This study has been conducted to identify the current status and practices of electrical stimulation for patients with dysphagia in Korea. Main goal of the study is to find evidences of developing and distributing a quality indicator and organized performance exam. This study analyzed 50 survey questionnaires given to clinical professionals in upper-scale general hospitals, university hospitals, nursing homes and professional rehabilitation hospitals. The survey sent out and collected by E-mails or interviews from August 21, 2013 to November 10, 2013. Most of the hospitals showed lack of using a quality indicator and organized performance exams in device maintenance, pre-operational tests and post-operational tests. It is strongly recommended to develop a standardized guideline of a higher quality indicator and organized performance exam in using neuromuscular electrical stimulator for patients who are suffering from dysphagia.

기존 등부표, 등명기 점검 시 사다리를 타고 상단에 올라가서 등명기를 점검하며, 너울성 파도 등으로 인하여 등부표가 기울어질 경우 추락사고가 발생할 수 있어 이를 예방하기 위해 엘리베이터 폴을 적용하여 등명기를 표체까지 하강시켜 안전하고 용이하게 점검할 수 있는 시스템 개발에 관한 것이다. 또한, 강철로 제작하는 표체를 탄소섬유로 제작하여 경량화하고 침추 무게, 투입 해상장비의 규모를 줄여 공사비를 절감하는 기대효과를 가질 수 있다.

Purpose: This paper proposes a performance evaluation method for state-of-the-art facility inspection/diagnostic equipment through a trend survey of equipment and standardization systems of US, Japan, and Korea. This paper also suggests the priority of developing a performance evaluation method through expert interviews and surveys. Method: In this study, report for the last 5 years of FMS, state-of-the-art equipment of facility maintenance companies/safety diagnosis specialist agencies and papers/research reports/patents of NTIS were analyzed to identify recent trends of facility inspection/diagnostic equipment usages. standardization system of US, Japan, and Korea were analyzed to figure out a suitable form of a performance evaluation method for the domestic situation. And expert interview and survey were conducted to identify the priority of developing a performance evaluation method. Result: The performance evaluation method must be developed by the shape that only evaluates performance, regardless of types of equipment, on inspection item level for creative technology development. The priority of developing the performance evaluation method was identified as crack detection of concrete for durability evaluation and displacement/deformation/fatigue detection of concrete and steel for stability evaluation. Conclusion: The performance evaluation method will be developed firstly for the crack detection of concrete for durability evaluation and displacement/deformation/fatigue detection of concrete/steel for stability evaluation. In order to promote creative technology development, the performance evaluation method should be developed in a form that provides standardized specimens or testbeds and can be applied regardless of types of technologies.

배전선로 정전고장 예방활동으로 순시/점검은 전력회사 기준에 따라 매년 시행하고 있다. 전력공급 장애 요소를 사전에 제거하거나 불량 기자재를 적출하여 정전을 예방하고 있다. 매년 수 천 건의 설비 불량개소를 개선하여 전력공급 품질 목표를 유지하고 있다. 설비가 방대하고 복잡, 다양해져 시간과 비용이 많이 소요되는 인력점검 보다 진단 장비 사용이 증가하고 있다. 설비운영방법에 있어서도 경년에 따른 교체보다 설비 노후도를 평가하여 교체하도록 하고 있어, 현장에서 설비의 상태 판단이 중요하다. 따라서 제한된 자원으로 최대의 효과를 얻기 위해 과학적인 장비를 이용한 진단방법이 도입되었으며, 본 연구에서는 국내 가공 배전선로 진단에 사용하고 있는 비접촉식 진단장비의 현장 적용시 검출특성과 상태 판정시 고려해야할 기술적 사항에 대한 결과 얻을 수 있었다.

A developer solves problems with isolating failures if faults are detected when inspecting missiles using the missile assembly test set (MATS) and then resumes the testing. In order to identify faults, it is necessary to analyze the data coming from the equipment, but the information received may not be sufficient, depending on the inspection environment. In this case, the developer repeats the test until the problem is reproduced or checks the performance of each piece of equipment that is related to the fault. When this task is added, schedule management becomes problematic, and development costs rise. To solve this problem, we need to design a MATS in a systematic way to increase fault coverage while satisfying the required reliability. By designing the necessary processes for each procedure, it is possible to reduce the fault identification time when a fault is detected during operations. But it is not possible to guarantee 100% fault coverage, so we provide another method by comparing costs and effects. This paper describes a development method to enhance the reliability of the missile assembly test set; it describes the expected effects when it is adapted, and describes the limitations of this method.

For the case of test equipments requiring data accuracy, real-time is highly required in acceptance test for performance evaluation of developed weapons. For convenience' sake, test equipments are usually developed using Windows. However Windows does not support real-time in itself. Thus, in this paper, so as to reduce development time and expenses, we design and implement an integrated middleware for real-time device drivers using RTiK-MP. Using DLL, we also support user API's for the sake of development convenience without details of the complex RTiK-MP structure. We evaluate the performance of the proposed integrated middleware using the RDTSC command which returns the number of CPU clock ticks. The evaluation results show that it operates correctly within error ranges in the periods of 1ms and 4ms for the cases of TCP/IP and RS-232, respectively.

The purpose of this paper is to examine the most recent tunnel scanning systems to obtain insights for the development of non-contact mobile inspection system. Tunnel scanning systems are mostly being developed by adapting two main technologies, namely laser scanning and image scanning systems. Laser scanning system has the advantage of accurately recreating the geometric characteristics of tunnel linings from point cloud. On the other hand, image scanning system employs computer vision to effortlessly identify damage, such as fine cracks and leaks on the tunnel lining surface. The analysis suggests that image scanning system is more suitable for detecting damage on tunnel linings. A camera-based tunnel scanning system under development should include components such as lighting, data storage, power supply, and image-capturing controller synchronized with vehicle speed.
