  • The national management and retrieval service of the national scholar Content DB are very important. High quality content can improve the user's utilization and satisfaction and be a strong base for both the citation index creation and the calculation of journal impact factors. Therefore, the system is necessary to check data quality effectively. We have closely studied and developed a webbased data quality checking system that will support anything from raw digital data to its automatic validation as well as hands-on validation, all of which will be discussed in this paper.

  • This paper deals with automated computer-aided process planning by which designers can determine operation sequences even if they have little experience in the design of press working products. The computer-aided process planning in hot forging, deep drawing and blanking requires many kinds of technical and empirical skills based on investigation and collection of the knowledge of their processes. An approach to the CAPP system is based on the knowledge-based rules and the process knowledge base consisting of process planning rules is built. The methodology adopted to develop the system is elaborated in this paper. This system has been written in AutoLISP on the AutoCAD with a personal computer and provides powerful capabilities for process planning of hot forging, cold forging, deep drawing and blanking products.

  • Under a knowledge-based economy, regional innovation policies have been treated as important regional policies. In this paper, the author attempts to argue the possibilities and problems for regional innovation in Japan. For this purpose, the author has investigated the development of industry-academy-government collaboration in Ube City which has been designated as one of a number of knowledge cluster projects by the National Government. Ube City is a typical company town and the regional system had been characterized by the vertical relationship between a core company and it's subcontractors. Since the late 19905, the local national university has played an important role to promote cooperation with various types of enterprises, research institutions, and local governments. As such horizontal relationships have become more influential, it is necessary to overcome the gap in interest and knowledge base between the core company and the local university.

  • Recently, research on Media Access Control (MAC) techniques for underwater acoustic communication has been conducted actively. For successful acoustic communication in underwater conditions, development of environmentally adaptive MAC techniques, which is taking narrow bandwidth, distance, depth, noise level, salinity, multipath and etc into account, is an especially important work. In this paper, knowledge based system is introduced not only to obtain adaptive and optimal communication parameters but also increase network efficiency and availability by requesting change of MAC techniques based on decisions from knowledge-based system Smart Decision Block (SDB). Computer simulations were also conducted to verify the performance of the proposed system in underwater conditions.

  • Objectives: The purpose of this study was to evaluate the effects that appeared to parents after conducting a dental caries management program for 12 months using a mobile application for systematic caries management of children. Methods: Parents responded to a questionnaire on oral care self-efficacy and oral health knowledge at the baseline, and received feedback on a management program suitable for their child's caries risk group for 12 months through a mobile application. At the end of 12 months, the questionnaire was re-written. Results: The self-efficacy of oral care increased in the low risk group, and oral care knowledge and program satisfaction were highest in the parents of low risk children. Conclusions: Base on the results of the this study, It was confirmed that parents' self-efficacy, knowledge, performance and satisfaction were all positively evaluated through the oral care program using a mobile application.

  • This study proposes a dependency grammar-based self-attention multilayered bidirectional long short-term memory (DG-M-Bi-LSTM) model for subject-predicate-object (SPO) tuple recognition from natural language (NL) sentences. To add recent knowledge to the knowledge base autonomously, it is essential to extract knowledge from numerous NL data. Therefore, this study proposes a high-accuracy SPO tuple recognition model that requires a small amount of learning data to extract knowledge from NL sentences. The accuracy of SPO tuple recognition using DG-M-Bi-LSTM is compared with that using NL-based self-attention multilayered bidirectional LSTM, DG-based bidirectional encoder representations from transformers (BERT), and NL-based BERT to evaluate its effectiveness. The DG-M-Bi-LSTM model achieves the best results in terms of recognition accuracy for extracting SPO tuples from NL sentences even if it has fewer deep neural network (DNN) parameters than BERT. In particular, its accuracy is better than that of BERT when the learning data are limited. Additionally, its pretrained DNN parameters can be applied to other domains because it learns the structural relations in NL sentences.

  • Grinding is used for machining high precision parts with high additional value. However, the grinding operation needs high skill and long experience of an operator because of a lack of the scientific knowledge and engineering principles. Also, the wheel and grinding conditions affect grinding results. For these reasons, it is difficult to construct computer integrated manufacturing system(CIMA). Therefore, it is necessary for Expert System to be informed of qualitative knowledge of grinding expert's skills and experiences. In this research, the Grinding Expert System is constructed by Fuzzy Decision Making Algorithm. Using this system, unskilled workers will be able to use the knowledge and experience of an expert.

  • Recently, the volume of knowledge information in the form of electronic media is quickly increasing in the library field along with the advancement of electronic communication technology. Libraries have both printed data and electronic data and are faced with the issue of corresponding with the access and use of knowledge information in terms of the space. This study is for building the layout of a sustainable knowledge information space based on the view that the library is the official infrastructure of the knowledge information based society. It is intended to analyze the meaning of knowledge information in the modern society, characteristics in the spatial organization and the transmission of knowledge information. The goal of this study is to understand and forecast the spatial structure where users access knowledge information and exchange with one another and developing the direction and guidelines for the spatial plan that today's libraries prefer through this analysis. For this, this study firstly prepared the base for the research on library space which can be considered as the physical realization of such concepts, through the theoretical review about the knowledge information and social concepts as well as characteristics of modern society. Also, it seized the characteristics in the transmission of knowledge information by conducting a structural analysis of the information service such as knowledge information and space, space and information media, space and space through the cases of 10 public libraries. The analysis resulted in basic data including the system of organizing knowledge information, system of knowledge information transferring elements and structure, and layout pattern of each library. These results are deemed meaningful for the promotion of communication with the user through the exchange, creation, and experience of knowledge information, the social role of today's public library.
