Societal changes in the late Chosun Dynasty needed a corresponding endorsement in terms of ideological logic. The social thoughts(ideology) dominated by Chu Hsi(朱熹) Neo-Confucianism had attempted to maintain its underlying social system by adhering to the establishment of landlordism as well as the consolidation of caste system. However, the advent of new ideas and things from the West demanded modification or complementation of the world view held by the social thoughts of Chosun Dynasty based on the Chu Hsi Neo-Confucianism. The understanding of the human body derived from the Wests medieval medicine was introduced through the literature like Chuchih Chuncheng(主制群徵) as things and ideas transported from the West span through varied fields. Accounts of Chuchih Chuncheng articulated in detail the anatomical structure of the human body and attached great importance to liver (肝), heart(心) and brain(腦) associated with blood. It is Lee yik(李瀷) that introduced enthusiastically the perspective of Chuchih Chuncheng on the human body. He could take in the discourse of the transferred Western medicine through the mediation of his own epistemology of nature that scrutiny for particulars leads to the universal. Furthermore, the Western medicine that he absorbed and introduced was thought to be a form of methodology by which he could look into the human body as he valued highly self-apprehension(自得) and experience (經驗), and kept open-minded toward other different thoughts. He took notice of the function of organs governing features of human as a living thing, and blood that mediated between the organs. Leeyiks accounts of the human body were fragmented and incoherent and largely based on the conventional Confucian point of view. Nontheless, he viewed the human body as a dynamic being accommodating to the change of time and made room to allow for intrepreting his accounts of the human body in terms of flowing qi(游氣) and blood(血). It is Jeong yak-yong(丁若鏞) that developed further such way of thinking. he reviewed critically the conventional viewpoint of medicine through the Western medicine and attempted to reframe conventional medical knowledge, though to a certain extent. On the other hand, Shin hu-dam(愼後聃) and Ahn cheong-bok(安鼎福) belonging to the rightist group of Seong-ho(星湖)s school held the framework of reification(形化) that allowed for understanding that the circulation of the qi inside the human body is separated from, and thus independent of circulation of the celestial qi, though they did not get fully involved in adopting medical knowledge coming from the Western world. Unfortunately, following suppression on the Western-Studies(西學) swept away the historical occasion that could have provided an opportunity with which to make sense of the human body as an object of the investigation of universal principles(格物) from the perspective of the imported Western medicine.

14살령의 중성화 수컷 개가 혈뇨와 배뇨통으로 내원하였다. 복부초음파 검사에서 편측성 수신증과 요관 벽이 국소적으로 두꺼워진 수뇨관증이 진단되었다. 수술적 탐색으로 좌측 근위 요관에서 요관 유래의 관내 종괴가 확인되었으며, 종괴 절제술이 실시되었다. 요관 종괴는 조직학적 검사를 통해 유두상 이행세포암종으로 진단되었다. 환자는 안정적으로 회복되었으나, 수술 3개월 후 또 다른 종괴가 우측 신장에서 발견되었다. 신장 종괴에 대한 세포학적 검사 결과 간엽세포종양으로 진단되었다. A 14-year-old, castrated male mixed-breed dog weighing 9 kg was presented for hematuria and dysuria. Abdominal ultrasound showed unilateral hydronephrosis and hydroureter with focal thickening of the ureteral wall. Surgical exploration revealed an intraluminal mass arising from the proximal left ureter. Mass resection was performed. Histopathology of the ureteral mass was consistent with a papillary transitional cell carcinoma. The patient recovered well post-operatively, but was diagnosed with another tumor three months later, this time in the right kidney. Fine-needle aspiration cytology of the renal mass revealed an epithelial cell tumor with mesenchymal features.

Authors experienced a unique case of craniopharyngioma which had evolved rapidly after 4 years of total resection for supratentorial meningioma. A 58-year-old woman presented with headache and visual deterioration. Previously, she had undertaken surgical removal of frontal convexity meningioma 4 years ago and had been well without any postoperative sequelae thereafter. Brain magnetic resonance imaging demonstrated a newly developed suprasellar mass. Pertinent operative procedure was performed and histological verification was made as an adamantinomatous craniopharyngioma. She has been showing unremarkable clinical course up to date. Possible pathogenic mechanisms of de novo development of craniopharyngioma are disscussed with review of case.

