  • Purpose: Double skin facade is a representative advantageous passive technology of building skin in the aspect of energy saving and environment improvement, reduces heat loss with buffer space in winter season and enhances indoor air and comfort of residents by activating natural ventilation in mid-season. However, in summer season, temperature increase in the intermediate space due to solar energy from exterior transparent skin could be a potential problem; also, relatively weak buoyancy of air caused by low density difference between double-skin facade could increase cooling load as air of intermediate space in high temperature hangs. However, proof data is insufficient to objectify such phenomenon. Method: In this study, researchers surveyed air temperature of intermediate space and airflow and diagnosed its cause targeting on applied multistory facade in the building which gives thermal uncomfort to residents. Also, the researchers produced Solar-air heat transfer coefficient meter, measured thermal boundary condition of double-skin facade, and presented the result of measurement as an objectified verification material regarding overheating phenomenon in the intermediate space of double-skin facade in summer season. Result: Inefficient condition was verified that total heat increases and overheating due to insufficient natural ventilation in multistory facade. In addition, logic behind preceding research was objectified and verified regarding high temperature phenomenon in the intermediate space which could increase cooling load in summer season.

  • Today, men's appearance is an important part of the global fashion industry, including Korea, with such fashion concepts as the Metrosexual and Ubersexual. Domestic and overseas beauty and cosmetics related organizations are using this phenomenon for marketing and researching to improve the function of cosmetics. The purpose of this study was to investigate the effect of Prunus persica L. Batsch leaf extract on the skin condition after clinical application to male subjects with oily skin to determine the possibility of functional cosmetics utilizing this extract. The cleansing bars were prepared by the MP method and the cleansing packs were prepared using natural ingredients. After 8 weeks of application, moisture, oil, erythema, melanin, pH, elasticity and tactile sensation were measured using MPA5. The results showed that there was a statistically significant difference in T-zone moisture and T-zone oil after using the natural cleansing bar, but there was no significant difference between the two groups for other items. However, the statistically significant changes were found in the individual skin condition change items of the subjects in each group, and it was judged that the two kinds of formulations could be used at the same time to have a higher skin improvement effect. Thus, Prunus persica L. Batsch leaf extract demonstrates potential to be used as a functional cosmetics item.

  • The aim of this study was to evaluate the safety and effects of a soy lecithin-based supplement on the general health, skin condition, and blood lipid levels of dogs. Twenty-five, healthy, privately-owned dogs were enrolled in the study. Oral supplementation was administered for 8 weeks in the treatment group. Evaluation items included a thorough physical examination, owner responses to a questionnaire, blood analysis (CBC, CRP, serum chemistry, lipid profile). The results showed a significant improvement in amount of exercise, water intake, skin exfoliation in the treatment group (P < 0.05) but no significant changes in the other evaluation items, including no significant changes in blood component results following administration of the supplement. Most dogs well tolerated the treatment, and there were no serious adverse events. We suggest that soy lecithin has potential as a nutraceutical for the positive effect of general health condition such as activity and skin condition. Further studies are needed to establish the appropriate dose level and administration frequency of soy lecithin in dogs.
