This study aims to analyze the usage behavior of e-government service users based on the e-government maturity model and provide suggestions for advancement of the e-government services. The changes in Korea's e-government services were analyzed as follows; 1) Proportion of use of e-government services in Korean public services, 2) E-government service types/stages use, 3) Service use by platform 4) User response to e-government service 5) Users' requests for future e-government service usage methods. For the analysis, this study used data from Korea's 2012-2020 e-government usage behavior survey data. As a result of the analysis, first, the proportion of e-government service has been continuously increasing, and second, the use of the e-participation stage is relatively low compared to the presenting information, interaction, and transaction stages. Third, by platform, e-government service has been expanded to various access platforms such as mobile, kiosk, and SNS centering on the web. Fourth, users' satisfaction with e-government service is very high. However, to vitalize e-government services, users requested improvements such as providing one-stop integrated services and simplifying authentication procedures. Based on the analysis results, this study 1) reflects the user's point of view in the maturity model of e-government, 2) considers access to various platforms according to the development of digital technology, 3) improves the e-government maturity model through data-based analysis such as user usage behavior suggested the need.

In digital broadcasting, applications are computer programs executed by the set-top box(TV receiver) , and synchronized applications are those that perform tasks at the specified moments in the underlying video. This paper describes important concepts, standards, and skills needed to implement synchronized applications and explains how to integrate them to implement these applications. This Paper assumes the European data broadcasting standard, DVB-MHP. In DVB-MHP, scheduled stream events are recommended as a means of synchronizing applications with video streams. In this method, the application receives each stream event, and executes the action associated with the stream event at the time specified in the stream event. Commercially available stream generators, i.e., multiplexers, do not generate transport streams that support scheduled stream events. So we used a stream generator implemented in our lab. We implemented a synchronized application where the actions triggered by stream events are to display graphic images. We found that our synchronized application processes scheduled stream events successfully. In our experimentation, the stream events were synchronized with the video and the deviation from the intended time was within 240 ㎳, which is a tolerance for synchronization skew between graphic images and video.

Purpose: The purpose of this study is to investigate systematic and comprehensive explanation about safety behavior by applying integrated model of Theory of Planned Behavior (TPB) and Social Cognitive Theory (SCT). By showing the interrelationship of effects of factors affecting safety behavior in a single model, comprehensive understanding regarding safety behavior will be possible. Research design, data, and methodology: This study try to integrate the two theory, TPB and SCT, to introduce background factors, such as safety culture, affecting cognitive factors of subjective norm, safety attitude, perceived behavioral control, safety consciousness, which are again affecting behavior intention of the TPB. We composed 73 questionnaire to analyse the relationship among factors affecting safety behavior. The questionnaire were distributed to stewards and stewardesses of KAL, ASIANA, and LCCs. 422 were collected and used for analysis. Factor analysis, regression analysis, and control effect analysis were conducted using SPSS windows version 2.0. Results: The safety culture, safety atmosphere, and safety education/training were turned out to affect subjective norm, safety attitude, perceived behavioral control, safety consciousness. And the cognitive factors also showed to affect safety intention significantly. The results that safety intention affects safety behavior was found. Also there are control effect of cost consciousness and punishment while safety intention affects safety behavior. Conclusions: Safety is the virtue that should be given first priority to in our daily life. To secure safety, everyone in an organization should have high level of safety intention and conduct safety behavior. The study results provide systematic and comprehensive understandings on the relationship among factors affecting cabin crews' safety behavior. The results will help design safety related regulations, education/training, and support employees to engage in safety behavior related activities.

This study reviewed reorganization of bureaucrats in the beginning of Lee Myung bak's government from the perspective of the relationship between politicians and bureaucrats. In other words, it analyzed the reorganization of central office group of Korean government in 2008 as the relationship between calling to account by politicians and avoiding calling to account by bureaucrats. Conclusively, first, separation or abolition of a certain organization was resulted from calling to account by president (the ruling party). Second, merging organizations was done because president wanted strong control on that agency or he wanted to realize presidential election pledge (policy) through the agency. Third, if an organization was not changed even though it was selected as the target of abolition, it meant that the organization succeeded in defense. As seen from the above cases, it was found that politicians and bureaucrats played a kind of game for reorganization of government organizations. First of all, if politicians succeeded in calling to account, the bureaucratic organization was separated or abolished. If bureaucrats succeeded in self defense, the organization became expanded. Finally, if both parties were even, corresponding organizations would not have changes.

This article attempted to apply the methodology of film acting as a performance oriented towards socio-cultural meaning to Min-sik Choi's acting. Specifically, the relationship between the body, the face, the audio, the direction and the attitude toward film technology mentioned in the interview dictation of actor Choi Min-sik was analyzed. In conclusion, Min-sik Choi's acting cannot be defined only by method acting, but implies or integrates the typical or avant-garde acting theories such as Stanislavsky, Strasberg, Mayerhold, Brecht and Grotovski. Above all, it is the presentation that expresses the flow of life through movement suggested by S. Kracauer. The feeling of compassion that Choi Min-sik himself emphasizes is in contact with the essence of the film that reproduces the flow of life, and it expands to an intended screen performance with a certain purpose. The screen performance that can be compressed with compassion and the flow of life is expressed by Min-sik Choi's various personas. His persona, transcending good and evil, reflects the present of Korean society.

This driving simulation study examined relative differences in driving anger as the functions of drivers' gender and driving experiences, and actor-observer perspectives when they were exposed in two anger-provoking driving scenarios(cutting-in and sudden stop). The results showed the followings. First, neither drivers' gender nor driving experience, when they were considered independently of the driving situation types and actor-observer perspectives, yielded significant difference in driving anger. Second, actor-observer effect on driving anger was observed only in the cutting-in condition where other driver's intension was emphasized. Third, the female drivers of low driving experience tended to show the strongest tendency of actor-observer bias in the cutting-in condition. These results suggested that the levels of driving anger as the functions of drivers' gender and driving experience can be differed by types of driving situation as well as perspectives of drivers' interpreting the situations.
