The incidence of bleeding complications may be decreasing. But, upper gastrointestinal(UGI) bleeding is a still significant complication of chronic renal failure(CRF). Although there are many controversies about clear cut guidelines for blood transfusion, blood transfusions are critically important and essential in many emergency cases. Recombinant erythropoietin has been used in the past in treatment of anemia in Jehovah's witness patients from surgery, chemotherapy, and trauma. We here report a case of the use of erythropoietin in Jehovah's witness patients with an active upper gastrointestinal bleeding and chronic anemia from end-stage renal disease. A 59-year-old male Jehovah's witness patient with a past medical history of diabetes mellitus and end-stage renal disease(receiving hemodialysis) was admitted because of hematemesis and melena. He was diagnosised with gastric ulcer on emergency gastroenteroscopy and treated with argon plasma coagulation. His hematocrit was 12.1% at admission. He refused blood transfusion and was treated with intravenous iron, ulcer medication and high dose erythropoietin. After 2 weeks, he was discharged with hematocrit 23%.

In recent years just after IMF economic crisis, inbound market in Korea has recorded in a plus comparing to before ME crisis. However, inbound from Europe showed no development and rather in a decreased trend in these years. The purpose of this article is studying the reason why the inbound tourists volume show decrease and how the tourists from Europe can be increasable by any points of promotional strategy. For this purpose, an Empirical investigation has made during September 1999 for the European visitors selected by 5 majors of inbound travel agencies in Seoul. On this investigation, Four steps of Tourist Behavior's theory by which has applied, Clawson are adopted in examining the determinant sectors of traveling other countries. The major results are as follows. 1. Tour items suitable to European tourists should be developed soon because tour items advertised by Korean travel agencies are not so enough to decide easily for traveling to Korea. Also developing the symbols of Korea be required. 2. Strategical advertisement for Korea are required from the tour planning stage to the time of return for tourist. 3. Major complaints like medium priced hotel, unkindness of taxi drivers, toilets facilities, short of travel sign board and others factors have to be considerable in policy. 4. Task-force team for having the effective market policy should be carried out between goverment, travel agencies and KNTO. 5. We need to broaden the ideas of Europe to Middle East and Africa as most of Africans' and Middle East countries had been under the colonization of European countries. Accordingly, developing these countries which are, so-called, sun-rising market in tourism are much helpful if we devlope the European tourists strategically. Finally, somebody say that this coming New-Millenium is the age of tourism. In order to greet the New-Millenium with the hopeful tourism vision, promotional strategy in tourism is to be performed soon.

Multilocular cystic nephroma is a rare and non-inherited benign renal neoplasm occuring in the both children and adults. It is necessary to make a differential diagnosis from all renal diseases with a cystic component, such as simple cyst, metastatic renal tumor, cystic adenoma or angiomyolipoma in adults. We report a case of multilocular cystic nephroma presented with painful abdominal mass treated with laparoscopic nephrectomy and confirmed with pathology.

Hyponatremia is the most common electrolyte disorder in hospitalized patients, and incidence of hyponatremia is about 1-4%. It is suggested that hyponatremia is closely related with morbidity and mortality in these patients. Diuretic-induced hyponatremia is one of the most common causes of hyponatremia associated with hypovolemic hypoosmolality, but serious hyponatremia due to diuretic use is relatively uncommon. Advanced age may be a predisposing cause, and women is more susceptible than men, but no definite proof has been documented. The severity of symptoms can be roughly correlated with velocity and degree of hyponatremia, and neurological symptoms generally do not occur until the serum sodium falls below 125 mEq/L. Rapid development of hypoosmolality can result in brain edema before brain adaptation occurs by excreting intracellular solutes. In the most severe cases death can result from respiratory arrest after cerebral herniation. So, it is need to optimal treatment for neurological symptoms. We report a case of serious thiazide-induced hyponatremia in elderly hypertensive man which were aggravated by infusion of simple dextrose solution without electrolyte for severe watery diarrhea.

In the point of view a protective relay, the selectivity and sensitivity is very important in its performance. The correct setting of the relay parameter is required. The verification of accurate setting for the protective relay is very difficult before a actual fault occur. In this paper, we proposed the diagnosis expert system as a method to verify the correctness of the relay setting. The developed system proved effectiveness through the tests on the real systems.

The purpose of this study was to offer the basic information to develop multiple anxiety test (cognitive, physiological, behavior) for Judo player, The Subjects were 107 male judo players who had been participated into The spring season univer- sity judo match. Raw data were analysed from 100 subjects. The qustionnaire to test was CASI -2 by Martens(1990). The statistical analysis used frequency and X^(2). The following conclusion were made : 1) The cognitive anxiety of judo player were showed the highest on match re- sult, were shewed the most denial response on attention. 2) The physical anxiety of judo player were showed the highest on digestive organs. Judo player were showed slight response of anxiety on physiological change. 3) The self- confidence anxiety of judo player were more significantly changed by psychological values than physical values. AS a conclusion, this study can be auggested that sport pscychologist have to develop detailed state anxiety test questionnaire invovling match result, digestive problem, and confidence considerated match importance.

By the result of critical analysis based on the Multi-Regional IO Model for the whole country that divided into 8 boundaries of land, the whole national demand in tourism showed the 34.2% of increase by the impacts of tourism investment on regional economic growth. However it also analysed that the economical gap between the regions through these investment showed more broaden and wider than before. Accordingly in order to mollify the economical gap between the regions but with the encouragement of product increase, the policy scenario on the distribution of investment resource had designed effectively for the analysis per each scenario. In consequence of this policy analysis, all of the scenario showed that it had mollified the economical gap between the regions comparing to the tourism investment of 7 culture tourism belts.

To improve passenger safety, seat belt systems with pre-tensioner that tightens seat belt webbing using explosive just before collision are widely used these days. Even though seatbelt must not unlatched without passengers' operation. explosive power of pre-tensioner can cause unlocking of a buckle. To prevent the unlocking, an anti-g mass that blocks displacement of the release button has been attached to the buckle. In this study, the dynamics and statics of locking mechanism associated with operation of anti-g buckle has been theoretically investigated, and important design variables that affect the operation of anti-g buckle have been identified. Through the total seat belt system's dynamic simulation using force and displacement inputs obtained from seat belt sled test, design of the proposed anti-g buckle has been validated.
