장영택 한국정보시스템학회 2000 情報시스템硏究 Vol.9 No.1

Today a knowledge management systems (KMS) is an enabler for gaining competitive position in the market environments. However, it is just recognized as a conceptual management paradigm not as realistic management philosophy in an organization. A firm just accustomed to deal with tangible assets such as inventory and buildings based on the cumulated experiences. However, the firm often struggle with how to define and apply the knowledge management system into its real business activities such as business strategy and productivity. For example, one of textile company, E-land, in Korea found the way how the firm utilize intelligent assets of its employees to overcome the performance differences among the employees in an organization to increase their ability. Managers in an organization should fully understand and try to figure out the concept of knowledge management systems to implement KMS more efficiently and effectively. Even though lots of previous knowledge management literature proposed several unique knowledge management process models, they have their own terms, process sequences, or different approaches. There are three common knowledge management processes: knowledge creation, knowledge store and search, knowledge sharing process. In this study, a new KM process theoretical framework based on the previous researches is developed. This study will guide to those who will adopt or implement of KMS in the organization in near future.

PC통신 육아상담을 통해 살펴본 육아상담 분야 및 방향에 대한 연구

채영숙,장영택 대한소아청소년과학회 2000 Clinical and Experimental Pediatrics (CEP) Vol.43 No.7

목 적 : 아이를 잘 키우고 싶은 것은 모든 엄마들의 공통된 바램이다. 하지만 올바른 육아상식을 잘 모르기 때문에 무조건 집안 어른이나 주위 사람들의 말만 따라 문제를 해결해 나가는 경우가 많이 있다. 물론 그 중에는 올바르고 현명한 육아방식도 많이 있으나, 많은 엄마들이 잘못된 사실 또한 진리인양 따르고 있는 경향이 있어 젊은 초보 엄마들이 어떤 것을 궁금해하고 어떤 대책을 마련해야 할 것인지 알아보기 위하여 본 연구를 시작하였다.방 법 : 1994년 4월부터 1999년 3월까지 PC통신 하이텔을 통하여 육아 상담한 2,754명의 부모를 대상으로, 해당 아이들의 성별·연령별 분포 및 주된 질문의 분야 분석을 하였으며 각 분야별로 주된 질문의 빈도를 조사하였다. Purpose : Nowadays, concern about the care of one's offspring has been increasing due to increased active participation of women in society and having fewer children than in the past. Therefore, we performed a study to evaluate the major fields of child care counselling and establish effective child care counselling. Methods : We retrospectively analyzed 2,754 cases of child care counselling about sex ratio, distribution of age, major fields of concern and major questions of each field using personal computer communication from April 1994 to March 1999. Results : Sex distribution was usually unknown. The most frequent questions concerned the infantile period, especially less than 6 months of age. Nutrition, digestive system, development and psychology were the major fields of child care counsellng. Conclusion : We conclude that the major period of child care counselling was during the infantile period, and there was a major concern about nutrition, development and psychology. But, more efforts and studies are needed to establish effective child care counselling.

上顎에 發生한 adenomatous ameloblastoma의 症例報告

鄭淳慶,張英澤,柳署潤,崔宣壽,林昌潤 現代醫學社 1968 現代醫學 Vol.9 No.5

The authors have observed a case of adenomatous ameloblastoma occurred in the upper right canine portion of the maxilla in 16 year old girl. 1. The clinical and roentgenographic findings were resembled to the dentigerous cysts. 2. Microscopically, the epithelial islands were revealed ameloblastomatous solid cellular areas and a numbers of duct-like structures distributed throughout the tumor. These structures were more or less circular on cross section and they consisted -0f radially arranged columnar cells, generally in a single layer. The nuclei of these cells were situated toward the basement membrane, the direction of polarization being such that the clear, non nucleated ends of the columnar cells presented inward, toward the cystic space enclosed by the layer of cells. Within this space there was often some eosinophilic homogenous material which appeared to be a product of the columnar cells. Throughout the tumor, foci of calcification were scattered. These foci were not numerous and they tended to be quite small, and they were not resembled to the enamel, dentine and cementum like structures.

