This study was conducted to investigate the degree of nurses' knowledge, attitudes, and compliance with hospital infection standard precautions. The study subjects were nurses in a university hospital in Daegu, South Korea, and a self-administered survey was carried out using a standardized questionnaire from 1st to 15th August, 2012. A total of 187 questionnaires were used for analysis. Those who were injured by a syringe needle for the last year accounted for 29.96%, and those exposed to patients' blood or body fluid on their damaged skin/mucous membranes accounted for 26.2%. There were statistically significant differences in attitude and compliance according to safety environment for hospital infection standard precautions. The knowledge score of the subjects about standard precautions was $15.30{\pm}1.51$ on a 19 point scale and had significant difference according to the subjects' education level. The attitude score was $2.86{\pm}0.49$ on a 4 point scale and had significant difference depending on how experienced they were on the career. The compliance score was $3.41{\pm}0.38$ on a 4 point scale and had significant difference depending on their age and their experience on the career. In conclusion, it can be said that systematic and continuous practical training is required to improve compliance with standard precautions. Particularly, it is needed to provide less experienced nurses with educational opportunities along with their supervisors' ongoing attention and position personnel appropriately.

The usage of the correct combustion properties of the treated substance for the safety of the process is critical. For the safe handling of n-nonane being used in various ways in the chemical industry, the flash point and the autoignition temperature(AIT) of n-nonane was experimented. And, the explosion limit of n-nonane was calculated by using the flash point obtained in the experiment. The flash points of n-nonane by using the Setaflash and Pensky-Martens closed-cup testers measured $31^{\circ}C$ and $34^{\circ}C$, respectively. The flash points of n-nonane by using the Tag and Cleveland open cup testers are measured $37^{\circ}C$ and $42^{\circ}C$. The AIT of n-nonane by ASTM 659E tester was measured as $210^{\circ}C$. The lower explosion limit by the measured flash point $31^{\circ}C$ was calculated as 0.87 vol%. And the upper explosion limit by the measured upper flash point $53^{\circ}C$ was calculated as 2.78 vol%. It was possible to predict lower explosion limit by using the experimental flash point or flash point in the literature.

A tumor is an abnormal mass of tissue that arises when cells divide more than they should or do not die when they should. The cellular decision regarding whether to undergo division or death is made at the restriction (R)-point. Consistent with this, an increasingly large body of evidence indicates that deregulation of the R-point decision-making machinery accompanies the formation of most tumors. Although the R-point decision is literally a matter of life and death for the cell, and thus critical for the health of the organism, it remains unclear how a cell chooses its own fate. Recent work demonstrated that the R-point constitutes a novel oncogene surveillance mechanism operated by R-point-associated complexes of which RUNX3 and BRD2 are the core factors (Rpa-RX3 complexes). Here, we show that not only RUNX3 and BRD2, but also other members of the RUNX and BRD families (RUNX1, RUNX2, BRD3, and BRD4), are involved in R-point regulation.

Three-dimensional (3D) models have become crucial for improving civil infrastructure analysis, and they can be used for various purposes such as damage detection, risk estimation, resolving potential safety issues, alarm detection, and structural health monitoring. 3D point cloud data is used not only to make visual models but also to analyze the states of structures and to monitor them using semantic data. This study proposes automating the generation of high-quality 3D point cloud data and removing noise using deep learning algorithms. In this study, large-format aerial images of civilian infrastructure, such as cut slopes and dams, which were captured by drones, were used to develop a workflow for automatically generating a 3D point cloud model. Through image cropping, downscaling/upscaling, semantic segmentation, generation of segmentation masks, and implementation of region extraction algorithms, the generation of the point cloud was automated. Compared with the method wherein the point cloud model is generated from raw images, our method could effectively improve the quality of the model, remove noise, and reduce the processing time. The results showed that the size of the 3D point cloud model created using the proposed method was significantly reduced; the number of points was reduced by 20-50%, and distant points were recognized as noise. This method can be applied to the automatic generation of high-quality 3D point cloud models of civil infrastructures using aerial imagery.

