Among the factors of consumer preference, aesthetics has been importantly considered in competitive market environment. Generally, consumers' purchasing standard is influenced as their awareness increases relative to variations in their lifestyles and due to these changes in consumers' wishes, design techniques and methods are focused towards adapting to these changes. Thus, in order to satisfy consumers' needs, and markets characterized with the short durability cycle of products, a distinctive design should be developed with respect to the form of products. The proposed design should also support form as an important factor to attract consumers preference. This study attempts to understand typology based on a categorization theory, and the conceptual structure of aesthetics. Both are importantly considered simultaneously. In addition, the study proposes a new design process by extracting Rhythm affecting aesthetic. In conclusion, the result of this study aims at developing more consumer preferring design beyond the scope of the ordinary designer's idea and generation.

자동차에서 실내음질은 구매결정 요소들 중의 하나로 그 중요성이 점차 증가하고 있다. 따라서 다양한 운전조건에서 운전자가 기대하는 실내음질의 기대 수준을 충족시켜야 한다. 소비자는 운전경험과 습관에 따라 기대하는 음질에 차이가 있고 소리에 대한 표현방식도 모호하기 때문에 이러한 주관적 특성을 하나의 통일된 표현으로 정의 하기가 어렵다. 그러나 지난 이십여 년 동안의 음질개발과 차량 실내소음 주관평가의 통계처리로 통일된 표현을 할 수 있었다. 나아가 심리음향학 및 신호처리기술의 발달과 꾸준한 음질연구결과로 소리특성을 객관적으로 나타내는 소리의 시각화가 가능하였으며, 운전자가 인식하는 주관평가와의 상관관계를 높여 차량의 대표적인 음질인자로 정량화하여 음질목표를 설정할 수 있었다. 실내소음의 구성은 엔진 투과음, 흡배기 소음, 바람 소음, 도로 기인 소음 등으로 다양하므로 소음원에 따라 음의 균형을 맞추어 조화로운 음질개발을 하는 것이 중요했다. 또한 차량 판매되는 지역에 따라 선호음이 상이하여 지역별 실내음질의 차별화가 필요했다. 궁극적으로는 운전자의 감성품질을 만족할 수 있도록 음을 제어하여 브랜드 사운드를 개발하고 있다. 이러한 실내음질을 달성하기 위한 방법으로 소음원과 전달경로에 대해 기여도를 분석하고, 경로를 구성하는 시스템 별로 세분화하여 시스템 목표를 설정하였다. 시스템 개발에 중요한 인자로 차량의 동강성 및 흡차음 성능을 들 수 있다. 특히 디젤차량의 비중이 큰 유럽업체의 차량의 동강성 및 흡차음 개발 능력은 높게 평가되고 있다. 이에 유럽의 부품전문회사가 가지고 있는 해석과 시험적인 개발 방법을 통하여 전달계 특성을 만족하기 위한 시스템의 동강성 및 흡차음 특성을 개발하고 있다. 차량음질 튜닝의 중요한 기법 중 하나로 흡배기 개발을 추진하고 있다. 친환경자동차인 하이브리드차량, 전기차량 및 연료전지차량의 경우 전기구동부품에서 발생하는 각종 이음 발생을 최소화 했다. 보행자를 보호하고 운전의 즐거움을 향상하기 위한 가상사운드 개발을 진행하고 있다. 회사 수익성 향상을 위한 원가절감 및 구조 경량화에 따른 음질악화와 연비 향상 및 배기가스 규제 강화로 고성능 고출력 엔진탑재에 따른 음질악화 요인을 극복해야 했다. 운전자의 청감은 차량의 운전성에 따라서도 크게 영향을 받게 되므로 엔진제어와 변속기제어를 통해 음질과 운전성이 조화를 이룰 수 있도록 개발하고 있다. 향후, 소음원에 따른 시스템 최적화 개발, 운전성과 음질 연계 개발과 친환경차량의 가상사운드 개발 등이 자동차 음질 개발의 중요한 이슈로 생각한다.

