본 연구에서는 스탬프와 레진의 접촉-인장 방법을 이용하여 고 세장비를 가지는 폴리머 마이크로 헤어를 제작하는 공정을 제안하였다. 또한 광경화시 수축방향에 따라 마이크로 헤어에 표면주름이 다르게 생성되는 것을 실험적으로 관찰하였으며, 헤어의 직경이 $20{\mu}m$ 부근일 때, 일정한 패턴을 가진 표면주름이 제작되었다. 이 직경에서 스탬프와 레진의 접합력보다 수축력이 더 크게 되어 광경화 도중에 레진이 스탬프에서 분리되면서 단방향의 수축을 유도하게 되어 일정한 간격의 주름이 발생하는 것으로 사료된다. 본 연구의 기초결과를 이용하여, 향후 균일한 표면주름을 가지는 다양한 형태의 마이크로 폴리머 헤어를 제작할 수 있을 것으로 사료되며, 생체모사, 열전달 및 촉매 촉진과 같은 표면적과 관련된 기술 등 다양한 분야에 응용이 가능할 것으로 사료된다.

이 논문은 온라인 교육 콘텐츠에 나타난 젠더의 문화적 악순환 양상을 살펴보기 위하여 아동 전문 웹툰 플랫폼, 아이나무툰(EBS툰)의 인기 웹툰 상위 5위 작품에 재현된 젠더 양상을 검토하였다. 아동의 성별을 구분하는 외모 재현 양상, 성별에 따른 인물의 욕망과 문제 상황에서의 심리, 작품에서 수행하는 기능 등을 여성주의 시각에서 비판적으로 분석하였다. 여성과 남성의 외모 특질은 젠더 고정 관념을 답습하는 경우가 많았다. 대부분 여성은 긴 머리, 남성은 짧은 머리였으며 원피스를 입은 여성이 많았다. 그러나 심리적, 기능적 특질은 젠더의 상투성을 깬 측면이 있었다. 주인공의 성별 비중이 비슷하고, 양성 모두 해결사나 구원자로 기능하며 용감하고 지혜롭게 문제 상황을 극복해 나갔다. 그런데 주인공의 젠더 재현에서 젠더 고정 관념이 약하게 나타난 작품일수록 순위가 높았다. 이러한 사실은 아동 감상자들의 비판적 수용과 선택이 젠더의 문화적 악순환을 끊어내는 데 기여할 수 있음을 시사한다.

Objective : The Sinseon-yukza-hwan (SSY), a Korean medicinal formula which includes Radix Rehmanniae Preparata and other medicinal herbs, has long been used for treatment of alopecia and gray hair through oral administration. This study is designed to enhance the utilization of natural materials in hair and scalp-related cosmetics. Possibility of SSY as an antioxidant was examined from its 50% ethanol extract. Methods : The antioxidative capacities were evaluated by determining total phenolic and flavonoid contents, 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), reducing power and hydroxyl radical scavenging activity. Results : Total polyphenol and flavonoid contents of SSY were 25.53 mg TE, tannic acid equivalent/g and 18.90 mg RE, rutin equivalent/g, respectively, which correlated strongly its antioxidative activity. The DPPH and ABTS free radical scavenging activities of SSY at $0.1mg/m{\ell}{\sim}5mg/ml$ were ranged from 20% to 85% and 10% to 58%, respectively. Also the hydroxyl radical scavenger activity and reducing power increased in SSY-treated group, which were significantly lower in SSY-compared to BHA-treated group. But the highest reducing power was shown as 79% from SSY-treated group, which was higher value than 65% from BHA-treatment. These results showed that SSY extract effectively inhibited the generation of free radicals in the all assay system with dose-dependent manners. Conclusions : Thus, the present study provide preclinical data to support the expanded application of SSY, which could be potential candidates for natural antioxidants.

An aquatic oligochaete species, $Ripistes$ $parasita$ (Schmidt, 1847) collected from Ganghwado Island in Korea, is described and illustrated. Specimens inhabiting on aquatic vegetation at the edge of the streams were collected with a plankton hand net. Morphological features of present specimens such as the number of long hair chaetae per bundle and their length in VI-VIII, and shape and size of ventral chaetae are concordant with those of previous reports on this species. The genus $Ripistes$ contains one species, $R.$ $parasite$ which is distributed over, Europe, North America and eastern part of Asia including China and Japan. This is the first record of $R.$ $parasita$ in Korea.

