Banknote Recognition Based on Continuous Change in Strictness of Examination

Kazuo Nishimura 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

This paper proposes a model of human recognition that simulates a human"s continuous change in observation from rough overall check to fine detailed check. It has been applied to banknote recognition. Banknote classification for twenty eight samples has demonstrated that the proposed method enables to identify not only the kind of a banknote but also its degree of weariness.

Empirical Evaluation of Object-Oriented Programming Effectiveness in Different Types of Program

Kazuo Nishimura 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

This paper discusses effectiveness of object-oriented programming by applying it to five different types of program; that is, load flow computation, inference engine, semantic network, minimum distance path problem, and back propagation learning algorithm for three layer neural network. The results will give some clues to readers to determine whether they should employ object-oriented programming or not when they need to develop a program.

Current status of robotic surgery in Japan

Kazuo Nishimura 대한비뇨의학회 2015 Investigative and Clinical Urology Vol.56 No.3

The da Vinci S surgical system (Intuitive Surgical) was approved as a medical device in 2009 by the Japanese Ministry of Health,Labour and Welfare. Robotic surgery has since been used in gastrointestinal, thoracic, gynecological, and urological surgeries. InApril 2012, robotic-assisted laparoscopic radical prostatectomy (RALP) was first approved for insurance coverage. Since then, RALPhas been increasingly used, with more than 3,000 RALP procedures performed by March 2013. By July 2014, 183 institutions inJapan had installed the da Vinci surgical system. Other types of robotic surgeries are not widespread because they are not coveredby public health insurance. Clinical trials using robotic partial nephrectomy and robotic gastrectomy for renal and gastric cancers,respectively, have recently begun as advanced medical treatments to evaluate health insurance coverage. These procedures must beevaluated for efficacy and safety before being covered by public health insurance. Other types of robotic surgery are being evaluatedin clinical studies. There are several challenges in robotic surgery, including accreditation, training, efficacy, and cost. The largest issueis the cost-benefit balance. In this review, the current situation and a prospective view of robotic surgery in Japan are discussed.

For application of NATM, the self-supporting until installation of the supporting system must be satisfied. However, the face of a tunnel are always unsupported and therefore it is fairly vulnerable to tunnel collapses. Face blots are well known and widely used to prevent the deformation of the tunnel face and its circumference, which are installed horizontally toward the tunnel axis generally. To maximize the supporting effect of face bolts, this study has analysed the effective design patterns of face bolts by changing their installation angles. As the conclusion, it has been found that the axial displacement of the face increases slightly by installing the outermost bolts upward from the axis but surface settlement at 2.5D behind the face decreases up to 18%. 터널굴착시 NATM이 적용되기 위해서는 「굴착 후 지보공의 시공이 완료되기 전까지 막장이 자립하고 있을 것」을 전제조건으로 하고 있지만 터널막장은 항상 무보강의 상태가 계속되고 있고, 붕괴사고가 집중되고 있는 가장 취약한 부분이라고 할 수 있다. 이에 대한 대책공법 중 페이스볼트는 주로 막장전방을 향하여 수평으로 설치해 막장을 보강하는 공법으로 널리 알려져 있다. 본 연구는 페이스볼트의 설치효과를 극대화시키기 위해 일률적인 수평설치의 패턴을 변경해 보다 효율적인 설계패턴에 대해 검토하였다. 그 결과, 최외곽부의 볼트들을 터널 축방향의 윗방향으로 배치함으로써 막장 수평변위는 다소 증가하지만, 막장후방 2.5D의 천단침하는 약 18% 줄일 수 있는 것이 확인되었다.

