반도체 공정에서 인 메모리 데이터 그리드를 이용한 고속의 빅데이터 처리 시스템 구현

박종범,이방원,김성중 한국ITS학회 2016 한국ITS학회논문지 Vol.15 No.5

최근 하드웨어와 소프웨어의 발전으로 데이터의 처리 용량과 처리 속도도 급속하게 증가하고 있다. 이로 인한 데이터 사용량은 기하급수적으로 증가하고 있으며, 이미 컴퓨터가 처리해야하는 자료는 초당 5천 트랜잭션을 넘었다. 이처럼 빅데이터가 중요한 이유는 실시간 때문이며, 이는 어떠한 상황에서도 모든 데이터를 분석하여 정확한 데이터를 적시에 얻을 수 있기 때문이다. 또한, 빅데이터를 활용한 스마트 공장을 만들면 개발 및 생산비용, 품질관리 비용 감소효과가 있을 것으로 예상하고 많은 연구가 수행되고 있다. 본 논문에서는 많은 데이터들이 발생하는 반도체 공정에서 고속의 빅데이터 처리를 위한 인-메모리 데이터 그리드를 이용한 시스템을 구현하였으며, 실험을 통해 향상된 성능을 입증하였다. 구현한 시스템은 반도체 뿐 만 아니라 빅데이터를 사용하는 모든 부분에서 응용 가능 할 것으로 판단된다. Data processing capacity and speed are rapidly increasing due to the development of hardware and software in recent time. As a result, data usage is geometrically increasing and the amount of data which computers have to process has already exceeded five-thousand transaction per second. That is, the importance of Big Data is due to its ‘real-time’ and this makes it possible to analyze all the data in order to obtain accurate data at right time under any circumstances. Moreover, there are many researches about this as construction of smart factory with the application of Big Data is expected to have reduction in development, production, and quality management cost. In this paper, system using In-Memory Data Grid for high speed processing is implemnted in semiconductor process which numerous data occur and improved performance is proven with experiments. Implemented system is expected to be possible to apply on not only the semiconductor but also any fields using Big Data and further researches will be made for possible application on other fields.

뿌리 스트레스를 유발하는 agar농도에 따른 Kalanchoe pinnata의 체세포 배 형성 변화

박종범,김동균,김진석 한국식물생명공학회 2017 JOURNAL OF PLANT BIOTECHNOLOGY Vol.44 No.3

Development of modern agricultural machinery and accompanying agricultural development cause soil compaction and reduce growth by stressing roots. Kalanchoe pinnata was used to investigate the impact of stress on rooting and changes in plant growth and reproduction. K. pinnata forms somatic embryos capable of asexual reproduction at the edge of leaves. Impact of root pressurization of K. pinnata on somatic embryogenesis and organ differentiation according to external stress factors was investigated by using a high concentration of agar and this phenomenon was studied histologically. Agar concentration in culture media ranged from 0.5%-1.5% to induce a compression effect on roots. The stem and leaf of K. pinnata were subjected to a microtechnique process to study changes in tissue. In vivo, K. pinnata produced 2nd and 3rd plantlets at edges of leaves from lack of water and excessive lighting conditions. In in vitro culture studies, the lower the concentration of agar, the higher the population and the higher the biomass, but plantlet did not occur in leaf bends. Conversely, as concentration of agar increased, increase in the number of individuals was low. Plantlet development occurred only in agar 1.5% medium. The difference in agar concentration was a stressor in the root of K. pinnata, and thus the pattern of asexual reproduction changed from the division method in root to a plantlet generation in leaf. This suggests root pressurization may act as stress and change in the plant reproduction pattern.

