Objectives: The purpose of this study was to investigate distribution of pattern identification by age in stroke patients. Methods: From 1 April, 2007 to 29 September, 2008, 903 patients within a month after onset of stroke were included. Stroke patients were interviewed by oriental medicine doctors who used standard operation procedures for this study. A questionnaire was completed by a question-and-answer form between patients and doctors after explanation of details to patients and patients' agreement given. Results: Distributions of pattern identification in stroke patients differed by age groups. Dampness-Phlegm pattern was more common in the younger group aged under 80 years, while Yin-Deficiency pattern was more common in the older group aged over 80 years. Conclusions: In this study, we found a character of distribution of pattern identification by age in stroke patients within one month after stroke onset. We have concluded that these differences should be considered in the management and treatment of stroke patients.

웹 서비스는 오늘날의 인터넷 환경에서 분산되어있고, 이질적인 시스템들 간에 상호운용을 제공하는 새로운 소프트웨어 시스템의 형태이다. 이러한 환경에 있어서 보안은 가장 중요한 이슈 중 하나이다. 공격자는 아무런 인증 없이 사용자의 비밀정보를 노출시킬 수도 있다. 더구나 유비쿼터스 환경에서 사용자들은 웹 서비스를 이용하기 위해 반드시 그들 대신 서비스를 처리할 에이전트들에게 그들의 권한 모두를 혹은 그 중 일부분을 일시적으로 위임해야만 한다. 이것은 사용자의 비밀정보가 에이전트들을 통해 외부에 노출되는 결과를 초례한다. 본 논문에서는 유비쿼터스 환경에서의 안전한 웹 서비스를 위한 위임모델을 제시한다. 우리는 에이전트를 통한 비밀정보의 노출을 막고 서비스의 기밀성과 단언정보의 무결성을 제공하기 위해 XML암호화와 XML전자서명 방식을 이용한다. 그리고 XACML 기반의 웹 서비스 관리 서버를 통해 웹 서비스 제공자들과의 서비스정책의 상호운용을 수행한다. 우리는 역시 멀티 에이전트들 간의 위임을 통해 웹 서비스 제공자들에게 전달될 위임 단언을 정의하기 위해 SAML을 확장 시킨다.

Background. Breast cancer is the most common form of cancer among Korean women. Only 14 % of urban women and 10% of rural women in Korea, however, participated in breast cancer screening behavior in 1998 (Korean Ministry of Health & Welfare, 1999). Purpose. The aim of this study was to evaluate the effect of community-based breast self-examination (BSE) education programs in Korea. Methods. First, breast cancer risk appraisals were done with 1,977 rural women. Of the 1,977 women, nearly 30% (n=494) had a higher or equal to borderline risk of developing breast cancer. This quasi-experimental study was conducted to target these women with a high or equal to borderline risk of breast cancer. The risk appraisal feedback and breast self-examination education were used as an intervention for breast cancer prevention and early detection. Results. After a 3-month follow-up, 30.5% of the women in the intervention group performed regular BSE compared to 10.2 % of women in the control group. The mean knowledge score related to breast cancer and BSE was significantly higher for the women in the intervention group than that in the control group.

In order to examine the anti-ohyul (anti-inflammatory) activity of rhubarb, we investigated the effects of stilbene derivatives obtained from rhizomes of Rheum undulatum on the carrageenan-induced hind paw edema in rats. Administration of stilbene aglycon (rhapontigenin) at doses of 50 and 100 mg/kg exhibited the anti- edema effect in dose dependent manner and stilbene glycosides $(rhaponticin,\;piceatannol-3'-O-{\beta}-D-glucopyranoside)$ at a dose of 100 mg/kg also showed inhibitory effect on the carrageenan-induced edema. These inhibitory effects may ascribed, at least in part, to the anti-ohyul activity of rhubarb.

