This study aimed to develop a mobile separating and sorting device for discharge sites to separate and sort mixed construction waste generated in small and medium scale in small provincial cities into inorganic materials and combustible materials. The study results can be summarized as follows: 1) As a result of analyzing the existing domestic technology for the separating and sorting mixed construction waste, a device sorting the waste by fusing the vibration screen, disc screen, air blowing methods and the separating and sorting the combustible waste is applied in Korea. 2) In foreign countries, the air blowing, screen, gravity sorters are used for separating and sorting combustible waste in the same way as in Korea. Especially German T Company suggests a construction waste separating and sorting system using an optical sorter. 3) As for the test device for separating and sorting mixed construction waste to be buried in landfill, the processing capacity was set as 16 tons per day. 4) For separating and sorting inorganic materials by granularity, this study set a trommel with two types of diameter as a basic. To operate the mobile all-in-one system, the device is designed to locate a conveyor, a combustible waste conveying device, inside of the trommel. 5) The device is designed in a mobile mode under the concept of primary separating and sorting device, and it can be transported using a 2.5-ton truck minimum. The diameter and length of the trommel are designed to be within 1500mm and 3000mm, respectively. In a further study, an optimized separating and sorting technology is planned to be presented through an experimental study for processing efficiency analysis at the mixed construction waste site by manufacturing the pilot experiment facility reflecting the design elements in the result of this study.

Although 'assessment for learning' rather than 'assessment of learning' has been emphasized recently, student learning before examinations is still unclear. The purpose of this study was to investigate pre-assessment learning activities (PALA) and to find mechanism factors (MF) that influence those activities. Moreover, we compared the PALA and MF of written exams with those of the clinical performance examination/objective structured clinical examination (CPX/OSCE) in third-year (N=121) and fourth-year (N=108) medical students. Through literature review and discussion, questionnaires with a 5-point Likert scale were developed to measure PALA and MF. PALA had the constructs of cognitive and meta-cognitive activities, and MF had sub-components of personal, interpersonal, and environmental factors. Cronbach's ${\alpha}$ coefficient was used to calculate survey reliability, while the Pearson correlation coefficient and multiple regression analysis were used to investigate the influence of MF on PALA. A paired t-test was applied to compare the PALA and MF of written exams with those of CPX/OSCE in third and fourth year students. The Pearson correlation coefficients between PALA and MF were 0.479 for written exams and 0.508 for CPX/OSCE. MF explained 24.1% of the PALA in written exams and 25.9% of PALA in CPX/OSCE. Both PALA and MF showed significant differences between written exams and CPX/OSCE in third-year students, whereas those in fourth-year students showed no differences. Educators need to consider MFs that influence the PALA to encourage 'assessment for learning'.

It is a descriptive study for the relationship between appearance management behaviors and mental health of some female college students. We analyzes 433 self-administered questionnaires from March to June 2017 for female students who enrolled in three-year colleges in Seoul and Gyeonggi province, South Korea. The conclusion is as follows. We used IBM SPSS Statistics 22.0(SPSS Inc., Chicago, IL, USA) for the analysis by person's characteristics, t-test and one way ANOVA, multiple regression analyses. The second-year grade shows higher points than the first-year grade in appearance management behaviors and mental health level(p<0.001, p<0.05). In addition, when students has the higher level of the household as the humanities students, they have higher level of mental health level(p<0.001). The most influential factors affecting the mental health level of female college students are domestic economic level and cosmetic management behavioral factors. The level of mental health was higher in the middle and upper group of the domestic economic level. When they do more cosmetic management behavior, they have lower the mental health level. In conclusion, it is deemed necessary for students to attend intensive and sufficient counseling with an academic advisor. The continuous attention through school counseling management services depending on grade, domestic economy level, and cosmetic management behavior is necessary in order to enhance the level of mental health for female students. In addition to that, the college needs to develop individual customized psychology counseling and educational programs through U-mental healthcare service in order to lessen the great pressure of sensitive information and provide mental consultation. The college needs to consider students' characteristics and needs from the results of this study. It is considered that a smart mental healthcare program will be needed to identify mental health of the individual through the systematic approach.

