The aim of this study was to identify how information media about patient safety incidents influences nursing students' knowledge, perception, and confidence in performance toward patient safety. A total of 337 nursing students agreed to participate in this study. Data were collected from the participants between June 4 and June 12, 2018. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and Pearson's correlation coefficient with SPSS 21.0. Participants' scores for knowledge, perception, and performance confidence toward patient safety were $6.43{\pm}1.92$, $41.02{\pm}4.35$, and $39.61{\pm}5.89$, respectively. Patient safety knowledge was significantly different according to age, grade, and patient safety education experience. Patient safety perception was significantly different according to satisfaction with the major, patient safety performance confidence showed statistically significant differences according to grade, patient safety education experience, and major satisfaction. Information media exposure to patient safety incidents on TV and knowledge (r=.32, p<.000) and performance confidence (r=.21, p<.000) toward patient safety had positive correlations. Information media exposure to patient safety incidents on the internet and knowledge (r=.34, p<.000), perception (r=.12, p=.028), and performance confidence (r=.24, p<.000) toward patient safety also had positive correlations. This study provides basic data for nursing education and program development for patient safety management.

Williams, M K., King, E., and Walford, Joan (1969). Brit. J. industr. Med., 26, 202-216. An investigation of lead absorption in an electric accumulator factory with the use of personal samplers. Thirty-nine lead workers and controls, in stable conditions of exposure, each wore personal lead-in-air samplers daily for two weeks. During the second week samples for blood lead, urinary lead, urinary coproporphyrin, urinary $\gamma$-aminolevulinic acid (ALA), the punctate basophil count, and haemoglobin were taken daily. Duplicate estimations were made on one day. The lead exposures of men doing almost identical jobs differed by ratios of up to four to one. This could be attributed on y to personal differences in working habits. The correlation coefficients and regression equations of the biochemical tests with lead-in-air and with each other were determined. The mean values and $95\%$ confidence limits of single determinations of some of the biochemical tests corresponding to the two commonly accepted TLVs of lead-in-air (0-20 and 0-15 mg./$m^{3}$) were calculated from the regression equations. For each biochemical test the variation due to analytical error, the variation from day to day within subjects and the residual variation about the regression on lead-in-air were calculated. Previous estimates of the latter are not known. Excessive confidence may be placed in an index of exposure due to its low coefficient of variation within subjects unless the coefficient of variation between subjects about regression is taken into account. The correction for specific gravity of estimations of lead and ALA in spot samples of urine was found to reduce slightly the residual variation between subjects about the regression on lead-in-air and to increase the correlations with lead-in-air and with the other biochemical tests, but these changes were not statistically significant. The modified method used for estimating blood lead and urinary lead is described and validated.

Purpose: Fuji apples are one of the top selling exports for South Korea bringing in over $233.4 million in 2013. However, during the last few decades, about half of the Fuji apple orchards have been infected by Apple Marssonina Blotch disease (AMB), a fungal disease caused by Diplocarpon mali., which takes about 40 days to exhibit obvious visible symptoms. Infected leaves turn yellow and begin growing brown lesions. AMB promotes early defoliation and reduces the quality and quantity of apples an infected tree can produce. Currently, there is no prediction model for AMB on the market. Methods: The Precision Agriculture Laboratory (PAL) at the University of Florida (UF) has been working with the National Academy of Agricultural Science, Rural Development Administration, South Korea to investigate the use of hyperspectral data in creating an early detection method for AMB. The RDA has been researching hyperspectral techniques for disease detection at their Apple Research Station in Gunwi since 2012 and disseminates its findings to the local farmers. These farmers were surveyed to assess the state of knowledge of AMB in the area. Out of a population of about 750 growers, 111 surveys were completed (confidence interval of +/- 8.59%, confidence level of 95%, p-value of 0.05). Results: The survey revealed 32% of the farmers did not know what AMB was, but 45% of farmers have had their orchards infected by AMB. Twenty-five percent could not distinguish AMB from other symptoms. Overwhelmingly, 80% of farmers strongly believed an early detection method for AMB was necessary. Conclusions: The results of the survey will help to evaluate the outreach programs of the RDA so they can more effectively educate farmers on the identifying, treating, and mediating AMB.

This study was designated to investigate communication barriers of nurses in clinical settings. This study was done in 2 phases, first content analysis on descriptions of 50 nurses in three general hospitals and 40 nursing students on communication barriers for nurses in clinical settings, and second a survey to investigate the factors related to communication barriers and the relation between the nurse's characteristics and the extent of communication barriers in clinical settings from two nurses educators, 13 nursing students who experienced clinical practice and 71 nurses in 11 general hospitals. The results are as follows : 1. Through content analysis, 11 properties of communication barriers for nurses in clinical settings were identified. These were inappropriate communication style as a nurse, lack of professionalism, in appropriate control of emotions, lack of knowledge about the clincal setting, the lack of preparation about content of communication, the problem in trust relation, differences in priorities in needs, uncontroleable situation for nurses, inappropriate nurses' perception about patients, conflict with medical team and inadequate systematic support were identified and grouped in to four categories, communicator, message, feed-back and communication context. 2. The four factors in communication barriers for nurses in the clinical setting were identified and named as ambiguity in the nurses' position, lack of confidence, difference in perspectives with patients and in-adequate nurse-patient relationship. 3. There was a significant difference(F=5.31, P=0.0022, F=3.62, P=0.0316, F=2.80, P=0.067, F=9.01, P=0.0003) among the groups according to work place in rating the extent of the communication barrier in the clinical setting and in the four factors, the nurses working in the psychiatric patient unit rated the communication barrier in the clinical setting lowest among the groups. There was a significant negative correlation between the length of the nurses's carrier and the extent of communication barrier in three factors, ambiguity in the nurses' position, lack of confidence and inadequate nurse-patient relationship.

