Real patients as co-debriefers in simulation-based education: An exploratory study

This thesis explores and describes the experiences and perspectives of three different roles within a patient-centred, healthcare simulation-based education session for the continuing professional development of new graduate nurses. The experiences examined are those of the session’s co-debriefers, who include a mix of patient family partners and clinical educators, and the learners, who are new graduate nurses. The study uses mixed methods but primarily takes the form of a basic qualitative descriptive study and meets the requirements of patient-oriented research. Participants included 44 new graduate nurses, six clinical educators, and two patient family partners. Survey and interview analysis are developed around three main themes: Findings specific to simulation and co-debriefing, Beliefs surrounding patient- and family-centred care and the inclusion of patient family partners, and Relationships. Implications for practice and future research are recommended

Nitrogen Metabolism of the Dairy Cow in Relation to Voluntary Feed Intake and Milk Production on Grass Silage Diets

1. Experiments were conducted to investigate nitrogen metabolism of the dairy cow in relation to the control of the voluntary intake of grass silage and its utilization for milk production. Two aspects were considered: the effects of ammonia absorption from the rumen and the effects of changes in the post-ruminal supply of proteins and amino acids. In all experiments, dairy cows were given ad libitum access to grass silage and a fixed level of supplement based on barley and, where necessary, soyabean meal to give a total dietary CP concentration of 140-150 g/kg DM

VEHICLE SECURING SAFETY ASSESSMENTS OF A KOREAN COASTAL CAR FERRY ACCORDING TO ACCELERATION PREDICTION APPROACHES

The capsize and subsequent sinking of a coastal car ferry occurred along the Korean coast, resulting in hundreds of casualties. The rapid course change of the ship might have forced improperly secured cargoes to rush to one side and accelerated the capsizing event. This paper provides a comparative study of vehicle securing safety assessments composed of evaluations of the external inertia forces and lashing strengths for a car and a truck. The external inertia forces were evaluated based on the IMO CSS (CSS approach) and rule-based maximum motion angles (RULE approach). Being a car ferry as a target ship, the sea states were collected along the most frequent seagoing routes of the target ship. Frequency domain seakeeping analyses (FSA approach) were carried out and then the long-term motion components were derived using the collected sea state data. The long-term motion components were put forward based on time domain seakeeping analyses (TSA approach). The TSA approach estimated the most optimistic external forces, while the CSS approach provided the most conservative external forces. Assuming the vehicles were secured symmetrically with four steel wires, the lashing strengths were derived. More numbers of lashing cables were required for the heavy vehicles when the CSS approach was applied, while other approaches predicted sufficient lashing strengths compared to exerted forces

Monitoring Water Resource Changes Using Multi-temporal Landsat Imagery Taken in Changnyeong, South Korea

AbstractMonitoring water resource changes is essential in water resources management and in flood or drought prevention. This research aims to monitor water resource changes using the multi-temporal Landsat imagery taken in December 2006 and 2014 through the following steps. First, the multiple NDWI (Normalized Difference Water Index) images are generated from the Landsat images. Next, multiple water resources such as the Nakdong River and the Dalchang reservoir are extracted from each NDWI image. Finally, the areas of the Nakdong River and the Dalchang reservoir in each NDWI image are measured to assess the water resource changes in the study area. The statistical results show that the Nakdong River had significantly increased its water storage capacity between 2006 and 2014, while the Dalchang reservoir had the constant area during the same period

A multilevel framework for AI governance

To realize the potential benefits and mitigate potential risks of AI, it is necessary to develop a framework of governance that conforms to ethics and fundamental human values. Although several organizations have issued guidelines and ethical frameworks for trustworthy AI, without a mediating governance structure, these ethical principles will not translate into practice. In this paper, we propose a multilevel governance approach that involves three groups of interdependent stakeholders: governments, corporations, and citizens. We examine their interrelationships through dimensions of trust, such as competence, integrity, and benevolence. The levels of governance combined with the dimensions of trust in AI provide practical insights that can be used to further enhance user experiences and inform public policy related to AI.Comment: This paper has been accepted for publication and is forthcoming in The Global and Digital Governance Handbook.

A database for propagation models

The NASA Propagation Program supports academic research that models various propagation phenomena in the space research frequency bands. NASA supports such research via school and institutions prominent in the field. The products of such efforts are particularly useful for researchers in the field of propagation phenomena and telecommunications systems engineers. The systems engineer usually needs a few propagation parameter values for a system design. Published literature on the subject, such as the Cunsultative Committee for International Radio (CCIR) publications, may help somewhat, but often times, the parameter values given in such publications use a particular set of conditions which may not quite include the requirements of the system design. The systems engineer must resort to programming the propagation phenomena model of interest and to obtain the parameter values to be used in the project. Furthermore, the researcher in the propagation field must then program the propagation models either to substantiate the model or to generate a new model. The researcher or the systems engineer must either be a skillful computer programmer or hire a programmer, which of course increases the cost of the effort. An increase in cost due to the inevitable programming effort may seem particularly inappropriate if the data generated by the experiment is to be used to substantiate the already well-established models, or a slight variation thereof. To help researchers and the systems engineers, it was recommended by the participants of NASA Propagation Experimenters (NAPEX) 15 held in London, Ontario, Canada on 28-29 June 1991, that propagation software should be constructed which will contain models and prediction methods of most propagation phenomenon. Moreover, the software should be flexible enough for the user to make slight changes to the models without expending a substantial effort in programming

An Analysis of restaurant food safety violations: human factors, non-human factors, and food-borne illness

An estimated 76 million food-borne illnesses occur in the United States each year, causing 325,000 hospitalizations and 5,000 deaths, according to the U.S. Food and Drug Administration. Food safety is an increasingly important topic to governmental food regulators, not only in trying to reduce the number of illnesses from contaminated food. Governmental regulators also are becoming aware of the vulnerability of the food supply chain as a target for bioterrorism. Recommendations have been developed to protect the U. S. food supply from terrorism, but little of the research and recommendations relate to the food-service level. Eighty percent of reported cases of food-borne disease occur in food-service establishments. The results of health inspections over six months in the Las Vegas, NV, area were analyzed to determine whether violations were due to human or non-human factors. Human factors were defined as cross-contamination, time and temperature abuse, and poor personal hygiene. The non-human factors were environmental violations, such as poor maintenance and lack of facilities. The human factors can be improved by developing proper training systems and monitoring food safety practices by supervisors. The data show that human factors were responsible for 62.8% of violations cited by health inspectors. Upon reinspection, 97.4% of food-service establishments that had received a grade of less than A had corrected the violations and received an A grade. This shows that effective education can dramatically improve violations due to human factors. This establishes a significant foundation to establish proper food safety training systems to prevent food-borne illnesses in the food-service industry
