姜英豪,金仁達 서울大學校 保健大學院 1968 公衆保健雜誌 Vol.5 No.2

A study was conducted by the author in September 1968 towards the infants and young children in some underprivileged rural villages of Korea by employing such methods as clinical assessment, nutritional biometry, and biochemical tests, in an attempt to evaluate their nutritional status with possible reference to protein calorie malnutrition (PCM). The infants and young children examined totaled 232 of whom 111 were boys and 121 were girls. The results are as follows: Ⅰ. Clinical Assessment The prevalence rates of the signs suggestive of PCM turned out to be as below : 1) Cases with dyspigmented hair were observed with 4.5% of the 45 infants examined. and 18.8% of the 187 young children examined. Cases with thin and sparse hair were seen with 22.8% of the infants, 14.0% of the young children, and l5.2% of both the infants and young children. 2) Prevalence of the pale conjunctiva rated 28.6% of the infants. 32.3% of the young children, and 30.4% of both the infants and young children. 3) Keratomalacia cases were found in 0.5% of the young children only and they corresponded, in turn, to 0.4% of the whole examined. 4) Cases with angulostomatitis rated 14.0% of the young children only, who constituted 10.0% of the total examined. 5) Those with moon-face were observed only with 2.3% of the infants, rating 0.4% of the total. 6) Cases with flaky-paint dermatosis were observed with 2.3% of the infants, 0.5% of the young children, and 0.9% of both the infants and young children. 7) Those who were found to have such skin lesions as fissure of the ear lobe, tender sores, or moist groin rash rated 15.9% of the infants, 20.4% of the young children, and 19.6% of both the infants and children. 8) Rate of those with muscles wasted was 11.4% of the infants, 25.8% of the young children, and 23.0% of both the infants and young children. 9) Those with edema were observed only with 0.5% of the young children. rating 0.4% of the total. 10) Psychomotor changes (apathetic, miserable, inert, withdrawn, or anorexic) rated 7.0% of the young children only, and 5.7% of the whole examined. 11) Prevalence rate of diarrhea precipitating dehydration and such other conditioning infections as thrush was found to be 20.5% of the infants, 7.5% of the young children, and 10.0% of both the infants and young children. 12) The results of clinical assessment led the author to the following findings: (1) Those corresponding to 29.1% of the whole examined had one or two combined signs suggestive of PCM. (2) Those with three or more signs combined rated 1.3% of the total children examined. (3) No clinically obvious kwashiorkor was found, but each of the component signs which, in constant combination, characterize it (edema, muscle-wasting, and psychomotor changes) was separately observed mainly with the young children as presented in table 2. (4) Those who impressed the author with clinically obvious nutritional marasmus were 6.7% of the infants, 3.2% of the young children, and 3.9% of both the infants and young children. Ⅱ. Nutritional Biometry 1) The mean heights. weights, chest circumference, and head circumference obtained were as shown in table 3. 2) The mean triceps skin-fold thickness, upper mid-arm-circumference. and upper-mid-arm-muscle circumference were as presented in table 4. 3) Distribution of the heights by four levels of 10% intervals indicated underweights in the light of Korean general standard, as shown in table 10. 4) Distribution of the weights contrasted likewise with the Korean general standard were as shown in table 11. 5) The underweights demonstrated by cases of mild-moderate PCM computed at four levels of 10% intervals as against the Korean general standard, rated 42.2% of the infants, 42.8% of the young children, and 42.7% of both the infants and young children. by the criteria Dr. Jelliffe suggested ??. The severe PCM cases were comprised 31.1% of the infants, 7.5% of the young children. and 12.1% of both groups of them. In the light of the above rates, more than a half of the children examined were found to be affected with PCM ascribable to deficiency of both the protein and calorie. 6) The cases with "Chest circumference/Head circumference Ratio being below 1 after the first 6 months of life" suggestive of the wasting of pectoral muscles which is attributable to PCM corresponded to 57.1% of the infants, 25.1% of the young children, and 29.3% of both the infants and young children as shown in table 13. Ⅲ. Biochemical Tests 1) Hemoglobin levels were found to be anemic (level less than 10.8gm%) with 13.8% of the 80 children examined as presented in table 5. 2) Serum total protein and serum albumin levels were as shown in tables 6 and 7, respectively. The serum albumin levels turned out to be normal with 75.9%, and "low"(2.80gm%∼3.51gm%) with 24.1% of the examined. No deficiency level (less than 2.80gm%) was found among the 29 children. 3) Serum iron content and total serum iron-bindin capacity (TIBC) were as shown in table 8. The deficiency levels of serum iron content less than 50 microgram % comprised 33.3% of the 21 children examined. Those corresponding to 25% and 75% of the 16 children examined had values of TIBC within normal range (300 microgram %∼400 microgram %) and values below the normal range (less than 300 microgram %), respectively, and no case exceeded over the range of normality inspite of the low serum iron content, suggesting the possible ascription to chronic protein deficiency ??. 4) "Urinary Urea-nitrogen / Creatinie-nitrogen excretion Ratios" regarded as an approximte index of dietary adequacy related to muscle storage of protein were obtained as presented in table 9. The cases with the ratios "30 or less" (an indication of malnutrition related to dietary adequacy of protein) rated 58.8% of the 34 children examined.