Purpose: This study was conducted to develop and test the effects of a coronavirus disease 2019 (COVID-19) education program for nursing students. Methods: This study used a non-equivalent control group pretest-posttest design. A total of 71 undergraduate nursing students who had completed a fundamental nursing course and were in their third or fourth year of university participated in this study (experimental group n=38, control group n=33). The COVID-19 education program was developed according to the stages of analysis, design, development, implementation, and evaluation. The program consisted of three weekly sessions that each lasted about two hours. The data were collected from February 26 to March 26, 2022 and were analyzed using the chi-squared, Fisher's exact, and independent t-tests. Results: Knowledge about COVID-19, knowledge about personal protective equipment and attitudes toward COVID-19 were not significantly different between the experimental and control groups. However, significant differences were found between the experimental and control groups regarding their confidence in COVID-19 patient nursing care (t=3.02, p=.004). Conclusion: It was confirmed that the developed program was effective in enhancing the confidence of nursing students in performing nursing for COVID-19. Therefore, it is proposed that the education program developed in this study be used as part of an infection control education program to improve nursing students' abilities to respond to emerging infectious diseases, including COVID-19.

In this study, we investigated methods of quality check for digital basemaps and proposed effective methods of quality check. We used new statistical methods for quality control in order to carry out quality check for digital basemaps. We proposed 2-stage complete sampling and 2-stage cluster sampling method to improve present statistical methods of quality check(1-stage complete sampling method). We estimated error rate and number of omitted objects using simulated data about all delivered digital basemaps and estimated variances about it. We could determine confidence interval about error rate and number of omitted objects.

This paper proposes central monitoring system(PVCMS) based on a TCP/IP network for effective integrating management about photovoltaic systems. We don't gain confidence the result of production simulation, because the output of PV system have many various environmental change factor. So if we can obtain real operated data about each sites and system types to use PVCMS, we can define the environment change factor to compare with simulation data. And this paper try to access about total management and data analysis methods of renewable energy through results analysis to synthesize of the operation.

Using a qualitative method, this paper described briefly the well-being-oriented consumers consciousness toward sustainability concept. The paper identified the major obstacles facing well-being society as evidenced by consumers own experiences for consuming products which are meet the necessity for environmental preservation. Over seventy percent of respondents who had a experience consuming the sustainable products said that they consumed it for themselves and their family's health of all things. Beside their interests about health, they made mention of the safety of sustainable products, high quality of sustainable products, to preserve our environment, confidence in sustainable products, encouragement from others, and curiosity for sustainable products. The respondents who did not consume the sustainable products argued that high price of sustainable products, genuineness of sustainable products, lack of information about sustainable products, unconcern about sustainable products, and difficulty to access to sustainable products were not allowed them from consuming the sustainable products.

Objectives: The aim of the present study was undertaken to investigate the association between communication for chemical hazard information and characteristics of occupational safety and health managers. Subjects and Methods: We surveyed 78 occupational safety and health managers(64 male and 14 female) in 78 chemical manufacturing plants. Data were obtained using a self-reported questionnaire about size and type of company, products, communication system for chemicals and work-related characteristics of occupational safety and health managers. All analyses in this study were performed using SPSS program 12.0. Results: 64.1% of the study participants were occupational health managers aged 39.3 years on average and were graduated from college and university around 90%. 30.0% and of them were majoring in chemistry (engineering chemistry), 18.0% occupational health, 16% nursing and 30.0% others. Occupational safety managers were aged 39.4 years on average, 42.9% of them were majoring in chemistry (engineering chemistry), 21.4% environmental engineering, 10.7% occupational safety and 25% others. 86% of occupational health managers and 71.4% of occupational safety managers were classified as office job. Over 94% of the hazards information for chemicals were delivered by occupational safety and health managers, but about 28.2% workers preferred outside experts who have a profound knowledge about occupational safety and health and understandable. Occupational safety and health managers and workers had difficulties in understanding toxicological information, hazards identification, stability/reactivity, composition/information on ingredients, physical/chemical properties and ecological information. On multiple logistic regression analysis for the 16 heading of material safety data sheet, content of material safety data sheet was significantly associated with education level (odds ratio=0.286, 95% confidence interval=0.105-0.780). The hazard identification (odds ratio=3.947, 95% confidence interval=1.092-14.271) and toxicological information (odds ratio=0.841, 95% confidence interval=0.705-0.998) were significantly associated with type of occupation. Conclusions: This finding implies that the education level, type of occupation and speciality of occupational safety and health managers may affects hazards information delivery.
