In this paper, we propose a novel recommendation model based on Doc2vec using search keywords and product details. Until now, a lot of prior studies on recommender systems have proposed collaborative filtering (CF) as the main algorithm for recommendation, which uses only structured input data such as customers' purchase history or ratings. However, the use of unstructured data like online customer review in CF may lead to better recommendation. Under this background, we propose to use search keyword data and product detail information, which are seldom used in previous studies, for product recommendation. The proposed model makes recommendation by using CF which simultaneously considers ratings, search keywords and detailed information of the products purchased by customers. To extract quantitative patterns from these unstructured data, Doc2vec is applied. As a result of the experiment, the proposed model was found to outperform the conventional recommendation model. In addition, it was confirmed that search keywords and product details had a significant effect on recommendation. This study has academic significance in that it tries to apply the customers' online behavior information to the recommendation system and that it mitigates the cold start problem, which is one of the critical limitations of CF.

This study aimed to provide the basic data for the development of a simulation training program for new infectious diseases by analyzing the knowledge and educational needs of 119 paramedics regarding COVID-19 infection control. Data was obtained through a structured questionnaire survey of 186 paramedics from November 15th to 30th 2020. The study showed that 98 of the 119 paramedic subjects (52.7%) had not been educated regarding COVID-19. The knowledge level was 18.21±1.98 out of 25 points, with environmental control securing the lowest correct answers. The highest need for education was in the areas of prevention of transmission and spread, and employee safety control. The total average for educational needs was 3.81±.28 (4 point scale) with the highest educational need in the area of prevention of the spread and dispersion of the disease and employee safety management. There was a statistically significant difference in the knowledge of the general characteristics according to gender (t=-1.999, p=.047) and the educational demand was related to career (t=-1.999, p=.047) and, education levels (t=2.336, p=.021). Accordingly, it is necessary to plan a new infectious disease simulation education program that addresses the low-scoring areas and items with high educational needs which include the propagation path and spread prevention, environmental management, and employee safety management as per the findings of this study.

This is a descriptive research study on industrial workers to understand the effects of drinking patterns, job stress, and leisure satisfaction on their health promotion behavior. Subjects of the survey were 207 workers undergoing health checkups at three hospitals in U metropolitan city. Data was collected from November 1, 2019, to November 30, 2019, through a structured questionnaire. The IBM SPSS 24.0 program was used to analyze data. The subjects' drinking frequency was 2 to 3 times a week, (36.3%), and the motive was a social gathering (54.6%). The averages were 62.46±5.59 for job stress, 30.29±6.39 leisure satisfaction, 125.64±8.77 for health promotion behaviors, which was higher than the median. Health promotion behavior was found to have a statistically significant positive correlation with job stress (r=.227, p<.001) and leisure satisfaction (r=.542, p<.001). A multiple regression analysis of the factors affecting health-promoting behavior showed that this is affected by drinking patterns, job stress, and leisure with an explanatory power of 29.7%. Based on this study, continuous support is needed for industrial workers to relieve their social gathering and job stress through leisure activities, not drinking, and we expect them to improve their quality of life through a healthy lifestyle and health promotion behavior.

Objectives: This research aimed to identify the level of perception, knowledge, preventive behavior, and factors affecting preventive behavior of patients with asthma and chronic obstructive pulmonary disease against particulate matter. Methods: This research was a descriptive survey research, and the subjects were chronic pulmonary disease patients over the age of 19 and under 80 who visited a university hospital in Daegu City. Data was collected by convenience sampling through structured self-administered questionnaire survey from December 2019 to January 2020, and a total of 212 copies were used for analysis. Results: Out of 212 total subjects, 112 were asthma patients (52.8%) and 100 were chronic obstructive pulmonary disease patients (47.2%). The average score (out of 10) of perception, knowledge and preventive behavior of patients with asthma for particulate matter was 7.92, 6.99, and 7.10, respectively, while those with chronic obstructive pulmonary disease scored 7.72, 6.24, and 6.80, respectively. The knowledge score was significantly higher in patients with asthma than those with chronic obstructive pulmonary disease (p=0.007). Factors affecting particulate matter preventive behavior were perception score, knowledge score, and age for asthma patients, and perception score for chronic obstructive pulmonary disease patients. Conclusions: As a result of the above, the factors relate to the preventive behavior of patients with asthma and chronic obstructive pulmonary disease were perception score, knowledge score, and age for asthma, and perception score for chronic obstructive pulmonary disease. Raising the level of particulate matter preventive behavior can prevent the deterioration of chronic pulmonary diseases caused by particulate matter, so the development of arbitration programs considering the characteristics of the patients according to the disease and continuous and repetitive education are required.

