For this study, we developed clothing in which textile materials that were excellent weather control function for the cold environment and we performed the human subject test with developed clothing to determine the thermal comfort. We used 2 clothing samples developed (A and B, hollow yarn+moisture absorption/quick drying yarn, 3 layers, high stretchable, heat reflection film and lamination treated) and a control sample (Ctrl.) for the human subject test and 8 adult males were used as a human subjects and environmental conditions of chamber were $0{\pm}1^{\circ}C$. $50{\pm}5%RH$, 0.3m/sec. The results were as follows: The average skin temperature and hand, thigh temperature of B were higher than B and Ctrl. (p<.05). The micro-climates of B were near to thermal comfort range which is $32{\pm}1^{\circ}C$ and $50{\pm}10%\;RH$. The chest temperature of B was significantly higher than others (p<.05). The relative humidity of B was lower than others and kept stable rather than others. The thermal sensation of B was near the "neutral" and was significantly different from Ctrl. (p<.01) and the weight loss of B was lower than Ctrl. (p<.05). The counting task and hand temperature was positively related and the counting task value of B and A is bigger than Ctrl. and that of A was bigger than Ctrl. (p<.05).

Large quantities of by-products—such as fish frame, head, skin and viscera—are generated during seafood processing, and these by-products are not utilized extensively. Therefore, sea rainbow trout Oncorhynchus mykiss (SRT) frame muscle (FM) jerky was prepared by grinding SRT-FM, followed by mixing with seasoning, forming and drying. The nutritional and microbiological characteristics of the SRT-FM jerky were then investigated. The proximate composition of the SRT-FM jerky was 19.1% moisture, 38.7% crude protein, 7.9% crude lipid and 4.4% ash. The viable bacterium count of the SRT-FM jerky was 3.9 log CFU/g, and Escherichia coli and Staphylococcus aureus were not detected. The total amino acid content of SRT-FM jerky was 37.3 g/100 g, and the major amino acids were aspartic acid, glutamic acid, leucine and lysine. Based on the recommended daily intake of fish jerky (100 g), the most abundant mineral was potassium. The fatty acid composition of the SRT-FM jerky was 26.2% saturated acid, 34.5% monoenoic acid and 39.3% polyenoic acid, and the major fatty acids were 16:0, 18:1n-9, 18:2n-6, 20:5n-3 and 22:6n-3. These results suggest that SRT-FM jerky has high nutritional value.

This study intends to present basic materials for the development and production of functional dumpling skins by making rice flour-added functional dumpling skins and analyzing the nature of its quality. The moisture content of dumpling skins increased with high addition of rice flour. The color value of dumpling skins changed little with high addition of rice flour. The hardness of dumpling skins showed significant difference in all storage periods with the addition of rice flour. For the sensory properties of dumpling skins with the addition of rice flour, where 25% and 50% rice-flour were added, dumpling skins showed a high score in overall quality for O-day and 7-days of storage. In particular, the 50% rice-flour dumpling skin mixture indicated the highest score. For the correlation between textural and sensory properties according to the addition of rice flour, 0 day-stored dumpling skins showed a positive correlation between smoothness and moistness in the mouth feel and the overall quality (p<0.01) in the sensory properties. Wheat odor (r=0.68) and chewiness (r=0.65) also correlated positively with overall quality (p<0.05). Hardness in textural properties correlated positively with moistness (r=0.69) and the mouth feel (r=0.65) of dumpling skins (p<0.05). Hardness in textural properties correlated positively with adhesiveness (r=0.99) and chewiness (r=0.93, p<0.01). Dumpling skins stored for 7 days showed a positive correlation between hardness, chewiness, and moistness in the mouth feel and overall quality (p<0.05) in the sensory properties. Hardness in textural properties correlated positively with gumminess (r=0.65, p<0.05).

