VI probe, which is one of various in-situ plasma monitoring sensor, is frequently used for in-situ process monitoring in mass production environment. In this paper, we correlated the plasma etch results with VI probe data with the small amount of gas flow rate changes to propose usefulness of the VI probe in real-time process monitoring. Several different sized contact holes were employed for the etch experiment, and the etched profiles were measured by scanning electron microscope (SEM). Although the shape of etched hole did not show satisfactory relationship with VI probe data, the chamber status changed along the incremental/decremental modification of the amount of gas flow was successfully observed in terms of impedance monitoring.

VR (Virtual reality) technologies have given engineers the ability to design, test, and evaluate engineering systems in a virtual environment. The virtual plant is the highlight of the application of the VR technology to plant engineering. Plant design, maintenance, control, management, operation are integrated in the virtual plant. The VR monitoring system including the concept of the virtual plant is developed to replace a current control room that has number of gages and warning lamps in two-dimensional panels which shows the operating status of a plant. The operating status of the plant is displayed in the VR monitoring system through the realistic computer graphics. Sophisticated, realistic and prompt control becomes possible. The VR monitoring system consists of advanced visualization, walk-through simulation and navigation. In the virtual environment, a user can navigate and interact with each component of a plant. In addition, the user can access the information by just clicking interesting component. The VR monitoring system is operated with various modules, such as (1) virtual plant constructed with Graphic Management System (GMS), (2) Touch & Tell System, and (3) Equipment DB System of Part. In order to confirm the usefulness of the VR monitoring system, a pilot gas plant which is currently being used for plant operator training is taken as application. The end of the paper gives an outlook on the future work and a brief conclusion.

In this paper, we suggest an activity and health monitoring system to observe the status of the dogs in real time. We also propose a k-days algorithm which helps monitoring pet health status using classified activity data from a machine learning approach. One of the best machine learning algorithm is used for the classification activity of dogs. Dog health status is acquired by comparing current activity calculation with passed k-days activities average. It is considered as a good, warning and bad health status for differences between current and k-days summarized moving average (SMA) > 30, SMA between 30 and 50, and SMA < 50, respectively.

본 연구에서는 이송축 직류 서보 모터의 전류신호와 NC정보를 이용해서 선삭 가공상태를 감시하는 시스템을 개발하였다. 모터 전류는 가공 부하의 상태를 잘 나 타내며, NC 장치에 내장되어 있기 때문에 신호 검출을 위한 별도의 센서가 필요 없어 서 공구가 수시로 바뀌는 NC작업 감시를 위한 유효한 신호이다. 또 NC 정보로부터 작업을 예측함으로써 감시 대상을 명확히 하고 신뢰성을 높이고자 하였다. 전체적인 감시 시스템의 프로그래밍 언어로는 C를 사용하여, 실시간 감시처리를 가능하게 하였 다.

The hinge joint is the key to the overall cooperative working performance of the assembled beam bridge, and it is also the weakest part during the service period. This paper proposes a method for monitoring and evaluating the lateral cooperative working performance of fabricated beam bridges based on dynamic strain correlation coefficient indicator. This method is suitable for monitoring and evaluation of hinge joints status between prefabricated girders and overall cooperative working performance of bridge, without interruption of traffic and easy implementation. The remote cloud monitoring and diagnosis system was designed and implemented on a real assembled beam bridge. The algorithms of data preprocessing, online indicator extraction and status diagnosis were given, and the corresponding software platform and scientific computing environment for cloud operation were developed. Through the analysis of real bridge monitoring data, the effectiveness and accuracy of the method are proved and it can be used in the health monitoring system of such bridges.

경계 주사 구조(Boundary Scan Architecture)기 법은 복잡한 인쇄 회로 기판(PCB : Printed Circuit Board)을 테스트하기 위해 도입되었다. 이러한 경계 주사 구조는 시스템의 정상 동작에 간섭을 주지 않고 시스템의 동작 상태를 실시간 모니터링 하는데 대단한 잠재력을 지니고 있다. 본 논문에서는 경계 주사 구조를 이용하여 시스템의 작동 상태를 실시간으로 모니터 하기 위한 새로운 실장 제어기를 제안하고 설계한다. 제안된 실시간 모니터링 실장 제어기는 경계 주사 구조의 경계 주사 셀 제어기(Test Access Port Controller)와 범용 실장 제어기(Embedded Controller)로 구성되어 있다. 제안된 경계 주사 구조를 이용한 실시간 모니터링 실장제어기는 하드와이어의 자원을 절약해 주고 경계 주사 구조를 지니고 있는 칩에 쉽게 인터페이스 된다. 실험 결과는 제안된 실장제어 기가 시스템의 동작 상태를 실시간 모니터 하는데 호스트 컴퓨터에 의한 모니터 링에 비해 효과적임을 보여준다.

Objective : This study aimed to investigate the current status of intracranial pressure (ICP) monitoring in patients with severe traumatic brain injury (sTBI) in Korea and the association between ICP monitoring and prognosis. In addition, a survey was administered to Korean neurosurgeons to investigate the perception of ICP monitoring in patients with sTBI. Methods : This study used data from the second Korea Neurotrauma Databank. Among the enrolled patients with sTBI, the following available clinical data were analyzed in 912 patients : Glasgow coma scale score on admission, ICP monitoring, mortality, and extended Glasgow outcome scale score at 6 months. In addition, we administered a survey, entitled "current status and perception of ICP monitoring in Korean patients with sTBI" to 399 neurosurgeons who were interested in traumatic brain injury. Results : Among the 912 patients, 79 patients (8.7%) underwent ICP monitoring. The mortality and favorable outcome were compared between the groups with and without ICP monitoring, and no statistically significant results were found. Regarding the survey, there were 61 respondents. Among them, 70.4% of neurosurgeons responded negatively to performing ICP monitoring after craniectomy/craniotomy, while 96.7% of neurosurgeons responded negatively to performing ICP monitoring when craniectomy/craniotomy was not conducted. The reasons why ICP monitoring was not performed were investigated, and most respondents answered that there were no actual guidelines or experiences with post-operative ICP monitoring for craniectomy/craniotomy. However, in cases wherein craniectomy/craniotomy was not performed, most respondents answered that ICP monitoring was not helpful, as other signs were comparatively more important. Conclusion : The proportion of performing ICP monitoring in patients with sTBI was low in Korea. The outcome and mortality were compared between the patient groups with and without ICP monitoring, and no statistically significant differences were noted in prognosis between these groups. Further, the survey showed that ICP monitoring in patients with sTBI was somewhat negatively recognized in Korea.
