A research model was developed in this study from previous research to illustrate the relationship among perceived scarcity, assumed expensiveness of art products, perceived functional value, perceived symbolic value as well as purchase for self and others. 639 valid cases who have experienced NFT art products have been collected for data analyses. The R software has been chosen for analysis. The results have revealed that perceived scarcity was positively related to perceived functional value and perceived symbolic value, but it was assumed that the expensiveness of art products was not significantly related to perceived functional value or perceived symbolic value. Moreover, functional value was significantly related to the purchase intention of both self and others, while symbolic value only was significantly affected by the purchase intention of others. The results of this study have provided managerial implications for future studies.

This study explores a value chain structure of TV program including news, drama, and comedy. The purpose of this research focused on factor analysis and the relationship among viewer's program selection motivations. This research explores correlation between personal value and viewing motivation. This study was to identify the value structure of respondent on TV program(news, drama, comedy) based on means-end chain theory. The research used structured APT laddering questions and 251 data was analysed. Through such analysis, category difference by stage and relationship difference were identified and hierarchical value map was compared. There are four different value ladders: first is attributes, functional consequences, psychological consequences, and final value. The result shows that on news program the basic function is viewers are want to visual factor and quickly acquire social news and they pursue a value of personal social relationship. Whereas, on drama program, the viewers are reflected by around person, and they selected a program based on closed related person. In addition, the viewers are influenced by program's social nomination, production's brand in drama, and performer's nomination, producer and program prominence on comedy. The program selection is highly correlated on program selection's credibility, vital energetic life, and social relationship. The results shows that there was no significant difference between low involvement group and high involvement group for main category involvement group respondents.

Information and communication industry, which shows rapid growth rate, is now leading the global economic growth, contributing a ripple effect on general business and economic structure. It is said that information and communication industry enables swift economic growth taking a role as a basic industry of information-oriented society. Especially, rapid technical innovation promotes mutual growth of other related industries and it is technology-intensive. The purpose of this research is to analyze the management efficiency of information and communication industry using DEA method, and finally suggest numerical value for inefficient organizations to improve their efficiency. CCR-I, BCC-I efficiency and RTS(Returns to scale) of 29 companies engaged in information and communication industry was evaluated. With the results, I suggested model companies for benchmarking in information and communication industry. To summarize, 7 companies were selected with CCR-I efficiency rate 1, and 12 companies with BCC-I efficiency rate 1. RTS was finalized with 8 IRS companies, 10 DRS companies, and 11 CRS companies.

Best value in value engineering has relation to cost and performance. But a severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient and practical methodology for accomplishing best value in construction projects is proposed. This study developed a more objective approach for performance measurement approach of mega projects and suggested a systematic process of performance quantitative analysis verifying value improvement. The proposed performance measurement method would be very useful for better communication and consensus between stakeholders and VE team especially through value engineering.

A phase-locked loop control system designed by using the linear quadratic regulator approach is presented in this paper. The system thus designed is optimal system when system is in locked state and the parameter value of loop filter which is an active PI filter can be obtained easily. By considering the structure of loop filter of phase-locked loop is included in the process to be controlled, a type 1 servo system can be constructed when voltage control oscillator is considered as an integrator. The integral gain of the proposed system obtained by linear quadratic regulator approach can be used as an optimal value to design the parameter of loop filter. The implemented result in controlling the second-order lag pressure process by using the proposed scheme show that the system response is fast with no overshoot and no steady-state error. Furthermore, the experimental results are also shown in term of output disturbance effect rejection, tracking and process parameter changed.

For last several decades, the color correction methods have been proposed for HDR(high dynamic range) images. However, color distortion problems take place after correcting the colors such as halos, dominant color as well known. Accordingly, this article presents a novel approach in which the method consists of tone-mapping method and cone response function. In the proposed method, the tone mapping method is used to improve the contrast in the given HDR image based on chromatic and achromatic based on the CIEXYZ tristimulus value, expressed in c/m². The cone response function is used to deal with mismatch between corrected image and displayed image as well as to estimate various human visual effects based on the CMCAT2000 color appearance model. The experimental results show that the proposed method yields better performance of color correction over the conventional method in subjective and quantitative quality, and color reproduction.

This study examined the effects of cultural communication on the fashion distribution type and the shopping benefit in fashion cultural complex space. Surveys period was from Sep. 17th to Sep. 21st in 2012. The Subjects of this study were the young 207 people who had shopping experiences in fashion cultural complex space in their 20s~30s. The data were analyzed by a reliability analysis(Cronbach's ${\alpha}$), factor analysis and regression analysis. The main results of this study were summarized as follows. First, cultural communication in fashion cultural complex space were impacted by cultural brand, cultural display, cultural support and beneficial effect of culture. Second, customers pursued the shopping benefits to get social value, personal pleasure, individual style and economic value. Third, the preference of fashion outlet was effected by cultural brand and cultural display. The beneficial effect of culture and cultural brand influenced on department store preference. The preference of fashion multi-brand shop was impacted by cultural brand, cultural support and beneficial effect of culture. Fourth, cultural communication in fashion cultural complex space had an effect on pursuing shopping benefits. Fifth, customer's demographic characteristics impacted on cultural brand, cultural display and beneficial effect of culture. Especially, these 3 cultural communications were effected by monthly average fashion spending than age/total income.
