This study was conducted to examine the relationship among the error risk of high-alert medication, attitudes to single-person checking of medication, and medication safety activities. The participants were 60 nurses working in the intensive care unit. Data were analyzed using descriptive analysis, t-test, analysis of variance, and Pearson's correlation coefficient. The mean scores of the knowledge and certainty of high-alert medication were $0.71{\pm}0.11$ and $2.74{\pm}0.59$, respectively. The mean score of the error risk of high-alert medication was $1.63{\pm}0.24$ and that of attitudes to single checking medication was $3.32{\pm}0.49$. The error risk of high-alert medication had a positive correlation with nurses' attitudes to single checking medication (r = .258, p = .047), which is correlated with the scores for certainty of knowledge (r = .284, p = .028). Based on the results of this study, continuing education for high-alert medication and the development of an accurate protocol for single checking medication are needed to improve the stability of high-alert medication.

In machining screws which are important members in mono pumps or progressive cavity pumps CNC turning center with 3 axes is usually used. This sort of screw machining requires large amount of CL data points and rotational tools are used in machining. When working out the CL data points consideration of possible tool interference is important in order to avoid undercut. This paper describes the checking methods of tool interference in the screw machining on the CNC turning center. First of all a specific shape of a screw cross-section that could commonly be applied to all screws was chosen and then possible tool interference associated with that shape was identified. Checking method was mathematically developed and verified. This checking method will be utilized in the CAM system developed by the authors for screw machining on the 3-axis CNC turning center.

Design works consist of essential works and subsidiary works. Essential design works means designing creative ideas and productive ideas, while subsidiary design works means helping essential works those are making data tables and specification sheets, checking CAD data's integrity. Subsidiary design works forms the bulk of the whole design process and affects the time limit of delivery. Therefore we propose the automatic data matching system for CAD data's integrity. Proposed system is automatic system supporting subsidiary design works. The data matching system consists of three parts; 1) automatic generation of data tables 2) supporting module for checking CAD data's integrity between Drawings 3) automatic generation of spec. sheets. Developed system was tested in LCD equipment manufacture company and was found to be useful system.

Small sized companies have not been successful in systematically applying statistical process control because of insufficient human resources. In this paper we present a case study of automatic checking system for a small sized company which produces various types of gears. A systematic way of automatically measuring gears is proposed and statistical analysis methods are presented. To reduce variation in the measurement data, a standard operating procedure is also proposed. This case study can be helpful to quality assurance practitioners of small sized companies who are willing to develop checking or inspection systems for their products.

YLPODS (Yonsei Laser-ranging Precise Orbit Determination System) is POD system using SLR (Satellite Laser Ranging) data. YLPODS is developed for two main purposes. The first purpose is to verify the result of POD using GPS data. The second purpose is to perform POD using only SLR data. In this study, YLPODS performance test is presented for checking the reliability of POD using only SLR data. To perform POD, the information of CHAMP and TOPEX mission is applied and SLR NP (Normal Point) data is used. The test is performed by checking both range precision and 3D accuracy (radial, along, cross direction). To confirm of 3D accuracy, CHAMP GENESIS orbit and TOPEX JPL orbit of NASA are used.

Landcover map can use to establish basic national environment policy as main data predicting living place, counting pollution like a atmosphere, water and forest part. During the 1998-2005 years, Korean government made landcover maps using satellite image for part of south Korea. Landcover maps are offered free for public purpose to university and institute. So, it used basic data for policy and research parts. There are some problems for application parts because of inconsistency. So, in this study, to estimate accuracy of source data by quality checking for landcover maps. As a result, there are some errors like classification inconsistencies. So, it need verification process for landcover maps.

The quasi-likelihood models which greatly widened the scope of generalized linear models are widely used in data analysis where a likelihood is not available. Since a quasi-likelihood may not appear to be an ordinary likelihood for any known distribution in the natural exponential family, to fit the quasi-likelihood models the standard statistical packages such as GLIM, GENSTAT, S-PLUS and so on may not directly applied. SAS/IML is very useful for fitting of such models. In this paper, we present simple SAS/IML(version 6.11) program which helps to fit and analyze the quasi-likelihood models applied to the leaf-blotch data introduced by Wedderburn(1974), and the problem with deviance useful generally to model checking is pointed out, and then its solution method is mention through the data analysis based on this quasi-likelihood models checking.

The method for evaluating AF's quality and calculating of AF checking time is proposed in this paper. For the purpose, the fuzzy control method is used. To show the effectiveness, the technique is implemented and the performance is verified on a NEC's 16 bit-general purpose micro-controller. The result shows that although the number of AF checking times is reduced, the receiver can find the best frequency faster.

Objective: The purpose of this study is to provide a better understanding of short turn mechanism by describing short turns after kinematic analysis and provide skiers and winter sports instructors with data through which they are able to analyze right postures for turns in skiing in a systematic, rational and scientific manner. Method: For this, a mean difference of kinematic variables (ski-hip angle, ski-shoulder twist angle, pole checking angle, the center of gravity (CG) displacement, trunk forward lean angle) was verified against a total of 12 skiers (skilled and unskilled, 6 persons each), regarding motions from the up-start to down-end points for short turns. Results: There was no difference in a ski-hip twist angle. The ski-shoulder twist angle was large at the up-start point while a pole-checking angle was high at the down-end point in skilled skiers. Concerning the horizontal displacement of CG, skilled skiers were positioned on the right side at the upstart point. No significant difference was observed in the trunk forward lean angle. Conclusion: According to the ski-shoulder twist angle and CG horizontal displacement results, the upper body should be kept leant toward the pole. In addition, big turns should be made via edging and angulation. During pole checking, the hand holding the pole should be thrown and released toward a vector direction of the forearm.
