분산 환경에 존재하는 다양한 이기종의 계산 자원은 가상화 기술을 통해 통합된 고성능 컴퓨팅 환경을 구축한다. 최근, 사용자 수준의 향상으로 인해 복잡한 응용 작업의 처리에 대한 요구가 증가하고 있으며, 이는 고성능 컴퓨팅에 대한 수요로 이어지고 있다. 사용자가 요구하는 각각의 작업에는 데이터가 포함되어 있고, 각각의 데이터는 고유의 특성을 가지고 있으므로, 작업의 분류와 처리는 데이터의 특성이 고려되어야 한다. 본 논문에서는 분산 환경에서 계산 자원의 효율 증대를 위한 데이터 특성 기반의 작업 분류방법(JCDT : Job Classifying method based on Data Traits for Increased Efficiency of Computational Resources in Distributed Environment) 을 제안한다. 제안하는 JCDT 는 사용자가 요구하는 작업이 지닌 데이터의 특성을 기반으로 작업을 분류하여, 계산 자원의 효율 증대와 작업 처리속도를 향상시킬 수 있을 것으로 기대한다. Various computational resources in distributed environment are to build a high-performance computing environments through virtualization technology. Recently, there is a growing need for a complicated process due to the improvement of the user-level application, which has led to demand for high-performance computing. The requested job from users is composed of data. And because of each data has own characteristics, the classifier may consider the features of data. In this paper, we propose Job Classifying method based on Data Traits for Increased Efficiency of Computational Resources in Distributed Environment (JCDT). JCDT classifies the job by data traits of the users' request, is expected to improve the job processing time and increase the processing speed of the calculation resources.

Six new uridine-conjugates of penicillin G and peptides have been prepared and evaluated against mouse lymphoblastoma L5178Y cells, Staphylococcus aureus(IAM 3610) and Escherichia coli (ATCC 10536). These include 5`-amino-5`-deoxyuridine-penicillin G(14), 5`-amino-5`-deoxyuridine-cyclo(Phe-Asp)(15-I), 5`-amino-5`-deoxyuridine-cyclo (Phe-Glu)(15-II), 5-iodo-5`-amino-2`,3`-0-isopropylidene uridine-penicillin G(16), 5-iodo-5`-amino-5`-deoxyuridine-penicillin G(17), and 5`-deoxyuridine-penicillin G(19). IC_(50) values were 18.0 ㎍/㎖, 6.5 ㎍/㎖, 6.5 ㎍/㎖, 13.5 ㎍/㎖, 6.5 ㎍/㎖ and 9.0 ㎍/㎖, respectively. MIC values of (15-I) and (17) were 6.25 ㎍/㎖. These preliminary results support the thesis that the uridine conjugates of this type may require a naturally occuring moiety for improved efficacy.

When it comes to current growth trend for the printing process in Asia printing market, offset printing, gravure printing and screen printing are reduced respectively -4%, -19%, -55%. In judging from the fact, the change in the printing production system from mass production on small amount to small production on mass amount is the biggest issue. For this reason, digital printing shows the significant growth. According to the increase of the growth 78% for electro photography way and 67% for ink-jet, it's not enough to catch up with digital printing which is increasing as time goes by to equip with hardware like as digital press. There's been necessary to install the BOD(Book on Demand) system which is the advanced and regular publication edit solution based on web-to-print model in the prepress, and it has made the BOD system be considered in relation to maximization of efficiency and production. Therefore, this research tries to step forward from the POD concept, which is refired to "Print along with the ordered quantities, the ordered appropriate time and the demanded place", so that it could expand the range of the printing/publishing environment using the BOD system, the order-made publication based on automatically operating template. And it tried to make the relation to digital web press on ink-jet method which is adequate to "mass production on small amount" with such advanced concept. This research also aims to use actively BOD solution model to promote the productivity of labor, and then to produce the printings across all related industries, which means to manufacture maximally the products on the shortest time at minimum place through PC equipments.

This is to report the result of the clinical treatment of One Proteinuria patient who has been hospitalized from January 2003 to August 2003 in Kwangdong Oriental Medicine Hospital. Proteinuria is an important sign of renal disease. It is very useful to estimate the patterns of proteinuria in differential diagnosis of renal disease. One patient have been diagnosed as the determination of the protein creatinine ratio when properly interpreted can replace the total urine collection for 24 hours in the clinical question of proteinuria when hospitalized. Therefore, We met One patient having Proteinuria and acquired good result by treatment with Taeyeumin Jowesungcheongtang plus jejo and bupeong for 4months. This paper describe the process and contents about the patient was cured.

