Background: Because of the lack of accurate values for applied forces in manual therapy, manual therapists relies on the magnitude of the individual’s perception during applying the force. However, excessive loading maneuvers carry risks for patients.
Objective: To establish the relationship between the maximal force applied to swine skin with the specific region, sex, and baseline parameters of the subject.
Design: Ex-vivo Study and laboratory Experimental research
Methods: 3.5 kg of Korean pork sirloin that is a piece of swine was handled and it was set 3 dimensions; #A; #B; #C. Forty-seven participants who has no experience in physical therapy randomly carried out the experiment, indicated to push each place of the pressure spots with same posture and process under supervision from the instructor who has over 15 years of manual therapy, and we measured the pressure force in each time.
Results: The biggest pressure force was recorded in spot #A, and #B was represented after #C. Pressure on #A showed certain statistic relation with height (r=.317, p<.05) and weight (r=.434, p<.01); pressure on #B showed certain relation which has statistical meaning with only height (r=.401, p<.01); pressure on #C emerged to have statistic relationship with height (r=.308, p< .05)and weight (r=.428, p<.01). The age aspect revealed relation with pressure on #A, #B and #C, but that was not statistically significant.
Conclusions: It can be inferred that there is the most loss of pressure in the area where cartilage is like an island in the middle.
교량은 사회간접시설물의 핵심이 되는 도로의 주요 시설물이므로 공용기간 동안 안정성과 사용성이 확보될 수 있도록 건설되며, 교량의 안전성 확보를 위하여 현재 상태에서 건전성을 평가하는 것은 유지관리 업무에서 중요한 과제이다. 일반적으로 교량의 내하력 평가를 위해 차량재하시험을 통하여 횡분배윺을 측정함으로써 교량의 중첩거동 및 대칭거동을 확인할 수 있다. 그러나 공용중인 교량의 횡분배율을 측정하기 위하여 정적재하시험을 수행하고 있으며 교통통제의 어려움이 있다. 따라서 본 연구에서는 동적재하시험 및 상시진동시험에서 측정 된 교량의 변위응답 데이터를 경험적 모드분해기법을 이용하여 정적 성분의 변위를 추출하였다. 추출된 정적 성분의 변위를 이용하여 횡분배 율을 추정하였으며, 정적재하시험에서 측정된 횡분배율과 비교하였다.
