Teaching ‘community engagement’ in engineering education for international development: Integration of an interdisciplinary social work curriculum     

Dorie J. Gilbert  Mary Lehman Held  Janet L. Ellzey  William T. Bailey  Laurie B. Young 《European Journal of Engineering Education》2015,40(3):256-266

This article reviews the literature on challenges faced by engineering faculty in educating their students on community-engaged, sustainable technical solutions in developing countries. We review a number of approaches to increasing teaching modules on social and community components of international development education, from adding capstone courses and educational track seminars to integrating content from other disciplines, particularly the social sciences. After summarising recent pedagogical strategies to increase content on community-focused development, we present a case study of how one engineering programme incorporates social work students and faculty to infuse strategies for community engagement in designing and implementing student-led global engineering development projects. We outline how this interdisciplinary pedagogical approach teaches students from the two disciplines to work together in addressing power balances, economic and social issues and overall sustainability of international development projects.  相似文献

Spectral clustering with physical intuition on spring–mass dynamics     

Jinho Park  Moongu Jeon  Witold Pedrycz 《Journal of The Franklin Institute》2014

In this paper, we provide a new insight into clustering with a spring–mass dynamics, and propose a resulting hierarchical clustering algorithm. To realize the spectral graph partitioning as clustering, we model a weighted graph of a data set as a mass–spring dynamical system, where we regard a cluster as an oscillating single entity of a data set with similar properties. And then, we describe how oscillation modes are related with eigenvectors of a graph Laplacian matrix of the data set. In each step of the clustering, we select a group of clusters, which has the biggest number of constituent clusters. This group is divided into sub-clusters by examining an eigenvector minimizing a cost function, which is formed in such a way that subdivided clusters will be balanced with large size. To find k clusters out of non-spherical or complex data, we first transform the data into spherical clusters located on the unit sphere positioned in the (k−1)-dimensional space. In the sequel, we use the previous procedure to these transformed data. The computational experiments demonstrate that the proposed method works quite well on a variety of data sets, although its performance degrades with the degree of overlapping of data sets.  相似文献   

Synchronization of discrete-time complex dynamical networks with interval time-varying delays via non-fragile controller with randomly occurring perturbation     

M.J. Park  O.M. Kwon  Ju H. Park  S.M. Lee  E.J. Cha 《Journal of The Franklin Institute》2014

This paper addresses synchronization problem for discrete-time complex dynamical networks with interval time-varying delays. In order to achieve the synchronization, a feedback controller subjected to randomly occurring perturbations will be considered. The randomly occurring perturbations are assumed to belong to the Binomial sequence. By constructing a suitable Lyapunov–Krasovskii functional, and utilizing reciprocally convex approach and Finsler?s lemma, the synchronization criteria for the networks are established in terms of linear matrix inequalities (LMIs) which can be easily solved by various effective optimization algorithms. The networks are represented by the use of Kronecker product technique. The effectiveness of the proposed methods will be verified via numerical examples.  相似文献   

Programmed sample delivery on a pressurized paper     

Joong Ho Shin  Juhwan Park  Seung Hoon Kim  Je-Kyun Park 《Biomicrofluidics》2014,8(5)

This paper reports a method to control the fluid flow in paper-based microfluidic devices simply by pressing over the channel surface of paper, thereby decreasing the pore size and permeability of a non-woven polypropylene sheet. As a result, fluid resistance is increased in the pressed region and causes flow rate to decrease. We characterize the decrease of flow rate with respect to different amounts of pressure applied, and up to 740% decrease in flow velocity was achieved. In addition, we demonstrate flow rate control in a Y-shaped merging paper and sequential delivery of multiple color dyes in a three-branched paper. Furthermore, sequential delivery of multiple fluid samples is performed to demonstrate its application in multi-step colorimetric immunoassay, which shows a 4.3-fold signal increase via enhancement step.  相似文献   

Study for optical manipulation of a surfactant-covered droplet using lattice Boltzmann method     

Se Bin Choi  Sasidhar Kondaraju  Joon Sang Lee 《Biomicrofluidics》2014,8(2)

In this study, we simulated deformation and surfactant distribution on the interface of a surfactant-covered droplet using optical tweezers as an external source. Two optical forces attracted a single droplet from the center to both sides. This resulted in an elliptical shape deformation. The droplet deformation was characterized as the change of the magnitudes of surface tension and optical force. In this process, a non-linear relationship among deformation, surface tension, and optical forces was observed. The change in the local surfactant concentration resulting from the application of optical forces was also analyzed and compared with the concentration of surfactants subjected to an extensional flow. Under the optical force influence, the surfactant molecules were concentrated at the droplet equator, which is totally opposite to the surfactants behavior under extensional flow, where the molecules were concentrated at the poles. Lastly, the quasi-equilibrium surfactant distribution was obtained by combining the effects of the optical forces with the extensional flow. All simulations were executed by the lattice Boltzmann method which is a powerful tool for solving micro-scale problems.  相似文献

The Evolution and Cultural Characteristics of Korean Professional Soccer     

Kyoungho Park 《国际体育史杂志》2017,34(17-18):1964-1980

Abstract

Since it was introduced in the late nineteenth century, soccer has been one of the cultural driving forces for Koreans in overcoming national hardships during the dark ages marked by imperial occupations, war, and division during the modern era. This study was carried out to investigate the cultural backgrounds and characteristics due to which soccer has entered an era of professionalization under the name of the Super League. Korean professional soccer started in 1983 under the name of the Super League, not by popular demand but by from political backgrounds. The sport was off to a bad start, and this became an inherent limitation and the reason Korean professional soccer did not flourish. In addition, although Korean professional soccer had grown rapidly in terms of quantity based on a consistent increase in professional teams and the introduction of advanced systems, the cultural limitations of an incomplete local franchise system and a lack of public attention were revealed. Korean professional soccer has shown a variety of sociocultural limits while rapidly developing in its short history. Nevertheless, having a short history indicates the system is young, which means it has the opportunity to mature. Korean professional soccer has sufficient potential and it can be directed toward a brighter future.  相似文献
