Nanometer positioning control with high velocity and long stroke is discussed. A one-axis stage mechanism driven by an AC linear motor and guided by a rolling ball guide has been constructed. Coarse and fine position controls are designed by using nonlinear dynamics of the rolling guide. Switching from coarse positioning to fine positioning is studied.

We have been taught designing process throughout the long period of education. Nevertheless it is hard to make a quick response to actual project However if we are faced with the actual project as a design professionals it is hard to cope with the project at once nothing but ambiguous idea. Also most of designers concemed with the project do not recognize who are responsible for what. Consequently this attitude delays the entire operation causing waste of time and resources and leads to the unacceptable result. This research is designed therefore to come up with the projects control process that is practical enough to encourage interior designers as well as design firms to face actual projects with shrewd response. There is of course no single right answer to certain design projects. But at least there should be a guideline which shows designers more reasonale systematic ways to control design project lest they should waste time and cost : a guideline as an assistance for successful design result.

This paper presents the case study of the CE by collaborative system and proposes a model of the CM group for the cable supported bridge. The cable supported bridges have a large project scale and need a high level of construction method. Therefore an advanced construction management system is required for successful completion of project. The construction management (CM) group which control design management, construction plan, subcontract, technical support and R&D is organized for the cable supported bridge project. The CM group established a collaborative system with construction site and drew an effective management of cost, process, quality, safety for each project. Furthermore, the CM group established the procedure of construction management based on the construction engineering (CE) items and performed the project management on the construction phase. Efficiency of cost reduction and site control is maximized by using a collaborative system.

Client organization inadequate project planning before awarding the contract and insufficient monitoring and control system among the parties involved create severe problems. Ultimately, large-scale projects go beyond the expected cost and time control limits. This paper discusses the major issues involved with a large-scale Hydropower Project in Pakistan Public Sector environment. The latest approved Baseline Plan of project was reviewed and analyzed using Variance Analysis and Trend Analysis techniques in Primavera project management software to assess the efforts made of the parties involved. It was found that Project is 202% Cost overrun and 25% time delays from original contract award. After analysis of baseline plan and quantification of various variance issues in impacted activities, the questionnaire survey was conducted to identify the impact of causative factors. There were almost 17 most significant causative factors identified among 60 identified factors and responsibilities are assigned accordingly. At the end recommendations are made for strategic decisions as lessons learned during project evaluation.

The Multi-family Residential is one of the most famous building types for a rental property in the US. Often times it includes multiple residential buildings and some amenity facilities, including a clubhouse or leasing office, swimming pool, dog park, and garages. Since the building type is built for rental purposes, the construction planning is phased and it makes the project complicated. Detailed planning and execution are important for successful construction management. This paper provides some management practices that are applied to one of the multi-family residential construction projects in Phoenix, AZ. The Front End Planning (FEP) process performed by both owner and contractor is the first key to a successful construction project. Specifically, the early review of phased turnover strategy, grading, fire/Americans with Disabilities Act (ADA) compliance, and Mechanical/ Electricity/Plumbing/Technology (MEPT) will provide absolute benefit to the project. Second, using a scheduling method to control short-term schedules and long-term can provide the ability to manage the issues with agility. Third, material delivery and procurement dominate the both project schedule and cost. With this COVID-19 circumstance, it is hard to expect the material, equipment, and labor forces to be delivered on time with the contracted price. Managing floats are more than important to managing construction productivity. Risk management should work to share the risks fairly. Lastly, turnover is directly linked with the profit of the project for both owner and contractor. The communication between the owner and contractor to re-schedule the proper turnover schedule is important for the phased construction project.

Instrumentation and Control (I&C) of the Neutral Beam Test Stand (NB- TS) Facility at the Korea Atomic Energy Research Institute (KAERI) for the Korea Superconducting Tokamak Advanced Research (KSTAR) project has been underway since the start of the project to answer the diverse requests arising from the various facets of the development and construction phases of the project. Optical signal transmission constitutes a significant portion of I&C works and has been performed for the entirety of the project. During the NB- TS construction and related experiments, significant achievements to a more accurate as well as more refined optical signal transmissions have been made. Examples of those I&C works that utilized the optical signal transmission are the Langmuir probe signal transmission, gradient grid current signal transmission, gas flow control and signal transmission, ion source temperature measurement, beam line component temperature monitoring, and coolant flow signal transmission, etc. These optical signal transition provisions are now performing part of the indispensable functions for the proper operation of the NB- TS facility. Attained experience and expertise are expected to be well applied to the upcoming main neutral beam injection (NBI) system construction for the KSTAR project.

Railway signaling systems consist of several vital computerized equipment such as CTC(Centralized Traffic Control), EIS(Electronic Interlocking System), ATC(Automatic Train Control) and so on. Currently, the project for development of railway signaling systems for the next-generation high-speed train is progressed according to the G7 project and railway signaling related several companies and research institute are joined this project consortium. The railway signaling systems, being developed in this project, called as a kTCS(Korean Train Control System), is composed of kTCS-CTC, kTCS-IXL, kTCS-ATC and etc. kTCS signaling systems have to be operated at the laboratory testing level as integrated signaling systems by interface between each railway signaling systems before railway field installation and revenue service. To solve this matter, communication protocols between each signaling equipment are designed and message codes for each defined protocols have defined. And also several equipment has developed for the railway integrated signaling systems for laboratory testing. We has plentifully tested and verified the designed protocols and the characteristics of integrated railway signaling systems with our developed each kTCS signaling equipment and communication protocols. In this paper, the integrated kTCS system including communication protocols is presented.

컴퓨터 및 통신 기술의 혁신으로 IT는 이제 기업에서 이루어지고 있는 업무의 효율성 제고뿐 아니라 새로운 비즈니스 기회 제공의 역할까지 하고 있다. 그로 인하여 기업은 IT 프로젝트를 추진하게 되는 경우가 많아졌는데, 이에 따라 IT에 대한 투자 규모도 점차 커지게 되면서 구축 결과에 대하 관심이 모아지고 있지만 실질적으로 실패하는 경우가 많다. 이에 따라 IT 프로젝트를 수행하는 주체인 PMO가 수행하는 프로젝트 거버넌스의 역할들이 프로젝트 성과로 나타나는 효과를 알아보고 프로젝트 수행 중 일어날 수 있는 여러 가지 문제점에 대한 해결을 위하여 프로젝트 거버넌스의 어떠한 역할이 부각되어야 하는지에 대한 연구를 수행하였다. 실증분석 결과 본 연구에서 제시된 프로젝트 거버넌스의 역할들 즉 연결고리 역할, 조정 역할, 통제 역할, 전략적 방향제시 역할, 지원 역할, 사회융화 역할이 모두 프로젝트 성과 향상에 큰 역할을 하는 것을 볼 수 있었고, 특히 프로젝트 도중 생길 수 있는 문제점에 대한 해결을 위하여 갑의 PMO에 대한 통제, 갑의 기업문화 및 환경에 대한 PMO의 명확한 이해가 필수적인 것으로 드러났다. IT프로젝트의 성공을 위해서는 이러한 프로젝트 거버넌스의 역할들을 적극 활용하여야 하며 프로젝트 도중 발생할 수 있는 문제점 해결을 위해서는 통제 및 사회음화 역할을 수정 및 보완하여 활용하여야 할 것이다.
