        혈관질환 정보관리 시스템

        김동익,김덕경,허세호,이병붕,김용신,김은숙,문지영,도영수,신성욱,김동수,김만태,진재욱,김용신 대한혈관외과학회 2002 Vascular Specialist International Vol.18 No.1

        As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

        우리나라에서 솔껍질깍지벌레의 분포확산

        임유진,이상명,김동수,김준범,최광식,이신혜,박정규,이동운,Lim, Eu-Gene,Lee, Sang-Myeong,Kim, Dong-Soo,Kim, Joon-Bum,Lee, Shin-Hye,Choi, Kwang-Sik,Park, Chung-Gyoo,Lee, Dong-Woon 한국응용곤충학회 2012 한국응용곤충학회지 Vol.51 No.1

        솔껍질깍지벌레는 우리나라 곰솔림의 주요한 해충의 하나이다. 본 연구는 우리나라에서 솔껍질깍지벌레의 분포를 알아보기 위하여 7개도 3개 광역시, 91개 시군구, 686 읍면동의 해송림에서 2010년 밀도를 조사하였다. 5개도 2개 광역시에서 솔껍질깍지벌레가 서식하고 있었는데 시군구별로는 조사대상의 64.8%인 59개 시군구에서 서식이 확인되었다. 솔껍질깍지벌레의 분포는 남해안 전역과 동해안의 포항, 서해안의 충남 보령지역까지 분포하였다. 충북과 대전광역시 및 제주도에서는 솔껍질깍지벌레의 분포가 확인되지 않았다. 부산지역은 16곳의 모든 구에서 솔껍질깍지벌레가 분포하였고, 시군 단위에서는 전남 해남군의 솔껍질깍지벌레 평균밀도가 1.713마리/0.785 $cm^2$로 가장 높았으며 읍면동 단위에서는 해남군 송지면이 6.36마리/0.785 $cm^2$로 가장 높았다. 곰솔 가지 내의 솔껍질깍지벌레 밀도와 솔껍질깍지벌레가 서식하고 있는 빈도와는 높은 상관관계가 있었다(상관계수=0.89). The black pine bast scale, $Masucoccus$ $thunbergianae$ (Hemiptera: Margarodidae), is a serious pest of the Japanese black pine, $Pinus$ $thunbergii$, in Korea. The distribution of the black pine bast scale was examined, looking overall at 686 towns (eup), townships (myeon) or neighborhoods (dong). There were Japanese black pine ($Pinus$ $thunbergii$) forests in 91 cities, counties (gun) and borough (gu), in seven provinces and three metropolitan cities during 2010. Black pine bast scale were found in 64.8% of cities or counties or borough (59) in 7 provinces and 3 metropolitan cities, and were distributed in all South Costal regions, Pohang in East Costal region and Boryeong in West Costal region. Chungcheongbukdo, Daejeon and Jeju did not have black pine bast scale. All the gu regions in Busan had black pine bast scale, of which the area with the highest prevalence was Haenam in Jeollanamdo (1.713 crawlers/0.785 $cm^2$). Songji-myeon had the highest occurrence rate (6.36 crawlers/0.785 $cm^2$) from the towns, township and dong. The density of black pine bast scale in twigs was highly correlated with percentage of the sample with scale (Correlation coefficacy=0.89).

      • Investigation of Optical Intensity Modulator Using Electrically Tunable Reflectiection Grating

        신동수 한양대학교 이학기술연구소 2004 이학기술연구지 Vol.7 No.

        반사 에돌이발을 광병조기로 이용하는 가능성에 대하여 연구하였다. 반사 에돌이발이 전기광학적 도파로에 형성되어 에돌이발의 주기가 전기적으로 조절이 가능하다고 가정하였다. 돠로의 전파손실을 고려하여 반사 에돌이발이 대한 결합모드 방정식을 플었으며, 에돌이발에 의한 빛의 반사유로가 투과율을 여러 개의 결합 계수에 대해 유효굴절율의 변화량의 함수로 보였다. The possibility of utilizing the reflection grating as an optical intensity modulator is investigated. It is envisioned that the reflection grating is formed on an electro-optic (EO) waveguide. As a consequence, the grating period is assumed to be electrically tunable by the EO effect. The coupled-mode equations for the reflection grating are solved with the waveguide propagation loss taken into account. Changes in light reflection and transmission are presented as a function of effective index change for different coupling coefficients. The results show that the waveguide propagation loss can be detrimental in achieving a high-efficiency optical intensity modulator based on the reflection Elating.

      • 축류팬의 소음저감 설계에 관한 연구

        申澈洙,姜宇政,李東勳 충주대 산업과학기술연구소 1994 産業科學論文集 Vol.2 No.-

        This paper is to describe the design of the noise reduction of the axial flow fans. The nature and magnitude of the noise-producing mechanisms and the noise reduction are discussed on the basis of the results and theories published up to now. Sources of noise in axial fans can be classify into rotational and non-rotational noise. Rotational noise which is caused by inflow distortion and turbulence consists principally of tones related to the blade passage frequency. While, non-rotation noise which is caused by an interaction of the blade with the tip clearance vortex is broad band in character. The main parameters investigated for noise reduction in axial fans are as follows ; tip clearance, number of blade, chord length, camber angle, solidty, blade thickness, twisting angle, serrations attached on the blade, rotating shroud attached on the tip blade tip, bellmouth, etc.

      • 포트폴리오 평가와 전통적 평가방법의 비교 연구

        신충린,박기동,오수일 강원대학교 체육과학연구소 2001 江原大學校附設體育科學硏究所論文集 Vol.- No.24

        The purpose of this study is to identify the effects of portfolio assessment on physical education learning in high school. portfolio assessment groups and traditional assessment groups were compared out of factors such as ALT/PE, learning attitude, cognitive thinking capacity, and the change of learning achievement for motor function. 1.Academic learning time in physical education Portfolio assessment groups took part in 17 munite 2 second, 34.07% of whole learning time. Therefore motor engaged time took part in more portfolio assessment groups than traditional assessment groups. 2.Learning attitude 1)Physical education class In portfolio assessment groups affirmative attitude has changed out of factors such as interest, importance, enjoyment, monotony, positiveness, and satisfaction degree. However traditional assessment groups has not. 2)Friendship relation Affirmative attitude has changed out of factors such as relationship and sociability of friendship relation in portfolio assessment groups but in traditional assessment groups it has changed out of factors such as relationship of friendship relation. 3)Physical educator Affirmative attitude has changed out of factors such as fairness, preference, and sincerity of physical educator in portfolio assessment groups, while in traditional assessment groups it has changed out of factors such as fairness and preference of physical educator. 3.Cognitive thinking capacity Cognitive thinking capacity revealed high more portfolio assessment groups than traditional assessment groups. 4.Learning achievement for motor function Learning achievement for motor function revealed a little high more portfolio assessment groups than traditional assessment groups.
