Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.

최홍봉,윤성민 한국경제지리학회 2004 한국경제지리학회지 Vol.7 No.1

이 연구는 수도권에 위치한 벤처기업과 지방에 위치한 벤처기업 사이에 어떠한 차이가 존재하는가를 분석하는데 목적이 있다. 중소기업청의 '벤처기업 경영실태조사' 원자료를 이용하여 실증분석한 결과는 다음과 같다. 첫째, 수도권에서는 소프트웨어·정보통신 등 첨단 서비스 업종이나 첨단 제조업의 비중이 상대적으로 큼에 비해 지방에는 전통 제조업에 속하는 벤처기업의 비중이 상대적으로 컸다. 둘째, 수도권 벤처기업의 네트워크적 특성은 상대적으로 기업간 기술협력 활동이 활발하고 마케팅 분야에서의 기업간 전략적 제휴에 관심이 많은 반면, 지방의 벤처기업의 경우에는 대학과의 기술협력활동이 활발하고 기술개발활동에 전략적 제휴의 목표가 주어져 있음이 나타났다. 셋째, 수도권에 위치한 벤처기업들이 기술개발능력이 지방의 벤처기업들 보다 더 뛰어났으며 경영성과도 좋은 것으로 나타났다. In this paper, we tries to investigate whether there are some differences of the characteristics between venture business in the metropolitan area and in the local area. We set up some hypotheses on the regional characteristics of venture business and test those using the raw data of Small and Medium Business Administration (SMBA) survey on the management of venture business. Our main findings are as follows: First, we analyze the industrial composition of ventures by region and find that in the metropolitan area high-technology venture business which is belong to software, or information, or communication industries is given much weight. But in the provinces, ventures belong to traditional manufacturing industries is given much weight. Second, we compared the characteristics of business network by region and find that the ventures in the metropolitan area are active in technical cooperation among companies and want strategic tie-ups in marketing field, whereas the ventures in the provinces are active in technical cooperation with university and want strategic tie-ups in technical development field. Third, ventures in the metropolitan area are more excellent in technical development and management than ventures in the provinces.

학생들의 인지발달을 촉진시켜 학습효과를 높이려고 개발된 CASE 프로그램의 효과를 조사했다. 중학교 1학년(841명) 학생들이 연구에 참가하였으며, 같은 분량의 시간동안 실험반에서는 교육과정에 따른 과학 교과 수업과 '생각하는 과학' 활동을 병행하였고, 통제반에서는 과학교과 수업만을 수행하였다. 연구 초기에 논리적 사고력 검사(SRT II)를 이용하여 집단의 동질성을 비교하고, 2년 동안 실험반에 CASE프로그램을 처치한 후 이질동형겸사도구인 SRT VII을 이용하여 처치별, 성별, 인지수준별 인지가속에 대한 효과를 조사했다. CASE 프로그램에 의한 중학생들의 인지발달 가속효과는 중간검사에서는 보이지 않았으나, 사후검사에서 상당히 큰 것으로 확인되었다. 성별에 따라 CASE 프로그램의 효과를 비교한 결과 남??여 중학생들 모두에게 유의미한 인지가속이 이루어진 것으로 나타났다. 남학생들 보다 여학생들의 인지수준이 더 발달된 것으로 밝혀졌으며, 처치와 성별간 상호작용 효과는 나타나지 않았다. 학생들의 사전 인지수준에 따라 CASE 프로그램의 효과를 분석한 결과, 모든 인지수준에서 처치효과가 뚜렷하게 있었으나 특별한 경향성은 나타나지 않았다. 특히 초기 구체적 조작기(ES=1.1.)와 전조작기(ES=1.07), 그리고 구체적조작 후기(ES=1.01) 학생들에게 상당히 큰 효과가 있었다. 이상과 같은 CASE 프로그램의 성공적인 결과는 현행 우리나라 과학교육과정 개정과 교수방법 개선에 시사하는 바가 많다. In an attempt to accelerate the development of formal reasoning ability of students, 'Thinking Science' activities developed by the Cognitive Acceleration through Science Education(CASE) project were implemented to 841 students in 7th grade aged 12+ in six middle schools over a period of two years. Homogeneity between the CASE group and control group was tested with SRT Ⅱ, while the improvement of formal reasoning ability of the students was tested with SRT Ⅶ. The results were analyzed by treatment, gender, and cognitive levels of the students. Statistically significant gains were shown in the CASE group compared with those in the control group. Cognitive level of girls in the CASE group significantly increased as compared with the control group, while there was moderate effect in boys. These results implied that the thinking science activities were effective in cognitive acceleration of girls aged 12+. It was shown that much more CASE students in pre or concrete operational level shifted. to formal operational level as compared with the control group while there were significant effects in all levels (ES=0.31∼1.10) without showing any tendency.

Under the pressure to open the service market as proposed by World Trade Organization, we can easily expect our educational systems for allied health professions will experience a lot of changes in near future. Accordingly, we compared our current educational systems for allied health professions with the foreign ones and mapped out some strategies predicting the forthcoming enormous changes. Major investigations and analysis are summed up as follows, The educational programs for allied health professions which was started in 1963 in Korea are stilled remained as 2 to 3 school years, while the systems in advanced countries have already been changed or been changing from 2 year to 4 year college levels. We can hardly find the uniform educational system or school years for the allied health professions in the world except for Korea. Fortunately, university level four-year programs for the profession was established in 1979 in Won-joo for the first time in Korea. However, there are still only few four-year programs in this country. To meet the rapidly changing needs we have faced in the health areas we should supply appropriate health personnel through various efforts. Now we would like to suggest followings, <Educational goals for the allied health professions> 1) reconfirming characteristics for the educational goals of health professions 2) extending school years for the allied health professions 3) strengthening clinical training and internship 4) expanding opportunities for the continuing education through lifelong education 5) upgrading from old-fashioned technologies to advanced technologies 6) cultivating competencies of health professionals for the global competition <Suggestions for the Development of Allied Health Professions> 1) reforming the school years of educational programs for the allied health professions to meet the global standards 2) expanding the role of junior college programs for the allied health professions through the development of intensive courses in the professions. 3) diversifying and specializing the allied health professions mainly through 4 year B.S. degree programs.

In a previous study, we developed a new food additive as an egg yolk antibody (IgY) against carbohydrate digestion enzymes for the regulation of blood glucose level and weight control. The IgY delayed and decreased the increment of blood glucose level after administration of sucrose in human being by 30% in 20∼30 min. We also developed a lipase inhibitor as a water extract of two kinds of herb, Platycodon grandiflorum and Solanum melongena. Twenty three volunteers were subjected to the intake of the egg yolk IgY plus the herbal extracts for 50 days. In average, the treated subjects appeared to lose 1.96 ㎏ of body weight and 3.4 ㎏ of body fat mass during the treated period. Furthermore, Panniculus adiposus and breech size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of egg yolk IgY and natural herbal extract improve the obesity by the decrement of body weight and body fat mass.
