  • Construction is considered one of the most hazardous industries because of fatalities on site due to workers' unsafe behaviour. Occupational Health and Safety Practitioners are providing safety training through modern technologies like immersive and non-immersive Virtual Reality (VR). Workers are repeatedly exposed to construction hazards and thus become accustomed to underlying hazards. Providing simulated accidents in VR safety training aims to minimize worker risk habituation but repeated exposure to accidents can affect risk habituation toward the underlying construction risk. To this end, this study proposes a simulated accident VR safety training environment that exposes workers to repeated construction hazards and simulates a fall accident when workers don't follow the safety procedure. Longitudinal experiments were conducted, and participants' risk perception was measured using questionnaires. The results revealed that simulated accident safety training has potential effects on construction workers. The outcomes of this study lay the foundation for further studies to employ a VR safety training environment that enables workers to experience simulated accidents. This contributes to the development of an improved VR safety training design, taking into account the appropriate interval at which it should be provided. Such an approach can help workers become more sensitized to construction risks.

  • Neuromodulation was introduced for patients with poor outcomes from the existing traditional treatment approaches. It is well-established as an alternative, novel treatment option for voiding dysfunction. The current system of neuromodulation uses an open-loop system that only delivers continuous stimulation without considering the patient's state changes. Though the conventional open-loop system has shown positive clinical results, it can cause problems such as decreased efficacy over time due to neural habituation, higher risk of tissue damage, and lower battery life. Therefore, there is a need for a closed-loop system to overcome the disadvantages of existing systems. The closed-loop neuromodulation includes a system to monitor and stimulate micturition reflex pathways from the lower urinary tract, as well as the central nervous system. In this paper, we reviewed the current technological status to measure biomarker for closed-loop neuromodulation systems for voiding dysfunction.

  • The purpose of this study was to measure safety-awareness among elementary students, identify their safety-practices and actual status of accidents. The study was also done to acquire basic information on safety education to help students be more aware of safety, and more active in accident-prevention activities. A random sample was taken of 763 5th and 6th grade students in 4 different elementary schools in Seoul. Of the 735 questionnaires collected, 684 were complete and were used in the analysis. SPSS was used to analyze the questionnaires. The results are summarized as follows. First, the overall safety-awareness score was relatively high at 139.06 of a maximum of 164. and respondents were most conscious of the section on Home Safety. Second, the safety-practices of the respondents was at the middle level with a mean score of 56.01 of a maximum of 80. The factors affecting the safety-practice of the respondents were education of their parents, recognized learning proficiency, awareness of need for safety education, and level of safety-education conducted by parents. Third, $53.4\%$ of the respondents had experienced one or more accidents during the past year. Most of the accidents occurred during play and recreation and home accidents were the most frequently reported accidents. The risk factors related to the occurrence of accidents were gender, relationship with friends, recognized learning proficiency, and awareness of traffic safety. Forth, higher safety-awareness was found to be directly related to higher safety-practices. Respondents with lower safety-awareness reported higher rate of accidents. In view of the results so far achieved, habituation and formation of safety-oriented actions among students are highly required to prevent accidents. In order to do that, development of safety-awareness and in-life enforcement of safety-practice need to come first.

An Unthinking Sage? Plotinus' Model of Non-Deliberative Action (생각하지 않는 현자(賢者)? 플로티누스의 비-숙고적 행동 모델)

  • The aim of this paper is to examine the so-called theory of automatic action attributed to Plotinus, according to which the sage can act automatically without deliberation or reasoning. Concerns were raised that such a theory runs the risk of turning the agent into an automaton by reducing action to mechanical reflexes to external stimuli. I attempt to show that Plotinus does not hold a theory of automatic action by arguing that the Plotinian sage's non-deliberative action is not automatic at all. For this purpose, I first draw attention to the non-deliberative action of the World-Reason (i.e. the reason of the World-Soul), which is supposed to present an ideal model of action. Indeed, Plotinus mentions that the World-Reason rules the world "as if automatically". This is, however, meant to indicate the spontaneous and natural manner in which the World-Reason rules. In this respect, the way the World-Reason works is compared to the way nature (i.e. the productive power of the World-Soul) works. But Plotinus points out that the World-Reason knows what to do, whereas nature works without knowing. In this connection, Plotinus makes it clear that the World-Reason does not calculate or deliberate about what to do because it already knows it. To clarify this point, I turn to Plotinus' analogy of practical wisdom (phronêsis) and skill, according to which the World-Reason is compared to an accomplished craftsman or artist, who confidently works without any doubt, hesitation or difficulty, thereby expressing her intelligence, unmediated by deliberation. From this perspective, non-deliberative action according to practical wisdom turns out to be superior to deliberative action. Plotinus admits that there are difficult circumstances in which even the skilled craftsman, unlike the World-Reason who always controls the whole situation, needs to deliberate or calculate, but he is nevertheless confident that the craftsman easily finds the solution. This suggests that the sage, who possesses practical wisdom, can act normally like a great master or virtuoso without deliberation, but in an emergency situation he also employs deliberation, but resourcefully and creatively responds to challenge. The attempt is made to elucidate the Plotinian model of sage's action with the help of Csikzentmihalyi's concept of 'flow' and Annas' application of it to the analogy of virtue and skill. Finally, it is shown that the sage's virtuous action, in spite of being a habituated action, is not a passive, routinized, automatic action, but an active, flexible, intelligent action.
