The fatty acid composition of shiitake mushrooms cultivated at the mushroom farms under the identical condition was analyzed using a GC-FID. The lipids in mushrooms were extracted with a solvent mixture of methanol and chloroform. The lipids were saponified and methylesterified to make fatty acid methylesters (FAME). The FAME was isolated, identified and quantified using a GC-FID with a highly polar cyano-siloxane type capillary column. Linoleic acid was the most abundant fatty acid, representing about 74-81% of total fatty acids. Palmitic acid was the second most abundant fatty acid found in shitake mushrooms. The composition of fatty acid metabolite profiles were not greatly different with harvesting cycles. However, the contents of fatty acids in mushroom was greatly dependent on the harvesting cylcles. The fatty acid of contents in mushrooms obtained at the 1st harvesting cycle was much higher than those in mushrooms obtain at the 3rd harvesting cycle.

본 논문은 LBS기반 모바일 시스템 구현을 위하여 GoF의 디자인 패턴을 활용한 효율적인 설계방법을 제안하고자 한다. 본 논문에서 제안된 설계기법은 사용자와 모바일 시스템 관점에서 디자인 패턴의 생성패턴, 구조패턴, 행위패턴을 이용하여 모바일 시스템 인터페이스를 설계하고 구현한다. 디자인 패턴을 활용한 설계 방법은 소프트웨어 개발에 있어서 모듈 및 소프트웨어 재사용성 증가, 개발시간을 단축, 유지보수 최소화, 시스템의 메모리 절감 효율성을 보여준다. 따라서 본 논문은 모바일 환경에서 지리정보시스템을 접목한 미들웨어를 개선하기 위해 디자인 패턴을 활용하였다. 본 논문은 모바일 시스템에 디자인 패턴을 적용하여 높은 안정성과 신뢰성을 보여주고, 모듈 및 소프트웨어의 재사용과 확장성을 높이며 효율적인 시스템을 개발하는데 기여할 것이다. This paper will propose the efficient method that should be designed to utilize the design pattern of GoF(Gang of Four) for implementation of LBS(Location Based Service) mobile system. The design method proposed by this paper can design and implement system interface using creational patterns, structural patterns and behavioral patterns of design pattern from the user and mobile system viewpoint. The design method using design pattern can show increasing reusability of module and software, abridging the development time, minimizing the maintenance and decreasing the efficiency of memory of system to software development. Therefore, we used a design pattern in order to change the middleware applying geographic information system from mobile environment. Finally, the mobile system applied to design pattern shall contribute to showing high stability and reliability, improving reusability and scalability of module and software and developing efficient LBS mobile system.

Purpose : The aim of this study is to analyze the clinical results of thermo-irradiation treatment for surgically unreserctable advanced hepatoma with or without hepatic arterial chemo-embolization (HACE), chemotherapy (CT) and interferon (IFN) therapy. Materials and Methods : Between February 1990 and December 1992. 45 patients with surgically unresectable advanced hepatomas were treated by thermo-irradiation with or without hepatic arterial chemo-embolization and other treatment modalities. Among them, We analyzed retrospectively 24 patients who received more than three times of hyperthermias. Mean age was 50 years (range : 18-71 years) and male to female ratio was 20:5. In the study, treatment was administered as follows : 3patients received radiation therapy(RT) and hyperthermia (HT). 3 received RT+HT+CT. 3received RT+HT+HACE. 1received RT+HT+CT+HACE. 2 received RT+HT+CT+IFN. 10 received RT+HT+HACE+IFN. 3 received RT+HT+CT+HACE+IFN. Radiation therapy was done by a 6 MV linear accelerator. Patients were treated with daily fractions of 180 cGy to doses of 11gy-50Gy (median 30Gy). Local hyperthermia was done by HEH-500C(Omron Co.Japan), 30-45 min/session, 2 sessions/wk and the number of HT sessions ranged from 3 to 17 (median 7 times). 15 patients of 25 were followed by abdominal CT scan or abdominal ultra-sonogram. The following factors were analyzed : Age, histologic grade, sex, number of hyperthermia, total RT dose, hepatic arterial chemo-embolization. Results : Of 25 patients, there were observed tumor regression (partial response and minimal response) in 6(24%), no response in 8(32%), progression in 1(4%) and not evaluable ones in 10(40%) radiographically. The over all 1-year survival was 25%, with a mean survival of 33 weeks. The treatment modes of partial and minimal responsive patients (PR+MR) were as follow : Two were treated with RT+HT+HACE 2 were done with RT+HT+HACE+IFN Remaining 2 were treated with RT+HT+CT+HACE+IFN. The significant factor affecting the survival rate were RT dose (more than 25 Gy), HACE, number of HT(above 6 times), responsiveness after treatment (PR+MR). Age, sex, histologic differentiation, chemotherapy, interferon therapy were not statistically significant factors affecting the survival rate. Conclusion : Although follow-up duration was short, the thermo-irradiation with/without hepatic arterial chemo-embolization was well tolerated and there were no serious complications. In future, it is considered the longer follow up and prospective, well controlled trials should be followed to evaluate the efficacies of survival advantage.
