Prospects For An Fta Between Australia And Korea, Charles Harvie

Faculty of Commerce - Papers (Archive)

Since the I 960s, trade opportunities based on complementary economies have driven the Australia-Korea economic relationship. Australia exported raw materials, principally minerals and energy, which Korea processed and subsequently sold on domestic and international markets. In return Australia purchased increasing volumes of Korean manufactures, initially textiles, clothing and footwear and later automobiles. With the onset ofthe financial and economic crisis in Korea during 1997-98 trade and investment opportunities were severely constrained. However, in the wake of the crisis, and the rapid recovery of the Korean economy underpinned by corporate and financial sector reforms, trade and investment opportunities in traditional areas …

The Relationship Between Education And Food Consumption In The 1995 Australian National Nutrition Survey, Anthony Worsley, Roswitha Blasche, Kylie Ball, David Crawford

Faculty of Social Sciences - Papers (Archive)

Objective: To assess the relationship between education and the intake of a variety of individual foods, as well as groups of foods, for Australian men and women in different age groups.

Design: Cross-sectional national survey of free-living men and women.

Subjects: A sample of 2501 men and 2739 women aged 18 years and over who completed the National Nutrition Survey (NNS) 1995.

Methods: Information about the frequency of consumption of 88 food items was obtained using a food-frequency questionnaire in a nation-wide nutrition survey. Irregular and regular consumers of foods were identified according to whether they consumed individual foods less …

Finite-Element Analysis To Determine Effect Of Monolimb Flexibility On Structural Strength And Interaction Between Residual Limb And Prosthetic Socket, Winson Lee, Ming Zhang, David A. Boone, Bill Contoyannis

Faculty of Engineering and Information Sciences - Papers: Part A

Monolimb refers to a kind of transtibial prostheses having the socket and shank molded into one piece of thermoplastic material. One of its characteristics is that the shank is made of a material that can deform during walking, which can simulate ankle joint motion to some extent. Changes in shank geometry can alter the stress distribution within the monolimb and at the residual limb-socket interface and, respectively, affect the deformability and structural integrity of the prosthesis and comfort perceived by amputees. This paper describes the development of a finite-element model for the study of the structural behavior of monolimbs with …

Finite Element Modeling Of Contact Interface Between Trans-Tibial Residual Limb And Prosthetic Socket, Winson Lee, Ming Zhang, Xiaohong Jia, Jason Cheung

Faculty of Engineering and Information Sciences - Papers: Part A

Finite element method has been identified as a useful tool to understand the load transfer mechanics between a residual limb and its prosthetic socket. This paper proposed a new practical approach in modeling the contact interface with consideration of the friction/slip conditions and pre-stresses applied on the limb within a rectified socket. The residual limb and socket were modeled as two separate structures and their interactions were simulated using automated contact methods. Some regions of the limb penetrated into the socket because of socket modification. In the first step of the simulation, the penetrated limb surface was moved onto the …

Load Transfer Mechanics Between Trans-Tibial Prosthetic Socket And Residual Limb-Dynamic Effects, Xiaohong Jia, Ming Zhang, Winson Lee

Faculty of Engineering and Information Sciences - Papers: Part A

The effects of inertial loads on the interface stresses between trans-tibial residual limb and prosthetic socket were investigated. The motion of the limb and prosthesis was monitored using a Vicon motion analysis system and the ground reaction force was measured by a force platform. Equivalent loads at the knee joint during walking were calculated in two cases with and without consideration of the material inertia. A 3D nonlinear finite element (FE) model based on the actual geometry of residual limb, internal bones and socket liner was developed to study the mechanical interaction between socket and residual limb during walking. To …
