  • Purpose : Stem cell transplantation (SCT) has gained worldwide acceptance as a treatment for hematologic disorders. This study was performed to evaluate the clinical characteristics and outcomes of the acute kidney injury after SCT in children. Methods : The records of 53 patients who were treated with SCT at the pediatric department of Yeungnam University Hospital between January, 1996 and April, 2009 were used as subjects. Their were divided into two groups ; 'Early renal insufficiency' (ERI, n=18) and 'Non-early renal insufficiency' (NERI, n=35). ERI had greater than 25% of drop in GFR after SCT. Results: Total 53 patients were analyzed. In cord blood SCT (n=11), ERI was 4 (36.4%) and NERI was 7 (63.6%). In bone marrow SCT (n=16), ERI was 8 (50.0%) and NERI was 8 (50.5%). In autologous peripheral blood SCT (n=26), ERI was 6 (23.1%) and NERI was 20 (76.9%). There is no difference in both groups according to kinds of SCT. GVHD was developed in 22 patients, and there is no difference in each group. Twenty two of 53 patients died. ERI was 12 (66.7%) and NERI was 10 (28.6%). Acute renal failure is most important cause of the deaths. Conclusion : Out of 53 pediatric patients who were treated with SCT, 18 patients had greater than 25% of drop in GFR. There is no difference in both groups according to kinds of SCT. GVHD was found in 22 patients and there is no relation between GVHD development and acute kideney injury.

  • This essay explores Chinese literary circles of 1919, specifically the New Youth literary coterie. The changes which occurred during this period are examined through a chronological account of the tensions and interactions which arose between contributors to New Youth and other literary publications, especially The Weekly Review and Renaissance. The founding of The Weekly Review by some of the New Youth literary coterie displayed their competitive ethos as well as their hopes for the "new era" as a expression of "mutual assistance." Renaissance was founded by Peking University students, and the editors of New Youth saw it as a useful platform to promote their ideas to the younger generation. The editors of Renaissance described themselves as "night cats" and "brazier flames," and they distinguished themselves from earlier generations through their relentless academic fervor. These three publications, New Youth, The Weekly Review, and Renaissance, together formed an influential triangle which successfully dominated Chinese literary circles by scapegoating traditional intellectuals in their quest to establish the new era. After the May Fourth Movement, however, their paths divided. Following the arrest of Chen Duxiu, Hu Shi sought to change the direction of The Weekly Review by focusing on "problems." This reinforced the academic emphasis of Renaissance, and in contrast New Youth became politically more radical, starting with a "Special Issue on Marxism," and also relocated from Shanghai to Beijing. Chinese literary circles subsequently became increasingly concerned with academic trends and political issues. Interestingly, the New Youth literary coterie became ashamed of their former stance, which encouraged their role in the independence movement of Choson Korea.

  • 송수신기 일체형인 소형 루프 시스템을 해저 전자탐사 기술의 적용 가능을 확인하는 과정의 시작 단계로 자기 쌍극자 송신원을 이용한 층서구조에서의 전자가 반응을 계산 하였다. 전도성인 해양 환경에서 측정되는 신호의 크기가 작은 한계가 있지만 전자기장 반응 해석을 통행 지하 하부의 정보를 얻을 수 있었다. 기반암 위의 층이 바닷물보다 저항성인 해저 지각인 경우와 전도성인 열수광상인 경우에 따라 반응이 달라짐을 확인하였고, 그 층의 두께에 따라서 변화하는 전자기 반응을 계산하여 탐지 가능한 층의 두께를 예상할 수 있었다. 송수신기가 모두 바다 속에 위치하기 때문에 송수신기의 배치 방법과 송수신기가 해저면에서 떨어지게 될 때 신호의 반응 변화를 파악하였다. 해양 소형 루프 전자탐사의 실제 적용을 위해서 이상의 연구들이 기초가 될 것으로 기대된다.

  • Multi-band and multi-mode transmitters are needed for SDR and CR. Recently many types of polar transmitters have been studied in order to implement a multi-band and multi-mode transmitter. Polar transmitters have many advantages, such as a simple structure, high efficiency and etc. In this paper we consider the number of D/A bit and the effects of a delay mismatch as design parameters for implementing polar transmitters. From the simulation we know that a 10 bit D/A is sufficient and a delay mismatch must be maintained small than 1/64 chip for satisfying the spectrum mask characteristics. We implement a polar transmitter based on the design parameters and the measured output signal meet the spectrum mask of 800MHz CDMA.
