As smart devices have proliferated and mobile networks have accelerated, various wired IT(Information Technology) services are transplanted in wireless environments. Cloud computing service, enabling individual users or firm users to download data from a server and upload data after manipulating data, is also available in mobile devices. Unlike cloud service in wired network environments, mobile cloud service provides differentiated aspects in mobility, security issues caused by persistent connection to networks. In this paper we aim to analyze the factors affecting the user attitude and their structural relationships towards mobile cloud service use. We extend TAM(Technology Acceptance Model) to consider the characteristics of mobile environments. Research findings, analyzed by SEM(Structural Equation Model), are explained and practical implications are presented with concluding remarks.

The digital colour reproduced on a display can be transferred to the image through various colour spaces, and the colour transferred to the image is one of the most important factors, among both subjective and objective factors, in image quality evaluation. Therefore, the digital colour must be continuously studied objectively and quantitatively along with the display development. At the same time, the subjective evaluation should be accompanied by systematic and quantitative research as the visual characteristics must be fully reflected. In this study, we applied different lightness levels of the background in order to examine the movement phenomenon of colour properties among the digital colour properties reproduced on the display. A psychophysical experiment was conducted for the condition where various colours were presented in the background, and the size of the colour stimulus was divided into the foveal vision and peripheral vision. Based on the evaluation results of the experiment, the colour properties movement phenomenon is identified according to the lightness of the background and the size of the colour stimulus for five colours among KS basic colours selected by experimental stimulus. Furthermore, a research direction to reproduce colour on displays in the future is proposed.

Lately, the three mobile telecom companies in Korea are competing for the launch of Internet of Things services for using home. Typical launched services are in the smart home related fields. However, Internet of Things as mobile telecom based are at an early stage, expected that various services will be started continuously. At this point, we have been planning to analyze the preference of Internet of Things for objects based on the services already launched. In order to apply the analytic hierarchy method, the first stage factors were designed as Safety, Security, Health care, Intelligence and Home appliances. In addition, the second stage factors were organized into 18 detailed services presented in the conceptual model. As a result, Health care (23.2%) was the most preferred priority. These results can be interpreted as the result of interest in health by improving income. We presented the theoretical and practical implications of these results.

This study was to investigate basic level of physical activity test that reflects activity of daily living(ADL) for institutionalized elderly women. The subjects were 105 elderly women over than 65 years living in long-term care facilities located in Daejeon and Chungnam. The measured eight items related to ADL were tested and the data was analyzed by descriptive statistics, one-way ANOVA, factors analysis and correlation. The results were statistically significant differences. Among eight test items, two factors(muscle strength and mobility) were extracted by principal component factor analysis(PCA). The two factors are appropriate domains for assessment of basic physical activity of institutionalized elderly women. By using Pearson's correlation, between two factors and age, the first principal component scores were significantly decreased with age increasing. Degradation of ADL must be prevented for institutionalized elderly women through maintain muscle strength and mobility.

The purpose of this study was 1) to investigate professional sports fans' perception of immigrants and changes of athletes' nationalities, and 2) to examine how the fans' perception affected the perception of changes of athletes' nationalities. Results indicated that first the fan showed a neutral attitude toward the immigrants. In the results of the regression analysis containing foreign athletes naturalized as Korean citizens as the dependent variable, independent variables (i.e., gender and acceptance) explained 39.1% and 38% of the dependent variable, respectively, within [naturalization positive]. Within [naturalization negative] female fan and exclusive perception of immigrants positively predicted the objection to changes of athletes' nationalities. Lastly, in the results of the regression analysis containing Korean athletes who naturalized as foreign citizens as the dependent variable, fans who were older and rated higher on exclusive perception of immigrants had more negative perception of the dependent variable. Female fans perceived changes of athletes nationalities as personal choice.
