Following the 2002 World-Cup held in Korea, studies have been actively conducted on plans to utilize all-weather stadiums of fine figures, where large-scale spaces are available for various utilizations. In Japan, dome-type stadiums have been built and are utilizing across the whole nation not only for sports events but also variety of other large-scale events. PTFE(poly tetra fluoro ethylene) is one of the membrane material mainly used for the outer ceiling surface of membrane structures. However, there has not been enough research on the acoustical properties of PTFE membrane material which has been widely used in the multi-purpose stadiums. In this study, air permeability values and sound absorption coefficient of PTFE membrane materials were measured and evaluated in the gymnasium. From the results of measurements of sound absorption coefficient and air permeability of inner membrane materials, it was found that the sound absorption coefficient was good in the air permeability range of $5{\sim}15\;cc/cm^2/s$. Also the relation ship between air permeability and sound absorption coefficient was very high and the sound absorption coefficient was the highest in the range of $6{\sim}9\;cc/cm^2/s$. Secondly, an analysis on the measurements sound absorption characteristics of inner membrane material reveals that the overall sound absorption coefficient was stabilized(higher than 0.5 throughout the whole frequency bands) when the air space behind the membrane material was deeper than 600 mm. When PTFE sound absorptive membrane material was installed in the ceiling of gymnasium, it was confirmed that sound absorptive membrane material can reduce reverberation and increase speech intelligibility in the gymnasium.
기업의 창조적 경영혁신을 위한 디자이너의 동기부여 요인 - 매슬로우(A. H. Maslow)의 욕구단계설 중심으로 -

시장경쟁 환경에서 기술평준화에 따른 차별적 경쟁우위의 한계로 인해 기업의 경영혁신은 창의적 사고와 상상력을 기반으로 새로운 사업 기회를 발굴하고, 시장을 선도하는 핵심가치로 내재화시켜야 한다. 본 연구에서는 기업의 창조적 경영혁신의 일환으로 디자인경영을 통해 창의적인 전문역량을 강화를 논의하였고, 이는 조직 내 디자인 직무의 조직원(디자이너)의 동기부여에서 시발점으로 찾고자 하였다. 디자이너의 동기부여 요인은 매슬로우(A. H. Maslow)의 욕구단계설을 근간으로 각 개별단계를 인간의 기본욕구로 한정하여 실측했으며, 조직소속 여부와 조직규모에 따라 동기부여요인의 차이를 검증하였다. 분석결과로 조직소속 여부에 따라 무소속 집단은 `생리적 욕구`, 소속집단은 `안전욕구`가 높았으며, 소속집단별 규모의 차이에 따른 특이사항으로써 무소속 집단은 상대적으로 `창조적 본능`이 낮았으며, 중소기업 집단은 `자부심, 보람` 욕구가 높았고, 대기업 집단은 생계보장, 신분보장의 `안전욕구`가 높게 측정되었다. 본 연구를 통해 기업의 조직형태에 따른 디자이너의 적합한 동기부여 방안을 발견하고, 이를 바탕으로 창의적인 사고의 전환을 유도함으로써 기업목표 달성과 개인의 욕구를 동시에 만족시켜 창의적이고 유연한 조직문화를 조성할 수 있도록 해야 한다. 또한 앞으로 창의성 발현을 위한 조직 내부의 활성기재 역할로 디자이너의 역할을 재정립하고, 디자인경영을 통해 기업의 차별화된 경쟁우위의 지속성을 달성하는데 제안하고자 한다. The limitation of differentiated competitiveness due to the standardization of technology in a market competition environment, the company`s management innovation must be enhanced by developing a new opportunity based on creative thinking and imagination, and creative performance ability as a core value to lead a market should be internalized This study focuses on creative specialized ability in design management as a means of company`s creative management innovation, and tries to find out a clue to this from the motivation of designers in the organization. The motivation elements of designers are practically measured on the basis of A.H. Maslow`s hierarchy of needs, and the differences of motivation according to whether they belong to an organization or not, and the size of organizations are investigated. As a result, non-belonging group shows a `high physiological needs` while organization belonging group has a high `safety need`. In terms of size, the non belonging group has a low `creative nee`, small sized group shows a `high self esteem` and large sized group is evaluated to have a `high safety need` for living and status security. This study demonstrates that it is important to find out a suitable motivation method for designers according to the forms of organization and to induce creative thinking that leads to a creative and flexible organization culture to achieve not only the company`s goal but also individual`s needs. And reestablishment of the role of designer to boost the creativity in the organization is suggested to maintain the competitiveness of differentiated design management.
