A systematic procedure to evaluate fatigue damages and to predict remaining fatigue lives is introduced for a steel railway bridge. Fatigue damages are evaluated by using the currently available fatigue damage theory. Fatigue lives with the condition of fatigue crack initiation are estimated by the probabilistic approach based on the reliability theory as well as the simplified procedure. A equivalent deterministic procedure is also suggested to assess the remaining fatigue life under various traffic conditions. Numerical simulations are used to assess dynamic stress histories with correction factors. Loading models are obtained from the passenger volume data. Train coincidences are also considered. Based on the results, the fatigue life is found to be underestimated by without considering the coincidence of trains on the bridge. The simplified method proposed in this study are found to yield approximately the same results as the systematic procedure.

The nature of supervision is to improve the quality of school education by assisting the teaching activities of teachers and development of a learning community. The school library should be considered a classroom, and should offer library-assisted instruction and information literacy through collaboration between the teacher librarian and subject teachers. Therefore, it should be under the systematic and settled supervision of school library experts. However, analysis shows school library-related divisions have carried out administrative supports in the 16 city and provincial education offices. It is necessary to seek a new supervision system in order to develop and support the education of teacher librarians and the educational value of school libraries. This study suggests The Reading and Library Section which integrates reading in school and public libraries as an independent division in municipal and provincial offices of education.

In the past, 'Samcheong-Dong'(三淸洞) was the most beautiful place in Seoul. So this place appealed to everyone. Regardless of their position, people of all age and both sexes wanted to go Samcheong-Dong. And in Samcheong-Dong, the temple of Taoism(道敎) that named Sokeokseou(昭格署) hold ritual to Heaven. Many poets wrote poem about this temple. As a result, Samcheong-Dong has the aura of the sacred mood. Because of the breathtaking landscapes, many people meet in Samcheong-Dong, and hold the poetry club. Not only the upper ten, but also the middle class people composed poems and published many books of poem. The image of Samcheng-Dong that our contemporaries must remember is the next three distinctive qualities. In the first, the Korean unique temple of Taoism was located in Samcheong-Dong. Secondly, the house of royal family and the upper ten was adjacent to Samcheong-Dong, so this place has the aura of high culture. Thirdly, many poem was created in Samcheong-Dong, so this place leave a masterpiece of middle class that will go down in literary history.

Taoism is very political orientation from the start have. Internal alchemy has several factions, but southern school and northern school of taoism is typical of this. southern school begun from Zhang Bo-duan in north Song dynasty. Northern school is under Jin dynasty rule by Wang Chung-yang been established. Southern school did not create the platform, but northern school is developed mainly by the denomination from the first. Taoism is basically seek eternal life. Internal alchemy was created a unique discipline to reach the such stage with only Internal alchemy. Southern school's training methods were an elaborate series of logical structure with a counterpart, but northern school's methods is somewhat lacking logically. Southern school claim a training methods from the physical to mental through how to achieve it's ultimate goals, northern school took from mental to spiritual retreat methods that the way to achieve objectives. But northern school's theory of ascetic Practice is difficult to see that the contents are pure. Also, the labours of penance during his training process is the other way with Southern school. These differences are they closely associated with Confucianism and Buddhism, to understand the point of view. Southern school put a primary objective in the personal Practice, while northern school is fundamental to the relief of the people. This can see that has how long life times in southern school and northern school's main members. Because the members of southern school enjoyed great longevity, but northern school's main members was not enjoyed longevity. As a result, the southern school's flow is cut off and northern school became the center form a major organization in the history of china taoism. The southern school assimilated to the northern school. In a pure sense, host and guest's changed.

The main contents of Baopuzi inner chapters becomes the basis for the claim "to be achieved Xian the way people can be" named and Shenxian theory that is deployed in the center of the universe body theory with a focus on Xuan and YI and Tao and a problem of "demonstration of Shenxian exist", or ancient science that describes the Chinese alchemy and Taoism spell in other words, inner chapters are writing and how to get prescription way of Shenxian, of medicine to become a predecessors, elephant of some of the changes in the ghost apparition, the longevity, how to avoid the epidemic out of the evil. Inner chapters are presented a regimen thought, the rationale for its mystical religion and philosophy of Monasticism ship on the basis of the theory Shenxian so. Baopuzi Inner chapters is presented in detail how to reach a comprehensive and realistic Shenxian long life in prison without the pre-Qin dynasty Taoism and Qinhan dynasty and times across the Weijin dynasty Shenxian ideas. And is presented in a typical Waidan and Neidan Taoism exercise this system and that in Taoism (Regimen) Thought the important position. Thought of Regimen is very important right information Inner chapters which constitutes the establishment of an important theoretical basis Shenxian Taoism of Gehong this research right in that you can see at a glance the thought of Regimen of Inner chapters is the desperate need for this requirement. It aims to illuminate the entire look of Regimen ever appeared immediately in Inner chapters this paper. After the analysis of the body Tao theory, The theory of the body and the spirit, The theory of Xingming, The theory of Shenxian theoretical foundations of thought appeared in Inner chapters Based on this, the first one conducted regulating the qi flowing in the channels method, Daoyin method, Pranayama, Closed breath, I saw one at the specifics of regimen method such, art of controlling and swallowing breath from the mouth, Convinced, Tuna breathing, Sishenshouyi method, Jinehuandan method, Fangzhongshu. And reporting features found Inner chaptersfinally saw the spirit of Regimen weigh its value.

Various studies have been conducted to evaluate the probabilistic fatigue life of steel railway bridges, but many of them are based on a relatively simple model of crack propagation. The model assumes zero minimum stress and constant loading amplitude, which is not appropriate for the fatigue life evaluation of railway bridges. Thus, this study proposes a new probabilistic method employing an advanced crack propagation model that considers the live-dead load ratio for the fatigue life evaluation of steel railway bridges. In addition, by using the rainflow cycle counting algorithm, it can handle variable-amplitude loading, which is the most common loading pattern for railway bridges. To demonstrate the proposed method, it was applied to a numerical example of a steel railway bridge, and the fatigue lives of the major components and structural system were estimated. Furthermore, the effects of various ratios of live-dead loads on bridge fatigue life were examined through a parametric study. As a result, with the increasing live-dead stress ratio from 0 to 5/6, the fatigue lives can be reduced by approximately 30 years at both the component and system levels.

경기도교육청은 주택법에 따라 앞으로 학교 지을 땅을 살 계획을 세우지 않고 추진하는 아파트 등의 개발 사업을 동의해주지 않기로 했다. 이 방침대로 도교육청이 공동 주택 건설 사업에 대한 혐의 요청을 거부할 경우 새로운 대규모 아파트 건설 사업 추진이 사실상 중단될 수 밖에 없다. 학교 용지 매입비에 대해 살펴본다
