N/A To evaluate availability of cerebral radionuclide imaging for diagnosis of brain death, we examined 25 patients with a suspected clinical diagnosis of brain death. 8 patients were studied by Tc-99m-DTPA and 15 patients were by Tc-99m-HMPAO (Hexamethyl propyleneamine oxime). Seven patients with Tc-99M-DTPA studies revealed absence of cerebral blood flow and sagittal sinus activity. All of 15 patients with Tc-99m-HMPAO studies revealed complete absence of cerebral perfusion. The results of the cerebral radionuclide studies of brain death correlated with other clinical conditions, such as intracranial pressure(ICP), EEG, transcranial doppler sono- graphy(TCDS), and neurologic examination. The ICP of 8 patients, who are confirmed by brain death with Tc-99m-HMPAO study are elevated in all cases. In conclusion, cerebral radionuclide imaging for diagnosis of brain death is available. Tc-99m-HMPAO imaging is unequivocal, easily interpreted, well reflect the physiologic state of increased ICP, and provides adequate assessment of posterior fossa activity. In addition, the SPECT imaging with Tc-99m-HMPAO produces more accurate results due to it's superiority of image contrast and proper localization of radiopharmaceutical distribution than conventional planar imaging.

N/A It is well known that hepatobiliary agent are taken up by metastatic hepatocellular carcinoma(HCC) as well as primary HCC. But the reported cases of the extrahepatic metastasis of HCC diagnosed by hepatobiliary scintigraphy are for the most part hematogenous ones. The relation of the uptake pattern of hepatobiliary agent in the primary and metastatic HCC is also still remains unknown. So we undertook this study to evaluate the relation of the hepatobiliary scintigraphic patterns of primary and metastatic HCC with different metastiatic routes. Nine patients with primary HCC and twelve cases of metastaic HCC including four lung metastases, one bone metastasis, one right atrial metastasis, one peritoneal wall metastasis, and five lymph node metastases were studied with Tc-99m-DISIDA scintigraphy. The images were taken on 10, 30 minutes, 1, 2, 4-6 hours. The overall detection rates of hematogenous metastases(lung and bone) is 60%(3 of 5), direct metastasis(right atrium and peritoneal wall), 100%(2 of 2) and lymphatic metastases, 0%(0 of 5). In four of five metastatic cases demonstrated with hepatobiliary scintigraphy, biliary agent is also taken up by primary HCC lesions. And the appearing time of the radioactivity in the direct metastatic HCC lesion is same as that of primary HCC and in the cases of hematogenous metastasis, earlier than that of primary HCC. Hepatobiliary scintigraphy is more useful in the diagnosis of the metastatic HCC than primary HCC, in the cases of hematogenous and direct metastasis.

A study was performed to evaluate the atrophic changes of the central nerve system after chemotheraphy in the patients with acute leukemia. the computed tomographic findings and medical records 20 proven acute leukemia patients under 35 years-old who developed various CNS symptoms and signs during and/or after 2 coures of chemotheraphy were reviewed. The results were as follows : 1. Age distribution was 14 to 35 years (mean was 26 years) Male was 15. 2. Presenting clinical symptoms and signs were headache (16/20) nausea and vomiting (11/20) and loss of con-sciousness(5/20) 3. Brain atroply was noted in 16 patients including cortical and subcortical atrophy 15 cases and succortical atrophy 1 case. 4. Two cases of hemorrhage one each of intracranial hematoma and chronic subdural hematoma were found in addition to brain artophy. This showed that chemotherapeutic agents cause brain atrophy in a considerable number of the patients with symptomatic acute leukemia.

본 연구는 조직문화에 대한 선행연구들을 기반으로 한국 기초자치단체에 적합한 조직문화 유형에 대한 탐색적인 논의를 제시하는데 목적이 있다. 오늘날의 정부는 무한경쟁 체계에서 생존을 위한 성과중심의 조직운영이 요구되고 있다. 이는 현대사회가 직면한 사회경제적 변화에 대한 정부의 적극적 대응이며 당면한 문제들에 대한 보다 효율적이고 생산적인 대응을 가능케 한다. 성과지향적 정부 운영은 기존의 관료제적 연공서열 조직문화를 지양하고 성과중심의 조직문화를 구축해 공무원의 동기유발과 행동의 변화유인을 추구한다. 하지만 한국 기초자치단체의 현실에 어떠한 조직문화 유형이 적합할 것인지에 대해서는 보다 실증적 검토가 요구된다. 이러한 배경 하에서 본 연구는 조직문화에 대한 경쟁가치모형을 토대로 서울시 양천구를 대상으로 어떠한 조직문화 유형이 조직효과성 향상에 영향을 미치는지를 논의하고, 이를 토대로 한국 기초자치단체에 적합한 조직문화 유형을 탐색한다. 분석결과 개발문화와 합의문화가 조직효과성에 긍정적 영향을 미치는 반면 위계문화와 합리문화는 유의미한 영향을 미치지 않는 것으로 나타났다. 이를 통해 한국의 기초자치단체에서는 무엇보다 조직의 도전이나 진취성 추구, 그리고 조직 내 합의가 조직효과성 제고에 중요한 요인이라는 점을 확인할 수 있다. This study aims to explore organizational culture which is appropriate to Korea’s local governments with a case of Yangcheon-Gu of Seoul based on a wide range of literature review. Organizational performance has been regarded as one of the most important factors in operating both private and public organizations, so the government has to be more efficient, productive and responsive to people’s needs. This means organizational culture in the public sector has been changed to performance-based culture. To testify this, it has to be empirically studied which type of organization culture is more appropriate to Korea’s local governments. Based on this idea, this article analyzes, with a case of Yangcheon-Gu of Seoul, which type of organization culture has a positive effect on organizational effectiveness in Korea’s local governments, by a competing values model. The analysis reveals that development culture and consensual culture has a positive effect on organizational effectiveness whereas hierarchical culture and rational culture does not. This might show that challenge, progressiveness, and organizational agreement have significant effects on Korea’s local governments.

