[Microclimate characters of urban forest in Shenyang].

This paper analyzed the diurnal changes of the temperature and humidity in Shenyang urban forest during its different growth stages. The results showed that air temperature was the lowest in the morning and the highest at noon. The highest peak point of air temperature lagged behind that of solar radiation about 2 hours, due to the influence of forest environment. The annual air temperature amplitude was in order of stop-growth period (dormancy stage) (DS) > prophase of growth season (PGS) > anaphase of growth season (AGS) > medium-term of growth season (MGS). Soil temperature of PGS, MGS and AGS at daytime was higher than that at night, while that of DS was in reverse. The daily soil temperature amplitude at different growth stages was in order of upper soil layer (20 cm) >medium soil layer (40 cm) >lower soil layer(80 cm),while the diurnal soil temperature amplitude in the same soil layer was in order of PGS > AGS > DS > MGS (20 cm) and PGS > DS > AGS > MGS (80 cm). The diurnal change of relative humidity was reverse to that of air- and soil temperature, which was higher at night than at daytime, and was in order of MGS > AGS > DS > PGS.

[Influence of microclimate factors on ocular discomfort in video display terminal workers].

The objective of the present research was to evaluate the effect of environmental parameters (temperature, air velocity, relative humidity, illumination level, cubature) on ocular symptoms (tiredness, tearing, redness, blinking, itching, burning, photophobia, foreign body sensation, and heaviness) in a group of 54 male Video Display Terminal (VDT) workers. The subjects were employed in a public office placed in Messina and naturally ventilated; the investigation was performed in Spring time. Information about the ocular symptoms, occurring during the workshift, were gathered through a questionnaire; environmental measurements were performed by a data collector LSI. The results showed that 43 subjects out of 54 (79%) reported a lack of eye comfort; in addition the illumination level, temperature and air velocity were not consistent with those suggested by the Italian Regulatory Authority. A significant correlation between illumination level, temperature, air velocity and eye discomfort (tearing, heaviness, blinking, photophobia itching, respectively) was found. The Authors conclude that the inadequate environmental condition, possibility in interaction with the indoor chemical contaminants and the workload at VDT, may be responsible for the irritative eye symptoms complained by VDT-workers at workplace.

[Effectiveness of local cooling during work with isolating equipment under the conditions of heated microclimate].

It is demonstrated that the use of autonomous low-temperature panels for human cooling under ambient temperature of 40-80 degrees makes it possible to neutralize thermal load and to maintain capacity for work at a high level for rather a long time. Under higher temperatures effectiveness of cooling is not so significant since at 80 degrees it greatly decreases.
