The purpose of this paper is the study on the architectural characteristics revived from the roman architecture, focused on the early renaissance architecture building. The results of study are as follow:
1. The composition system of Domus which is formed of urban house in the Roman period is presented by spatial arrangement of palace architecture centering around atrium in the Renaissance period. Thus plan type of Domus is used by atrium form which is composed of peristyle from the palace and villa in the Renaissance period.
2. The circular temple in the Roman period is composed of element such as podium, stair, peristyle centering around the basic circular plan. Bramante planed to revive above elements for the Tempietto to concept from the circular temple in the Roman period.
3. The triumphal arch in the Roman period is strong monument to the independent building in the city, but thus arch is used of church facade as the important example which is composed with building elevation in the Renaissance period.
4. The composition system and element of Roman temple which is planned to rectangular plan is composed of high podium, stair, portico, prostyle and pediment. The facade plan of church is used by the partial elements and total elements perfectly from the temple in the Roman period.
5. The linearly successive and repetitive composition which is composition system and element of aqueduct arches of same dimension shows to the palace facade, arcade for gallery space and side elevation plan of S.Francesco church.
6. Such as background of Colloseum, Rucellai palace can be called good example which is created by the new architectural form to the creative starting point from the classical architecture from.
현재 기업에서는 제품인증과 경영시스템인증의 신뢰성 확보가 중요한 과제이다. 이는 제품개발 중심에서 제품 및 프로세스의 통합 개발 중심으로 연구의 필요성을 제시 해주고 있다. 따라서, 정적인 제품인증에서 동적인 시스템인증의 필요성이 대두되면서 신뢰성경영시스템(DMS; Dependability Management System; IEC60300)이 요구되어진다. 제품개발의 프로세스에서 발생되는 신뢰성 문제점들을 해결하기 위하여 트리즈(TRIZ ; Theory of Inventive Problem Solving) 기법을 활용하였다. 본 연구에서는 창의적 문제해결 방법론인 트리즈기법을 활용하여 신뢰성경영시스템에서 제품 및 프로세스 통합개발(IPPD; Integrated Product and Process Development)을 하고자 한다. 결과적으로 창의적 신뢰성경영시스템(CDMS; Creative Dependability Management System)을 제품 및 프로세스 통합개발 모델로 제시한다.
전 세계적으로 이상 고온, 폭우, 가뭄, 지진, 해일 등이 빈번하게 발생하고 있다. 그 피해 규모도 앞으로 계속 커질 전망이다. 경제활동의 주체인 기업이 이러한 자연 재해로 인하여 지속적이고 안정적으로 운영되지 못하게 된다면 이는 기업자체는 물론 치 열한 글로벌 경쟁체제 속에서 국가경쟁력향상에 상당한 타격을 줄 수 있다. 하지만 우리나라의 기업은 선진국에 비해 상대적으로 자연재해 발생 시 체계적인 방재시스템을 구축하지 못하고 있다. 본 논문에서는 자연재해저감기술 개발의 필요성과 선진국가의 사례들을 통한 우리나라의 자연재해저감기술이 나아갈 방향성을 모색하고자 한다.
Micro-scale copper bumps for build-up PCB were electroplated using a pulse-reverse method. The effects of the current density, pulse-reverse ratio and brightener concentration of the electroplating process were investigated and optimized for suitable performance. The electroplated micro-bumps were characterized using various analytical tools, including an optical microscope, a scanning electron microscope and an atomic force microscope. Surface analysis results showed that the electroplating uniformity was viable in a current density range of 1.4-3.0 A/dm2 at a pulse-reverse ratio of 1. To investigate the brightener concentration on the electroplating properties, the current density value was fixed at 3.0 A/dm2 as a dense microstructure was achieved at this current density. The brightener concentration was varied from 0.05 to 0.3 ml/L to study the effect of the concentration. The optimum concentration for micro-bump electroplating was found to be 0.05 ml/L based on the examination of the electroplating properties of the bump shape, roughness and grain size.
For biological control of larva of Cnaphalocrocis medinalis and Naranga aenescens do considerable damage to crops by folding and scraping the leaf tissue of rice, a large number of Bacillus thuringiensis isolates have been obtained from soil samples in Korea and the pesticidal activity was assayed against two insect pest species described above. Among 53 Bt isolates tested in bioassay, 18 and 13 isolates showed over 90% mortality against C. medinalis and N. aenescens, respectively. Some isolates (11 isolates including CAB141) presented dual activity against C. medinalis and N. aenescens. These isolates showed over 96% control effect in pest control in laboratory against larvae of C. medinalis. Also, it was investigated that pupation, pupal length, and adult emergence of larvae exposed to Bt suspension decreased. Especially, the pupal length of C. medinalis after being fed corn seedling leaves treated Bt suspension for 10 days, were much smaller than that of control.
