Various international reports have shown strong proof that socioeconomic and sociodemographic variables are correlated with allergic diseases, yet little is known about how these variables affect Korean adolescents. This study was conducted to identify the socioeconomic and sociodemographic risk factors for allergic diseases of Korean adolescents, and to provide information for preventing and managing such conditions. Data from the 2018 Korean Youth Risk Behavior Survey (KYRBS) of 60,040 adolescents was used for this study. An anonymously administered online survey was conducted to collect information on the dependent variables. The independent variables were asthma, allergic rhinitis and atopic dermatitis. Multivariate logistic regression analysis was performed to analyze the correlations between the dependent variables and the independent variables. Low economic status, living with mother, high education level of parents, high school record, obesity, drinking and smoking were the risk factors for asthma. Low economic status, the place of residence, living with mother, high education level of the parents, gender, high school record, obesity, drinking and smoking were the risk factors for allergic rhinitis. Low economic status, living with mother, high education level of parents, genderhigh school record, obesity and drinking were the risk factors for atopic dermatitis. We found that low socioeconomic status and unhealthy behavior were the risk factor for allergic diseases of Korean adolescents. Balanced economic growth in the community and controlling unhealthy behavior can help reduce the prevalence of allergic diseases.

Recently, drone applications have been expanded not only in the military and security fields but also in daily life such as commercial and sports, and there is also a growing interest in using drone for private security work. This study focuses on the discussion on the use of drones in private security, drones regulation in the related laws such as the Private Security Act and the Aviation Safety Law, and major issues in accepting the Private Security Act. First, it focuses on the scope of private security work as defined by the Private Security Act, focusing on the use of drones as surveillance, information gathering, guidance and warning services, evacuation services, search and related material transport services, respectively. Second, the related laws for the use of drones in private security work include the Private Security Act and the Aviation Safety Act. However, the Private Security Act does not prescribe the current drones and the use of drones is regulated by Aviation Safety Act. Third, it is necessary to adjust the qualifications and authority range of security guards in the Private Security Act, to accept the drones as a type of security equipment, and to consider how countermeasures against threat types using drones should be accepted in the Private Security Act.

In the study, the moral sensitivity, moral distress, and biomedical ethics awareness levels of hospital nurses are examined, and the mediating effect of biomedical ethics awareness in the relationship between moral sensitivity and moral distress is verified. As the study subjects, 153 hospital nurses were selected from both university hospitals and general hospitals in S city and J city. Using the SPSS WIN 21.0 system, data analysis was conducted via t-tests, the Sheffe test, correlation analysis, multiple regression analyses, Sobel test. The average level of moral sensitivity experienced by the hospital nurses was 4.70(out of 7), moral distress was 62.80(out of 336), and biomedical ethics awareness was 2.21(out of 4). Moral distress had a static correlation with moral sensitivity and biochemical ethics awareness, and moral sensitivity had a static correlation with biomedical ethics awareness. Finally, biomedical ethics awareness showed a partial mediating effect in the relationship between moral sensitivity and moral distress. It is important to develop a biomedical ethics education program that can help hospital nurses to resolve moral issues, thereby improving moral sensitivity and diminishing their moral distress.

This study was conducted to identify the subjective happiness and self-esteem of nursing students and how these variables affect clinical practice stress. Participants consisted of 199 nursing students who were in the third and fourth years who had experienced clinical practice at two nursing universities located in Gyeongnam, and agreed to the survey. Data were collected using questionnaires from June 15 to August 29, 2020. Collected data were analyzed using the SPSS 22.0 statistics program with descriptive statistics, an independent t-test, ANOVA, Scheffe's test, and multiple regression. The mean score for subjective happiness was 4.87 (out of 7), the mean for self-esteem was 3.84 (out of 5), and clinical practice stress was 2.77 (out of 5). The significant predictors of the clinical practice stress were gender, major satisfaction and self-esteem, and the explanatory power of variance was 14.1%. Therefore, we need differentiated clinical practice stress reduction programs according to gender and various strategies that can enhance major satisfaction in order to reduce the clinical practice stress of nursing students.