열이 있는 3개월 이하의 영아에서 수막염의 예측에 대한 연구

송향순,장영택,김은옥 대한소아감염학회 2009 Pediatric Infection and Vaccine Vol.16 No.1

Purpose : The purpose of this study was to identify useful predictors for diagnosing bacterial meningitis and performing CSF studies in febrile infants three months or younger. Methods : Six hundred and fifty two febrile infants with a rectal temperature ≥38.0℃ presented from January 2003 to April 2008 and were retrospectively studied. The total white blood cell count (WBC), band count, absolute neutrophil count (ANC), quantitative C-reactive protein (CRP) and blood cultures were performed on admission. The clinical variables associated with bacterial meningitis were analyzed. Results : In patients with bacterial meningitis, the clinical variables including CRP (P=0.036), band count (P=0.037), ANC (P=0.036) and age (P=0.001) were significantly different. The area under the receiver-operating characteristic curve was 0.969 for CRP, 0.946 for the band count, 0.765 for the ANC and 0.235 for age. A CRP cutoff point of 8 mg/dL was determined to maximize both the sensitivity and specificity (sensitivity 83%, specificity 95%, likelihood ratio 16.6). A CRP concentration of <7 mg/dL "ruled-out" bacterial meningitis, with a likelihood ratio of 0.17, a posttest probability of <0.1% and negative predictive value 91%. A CRP concentration greater than 9 mg/dL had a much higher likelihood ratio (20.1) than the band count (16.6) and ANC (2.2). Conclusion : The CRP concentration was a useful laboratory test for the differential diagnosis of bacterial meningitis among febrile infants three months of age or younger. A CRP concentration of <7 mg/dL effectively ruled out bacterial meningitis; a value ≥9 mg/dL increased the clinical suspicion of bacterial meningitis and the need for CSF evaluation. 목 적: 3개월 이하의 열이 있는 영아에서 세균성 수막염의 진단에 도움이 되는 유용한 예측인자를 알아보고자 연구를 시작하였다. 방 법: 2003년 1월부터 2008년 4월까지 전주예수병원에 직장 체온으로 38℃ 이상의 발열을 주소로 내원한 3개월 이하 의 영아 652명을 대상으로, 내원 당시 체온, 말초 혈액에서 총 백혈구수, 대호중구수, 절대호중구수, C-반응 단백, 혈액 배양검사를 하였고, 세균성 수막염과 연관있는 인자를 분석하 였다. 결 과: 세균성 수막염과 관련된 인자로는 C-반응 단백, 대호중구수, 절대호중구수, 연령의 P value가 각각 0.036, 0.037, 0.036, 0.001로 모두 통계학적인 의의가 있었다. C- 반응 단백, 대호중구수, 절대호중구수, 연령의 곡선하면적은 각각 0.969, 0.946, 0.765, 0.235이었으며, C-반응 단백의 민감도, 특이도 및 차단점은 각각 83%, 96%, 8 mg/dL, 대호 중구수는 각각 83%, 95%, 2,500/mm3, 절대호중구수는 각각 83%, 62%, 5,100/mm3이었다. C-반응 단백이 7 mg/dL 미만 에서는 우도가 0.17이고, 사후확률은 0.1%, 음성예측도가 91% 이어서 세균성 수막염을 배제할 수 있었으며, C-반응 단백이 9 mg/dL 이상인 경우 우도는 20.1로, 대호중구수의 16.6, 절대호중구수의 2.18, 연령의 0.61보다 높아서, 혈청 C-반응 단백이 세균성 수막염을 예측하는데 가장 유용한 것 으로 판단되었다. 결 론: 3개월 이하의 영아가 발열이 있는 경우 C-반응 단 백, 대호중구수, 절대호중구수가 높은 경우에는 세균성 수막 염과 관련이 더 많았으며, 특히 혈청 C-반응 단백이 가장 유용 한 인자로, 7 mg/dL 미만인 경우는 세균성 수막염을 배제하는 데 도움이 되었고, 9 mg/dL 이상인 경우에는 세균성 수막염 의 강한 예측인자가 되어 뇌척수액 검사를 적극적으로 고려해 야 할 것으로 사료되었다.

Yoo, Sangjin,Jang, Youngtag,Yoon, Seongno 한국경영과학회 2001 經營 科學 Vol.18 No.1

We often feel the necessity to communicate with members involved in a project to remote discuss business activities, needs for the fast file transfer, and check the existence of members to talk with. There are some commercial applications in these problems. However, in addition to those existing functions, this study focuses especially on adding couple of functions such as automatic responding function, in which a sender of a message automatically knows if a receiver checks the message. Its application is that a project leader sends an important message and later on can check at his desk the fact that who have checked their messages. The prototype application, build in this study, will check the correctness of every sub-function, and then the interface of inter-sub-functions, finally the integrity of the entire system, so that important information will not be lost among members of a project in the real world situation.

