이상준,이종태,이성열,Lee, Sang Jun,Lee, Jong-Tai,Lee, Song-Yol 대한기계학회 1996 大韓機械學會論文集B Vol.20 No.1

Flow velocity was measured by, use of hot wire anemometer. Turbulence intensity was in proportion to mean flow velocity regardless of swirl velocity. And integral length scale has proportional relation with swirl velocity regardless of measurement position. Turbulent burning speed during flame propagation which was determined by flame photograph and gas pressure of combustion chamber was increased with the lapse of time from spark and was decreased a little at later combustion period. Because of combustion promotion effect, turbulent burning speed was increased according to increase of turbulence intensity. Burning speed ratio i.e. ratio of turbulent burning speed ($S_BT$) to laminar burning speed ($S_BL$) was found out by use of turbulence intensity u' and integral length scale $l_x$ , $\delta_L$ is width of preheat zone in laminar flame.

Enhancement of the ignitability was necessary to realize the lean burn engine. The characteristics of multiple-spark capacitor discharge igniter(MSCDI) usefulness of which for lean burn was examined in constant volume combustion chamber and evaluated in spark ignition engine. Noise of MSCDI for engine was restricted by adoption of low voltage control system. It was found that the adaptability for high engine speed was remarkable. Lean limit in engine with MSCDI was extended 10% than conventional coil ignition system. Also maximum brake thermal efficiency was almost enhanced 1%.

배경잡음 자료를 이용한 국내 가속도 관측망의 방위각 보정값 측정

이상준,Lee, Sang-Jun 한국지구과학회 2021 한국지구과학회지 Vol.42 No.2

기상청에서 운용하는 268개의 가속도 관측망에 대한 방위각 보정값을 측정하기 위해 배경잡음 교차상관 방법을 사용하였다. 이 방법은 배경잡음 자료를 사용하기 때문에 원거리 지진자료를 사용하는 방법과 달리 특정 조건에 맞는 지진을 선정할 필요가 없고, 한반도와 같은 조밀한 관측망에 적용하여 단기간의 연속 파형 자료만을 사용해 신뢰할 수 있는 방위각 보정값을 측정할 수 있다. 계산에는 2020년 1월부터 2020년 2월까지 총 268개의 기상청 가속도 관측망에 기록된 3성분 연속 파형 자료를 사용했다. 계산된 결과를 보면 기존에 원거리 지진자료를 사용한 결과와 매우 유사하며, 기존 결과에서 누락된 가속도 관측소들을 포함한 대부분 관측소의 방위각 보정 계산 결과가 표준편차 5° 이하로 안정적으로 계산되는 것을 확인할 수 있다. 따라서 본 연구를에서 사용한 방법을 활용해 기상청 가속도 관측소에 대한 방위각 보정값을 지속적으로 모니터링하고 측정된 결과를 활용하면, 가속도 자료의 수평 성분을 활용한 다양한 연구들에 활용할 수 있을 것이다. Orientation corrections for the total of 268 accelerograph stations of the Korea Meteorological Administration (KMA) were estimated using ambient noise cross-correlation. As this method uses ambient noise data instead of teleseismic waveforms from earthquakes under certain conditions, reliable orientation corrections can be obtained using only two-month long continuous seismic data from dense seismic networks in the Korean peninsula.Three-component continuous data recorded at the 268 accelerograph stations from January to February 2020 were used to estimate orientation corrections. The results are comparable to the previous results obtained from teleseismic waveforms; the overall standard deviations of the orientation corrections are less than 5°. Therefore, orientation corrections for the accelerograph station network can be tracked periodically by the ambient-noise method and the result can be used in various studies using the horizontal-component of acceleration data.

Objectives In this study, the authors evaluated the correlation between levels of serum lipid, homocysteine, and folate with volumes of hippocampus, amygdala, corpus callosum, and in patients with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease (AD) type. Methods The study recruited patients who visited the dementia clinic of Haeundae Paik Hospital in Korea between March 2010 and June 2014. Among those, patients who had taken the neurocognitive test, brain magnetic resonance imaing, tests for serum lipid, homocysteine, folate, and apolipoprotein E (APOE) genotyping and diagnosed with aMCI or AD were included for analysis. Bilateral hippocampus, entorhinal cortex, amygdala and corpus callosum were selected for region of interest (ROI). The cross-sectional relationships between serum lipid, homocysteine, folate and ROI were assessed by partial correlation analysis and multiple linear regression analysis. Results In patients with aMCI, old age (> 80) and APOE ${\varepsilon}4$ carrier were associated with AD [odds ration (OR) : 12.80 ; 95% confidence interval (CI) : 2.25-72.98 and OR : 4.48 ; 95% CI : 1.58-12.67, respectively]. In patients with aMCI or AD, volumes and thickness of ROI were inversely correlated with levels of serum lipid and homocysteine. In multiple linear regression analyses, higher total cholesterol level was related to lower left, right hippocampus volume and left amygdala volume ; higher low-density lipoprotein cholesterol was related to lower right entorhinal cortex thickness ; higher homocysteine level was related to lower corpus callosum volume. Conclusions Higher serum lipid and homocysteine levels are associated with decreased volume of hippocampus, amygdala, corpus callosum and entorhinal cortex thickness in patients with aMCI or AD. These findings suggest that serum lipid and homocysteine levels are associated with AD as a modifiable risk factor.

