Purpose: The balance between miscanthus production and its cost effectiveness depends greatly on its moisture content during post processing. The objective of this research was to measure the moisture content using a non-destructive and non-contact methodology for in situ applications. Methods: The moisture content of comminuted miscanthus was controlled using a closed chamber, a humidifier, a precision weigher, and a real-time monitoring software developed in this research. A CMOS sensor equipped with $50{\times}$ magnifier lens was used to capture magnified images of the conditioned materials with moisture content level from 5 to 30%. The hypothesis is that when light is incident on the comminuted particles in an inclined manner, higher moisture content results in light being reflected with a higher intensity. Results: A linear regression analysis for an initiative hypothesis based on general histogram analysis yielded insufficient correlations with low significance level (<0.31) for the determination coefficient. A significant relationship (94% confidence level) was determined at level 108 in a reverse accumulative histogram proposed based on a revised hypothesis. A linear regression model with the value at level 108 in the reverse accumulative histogram for a magnified image as the independent variable and the moisture content of comminuted miscanthus as the dependent variable was proposed as the estimation model. The calibrated linear regression model with a slope of 92.054 and an offset of 32.752 yielded 0.94 for the determination coefficient (RMSE = 0.2%). The validation test showed a significant relationship at the 74% confidence level with RMSE 6.4% (n = 36). Conclusions: To compensate the inconsistent significance between calibration and validation, an estimation model robust against various systematic interferences is necessary. The economic efficiency of miscanthus, which is a promising energy resource, can be improved by the real-time measurement of its crucial material properties.

In the product development stage, it is very important to ensure demanded quality level before moving to the full-scale manufacturing. For example, in developing guided weapons, live-fire tests are required to verify the final performance of the weapons which are very expensive. The quality evaluation of the guided weapons needs destructive testing, which makes it necessary to test as small number of samples as possible. This paper presents sampling inspection plans and calculating system for finite population guided weapons, which can meet the demanded quality level and confidence level with the minimum number of performance tests. The result of this paper can be useful for any kind of costly destructive testing.

Purpose: This study was conducted to assess the factors that affect the confidence of nurses at small and medium-sized hospitals in the control of infections caused by multidrug-resistant organisms and to establish basic data for the interventional strategy to improve the nurses' execution of the control of infection caused by multidrug-resistant organisms. Methods: A total of 154 nurses working at four small and medium-sized hospitals situated in City C were selected as participants of this study. Data were collected using a structured questionnaire and analyzed using the IBM SPSS 21.0 software. Results: Confidence in controlling infections caused by multdrug-resistant organisms had a positive correlation with the level of knowledge of this control and the health beliefs of the nurses. Factors that affect nurses' confidence in controlling infections caused by multidrug-resistant organisms included perceived benefits (β=.431, p<.001) and knowledge (β=.354, p<.001) with an explanatory power of 36.4%. Conclusion: It was found that the nurses have higher confidence in executing their duties with higher perceived benefits of and knowledge about the control of infections caused by multidrug-resistant organisms. As such, it is deemed necessary to establish strategies to elevate the advantages of and knowledge about infection prevention activities at the time of training/education on controlling infections caused by multidrug-resistant organisms.

This descriptive study aimed to determine the effects of community based health education program for pregnant women on their confidence in labor and breastfeeding. Data were obtained using several questionnaires and administered to 174 pregnant women who have participated (n=49) and have not participated(n=125) in health education program, and 244 mothers of infants who lived in one city in Kyunggi province. Summaries of finding were as follows; First, pregnant women who have participated in health education program showed significantly higher score in confidence in labor than those who have not. Also, confidence in labor was different according to the level of education. Second, pregnant women participated in health education program showed higher score in knowledge and attitude on breastfeeding, but the differences were not significant. Knowledge on breastfeeding was higher in multipara. More positive attitude on breastfeeding was found in working mothers and highly educated mothers. Third, $54.1\%$ of mothers continued breastfeeding over six months. Main reasons for discontinuing breastfeeding were lack of breast milk amount, and health problems in infants and mothers. In this study, we could identify the positive effects of health education program for pregnant women provided by public health center, and find the related factors of confidence in labor and breastfeeding. Community based health education program for pregnant women, especially for vulnerable group should be expanded.

