Explosives demolition mothod is allowed for more efficient time-saving and safer demolitioni operations as compared to conventional / mechanical demolition methods. CDI has to minimize the effects of noise, dust and various demolition hazards to the public areas, and residences that are located adjacent to the project site. CDI's explosives demolition work on the Nam san Foreigner's Apartment Complex and chosun trading Co's factory are backed by over 45 years of explosives experience in the demolition of over 6,000 structures worldwide, many of these structures are similar to the Nam san Foreigner's Apt. and Chosun trading's factory in construction and proximity to sensitive adjacent exposures. Recoginized worldwide as the founder of the leader in explosives demolitioni technology, CDI always will applied "State-of-the-Art" explosives techniques to safely and successfully achieve the desired demolition results on these project. CDI has never injured, much less caused any fatality, to either a worker on one of our sites or to a third party during the implosion of high-rise structure.

In the early of Joseon Dynasty, Royal Tomb developed from stone chamber tomb to lime chamber tomb through precedents. The lime chamber tomb consists of main-chamber(JeongGwang) and sub-chamber(ToeGwang). This separation makes character to construct tumulus of the Royal Tomb half and half. By this character, the Royal Tomb are not constructed by separate structure but constructed by coadjustment. The underground structure and tumulus of the Royal Tomb affect each other in the size and method of construction. The selecting type of Royal Tomb is generally made decision through terrain and politics. This study prove the architectural structure is also one of the major cause the that select type of Royal Tomb.

Purpose: The present study purposed to investigate and analyze domestic websites providing information about dementia and to suggest future directions for the development of dementia-related websites. Mothod: For this purpose, the researcher selected 13 domestic websites that were available in November and December 2004, and evaluated them in terms of construction, operation, accessibility and contents on a scale 4 point (0$\~$3). Result: The construction of dementia-related websites got 6$\~$13 out of 18 points, which suggests that management policies for the operation of dementia-related web sites are inadequate. The operation of dementia-related web sites got 7$\~$15 out of 24 points. In particular, all 13 sites got a low score in the aspect of continuance. With regard to accessibility, the sites were evaluated on how easily users could access the sites and they got 2$\~$8 out of 15 points. In evaluating contents, the sites got 9$\~$18 out of 21 points with regard to the purpose and appropriateness of the contents. Conclusion: This shows that most sites did not provide diverse types of dementia-related information. Because it is highly advantageous to perform primary dementia-preventing management through websites, this study proposes to develop a website evaluation system in order to provide high quality dementia-related information.

본 논문은 고장력 인장봉에 의해 보강된 RC보의 휨거동을 평가하기 위한 해석적 방법을 제시하고 있다. 본 연구에 대한 선행 실험결과를 이용하였다. 실험 논문에서는 외부 강봉 보강의 이점에 대해서 소개하고 있다. 휨거동을 평가하기 위해 본 논문은 해석적 방법으로 단순누가산정의 방법을 제시하고 있다. 이 방법은 기본적으로 고장력 인장봉에 의해 보강된 RC보가 받는 전체하중은 강봉이 없는 RC보가 받는 하중과 강봉 자체가 받는 하중의 합과 같다고 가정한 것이다. 추가로 강봉에 의해 발생하는 축력과 강봉에 주어진 프리스트레스트에 대하여 고려를 하였다. 실험 결과와 이론해석의 결과값을 비교하여 단순누가산정 방법은 고장력 인장봉에 의해 보강된 RC보의 비선형 휨거동을 예측함에 있어서 비교적 정확한 상관관계를 보여주고 있다.