Purpose: The purpose of this study was to investigate patient safety teaching competency of nursing faculty and the extent of teaching patient safety topics in the nursing curriculum. Methods: A national survey was conducted with full-time nursing faculty in 4-year nursing schools. Regional quota sampling method was used. An online survey was sent to 1,028 nursing faculty and 207 of them were completed. Among the 207, we analyzed data from 184 participants. The revised Health Professional Education in Patient Safety Survey was used. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation analysis, and multiple linear regression analyses. Results: The faculty's self-confidence was lower than their perceived importance of patient safety education. The mean score of teaching patient safety was $3.52{\pm}0.67$ out of 5, and the contents were mostly delivered through lectures. The extent of faculty's teaching varied depending on faculty's clinical career, teaching subjects, participation in practicum courses, and previous experience of patient safety education. The significant predictors of the extent of teaching patient safety were the faculty's self-confidence in teaching patient safety (${\beta}=.39$) during clinical practicum, their perceived importance of patient safety education during lectures (${\beta}=.23$), and the teaching subject (${\beta}=.15$). Conclusion: To enhance the competency of nursing faculty for effective patient safety education, a patient safety education program tailored to faculty characteristics should be developed and continuously provided for faculty. In addition, it is necessary to improve patient safety curriculum, strengthen clinical and school linkages, and utilize various education methods in patient safety education.

Background: This study aimed to provide basic data to establish a foundation for efficient operation of the organization by assessing the effects of self-efficacy and job stress (measured by self-efficacy, job demand, and job autonomy) on organizational commitment among clinical dental hygienists. Methods: This was a cross-sectional survey study that used a self-administered questionnaire to collect data. After institutional review board approval, a survey was conducted from January to May 2017, targeting dental hygienists working in dental clinics and hospitals. The final 199 questionnaires were analyzed with PASW 18.0 for Windows (IBM Corp.). The data were analyzed using mean and/or standard deviation t-test, one-way ANOVA, and multiple regression analysis. Results: The means for self-efficacy, job demand, job autonomy, and organizational commitment were $55.94{\pm}9.65$, $26.55{\pm}2.29$, $20.24{\pm}3.88$, and $49.49{\pm}8.39$, respectively. Along with self-efficacy, the other factors of organizational commitment among dental hygienists that were statistically significant included job autonomy, mean salary (2,500~2,990 thousand Korean won [KRW] and ${\geq}3,000$ thousand KRW), and employee welfare (good), which are sub-areas of the surface acting. In other words, it was found that the higher the mean salary, the better the employee welfare, the higher self-efficacy, and the higher the organizational commitment, and the explanatory power of the model was approximately 42.1%. Conclusion: These results suggest that the higher the self-efficacy, job autonomy, mean salary, and employee welfare, the higher the organizational commitment. In order to improve job demand among dental hygienists, it is necessary to establish an effective plan to improve job welfare, self-efficacy, and job autonomy.

Objectives: The purpose of this study was to propose contents of a curriculum and training program for dental hygienists as medical professionals by surveying the opinions of clinical dental hygienists and dental hygiene professors. Methods: The subjects were 192 clinical dental hygienists and 193 dental hygiene professors. They answered questionnaires that consisted of grading each task based on its importance: a) for dental hygiene students to learn, b) to perform autonomously in clinical practice, and c) the expectancy of the task to change when dental hygienists become medical professionals. Data analysis was performed using an independent sample T test to capture differences between clinical dental hygienists and dental hygiene professors. The terms in the answers of open-ended questionnaires were extracted. We used R 3.5.0, R Recommender, and Wordcloud software packages. Results: Calculus removal had the highest scores for dental hygiene students to learn and expectancy to change when dental hygienists become medical professionals. Physiotherapy of temporomandibular disorders (TMD), planning, performing, and assessment of community oral health programs had the lowest scores in autonomy in clinical practice. The dental hygiene professors gave higher scores in most of the tasks for dental hygiene students to learn, autonomy in clinical practice, and expectancy to change, than did clinical dental hygienists. Cardiopulmonary resuscitation (CPR), job ethics, and communication were the most frequently mentioned terms in the training as medical professionals program contents. Conclusions: In the future, it will be necessary to study the curriculum to improve the proficiency of dental hygienists as medical professionals.

This study is a descriptive research to measure the awareness and attitude toward withdrawal of life-sustaining medical treatment (WLSMT) among medical and nursing students. The data collection was conducted between 8 October and 15 November 2018, and the responses of 240 students were analyzed. The analysis results are as follows. More than 95 percent of medical and nursing students said the WLSMT was necessary. The medical students answered that 'patient's will' is important and nursing student answered that 'patient and family's will' is important. The nursing student showed that "family will and decision" was more important than the medical student in deciding to discontinue life care. Based on the results of the study, continuous discussion on the development and application of education programs to form attitudes and awareness of the discontinuation of life-saving treatments based on correct values is needed for prospective medical students and nursing students.
