On September in 2010, myxosporidian parasites were found on the fins of Chinese muddy loach, Misgurnus mizolepis, Several cysts of approximately 2 mm diameter were observed on the fins. Numerous spores were found in the cyst. The total length of the spore was 13.0 to 15.8 ${\mu}m$, and the width of spore was 6.0 to 7.5 ${\mu}m$. As the results, the myxosporidians were finally identified as Thelohanellus misgurni (Kudo, 1919) on the basis of the presence of characteristic cysts and size of spores.

This study is mainly to investigate the influences of both Western's utopian socialism and cooperatives ideas on the process of China's rural cooperation from 1919(the occurrence of 5.4 movement) to 1958(the completion of People's commune). To accomplish this, first, we will discuss that how these two ideas emerged as an alternative to Western capitalism in the before/early 20th century were introduced into China and how these ideas effected on the process of the China's Communist Revolution. Then, we will review the process of China's rural cooperation during the 1950s' new socialist nation-building period since the foundation of New China(1949), the sharp debates about rural cooperation in the process of its realization, and the reasons of radically promoting rural cooperation in the late 1950s. Finally, through these debates and experiences regarding rural cooperation in rural China during 1919-1958, any implications in solving rural cooperation problems of contemporary China facing difficulties will be provided.

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.

Overhead cranes consist of trolley, girder, rope, objects, trolley motor, girder motor, and hoist motor. If objects are regarded as mass point, and the acceleration of hoisting motion for objects is neglected, analytical model of overhead cranes becomes a nonlinear model because the length of a rope changes. Equations of motion this model is derived of simultaneous differential equations fur motors and object. Positions of the model are controlled by optimal inputs which obtain from a nonlinear optimal control method. From the results of computer simulation, even if initial states of objects suing, it is founded that position of overhead cranes is controlled, and that swing of objects is suppressed.

In general, Diode rectifier has been applied to DC traction power supply system. Diode has some characteristics which is voltage drop in inverse proportion of load because of non-controlled switch, and cannot flow a current in reverse bias. So, voltage drop occurs frequently, and regenerated power cannot use in substation. The PWM rectifier is able to control output voltage constantly to reduce voltage drop and to use regeneration power without additional inverter. This paper proposes analysis algorithm for DC traction power supply system with PWM rectifier.

오는 4월 13일은 임시정부수립기념일이다. 이에 상하이의 인쇄사에서 잠시 근무했던 이봉창 의사와 독립선언서를 인쇄했던 보성사에 대해 알아본다. 이봉창 선생은 1932년 1월 8일 일본제국주의의 심장부인 도쿄에서 삼엄한 경호를 받으며 궁성으로 돌아가던 일왕에게 수류탄을 투척, 일본인의 간담을 서늘케 하고 전 세계 피압박 민족에게 큰 충격을 준 인물이다. 이 선생이 터뜨린 한발의 수류탄은 당시 침체일로에 있던 상해임시정부에 새로운 전기를 마련해 주었다. 정부는 지난 62년 선생의 장거를 기리어 건국훈장 대통령장을 추서했다. 보성사터 기념비는 지금의 조계사 좌측 수송소공원에 있는데, 천도교에서 경영하던 인쇄사로 보성학교 뒷마당에 자리 잡고 있었다. 1919년 당신 최남선이 경영하던 신문관과 함께 최대 인쇄사로 꼽혔다. 보성사는 1919년 6월 28일 일본의 방화로 추정되는 화재로 전소됐다.