최정철(Jeong-Chul Choi),박기찬(Kichan Park),김영달(Young-dal Kim),박재홍(Jae-hong Park) 한국경영학회 2021 Korea Business Review Vol.25 No.신년 특별호

본 사례연구는 보안장비분야 세계 정상에 오른 창업가의 끊임없는 창조와 혁신의 경영철학과 사업성장의 역정을 살펴보는 데 목적이 있다. 그룹의 모태가 되는 IDIS는 김영달 대표이사가 KAIST 전산학과 박사과정 중 창업하여 세계 최초로 DVR(Digital Video Recorder)제품을 개발하는 등 보안 분야 디지털 기술을 선도하고 있다. 특히 미국항공우주국(NASA) 등 하이엔드 시장에 진출하는 과정에서 기술력을 인정받아 2000년 시드니 올림픽 주경기장과 오페라하우스 전역에 최첨단 보안장비를 설치함으로써 전 세계에 IDIS의 기술력을 알렸다. 그리고 디지털 전환(Digital Transformation) 시대로 패러다임이 급속히 변화하는 환경에서 보안 분야를 주도함으로써 마침내 세계 정상에 올랐다. 무엇보다 보안 분야 세계 정상에 오른 기업의 최고경영자로서 김영달 대표가 새롭게 도전하고 있는 그의 ‘철학이 있는 경영’, 바로 혁신을 꿈꾸는 엔지니어에서 ‘사회적 부’를 창출해 가는데 기여하는 기업가가 되려는 노력은 IDIS그룹의 경영성과에 의해 증명되었다. 성과분석에 있어서도 “기업의 규모가 성장하면 사회적 책임과 역할도 확대되어야 하므로 좋은 일자리를 만들고 구성원의 행복과 지역사회의 발전을 지속적으로 견인해야 한다”는 그의 ‘안정기반 성장전략’에 초점을 두었다. 정상에 오른 기업으로서 IDIS그룹이 보여준 성장전략과 경영성과는 다음의 세 가지로 요약된다. 첫째, 문어발식으로 규모를 확대하는 것이 아니라 일자리 창출과 고용안정 등 사회적 부를 창출하기 위한 전략으로 관련 다각화 M&A를 신중하게 진행했다. 둘째, 창업을 결심했을 때처럼 ‘국내 기술로 글로벌 넘버원이 될 수 있는 기업’을 찾아 M&A를 추진한 결과, 산업용 디스플레이를 개발하는 ㈜코텍, 프린터 관련 기업 ㈜빅솔론과 IDIS의 사내벤처로 창업한 아이디피(주)를 결합하여 사업의 포트폴리오를 성공적으로 구축했다. 셋째, ㈜코텍, ㈜빅솔론의 창업주들이 직접 김영달 대표를 찾아와 인수합병을 제안했고 M&A 이후 R&D 기술력 기반으로 성장시켜가고 있다. 본 사례연구를 위해 다섯 번의 인터뷰와 20시간이 넘는 질문과 토의 중에서도 밝은 미소와 사업에 대한 열정을 잠시도 잃지 않는 그의 인간적 매력 또한 이를 증명해 주었다. The purpose of this case study is to examine the mechanism of successful business growth of an entrepreneur with his philosophy in creativity and innovation. IDIS was founded by CEO Young-dal Kim and its founding members while attending the Ph.D. in Computer Science at KAIST Graduate School. They developed the worlds first DVR product, and are currently leading digital technology in the field of security. In particular, in the process of advancing to high-end markets such as NASA, technological prowess was recognized, and state-of-the-art security equipment was installed throughout the Opera House from the main stadium of the ‘2000 Sydney Olympics’. Since then, the world has begun to be interested in IDIS technology. IDIS finally reached the top of the world by leading the security field in an environment in which the paradigm to the era of digital transformation is rapidly changing. The core of this case is to look at his “management with philosophy” that CEO Kim is taking on a new challenge as the CEO of a company that has reached the top of the world. He now wants to become an entrepreneur who contributes to creating ‘social wealth’ from an engineer who dreamed of innovation. In other words, his philosophy is that social responsibilities and roles should be expanded as the size of a company grows, and companies should continuously create quality jobs and lead the happiness of members and the development of local communities. The strategy and achievements of IDIS Holdings as a top-rated company are summarized in the followings. First, CEO Kim transformed IDIS into a holding company as a strategy to continuously create social wealth, such as job creation and security, rather than just expanding the scale. Second, as a result of finding “a company that can become the global number one with domestic technology,” KORTEK, BIXOLON, and IDP have successfully formed a business portfolio. Third, unusually, the founders personally visited CEO Kim and proposed M&A, and actually all growing successfully after M&As.

