Operational efficiencies and costs of an arm roll forwarder: A case study at Nasu in Tochigi Prefecture, Japan

Journal of Forestry Research 2013年第3期24卷 577-583页

We investigated a developed arm roll forwarder at Nasu in Tochigi Prefecture, Japan. An arm roll forwarder can only load a steel container that has been fully loaded with logs beforehand, and can later unload such a container. Such a forwarder can shorten the loading and untoading times and improve operational efficiency. We examined two operation systems with an arm roll forwarder and a forwarder. In the first system the loading was done with a grapple-loader. In the second system the loading was done with a processor. The loading times of an arm roll forwarder were significantly tess than those of a forwarder. Because the optimal cycle times （excluding the waiting times for an arm roll for- warder） were significantly reduced, the costs of using an arm roll for- warder are lower, although the loading capacity was small and the hourly operation cost was high. The maximum operational efficiencies varied depending on forwarding distances. The second operation system with an arm roll forwarder exhibited the best operational efficiency within a 1,580-m forwarding distance, and beyond that distance it exhibited the highest operational efficiency when a forwarder was used. Similarly, the cost of operation of the system with an arm roll forwarder was the lowest within a 1,130-m forwarding distance, and beyond that distance the cost was the lowest when using the forwarder. Therefore, the arm roll for- warder is effective within a certain forwarding distance.

Experimental evaluation of an on-demand multipath routing protocol for video transmission in mobile ad hoc networks

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2006年第Z1期7卷 145-150页

作者： TANIYAMA Kenta MORII Takeshi KOIZUMI Shinya NOGUCHI kazuhiro KOTANI Yukihiro KATTO Jiro Graduate School of Science and Engineering Waseda University Tokyo 169-8555Japan

We propose an on-demand multipath routing algorithm in a mobile ad hoc network for video transmission and evaluate its real world performance in video streaming application. There have been a number of multipath routing protocols extended from AODV which is a well-known single path routing protocol. Multipath routing protocols indicate good performance in the reduction of route discovery latency and unnecessary routing packets in simulations. We show that the route establishment using source route lists provided by us (Hu and Johnson, 2002) can reduce the route discovery latency, select stable routes automatically, and work well for live video streaming without limitation of the hop count based approaches. We evaluate this proposed method compared with the original AODV by using eight laptop PCs and demonstrate live streaming experiments.

Long-term efficacy of endoscopic coagulation for different types of gastric vascular ectasia

引用

World Journal of Gastroenterology 2013年第18期19卷 2799-2805页

作者： Yukinori imai Yoshie Mizuno Kiyoko Yoshino kazuhiro Watanabe Kayoko Sugawara Daisuke Motoya Masashi Oka Satoshi Mochida Department of Gastroenterology and Hepatology Faculty of Medicine Saitama Medical University Saitama 350-0495 Japan

AIM: To examine the long-term therapeutic efficacies of endoscopic cauterization for gastric vascular ectasia, according to the type of lesion. METHODS: Thirty-eight patients with hemorrhagic gastric vascular ectasia (VE) were treated by endoscopic cauterization: 13 by heater probe coagulationand 25 by argon plasma coagulation. Depending on the number of lesions, 14 and 24 patients were classified into localized VE (≤ 10; LVE) and extensive VE (> 10; EVE), respectively. The patients were followedup by repeated endoscopic examinations after the therapy, and the incidences of VE recurrence and rebleeding from the lesions were evaluated. RESULTS: Although the VE lesions disappeared initially in all the patients after the therapy, the recurrence of VE developed in 25 patients (66%) over a mid-term observation period of 32 mo, and re-bleeding occurred in 15 patients (39%). The recurrence of VE was found in all patients with EVE, with re-bleeding occurring in 14 patients (58%). In contrast, only 1 patient (7%) with LVE showed recurrence of the lesions and complicating hemorrhage. Both the cumulative recurrence-free rates and cumulative re-bleeding-free rates were significantly lower in the EVE group than in the LVE group (P < 0.001 and P < 0.001, respectively). Moreover, the cumulative re-bleeding-free rate in the EVE group was 47.6% at 1 year and 25.4% at 2 years in patients with chronic renal failure, which were significantly lower than the rates in the patients without chronic renal failure (83.3% and 74.1%, respectively) (P < 0.05). CONCLUSION: The recurrence of VE and re-bleeding from the lesions was more frequent in the patients with EVE, especially in those with complicating renal failure.

