Consumers currently show cross-channel shopping behavior between the Internet and store-based retail types when searching information and purchasing sensory products such as fashion items to reduce risks. As consumers compare both types of stores before making a purchase decision, the Internet retail type and store-based retail type started conflicting/competing each other as the combined retail evolution theory proposed(Kim & Kincade, 2006). The purpose of this study is to examine consumers' cross-channel shopping behavior between the Internet and store-based retail types and their importance and satisfaction with information provided by the Internet retail stores. This study employs a quantitative research method using a survey. Demographics, types of stores used for purchase, satisfaction with the type of stores, Internet shopping behavior, importance and satisfaction with product information in the Internet retail stores were asked. MANOVA and descriptive statistics were used to test hypotheses. The result shows that a majority of participants(36.2%) shows cross-channel shopping behavior between the two retail types. Also, most participants(72.4%) decide on their purchase and are satisfied only after cross-channel shopping between the two retail types. Participants were grouped based on their information search and purchase behavior. Significant differences among the groups were found in importance and satisfaction with product information provided by the Internet stores. In measuring participants' satisfaction, a majority of participants(42.1%) showed satisfaction with their purchase at store-based retail stores after information search via the internet, followed by the satisfaction with the purchase at the internet retail stores after information search at store-based retail stores(30.3%). Fifty one point nine percent of participants search information via the internet(vs.48% at store-based retail stores), and they especially look for fiber contents and design details with pictures(37.4%). The satisfaction with price information provided by the Internet retail stores is the highest (m=3.70 out of 5.0) among fashion product information followed by design information(m=3.48). On the other hand, size information, refund/exchange and fiber content information received low satisfaction scores(m=2.81, 2.71, 2.57 in turn). This research suggests the Internet retail stores should provide more variety of information in detail using technology and improving customer services. This study could provide the Internet retail stores a guideline to establish a satisfactory information delivery system.

This study was conducted to examine the level of exposure, credibility and usefulness of the food tourism information channel perceived by foreign tourists visiting Korea. A total of 230 survey questionnaires were distributed to Japanese and Chinese tourists, who account for the highest percentage of tourists visiting Korea. The results showed that tourists were segmented into three groups based on their participation in food tourism activities: culinary tourists, experiential tourists and general tourists. Japanese tourists participated more actively in food tourism activities than Chinese tourists. The information channel used most frequently by tourists was 'word-of-mouth,' while the least used channel was 'e-mail catalog contains food tourism information.' Culinary tourist most actively used online and offline channels to search for food tourism information. Perceived credibility and usefulness of the food tourism information channel differed by nationality and food tourist segments. This study provides meaningful implications regarding food tourism promotion strategies.

본 연구는 소비자의 구매과정을 정보탐색 및 구매결정 단계로 나누어 각각의 단계에서 소비자가 온라인 또는 오프라인 채널을 선택하는 행동에 영향을 주는 요인을 분석하였으며 어떤 요인이 채널 전환(온라인 탐색$\rightarrow$오프라인 구매, 오프라인 탐색$\rightarrow$온라인 구매)을 가져오는지 검증하였다. 영향 요인으로는 소비자 개인 특성, 제품 특성, 구매 상황과 관련된 10개 변수를 고려하였으며, 순차적 로짓(sequential legit) 기법을 사용하여 실증 분석한 결과를 요약하면 다음과 같다. 정보탐색 단계에서는 소비자의 채널에 대한 지식이 채널 선택에 영향을 미쳤으며 쇼핑에서 재미를 추구하거나 제품에 대한 관여도가 높은 경우 오프라인 채널을 선택할 가능성이 높게 나타났다. 반면에 온라인으로 쇼핑한 경험이 많은 소비자들은 온라인에서 정보를 탐색하는 경향이 높았다. 구매 단계의 검증결과는 탐색 채널에 따라 다르게 나타났다. 소비자가 온라인에서 정보를 탐색한 경우, 온라인 쇼핑경험이 많거나 가격추구의 쇼핑 가치를 크게 느끼거나 시간적 여유가 없는 소비자일수록 온라인에서 구매하는 경향이 높았던 반면에, 필요한 정보의 양이 많거나 제품에 대한 관여도와 인지된 위험이 높은 소비자는 구매 단계에서 오프라인 채널로 전환하였다. 한편 소비자가 오프라인에서 정보를 탐색한 경우, 쇼핑에서 편의나 재미를 추구하는 소비자와 시간적 여유가 없는 소비자일수록 오프라인에서 구매할 가능성이 높았고, 온라인 쇼핑경험이 많은 소비자는 구매 채널을 온라인으로 전환하는 경향이 높았다. 본 연구의 분석결과는 정보탐색 및 구매 단계에서 채널 선택에 영향을 주는 요인이 서로 다름을 보여주었으며 두 개의 채널을 모두 제공하는 유통 업자에게 매우 유용한 실무적 시사점을 제공한다.

