With the advent of ubiquitous computing environments, it has become increasingly important for applications to take full advantage of context information, such as the user's location, to offer greater services to the user without any explicit request. In this paper, we propose context-aware active services on the basis of CAMUS (Context-Aware Middleware for URC Systems). CAMUS is a middleware for providing context-aware applications with development and execution methodology. Accordingly, the applications developed by CAMUS respond in a timely fashion to contexts. To evaluate, we apply proposed active services to TV application domain. Therefore, we implement and experiment the TV contents recommendation service agent, control service agent and TV task based on CAMUS. The context-aware TV task is to recommend programs and control of TV according to user preference, location and voice commands.

LED backlight for LCD TV is a great alternative to CCFL backlight due to its low power consumption and flexible arrangement. Various LED backlight configurations are being used to control the backlight locally in order to achieve both power efficiency and high contrast. However, the relatively small spatial resolution of the backlight system results in showing artifacts of backlight control that is acknowledgeable to human vision. Moreover, such artifacts get worse between temporal frames. In this paper we present a method of decreasing such temporal artifacts with a Human Visual System(HVS) approach to minimize distortion caused by local backlight dimming.

An optimum pattern control procedure for the TV, FM broadcasting antennas being constructed in Seoul & Pusan is described. For the pattern control, 4 antenna elements were romoved from Seoul toward Inchen. Resulting pattern was measured and compared to the results of theoretical value. Similar results were obtained for Pusan antenna.

The inverter using level control block (LCB) was developed to drive LCD TV backlight using FFL light source. The FFL striking time, time for brightness stabilization, and lamp current of FFL backlight were shown to improve by applying LCB in the inverter. It was also shown that the stable driving of LCD TV FFL backlight with the inverter using LCB was possible over the wide temperature range.

In this parer, face recognition method which can be applied to ITCS (interactive TV control system) is proposed. We extracted ULBP(uniform local binary pattern) histogram feature from infra-red images, and we detected left-right eyes and face region by using SVM classifier. Then, We implemented face recognition system which is using Gabor transform and ULBP histogram feature and applied to personal verification for ITCS.

User's characteristics on the screen adjustment of color TV were studied. Two experiments were performed. In the first experiment, the characteristic of screen adjustment according to TV program, ambient luminance, and gender was investigated. Twenty subjects (10 females and 10 males) were participated in this experiment. Set points of brightness, contrast, tint, and color were measured on TV screen and analyzed. Brightness and contrast were significant on gender at significant level 0.01 and color was significant on gender at significant level 0.1. Tint was significant on program at significant level 0.01. The second experiment was performed to supplement the first experiment. The influences of ambient luminance, presented image, screen setting criteria, and gender were investigated. We simplified the first experiment in the second one. We restricted dependent variables (screen control variables) to only two, brightness and contrast. Other control variables were fixed to middle values. Brightness and contrast were significant on gender and screen setting criteria at significant level 0.01. In conclusion, we found that ambient luminance and presented image had no significant effects on TV screen adjustment and TV program had only a significant effect on tint. However, we found that gender and screen setting criteria had significant effects in most conditions.

This study examines the mechanism of how the dispositif, a dispositional concept of television, which is changing in form, Q-Sheet, is expressed as 'ideology' embedded in television. The dispositif implemented in television aims at the realization of mechanical desire through the internal disposition and makes the reality that it dazzles the public by adjusting the density of the gap and depreciates the existence of the aura itself. Instead of gaining new experience through the disposition, the public accepts the manipulated experience and falls into the illusion that it is true. In the television literacy program, the Q-sheet acts in the intervals and gaps that exist in the movement between the stacks, spreading the ideology, and the act of Channel Surfing by using the remote control is also a dispositf form of television viewing. In modern capitalist societies, television disposition are regenerating through proliferation and expansion, showing intent to dominate even art and culture through disposition, and autonomously injecting ideologies by television disposition.

This research sought to study viewers' perception of migrant women who wed Korean men following these women's level of specialty as shown on multi-cultural TV program by focusing on university students. Post test control group design method was utilized to conduct analysis, which demonstrates that there was a significant difference between the viewers on the professional migrant women and on the non-professional migrant women when it comes to the categories such as, 'Migrant women have specialized skills', 'migrant women have outstanding communication skills' and 'migrant women are independent minded.' Because of the existence (or non-existence) of professional careers as shown on TV program can affect viewers' perception of migrant women, it is necessary to develop measures such as development of expert group's advising system and to guarantee migrant women's diversity.

The present study was designed to investigate the effect of altruistic TV viewing and verbal training on the altruistic behavior of preschoolers. The subjects of this study were a total of 56 boys and 57 girls from a kindergarten in Kwachon, Kyung-gi do. The subjects were assigned to one of three conditions: in the first condition subjects were shown video tapes designed to portray prosocial themes (TV modeling group) ; in the second condition subjects saw the video tapes in addition to verbal training (TV modeling plus verbal training group); in the third condition subjects received neither TV modeling nor verbal training (control group). Statistical analysis was by ANOVA and $Scherr\acute{e}$ test. Significant differences were found in altruistic behavior between the TV modeling and the TV modeling with verbal training groups.