It is not easy for porcine embryos produced by in vitro systems to develop into blastocysts with high quality. To solve this problem, many researchers have developed novel culture methods. However, the formation of blastocysts with high quality is still low. In this study, we aimed to produce piglet following transfer of in vitro produced early embryos ( cell stage embryos) or morula and blastocyst. The cell stage embryos were transferred to five estrus-synchronized recipients (200 embryos per recipient). One of the five sows farrowed three piglets, which contain two live piglets and one dead piglet, 114 days after embryo transfer. However, two recipients transferred with morula and blastocysts did not farrow. Microsatellite analysis confirmed that the genomic DNA of two live piglets were not genetically identical to that of the recipient. These results indicate that it is possible to obtain piglets by transfer of early embryos produced by in vitro production (IVP) systems.
The kairomonal activity of the aggregation pheromones of Riptortus clavatus for the egg parasitoid, Gryon japonicum , were investigated in soybean field. The parasitism rate of G. japonicum gradually decreased when the distances between pheromone traps and egg sites were increased from 0 to 15 m. The active distance of pheromone source for parasitoid attraction was estimated to be ca. 15 m. Under field conditions, the parasitoid wasp population peaked during the late August and early September, and the parasitism rate increased when the number of pheromone traps was increased from one to three per 165 ㎡. However, insecticide-treated plots, the level of parasitism recorded is relatively low. Sex ratios in field populations of G. japonicum were female-biased.
This study was performed to investigate the seasonal occurrence, developmental characteristics of each nymphal stages with different temperatures (20, 25, 30℃), longevity and fecundity of ussur brown katydid, Paratlanticus ussuriensis, damaging by outbreaks in the orchard areas of Bitan-ri, Yeongdong, Chungbuk. Paratlanticus ussuriensis occurred from late-March to late-August with peak of mid-May. Newly emerged nymphs appeared from March and do damaged fruit orchards with peak of mid-May when P. ussuriensis existed as 4th and 5th nymphal stages. P. ussuriensis adult occurred from early-June to mid-Aug. with peak of mid-July. Total density of P. ussuriensis was showed highest in mid-May. Paratlanticus ussuriensis goes through nymphal stages to 7th nymph, the ovipositor began exposed to outside from the 4th instar and the body weight increased heavily from this stage and the wings were observed from 6th instar. Developmental period was longer as increased the nymphal stages. Sex ratio of collected insect was showed as 0.57, females more than males. As increased the temperature, developmental period was to be short. Preoviposition was also to be short as 5.0, 4.3, and 3.4 days at 20, 25, 30℃, respectively, and fecundity increased as 69.0, 87.1, and 104.3 at 20, 25, 30℃, respectively. Longevity of male and female at 25℃ was showed the longest with 35.7, and 32.9 days and showed the shortest with 30.1 and 28.1 days at 30℃, respectively. The difference of developmental period in male and female were showed longer in female without relation of temperature. The eggs laid were frequently distributed 3 to 4 ㎝ from soil surface, and showed the behavior laying eggs intensively when early oviposition period.

본 논문에서는 지진으로부터 구조물을 효과적으로 보호하기 위하여 MR 엘라스토머(MRE)를 이용한 새로운 형태의 스마트 기초격리 시스템을 제안하고, 이에 대한 내진성능을 파악하였다. MRE는 자성물질을 포함한 실리콘 혹은 고무로써 자기장에 의해 강성이 변하는 스마트 재료이다. 기초격리 시스템은 토목 및 건축분야에서 구조물의 내진성능 향상을 위해 가장 널리 쓰이는 장치로 지반과 구조물을 격리시켜 구조물에 가해지는 입력 하중을 감소시켜주는 장치이다. 기존 수동형태의 기초격리 장치는 다양한 입력하중에 대한 적응성이 부족하고 기초격리 장치에서의 과도한 변위 등의 단점이 있는 반면, 새로 제안한 시스템은 제어 가능한 강성범위가 넓어 이를 개선할 수 있다. MRE를 이용한 기초격리 장치의 성능을 확인하기 위하여 기초격리 장치를 도입한 단층 및 5층의 건물에 대해 다양한 역사지진 하중을 이용하여 수치해석을 수행하였다. 수치해석 결과, 제안된 시스템은 기존 수동형태의 시스템에 비해 구조물의 응답 및 기초격리장치의 변위를 감소시키는 데 탁월한 효과가 있음을 확인하였다.
