This research analyzes characterization and classification of body types for the Chinese women with body measurement values. The measurement has gauged in 1999 in Beijing Institute of Clothing Technology in China. 100 women of the Chinese college women aged 17 and 24 in China were mwasured for this research. In the results of frequency analysis, the tall of Chinese women were 158.37㎝ and also has less than 150㎝ high, and has thick under bust circumference, and has a group of more than 18㎝ for width of nipple to nipple. In the results of factor analysis. Factor 1 represented the degree of abesity, while factor 2 indicated the stature and the arm length. The body types are classified into five types by cluster analysis. The stature and weight varied according to types, leading to a classification focusing on the body size determined by stature and weight factors.

We carry out 100-GHz band test observations with the newly-constructed KVN 21-m radio telescopes in order to evaluate their performance. The three telescopes have similar performance parameters. The pointing accuracies are about 4" rms for the entire sky. The main beam sizes are about 30" (FWHMs), which is nearly the diffraction limit of the telescopes at the observing frequency (97 GHz). The measured aperture and main-beam efficiencies are about 52% and 46%, respectively, for all three telescopes. The estimated moon efficiency is ~84% for the KVN Tamna telescope. The first sidelobes appear 50" (~1.6${\times}$FWHM) from the main beam centers and the levels are on average -14 dB.
Topical Hypopigmenting Agents for Pigmentary Disorders and Their Mechanisms of Action
( Hyo Jin Kim ),( Dong Seok Kim ),( Kyoung Chan Park ),( Hye Ryung Choi ) 대한피부과학회 2012 Annals of Dermatology Vol.24 No.1
Melanin is produced in melanocytes and stored in melanosomes. In spite of its beneficial sun- protective effect, abnormal accumulation of melanin results in esthetic problems. Hydroquinone, competing with tyrosine, is a major ingredient in topical pharmacological agents. However, frequent adverse reactions are amongst its major limitation. To solve this problem, several alternatives such as arbutin, kojic acid, aloesin, and 4-n-butyl resorcinol have been developed. Herein, we classify hypopigmenting agents according to their mechanism of action; a) regulation of enzyme, which is subdivided into three categories, i) regulation of transcription and maturation of tyrosinase, ii) inhibition of tyrosinase activity, and iii) post-transcriptional control of tyrosinase; b) inhibition of melanosome transfer, and c) additional mechanisms such as regulation of the melanocyte environment and antioxidant agents.

