Clinical observations were made on 457 cases of diabetes mellitus who were admitted to the National Medical Center during recent 10 yrs, from January 1966 to December 1975 and the results were as following; 1) The incidence of diabetes among in-patient to the medical ward was 2.9%, showing 2.2 versus 1 in male female ratio and the most prevalent age group was in fifth decade of age in both sex. 2) Non obese diabetes was most common form (72. 1%) and obese diabetes, jubenile form, brittle diabetes in order of frequency. 3) Common subjective complaints on admission were polydipsia (42.8%), numbness and paresthesia (36.8%) polyuria (36.8%) polyuria (31.7%), weight loss(15.8%), and polyphagia (14.2%). 4) As to the common complications, there were neuropathy in 31.0%, hypertension and arteriosclerosis in 19.0%, retinopathy in 11.2%, renopathy in 10.7%, Pulm. Tbc. in 9.6% of the cases. 5) Fasting blood sugar level on admission was 200-300 mg% in 40.3%, 150-200 mg% in 28%, 300-40 mg% in 9.6% and over 500 mg% was 2.6% of total cases. 6) Alkaline phosphatase abnormality was most common findings(27%) in diabetic patients who performed-the chemical liver function tests. 7) Diabetes were well controlled in 291 cases (64%) during hospitalization and insulin requirement was 16-40 unit (N. P. H.) in most cases (80.2%). 8) There were 9 cases of diabetic coma, whose mean blood sugar level were 609.6 mg% and 4 cases expired.

This study was carried out for the quantitative analysis about the counts and the diameters of hepatic erythropoietic cell nuclei in 51 cases of human embryonic and fetal livers from 5 weeks to 40 weeks of gestation under a light microscope. The purposes of this study were to obtain informations about the initiation time of hepatic hemopoiesis, and the stages of activity and the distribution of nuclear diameters of hepatic erythropoietic cells in human embryos and fetuses. The results obtained were as follows. 1. Hepatic erythropoiesis began in 6 weeks of gestation, and many proerythroblasts and undifferentiated cells more than 7㎛ in nuclear diameter appeared in primitive hepatic cords. Megakaryocytes appeared around central veins in the 7-week embryo and a few granulocytes were seen in hepatic cords and in mesenchymal tissue around large vessels in the 8-week embryo. 2. Hepatic erythropoietic activity was rapidly increasing at the embryonic period from 6 weeks to 10 weeks to gestation, and many erythroblasts were observed in primitive hepatic cords from 7 weeks to 8 weeks of gestation. 3. Hepatic erythropoietic activity was maintained at the highest level from 10 weeks to 21 weeks of gestation, and various hepatic erythropoietic cells showed between 3 and 8㎛ in nuclear diameters. 4. The gestation period from 22 weeks to 40 weeks of gestation was the last period in hepatic erythropoiesis and in that period erythropoictic activity began to decrease definitely. With age, immature hepatic erythropoietic cells became to disappear and only mature erythroblasts were seen. Erythropoietic activity decreased rapidly from 33 week to 40 weeks of gestation.

한국인 소녀의 신체발육에 관한 체질인류학적 연구

윤경준,김동창 중앙대학교 의과대학 의과학연구소 1985 中央醫大誌 Vol.10 No.4

Anthropometry on three items(stature, head length, head breadth) was carried out to 3,074 Korean girls of an age group of 12 to 15 years. In addition to them, the head length breadth index was calculated according to each age group. The results obtained are as follows: 1. The average stature showed 148.94㎝ in 12 years age group, 152.21㎝ in 13 years age group, 153.57㎝ in 14 years age group and 157.45㎝ in 15 years age group respectively. The growth pattern of stature showed remarkably high values ranging from 14 to 15 years age group. 2. The average head length showed 16.83㎝ in 12 years age group, 16.89㎝ in 13 years age group, 16.99㎝ in 14 years age group and 17.05㎝ in 15 years age group respectively. 3. The average head breadth showed 14.83㎝ in 12 years age group, 14.90㎝ in 13 years age group, 14.93㎝ in 14 years age group and 15.06㎝ in 15 years age group respectively. 4. The average head length breadth index showed 88.24 in 12 years age group, 88.31 in 13 years age group, 87.98 in 14 years age group and 88.51 in 15 years age group respectively. Therefore, it was found that all of the indices obtained in this belonged to hyperbrachycephaly.

