  • In this paper, a partial ordering of positive quadrant dependence(PQD) for bivariate stochastic processes are introduced and basic properties and closure under certain statistical operations are derived. Examples are given to illustrate these concepts

  • Objective: SanYangSam and SanYangSanSam are traditional Korea-medical herbs that are grown from Panax ginseng C.A. Meyer. In our previous studies, we found that the functional compounds in SanYangSam and SanYangSanSam were different and depended on the type and the cultivation environment of ginseng. This study aimed to profile the functional constituents in SanYangSam and SanYangSanSam. Methods: To profile the functional aspects of the many compounds that have therapeutic activities in SanYangSam and SanYangSanSam extracts, we used liquid chromatography tandem mass spectrometry and quadrupole orthogonal acceleration time-of-flight mass spectrometry. Results: A total of four major compounds were detected; two of which were the natural flavonoids kaempferol and quercetin. Among others, two polyacetylene compounds, including panaxydol and panaxynol, were detected. Conclusion: In this study, we found that panaxydol, one of the polyacetylene constituents of ginseng, is a candidate anti-cancer agent in SanYangSam and SanYangSanSam pharmacopuncture. In addition, we found that the panaxydol levels in the SanYangSanSam extract were over 30 times those in the SanYangSam extract.

  • 조선 산학의 퇴타술의 역사를 연구한다. 이상혁(李尙爀)$(1810\sim?)$의 익산(翼算)(1868)이 출판되기 전의 역사와 익산(翼算)의 결과로 나누어 연구한다. 경선징(慶善徵)$(1616\sim?)$의 묵사집산법(默思集算法)부터 남병길(南秉吉)$(1820\sim1869)$의 산학정의(算學正義)(1867)까지의 산서를 통하여 익산(翼算) 이전의 퇴타술은 큰 발전을 이루지 못한 것을 조사한다. 이상혁(李尙爀)은 조선(朝鮮) 산학(算學)에서 가장 독창적인 방법을 써서 새로운 결과를 얻어낸다. 그는 퇴타술을 구조적으로 해결하고, 또 새로운 문제인 절적(截積)과 이를 위한 분적법(分積法)을 도입하여 이의 구조도 완전히 밝혀내었다.

  • Object : This study is designed to evaluate effects of acupuncture and herb-medication by the data of DITI(Digital Infrared Thermographic Imaging) examination and the changes of clinical symptoms after the therapy of acupuncture and herb-medication in the patients with Bell's palsy. Contents : The conservative therapy with acupuncture and herb-medication was performed during 1-8weeks. The acupuncture points of S4, S6, G14, S2, BL2, SI18, TE23, LI4 and S36 was used. In the pre- and post therapy, DITI examinations were performed in patients who had Bell's palsy and were treated by acupuncture simultaneously, and then tried to correlate the results of clinical symptoms with the difference of thermographic findings at pre-and post acupuncture. Setting : The standard routine themographic examinations were performed with thermography (DITI) in the 16 patients with Bell's palsy at pre- and post acupuncture. patients : Thermographic imaging of 16cases was analyzed. They had diagnosed Bell's palsy. They were treated by acupuncture and moxibustion therapy in Wonkwang Oriental Hospital from Jauary, 1999 to February, 2000. Results : The results of treatment showes that 56.25% of patients achieved excellent recovery and 31.25% achieved good recovery. After compairing the DITI results before and after treatment, we found 43.75% of patients achieved excellent recovery and 43.75% achieved good recovery. Conclusion :Acupuncture showed good results over 87.5% in clinical evaluation and 87.5% in DITI. Thermographic examination showes terapeutic effect of acupuncture treatment.

  • Although inflammatory mediators such as nitric oxide(NO) and pro-inflammatory cytokines are involved in host defense mechanism, these overproduction contributes to the pathogenesis of several diseases such as otitis media, hearing loss, periodontitis, bacterial sepsis, rheumatoid arthritis, chronic inflammation and autoimmune diseases. We investigate the anti-inflammatory effects of water extract from Ji-Pae-San(JPSWE) fomulated with Angelica dahurica plus Fritillaria Verticillata, Angelica dahurica(ADWE), and Fritillaria Verticillata(FUVE) in vitro and in vivo. Each extract inhibited the production of inflammatory mediators(NO, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, and prostaglandin $E_2$) and the expression of inducible NO synthase(iNOS) and cyclooxygenase-2(COX-2) in lipopolysaccharide(LPS)-stimulated RAW 264.7 macrophages in a dose-dependent manner. These inhibitory effects were synergistically increased by their combination. JPSWE also inhibited $TNF-{\alpha}$, $IL-1{\beta}$, IL-6. and $PGE_2$ production as well as COX activity in LPS-stimulated mice. Moreover, JPSWE significantly suppressed death by LPS-septic shock in mice(survival rate: 100%). These results suggest that Ji-Pae-San may be useful for therapeutic drugs against inflammatory immune diseases, probably by suppressing the production of inflammatory mediators.
