Objectives: The purpose of this study was to examine the influence of human rights sensitivity and nursing work environment on workplace bullying victimization among nurses in small- and medium-sized hospitals. Methods: The participants were 255 nurses from 5 general hospitals in Busan. A dataset was collected using a structured self-reporting questionnaire during the month of July 2018. The data were analyzed with SPSS WIN 23.0 software (IBM Corp., Armonk, NY, USA) using independent t-test, one-way analysis of variance, Pearson's correlation coefficient, and multiple regression analysis. Results: Nursing work environment showed negative correlation with workplace bullying victimization. Being a witness to bullying, organizational support, head nurse's leadership, and relationships with peers were found to influence workplace bullying victimization, and these 4 variables explained 37% of workplace bullying victimization. Conclusions: Formal procedures for cases of bullying and improvements in the leadership of head nurses and peer relationships are crucial to reducing workplace bullying victimization among nurses in small- and medium-sized hospitals. Hospital executives' efforts to provide sufficient physical and human resources for nursing services and to improve the welfare of nurses are also needed.

This study aims to develop a human activity recognition (HAR) system as a Deep-Learning (DL) classification model, distinguishing various human activities. We solely rely on the signals from a wristband accelerometer worn by a person for the user's convenience. 3-axis sequential acceleration signal data are gathered within a predefined time-window-slice, and they are used as input to the classification system. We are particularly interested in developing a Deep-Learning model that can outperform conventional machine learning classification performance. A total of 13 activities based on the laboratory experiments' data are used for the initial performance comparison. We have improved classification performance using the Convolutional Neural Network (CNN) combined with an auto-encoder feature reduction and parameter tuning. With various publically available HAR datasets, we could also achieve significant improvement in HAR classification. Our CNN model is also compared against Recurrent-Neural-Network(RNN) with Long Short-Term Memory(LSTM) to demonstrate its superiority. Noticeably, our model could distinguish both general activities and near-identical activities such as sitting down on the chair and floor, with almost perfect classification accuracy.

Advancements in technology and the proliferation of digital services have highlighted the importance of luxury brands in service environments. Based on the social exchange theory, this study investigated the interaction between customers and luxury brands in a traditional offline service encounter and a digital online service encounter. The interaction area was classified into three parts: human-human, human-digital, and human-physical environments. We qualitatively investigated the practitioners' working experiences with luxury brands. The study determined that both online and offline service encounter interactions between luxury brands and customers have become diverse. First, forming a special relationship with customers and frontline employees in traditional service encounters is important. Second, luxury brands should focus on the interaction among customers. Third, various digital tools should be considered to provide information about the brand to customers. Fourth, the exclusive benefits of offline service encounters should be maximized to stimulate positive experiences. The findings provide valuable insight to scholars and marketers on the new interaction phase between customers and luxury brands in the digital age.

Hazardous wastes released into the general environment are of concern to the public and to public health authorities. In response to this concern, the Comprehensive Environmental Response, Compensation, and Liability Act, as amended (commonly called Superfund), was enacted in 1980 to provide a framework for environmental, public health, and legal actions concerning uncontrolled releases of hazardous substances. The Agency for Toxic Substances and Disease Registry (ATSDR) was created by Superfund to address the public health issues of hazardous wastes in the community environment. Two key Agency programs, Public Health Assessments and Toxicological Profiles, are designed to assess the risk to human health of exposures to hazardous substances that migrate from waste sites or through emergency releases (e.g., chemical spills). The Agency's public health assessment is a structured process that permits ATSDR to identify which waste sites or other point sources require traditional public health actions (e.g.. human exposure studies, health studies, registries, health surveillance, health advisories). The ATSDR qualitative public health assessment complements the U.S. Environmental Protection Agency's quantitative risk assessment. For Superfund purposes, both assessments are sitespecific. ATSDR's toxicological profiles are prepared for priority hazardous substances found most frequently at Superfund sites. Each profile presents the current toxicologic and human health effects information about the substance being profiled. Each profile also contains Minimal Risk Levels (MRLs), a type of risk assessment value. This paper covers ATSDR's experience in conducting public health assessments and developing MRLs, and it relates this experience to recommendations on how to improve chemical risk assessments.

This cross-sectional design study was undertaken to determine the factors associated with suicidal ideation in human immunodeficiency virus (HIV)-infected older adults. Data from a city-wide representative sample collected by the Seoul Metropolitan Government were used. The cross-sectional survey was conducted between February and March 2013. Participants selected and included in the analysis were HIV-infected adults living in Seoul, and aged 50 years and older. The overall adjusted model showed that being unemployed (adjusted odds ratio [aOR], 3.34; 95% confidence interval [CI], 1.16-9.57), a history of depression treatment (aOR, 4.61; 95% CI, 1.02-20.66), perceived belongingness (aOR, 0.63; 95% CI, 0.41-0.99), and psychological functioning (aOR, 0.85; 95% CI, 0.73-0.99) were significantly related to suicidal ideation. Psychosocial features were found to be strongly associated with suicidal ideation among HIV-infected older adults. The findings could be useful for HIV nursing consultants to identify HIV-infected older adults who are vulnerable to suicidal ideation. Comprehensive mental health services should be provided as coping resources for HIV-infected older adults who have suicidal ideation.

