Purpose: The prognosis for Borrmann type 4 gastric cancer is dismal although therapies for gastric cancer have been developed. We investigated the outcomes for Borrmann type 4 gastric cancers compared to those for other types of cancer. Materials and Methods: Between 1993 and 2000, 777 patients with advanced gastric cancer underwent surgical resection at the Department of Surgery, Korea University Hospital. The clinicopathologic features of 138 patients with Borrmann type 4 carcinomas of the stomach were retrospectively reviewed from the database of gastric cancer. The results were compared with those of 639 patients with other types of gastric carcinomas. Results: Patients with Borrmann type 4 carcinomas tended to be younger and to have larger tumors. The location, the depth of invasion, lymph node metastasis, and distant metastasis were significantly different between the two groups. Patients with Borrmann type 4 carcinomas had a more advanced stage than patients with other types of carcinomas. The analysis of the treatment factors revealed that total gastrectomies were more frequent in the group with Borrmann type 4 carcinomas and that the curative resection rate of patients with Borrmann type 4 gastric carcinomas was lower than that of patients with other types of gastric carcinomas (P<0.001). The 5-year survival rate for Borrmann type 4 gastric cancer was $19.4\%$ and that for other types was $52.9\%$ (P=0.001). In curative cases, the 5-year survival rates were $32.8 \%$ for patients with Borrmann type 4 gastric carcinomas and $63.4\%$ for other types of carcinomas (P=0.001). Conclusion: Borrmann type IV gastric cancer has more advanced features and a poorer prognosis than other types of gastric cancer. Improving the prognosis for patients with Borrmann type 4 gastric cancer requires early detection and a curative resection.

박성수,김준호,김성완,이성환,박재현,박희찬,Park, Seong-Soo,Kim, Jun-Ho,Kim, Sung-Wan,Lee, Sung-Hwan,Park, Jae-Hyun,Park, Hee-Chan 한국세라믹학회 2002 한국세라믹학회지 Vol.39 No.5

Flux법과 마이크로파 가열법으로 $Al_2(SO_4)_3+2Na_2SO_4$ 및 ${\gamma}-Al_2O_3+2Na_2SO_4$ 분말혼합물로부터 ${\alpha}-Al_2O_3$ 판상체(platelets)를 합성하였다. ${\alpha}-Al_2O_3$ 판상체 형성에 미치는 마이크로파의 영향을 조사하기 위하여 DTA-TG, XRD 및 SEM을 이용하였다. $Al_2(SO_4)_3+2Na_2SO_4$ 혼합물의 경우, 마이크로파로 가열된 시료는 재래식으로 가열된 시료에 비하여 입자의 크기가 작고 응집체로 구성된 ${\alpha}-Al_2O_3$ 판상체로 나타났다. ${\gamma}-Al_2O_3+2Na_2SO_4$ 혼합물의 경우, 마이크로파 가열에 의한 ${\alpha}-Al_2O_3$ 판상체 형성온도는 재래식 가열에 의한 형성온도 보다 낮았다. 또한 마이크로파로 가열된 시료의 형상은 재래식으로 가열된 시료의 형상과 유사하였다. 그러나 마이크로파로 가열된 시료는 재래식으로 가열된 시료에 비하여 입자의 크기가 작았다. ${\alpha}-Al_2O_3$ platelets were synthesized by microwave heating the two different powder mixtures of $Al_2(SO_4)_3+2Na_2SO_4$ and ${\gamma}-Al_2O_3+2Na_2SO_4$ using flux method. DTA-TG, XRD and SEM were used to investigate the effect of microwave on the formation of ${\alpha}-Al_2O_3$ platelets. In the case of the mixture of $Al_2(SO_4)_3+2Na_2SO_4$, the microwave heated sample was ${\alpha}-Al_2O_3$ platelets composed of aggregates with smaller particle size compared to the conventionally heated sample. In the case of the mixture of ${\gamma}-Al_2O_3+2Na_2SO_4$, the temperature to form ${\alpha}-Al_2O_3$ platelets by the microwave heating was lower than that by the conventional heating and the morphology of the microwave heated sample was similar to that of the conventionally heated sample except that the microwave heated sample had smaller particle size compared to the conventionally heated sample.

