This study is to evaluate moisturizing effect and durability of UV A/B blocking activity with multiple (W/O/W) emulsion system. Most of the sun protective products come to be hot issue having both high SPF and long-lasting activity as using special products when is going out, mountain climbing and sports. Also, many consumers prefer the products which have the excellent waterproofing activity of sun care cosmetics as well as the non-sticky feeling that carried out the study of the sensorial science and texture preference. Therefore, development of the specific formulation using this multiple (W/O/W) emulsion technology, it has O/W type hydro skin feel having soft and moist texture when it is treated on the skin. Finally, this formulation is instantly changed to W/O type feel after adsorbed into the skin. The purpose of this study is to get high SPF lasting effect having high water resistance tactivity with high functional multiple (W/O/W) emulsion cream. We used major ingredients, UV-B absorbers were selected with ethylhexyl methoxycinnamate, isoamyl-p-methoxycinnamate, ethylhexylsalicylate, and octocrylene, UV-A absorbers were selected with butylmethoxydibenzoylmethane, bis-ethylhexyloxyphenol methoxy phenyltriazine. SPF effect of O/W type cream was 34.1. SPF effect of W/O/W type cream was 40.6 (increased about 19%). Water resistance effect after 4 hours, SPF effect of O/W type cream was 3.6 (quickly drop down). SPF effect of W/O/W type cream having 81.0 % waterproofing effect was 32.7 (decreased about SPF 7.9). Moisturizing effect of O/W cream at first was superior comparing multiple emulsion. But after 3 hours quickly was drop-down. Moisturizing effect of multiple emulsion was high comparing O/W type and other sun block creams after 4 hours was constantly maintaining water-content.

The purpose of this study was to investigate the effect of perceiver's gender, clothing, and hairstyle on the visual evaluation of men's professionalism and preference. A quasi-experimental method by questionnaire was used. The experimental design was a $2\times8\times2$ (perceiver's gender $\times$ clothing $\times$ hairstyle) factorial design by 3 independent variables. The stimuli were 16 photographs of a man in his twenties. The upper clothing of the man included tailored collar jackets in beige and dark blue colors, and jumpers and sweaters in beige, dark blue, and red colors. The lower clothing of the men included jean pants. Two types of the hairstyles included short hair and medium length hair. The subjects were 208 men and 223 women in Seoul, Korea. Wearing a beige sweater with jean pants was evaluated high in intellectual image, a red jumper was perceived low in intellectual image, and a beige tailored collar jacket was evaluated low in potent image. Men's short hairstyle was evaluated to be more professional than the medium length hair. Male perceivers liked short hair more than medium length hair, but female perceivers evaluated both hairstyles similarly. In the case of women, the preferences of tailored collared jacket and soutien collared jumper were similar, but jumper was preferred to jacket in the case of men. Male perceivers showed more positive feedback towards jean pants with soutien collared jumper than jeans with tailored collared jacket, which indicated that men showed more conservative attitude towards the outfit than women. The man who was wearing a jumper with short hair was evaluated positively and the man who was wearing a jacket with medium length hair was evaluated negatively when the attires were coordinated with jean pants. In conclusion, medium length hairstyle with a beige jacket and short hairstyle with a red sweater were evaluated as professional image; and the results indicated that clothing and hairstyle interact with each other and influence the evaluation of professionalism.

The purpose of this study was to prepare low methoxyl pectins (LMPs) by pectinesterase (PE) using waste tangerine peels and to compare the chemical, physical and gelling properties of the prepared pectins with the commercial LMP. The LMPs were prepared by treating albedo with 0.25M $Na_2CO_3$ to activate the PE. PE was then inactivated by heating. The sample was centrifuged and the supernatant was collected. LMP was obtained as precipitate by adding alcohol to the collected supernatant. The amounts of extractible pectins in albedo were 12.71~12.98% on a dry weight basis. Methoxyl contents of LMPs prepared by treating albedo with PE at pH 7.5 for 10min, at pH 8.5 for 10min, 20min and 30min were 5.12%, 4.27%, 3.08%, 1.85% respectively, demonstrating that the methoxyl contents of the preparations decreased as the degree of treatment albedo with PE increased. The acetyl contents of the preparations ranged from 0.09% to 0.12%, the values of which do not interfere with gel formation. The anhydrouronic acid contents of the prepared pectins were in the range of 94.2%~94.8%. The values of viscosity and molecular weights of the prepared LMPs tent to decrease as the degree of PE action on albedo increased. The textural value of the prepared LMP gels determined by Consistometer, Ridgelimeter and Instron denonstrated that the excess treatment of albedo with PE significantly impaired the gelling properties of the preparations.

