The evidence for the existence of a common pathway for health issues in men is presented in this review. Several epidemiological studies have shown that conditions like cardiovascular diseases (CVD), metabolic syndrome, diabetes, lower urinary tract symptom (LUTS), erectile dysfunction (ED), prostate cancer, hypogonadism, depression and suicide can be associated as risk factors for each other. Thus, the risk of CVD is significantly increased in men with metabolic syndrome, ED, hypogonadism, prostate cancer and/or LUTS. In addition, the above mentioned conditions are more prevalent in atherosclerotic patients. In addition, growing evidence indicates that low androgen levels can cause metabolic syndrome. In addition, obesity, dyslipidaemia and diabetes can further reduce androgen levels potentiating their adverse effect. Low testosterone levels are also associated with a higher incidence of aggressive prostate cancer on biopsy and on definitive pathology, and lower probability of abiraterone response in the metastatic setting. Several recent studies point towards diffuse endothelial dysfunction and dysregulated pro-inflammatory state as the biological link between all these disorders. Our current hypothesis is that oxidative stress caused by these dysfunctions explains the pathogenesis of each of these conditions.

For better estimation of elastic property of concrete composites, the effect of Interfacial Transition Zone (ITZ) has been found to be significant. Numerical concrete composites models have been introduced using Finite Element Method (FEM), where ITZ is modeled as a thin shell surrounding aggregate. Therefore, difficulties arise from the mesh generation. In this study, a numerical concrete composites model in 3D based on FEM and random unit cell method is proposed to calculate elastic modulus of concrete composites with ITZ. The validity of the model has been verified by comparing the calculated elastic modulus with those obtained from other analytical and numerical models.

지난 2008년 미국 대통령 오바마가 대선 후보시절, 온라인 상의 개인정보와 프라이버시 보호에 대한 강화의지를 피력한 기사를 볼 수 있었다. 마케팅 천국이라고 불리는 미국에서 온라인 상에서 수집되는 개인정보가 어떻게 보호될 것인지 그리고 그에 따른 강력한 미 정부규제는 어떻게 진행될 것인지 궁금해 지는 대목이었다. 그런 의미에서 오바마에게 연방정부 차원의 CPO를 임명할 것을 요구했던 Future Of Privacy Forum의 회장인 Jules Polonetsky와 이메일 인터뷰를 진행했다. 그는 American Online, AIM, Netscape 등 AOL 자회사 소비자 보호 및 리스크 관리 이슈 담당자를 거쳐, TRUSTe, IAPP, Direct Marketing Associationd의 프라이버시 위원회 등에서 프라이버시 및 소비자 보호 관련 임원을 맡고 있다.

Based on in-situ monitoring data produced by National Institute of Meteorological Sciences, we evaluated the performance of Joint UK Land Environment Simulator (JULES) on the surface energy balance for rice-paddy and cropland in Korea with the operational ancillary data used for Unified Model (UM) Local Data Assimilation and Prediction System (LDAPS) (CTL) and the high-resolution ancillary data from external sources (EXP). For these experiments, we employed the one-year (March 2015~February 2016) observations of eddy-covariance fluxes and soil moisture contents from a double-cropping rice-paddy in BoSeong and a cropland in AnDong. On the rice-paddy site the model performed better in the CTL experiment except for the sensible heat flux, and the latent heat flux was underestimated in both of experiments which can be inferred that the model represents flood-irrigated surface poorly. On the cropland site the model performance of the EXP experiment was worse than that of CTL experiment related to unrealistic surface type fractions. The pattern of the modeled soil moisture was similar to the observation but more variable in time. Our results shed a light on that 1) the improvement of land scheme for the flood-irrigated rice-paddy and 2) the construction of appropriate high-resolution ancillary data should be considered in the future research.

The $H_{\infty}$ approach, adopted in this paper, is based on loop shaping using a normalized coprime factor combined with a field-oriented control to control induction motor. We develop two loops. The first one, the inner loop, controls the stator current by $H{\infty}$ controller in order to obtain good performance. The second loop, the outer one, guarantees stability and tracking performance of speed and rotor flux using a proportional integral controller. When the rotor flux cannot be measured, we introduce a flux observer to estimate the rotor flux. Simulation and experimental results are presented to validate the effectiveness and the good performance of this control technique.

한반도 선태식물 연구 역사와 문헌을 정리하였다. 한반도 선태식물의 최초 채집은 20세기 초 프랑스 신부 Urban Faurie에 의해 수행되었는데, 이 표본들 중 선류는 Jules Cardot, 태류는 Franz Stephani에 의해 주로 연구되었다. 한반도 선태식물에 대한 일본인의 연구를 연대순으로 기술하였다. 또한 홍원식과 최두문의 남한 선태식물 목록과 식물상에 관한 연구업적을 정리하였으며, 최근 북한의 선태식물 연구 문헌을 소개하였다.

A robust control intended for a nonholonomic mobile robot is considered to guarantee good tracking a desired trajectory. The main drawbacks of the mobile robot model are the existence of nonholonomic constraints, uncertain system parameters and un-modeled dynamics. in order to overcome these drawbacks, we propose a robust control based on Lyapunov theory associated with sliding-mode control, this solution shows good robustness with respect to parameter variations, measurement errors, noise and guarantees position and velocity tracking. The global asymptotic stability of the overall system is proven theoretically. The simulation results largely confirm the effectiveness of the proposed control.
