In this study, we investigated the effect of offline banking trust on smart banking trust. As influencing factors of smart banking trust, this study compared offline banking trust, smart banking's system quality, and information quality. For the empirical study, 186 questionnaire data were collected from smart banking users and the data were analyzed using Smart-PLS 2.0. As results, it was verified that there is trust transfer in FinTech service, by the significant effect of offline banking trust on smart banking trust. And it was proved that the effect of offline banking trust on smart banking trust is lower than that of smart banking itself. The contribution of this study can be seen in both academic and industrial aspects. First, it is the contribution of the academic aspect. Previous studies on banking were focused on either offline banking or smart banking. But this study, focus on the relationship between offline banking and online banking, proved that offline banking trust affects smart banking trust. Next, it is the industrial contribution. This study showed that offline banking characteristics of traditional commercial banks affect the trust of emerging smart banking service. This means that the emerging FinTech companies are not advantageous in the competition of trust building compared to traditional commercial banks. Unlike traditional commercial banks, the emerging FinTech is innovating the convenience of customers by arming them with new technologies such as mobile Internet, social network, cloud technology, and big data. However, these FinTech strengths alone can not guarantee sufficient trust needed for financial transactions, because banking customers do not change a habit or an inertia that they already have during using traditional banks. Therefore, emerging FinTech companies should strive to create destructive value that reflects the connection with various Internet services and the strength of online interaction such as social services, which have an advantage over customer contacts. And emerging FinTech companies should strive to build service trust, focused on young people with low resistance to new services.

기존의 웹 디자인은 웹이라는 매체의 특성 상 디자인적인 요소가 매우 중요함에도 불구하고 디자인은 위한 구체적인 방법론이 미약하다. 특히, 많은 소비자들을 유인하고 구매를 촉발시켜야 하는 인터넷 쇼핑몰의 경우에는 더욱 더 그럼하에도 불구하고 이를 위한 전략적인 방법론이 부족하다. 즉, 기존 연구들은 제품의 다양성, 서비스, 촉진, 항해량, 편리성, 사용자 인터페이스 등이 중요하다고 하였지만 실제 인터넷 쇼핑몰을 디자인하는 입장에서는 활용하기가 상당히 애매하다. 그 이유는 이들 요인들은 서로 영향관계를 가지고 있어서 사용자 인터페이스가 복잡하면 항해량이 늘어나 편리성이 감소하고, 제품이 늘어나더라도 검색엔진을 사용하면 상대적으로 항해량이 감소하게 되어 편리성이 증가한다. 따라서, 이들 요인을 활용하여 인터넷 쇼핑몰을 구축하려면 요인간의 영향관계를 면밀히 파악하고 이 영향요인이 소비자의 구매행동에 어떠한 영향을 주는지가 충분히 검토되어야 한다.이에 본 연구에서는 퍼지인식도를 이용하여 인터넷 쇼핑몰 상에서 소비자의 구매행동에 영향을 주는 요인을 추출하고 이들 요인간의 인과관계를 도출하여 보다 구체적이고 전략적으로 인터넷 쇼핑몰을 디자인할 수 있는 방법으로 web-Cogmulator를 제시한다. Web-Cogmulator는 소비자의 쇼핑몰에 대한 암묵지식 형태의 구매행동을 형태지식화하여 지식베이스 형태로 가지고 있기 때문에 인터넷 쇼핑몰의 다양한 요인의 변화에 따른 소비자의 구매행동을 추론 시뮬레이션하는 것이 가능하다. 이에 본 연구에서는 기본적인 인터넷 쇼핑몰 시나리오를 바탕으로 추론 시뮬레이션을 실시하여 Web-Cogmulator의 유용성을 검증하였다.를, 지지도(support), 신뢰도(confidence), 리프트(lift), 컨빅션(conviction)등의 관계를 통해 다양한 방법으로 모색해본다. 이 연구에서 제안하는 이러한 개념계층상의 흥미로운 부분의 탐색은, 전자 상거래에서의 CRM(Customer Relationship Management)나 틈새시장(niche market) 마케팅 등에 적용가능하리라 여겨진다.선의 효과가 나타났다. 표본기업들을 훈련과 시험용으로 구분하여 분석한 결과는 전체적으로 재무/비재무적 지표를 고려한 인공신경망기법의 예측적중률이 높은 것으로 나타났다. 즉, 로지스틱회귀 분석의 재무적 지표모형은 훈련, 시험용이 84.45%, 85.10%인 반면, 재무/비재무적 지표모형은 84.45%, 85.08%로서 거의 동일한 예측적중률을 가졌으나 인공신경망기법 분석에서는 재무적 지표모형이 92.23%, 85.10%인 반면, 재무/비재무적 지표모형에서는 91.12%, 88.06%로서 향상된 예측적중률을 나타내었다.ting LMS according to increasing the step-size parameter $\mu$ in the experimentally computed. learning curve.