This study was to obtain essential information that can be used to index Notoginseng Radix(Panax notoginseng, Sanchi) cultivated in Winnan, China. The ginsenoside contents in various Sanchi on various parts and ages were quantitatively analyzed by HPLC. The average of total saponin and the ginsenoside contents of each 3-year-old Sanchi cultivated in China were higher than those of the Sanchi for longer period. As a result, the order of the total saponin contents was 3-year-old (7.13%), 4-year-old (6.27%), 5-year-old (5.34%), and 6-year-old (4.06%) Sanchi. On the other hand, the total saponin average and the ginsenoside contents of each of the fine roots, lateral roots, and rhizomes of Sanchi cultivated in China were similar to the 6-year-old Sanchi.

The substance 0116p, which exhibits cytotoxicity against human macrophage cell line THP-1, was isolated from a mycelial extract of Streptomyces scabiei subsp. chosunensis M0137. The cytotoxic substance was purified by Diaion-HP2O adsorption, solvent extraction, Sephadex LH-20 column chromatography, and silica-gel column chromatography. The molecular formula is C$\_$19/H$\_$38/O$\_$2/ (MW301.10) based on elemental and spectrometric analysis. It was identified as nonadecanoic acid by NMR spectral data. It exhibits cytotoxic activities in various human cancer cell lines, including A549, SK-OV-3, SK-MEL-2 and HCT-15. In addition, 0116p also inhibits IL-12 production in lipopolysaccharide-activated macrophages.

Resistivity changes and intermetallic growth after thermal aging of Matter tin-plated copper sheet for current collector in fuel cell were investigated to survey the diffusion of Cu into Sn in interface and surface. The results show that the intermetallic growth and resistivity depended on thermal aging temperature and dwell time. In Sn plate on a Cu substrate, $Cu_6Sn_5({\mu})$ and $Cu_3Sn({\varepsilon})$ intermetallics layer were formed at plate/substrate interface. $Cu_6Sn_5({\mu})$ intermetallics layer gradually changed $Cu_3Sn({\varepsilon})$. Moreover Cu get through Sn layer and it was diffused in the surface at $200^{\circ}C$. On the other hand, only $Cu_3Sn({\varepsilon})$ intermetallics layer were formed at plate/substrate interface at $300^{\circ}C$. Consequently, the intermetallics formation, thermal condition and oxidation of surface, causes increase in the resistivity of Tin-plated copper sheet.

Lindera erythrocarpa Makino (LE) is widely distributed on Jeju Island, where it has been used for various traditional therapies. Effects of a crude extract of LE were examined in rats with obesity induced by a high-fat diet (HFD). Anti-obesity effects were followed in rats receiving orally administered vehicle, 100mg/kg extract, or 250 mg/kg LE extract, for 56 days. LE extract (250 mg/kg) suppressed increases in body weight and epididymal fat, with amelioration of fatty changes in the liver. Additionally, serum levels of alanine aminotransferase, aspartate aminotransferase, and total cholesterol were significantly decreased compared with those of vehicle-treated groups (p < 0.05). These results suggest that oral administration of LE extract reduced rat obesity induced by HFD, possibly through the reduction of fat accumulation.

This study performed the research about the recycling basin supernatant by pre-coat filtration in the D water treatment plant at Gwangju. Choice the prompt conditions with diatomaceous earth filtration which makes contaminant reduced in the basin supernatant. Element disk of candle used in this experiment are pore size 10$\mu\textrm{m}$(R), 20$\mu\textrm{m}$(B) and 40$\mu\textrm{m}$(Y). Diatomaceous earth are cake pore size 3.5$\mu\textrm{m}$(A), 7$\mu\textrm{m}$(B) and 17$\mu\textrm{m}$(C). The filtrate concentrations were from 0.18 to 0.92$\mu\textrm{g}$/1 of Chlorophyll-a. And then, removal rate percentage were from 78.30 to 95.57(R-A). In addition SS 80%, CODMn32% COD 61%, T-N 10% and T-P 39% on the D water treatment plant. The R(40$\mu\textrm{m}$) C(17$\mu\textrm{m}$) process can be substituted of reusing the recycled water of recycling basin supernatant view of capacity and removal rate of filtrate.
