It is a well known that concrete is strong for compression and weak for tension. For reinforcing the weakness and improving the performance about concrete, various methods are used. Fiber reinforced concrete that is one of them has been investigated in this study. The function of fiber in concrete is to improve the stress strain relation and toughness, crack control. It’s applied from normal strength concrete to ultra-high performance concrete. But it is essential to disperse fiber uniformly and to prevent aggregation of fiber in concrete, in order that fiber reinforced concrete show the sufficient performance. The various properties of fiber affect the essential properties, for instance, length and diameter of fiber, source, etc. So, this study evaluated the ultra-high performance concrete with mixed in composite fiber.

Participating in corporate exhibitions has become an important marketing strategy for companies. By participating in exhibitions, companies can effectively introduce their products or services, engage in marketing activities, enhance brand awareness, and seize opportunities to acquire new customers. This paper examines the impact of corporate design exhibition participation on brand awareness enhancement. Firstly, the paper explores the concept and significance of exhibitions and analyzes the benefits that companies can gain from them. Secondly, it focuses on successful design exhibition cases and conducts surveys to derive results regarding consumers' brand awareness, product satisfaction, booth experience satisfaction, and other influencing factors. This provides an opportunity to improve and enhance product design planning and marketing strategies. Finally, based on the analysis of corporate cases and survey results, this paper suggests the direction of product design and marketing strategy formulation, as well as future research tasks that need to be addressed. It is expected that this paper will expand as an important study that helps identify consumer demands and needs at design exhibitions, and improves product design and marketing strategies. 기업의 박람회 참가는 현재 기업들이 다양한 마케팅 전략 중에 하나로 선택하는 중요한 수단이 된다. 기업은 박람회에 참가함으로써 제품이나 서비스를 소개하고 마케팅 활동을 효과적으로 수행할 수 있으며, 이를 통해 브랜드 인식을 향상시키고 새로운 고객을 확보하는 기회를 얻을 수 있다. 본 논문은 기업의 디자인 박람회 참가 사례를 통해서 브랜드 인식 제고에 미치는 영향에 대해 다루고 있다. 첫째, 본 논문에서는 박람회의 개념과 중요성을 살펴보고, 이를 통해 기업이 얻을 수 있는 이점들에 대해 분석하였다. 둘째, 성공적인 디자인 전시회 사례를 중심으로 분석을 하고, 소비자들의 브랜드 인식과 제품 만족도, 부스체험 만족도 등 주변 영향 요인을 설문조사를 통해 결과를 도출하였다. 이를 통해 제품의 디자인 기획과 마케팅 전략을 보완하고 개선할 수 있는 기회로 삼을 수 있다. 마지막으로, 본 논문은 기업 사례 분석과 설문 조사 결과를 통해 얻은 인사이트를 기반으로 제품의 디자인, 마케팅 전략 수립의 방향성 및 앞으로 보완 연구해야 될 과제에 대해 제언하고자 했다. 향후 본 논문은 디자인 박람회에서 소비자의 요구와 필요를 파악하고 제품 디자인 및 마케팅 전략에 반영되고 개선하는 데 도움을 주는 중요한 연구로 확장될 것을 기대한다

The purpose of this study was to evaluate the effects of oral habits on the muscles of mastication and facial expression by means of two parameters: muscle stiffness and elasticity. 10 healthy, fully-dentate male subjects in their twenties were selected for this study; all had normal Class I occlusal relationships. Muscle stiffness and elasticity were measured with a tactile sensor(Venustron, Axiom Co., JAPAN) while subjects were asked to relax and perform various parafunctional activities such unilateral clenching(biting the bite force recorder with a force of 50kg on each subject's preferred side), jaw thrusting and lip bracing. The following muscles were examined: temporalis anterior(Ta), masseter(Mm), frontalis(Fr), inferior orbicularis oculi(OOci), zygomaticus major(Zm), superior and inferior orbularis oris(OOrs and OOri) and mentalis(Mn). Paired t-test, Correlation Coefficients, ANOVA and Multiple Comparison t-tests were used for statistical analysis. Unilateral clenching was highly correlated with bilateral stiffness and elasticity of all the muscles tested. Mm was affected by all three oral habits; Ta was affected by unilateral clenching(p<0.05); Zm was affected by unilateral clenching and OOrs, OOri and Mn were most affected by lip bracing(p<0.05). This study indicates that not only the masticatory muscles but also the muscles of facial expression, mainly circumoral muscles, can be significantly influenced by parafunctional activities such as unilateral clenching and lip bracing.
