The survival benefit of younger age is nullified when patients are stratified by gene expression group. Thus, the main cause of the age effect in GBMs is the more frequent occurrence of PN GBMs in younger patients relative to older patients.

This paper presents a new PWM method for the three-level GTO inverters based on the space voltage vectors. With the proposed PWM method, we can minimize the harmonic components of the output voltage by avoiding the minimum pulse width limitation problem of the GTO thyristors and keeping the voltage balancing of the DC-link capacitors. The principle of the proposed PWM method and the voltage vector output sequences are described in detail. Computer simulation and experimental results verify that

This paper proposes a novel SVPWM (space vector pulse width modulation) strategy for a multi-level voltage source inverter. This strategy is easily implemented as SPWM (sinusoidal pulse width modulation) and has the same DC-link voltage utilization as the general SVPWM scheme. The method to keep the voltage balance of the DC-link is also proposed by the analysis of DC-link voltage fluctuations. The usefulness of the proposed SVPWM is verified through simulation studies.

While natural and ecological integration in the Mekong River basinwere well-sustained for thousands of years, for now being segmented by6 national borders, the cost and benefit of the Mekong River developmentwas divided with asymmetry structure. There have been seriouscontroversies and conflicts among Mekong River riparian states withregard to various kind of the Mekong development, especially on theconstruction of hydropower dam in the Mekong mainstream. Recentlythe issues were even more compli

In recent Laos has attempted to change the fundamentally through the openness and economic reform policy. However, in spite of active and aggressive effort of government, Lao still couldn't get the position out of the Least Developed Countries due to few population and rare natural resource. In these poor economic situation, Official Development Assistance (ODA) which flows into Laos has play an important role and has great influence in Lao country. This article is to review the current situati

The innervated distally based FDMA flap with a wide pedicle could be a good alternative method for repair of soft tissue defects of the great toe.

In the semiquantitative SPECT/CT examinations of patients with TFCC tears, those with concomitant UIS had a higher SUVmax than those without UIS. Semiquantitative SPECT/CT can be helpful in confirming concomitant UIS in patients with TFCC tears.

We evaluated the effect of 13.56 MHz modulated electro-hyperthermia (mEHT) boost in neoadjuvant treatment for cT3-4- or cN-positive rectal cancer. Sixty patients who completed the mEHT feasibility trial (ClinicalTrials.gov Identifier: NCT02546596) were analyzed. Whole pelvis radiotherapy of 40 Gy, mEHT boost twice a week during radiotherapy, and surgical resection 6-8 weeks following radiotherapy were performed. The median age was 59. The median follow-up period was 58 (6-85) months. Total/near

This study showed that when 2 triceps screws were used, both groups were stable during light exercise, but posterior-plating was stronger than double-plating.

Since mid of 1990's Vietnamese food had been advanced in Korea, the franchises and branches of the Vietnam food restaurant remarkably has grown in numbers. It was estimated that the number of Vietnamese food franchise was not less than 30's and the market size of food industry would be around 200 million dollars in Korea. While the interests and study on the globalization of Korean food had been recently increasing, the Southeast Asian food, especially Vietnamese food which had significantly tak

ASEAN은 2015년 아세안경제공동체(AEC: ASEAN Economic Community)를 출범시켰으나 선발회원국과 후발회원국간 개발 격차(Development Gap)는 여전히 큰 상황이다. AEC가 통합의 효과를 극대화하기 위해서는 ASEAN 6와 격차가 큰 CLMV(캄보디아·라오스·미얀마·베트남)지역의 경제성장이 뒷받침되어야 한다. 우선적으로 메콩 유역국인 CLMV의 교통·통신·에너지와 같은 핵심 인프라의 개선이 필요하며, 메콩유역개발(GMS: Greater Mekong Subregion) 프로그램은 CLMV의 인프라 개선을 통해 ASEAN의 개발격차를 줄이는 핵심 프로젝트로서 의의를 가지고 있다. 본 연구는 GMS의 개발격차를 해소에 대한 기존의 성과를 평가하고, 개발격차를 효과적으로 해소하기 위한 방안을 모색해보고자 한다.
