산초나무 각 부위별 알코올추출물의 피부사상균에 대한 항균활성은 근피 추출물에서 가장 높게 나타났으며, 각 용매별 분획분의 항균활성은 근피부의 petroleum ether 분획에서 가장 높게 나타났다. 항균활성성분을 분리하기 위해 항균력이 가장 높게 나타난 근피알코올추출물의 petroleum ether 분획분을 silica gel column chromatography를 실시하였으며, 항균활성성분인 CI과 CII가 분리되었다. CI과 CII의 MIC을 측정한 결과 CI의 MIC은 $40{\mu}g/m\ell$였으며, $20{\mu}g/m\ell$의 농도에서도 균액의 접종흔적이 조금 남아있었을 뿐 균사의 생장은 관찰할 수 없었다. 또한 CII의 MIC은 $800{\mu}g/m\ell$였으며, $600{\mu}g/m\ell$의 농도에서도 균액의 접종흔적이 조금 있었을 뿐 다른 농도에서처럼 균사의 생장은 관찰할 수 없었다. 기기 분석 결과 CI과 CII는 기지(旣知)의 alkaloid 화합물들이었다.

황금세기 스페인 연극의 대표적 걸작으로 평가되는 "세비야의 별"은 17세기의 대표적인 극작가인 로뻬의 비극작품이다. 그러나 이 연극은 뛰어난 작품성에도 불구하고 로뻬의 창작 진위 여부를 둘러싼 여러 논란들로 인해 스페인에서도 작품 자체에 대한 본격적인 연구는 그리 많이 이루어지지 않았다. 이에 본 연구에서는 이 연극이 가지고 있는 비극성을 크게 아리스토텔레스적 관점과 셰익스피어적 관점으로 나누어 구체적으로 살펴보고자 한다. 이 연극은 주인공들의 고귀한 사회적 신분이나 남자주인공 산초 오르띠스의 고뇌하는 적절한 대사 등 덕분에 아리스토텔레스가 말하는 카타르시스적 기능을 수행하는 데에는 별 문제가 없어 보인다. 그러나 아리스토텔레스적 비극의 핵심적 본질인 '절대적 운명에 저항하는 주인공의 자유의지'의 측면에서는 다소 문제점이 발견된다. 이 연극에는 절대적 운명을 형성하는 핵심적 장치인 하마르티아가 부재하고, 이에 따라 절대적 운명이나 운명의 불가항력성이 설정되어있지 않기 때문이다. 오히려 이 연극이 지닌 비극성은 셰익스피어적 관점에서 좀 더 온전하게 규명되어질 수 있다. 아리스토텔레스와 달리 셰익스피어는 비극성을 주인공의 성격으로부터 비롯된 것이라고 여긴다. 즉 절대적 운명과 같은 외부적 요인이 아닌 주인공 자신의 가치관과 성격으로부터 비극이 시작된다는 것이다. 실제로 이 연극의 두 가지 비극적 사건인 부스또의 죽음과 산초 오르띠스와 에스뜨레야의 이별은 불가항력적인 사건이라기보다 전횡을 휘두른 국왕 산초 4세의 비뚤어진 이기심과 욕망, 그리고 산초 오르띠스의 국왕에 대한 지나치게 맹목적인 충성심으로 인해 비롯된 것이라 할 수 있다. 즉, 절대적 권력의 부당함 앞에 궁극적으로 할 수 있는게 아무것도 없다는 무기력한 상황 그리고 이로 인한 절망감이야말로 이 연극의 비극적 결말을 목격하며 관객들이 느꼈을 비극적 감정인 것이다.

An attempt was in this to analyzer volatile flavor components of sancho(Zanthoxylum schinfolium). Essential oils in sancho tree and fruit isolated by a simulataneous steam distillation (SDE) methods using n-pentane/diethyl ether as solvent. A total of 57 and 44 components were identified by gas chromatography(GC) and combined gas chromatography spectrometry (GC-MS), respectively. Granyl acetate(29.23%) geraniol (6.80%, p-isopropyl-2-chclohexenone(5.53%), phellandral (4.10%) in sancho fruit and 4, 6, 6-trimethyl-bicyclo(7.47%), T-carvelo(4.60%, ${\alpha}$-cypernone(3.58%) in sancho tree were found to be major volatile flavor. 22 compnents including myrcene, limonene, 1, 8-cinol in sancho fruit and 10 components including 4-(1-methylethyl)-cyclohexanol, methyl undecyl ketone in sancho tree were identified. The contents of unsaturated fatty acids of palmitic acid(24.34%), myristic acid(3,68%) in sancho tree was higher than that of the sancho fruit.

