Operation of human-centered robot, in general, facilitates the creation of new process that may potentially harm the human operators. Design of safety-guaranteed operation of human-centered robots is, therefore, important since it determines the ultimate outcomes of operations involving safety of human operators. This study discusses the application of geometric tolerance and head injury criteria to safety assessment of human-centered robotic operations. Examples show that extending "Work Area" has more significant effect on the uncertainty in safety than extending the system range in the presence of velocity control.

Purpose: With the popularity of artificial intelligence (AI) in the service industry and occurrence ofservice failures in AI-based services, understanding human-robot interaction issues in service failure situations is especially important. Some issues which deserve further empirical investigation are whether consumers can develop the same tolerance for chatbots after service failure as they have for human agents, and the relationship between agent type and tolerance is mediated by the mechanisms of perceived warmth and perceived competence. Research Design, Data, and Methodology: This research experimentally collected and analyzed data from 119 university students who had experienced chatbots service failures. Differences in tolerance towards human agents and chatbots after experiencing service failures were explored, with a further examination of the mediating pathways between this relationship via perceived warmth and perceived competence. Results: Consumers are more tolerant ofservice failure with chatbots compared to service failure with human agents. Significant mediation of the relationship between service agent and service failure tolerance by perceived competence, while perceived warmth has no significant mediating effect. Conclusions: This research enhances our understanding of AI-assisted services, human-computer interaction, improves the service functionality of existing smart devices, and deepens the understanding of the relationship between consumer responses and behaviors.

This study was conducted to investigate the thermoregulatory behavior of young males in terms of self-identified thermal tolerance. We recruited 436 male students from Seoul ($24.0{\pm}4.6yr$ in age, $175.3{\pm}5.5cm$ in height, $70.1{\pm}10.6kg$ in body mass, and $23.0{\pm}2.7$ in BMI) in accordance with four types of self-identified thermal tolerance: 1) tolerable of both cold and heat, BCH (N=15); 2) heat tolerable only, HTO (N=118); 3) cold tolerable only, CTO (N=162); and 4) neither cold nor heat tolerable, NCH (N=141). The questionnaire consisted of 55 questions regarding preference to cold or heat environment, seasonal thermoregulatory behaviors including clothing habits, seasonal sleeping environments, health care/physical fitness, and anthropometric items. The results showed that: 1) BCH preferred less auxiliary heating devices, gloves/hats, or thermal underwear in winter and had very few experiences with cold/heat injuries or catching a cold, whereas NCH showed the opposite behavior and experiences as BCH; 2) thermoregulatory behaviors were not symmetrical between summer and winter. Most male students preferred cold beverage/foods to using cooling devices to lower body temperature in summer, whereas auxiliary heating devices were preferred to warm beverage/foods to maintain body temperature in winter; 3) thermoregulatory behaviors of NCH had more items in common with HTO than CTO, while the behaviors of BCH were more closely related to CTO than the behaviors of BCH were more closely related to CTO than HTO. Overall, we confirmed that thermoregulatory behaviors were apparently classified by self-identified thermal tolerance, and such behaviors could be adjusted by improving cold or heat tolerance.

It was measured the energy expenditure in each season, the cold tolerance in winter and the heat tolerance in summer. Farmers' adaptability to the change of environment was compared with those of city-dwellers such as indoor workers and street cleaners to determine the effect of living environment, especially living temperature, on the health of human body. It turned out that farmers had experienced wide range of temperature that was higher in summer and lower in winter than indoor workers. Farmers and street cleaners showed seasonal adaptation in energy expenditure, which was high in winter and low in summer. However, indoor workers did not show seasonal changes. Energy expenditure had an inverse correlation with the temperature in work place where subjects spend the longer time in a day except in female indoor workers in Seoul. And It was proved that farmers and street cleaners had stronger cold tolerance and heat tolerance than indoor workers.

