  • 계산을 통한 단백질 상호작용 예측 기법의 중요성이 제기되면서 많은 단백질 상호 작용 예측 기법이 제안되고 있다. 하지만 이러한 기법들이 일반 사용자가 손쉽게 사용할 수 있는 서비스 형태로 제공되고 있는 경우는 드물다. 본 논문에서는 현재까지 알려진 단백질 상호작용 예측 기법 중 예측 기법의 완성도가 높고 상대적으로 예측 정확도가 높은 것으로 알려진 도메인 조합 기반 단백질 상호 작용 예측 기법을 PreSPI(Prediction System for Protein Interaction)라는 서비스 시스템으로 설계하고 구현하였다. 구현된 시스템이 제공하는 기능은 크게 도메인 조합 기반 단백질 상호 작용 예측 기법을 서비스 형태로 만들어 제공하는 기능으로 입력 단백질 쌍에 대한 상호작용 예측이 중심이 된 핵심기능과, 핵심 기능으로부터 파생되는 기능인 부가 기능, 그리고 주어진 단백질에 대한 도메인 정보검색 기능과 같이 단백질 상호작용에 관하여 연구하는 연구자에게 도움이 되는 일반적인 기능으로 구성되어 있다. 계산을 통해 단백질 상호 작용을 예측하는 시스템은 대규모계산이 요구되는 경우가 많아 좋은 성능을 갖추는 것이 중요하다. 본 논문에서 구현된 PreSPI 시스템은 서비스에 따라 적절히 그 처리를 병렬화 함으로써 시스템의 성능 향상을 도모하였고, PreSPI 가 제공하는 기능을 웹 서비스 API 로 Deploy 하여 시스템의 개방성을 지원하고 있다. 또한 인터넷 환경에서 변화되는 단백질 상호 작용 및 도메인에 관한 정보를 유연하게 반영할 수 있도록 시스템을 계층 구조로 설계하였다. 본 논문에서는 PreSPI 가 제공하는 몇 가지 대표적인 서비스에 관하여 사용자 인터페이스를 중심으로 상술함으로써 초기 PreSPI 사용자가 PreSPI 가 제공하는 서비스를 이해하고 사용하는 데에도 도움이 되도록 하였다.있어서 자각증상, 타각소견(他覺所見)과 함께 이상(異常)은 확인되지 않았으며 부작용도 없었다. 이상의 결과로부터, ‘펩타이드 음료’는 경증고혈압 혹은 경계역고혈압자(境界域高血壓者)의 혈압을, 자각증상 및 혈액${\cdot}$뇨검사에도 전혀 영향을 미치지 않고 저하시킨다고 결론지었다.이병엽을 염색하여 흰가루 병균의 균사생장과 포자형성 등을 관찰한 결과 균사가 용균되는 것을 볼 수 있었으며, 균사의 용균정도와 분생포자형성 억제 정도는 병 방제효과와 일치하는 경향을 보였다.을 의미한다.

  • Many studies have done on Egyptian Clothing because its unique characteristic culture. However, I was facinated by the exhibitions of Tutankhamen burial treasures which were shown in San Francisco and New York in 1978 and 1979. I found out myself that there are several interesting aspects of clothing to compare 18th dynasty king, Tutankhamun and other dynasties in Egyptian culture. Therefore, I tryed to analized the Egyptian clothing including accessaries with theigr symbols durin 18th dynasty King, Tutankhamun. The most of people were shocked and amazed when they toured the exhibition of Tutankhamun articles which were the most incredible burial treasures in existence today. The body of the King has been embalmed, bandaged and fitted in eight layers of coffins with pure gold mask to represent the god Osiris. Among eight layers of coffins, one is pure solid gold in mummiform, two of mummiforms are made of compact wood covered with sheets of gold and inlaid with multi-colored glass-paste and semi-precious stones. The Egyptian belived that the soul continued to exist throughout eternity if it had passed on examination of its deeds on earth at a "Last Judgement" presided over by Osiris. They also believed that the mummified body could exist in the tomb as a habitation that the soul could revisited. Thus a proper burial was vital for a full existence in the hereafter. They buried dead person in the sealed vault of the tomb with some of the possessions he had used during his life time, such as his furniture, clothing and jewels. In this studies, I've tried to research to various clothings, and accessories with their symbols used during 18th dynasty king, Tutankhamun. The studies are shown as: I) Clothings of Tutankhamun dynasity of Kalasiris, Sheath skirt. Gala skirt, Loin skirt, Hike and Dalmatic. The Dalmatic was first seen in this dynasty. Probably the Roman Christian borrowed the Dalmatica from Egyptian Dalmatic. No where has the same design at the period. II) Egyptian of 18th dynasty Tutankhamun wore big headdress, broad collar necklace passium, pendants, armlets, rings and earrings with very beautiful, exquisite handcraft. They seem the first people who wore earrings in Egyptian history. III) The symbols of decorated items vulture, lotus...Upper Egypt Uraeus, papyrus...Lower Egypt scaravaeus, Nile Riber...rebirth man(Ankh), +...eternal life solar disc, gold...sun ostrich-feather...nobleness God, Horus' eye...protection against enemy IV) Also Egyptian prefered the straight line and a right angle which were the basic principles of architectural arrangement.