박성수,김경태,이상은,김병찬,박진,박희찬,Park, Seong-Soo,Kim, Kyoung-Tae,Lee, Sang-Eun,Kim, Byoung Chan,Park, Jin,Park, Hee-Chan 한국결정성장학회 2000 한국결정성장학회지 Vol.10 No.3

마이크로파 열처리공정이 여러 가지 CuO 조성을 가진 $Li_2O-2SiO_2$-xCuO 유리의 전기전도도와 결정화 거동에 미치는 영향을 조사하기 위하여 재래식 열처리 공정과 비교하였다. 각기 재래식과 마이크로파 가열법으로 열처리하였을 때, 시편들의 전기전도도는 CuO 함량이 증가할수록 증가하였고, 각 조성에서 마이크로파로 열처리된 시편이 재래식으로 열처리된 시편에 비하여 높은 전기전도도를 보였다. 또한 X-선 회절 실험 결과, 마이크로파 열처리는 $Li_2Si_2O_5$ , $Li_2Cu_5(Si_2O_7)_2$및 $Li_2Cu_O_3$상의 결정화 정도를 향상시켜주었다. $Li_2O-2SiO_2$-1.3CuO(30 mo1% CuO) 유리를 $500^{\circ}C$에서 30분 동안 재래식과 마이크로파로 열처리한 후 상온에서 측정한 시편들의 전기전도도는 각기 $0.11{\times}10^{-4}(\Omega \textrm {cm})^{-1}$과 $0.68{\times}10^{-4}(\Omega \textrm {cm})^{-1}$이었다. 마이크로파 에너지는 시편들의 결정화를 향상시키고, 전기전도도 값도 증가시킨다고 판단되었다. Effect of microwave heat-treatment processing on the electrical conductivity and crystallization behavior for the $Li_2O-2SiO_2$-xCuO glasses with various CuO contents was compared with that of conventional heat-treatment processing. The electrical conductivities of samples heat-treated at $500^{\circ}C$ by different heat-treatment processing were increased with increasing CuO content and higher electrical conductivities were obtained from microwave heat-treated samples. From the result of XRD analyses, microwave heat-treatment processing enhanced the degree of crystallization in the formation of $Li_2Si_2O_5, Li_2Cu_5$($Si_2O_7)_2$, and $Li_2Cu_2O_3$ crystalline phases. The electrical conductivities of $Li_2O-2SiO_2$-1.3CuO (30 mol% CuO) glass heat-treated at $500^{\circ}C$ for 30 min under conventional and microwave heat-treatment processing were $0.11{\times}10^{-4}(\Omega \textrm {cm})^{-1}$ and $0.68{\times}10^{-4}(\Omega \textrm {cm})^{-1}$ at room temperature, respectively. It was speculated that microwave energy enhanced the degree of crystallization and increased electrical conductivity in the samples.