In recent years, micro-blogging services such as 'Twitter' and 'Me2day' have rapidly become major social networking services. However, it is difficult to grasp the relationship between a user and his/her friends in these micro-blogging services because they simply list messages between them in chronological order. In this paper, we propose a visual analytics system that can help the user intuitively understand relationships with their friends on micro-blogging services by enabling them to analyze the messages quantitatively, qualitatively and temporally. In the visual analytics system, we also present a tool to provide the user with valuable advices after classifying the changing relation patterns with his/her friends, which in turn contributes to improving relationships with friends. The proposed system was successfully implemented as smartphone applications to show its potential to be a tool for analyses and improvement of social relations in micro-blogging services.

In recent years, Hericium erinaceus became famous for comsumer because it contains some materials to assist in human health. This study was carried out to find the difference of occurring pattern of H. erinaceus by pinheading induction methods. Harvest period of T1, T2 treatments were longer than T3~T6. All treatments fresh weights were not significantly different, but T3, T6 treatments's dry weight in 2nd flush were lower than others. T5 treatment's 2nd flush's regeneration rate was the highest than others and looks best quality. Therefore, it is suggested that pinheading induction method would be changed not T1, T2 treatment which were used some farm as Pluerotus ostreatus cultivation, but to scratch surface method which is T5 treatment for cultivation of high quality H. erinaceus.

The purposes of this study which was conducted by applying three projection formulae to the data from admission quota for paramedic of the Ministry of Education & Human Resources Development the number of ambulances the number of emergency medical centers of the Ministry of Health & Welfare and rate of successful candidates of annual report of the National Health Personnel Licensing Examination Board were to find out demand and supply of paramedic from 2002 to 2045 and to expand scope of practice of paramedic in Korea. The conclusions from this study were summarized as follows; (1) The simple formulae derived from the projection formula of the Economic Planning Board were applied under the present Emergency Medical Services Act including qualifying over 3-years experienced EMT-Basic for paramedic examinee, stationing paramedic or EMT-Basic or physician or nurse per ambulance, stationing paramedic or EMT-Basic per emergency medical center and under the amended Emergency Medical Services Act including qualifying only paramedic graduate for paramedic examinee, stationing 4.5 paramedics per ambulance, stationing 10 to 2 paramedics per emergency medical center. (2) It was estimated that on the American basis of 5.6 EMTs per 10,000 in 1996, the number of paramedics under the present act will reach the basis before 2020, the number of paramedics under the amended act will reach the basis about 2040. (3) It was estimated that on the basis of 22,000 paramedics demanded from the number of ambulances, the number of emergency medical centers in 2001, the number of paramedics under the present act will reach the basis before 2015, the number of paramedics under the amended act will reach the basis about 2030. (4) There was relationship between requirements for emergency medical centers scope of practice of paramedic in the act and demand-supply of paramedic, this necessitates surveys, studies, amendment of the act, legalization for expanded scope of practice of paramedic including EMD, instructor, teacher of safety. (5) This study which includes only expanded scope of practice of paramedic and projection for paramedic in the act needs complementary studies such as decision-making process in health manpower policy and so on.

Semantic service can be defined as the service providing search API or reasoning API based on ontology and Web Services. It performs a pre-defined task by exploiting URI, classes, and properties. This study introduces a semantic service composition method based on a semantic broker referring ontology and management information of semantic services stored in a semantic service manager with requirements of the user. The requirements consist of input instances, an output class, a visualization type, semantic service names, and property names. This composition method provides dynamically generated semantic service pipelines including composit semantic services. The user can execute the pipelines provided by the semantic broker to find a meaningful semantic pipeline. After all, this study contributes to develop a system supporting human service planners who want to find composit semantic services among distributed semantic services.

Given the extensive role of IS in everyday life and the increasing presence of women in IS users, understanding gender differences in individual technology continuance usage decisions is an important issue. Nevertheless, much of the large body of research on gender differences has just examined mean differences between women and men in terms of abilities, usage habit, and traits. Even though lots of psychology studies have shown that women, more than men, were influenced by affective factors, gender-affection-continuance use linkage has not been examined in the context of on-line shopping services. Therefore, the primary purpose of this paper is to seek to examine gender differences in terms of influence of affective factor in the context of IS continuance use. Meanwhile, IS continuance has been an important subject of study in the IT research area. To date, to explain why and how users are motivated to continue to use on-line shopping services, lots of theory-based research such as expectation-confirmation model (ECM) has been proposed. In particular, various affective factors have been proposed to explain continuance use of on-line shopping services recently. Affective factors have been regarded as essential factors for increasing relational strength and satisfaction. Several affective factors have been studied by prior IS adoption and continuance studies. Among them are enjoyment and anxiety. In IS continuance research, positive affect has been commonly and narrowly conceptualized and measured as the enjoyment which a person derives from using computers. Hence, in this study, we introduced intimacy factor, which was conceptually related to the quality of interactions and relationships in previous research. It also has been regarded as essential factors for strengthening human relationships. As a result, we have observed gender effect while examining intimacy-continuance bond. As expected based on the previous literatures, women seem to be more sensitive in affective factors. The contribution point here is that we find evidence in the context of on-line shopping services.
