The increasing incidence of multiple primary carcinomas occuring in the upper aerodigestive tract is well documented, with the accepted incidence being as high as 20-30%. The fiberoptic endoscopy has also enabled visualization of areas previously inaccessible without general anesthesia. A prospective panendoscopic examination of the upper aerodigestive tract was peformed on 104 patients with squamous cell carcinoma of head & neck in our hospital between 1989 and 1994. Five second primary cancers (4.8% ：2 stomach, 2 esophagus, 1 lung cancers) were detected endoscopically. These finding should reinforce the belief that head & neck cancer is a panmucosal disease of the aerodigestive tract that silent second primary cancers are not uncommon. So every effort should be done to detect second primary cancers in head & neck squamous cell carcinomas. Panendoscopy has proved valuable in achieving that.

As nuclear industry in Korea is being expended, the number of user for radioisotope and radiation generators has being remarkably increased. As a result, radiation shielding problem for radiation safety has rasied as a question of great interest nowaday. In this report, gamma scanning test (GST), one of the nondestructive test methods of radiation shielding material was introduced and the review of the test method and its application were described. In addition for accurate evaluation of the test result, necessary basic equipments for the test and for improvement of the equipment were suggested. If the effective test method described above were widely and properly applied by GST related companies, the technology would be used effectively, as one of the safe nondestructive test for radiation shielding material in future.

Competency is an extended concept rather than knowledge and skill, which means the ability to efficiently and rationally solve various problems. This study focuses on the core competencies presented in the 2015 Revised Informatics Curriculum and aims to analyze the constitution method and composition of domestic and overseas Instruments that can measure core competencies. As a result of analyzing 12 Instruments developed by the countries and organizations, nine Instruments measure two or more competencies based on computing thinking, information culture literacy, and cooperative problem solving ability. Three Instruments have one competency were measured. Ten instruments were computer based tests, and 50% of the items were developed by two or more of multiple choice item, subjective item, and descriptive item. It is important to note that this study provided a crucial step in the development of Instruments to diagnose competencies to be developed into informatics science education.

This paper proposes a technological solution for improving the recognition direction of target objects for automatic vision inspection by machine vision. This paper proposes a technological solution for improving the recognition direction of target objects for automatic vision inspection by machine vision. This enables the automatic machine vision inspection to detect the image of the inspection object regardless of the position and orientation of the object, eliminating the need for a separate inspection jig and improving the automation level of the inspection process. This study develops the technology and method that can be applied to the wire harness manufacturing process as the inspection object and present the result of real system. The results of the system implementation was evaluated by the accredited institution. This includes successful measurement in the accuracy, detection recognition, reproducibility and positioning success rate, and achievement the goal in ten kinds of color discrimination ability, inspection time within one second and four automatic mode setting, etc.

Todays in the field of lens makers, the technology machinery equipment and investment is shrunken by many factors. But much more decisive investment is wanted to strengthen competitiveness. Most of all, the technology of management and quality examination is important in the confidence of lens. So external and internal examination must be accomplished scientifically not by macrography but by the microscope and the computer. As the hardness examination of glass in the automobile, that of spectacle lens must not be harmful to the human body. All the raw material of spectacle lens is being imported for the lack of technology. To overcome these circumstances. We must establish the research institute that can develop the technology and must train a technical expert.

문제: 영상의학과 특수 검사(CT, MRI, 초음파)가 고가인 것에 반해 환자의 대기시간이 길어 환자의 만족도가 낮고 부도율(non-attendance rate)도 높다. 목적: 환자의 영상의학과 특수 검사 예약률과 부도율(non-attendance rate)을 파악하고 이에 관한 원인을 분석하여 환자의 만족도를 증가시킬 방안을 모색하는 것이 목적이다. 의료기관: 경기도에 소재한 920병상규모의 대학병원 질 향상 활동: 영상의학과 검사 예약 환자의 부도율 원인 조사 및 만족도 조사를 실시하여 원인을 파악하고 개선을 통해 질 향상을 도모하였다. 개선효과: 전체부도율이 개선 전 9.6명에서 개선 후 7.1명으로, 불량률은 개선 전 10.43%에서 개선 후 7.81%로 다소 감소되었으며 검사 예약률은 개선 전 93.94%에서 개선 후 94.51%로 미 예약률은 6.0%에서 5.5%로 감소하였다.

현재 시중에 유통되고 있는 각종 상품에는 품질보증마크가 부착되어 있다. 이들 보증마크는 정부나 공신력을 갖춘 민간기관에서 시험검사를 한후에야 부착을 허락하기에 좋은 상품임을 믿고 고르는데 기준이 되고 있다. 많은 양의 외국산 물품이 수입되어 상점에서 쉽게 구입할 수 있게 된 요즘 국내외에서 이용되고 있는 각종 품질보증마크의 종류와 그 특성을 알아봄이 필요하겠다.