Transplantation would be the only way to cure the end-stage organ failure involving heart, lung, liver, kidney and pancreas. The replacement of the parts of the body damaged to lose its function or lost to trauma must be a dream of human-being. Human history is replete with chimeras, from sphinxes to mermaids, making one wonder if the ancients might actually have dreamed of what now is called 'xenotransplantation'. In the 20th century, the transplantation of organs and tissues to cure disease has become a clinical reality. The development in the fields of surgical techniques, physiology and immunology attributed to the successful transplantation in human. In the center of the successful transplantation lies the progress in understanding the cellular and molecular biology of immune system which led to the development of immunosuppressive drugs and the invention of the concept of immunological tolerance. The mandatory side effects of immunosuppressive drugs including infection and cancer forced us to search alternative approaches along with the development of new immunosuppressive agents. Among the alternative approaches, the induction of a state of immunologic tolerance would be the most promising and the most generic applicability as a future therapy. Recent reports documenting long-term graft survival without immunosuppression suggest that tolerance-based therapies may become a clinical reality. Last year, we saw the epoch making success of overcoming hyperacute rejection in porcine to primate xenotransplantation which will lead porcine to human xenotransplantation to clinical reality. In this review, I dare to summarize the development of transplantation immunology from the perspective of history.

We analyzed the effects of regular Jjimjilbang(Korean sauna) exposure on the heat tolerance in young and old females. Subjects were young(n=7) and old(n=7) females who never had a bath in Jjimjilbang for last year. Jjimjilbang training group took a bath in Jjimjilbang once a week 19 times. Jjimjibang expsure was limited three times per day, Jjimjil were taken free way. To prove the effects of the heat tolerance, Subjects were exposed to hot and humid air$(40.0{\pm}0.5^{\circ}C,\;60{\pm}5%RH)$. In the condition, subjects were taken a foot bathing$(40.0{\pm}0.5^{\circ}C)$ and simulated for 30 min., and rectal temperature, skin temperatures, clothing microclimate, blood pressure, total body weight loss, local sweat and subjective sensation were measured. The results are as follow: Rectal temperature, skin temperatures, clothing microclimate, total body weight and subjective thermal comfort sensation were decreased gradually(p<.001). Local sweat of upper arm was decreased(p<.01). In conclusion. the regular Jjimjilbang exposure has positive effects upon improvement in regulation of body temperature, especially in heat tolerance.

This study investigated elderly winter wearing habits and self-identified thermal tolerance in order to compare differences between older males and older females. We surveyed 269 participants: 119 males (age $76.9{\pm}5.9yr$) and 150 females (age $76.1{\pm}5.7yr$). Thirty one questionnaires were used: Self-identified cold and heat tolerance, clothing behavior, lifestyles related to the cold and health care, etc. High percentage of respondents (both males and females) felt vulnerable to the cold. The total number of outdoor clothes were $9.6{\pm}1.6$ and $10.6{\pm}1.6$ in males and females, respectively (p<.05). Wearing frequencies for thermal underwear were 84.0% and 82.4% in males and females, respectively. The using percentage of auxiliary heating devices was higher in females compared to males (p<.01). Males felt more cold in the head and face compared to females (p<.01). Self-identified cold tolerance had negative relationships with the total number of winter outdoor clothes for both males (r=-0.260) and females (r=-0.222) (p<.01). The perceived old age for both males and females was 72.4 yr. Sex differences should be considered when developing guidelines for winter clothing behavior for the elderly and educating them on how to improve health and cold tolerance.

The intestinal immune system can discriminate between harmful and unharmful antigens and do not provoke productive immunity to unharmful antigen. Thus oral administration of antigen is one of classical methods for inducing antigen-specific immune tolerance in the periphery. Furthermore, oral tolerance has been investigated for the treatment of autoimmune disorders in human clinical trials. However, the detail mechanism of oral tolerance and contributing factors are not defined clearly at this time. Recent studies demonstrate unique types of immune cell that suppressing immune response, such as regulatory T cell and tolerogenic dendritic cell. This article reviews the factors involved in oral tolerance and discusses our current understanding base on the recent literatures and our works.
