The study on the Cell Survival for Bio Artificial Liver by using standardisation Extracorporeal Circulation Method
by Seonghwan Kim, Minwoo Cheon
Abstract: The only way to replace an already-impaired liver is a liver transplantation or artificial liver functioning as a liver. This research is on the standardization of perfusion to help increase the survival rate of hepatic insufficiency patients through the enhanced cell survival of artificial livers. Generally, artificial livers are used in the form of extracorporeal circulation with a mounted bioreactor. As artificial livers need to replace liver functions, to enhance the liver cell survival ratio in the bioreactor, the bioreactor performance needs to be improved. To this end, perfusion standardization is required in the extracorporeal circulation and each circulation pumps should be interoperable. In this recognition, this study looked at possible standardization of perfusion methods capable of increasing liver cell survival rate in order to find out the optimal standardized bio-reactor. As a result, perfusion 2 control was found to be essential in raising the cell survival ratio and perfusion 3 implementation enhanced the survival ratio.

A New Embedded Image Compression Scheme using Rate-Distortion Optimized Block Coding of Wavelet Coefficients
by Chang Mo Yang, Kwangsue Chung
Abstract: In this paper, we propose a new embedded image compression scheme which uses rate-distortion optimized block coding of wavelet coefficients. Unlike conventional embedded compression schemes which use the set partition or block partition coding methods according to the magnitude of wavelet coefficients, the proposed scheme achieves rate-distortion optimization by ordering wavelet coefficients or blocks according to their expected rate-distortion slopes. In addition, the proposed scheme uses a modified block partition method, and new context models for the entropy coding. Experimental results demonstrate that the proposed scheme not only produces embedded bit-streams, but also outperforms existing embedded compression schemes.
Keywords: Block Partition Coding; Embedded Image Compression; Rate-Distortion Optimization; RDBC; Wavelet.
Is smartphone creating a better life? Exploring the relationships of the smartphone practices,social capital and psychological well-being among college students
by Hua Pang
Abstract: Along with the development of wireless communication and the rapid diffusion of handset, mobile technologies have provided individuals with unprecedented new spaces for social interactions and multiple modes of expression, and as such, they are expected to enhance individuals social capital as well as psychological well-being. This empirical study investigates the relationship between the utilization of smartphones and social capitals formation and maintenance with an emphasis on youth uses and practices. In addition to assessing bonding and bridging social capital, it also explores maintained social capital by evaluating how mobile communication influences ones individual capability to keep in touch with members of a formerly inhabited community. The results from a survey of college students (N = 346) demonstrate a strong linkage between smartphone use and three different modes of social capital. And the strongest relationship, revealed by Pearson correlation coefficient analysis, is between smartphone use and bridging social capital. However, the present study did not find evidence that the intensity of smartphone usage predicts two measures of psychological well-being including self-esteem and life satisfaction. Limitations and suggestions for future research are discussed.