Purpose : To provide eye care practitioners with guidelines in selection of lenses based on visual needs of wearer. we measured optical characteristics and analysing distance, intem1ediate. and near zones of each PAL design. Methods : 34 lenses which are selling in the market currently, were ordered through a shop as if for a patient with a prescription of piano distance and a + 2.000 add for right respectively. The total number of tl1e lenses was 34 and they were obtained from the manufacturer directly to get a equatable of lenses. Each lens optics was measured with VM 2000(Visionix Ltd. Israel) three times. Limiting the viewing zone width by 0.500C or + 0.250S. distance. intem1ediate. near viewing zone were analysed respectively by lmm vertical steps. Results : Setting the criterion at addition + 2.000. the maximum unwantcd astigmatism was - 1.95 to -3.560( -2.32±0.37). clistance viewing zone area was 9.17 Lo 91.25 mm2(30.57±17.20 mm2 ) . intermediate vie\ving zone area was 10.52 to 41.21 mm2(19.56±6.88 mm2 ), the highest occurrence of the + 1.750 was apart 10.35 m to 18.16 mm(l3.53±2.02 mm) from fitting cross. and neru· viewing zone area with over + 1.750 was 26.58 to 111.25 mm2(62.31± 18.07 mm2 ). There were significant differences with measurement variables. And the usage ratings were measured on t11e criterion of the distance zone. intermediate zone. and near zone width and their horizontal width. Conclusions : The optical characteristics across the progressive addition lenses tested in this study were showed a variance of wide ranges. The ratings of visual needs of wearer on the distance zone, intermediate corridor and near zone can be used in selection of appropriate lenses to match individual specific needs.
Considering the great potential of iron chelators at inhibiting the proliferation of tumor cells, in order to determine the molecular and biological basis for the effects of iron chelator in oral cancer, we investigated the effects of iron chelator, desferrioxamine (DFO), on the gene profiling analysis of immortalized human oral keratinocytes (IHOK), and oral cancer cells (HN12), using the cDNA microarray. We identified 46 clones cDNA exhibiting more than 2 fold overexpression in DFO treated IHOK and HN12 cells, and 94 cDNA reveal more than 2 fold down-regulated expression. Examination of gene expression that differs between DFO treated vs. control IHOK and HN12 cells apprear to be related to : cell cycle regulator, cell growth and apoptosis, signal transduction and stress. p21 for cell cell cycle factor was upregualted, and cyclin-cdk gene was decreased expression, so we observed cell cycle arrest in DFO treated IHOK and HN12 cells. In tumor growth, we have identified downregulation of hemidesmosomal protein (bullous pemphigoid antigen 1) and epiregulin expression in DFO treated IHOK and oral cancer cells. Signal transducers including mitogen-activated protein kinase-activated protein kinase 5, serine/thereonine kinase 6 were downregulated with DFO treated cells, suggesting the DFO regulates the p38 MAP kianse pathway in immortalized and maignant oral keratincytes. In conclusion, we have demonstrated the high-throughput utility of cDNA array hybridization in parallel to the gene expression analysis to identify genes that are expressed differentially in DFO treated with immortalized and malignant oral keratinocytes. The differentially expressed genes identified here should be informative in DFO-induced anti-cancer effects.
Hoe-amsa temple was renewed by Zen priest Na-ong(1320-76) in the later Goryeo dynasty(918-1392), and he introduced the institution of Zen Buddhism temple of Yuan dynasty(1271-1368) in China. And in 13-14 century, many Zen Buddhism temple were built in east Asia, like China, Japan, Korea and so on. Hoe-amsa temple became to be ruined in the middle years of Joseon dynasty(1392-1910), and the ruin was excavated recently. The purpose of this study is to make a searching examination the history of Hoe-amsa temple by analyzing the historic records and excavation relics, and to clarify the function of Jeongcheong, east Bang-jang and west Bang-jang of Hoe-amsa temple, by comparative analysis with Bang-jang architecture of Zen Buddhism temple of Yuan dynasty. As the result of this study it can be said like follow. Hoe-amsa temple maintained the form made by priest Na-ong in spite of several times of repair in Joseon dynasty, and it was reflected in excavation relics of now. The Jeongcheon of Hoe-amsa temple was the space called Chimdang where the chief priest performed lectures and ceremony, the west Bang-jang was the living space of chief priest, and the east Bang-jang was lodging for honored guest. The architecture composed by Jeongcheong, east Bang-jang and west Bang-jang was the adaptation of institution of Bang-jang architecture of Zen Buddhism temple in Yuan dynasty, on the base of general architecture form of Goryeo dynasty.