Thrombocytopenia after liver transplantation:should we care?

引用

World Journal of Gastroenterology 2018年第13期24卷 1386-1397页

作者： kazuhiro Takahashi Shunji Nagai Mohamed Safwan Chen Liang Nobuhiro Ohkohchi Department of Surgery Division of Gastroenterological and Hepatobiliary Surgery and Organ Transplantation University of TsukubaTsukubaIbaraki 3058575Japan Transplant and Hepatobiliary Surgery Henry Ford HospitalDetroitMl 48202United States

Transient thrombocytopenia is a common phenomenon after liver transplantation. After liver transplantation(LT), platelet count decreases and reaches a nadir on postoperative days 3-5, with an average reduction in platelet counts of 60%; platelet count recovers to preoperative levels approximately two weeks after LT. The putative mechanisms include haemodilution, decreased platelet production, increased sequestration, medications, infections, thrombosis, or combination of these processes. However, the precise mechanisms remain unclear. The role of platelets in liver transplantation has been highlighted in recent years, and particular attention has been given to their effects beyond hemostasis and thrombosis. Previous studies have demonstrated that perioperative thrombocytopenia causes poor graft regeneration, increases the incidence of postoperative morbidity, and deteriorates the graft and decreases patient survival in both the short and long term after liver transplantation. Platelet therapies to increase perioperative platelet counts, such as thrombopoietin, thrombopoietin receptor agonist, platelet transfusion, splenectomy, and intravenous immunoglobulin treatment might have a potential for improving graft survival, however clinical trials are lacking. Further studies are warranted to detect direct evidence on whether thrombocytopenia is the cause or result of poor-graft function and postoperative complications, and to determine who needs platelet therapies in order to prevent postoperative complications and thus improve post-transplant outcomes.

Cryoablation-Induced Anti-Cancer Immune Reaction—Immune Reaction Induced By Cryoablation

引用

Journal of Cancer Therapy 2011年第2期2卷 135-139页

作者： Shinji Osada Hisashi imai Yoshiyuki Sasaki Itaru Yasufuku Ryuichi Asai Yoshihisa Tokumaru Takuji Sakuratani kazuhiro Yoshida Surgical Oncology Gifu University School of Medicine Yanagido Gifu City JAPAN.

Among the ablation procedures used against advanced liver cancer, thermal ablation therapy is widely applied, and the safety and efficacy of this technique have been well characterized. In contrast, the principle of cryosurgery is not only to control local recurrence, but also to stimulate the immune system into initiating an anti-tumor response. In recent years, we have developed a treatment method for patients with advanced liver tumors. From these experiences, repeated treatment was demonstrated to induce anti-cancer immune reaction-related factors. In the present review, mechanisms for anti-tumor immune reaction will be argued with introducing a novel strategy of a cryoablation.

The advantages of radical distribution control and independent dual frequency on etch/ash

引用

半导体技术 2004年第8期29卷 41-46页

作者： Tanaka Hideaki Kubota kazuhiro Shin Okamoto Tokyo Electron Ltd. Tokyo Electron Ltd.Tokyo Electron Ltd.

The transition to 65 nm beyond and 300 mm wafers posed many challenges on etch depth and critical dimension (CD) uniformity within wafer. In this paper, we introduce a radical distribution con- trol (RDC) system for an excellent uniformity control. Etch depth and CD uniformity within wafer are well controlled by adding RDC function to SCCMTM. For increasing productivity, an all-in-one process, that is, etch/ash at the same chamber continuously is proposed here. By utilizing the advantage of inde- pendent dual frequency, a bias-controlled two-step ash “hybrid ash” is combined in the all-in-one process. Hybrid ash uses bias control and low pres- sure to minimize liner loss and the damage of low-k materials, which is targeting 65nm and beyond.
