The synthesis process of iron carbide was proceeded in two stages of reduction of hematite fines by H₂ gas, and carburization of the reduced metal by CO-H₂ gas mixture at 600℃. The surface of reduced iron was pre-treated with an addition of 0.05 vol% NH₃-Ar before carburization. The synthesized iron carbides were comprehensively explored by C/S analyzer (Low C/S determinator), Mossbauer spectroscopy, X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy at various reaction times of 5, 10, 15, 20, 25, 30, and 35 min. By addition of a small amount of NH3 gas, the super iron carbides contained 10 wt% carbon were made, and such addition stabilized iron carbides. It was found that addition of NH3 gas played a major role in the formation of iron carbide without decomposition (Fe₃C→ 3Fe+C) of iron carbides and precipitation of free carbon. From these results, we succeed in synthesis of super iron carbide, Fe_(5)C₂, with a stable single phase without Fe and Fe₃C phases. (Received August 2, 2004)

A 4 years old male poodle dog with gastro-intestinal distress was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. The patient was presented with history of vomiting, hemorrhagic diarrhea and inappetence. Laboratory evaluation revealed that WBC (23.8 x 10^(3)/㎕). BUN (87.9 ㎎/㎗), creatinine (7.3 ㎎/㎗) and phosphate (9.6 ㎎/㎗) was elevated, and proteinuria, hematuria and bilirubinuria were detected on urinalysis. Increased renal cortical echogenicity and parenchymal calcification of kidney were observed by ultrasonography. Based on the findings of history, clinical signs, laboratory assessment and ultrasonography, it was diagnosed as acute renal failure. The present patient showed favorable therapeutic response by fluid therapy. diuretics, peritoneal dialysis and blood transfusion.

대장 지방종은 주로 우측 결장에 호발하고 특히 회맹판 부위와 맹장 부위에 호발한다. 또한 50~60대에 빈도가 높고 증상이 있는 환자에서 장중첩증이 높게는 40~50%에서 보고되고 있어 성인 장중첩증의 원인으로 중요한 비중을 차지한다. 특히 성인 장중첩증 및 장폐쇄의 중요 원인인 악성 종양과 임상 양상이 유사하여 감별진단이 중요하다. 저자들은 반복적인 복통을 주소로 내원한 환자에서 맹장의 4×5㎝의 점막하 지방종이 말단 회장부위와 반복적인 장중첩중이 발생했던 1례를 부분 절제술로 치료하여 양호한 임상 경과를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Lipomas are one of the most common benign nonepithelial tumors of the colon which are often detected incidentally by radiologic investigation or on operation. These tumors are usually without specific symptoms. Colonic lipomas occur most often in the right colon, particularly in the ileocecal valve and the cecum. Most patients are asymptomatic. but tumors larger than 2 cm tend to produce a change in bowel habit. abdominal pain. rectorrhagia and complications including luminal obstruction or intestinal intussusception. Diagnosis can be made by colonoscopy abdominal CT. MRI, or barium enema. We report a case of lipoma of the cecum that originated in the submucosa and presented as a intussusception in a 50-year-old woman with a brief review of the literature.
우루과이 라운드(UR) 協定 시장개방조치의 國民經濟 및 農業部門 效果

본 논문에서는 다국간 일반균형 모형을 이용하여 우루과이 라운드 협정이 국민경제 및 농업부문에 미친 영향을 분석하였다. 분석결과 UR 이행에 따른 후생효과는 경제규모가 큰 선진국이 크게 증가하는 것으로 분석되었다. 우리나라는 UR 이행에 따른 영향으로 농업부문의 산출이 감소하였고, 이로 인해 농업부문 GDP도 감소하는 것으로 나타났다. 또한, 수입농산물과 국산농산물의 대체성이 커질수록 농업부문 GDP 감소폭은 더욱 커지는 것으로 분석되었다. This paper focuses on the impact of the Uruguay Round (UR) implementation on Korean economy and agriculture using a multi-regional general equilibrium model. The main results of this study as follows. The impact of the UR on welfare increases in developed countries more than developing countries. The results of this study show that the Uruguay Round has had a negative impact on agricultural production in Korea. As expected from a high value of substitutability among agricultural sectors, there are considerably more losses to the agricultural GDP in Korea.

In this thesis, a method of solving the IP(Internet Protocol) address collision problem on the Web browser in the TCP/IP based on LAN(Local Area Network). These days a number of computers are increasing in geometrical progression, but general users who are not experts are lack of the knowledge about TCP/IP address, by they may use not only their own but also other users' TCP/IP addresses by mistake or intentionally. For the more they may use IP address which is the same as network equipments and then the situation will cause the whole network to be disturbed. As the result it may be happened that not only the original users' network but also the whole users' one do not operate properly in the LAN. In this thesis, the system proposed in this thesis collect address informations of personal computers which are objects of management in local area network and network systems (sever, workstation) and find whether the address informations which are used at that time are the same with the exact which are stored, and then compares with IP address information in the RARP packet on the WEB Browsers. And therefore want to protect the disturbances of network system caused by address change which are occurred by design or by mistakes. It is demonstrated that it can be protected by using the suggested method.

Various cytokines including IL-1β, IL-2, IL-4, IL-10, IL-12p40, IFN-γ, and TNF-α have been recently reported to play important roles in both host and donor cell activations during xenotransplantation. Interleukin (IL)-18, a proinflammatory cytokine, can induce IL-4 and IL-13 production in T cells, NK cells, B cells, mast cells, and basophils. IL-18 has the capacity to stimulate innate immunity and both Th1-and Th2- mediated responses, but little is known to involve in the xenograft rejection. In order to investigate the role of IL-18 in xenograft rejection, we transplanted the pig kidney (PK15) cells to C57BL/6 mouse with or without intraperitoneal injection of mouse recombinatant IL-18. It was analyzed the population of T cell, B cell and NK cell in the mice transplanted with PK 15 cells and recombinant IL-18 by flow cytometry. We found that splenic CD3+ T cells were increased in mice injected PK15 cells with recombinant IL-18. These results suggest that recombinant IL-18 is critical in the xenograft rejection by increasing T cell population of the recipients.

The inflammatory myofibroblastic tumor (inflammatory pseudotumor) is a rarely occurring soft tissue lesion of unknown etiology. It can be of any location, but commonly it is found in lungs. It has been considered as a nonneoplastic reactive inflammatory lesion, but nowadays, confusion and dispute about its character is increasing due to its high recurrence rate and metastasis. We present a patient who had been diagnosed with an inflammatory pseudotumor in the right maxilla area, 1 year before visiting our hospital. After that, her pain and swelling did not resolved and she visit our hospital. On radiographic examination, aggressively infiltrative growth of the lesion with destruction of adjacent bony structure was noted. We found unusual aggressiveness of the inflammatory myofibroblastic tumor of the head and neck region. Because the typical behavior of the inflammatory myofibroblastic tumor is not defined yet, we recommend the surgical excision of the lesion and close follow-up.
