The highly loaded turbine blades are able to reduce both the number of blades and the stages of turbojet-engines. In this study, PIV(Particle Image Velocimetry) method is used for the measurements of the secondary flow in ultra-highly loaded turbine blade cascades. The results obtained by the PIV method clearly show the complicated behavior of the secondary flow in the cascade. The horseshoe vortex and the passage vortex are observed inside the cascade. Moreover, the wake generated by the accumulation of the low energy fluid by the passage vortex near the suction side and that discharged toward downstream of the trailing edge has been recognized.

Japanese convenience store chain Seven-Eleven Japan (hereinafter 'SEJ') has been profitable for 30 years by constantly anticipating changing trends regardless of the severe business environment. In this paper, the knowledge creation process and its supportive systems in SEJ to examine how information system can support knowledge creation are described. Using case study method, the knowledge creation theory is applied to SEJ, and the results show that facilitating 'dialogue' and reinforcing 'creative routine' might be the most important functions of information system to support knowledge creation.

Endoscopic treatment for bile duct stones is low-invasive and currently considered as the first choice of the treatment. For the treatment of bile duct stones, papillary treatment is necessary, and the treatments used at the time are broadly classified into two types; endoscopic papillary balloon dilatation where bile duct closing part is dilated with a balloon and endoscopic sphincterotomy(EST) where bile duct closing part is incised. Both procedures have advantages and disadvantages. Golden standard is EST, however, there are patients with difficulty for EST, thus we must select the procedure based on understanding of the characteristics of the procedure, and patient backgrounds.

Cytosolic chaperonin CCT (also known as TRiC) is a hetero-oligomeric cage-like molecular chaperone that assists in protein folding by ATPase cycle-dependent conformational changes. However, role of the nucleo-tide binding and hydrolysis in CCT-assisted protein folding is still poorly understood. We purified CCT by using ATP-Sepharose and other columns, and found that CCT possesses ability to hydrolyze GTP, with an activity level very similar to the ATPase activity. CCT was more resistant to proteinase K treatment in the presence of GTP or ATP. These results suggest that the GTPase activity of CCT may play a role in chaperone-assisted protein folding.

AIM: To examine whether it is possible to prevent the occurrence of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis in patients experiencing difficulties with selective biliary duct cannulation by pancreatic duct stenting using a looptipped ***: Procedure success rate, frequency of unintended insertion of the guidewire into side branches of the pancreatic duct, and incidence of procedural accidents were examined using a loop-tipped guidewire(Group A, 20 patients), and a conventional straighttype guidewire(Group B, 20 patients).RESULTS: The success rate of the procedure was 100% in both groups. Unintended insertion of the guidewire into a side branch of the pancreatic duct occurred 0.056 ± 0.23(0-1) times in Group A and 2.3 ±1.84(0-5) times in Group B; thus, unintended insertion of the guidewire into a side branch of the pancreatic duct was seen significantly less frequently in Group A. There were no procedural accidents in Group A, whereas pancreatitis occurred in one Group B patient; however, the difference between the two groups was not statistically significant. The serum amylase level after ERCP was 257.15 ± 136.4(88-628) IU/L in Group A, and 552.05 ± 534.57(101-2389) IU/L in Group B, showing a significantly lower value in Group A. Hyperamylasemia was found in two patients(10%) in Group A, and nine(45%) in Group B, showing a significantly lower value in Group ***: The results suggest that in patients who experience difficulties with biliary cannulation, the use of a loop-tipped guidewire for pancreatic duct stenting may assist with the prevention of post-ERCP pancreatitis, and thereby to a reduction of the risk of post-ERCP pancreatitis or hyperamylasemia.

稻麦轮作农田是氨挥发、氧化亚氮(N_(2)O)排放和硝酸盐淋溶的重要来源。虽然减少氮肥用量能降低氮环境负效应,但会带来作物减产的风险。施用铁粉可刺激水稻田土壤铁还原细菌生长,增强其固氮活性。研究设置传统施氮量100%N、传统施氮量80%N、传统施氮量80%N+Fe、传统施氮量60%N、传统施氮量60%N+Fe、不施氮0%N、不施氮0%N+Fe共7个处理,通过田间原位试验研究氮肥减施和配施铁粉对作物产量、氨挥发、N_(2)O排放和硝酸盐淋溶的影响。结果表明,2021年麦季80%N+Fe处理的小麦产量较80%N处理提高了9.70%,水稻产量与传统施氮量处理相当,减氮20%配施铁粉具有稳产、增产的效果。水稻田氨挥发随着氮肥用量减少而明显降低(P<0.05);80%N+Fe处理与传统施氮量相比则进一步降低了累积氨挥发量与氨挥发强度(P<0.05),降幅分别为50.99%和47.41%。2021年麦季80%N+Fe处理的N_(2)O排放量较80%N处理显著降低78.16%(P<0.05),稻季与传统施氮量相比降低18.27%。同时,80%N+Fe处理也降低了土壤深层渗滤液硝态氮淋溶。因此,在传统氮肥用量基础上减氮20%配施Fe能起到作物稳产的效果,这可能是因为施加Fe增强了水稻田铁还原细菌固氮活性。农田氨挥发、N_(2)O排放和硝态氮淋溶减少主要是氮肥减施所致,相应的土壤微生物机理值得进一步探索。

Preoperative biliary drainage(PBD) was developed to improve obstructive jaundice, which affects a number of organs and physiological mechanisms in patients waiting for surgery. However, its role in patients who will undergo pancreaticoduodenectomy for biliary obstruction remains controversial. This article aims to review the current status of the use of preoperative drainage for distal biliary obstruction. Relevant articles published from 1980 to 2015 were identified by searching MEDLINE and Pub Med using the keywords "PBD", "pancreaticoduodenectomy", and "obstructive jaundice". Additional papers were identified by a manual search of the references from key articles. Current studies have demonstrated that PBD should not be routinely performed because of the postoperative complications. PBD should only be considered in carefully selected patients, particularly in cases where surgery had to be delayed. PBD may be needed in patients with severe jaundice, concomitant cholangitis, or severe malnutrition. The optimal method of biliary drainage has yet to be confirmed. PBD should be performed by endoscopic routes rather than by percutaneous routes to avoid metastatic tumor seeding. Endoscopic stenting or nasobiliary drainage can be selected. Although more expensive, the use of metallic stents remains a viable option to achieve effective drainage without cholangitis and reintervention.
