    Title: Categorizing accident sequences in the external radiotherapy for risk analysis
    Author: Kim, Jonghyun
    Subject: Accident ; Radiotherapy ; Risk Assessment ; Safety
    Description: This study identifies accident sequences from the past accidents in order to help the risk analysis application to the external radiotherapy. This study reviews 59 accidental cases in two retrospective safety analyses that have collected the incidents in the external radiotherapy extensively. Two accident analysis reports that accumulated past incidents are investigated to identify accident sequences including initiating events, failure of safety measures, and consequences. This study classifies the accidents by the treatments stages and sources of errors for initiating events, types of failures in the safety measures, and types of undesirable consequences and the number of affected patients. Then, the accident sequences are grouped into several categories on the basis of similarity of progression. As a result, these cases can be categorized into 14 groups of accident sequence. The result indicates that risk analysis needs to pay attention to not only the planning stage, but also the calibration stage that is committed prior to the main treatment process. It also shows that human error is the largest contributor to initiating events as well as to the failure of safety measures. This study also illustrates an event tree analysis for an accident sequence initiated in the calibration. This study is expected to provide sights into the accident sequences for the prospective risk analysis through the review of experiences.

    Title: Design and fabrication of implantable pressure sensing resistor sensor for human bladder monitoring system
    Author: Kim, Jonghyun; Choi, Bumkyoo
    Description: Many aging people and patients have difficulties in bladder control. Recent methods have been studied for non-invasive measuring for bladder information. It must be improved to a more convenient and real time measurable system for accurately analyzing and controlling individual bladder information. This paper presents the pressure sensor for the invasive bladder monitoring system. The system has the pressure sensing resistor sensor (PSRS) which is set-up inside the bladder. The PSRS consists of a flexible and contactable diaphragm which deforms towards an underlying substrate while a range of pressure is applied. The flexible diaphragm has a thin metal film which acts as a switch and the underlying substrate has interdigitated electrodes which serve as a variable resistor. The PSRS initially exhibits infinite electrical resistance with no external pressure applied since the metal switch is not contact with the interdigitated electrodes. As the applied pressure increases above a threshold, the contact area increases thus the resistance of the PSRS decreases. Based on the finite element analysis, proper ranges for the diaphragm size and gap distance are determined. The sensor, the diaphragm size of which is 2.6 × 2.6 mm 2 , has been fabricated through MEMS technology. The change of the electrical resistance is 0.5 Ω for the range of human bladder pressure (0–10 kPa). This PSRS will be effectively used for reliability and stability of the research for the improvement of bladder management. It can also be utilized for the future application.

    Title: Investigation of surface uniformity machined by ceramic brush
    Author: Kim, Youyoung; Kim, Jonghyun; Lee, Sun-Kyu
    Subject: Lapping process ; Ceramic brush ; Surface finishing ; Preload ; Protrusion ; Surface uniformity
    Description: This paper investigates the issue of unevenness of machined surface using ceramic brush for aiming the automatic lapping of the large work surface. A numerical model and machining results with ceramic brush are presented. In the machined surface, the slight sloped surfaces between left and right sides along the feed direction were generated, and they were highly affected by the protrusion of fiber, the preload, the feed rate, and the overlapped machining. The numerical model for ceramic brush lapping is induced based on trajectory simulation of each brush fiber using the dynamic FEA result of contact pressure and deformation to understand the issues of surface uniformity. In the simulation part, A FEA model of brush lapping is proposed to investigate not only its elastic behavior during the machining process but also its effect on the machined surface. The lapping experiment is comprised of several steps using different preload, revolution speed, protrusion, feed rate, and overlapped machining pitch. For each step, it is shown that the trend of change in surface quality according to each machining parameter using the numerically controlled machine. Each machining condition plays an important role in lapping quality, which can determine the surface uniformity. Highly smooth surfaces were obtained by selecting the appropriate conditions without any unevenness issues on overlapped machining region. Also, the surface roughness comparison result with other surface finishing method presents similar quality even in worse initial surface roughness condition, which indicates the possibility of efficient automatic surface uniformity using ceramic brush lapping on milling surface of workpiece.