Background : Several methods have been developed to measurcs in thickness, including the use of the radiography, micromcter screw gauge, Harpendens ealipir, and ultrasound, but there are no reports to measure skin thickness of Koreans using computed ta nography. Objective : We measured seen thickness on the CT films retnisp ctively. This study was to investigate variations of skin thickness by age, gender, and different ites. Methods : Skin thickness was measured on the CT films of 6 patients, including 357 males and 205 females who had undergone brain, chest, and abdomna CT in our hospital. Patients with endocrinologic, malignan, or collagen disease and those on ar ltimetabolite or steroid therapy were excluded. Comparisons of histometric and computed tomorahic methods were made in 5 skin tumors and 1 localized lipodystrophy. Results : 1. The measurements of tbe skin thickness(mean) in examined ites varied from 0.84 to 3.07 milimeters the posterior part at the level of the chestaortic and level was the thickest and the anterior part at the level of the forehead(frontal sinus level) wate thinnest. 2, Skin thickness in males was generally thicker than in females the anterior and lateral part at the level of the forehead(P<0.0001), the posterior part at type level of the bladder(P<0.01), and the posterior partat the level of the chest and forehead (P<002) were thicker in males than in females. 3. In each gender, the thickness of the skin increased with age of 40 or 60, and then decreased with age at every level. 4. Skin on posterior parts of the body was thicker than on othrmrts. 5. Unlike other levels, skin was thicker on the lateral parts temi on the anterior parts at the levels of the forehead and bladder. 6. The measured skin thickness is about 7% greater in formalin fixed tissues than on CT films. Conclusion : Computed tonxigraphic measurement of the skin hickness is a reliable method in the aquisition of normal values and their individual variations duringg cutaneous aging. Moreover, this method is useful in evaluiating skin tumors and monitoring the esponse to therapy of inflammatory conditions. (Kor J Dermatol 1995;33(2): 303-313)

Estimation of liver size is essential in the diagnosis of liver disease, Many approaches have been attempted in evaluation of liver size such as the measurement of length, area and volume. Among these, area and volume measurements are accurate but complicated, so we commonly use formerly introduced various linear measurements, but in scintigraphy one must calculate the actual liver size using rate of reduction, which is time consuming. Because of these reasons, we carried out present study to represent liver size by means of a simple liver measurement like we express the cardiac size by cardiothoracic ratio. Our cases consisted of 100 clinically normal subjects as the normal group and 50 patients suffering from liver disease and diagnosed to have hepatomegaly on abdominal palpation and scintigram at Dept. of Radiology of St. Mary's Hospital, Catholic Medical College during the period of 8 Months from Jan. 1980. We Measured the liver size using 4 linear diameters(Fig. 1). And as the reference measurement, the distance from the right margin of the liver to the left margin of the spleen was measured. We called this $quot;abdominal transverse diameter(ATD)$quot;. The results were as follows; 1) The smallest value was recorded in the midline vertical diameter(MVD). It was 4.2±0.4cm in normal group and 5.0±0.6cm in the hepatomegaly group. 2) The diameter using other methods ranged from 5.6 to 7.2cm in the normal group and from 6.3 to 7.5cm in the hepatomegaly group. 3) There was significant difference in the ratio of each diameter to ATD between the normal and hepatomegaly group(〈0.0l). We called this $quot;hepato-abdominal ratio$quot;. 4) The $quot;hepato-abdominal ratio$quot; using MVD is 0.43±0.06 in the normal group and 0.53±0.07 in the hepatomegaly group. The $quot;hepato-abdominal ratio$quot; of MVD was most significantly different between normal and hepatomegaly group. 5) The tolerance limits(99%) of $quot;hepato-abdominal ratio$quot; using MVD is from 0.41 to 0.45 in the normal group and from 0.51 to 0.55 in the hepatomegaly group. Therefore, by reasons