Embryonic stem cells (ESC) are thought to be a powerful tool for cell replacement in degenerated or damaged cells, including those in central nerve system because ESC are known to be pluripotent and capable of differentiating into various cell types found in adult body. In general, ESCs are differentiated into specific cell lineages through the formation of embryoid body (EB). We demonstrated the direct differentiation of mouse embryonic stem cells (mESC) into neuronal cells in culture from mESC aggregation, which were cultured in suspension for only 48 hrs. To process the differentiation of ES aggregates, they were attached onto poly-L-ornithin and fibronectin coated plates (stage I). Then media was changed to early-differentiated media supplement N2 in DMEM/F12 (stage II), during aggregates were expanded fully. After 7 days, we changed media for late differentiation media supplement N2 and B27 in DMEM/F12 for 7 days (stage III). After total 15 days, differentiated cells were observed by immunnocytochemistry with neuronal lineage markers such as neuronal nuclei (NeuN), microtubule-associated proteins-2 (MAP2), and tubulin 3. In addition, RT-PCR analysis showed the gene expression of nestin, OTX2, MAP2. Nestin and OTX2 gene were detected in the neuronal precursor cells and then decreased in differentiated neuronal cells. However, expression of MAP2 gene expression was detected in late differentiated (stage III) cells. Taken together, newly developed neuronal differentiation system without EB formation may be efficient method to drive rapid differentiation mESC into neuronal cells.

이 연구는 서울지역 초등발명교실에서 이루어지고 있는 발명교육프로그램 분석을 통해 발명교실 강사의 교육프로그램에 대한 동의수준을 알아보고 교육프로그램 요소별 중요도에 대해 어떠한 인식을 가지고 있는가를 알아보기 위해 수행하였다. 이를 위해 서울 소재 6개 발명교실에서 이루어지고 있는 교육프로그램들을 분석하였으며, 문헌고찰(이용환, 2005; 특허청, 2008)을 통해 발명교실 교육프로그램들을 몇 가지 요소로 범주화하여 설문지를 개발하였다. 발명교실에서 운영하고 있는 프로그램에 대한발명교실 강사들의 동의수준을 알아보기 위해 교육프로그램에 대해 1점(전혀 중요하지 않음)부터 5점(매우중요)까지의 점수를 부여하였고, 중요도에 대한 순위는 3개 항목만을 선택하여 순서대로 기입하도록 하였다. 초등발명교실 강사로 활동하고 있는 현직교사 32명을 대상으로 설문조사를 실시하였으며, 4개의 연구변인(성별, 연령, 발명교실 강의경력, 발명관련 연수경험)에 따라 여러 가지 교육프로그램에 대해 발명교실 강사들이 인식하고 있는 동의수준과 중요도에 따른 순위를 조사하였다. 이 연구의 결과를 요약하면 다음과 같다. 첫째, 서울소재 발명교실에서 운영되고 있는 발명교실 교육프로그램은 크게 30가지로 정리할 수 있었다. 둘째, 서울 소재 발명교실에서 운영되고 있는 발명교실 교육내용에 관련하여 발명교실 강사들의 동의 수준은 평균 3.80으로서 대체로 긍정적으로 생각하고 있는 것으로 나타났다. 가장 높은 동의수준을 보인 내용은 아이디어 창출을 위한 다양한 착상기법교육프로그램이었으며, 투석기 제작은 가장 낮은 동의수준을 보였다. 셋째, 초등발명교실 강사들은 발명교실 교육내용 중 아이디어 창출을 위한 착상기법 교육프로그램을 가장 중요하게 생각하고 있었으며, 그 다음이 기존 제품에 대한 비판적 사고와 개선방안, 발명 원리와 기법의 이해 및 체험 순이었다. 넷째, 초등발명교실 강사들이 설문지 내용에는 진술되지 않은 발명교실 교육내용 중 꼭 다루어져야 한다는 내용으로는 발명과 예술에 대한 학습, 생활 속 발명품 찾기, 광고와 창의성이라는 의견이 나왔다. 이 연구 결과는 추후 발명교실 운영계획안을 수립할 때에 교육프로그램에 대한 정보를 제공할 것으로 기대된다. The purpose of this study is to look into the agreement level and significance degree of invention education perceived by teachers of invention classes in elementary schools. SPSS 12.0 for Windows was employed to statistically analyze 32 of 36 completed questionnaires response on a 5-point scale to various statements regarding contents of invention education. The findings of this study were as follows. First, There were thirty contents in elementary school invention classes. Second, teachers in charge of elementary school invention classes positively viewed with an average of 3.80/5 regarding the contents of invention education presented. The content of the highest agreement was "various methodologies to create new ideas." and the content of the lowest agreement was "catapult production." Third, the teachers in charge of invention classes at elementary school attached the greatest importance to "various methodologies to create new ideas." among several contents in the curriculum, followed by "critique and innovation of existing products" and "understanding and experiencing principles/methods of invention." Fourth, the teachers suggested new ideas for a better curriculum, such as "studies on invention and arts", "inventions in our daily lives", "advertisement and creativity."
