Anthracnose symptoms severely occurred up to 50% on leaves of English ivy growing in greenhouses in Cheongwon area of Korea during disease survey in April, 2000. The symptoms developed as concentric spots with dot-like acervuli on leaves of the plant. A total of 24 isolates of Colletotrichum sp. were obtained from the spotted lesions and identified as Colletotrichum trichellum based on the morphological and cultural characteristics. Leaf spots similar to the original anthracnose symptoms were induced on the host leaves by artificial inoculation with the isolates of the fungus. This is the first record of C. trichellum causing anthracnose of English ivy in Korea.

BACKGROUND: Endoscopic Ultrasonography(EUS), a combination of endoscopy and ultrasonography is one of the most useful tools for diagnosis of digestive system diseases. EUS is useful in staging the primary tumor invasion and regional lymph node metastasis because of its ability to image the gut wall and adjacent structures in unique detail. We performed a study preoperatively for assessing the accuracy and limitation of EUS in gastric carcinoma. METHODS: In 75 patients(Male 54, Female 21, Mean age 62.3 years) with a gastric carcinoma confirmed by endoscopic biopsy, we performed EUS preoperatively. The results were compared with the postoperative histopathologic staging. RESULTS: 1) In assessing the depth of tumor invasion, EUS accuracy on depth of invasion was 76.0% and overstaging and understaging were 14.7% and 9.3%, respectively. 2) In assessing the lymph node metastasis, the accuracy rate of EUS was 65.3%. A rate of false-positive diagnosis was 27.3%, and a rate of false-negative diagnosis was 24.5%.3) In assessing the incidence of lymph node metastasis for each T stage, the involve rate was 10.5% in pT1, 36.4% in pT2, 95.7% in pT3, 100% in pT4. CONCLUSIONS: EUS is the most accurate diagnostic methods presently available to determine tumor infiltration depth and lymph node metastasis.

OBJECTIVE: The consolidation of health information has led to the creation of a national network of medical institutions. In this wireless and hard-line communication web, patients' medical information, which is extremely private and must be kept in secret, may leak out, and the risk of dangers such as privacy infringement and misuse of information has increased. METHODS: For this dissertation, a patient information protection algorithm was designed for a hospital information system in order to improve the untraceability and anonymity of patients' individual information in a ubiquitous computing environment. RESULTS: Additionally, analyzing the computing load showed that the computing load of the entire system did not increase, and since 57 percent of the sensor node's computing load was transferred to the secure server, the sensor node's load was minimized. Thus, the system can also be applied to low performance sensor networks. CONCLUSION: In conclusion, improving the security level of identification information transmissions while minimizing the computing and communication load of sensor nodes in a ubiquitous computing environment did not lead to an increase in the system's overall computing or communication load. Thus, a system with improved security features for identification information and communication information was developed and established.

Cancer of the vulva accounts for approximately 0.5% of all gynecologic malignancies. At diagnosis, one-third of these cases is detected in an advanced stage (FIGO stages III, IV), and local extension of primary vulvar cancer may involve adjacent midline structures such as the clitoris, urethra, vagina, and anus. Initial surgical therapy of such locally advanced primary cancers may compromise the functional integrity of midline structures, necessitating ultraradical surgery including pelvic exenteration. In view of the relatively elderly age of the patients and the morbidity of this ultraradical dissection, concomitant chemoradiation therapy - that the efficacy had been proven in head and neck cancer, anal cancer has approached for patients with locally advanced vulvar cancer. We experienced a case of stage III vulvar cancer patient, who underwent concomitant chemoradiation therapy with 5-fluorouracil(FU) and cisplatin and who showed complete response. So, we report this case with brief review of the literatures.

Despite on-going efforts to control malaria, the rate of malaria has not decreased throughout the world. It was believed that endemic malaria had been eradicated in Korea since the end of the 1970s, however it reemerged from 1993 and has been increasing ever since. Besides endemic malaria, imported malaria is also increasing in Korea as the number of overseas travellers and foreign workers increases. We discovered malaria in a two-year-old child who visited Sierra Leone with his missionary father. The patient contracted malaria despite chemo-prophylaxis with chloroquine and was diagnosed as falciparum malaria by blood smear examination and IFAT. He successfully recovered after administraion of quinine and clindamycin without complication. However, the malaria did not respond quickly to chloroqine and Fansidar but a drug resistence test was not performed.