In recent years, public bicycle systems are widely spread over the world according to the development of ICT technology. Since the public bicycle systems in large cities need to secure both publicity and convenience for citizens, analysis of various their issues from introduction to operation is required. In addition, it is also necessary to prepare for various scenarios for coexistence with the PM business, which is recently in the spotlight as a last mile means and normally managed privately. This paper introduces modeling and simulation for efficient operations of public bicycle systems. In particular, the proposed method was developed in a form that can be easily used in other cities by modeling the general structure and behavior of the public bicycle system, and it was developed to facilitate modification and expansion of the future model with a component-based model configuration. This paper provides a case study of the propose method, which is the public bicycle simulation in Sejong City. The simulation results were derived by applying the data from the public bicycle system of Sejong City, and they were verified with the associated real data of Sejong City. Using the verified model, it is expected that it can be used as a tool to design and analyze various services on the public bicycle systems, which were especially suitable for Sejong City.

The purpose of this study is to investigate the influence of teacher-librarians' autonomy support on the school library users' satisfaction and continuance intention. Based on SDT(self-determination theory), it focuses on the mediating effect of BPN(basic psychological needs) between the autonomy supports and the satisfaction of the school library users. A survey was administered to 331 middle school students and the research model was examined by using regression analysis and Hayes' parallel multiple mediator model. The findings show that the teacher-librarians' support for autonomy directly and indirectly has a positive effect on the students' satisfaction with the school library, and perceived autonomy and competence among the sub-factors of basic psychological needs are found to have a significant mediating effect between the support of the librarian's autonomy and satisfaction with the school library. In addition, students' satisfaction with the school library shows a significant effect on the continuance intention. This study is meaningful in that it presents the role of teacher-librarians as a factor affecting students' motivation to use school libraries and provides implications for revitalizing school libraries.

Libraries are experiencing numerous modifications to multifunctional spaces in response to the declaration of WHO pandemic. Most libraries throughout the globe have reported their closures, including national libraries in every country, and most established facing services have been transformed to untact services. However, the breadth of the service varies by local autonomous entity and library, making it difficult for librarians to act according to their conviction, and also users are feeling inconvenienced. As a result, this study used a user perception survey to determine the extent of non-face-to-face services in the library and to suggest the direction of operation of non-face-to-face services in a pandemic condition. To that purpose, beginning February 12, 2020, an online survey of library customers in 37 public libraries was performed for about three weeks, and the 117 replies were examined using the SPSS statistics tool to perform frequency analysis, regression analysis, correlation analysis, and reliability analysis. By the survey and data survey results, it was recommended that library services be re-established in the direction of non-face-to-face library service operation, that library non-face-to-face services be expanded, that user education be conducted, that non-face-to-face services be promoted, and that user opinions be collected.

Earthquakes have occurred owing to movements on a fault since several billion years ago. Research on the relationship between earthquakes and groundwater began in the 1960s in the United States, but related works, including hydrogeochemistry research, only began in the 2010s in South Korea. In this study, domestic studies on the relationship between earthquakes and groundwater until 2021 were collected from the Web of Science and characterized by subject area (groundwater level, hydrogeochemistry, combination of the two, and others). The results showed that the number of published articles per year was positively correlated with the 2011 Tohoku earthquake, 2016 Gyeongju earthquake, and 2017 Pohang earthquake, with the maximum numbers observed in 2011, 2018, 2019, and 2020. Most studies on the relationship between earthquakes and groundwater level addressed groundwater level fluctuations in the duration of the subject earthquake, with little consideration of the precursors. Groundwater level monitoring data, as well as hydrogeochemical information and microbial communities, may contribute to a more detailed understanding of groundwater flow and chemical reactions in bedrock caused by earthquakes. Therefore, the establishment of a national groundwater monitoring network for seismic monitoring and prediction is required.
