Periodic paralysis is a group of diseases of unknown cause characterized byrecurrent attacks of weakness or paralysis of the limb muscles, accompanied byloss of deep reflex and failure of the muscles to respond to electrical stimulation. We have experienced a case of periodic paralysis in a 42 years old male who had frequent attacks of flaccid paralysis of the trunk and limb muscles. The diagnosis was easily established by clinical features and electromyographic findings. We found that his plasma renin activity was high during and after attack. But its significance in periodic paralysis was unclear.

Traction Control Using a Disturbance Observer for Hybrid Electric Vehicles

김상준,Sung Hoon Yu,이형철 한국자동차공학회 2021 International journal of automotive technology Vol.22 No.6

This paper presents a practical approach designing a traction controller based on disturbance observer (DOB) in hybrid electric vehicles (HEVs). To conduct the traction control of HEVs, the proposed control scheme estimates disturbances in a specific frequency range caused by wheel-slips and reduces driving force in accordance with the estimated disturbance. A band pass filter is employed to the DOB to extract the disturbance in a specific frequency range causing wheel slip. In addition, a proportional-integral (PI) type regulator is applied to effectively reject the disturbances. To validate the proposed control algorithm, actual vehicle tests are performed using a C-segment HEV sport utility vehicle (SUV). The test results show that the proposed control algorithm achieved more enhanced energy efficiency as well as better ride comfort with maximizing traction force than the conventional control algorithm.

Creeping Bentgrass의 생육을 위한 예지물 발효 액상비료의 효과

김상준,김두환,이상국 한국잔디학회 2011 Weed & Turfgrass Science Vol.25 No.2

Organic fertilizers are divided into natural organic and synthetic organics. The benefits of natural organic fertilizer were reported from the previous researches. However, the limited research results about clippings as a source of natural organic fertilizers were reported. The objective of the research to investigate effects of liquid fertilizer produced from fermented clippings for creeping bentgrass growth. Liquid fertilizer (LF) produced was used for the research to be compared with Urea and two natural organic fertilizers of different source (NO-1 and NO-2). Creeping bentgrass (Agrostis stolonifera L., L-93) was used for the study. Turfgrass quality was measured by visual evaluation every two weeks from June to October, 2011 using a scale of 1 to 9 (1=worst, 6=acceptable, and 9=best). Turfgrass disease damage was measured by percent of area damaged when a turfgrass disease occurred. LF produced lower damage than NO and urea when temperature was high. Although NO-2 produced the highest or equal to the highest turfgrass quality in June and October, LF had the highest or equal to the highest quality from July to September. 유기질비료(Organic fertilizer)는 천연유기질(Natural organic)비료와 합성유기질(Synthetic organic) 비료로 구분이 된다(Christians, 2011). 천연유기질비료의 장점은 그동안의 선행연구를 통해서 많이 보고되어왔다. 그러나 예지물을 이용한 시비효과에 대한 연구결과는 제한적이다. 본 연구는 예지물을 발효시켜 제조된 천연유기질비료로서의 액상비료가 putting green에 많이 사용되고 있는 Creeping bentgrass 생육에 미치는 영향을 알아보기 위해서 수행하였다. 액상비료는 Kentucky bluegrass로부터 수거된 예지물을 모아 부숙과정 없이 미립자로 분쇄한 후 28oC에서 약 2개월간 발효시킨 후 생성된 발효액에 유용미생물(Effective Microorganism,EM) 군으로 제조된 활성액을 3% 혼합하여 제조하였다. 잔디에 대한 각 질소의 시비효과는 National Turfgrass Evaluation Program (NTEP)에서 제시한 방법에 준하여 잔디의 품질을시각적평가를 통해 매 2주마다 조사하였다(1=worst, 9=best,and 6=acceptable). LF와 NO와의 비교에서 고온기간인 8월 20일과 9월 3일에 각각 LF가 NO에 비해 더 좋은 품질을 보여주었다. Urea가 고온기간에 비료피해가 나타난것에 비교하여 LF의 경우 고온기간동안 비료피해가 나타나지 않았다.