실내실험 및 수치해석을 이용한 막장볼트의 최적 타설 개수에 관한 연구

최근 국외에서는 터널막장의 안정을 위해 막장볼트의 시공실적이 급증하고 있고 관련된 많은 실험, 계측등의 자료가 발표되고 있지만 현장마다 지반조건, 볼트 종류가 틀리기 때문에 설계 단계에서 최적의 타설개수를 결정하는 것은 매우 어렵다. 본 연구에서는 우선 현장조사를 통하여 사용되는 막장볼트의 종류, 개수 등을 분석하였다. 이결과 막장볼트는 다른 공법과 병용하여 사용되는 경우가 많기 때문에 지반조건과의 상관관계는 보이지 않았다. 또한 현장조사를 바탕으로 한 실내시험 및 수치해석을 통해 터널 막장이 볼트로 보강되었을 경우 지반 및 볼트의 거동을 분석하였으며 특히 타설개수에 초점을 맞추었다. 실험결과 막장볼트의 개수가 증가할수록 지표면침하 및 막장수평변위는 지수함수 형태의 변위감소 분포를 보이고 있는 것으로 나타났다. The use of face bolt method has been increasing abroad recently. Hence, many tests and measurements are being conducted and reported. Also, it is well known that determination of the installation number of face bolts in the design stage is very difficult due to difference of the ground condition and the type of a bolt to be used. First of all, the type, the number, etc. of bolts used in various tunnel construction sites, investigated, are analyzed. The relationship between bolt and ground condition could not be found because bolts have been used with the other support methods in many cases. In the laboratory test and numerical analysis based on the site investigation, the behavior of ground and pipes installed on the tunnel face to support has been examined. Especially, the installed number is focused on. According to the result of tests, the surface settlement and the axial displacement of the face decrease exponentially as the number of installed bolts increases.

Favorable Outcome in Elderly Asian Patients with Metastatic Renal Cell Carcinoma Treated with Everolimus: The Osaka Urologic Oncology Group

Inamoto, Teruo,Azuma, Haruhito,Nonomura, Norio,Nakatani, Tatsuya,Matsuda, Tadashi,Nozawa, Masahiro,Ueda, Takeshi,Kinoshita, Hidefumi,Nishimura, Kazuo,Kanayama, Hiro-Omi,Miki, Tsuneharu,Tomita, Yoshihi Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Background: In clinical trials with no upper age limit, the proportion of older patients is usually small, probably reflecting the more conservative approach adopted by clinicians when treating the elderly. An exploratory analysis of elderly patients in the RECORD-1 Trial showed that patients ${\geq}$ 65 y.o. had superior median PFS than overall RECORD-1 population (5.4 months and 4.9 months, respectively). We investigated the efficacy, relative benefit and safety of Everolimus (EVE) as sequential therapy after failure of VEGFr-TKI therapy for older patients with metastatic renal cell cancer (mRCC), in daily practice. Materials and Methods: 172 consecutive IRB approved patients with mRCC (median age 65, M:F 135/37, 78% clear cell) who received salvage EVE at 39 tertiary institutions between October 2009 and August 2011 were included in this analysis. Some 31% had progressed on sunitinib, 22% on sorafenib, 1% on axitinib, 41% on sequential therapy, and 5% had received other therapy. Patients with brain metastases were not included and 95% of the patients had a ECOG (Eastern Cooperative Oncology Group) performance status (PS) of 0 or 1. Previous radiotherapy was an exclusion criterion, but prior chemotherapy was permitted. Adequate organ function and hematologic parameters were mandatory. EVE administration was approved by the institutional review board at each participating institution and signed informed consent was obtained from all patients. Results: Median time of the whole cohort to last follow-up was 3.5 months (range 0.4-15.2 months). Forty four percent were continuing to take EVE at last followup. There were 86 (50%) patients ${\geq}$ 65 y.o. and 86 (50%) <65 y.o. The percentage of patients who showed PR/SD was higher in the older group than in the younger one (5.9%/61.2% vs 1.2%/46.5%, respectively). Median survival of older patients was also significantly longer (3.5 +/- 0.31 vs 3.1 +/- 0.34, hazard ratio=0.45, CI; 0.255-0.802). Analysis using Cox regression model adjusted for gender, PS, number of metastases, site of metastases, histology, smoking history and age detected an association between age and PFS (p=0.011). The frequency of adverse events in elderly patients treated with EVE was no greater than that in younger patients, although such toxicity may have had a greater impact on their quality of life. Conclusions: Older patients should not generally be excluded from accepted therapies (mTOR inhibitors after failure of VEGFr-TKI therapy) for mRCC.
