In military applications of equipment, it is of the utmost importance that the equipment operates without breakdown for a specified length of time. We can increase the reliability of a system by adding redundant components to the basic nonredundant system. This study introduces a dynamic programming algorithm of finding optimum redundant design that maximizes the system reliability with constraints.

교통사고 발생현황에 따르면 2005년 한 해 동안 214,171건의 교통사고로 6,376명이 사망하고, 342,233명이 부상하였으며, 이중 야간 교통사고는 총 104,611건으로 전체 교통사고 건수의 48.8%를 차지하고 있다. 또한 야간 교통사고 사망자는 3,567명으로 55.9%, 부상자는 168,164명으로 55.4%를 차지하고 있다. 이러한 교통사고는 발생건수에서 2004년 220,755건 대비 2.98%가 감소한 것이며, 야간 교통사고 발생은 전체의 48.8%로서 주야의 비율이 비슷하나 치사율은 야간이 3.4%로 주간 2.6%의 1.3배에 이르고 있다. 야간에 발생하는 교통사고는 운전자의 도로구조 및 부속시설에 대한 충분한 안전시거 확보의 어려움과 교통참가자의 피로와 불충분한 가로조명 그리고 이들 요인간의 부조화 등으로 발생하며, 주간에 비해 피해 정도가 크다는 데 그 심각성이 있다.

In this study, analysis of steel fiber orientation and distribution inside fiber reinforced concrete was performed using micro―CT scanning technology. Samples were extracted from the column according to its height and distance from the mold. Samples were scanned in order to attain the image of steel fibers then region of interest were obtained by binarization process. By calculating the principle moment of inertia of each fiber, direction vector, scale, center postion, volume, and surface area were gained in order to analyze the orientation and distribution. Most of the fibers inside the column tended to be perpendicular to the main axis of the column. Moreover, most of the fibers appeared at the bottom of the column and at the position where it is farthest from the mold.

This research examines whether difference that is some in inclination of combat sports player's sportsmanship is, and accordingly is purposeful to clear relation. combat sports (fencing, Taekwondo, boxing, induction, wrestling, wrestling) player who research target is having player life in middle·high·an university 399 people be . Used Korean-made measure (KMSOS) that Seong-changhun (2003) verifies changing based on Vallerand MSOS by a tool to measure sportsmanship of players. Data processing used SPSS 12.0 programs. Did reliability analysis that use Cronbach'a coefficient to verify believability of an irradiation tool, Difference of sportsmanship used t-test, one-way ANOVA. In this research, drew following conclusion. First, man appeared higher level than woman in wave and human desire, decision respect, and woman appeared higher level than man in victory or defeat excessive fondness. Second, exercise immersion, decision respect, victory or defeat excessive fondness appeared level that minority is taller than majority. Third, in exercise immersion high school player decision respect appear, and tendency of level that middle school playing the first stone is high in victory or defeat excessive fondness appeared. Fourth, striking radical type of player appeared higher level than Geuraepeulring type of player in companion respect factor. Fifth, player less than exercise career 4 years appeared higher level than player less than 7 years and player more than 7 years for victory or defeat excessive fondness factor. Sixth, Taekwondo for best and companion respect factor, high level appeared to boxing item players.
