한국 체육사상에 있어서 風流

박기동 江原大學校附設 體育科學硏究所 1990 江原大學校附設體育科學硏究所論文集 Vol.- No.15

In order to interpret correctly the word "PungRyu(風流)", both the thought of Choi, Chi-Won(崔致遠) who used it first and "PungRyu(風流)" as our own native thought are examined in this study. "PungRyu", our own racial native religion and way of life, is inseperable from "HwaRang(花郞)" and become its thought and way of practice. These are found in the old "JeCheon(祭天)" ceremony. Although "HwaRang" system is disappeared, the spirit of "PungRyu" is revived to overcome the every national crisis. As the root of Korean Physical Education thoughts, "PungRyu", the aim of this study, is good enough, consequently. Besides, it may be suggested that "PungRyu" is worth noticing as Physical Education thought which can show its moral, spiritual aim in modern Physical education thought which can show its moral, spiritual aim in modern Physical education and sport activity. The exertion of our body should "be enraptured" (it means SinMyungNanDa : 神明난다) for the benefit of our community through the "truth"(Cham : 참) and the "zest"(Mub ; 멋)

개의 신내혈류(腎內血流)에 미치는 Isoproterenol의 영향(影響)

박기동,Park, Ki-Dong 대한약리학회 1969 대한약리학잡지 Vol.5 No.2

The direct effect of isoproterenol on renal function, when given intravenously, is usually obscured by its potent hypotensive action. To obviate the latter action, isoproterenol was infused directly into one renal artery of the dog, the other kidney serving as a control for the general action. And following results were obtained. In the first series of experiments, the directic action of isoproterenol was ascertained. $1.0\;{\mu}g/kg/min$. reduced on both kidneys the urine flow, clearances of PAH and creatinine, as well as the amount of sodium excreted, but the effect was weaker on the experimental side than on contralateral side. With $0.1\;{\mu}g/kg/min$., two cases among 6 experiments showed marked diuresis, two cases no apparent effect, and another two marked antidiuresis on the experimental kidney, whereas the contralateral kidney exhibited antidiuresis in all cases. Further reducing the dose unmasked the diuretic action on the ,experimental kidney. In another series, the effects of isoproterenol on the blood flow distribution within the kidney and on sodium concentration gradient within the kidney tissue were observed. $0.05\;{\mu}g/kg/min$ isoproterenol markedly increased the medullary plasma flow and slightly increased total renal plasma flow and glomerular filtration rate, along with concomitant increase in the amount of sodium excreted and osmolar clearance, and decrease in reabsorption of free water. Sodium concentration gradient markedly decreased in the experimental kidney, reaching 2/3 of the value observed in the contralateral kidney at the papilla. It is thus concluded that isoproterenol exerts a diuretic action, when infused directly into a renal artery, and the mechanism of the action rests on its hemodynamic action, substantiated as the increase in glomerular filtration and in the medullary blood flow, resulting in washout of hyperosmolality produced by the coutercurrent multiplier system.