  • The antimicrobial activity of 10 different traditional medicinal herbs extracts against E. coli was determined using paper disc method. Caesalpinia sappan and Rhus javanica, extracts in 5 mg/ml, and Paeonia suffruticosa and Seutellaria baicalensis extracts in 10 mg/ml showed significant antimicrobial activity against E. coli. Minimum inhibitory concentrations of medicinal herbs extracts were in the range of $1.4{\sim}8mg/ml\;and\;1.2{\sim}12mg/ml$, for MeOH extracts and EtOH extracts, respectively. In addition, the antimicrobial activity of each solvent fraction was most significant with the EtOAc layer. Optical density at 620nm after 24 hours incubation of E. coli in the presence of 100, 300 or 500 ppm of Caesalpinia sappan extract ranged from 0.02 to 0.1 compared to 0.6 in the absence of Caesalpinia sappan extract, indicating that growth of E. coli was significantly inhibited within 24 hours by the addition of at least 300 ppm of Caesalpinia sappan extract. Optical density at 620 nm after 24 hours incubation of E. coli in the presence of 300 ppm of Rhus javanica extract ranged from 0.02 to 0.2 compared to 0.5 in the absence of Rhus javanica extract, indicating that growth of E. coli was also significantly inhibited within 24 hours by the addition of at least 500 ppm of Rhus javanica extract. In conclusion, these findings suggest that extracts from medicinal herbs may play important roles in antimicrobial activities against E. coli.

  • Objective : Spondylothesis is a disease which sagittal facet of vertebral body's invariable alignment is being broken and vertebral body being pushed forward. Main pattern of spondylothesis is isthmic spondylothesis by isthmus defect or fracture, degenerative spondylothesis occurred by desiccated change of intervertebral disc or vertebral condyle joint's ligament. The purpose of this study is to assess the difference of the Pelvic angles, Lumbosacral angles, Pelvic tilt, and Lumbar lordotic angles of the spondylothesis patients. Methods : We analyzed the lateral view of lumbar spine of 49 isthmic spondylothesis patients, 45 degenerative spondylothesis patients and 26 patients who haven't been diagnosed as vertebra disease. We investigated each patient's pelvic angle, lumbosacral angle, pelvic tilt and lumbar lordotic angle. Results and Conclusion : 1. Pelvic incidence, in cases of degenerate spondylothesis patients, is higher than spondylothesis patients but shows less significance. On the contrary significance is higher than the group haven't been diagnosed as vertebra disease. 2. Lumbosacral incidence, in cases of isthmic spondylothesis patients, shows higher significance than degenerative spondylothesis patients and the group haven't been diagnosed as vertebra disease. 3 Pelvic tilt, in cases of degenerative spondylothesis patients, shows higher significance than isthmic spondylothesis patients and the group haven't been diagnosed as vertebra disease. 4. Lumbar lordotic angle, in cases of isthmic spondylothesis patients, shows higher significance than degenerative spondylothesis patients and the group haven't been diagnosed as vertebra disease. 5. Degenerative spondylothesis patient shows specific impression, a forwardly moved high femoral axial and as a result of large lumbrosacral angle and lumbar lordotic angle shows specific impression, an increased weight pressure on sacrum.

