The study was done to identify relations among moral sensitivity, self-leadership, fatigue and compliance with standard precautions and to identify the influencing factors on compliance with standard precautions for intensive care nurses. Data were collected from 153 intensive care nurses in March 2019 and were analyzed using Descriptive statistics, Pearson correlation coefficients, and Stepwise multiple regression with SPSS/WIN 24.0 version. The compliance with standard precautions has positive correlation with their self-leadership (r=.17, p=.042). The self-leadership (β=.17, p=.042) was a significant predictor of the compliance with standard precautions. It was statistically significant (R²=.03, F=4.21, p=.042). Based on the findings of this study, each institution needs to make efforts to strengthen the capacity of nurses for self-leadership.

This study aimed to explore the influences of safety attitude for patient and moral sensitivity in practice of standard precaution in small and medium hospital nurses. Data were collected from 150 small and medium hospital nurses in January 11, 2021 to January 22, 2021 and were analyzed using Descriptive statistics, Independent t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression. Practice of standard precaution was significantly correlated with safety attitude for patient (r=.539, p<.001) and moral sensitivity(r=.249, p=.002). Practice of standard precaution was associated safety attitude for patient, and work unit with 33.8% of the variance(F=18.47, p<.001). Based on the findings of this study, each institution needs to make efforts to strengthen the safety attitude for patient of small and medium hospital nurses for practice of standard precaution.

The purpose of this study was to examine relationships among empowerment, awareness and performance on standard precautions and identify the factors that affect performance of standard precaution in nursing students experiencing clinical practice. The data were collected from 168 nursing students who experienced clinical practice in the two colleges located Jeonnam. The data were analyzed by descriptive statistics, t-test, ANOVA, Scheffe, Pearson's correlation coefficient, and stepwise multiple regression with SPSS 20.0 program. The result of the stepwise multiple regression indicates the awareness predict 77.7% (F=579.84, p<.001) in the performance of standard precaution. Therefore, it is necessary to develop awareness of the standard precaution strategy program for improving the performance of standard precautions in nursing students experiencing clinical practice.

In this paper, the performance of uplink WCDMA systems was analyzed using the SGA (Standard Gaussian Approximation) method and the SIGA(Simplified Improved Gaussian Approximation) method adopted for the performance analysis in conventional DS-CDMA systems. The performance of bandlimited WCDMA systems was analyzed using the SGA and SIGA method, and computer simulations were performed in AWGN environments having multiple access interference. It was shown that the performance analysis of uplink bandlimited WCDMA systems using the SIGa method may be very efficient through various computer simulations with verying spreading factors, roll-off factors, and signal-to-noise ratios.

This study was performed to validate reference materials (RMs) for proficiency testing (PT) in waste inter-laboratories. Dioxin RMs were prepared from fly ash in industrial incinerators. The relative standard deviations (RSDs) of analytical results were 2.6~15.7% for the dioxin RMs in 10 replicates (between and withinbottles). Data were collected and statistical analysis was performed by the One-way ANOVA test. The combined uncertainties of target isomers in dioxin analysis were 0.114~7.091.

Since new issues and topics are emerging in the information and library science fields, diverse needs are identified to enhance the curriculum of library and information science education. This study investigated curriculum of library and information science in US and identified the topics of classes in the curriculum by the three aspects such as competency areas, scientific and technology category, and research fields. Consequently, topics related various information technology including system design and implement are the most popular topics in all analyses. Library and information center management and user service are also major topics of the curriculum.

An inductively coupled plasma mass spectrometry (ICP-MS) instrument equipped with flow injection-hydride generation system was used for the determination of trace arsenic in seawater sample. The accuracy in this method was verified by the analysis of certified reference materials (CRM) of seawater (CASS-4, NASS-5). The analytical results agreed with certified value within the range of uncertainty. The expanded uncertainties for CASS-4 and NASS-5 in this experiment were ranged from 6.2% to 6.8% obtained from repeated analyses of the CRMs (n=5). The detection limit of $As^+$ (m/z=74.9216) in this method was confirmed about 0.01 ug/kg. Linearity obtained from calibration curve of arsenic was excellent ($R^2=1$). The detection at $As^+$ (m/z=74.9216) and $AsO^+$ (m/z=90.9165) by using oxygen reaction gas in DRC mode was compared. Sensitivity at $AsO^+$ (m/z=90.9165) was decreased about 25-fold, but the analytical results are the same that at $As^+$ (m/z=74.9216).

Recently, policy trends related to various information including the geospatial information have changed to openness and sharing. Therefore, it is necessary to apply geospatial standards to ensure a high level interoperability across heterogeneous geospatial information systems. These geospatial standards are essential to advancing data access, query, management, processing and interoperability of geospatial information systems. However, geospatial information companies which provide GIS software and service or construct geospatial data have been many difficulties to implement and adopt geospatial standards, because the geospatial standards of Korea were not systematically managed. So this study analyzed the various problems such as redundancy, version-mismatch and similarity of domestic geospatial standards through reviewing the present status of domestic geospatial standards as well as the international geospatial standards. Moreover, it is judged that the result of this study will be able to efficiently contribute to the domestic policy on geospatial standards for management, organization and laws in the National Spatial Data Infrastructure.

This study examines how scientists understand standardization and standardization policy in the Korean national R&D context and analyze future policy direction of standardization policy. Interview with 15 scientists at universities and government-funded research institutes who have participated national R&D (particularly in the field of technology convergence) were conducted. The results show that considerations of standardization at the process of technology convergence is somewhat different from them at the process of general R&D. Also, considerations of standardization at the process of technology convergence is needed at the later time within the R&D time schedule because of low visibility and forecasting on the technology convergence outcome. It finds that "standardization by private sector" is the future policy direction in Korea. The government needs to be remained as "helper" for private sector to lead standardization in a globalized market

An application of the instrumented indentation technique has been expanded from the measurements of hardness and elastic modulus to the analysis of residual stress. A slope of the indentation loading curve increases (or decreases) according to compressive (or tensile) residual stress. A theoretical equation has been established for quantifying residual stress from the slope change. However, a precise observation of the remnant indents is indispensible because the theoretical approach needs actual contact information. In addition, the conventional hardness test is still used for predicting the residual stress distribution of welded joints. Thus, we observed the three-dimensional morphologies of the remnant indents formed on artificial stress states and analyzed stress effects on morphological recovery of the indents. First, a depth recovery ratio, which has been regarded as a sensitive stress indicator, did not show a clear dependency with the residual stress. Thus an analysis on volumetric recovery was tried in this study and yielded a inverse proportional behavior with the residual stress. In addition, an elastic to plastic volume recovery ratio showed more significant correlation with the residual stress.
