Recently, hydraulic motor is getting the spotlight. It is resulted from rapid civil engineering public works by a lot of developing countries around the world. In this study, we divided the valves which are affixed in the hydraulic motor into some parts, implemented them through computer simulation, verified validation of each component, and analyzed behavior adding driving condition. Through the analyzed results with general driving condition, we found the reason why behavior became unstable as the motor had started spinning. Through the analyzed results with tough driving condition, we verified that the valve works well with it's production purpose.

Several possibilities on the stability analysis of the railroad tunnels passing through the abandoned mining area are considered in this paper. Previous works on the influence zone due to cavities are investigated to study the effect of the safety deterioration near the cavities which are normally unknown to the engineers. Additional works on the numerical analysis of the influential zone are also performed in 3D space. The praximity of railroad tunnel and unexpected cavities is critical to influence the stability of railroad tunnel under construction. Futhermore, the study on the influence of underground condition like joint and faults should be significantly controlled under both design and construction stage.

During excavation works for underground facilities, temporary tieback wall with earth anchor system was investigated for safety's sake. An excavation 9.7 meter deep was monitored by slope inclinometer in twelve measuring points. Instrumented lateral displacements of the wall during 177 days are represented. Especially, lateral displacements of the two positions under completely different condition are compared to investigate the effect of backfilling between soldier pile and the soil behind wall. The deformation behaviors of the wall according to both depth and elasped time are discussed. Finally, a numerical analysis by the program FLAC was performed, and calculated displacements are compared to measured ones.

Railway accident analysis results show that accidents cased by human factors are not decreasing, whereas H/W related accidents are steadily decreasing. For the efficient management of human factors, many expertise on design, conditions, safety culture and staffing are required. But current safety management activities on safety critical works are focused on training, due to the limited resource and information. In order to establish railway human factors management requirements, human factors management status on all train operating companies are analysed in this study.

This article reviewed ‘Gojangsijoseonju(고장시조선주)' which was written by Gojeong-ok(.고정옥), a scholar of Korean literature. and showed the features and importance in the history of Korean literature. Gojeong-ok was not properly studied in the history of Korean literature for the time being because he went to North Korea during the Korean war. Even for the researcher on Korean literature.' the literary works of Gojeong-ok were not introduced properly. However, the systematic studies on Gojeong-ok and his literary works should be done, and should be well appreciate his work in the history of the research for Korean literature by his achievements. This article considered his literary achievement through his book, 'Gojangsijoseonju'. 'Jangsijo(장시조), that was named by Gojeong-ok for 'Saseolsijo(사설시조), stood in highly important position to explain the history of literarature in late period of Chosun(조선) Dynasty. He tried the analysis on the fifty (50) selected 'Saseolsijo' and made commentaries on them in his book. And he suggested the original and creative theory on 'Saseolsijo' at the time of the book published. This article considered his understandings on the poems of classical literature, revealed in his literary works, and especially, the features on the theory for the 'Jangsijo'. Through this process, it could be clearly understand his views on literary works in itself. By considering the analysis of literature that was introduced with the commentaries, it could be seen the aspects of the specific analysis on each literature. Through these works, it could be looked forward to getting more detailed investigating clue on the view of Gojeong-ok for the poems of classical literature.

The warranty liability period for defects in apartment buildings by work type is not based on scientific analysis, making the appropriateness of the term a culprit behind the lawsuits. Therefore, this research aims to evaluate the appropriateness of the warranty liability term of apartment buildings by identifying the current status of defects, in particular, caused by finishing works. That is because the number of defects, caused during the finishing works, accounted for the largest portion of the total defect cases of apartment buildings reported to the Apartment Defect Dispute Mediation Committee under the Ministry of Land, Infrastructure, and Transport of Korea between 2010 and 2011. The result from analyzing claims for defect repairs of the finishing works showed that most cases by work type continued to be made after two years, and only about 60% were charged within the warranty period. And, defects by work type have correlation, which needs to be considered for a better construction technique. Considering a low correlation between the possibility of defects and the construction performance rankings, which are highly relevant to the apartment preference. It is believed that there needs to be a qualification process for agencies that actually performs finishing works.

This study assessed the reliability of the agricultural water supply based on future climate change scenarios, and suggested plans to improve the reliability in order to promote the adaptability of irrigation water in agricultural reservoirs to climate change. The assessment of agricultural water supply reliability was performed on reservoirs which had a lower water quantity than their design basis and which had recently been subject to drought. In other words, from the irrigation districts of main intake works among the reservoirs managed by the Korea Rural Community Corporation, 1~2 districts in each province-that is, a total of 13 districts -that were recently designated as a district for securing agricultural water (drought prevention district) were selected. Climate change scenarios were applied to the selected districts to analyze their future water supply reliability compared to the current level. All districts selected showed a drought frequency of 4 years or shorter, which demonstrated the need to establish climate change response plans. As plans for responding to climate change, a plan that utilizes supplemental intake works to reduce the area of the irrigation districts of main intake works, and another one that increases the capacity of main intake works were adopted to reanalyze their water supply reliability. When the area of the irrigation districts of main intake works was reduced by about 30~40%, the drought frequency dropped to more than 10 years, securing the reliability of water supply. To secure the reliability by increasing the capacity of main intake works, it was calculated that about 19,000~2,400,000 tons need to be added to each reservoir. In addition, climate change response plans were suggested to improve the reliability of the water supply in each district based on the results of economic analysis.

This Study is a thesis presenting handicrafty and decorative textile design as well as sensual fashion design through the works of Gustav Klimt. The result is as below; The formative qualities in the works of Klimt could be featured as decorativeness, sensuality and symbolism. First, the decorative inclination is prominent in the portrait and the effect is maximized with the golden mosaic shape expressed on the dress and the background influenced by the Byzantine. Second, the sensuality could be recognized directly from the women's pose or facial expression in the works of Klimt, otherwise appeared on the refined expression showed on the portraits of noble lady Third, to surpass the reality, Klimt preferred the symbolic expression, which can be shown on the patterns in the works addressing the themes such as the legends and myths, or figures of men and women expressed with the image of an abstract features of membrum. The development of the textile design is as fellowed. First, it analyzes and reconstitutes the formativeness and the element of design in the works of Klimt by the flow of the form factor. Second. it makes a pattern of a single nature through perception, analysis, description and drawing and expresses with realization of the characteristics of Klimt. Focusing on the handicrafts and decorativeness out of the latest trends and making the most use of the sensuality, the designed textiles were completed by the handicrafty techniques, used in the fashion design and completed as the design of sensual images. The textile development aims at minimizing the limit of design that can be caused by the absence of silhouette and detail, expanding the range of its creativity of fashion designs and creating fashion design high value-added.