Open access status of journals and articles in Journal Citation Reports

김상준,박계숙 한국과학학술지편집인협의회 2021 Science Editing Vol.8 No.1

Purpose There is somewhat of a difference between understanding the open access (OA) concept and practicing it by stakeholders. OA articles are mainly published by gold and hybrid OA journals, but the OA status may be confusing depending on the target databases. This study investigated the OA status of journals and articles and evaluated the extent to which OA2020 (publishing 90% of articles as OA) was achieved. Methods This study collected OA data by combining 2014-2019 data from Journal Citation Reports at the journal level with Web of Science at the article level. Finally, 12,449 journals were analyzed focusing on gold and hybrid OA journals, and progress towards the goal of OA2020 was evaluated. Results Even though 80.4% of Journal Citation Reports journals were gold and hybrid OA journals, only 20.9% of the articles were OA (gold OA journals, 16.6%; hybrid journals, 4.3%). The compound annual growth rate of the total articles was 4.7%, that of OA articles was 16.4%, and that of subscription articles was only 1.7%. Among the subscription journals, 77.4% had shifted to become hybrid journals, but only 5.2% of their articles were OA. Therefore, the hybrid journals were at the very early stage of OA publishing. Conclusion Considerable progress must still be made to achieve the goal of OA2020. The influence of OA publishing will eventually expand and therefore, librarians should take interest in OA publishing for the library services.

PECVD 방법으로 성장시킨 DLC 박막의 복소굴절율 및 성장조건에 따른 박막상수 변화

The complex refractive index of Diamond-like Carbon (DLC) thin films, which can be applied to optical devices or electrical devices, have been determined using optical methods. DLC thin films are grown on Si(100) substrates and vitreous silica substrates respectively, using the technique of plasma enhanced chemical vapor deposition (PECVD). The spectroscopic ellipsometry data($\psi$, $\Delta$) and the transmission spectra of these DLC films are obtained. These optical spectra are analyzed with the help of the Sellmeier dipersion relation and a quantum mechanically derived dispersion relation. Using spectroscopic ellipsometry data at their transparent region, the refractive index and the effective thickness of DLC films on vitreous silica are model calculated, Then the transmission spectra are inverted to yield the extinction coefficient spectra k(λ) at absorbing region. These spectra are fit to the quantum mechanical dispersion relation and the best fit dispersion constants are determined. The complex refractive indices are easily calculated with these constants. The spectroscopic ellipsometry data at the absorbing region in model calculated to give the packing densities and the degrees of surface microroughness of DLC films. Discussions are made in correlation with the growth condition of DLC films. 광학소자나 전자소자의 코팅에 많이 이용되고 있는 Diamond-like Carbon(DLC) 박막의 복소굴절율을 광학적 방법을 사용하여 구하였다. PECVD(Plasma enhanced CVD)법에 의해 Si(100)기판과 비정질실리카 기판위에 각각 성장시킨 DLC 박막을 분광타원해석기와 분광광도계를 이용하여 타원해석 스펙트럼과 광투과율 스펙트럼을 측정하고, Sellmeier 분산관계식과 양자역학적 진동자 모델을 이용하여 분석하였다. 비정질실리카 위에 증착된 DLC 박막의 광투과영역에서 분광타원해석분석으로 굴절률 및 박막의 유효두께를 구하고 광흡수영역에서 투과스펙트럼을 역방계산하여 소광계수를 구한 뒤, 이 소광계수 스펙트럼에 최적 근사하는 양자역학적 분산식의 계수들을 회귀분석법으로 결정하여 복소굴절율을 구하였다. 그리고 모델링방법을 타워해석 스펙트럼에 적용하여 Si기판과 비정질이산화규소 기판위에 증착된 DLC 박막의 조밀도, 표면거칠기 등 박막상수를 박막의 성장조건에 따라 분석하였다.

Antenna Selection Schemes in Quadrature Spatial Modulation Systems

김상준 한국전자통신연구원 2016 ETRI Journal Vol.38 No.4

This paper presents antenna selection schemes for recently proposed quadrature spatial modulation (QSM) systems. The antenna selection strategy is based on Euclidean distance optimized antenna selection (EDAS). The symbol error rate (SER) performance of these schemes is compared with that of the corresponding algorithm associated with spatial modulation (SM) systems. It is shown through simulations that QSM systems using EDAS offer significant improvement in terms of SER performance over SM systems with EDAS. Their SER performance gains are seen to be about 2 dB–4 dB in Es/N0 values.
