This study was conducted to analyze the characteristics of the artificial intelligence chatbot service of the library and compare the usability of the chatbot service applied to the library, and to propose a plan to improve the usability of the artificial intelligence chatbot service in the library. In order to achieve this research purpose, usability comparison factors were extracted through previous studies on the usability evaluation of artificial intelligence chatbot services, and based on case studies, artificial intelligence chatbot services applied to libraries were classified into their own website-based and SNS-based chatbot services according to the platform. Experiments, questionnaires, and interviews were conducted to evaluate the usability of website-based and SNS-based chatbot services applied to the library. Based on the results of the usability evaluation, implications and improvement plans for the artificial intelligence chatbot service of the library were derived.

This study intends to review the quality factors of library service for the disabled using user-centered approach. For the empirical review of quality factors, Nine quality factors were drawn after analyzing the current library service quality factors and the standards of library service for the disabled. Using these factors, The survey for identifying importance of factors and the qualitative evaluation of service cases were performed in this study. As a result of this survey, the most critical but relatively weak quality factors were facility, collection and staff factors. And the qualitative evaluation results of service cases indicated that the reading culture program and the information service factors were critical.

In this study, the service concept was explained, which could be applied to the development process of new service in service design specially. The service concept has the important role in decision making in the service planning stage as to the new strategic service development or service remodelling. This service concept is very useful for customized operational planning or service recovery through the combination of various service element, and for reviewing the possibility of service's success as of customer's acceptance related to business model throughout the service concept test. Finally, in this study, some models are suggested that the service development model including the service concept, also the test model about service concept in the process of service development.

This paper presents an evaluation framework for prototyping multimedia streaming services including audio and video in a distributed and/or decentralized storage that can evaluate service quality and performance under various network conditions. The evaluation framework focuses on important indicators which measure and improve service quality by applying decentralized storage to multimedia streaming services that can mimic the scalability of the existing server-client software architecture and the issue of a single point of failure. The integrated framework not only measures performance indicators for evaluating the quality and performance of multimedia streaming on open source based multimedia content streaming services, but also adjusts network quality using network virtualization technology for comprehensive evaluations. The experimental results show that the integrated framework has low overhead in building and operating a decentralized storage with multimedia streaming services on a single host computer which validates the scalability of the developed framework.

The quality of service on urban roadways have been evaluated mainly based on such quantitative measures as travel speed and delay. However, in addition to the quantitative aspects, drivers traveling on urban roadways are subject to be influenced by qualitative measures such as aesthetic aspects of the roadway and other drivers' violation of traffic laws. Based on this notion, this study attempts to identify roadway service quality indices, considering both qualitative and quantitative aspects and evaluate the quality of service using the modified Importance-Performance Analysis (IPA), a technique often applied in the field of marketing. The modified IPA is proposed in this study as a way to evaluate the service quality, reflecting the relative performance between study areas and performance indices. A case study is implemented over the Gangnam and Gangbuk areas in Seoul, resulting in identifying the items needed to be improved for each study area.

Currently, suggesting directions for strengthening publicity of social services is thinking in the direction of each person's advantage from the stakeholder's perspective. The position of the service provider and the position of the user shows different opinions on the definition and evaluation of publicity of the city or province as the management entity. Therefore, this study combines opinions on publicity focusing on community service, derives consensus on the definition and evaluation of publicity, and evaluates different indicators or factors that cannot be quantified at the same time. The goal is to solve the problem of publicity by applying the Analytic Hierarchy Process(AHP) as a possible technique. In addition, in order to achieve the research objectives according to the designed frame, an empirical study was conducted by conducting a pairwise comparison questionnaire for experts and users. Through the AHP evaluation model" developed in this study, as a result of measuring the relative satisfaction of major factors, service utilization rate (0.470), facility management (0.210), and other project implementations (0.073) appeared in order. Here, the service utilization rate was evaluated as the most important.

A shipbroking is maritime service business, which is consist of market of freight, shipbuilding, sales & purchase and demolition for intermediation between customer and supplier. In this way, a shipbroking business has strong relationship with shipping industry and is also knowledge service business for creation additional value based on shipping, shipbuilding, financial and law etc. However, the research on the evaluation items and a method for shipbroking company were not carried out in previous research. In this paper, We defined evaluation items with three high level, six middle level and sixteen low level for evaluation of shipbroking service by expert's brainstorming and AHP(analytic hierarchy process) method. And also carried out survey to employees of shipbroking company as supplier and shipping company as customer. As a result of survey, result of service in high level, convenient of middle level and credibility of low level are evaluated highly, and also business credit rating, profit of customer, achievement of customer's object are considered to more important than others items. In case of comparison between group, a method of contact with client, problem-solving ability, good relationship with clients of international and domestic evaluated importantly in common.