오늘날 인터넷을 통한 정보검색이 일상화되면서 생활상식에서부터 기존에 서적이나 논문 등을 통해서만 알 수 있었던 전문지식까지도 손쉽게 찾을 수 있게 되었다. 즉, 현대생활에 있어서 검색엔진은 원하는 정보를 빠르고 정확하게 찾을 수 있게 해준다는 점에서 매우 중요하다고 할 수 있다. 하지만 이러한 중요성에도 불구하고 검색엔진 기술적인 연구이외에는 서비스 품질이나 고객만족에 대한 연구는 활발하게 이루어지지 않고 있다. 따라서, 본 연구에서는 검색엔진 서비스에 있어서 서비스 품질과 서비스가치, 고객만족, 충성의도의 관계를 연구모형으로 설정하고 이들간의 관계를 분석하였다. 그 결과 서비스품질의 정확성, 정보함유량, 사이트 이미지, 편리성이 서비스가치에 정(+)의 영향을 미치는 것으로 나타났으며, 그중에서 정확성, 사이트 이미지, 신뢰성은 고객만족에도 정(+)의 영향을 미치는 것으로 나타났다. 또한 서비스가치가 높을수록 고객만족은 상당히 높아지는 것으로 나타났으며 고객만족이 충성의도에 많은 영향을 주는 것으로 나타났다. 본 연구의 결론은 검색엔진 서비스 기업이 경쟁우위를 유지하기 위해서는 서비스가치의 구현을 통한 지속적인 고객만족을 달성해야 하며, 이를 위해 정확성, 정보함유량, 편리성, 사이트 이미지에 중점을 둔 고품질 서비스 전략의 필요성을 시사하고 있다.

Internet information search engines using web robots visit servers conneted to the Internet periodically or non-periodically. They extract and classify data collected according to their own method and construct their database, which are the basis of web information search engines. There procedure are repeated very frequently on the Web. Many search engine sites operate this processing strategically to become popular interneet portal sites which provede users ways how to information on the web. Web search engine contacts to thousands of thousands web servers and maintains its existed databases and navigates to get data about newly connected web servers. But these jobs are decided and conducted by search engines. They run web robots to collect data from web servers without knowledge on the states of web servers. Each search engine issues lots of requests and receives responses from web servers. This is one cause to increase internet traffic on the web. If each web server notify web robots about summary on its public documents and then each web robot runs collecting operations using this summary to the corresponding documents on the web servers, the unnecessary internet traffic is eliminated and also the accuracy of data on search engines will become higher. And the processing overhead concerned with web related jobs on web servers and search engines will become lower. In this paper, a monitoring system on the web server is designed and implemented, which monitors states of documents on the web server and summarizes changes of modified documents and sends the summary information to web robots which want to get documents from the web server. And an efficient web robot on the web search engine is also designed and implemented, which uses the notified summary and gets corresponding documents from the web servers and extracts index and updates its databases.

The main purpose of this study is to conceptualize and investigate the relationship between customer satisfaction and the linking variables of customer loyalty in internet shopping mall including general merchandise and specialized online mall. To achieve this objective, the study tries to validate the structural equation model and causal relationships among the model's elements involving customer satisfaction, customer trust, customer attitude, relationship involvement, and customer loyalty. The same research model was used in analysing general merchandise and specialized internet shopping mall to reveal and compare the casual path constructs. Empirical findings are as follows: First, all the hypothesis concerned with internet merchandise shopping mall were accepted but the direct effects between satisfaction $\Rightarrow$ loyalty and satisfaction $\Rightarrow$ attitude rejected in case of specialized internet shopping mall. Second, I found out that there were direct or indirect relationships between the mediating variables(satisfaction, attitude, involvement) and site trust and customer loyalty irrespective of internet shopping site patterns. In Particular, the direct effects of on customer loyalty showed the difference each other, but the indirect effects through satisfaction, attitude, or relationship involvement were all accepted. This means that the proper management concerned with indirect path is probably more important for the success of all kinds of internet shopping mall. The implications of this research may be summarized as follows. First, click and mortar companies should clearly understand and articulate the key requirements of shopping mall trust and satisfaction. Second, online companies are encouraged to establish linkage including trust, positive attitude, relationship involvement in order to foster customer loyalty. Third, companies are not only required to differentiate the internet marketing strategy adapting to the patterns of internet shopping mall but also to customize the interaction strategy in the formation process of customer loyalty.