Test of the optimum condition of solid phase micro extraction(SPME) was performed by use of 5 vol-atile components in dilute aqueous solution. Volatile components of Sancho(Zanthoxylum schinifolium) were isolated by SPME method and were analyzed by GC/MSD and compared with volatile compone-nts isolated by simultaneous distillation extraction (SDE) method. Total 31 components were identified by comparing gas chromatography retention time and mass spectral data. The major compounds were limonene geranyl acetate $\beta$-phellandrene phellandral mycene linalool rose oxide caproic acid and caprylic acid SPME sampling procedure was found to be a good method for qualitative analysis of the volatile components.

Yields of various solvent extracts for Zanthoxylum schinifolium and Z. piperitum leaves were higher in ethanol extract layer. Ethanol Extract in sancho and chopi leaves was fractionated with different solvents, such as hexane, chloroform, ethyl acetate, butanol and water, yields of hexane fraction was higher. In the solvent extracts using methanol, ethanol, hexane, chloroform, and water, ethanol extract showed the most effective antimicrobial activities. Ethanol extract in sancho and chopi leaves was fractionated, the most antimicrobial activities of sancho leaf were ethyl acetate fraction, and chopi leaf were chloroform fraction.

?In order to investigate effects of Zanthoxyli Fructus (Sample-A) and Fagarae mandshuricae Fructus (Sample-B), experimental study was performed through observation on isolated - ileum analgesic, hypothermal, anti-pyretic, anti-inflammatory, capillary permeability, blood flow rate, blood pressure and respiratory works. The results were as follows; 1. In spontaneous movement of mice isolated-ileum, both samples were noted to have strong inhibitory action after temporary contraction, and to show antagonism against acetylcholine chloride and barium chloride. 2. Both samples were showed to have antihistamin work on guinea pig isolated-ileum 3. In analgesic work by the acetic acid method, only Fagarae mandshuricae Fructus was proved to have significant analgesic effect in mice. 4. Both sample groups indicated anti-pyretic and anti-inflammatory effect. 5. Both samples were noted to have inhibitory effect against capillary permeability ?rise in mice. ?6. Both samples were noted to have dose-dependent falling effect on blood pressure in rabbits.

Objectives : The Zanthoxylum pericarpium has been used as oriental spicy seasoning and a medicinal plant from old times. This study was performed to determine the anti-oxidant efficacy of Zanthoxylum pericarpium extract and the anti-microbial effects. Methods : We got Zanthoxylum pericarpium extract using PSE (pressurized solvent extraction) method. The anti-microbial effect of Zanthoxylum pericarpium extract was assessed on Streptococcus mutans(S. mutans) and anti-oxidant effect of the extract was assessed by measuring DPPH radical scavenging activity and SOD like activity. Results : 1. Zanthoxylum pericarpium extract had high anti-microbial activity on S. mutans. 2. DPPH radical scavenging activity significantly increased in the Zanthoxylum pericarpium extract. 3. SOD like activity also significantly increased in the Zanthoxylum pericarpium extract. Conclusions : The PSE extract from Zanthoxylum pericarpium has good anti-microbial and anti-oxidant effects in a concentration-dependent manner.

Location awareness is an important capability for mobile-based indoor services. Those indoor services have motivated the implementation of methods that need high computational load cost and complex mechanisms for positioning prediction. These mechanisms, such as opportunistic sensing and machine learning, require more energy consumption to achieve accuracy. In this paper, we propose the Bluetooth Low Energy indoor zone detection (BLEIZOD) technique. This method exploits the concept of proximity zone to reduce the load cost and complexity. Our proposed method implements the received signal strength indicator (RSSI) function more effectively to gain accuracy and reduce energy consumption.
