수비무관 평균자책점 (FIP)는 운과 수비력을 제외한 투수가 가진 고유의 능력만을 평가하는 지표로 야구팬들에게 매우 지지도가 높다. 미국 메이저리그 야구에서는 홈런, 볼넷, 삼진, 사구만을 이용하여 계산하는 FIP의 계수를 13, 3, -2로 사용한다. 그러나 메이저리그 야구의 득점가치를 바탕으로 정해진 계수들을 한국 프로야구에 접목시키면 팀이나 선수들의 평가가 적절하지 않을 수 있다. 본 연구에서는 한국프로야구에 적합한 FIP의 계수를 제안하고 평균자책점 (ERA)과의 연관성을 살펴본다. 그 결과 제안된 방법 kFIP는 한국프로야구에서 기존의 FIP에 비해 통계적으로 매우 유의하게 평균자책점에 대한 연관성을 높일 수 있었다.

캡사이신 채널로 알려진 바닐로이드 수용체 TRPV1 (캡사이신채널, Transient Receptor Potential Vanilloid 1)은 통증발현에서 중요한 역할을 하는 것으로 알려져 있다. 하지만 TRPV1의 활성조절에 관여하는 단백질에 대하여는 알려진 바가 많지 않다. 최근 rat TRPV1과 직접적으로 결합하는 단백질을 탐색하여 mouse Rab11-FIP3 (rab11-family interaction protein 3)가 rat TRPV1과 직접적으로 결합한다는 것이 보고되었다. Rab11은 여러 가지의 세포내 이동에 관여하는 것으로 보고되었다. 그러므로 Rab11-FIP3과의 결합을 통해 TRPV1의 세포막으로의 이동에 관여할 것으로 추측할 수 있다. 본 연구에서는 전에 보고된 연구가 mouse와 rat 이라는 다른 종의 단백질끼리의 결합이기 때문에 같은 종에서의 상호작용을 확인하고 Rab11-FIP3의 TRPV1의 세포막으로의 이동에서의 역할을 알아보고자 현재까지 동정되지 않은 rat의 Rab11-FIP3의 유전자를 GenBank 서열을 바탕으로 rat 뇌의 RNA 로부터 cDNA 를 클로닝하여 유전자를 분리하고 TRPV1 과의 관계를 세포생물학적으로 알아보았다. 연구결과 rat의 Rab11-FIP3는 489개의 아미노산 서열을 가지고 있으며 human과는 80%, mouse와는 90% 이상 아미노산 서열의 상동성을 보였다. 조직별 분포는 심장, 뇌, 간, 콩팥, 정소에서 발현되고 있는 것을 northern blot assay와 western blot assay 로 확인하였다. rat 의 뇌조직에서 TRPV1 과 Rab11-FIP3 단백질이 결합하여 colocalize 하는 것을 면역화학방법으로 확인하였다. 이 결합은 같은 family 의 TRPV2 와는 결합하지 않는 특이적 결합이므로 Rab11-FIP3 가 TRPV1 과 상호작용하여 세포막으로의 이동에 관여할 것이라는 것을 시사한다.

Not much is known about the membrane trafficking of TRPV1, a key player in pain transduction. Rab11-FIP3, which plays a role in various intracellular transportation pathways, has been reported to interact with TRPV1. In this study, in order to examine the role of Rab11-FIP3 in the membrane trafficking of TRPV1, Rab11-FIP3 expression in dorsal root ganglion (DRG) was inhibited using a siRNA technique. Transportation of TRPV1 to membranes was found to decrease when Rab11-FIP3 expression was inhibited, consistent with the results obtained with TRPV1-transfected HEK cells. Taken together, these results indicate that Rab11-FIP3 plays a role in the membrane trafficking of TRPV1.

Objective : To investigate the effect between Fructus Immaturus Ponciri (FIP, the immature fruit of Poncirus trifoliata) and Fructus Ponciri (FP, the ripe fruit of Poncirus trifoliata) on mast cell-mediated immediate-type allergic reactions. Methods : We performed anaphylactic reaction, histamine release, cAMP, $TNF-{\alpha}$, IgE. Results : The aqueous extract of FIP dose-dependently inhibited systemic and local allergic reaction was induced by compound 48/80 or anti-dinitrophenyl (DNP) IgE in a murine model. FIP also significantly inhibited mast cell-dependent ear swelling response induced by topical application of compound 48/80. When mice were orally pretreated with FIP, the plasma histamine levels were reduced in a dose-dependent manner. FIP dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) was activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when FIP was added, increased compared with that of a normal or control. In addition, FIP had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-a ($TNF-{\alpha}$) production from the RPMCs and IgE produced by lipopolysaccharide-stimulated murine whole spleen cells or U266B1 as human IgE-bearing B cells. However, FP showed the lower inhibition rate than those of FIP in above all allergic reactions. Conclusion : These data have important implications for our understanding of the clinical effects of FIP and FP on allergic diseases, and FIP is more effective than FP on the allergic reaction.

