Optimal allocation of viewers on a terrain in such a wav that the hidden area would be minimized has many practical applications. However, it is impossible in practical sense to evaluate all the possible allocations. In this paper, we propose an optimal allocation of viewers based on genetic algorithm that enables probabilistic search of huge solution space. An experiment for one and three viewers was performed. The algorithm converges to good solutions. Especially, in one viewer case, the algorithm found the best solution.

As the representative of the convergence of broadcasting and communication, the data service was expected to be a new profit source of the related industries. The data service, however, has not satisfied the expectation due to the short of killer services that make it popular with the viewers. According to the several survey reports, a lot of viewers do internet-searching using the key-words related to the TV program they are watching and, with the faith in the survey results, several trials has been performed to port established PC-based searching systems onto TV-set only to fail to get popularity among viewers. The failures are mainly caused that they did not sufficiently consider the viewers' modality that viewers seriously want not to be obstructed by anything when they are absorbed in a program. This paper proposes an MHP-based searching data service designed to minimally interrupt the viewers watching a TV program and to be synchronized with a TV program by using the searching key-words relative to it, the content of which changes as time goes on.

This study was conducted to examine the interrelations among snack preference, purchasing behavior and intake of fifth and sixth grade students in elementary schools in Gyeongnam province. Frequency of snack intake was the highest in those who reported 'once a day' (45.6%) snack habit. Longer-time television viewers also showed higher frequency of snack intake than shorter-time viewers. Thirty-three percent of students purchased snacks by themselves and the frequency of snack purchasing had a significant positive relationship with TV watching time (p < 0.01). The main reason, place and time of eating snacks were 'hunger' (79.2%), their home environment (50.9%) and 'after school hours' (89.7%). The favorite snack was 'ice cream' and, this snack habit was significantly different by gender of the child (p < 0.01) and TV watching time (p < 0.01). 'Milk and dairy products' scored highest (3.47) in snack intake frequency among longer-time TV viewers (> 2hr) compared to shorter-time TV viewers and this difference was statistically significant (p < 0.001). The snack preference score was correlated positively (r = 0.454) with the intake frequency for snack and its explanation power ($R^2$) was 20.5%. With regard to snack purchase behaviors, the scores of 'checking the expiration date' and 'comparing the price with similar products' were high (in what group?). Female students (p < 0.001) and shorter-time TV viewers (< 2hr) (p < 0.01) had a more reasonable purchasing behavior. The total score of preference was significantly higher (p < 0.05) in shorter-timeTV viewers (< 2hr). In the correlation between snack purchasing behaviors and intake frequency, attractiveness (r = 0.208, p < 0.001) and preference (r = 0.330, p < 0.001) showed significant positive correlations. The result of regression analysis, preference only was selected ($R^2$= 0.108).

YouTube has become a popular platform for vlogs. Among various forms of vlogs, office worker vlogs, in which a person engaged in a specific job shows his/her work environment and daily routine, are gaining popularity. Thus, focusing on office worker vlogs, the present research investigates the effects of office worker vlogs' characteristics (i.e., vlog content characteristics, vlogger characteristics) on the YouTube viewers' educational value of the vlog and their job engagement. Specifically, this research examines whether(1) vlog content characteristics (i.e., usefulness, accessibility, and vividness) and (2) vlogger characteristics (i.e., job similarity, credibility, and expertise) influence the YouTube viewers' educational value of the vlog. Moreover, this research examines how the YouTube viewers' educational value of the vlog affects their job engagement. With a sample of YouTube viewers of office worker vlogs (N = 215), structural equation modelling was implemented to investigate the relationships in the proposed model. The results indicate that (1) perceived usefulness of the office worker vlog is positively associated with the educational value of the vlog; (2) perceived accessibility of the office worker vlog is positively associated with the educational value of the vlog, albeit marginally significant; (3) perceived vividness of the office worker vlog is positively associated with the educational value of the vlog; (4) perceived job similarity to the office worker vlogger is positively associated with the educational value of the vlog; (5) perceived credibility of the office worker vlogger is positively associated with the educational value of the vlog; (6) perceived expertise of the office worker vlogger is positively associated with the educational value of the vlog; and (7) the educational value of the office worker vlog is positively associated with the YouTube viewers' job engagement. The findings provide important implications for the production and use of office worker vlog contents.

The Korean film has not been on the board of Korean waves due to the limitation of the media accessibility. However, N-screen gives Korean films the chance of being on the board of Korean waves, especially in Asian country which have shared cultural codes. This study aims to demonstrate the possibility of Korean films in asia based on the analysis of Korean film viewers' motivation and media usage. For this purpose the 330 data were collected among Korean, Japanese and Chinese from Feb, 23rd through April, 5th in 2013. The results show the followings; 1) Korean viewers have the strong preference of cinema theater to other media such as PC, VCR/DVD player, tablet PC and mobile phones. Whereas, Japanese viewers prefer VCR or DVD players and Chinese viewers prefer PC and mobile phones. 2) In terms of viewing motivation, social utility is most important to Korean viewers while diversion to Japanese and Chinese viewers.

Many stars are delivering various contents such as real time talks through Internet personal broadcasting to communicate with fans. For stars and entertainment companies that expect the effect of communicating with fans through Internet broadcasting, it can be said that it is important to grasp viewers' viewing motivation and satisfaction. Thus, we analyzed the viewing motivation and satisfaction of Chinese viewers' Internet personal broadcasting of famous celebrities based on the uses and gratifications approach. To this end, an online survey was conducted, and as a result, 'emotional motivation' and 'functional motivation' were found as Chinese viewers' motivation for viewing Internet personal broadcasting of famous celebrities. In addition, it was found that viewers' satisfaction increased as the viewers' 'emotional viewing motivation' increased. From the results of this study, it seems that a strategy of subdividing programs by reflecting the audience characteristics such as age and occupation is needed. It can be a way to expand the number of viewers and the intended broadcasting effect by designing and producing programs for personalized celebrity internet broadcasting by segmenting audiences.
