  • The purpose of this study is to define the role of a T. Q. C. engineer in the plant engineering activities. A "plant engineering" moves to complete a new project through a series of stages such as: 1. Research & Development stage. 2. Economic evaluation & engineering design stage. 3. Erection & start up stage. 4. Final production & control stage. This suggests that the plant engineering project should be carried out with a wide variety of tasks, as well as a central control. For a successful completion of the project, a T. Q. C. engineer is required, in practice, either as a central activity creator or as a key advisor in each task.

  • As a matter of fact, the better architecture is very important things to create our generation and culture. Also, construction quality improvement is critical necessary to keep the culture and international competition which must be obtained through the consciousness reform of persons concerned. Therefore, the purpose of this proposal is to provide the basic point for establishing a practical compaign against construction failures. In this year, we have to remember the facts that's faced on market opening in construction market which is agreed in WTO. The contents of subject are as follows : 1 ) Subconscious reform of technician and projector concerned 2) Responsable consciousness of original contractor 3) Workmanship of skilled labor 4) Reasonable budget and bidding included sub-contractor 5) Advanced design and engineering quality 6) Certification of consulting engineer

  • Grading and sorting an indeterminate form of agricultural products such as sweet potatoes and potatoes are a labor intensive job because its shape and size are various and complicate. It costs a great deal to sort sweet potato in an indeterminate forms. There is a great need for an automatic grader fur the potatoes. Machine vision is the promising solution for this purpose. The optical indices for qualifying weight and appearance quality such as shape, color, defects, etc. were obtained and an on-line sorting system was developed. The results are summarized as follows. Sorting system combined with an on-line inspection device was composed of 5 sections, human inspection, feeding, illumination chamber, image processing & control, and grading & discharging. The algorithms to compute geometrical parameters related to the external guality were developed and implemented for sorting the deformed sweet potatoes. Grading accuracy by image processing was $96.4\%$ and the processing capacity was 10,800 pieces per hour.

  • 국내에서 시공되는 콘크리트 구조물의 대부분은 레미콘(ready-mixed concrete)으로 시공되고 있기 때문에 레미콘의 품질관리(quality control) 및 품질확보(quality security)는 곧 콘크리트 구조물의 품질과 내구성의 확보를 위해 매우 중요한 사항이다. 최근 콘크리트 구조물의 잦은 사고로 인해 콘크리트의 품질문제가 사회문제로 나타나고 있으며 이에 대비한 콘크리트 품질보증 시스템의 확립이 시급한 실정이다. 그러나 레미콘의 품질환경은 원재료의 품질저하, 레미콘 운반시간의 증대 및 기술개발의 미흡 등 주변여건이 좋은 편은 아니며 레미콘 산업도 경쟁시대에 돌입하면서 레미콘 품질이나 기술우위의 시대로 변화되고 있다.(중략)

  • Sampling In this study, we examined the problems and their improvement plans associated with the reliability management sector in quality management engineer test conducted in Korea. First of all, there seems to be a problem in that the terminology is not unified and some techniques essential for reliability analysis are not included. We also looked at quality and reliability tests performed in foreign countries (especially USA) that Koreans often acquire. In particular, it can be seen that the CRE test almost overlaps with the contents of the reliability management engineer test in Korea. However, while the USA is an open book test, Korea is not, so the problem is that there are too many formulas to memorize on the part of the test takers. In addition, the analysis of the data is done manually without using computer software. If the test were an open book test like the CRE test in USA, it will be a test that can go beyond fragmentary knowledge and check whether test takers have the essential elements in reliability management. Lastly, if we adopt re-certification system through education and work within a certain period of time, as in USA, it will be a qualification test suitable for modern people living in a flood of information.

  • Ensuring the quality of molds is one of the major issues in mass production. In general, securing the quality of the molds is achieved by repeating grinding and die spotting after machining the molds based on engineer's decision. However, this heuristic method is affected by the engineer's skill and working environment. Therefore, a lot of time and resources are needed in order to ensure quality. In this study, ensuring the quality of molds using grinding map which is generated using automatic measurement is proposed. An automatic measuring system based on CMM (Coordinate Measuring Machine) is developed for measuring the molds. This system generates the measurement path automatically using the 3D CAD model of products. CAD (ComputerAided-Design), CAM (Computer-Aided-Manufacturing), and CAQ (Computer-Aided-Quality) technology is integrated using DMIS (Dimensional Measuring Interface Standard) format in the automatic measuring system. After measuring the molds, a grinding map is generated using the gap between the CAD model and measured values of mold. The grinding map displays the machining tendency and the required amount of grinding with values on a 3D map. Therefore, the quality of molds can be ensured with exactness and quickness based on the grinding map. This study shows that integrating the planning, measuring, and analyzing based on computer technology can solve the problem of quality assurance of mold using the proposed method, therefore the productivity can be increased.
