Criteria for evaluating digital libraries have been suggested in prior studies, but limited research has been done to understand users' perceptions of evaluation criteria. This study investigates users' opinions of the importance of digital library evaluation criteria. Thirty user participants, including 10 faculty members and 20 students, were recruited from five universities across the United States. They were asked to rate the importance of evaluation criteria in eight dimensions (e.g. collections, information organization, context, etc.). The results demonstrate that users care about evaluation criteria related to the use and quality of collection and services rather than the operation of digital libraries. The findings of this study are relevant to the development of user-centered digital libraries and associated evaluation frameworks through the incorporation of unique users' needs and preferences.

The evaluation of public transit service quality is more complicated than evaluating other aspects of transportation service. Although various measures of effectiveness [MOEs] for transit service have been studied and applied, a more comprehensive and accurate MOE is still required. In the past, either data from user surveys or the experience of bus agency administrators and/or engineers used to measure the quality of service. However, recently, with reliable and accurate real time data from BMS(Bus Management System) and BIS(Bus Information System), more reliable and accurate MOEs are available. This study develops a service evaluation model from users' perspectives, which is based on user' cost models that consider passenger access time, riding time, waiting time, and discomfort due to in-vehicle overcrowding, violation of traffic laws, and accident rate. For validating proposed model, data from the BMS and transit-fare cards (T-Money Card) for Seoul's No. 472 main bus line were used. Models developed in this study provided reliable results.

With the perspective of information management, on-going monitoring of the specified service function is one of the major activities and even critical process. The research consisted of three empirical research questions such as, the current usage and overall user-satisfaction, the quality of the R&D information content and the service, and the problems which have been observed by the actual user group of National Digital Science Library (NDSL). The results of the investigation provided several guidelines that can be utilized for the improvements of the R&D information user service as well as some recommendations for overall optimal administration.

The objective of this study is to identify key dimensions of e-service quality and explore their relations to user satisfaction at Public libraries. This research used a modified e-service quality model and surveyed Internet service users for measuring and assessing Internet users' service satisfaction at 'A' public library in Seoul region. Using an exploratory factor analysis. the study identified three factors, named Service Affect, Information Access, and Tangibles as key dimensions for public library e-service quality. Also it was found that users' satisfaction was strongly positively correlated to their intention to refer others to the service.

As users constitute one of the three components of a transportation system; and in many respects the most important component, user perception is a critical element within the concept of transportation services as transportation exists to provide high quality service to various user groups. However, this user perception has not been studied because it is difficult to be analyzed. The purpose of this study is to introduce the importance and alternative method to consider transportation user perception for various transportation engineering areas such as service quality and safety level of transportation system. For this purpose, various studies related to transportation user perception were reviewed. In addition, experiment results were analyzed to investigate the characteristics of transportation user perception.

최근 보급되고 있는 스크린 야구장을 많은 이용자가 단순한 타격만을 하고 피드백이 없이 일회성으로 이용하고 있고 이용자의 타격 자세를 평가해주는 기능을 제공하지 않고 있다. 부정확한 자세로 타격을 하게 되면 부상의 위험도 있고, 타격 실력도 향상될 수 없다. 따라서 이용자가 올바른 타격자세를 취할 수 있도록 자세를 평가 해주는 시스템이 필요하다. 본 논문에서는 구글의 미디어 파이프와 딥러닝 기술을 활용하여 타격 자세 영상을 인식하여 타격 자세를 평가해주는 시스템을 개발하였다. 제안한 시스템은 사전에 다양한 영상을 LSTM 알고리즘으로 학습하여 이용자의 타격자세를 4개 등급으로 평가해준다. 이를 활용하여 스크린 야구장에서 카메라만 설치하여 간단하게 사용 가능하며 이용자들이 타격 자세를 자체 평가할 수 있다.

Diverse disciplines such as information science, computer science, cognitive science, and industrial design, are activity engaged in the website evaluation research efforts. Information scientists emphasize the importance of user-centered and user-friendly website design, which is also easy to use, This idea is based on the understanding that the users and the designers are different set of people. In addition, information scientists consider the practice of maximally incorporating user inputs during the website design to be very important guideline. However, this study is based on a newly emerging population of website users who are also designers. 218 study participants evaluated the websites that they designed in comparison to the websites designed by others. According to the survey data analysis, the study participants considered the content delivery, design simplicity, design consistency, and link access of the websites to be equally important from both users' and designers' perspectives. However, the content organization, rich content, and screen composition were underestimated from the designers' point of view whereas these factors were considered to be important from users' point of view.