Cave 79 of Kumtura grottoes, is the best preserved cave, which has an important meaning for research on Uighur costume. This paper is intended to analyze the costume characteristics of female donors in Cave 79 by comparing image materials between Dunhuang murals and other murals in Xinjiang province. In Cave 79, female donor wears red robe with tight sleeve, whose collar is crescent-shaped decorated. Two different opinions are upheld for this decoration. One regards this as the turn-down collar, while the other believes this as decoration on V-neckline. Red robe is quite common in female donors of Xinjiang and Dunhuang murals and a female in fresco is wearing a crown in a triangle red headwear style, regarded as red silk and drooping at head. Female donors wear an extra coat, kame hair clasp, red jacket, light-colored high-waist skirt with a long-tail waistband, and tangerine Pibo (silk ribbon) with scattered small flowers. All these costume styles are commonly-used by Han females. The kame headwear is also the common ornament for Han females and the female's hairstyle is in cone shape on head by a white kame. Current costumes are similar but not completely same.

Trace elements compose a very small portion of the body, however they have a variety of essential functions. Various diseases are caused by trace element deficiencies, and sometimes they can be fatal. Long-term TPN is a risk factor of trace element deficiency, and trace elements need to be checked regularly while receiving TPN. It is important to provide sufficient requirements of trace elements regarding the clinical features and the problems of trace element excess or deficiency. Moreover extensive studies to establish the efficiency of examining human hair and nails, recent method to determine the trace elements, are required.

Recently, a hyaluronic acid micro needle patch for therapeutic and cosmetic purposes has been used by attaching directly to the skin with a pattern having a micro needle shape of 1/3 thickness of hair. These products are attracting attention as an innovative product that maximizes the effect by activating the active ingredient in the skin in the deep skin without blocking the horny layer because the micro needle shape exists on the patch surface so that it can penetrate effectively to the skin. Currently, DAB (droplet air blowing) or MEMS technology is used to make pattern shapes for patches. Because of this technology, manufacturing time is long and manufacturing cost is high, so we tried to develop the mold technology to machine the microneedle shape directly to the metal. In this study, we first fabricated a needle pattern with a quadrangular pyramid shape and finally produced a conical needle pattern.

An 8-year old castrated domestic long-hair cat was presented with a two week history of abdominal distension. Physical examination revealed a non-painful, fluctuant, palpable mass in the right craniodorsal abdomen, and unilaterally muffled heart sounds on the right thorax. Routine clinico-pathological values were unremarkable apart from mild azotemia with a concurrent urine specific gravity of 1.031, which reflect a degree of renal dysfunction. Radiographic and ultrasound examinations of the thorax revealed the cardiac enlargement to be due to the congenital peritoneo-pericardial diaphragmatic hernia with liver occupying the right half of the pericardial sac. There was also a mild gypertrophy of the heart. Radiography and ultrasonography of the abdomen showed the mass to be composed of a large fluid filled cystic structures surrounding the right and left kidneys, and the kidneys themselves were of increased echogenecity. A diagnosis of perinephric pseudocysts was made. The patient responded well to the surgical procedures. Perinephric pseudocysts and peritoneo-pericardial diaphragmatic hernia in the cat are rare, and a case is described and the literature is reviewed in this report.

This study aims to analyze the characteristics and styles of wearing scarves in the contemporary fashion. Scarf-wearing styles found in the contemporary fashion are as follows: 1) Scarves are used as gorgeous hair accessories which are tied around the head like a headband, turban. 2) The second style is to wear scarves around the neck, which involves a variety of ideas. 3) Shawl-like scarves add elegance and femininity to any outfit when they are draped over the shoulders. 4) Scarves are also worn instead of or in addition to a belt with a dress, skirt, pants. 5) The style is to tie a scarf in knots at the back of the neck and the waist as it is shaped or in a diagonally half-folded shape. 6) You can tie a scarf to your hat or handbag or connect a long scarf to one part of your body.
