Purpose: This study was conducted in order to investigate the relations between knowledge, awareness, and performance of standard precautions among nursing college students. Methods: The participants were 167 students in D city. Data were collected from April 16, 2018 to May 4, 2018 using a questionnaire. Data analysis was performed using the SPSS/WIN program 22.0 using t-test, Pearson's correlation analysis, and Multiple linear regression analysis. Results: Mean knowledge, awareness, and performance of standard precaution scores 19.02, 4.77 and 4.75 awareness was found to positively affect the performance of standard precautiosns. Conclusion: To improve hospital infection control, a customized infection control program should be developed for nursing students by surveying level of knowledge of standard precautions, to select risk groups and to gradually improve knowledge, awareness and performance.

The purpose of this study was to investigate the relationship between attitude toward patient safety, empowerment and awareness, performance of standard precaution for healthcare associated infection control and prevention and to identify the influencing factors of the performance in nursing students. The participants were 185 nursing students on one college in J city, Data collection was conducted from september 10 to 21, 2018. The collected data were analyzed with independent t-test, ANOVA, Pearson's correlation coefficient and stepwise multiple regression using SPSS Statistics 22.0 program. As a result of multiple regression analysis showed that the factors influencing the performance of the standard precaution were awareness, empowerment, participation in the patient safety campaign and the performance was explained by 51.0%. Therefore, In order to improve the performance of standard precaution for nursing students, various convergent education programs should be applied to raise awareness and improve empowerment, and it is necessary to seek ways for nursing students to participate actively in patient safety campaigns.

Recently, the government has actively promoted the introduction of BIM at the national level to improve the efficiency and productivity of the construction industry, and private interest in the application of BIM has also increased. However, despite the large amount of references and information, not much research has been done in quantitative ways to accurately measure the performance of BIM projects. The purpose of this study is to review performance measurement cases using ROI, investment effect analysis, and queue model analysis using domestic and overseas BIM guideline research and to present standard templates that can quantitatively measure BIM performance records according to domestic conditions based on this. Performance measurement trends and cases according to the application of BIM were analyzed, and nine quantification elements were derived from this, and based on this, a performance measurement data collection template at the BIM life cycle stage was prepared. Detailed items and contents were prepared for the nine quantification elements, and the final template consisted of a total of 43 questions, divided into the entire stage (15), the beginning (8), the middle (8), and the latter (12) areas. It is expected that by using the standard template of railway BIM performance records developed in this study, the BIM design stage will be diagnosed and the deficiencies will be supplemented, which will be the basic data for measuring actual quantitative performance in all life cycle performance of future BIM projects.

Recently, the transmission amount of information that each single person requires is growing by development of electron information communication technology. So in this paper we analysis the phase noise characteristics to obtain a most suitable of SNR performance request characteristic by BER on CATV transmission system that satisfy performance request DOCSIS 2.0 standard. Especially we get the parameter value of PLL that satisfy phase noise characteristic request standard using developed simulator. Presented method can be used to obtain a performance request standard connection performance request standard of high speed CATV transmission system in the future.

An experimental apparatus for PIV performance evaluation has been developed. Stardard uncertainty of a two-dimensional cross-correlation PIV system was investigated based upon the standard experimental apparatus, which was devised to model the rigid body rotating flows. For the systematic analysis of the uncertainty introduced by each component (algorithm, CCD camera, frame grabber) of the PIV system, standard images are fed into the component independently. The standard experiments show that 53% of the uncertainty in the present PIV system results from the frame grabber but the errors from the algorithm and digital camera are ignorable.

This paper presents a methodology to enable the tolerances on mating parts of an assembly to be specified and be compatible to the precision of an assembly robot so as to achieve maximum system performance. The measure of performance is defined as the Probability of Successful Assembly (PSA). A typical loose fastener assembly, usually called peg-in-a-hole is investigated. The Geometric Tolerancing System is adopted to represent position tolerances of mating parts. Two models are presented by considering modifiers on a position tolerance, Regardless of Feature Size (RFS) and Maximum Material Condition (MMC). Using these models, it is analyzed how the Standard Limits and Fits recommended by ANSI influence the performance of an assembly robot. For this analysis, the Standard Limits and Fits are transformed to the representation scheme of the Geometric Tolerancing System. Due to low PSAs when the Standard Limits and Fits are taken into account, the effect of chamfers around a hole is also analyzed.

As the architecture of automotive software is complicated and LOC of software increases, there is an increasing demand for standard operating system. OSEK/VDX defines an industry standard for automotive operating system and middleware. This paper introduces an implementation of RTOS(OSCAR-OSEK) based on OSEK/VDX standard. For better speed of scheduling, we suggest a new method for ready queue implementation considering the characteristic of automotive application software. Also we introduce a method for improving the portability of RTOS on various MCUs. And, we show OSCAR-OSEK implementation and performance test results.