열이 있는 3개월 이하의 영아에서 세균성 감염의 예측에 대한 연구

전명원,이지영,장영택,Jeon, Myeoung Won,Lee, Ji Young,Jang, Young Taek 대한소아감염학회 2003 Pediatric Infection and Vaccine Vol.10 No.2

목 적 : 3개월 이하의 영아가 열이 있는 경우에 세균성 질환의 가능성이 크고 단순한 바이러스에 의한 질환과 감별이 어려워 여러 가지 검사 및 입원 치료를 하게 되는데, 고위험군과 저위험군을 분류하여 불필요한 검사와 치료를 줄이기 위한 연구들이 진행되었으나 통일된 방법은 없었다. 따라서 저자들은 열이 있는 3개월 이하의 영아들을 대상으로 심각한 질환과의 관련성 및 치료 방향을 살펴보려고 본 연구를 시행하였다. 방 법 : 2001년 1월부터 2002년 12월까지 전주 예수병원에 발열(항문 체온 ${\geq}38.0^{\circ}C$)을 주소로 내원한 3개월 이하의 영아들을 대상으로 내원 당시 검사기록을 기준으로 고위험군과 저위험군을 분류하고 이에 따른 심각한 세균성 질환과의 관련성을 조사하였다. 결 과 : 1) 총 378명의 환아 중 고위험군 216명(57.1%), 저위험군 162명(42.9%)이었고, 고위험군으로 분류된 항목 중에서는 말초 혈액 검사 이상이 100명(26.2%), 소변 검사이상이 99명(26.3%), 뇌척수액 검사 이상이 75명(22.3%)이었다. 2) 심각한 세균성 질환이 105명(27.8%), 심각한 질환이 172명(45.5%) 발생하였다. 이중 요로 감염이 98명(25.2%), 패혈증 10명(2.6%), 세균성 수막염 2명(0.6%), 무균성 수막염 77명(22.8%)이었다. 3) 고위험군 중 76명(35.2%)이 심각한 세균성 질환이었고 저위험군 중 29명(17.9%)이 심각한 세균성 질환이었다. 따라서 위험 예측기준의 민감도는 72.4%, 특이도는 48.7%, 음성 예측치는 82.1%, 양성 예측치는 35.2%이었다. 결 론 : 3개월 이하의 발열이 있는 영아를 고위험군과 저위험군으로 분류하는 것은 심각한 세균성 질환을 예측하는 데 많은 도움이 되나, 본 병원에서는 저위험군에서도 상당수의 심각한 세균성 질환이 발생하였다. 따라서 저위험군이라 하여 외래에서 추적 관찰만 하는 것은 신중하게 결정해야 할 것으로 사료된다. Purpose : This study was to analyze serious bacterial infections in infants younger than three months of age and to review the direction of treatments for these patients. Methods : 378 febrile infants with a rectal temperature ${\geq}38.0^{\circ}C$ visited from Jan. 2001 through Dec. 2002 were retrospectively studied. Infants with the following criteria belonged to the low risk group. WBC $5,000{\sim}15,000/mm^3$, WBC negative in urine stick test and negative for nitirite test, CSF WBC < $10/mm^3$ and negative in CSF gram stain, negative chest X-ray, stool WBC <5/HFP(high power field), and focal infection. If any of the above criteria were not met, they belonged to the high risk group. SBI was defined as a positive culture of urine, blood or CSF. SI was defined as aseptic meningitis or pneumonia including above laboratory tests of SBI. SBI patients were separately compared with two groups, high risk and low risk. Results : Of the 378 infants that were tested 216(57.1%) were in the high risk group and 162(42.9%) in the low risk group. Among 105 SBI(27.8%) and 172 SI(45.5%), there were 98 urinary tract infection(25.2%), 10 bacteremia(2.6%), 2 bacterial meningitis(0.6%), and 77 aseptic meningitis(22.8%). There were 76 SBI(35.2%) from the high risk group and 29 SBI(17.9%) from the low risk group identified. The results of the sensitivity(72.4%), the specificity(48.7%), the negative predictive value(82.1%) and the positive predictive value (35.2%) were calculated. Conclusion : Even though the probability of SBI in the low risk group is insignificant, it should still be considered in febrile infants younger than 3 months of age. I believe the CSF study is necessary because of the moderate high incidence of abnormal finding in our study.