We investigated the antioxidant, physicochemical, and sensory characteristics of dried type sodium reduced chicken bibimbap using dandelion complex extract powder of AF-343 (DCEP) as a home meal replacement. The DCEP is known to add moisture to the skin and to relieve the symptoms of atopic dermatitis. The sodium content of the standard sample was 1,190 mg per serving. The sodium was significantly reduced by 30%, resulting in 820 mg of sodium for the reduced-sodium group (p<0.05). The ash contents of the standard sample group with the DCEP showed significantly the highest value at 6.01% in all of the samples as affected by the minerals of the DCEP (p<0.05). Sensory characteristics of savory aroma, savory flavor, cooked vegetable flavor and hardness in all the samples did not show significant differences, implying that addition of DCEP and 30% sodium reduction did not have undesirable effects on those sensory attributes. Furthermore, chicken flavor, which was a bit oily in the standard samples tended to decrease slightly, leaving a desirable savory flavor increased in the reduced sodium groups. In acceptance tests, the samples did not show any significant differences, indicating that the DCEP added sodium-reduced samples may be potentially acceptable to consumers. Total flavonoid contents, ABTS and DPPH radical scavenging activity, indicators of biologically active ingredients such as antioxidant, anticancer, and antibacterial activities significantly increased with the amount of DCEP added (p<0.05).

In order to investigate the mechanism of the formation of clothing microclimate with different blouse designs and materials, physiological and subjective sensational changes were measured. Experimental clothing were four types of blouse made of $100\%$ cotton, $100\%$ regular polyes­ter, and $100\%$ hygroscopic polyester. Four types of box style blouse were with stand collar and long sleeve, with stand collar and sleeveless, with long sleeve and collarless, and sleeveless and collarless. Five healthy female were chosen as subjects. Experiments were carried out in the environ­mental chamber controlled at $28{\pm}1^{\circ}C$ , $70{\pm}5\%$ RH. and still-air condition for SO min. The skin temperature (9 spots), oral temperature, humidity inside chest, and subjective sensations were measured. Obtained results are: I) Material which is capable of absorbing sweat effectively and transfering moisture rapidly made a comfortable feeling, because cloth­ing humidity is increasing slowly at this material. 2) During exercise period, covered arms have more influenced on thermal comfort than a covered neck.

Three isocyanatopropyldimethoxysilylpolydimethylsiloxanes(IDMSi-PDMS) were synthesised from the reaction of isocyanatopropyltrimethoxysilane with monohydroxyl group termainated PDMS having different molecular weight($M_n$=5000, 10000, and 20000). Then PDMS modified polyurethane hybrid elastomer(PSMPH) were prepared from the reaction of IDMSi-PDMS with ${\alpha}$, ${\omega}$-hydroxyl group terminated polyurethane. PSMPH sealant was prepared by compounding PSMPH elastomer with additives such as plasticizer, adhesion promoter, crosslinking agent, vicosity increasing agent, inorganic filler, and catalyst at room temperature under nitrogen atmosphere. The methoxy group in the PSMPH sealant should be crosslinked with the hydroxyl group in the building stone or moisture by typical sol-gel reaction. The adhesive strength of the sealant having PDMS of $M_n$=5000 showed 40.28 kg of maxium load and 20.14 kg of break load. The shrinkage rate of the sealant having PDMS of $M_n$=20000 was 5.7% as the best result. Also, their skin over time, slump, oil content after 8 days under oil soaked paper and alkaline resistance characteristics show good results.

Capacitive-type humidity sensors with a high sensitivity and fast response/recovery times have attracted a great attention in non-contact respiration biological signal monitoring applications. However, complicated fabrication processes involving high-temperature heat treatment for the hygroscopic film is essential in the conventional ceramic-based humidity sensors. In this study, a non-toxic ceramic/metal halide (BaTiO₃(BT)/NaCl) humidity sensor was prepared at room temperature using a solvent-free aerosol deposition process (AD) without any additional process. Currently prepared BT/NaCl humidity sensor shows an excellent sensitivity (245 pF/RH%) and superior response/recovery times (3s/4s) due to the NaCl ionization effect resulting in an immense interfacial polarization. Furthermore, the non-contact respiration signal variation using the BT/NaCl sensor was determined to be over 700% by maintaining the distance of 20 cm between the individual and the sensor. Through the AD-fabricated sensor in this study, we expect to develop a non-contact biological signal monitoring system that can be applied to various fields such as respiratory disease detection and management, infant respiratory signal observation, and touchless skin moisture sensing button.

