Thymoma is associated with myasthenia gravis, Pure red cell aplasia, and autoimmune diseases such as autoimmune hemolytic anemia, aplastic anemia, and hypogammaglobulinemia. It's association with aplastic anemia is rare and aplastic anemia appearing after surgical removal of thymoma is especially rare. The authors hereby report a case of aplastic anemia occuring in a patient who was diagnosed with thymoma and myasthenia gravis and had the tumor surgically removed. The patient was treated with anti-thymocyte globulin, cyclosporin, and prednisolone, and showed partial remission with hematologic improvements after 12 months.

Background and objectives : The long-term survival in patients with non-Hodgkin's lymphoma (NHL) after conventional dose chemotherapy is about 35% and the rest of the patients tend to have relapse. So, in relapsed or refractory NHL, we compared the outcome of patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation(APBSCT) with only salvage chemotherapy of cisplatin, dexamethasone, mitoxantrone, and etoposide(CDME). Materials and methods : From June 1993 to December 1999, 25 patients with relapsed or resistant NHL were treated with CDME regimen as salvage chemotherapy. Twelve patients were received four cycles of CDME chemotherapy, and 13 patients were received high-dose chemotherapy with APBSCT following two cycles of CDME chemotherapy. Results : The median follow-up duration was 12.8 months(range:4-68). The overall response rate was 41.7% (complete response rate 25%, partial response rate 16.7%) in 12 patients with CDME only. Thirteen patients who were treated with high-dose chemotherapy with APBSCT achieved 61.5% complete response rate and 15.4% partial response rate, with an overall response rate of 76.9%. The estimated 3-year progression-free survival rate was significantly higher among patients who received high-dose therapy than patients who received CDME only(41.5% vs 20.0%, p<0.05). And, 3-year overall survival rate was significantly higher among patients who received high-dose therapy(51.3% vs 25.0%, p <0.05). Conclusions : In relapsed or refractory NHL, CDME chemotherapy is an effective salvage chemotherapy and allow peripheral blood stem cell collection. Also, high-dose chemotherapy with APBSCT following CDME is superior to CDME salvage chemotherapy only.

In the manufacturing process for obtaining reduced sponge iron from pickling-oxide, the production of sponge iron is strictly controlled by pre-reduction process of the pickling oxide bed by coal coke and anthracite. Consequently for the increased of this product, the fundamental knowleadge of a reduction mechanism of the packed bed has to be reviewed. In this study, time dependences of fractional reduction R for a packed columnar iron oxide bed at 1100℃ were measured for various kind of iron oxides with various particle size, using reducing agents, coal coke and anthracite. Fractional reduction R is measured for ratio of outer diameter of unreacted part r_0 and that of sponge iron r, R=1-(r r_0)^2.

인터넷은 디지탈 형태의 다양한 정보를 신속하게 전달한다는 점에서 매우 각광을 받고 있다. 그러나, 대량의 인터넷 정보 중에서 자신이 원하는 정보 자원을 정확하게 많이 얻어 낼 수 있는 방법의 제공은 매우 어려운 문제이다. 본 논문에서는 인터넷 정보 자원의 메타데이타를 관리하기 위해 SeriCore라는 SGML 형식의 메타데이타 DTD(Document Type Definition)를 정의하고, 이들 메타데이타를 효율적으로 저장하고 검색, 관리할 수 있는 시스템을 설계, 구현하였다 The Internet has gained popularity because ot provides various information in digital format. However, it is very difficult to provide methods which make it possible to search adequate information resource from bulk of Internet information. In this paper, we define a SGML metadata DTD, named SeriCore, and design and implement a metadata retrieval and management system which can store, retrieve and manage the Internet metadata efficiently

The purpose of this study is to examine the change of health related physical fitness. The study conducted the experiment with 24 participants; three groups fo eight participants in each age group(40, 50 and 60's) The subjects are members of the G sports center. The results of this study are as followed. According to comprehensive results of the research, circuit weight training for 12 weeks appears to give a positive effects on middle aged men's health, and that large increase in body fat and lower strength is not an unavoidable result of aging but the result of an unhealthy life style. Putting the proper training for the middle-aged group into systematic and regular practice, exercise can delay the normal aging process and also maintain relative good health physiologically. I think we need to develop more rational and scientific exercise programs to build up physical strength and improve health.

중국 산업별 취업구조 변화 연구

After China carried out the policy of economic reform and opened its gate to foreign intercourse, market competition in the industry became keen. This caused serious unemployment problems and it threatened economic advance and social stability in China. If Chinese government can't settle these problems, economic development can't be expected in the future. This paper focuses on degrees of contribution of three major industries to national economy, analyzes employment structure, predicts changes in employment by industries after China's joining WTO and helps Korea easily access and approach to China. This study proves that the degrees of contribution of three major industries to GDP in China differs through by industries. GDP component proportion in primary industry shows a downward tendency. In secondary industry it is at a standstill and in tertiary industry it goes on increasing. In the area of employment, after the reform and gate opening, tertiary industry makes great progress and produce output value and employment rate in tertiary industry ascend rapidly. On the contrary, employment rate in primary and secondary industry descends. In the field of foreign investment, foreign capitals imported in primary industry are few. Most of them are invested in secondary industry. The amount of foreign capitals imported in tertiary industry have been slowly increasing. But China's recent joining to WTO accelerates the investment in tertiary industry. After the economic reform, large amount of residuary labor force switched into the labor in industry segment at the early stage was created. From late 1990's, however, increasing unemployment in industry segment caused by industrial structure adjustment such as government-owned enterprise reform made it hard to absorb agricultural labor. Instead of industry segment, tertiary industry embarked itself in absorbing agricultural labor from late 1990's and much of agricultural residuary labor force was switched to tertiary industry labor. This tendency is expected to continue and increase for the time being. Secondary industry in which manufacturing occupies 90% have been decreased from 1998. Among 15 branches of trade in manufacturing 11 branches except sewing, leather, timber processing, electric machine and communication facilities are losing their laborer. It means that there has been a decrease in resources intensive field and traditional branches while labor-intensive maintains its power. Laborers in tertiary industry are increasing each year and the percentage of employment in traditional branches is the highest. The rate of employment increase is higher in emerging branches. Therefore continuous development is expected in these branches. Synthetically, primary industry tends to sink in occupancy rate and the percentage of employment, secondary industry shows the tendency of gradual fall, whereas tertiary industry will develop and increase and ultimately become the core industry which is going to have strong effect on Chinese industrial development.
