적인 구조 분석 방법을 제안한다. 제안된 방법은 캐블릿상에서 필기된 수식에 대한 심볼 인식 결과와 각 심볼의 Bounding Box이 좌표를 입력받아서 필기 순서를 기반으로 순차적으로 수식의 구조를 해석한다. 그래프 내의 이웃하는 두 노드 사이의 관계를 결정하기 위해서 심볼의 사용에 관한 표기 정보와 6단계 관계 결정 규칙을 사용하여 노드들 사이에 생성될 수 있는 에지의 수를 최소화하고 BackTracking을 피했다. 제안 방법의 성능을 평가하기 위해 100개의 테스트 샘플에 대해 구조 분석 실험을 수행하였다.

웹 상에서 인터넷을 이용한 전자상거래와 관련된 다양한 서비스가 창출되고 있다. 온라인 쇼핑몰에서 발전된 개념인 온라인 경매시스템은 쇼핑몰과는 달리 물품등록, 입찰 및 낙찰, 물품거래의 과정을 거친다 그러나, 대부분의 경매시스템은 입찰 및 낙찰과정에서 거래 당사자간에 신뢰성 있는 가격을 결정짓지 못하고 있다. 따라서, 본 논문에서는 가격 결정 방식에 따른 인터넷 경매의 종류와 유형을 분석한 후 경매 시스템 사용자들에게 사례 유사도와 웹 마이닝을 이용한 가격 정보를 제시하여 객관적인 기준으로 경매 물품의 가치를 평가할 수 있도록 하고, 표준화된 데이터 표현 방법인 XML을 이용한 인터넷 경매 시스템을 설계하고 프로토타입을 구현하고자 한다.

This study illustrates factors that determine consumer types based on ways in which they alternate between online and offline channels for searching and eventually buying their desired products. This study conducted an online survey targeting 1,040 consumers. As per the study, consumer types fall into five groups: 1) on-on type(online search${\rightarrow}$online buying), 2) off-off type(offline search${\rightarrow}$offline buying), 3) on-off type(online search${\rightarrow}$offline buying), 4) off-on type(offline search${\rightarrow}$online buying), and, 5) on-off-on type(online search${\rightarrow}$ offline search${\rightarrow}$nline buying). The primary factors that determine how the different consumer types switch between online and offline channels are price orientation, convenience orientation,, risk-aversion orientation, and channel familiarity. Although they feel cross-channel shopping can be cumbersome, the findings show that cross-channel consumers would gladly switch channels to buy cheaper and proven products. The findings of this study will be useful for businesses that have both online and offline channels and point out the theoretical aspects of the decision-making process as consumers switch between channels.
