In this study, we assessed biochemical outcomes after robot-assisted radical prostatectomy （RARP）. Between July 2005 and November 2007, one hundred and seventy-six consecutive patients treated by RARP without neoadjuvant treatment were included in this study. All procedures were performed by a single surgeon and the median follow-up period was 60 months （interquartile range （IQR）： 59-69）. The median prostate specific antigen was 7.50 ng ml-1 （IQR： 5.14-11.45） and 39.2% of the patients were classified as intermediate risk and 15.3% were classified as high risk; on final pathological examination, 35.2% of the patients had non-organ confined disease and 37.5% and 14.2% had Gleason scores of 7 and 8-10, respectively. The biochemical recurrence （BCR）-free survival rates at 3 and 5 years were 85.6% and 81.2%, respectively. The 5-year BCR-free survival rates stratified by pathologic Gleason scores were 93.1% in Gleason scores of 6 or less, 74.5% in a Gleason score of 7, and 58.1% in Gleason scores of 8 or greater, respectively （P〈0.001）. When stratified by pathologic stage, the BCR-free survival rates were 89.8% in pT2 patients, 66.2% in pT3a patients, and 39.3% in pT3b patients at 5 years following RARP, respectively （P〈0.001）. Preoperative prostate-specific antigen （PSA）, pathologic stage, postoperative Gleason score and surgical margin status were independently associated with BCR in multivariate analysis. In this study, we report biochemical outcomes after RARP with the longest follow-up periods to date in Asian men. We found that robotic surgery provided satisfactory biochemical outcomes, and that RARP is a safe and effective procedure in terms of oncologic outcomes.

In this study, we reported our experience performing robotic extended lymph node dissection （eLND） in patients with prostate cancer. A total of 147 patients with intermediate and high-risk prostate cancer who underwent robotic eLND from May 2008 to December 2011 were included in this analysis. The dissection template extended to the ureter crossing the iliac vessels. We assessed lymph node yield, lymph node positivity, and perioperative outcomes. Lymph node positivity was also evaluated according to the number of lymph nodes （LNs） removed （〈22 vs 〉22）. The median number of LNs removed was 22 （11-51）, and 97 positive LNs were found in 24 patients （16.3%）. While the obturator fossa was the most common site for LN metastases （42.3%, 41/97）, the internal iliac area was the most common area for a single positive LN packet （20.8%, 5/24）. Eight patients （33.3%, 8/24） had positive LNs at the common iliac area. The incidence of positive LNs did not differ according to the number of LNs removed. Complications associated with eLND occurred in 21 patients （14.3%） and symptomatic lymphocele was found in five patients （3.4%）. In conclusion, robotic eLND can be performed with minimal morbidity. Furthermore, LN yield and the node positive rate achieved using this robotic technique are comparable to those of open series. In addition, the extent of dissection is more important than the absolute number of LNs removed in eLND, and the robotic technique is not a prohibitive factor for performing eLND.

TRISO （Tri-structural iso-tropic）-coated particle fuel is being developed to support the development of a VHTR （very high temperature reactor） in Korea. From August 2013, the first irradiation testing of coated particle fuel was begun to demonstrate and qualify TRISO fuel for use in the VHTR in HANARO （high-flux advanced neutron application reactor） at KAERI （Korea Atomic Energy Research Institute）. This experiment is currently undergoing under an atmosphere of a mixed inert gas without on-line temperature monitoring and control combined with on-line fission product monitoring of the sweep gas. The irradiation device contains two test rods, one contains nine fuel compacts and the other five compacts and eight graphite specimens. Each compact has 263 coated particles. After a peak bum-up of about 4% and a peak fast neutron fluence of about 1.7 × 1021 n/cm2, PIE （post irradiation examination） will be carried out at KAERI＇s irradiated material examination facility. This paper describes the characteristics of coated particle fuels, and the design of the test rod and irradiation device for the coated particle fuels, and discusses the technical results of irradiation testing at HANARO.

Hurst’s memory that roots in early work of the British hydrologist H.E. Hurst remains an open problem in stochastic hydrology. Today, the Hurst analysis is widely used for the hydrological studies for the memory and characteristics of time series and many methodologies have been developed for the analysis. So, there are many different techniques for the estimation of the Hurst exponent (H). However, the techniques can produce different characteristics for the persistence of a time series each other. This study uses several techniques such as adjusted range, rescaled range (RR) analysis, modified rescaled range (MRR) analysis, 1/f power spectral density analysis, Maximum Likelihood Estimation (MLE), detrended fluctuations analysis (DFA), and aggregated variance time (AVT) method for the Hurst exponent estimation. The generated time series from chaos and stochastic systems are analyzed for the comparative study of the techniques. Then, this study discusses the advantages and disadvantages of the techniques and also the limitations of them. We found that DFA is the most appropriate technique for the Hurst exponent estimation for both the short term memory and long term memory. We analyze the SOI (Southern Oscillations Index) and 6 tree-ring series for USA sites by means of DFA and the BDS statistic is used for nonlinearity test of the series. From the results, we found that SOI series is nonlinear time series which has a long term memory of H = 0.92. Contrary to earlier work, all the tree ring series are not random from our analysis. A certain tree ring series show a long term memory of H = 0.97 and nonlinear property. Therefore, we can say that the SOI series has the properties of long memory and nonlinearity and tree ring series could also show long memory and non-linearity.

我国是世界上生产和出口荧光灯最多的国家之一,同时每年也会有数量众多的荧光灯被废弃,这些都伴随着大量的资源消耗以及环境污染。但是关于我国荧光灯的环境影响分析却很少有人研究。对紧凑型荧光灯以及直管型荧光灯进行了全生命周期的环境影响评价,同时又在国家层面对我国荧光灯的生产和出口的环境负荷进行了定量分析。结果表明,对于这两种灯,环境影响最大的阶段是使用阶段,在提供相同的光照条件下,直管型荧光灯的环境影响明显优于紧凑型荧光灯。2011年,我国生产荧光灯会产生1.45亿t CO_2-equivalents和69万t PM2.5-eq,负载了大量的能源资源消耗和污染排放,其中约有一半左右来自于出口的荧光灯。政府需要通过政策措施来引导生产和贸易向环境友好型转变。

A global-local finite element modeling technique is employed in this paper to predict the separation in steel cord-rubber composite materials of radial truck tires. The local model uses a finite element analysis in conjunction with a glob-al-local technique in ABAQUS. A 3-dimensional finite element local model calculates the maximum cyclic shear strain of an interface between steel cord and rubber materials at the carcass ply shoulder region. It is found that the maximum cyclic shear strain is reliable as a result of the analysis of carcass ply separation in radial truck tires. Using the analysis of the local model, a study of the cyclic shear strain is performed in the shoulder region and used to deter-mine the carcass ply separation. The effect of the change of carcass ply design on the separation in steel cord-rubber composite materials of radial truck tires is discussed.