This study was designed to identify the relationship between health perception arid health promoting behavior in the elderly. The subjects for this study were 92 persons over 65, who could be easily met in households, pavilions for the aged, and parks. The data were collected during the period from March 24th to April 12th, 1997 by interviews with a structured questionnaire. The instruments used for this study are as follows: The Health Perception Questionnaire developed by Ware (1979) and translated by Yu Ji-Su(1985). The Health Promotion Lifestyle Profile(HPLP) developed by Walker, Sechrist & Pender (1987) and partially amended by the author of this study. The Health Promotion Lifestyle Profile(HPLP) was parameterized by nutrition, exercise, stress management, self actualization, health responsibility, and interpersonal support. The data was analyzed by frequency, percentage, mean, standard deviation, t - test, ANOVA, and Pearson's correlation using an SPSS program. The results of this study were as follows: 1. Hypothesis 1 : 'The higher the level of health perception in the elderly, the higher the practice of health promoting behavior in the elderly' was supported(r=0.449, p<0.001). 2. The health perception mean score on a four point scale was 2.564. 3. For health promoting behavior, the mean score on a four point scale was 2.560. The factor of the highest mean score was interpersonal support(2.850) and factor of the lowest mean score was exercise(1.964). 4. Among the general characteristic variables, sex(t=4.12, p<0.001), religion(t=2.47, p<0.05), education(F=3.27, p<0.05), marital status (t=2.22, p<0.05), living situation(F=3.50, p<0.05), and hobby(t= -2.57, p<0.05) showed strong connections to health perception. 5. Among the general characteristic variables, religion(t = 1.83, p<0.05), and marital status(t= 2.12, p<0.05) showed strong connections to health promoting behavior. In conclusion, this study revealed that health perception is an important factor related to health promoting behavior in the elderly. The general characteristic variables showed strong connections to health perception and health promoting behavior. Therefore, nurses should consider health perception and general characteristic variables when they plan nursing intervention for the elderly. Also, educational programs encouraging constructive health perception should be developed.

The purpose of this study was to examine the influence of oral health education experience on needs for oral health education in children and adolescents in elementary and secondary schools. A self-administered survey was conducted on the students in elementary, middle and high schools located in the city of Mokpo, South Jeolla Province, from October 1 to 31, 2018. The data that were collected from 327 students were analyzed by SPSS 21.0. Statistical data on frequency, percentage, mean and standard deviation were obtained, and t-test, one-way ANOVA, correlation analysis and logistic regression analysis were carried out. The findings of the study were as follows: First, the subjects got 2.25 on a three-point scale in self-rated oral health status. This score was above average, which indicated that the students thought they were in good oral health. As for problems with oral health, dental caries was given the highest score of 2.48 on a five-point scale, followed by oral malodor with 2.35. Second, the students who experienced oral health education accounted for 69.1 percent, and the students who felt the need for this education represented 82.6 percent. As for educational content desired, the biggest group of 57.8 percent hoped to learn about how to prevent and manage dental caries, and the second largest group of 17 percent wanted to learn about how to take care of oral health during orthodontic treatment. Third, as a result of investigating the state of oral health education by the grade of school, the elementary school students had more oral health education experience than the middle and high school students, and the middle school students placed the most importance on the necessity of oral health education. The differences were statistically significant. Fourth, as a result of analyzing the correlation between oral health education experience and the necessity of oral health education, the students who had more oral health education experience asked more for this education, which implies that there was a statistically significant positive correlation. The findings of the study ascertained that oral health education should be provided for students in childhood and adolescence to boost the level of their oral health knowledge and change their oral health attitude in a positive manner. If oral health practice programs that connect schools, local communities and families with one another are developed to guide the oral health behaviors of teenagers in the right direction, it will make a contribution to the promotion of oral health.

Home health care system in Korea has been classified into three types of home care programs based on different laws and regulations; for example, home health care nursing(HHCN) is based on medical laws, visiting health care nursing (VHCN) is based on long-term health care insurance, and visiting health care(VHC) is based on the regional health care act. HHCN in Korea has taken on an important role under the mandate of the national health care system since 2000. VHCN will commence its role under the long term health care insurance system in 2008. The strengthening of VHC commanded health promotion and prevention for vulnerable families in the community in 2007. This is an important turning point for increasing quality management for home health care program; it suggests certain possibilities for building a foundation for further changes in the service delivery structure. Accordingly, the home health care policy makers in Korea have a major function and role that consists of developing an agenda and alternatives for policy making in a systematic manner and clearly presenting implementation strategies for elderly health care system.

Though p values give information on statistical significance, they are confounded with the sample size. Effect size can make up the weak point, by providing information on the actual effect which is independent of the sample size. Therefore, reporting the effect size as well as the p value is recommended.
