In complex industrial world, many companies make every effort to analyze their competition capability through various performance evaluation tools to cope with rapidly changing business environment. Among evaluation tools the balanced scorecard (BSC), put forward by Kaplan and Norton in 1992, is a strategic performance management tool for measuring whether the smaller-scale operational activities of a company are aligned with its larger-scale objectives in terms of vision and strategy. The BSC tool offers a comparative advantage over others to evaluate the objective achievement of a company by linking its strategic objectives with operational KPI. In this paper, we introduce a case that the BSC performance evaluation system was implemented based on product data management and applied it to the business process. Specially, we shows a implementation procedure to derive discipline-specific topics and key performance metrics.

A construction process consists of value adding activities and non-value adding activities, necessary or unnecessary. If construction personnel can eliminate inefficient and/or unnecessary activities within the process, they may have a great opportunity to improve their construction process. The Product Process Analysis (PPA) technique, which was developed in the manufacturing industry, can be applied for identifying wastes in the construction process and ultimately improving the process itself. It provides useful tools, such as a process chart worksheet and flow diagram, for mapping the flow of construction activities with predetermined standardized symbols. These tools make people understand the flow of activities more easily, identify value adding/non-value adding activities within the process, and areas where the process can be improved. The example applications of PPA are demonstrated in the paper through the case studies implemented on the construction process of structural steel. The results of case studies indicate that PPA technique was effective at identifying and removing wastes in the steel construction process. It is also found that PPA technique is more effective for improving highly repetitive construction processes.

Recently, it has been widely conceived that Concurrent Enginering (CE) can provide a competitive edge for companies that have confronted with rapidly changing market requirements, such as shortening of product life-cycles, high quality and low cost products, diversity of customer demand, and so on. CE is generally recognized as a practice to bridge the gap between designing a product and other various life-cycle activities, such as manufacturing, assembly, testing, and maintenance, at an early stage of design. In this paper the concepts of CE is first overviewed, and many of its supporting tools are discussed. It is then proposed an architecture of a CE support system that can provide a unifying view of the tools. Finally, a case that has successfully implemented the concepts is presented.

최근 빠르게 변화하는 디지털 디자인 분야에 발맞추어 그래픽 저작도구도 다양한 형태로 발전되어 왔다. 그러나 사용자의 환경에 따라 형태와 크기가 달라지는 인터페이스 디자인 분야에서는 보다 유기적이고 확장 가능한 저작도구를 필요로 하게 되었고, 다양한 신규 도구의 등장과 함께 업무 환경에도 변화가 나타나고 있다. 따라서 본 연구는 현재 국내 디자이너들이 주로 사용하고 있는 그래픽 저작도구의 현황을 파악하고 이를 해외 사례에 비교하여 봄으로써 국내 시장과 해외 시장의 그래픽 저작도구 환경 및 디자이너가 저작도구를 선택하는 기준과 기업 유형 및 참여하고 있는 프로젝트의 유형에 따라 저작도구의 선택이 어떻게 달라지는지를 알아보았다. 연구결과 저작도구의 선택은 프로젝트의 유형과 효율성에 따라 달라졌는데 이를 토대로 디자이너 개인과 기업이 그래픽 저작도구를 선택하고 업무 환경을 구축할 때 참고가 될 수 있는 자료를 제시하고 향후 그래픽 저작도구가 발전해 나가야 할 방향을 제안하고자 한다.

