  • 새로운 비즈니스 환경 변화에 가장 빠르게 대응하는 것이 중요한 IT 환경에서 빠른 서비스의 생성과 컴포넌트의 재활용성이 중요해지고 있다. 한편, 기존 Legacy 시스템의 한계를 극복한 WOA(Web Oriented Architecture)가 부각되고 있지만 Web 기반 시스템의 경우 Legacy 시스템 측정에 알맞게 구축된 비용산정에 어려움을 겪고 있으며, 잘못된 비용 산정의 결과로 인하여 다수의 프로젝트가 실패할 위험을 안고 있다. 따라서 본 논문은 현재 국내 소프트웨어 개발 규모 산정을 위한 국제 표준인 FP(Function Point)를 통한 규모 산정 방식을 제안한다. 본 논문은 기존 FP방식이 가질수 있는 문제점을 제시하고, 기존 산정방식의 문제점을 개선한 연계 기능을 포함한 FP 산출 방법의 제안을 통해 WOA 도메인의 특징을 반영한 FP의 산출이 가능하다. 이를 통하여 WOA 기반 시스템의 정확한 예산 측정이 가능하며, 프로젝트의 실패를 감소할 수 있다.

  • Austenite formation and Low temperatures mechanical properties of HSLA steel of different starting structures have been studied by intercritical annealing(IA). The different starting structures are: ferrite+pearlite(FP1), martensite(M1), cold worked ferrite+pearlite(FP2) and cold worked martensite(M2). In most cases tensile strength and elongation was increased by decreasing the testing temperatures regardless of the IA time. Tensile strength of the cold worked starting structures was higher than that of the non-cold worked starting structures. However not any noticeable difference in elongation was found between two cases. Low temperatures impact properties were affected by the starting structures. Charpy V-notch impact transition temperatures of the M-starting structures were around $-40^{\circ}C$, and those of the FP starting structures were around $-10^{\circ}C$. Impact energy was lower in the cold worked specimens than in the non-cold worked specimens at the same starting structures. DP structure obtained from the M-starting structure has shown superior low temperatures mechanical properties than the DP structure obtained from the FP-starting structure.

  • This study is aimed to inspect how the different sensitivities in Behavioral activation system (BAS) and Behavioral inhibition system (BIS) modulate on the properties of physiological responses stimulated by positive or negative affective sound. We measured the electroencephalogram (EEG) of 32 students, consisted of four groups depending on the BAS and BIS sensitivities, during listening to meditation music or noise. The EEG was recorded at Fp1 and Fp2 sites. After listening to music or noise, subjects reported the affect induced by the sound. For EEG, the power in the alpha band at Fp2, especially in the alpha-2 band (9.0-11.0 Hz) increased during the subjects listening to music, while the power at Fp1 increased during noise. During listening to meditation music, there is a tendency that the left-sided activation in prefrontal cortex (PFC) is positively correlated with the difference of BAS(Z)-BIS(Z). During listening to noise, there is a tendency that the right-sided activation in PFC is dominant in case any of the sensitivity of BAS or BIS is high. From these results we suggest that the physiological responses of different individuals in BAS and BIS react differently under the same emotionally provocative challenge.

  • A cDNA Fragment encoding iron storage protrin generated by polymerase chain reaction(PCR) using highly conserved regions of ferritin related genes were used to sereen a red pepper cDNA library. cDNA clone was designated as Fp1. Fp1 clone contatines a 5' nontranslated region of 51dp containing stop conds. Down stream from 5' UTP. an open reading frame of 750bp was observed. followed by a 3' UTR of 272bp. The deduces amino acid sequence of red pepper protein(Fp1) showed 84%, 48% and 36% identity with soybean(SolC). human(HuL H) and horse spleen(HoS-L) ferritin mRNA accumulation in response to iron. Ferritin mRNA accumulation was transient and particularly abundant in leaves. reaching a maxmum at 12h. The level of ferritin mRNA in roots was affected to a lesser extent than in leaves.

