A properly prescribed wheelchair may be able to normalize tone. decrease pathologic reflex activity, improve postural symmetry, enhance range of movement, maintain and/or improve skin conduit)n. increase comfort and sitting tolerance, decrease fatigue, and improve function of the autonomic nervous system. Whereas a poorly prescribed one can actually exacerbate the problems associated with a disability. Maintained for longer without relief, pressure concentrations may also lead to tissue breakdown. Pressure sores continue to be a major problem for many disabled individuals. Many groups of disabled individuals have a very high incidence of pressure sores, including those individuals with spinal cord injuries. hemiplegia, multiple sclerosis. cancer. and the disabled geriatric population. It is important to understand the factors which predispose an individuals to the development of a pressure sores. Those factors can divided into extrinsic factors, related to the individual's immediate environment and intrinsic factors. related to their medical or physical condition. Pressure sores are generally preventable through sensible pressure management based on an understanding of the causes of pressure sores, risk factors and methods of redistributing pressure.

Purpose: This study sought to identify the utilization and confidence in assistive technology (AT) for pediatric physical therapists (PPTs) and pediatric occupational therapists (POTs) for the purpose of improving the utilization of AT in clinics. Methods: The subjects of this study were 167 therapists (98 PPTs and 69 POTs) who work at general hospitals, welfare centers, facilities for the disabled, and special education schools in Seoul and Gyeonggi province. The frequency analysis and chi-squared test were used. Results: This study found that both PPTs and POTs recognize that AT benefits infants with disabilities; however, they show low confidence in using AT. Applications of AT are concentrated on wheelchairs for mobility and assistance with seating position, with orthotics/prosthetics for both purposes. POTs were found to use a wider variety of AT devices. While both PPTs and POTs frequently select/recommend devices, both groups are less involved with delivery methods, manufacture of devices, and education on AT use. Conclusion: These findings show the actual conditions of utilization and confidence in AT of PPTs and POTs deeply involved with AT, and emphasize that AT training is essential for pediatric treatment by comparing domestic and foreign studies.

This paper statistically reviewed for the USNCAP frontal crash test results carried out by NHTSA. Vehicle samples were selected on total 20 vehicles which were included on 15 vehicles for MPV&SUV and 5 Pickup. The results was summarized as followings. The performance for the driver was better than the passenger's in the average sense. There exist distinctions between the driver and the passenger on the USNCAP front test procedure, for example dummy size, seating position and airbag style. Therefore these differences originated in the statistical results. Main effect was Neck injury for crash performance on both dummies on the average value. Root cause of neck injury was different for each dummy, ie, the driver caused from Nte & Ntf, but the passenger did absolutely Nte mode. Reliability evaluated from the standard deviation was highly dependent upon chest injury on the driver and neck injury on the passenger. Restraint system was also summarized.

This study analyzed the comparative importance of the selection of a restaurant for solo diners, and suggests a solution for the ideal type of the restaurant that are appealing to solo diners using conjoint analysis techniques. A total of 280 questionnaires were distributed to consumers who had experience dining alone from June $7^{th}$, 2017 to June $14^{th}$, 2017, and 261 were completed (93.21%). As a result, the importance of the attributes of the restaurant was found to be the menu for solo diners (36.92%), price (30.29%), seating for solo diners (20.87%), and serving time of food (11.91%). The ideal combination of selection attributes was found to be having a menu for a solo diner, having a seat for a solo diner, meal service time of less than 10 minutes, and a low price of 2,500won. These results will form a database that contributes to the development of differentiated products and is building marketing strategies that can satisfy the needs of solo diners.

본 증례에서는 소수 잔존치를 가진 환자에 있어 새로운 인상 채득법을 이용해 국소의치를 제작하였다. 이 방법에서는 McLean의 기능인상법의 개념에 따라 임시 의치를 이용한 기능 인상채득 후에 비가역성 하이드로콜로이드로 overimpression을 채득하였다. 이러한 방법은 모델링 컴파운드를 사용한 변연 형성의 필요성이 없으며, 짧은 시간에 과연장되지 않은 의치 인상을 채득할 수 있으며 개인 트레이가 정확하게 적합된다는 유용성이 있다.

연구의 목적은 트랙터와 운전자의 인터페이스에서 중요한 연결고리인 트랙터 시트에 대한 인간공학적 설계인자의 도출이다. 대상 인구집단은 한국과 미국의 성인남녀이며 앉은엉덩이오금수평길이, 앉은어깨뼈높이, 앉은팔꿈치 높이 등 7종의 인체측정변수를 사용했다. 시트 설계 인자로는 좌석면의 크기, 등받이의 크기 및 팔걸이의 위치를 도출했다. 척주의 형태와 피복 효과 또한 고려되어야 하며, 본 연구의 결과가 소형 트랙터에 적용되는 시트의 설계 과정에서 가이드라인으로 활용되기를 기대한다.

최근 현대인들은 많은 업무와 학업으로 인한 좌식 생활의 빈도가 증가하면서 잘못된 자세와 잘못된 습관으로 인해 습관성 척추-골반 질병이 많이 발생하고 있다. 따라서 이를 방지하고 지속적인 바른 자세를 유도하기 위해서는 착석 정보를 기반으로 자세정보를 판단하여 유도할 수 있는 시스템이 요구된다. 본 논문에서는 자세안정도를 평가하기 위하여 추적 계측할 수 있는 장비의 개발과 잘못된 자세가 검출될 시에는 사용자에게 알려주어 실시간 모니터링을 통해 스스로 자세를 교정하는데 도움을 주는 어플리케이션의 구현에 대해 기술하였다.

The resonance behaviour needs be understood to identify the mechanisms responsible for the dynamic characteristics of human body, to allow for the non-linearity when predicting the influence of seating dynamics, and to predict the adverse effects caused by various magnitudes of vibration. However, there are currently no known studies on the effect of vibration magnitude on the transmissibility to thoracic or lumbar spine of the seated person, despite low back pain(LBP) being the most common ailment associated with whole-body vibration. The objective of this paper is to develop a proper mathematical human model for LBP and musculoskeletal injury of the crew in a maritime vehicle. In this study, 7 degree-of-freedom including 2 non-rigid mass representing wobbling visceral and intestine mass, is proposed. Also, when compared with previously published experimental results, the model response was found to be well-matching. When exposed to various of vertical vibration, the human model shows appreciable non-linearity in its biodynamic responses. The relationships of resonance for LBP and musculoskeletal injury during whole-body vibration are also explained.

This dissertation tried to analyze passenger behaviors after an accident with the possibilities of a variety of accidents open reflecting the phases of the times of increasing interests in safety of passengers as the use of means of transportation such as cars and airplanes is increasing. Because a lot of data on head-on collisions, broadside collisions and reverse side collisions have been gathered through lots of experiments and interpretations, I chose to study a relatively unfamiliar subject, dropping collision. For example, I tried to study passenger behaviors in seating position after a dropping collision in preparation for falling accidents due to recent frequently-occurring sinkholes, driver's carelessness or mechanical problems. I used MADYMO, passenger behavior interpretation program, and experimented with 2 meters high Drop Test device which I made in person to increase the reliability of the results. On the basis of these, I compared the real experiments with interpretations.
