Other comments on matters satisfaction survey through questionnaires typically measure by frequency analysis method is performed, the short answer for how to apply. These satisfaction surveys, however, because of the environment and atmosphere of its target at the time of the survey, personal psychological state, depending on the scale of change in business or policy of customer satisfaction feedback, there is a problem. This survey results, tangible results in terms of the feasibility of the business and policy indirectly as a result, which has been used as a material fact is. New survey method is show how the business and policy objectives than can be reflected positively in the present study, and comparing these surveys in a variety of ways for the analytical method proposed by KANO, Timko results suggested. Should be an ongoing investigation, and different survey methods for the study on the same sample the actual observed by comparing the results for the superiority of the new results presented.

This study investigates the delay declaration of the traffic insurance accident which is focused on a business truck causing the traffic insurance accident. The type of the delay declaration is classified as 15 types and it differs in level of payment of insurance money. It is most important that the support policy of government and the self-help of related business to reduce the delay declaration and pursue progressive solution. Moreover, it is essential not only introducing the strict regulation system but also adapting the various victim protection system.

The purpose of this study is to use organisms or micro-organism functions for eco-friendly water-purification according to concentration in porous concrete using EM, utilizing bioremediation.

In this study, fire test of predicting fire behavior(fire growth rate, temperature of compartment, etc.) were performed for fire safety diagnosis in buildings. From this test, fire propagation for each combustible was identified, which was delayed compared to the summed heat release rate fo a single combustible. Also, comparison with Matsuyama model allowed improvement in the modeling of the process of fire spreading to nearby combustibles

This study investigated the House of Commons through the combustion characteristics of the flammable after performing the experiment for predicting fire constellation is to present basic material. Combustibles of the House of Commons was established to investigate through the standard model, such a list of proposed standards for the combustible

Korea rapidly arranged urbanization and overpopulation with high growth of economy and all kinds of decrepit facilities are scattered all over the downtown. If there is a strong wind in fire, fire is rapidly increased by various fire spread factors. And Korea cannot build prediction model of urban fire combustion phenomena because there is no studies that physically explains the suitable flame phenomena for its real state. In this study, based on the Japanese Urban fire simulation to target the dense building and suitability of fire risk assessment were reviewed

본 논문에서는 FR-ECC의 수축특성과 균열도입 전후의 내동해성을 평가하였으며, FR-ECC를 활용한 다층복공구조의 지수성능과 박리박락저항성, 또한 FR-ECC로 단면복구 된 보부재의 휨성능을 평가하였다. 그 결과, FR-ECC는 소성수축에 의한 균열 및 건조수축에 의한 길이변화율이 기존의 보수모르터에 비해 크게 저감되었으며, 구속상태에서의 건조수축에 대한 균열저항성이 개선됨을 알 수 있었다. 또한, FR-ECC는 내동해성이 매우 우수하였으며, 균열도입 후에도 동결융해작용에 의한 인장성능의 저하는 확인되지 않았다. 한편, FR-ECC로 보수된 휨부재는 초기균열모멘트, 항복모멘트 및 극한모멘트 등의 휨성능이 증대되었으며, 멀티플크랙 특성에 의해 휨파괴시까지 균열폭을 안정적으로 제어할 수 있었다.

본 연구에서는 RC구조물의 내구 및 내화성능을 동시에 향상시킬 수 있는 고인성 모르타르 (FR-ECC)를 개발하여, 이를 RC구조물의 보수재료로서 사용하기 위한 실험적 연구를 실시하였다. 즉, FR-ECC를 이용하여 제조한 콘크리트 시험체의 강도, 열적특성, 모의부재의 철근부식특성, 내화성능 등에 대하여 검토하였으며, FR-ECC의 현장적용 가능성에 대해서도 평가하였다. 그 결과, FR-ECC는 기존 보수 모르타르에 비해 우수한 강도 및 내구성능을 보유하고, 휨균열 발생 후에도 외부열화 인자의 침입을 억제하여 철근부식을 방지하는 것으로 나타났다. 또한 FR-ECC를 적용한 부재는 ISO 834 가열조건에서도 우수한 내화성능을 갖는 것으로 나타났으며, 뿜칠성능 등의 현장시공 성능에서도 우수한 특성을 나타냈다.

기존 연구에서 살펴보면, 철근콘크리트구조물에 발생한 화재로 인해 경화된 시멘트 페이스트와 골재의 수축과 팽창의 차이에 따라 조직이 와해되고, 열응력에 의해 균열이 발생하여 내구성이 저하한다. 그래서 성능저하의 정확한 진단은 일반적인 콘크리트구조물에서 방화성능저하의 매커니즘에 관한 기초가 요구되며, 고온에 노출된 콘크리트의 특성에 대한 기초 정보와 데이터는 성능저하의 정확한 진단을 위해 필요하다. 따라서, 본 연구는 다양한 콘크리트 시험체를 제작하여, 고온 환경에서 노출시켜, 폭열을 관찰하고, 공학적인 특성을 평가함으로서 화재피해를 입은 콘크리트구조물 성능저하의 빠르고 정확한 진단을 위한 기초적인 데이터를 제공하고자 한다.
