The purpose of this study is a comparison of forward planning(FP) and inverse planning(IP) of a radiosurgery procedure. 10 patients of acoustic schwannoma MR image were used for treatment plan. FP-1,2 and IP were established under the same condition. FP and IP were compared by number of shot, conformity index(CI), paddic conformity index(PCI), gradiant index(GI) and treatment time. On average the treatment plan produced by IP tool provided an improved or similar CI, PCI, GI and reduced treatment time as compared to the FP (CI;FP-1:0.85, FP-2:0.86, IP:0.94, PCI;FP-1:0.79, FP-2:0.81, IP:0.78, GI;FP-1:2.94, FP-2:2.94, IP:3.01). The inverse planning system provides a clinically useful plan while reducing the planning time and treatment time.

In this paper, we propose a new mobility management scheme, called i-FP(intelligent Fast PMIPv6). Our proposed i-FP scheme is addressed for solving the existing local mobility management problems from legacy frameworks. To move MN(Mobile Node) to other networks in one domain, i-FP employs three network entities which are extended from PMIPv6(Proxy Mobile IPv6), LMA(Local Mobility Anchor), MAG(Mobile Access Gateway) and MN. In i-FP, the three network entities can reduce the handover delay time of MNs. Also, i-FP uses an IP header swapping mechanism to avoid the traffic overhead and improve the throughput of network. To evaluate the performance of i-FP, we analyze our i-FP, HMIPv6(Hierarchical Mobile IPv6) and PMIPv6 which are legacy protocols of local mobility management in terms of various parameters. Finally, our i-FP scheme shows good performance(reduction of routing hops 10.2%, signaling costs 58.5% and handover delay 16.3%) than other network schemes for the total cost.

Purified preparations of flacherie virus capsid protein were fractionated by SDS-polyacrylamide gel electrophoresis, and amino acid composition was determined by amino acid analyzer. Three polypeptide components, FP I, FP II and FP III were detected, and the molecular weights of these components were 37,500, 30,500 and 26,500 respectively. The FP III was major poly-peptide comprised about 68.4% of the total virus capsid protein. Seventeen amino acids were detected by an amino acid analyzer from hydrolyzate of the virus capsid protein and the pattern of amino acid composition was similar to those of several other insect viruses.

In this paper, we consider a fractional robust optimization problem (FP) and give necessary optimality theorems for (FP). Establishing a nonfractional optimization problem (NFP) equivalent to (FP), we formulate a Mond-Weir type dual problem for (FP) and prove duality theorems for (FP).

Softwares, especially like machine learning applications, affect human's life style tremendously. Accordingly, the importance of the cost model for softwares increases rapidly. As cost models, LOC(Line of Code) and M/M(Man-Month) estimates the quantitative aspects of the software. Differently from them, FP(Function Point) focuses on estimating the functional characteristics of software. FP is efficient in the aspect that it estimates qualitative characteristics. FP, however, has a limit for evaluating machine learning softwares because FP does not evaluate the critical factors of machine learning software. In this paper, we propose an extended function point(ExFP) that extends FP to adopt hyper parameter and the complexity of its optimization as the characteristics of the machine learning applications. In the evaluation reflecting the characteristics of machine learning applications. we reveals the effectiveness of the proposed ExFP.

Cardiac chambers serve as mechanosensory systems during the haemodynamic or mechanical disturbances. To examine a possible role of fluid pressure (FP) in the regulatien of atrial $Ca^{2+}$ signaling we investigated the effect of FP on L-type $Ca^{2+}$ current $(I_{Ca})$ in rat ventricular myocytes using whole-cell patch-clamp technique. FP $(\sim40cm\;H_2O)$ was applied to whole area of single myocytes with electronically controlled micro-jet system. FP suppressed the magnitude of peak $I_{Ca}$ by $\cong25\%$ at 0 mV without changing voltage dependence of the current-voltage relationship. FP significantly accelerated slow component in inactivation of $I_{Ca}$, but not its fast component. Analysis of steady-state inactivation curve revealed a reduction of the number of $Ca^{2+}$ channels available for activity in the presence of FP. Dialysis of myocytes with high concentration of immobile $Ca^{2+}$ buffer partially attenuated the FP-induced suppression of $I_{Ca}$. In addition, the intracellular $Ca^{2+}$ buttering abolished the FP-induced acceleration of slow component in $I_{Ca}$ inactivation. These results indicate that FP sup-presses $Ca^{2+}$ currents, in part, by increasing cytosolic $Ca^{2+}$ concentration.

