Towards Building Health Systems Lawrence Elaine; Felix Navarro Karla; Sax Christian Leszek Koszalka, Daniela Dragomirescu This paper reports on a series of interviews with three mainstream and three alternative/complimentary health professionals about the use of interactive technologies as a tool to improve the physical and mental well-being of the elderly. The questions are based around an Analytic Framework for investigating Interactive Technologies and the elderly. Four balance games using the Wii were demonstrated to the interviewees and their opinion of the suitability or otherwise of these games are discussed. The chosen games did not meet with universal approval but did provide us with useful insights on how to ensure the development of appropriate games for the elderly.

Benefits of Intercultural Cooperation in Sport-for-Development: Complementing International Expertise with Local Community Knowledge Schulenkorf Nico Lidor, R; Schneider, K-H; Koenen, K There is increasing evidence that government agencies and NGOs are turning to sport-for-development (S4D) projects as a tool for inclusive social change, reconciliation and peace-building in divided societies. In a developing world context, it is particularly challenging for (Western) sport organisers and â¿¿change agentsâ¿¿ to establish and maintain projects that are both professionally managed and culturally meaningful. Surprisingly, the involvement of international change agents and their cooperation with local communities at intergroup development projects has not received much empirical investigation. In addressing this gap, the purpose of this paper is twofold: First, an analysis of the roles and responsibilities of a sport event change agent in the ethnically divided Sri Lanka is presented. Central to this analysis are the sport and event activities of the Asian-German Sports Exchange Programme, and their contribution to reconciliation and peace building in Sri Lanka. Second, in discussing the research findings and their importance for inclusive and sustainable development, this paper incorporates additional practical experiences from S4D projects such as the â¿¿Football for Peaceâ¿¿ initiative in Israel, and the â¿¿Healthy Communitiesâ¿¿ program in Vanuatu. Despite their contextual differences, all these sport-based development projects are designed to make a lasting difference within and between disadvantaged communities.

Clustering Nuclei Using Machine Learning Techniques Peng Yu; Park Mira; Xu Min; Luo Suhuai; Jin Jesse Sheng; Cui Yue; Felix W; Santos Leonardo D Yan Li â¿¢ Jiajia Yang â¿¢ Peng Wen â¿¢ Jinglong Wu Cervical cancer is the second most common cancer among women. Meanwhile, cervical cancer could be largely preventable and curable with regular Pap tests. Nuclei changes in the cervix could be found by this test. Accurate nuclei detection is extremely critical as it is the previous step of analysing nuclei changes and diagnosis afterwards. Recently, computer-aided nuclei segmentation has increased dramatically. Athough such algorithms could be utilised in the situation for spare nuclei since they are intuitively detected, the segmentation for the complicated nuclei clusters is still challenging task. This paper presents a new methodology for the detection of cervical nuclei clusters. We first detect all the nuclei from the cervical microscopic image by an ellipse fitting algorithm. Second, we chose some high-relevant features from all the the features we obtained in last step via F-score, which is based on to what extent one feature attributes to results. All the ellipses are then classified into single ones and cluster ones by C4.5 decision tree with selected features. We evaluated the performance of this method by the classification accuracy, sensitivity, and cluster predictive value. With the 9 selected features fromt he original 13 features, we came by the promising classification accuracy (97,8%).

Fast tracking of a given heart rate profile in treadmill exercise Weng Kaili; Turk Basil; Dolores Louis; Nguyen Tuan; Celler Branko; Su Steven; Nguyen Hung Ricardo Armentano This paper investigates the application of a multi-loop PID controller in an automated treadmill exercise machine. The approach is to design a computer-controlled treadmill control system for the regulation of heart rate (HR) during treadmill exercise. A single-input and multiple-output (SIMO) controller was implemented to fast track a given heart rate profile in treadmill exercise. Two separate single-input and single-output (SISO) PID control systems are initially implemented to modify either the treadmill speed or its angle of inclination in order to achieve a desired HR. The purpose of this paper is to apply a SIMO control system by implementing a control algorithm which includes the two PID controllers working simultaneously to track the desired HR profile. The performance of the SIMO and SISO control systems are compared through the closed loop responses recorded during experimentation. This would also help future development of safe treadmill exercise system.
