  • Objective : To find the main symptoms associated with atopic dermatitis and to get the utmost out of information about cause, treatment are contribute in the treatment of atopic dermatitis rather than looking for ways through how to connect modern atopic dermatitis and a listed symptom of classic literature. Method : In this research, we recorded about the main symptoms of atopic dermatitis such as itch, erythema, edema, pus and furuncle. Also we interpreted original text by extracting a sentence containing the terms like red[赤], pus[膿], flare[發赤], dermatosis[溞], swelling[洋], light red[紅], itch[瀁], worm running[蟲行], juice[汁], rash[癮疹], variegation[疹斑] and summarized cause of symptoms, disease sign, prescription. Results : There are the cause of many symptoms accompanied by atopic dermatitis in the body that recorded unpreparedness[虛], Wind[風], Fever[熱], unpreparedness & interruption of vitality hole[氣穴不通], unpreparedness & Wind, Wind Fever[風熱], Wind Coldness[風寒], Wind Humidity[風濕], Humidity Fever[濕熱], Wind Humidity Fever, Wind of Lungs[肺風], Wind of Lungs and Spleen[脾肺風], the Kidney Wind poison[腎臟風毒], Wind of Lungs Fever, Worm[蟲], miscellaneous vitality[雜氣], unpreparedness and Fever of Heart[心虛熱], old sore of kidney poison[久瘡腎臟風毒].

  • Across-wind response is often the cause of significant structural vibrations that in turn cause fatigue damage to welded and other connections. The efficacy of low-cost helical strakes to mitigate such adverse response is presented for a traffic signal structure. Field observations are made on a prototype structure in a natural wind environment without and with helical strakes installed on the cantilevered arm. Through continuous monitoring, the strakes were found to be effective in reducing across-wind response at wind speeds less than 10 m/s. Estimates of fatigue life are made for four different geographical locations and wind environments. Results for the class of traffic signal structure show that helical arm strakes are most effective in locations with benign wind environments where the average annual wind speed is not more than the vortex shedding wind speed, which for this investigation is 5 m/s. It is concluded that while strakes may be effective, it is not the panacea to mitigating connection fatigue at all locations.

  • Jeju International Airport is characterized by the occurrence of low-level windshear due to its location, surrounding terrain, and its weather characteristics. Especially the low-level windshear accompanied by tailwinds on both sides of the runway i.e., bidirectional tailwind, is a hazardous weather phenomenon with unique characteristics that are difficult to find at any other airports. This study focuses on bidirectional tailwind occurrence at Jeju International Airport in 2020-2021. As a result, characteristic pressure patterns of the types that cause bidirectional tailwind was identified as it was possible to categorize strong wind types such as 1) strong southwest wind, 2) strong east wind, and 3) strong northwest wind, which do not cause bidirectional tailwind, and wind direction variation types such as 4) bidirectional tailwind, and 5) south wind followed by southwest wind, which cause bidirectional tailwind. The results of this study are expected to contribute to improving aviation safety by enabling aviation operators to predict and take appropriate safety measures based on their understanding of the causes and characteristics of bidirectional tailwind.

  • I studied some important medical liter atures in order to examine the cause of Aphasia and found out some facts as follows : 1. Hwang Je Nae Kgong(黃帝內經) is more referred exogenous causes of disease of Aphasia than endogenous causes of disease. 2. Among many causes of Aphasia, exogenous causes of disease was cinsidered to be most common in Soh Shi Je Byong Won Hu chong Rhon(巢氏諸病源喉總論), which has had a wide influence down the ages. 3. Chon Keum Yo Bang(千金要方), Chi Tae Bhi Yo(外臺秘要), Tae Pyong Song Hye Bang(太平聖惠方), Song Je Chong Rok(聖濟總綠). Bu In Yang Bang(婦人良方) and so forth had been quoted from Hwang Je Nae Kyong and Soh Shi Je Byong Won Hu Chong Ron(巢氏諸病源喉總論). 4. In the ming dynasty had been quoted non-exo-endogenous causes of disease and the Kinds of Aphasia and prescription. 5. In the Choeun dynasty and the Ching dynasty, exogenous causes of disease was confined to the quotation of the books referred to above as well, but endogenous causes of disease was developed. 6. Today is refered kidney and Aphasia. The cause of Aphasia obtained was as follows. The exogenous cause of disease is wind, wind and cold, wind and heat. The endogenous cause of disease is pregnancy, heart block of postpartum, weakness of heart and kidney, impairment of seven modes of emotions, stagnation of phlegm and phlegm-fire, hemorrhage. The non exo-endogenous causes of disease is sing ballads and call out.