DEA를 통한 보건소의 효율성측정

윤경준 한국정책학회 1996 韓國政策學會報 Vol.5 No.1

공공부문의 효율성향상은 항상 어려운 과제로 인식되어 왔고, 이러한 어려움의 주된 요인 중 하나로 효율성측정의 곤란성이 지적되어 왔다. 이러한 곤란성은 대개의 공공조직이 금액으로 환산하기 어려운 복수의 서비스를 산출하고 있고, 따라서 상이한 단위로 측정되고 있는 산출요소들을 합산한다는 것이 상당히 어렵기 때문이다. 많은 측정방법들이 활용되고 있으나 제각기 일정한 한계를 내재하고 있다. Charnes, Cooper and Rhodes에 의해 고안된 DEA는 복수의 투입과 산출요소들을 임의적 가중치를 사용하지 않고도 모형 속에 포함시킬 수 있으며, 다른 측정방법들이 주지 못하는 유용한 정보를 제공해 줄 수 있다는 점에서 공공부문의 효율성측정을 위한 방법으로 유용하다. 이러한 전제하에 이 연구에서는 DEA에 대한 이론적 고찰과 함께, DEA를 통한 대도시 보건소의 효율성측정을 시도하였다. 보건소에 대한 DEA측정결과는 상대적 효율성점수, 준거집단, 비효율 부문별 비효율의 정도와 개선방향, 그리고 보건소별 효율성 차이에 대한 설명과 관련하여 모두 네 가지 차원에서 논의되었으며, 이러한 각각의 차원에서 보건소의 효율성향상을 위한 정보를 도출할 수 있었다. 끝으로 DEA가 그 측정방법상의 특성에 따라 공공부문의 효율성측정을 위한 일반적 적용가능성을 가지고 있음에도 불구하고 그 나름대로 가지고 있는 여러 가지 한계를 지적하였다.

Development of a 3-dimensional Dosimetry System for Leksell Gamma Knife Perfexion

윤경준,곽정원,이대헐,조병철,이상욱,안승도 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.67 No.1

The purpose of our study is to develop a new, 3-dimensional dosimetry system to verify the accuracy of dose deliveries in Leksell Gamma Knife Perfexion (LGKP) (Elekta, Norcross, GA, USA). The instrument consists of a moving head phantom, an embedded thin active layer and a CCD camera system and was designed to be mounted to LGKP. As an active material concentrically located in the hemispheric head phantom, we choose Gafchromic EBT3 films and Gd2O2S:Tb phosphor sheets for dosimetric measurements. Also, to compensate for the lack of backscatter, we located a 1-cm-thick poly methyl methacrylate (PMMA) plate downstream of the active layer. The PMMA plate was transparent to scintillation light to reach the CCD with 1200 × 1200 pixels and a 5.2 μm pitch. With this system, 300 images with a 0.2-mm slice gap were acquired under each of three collimator setups, i.e. 4-mm, 8-mm, and 16-mm, respectively. The 2D projected images taken by the CCD camera were compared with the dose distributions measured by the EBT3 films under the same conditions. All 2D distributions were normalized to the maximum values derived by fitting peaks for each collimator setup. The differences in the full widths at half maximum (FWHM) of 2D profiles between CCD images and film doses were measured to be less than 0.3-mm. The scanning task for all peak regions took less than three minutes with the new instrument. So it can be utilized as a QA tool for the Gamma knife radiosurgery system instead of film dosimetry, the use of which requires much more time and many more resources.

공공부문 효율성 측정을 위한 DEA의 활용:평가와 제언

윤경준 고려대학교 정부학연구소 2003 정부학연구 Vol.9 No.2

This article reviewed several empirical DEA studies in the academic field of public administration in Korea. Defects of the studies reviewed in this article could be categorized in four folds- relying on theoretical and a priori variable selections process, lack of efforts to demonstrate and utilize the major informations extractable from DEA, running unsuitable post-DEA analysis, and lack of attention to improved methods to surmount drawbacks of DEA. Some proposals for better use of DEA have been suggested concerning the validity of DEA model, the practical use of reference groups, the inclusion of longitudinal point of view, and the proper post-DEA analysis methods. 이 논문에서는 국내 행정학 분야에서 DEA를 활용한 실증연구들을 평가하고 문제점을 지적하는 한편 개선방안을 제시하였다. 2003년 10월까지 주요 행정학 분야 학술지에 게재된 DEA 연구들을 평가한 결과 투입산출 요소 선정에 있어 지나치게 이론적·선험적 방법에 의존하고 있다는 점, DEA가 제공하는 주요 효율성 정보가 제대로 제시 및 활용되지 못하고 있다는 점, 효율성 점수를 활용한 사후분석이 다소 부주의하게 이루어지고 있다는 점, 그리고 DEA가 지니는 방법론적 한계를 완화하기 위한 최근의 방안들이 활용되지 않고 있다는 점 등이 문제로 지적되었다. 평가결과가 제공하는 시사점을 바탕으로 모형의 타당성과 판별력 제고 측면, DEA 결과에 따른 준거집단 활용 측면, 시계열적 관점의 포함 측면, DEA 후속분석의 적절성 제고 측면 등에서 개선방안 내지 검토사항들을 제시하였다.