마가목은 한방에서 기침, 천식, 기관지 질환 등의 치료에 이용되고 있다. 본 연구에서는 마가목(sorbus commixta) 수피의 chloroform 분획물로부터 3종의 triterpenoid 화합물과 1종의 coumarin 화합물을 분리하였다. 분리된 화합물의 구조는 MS와 1D-, 2D-NMR분석에 의해 확인하였으며, 이들은 lupeol, β-sitosterol, ursolic acid와 scopoletin으로 구조동정되었다. 분리된 화합물 중 scopoletin은 마가목에서 처음으로 분리된 화합물이다. Scopoletin은 식물에 널리 분포하고 있는 물질로써 항염증 활성을 가진 기능성 화합물이다. 분리된 화합물들의 혈관 염증 억제에 대한 효과를 평가하기 위해 in vitro에서 LDL 산화 억제능을 평가한 결과, 분리된 화합물 중 scopoletin (IC50=10.2 μM)이 강한 억제 활성을 나타내었다. TNF-α로 활성화된 인체혈관내피세포(EA.hy926)를 이용한 실험에서 scopoletin은 세포부착인자인 ICAM-1, VCAM-1, E-selectin의 발현을 저해하였고, THP-1 단핵구와 EA.hy926 혈관내피세포 간의 부착력도 약화시켰다. 뿐만 아니라, scopoletin은 TNF-α로 유도된 NF-κB 전사인자의 핵내 이동 및 IκBα의 인산화도 저해하였다. 따라서 마가목 추출물로부터 분리된 scopoletin은 NF-κB 신호전달의 억제를 통해 세포부착인자의 발현을 감소시키고, 단핵구의 혈관내피세포로의 부착을 억제시켜 혈관내 항염증 활성을 나타내었다. 이러한 실험결과, scopoletin은 혈관염증 반응으로부터 유도되는 죽상동맥경화증 치료를 위한 후보소재로서 이용될 가능성이 있다고 사료된다. Sorbus commixta Hedl. has traditionally been used as a remedy for cough, asthma, and other bronchial disorders. In this study, three major triterpenoids—lupeol, β-sitosterol, and ursolic acid and a coumarin, scopoletin, were isolated from a CHCl3-soluble fragment of the bark of S. commixta. Their structures were identified by spectroscopic analyses, including mass spectrometry (MS), 1D-, and 2D- nuclear magnetic resonance spectroscopy (NMR), as well as by comparing the data with data reported in the literature. Scopoletin was isolated from this plant for the first time. It is a nutraceutical compound contained in many plants that has been reported to exert diverse biological activities, including anti-inflammatory effects. This study examined the inhibitory effect of scopoletin on TNF-α-induced vascular endothelial inflammation. Unlike the marginal impact of other compounds against low-density lipoprotein (LDL) oxidation and vascular endothelial inflammation, scopoletin showed remarkable activity on LDL oxidation (IC50 = 10.2 μM) and exerted vascular anti-inflammatory effects in EA.hy926 human endothelial cells activated by TNF-α. It suppressed the expression of adhesion molecules, such as ICAM-1, VCAM-1, and E-selectin, and blocked the adhesion between THP-1 monocytes and EA. hy926 endothelial cells. It also inhibited TNF-α-induced NF-κB translocation from the cytosol to the nucleus. Moreover, IκBα phosphorylation, which was increased by TNF-α treatment, was reduced after treatment with scopoletin. Thus, scopoletin inhibited TNF-α-induced vascular inflammation in endothelial cells by suppressing the NF-κB signaling pathway. These results demonstrate that owing to its anti-inflammatory activity in the vascular endothelium, scopoletin has the potential to inhibit atherosclerosis development.
Induction of Glyceollins by Fungal Infection in Varieties of Korean Soybean
( Mee Ryung Lee ),( Joo Yeon Kim ),( Ji Yeon Chun ),( Sun Min Park ),( Hyo Jung Kim ),( Jong Sang Kim ),( Jong Il Jeong ),( Jeong Hwan Kim ) 한국미생물 · 생명공학회 2010 Journal of microbiology and biotechnology Vol.20 No.8
Glyceollins, one of the inducible phytoalexins produced by plants, were induced in a number of varieties of Korean soybean through fungal infection. Of the tested soybean varieties, Tae-Kwang, though not the most productive, was found to be currently the most suitable for the induction of glyceollins. Amongst the fungal species, Rhizopus microsporus var. oligosporus was seen to be the most effective elicitor. Halved soybean seeds produced glyceollins upon fungal infection; however, chopped soybeans and homogenized soybeans did not produce significant quantities of glyceollins.

PURPOSE: This study examined the effects of the meridian muscle release technique on the pain and functional movement of patients with myofascial pain syndrome (MPS) of the shoulder joint. METHODS: The subjects of this study included 45 patients with MPS of the shoulder joint. The subjects were divided randomly into the following groups; the meridian muscle release technique group (n=15), the Graston technique group (n=15), and the control group (n=15). Both the meridian muscle release group and the Graston technique group received conventional therapy for 35 minutes initially and were then treated using the meridian muscle releases technique and Graston technique for 10 minutes, respectively. The control group received only conventional therapy for 35 minutes. All three groups underwent treatments three times a week for four weeks. Each subject was evaluated randomly using the VAS, PPT, SPADI and ROM both before and after treatment. RESULTS: The Graston technique group showed a significantly more substantial increase in functional movement (p<.05) than the meridian muscle release technique and control groups. The meridian muscle release technique group had significantly less pain (p<.05) compared to the Graston technique and control groups. CONCLUSION: These findings suggest that the meridian muscle release technique can be useful for decreasing pain and increasing the functional movement of patients with MPS of the shoulder joint.
