This study was performed to find out factors affecting degree of satisfaction with workers' working environment. The study subjects were 165 workers who were working at painting process of twelve furniture manufacturing factories in Incheon area. We used self-administered questionnaire containing general characteristics, working conditions, the degree of satisfaction with working environment, and the degree of satisfaction with working condition. In addition, we measured the exposure levels of occupational hazardous agents. The results were as follows; 1. Correlations between the degree of satisfaction with workers' working environment and the measured of occupational hazardous agents did not affect the degree of satisfaction with workers' working environment. 2. Factors affecting the degree of satisfaction with workers' working environment were not the exposure levels of occupational hazardous agents, but the degree of satisfaction with working condition, size of industry, health status, and types of ventilation system. As the degree of satisfaction with working condition was increased, the degree of satisfaction with working environment was increased. Also, for the workers who had good health status, the degree of satisfaction with work environment was appeared to be high. To increase the degree of satisfaction, with workers' working environment, firstly, effective work management and production control are required. Also, the worker's effort to negotiate continuously with top manager on improving working conditions is required. Secondly, developing heath promotion program to be appropriate for the characteristics of worksite is required. Moreover, leading worker's participation in health promotion program is very important to increase the degree of satisfaction with workers' working environment.

The effect of climate change has influenced humanity and ecosystem with tremendous changes in temperature. For the past 150 years, the national annual average temperature is 0.6 degree increased and the heating degree day reduced from April to November. However, December to January, the climate change was generated and the heating degree day increased. The blackout occured in 2011 and 2012 by increasing electricity consumption of heating and cooling equipment to the effects of climate change. That is because heating load accounted for 20% of building electric use. In this study, strengthening measures to reduce heating energy consumption is presented due to climate change in winter since 1980 to prevent blackout and reliable power supply for the building energy-saving design standards by Meteorological data provided by the National Weather Service were calculated using the heating degree days in order to present eighteen cities from 1980 to 2012. Insulation standards are presented to prevent black-out by the heating degree days. the heating energy demand was reduced almost 6% including 10% in Central, 5% in South and Jeju area based on strengthening of the insulation. It is applied to the entire country an annual economic effect of 250 billion won, and black-out can be prevented.

This study attempted to investigate cognitive load, vividness, and cybersickness in nursing students, in the last year of nursing college, who used a 360-degree video content for studying intravenous fluid infusion, one of the core fundamental nursing skills. The aim was to determine the correlation between the variables, and to decide whether the 360-degree video content can be used as an effective supplementary educational material in the regular curricula. This study, a descriptive research, was conducted from October 31, 2019 to November 14, 2019. The participants in this study were 64 students in the 4th year of nursing college at a university located in B City, South Korea. They were instructed to watch a 360-degree video content for intravenous infusion using a Samsung Head Mounted Display (HMD) while ensuring the safety of the students. The results showed that the scores, out of 7 points, for material design, self-evaluation, and physical effort for cognitive load in nursing students were 5.93±0.71, 5.92±0.71, and 5.64±0.74 points, respectively. In addition, the scores, out of 7 points, for mental effort and task difficulty were 2.55±1.08 and 1.94±0.75 points, respectively, and the scores for vividness and cybersickness in the participants were 5.82±0.84, and 2.57±0.98 points, respectively. Physical effort, self-evaluation, and material design for cognitive load in the participants were positively correlated with vividness (r=.379, r=.458, r=.507). In addition, mental effort for cognitive load was positively correlated with cybersickness (r=.684), whereas self-evaluation and material design were negatively correlated with cybersickness (r=-.388, r=-.343). Based on the results of this study, we believe that the 360-degree video content for intravenous fluid infusion can be used as an educational medium in regular and non-regular curricula. In addition, future studies are needed to specifically develop and verify teaching and learning methods on how to apply 360-degree video contents..
