  • ERP in the past, primarily centering on large enterprises and the introduction of competition in the global e-business, but along with the proliferation of small and medium-sized enterprises are now in earnest, or to take advantage of the introduction of the ERP plan. However, the introduction of the ERP cost and the effort required to develop, because many never previously introduced ERP expect that the introduction of cost and performance comparisons with the measurement is necessary. Until now, however, the introduction of a framework of analysis followed the introduction of ERP primarily to measure performance of a major improvement. This research, in addition to improving the performance of these tasks have been overlooked until now for the system's user satisfaction BSC (Balanced Scorecard) models and techniques using AHP-specific understanding of the Company (Group executives, middle managers groups, and user groups) Importance of priorities you want to analyze. In summary, the key findings of this study follows. First, ERP user satisfaction measurement for the balanced scorecard indicators in terms of the redevelopment. Second, the information system user satisfaction to the user layer (Layer 3), grouped by the measure. Thirdly, the user satisfaction of the important topics for attention as quantified by measuring the hierarchy. This model is for satisfaction levels as quantitative of future users of the new system, information systems and the introduction of a new model of development based on the evaluation data will be able to take advantage of.

  • Purpose This study empirically examined the causal relationships among the level of advanced manufacturing technology(AMT), facilitation of alignment, the degrees of strategic alignment of management accounting information systems(MAIS), and the improvement of production performance. Design/methodology/approach Data for this study were drawn from a survey of the current status of AMT used in Korean manufacturing firms. At the beginning, 131 organizations responded to the request for information. However, during the survey, 5 firms withdrew from the survey, and as a result, 126 manufacturing firms were included in the research. In order to collect data, this study administered questionnaires with the participating firms. The survey was conducted during a 4-month period between November 2015 and March 2016. Findings The results showed that the level of AMT has a significant impact on alignment facilitation. A significant causal relationship between alignment facilitation and MAIS strategic alignment was also found. It was shown that under high degrees of MAIS strategic alignment, MAIS must provide broad-scope and integrated types of information. The causal relationships between MAIS strategic alignment and organizational performance were significant and positive. Thus, it is concluded that under high levels of AMT, a high degree of MAIS strategic alignment positively contributes to the improvement of a firm's production performance.

  • This study is to propose the characteristics that a desirable quality, especially usability, evaluation method of hospital information systems(HIS) should possess. This study reviews the literature recently published in the academic journals which are in the Science Citation Index or registered by the Korean Research Foundation. Especially, the International Journal of Medical Informatics was the valuable source, providing almost 20 literature. The results reveal the need to develop a domain-specific usability evaluation method that reflects the uniqueness of hospital industry. The results show user-centeredness and context-orientedness are the indispensible characteristics of a HIS quality evaluation method too.

  • The purpose of this paper is to investigate search efficiency of controlled vocabulary versus uncontrolled vocabulary subject access in online catalog systems. The question of the effectiveness of controlled versus uncontrolled vocabulary in information retrieval has been raised in many literatures. A debate continues in the Library and Information Science Professions over the relative merit, appropriateness, and efficiency of uncontrolled vocabulary subject access in online catalog systems. Actually users used to combine uncontrolled vocabulary subject searching with controlled vocabulary subject searching. But the success of user's subject search depends on his choice of search terms. Also the technical developments that facilitate cooperation among information services in general make it increasingly possible for such cooperation to take place on an international level. In this study, several common types of vocabularies on online catalog systems are described and compared, especially usages of vocabularies in multilingual environment are analyzed.

  • Today the theme of "IT Architecture" has become a topic of special interest in both public and private sectors. Based on the literature survey on information systems planning and information architecture, IT architecture may be viewed as the outcome of evolution, rather than revolution. A case study was conducted in order to compare the tasks and deliverables of U.S. IT architecture and Korean Information Strategy Planning. No significant differences were found in tasks or deliverables. Implications of the study were discussed.

  • In the field of computer vision, visual surveillance systems have recently become an important research topic. Growth in this area is being driven by both the increase in the availability of inexpensive computing devices and image sensors as well as the general inefficiency of manual surveillance and monitoring. In particular, the ultimate goal for many visual surveillance systems is to provide automatic activity recognition for events at a given site. A higher level of understanding of these activities requires certain lower-level computer vision tasks to be performed. So in this paper, we propose an intelligent activity recognition model that uses a structure learning method and a classification method. The structure learning method is provided as a K2-learning algorithm that generates Bayesian networks of causal relationships between sensors for a given activity. The statistical characteristics of the sensor values and the topological characteristics of the generated graphs are learned for each activity, and then a neural network is designed to classify the current activity according to the features extracted from the multiple sensor values that have been collected. Finally, the proposed method is implemented and tested by using PETS2013 benchmark data.

  • It is quite a necessity for the small and medium corporations(Abbre : SMC) to have information technology in order to survive in ever changing global business environment . Especially recently, the importance and uses of Internet have greatly increased by SMCs facing changing environment. This thesis aims to propose various application alternatives of Internet through the analysis of the Internet uses by SMCs. For the analysis, questionaires were distributed nationally to 126 small and medium corporate entities, and 64 out of 82 retrived questionaires have been used for the analysis. The analysis revealed several notable points related with Internet applications by SMCs that , although SMCs strongly feel the need for the use of Internet. -the level of recognition for the existence of the Internet was relatively low -the time used was also at low level -the job which uses Internet was mainly marketing related -and the fields applied were concentrated in those of search and e-mail. The benefits which are derived from the use of Internet include swift provision of technological information to SMCs ,improvement of active interchanges of information through the whole relate networks, strengthened promotion of products made by Internet to promote smooth communications (among related divisions or personnels), to automate work systems , and to systemizestrategic management planning process etc. Consequently, it is expected that, althgough the level of application of Internet is quite low, Internet can be served as a source of information technology and futher as a weapon to better combat strong competition through various supports at government level, since small and medium corporations feel its strong need for Internet.

  • Documents contain information that can be used for various applications, such as question answering (QA) system, information retrieval (IR) system, and recommendation system. To use the information, it is necessary to develop a method of extracting such information from the documents written in a form of natural language. There are several kinds of the information (e.g., temporal information, spatial information, semantic role information), where different kinds of information will be extracted with different methods. In this paper, the existing studies about the methods of extracting the temporal information are reported and several related issues are discussed. The issues are about the task boundary of the temporal information extraction, the history of the annotation languages and shared tasks, the research issues, the applications using the temporal information, and evaluation metrics. Although the history of the tasks of temporal information extraction is not long, there have been many studies that tried various methods. This paper gives which approach is known to be the better way of extracting a particular part of the temporal information, and also provides a future research direction.