The purpose of this descriptive correlational study was to explore the effect of knowledge of evidence-based practice (K-EBP) and organizational culture on the innovation behavior of university librarians in South Korea. The structured survey questionnaire consisted of four sections and 60 items. The four sections were concerned with K-EBP, organizational culture, innovation behavior, and EBP-related activities and demographic. The respondents were librarians working in 101 university libraries in South Korea. The results of this study were as follows. First, K-EBP indicated that the respondents had excellent practical skills, but their ability to appraise critically, apply knowledge and to conduct research was weak. Second, the questionnaire scores for K-EBP were significantly positively correlated with those for organizational culture and innovation behavior. Higher K-EBP scores corresponded to higher scores for relation-, innovation-, and task-oriented organizational culture. Third, K-EBP outcomes differed significantly by age group, education level, employment type, job title/seniority, reading of academic journal articles, and attendance at conferences. Organizational culture differed significantly with age. Innovation differed significantly with both age and conference attendance. Fourth, in the hierarchical multiple regression analysis, factors predicting K-EBP scores were education level and reading academic journals. Fifth, the multiple regression analysis identifying factors predicting innovation revealed statistically significant regression coefficients for overall K-EBP and for innovation- and hierarchy-oriented organizational culture. The regression coefficient for perception of a hierarchy-oriented organizational culture was negative. To promote innovation behavior of librarians, we need to foster an innovative organizational culture characterized by communication and cooperation, and improve the ability of librarians to engage in EBP. Educational programs that promote librarian engagement in research-related activities are needed.

The purpose of this study was to conduct interviews with librarians who have experience in establishing local authority data by participating in the national authority sharing system of the National Library of Korea and to understand librarians' recognition and support for the joint utilization of national authority data. For this purpose, a total of 10 librarians who participated in the national authority sharing system project were interviewed by telephone using semi-structured questionnaires. Through this, it was possible to investigate the benefits, difficulties, utilization plans, revision plans of headings, and opinions on necessary support. The results of this study showed that the participants recognized that the joint utilization of national authority data provides the basis for the authority work of the local library and brings about the efficiency of the authority work, but they recognized the difficulty of modifying, selecting, creating new data, lacking knowledge, and lacking support system. The necessary support for the joint utilization of national authority data was provided with education and manuals related to authority, provision of rules related to authority that fully consider the position of the institution, budget and manpower support for system development and maintenance, establishment of communication channel and council, system and data advancement, and incentive to participating libraries. Based on the results of the study, the method and direction for the future operation of the joint utilization of national authority data were presented.

This study examined the correlation between safety practices and safety knowledge, safety awareness and safety efficacy, and the factors influencing the safety practices of in-home child-care providers. The participants were 199 in-home child-care providers who worked at two cities in G province. Using a structured-questionnaire, the data were collected from December 2019 to January 2020. The data were analyzed using the IMB/SPSS 25.0 program. The collected data were analyzed using descriptive statistics (frequency, percent, mean, and SD), a t-test, ANOVA, Scheff test, Pearson Correlation Coefficient, and multiple regression. The mean score for safety knowledge, safety awareness, safety efficacy, and safety practices were 0.64 (SD, 0.09), 1.92 (SD, 0.37), 4.18 (SD, 0.51), and 2.55 (SD, 0.36), respectively. Safety practices were positively correlated with the safety knowledge (r=.14, p=.042), safety efficacy (r=.43, p<.001), and sub-factors of safety efficacy, self-regulation (r=.32, p<.001), enlisting social support (r=.40, p<.001), and controlling the environment (r=.39, p<.001). Enlisting social support and controlling the environment, sub-factors of safety efficacy were influenced safety practices significantly and explained 20.0% of the variance. Based on these findings, it will be necessary to develop a program that can enhance their safety efficacy for safety practices of in-home child-care providers.
