Purpose Five animals sounds which are come under five sounds(Gong, Sang, jiao, zhi, yu) which are compared with the musical scale. It is looking for similarity between five animals' sounds and the musical scale. Methods 녹음 record 1 ig machine 1. Five animals (cattle, horse, pheasant, pig, sheep) sounds has been recording on tape. 2. That was transfer to CSL(computerized speech lab) 3. That was analysed to pitch, formant 1,2,3. energy pitch 4. That analysed result (Pitch, formant 1,2,3. energy ratio) of five animals are calculated and compared with the five musical scale(five sounds) Result The ratio of five animals sounds is not consistent with the musical scale in any five item (pitch, formant 1,2,3. energy). Conclusion 1.The five musical scale has no similarity with the five animals sounds 2.The five sound is supposed to oriented form theoretical back ground of five-going not have no relative with the five animals sounds

New forming technologies are being introduced to automotive manufacturing processes. Among them, a simultaneous forming is one of the innovative forming technologies to be able to reduce production time and cost. Several parts can be simultaneously manufactured by the process, while the conventional stamping demands the same number of die sets with the number of parts. In this study, the automotive rear floor side member was manufactured by the simultaneous forming. The position and the size of initial blank were determined by forming analyses and try-outs, and the blank movement during the forming was controlled by introducing the spotweld.

콘텐츠는 다양한 문화적인 특징을 내포하고 있으며, 어떤 환경이건 그 지역의 문화를 콘텐츠로 하고 있다. 이러한 문화적 콘텐츠는 우리생활에 영향을 끼친다. 본 연구는 부산 해양관광지를 중심으로 해양도시의 자연환경을 활용한 특색 있는 감성 문화 콘텐츠의 발전 가능성에 대해 고찰하고, 해변에서의 여가활동 증진에 새로운 디자인 시스템으로 도움이 되고자 하는 연구이다. 이론적 고찰을 통해 감성문화에 대해 알아보았으며, 감성문화사례를 통해 각 지역의 특색을 느낄 수 있는 '테마길', '지역성이 반영된 스탬프 투어' 등이 있다는 점을 확인할 수 있었다. 추후 과제에서는 부산 해양관광지를 중심으로 현장조사를 통한 분석과정을 이행할 것이며, '길'이라는 테마에 대한 분석과 평가를 통하여, 그에 대응 하는 문화적인 콘텐츠로의 연계방안에 대해 살펴보고자 한다.

ERP 도입 및 운영과정에 전사적 자원 즉 인적자원과 물적자원이 투입되고 활용되었다. 기업경영에 있어서 제 자원의 관리가 중요하고, 특히 인적자원이 성과에 중요한 영향을 미치고 있다. 그 동안 ERP 도입요인과 도입성과에 대한 기존의 연구는 중소기업을 포함한 전체 기업을 대상으로 한 연구가 대부분이었으며, 그러한 연구의 대부분은 먼저 ERP을 도입한 대기업 위주의 연구였다고 볼 수 있다. 중소제조기업의 ERP 도입요인으로서 열악한 전사적 자원의 수준이 ERP 도입성과 즉 생산효율성에 영향을 미친다는 전제하에 이들 간의 인과관계를 위한 연구모형을 제시하였다.

The Re-mi-con sludge water has been investigated because of environmental pollution and disposal cost. So, sludge water is partially reused as mixing water. However, if sludge water is reused too much that would influence the quality of concrete. KS specification limits the amount of sludge content up to 3$\%$ of cement weight. In this study, the effect of re-mi-con sludge on the characteristics of concrete is compared to raise the reuse ratio of re-mi-con sludge. From the test results, as blending ratio of re-mi-con sludge increases, workability is decreases. However, the re-mi-con sludge water have a minor effect on the strength development, the drying shrinkage and the resistance of freeze and thawing. Also, the existing model codes of drying shrinkage do not coincide with the test results of this study.

비대칭 부하 전류를 평형 상태로 만들기 위한 보상장치는 3상변수를 대칭좌표로 분리해야한다. 통상 전대역필터를 이용한 정상분, 역상분 분리 방식이 사용되는데 제어기 최하위단에서 동작하는 전대역필터의 대역폭이 전체 제어시스템의 대역폭을 제한한다. 따라서 보상장치의 제어성능을 향상시키기 위해서는 정역분리에 사용하는 필터의 대역폭을 넓혀야 한다. 본 논문에서는 대역폭이 조절가능한 고속화된 대칭좌표 분리 알고리즘을 제안한다. 이를 MATLAB/SIMULINK를 이용하여 시뮬레이션을 진행하였으며, TMS320F28335를 이용하여 실험을 진행하였다.

On processing of the shipbuilding, Various steel plates are used as the important material in many fields including the shell plate, a structure, etc. Therefore, the proper steel plate management system like a warehousing, pile, delivery is very important. Presently Operators manage the steel plate by using the software program, but they manage many parts manually, so many problems are generated on the steel plate check, management, and operator safety. In order to solve this problem, we developed Auto Steel-Plate Piling System. Also this system automatically manages and traces the steel-plate from warehousing to delivery.

An experience based training system concerning various fire situations which may result many casualties has been required to make rapid decision and improve the responsiveness. Recently, the necessity of virtual reality (VR) based training system which can replace a dangerous full-scale fire training and be easily adopted to the training or evaluation process is increasing. This study constructed tile virtual environment according to pre-defined scenarios, utilized the FDS(Fire Dynamics Simulator), three dimensional computational fire analysis program, to derive numerically simulated data on the propagation of fire. Finally, by visualizing the realistic fire and smoke behavior through virtual reality technique and implementing real-time interaction, we developed a VR-based fire training simulator. Also, in order to ensure the sense for tile real of a virtual world and reaI-time performance at the same time, we proposed appropriate data processing and space search algorithms, demonstrate d the value of proposed method through experiments.

Deicing salt has been generally used for prevention of a road freezing in winter, and the amount is increasing every year. However, deicing salt may induce the decrease of bond strength, surface scaling, and environmental pollution, etc. The purpose of this paper is to suggest the fundamental data on safety and durability for concrete structures through the estimation of characteristics of chloride penetration with deicer types. According to the test results, as age of concrete is increased, chloride penetration depth is also increased independent of deicer types. However, there is no remarkable difference between deicer types. And when the estimation of chloride diffusion is carried out by immersion test, diffusion coefficient is decreased with ages, and short-term estimation may overestimate the coefficient.
