    Structural health monitoring (SHM) is a technique to diagnose an accurate and reliable condition of civil infrastructure by collecting and analyzing responses from distributed sensors. In recent years, aging civil structures have been increasing and they require further developed SHM technology for development of sustainable society. Wireless smart sensor and network technology, which is one of the recently emerging SHM techniques, enables more effective and economic SHM system in comparison to the existing wired systems. Researchers continue on development of the capability and extension of wireless smart sensors, and implement performance validation in various in-laboratory and outdoor full-scale experiments. This paper presents a summary of recent (mostly after 2010) researches on smart sensors, focused on the newly developed hardware, software, and validation examples of the developed smart sensors.ope

    Use of Model-Free and Zero-Setup Computer-Guided Implant Surgical Template for Partial Edentulous Cases

    This case report presents the cases of single anterior missing and posterior free-end edentulous ridge with computer-guided implant placement on the day of visit through a special tray containing fiducial markers without model scan or intraoral scan data. Cone beam CT was taken after fixing the marker embedded ready-made tray with a photopolymerized resin material by light-curing in the patient's mouth. The implant location was planned on the registered CT data in the planning software. The tool path calculation for the milling machine was conducted in the computer-aided manufacture (CAM) software. The guide was completed by milling the drill hole in the special tray as designed. Although the preparation for the conventional implant guide surgery takes considerable time, including data acquisition and 3D printing, it was possible to produce a guide on the day of the patient visit without a separate procedure other than a CT scan through this protocol. Also, the transfer of the implant surgery plan, the process of scanning and 3D printing, was omitted, thereby reducing the positional error between the CT data and the actual guide.ope

    A Study on the Development and Effectiveness of ISO13485: 2016 Education Programs for Domestic Medical Device Manufacturers

    Get PDF
    Purpose As ISO 13485 was revised in 2016, the domestic GMP (Good Manufacturing Practice) system was also revised and implemented in 2019. However, there are many problems in the domestic medical device industry because most of the small and medium-sized enterprises lack human and material resources. Accordingly, this study was conducted to provide education programs for domestic medical device companies to induce information provision and improve the companyโ€™s quality management ability. Methods First, analyze existing education. Second, based on the revised GMP system, a survey paper was produced to investigate difficulties and problems experienced by companies. Third, a two-week survey was conducted on domestic medical device manufacturers, and a total of 77 companies responded to this survey. Fourth, educational program development was conducted based on the results of the survey. Results and Conclusion The developed education program consists of a total of five sessions. In this study, the educational program developed by grasping the needs of the company through a survey consists of a total of five sessions. The first session consisted of theoretical education and the second to fifth sessions of practical education. Through the education program developed in this study, it is expected to contribute to the overall development of medical device quality by establishing a domestic medical device manufacturing environment that secures the safety and performance of domestic medical device companies.ope

    Design and Implementation of a Relational Database for Management of UML Models

    Get PDF
    The UML (Unified Modeling Language) is a modeling language for specifying, visualizing, constructing, and documenting systems. It also supports systematically the design and development of systems. There may be a large number of models to be managed in a real modeling environment. A methodology to save and retrieve the models effectively, therefore, needs to be developed. This thesis focuses on the class diagram which is the core part of UML. It proposes a database supported methodology for the management of class diagrams. In the proposed methodology, class diagrams are saved in and retrieved from a relational database. To save a class diagram in the database, the constitution of the class diagram is translated in terms of relational tables. To retrieve a class diagram from the database, the user- specified query is translated into the SQL (Structured Query Language), and then the constituent of the class diagram is searched from the tables in the database. The proposed methodology can exploit the function of the relational database such as managing a large number of models, sharing the models among users, and fast queries. It, therefore, provides a powerful framework for an effective management of UML models and a fast development of systems.Abstract = โ…ฑ ์ œ 1 ์žฅ ์„œ๋ก  = 1 ์ œ 2 ์žฅ UML ๋ฐ UML ๊ฐœ๋ฐœ ๋„๊ตฌ = 4 2.1 UML์˜ ๊ตฌ์„ฑ ์š”์†Œ = 4 2.2 UML ํด๋ž˜์Šค ๋‹ค์ด์–ด๊ทธ๋žจ(Class Diagram) = 6 2.2.1 ํด๋ž˜์Šค(Class)์™€ ์ธํ„ฐํŽ˜์ด์Šค(Interface) = 7 2.2.2 ๊ด€๊ณ„(Relationship) = 8 2.3 UML ๊ฐœ๋ฐœ ๋„๊ตฌ = 10 ์ œ 3 ์žฅ UML ํด๋ž˜์Šค ๋‹ค์ด์–ด๊ทธ๋žจ์˜ ์ €์žฅ ๋ฐ ๊ฒ€์ƒ‰ = 12 3.1 UML ํด๋ž˜์Šค ๋‹ค์ด์–ด๊ทธ๋žจ ๋ณ€ํ™˜ = 12 3.2 ๊ด€๊ณ„ํ˜• ๋ฐ์ดํ„ฐ๋ฒ ์ด์Šค ์ƒ์„ฑ ๋ฐ ์ €์žฅ = 17 3.3 UML ํด๋ž˜์Šค ๋‹ค์ด์–ด๊ทธ๋žจ ๊ฒ€์ƒ‰ = 21 ์ œ 4 ์žฅ ๊ตฌํ˜„ ๋ฐ ๊ธฐ์กด ์‹œ์Šคํ…œ๊ณผ์˜ ๋น„๊ต = 23 4.1 ์•Œ๊ณ ๋ฆฌ์ฆ˜ ๋ฐ ์‹œ์Šคํ…œ ํ๋ฆ„๋„ = 23 4.2 ๋ฐ์ดํ„ฐ๋ฒ ์ด์Šค ํ…Œ์ด๋ธ” ์ƒ์„ธ ์„ค๊ณ„ = 26 4.3 ์‹œ์Šคํ…œ ๊ตฌํ˜„ = 33 4.4 ๊ธฐ์กด ์‹œ์Šคํ…œ๊ณผ์˜ ๋น„๊ต = 35 ์ œ 5 ์žฅ ๊ฒฐ๋ก  ๋ฐ ํ–ฅํ›„ ์—ฐ๊ตฌ๊ณผ์ œ = 36 ์ฐธ๊ณ  ๋ฌธํ—Œ = 3
