In this paper, we will examine single face tracking algorithms with scaling function in a mobile device. Face detection and tracking either in PC or mobile device with scaling function is an unsolved problem. Standard single face tracking method with particle filter has a problem in tracking the objects where the object can move closer or farther from the camera. Therefore, we create an algorithm which can work in a mobile device and perform a scaling function. The key idea of our proposed method is to extract the average of skin color in face detection, then we compare the skin color distribution between the detected face and the tracking face. This method works well if the face position is located in front of the camera. However, this method will not work if the camera moves closer from the initial point of detection. Apart from our weakness of algorithm, we can improve the accuracy of tracking.

In order to clarify the cadmium(Cd) contents of normal deer, tissue samples including kidney, liver, muscle, spleen, heart, lung, rumen, abomasum, intestine, skin and bone were collected from 18 deer which were slaughtered in Korea. All samples were burned to ashes and analyzed for Cd contents by atomic absorption spectrophotometric method. The mean Cd contents in \mu\textrm{g}$/g wet matter for 18 deer were liver 0.013, kidney 0.286, muscle 0.010, spleen 0.001, heart 0.007, lung 0.005, men 0.019, abomasum 0.016, intestine 0.018, skin 0.016 and bone 0.312, respectively. Two samples in kidney, one sample in muscle out of 18 deer showed higher Cd contents than normal limit value of 0.50\mu\textrm{g}$/g for liver and kidney, 0.10\mu\textrm{g}$/g for muscle. In addition, three deer also showed higher Cd contents in one body tissue than normal limit value which reported foreign countries.

Objectives : Agrimoniae Herba is a herbal medicine widely distributed in Asia and contains flavonoids including catechin, quercitrin, rutin, hyperoside, and quercetin. This study aimed to investigate the anti-oxidant activity and skin barrier function of different solvent fractions (Hexane; methylene chloride, MC; ethyl acetate, EA; n-butanol, Bu; Water) obtained from Agrimoniae Herba. Methods : Anti-oxidant activity of different solvent fractions obtained from Agrimoniae Herba was investigated through total polyphenol contents, total flavonoid contents, 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity measurements. Then, filament aggregating protein (Filaggrin), Type I collagen, ceramide synthase (CERS) 3, and CERS4 were analyzed to evaluate the skin barrier strengthening effect of different solvent fractions obtained from Agrimoniae Herba on UVB-stimulated HaCaT cells. Results : As a result of measuring total polyphenol contents, total flavonoid contents, DPPH free radical scavenging activity, and ABTS radical scavenging activity, antioxidant activity was found to be excellent in the order of EA > Bu > MC > Hexane > Water. As a result of measuring mRNA gene expression of Type I collagen, Filaggrin, CERS3, and CERS4 after UVB-stimulated was applied to HaCaT cells treated with different solvent fractions obtained from Agrimoniae Herba, it was found to increase significantly in the Bu-treated group. Conclusion : Our findings show that the Bu sample obtained from Agrimoniae Herba has excellent anti-oxidant ability, which increases Type I collagen, Filaggrin, and ceramide synthetase in UVB-stimulated HaCaT cells to control the skin barrier improvement effect.

This study was performed in order to identify nutritional factors affecting on skin sebum content with 131 female university undergraduates in 2003. We measured the sebum contents of 4 facial spots to classify their skin types. Daily energy and nutrient intakes of the subjects were not deficient except in calcium and iron, which were 466.2 mg (66.6% RDA) and 8.5 mg (53.4% RDA) relatively. We observed no significant difference of energy and nutrient intakes among the 3 skin types. But significantly higher consumption of grains and slightly higher frequencies of several food groups (excepting starches) were shown in oily skin types, so they might have higher nutrient intakes. Serum indices and food preferences mostly revealed no difference among the 3 skin types. But in the oily skin type, serum phosphorus levels were significantly lower than others, suggesting phosphorus-rich food consumption like soft drinks and pains could lead to a dry skin type rather than an oily one. Also in the oily skin type, sweet taste preference was slightly tower than others; more-over, sweet intake was lower samely significantly. There was mostly no significant relationship between facial sebum contents and nutrient intakes, dietary behavior, food frequency and food preference except in some factors. Animal protein intake showed a significant negative relationship toward facial sebum content. On the other hand, in normal skin type, Fishes consumed was slightly higher than others, so that higher animal protein consumption presumably leads to normal skin type. Frequency of fried food and bacon and preference of fried foods showed slightly negative relationships toward facial sebum content. Regular meal times showed significantly increased facial sebum content.

