BIM은 건설산업의 생산성 향상을 견인할 핵심기술로 부상하고 있으나 이에 따른 작업 패러다임의 전환은 중소규모의 업체들이 감당하기 어려운 수준의 변화를 요구하고 있다. BIM 플랫폼을 통해 기존의 2D CAD 환경과는 비교하기 힘든 다양한 기능의 수행을 기대할 수 있으나, 이를 위해 수반되는 고가의 프로그램 및 시스템 구축 부담은 BIM 적용을 주저하게 하는 걸림돌이 되고 있다. 이에 따라 본 연구에서는 Revit, MS Project, Navisworks 등 기본적인 BIM 프로그램으로 생성한 건물정보와 Excel VBA를 이용한 사용자화 과정을 통해 공정을 검토하고 일정에 따른 소요물량을 파악할 수 있도록 하는 사용자 맞춤형 4D 및 5D 시스템을 구현하였다. 이를 통해 사용자 맞춤형 4D 및 5D 시스템을 구현하기 위해 필수적으로 요구되는 BIM 정보를 규명하고 도출한 BIM 정보를 활용하는 사용자의 요구에 맞게 사용자화하는 과정을 정립함으로써 BIM 정보의 활용을 통한 사용자화 구현 사례를 제공하고, 지역의 중소규모 업체들에게 BIM의 실무적 활용을 위한 실현가능한 현실적 대안을 제시하고자 한다.

다문화 가정의 정보 격차의 주요 원인인 언어장벽은 다문화 가정 자녀의 낮은 교육수준과 높은 연관성을 가지며, 경제불균형을 높임으로써 추가적인 사회문제화가 될 것으로 예상된다. 다문화가정 학부모는 디지털 기기에 대한 접근성과 자료 활용 능력이 일반국민에 비해 현저하게 떨어지는 정보격차로 인해 기존의 교육 콘텐츠의 효과적 활용은 제약점을 갖고 있다. 이러한 제약점을 해결하기 위해서는 학습자의 이해수준에 적합한 콘텐츠를 제공하는 맞춤형 학습콘텐츠 지원체제의 구축은 필수적이다. 이 논문에서는 다문화가정 학부모의 정보격차 해소를 위한 한한변환 기반 학습콘텐츠 시스템을 설계하고 이를 위한 사용자 맞춤형 학습콘텐츠 지원을 위한 한한변환 시스템의 프로토타입을 결과로 제시한다.

Background/Objectives: This paper proposes a dual mode feedback-controlled cycling system for children with spastic cerebral palsy to rehabilitate upper extremities. Repetitive upper limb exercise in this therapy aims to both reduce and analyze the abnormal torque patterns of arm movements in three- dimensional space. Methods/Statistical analysis: We designed an exercycle robot which consists of a BLDC motor, a torque sensor, a bevel gear and bearings. Mechanical structures are customized for children of age between 7~13 years old and induces reaching and pulling task in a symmetric circulation. The shafts and external frames were designed and printed using 3D printer. While the child performs active/passive exercise, angular position, angular velocity, and relative torque of the pedal shaft are measured and displayed in real time. Findings: Experiment was designed to observe the features of a cerebral palsy child's exercise. Two children with bilateral spastic cerebral palsy participated in the experiment and conducted an active exercise at normal speed for 3 sets, 15 seconds for each. As the pedal reached 90 degrees and 270 degrees, the subject showed minimum torque, in which the child showed difficulty in the pulling task of the cycle. The passive exercise assisted the child to maintain a relatively constant torque while visually observing the movement patterns. Using two types of exercise enabled the child to overcome the abnormal torque measured in the active data by performing the passive exercise. Thus, this system has advantage not only in allowing the child to perform the difficult task, which may contribute in improving the muscle strength and endurance and reducing the spasticity but also provide customizable system according to the child's motion characteristic. Improvements/Applications: Further study is needed to observe how passive exercise influences the movement characteristics of an active motion and how customized experiment settings can optimize the effect of pediatric rehabilitation for spastic cerebral palsy.

This paper discusses management education by utilizing the cyber education learning system in a web-based. New learning system tools offer great promise for a new contents of management learning. The cyber education learning system a shift from face-to-face lecturing to interactive learning. The situation changes profoundly when information technology becomes develope and education paradigm is shift. By exploiting the digital media. educations, and students, managers can shift to a new, more effect cyber education learning system. The following shift from classic educations to cyber educations learning system: from instruction to construction, from teacher-centered to learner-centered, from school to lifelong, from one-size-fits-all to customized, from teacher as transmitter to teacher as facilitator. Cyber education learning system has an important role to play in management education. Web-based technology is regarded as a general solution to cyber education learning. This study discussed many factors of implementation in cyber education systems and provide utilizing the learning system at main, detail functions. Lastly, management implications of these cyber education utilize are discussed in more detail.

Variable message signs (VMS) have the different sizes and a specific type according to the city scene and it has to be displayed by different message on the display panel in real-time. And VMS manufacturers must produce the different products in order to give a customized product to each order. In addition that, they should test and check the correct operation to each VMS product using the different message frame. That is very time and workers consuming and VMS emulator with an automatic variable message generator system is necessary. Also, the automatic message generator system is needed to real-time scheduling in order to display the message on the VMS panel like real world. In this paper, we design and implement the VMS emulator embedded the automatic message frame generator system with real-time scheduling which can set several parameters easily on the windows dialog.

The CRT monitor display system for SONAR signal that are commonly used in ships or naval vessels uses vector scanning method. Therefore the processing circuits of the system are complex. Also the purchase of parts is difficult as well as high-cost because the production had been shut down. FPGA-based embedded system is flexible to various digital applications because it can be able to simplify processing circuits and to make a easy customized design for end user, and it provides low-cost high-speed performance. In this paper, we describe an implementation of FPGA embedded system for real-time SONAR signal display using the triple buffering method to overcome some weakness of existing CRT system. Our system provides real-time acquisition and display capability of SONAR signal, and removes afterimage effect that is a critical problem of the system proposed in the preceding study.

An ICRF discharge cleaning and a fast wave electron heating experiment were performed. For automated operation and providing the diagnostics of the ICRF system, the ICRF local network was designed and implemented. This internal network provides monitoring, RF protection, remote control, and RF diagnostics. All the functions of the control system were realized by customized DSP units. The DSP units were tied by a local network in parallel. Owing to the distributed feature of the control system, the ICRF local control system is quite flexible to maintain. Developing the subsystem is a more effective approach compared to developing a large controller that governs the entire system. During the first experimental campaign of the KSTAR tokamak, the control system operated as expected without any major problems that would affect the tokamak operation. The transmitter was protected from harmful over-voltage events through reliable operation of the system.

Most of previous research on machining process planning has not fully included consideration on fixturing. With fixture components properly assembled with the part workpiece in a CAD modeling environment, necessary geometric information of fixture elements and their interrelations with the part model can be obtained so that machining process plans could incorporate fixturing considerations. This paper introduces an interactive fixturing system called I-Fix. I-Fix is a dowel-pin based modular fixture system, and it has been developed using Solid Edge CAD system and Visual Basic. Through customized operations of the assembly commands of the CAD system, I-Fix significantly simplifies user operations and thus reduces fixturing time. Furthermore, I-Fix enhances user convenience by providing general guidance about the fixture components and fixturing methods.
