Purpose: The aim of this study was to identify the status of performance on standard precautions among nursing students and to examine the mediating effects of internal health locus of control on the relationship between awareness and performance on standard precautions of hospital-acquired infection control. Methods: The participants in this study were 134 nursing students. The measurements included a standard precautions awareness and performance scale, and a multidimensional health locus of control scale. Data were analyzed using independent t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient, and simple and multiple regression techniques. Mediation analysis was performed by the Baron and Kenny's method and Sobel test. Results: The mean score of standard awareness, standard performance, and internal health locus of control about standard precaution were $174.30{\pm}9.08$; $169.48{\pm}12.04$; and $20.43{\pm}2.82$; respectively. There was a positive correlation between standard awareness and performance (r=.414, p<.001). Also, standard awareness was significantly correlated with internal health locus of control (r=.413, p=.014). Internal health locus of control showed partial mediating effects in the relationship between awareness and performance. Conclusion: The results indicate a need to improve the internal health locus of control of nursing students. Therefore, an internal health locus of control improvement program should improve performance on standard precautions for patients and themselves.

Purpose: This study is to establish a structural model for standard precautions compliance of nursing students. This conceptual model was based on the IMB (Information-Motivation-Behavioral skills) model of Fisher and Fisher. Methods: Data were collected from October 12 to December 1, 2020, and the subjects were nursing students from G metropolitan city and J province, and the data of a total of 334 subjects were analyzed. For data analysis, this study used the SPSS 24.0 and AMOS 24.0 programs. Results: The hypothetical model showed a good fit to the data: 𝑥²=106.46 (p<.001), 𝑥²/df=2.54, RMSEA=.07, SRMR=.04, CFI=.96, TLI=.94. It was confirmed that the variables that have a statistically significant influence on the standard precautions compliance in nursing students were in the order of self-efficacy, social support, personal attitude, and standard precautions knowledge. The model explained 48.3% of the variance in standard precautions compliance of nursing students. Conclusion: It is necessary to develop and apply various specialized extracurricular programs that can induce an individual attitude toward observing standard precautions compliance in a positive direction in relationships with teachers and peers and gain their support.

Purpose: The purpose of this study was to examine knowledge, perception, safety climate and compliance with hospital infection standard precautions and to identify the factors influencing nurse's compliance with standard precautions. Methods: Using the structured survey, data were collected from 292 nurses working at 4 general hospitals in the metropolitan city Seoul in October, 2008. Data were entered and analyzed with SPSS 12.0. Results: The majority of nurses were female with a mean age of 27.8. The mean score for knowledge of standard precautions was 21.2 out of 25. The nurses lacked knowledge on reusable gloves or gowns. Nurses perceived use of protective devices may not only increase time strain but also hinder development of therapeutic relationships with patients. Of safety climate factors, lack of time was the most frequently reported barrier to compliance with standard precautions. Knowledge, perception, and safety climate explained 16.1% variance of compliance with standard precautions. Conclusion: To improve nurses' compliance with standard precautions, provision of education and support for safety climate are necessary.

일반화 대칭 변환 (generalized symmetry transform, GST)은 주어진 영상에서 사전 분할이 없이 국부성과 반사 대칭성을 결합하여 대칭을 측정하고 관심 영역을 추출한다. GST의 거리 가중치 함수에서 국부적인 대칭성이 반영되며 이 함수의 표준 편차 u에 의해 GST의 수행 범위가 조절된다. 넓은 관심영역을 추출하기 위해 반지름 r이 큰 검색영역 내에서의 대칭성이 추출될 필요가 있다. 이에 따라서 GST의 수행시간은 r에 따라 2차적으로 증가하게 된 본 논문에서는 이를 개선하기 위해 선택적 방향 주의를 가지는 수정된 스캔라인 GST를 제안한다. 제안된 GST는 기존의 GST와 유사한 대칭 특성을 추출하지만 선택적 방향의 기울기만을 고려한 스캔라인 위의 에지 화소쌍에서 GST를 수행함으로써 r에 따라서 이의 수행시간이 선형적으로 증가된다 특히 r이 큰 경우에 선택적 방향에 대해서만 적용하면 기존의 GST의 계산량이 비대해지는 단점을 보완해 줄 수 있다. 제안된 GST가 기존의 GST보다 시간적으로 효과적이며 유용하다는 것이 여러 종류의 영상에 대한 실험으로 확인되었다.

Purpose: This study was conducted to identify the effects of organizational culture for the infection control and self-efficacy on compliance with standard precautions of emergency room nurses. Methods: This cross-sectional descriptive study was conducted from 1st July to 3rd August, 2017. The participants were 200 nurses working in emergency rooms. The data was collected using structured self-report questionnaires. Results: The average scores for the organizational culture for infection control, self-efficacy and compliance with standard precautions were 5.54, 3.65, and 4.31, respectively. The organizational culture for infection control (r = .59, p< .001) and self-efficacy (r= .28, p< .001) were found to have a positive, meaningful correlation with compliance with the standard precautions. Multiple regression analysis showed that compliance with standard precautions was significantly affected by the organizational culture for infection control (${\beta}=0.55$, p< .001) and self-efficacy (${\beta}=0.13$, p= .033). Conclusion: The results for this study indicate that the organizational culture for infection control and self-efficacy were highly influential factors affecting compliance with standard precautions of emergency room nurses. Therefore, in order to improve the nurses' use of the standard precautions, it was necessary to develop and evaluate a program that considers the environmental factors and self-efficacy.