This paper is concerned with the use of a selforganizing map (SOM) to estimate the desired channel states of an unknown digital communication channel for blind equalization. The modification of SOM is accomplished by using the Bayesian likelihood fitness function and the relation between the desired channel states and channel output states. At the end of each clustering epoch, a set of estimated clusters for an unknown channel is chosen as a set of pre-defined desired channel states, and used to extract the channel output states. Next, all of the possible desired channel states are constructed by considering the combinations of extracted channel output states, and a set of the desired states characterized by the maximal value of the Bayesian fitness is subsequently selected for the next SOM clustering epoch. This modification of SOM makes it possible to search the optimal desired channel states of an unknown channel. In simulations, binary signals are generated at random with Gaussian noise, and both linear and nonlinear channels are evaluated. The performance of the proposed method is compared with those of the "conventional" SOM and an existing hybrid genetic algorithm. Relatively high accuracy and fast search speed have been achieved by using the proposed method.

The purpose of this study was to determine the satisfaction, trust and word-of-mouth intention of online information according to the type of information search by female cosmetics consumers in their 20's to 40's. For this study, online and offline surveys were conducted by 307 people. Factor, correlation, and multiple regression analysis were used to analyze the data. The main results are summarized as follows. First, the cosmetic consumer's information search types were identified as active, playful, and economic information search types. Second, the results of examinations on the effect of consumer information search types on satisfaction, reliability, and word-of-mouth intention of the online information searches showed that the active information search type had a positive effect on satisfaction, reliability, and word-of-mouth intention. The economic information search type had a positive effect on satisfaction. The active information search type was confirmed to have high satisfaction, reliability, and word-of-mouth intention for the provided information and thus, the acceptance of the provided information was high. The playful information search type was divided into continuous, habitual, and independent information search and a tendency to assign a low value to consumer information was confirmed. The economic information search type showed high satisfaction with the information obtained by searching, but also a passive attitude toward trust or word-of-mouth intention and was categorized as a passive search type. Online information search is a communication channel with a great influence that can provide various benefits to cosmetic consumers.

The purpose of this study was to investigate on what kinds of consumer confusion exist and how much confusion consumers experience during their information search process. In-depth interviews and a questionnaire survey with college students were conducted to figure out the type and the level of consumer confusion. Results showed that college students were somewhat confused when they chose information channel and when they understood and used the chosen information. It was found that confusion was due to partly because of too many information and partly because of the lack of consumer searching skill.

Information is an essential factor leading the rapid progress which is one of the distinguished characteristics in modem society. As more information is required and as more is supplied by individuals, governmental units, businesses, and educational institutions, the greater will be the requirement for efficient methods of communication. One possibility for improving the information dissemination process is to use computers. The capabilities of such machine are beginning to be used in the process of Information storage, retrieval and dissemination. An important problems, that must be carefully examined is whether one technique for information retrieval is better for worse than another. This paper examines problem of how to evaluate an information retrieval system. One specific approach is a cost accounting model for use in studying how to minimize the cost of operating a mechanized retrieval system. Through the use of cost analysis, the model provides a method for comparative evaluation between systems. The general cost accounting model of the literature retrieval system being designed by this study are given below. 1. The total cost accounting model of the literature retrieval system. The total cost of the literature retrieval system = (the cost per unit of user time X the amount of user time) + ( the cost per unit of system time X the amount of system time) 2. System cost accounting model system cost = (the pre-search system cost per unit of time X time) + (the search system cost per unit of time X time) + (the post search system cost per unit of time X time) 1) Pre-search system cost per unit of time = cost of channel per unit time + cost of central processing unit per unit time + cost of storage per unit time 2) Search system cost per unit of time = comparison cost + document representation cost. 3) Post-search system cost per unit of time. = cost of channel per unit time + cost of central processing unit per unit time + cost of storage per unit time 3. User cost accounting model Total user cost = [pre-search user cost per unit of time X (time + additional time) ] + [search user cost per unit of time X (time + additional time) ] + [post-search user cost per unit of time X (time + additional time) ].

In this paper, a frequency domain Expectation-Maximization (EM)-based channel estimation algorithm for Space Time Block Coded-Orthogonal Frequency Division Multiplexing (STBC-OFDM) systems is investigated to support higher data rate applications in wireless communications. The computational complexity of the frequency domain EM-based channel estimation is increased when higher order constellations are used because of the ascending size of the search set space. Thus, a search set reduction algorithm is proposed to decrease the complexity without sacrificing the system performance. The performance results of the proposed algorithm is obtained in terms of Bit Error Rate (BER) and Mean Square Error (MSE) for 16QAM and 64QAM modulation schemes.

본 논문에서는 파일롯 채널(pilot channel)이 존재하는 직접확산 코드분할 다중접속 방식(DS-CDMA)에서 PN 코드의 초기 동기획득 성능을 개선하기 위해 연판정 기법을 사용하는 방법을 제안한다. 본 논문에서 제안하는 연판정 기법을 하이브리드 동기획득 알고리듬에 적용하고, 평균 동기획득 시간 측면에서 분석한다. 분석을 위해, 제안된 방식의 수학적 모델을 제시하고, IMT-2000 채널모델에서 시뮬레이션을 수행한다. 수식적인 분석 결과, 제안된 방식이 한 쌍의 임계치를 사용하는 기존 방식에 비해 평균 동기획득 시간에서 약 0.2초 내지 0.4초 정도의 성능향상을 가져오는 것을 보여준다. 이것은 연판정 기법이 기존의 경판정 기법의 사용으로 인한 성능열화를 보상함으로써 생기는 이득이라고 볼 수 있다.