This study is to make the liquid crystalline structure using sucrose distearate (Sucro-DS) emulsifier to create the hydrophilic type oil-in-water (O/W) emulsion, the droplets of the emulsion having a structure of a multi-lamellar structure. We have studied the physicochemical properties of Sucro-DS using those techniques. And it has been studied in the emulsion performance. In order to form the liquid crystalline structure applying 3 wt% of Sucro-DS, 5 wt% of glycerin, 5 wt% of squalane, 5 wt% of capric/caprylic triglyceride, 3wt% of cetostearyl alcohol, 1wt% of glyceryl mono-stearate, 78 wt% of pure water in mixture having the lamellar structure of stable multi-layer system was found to formed. By applying them, they were described how to create an unstable active material encapsulated cream. Further, the moisturizing cream was studied using this technique. It reported the results to the skin improvement effect by the human clinical trials. The pH range to produce a stable liquid crystal phase using a Sucro-DS was maintained in 5.2~7.5. In order to increase the stability of the liquid crystal, it was when behenyl alcohol containing 3 wt%, the hardness at this time was 13 kg/mm,min. Viscosity of the same amount was 25,000mPas/min. After a test for the effects of the emulsions, the concentration of 6 wt% Sucro-DS is that was appropriate, the particle size of the liquid crystal was 4~6mm. It was observed through a microscope analysis, reliability of the liquid crystal changes for 3 months was found to get stable at each $4^{\circ}C$, $25^{\circ}C$ and $45^{\circ}C$. In clinical trial test, before applying a moisturizing effect it was $13.4{\pm}7%$. Moisturizing cream liquid crystal was not formed in $14.5{\pm}5%$. Therefore, applying than ever before could see the moisture about 8.2% was improved. On the other hand, it was the moisturizing effect of the liquid cream is $19.2{\pm}7%$. The results showed that 43.3% improvement than that previously used. Applications fields, Sucro-DS emulsifier used liquid cream, lotion, eye cream and a variety of formulations can be developed, as well as the cosmetics industry is expected to be wide fields in the application of the external preparation for skin emulsion technology in the pharmaceutical industry and pharmaceutical industry.

In this study, the skin moisturing effect and stability of cream containing L. cuneata G. Don extract (ethyl acetate fraction) were evaluated. The skin hydrating effect of the cream containing extract was 1020% higher than the placebo cream, and the TWEL of the cream containing extracts was decreased to $7.7g/m^2h$ compared to the control ($10.2g/m^2$) and placebo cream ($8.9g/m^2$). The pH, viscosity, and absorbance were measured under the 4, 25, 37, $45^{\circ}C$ and the sun light during the 12 weeks. The pH change between cream containing extract and placebo cream did not show the significant difference under the 4, 25, 37, $45^{\circ}C$ except for the sun light. Both creams showed high decrease (about 59%) of viscosity at $45^{\circ}C$. However, there was no significant change under other conditions. The absorbance of the cream containing the extract and the placebo cream was decreased similarly at all conditions. This decrease in absorbance was relatively small compared to the decrease of absorbance of the extract in ethanol solution under the sun light (Fig. 7). In addition, any change in color or smell of the cream was not observed during the 12 weeks. Also physical changes as creaming and cohesion were not shown. These results indicate that the cream containing L. cuneata extract has the skin moisturizing effect and is relatively stable. Therefore, it is suggested that the ethyl acetate fraction of L. cuneata extract could be applicable to cosmetics as a new cosmetic material with its antioxidative and antibacterial activities reported previously.