  • In order to modify lipid production of Perilla qualitatively as well as quantitatively by genetic engineering, genes involved in carbon metabolism were isolated and characterized. These include acyl-ACP thioesterases from Perilla frutescens and Iris sp., four different $\beta$-ketoacyl- ACP synthases from Perilla frutescens, and two $\Delta$15 a-cyl-ACP desaturases(Pffad7, pffad3). Δ15 acyl-ACP desa turase (Δ15-DES) is responsible for the conversion of linoleic acid (18:2) to $\alpha$-linolenic acid (ALA, 18:3). pffad 3 encodes Δ15 acyl-desaturase which is localized in ER membrane. On the other hand, Pffad7 encodes a 50 kD plastid protein (438 residues), which showed highest sequence similarity to Sesamum indicum fad7 protein. Northern blot analysis revealed that the Pffad7 is highly expressed in leaves but not in roots and seeds. And Pffad3 is expressed throughout the seed developmental stage except very early and fully mature stage. We constructed Pffad7 gene under 355 promoter and Pffad3 gene under seed specific vicillin promoter. Using Pffad7 construct, Perilla, an oil seed crop in Korea, was transformed by Agrobacterium leaf disc method. $\alpha$-linolenic acid contents increased in leaves but decreased in seeds of transgenic Perilla. Currently, we are transforming Perilla with Pffad3 construct to change Perilla seed oil composition. We isolated three ADP-glucose pyrophosphorylase (AGP) genes from Perilla immature seed specific cDNA library. Nucleotide sequence analysis showed that two of three AGP (Psagpl, Psagp2) genes encode AGP small subunit polypeptides and the remaining (Plagp) encodes an AGP large subunit. PSAGPs, AGP small subunit peptide, form active heterotetramers with potato AGP large subunit in E. coli expressing plant AGP genes.

  • The antibacterial activities of nine oriental herbal medicine extracts were measured against seven kinds of bacteria known to cause food poisoning and disease. The extracts were prepared with distilled water using an autoclave ($121^{\circ}C$ for 30 min). The extraction yields of nine oriental herbal medicines were in the rage of 0.5%-33.4%. The antibacterial activities were evaluated using the paper-disc method. Extracts of Hwangryeon, Jiyu, and Ohbaeja showed antibacterial activities while the others did not. Extracts of Coptis japonica, Hwangryeon, and Sanguisorba officinalis, Jiyu showed antibacterial activities only against Clostridium perfringens and Listeria monocytogenes. Extracts of Rhus javanica, Ohbaeja showed the strongest antibacterial activities against all the bacteria tested. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of R. javanica extracts were in the range of 2.4~20 mg/ml for the bacteria tested. In conclusion, the extract of R. javanica showed superior antibacterial activities against the seven bacterial strains tested. The MIC and MBC values for each bacterium were represented as strain names (MIC, MBC), which were Bacillus cereus (11.2, 20), Clostridium perfringens (2.4, 4.7), Escherichia coli (9.1, 9.1), Listeria monocytogenes (11.1, 20), Salmonella typhi (4.7, 9.1), Staphylococcus aureus (2.4, 4.7), and Vibrio parahaemolyticus (2.4, 5.3). Further purification and study of this antibacterial material would be helpful for developing antibiotics or promoting synergistic effects with known antibiotics, producing antibacterial material for lengthening the shelf-life of food, and so on.

  • Thermal properties of PP and LLDPE dusts from chemical plant and their risks of coexisting with oxidizer were investigated by a pressure vessel. The thermal decomposition of PP and LLDPE dusts with temperature using DSC and the weight loss with temperature using TGA were also investigated to find the thermal hazard of PP and LLDPE dusts. Using the pressure vessel which can estimate ignition and explosion of PP and LLDPE dusts coexisting with oxidizer, a series of bursting of a rupture disc, experiments has been conducted by varying the orifice diameters the weight ratio of the sample coexisting with oxidizers and the species of oxidizer. And fire gases was measured by gas analyser ($ECOM-A^+$). According to the results of the thermal analysis of PP and LLDPE dusts, the decomposition temperature range of PP and LLDPE dusts was 200 to 350 and 300 to $500^{\circ}c$, respectively. The risk of PP and LLDPE dusts coexisting with oxidizer was increased as the orifice diameter was decreased. On the other hand, it was increased as the weight ratio of the sample to the oxidizer were increased. In addition, the risk of PP and LLDPE dusts coexisting with oxidizer was affected by the decomposition temperature of the sample and oxidizer. It is found that the risk of fire becomes high when the decomposition temperature of the sample is about same as that of oxidizer. Also, the fire gases was occurred carbon monoxide and carbon dioxide. The amount of carbon monoxide generated was found to be much higher in PP decomposition than in LLDPE due to incomplete combustion of PP which has high content of carbon in chemical compound.

