이 연구는 간호대학생들의 혈액 및 체액의 노출실태와 표준주의에 대한 지식, 인지도와 수행도를 파악하여 감염교육을 위한 기초자료로 제시하고자 시도하였다. 연구대상자는 J지역의 간호학과 3, 4학년 간호대 학생 309명이었다. 대상자의 혈액과 체액에 대한 노출경험은 71.5%이었다. 표준주의에 대한 지식 평균점수는 $20.59{\pm}2.05$점이고, 학년, 감염교육 유무 등에서 통계적으로 유의하였다. 인지도의 평균점수는 $4.67{\pm}.36$점이고 연령, 사후조치 없음의 이유 등에서 통계적으로 유의하였고, 수행도 평균점수는 $4.25{\pm}.70$점이며, 혈액 및 체액 접촉에서 유의하였다. 대상자의 표준주의에 관한 지식, 인지도와 수행도와의 관계는 각각 양의 상관관계로 나타났다. 표준주의 수행도에 영향을 미치는 요인으로는 표준주의 인지도(${\beta}=.274$)만이 유의하게 나타나, 표준주의 수행도 변인의 8.6%를 설명하였다. 표준주의의 인지도와 수행도가 낮은 점수의 영역을 중점적으로 보완한 다양한 감염관리 프로그램의 개발이 필요하며, 학생들에게는 임상실습 진입 전, 감염예방에 대한 교육이 강화되어야 할 것이다.

본 연구는 요양병원 간호사의 환자안전문화 인식, 표준주의 지식 및 수행도와의 관계를 파악하기 위해 실시된 서술적 조사연구이다. 요양병원 간호사 134명을 대상으로 2018년 1월 2일부터 6월 4일까지 자료수집이 이루어졌으며, 수집된 자료 분석은 SPSS/WIN 21.0프로그램을 이용하여 t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient으로 하였다. 환자안전문화 인식은 표준주의 지식(r=.192, p=.027), 표준주의 수행도(r=.211, p=.014)와 유의한 양의 상관관계가 있는 것으로 나타났다. 요양병원 간호사의 환자안전문화 정착과 표준주의 수행 증진을 위해서는 체계적인 교육을 통해 표준주의 지식을 함양하고 긍정적인 환자안전문화를 조성할 수 있도록 하여 그 속에서 환자안전과 의료관련감염 관리의 중요성을 스스로 인식하고 실천하도록 해야 갈 것이다.

Objective: Little is known about the effects of using different expert-determined reference standards when evaluating the performance of deep learning-based automatic detection (DLAD) models and their added value to radiologists. We assessed the concordance of expert-determined standards with a clinical gold standard (herein, pathological confirmation) and the effects of different expert-determined reference standards on the estimates of radiologists' diagnostic performance to detect malignant pulmonary nodules on chest radiographs with and without the assistance of a DLAD model. Materials and Methods: This study included chest radiographs from 50 patients with pathologically proven lung cancer and 50 controls. Five expert-determined standards were constructed using the interpretations of 10 experts: individual judgment by the most experienced expert, majority vote, consensus judgments of two and three experts, and a latent class analysis (LCA) model. In separate reader tests, additional 10 radiologists independently interpreted the radiographs and then assisted with the DLAD model. Their diagnostic performance was estimated using the clinical gold standard and various expert-determined standards as the reference standard, and the results were compared using the t test with Bonferroni correction. Results: The LCA model (sensitivity, 72.6%; specificity, 100%) was most similar to the clinical gold standard. When expert-determined standards were used, the sensitivities of radiologists and DLAD model alone were overestimated, and their specificities were underestimated (all p-values < 0.05). DLAD assistance diminished the overestimation of sensitivity but exaggerated the underestimation of specificity (all p-values < 0.001). The DLAD model improved sensitivity and specificity to a greater extent when using the clinical gold standard than when using the expert-determined standards (all p-values < 0.001), except for sensitivity with the LCA model (p = 0.094). Conclusion: The LCA model was most similar to the clinical gold standard for malignant pulmonary nodule detection on chest radiographs. Expert-determined standards caused bias in measuring the diagnostic performance of the artificial intelligence model.

In the previous test, the verification of the standard floor impact source was carried out comparing the physical characteristics with living impact sources. The result was appeared the validation of the standard impact source was very low because of differences of physical characteristics. This study aims to evaluate annoyance and loudness of standard impact source which is used for the measurement of floor impact sound, and to compare the annoyance and loudness of living impact sources which are produced in real life. The impact sources considered are tapping machine, tire and impact ball as standard sources, and nine real sources which were chosen from the existing researches. The result showed differences of annoyance and loudness between standard impact sources and living impact sources, which means the standard impact sources may rate the performance of floor system inappropriately. In the future, the rating method should be examined how the standard impact sources are similar with real sources in the point of rating the performance of floor system.

In case of the Korea Railroad, when we would decide the track structure, it has been introduced the whole track structure system based on only the foreign application cases and data offered by manufacturers without the process of the objective performance verification. The value of property for track materials, derived from the calculation of track structure, was hard to perform the objective performance evaluation among track structure systems because each manufacturer adopted the different test method and standard. To solve the above-mentioned problem, it should suggest the technical and objective evaluation method about the performance of track materials and meet with the standard of High Speed railroad and international railroad through the establishment and revision of performance standard. In the objective and technical respects, it will be a major role to decide the track structure. In this paper, I would like to summarize the case which was improved the problem of test method and standard exposed from the performance verification of Rail Fastening System among the track structure systems of High speed railroad.

Objectives: The purpose of this study was to investigate the status of exposure to blood and body fluid and factors affecting on blood and body fluid exposure of nursing students including knowledge, performance regarding standard precautions. Methods: 280 nursing students in D-city and S-city participated in this study. Data collection was conducted from January to March 2012. Students' knowledge and performance on standard precautions of infection control in hospitals were measured using the measurement developed by Hong(2010). Data analysis was performed using descriptive statistics, t-test, one way-ANOVA, ${\chi}^2-test$, Pearson correlation coeficient, logistic regression by the SPSS WIN 18.0 program. Results: 58.6 percent of subjects experienced a exposure to blood and body fluid. The level of nursing students' knowledge level regarding standard precautions was $22.44{\pm}2.11$ and performance level was $4.31{\pm}0.50$. The factors affecting on blood and body fluid exposure of nursing students were knowledge level and education type about infection control. Conclusions: Based on the findings of this study, to decrease the exposure to blood and body fluid of nursing students, a proper education need to be stressed to improve nursing students' infection control knowledge and awareness.

The purpose of this study was to investigate whether the standard models for rural housing and wooden housing model have performance for hygrothermal and to propose a way of improvement relevant to hygrothermal performance for those models. All of the models to be analyzed were found to have some parts that were absent of stability in terms of performance for hygrothermal. In the process of analyzing the causes and proposing improvement measures, the following conclusions were derived. Fist, The exterior surface of the structure should be composed of a structure with good moisture permeability, and for the interior surface, a variable vapor retarder paper should be applied in consideration of the reverse condensation phenomenon in summer. Second, in terms of performance for hygrothermal, applications of external insulation plaster finish to the exterior wall or of ventilation method using a rafter vent on the roof should be avoided. Third, a rain screen method with a ventilation layer should be applied to the exterior wall, and a method of constructing ventilation layer separated from the insulation layer with a vapor retarder paper should be applied to the roof. Fourth, the application of insulation materials having capillary action, such as wood fiber insulation board or cellulose insulation board, contributes to more stable performance for hygrothermal.
