In this study, the performance of a DPRMs is evaluated and the measurement precision for the pile driving is presented. The DPRMs is a visual-measurement system for the pile rebound and the penetration movement using a high speed line-scan camera. The DPRMs generates the measurement deviation. It is caused by the strong impact for the pile driving. To reduce it, the vibration signal analysis about the pile driving is performed. As a result, it is confirmed that the tilting frequency of a camera-tripod structure corresponding to excitation frequency range of the ground is under 40Hz. Through the structure modification, the camera-tripod structure is redesigned to the model being free itself from the excitation frequency range of the ground. By the verification testing about the improvement effects, it is inspected that the tilting and measurement deviation of the redesigned DPRMs are reduced.

Early generations of products had little to no inherent capability to test themselves. The technologies involved often required only visual inspection and limited probing to troubleshoot the system once it was turned over to maintenance personnel. However, as the complexity of military and commercial systems grew, symptoms of failure became less noticeable to the operator. Therefore, the procedure to access, inspect, repair and replace a component became complicated, the requirements for personnel skill and testing equipment increased. and it took too long of a time to maintain a system. Meanwhile, the need for availability became more mission-critical and maintenance become very expensive. The obvious solution was to design in-system circuits or devices to self-test the primary system, the Built-In-Test(BIT) was born. This approach has continued right on up through present systems and is an integral part of systems now being designed. The object of this paper is to present a state-of-the-art research for filtering out the BIT diagnosis mistakes using Bayesian analysis and develop the algorithm for Redundant systems with BIT to improve BIT diagnosis.

Purpose: The purpose of the study was to examine the effects of multisensory stimulation (MSS) using familiarity on persons with dementia (PWDs) residing in nursing homes in Korea. Methods: A nonequivalent control group with pre and posttests was used. Fifty one PWDs were included if they: 1) were over 65 yr old, 2) were diagnosed with dementia, 3) had no visual or speech impairments, 4) were able to communicate, and 5) had spent more than one month in a nursing home. The experimental group (n=25) received a 55 min MSS program twice a week for 10 weeks. The outcome variables included were cognition, activities of daily living, grip strength, depression, wandering, and aggressive behaviors. Repeated ANOVA was used for data analysis. Results: There were no significant differences in demographics or the main variables at pretest. Cognition, depression, wandering, and aggressive behaviors were significant over time between the two groups. Grip strength was only significant when accounting for interaction between group and time. Conclusion: An intervention of MSS using familiarity was marginally effective in improving cognition, depression, wandering, and aggression. Future study is suggested with a larger sample and longer treatment to retest the effects of MSS.

Unlike the electric method capable of checking only product defect, the real time optical metrology is suggested for measuring and visualizing vibration with respect to position of surface acoustic wave in RF device. The measuring limits and conditions for surface acoustic wave is given, and the interference and diffraction due to RF signal are analyzed by optical interpretation. A single mode laser and a 105MHz-center-frequency repeater filter were employed for experiments and theoretical analysis. In this paper, the optical metrology providing visual energy distribution and real time inspection for surface acoustic wave is proposed for development of high quality multi-service and multi-frequency RF module.

This study was conducted to find out the paternal attachment to neonate, and to identify factors affecting paternal attachment. The purpose was to make the base data for nursing intervention to improve paternal attachment. The subjects of this study were 93 fathers whose partners have delivered normal neonate in 1 hospital in Busan. Data were collected from Sep. 1th to Oct. 31th 2005 by a self-report questionnaire. The instrument for this study was based on 7 kinds of characteristics of paternal attachment by Greenberg & Morris(1974), and modified by researchers. The statistical methods for data analysis were percentage, mean, standard deviation, t-test, ANOVA with SPSS program Ver 10. The conclusions are as follows. Fathers had the high degree of paternal attachment to neonate. But, there were not significant correlations between paternal attachment and the father's demographic characteristics, pregnancy plan, delivery pattern, delivery order, sex of neonate and past experience. Also there were not significant correlations between paternal attachment and early visual contact frequency of father-neonate. Further research about factors affecting paternal attachment to neonate and high risk neonate as well as low birth weight neonate is required.

This paper deals with inspect algorithm using visual system. One of the major problems that arise during polymer production is the estimation of the noise of the color product.(bad pallets) An erroneous output can cause a lot of losses (production and financial losses). Therefore new methods for real-time inspection of the noise are demanded. For this reason, we have presented a development of vision system algorithm for the defect inspection of PE color pallets. First of all, in order to detect the edge of object, the differential filter is used. And we apply to the labelling algorithm for feature extraction. This algorithm is designed for the defect inspection of pallets. The labelling algorithm permits to separate all of the connected components appearing on the pallets. Labelling the connected regions of a image is a fundamental computation in image analysis and machine vision, with a large number of application. Also, we suggested vision processing program in window environment. Simulations and experimental results demonstrate the performance of the proposal algorithm.