철원군유도 발전과정 : 개인생애사를 중심으로

박기동,윤대중,정현국 한국구술사학회 2015 구술사연구 Vol.6 No.2

본 연구는 지방 소도시 유도의 발전과정을 알아보기 위해 유도인으로 살아온 한 개인의 삶을 살펴보고 철원군유도 발전과정에 대하여 참여자의 경험과 기억을 구술사 연구방법을 통하여 기록화 되지 않은 부분을 문헌으로 정리하는데 연구의 목적이 있다. 본 연구자는 연구 참여자와 몇 차례 만남을 갖고 반구조화 된 면담을 통해 얻어진 자료를 전사하여 분류분석방법을 사용하여 다음과 같은 결론을 도출하였다. 참여자의 삶에서 접한 여러 운동 가운데 유도가 본인의 적성에 가장 잘 맞는다고 판단했다. 고등학교 진학 또한 우연하게 육성종목이 유도인 학교로 진학을 했고, 대한유도학교에 진학했으며, 그곳에서 자신의 유도실력에 대한 실망으로 지원입대를 했다. 전역 이후 고향에 돌아와 어머니와 갈빗집을 운영했으며, 도민체육대회에 참가할 선수를 지도해 달라는 군수의 제안에 선수들을 지도했다. 과거 유도의 불모지였던 그러한 곳에서 2014년현재 10여 명의 국가대표와 상비군을 배출한 배경에는 참여자 활동이 중요하게 작용하고 있었으며, 2015년 전국대회를 개최하는 지역으로 발전했다. 본 연구에서 유도인의 구술을 통해 지방유도사를 들여다보는 기회는 매우 의미 있는 것이며, 강원도유도회 활동과 함께 철원유도의 활동에 대한 후속 연구가 이루어져야 할 것이다. Using the oral history research method, this study examines the life of one person through his achievements in judo (yudo in Korean) and organizes the previously unrecorded parts of the participant’s experiences and memories which led to the development of Cheorwon, a rural city, as a judo center in the Republic of Korea. The researchers conducted several semi-constructed interviews and analyzed the collected data through the classification analysis method drawing the following conclusions. Although the participant was active in many types of exercise in his life, he felt judo was right for him. He unknowingly entered a high school specializing in judo which led him to Daehan Judo College after graduating high school. disappointed by his judo skills at college, he volunteered for military service and after being discharged he returned to his hometown and began to run a restaurant with his mother. It was at this point in his life that a governor of his town asked him to teach judo to the players that would be participating in the provincial sports festival. He began instructing the players and because of the participant’s significant involvement in various activities since then, there were over 10 national representatives and regular players in 2014 alone from Cheorwon, a city where judo was not popular before the participant’s involvement in Cheorwon’s judo scene. Earlier this year, the 2015 National Games were held in Cheorwon making this study a very significant look into the local judo history through an individual’s oral history. A follow-up study should be done on the judo activities of Cheorwon with the Gangwon Judo Association.

Electrically assisted stress relief annealing of automotive springs

박기동,Van Loi Tran,홍성태,정용하,여태식,남민재,김문조,진성우,한흥남 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.8

In the present study, Electrically assisted (EA) stress relief annealing for automotive springs is experimentally investigated. A concept of EA stress relief annealing is to reduce the process time by superimposing the effect of electroplasticity on that of the elevated temperature. In EA stress relief annealing, the temperature of a cold-coiled spring specimen is rapidly increased to the annealing temperature and held constant by a pulsed electric current. The experimental results show that the performance of EA stress relief annealing clearly surpasses that of a conventional stress relief process, even with a significantly shorter process time and a significantly smaller amount of energy. The result of X-ray diffraction analysis confirms that the annihilation of dislocations during EA stress relief annealing is enhanced, which strongly suggests the occurrence of the electric current induced annealing.

H형 슬롯결합 원형편파 마이크로스트립 안테나

박기동 한국통신학회 2011 韓國通信學會論文誌 Vol.36 No.4

본 논문에서는 H형 슬롯결합 원형편파 마이크로스트립 안테나를 제안하였다. 안테나의 크기를 소형화하기 위해 접지면을 가급적 작게 하였다. 전자파 해석 툴인 HFSS를 반복적으로 적용하여 최적의 설계 파라미터 값을 얻었다. H형 슬롯의 구성 파라미터 SL, S1, S2와 방사소자의 코너컷 길이 ΔL이 안테나의 입력 임피던스와 원형편파 특성에 미치는 영향을 검토하였다. 그리고 반사손실, 축비 및 이득 등의 시뮬레이션 결과를 측정결과와 비교하였다. 그 결과 제안한 안테나가 RFID시스템 등 여러 분야에서 충분히 사용될 수 있음을 확인하였다.

RFID 시스템용 유한 접지면을 갖는 소형 원형편파 안테나

박기동 한국통신학회 2011 韓國通信學會論文誌 Vol.36 No.10

본 논문에서는 2.45㎓대역의 RFID 시스템에서 사용할 수 있는 소형 바람개비형 슬롯결합 원형편파 마이크로스트립 안테나를 제안하였다. 안테나의 크기를 소형화하기 위해 접지면을 가급적 작게 하였다. 전자파 해석 툴인 HFSS를 반복적으로 적용하여 최적의 설계 파라미터 값을 찾았다. 제안한 안테나의 핵심 파라미터들이 안테나의 입력 임피던스와 원형편파 특성에 미치는 영향을 검토하였다. 최적의 설계 파라미터들을 적용한 안테나에 대해서는 반사손실, 축비 및 이득 등의 시뮬레이션 결과를 측정결과와 비교하였다. 그 결과 제안한 안테나가 RFID 시스템에서 충분히 사용될 수 있음을 확인하였다.
