정완수,박지현,정치봉 순천향대학교 기초과학연구소 1999 순천향자연과학연구 논문집 Vol.5 No.1

본 논문에서는 한국의 초 중등 수학 교육의 변화의 방향을 제시하였다. 수학 교육의 새로운 변화의 필요성과 당위성을 수학의 본질적인 특성에서 살펴보았다. 이러한 수학에 대한 교육적인 전망에서 유도되는 자연스런 수학 교육이 필요로 하는 교수 학습 모형과 계산기 및 컴퓨터 등의 기술공학의 교육적 사용에 대하여 고찰하였다.

공급 사슬 환경에서의 고객주문만족 시스템

장지홍,정호상,정봉주 연세대학교 산업기술연구소 2000 논문집 Vol.32 No.2

기업의 틀을 뛰어넘어 고객과 공급자까지 자사를 중심으로 통합하는 공급 사슬 환경에 있어서 고객 만족 수준을 향상시키는 것은 매우 중요하다. 고객 만족 수준을 높이기 위해서는 우선 정확한 수요예측을 통하여 주문에 대비해야 하며, 주문이 들어올 경우 고객에게 정확한 납기회신을 제공해야 한다. 물류, 정보, 자금 등의 흐름을 총괄하는 공급 사슬 환경의 특성상, 정확한 수요예측과 납기회신을 제공하기 위해서는 제품의 공급자, 고객을 포함한 공급 사슬내의 여러 파트너 들에 대한 종합적인 고려가 이루어져야 한다. 본 연구에서는 일반적인 공급 사슬 환경에서 사용 가능한 수요계획 시스템을 구축하는데 필요한 모델과, 고객의 주문에 대한 납기 제시를 위한 납기회신 알고리듬을 제시하고자 한다. : 공급사슬관리, 수요계획, 납기회신

鄭漢鍾,蔣址圭,丁小鳳 진주산업대학교 1985 論文集 Vol.23 No.-

The basic purspose of this study was to measure of physique, physical strength and peronality of high school boxer. Above three type tests were given to the outstanding boxer of 50(10 of fly weight, 10 of bantam weight, 10 of feather weight, 10 light weight, 10 of welter weight) who participated in reinforced training camp prepared for the national game in 1984. Physique tests were standing height, body weight, chest circumference sitting height, uperlimb length and hip circumference. Physical strength tests were grip strength, situps, 3㎞ runing, standing board jump, 100m sprint, shuttle run, Burpee test, Trunk flexion and Trunk extention. Personality tests were general activity, Dominance Emotional stability, Impulsiveness, Masculinity, Objectivity, Reflectiveness and Sociality. The result of this study pointed out the followings; 1. Physuque measure: The fly weight of right boxer's standing height 2㎝ of average thean left boxer. feather weight of left boxer is standing height 2㎝ of average than right Boxer. Bantam, light weight of left boxer's chest circumference 5㎝ of average than right boxer. 2. Physical strength measure; The fly weight of right boxer's Trunk flexion 3㎝ of average than left boxer. welter weight of right boxer's Trunk extention 1.4cm of average than left boxer.

지봉기,김태우,김정호,김중석,주진호 成均館大學校 科學技術硏究所 1998 論文集 Vol.49 No.1

We evaluated the effects of processing variables on interface irregularity. microstructure. and resultant Jc of BSCCC superconductor tape. For the tapes made by PIT technique. the degree of interface irregularity was varied with powder packing methods and forming process variables. It was observed that the degree of interface irregularity of the tape by CIP method was more reduced. compared to that of the tape by ram method. In addition. the degree of interface irregularity was promoted with decreasing the dimension of tape during forming process. As the dimension of wire/tape were changed from diameter of 3.25mm to thickness of 200㎛ during forming process. Jc value was observed to be increased by 10 times. It was likely that the improvenment of Jc was mainly result from the enhanced texturing of 2223 grain. Microstructural investigation showed the degree of texturing was degraded by the existence of both second phases and interface irregularity. If the interface was flat, larger grain size and better texturing near interface were developed compared to those inside superconducting core, The improvements of microstructure near interface may be result of reaction between Ag and superconductor phase.

정명철,김호성,김경철,노지현,고재환,김용봉,권동일 白中央醫療院 2005 仁濟醫學 Vol.26 No.1

Postpartum hemorrhage remains one of the leading causes of maternal deaths. The major causes of postpartum hemorrhage include uterine atony, retained placental fragment, placenta accreta, and lower genital tract lacerations. Conservative treatment is based on administration of uterotonic drugs, vaginal packing, and surgical repair of genital tract lacerations. When bleeding fails to respond to conservative treatment, surgical ligation of uterine vessels or hemostatic hysterectomy is performed. We present a case of postpartum bleeding treated by selective uterine arterial embolization with a brief review of previous literatures of postpartum hemorrhage & uterine arterial embolization.

