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 rating 0.4% of the total. 10) Psychomotor changes (apathetic, miserable, inert, withdrawn, or anorexic) rated 7.0% of the young children only, and 5.7% of the whole examined. 11) Prevalence rate of diarrhea precipitating dehydration and such other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.

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.

A diagnosis method to inspect deterioration in overhead ACSR conductors is discussed in this paper. Corrosion would be occurred by various and complex factors such as atmospheric indices, installation environment and metallic configuration, but must of corrosions are mainly due to atmospheric corrosion, galvanic corrosion and crevice corrosion. Such corrosion in ACSR would lead to be zinc loss of galvanized steel strand and reduction of cross section area of aluminum strand and it may be mechanical strength of power conductor in service to reduce. Global corrosion can be treated as average corrosion occurring on the conductor and it would appear to any material variations by the elapsed years of the conductor in the atmosphere. Therefore, as estimating the loss rate of tensile strength of aged conductor corresponding to the elapsed years, it would be possible to quantify global corrosion indirectly to a prediction function. Through such results, loss degree for ACSR 97[mm2] is classified to 4 ranges. i.e., no loss, possible loss, partial loss and sever loss. Both local and global corrosion could not be detected by visual inspection, but we proposed a corrosion detector system using a solenoid eddy current sensor in order to inspect such corrosion for old conductor. Corrosion detecting system is constituted to a corrosion detector and a ground station controller. Corrosion detector consists of sensor coil and sensing head, signal processing unit, data communication system, motor driver and controller, u-processors and power supply. After considering operation and manipulation in the field, motor, battery and wheels were selected and designed in order to reduce the weight of corrosion detector. Programs for u-processors, measurement program operated in a PC were also developed. Before testing the corrosion detector in the field, several experiments were carried out in the laboratory for artificial corroded samples. Sensor performance, mechanical tests such running ability and weight, and RF data transmission as well as measurement program were examined. After testing a simple corrosion detector system in the laboratory, several filed tests were carried out in practice transmission lines installed in domestic area. Finally, the suggested corrosion detecting system shows an effectiveness to detect local corrosion in acted conductor in practice.

The purpose of this study was to suggest the developmental ideas for graduate school in Yougin University. For the methods of this study, the researches in administration of graduate students, personal researches in socialization of graduate school, and evaluation materials for graduate school were utilized. Additionally, the questionnaire survey about graduate students leas administered and analyzed and the ideas constructed from staff meeting for the development of graduate school were applied in preparing developmental plan. The results of this study are summarized as follow: 1. 1-2 years preparation - offers annual credits upto 30 - jop marketing upto 70% - advisor and student ratio 1 : 7 - professors' doctoral degree possession upto 90% - graduate school professors' research achievement upto 2 articles annually - research space per student upto 10m/2 3-4 years preparation - offers annual credits unto 33 - advisor and student ratio 1:4 - professors' doctoral degree possession upto 95% - graduate school professors' research achievement upto 2.5 articles annually 2. The educational goals of graduate school should be recognized among graduate students and the professionality of faculty members should be emphasized to teach graduate students in their relative major areas. The evaluation procedures for graduate class lecture and class administration in graduate school. 3. To reach unto lecture system, field study should be expanded and inter-credit system between Yongin universities and foreign university should be contracted. 4. Expanding of graduate school facilities should be cranked in to provine the optimal environment for the student education and schoolship should be widely offered to the students. 5. To promote the administrational development, the staff system should be changed from reverse hierarchy system to hierarchy system. Therfore, the number in lower administrational staffs should be larger than upper positions. And, the classification of authorities into department could be suggested for the efficacy of administration and management of graduate shool. 6. The specialization in each major should be emphasized. In the calc of graduate stool of physical education, the administration live should be unified in one body system. In the case of graduate school of business, one department of administration could be classified into management of sightseeing and tourism, management of distribution, tax accounting, then the specialty of the department can be forced. In the case of graduate school of art, the specialty can be forced by teaching highly performed skills and needed to switch from special graduate school to professional graduate school. The graduate school of health and school of environmental science are recommended to be built after all. Therefore, the connection between undergraduate and graduate curiculum can be established and open 2-3 more majors in the graduate school.
