Recommendations for older driver-friendly automobile interior design have been determined by taking into account older people's physical and cognitive characteristics. Twenty three older people (aged from 54 to 78) and five younger people (from 20 to 29) performed several tasks in actual driving conditions, in which their reaction times and performance errors were recorded. Some design factors were found to be related to older drivers' visibility and controllability. Several design recommendations were proposed in terms of cluster color and font, display location, and HVAC control type. Proposed recommendations are expected to satisfy a wider range of older drivers as these will facilitate automobile interior designs which are fitter to older drivers' visual, cognitive, and manual capabilities.

현재 급변하는 환경 속에서 각 국가는 일자리 창출 및 기술 경쟁력 강화를 위한 노력을 지속하고 있다. 특히 벤처기업 및 창업기업에 대한 지원과 활성화 정책은 국가 경쟁력을 높이는 역할을 하는 것으로 알려져 있다. 경쟁 심화로 비즈니스 수명이 짧아지고 고객들의 요구가 다양화되는 환경의 불확실성이 확대되는 가운데 기업은 적절한 대처를 해야 한다. 우선 기업은 스스로 내부 역량을 강화하는 노력을 하는 것이 중요하다. 그러나 벤처기업은 내부 자원 및 역량 등이 부족하여 외부 환경으로부터의 지원이 기업의 생존으로 연결될 만큼 중요하다고 볼 수 있다(Timmons, 1994). 기업의 경쟁력 강화를 위해 국가 차원에서 재정지원 및 인증제도를 운용하고 있다. 그러나 재정지원은 상황에 따라 기업의 자생력을 낮출 수 있으므로 연구개발 지원 및 창업교육과 같은 비 재정적 지원이 벤처기업 성장에 장기적으로 도움이 된다고 보았다(Aghion et al., 2012; 전미미·고강혁, 2021). 비 재정적 지원은 사업화, 시설, 공간, 보육, 인력, 인증제도 등으로 구분되는데 본 연구에서는 인증제도인 벤처기업 확인제도의 혜택을 중심으로 확인하였다. 이를 위해 2021년도 벤처기업정밀실태조사 데이터 및 벤처기업의 매출액 데이터를 활용하였으며, SPSS 26.0 패키지와 SPSS PROCESS MACRO를 활용하여 분석하였다. 분석 결과, 벤처기업의 경영환경 수준은 벤처확인제도 혜택이나 벤처기업 역량 수준을 높이는 데는 긍정적인 영향을 주지만, 실질적인 경영성과로 이어지기는 어려운 것으로 확인되었다. 또한 벤처기업의 경영환경 수준과 경영성과 간 관계를 벤처기업 역량 수준이 매개하는 것으로 확인되었다. 결과적으로 단순히 벤처기업의 경영환경 수준이 긍정적이거나 벤처기업에 친화적일지라도 외부 환경으로부터의 지원을 잘 소화할 수 있는 내부 역량이 있는 기업이 경영성과를 높인다고 할 수 있다.

The purpose of this study was to find out criteria for classifying fashion brand from the viewpoint of fashion business practice in order to develop strategy of fashion brands and to manage brand effectively and systematically, and to suggest theoretical frame for application of these criteria. Survey was implemented for this research. 388 Data from the people who works for merchandising, sales or design in fashion business company was analyzed. Questionnaires were developed based on 37 fashion brand classification criteria. SPSS package and LISREL program were used to analyze data. Factor analysis, one-way ANOVA, $$\mu$tiple response analysis, correlation analysis, and structure equation model analysis were applied. The results of this study were as follows First, factor analysis considering 37 classification criteria identified 7 factors as classification criteria which can be used effectively by fashion business company. Second, in two cases, based on the job description and the responsible items, analysis showed that importance of the 7 classification criteria factors was different. And all of 7 criteria were correlated to each other. Third, the effective method to classify fashion brands was proposed by establishing the model of the relationship among the values of 7 criteria and by proving it by the structure equation model analysis. And the two types of the courses to classify fashion brand were shown. Forth, according to the evaluation of these criteria in the importance of appropriateness and difficulty of implementing, classification criteria factor of "the level of product concept" was found to be very effective and "the level of brand value" was ineffective to apply.

Low frequency noises(up to about 200 Hz) such as booming are mainly caused by particular modes, and in general the solutions may be found based on mode controls where conventional methods such as FEM can be used. However, at higher frequencies between 0.3~1 kHz, as the number of modes rapidly increases, radiation characteristics from structures, performances of damping sheets and sound packages may be more crucial rather than particular modes, and consequently the conventional FEM may be less practical in dealing with this kinds of structure-borne problems. In this context, so-called 'mid-frequency simulation model' based on FE-SEA hybrid method is studied and validated to reduce noise in this frequency region. Energy transmission loss(i.e. air borne noise) is also studied. A dash panel component is chosen for this study, which is an important path that transmits both structure-borne and air borne energies into the cavity. Design modifications including structural modifications, attachment of damping sheets and application of different sound packages are taken into account and the corresponding noise characteristics are experimentally identified. It is found that the dash member behaves as a noise path. The damping sheet and sound packages have similar influences on both sound radiation and transmission loss. The comparison between experiments and simulations shows that this model could be used to predict the tendency of noise improvement.
