This study examines determinants of film consumption. Using structural equation modelling, this study explores some factors that explained film consumption based on film tastes and information seeking and socio-demographic factors. The major results are as follows: firstly, the major factor for explaining film consumption was individual tastes for films. The higher the degree of tastes for films, the greater the degree of film consumption. Secondly, there were significant relationships between tastes for films and film related information seeking such as internet search behavior and the use of film blogs. More specifically, the use of film blogs partially explained the degree of film consumption. Thirdly, a demographic factor like gender was highly correlated to film consumption. However, an income factor was not correlated to fim consumption. In conclusion, the degree of film consumption was determined by tastes for flims, the use of film blogs and gender factors.

In the context of domestic consumption environment changes such as expansion of smartphones and increase of single-person households, hypermarket, which was the mainstream of the existing retail market, have recorded negative growth for the last three years due to declining sales. And it is not enough to analyze the influence relationship with other retail channels or investigate the cause of consumption movement. In this study, we analyzed the decline in the growth rate of hypermarket by demographic variables, consumption time, etc. And logistic regression analysis revealed the relationship between the decrease in consumption of hypermarket and the change in the proportion of sales of other retail channels. In addition, we surveyed consumers who have decreased consumption of hypermarket based on actual card consumption data to determine why they choose different retail channels. This is significant in that the result of quantitative analysis of changes in retail channel consumption and the result of qualitative reasoning converged to give a stereoscopic view of consumption.

In Korean society, digital contents such as VCC has introduced a new medium of advertisement and has become a culture. This research aims to investigate consumer characteristics for different types of consumption patterns for services dealing with digital contents. A total of 96 statements were extracted from literature review and popular press articles and 39 participants participated in this study. The results show 6 types of consumption patterns: Gak-jang-ee, Second-level Celebrity, Viewers, Politicians, Humanists, and Paris Hilton. These groups demonstrate consumer's behavioral characteristics and personal values. This study is meaningful in that it provides an insight for marketing strategies for corporations dealing with digital contents such as VCC.

The object of this study was to analyze the meaning of luxurious consumption, the subjects and the objects of luxurious consumption, the desires that propel luxurious consumption, and the luxurious consumption patterns of the past and the present. The materials and information used for this research were acquired by reviewing literatures from a library. The time frame used to separate the past and the present was the Second World War. The analyzed materials and contents for the research were the subjects and the objects of luxurious consumption, the desires that propel luxurious consumption, and the patterns of luxurious consumption. Comparing the trends of luxurious consumption of the past and present historically, the biggest differentiation between the past and present was the spread of subjects and objects of luxurious consumption. In the past, luxury consumption belonged to the wealthy only, but the accessibility of luxury consumption has increased to the point where anybody can buy what they want at will. Another difference was found in the desires that prompt luxury consumption and the consumption patterns of the past and present. Based on these results, several suggestions about luxury consumption were presented in this paper.

This study aimed to analyze preferences depending on consumption value in relation to fashion jewelry design, colors, and materials. For this, 156 female consumers participated in it as subjects, and for a research tool of consumption value, VALS (Values and Life Style) technique was employed to make an empirical analysis by dividing it into three types such as principle-oriented value, status-oriented value and behavior-oriented value. Research findings indicate that above all, there are differences in preferences depending on characteristics of fashion jewelry design depending on consumption value. It was found that there are differences in preferences depending on numbers of setting of fashion jewelry depending on consumption value, but it was found that there are no differences in preferences depending on jewelry materials. In addition, it was observed that for color characteristics of fashion jewelry, there are differences in preferences depending on consumption value. There are differences in preferences for fashion jewelry depending on consumption value, which indicates that preferences for products change depending on consumers' consumption value rather than use value. And it can be an explanation for this reason. Therefore, it is necessary to work out a more efficient strategy through a process of setting up a target according to consumption value.

Increase in oil prices and building energy consumption has been a great burden for Korea which has significant energy dependence on foreign energy sources. In this context, reduction of building energy consumption, which comprises 40% of total energy consumption, is a very important issue. This research therefore empirically analyzed a hospital "P" that implemented ICT-based energy consumption and cost reduction initiative. The hospital first replaced existing water absorber for heating/cooling air and boiler for heating water with water heat storage heat pump system. This was accompanied by subscribing to different electricity price plans to maximize cost reduction. Secondly, the hospital additionally applied ICT-based optimized control algorithm that considers surrounding factors (external temperature, changes in energy demand). The analysis of these mechanisms indicate that the ICT-based energy consumption and cost reduction initiative for hospitals can reduce energy consumption by 53.6% with replacement of low-efficiency equipment and additionally by 18.2% with optimized control algorithm. The mechanisms will provide energy consumption reduction opportunities for other hospitals and buildings with high energy consumption.

The purpose of this paper is to investigate motivational factors and consequence of the herd behavior of adolescent consumers under the buying decision process in the connected era of internet. For such purpose, this study built a research model and examined how sensitivity to fads, interaction and inaccuracy affect the disequilibrium consumption of adolescents. We also examined the relationship between disequilibrium consumption and consumption happiness. The survey method was used for this paper, and data from a total of 142 students were used for the analysis. And structural equation model was used to analyze the data. The results of this empirical study is summarized as followings. First, sensitivity to fads and interaction have direct effect on the disequilibrium consumption of adolescents. Second, disequilibrium consumption has a positive effect on adolescents' consumption happiness. This implies that the importance of herd behavior in designing rational choice in adolescents' consumption behaviors.

In this paper, we proposed FPGA algorithm for consider the power consumption. Proposed algorithm generated a feasible cluster by circuit partition considering the CLB condition within FPGA. Separated the feasible cluster reduced power consumption using glitch removal method. Glitch removal appled delay buffer insertion method by signal process within the feasible cluster. Also, removal glitch between the feasible clusters by signal process for circuit. The experiments results show reduction in the power consumption by 7.14% comparing with that of [9].

In this paper, proposed the method to increase the battery life of the Wibro terminal by reducing its power consumption. The amount of power consumption was analysed. And as the results, it is shown that the suggested method can be reduced the power consumption. The performance of the proposed system, which control the number of pilot of symbol, analysed by the simulation. It is shown that the power consumption of the terminal can be reduced by the reduction of the CINR for the percentage of pilot per symbol, as 0.48dBm for 10% and 0.95dBm for 20%, which can be accomplished by changing the current system of having the fixed number of pilot.