이상준,김병섭,Lee, Sang-Jun,Kim, Byung-Sup 한국원예학회 2012 원예과학기술지 Vol.30 No.2

본 시험은 고추의 육종을 위한 병 저항성 고추를 선발하고자 하였다. 국내에서 시판중인 역병 저항성 품종인 PR계통 21품종, 미국에서 도입해온 36품종과 역병감수성 품종인 '슈퍼마니따'를 사용하여 역병, 탄저병, 흰가루병의 병 저항성 검정을 수행하였다. $Phytophthora$ $capsici$에 의해 발병하는 고추역병의 유묘검정은 서로 다른 교배형(A1, A2, Sterile)을 가지는 3 균주를 사용하여 접종하였다. 그 결과 대부분의 PR계통 고추들은 각각의 교배형에 대하여 저항성 또는 중도저항성을 나타내는 것으로 조사되었다. '역강홍장군'은 서로 다른 교배형의 세 가지 균주에 대하여 저항성을 나타냈으며, 'PR-다따'와 'PR-마니따'는 각각의 교배형에 저항성 또는 중도저항성을 보였다. 외래종의 경우, 'NuMex J.E.Parker', 'Omni Color'과 'SCM-334' 품종은 세 가지 균주에 저항성을 나타냈고, 'Sweet Banana'와 'Tabasco'를 포함한 몇몇 품종들은 각각의 균주에 중도저항성을 나타냈다. 흰가루병에 대하여 'Orange Habanero', 'black Cuban'은 저항성을 나타냈으며, '슈퍼마니따'와 'PR 금동'은 중도저항성을 나타냈다. 'Santa Fe Grnade', 'NuMex Pinata' 품종은 흰가루병에 매우 심한 감수성인 것으로 조사되었다. 탄저병의 경우, 'Aji Limon'과 'C. baccatum var. pendelum 3-4' 품종은 저항성인 것으로 조사되었다. 'Pobalno', 'Omni Color', 'Negro', 'Mesilla', 'Mulato', 'Bhut Jolokia', 'Big Dipper', 'Black Cuban', 'NuMex Pinata'와 'NuMex Big Jim'은 중도저항성을 나타내는 것으로 조사되었다. '태산'을 제외한 대부분의 PR계통들은 탄저병에 대하여 감수성 내지 심한 감수성인 것으로 확인되었다. 본 연구에서 확인된 저항성 개체는 이후에 고추 병저항성 육종에 유용한 유전자원으로 이용될 수 있다. For initiation of resistance breeding program of the red pepper, 21 PR ($Phytophthora$ resistance) cultivars, 36 cultivars collected from USA and 'Supermanitta' which is a susceptible cultivar against phytophthora blight were assayed against phytophthora blight, powdery mildew, and anthracnose. For seedling assay of phytophthora blight, three different mating type strains of $Phytophthora$ $capsici$ were used (A1, A2, Sterile). The result showed that most of the pepper of PR cultivars were resistance or moderately resistance at each mating type. 'Yeokganghongjanggun' was resistant to all three $P.$ $capsici$ strains and 'PR-Datta' and 'PR-Manitta' were resistant or moderately resistant at each type. In case of the collected cultivars, 'NuMex J.E.Parker', 'Omni Color', and 'SCM334' were resistant to all the three types and some cultivars including 'Sweet Banana' and 'Tabasco' were moderately resistant to each type fungi. 'Orange Habanero' and 'Black Cuban' were resistant to powdery mildew and 'Supermanitta' and 'PR Keumdong' were moderately resistant, while 'Santa Fe Grande', 'NuMex Pinata' and 'Puya' were very susceptible. In the case of anthracnose, 'Aji Limon' and 'Capsicum baccatum var. pendulum 3-4' were resistant and 'Pobalno', 'Omni Color', 'Negro', 'Mesilla', 'Mulato', 'Bhut Jolokia', 'Big Dipper', 'Black Cuban', 'NuMex Pinata', and 'NuMex Big Jim' were moderately resistant. The most PR cultivars except 'Taesan' were susceptible or very susceptible. These resistant individuals identified through this experiment can be used as sources of resistance to pepper pathogens in the future breeding programs.
