This study, to confirm the mediating effect of knee pain on cognitive functions and depression in older adults, and as an interdisciplinary research between the physical and psychological mechanisms, confirmed the identifying group differences by gender, age, and educational attainment of older adults, and aimed to research the improvement of cognitive functions, which is a main factor of dementia's risk prediction. The analysis data was from the 8th Korean Longitudinal Study of Ageing (KLoSA) in 2020, and the research model was verified using Process macro and model #4. The main analysis results are as follows. First, depression partially mediation effect of knee pain on cognitive functions. Second, the mediation effect of depression by gender was significant, but the direct effect in the male older adults group was twice that in the female older adults; the indirect effect did not vary significantly based on gender. Third, the mediating effect of depression by age was relatively greater in the old-old aged group than in the young-old aged one. Fourth, as for the mediating effect of depression according to the classification of educational attainment, the mediating effect was not significant in the group with a college degree or higher education but was significant in the remaining three sub-groups. Based on the results, this study makes implications for the need for active intervention strategies to improve cognitive functions, focusing on group differences by gender, age, and educational attainment in the management of knee pain and depression.

The flexors and extensors of the knee joint are essential for maintaining body stability. The purpose of this study was to investigate the correlation between the isokinetic parameters of the knee flexor and extensor muscles and the function of the lower extremity muscles. Twenty-two healthy adults participated in this study. The time to peak torque (TTP), acceleration time (AT), and peak torque (PT) of the knee flexor and extensor muscles were measured. A 20m sprint, Sargent jump, one leg hop test, and side shuffle were measured to evaluate lower extremity function. The correlation between each variable was analyzed using Pearson correlation coefficient. PT of the knee flexor showed a significant correlation with single leg hops and 6M hops in a single leg. PT of knee extensors was found to be significantly correlated with Sargent jumps and triple hops. Based on the results of this study, we suggest that the strength of the knee flexor and extensor muscles has the potential to be used to predict lower extremity function.

본 연구는 동작분석장치를 이용하여 하지동작분석을 시도함으로서 실제 동작 시 적응 할 수 있는 의복설계를 위한 기초 자료로서 하지부 실루엣 변화의 특성을 밝히고자 하였다. 대퇴돌기점을 기준으로 본 하지동작의 진행방향 이동과 상향 방향이동을 살펴보았는데 보행유형에 따라 여유량이 특히 요구되는 부위가 각기 다르며, 부위별 필요 여유 량도 각기 다르다는 것을 알 수 있었으며 , 이러한 보행유형 별 스커트 실루엣의 특징은 기능복 설계 시 고려되어야 하겠다. 평지보행 시는 발목부위가 전면방향보다 후면방향으로 이동의 범위가 크므로 트임이나 주름이 뒷면에 있는 것이 적합하고, 계단승강이나 버스승강의 경우 무릎전면에 여유량이 필요하므로 주름이나 트임을 앞쪽에 주는 것이 바람직하며 그 길이는 대퇴돌기점 높이정도에서 시작하여야 하고 무릎아래에 있는 앞트임은 하지동작에 도움이 되지 않음을 알 수 있었다.

DICOM images of patellofemoral bones were converted into a stereolithography file, and a Unigraphics CAD program was used to create a CAD modeling in which there exists point, line and facet information. The modeling extraction of joint facets was performed by linking two adjacent points into lines in the stereolithography file by using the Unigraphics rapid spacing function and then linking the lines into facets to complete the entire modeling. This modeling extraction was performed based on the anatomical knowledge of joint facet directions. As a result, a personalized space modeling and solid modeling were produced for the joint facets of patellofemoral bones. This was followed by a CAM control computing operation of solid modeling on graphite materials and 5-axis machining of patellofemoral bones. That is the description of a method for a personalized implant modeling by using DICOM images of patellofemoral bones.
