<P>Since antiquity, medical herbs have been prescribed for both treatment and preventative purposes. Herbal formulas are used to reduce toxicity as well as increase efficacy in traditional Korean medicine. <I>U-bang-haequi tang</I> (UBT) is a herbal prescription containing <I>Arctii fructus</I> and <I>Forsythia suspensa</I> as its main components and has treated many human diseases in traditional Korean medicine. This research investigated the effects of UBT against an acute phase of inflammation. For this, we measured induction of nitric oxide (NO) and related proteins in macrophage cell line stimulated by lipopolysaccharide (LPS). Further, paw swelling was measured in carrageenan-treated rats. Carrageenan significantly induced activation of inflammatory cells and increases in paw volume, whereas oral administration of 0.3 or 1 g/kg/day of UBT inhibited the acute inflammatory response. In RAW264.7 cells, UBT inhibited mRNA and protein expression levels of iNOS. UBT treatment also blocked elevation of NO production, nuclear translocation of NF-<I>κ</I>B, phosphorylation of I<I>κ</I>-B<I>α</I> induced by LPS. Moreover, UBT treatment significantly blocked the phosphorylation of p38 and c-Jun NH2-terminal kinases by LPS. In conclusion, UBT prevented both acute inflammation in rats as well as LPS-induced NO and iNOS gene expression through inhibition of NF-<I>κ</I>B in RAW264.7 cells.</P>

Objective: 본 연구는 웹 기반의 컨텐츠 관리 시스템(Contents Management System; CMS)에 관한 사용성 평가방법을 제안하고, 해당 제품 영역에서 발생할 수 있는 사용성 이슈를 규명하기 위해 수행되었다. Background: 웹 컨텐츠의 비중이 점차 늘어남에 따라, 이를 효과적으로 구축/관리할 수 있는 CMS에 대한 관심 또한 증가하고 있다. 최근에는 홈페이지 저작 도구, 웹사이트 관리 등 다양한 기능들이 CMS에 통합 되었으며, 작업방식에 있어서는 웹 기반의 협업을 지원하는 방향으로 변화하고 있다. 이로 인해 이전에 비해 다양한 사용자가 각기 다른 역할과 권한을 가지고 CMS를 사용하게 되었으나, 변화한 CMS 사용 환경을 고려한 사용성 평가 방법은 부재하는 실정이다. 이에 본 연구는 오늘날의 웹 환경을 고려한 CMS의 사용성 평가 방법론을 제작하고자 하였다. Method: 이를 위해 기존의 사용성 원칙과 소프트웨어 사용성 평가 방법론에 대한 연구를 수집하여 CMS에 적합한 사용성 평가 체계를 수립하였으며, 개발 중인 CMS에 대해 휴리스틱 평가와 사용자 실험을 수행하였다. Results: 연구 결과, 다양한 사용자들이 CMS를 이용함에도 불구하고 현재의 시스템은 개발자 위주로 설계되어 있음을 확인할 수 있었으며, 이로 인해 학습용이성과 유연성에 있어서 상당수의 문제점이 발생함을 확인하였으며, 관련된 사용성 이슈와 디자인 제언을 도출하였다. Conclusion: 본 연구를 통해 웹 컨텐츠 저작 및 관리에 있어 최근의 변화된 관점을 반영한 사용성 평가 방법론이 수립되었으며, 이를 통해 웹 관리 도구의 특성이 반영된 사용성 이슈를 진단할 수 있었다. Application: 또한, 본 연구를 통해 다양한 사용자들이 사용하는 시스템의 사용성에 대한 고찰과, 보다 유용하고 사용하기 편한 협업 도구 및 컨텐츠 관리 시스템 설계에 대한 기여가 이루어질 것으로 기대한다.

This study was carried out to investigate effects of crude protein (CP) levels in total mixed rations (TMR) on growth performance and meat quality in growing Korean black goats. Thirty-six 6-month-old growing black male goats (initial body weight =17.95${\pm}$0.13 kg) were used. The goats were randomly divided into four treatments and 9 animals were allotted to each treatment. In terms of treatments, CP levels in TMR were 14, 16, 18, and 20% of dry matter (DM) and all diets were isocaloric (2.4 Mcal ME/kg DM). The experiment lasted for 20 weeks with a 15-day adaptation period. After the end of the trial, five goats from each treatment were slaughtered to measure carcass characteristics and meat quality. Average daily gain (ADG) significantly (p<0.05) increased as dietary CP levels increased, but the highest ADG was found on the 18% CP treatment. The higher CP levels in TMR significantly (p<0.05) decreased feed conversion ratio, but the lowest ratio was on the 18% CP treatment, suggesting a higher bioavailability of nutrients by balanced energy and protein levels on this treatment. There was no significant difference in dressing percentage among treatments, but there was a tendency for levels more than 16% CP in TMR to have a comparatively higher dressing percentage than the 14% treatment. The percentages of meat, fat and bone were not significantly influenced by dietary CP levels. Dietary CP levels did not influence chemical composition of goat meat. Furthermore, there was no significant difference among treatments in any of the sensory parameters except for tenderness. Tenderness was similar for 18 and 20% treatments, which were significantly (p<0.05) higher than the 14% treatment. The results from this study suggested that an adequate CP level in TMR for achieving optimal growth performance and meat quality of growing Korean black goats might be 18% of DM, and that dietary CP level above 18% seemed not to further increase growth performance and meat quality.

