Thermal properties of interior decorative material and contacted sensory cold-warmth I: relation between skin temperature and contacted sensory cold-warmth

The purpose of the study was to investigate the relation between the skin temperature of the palm and sensory cold-warmth after contact with some materials. Ten men and ten women were selected and introduced to 21 kinds of material for a contact test of 30 min without seeing the specimens in a climate-controlled room at 25±1C and 65% relative heemidity. The palm-contacted test materials and skin temperature of the palm, central fingertip, and back of the palm were measured during the experiment. A sensory evaluation test was applied to evaluate the contacted sensory cold-warmth. Results showed that the maximum temperature decrease of the fingertip (T _d) was positively related to the natural logarithm of the material's specific gravity (ln _u) and to the natural logarithm of the material's thermal conductivity (ln). There were also negative linear relations between the contacted sensory cold-warmth (S) with ln _u and ln; and there was a negative linear relation betweenS withT _d and betweenS with the value ofT _d by . The thermal osmotic coefficient (b) of wood and wood-based materials ranged from 3.63 to 3.97, and the materials were qualified as good thermal insulation materials. Furthermore, there was a negative linear relation betweenS andb. Accordingly, it is possible to evaluate the contacted sensory cold-warmth relying on the basic thermal properties of material.Part of this report was presented at the 49th Annual Meeting of the Japan Wood Research Society, Tokyo, April 2–4, 1999

Assessment of temperature and relative humidity conditioning performances of interior decoration materials in the Taipei area (II)

The purpose of this study was to explore the conditioning effects of wood panels (used as interior decorating materials). We examined hourly the temperature and relative humidity (RH) in a living environment based on the average values during winters from 1974 to 1990 in the Taipei area. Thirty-six interior finish materials attached to one inside surface of a 35cm³ simulation aluminum container were used in this study. An A/V value (surface area of interior decoration materials attached to container/inside volume of container) of 2.86m^–1 or various other A/V values and panel thicknesses had no significant effect on the room temperature changing ratio. The hygroscopic conditioning performances of these decorative materials were classified into four types in accordance withb values: type I (b>0.0200) included four solid woods (unfinished), two wood-based materials, three composite materials, and one inorganic material. Type II (0.0170<b<0.0199) included one solid wood, eight wood-based materials, and two inorganic materials. Type III (0.0070<b<0.0169) included 11 wood-based materials and four inorganic materials. The RH changing ratio decreased curvilinearly with increasing interior decorating panel thickness and A/V values in a sealed container, whereasb values increased with increasing interior decorating panel thickness and A/V values in a sealed container.Part of this report was presented at ICEUPT'99, Chi-Tou, Taiwan, ROC, May 21–23, 1999

The effect of Appalachian mountaintop mining on interior forest

Southern Appalachian forests are predominantly interior because they are spatially extensive with little disturbance imposed by other uses of the land. Appalachian mountaintop mining increased substantially during the 1990s, posing a threat to the interior character of the forest. We used spatial convolution to identify interior forest at multiple scales on circa 1992 and 2001 land-cover maps of the Southern Appalachians. Our analyses show that interior forest loss was 1.75–5.0 times greater than the direct forest loss attributable to mountaintop mining. Mountaintop mining in the southern Appalachians has reduced forest interior area more extensively than the reduction that would be expected based on changes in overall forest area alone. The loss of Southern Appalachian interior forest is of global significance because of the worldwide rarity of large expanses of temperate deciduous forest.
