The impacts that AI and robotics systems can and will have on our everyday lives are already making themselves manifest. However, there is a lack of research on the ethical impacts and means for amelioration regarding AI and robotics within tourism and hospitality. Given the importance of designing technologies that cross national boundaries, and given that the tourism and hospitality industry is fundamentally predicated on multicultural interactions, this is an area of research and application that requires particular attention. Specifically, tourism and hospitality have a range of context-unique stakeholders that need to be accounted for in the salient design of AI systems is to be achieved. This paper adopts a stakeholder approach to develop the conceptual framework to centralize human values in designing and deploying AI and robotics systems in tourism and hospitality. The conceptual framework includes several layers - 'Human-human-AI' interaction level, direct and indirect stakeholders, and the macroenvironment. The ethical issues on each layer are outlined as well as some possible solutions to them. Additionally, the paper develops a research agenda on the topic.

Korea's quarantine response to the novel coronavirus (coronavirus disease 2019 [COVID-19]) pandemic is based on the sacrifice of health professionals, especially public health doctors (PHDs) who were called out first and put in the first place in the country. PHDs performed major quarantine tasks, such as collecting samples from screening clinics and epidemiological investigations, in various parts of the country, including the Daegu area, where the first large-scale COVID-19 confirmed cases in Korea and explosively increased. Because of their position as fixed-term civil servants, however, PHDs' professionalism as doctors was ignored, and they were not properly compensated for their work. They were also exposed to problems such as a high risk of infection, mental suffering, and various human rights violations. We must prepare concrete measures to improve the fundamental treatment of PHDs and protect their human rights in order to prepare for a possible infectious disease pandemic in the future.

Applying human engineering simulation to analyzing work capability and movements of operators during manufacturing is highly demanded. However, difficulty in modeling digital human required for simulation makes engineers to be reluctant to utilize human simulation for their tasks. This paper addresses such problem on human engineering simulation by developing the technology to automatize human modeling with multiple Kinects at different depths. The Kinects enable us to acquire the movements of digital human which are essential data for implementing human engineering simulation. In this paper, we present a system for modeling automation of digital human. Especially, the system provides a way of generating the digital model of workers' movement and position using multiple Kinects which cannot be generated by single Kinect. Lastly, we verify the effects of the developed system in terms of modeling time and accuracy by applying the system to four different scenarios. In conclusion, the proposed system makes it possible to generate the digital human model easily and reduce costs and time for human engineering simulation.

The management of safety at sea is based on a set of internationally accepted regulations and codes, governing or guiding the design and operation of ships. The regulations most directly concerned with human safety and protection of the environment are, in general, agreed internationally through the International Maritime Organization(IMO). IMO has continuously dealt with safety problems and, recognized that the human element is a key factor in both safety and pollution prevention issues(IMO, 2010). This paper proposes a human error analysis methodology which is based on the human error taxonomy and theories (SHELL model, GEMS model and etc.) that were discussed in the IMO guidelines for the investigation of human factors in marine casualties and incidents. In this paper, a cognitive process model, a human error analysis technique and a marine accident causal chains focused on human factors are discussed, and towing vessel collision accidents are analyzed as a case study in order to examine the applicability of the human error analysis technique to marine accidents. Also human errors related to those towing vessel collision accidents and their underlying factors are discussed in detail.

Consumer products are produced on the premise that consumers can use their products safely and effectively no matter how serious human errors they may make. However, different careers and educational experiences of them may induce diverse human errors when they want to use them. In that sense, not a few policies to reduce human errors may show some implications for human error prevention and industrial design of consumer products. In this paper, producers' safety efforts required by Product Liability(PL) Act were reviewed in view of human error prevention, and legal aspects of manufacturers' responsibility for consumer products were discussed in relation to Product Liability Act. Then, principal approaches for them were introduced under the title of System Safety Precedence. After that, major key points for preventing human errors related with consumer products - such as ergonomic design and effective labeling - were discussed with reference to ISO standards. Therefore, it was shown that all the efforts required by PL Act would be correspondent to human error prevention in the whole manufacturing processes if understood by ergonomists. To make a conclusion, it could be said that, for human error prevention, the principle of System Safety Precedence would be indispensable, and that all the efforts for preventing human errors should be systematically organized in Product Safety Management Systems.

The purpose of this study was to investigate the awareness and practices for diet according to the lifestyles of college students in Youngnam region. The data were collected by self-administered questionnaires during May 2007. One hundred-ninety samples were analyzed by SPSS Windows. Frequencies, Cronbach's alpha, factor analysis, cluster analysis, one-way analysis of variance, Duncan's multiple range test and chi-square test were conducted. The results were as follows. Lifestyles were categorized into four factors by factor analysis: popularity-seeking type, body-management-seeking type, convenience-seeking type and healthy-seeking type. In addition, the respondents belonged to one of four groups by cluster analysis: body-management-seeking group, popularity-seeking group, convenience-seeking group, and healthy-seeking group. There were significant differences in perception about individual body images, concern of diet, awareness of diet necessity and knowledge and practices for diet among the four groups. That is, the body-management-seeking group showed the highest levels of concern of diet, awareness of diet necessity and the practice of fasting therapy. Additionally, the healthy-seeking group showed the highest level of practice of exercise therapy.

According to much research on cognitive science, the impact of the scene-context on human visual search in real-world images could be as important as the saliency. Therefore, this study proposed a method of Adaptive Control of Thought-Rational (ACT-R) modeling of visual search in real-world images, based on saliency and scene-context. The modeling method was developed by using the utility system of ACT-R to describe influences of saliency and scene-context in real-world images. Then, the validation of the model was performed, by comparing the data of the model and eye-tracking data from experiments in simple task in which subjects search some targets in indoor bedroom images. Results show that model data was quite well fit with eye-tracking data. In conclusion, the method of modeling human visual search proposed in this study should be used, in order to provide an accurate model of human performance in visual search tasks in real-world images.

IT governance is an integral part of enterprise governance and consists of the leadership, organizational structures, and processes that ensure organization's IT decision making for achieving organizational goal. Most firms have failed to resolve the balance in building IT governance. The challenge is to align IT strategy with business strategy in establishing and implementing effective IT governance. The purpose of this study is to find out the relationship between IT governance implementation factors and IS effectiveness, and the moderating effect of strategic alignment of IS strategy with business strategy on IS effectiveness. IT governance implementation factors consist of IT vendor management, IT human resource management, and IT infrastructure. Strategic alignment was measured as the alignment between business strategic orientation and IS strategic orientation that used in the research of Chan et al.(1997). In the relationship between three IT governance implementation factors and IS effectiveness, the results of multiple regression analyses showed that IT human resource management is an important determinant to influence IS effectiveness. The additional analysis using multiple regression showed that strategic alignment of IS strategy with business strategy has moderated the relationship between IT governance implementation factors and IS effectiveness.