적외선 영상에서의 Point Target 검출을 위한 저역 통과 필터

김영춘,신용달,심태은 永同大學校 1999 硏究論叢 Vol.5 No.1

본 논문에서는 적외선 영상에서의 point target 검출을 위한 적응적 저역 통과 필터를 제안하였다. 제안한 방법은 적외선 영상의 통계적인 특성에 따라 필터의 계수 값을 계산한다. 그래서 균일한 특성을 가지는 영상을 얻는다. 이 영상에 대하여 point target 검출을 위하여 고정된 문턱값을 사용할 수 있다. In this paper, we propose adaptive low pass filter for point target detection in infrared images. This method calculates filter coefficients according to statistical characteristics of infrared images. Thus we obtain the image with uniform characteristics. For this image, we can use the fixed threshold value for point target detection.

慶北地方의 作付體系 確立을 爲한 硏究 : 慶北地方內 地域間 作付體系 現況調査 및 分析 Survey and Analysis on the Present Cropping System among Various Regions

김양춘,徐榮敎,金達雄 慶北大學校 1978 論文集 Vol.25-26 No.-

The objective of this investigation was to obtain the necessary information for the increment of the cultivated land utilization and the establishment of more reasonable multiple cropping system in paddy and upland around Kyungpook Province. For the analysis of the obtained data we used the fixed model employing the arbitrary classification of the regions in sampling. The results of this investigation were summarized as follows: 1. In the acreage per farm household, it was obvious that the farm household in the suburban and truck farming regions has more upland acreage than paddy. On the contrary, there was the exactly reverse trend in the intermediate and fall-behind regions. 2. The old Japonica rice varieties were utilized in the suburban and truck farming regions comparing with the intermediate and fall-behind region using the new Indica-Japonica rice varieties. This tendency in the suburban and truck farming regions was closely associated with the cultivation, especially the harvesting date, of the post-crop after rice. Therefore, it was highly recommandable to develop new high yielding rice variety for the late transplanting in these regions. 3. The rate of the paddy utilization was the highest in the suburban region and was very low in the intermediate and fall-behind region. On the whole regions, the larger paddy owner utilized the lesser in its rate. 4. Barley was cultivated most widely as post-corp after rice in the sampling area. Vegetables in the suburban regions and water melon in Seongju and garlic in the Euiseong were main post-crops in the paddy multiple cropping systems. 5. The rate of the upland utilization was the highest in the suburban regions and was very low in the truck farming region because red pepper and tobacco production region employing only one crop per year. 6. In the double cropping system on the upland, barley and soybean combination was most in the cultivated acreage. The main double cropping system available in the suburban region was fruit vegetables and Chinese cabbage combination. 7. For the increment of the paddy and upland utilization, and of the farm income through the establishment of the reasonable cropping system, it will be desirable to study various possible multiple cropping systems on the experimental basis and the introduction of new crops and varieties may be considered for the incentive of production and return.

