BACKGROUND/OBJECTIVES: With the advances in technologies, self-service kiosks at foodservice operations are becoming a new way of service provision. This study examined the relationships among the menu information quality, nutrition information quality, technology acceptance characteristics, and customer behavioral intention toward the kiosks in fast food restaurants. SUBJECTS/METHODS: A survey with a self-administered method was distributed online and offline. The sample consisted of customers who had used the kiosks at fast food restaurants in the last six months prior to the survey. The study hypotheses were tested by applying structural equation modeling. RESULTS: Structural equation modeling revealed the positive impacts of menu information quality and nutrition information quality, technology acceptance characteristics, and behavioral intention toward kiosks at fast food restaurants. On the other hand, one hypothesis (Hypothesis 4) on the impact of nutrition information quality on the perceived usefulness was rejected. CONCLUSION: The study is the first to investigate nutrition and menu information at foodservice kiosks and relate them to technology acceptance. The study is very timely and adequate in the time of the 4^th industrial revolution. The critical importance of the presentation of nutrition information and menu information at the kiosks at fast food restaurants was verified. The academic and industrial implications of the study findings were discussed.

Digital platforms characterized by network effects enable provisioning of various types of services and provide a mechanism for linking producers and consumers. Identifying the key Quality of Service attributes of such platforms is vital for their continued success and growth. In this paper, a set of quality attributes for platforms is first extracted from different extant quality models. Then actual user feedback data from three platform providers are analysed and mapped against the set of quality attributes to determine the key attributes that are relevant. These findings are corroborated with qualitative data from interviews of different stakeholders. The results show that service quality characteristics are important to the success of platforms. Functional characteristics of platforms assume importance where the digital contributions of the platform is higher. Apart from these, 'fitness for use' as a major determinant of quality is also important in digital platforms.

This study examined the factors that make Korean companies adopt supply chain management systems. By adding a group of inter-organizational factors, we extended an innovation-theory-based research model to study the information technology adoption. Sixty three questionnaires from 700 leading companies in Korea were collected and analyzed. Independent variables of the research included environmental, organizational, innovation, and relational characteristics. We found that supply chain management systems in Korean companies are at the initial stage of the adoption, in general. This research also found that company's environmental characteristics have insignificant relationship with the adoption of supply chain management systems. In addition, organizational characteristics (the support of top management, the size of organization, and the information technology infrastructure), innovation characteristics of the supply chain, and the power exercised over the supply chain played important roles in adopting supply chain management systems.

The properties of a scale-free network are little known; its node degree following a power-law distribution is among its few known properties. By selecting real-field scale-free networks from a network dataset and comparing them to other networks, such as random and non-scale-free networks, the topology characteristics of scale-free networks are identified. The assortative coefficient is identified as a key metric of a scale-free network. It is also identified that most scale-free networks have negative assortative coefficients. Traditional generation models of scale-free networks are evaluated based on the identified topology characteristics. Most representative models, such as BA and Holme&Kim, are not effective in generating real-field scale-free networks. A link-rewiring method is suggested that can control the assortative coefficient while preserving the node degree sequence. Our analysis reveals that it is possible to effectively reproduce the assortative coefficients of real-field scale-free networks through link-rewiring.

Characteristics of Al cathode films deposited by using specially designed twin target sputter (TTS) system were investigated. It was found that Al cathode films prepared by TTS were amorphous structure with nanocrystallines due to low substrate temperature and OLEDs fabricated using TTS system have low leakage current density at reverse bias because of effective confinement of energetic particles during sputtering process.

Trade Portal Site(TPS) is one of the innovative skills which makes it possible for small and medium-sized enterprises(SMEs) to manage international trade activities more efficiently by using the newest information and telecommunication technology. Based on performance and an existing research related to using information technology, this research analyzed the user's degree of utilization of TPSs which moderates effects between SMEs characteristics and export performance of SMEs. According to the results of the empirical study on actual data of 194 sample firms by using moderated regression analysis, there are significant only organizational characteristics among determinants(such as organizational characteristics, export characteristics) as the degree of utilization of TPSs. These research results provide many useful insights to the CEOs of SMEs using the services of TPSs, e-Trade system developers, and government policy makers. First, CEOs and managers of SMEs should have thorough understanding of the importance of the new information technology and e-Trade and positively adopt new e-Trade solutions and systems to their export processes to enhance global competitiveness. Second, TPS managers and e-Trade systems developers must concentrate on improving the user's degree of utilization of TPSs. Finally, the government agency should develop the various e-Trade promotion policies to support the efforts of SMEs organizational characteristics and TPS to increase the degree of utilization of TPS, which have positive effects on the export performance of SMEs.
