This study analyzes the foreign consumers' preferences and the willingness to pay for the Korean traditional dried persimmons by conducting surveys to Japanese, Americans, Canadians, Europeans, Australians, and New Zealanders. The results show that the potential export demand is largest to Japanese and those to U.S. and Europe are sufficient. The results also indicate that the price has to be reduced and the quality has to be improved in order to extend the export demand for the Korean traditional dried persimmons.

The water level and flow rate data measured at Indogyo measurement point which serves as one of the major measuring points of Han River have been very important in aspect of controlling the flow. Because these data are becoming more and more unreliable due to the recent change in the basin or the narrowing of the river width, these data will be standardized by comparing the recent data of Indogyo measuring point with the past those. To minimize the errors of water level-flow rate curve caused by the yearly changes of basin, the standard water level-flow rate curve with respect to the present basin conditions will be set, and calculated reduced water level will be compared with the past data. And through frequency analysis, frequency-based flood level with respect to return period will be presented. Finally, the total flow rate of the flood measured in September, 1990 at the point of Indogyo measuring point will be compared with the total flow of the past extreme floods.

Ondansetron is a novel agent that selectively binds to the 5-hydroxytryptamine_3 receptor, and has been reported to have a prominent effect in the prevention of anti-neoplastic agent induced nausea and vomiting. Twenty solid tumor patients who were scheduled to receive cisplatin containing combination chemotherapy participated in a prospectively open-labeled study to evaluate the antiernetic efficacy and safety of ondansetron. The male to female ratio was 11 : 9 and median age was 49(16-70). The sites of primary neoplasms and number of patients were as following : head and neck 4, metastatic carcinoma of unknown primary site 3, stomach 3, osteosarcoma 2, ovary 2, esophagus 1, melanoma 1, penile 1, bladder 1, cervix 1, and extragonadal germ cell 1. Ondansetron was given as an 8mg loading dose IV before chemotherapy followed by 8mg IV every 8 hours until 24 hours after chemotherapy completion. Complete or major control(0 to 2 emetic episodes) of emesis was achieved in 17 of 20 patients(85%;complete 50%, major 35%) receiving ondansetron during the first 24hrs of chemotherapy. During the period of day 2 through clay 5 of chemotherapy, 14 of 20(75%) patients had complete or major control of emesis(complete 35%, major 35%). No severe side reactions were recorded in ondansetron treated patients, while mild to moderate headache was noted in 20% of patients. These results show that ondansetron is effective in the control of cisplatin induced nausea and emesis, and can be administered safely with minimal side effects.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

This paper analyzes urban residents' preference on rural tourism using a survey data. The results show that even though urban residents are unaware of rural tourism, people who have experienced rural tourism set a high value on it. Urban residents are willing to pay about 93,600Won for rural tourism. These results indicate that there is a lot of potential demand for rural tourism. The results of this paper could be an important information to develop the rural tourism.

Porous silicon layer (PSL) was fabricated by anodic reaction of n^(+) layer of n^(+)/n silicon structures, The dependence of HF concentration, applied bias and reaction time on the porosity of PSL were investigated. FIPOS-SOI bridge resistors were achieved for the application to flow sensors using n/n^(+)/n silicon structures, Those resistors are thermally isolated by oxidized porous silicon. The SOI bridge was 50μm wide, 900 μm long, and 5μm thick, Measured TCR(temperature coefficient of resistance) was 1.1x10^(-3)/℃.

Blunt or nonpenetrating chest injuries are common after motor vehicle accidents or falls. Blunt injury to the heart ranges from contusion to rupture. Cardiac rupture, however, is un-common and associated with a very high mortality rate ; left ventricular rupture due to falling is even more rare. We experienced a case of left ventricular rupture of the heart caused by a fall, which the patient survived. A 63-year-old man fell off a ladder and presented with hypotension from left hemothorax and pericardial tamponade. The hemothorax was relieved via an emergency closed thoracostomy but dyspnea and hypotension continued. And so, echocardio-graphy was done and pericardial tamponade was detected. Emergency left thoracotomy was done to repair the rupture site. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and immediate surgical treatment.