김보선,김수영,구달회,방재욱 충남대학교 기초과학연구소 2002 忠南科學硏究誌 Vol.29 No.1

무릇 (Scilla scilloides complex)은 백합과에 속하는 인경 식물로 염색체 조성이 A (x=8)와 B (x=9)의 두가지 게놈의 조합에 의해 다양한 세포유전적 다양성을 보이는 식물이다. 본 연구에서 이들 유형 중 4배체인 ABBB (2n=35)와 BBBB (2n=36+1F+1f), 5배체인 AABBB (2n=43) 등 게놈 유형이 다른 재분화 식물에서 염색체 변이와 함께 A 게놈과 B 게놈의 안정성을 조사한 결과, 염색체 안정성은 ABBB, BBBB 및 AABBB에서 각각 65.9%, 57.0%, 88.3%로 나타나 이질 5배체인 AABBB 유형에서 높은 안정성을 보였으며, BBBB 유형에서 낮게 나타났다. 재분화 식물에서 나타나는 표현형도 세포 유형별로 잎의 개수는 ABBB, BBBB, AABBB에서 각각 1~3, 1~2, 1~2개로 나타났고, 평균 잎의 수는 0.8개, 1.1개, 1.2개로 나타났다. 꽃의 출현은 ABBB, BBBB, AABBB에서 각각 9.6%, 48.6%, 34.9%의 비율로 나타났다. 개화 시기는 AABBB 게놈 재분화 식물체가 8월초에 가장 먼저 개화하였고, ABBB, BBBB 순으로 개화하여 유형별로 차이를 보였다. Plants of scilla scilloides Complex have various cytogenetic types which are composed of two well-differentiated genome, A (x=8) and B (x=9). Chromosome variation in the regenerated plants developed from the types ABBB (2n=35), BBBB (2n=36+1F+lF) and AABBB (2n =43) regenerants were investigated. Considerable variation in chromosome number was found in allotetraploid ABBB and chromosome segments (s) were found. Autosomes were well maintained in allopentaploid AABBB. The elimination of B chromosomes was the common phenomenon in the eutetraploid BBBB regenerants. The mean numbers of leaf were 1.2, 1.1 and 1.1 in ABBB. BBBB and AABBB. respectively. The rate of flowering was 9.6%. 48.6% and 34.9% in ABBB, BBBB and AABBB regenerants.

In order to examine the responses of heart rate and oxygen uptake during the first minutes of bicycle ergometer work with different loads, we measured the heart rate and oxygen uptake on 975, 100, 125, 150, 175, 200 and 225 watts. The results obtained were as follows: 1. Time required for reaching a steady state of heart rate and oxygen uptake was delayed with increasing work loads and it was more significant in case of oxygen uptake. 2. Statistically significant difference was existed in heart rate among different work loads of ergometer cycling except between 125 and 150 watts and between 200 and 225 watts. 3. Statistically significant difference was existed in oxygen uptake among different work loads, especially within 1 minute after onset of ergometer cycling. 4. The changes in the rates of increase of heart rate( HR%) and oxygen uptake( VO₂%) during the work, which were calculated as percentage to the values at 3 minutes after onset of ergometer cycling showed approximately the same pattern regardless of work loads, and the rate of increase was greater in heart rate than in oxygen uptake within 1 minute after onset of ergometer cycling.

This paper presents a method for active noise cancellation utilizing a speaker and microphone pair. In this study, the main focus is on identifying the dynamic characteristics of speaker-amplifier-microphone path. Our study presents a theoretical method to identify the dynamic characteristics of speaker-microphone pairs. The transfer functions of microphone-speaker pair have been estimated utilizing sequential least square(SLS) algorithm. We identified the estimated transfer function has stable poles and zeros in z-plane. This paper also propose an architecture for the noise cancellation to which we applied the estimated transfer function. The details of the proposed architecture, and theoretical simulation and experimental results of the noise cancellation system for three dimension enclosure are presented in the paper.

제약적 최소자승추정을 이용한 미분기반 다중계층 광류 추정

김영춘,신용달,권기구 永同大學校 2001 硏究論叢 Vol.7 No.1

본 논문에서는 광류 제약 방정식(optical flow constraint equation) 및 영상의 공간적인 상관성을 고려하여 제약적 최소자승추정(constrained least square estimation)을 이용한 미분기반 다중계층(multiscale) 광류 추정 방법을 제안하였다. 제안한 방법은 인접한 화소간의 움직임 속도가 유사하다는 가정 하에 다중계층으로 광류를 추정하였다. 또한 본 논문에서는 광류 제약 방정식 및 인접한 화소간의 움직임 속도가 유사하다는 가정에 의하여 발생하는 오차를 줄이기 위한 정제(refinement) 방법도 제안하였다. 제안한 방법이 기존의 방법에 비하여 더욱 정확하게 광류를 추정할 수 있음을 실험을 통하여 확인하였다. In this paper, we propose a gradient-based multiscale optical flow estimation method using the constrained least-square estimation, considering the spatial correlation of the image. The basic assumption of the proposed method is that the neighboring pixels are having a similar velocity. Also we propose a refinement method to decrease the error, reviving optical flow constraint equation and neighboring pixels are having a similar velocity. Experimental results show that the proposed method can more accurately estimate the optical flow than the conventional methods.