본 연구는 성인 문해력 조사연구의 국제 동향을 분석하여 우리나라 성인 문해력 조사 도구 개발 및 문해교육 정책의 시사점을 얻기 위한 것이다. 이를 위하여, 국제 표준화 조사도구와 별도로 독자적인 성인 문해력 조사 도구를 개발하여 활용하고 있는 영국, 프랑스, 독일의 성인 문해력 조사 방법을 비교 분석 하였다. 분석 결과, 세 국가는 성인 문해교육 정책의 연계성 속에서 생활문해 또는 기능문해의 관점에서 문해의 의미를 정의 내리고 있었으며, 읽기와 쓰기를 중심으로 수리력과 정보 활용 능력도 측정하고 있었다. 문해력 수준의 판정은 각 국가별 상황을 고려하여 다양하게 이루어지고 있었으며 조사의 정책 연계성과 효율성을 강조하는 SQC모델을 채택하고 있었다. 이런 분석 결과를 통해 우리나라 성인 문해력 조사를 실시함에 있어 성인 문해교육 정책의 실행과 조사 주체의 일원화, 일상생활을 반영한 조사도구의 개발, 수준별 문해력 측정, 조사도구의 모듈화, 조사의 경제성과 활용성의 확보 등의 시사점을 얻을 수 있었다.

$21^{st}$ century has seen a tremendous advancement in the field of Information and Communication Technology. The commercial utilization of Internet tools and technologies has brought change in the traditional working environment. The functioning in an electronic environment is far more complicated than working in traditional environment and this brings many challenges, threats and potential problems. In this paper we analyze the challenges, threats and potential problems in the working environment of Pokhara University due to application of Internet tools and technology. We have chosen four basic areas on the basis of use that include web resources, electronic mails, social sites and P2P technologies. The main focus is to analyze the impact on work place productivity, social interaction, use and abuse of technology and legal issues associated with them. We, finally summarize the findings and offer solutions and recommendations from the observed data based on direct survey conducted in Pokhara University, Nepal.

In vibro-acoustic analysis, the commercial CAE tools, such as SYSNOISE, is usually used to take into account of the coupled effects of fluid acoustics and structural vibration. The acoustic field can be solved by either FEM or BEM, while the vibration field is usually solved by FEM. The interior or exterior acoustic problems with the coupled effects of the structural boundary could be solved by the commercial tools. The commercial tools, however, could not solve the problems in case that both the interior and exterior acoustic field is coupled with the structural boundary. In this paper, a realistic method based on FEM/BEM coupling scheme is presented to analyze the acoustic radiation from the internal source in a chamber to external acoustic field through elastic structural boundary. Several numerical examples are implemented to validate the developed program.

In order to achieve high precision machine tools, the research for performance enhancement of feed drive systems is required. Development of the high speed feed drive system has been a major issue for the past few decades in machine tool indestries. Because table levitation system decrease the table weight, an effect of reaction by weight is minimized and lost motion can be removed at maximum. In case fled system is designed with drive motor, ball screw and support bearing load capacity selection, an effect of decrease of the table weight exist. So, the table weight through an effect of decrease call it into the realization of cost down. Stick-slip friction has a great influence on the contouring accuracy of CNC machine tools. In this paper table levitation system has been developed for the stick-slip in a fled drive systems.

This paper presents a software design simulation method for controlling multiple mechanism carrier system (MMCS), which is mainly used in a wrapping machine or a case packing machine. This method uses a mechanical tool-work interactive model proposed in this paper, in order to represent the interactive behaviors between some tools and a work driven by their tools, in which low effect states of a work are defined. Based on this method, a 3-D simulation system has been built. It consists of shape modeling of each device, behavior definitions of tools, and control logic using if-then expression. By applying it to a ase packing machine having about 30 mechanical devices and 100 inputs/outputs for control, the effectiveness of this method has been shown in general verification of control logic specification in an early software design phase and the possibility of smooth communication tool between mechanical and software designers.

In the present study, the middle school students' perception on the environment course was surveyed before and after three different lessons. It was found that most students were taking environment related issues mainly from mass media including internet and broadcasting. The young students were satisfied at practical experiments, but at the same time a few old fashioned experimental programs would not be preferred. Utilization of multimedia such as audio-visual tools was one of the effective tools for the environment class, because it could help to understand even the profound principles of the chemical and physical processes. However, some students did not concentrate on the display, causing frequent disturbance of the class. Since the school for this investigation did not choose the environment as a selective course, practical tools and materials for the experiment should not be sufficient, and thereby a further detailed work must be followed with the students who are taking environment lessons.
