The key role in safety management is to identify any possible hazard before it occurs by identifying any possible risk factors which are critical to risk assessment. This planning/assessment process is considered to be tedious and requires a lot of attention due to the following reasons: firstly, falsework (temporary structures) in construction projects is fundamentally important. However, the installation and dismantling of those facilities are one of the high risk activities in the job sites. Secondly, temporary facilities are generally not clearly delineated on the building drawings. It is our strong belief that safety tools have to be simple and convenient enough for the jobsite people to manage them easily and be flexible for any occasions to be occurred at various degrees. In order to develop the safety assessment system, this research utilizes the BIM technology and collects important information by importing data from BIM models and use it in the planning stage.

In this paper, we analyze the performance of the network management system with intelligent mobile agent system. The proposed system dynamically selects appropriate its destinations. Thus, the system has an advantage of flexible network management in mobile network environments as well as dynamic change of traffic. Comparing its delay and throughput performance with the conventional SNMP based network management system, we find that the proposed mobile agent system performs better efficiency than the conventional one.

This paper describes the instructional flexible manufacturing system(FMS) laboratory facility at Virginia Polytechnic Institute(VPI) which is directed at problems and issues in the design, implementation and control of computer integrated manufacturing systems. It begins with a configuration and an operational description of FMS laboratory facilities. Next, relevant curricula in manufacturing systems design and control, which can use the FMS laboratory for instructional purpose, are introduced, A computer simulation can be used as an excellent tool for analysis prior to implementation of FMS as well as an on-going improvement tool. A brief survey of simulation languages is lastly included.

Advent of the new European satellite positioning system, Galileo will result in development of new satellite receivers such as, GPS/Galileo dual mode receiver. Furthermore, a new GNSS satellite receiver would be required to be self-reconfigured to certain navigational environments like, indoor, high interference, integrity, etc. In this paper, design and implementation issue of a FPGA based flexible GNSS receiver which gets navigation solution using L1 band signals of GPS and Galileo simultaneously is addressed.

This study is conducted to formulate various spatial compositions for mixed-use elementary schools in order to use them as community centers. Accordingly, this study is conducted to analyze currently operating community-use elementary schools to find out about the current condition of mixed-use facilities, and the types of mixed-use facilities will be derived from the analysis. In addition, a more effective method of planning mixed-use elementary schools is investigated. By incorporating various educational curricula and teaching/learning activities, major points, which should be considered when planning elementary schools, will be suggested to effectively respond to the changes of educational environment in the future. The results show that in terms of inner traffic flow type, 9 schools out of the schools under study showed a unificated traffic flow type or a cross traffic flow type. When traffic overlaps, problems of noise, visual distraction, and decreased learning performance can appear. To prevent the conflict between areas and to manage areas effectively, each area should be differentiated by installing doors and shutters and by marking guides, and the facility used for community residents and students should also be scheduled separately to avoid time conflict. In addition, to accommodate the changes of users, flexible space planning options should be considered.

The purpose of this study is to produce the architectural basic data for the planning of Kindergarten attached to the elementary school. For this study, 19 Kindergartens in Taegu city was selected and investigated as the sample of the survey. The results of this study are as follows. 1) 'The Independent-type' can be general application of the kindergarten's layout type. And it must be considered about connection with some public facilities in the elementary school. 2) The architectural guidelines for each rooms can be suggest as follow. Classrooms and the Playroom should be existed independently and be located about suitable area. The Location of the Playground should be considered about kindergartener's approach, distance from elementary school and noise. And the Playground needs washstands and shade resting places. In the Classrooms and the Playroom, the designer should consider about suitable area and storage. 3) The flexible space-program is necessary for each management type.

The costs of solid waste management have continued to increase. Stricter environmental regulations have been applied to waste management units. Future integrated solid waste management should be balanced between source reduction, recycling, energy recovery, and land disposal. To achieve more balanced solid waste management programs, more local governments must adopt diversion and recycling goals and finance to meet those goals. The hierarchy of integrated solid waste management must be enforced in a manner that is flexible enough to allow local governments to implement waste management facilities that match the communities' ability to pay for them. In establishing a hierarchy of integrated solid waste management, local governements have difficulties in implementing source reduction and recycling because of a lack of local control and inability to pay for new facilities. Integrated solid waste management involves selecting compatible options for facilities to manage the collection, recovery of energy and materials(transformation), and disposal of solid wastes efficiently. Waste Collection, transformation, and disposal must support source reduction and recycling activities.

Background/Aims: In March 2022, the Association for the Advancement of Medical Instrumentation (AAMI) released the American National Standards Institute (ANSI)/AAMI ST91:2021, their latest update on comprehensive, flexible, and semirigid endoscope reprocessing. These updated standards recommend the sterilization of high-risk endoscopes when possible and provide new recommendations for the precleaning, leak testing, manual cleaning, visual inspection, automated reprocessing, drying, storage, and transport of endoscopes. Methods: ANSI/AAMI ST91:2021 was compared with ANSI/AAMI ST91:2015 for major reprocessing differences that result in either time and/or cost increases. Time estimates were captured by explicit recommendation inclusion or taken from the literature. All the costs were estimated using publicly available resources. Results: The updated standards represent a potential 24.3-minute and 52.35 to 67.57 United States dollars increase per procedure in terms of reprocessing time and spending, respectively, not including capital investments. Capital costs per procedure were highly dependent on the procedure volume of the facility. Conclusions: The new AAMI standards recommend several major changes, such as sterilization, for facilities to reprocess and manage endoscopes between uses. As more facilities increase their reprocessing methods to reflect the updated standards, they do so at a cost and introduce several delays. As the reprocessing landscape evolves, facilities should consider their true costs and alternative solutions, such as single-use endoscopes.

최근 건설 산업은 BIM (Building Information Modeling)의 도입으로 인하여 많은 혜택을 얻고 있다. 하지만 도로나 철도와 같은 선형기반 설계공종의 경우는 구간별 표준횡단면의 정의와 선형의 배치를 통한 서피스(surface)모델을 생성함으로써 3차원 설계가 이루어지나, 현재 설계 소프트웨어에서 제공되는 횡단면 설계요소가 제한적이거나 국내실정에 맞지 않은 점이 많고, 생성된 서피스모델은 선형구간의 시 종점에 대해 일체화 되어있어 공정, 물량, 단가 등의 BIM 소요정보와 세분화된 연계를 위해서는 모델 수정 등의 많은 후속작업이 필요하다. 본 논문에서는 이러한 문제점을 해결하기 위하여 3D 선형기반설계가 적용되는 사회기반시설물을 대상으로 3차원 모델의 분절 및 속성정보의 운용이 자유로운 '선형기반 인프라시설물을 위한 Flexible BIM 시스템'의 설계를 통하여 BIM의 활용성을 극대화 하는 것을 목표로 한다.
