  • Failure Mode Effects and Criticality Analysis (FMECA) evaluates criticality and severity of each failure mode. Generally, those indices are determined subjectively by experts and operators. However, this process has no choice but to include uncertainty. In this paper, a method for eliciting expert opinions considering its uncertainty is proposed to evaluate the criticality and severity. In addition, a fuzzy expert system is constructed to determine the crisp value of risk level for each failure mode. The results are worth considering while deciding the proper policies for each component of the system.

  • Objectives: This study was carried out to investigate 1he effects of Sasammaickmoondong-tang(SME) on colonic mucosal lesions induced by indomethacin in mouse. Methods: The normal group is 1hat no inflammation elicitated mouse. Control group is that gastro-inflammation elicitated mouse. Sample group is that SME administered mouse after gastro-inflammation elicitation. Results: In the common morphology and histochemical change, control group was observed various injury-mucous surface cell, micro-villi, paneth cell, surface epithelial cell, goblet cell-by hemorrhagic erosion, while sample group was as same as normal group.

Methods: The normal group was no inflammation-induced mice. The control group was gastro-inflammation-induced mice. The sample group was mice administered SME after gastro-inflammation elicitation. Results: In the common morphology and histochemical change, the control group was observed with various injury-mucous surface cell, micro-villi, paneth cell, surface epithelial cell, goblet cell - by hemorrhagic erosion, while the sample group was as same as the normal group. In the immunohistochemical change, the distributions of COX-1, Bcl-2, and BrdU treated with SME were noticeably higher than in the control group (p<0.05). The distributions of TUNEL, NF-B, COX-2, IL-2R-, NK-1.1, ICAM-1, and CD11b/18 in those treated with SME were noticeably lower than in the control group (p<0.05). Finally, the distribution of SBA was the same as in the normal group.

  • 양파(노란색, 붉은색, 흰색)의 열수 추출물이 DNCB로 감작된 4주령 BALB/c mouse 암컷에 유도된 접촉성 피부염의 억제효과를 조사하였다. 림프절, 비장 및 흉선의 무게는 양파 투여군이 DNCB 대조군보다는 낮게 나타났다. 양파 추출물을 투여한 군에서 귀의 무게는 양파 추출물의 농도가 높을수록 감소하는 경향을 보였으며, 대조군과 비교하여 무게에 함량 변화가 있었다. 양파추출물을 1,000 mg/kg 농도로 투여하면 귀의 무게는 대조군과 유사한 수준까지 낮아졌으며, 귀의 두께는 양파추출물을 투여한 군에서 시간이 경과할수록 두께가 감소하는 경향을 나타내었다. MDA 함량은 DNCB대조군과 양파 투여군을 비교하였을 경우에, 간 조직에서 차이가 나타나지 않았으나, 염증이 발생한 귀 조직에서는 차이가 나타났으며, NO 함량은 모든 양파그룹에서 염증이 억제되어 대조군에 유사하게 측정되었다.

  • Objectives : This study was carried out to investigate the effect of Samooltang (SMT) on the injury of gastric mucous membrane by ethanol in mice. Methods : The normal group was mice with no inflammation. The control group was mice with gastro-inflammation elicited by ethanol. The sample group was SMT-administered mice before gastro-inflammation elicitation. Results : In the immunohistochemical change, the distribution of SBA and COX-1 treated with SMT noticeably increased over the control group (p<0.05). The distribution of NF-κB P50, COX-2, and TUNEL treated with SMT noticeably decreased over the control group (p<0.05). The distribution of SMT was the same as the normal group. Conclusions : According to the above results, it is supposed that SMT would be helpful against gastritis and gastric ulcer caused by alcoholic drinks.

  • 일반적으로 현업에서 통합테스트 시나리오를 작성하는 개발자는 개발 단계의 이슈와 그들만의 요구사항을 테스트시나리오에 포함하는 경향이 있다. 즉 설계 단계에서 중요시 되던 사용자 요구 사항이나 우회 흐름과 같은 이슈들은 빠지기 쉽다. 이번 연구에서는 통합 테스트 시나리오 작성시 상태전이기법과 같은 테스트 설계 기법을 사용하여 개발자가 빠뜨리기 쉬운 설계 단계에서의 사용자 요구 사항과 같은 항목들이 고려되는 통합 테스트 시나리오를 도출하는 방법을 제시하였다. 이 방법을 활용한 결과 생각하지 못했던 테스트 케이스와 테스트 시나리오를 도출 할 수 있었고, 이로 인해 높은 만족도를 얻을 수 있었다.

  • To develop systems for economic production of useful essential oil compounds, callus was induced from the seedlings of Agastache rugosa and cultured on MS medium. The volatile oil fraction was extracted from the callus and investigated by mean of GC-MS. The composition of the oil was compared with that of the mother plant. As a result, sixty five compounds including ferruginol were identified in the essential oil fraction. The main component of the oil from the leaves of Agastache rugosa was methyl chavichol (53.6%). Methyl jasmonate and jasmonic acid were added to the culturing cell suspension, separately and the composition of induced oil were compared. The oils from cultured cells treated with jasmonates showed considerably different patterns. Especially, the peak of estragole was found in callus oil after treatment with methyl jasmonate as though the amount was limited to 0.58%. In general, the TIC pattern of GC-MS of the callus oil became more similar to the oil from the leaves after elicitation.

  • Cell cultures of Cayratia trifolia (Vitaceae), a tropical lianas, were maintained in Murashige and Skoog's medium containing $0.25mg\;1^{-1}$ NAA, $0.2mg\;1^{-1}$ kinetin and casein hydrolysate $250mg\;1^{-1}$. Cell suspension cultures of C. trifolia accumulate stilbenes (piceid, resveratrol, viniferin, ampelopsin), which on elicitation by any of $500{\mu}M$ salicylic acid, $100{\mu}M$ methyl jasmonate, $500{\mu}M$ ethrel and $500mg\;1^{-1}$ yeast extract, added on the 7th day, were enhanced by 3- to 6-fold ($5-11mg\;1^{-1}$) by the 15th day.

  • The purpose of this paper is to measure the benefits of conservation of the green belt in the Greater Seoul area by CVM using dichotomous choice with a follow-up elicitation method. According to the government's plan, part of the green belt in the Greater Seoul area is to be freed from green belt designation. The mean willingness-topay(WTP) to conserve the green belt in the current state turns out to be about 7,430 won(95% confidence interval 6,220 - 8,640 won) per household, which amounts to 308 billion won per year for entire population of Seoul. This WTP figure is found to be significantly influenced by level of education, sex, and the variables related to the perception and attitudes of respondents.
