Recently, the rapidly falling birth rates and the development of medical technology is causing social problems, such as the aged society and super-aged society. With the nation’s birthrate the lowest in its history and among fellow OECD member states, South Korea officially became an "aging society(when at least 7 percent of the population is above 65 years of age)"in 1999. Especially, Korean society have been quickly transformed into an super-aging society. The speed of this social change doesn't compare with the speed of develoment of silver industry. The industry of medical functional bed accounts for a great part of silver industry. The medical functional bed affects a lot of the life of the aged. But, the medical functional bed have been developed for not the aged but the medical team and caregiver.  The purpose of this study is to propose the basic information for the medical functional bed design for the aged. So, the characteristics and preference of the aged was investigated and analyzed.  The result of this investigation are as follows.  ① form : simple, ② color : Warm Ivory color,  ③ function : the mattress should be considered. The methods of the medical functional bed design for the aged were suggested in the field of form, color and function. But, it is only basic results. So, more various and specific study sould be come out for silver industry 최근, 우리나라는 급격한 출산률 저하와 의학기술의 발달 등으로 인해, 이미 65세 이상 인구가 전체인구의 7%이상에 해당하는 고령화 사회로 진입했으며, OECD 발표에 따르면 역사상 가장 빠른 속도로 초고령사회를 맞게 될 것으로 예측되고 있다. 이러한 급격한 인구구조의 변화에 비해, 실버산업은 질적으로나 양적으로 미흡한 실정이다. 실버산업 중 노인들의 건강생활에 많은 영향을 미치는 의료용 침대는, 의료행위의 기능성을 위주로 개발되어 있어, 이를 이용하는 노인의 정서적, 심리적 특성은 고려되지 못하고 있다. 따라서, 본 연구에서는 이용자인 노인의 특성을 고려한 노인에게 편리한 의료용 기능성 침대 개발을 위하여, 노인들의 성향을 조사․분석하여, 의료용 기능성침대 디자인을 위한 기초 정보를 제공하는데 그 목적이 있다,디자인의 각 요소별 지향 방향에 대하여 분석한 결과는 다음과 같다. ① 형태는 단순화, 간편화하고, ② 색채는 Warm Ivory Color를 적용하고,③ 기능적인 면으로는 매트리스를 고려하여야 한다. 이상으로서 침대의 기능과 색채, 재료, 노인 측면의 기능성 침대의 디자인에 대한 의견을 설문 등의 현황분석을 통해 제시하였으며, 향후 보다 구체적인 연구를 통해 디자인의 다양화를 모색하므로 고령사회의 실버산업육성을 유도해야 할 것이다.

이영대,최문수,김창영,장창준,최영,엄기영 국제문화기술진흥원 2019 The Journal of the Convergence on Culture Technolo Vol.5 No.4

Exchanging sheets for patients is one of the worst and one of the factors that makes the nursing environment difficult. Many beds with various functions for the patient have already been developed, but there is no device for automatically changing the sheets. In this study, we developed and tested the first automatic sheet changer for a medical bed and verified its performance. The developed automatic seat changer uses a torque limiter to properly adjust tension and exchange a dirty sheet and a new seat at the same time. The designed automatic sheet changer was experimentally confirmed to be properly operated and installed in a integrated multi-functional bed with bed sores prevention and automatic patient transfer functions. 환자를 위해 시트를 교환하는 일은 궂은일에 속하며 간호환경을 힘들게 하는 요인 중에 하나이다. 환자를 위한 다양한 기능들을 갖는 많은 침대들이 이미 개발되어 있으나 시트를 자동으로 교환하는 장치는 아직 없다. 본 연구에서는 의료용 침대를 위한 시트 자동 교환 장치를 최초로 개발하고 시험하여 성능을 검증하였다. 개발된 시트 자동 교환 장치는 토크 리미터를 사용하여 장력을 적절히 조절하며 오염된 시트와 새로운 시트를 동시에 교환한다. 설계된 시트 자동 교환 장치는 기 개발된 욕창 예방, 환자 자동 이송 기능을 갖는 다기능 통합 침대에 장착되어 적절히 동작하는 것을 실험을 통해 확인하였다.

Kang, Suk-Hwan,Kang, Yong,Han, Kun-Hee,Jin, Gyoung-Tae 한국공업화학회 2004 Journal of Industrial and Engineering Chemistry Vol.10 No.3

Effects of pressure on the bubble properties, such as pierced length, rising velocity, and frequency, and on the minimum fluidization velocity were determined in gas-solid fluidized beds by means of a cross- correlation function and a power spectrum of pressure fluctuations. The pressure fluctuations along the axial distance above the distributor were measured by a differential pressure transducer in the pressurized gas-solid fluidized bed [0.1 m (I.D.) 2.0 m (high)] Sand and silica sand, having mean diameters of 0.59 and 0.18 mm, respectively, and each having an apparent density of 2590 ㎏/㎥, were used as bed materials. The pierced length and rising velocity of the bubbles decreased, but the bubble frequency increased, upon an increase in the system pressure. The minimum fluidization velocity of the particles decreased considerably upon increasing the system pressure. The bubble flow behavior in the bed became more periodic and predictable as the bed pressure increased.
