  • Capsaicin cream has been used to attenuate the pain associated with diabetic neuropathy, rheum-atoid arthritis, osteoarthritis and postherpetic neuralgia. But its common side effect, local irritation, limits the use of it and there is still a need for a new analgesic devoid of this side effect. This study was conducted to compare the local irritant effect of DA-5018, a new capsaicin derivative, with that of capsaicin in various animal models and human beings. Capsaicin, applied topically to the mouse ear, produced dose-dependent increase of ear volume and the frequency of ear scratching behavior in mice. Neither ear volume nor scratching behavior was affected by DA-5018. In eye wiping test of rat, DA-5018 was 10 times less irritant than capsaicin. Capsaicin administered intradermally into the rat paw elicited paw lick/lift response with a potency which was three times that of DA-5018. Zostrix-HP (0.075% capsaicin cream), but not DA-50180.3% cream, increased ear volume of rat and induced thermal hyperalgesia in normal and carrageenan inflamed paws. Six day-treatment of Zostrix-HP failed to develop tolerance against this thermal hyperalgesia. In human beings, Zostrix-HP produced burning sensation and itching in more than 90% of volunteers involved and its maximum irritant effect was significantly higher than that of DA-5018 cream. These results suggest that local irritation and burning sensation produced by DA-5018 is much less than capsaicin.

  • The purpose of this study is to examine and to evaluate the wearing performance of pile materials to produce velvet fabrics which have excellent wearing comfort. Acetate velvet, Cuprammonium rayon velvet were combined as textiles for clothing and acetate and viscose rayon were as textiles for lining at the environmental condition of temperature $15^{\circ}C,\;18^{\circ}C,\;21^{\circ}C,\;24^{\circ}C$, relative humidity $50{\pm}5%$ and air velocity 0.25 m/sec. Wearing comfort among 4 materials combinations(Aa, Av, Ra, Rv) was examined and compared. The results are as follows. The investigation of mean skin temperature for environmental temperature and material combinations showed that the mean temperature had a significant difference at the p<0.01 level in accordance with environmental temperature and material combinations.(Aa>Av>Ra>Rv) Moreover, in clothing climate only clothing temperature tended to increase almost linearly but at $24^{\circ}C$ there was no significant difference among textiles for lining compared with the other environmental temperatures. In subjective sensations thermal sensation and comfort sensation showed a significant difference in environmental temperatures and materials.(Aa>Av>Ra>Rv) Though a subject felt warmer, more humid, and more uncomfortable at $24^{\circ}C$ for all of the material combinations comparing with the other temperatures, there was no significant difference in materials.

  • This research was designed to compare the subjective evaluation of texture image and preference according to fiber blending ratio of men's suit fabrics. 110 subjects evaluated the texture image and preference of various fabrics. For statistical analysis, factor analysis, MDS, pearson correlation and ANOVA were used. The results were as follows: Sensory image factors of suit fabrics were 'smoothness', 'bulkiness', 'stiffness', 'elasticity', 'moistness' and 'weight sensation'. Sensibility image factors were 'classic', 'practical', 'characteristic' and 'sophisticated'. 'Bulkiness' and 'elasticity' sensory images showed high correlations with sensibility images. Fabrics with high wool blending ratio showed as 'classic' and 'sophisticated', 'bulkiness' and 'elasticity' texture images and fabrics with low wool blending ratio showed texture images of 'characteristic', 'surface character', 'stiffness', 'moistness' and 'weight sensation'. Wool fiber blending ratio affected on the purchase preference and tactile preference. Using regression analysis, it was shown that sensibility images had more of an effect on preference than sensory images. The thickness and pattern type showed positive effects and fiber blending ratio showed negative effects on the preference.

  • To assist the further development of hight-visibility clothing this study compared the visibility and subjective wear sensation of commercial protective vests with retro-reflecting materials or LEDs. Nine subjects compared high-visibility vests to evaluate how easy they were to see when exposed to the headlight of a car at night, and the subjects assessed the wear sensation of the vests also. The intensity and visibility of five different colored LEDs assembled on the five substrates separately were also evaluated to select the suitable LED color for night protective clothing. The intensity of illumination was measured by an illuminometer, and the visibility was evaluated by 11 participants both in a dark room and in front of a car outdoors at night. Results showed, the most effective LEDs were high intensity LEDs which shift blinking red and white were most effective. However, excessively high intensity of illumination could decrease the working efficiency. In subjective wear evaluation, the most favorable vest had a front opening, were adjustable at the sides, and had an electric power switch on the front of the vest.

  • To put it simply, thing theory is a study of meaningful capacities of materiality. Although T. S. Eliot regarded pathetic fallacy as the bad example of objective correlatives in his modernism poetry theory, it is clear that many objects in literary works reflect diverse human desires. Among many, Victorian sensation novels are the most distinct genre where the various paraphernalia in them indicate the distorted and exaggerated greed of the industrial revolution era. Whereas the male protagonists are usually related with the norms objects of authority such as portrait and locket, the female characters' connection with cosmetics and white dress shows their oppressed and fragile position in the patriarchal and hierarchical society. In the (post)modern society, the ambiguity of things has grown rapidly due to the increasing discrepancy between objects and things. In special, the new journalism and the psychological realism novels often reveal the post-truth phenomenon because consumerized audience depend more upon the attraction and affect than the mere evidence and facts. For the individual, according to object relations theory, these alternative facts are rather internalized into their mind as the internal object when they are motivated by the non/contact with primary caregivers in their childhood. The dominant material imagery in (post)modern fiction becomes the site of resistance because of their reconstructed and extended meaning. The object relations theory and thing theory can be effectively used to uncover the complicated meanings of desired objects by using the human-object's meaningful relations and early mental images that are secretly alive still in the present.

  • This study tests the performance of the recommended winter dress OnMapsi for an office worker through the analysis of skin temperature changes according to the heating environment. We tested and compared the effects of with/without undergarments for 4 male subjects in an artificial-climate chamber with two air temperatures of $19^{\circ}C$ and $22^{\circ}C$, $50{\pm}10%$ R.H. During the 60 minute experiment that simulated office work, the subjective feelings (that included thermal, humidity and comfort sensation, and skin temperature) were measured at equal intervals. The results show that the forehead and chest skin temperatures were not affected by air temperature or clothing type, while the hand and foot skin temperatures were affected at $0.3-0.9^{\circ}C$ depending on clothing type and $1.9-2.2^{\circ}C$ depending on air temperature. The mean skin temperature was decreased by the experimental time pass more with regular formal wear than with OnMapsi. The second experiment located the ambient temperature in which subjects wearing OnMapsi show equal skin temperaturesto those without undergarments at $22^{\circ}C$. Therefore it is possible to decrease heating temperatures to $18-21^{\circ}C$ in the office for winter OnMapsi wear that produces a skin temperature and thermal sensation that is the same as those at $22^{\circ}C$.