김성수,김종철,신용철,이선도,이남주,김승수,이춘호,Kim, Seong-Su,Kim, Jong-Cheol,Shin, Yong-Cheol,Lee, Sun-Do,Lee, Nam-Ju,Kim, Seung-Soo,Lee, Chun-Ho 대한핵의학기술학회 2010 핵의학 기술 Vol.14 No.2
FDG PET/CT 검사에서 FDG는 신장 및 요료계를 통하여 배설된다. 이 방사능의 배설을 촉진 시키는 방법을 비교 및 분석하여 각 의료기관의 실정에 맞는 방법을 선택하는데 도움을 주고자 한다. 8개월간 본원에서 PET/CT 검사를 시행한 환자 중 신장에 병적 병변이 없고 기능이 정상인 환자 총 30명을 대상으로 하였다. FDG-PET/CT 기본검사를 마친 환자들을 무작위로 10명씩 다음 세 집단으로 나눠 지연검사를 촬영하였다. (1) 1시간 대기한 집단(Delay group), (2) 수분을 약 700 mL 섭취한 후 1시간 대기한 집단(Hydration group), (3) 이뇨제를 정맥주사하고 30분 대기한 집단(Lasix group). 평가는 육안평가와 정량분석을 하였다. 육안평가는 기본검사와 비교하여 각 집단별 지연검사 영상에서 신장의 방사능 배설을 네 단계로 나누어 비교 및 분석하였다. 정량분석은 기본검사의 표준화섭취계수에서 지연검사의 표준화섭취계수의 감소율을 측정하여 신장 방사능의 배설률로 활용하였다. 육안평가상 Lasix group이 가장 배설이 잘 되었고 그 다음은 Hydration group이었다. Delay group은 효과적인 배설이 이루어지지 않았다. 정량분석 결과 신장방사능 배설률은 Delay group $9.2{\pm}20.7%$, Hydration group $28.1{\pm}22.8%$, Lasix group $29.5{\pm}23.1%$이었다. Delay group과 Hydration group간, Delay group과 Lasix group간의 배설률은 통계적으로 유의한 차이를 보였다. Hydration group과 Lasix group간은 유의한 차이가 없었다. 본 연구에서 이뇨제를 사용하는 것이 신장의 방사능 배설을 촉진시키는데 가장 효과적임을 확인할 수 있었다. 또한 수분을 섭취하는 방법도 비슷한 효과를 보였으며 수분 섭취 없이 지연영상을 얻는 것은 효과가 없음을 확인 하였다. 이상의 방법들을 각 의료기관 실정에 맞게 적용함으로써 영상의 질 향상에 도움을 줄 수 있을 것이다. Purpose: Renal excretion is the main route of FDG clearance in FDG PET/CT scan. Applying optimal method of renal excretion is very important for enhancing image quality and diagnostic accuracy. We evaluated several methods of renal excretion in FDG PET/CT scan. Materials and Methods: Thirty patients with normal renal function were prospectively included. Patients were divided into three group and undergone early and delayed FDG PET/CT scans. (1) Delay group; at 1 hour later of early scan, delayed scan was performed without additional hydration, (2) Hydration group; at 1 hour later of early scan, delayed scan was performed with additional oral hydration (700 mL of water), (3) Lasix group; lasix was administered at the end of early scan and dealyed scan was performed 30 min later. Early and delayed scans were compared to evaluate efficiency of renal excretion. Visual and quantitative analyses were performed by experienced physician and technologist of nuclear medicine. Results: On the visual analysis, renal excretion was the most evident in Lasix group followed by Hydration group. Delay group showed poor renal excretion. On the quantitative analysis, washout rates were $9.2{\pm}20.7%$, $28.1{\pm}22.8%$ and $29.5{\pm}23.1%$ for Delay, Hydration and Lasix groups, respectively. Conclusion: Administration of lasix was the best method for enhancing renal excretion. Delayed scan with hydration was also efficient method, but delayed scan without hydration was not adequate method.
