세계보건기구(WHO)의 자료에 따르면, 흡연자의 절반 가까이가 담배에 의해 생명을 잃는다고 한다. 담배는 매년 600만 명의 생명을 앗아간다. 그 중 500만명 이상은 현재 흡연 중이거나 끊은 사람들이다. 60만 명 이상의 비흡연자들도 간접흡연에 의해 생명을 잃는다. 긴급한 조치를 취하지 않는다면 매년 사망자는 계속 증가하여 2030년엔 800만 명을 넘을 것으로 예상된다.

This study analyzed research trends of assistive devices used to prevent and support disability and increase convenience for people with disabilities in their daily lives. As a result, related research has continuously increased, and the research area has expanded from survey research to service-related research and assistive device development research. In addition, with regard to the use of related terms, terms such as 'rehabilitation engineering' and 'rehabilitation assistive technology' were used in the early stages. Currently, terms such as 'assistive technology', 'assistive technology service', 'assistive technology device', and 'assistive device' have been mainly used.

This paper is case study on design, manufacture and application of customized assistive device for the ADL of person with brain lesions. The study had carried out from October 2010 to November 2010 and 2 clients from Assistive device case management demonstration project which is performed by Daegu assistive and rehabilitation center had participated. Case A, a 47-year-old man with brain lesions, stays only on the floor and could not get close to the usual toilet by himself because of the poor low extremities muscle strength and function. The moveable-toilet and customized ramp had applied to Case A. He clambers up the ramp and reach to the toilet easily. Case B, a 8-year-old boy with brain lesions, had difficulties with self-feeding because of his clumsy hand. Several existing feeding aids were applied but not appropriated. A customized feeding aid was designed and manufactured out of regard of Case A's ROM and right hand size. And his occupational therapist works together continuously to make him feed himself in the near future. Already-made assistive devices were not appropriate to Case A and B and to solve this problem, customized assistive devices were applied. The importance and needs of design and manufacture of assistive device were recognized through these case study.

Inversion therapy has been used to relieve backpain, decrease pressure on the discs between vertebrae and stretch musdes as early as 400 BC. Gravity Guidance Inversion Table was introduced in 1960's and has been commercialized mostly for relieving backpain. in United States. But this machine needs to adjusted and possible sudden movement can cause severe injury to the users. In the 1990's, motor assisted inversion cram was introduced in Germany. But this inversion cram is too heavy and inconvenient to be used at home. In these days, the inversion machine become popular equipment in fitness clubs and health care places for relieving backpain as well as stretching muscles. And there is a growing need for home use version of motorized inversion machine. In this study, the motorized inversion machine was developed to be used for stretching exercise at home. The design became compact, simple and foldable as the results of adapting the wabble mechanism. And the machines are optimally designed by analyzing the torques applied to the machine by diverse physical size of users.

This case research investigates on how hearing aids, which is one of disability aids, is becoming a smart device, focusing on the case of Starkey Hearing Technologies(Starkey Inc.). Starkey, founded in 1967, has been a leader in innovating forms and functions of hearing aids, and has recently introduced the world's first hearing aid implemented with AI and biological sensors. In this study, history of disability aids, hearing aids(especially Starkey Inc.'s), smart wearable devices and smart earphones are compared. It has been found that recently, there has been a breakdown of boundaries between hearing aids and smart wearable devices in terms of their functions, since entertainment and life assistant functions are added to hearing aids. Based on this trend, the development model of disability aids and smart wearable devices are derived, and according social changes are discussed.

Important crime prevention is emphasized. Depending on the type of criminal act itself, but with many material and human damage because it is a threat to the safety of civil life. The traditional police power of the police in patrolling the derailment by the diversification of the crime, globalization, organizing, specialization, and ferocious anger by far exceeds the capabilities of the police crime prevention are occurring. Civilian police crime prevention organizations in the area of the region as a base for complementary activities, and even if the purpose of commercial availability, but many organizations is the autonomous and spontaneous personality voluntary work civic life is to serve as the safety fence. But that suits the role of these organizations and social support and lack of institutional support and practical and effective crime prevention activities has not been effective. Law reform and the role of the Organization for the maintenance of redundancy, or a series of systematic effort to equip networks and take advantage of the functional and has been factory.

The spine is one of the most important skeletal joints, and it strongly affects the health of the musculoskeletal system. A normal spine has an S-shape, and it is very important to maintain this shape. Recently, spinal diseases such as low back pain have increased rapidly, especially among the elderly. Some of these diseases are caused by congenital spinal disorders and sporting and accident injuries as well as by bad postures. Improper spinal postures could generate excessive disc pressure, which is related to degeneration and pain. Therefore, in this study, we investigated the three-dimensional kinematic parameters of the thoraco-lumbar joint in several bad postures using a motion capture analysis technique. Different bad postures created a significant amount of flexion/extension, side bending, and axial rotation angle compared with neutral postures. Further study is necessary to investigate the disc pressure and ligament force due to the increase in joint rotation from the bad postures.