중소기업 구성원의 문화지능과 개인 주도성이 창의적 자기효능감에 미치는 영향: 호혜성과 신뢰의 매개효과

박종범,서영욱 한국유통경영학회 2022 유통경영학회지 Vol.25 No.5

Purpose: How can creative ideas be realized by increasing the creative self-efficacy of small and medium-sized enterprise members? The question is for research purposes. After identifying the importance and interrelationship of the variables most needed f or SMEs, It is intended to present a desirable development direction that can contribute to the development of organizations and members of SMEs. Research design, data, and methodology: A survey was conducted on members working at small and medium-sized enterprises across the country and received 200 questionnaires. Based on the final 186-part questionnaire data faithfully completed, research data analysis was conducted on the effect of cultural intelligence and Personal initiative on creative self-efficacy through reciprocity and trust using statistical analysis programs SPSS 23.0 and SmartPLS 3.0 Results: First, metacognitive cultural intelligence had a positive (+) effect on creative self-efficacy through reciprocity, but a negative (-) effect on creative self-efficacy through trust was confirmed. Second, motivational cultural intelligence confirmed a positive (+) effect on creative self-efficacy through reciprocity and a positive (+) effect on creative self-efficacy through trust. Third, Personal initiative also confirmed a positive (+) effect on creative self-efficacy through reciprocity, and a positive (+) effect on creative self-efficacy through trust. Implications: In the current situation where research on cultural intelligence targeting foreigners with cultural differences is concentrated, it is of great significance that research on cultural intelligence was conducted on members of domestic SMEs.

Overexpression of Stress-Related Genes, BrERF4 and AtMYB44, in Arabidopsis thaliana Alters Cell Expansion but Not Cell Proliferation During Leaf Growth

박종범,Pamella Marie Sendon,So Hyun Kwon,서학수,박순기,김정회,송종태 한국식물학회 2012 Journal of Plant Biology Vol.55 No.5

We have previously shown that overexpression of BrERF4 (Brassica rapa ETHYLENE-RESPONSIVE FACTOR4)increases salt and drought tolerance in Arabidopsis plants,and also retarded organ growth. In the present study, we investigated in detail the leaf growth retardation phenotype at the cellular level. Results showed that BrERF4-overexpressing Arabidopsis plants developed small leaves by reducing their cell size but not the cell number. Detailed kinematic analysis revealed that changes in cell size appeared from the very early stages of leaf development, directly affecting the size of leaf organs. RT-PCR analysis showed that expression of expansin genes was reduced in the overexpressors, whereas expression of the cell cycle gene, CYCB1;1, was not altered at all. In addition, overexpression of AtMYB44, another stress-related transcription factor gene, reduced leaf growth,which also resulted from reduction in cell size but not in cell number. These results suggest that overexpression of those transcription factors negatively affects cell expansion during leaf growth without altering cell number. We discuss about the advantages that the BrERF4- or AtMYB44-induced cell expansion retardation confers on plants under natural environmental adversity.

Small Interfering RNA‒Mediated Suppression of Fas Modulate Apoptosis and Proliferation in Rat Intervertebral Disc Cells

박종범,박찬주 대한척추외과학회 2017 Asian Spine Journal Vol.11 No.5

Study Design: In vitro cell culture model. Purpose: To investigate the effect of small interfering RNA (siRNA) on Fas expression, apoptosis, and proliferation in serum-deprived rat disc cells. Overview of Literature: Synthetic siRNA can trigger an RNA interference (RNAi) response in mammalian cells and precipitate the inhibition of specific gene expression. However, the potential utility of siRNA technology in downregulation of specific genes associated with disc cell apoptosis remains unclear. Methods: Rat disc cells were isolated and cultured in the presence of either 10% fetal bovine serum (FBS) (normal control) or 0% FBS (serum deprivation to induce apoptosis) for 48 hours. Fas expression, apoptosis, and proliferation were determined. Additionally, siRNA oligonucleotides against Fas (Fas siRNA) were transfected into rat disc cells to suppress Fas expression. Changes in Fas expression were assessed by reverse transcription-polymerase chain reaction and semiquantitatively analyzed using densitometry. The effect of Fas siRNA on apoptosis and proliferation of rat disc cells were also determined. Negative siRNA and transfection agent alone (Mock) were used as controls. Results: Serum deprivation increased apoptosis by 40.3% (p <0.001), decreased proliferation by 45.3% (p <0.001), and upregulated Fas expression. Additionally, Fas siRNA suppressed Fas expression in serum-deprived cultures, with 68.5% reduction at the mRNA level compared to the control cultures (p <0.001). Finally, Fas siRNA‒mediated suppression of Fas expression significantly inhibited apoptosis by 9.3% and increased proliferation by 21% in serum-deprived cultures (p <0.05 for both). Conclusions: The observed dual positive effect of Fas siRNA might be a powerful therapeutic approach for disc degeneration by suppression of harmful gene expression.