1996년 여름철 남해 표층수의 이상저염수 현상과 영양염류의 분포특성
김성수,고우진,조영조,이필용,전경암,Kim, Seong-Soo,Go, Woo-Jin,Jo, Yeong-Jo,Lee, Pil-Yong,Jeon, Kyeong-Am 한국해양학회 1998 바다 Vol.3 No.3
In August 1996, seawater salinity and nutrient distribution were investigated at surface waters in the South Sea of Korea. The low-salinity (< 20.00 psu) waters were observed in the western and southwestern offshore areas of Cheju Island. Relatively low saline (< 30.0 psu) waters occupied most of the survey areas only except in the eastern part. The observed minimum salinity was lower by 11.78 psu than that of the average between 1963 and 1995. The low saline waters appeared in the upper layer of generally 10-20 m deep, and were obriously distinguished from high-salinity (> 32.00 psu) waters, 30 m deep. The low saline waters may originate from the freshwater discharge of vast amount of from Yangtze River during the heavy rainfall season in China. Phosphate concentrations in the surface waters were relatively low and were less variable than those of nitrate and silicate. The maximum concentrations of nitrate and silicate occured in the western and southwestern offshore areas of Cheju Island, where the salinities were the lowest. The concentrations of nitrate and silicate were inversely correlated with salinity, whereas that of phosphate showed a considerable scatter and non-conservative behaviours. This indicates extensive desorption reactions of suspended materials releasing phosphate. 1996년 8월 1일부터 10일까지 남해 해양조사에서 얻어진 자료를 이용하여 우리나라 남해 표층의 저염화현상과 표층수 중 영양염류의 분포특성에 대해 고찰하였다. 제주도 서쪽에 위치한 313선의 05점과 제주도 남쪽에 위치한 314선의 09점에서 20.00 psu 이하의 저염수가 출현하고 있으며, 이 저염수의 핵을 중심으로 30.00 psu 이하의 저염수가 남해 동부해역을 제외한 제주도 주변 대부분의 해역들에 나타나고 있다. 이러한 저염수의 최저염분 농도는 과거 30년 동안의 평균값보다 11.78 psu 낮은 값으로서 이는 양자강 유역에서 6월과 7월에 평년보다 훨씬 많은 강수량에 의해 막대한 양의 담수가 유출되었기 때문이라고 생각된다. 또한, 이러한 저염수는 대체적으로 수심 10~20 m 상부층에 존재하고 있어서 중 저층수와는 확실히 구분되고 있다. 표층수 중 영양염류는 인산인의 경우 농도가 비교적 낮고, 해역별 차이도 매우 작았다. 그러나, 질산질소와 규산규소는 저염수가 분포하고 있는 제주도 서쪽 및 남서쪽 해역에서 비교적 높은 농도를 보이며, 특히 염분농도가 가장 낮은 정점에서 농도가 가장 높았다. 질산질소와 규산규소의 경우 보존성 성분인 염분과 역의 상관성을 보이는데, 이는 양자강 유출수와 같이 영양염류 농도가 풍부한 물이 제주도 서쪽 해역으로 이동되어 왔음을 의미한다. 그라나, 인산인이 다른 영양염류 성분과는 달리 염분의 큰 변동에도 불구하고 농도 변화가 거의 일정한 것은 해수중의 물질순환과정이 질산질소 및 규산규소와는 다름을 의미한다.

Purpose: Heat pressed ceramics, used for all ceramic restorations, have the additional advantage of being technically less change through using of the lost-wax technique. Conceptually, combining the ceramic with the clinically proven reinforcing ability of a metal framework would be advantageous; however, cause of mismatching of fusion between ceramics and metal frameworks which from differences of casting temperature and coefficient of thermal expansion, pressed ceramics could not be used with a metal framework. The purpose of this study was to compare shear bond strength of press-to metal ceramic to porcelain fused non precious metal and feldspatic porcelain fused non precious metal. Methods: The 30 metal specimens were casted in a porcelain fused non precious metal nickel-chromium alloy. They were divided into 3 groups by surface treatment and applied ceramic: $125{\mu}m$ aluminium oxide sandblasting and veneered feldspatic porcelain (group FP), $125{\mu}m$ aluminium oxide sandblasting and had press-to-metal ceramic applied (group PC), porcelain bonder (gold bonder) fused on surface of metal specimens and had press-to-metal ceramic applied (group PCG). In each group 10 metal specimens were used. The press-to-metal ceramic applied 20 specimens had ash-free wax pattern applied, the metal-wax complexes invested, and were pressed with heat press ceramic. All specimens were subjected to shear bond strength test at a crosshead speed of 1.0 mm/min. Results: The results of measured in Mean SD and data were analyzed by one-way AVOVA (p= .05) and Tukey HSD test (p= .05).: group FP $16.090{\pm}1.841$ MPa, group PC $12.620{\pm}1.8256$ MPa, group PCG $10.920{\pm}0.9283$, significant differences between all groups (p < .05). Significant differences were found in each between group FP and group PC, group FP and group PCG (p < .05). Conclusion: The shear bond strength of press-to-metal ceramic to porcelain fused non precious metal was described higher in unused gold bonder group than used gold bonder groups.