  • Recently, use of light-weight panel is increasing in building. Styrofoam sandwich panel is inexpensive and it is excellent in insulation ability and constructability. But styrofoam of panel inside is low ignition point. Consequently, when panel is fired, it is occur in poisonous gas. On the other hand, light-weight foamed concrete is excellent in insulation ability, fire resistance due to inner pore. Properties of light-weight concrete is influenced by foaming agent type. Accordingly, this study investigate in insulation property of according to foaming agent type in order to using light-weight foamed concrete instead of styrofoam. As a results, Non-heating zone temperature of light-weight foamed concrete of using AP, FP are lower than light-weight foamed concrete of using AES. Light-weight foamed concrete of using AES, FP are satisfied with fire performance of two hours at foam ratio 50, 100. Light-weight foamed concrete of using AP is satisfied with fire performance of two hours at AP ratio 0.1, 0.15. Insulation property is better closed pore by made AP, FP than open pore by made AES.

  • Maximum cellulase production was sought by comparing the activities of the cellulases produced by different Trichoderma reesei strains and Aspergillus niger. Trichoderma reesei Rut-C30 showed higher cellulase activity than other Trichoderma reesei stains and Aspergillus niger that was isolated from soil. By optimizing the cultivation conditions during shake flask culture, higher cellulase production could be achieved. The FP(filter paper) activity of 3.7U/ml and CMCase (Carboxymethylcellulase) activity of 60U/ml were obtained from shake flask culture. When it was grown in 2.5L fermentor, where pH and DO levels are controlled, the enzyme activities were 133.35U/ml (CMCase) and 11.67U/ml(FP), respectively. Ammonium sulfate precipitation method was used to recover enzymes from fermentation broth. The dried cellulase powder showed 3074.9U/g of CMCase activity and 166.7U/g of FP activity with 83.5% CMCase recovery.

  • 본 연구에서는 감성 평가 시스템 가장 적합한 파라미터를 찾기 위하여 3가지 뇌파 파라미터를 이용하여 감정 분류 실험을 하였다. 뇌파 파라미터는 선형예측기계수(linear predictor coefficients)와 FFT 스펙트럼 및 AR 스펙트럼의 밴드별 상호상관계수(cross-correlation coefficients)를 이용하였으며, 감정은 relaxation, joy, sadness, irritation으로 설정하였다. 뇌파 데이터는 대학의 연극동아리 학생 4명을 대상으로 수집하였으며, 전극 위치는 Fp1, Fp2, F3, F4, T3, T4, P3, P4, O1, O2를 사용하였다. 수집된 뇌파 데이터는 전처리를 거친 후 특징 파라미터를 추출하고 패턴 분류기로 사용된 신경회로망(neural network)에 입력하여 감정 분류를 하였다. 감정 분류실험 결과 선형예측기계수를 이용하는 것이 다른 2가지 보다 좋은 성능을 나타내었다.

  • Gen-2 Q-알고리즘에서는 태그의 수가 적은 상태에서 초기 $Q_{fp}$ 값을 크게 하면 빈 슬롯이 많이 발생하고, 태그의 수가 많은 상태에서 초기 $Q_{fp}$ 값을 적게 하면 충돌이 많이 발생한다. 또한 적절하지 못한 가중치를 선택할 경우 빈 슬롯 또는 충돌 슬롯이 많이 발생할 수 있다. 이로 인하여 질의 라운드 동안 최적의 프레임 크기에 수렴하는 속도가 늦어지므로 성능이 저하되는 문제점이 있다. 본 논문에서는 태그 수를 추정하여 현재의 슬롯-카운트 크기에 따라 가중치를 결정하는 기법을 제안하고, 이에 대한 성능을 분석한다.

  • In order to reduce risks from the Steam Generator Tube Rupture (SGTR) accident and to meet safety targets, various measures have been analyzed to minimize the amount of fission product (FP) release. In this paper, we propose an introduction of a Containment Filtered Venting System (CFVS) connected to the steam generator secondary side, which can reduce the amount of FP release while minimizing adverse effects identified in the previous studies. In order to compare the effect of new equipment with the existing strategy, accident simulations using MELCOR were performed. As a result of simulations, it is confirmed that CFVS operation lowers FP release into the environment, and the release fractions are lower (minimum 0.6% of the initial inventory for Cs) than that of the strategy which intends to depressurize the primary system directly (minimum 15.2% for Cs). The sensitivity analyses identify that refill of the CFVS vessel is a dominant contributor reducing the amount of FP released. As the new strategy has the possibility of hydrogen combustion and detonation in CFVS, the installation of an igniter inside the CFVS vessel may be considered in reducing such hydrogen risk.
