  • The purpose of menu labeling is to offer eating environments with improved healthy food selection. Similar to U.S. policies, the Korea government enforces the Special Act on Children's Food Safety and Nutrition for provision of nutritional labeling in chain restaurants. Considering the importance of dining services for college students and their interests in health, this study examined college students' perception toward nutrition information provided by university dining services. A survey was conducted for university students. Students' recognition of nutrition information for university dining services was lower than recognition of nutrition information for commercial food services. The most common reason cited by students for considering nutrition information of university dining services was customer rights, followed by health maintenance. Students showed a high tendency to use nutrition information of university dining services. College students' motivation for knowing nutrition information of university dining services included health and value interests. Students' knowledge of nutrition had a positive effect on their intention to know nutrition information. The findings of this study offer university administrators and contract food service management companies directions for developing menu labeling for university dining services.

  • Globalization of the industry induces the internationalization of any given manufacturing company's supply chain. Development of e-Commerce and Information Technology (IT) changes the logistics structure, making logistics information systems essential. Web-based connectivity and supply chains based on new technologies are becoming essential in the logistics industry. Customers are driving the implementation of systems to ensure timely, thorough, and accurate information, often with immediate access; in response, the Internet has propagated tracking and tracing systems. Value-added services are the key to successful intermediary activities. The nationwide Integrated Logistics Information System (ILIS) aimed to utilize existing and future information infrastructure and knowledge bases to build an integrated logistics information network that would provide comprehensive logistics information services for shippers and carriers in order to improve the efficiency of both inventory and information flows in their supply chains. The ILIS, as one of the seven national information networks, has provided various services, particularly services related to import/export and clearance. Though a survey concerning logistics information services shows rather positive results, shippers and carriers still require better services and reductions in EDI prices. Therefore, the role of the ILIS needs to be re-defined. Short-term plans for the ILIS contain ICD services and XML/EDI services, which are described in detail.

  • This study proposed to develop a model for user-customizable policy information services, based on an assessment of policy users' demands and a case analysis of customized services. To do this, we analyzed literature related to user customized services, performed case studies, and carried out a survey targeting policy information consumers. In this way, this study suggested that information retrieval and data offerings, reference information services, policy information network services, library marketing services, and personalized service are details which user-customizable policy information services must provide.

  • The construction of an information super highway and diffusion of the internet brings about a lot of changes in the Legislative Information Services of the National Assembly Library. In the same vein, Legislative Information Services should provide information services which satisfy users according to their information needs and the changes. In light of that, this study aims at enhancing users' satisfaction and suggesting information services for the Legislative Information Services of the National Assembly Library. Accordingly, this study surveys assemblymen and their assistants of satisfaction in Legislative Information Services and suggests some recommendations for improvement based on the survey results.

  • This study investigates both arbitrariness and misrepresentation in the terminology of Korea's LIS field with an example of the term 'information services.' The focus is on analyzing the differences in the Term's history and theoretical base between American LIS field and Korea's. Discussed in details are the popularity and usage of the Term in Korea's LIS field and libraries. The ultimate intention of this study is to motivate the Korea's LIS scholars to endeavor for theoretical accomplishments with regard to 'information services,' which can justify the change of term from 'reference services' to 'information services.'

  • Web services instances can be classified into two categories, namely trusted and untrusted from users. A web service with high throughput (TP) and low response time (RT) instance values is a trusted web service. Web services are not trustworthy due to the mismatch in the guaranteed instance values and the actual values achieved by users. To perform web services selection from users' attained TP and RT values, we need to verify the correct prediction of trusted and untrusted instances from invoked web services. This accurate prediction of web services instances is used to perform the selection of web services. We propose to construct fuzzy rules to label web services instances correctly. This paper presents web services selection using a well-known machine learning algorithm, namely REPTree, for the correct prediction of trusted and untrusted instances. Performance comparison of REPTree with five machine learning models is conducted on web services datasets. We have performed experiments on web services datasets using a ten k-fold cross-validation method. To evaluate the performance of the REPTree classifier, we used accuracy metrics (Sensitivity and Specificity). Experimental results showed that web service (WS1) gained top selection score with the (47.0588%) trusted instances, and web service (WS2) was selected the least with (25.00%) trusted instances. Evaluation results of the proposed web services selection approach were found as (asymptotic sig. = 0.019), demonstrating the relationship between final selection and recommended trust score of web services.

  • Currently, it is not easy for most domestic public libraries to collect and provide reliable health information services on their own. Health information is distributed or professional, making it inconvenient for users to use. Based on the implications derived from the case study, the Library Health Information Integration Service Model was proposed as a specialized information service. The model consists of a composition shared by librarians, health and medical experts, and users, focusing on library websites that provide integrated health information integration services, and has the following features. First, it provides health and medical information on a specialized subject. Second, it provides integrated health and medical information services provided in various ways. Third, librarians and health and medical experts work together to provide information services. Fourth, users can freely use health information integration services online and offline. The model presented in this study means that libraries can play a leading role in health information integration services to increase the utilization rate of public libraries and further contribute to librarians serving as experts in health information services.

  • The proposed conceptual framework is based in the relationships among knowledge of personal information security, trust on the personal information security policies of parcel delivery service companies, privacy concern, trust in and risk of parcel delivery services, and user satisfaction with parcel delivery services. Drawing upon both cognitive theory of emotion and cognitive emotion theory that complement each other, we propose a research model and examine the relationships between cognitive and emotional factors and the usage of parcel delivery services. The proposed model is validated using data from customers who have previously used parcel delivery services. The results show a significant relationship between the cognitive and affective factors and the usage of parcel delivery services. This study enhances our understanding of parcel delivery services based on the consumers' psychological processes and presents useful implications on the importance of privacy and security in these services.