This paper describes an experimental investigation on the influence of concrete strength on tension stiffening behavior. Total 6 direct tension specimens were tested with variation of concrete strengths such as 260, 620, and 820kgf/$\textrm{cm}^2$. These test results were compared with tension stiffening models of CEB-FIP Model Code. It was appeared that, as concrete strength was increasing, CEB-FIP models estimated much more tension stiffening than these test results. As the result, it would be said that the influence of concrete strength on tension stiffening was not properly taken account for in CEB-FIP model.

Pancreatin is a enzyme mixture breaking down carbohydrates, proteins and lipids. Most pancreatin used in Korea is imported from foreign countries. However, guideline of each country for pancreatin produced from each country is different. Therefore, guideline for pancreatin imported from several countries, such as Europe, Japan and America, it is standardized to control its quality. Assay of enzyme activity for pancreatin in KP is similar to tat in JP, but it is significantly different from those in FP ad in USP. We measured pancreatin digestive activities of 17 commercial products. Activity assay of digestive enzymes, starch- and lipid-digestive enzymes, for pancreatin by KP method (including JP) was difficult compared to those by FIP ad USP methods. Particularly, activity assays of starch- and lipid-digestive enzymes by KP method were mistakable, ad varied in diluted samples than those by FIP. However, activity assay of protein-digestive enzyme by KP method was similar to that by FIP. Starch-digestive enzyme activities of 17 commercial pancreatins by KP method were lower 0.079-fold compared to those by FIP method. Their protein-digestive enzyme activities by KP method were higher 75.7-fold than those by FIP method. Their lipid-digestive enzyme activities by KP method were lower 0.234-fold compared to those by FIP method.

A five-month-old, male Domestic Korean shorthair was referred to our hospital with a history of lethargy, anorexia, and globoid cardiac silhouette on thoracic radiography. Physical examination showed dehydration and anemia was revealed on blood analysis. On thoracic radiography and echocardiography, the patient showed pericardial effusion and ultrasound-guided pericardiocentesis was performed. A Rivalta test of the pericardial effusion showed a positive result. As the patient had recurrent pericardial effusion, pericardiectomy was performed. He was tentatively diagnosed with wet form feline infectious peritonitis (FIP) and treated with Polyprenyl immunostimulant (PI). Neurological signs were eventually seen and he was euthanized. Histopathologic changes with markedly expanded neutrophils, lymphocytes, plasma cells, and macrophages with fibrous connective tissue and collagenous fibers were detected. Immunohistochemistry for FIP antigen was performed and results showed FIPV-positive multifocal aggregates of cells. Pericardial effusion is an atypical condition in cats with FIP, but can be presented. This case report describes FIP with pericardial effusion in a cat, in which definitive diagnosis of FIP was done using biopsy via pericardiectomy.

Bioavailability of ipriflavone (3-phenyl-7-isopropoxy-4H-I-benzopyran-4-one, IP), an antiosteoporotic drug with poor water-solubility, was studied for various types of pharmaceutical preparation in SD rats. The IP preparation types included (1) intact IP, (2) freezer milled IP (FIP), (3) freezer milled IP physically mixed with freezer milled poly-N-vinylpyrrolidone (PVP) (FIP+FPVP) and (4) spray-dried IP with PVP (SIP). Upon oral administration, SIP showed significantly higher absorption and elimination half-lives and the lag time $(t_{lag})$ than those of FIP+FPVP (approximately 2-fold). These results may be due to a sustained releasing effect of IP in the gastrointestinal tract by spray-drying with PVP. The $C_{max}$ of SIP was about 2 and 10 times higher than those of FIP+FPVP and FIP, respectively. The AUC of SIP was about 6 times higher than that of FIP+FPVP and 60 times that of FIP. Scanning electron microscopy (SEM) showed that SIP consisted of the finest particle size and minimal aggregation than other IP preparations. It is concluded that the IP formula prepared by the spray-drying method with PVP is the most effective approach to the improvement of bioavailability of IP.

최근들어 구조물공사에 적용되는 콘크리트가 고강도화 되어가는 추세로서 크리프와 같은 콘크리트의 역학적 거동에 대한 기존 설계예측식에 대한 전면적인 검토가 필요한 시점이다. 이에, 본 연구에서는 현행 국내 철근콘크리트 구조설계기준상의 크리프계수 예측 모델식에 대한 강도대별 적용 타당성을 검토하기 위한 일환으로 기존의 제안 모델식인 ACI 209R, CEB-FIP MC90 및 EC2 모델식을 검토 하였으며, 실험결과와 비교검토를 수행하였다. 모델식 검토결과, CEB-FIP MC90 모델의 개선식인 EC2 모델이 고강도대의 콘크리트에 대한 크리프계수를 보다 현실적으로 예측함을 확인할 수 있었으며, 실험결과와도 상대적으로 좋은 상관성을 보임을 확인하였다.

Networking for manufacturing is gaining importance as a nerve system of computer-integrated manufacturing(CIM). Among the various network types, the most inexpensive type called fieldbus is specifically aimed to interconnect simple devices such as sensors and actuators. For this purpose, there are several choices of the protocol such as Profibus, FIP, Foundation Fieldbus, and IEC/ISA fieldbus. This paper presents the simulation results of Profibus and FIP. Both protocols has been simulated in order to evaluate the performance such as transmission delay and throughput under different protocol parameter setting and traffic conditions.