  • Eriobotrya japonica has been used as a folk medicine for treatment of skin diseases, inflammation, coughing, phlegm, and ulcers in Korea and other Asian countries. In a search for possible bioactive agents from natural sources, we found that the methanolic extracts from various parts of E. japonica showed moderate antioxidative and antimicrobial activities in several in vitro bioassay systems. Additionally, the respective parts of E. japonica were irradiated at 20 kGy to investigate the effects of irradiation. Gamma irradiation of E. japonica extracts removed the deep greenish color without affecting its natural biological activities such as its antioxidative and antimicrobial properties. Based on these findings, the methanolic extracts of this plant source may be not affected by gamma irradiation as its bioactive constituents may be insensitive to this irradiation. Moreover, the methanolic extract of E. japonica may serve as a good natural resource for beneficial functions in food and other related industries.

  • Rock bolts have been installed into rockmass as a main support system. In order to evaluate the rock bolt integrity using non-destructive technique, the transmission method of the guided ultrasonic wave has been successfully performed. For the transmission method, however, the source for the generation o# guided ultrasonic waves should be installed at the end of the steel bar during construction of the rock bolt in the field. The purpose of this study is to suggest a reflection method that the source and the receiver are installed on the head of the steel bar. The reflection method is compared with the transmission method using non-embedded rock bolts and rock bolts embedded in concrete block. In this experiment, the piezo disc element is used as the source and the AE sensor is used as the receiver. The wavelet transform is applied to determine the energy velocity. The experimental studies show that the reflection method produces almost identical value of the transmission method, and the energy velocity increases with the defect ratio. This study suggests that the reflection method of the guided ultrasonic wave may be a suitable method fur the rock bolt integrity evaluation in the field.

  • Beak trimming in laying hens is a routine practice in which about 1/3-1/2 of the upper and lower beak is removed with the aim of reducing cannibalism. This experiment aimed to identify if this procedure causes pain by examining self-administration of an analgesic (carprofen) and pecking behaviour in 80 laying pullets beak-trimmed by two different methods at one day of age using hot-blade cauterisation or infra-red cauterisation. We also tested a control treatment, pullets with intact beaks, and a positive control treatment of pullets beak trimmed at 10 weeks of age which were expected to experience some pain due to recent severing of the underlying nerves in the beak. At 11 weeks of age birds trimmed at 10 weeks of age pecked more (p<0.001) gently ($0.6{\pm}0.06N$) at a disc attached to a force-displacement transducer than birds trimmed at 1 day of age with an infra-red machine ($0.9{\pm}0.1N$) or a hot blade ($1.1{\pm}0.07N$) and intact birds ($1.2{\pm}0.1N$). Maximum force of pecks recorded was also lower (p<0.001) in birds trimmed at 10 weeks of age than birds trimmed at 1 day of age with an infra-red method or a hot blade and intact birds. However, the pecking force in birds trimmed at 10 weeks of age was not increased by providing them with analgesic-treated feed, though birds that ate more carprofen had a higher maximum force of peck (p = 0.03). Pecking force in birds beak-trimmed at 1 day of age was the same as the pecking force of intact birds, and was unaffected by feeding pullets carprofen. A method of self-administration of an analgesic had previously revealed that chickens in neuromuscular pain arising from lameness consumed more of a feed containing carprofen than healthy chickens. However, we found no evidence that beak-trimmed pullets consumed more carprofen-treated feed than pullets with an intact beak. It should be noted that the three beak trimming methods resulted in an average 34% reduction in beak length, considered a light trim, and is perhaps not representative of commercial birds where greater portions of the beak are removed. We conclude that although carprofen has been reported to have an analgesic effect on neuromuscular pain in chickens, it appears to have no analgesic effect on potential neuropathic pain arising from the nerves severed by a light beak trim.
