Pressure sores are an unresolved human challenge. In this study, a keyboard-type medical bed was developed and a body pressure sensor was installed to provide a method to control the keyboard so that the pressure sores do not reach the critical pressure. For this, a keyboard-type mattress using a 4bar link is developed, and a method of controlling the height adjustment of the keyboard within the critical pressure through a body pressure sensor is used. There is a feeling of discomfort in the body when the keyboard is raised and lowered from pressure sores, which is an important factor: pressure x time, and only time control is performed, but if the proposed method is used, pressure is controlled within the critical pressure, thereby preventing bedsores in a comfortable state. The effectiveness and validity of the developed medical bed system were verified through theories and experiments.

Recently, various motion beds have been actively developed and popularized. The motion bed has the functions of height adjustment, back plate rising, knee lifting, tilt function and left / right rotation, and the remote control can conveniently be used by the patient himself or the caregiver to move the patient. However, since the medical bed for use does not have a function of preventing pressure ulcers, exchanging sheets, and transferring patients, it is necessary to disperse body pressure by using a pressure ulcer prevention matrix to prevent pressure ulcers. However, it is accompanied by muscle strength and hard work, and nurses are avoiding difficult nursing care. In this study, we developed the first prototype in the world and confirmed that the system works normally with the goal of developing multifunctional beds that automatically perform the prevention of bed sores, the exchange of sheets and the transfer of patients in order to facilitate such nursing work. It is anticipated that the proposed multifunctional motorized bed in the future will be a model of a medical robot for smart healthcare.

To measure the full scale fire test and heat release rate of bed mattresses according to the building compartment space, a fire test was performed using the Standard test method to determine the heat release rate of mattresses and mattress sets (KS F ISO 12949: 2011). Both test locations showed similar fire growth until approximately 3 minutes after burner ignition. After 3 minutes, the heat release rate in the test room was higher than the open calorimeter. For bed mattresses (SS), the maximum heat release rate in the open calorimeter was 735 kW and the maximum heat release rate in the test room was 992 kW. For bed mattresses (Q), the heat release rate in the test room increased more rapidly than the open calorimeter. The maximum heat release rate in the open calorimeter was 1,087 kW (346 s) and the maximum heat release rate in the test room was 2,127 kW (287 s). The difference between the maximum heat release rate and the measurement time according to the test location was confirmed.

심한 화상환자를 치료하는 동안이나 피부이식을 하는 동안에 어떻게하면 환자를 따뜻하고 안전하게 보호할 수 있을까? 사용할 용액들, 홑이불, 수술대, 회복실 침대를 따뜻하게 준비해 놓고 에어컨을 끈다. 너풀거리는 꺼즈를 잘 다듬어 놓고 stockinette도 준비한다. 피부이식을 위하여 피부를 떼어낸 부위에도 화상부위와 마찬가지로 질산은 드레싱을 하며 피부에 식염수나 기름종류는 사용하지 말아야 한다.

아침 6시, 자동으로 기상음악이 흘러 나온다. 침대가 저절로 위로 치켜지면서 안마기가 등을 두드린다. 이와함께 침실의 커튼이 열리고 부엌에서는 자동전기밥솥이 식사를 준비한다. 욕실에서는 적당한 온도의 물이 욕조를 채우고 있다. 목욕을 마친 후 준비된 아침을 들고 문을 나서면 자동으로 문이 잠긴다. 차고의 승용차는 이미 원격조정으로 시동이 걸려 있다. 꿈 속의 이야기가 아니다. 컴퓨터 실험주택에서 실제로 현실화되고 있는 일이다. 컴퓨터에 의한 가정자동화(HA)의 모습이다.

With rapid growths of economy and technology, structures and forms of buildings have been diversified and complicated. Buildings also have become higher and larger than ever before. As a result, more people use a building and more combustibles exist in the building. Without understanding of combustion characteristics and the establishment of a fire safety plan in case of a residential fire, it is expected great loss of lives and properties. In this study, experiments were carried out to promote an understanding of the combustion characteristics of combustibles in the building. Sofa and bed were used as combustibles in the experiment. Heat release rate of the sofa was about 1.9MW. Heat release rate of the bed was approximately 650kW.