Purpose: Multiple early gastric cancers were found in $6.9\∼11.7\%$ of patients with early gastric cancer. The goal of this study was to clarify the clinicopathologic features of and to investigate treatment strategy for multiple early gastric cancer. Materials and Methods: Of 967 patients with an gastric adenocarcinoma who were treated by surgical resection during the period of $1993\∼1998$ at the Department of Surgery, Korea University College of Medicine, 267 patients had early gastric cancer. A retrospective analysis of the clinicopathologic differences between the main and the accessory lesions in multiple early gastric cancer was carried out. A comparative analysis was also conducted between solitary early gastric cancer and multiple early gastric cancer. Results: Of 267 patients with early gastric cancer, multiple early gastric cancers were found in 12 patients ($4.5\%$), including 10 men and 2 women. Eleven patients with multiple early gastric cancer had one accessory lesion and 1 patient had 2 accessory lesions. Of the 13 accessory lesions, 7 ($53.8\%$) were located in the same region as the main lesion. The most frequent combination of macroscopic types for the main lesion and the accessory lesion were depressed and depressed types (6 cases, $46.1\%$). The most frequent histologic type of main lesion was a well differentiated adenocarcinoma in 7 ($58.3\%$) of the 12 cases; the accessory lesion was also well differentiated in 4 of those 7 cases. Of the 13 accessory lesions, 4 ($30.8\%$) had been overlooked preoperatively; most of them were located in the lower third of the stomach and were IIb or IIc type and measured less than 1 cm in diameter. Lymph node metastasis was detected in 1 patient ($8.3\%$). The clinicopathologic features of multiple early gastric cancer were not different from those of solitary early gastric cancer. Conclusion: In multiple early gastric cancer, the main and the accessory lesions showed similar differentiation, and lymph node metastasis was less frequent than in solitary early gastric cancer. Therefore, limited procedures, including endoscopic mucosal resection, may be indicated if each lesion of the multiple early gastric cancer fits the criteria for treatment strategy.

Intraoperative breakage of instruments can be occurred unexpectedly. To prevent damage of neighboring important anatomic structures and consequent complications, broken instruments should be removed as soon as possible. There have been several methods to remove broken instruments. One of them is the Carm fluoroscopy which is commonly used for locating metal foreign bodies. However, its application for removal of broken instruments in the oral and maxillofacial area is not common. In our experiences with the removal of two broken instruments in mandibular area, the newly developed dental mini C-arm was used to find broken instrument in soft tissue, because it gives real-time in situ information for the intraoperative location. We report two cases with broken instruments, a broken dental needle in the pterygomandibular space and a broken straight bur in the mandibular angle area. They were identified and could be removed safely using a dental mini C-arm.

카올린으로부터 고분자 젤법에 의한 알루미나 나노입자의 마이크로파 합성

박성수,황채호,김지경,김동현,이상근,박희찬,Park, Seong-Soo,Hwang, Chae-Ho,Kim, Ji-Kyung,Kim, Dong-Hyun,Lee, Sang-Gun,Park, Hee-Chan 한국세라믹학회 2004 한국세라믹학회지 Vol.41 No.9

본 연구에서는 재래식 및 마이크로파 polyacrylamide(PAA) 겔법을 사용하여 카올린에서 추출된 황산 알루미늄 수용액으로부터 육각 판상형의 $\alpha$-Al$_2$O$_3$ 나노 입자들을 성공적으로 합성하였다. 재래식 PAA 겔법에 비하여 마이크로파 PAA 겔 법에서는 상대적으로 겔화 시간은 짧으며, 합성수율은 상대적으로 높았다. 재래식 및 마이크로파 시료들에서 황산 알루미늄의 농도 변화에 따라 나노 입자들의 크기는 거의 변하지 않지만, 가교제의 농도가 증가함에 따라 나노 입자들의 크기는 작아졌다. 가교제의 농도가 0.01M 이상인 조건에서는 재래식 시료들에 비하여 마이크로파 시료들에서 나노 입자들의 크기는 상대적으로 컸다. Hexagonal sheet typed $\alpha$-Al$_2$O$_3$ nano particles were synthesized successfully at various conditions with the aluminum sulfate solution extracted from kaolin through the conventional and microwave assisted polyacrylamide (PAA) gel methods. Shorter gel time and higher yield were obtained in the microwave assisted PAA gel method, compared to conventional method. the size of nano particles was not changed by increasing the concentration of aluminum sulfate, but decreased with increasing the concentration of cross-linking agent in both the conventional and microwave samples. Above 0.01M concentration of cross-linking agent, the sizes of nano particles in the microwave samples were relatively larger than those in the conventional samples.