The antioxidant capacities, total phenolic contents (TPC), and total quercetin contents (TQC) of a red (Chenjujuck), a yellow (Sunpower), and a white (Grasier) onion cultivar were determined in this study. Onion was separated into edible portion and dry skin. In the case of edible portion, the yellow onion had the highest antioxidant activity, followed by the red onion. The white onion showed neither antioxidant activity nor quercetin compounds. On the other hand, the dry skin of the red onion showed higher antioxidant activity than yellow onion skin. The white onion skin had slight antioxidant activity, low TPC, and no quercetin compounds. In addition, the flavonoid compounds of the edible portion and dry skins of these colored onions were analyzed by UFLC(ultra-fast liquid chromatography). The major compounds were quercetin 3,4-diglucoside and quercetin 4-glucoside in yellow and red onion edible portion, whereas the major compounds in yellow and red onion skins were quercetin 4-glucoside, quercetin, and quercetin 3,4-diglucoside.

천연보습인자(NMF, natural moisturizing factor)는 정상 피부 내의 각질층에 존재하는 수용성, 친수성 성분을 총칭하는 말로 외부로부터 수분을 흡수하고 각질층의 수분보유능을 증가시키며 피부가 건조해지는 것을 방지하여 피부의 유연성과 가수성을 유지하는 기능을 한다. NMF는 주로 아미노산과 아미노산의 대사산물로 구성되며 이들은 필라그린(filaggrin)이 분해되면서 생성된다. 본 연구에서는 피부 각질층의 22종의 개별 아미노산의 함량분석을 통하여 피부보습능과 개개의 아미노산과의 상관관계를 연구하였다. 15명의 건강한 지원자들의 전박과 이마로부터 tape stripping한 각질 시료 중 22종의 아미노산 함량을 UPLC-PDA를 이용하여 동시 분석하였다. 그 결과 각질 표면보다는 안쪽에서의 아미노산들의 함량이 높음을 확인하였다. 또한 신체 부위별 비교에서 전박이 이마에 비해 아미노산 함량이 1.5배 정도 높음을 확인하였다. 전박부위의 아미노산 총 함량과 보습능(TEWL)과의 상관 관계분석을 통해서는 보습능이 클수록 총아미노산 함량이 높은 것으로 확인되었으며 특히 Ser, Glu, Gly, Ala 및 Thr은 각질 내 존재하는 주요 아미노산 성분으로 보습에 긍정적인 영향을 주는 성분으로 확인되었다. 이상의 결과로써 NMF의 주성분인 아미노산의 함량은 각질 생리기능과 밀접한 관련을 가지고 있음을 확인할 수 있었으며 본 연구를 통해 얻은 각질층의 아미노산의 통합적인 분석법은 보습, 노화, 미백, 피부 염증질환 등 다양한 피부 상태와 아미노산류들의 변화와의 관계를 깊이 이해하고 피부 기능과 관련된 새로운 분자적 타겟을 발굴하고 증명하는데 기초적인 방법으로써 사용될 수 있을 것으로 사료된다.

The purpose of this study was to develop a cooking method for skate pipyun made from skate skin and water. As the gel formation conditions, several skin contents (30~60%) and cooking times (10, 14, and 18 min) were determined. Test for quality characteristics of pipyuns was carried out by measuring texture, water content and pH, sensory evaluation, and heat stability of pipyun gel: five samples (S2: 40%, 10 min, S3: 50%, 10 min, S6: 40%, 14 min, S9: 30%, 18 min, S10: 40%, 18 min) with appropriate gel texture were selected based on their hardness, adhesiveness, and springiness. There was no difference in color among the five pipyuns. Hardness, chewiness, and gumminess of pipyuns significantly increased depending on skate skin content and cooking time. Water contents were significantly higher in S2 (83.40%) and S6 (82.97%). The pH levels of pipyuns appeared to be weakly alkali in the range of 8.17~8.71. In the sensory evaluation, S2 was the most preferred overall with significantly higher evaluation of transparence, gloss, and smoothness. The stability of gels S2 and S9 decreased during storage at $10^{\circ}C$ for 8 hours, and at $20^{\circ}C$ for 60 min. Therefore, heating a mixture of 40% skate skin with 60% water for 10 min is recommended as optimum conditions for producing skate pipyun.

To increase the collagen recovery rate, bromelain (PB) and a microbial enzyme (PM) were used to treat to pork skin with single agent or combinations. The quality of collagen from the pork skin was evaluated by enzymatic treatments. The highest results for the solid contents and pork skin recovery rate obtained with the microbial-enzyme-bromelain mixtue (PMB) were 13.60% and 18.05% respectively. The result also showed that the color was affected by different types of enzyme treatments. Although PM treatment showed the highest result in the protein content of 251.30 mg/100 g, PMB treatment was the highest in the test of collagen content of 37.73 g/100 g among the treatments. However bands of the pork skin were detected widely at 130 kDa and 170 kDa ranges in SDS-PAGE. The band of PB treatment showed at the range of below 17 kDa, changed into a smaller molecular weight. The collagen content test of the pork skin by the treatments, collagen contents with combination treatment of pork skin with PMB (0.5%) resulted the highest in 43.76 g/100 g. Also the fat content at the above treatment was reduced to 11.12% compared to the other treatments. With these results of this experiment, we conclude that the enzymatic treatments were effective for the processing property of pork skin like enhancing the yield of collagen.