본 실험에서는 우분과 볏짚의 혼합수준을 달리하여 지렁이 먹이로 이용하였을 때, 지렁이 생육과 증식에 미치는 영향과 분립의 생산량 및 화학적 조성을 조사하여 우분의 효율적인 Vermicomposting의 기초자료로 이용하고자 실시하였다. 그 결과를 요약하면 다음과 같다. 먹이의 C/N율은 20.4∼28.2로 볏짚 수준이 증가함에 따라 C/N율도 높아졌으며 실험기간 동안 지렁이의 생존율은 98.4∼99.2%로 나타났다. 산자수는 볏짚을 30과 40% 혼합한 구에서 각각 868와 906 마리로 우분 100%구의 769 마리보다는 유의하게 높게 나타났다 (P<0.05). 산자중은 8∼11.8g으로 볏짚 혼합 수준이 높을수록 유의하게 높아져 볏짚 40% 혼합구가 가장 높았다 (P<0.05). 분립생산은 볏짚 혼합 수준이 높을수록 낮게 나타났으며 소화량은 이와는 반대로 볏짚 혼합 수준이 높을수록 유의있게 높게 나타났다. This study was conducted to develop efficient vermicomposting using of different mixture ratio of the rice straw and cow manure by feeding these to earthworms and then by studying the growth and reproductive efficiency of earthworms, and the chemical composition of worm cast and its production. The results are summarized as follows. C/N ratio of feed was 20.4∼28.2 and it increased according to the higher proportion of rice straw and survival of earthworm was 98.4∼99.2%. Number of young worms were significantly higher in 30 and 40% addition of rice straw (number of 868 and 906) than number of 769 of real cow manure treatment (P<0.05). Fresh weight of young worms was 8∼11.8g and it was significantly higher in 40% addition of rice straw than other treatments (P<0.05). The cast production of earthworm was in the tendency of becoming higher according to higher ratio of rice straw but digested matter were significantly higher in 10∼40% addition of rice straw than real cow manure treatment (P<0.05).

본 연구는 톱밥의 혼합비율을 달리한 돈분을 대상으로 부숙기간별 이화학적 변화를 측정하고 이를 바탕으로 생존율을 조사하여 가축분의 효율적인 vermicomposting의 기초자료로 이용하고자 실시하였다. 그 결과를 요약하면 다음과 같다. 부숙이 경과함에 따라 지렁이가 생존하기 시작하여 8주부터 A구(돈분 100%)를 포함한 모든 구에서 지렁이의 생존이 가능하였다. C/N비는 부숙이 경과함에 따라 낮아졌으며, 톱밥혼합 비율이 높을수록 C/N비가 유의하게 높아 톱밥첨가 40인 E구가 다른구 보다 유의하게 높았다(P<0.05). 지렁이가 생존하기 시작한 C/N비는 10.8~16.0으로 나타났다. 톱밥 혼합비율을 달리한 돈분의 pH 변화는 부숙이 경과함에 따라 점차 pH 7.5에 가까워지는 경향을 보였으며 지렁이가 생존하기 시작한 pH는 7.5~8.0으로 나타났다. Ec의 변화는 부숙 경과에 따라 거의 없었으며, 처리구간에서는 톱밥첨가가 많을수록 낮아졌으며 지렁이가 생존하기 시작한 Ec는 2.2~4.7mS/㎝으로 나타났다. This study was performed to investigate the effect of different mixture ratio of the sawdust and swine manure and to measure C/N ratio, ph, Ec of the ripening of that and investigate on survival of earthworm with that and to use to efficient vermicomposting of swine manure as basic information. The results are summarized as follows. According as ripening of different mixture ratio of the sawdust and swine manure, earthworm begins to exist and survival of earthworm is possible in all including A(swine manure 100%) since 8 weeks. According as ripening, C/N ratio became low and sawdust mixing ratio is high. C/N ratio is significantly higher in E(sawdust 40%) than A, B, C and D(P< 0.05). C/N ratio that earthworm begins to exist appeared by 10.8∼16.0. pH value change of looked tendency that approach to pH 7.5 gradually according as ripening. pH value that earthworm begins to exist appeared by 7.5∼8.0. Electrolytic conductivity became low sawdust addition ratio is high. Electrolytic conductivity that earthworm begins to exist appeared by 2.2∼4.7mS/㎝.
