The purpose of this study was to develop service quality dimensions for fashion retail stores and to identify significant service quality dimensions influencing customers satisfaction for each fashion retail store. 687 young adults completed written questionnaires consisting of items related to service quality. For analysis of data, confirmatory factor analysis, one-way ANOVA, scheffe test, and stepwise regression analysis were applied. The results were as follows: 1. The service quality dimensions of fashion retail stores were tangibles, reliability, responsiveness, assurance, empathy, fashionability and variety, price, convenience, merchandise quality and credit card usability. Among those 10 main dimensions of service quality were grouped as experience attributes and search attributes. 2. In examination of the highest valuable service quality dimension based on the types of stores, imported fashion stores were evaluated the highest in terms of all factors except price, tangibles and credit card usability. 3. To predict consumer satisfaction, service quality dimensions such as reliability, responsiveness, assurance, empathy, fashionability/variety, price, convenience, merchandise quality and credit card usability should be considered.

The mobile visual search service uses a query image to acquire linkage information through pre-constructed DB search. From the standpoint of this purpose, it would be more useful if you could perform a search on a web-based keyword search system instead of a pre-built DB search. In this paper, we propose a representative query extraction algorithm to be used as a keyword on a web-based search system. To do this, we use image classification labels generated by the CNN (Convolutional Neural Network) algorithm based on Deep Learning, which has a remarkable performance in image recognition. In the query extraction algorithm, dictionary meaningful words are extracted using Wikipedia, and hierarchical categories are constructed using WordNet. The performance of the proposed algorithm is evaluated by measuring the system response time.

UDDI (Universal Discovery Description and Integration) Registry is used for Web Services registration and search. UDDI offers the search result to the keyword-based query. UDDI supports WSDL registration but it does not supports WSDL search. So it is required that contents based search and ranking using name and description in UDDI registration information and WSDL. This paper proposes a retrieval engine considering contents of services registered in the UDDI and WSDL. It uses Vector Space Model for similarity comparison between contents of those. UDDI registry information hierarchy and WSDL hierarchy are considered during searching process. This engine suppports two discovery methods. One is Keyword-based search and the other is template-based search supporting ranking for user's query. Template-based search offers how service interfaces correspond to the query for WSDL documents. Proposed retrieval engine can offer search result more accurately than one which UDDI offers and it can retrieve WSDL which is registered in UDDI in detail.

The purpose of this study was to make a comparative analysis of dental question and answer in portal sites. To achieve this, 4,212 questions were used for final analysis after connecting to Naver, Daum and Nate, which take first, second and third place in rank information of all sites at Rankey.com, to search dental information by keyword from January to late March. The results are as follows. Naver was the highest as a portal of Internet search engines. Questions on the use of dental clinics, the quality of dental services and the offer of dental services by types of dental clinics were very important. Dental clinics had to give dental patients customized services and information to please them through dental services and dental information services on the Internet, and questions and answers on this were increasing very explosively. Consequently, Dental clinics will have to give Internet users and health- and disease-related data searchers distinctive professional services by inquiring into factors affecting portal search and factors affecting health- and disease-related search, respectively.

Purpose - A product bundling is a marketing approach where multiple products or components are packaged together into one bundle solution. This paper aims to introduce an optimal bundle search problem (hereinafter called "OBSP") which may be embedded with online recommendation system to provide an optimized service considering pairwise discount and delivery cost. Research design, data, and methodology - Online retailers have their own discount policy and it is time consuming for online shoppers to find an optimal bundle. Unlike an online system recommending one item for each search, the OBSP considers multiple items for each search. We propose a mathematical formulation with numerical example for the OBSP and analyzed the complexity of the problem. Results - We provide two results from the complexity analysis. In general case, the OBSP belongs to strongly NP-Hard which means the difficulty of the problem while the special case of OBSP can be solved within polynomial time by transforming the OBSP into the minimum weighted perfect matching problem. Conclusions - In this paper, we propose the OBSP to provide a customized service considering bundling price and delivery cost. The results of research will be embedded with an online recommendation system to help customers for easy and smart online shopping.

With the recent increase in the types of services provided by Internet companies, collection of various types of data has become a necessity. Data collectors corresponding to web services profit by collecting users' data indiscriminately and providing it to the associated services. However, the data provider remains unaware of the manner in which the data are collected and used. Furthermore, the data collector of a web service consumes web resources by generating a large amount of web traffic. This traffic can damage servers by causing service outages. In this study, we propose a website search engine that employs a system that controls user information using blockchains and builds its database based on the recorded information. The system is divided into three parts: a collection section that uses proxy, a management section that uses blockchains, and a search engine that uses a built-in database. This structure allows data sovereigns to manage their data more transparently. Search engines that use blockchains do not use internet bots, and instead use the data generated by user behavior. This avoids generation of traffic from internet bots and can, thereby, contribute to creating a better web ecosystem.

The primary purpose of this study is to examine consumers'probing actions to see what information sources consumers search for medical information when there are diverse medical service information channels, and classify consumers by information source. Its secondary purpose is to understand trust of information and attitude toward information by consumer type, value of medical service, satisfaction with medical service, and word-of-mouth intention. This study will concretely identify information utilization patterns of medical consumers, and explain the unique characteristics and behavior of segmented types of medical consumers. The significance of this study lies in the search for ways to establish information channels trusted by consumers for building an efficient medical service market in the future. The results of this study show that consumers were classified by the latent class analysis(LCA) into 5 types: low-level information seekers, word-of-mouth information seekers, mass media information seekers, digital information seekers and diverse information seekers. The reliability of information sources by type of medical consumer was statistically significant, and in the analysis of differences in consumer attitude, there was a statistically significant difference in cognitive responses. The value of medical service was statistically significant in health recovery and medical service word-of-mouth intention.

Food environment has been going through significant changes with the introduction of Information and Communication Technology (ICT). This study was conducted to investigate the current development status of ICT related to food delivery service by analyzing the relevant registered patents according to consumer buying process. Patents registered between 2002 and 2016 were searched with 'food' and 'delivery' as main keywords through Korea Intellectual Property Rights Information Service (www.kipris.or.kr). The search resulted in 624 patents among which 219 patents were related to food delivery service; 108 patents based on ICT were selected and analyzed. The patents were examined by applicant and year. The patents were classified into the six steps of consumer buying process: 'need recognition', 'information search', 'evaluation', 'choice', 'purchase', and 'postpurchase evaluation'. Patents belonging to more than one step were coded to all the corresponding steps. The patents were registered mainly by domestic companies (50.9%) and individuals (35.2%), having shown dramatic increase of registration since 2012. Over 2/3 (67.6%) of the patents were related to the 'purchase' step. About 32% were associated with the 'information search' step. Approximately 18% of the patents were relevant to the 'evaluation' and 'choice' steps, respectively. The numbers of patents related to the 'postpurchase evaluation (13.9%)' and 'need recognition (12.0%)' steps were relatively low. The current ICTs related to food delivery service in Korea were largely associated with service providers' profit generation rather than consumers' benefit. There is still much room for technology development that could contribute to increasing consumers' benefit.
