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.

A Smart TV device is either a television set with integrated internet capabilities or a set-top box for television that offers more advanced computing ability and connectivity than a contemporary basic television set. In recent years, there has been a popularity rose up on Smart TV (Smart Television) usage at home. This paper present the intelligent production status boards using features and functions of smart TV in shop floor. With the proposed status boards, we can reduce installation and operating costs of the existing production status boards. In addition, This article present the system that can line monitoring without equipments as CC TV.

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.

In this research a monitoring system for turning using NC information and the current of feed motor as a monitoring signal was developed. The overall system consists of modules such as learning process, NC data transmission, generation of forecast information, signal acquisition, monitoring and post process. In the learning process, the reference data and the cutting force equation necessary for monitoring are obtained from the accumulated monitoring results. In the generation of forecast information, the information of forecasted cutting forces is acquired from the cutting force equation and NC program and appended to each NC block as a monitor code. Reliability of monitoring is improved by using the monitor code in the real-time monitoring. Monitoring module is divided into two parts : the off-line monitoring where errors of NC program are checked and the on-line monitoring where the level of motor current is monitored during cutting operations. If the actual current level exceeds the limit value provided by the monitor code in the level monitoring, it is recognized as abnormal. In the event of abnormal status, the post processor sends the emergency stop signal to NC controller to stop the operation. Actual experiments have shown that the developed monitoring system works well.

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.

Boundary scan architecture test methodology was introduced to facilitate the testing of complex printed circuit board. The boundary scan architecture has a tremendous potential for real time monitoring of the operational status of a system without interference of normal system operation. In this paper, a new type of embedded controller for real time monitoring of the operational status of a system is proposed and designed by using boundary scan architecture. The proposed real time monitoring embedded controller consists of test access port controller and an embedded controller proposed real time monitoring embedded controller using boundary scan architecture can save the hard-wire resource and can easily interface with boundary scan architecture chip. Experimental results show that the real time monitoring using proposed embedded controller is more effective then the real time monitoring using host computer.

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.
