The wavelet transform was adopted as the transform for JPEG2000. However, wavelet has weakness about smoothness along the contours and limited directional information. So we use to other transform, called contourlet transform in compression. Objective quality assessment methods currently used Peak signal to noise Ratio(PSNR). But that is not very well matched to perceived visual quality. So new image quality assessment is required. In this paper, we propose a new method for image compression based on the contourlet transform, which has been recently introduced. In addition we evaluated compression image quality using PSNR and SSIM. Finally contourlet transform has a good result about images with smooth contours and SSIM is good method for image evaluation compared to PSNR.

The effect of additional amounts of subsidiary materials on texture of fish meat paste were examined using Instron Universal Testing Machine to obtain fundamental data for steamed Alaska pollack meat paste showing good quality. The hardness revealed the good correlation with jelly strength among the six kinds of parameters of Instron texturometer. Products with higher hardness showed a better quality, but those with hardness higher than 16kg showed decreasing quality with increasing hardness. Predicting the quality of steamed Alaska pollack meat paste with various additional amounts of subsidiary materials as a function of hardness, H, the equation could be deduced as follows: H=11.56+0.54Xcs, H=12.22-0.23Xsp and H=11.65-7.13Xpp. The reasonable equations for predicting the quality of steamed Alaska pollack meat paste with various additional amounts of mixed subsidiary materials could be summarized as follows: H=11.57+0.53Xcs+0.44Xsp, H=11.97-1.83Xpp-0.17Xcs, and H=11.58+0.08Xpp-0.23Xsp.

This study was conducted as a part of the project to evaluate the quality of mathematics instruction in the national curriculum system. The purpose of this study is to measure the consistency between teaching goals of mathematics curriculum, contents presentation of textbooks, and testing including adequacy of each element in mathematics instruction for 8th grade. To do this, we used MIQP (instructional quality profile for Mathematics) developed basing on the instructional quality profile (IQP) in the previous research of the project. First, the quality of textbooks' content presentation for 8th grade was found that the desirable levels in number and operation area and geometric area was relatively less compared to other areas, but it was generally good. Second, it was found that the quality of mathematics testing for 8th grade was good in terms of consistency with the curriculum's teaching goals, consistency with the content presentation of textbooks, and adequacy of testing. However, regional differences in the quality of testing showed that there were some deficiencies in regions outside the metropolitan.

With lower quality and three to four times higher price than those of imported malting barley, the competitiveness of domestic malting barley is decreasing. Although the causes can be found in that the domestic environments are much unfavorable to cultivate the malting barley compared with those of USA or Canada, it is mainly reasoned from poorer developments in variety of high quality malting barley as well as in cultivation technology. For assuring the competitiveness of domestic malting barley, therefore, not only the development of high quality malting barley suitable to the climatic environment of this country but also the political supports of the government are required. Also, in addition to the breeding of the good quality malting barley haying higher germinative energy, and heavier and larger kernels of good plumpness as well as lower protein content, the modification of quality inspection standards from the system relying only on the visual characteristics such as kernel size distribution rate, shrimped kernel rate, foreign materials and so on, to such system as those of developed countries haying quality criteria such as protein content for inspection is absolutely required for the quality improvement of domestic malting barley.

The development of an appropriate public service quality model has become increasingly recognised as an important subject of interest in the public sector as well as academia. In particular, the public systems enacted by governments are widely used and have a significant impact on national competitiveness. But few researches have been conducted to explore the quality dimensions of a public system service and empirically examine the relationship among related variables. Therefore, in this study, we strive to develop a quality measurement model of public system service that can be effectively used in practice. Using 601 samples gathered through a structured survey from project engineers, a conceptual quality model of public system is presented and discussed. Given the exploratory nature of this study, an exploratory factor analysis is used to investigate quality dimensions and partial least square (PLS) is employed in determining the structural relationships. From empirical results, we found that the quality dimensions of the public system had four distinct quality dimensions (design quality, environment quality, primary outcome quality, additive outcome quality). All four quality dimensions showed good representative factors in explaining user satisfaction. Perceived trust was proved to significantly mediate the relationship between quality dimensions and user satisfaction. Our research is expected to contribute to the literature by providing a good conceptual framework for assessing public system quality by linking four quality dimensions with user satisfaction. In particular, the developed model can elaborately measure process quality and multi-functional outcome quality of the system by the supplementation of design quality and additive outcome quality respectively. Practical implications are also suggested on the basis of our analysis.

High temperature superconductor shows a good electric and magnetic properties and is known as a good candidate in various electronic device application. At present the technique to construct multilayers composed of HTS films and insulator films has not been fully studied in domestic research institutes. Since the construction of any reasonable eletronic devices require the use of multilayers, the development of HTS eletronic devices has been limited. To manufacture multiplayer, several processing steps which involve deposition and ion millings are required. To manufacture a good quality multilayerd structure, not only the deposition techniques but also the proper patterning have to be developed. In this work, we have fabricated a YBCO/STO/YBCO multiplayer and studied the electronic properties of it.

Purpose: The purpose of this research was to examine the degree of care stress and the quality of life of grandmothers caring for their grandchildren while mother was employed. Method: A convenience sample of 107 grandmothers were measured for grandmother's care stress using a revised for of the PSI/SF and the quality of life tool by Andrew and Weinert. Descriptive statistics, t-test, and Pearson correlation coeffcients were used to analyze the data using SPSS/PC 10.0 Results: The results found that grandmothers' care stress was high according to their age and religion. Their quality of life was low according to their age, their present health status, income and sleep pattern. Their subjective care stress was a sense of social isolation, burden of caring for grandchildren, health problems, and conflict with adult children. Care stress and quality of life were found to be negatively correlated. This result was statistically significant. Conclusion: In conclusion, it was found that the care stress was high and affected quality of life. From this study it is proposed that there is a need to develop programs which consider grandmother' techniques in child care and health care to improve their quality of life. Ultimately, a good care environment for children will be good for the children's growth and development.