Purpose: This study aimed to develop a nursing simulation learning module for coronavirus disease 2019 (COVID-19) patient-care and examine its effects on clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient care for nursing students. Methods: A non-equivalent control group pre- and post-test design was employed. The study participants included 47 nursing students (23 in the experimental group and 24 in the control group) from G City. A simulation learning module for COVID-19 patient-care was developed based on the Jeffries simulation model. The module consisted of a briefing, simulation practice, and debriefing. The effects of the simulation module were measured using clinical reasoning competence, clinical competence, performance confidence, and anxiety in COVID-19 patient-care. Data were analyzed using χ²-test, Fisher's exact test, t-test, Wilcoxon signed-rank test, and Mann-Whitney U test. Results: The levels of clinical reasoning competence, clinical competence, and performance confidence of the experimental group were significantly higher than that of the control group, and the level of anxiety was significantly low after simulation learning. Conclusion: The nursing simulation learning module for COVID-19 patient-care is more effective than the traditional method in terms of improving students' clinical reasoning competence, clinical competence, and performance confidence, and reducing their anxiety. The module is expected to be useful for educational and clinical environments as an effective teaching and learning strategy to empower nursing competency and contribute to nursing education and clinical changes.

Purpose: This study aims to examine perceived safety management in teachers working for young children with disabilities, to grasp the state and problems of safety management and first-aid education at daycare center for young children with disabilities, and to provide basic materials to develop programs for safety management and first-aid education. Results: 1. For the perception items of accident possibility in daycare centers, career with more than 10 years had higher response in 'very high' and 'moderately high' than 'moderately or very low' and statistically significant difference was found(p < .05). 2. For the perception items of accident prevention in daycare centers, no teaches with at least college education thought that 'it was not possible to prevent' and most of them thought that 'it was totally possible to prevent' and statistically significant difference was found(p < .05). 3. For the performance level of safety management and first-aid items, forty and over(4.73) showed higher than age of 20-29(4.32) and 30-39 of age(4.26) and statistically significant difference was found(p < .05). 4. For the knowledge level of safety management and first aid items, the highest religion was found as Christian(16.96), followed by Catholic(15.33), Buddhism(14.91), and no religion(15.81) and statistically significant difference was found(p < .05). 5. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed safety management and first-aid education( 4,48) had higher performance score than those who did not (4.17) and statistically significant difference was found(p < .05). 6. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed first-aid education(2.77) had higher confidence than those who did not(2.35) and statistically significant difference was found(p < .05). Conclusion: The results suggest that safety management and first-aid education in teachers working for daycare center for young children with disabilities was closely correlated with knowledge and performance levels. Thus, it is necessary to provide continuous safety management and first-aid education for teachers working for day care center for young children with disabilities through regular in-service training. Also further research should be conducted with all subjects and various regions who contact with young children with disabilities.

이 연구는 사회복지사의 직무특성이 직무만족에 미치는 영향을 고찰함으로써 사회복지사의 직무 설계 시 고려해야 할 요소를 밝혀내기 위해 시행되었다. 설문은 사회복지관의 사회복지사와 의료사회복지사 240명이 응답한 결과를 토대로 분석하였다. 연구결과 사회복지기관 사회복지사의 직무만족에는 자율성, 피드백, 정체성, 전문성, 필요성의 직무특성과 자기효능감이 영향을 미쳤으며, 의료사회복지사의 직무만족에는 필요성과 자기효능감, 성별, 직위만이 영향을 미쳐, 직무특성요인이 부분적으로 결과변수에 영향을 미치는 것으로 나타났다. 특히 핵크맨과 올드햄(1975)의 핵심직무특성보다는 정체성, 전문성, 필요성의 직무특성 영향력이 보다 강한 것으로 나타나, 사회복지사의 지식과 기술, 기법 외에 관점이나 정체성, 필요성 등을 강조하는 접근이 필요한 것으로 나타났다. 또한 자기효능감이 직무만족에 미치는 영향력이 다른 변수보다 강하였고, 직무 특성이 직무만족에 영향을 미침에 있어 부분적인 매개역할을 하고 있는 것으로 나타나, 사회복지사의 자기효능감을 증진시키기 위한 교육과 지지적인 환경, 수퍼비전 등이 필요한 것으로 나타났다. 이 연구는 핵크맨과 올드햄(1975)의 핵심직무특성 모형을 사회복지조직에 적용한 연구로, 직무설계 시 사회복지실천현장의 특성별로 달리 나타나는 직무특성 요인을 감안한 직무의 설계와 재설계를 통하여 사회복지사 효율성을 도모해야 할 필요성을 제기하고 있다.
