This research works’ objective is to observe the workers’ productivity by measuring the physiology and psychology based on the environment provided — the multivariate analysis presented to review the value of the significant data using JMP 11. Analysis of Variants and Bivariate Analysis then used to understand the cause-effect of the result gained. Result from of physiology that record the subject skin temperature and heart rate first analyze to break down the relationship between the environment to the body. Psychology test relating to the overall environment and their bodily feeling is questioned to the subject. The result then is analyzed using a scatter diagram and boxplot to observe its consistency. Four levels of air temperature and three levels of humidity were set in the room designed as a climate chamber for the respondent of who role as workers. The physiology result shows that the skin temperature and heart rate was the most significance that reacts to the air temperature, following up by the concentration level. Meanwhile, the physiology and psychology test consistently reveal that tropical natives highly react to hot temperature than colder temperature by agreeing to the label of uncomforted or dissatisfied and inform that the air temperature around 22°C. to 28°C. is suited for working productivity in the office in a hot-humid climate.

Recently attention has been focused on countermeasures against microorganisms such as viruses and microbe, in connection with pandemics of new forms of influenza or SARS, and the occurrence of bioterrorism. Also, in pharmaceutical or food production facilities, a high standard of internal environment of the facility is required, including countermeasures against microorganisms. These countermeasures from the facility point of view include partitioning of work zones (zoning), and cleaning the air using HEPA filters. However, when workers/researchers are working within a facility, dispersion of dust or adhering microbe brought in from clothes, etc., cause pollution of the air. In this report, the sterilization performance of weak acid hypochlorous solution used as the chemical substance was verified. In addition, the sterilization performance in an actual space varied not only with the chemical substance used, but also with the condition of the room, the air conditioning system, the method of spraying, etc. Therefore, from the above sterilization performance tests using chemical substances, the raw data required for a computational fluid mechanics (CFD) model were derived. A method that enables the effect of the chemical substance to be predicted under various conditions was investigated, and the results are reported.

Increasing the productivity of workers has great economic value and is essential for achieving a sustainable society and economic progress. Therefor the purpose of this study was to clarify the effects of different air-conditioning systems on human response and productivity. The following findings were obtained by this experiment.The skin temperature difference was larger in convection air conditioning than in radiant air conditioning.Male and Female differed in thermal environment satisfaction and air flow comfort for air conditioning and air velocity.Skin temperature difference, thermal environment satisfaction, and airflow comfort affected fatigue, and productivity increased when not tired.

The purpose of this research is to verify the necessity to control indoor humidity in Southeast Asia, while the setting temperature of indoor air is increased for energy-saving. Therefore, physiological and psychological responses to ambient humidity were studied using subject experiments in a climate chamber where indoor air condition can be controlled at discretion. For easily finding the characteristics of Southeast Asians, two subject groups, hot humid and temperate natives, participated in the test. As a result, this study revealed an existence of the variation in the physiological and the psychological reactions to a change in ambient humidity, regarding hot humid natives. In particular, a surrounding with high humidity tend to reduce heat flux on forehead and humidity acceptability. These circumstances could not be found in the temperate natives. The conclusion drawn from our experiments is that it is necessary to control not only indoor temperature but also humidity in the case of a building where there are occupants coming from hot humid locations. However, it remains a challenge for future researches to investigate the amount of sweating, physiological and psychological responses of the whole body and the influence of long-term acclimatization for artificial environment upon physical and mental well-being.