EU는 세계에서 가장 큰 규모의 국제 공동연구개발 프로그램으로서 FP(Framework Programm(이하 FP)을 1050년대 이후로 추진하고 있다. 매년 6년 단위로 실행되고 있으며 현재 2011년에서 제 7차 2007년에서 2013년까지 프로그램이 추진되고 있다. 이는 향후 2014년부터 2020년까지 진행되는 제 8차 FP의 토대가 된다. 현재 우리나라 정부는 FP참여를 통한 EU권과의 국제기술협력을 위해서 적극적으로 지원정책을 펴고 있다. 이러한 정책은 특히 현재 이루어지고 있는 제 7차 FP에 대한 체계적인 분석이 필요하다. 이에 본 논문에서는 지금까지 이루어지지 않는 EU의 제 7차 FP의 참여현황을 구체적으로 EU회원국과 비 회원국들을 나누어서 살펴보는데 연구의 목적을 두도록 한다.

The FP-tree(Frequency Pattern Tree) mining association rules algorithm was proposed to improve mining performance by reducing DB scan overhead dramatically, and it is recognized that the performance of it is better than that of any other algorithms based on different approaches. But the FP-tree algorithm needs a few more memory because it has to store all transactions including frequent itemsets of the DB. This paper implements a FP-tree algorithm on a general purpose UNK system and compares it with the DHP(Direct Hashing and Pruning) algorithm which uses hash tree and direct hash table from the point of memory usage and execution time. The results show surprisingly that the FP-tree algorithm is poor than the DHP algorithm in some cases even if the system memory is sufficient for the FP-tree. The characteristics of the test data are as follows. The site of DB is look, the number of total items is $1K{\sim}7K$, avenrage length of transactions is $5{\sim}10$, avergage size of maximal frequent itemsets is $2{\sim}12$(these are typical attributes of data for large-scale convenience stores).

The culture media from Fomitopsis pinicola were extracted by methanol and examined growth inhibition against Helicobacter pylori. The culture media from 8 days fermentation of F. pinicola showed maximum inhibition activity on H. pylori in 0.25 mg as MIC value. The highest activity against H. pylori by MHCS agar diffusion medium by Fp-P1 in 22.7 mm ID among 3 peaks from methanol fraction of 8 days culture media of Fomitopsis pinicola which purified by ion-exchange chromatography. The Fp-P1 from DEAE-Sephadex A-25 have been analysed by TLC as Fp-T1, Fp-T2 and Fp-T3 by ninhydrin staining. Fp-T3 (Rf value : 0.67) was higher activity against H. pylori in 14.4 mm ID. Fp-T3 was identified as single band by HPLC and TLC. It was assumed to aminosugar by BioLC analysis and TLC staining.

배경: 채혈 후 제제 경과시간에 따른 동결혈장의 혈액응고인자의 활성도와 이에 영향을 미치는 요인을 분석하여, 혈액응고인자제제의 원료혈장의 사용범위를 확장 가능한지 확인하고자 동결혈장의 채혈시간과 응고인자 특성을 측정하였다. 방법: ALT 부적격 혈장을 채혈 후 동결시간의 특성에 따라 4단계로 구분하였고, 6종류의 혈액 응고인자 활성도와 혈액형을 검사하였고, SAS 9.2 프로그램을 사용하여 통계처리 하였다. 결과: 혈액제제간 FVIII 활성도를 분석한 결과 PL-A>FFP>FP(8-24)${\approx}$FP(24-72) 순으로 유의하게 낮아졌고 혈액형에 따라서는 AB형이 제일 높고, O형이 제일 낮았다. 대한적십자사의 원료혈장에 대한 FVIII 활성 품질기준을 적용할 경우 PL-A, FFP와 FP24는 각각 85.0%와 82.5%로 적합하였다. 캐나다 퀘백 주처럼 FP24의 FVIII 활성이 0.52 IU/mL 이상을 적용할 경우 PL-A, FFP와 FP24는 각각 95.0%, 96.3%, 82.6%로 적합하였다. 또한 FP(8-24)의 A형과 AB형, FP(24-72)의 경우 AB형이 각각 82.1%, 83.3%, 100%로 적합하였다. 결론: 혈액응고인자제제용 원료혈장의 범위는 외국의 기준에 비추어 채혈 후 24시간 내에 동결된 혈장(FP24)으로 확대 사용이 가능하다. 이를 위해서는 채혈 후 동결시간과 혈액응고인자에 대한 품질기준을 유럽약전 또는 WHO 가이드라인과 비교하여 완화하는 것이 필요하다.