In the underwater acoustic communication channels, multipath reflection become the cause of obstacle. Generally, equalizer has been applied to overcome these problems. In this paper, the method was proposed to optimize tap-length of decision feedback equalizer using genetic algorithm. After inputting feed-forward filter length and feed-back filter length as genetic information of the genetic algorithm, it optimize tap-length using BER(bit error rate) calculation in accordance with object function. The object function consist of decision feedback equalizer and BER calculation. For the purpose of BER calculation in the object function, the method was proposed to optimize the tap-length of decision feedback equalizer with genetic algorithm using preamble signals. As a result of experiments, the optimized BER is 0.0355 for signals which were received through a 25m receiver and which were applied to calculate BER merely using preamble signals in object function. When all data were used to calculate BER in object function, the optimized BER is 0.0215.

It is said that the highlight in the media covergence and integration within digital environment era is 'Contents'. Due to the advent of new media and various covergence and integration services, the competition between the platforms has become aggressive. As a result, it is predicted that the negotiation power of a 'Content's industry will be strengthened. In reality, the actual environmental changes in the media environment have accompanied elements of industrial crisis rather than opportunity to expand the market. The changes are especially causing sales structure distortion and proceeds deterioration in the Korean film industry. Moreover, telecommunication and broadcasting businesses are making their entrance into the film industry, through the appearance of the media covergence and integration as a backdrop. Thus, the situation that the Korean film industry is facing is closely associated with the development of the digital technology and new media environment. Eventually, weathering the crisis and pioneering the future will be possible through changes in the media environment. The purpose of this study is to show how the media covergence and integration phenomenon is occurring in the film industry. This study will also focus on what new problems are occurring as a result, and seek out the solutions that are available.

It can be said that Italian designs are unrestrained, aesthetic and art for arts sake, and they come to stylize their character based on geographical features, racial traits and culture. The Italian architects work for the reconstruction of their devastated country and spare no pains to produce competitive goods on international markets since the second wend war. In spite of a inherent scarcity of resources, Italian furniture is the product of mixture of aesthetic material and new material with creative gifts. A lot of companies succeed in finding and training capable designers and devote themselves to modem furniture industry. As a result, Italy becomes one of the worlds most eminent furniture industrial countries now. And the fame is owed to Italy's national awareness of the importance of the matter and endeavor without sparing systematic support. This research is to find out which factors have an influence on the progress of furniture design in Italy and to analyze how these factors build up formative arts combining with historical background in Italy. Moreover, this research suggests how to make contributions to the cause of furniture design growth when considering our geographical features, racial characteristics, culture and industrial circumstances, by analyzing the process of development and strategy in Italian design industry.

Researchers are persons who are destined to produce improved knowledge, with duty, responsibility and desire for overcoming limits of the existing knowledge in continuously changing natural and social environments. In addition, both drawing research outcomes 'contributing to the society' by tapping on 'researches convergent with other disciplines', to 'deducing meaningful research outcomes' and 'operating laboratories for fostering convergence talents', for the consistency of incessant researches are the momentum for convergence researchers to continue convergence researches. However, an irony fact is that 53.1% of convergence researchers respond that they began convergence researches from happenstantial momentum (a happenstantial talk with other majors)'. This study examined what was the momentum from which convergence researches began and what was the motive with which they have been consistently conducted and suggested how to continue convergence researches.

There have been various researches on the relationship between a company's R&D investment and the outcome from innovation. However, these studies failed to effectively analyze the decision-making process followed by companies in relation to knowledge production. Especially, in analyzing the patent of companies, the Poisson model has been commonly used, but its limitations have been pointed out. In recent years, many studies have adopted negative binomial models, but they still pose limitations in analyzing the selection process. This paper proposed a hurdle negative binomial model to effectively reflect the company's decision embedded within patent information and conduct an empirical analysis on a survey of businesses' activities. In particular, the study analyzed the selection process of companies in determining the number of patents. As a result of estimation, the presence of over-dispersion was identified. In addition, the Wald-test confirmed that setting up of hurdles was valid, and there was a difference between the results of hurdle models and those of general negative binomial settings.