  • Wind turbine noise is generally lower than that from other environmental noise sources such as road and railway noise. Nevertheless, some residents living more than 1km away from wind turbines have claimed that they suffer sleep disturbance due to wind turbine noise. Several researchers have maintained that residents near a wind farm may perceive large amplitude modulation of wind turbine noise at night, and this amplitude modulation is the main cause of the noise annoyance. However, to date only few studies exist on the prediction of the amplitude modulation of wind turbine noise. Thus, this study predicts amplitude modulated noise generated from a generic 2.5MW wind turbine. Semi-empirical noise models are employed to predict the modulation depth and the overall sound pressure level of the wind turbine noise. The result shows that the amplitude modulation is observed regardless of atmospheric stability, but the modulation depth in a stable atmosphere is 1~3dB higher than that in an unstable atmosphere near the plane of rotation where the blades move downward. Moreover, using the result of the noise prediction, this study estimates the maximum perceptible distance of the wind turbine noise cause by amplitude modulation. The result indicates that the wind turbine noise can be perceived at a distance of up to 1600m in the range of about 30~60 degree from the on axis in a extremely low background noise environment.

  • Through a literal study upon the cause of epilepsy between east and west medicine, next conclusion have been abtained. 1. The cause epilepsy in the east medicine, congenital embryo disease is due to insufficiency of heart(心虛) or deficiency of heart energy(心氣虛), secondary cause is wind -evil(風), frightness(驚), phlegm(痰), fire(火) 2. The cause epilepsy in the west medicine is divided congenital disease and secondary cause, one is excessive discharge of electricity of the brain have on a central nerve, a digestive organ, a respiratory organ, hamatogenous functions, the other is hereditary it and pathological it. 3. The epilepsy is concerned about the abnormality in five viscera, liver, spleen, heart. 4. In comparison east and west medicine of epilepsy is native factor, or innate primary cause is added to outer cause of wind-evil(風), cold-evil(寒), summer-heat(署), wetness(濕), and inner cause of frightness-terror(驚-恐), seven modes of emotions(七情) and the epilepsy is occurred phlegm(痰), fire(火). It similar that the epilepsy is occurred to structural and functional obstacle in western hereditary and primary cause.

  • 이 연구의 목적은 해륙풍에 대해 초등학생들이 어떻게 인지하고 있는지 알아보는 것이다. 연구를 위해 J시 소재 초등학생 159명을 표집하였다. 연구결과 초등학생들 중 해륙풍과 바람이 부는 이유에 대해 바르게 이해하고 있는 학생은 총 159명 중 45명(29.3%)에 불과했다. 대부분의 학생들은 실험결과를 가지고 그대로 해륙풍의 방향을 설명하였다. 즉 학생들은 실험결과를 가지고 해륙풍을 추리하지 않고 있었다. 학생들은 추론 과정을 거치지 않고 실험결과를 그대로 해륙풍의 방향으로 결론지었다. 이러한 결과는 해륙풍에 관한 바른 이해를 위해 새로운 실험 기구의 개발과 실험과 관련된 학습 과정에서 추리 과정을 강조하여 가르쳐야 한다는 점을 시사해주고 있다.

  • Various pilotis are installed in the lower part of high rise buildings. Strong winds can generate sudden airflow around the pilotis, which can cause unexpected internal airflow changes and may cause damage to the exterior of the piloti ceiling. The present study investigates the characteristics of peak wind pressure coefficient for the design of piloti ceiling exteriors by conducting wind pressure tests on high rise buildings equipped with penetration-type and end-type pilotis in urban and suburban areas. The minimum peak wind pressure coefficient for penetration-type piloti ceilings ranges from -2.0 to -3.3. Minimum peak wind pressure coefficient in urban areas was 30% larger than in suburban areas. In end-type piloti ceilings, maximum peak wind-pressure coefficient ranges from 0.5 to 1.9, and minimum peak wind-pressure coefficient ranges from -1.3 to -3.6. With changes in building height, peak wind pressure coefficient decreases as the aspect ratio increases. Peak wind-pressure coefficient increases with taller pilotis. On the other hand, when piloti height decreases, the absolute value of the minimum peak wind pressure coefficient increases.