택지개발지구내 도시공원의 분포특성에 관한 연구

김수봉,정응호,김정환,류지원 한국정원학회 2002 한국전통조경학회지 Vol.20 No.2

To generate a suggestion for a better framework especially the distribution and locations of urban parks in residential areas, ‘residential site development districts’ in Daegu city were tested based on the community involvement and user’s demand for visting. Service-range, advantage and disadvantage in use derived from the locations of the parks in the districts were analyzed according to the concept of density,character assessment, structure in the distribution and locations. Suggestions to give residents more friendly surroundings with ’easy access’ and ’friendly characteristics of each parks’ are as follows; ⅰ) Although most of the tested sites are satisfying the legal criterion on the required level of size of urban parks in each district, there are big difficulties to have rich natural environment in the case of extensive size of residential sites due to too low applied-criterion(0.6㎡ per person) which is a minimum requirement. ⅱ) Although the rate of size of parks in the sites were gradually improved recently, the portion for each person had not improved at all. Therefore, it is needed that new detailed criteria in different level rooted in the character of individual sites such as population and characteristics of parks. ⅲ) Although the distance of parks is within the range of use, the locations are on the edge of sites and residential districts where is not on the everyday route. Therefore to give more easy accessibility, the urban parks in the residential sites should be located on the daily life route where is a more common area in future plans.

The aim of this study is to establish environment-friendly planning principles of the apartment complex. This paper firstly identities the key issue concepts of 'environment-friendly.' It extracts planning items and principles through the literature review on environment-friendly and examplary cases in the world. It then constructs a framework to establish planning principles by classifing planning elements focused on the six major issues(efficiency land use, reflection of variety and ecology, harmony between the nature and human beings, amenity, circulation of energy and resources, amount used decrease of energy and resources). Finally, the research established the planning principles by the expert survey. The results of this study can be used as the gradual principles for the development of environment-friendly apartment complex.

2006년 국내 각 지역으로부터 수집된 재래종옥수수 유전자원을 관행방법에 의해 파종하고 주요특성별로 분포도를 살펴본 결과는 다음과 같다. 1. 수집된 유전자원에 대한 발아율은 대부분 80∼100%이상의 분포를 보였으나, 일부 수집계통에는 30% 미만의 극히 저조한 발아율을 보였다. 2. 수집자원에 대한 초기생육을 살펴보면 극히 생육이 저조한 것이 40% 정도를 보였고, 극히 우수한 자원은 3%미만으로 나타났다. 3. 간장은 대부분이 150∼199cm범위에 55%가 분포하고 있었으나, l00cm이하가 5%, 250cm이상이 8%로 나타나 수집종간에 큰 차이를 보였다. 4. 주당 분얼수는 1개 미만이 40%의 분포를 보였으나, 일부 수집종에서 2 내지 3개의 분얼수를 보이는 계통이 확인되었다. 5. 개화소요일수는 61∼64일의 범위에서 40%, 57∼60일의 범위에서 30%의 분포를 보였으며, 특히 일부 수집종의 경우 55일 이하의 극조생종도 10% 정도의 분포를 보였다. 6. 이삭길이는 대부분 11∼15cm범위에 60%가 포함되어 있으나, 일부계통에서 5cm미만이 2%, 16∼20cm의 이삭길이도 10%가 분포하였다. Germination ratio on the 300 collected genetic resources showed 80 to 100 percentage, but those of some accessions were very low as below 30 percentage. Early growth phase of most of these lines were very poor while some collected lines were very vigor. Range of stem height showed from 150 to 199cm, but that of some accessions showed below 100cm as five percentage and some of them was over 250cm as eight percentage. Number of tillers per plant appeared less one but some collected lines have two to three tillers per plant. In days to tasseling, some accessions showed more four per plant. Ear length of these accession showed above 60 percentage as 11 to 15cm, while that of some collected lines showed over 10 percentage as 16 to 20cm.

다발성 말초신경병증으로 발현한 Churg-Strauss 증후군 1예

이지현,김종국,유봉구,김민정,김광수 KOSIN UNIVERSITY COLLEGE OF MEDICINE 2006 高神大學校 醫學部 論文集 Vol.21 No.1

Churg-Strauss syndrome (CSS) is defined by eosinophil-rich and granulomatous inflammation of the respiratory tract and necrotizing vasculitis affecting small to medium-sized vessels, associated with asthma and eosinophilia. It is strongly associated with antineutrophil cytoplasmic antibodies, especially the anti-myeloperoxidase type (p-antineutrophil cytoplasmic antibodies) are most often found in CSS. Neurologic involvement is common and may develops early in patients with CSS, usually manifestings as peripheral neuropathy especially mononeuritis multiplex. We report a 58-year-old woman of Churg-Strauss syndrome presented with distal asymmetric polyneuroapthy, which has been reported rarely.