This experiment was conducted to select suitable cultivars and evaluate growth characteristics to get basic information for sprouting peanut. On sprouting peanut, it showed a rapid increase in trans-resveratrol content that has effects on anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular in mouse. For this experiment, characteristics of peanut sprouts were tested in 37 cultivars grown for 7 days at $26^{\circ}C$ temperature. There were a lots of variations in the growth characteristics among cultivars as followers : The range of 100 grain weight was 56 to 142 g, hypocotyl length was 4.3 cm to 5.8 cm, diameter of hypocotyl was 5.0 to 8.0 mm, epicotyl length was 0.8 cm to 4.6 cm, seedling ratio per seed number was 84% to 100%, weight per seedling was 4.9 g to 8.4 g, the rate of hypocotyl cleavage was 0% to 46%, the content of trans-resveratrol was $22.5\;{\mu}g/g$ to $88.2\;{\mu}g/g$ and sprout yield was 360% to 820%. The selection points considered were high sprout yield, high seedling rate, high resveratrol content, low brownish cotyledon, no hypocotyl cleavage, and fat hypocotyl etc. The best cultivar selected was 'Jokwang' that showed 7.8 mm diameter, clean cotyledon color, 100% seedling rate, 0% hypocotyl cleavage, $63.3\;{\mu}g/g$ resveratrol, and 820% sprouting yield. This cultivar was expected to be of use as a new food and nutraceutical material. Relationship between growth characteristics showed that root length had significant positive correlations with epicotyl length, resveratrol content and sprouting yield but negative correlations with hypocotyl diameter and cleavage. Hundred grain weight showed negative correlations with resveratrol content, seedling rate and sprouting yield but positively correlated with curved hypocotyl rate and hypocotyl cleavage positively. This result showed small grain seed will be more appropriate for sprouting peanut.

Acebrophylline is a compound produced by salifying ambroxol with theophylline-7 -acetic acid. After acebrophylline administration, the salt splits into these two components which feature a peculiar pharmacokinetic behavior, an adequate ambroxol and a low theophylline-7-acetic acid serum levels. The purpose of the present study was to evaluate the bioequivalence of two acebrophylline capsules, Surfolase (Hyundai Pharm. lnd. Co., Ltd.) and Burophil (Kuhnil Pharm. Co., Ltd.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The release of ambroxol from the two acebrophylline formulations in vitro was tested using KP VIII Apparatus II method with various dissolution media (pH 1.2, 4.0, 6.8 buffer solution and water). Twenty eight healthy male subjects, $23.25{\pm}1.43$ years in age and $64.82{\pm}6.77$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After two capsules containing 100 mg as acebrophylline were orally administered, blood was taken at predetermined time intervals and the concentrations of ambroxol in serum were determined using HPLC with electrochemical detector (ECD). The dissolution profiles of two formulations were similar at all dissolution media. In addition, the pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug Surfolase, were -1.64, -3.33 and -0.92% for $AUC_t$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 $(e.g., \;log\;0.93{\sim}log\;1.05\;and\;log\;0.88{\sim}log\;1.05$ for $AUC_t$, and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Burophil capsule was bioequivalent to Surfolase capsule.

To develop new therapeutic materials to prevent hair loss and enhance hair growth, we developed a medicinal herbal complex extract (MHCE) using 23 herbs traditionally used in oriental medicine. Medicinal Herbal complex extract was consist of Angelica gigas Nakai, Psoralea corylifolia Linne, Biota orientalis Endlicher, and Eclipta prostrata Linne, Rehmannia glutinosa Liboschitz var. purpurea Makino, Ligustrum lucidum Aiton, Polygonum multiflorum Thunberg, and Sesamum indicum Linne, Sophora angustifolia Sieboldet Zuccarini, Angelica dahurica Benthamet Hooker, and Leonurus sibiricus Linne, Salvia miltiorrhiza Bunge, Prunus persica Batsch, Commiphora molmol Engler, Chrysanthemum indicum Linne, Boswellia carterii Birdwood, Panax ginseng C. A. Meyer, Cnidium officinale Makino, Albizia julibrissin Durazzini, and Corydalis ternata Nakai that have traditionally been used for treating hair loss, preventing gray hair, anti-inflammation, and blood circulation in oriental medicine. In addition, we examined the hair growth effect of MHCE in vitro and in vivo. In vitro, we evaluated the effects of MHCE on cultured HFDPC, HaCaT cells, and murine embryonal fibroblasts (NIH3T3 cells). Also, we evaluated the ability of MHCE to prevent gray hair on murine melanoma cells (B16F1 cells). The hair growth-promoting effect of MHCE in vitro was also observed in vivo using C57BL/6 mice. Our results showed that MHCE significantly increased the proliferation of HFDPC (175 % proliferation at $50{\mu}g/mL$), HaCaT cells (133 % proliferation at $20{\mu}g/mL$), and NIH3T3 cells (120 % proliferation at $50{\mu}g/mL$). MHCE also showed consistent melanogenesis in B16F1 cells (154 % melanin synthesis at $50{\mu}g/mL$). Moreover, MHCE showed potential for hair growth stimulation in C57BL/6 mice experiments (98 % hair growth area on 4 weeks). These results indicate that MHCE may be a good candidate for promotion of hair growth.
