The paper presents a novel embedded multifunctional media sever (EMMS) for mobile devices to receive various media programs. Being different from other contemporary system research, the paper mainly studies how to design a reception solution for terrestrial digital television (DTV) on mobile devices and how to enable mobile devices can receive DTV program, enjoy video-on-demand (VOD), achieve video surveillance and relay Internet video program via local Wi-Fi simultaneously. In the system design, we integrate broadcasting-terrestrial DTV tuner, streaming media re-transmission system, VOD disk, video camera and access interface to the Internet into EMMS, which can either receive terrestrial DTV radio signals and demodulate out digital transport stream (TS), or can read streaming media bit-stream from VOD disk, surveillance camera or access interface to the Internet. The experimental results show the proposed system is stable and quality-efficient. Comparing with the other systems, the proposed system has the least packet loss rate and response time.

The two objectives of this study were 1) to develop an efficacy expectation promoting program for the management of menopause based on the self-efficacy theory of Bandura(1977), and 2) to investigate the effects of the efficacy expectation promoting program for the management of menopause. The first phase was to development an efficacy expectation promoting program through video tape. A telephone coaching program served as a follow-up to the efficacy expectation promoting program which provided encouragement and support to the subjects. The second phase was the experimental stage. This experimentation was conducted to determine whether an efficacy expectation promoting program based on theory of Bandura would increase the self-efficacy and the management of menopause. Results : The video which we developed consisted of 2 parts. Part one discussed the symptoms and the management of menopause. Part two reflected the vicarious step-by-step success of middle-aged women's menopause management. The telephone coaching program served as a follow up to the efficacy expectation promoting program and provided encouragement and support to the subjects. The total length of the video is 50 minutes. The hypotheses stated in phase two were supported by following results : In the two experimental groups consisting of the natural and artificial menopause groups both demonstrated significant increase in their general and concrete self-efficacy scores. In the experimental groups, both the objective and subjective menopause management scores increased n the natural and artificial menopause experimental groups. In conclusion, it was found that an efficacy expectation promoting program was an effective nursing intervention for increasing self-efficacy and management of menopause.

The study examined the effects of an intervention program for improving mother-child interaction behaviors of mothers with developmentally delayed young children. The program consisted of three main activities, lectures for good parenting, video-feedback of mother-child interactions, and consultation for problem behaviors of children. The subjects were 4 mothers of 5-6 years old children with developmental delays who were referred to a social competence program of a child counseling center. The mothers were identified to have problematic mother-child interaction behaviors through clinical interviews. The program ran for 16 sessions, one parent group leader implemented each session for 90-120 minutes once a week. The videotaped data of mother-child interactions for 10 minutes every 4 sessions were estimated by Maternal Behavior Rating Scale(MBRS) and qualitatively analyzed by transcription of communications between mothers and their children. It concluded that the intervention program enhanced mother-child interaction behaviors.

The purpose of this study was to investigate the effects of smart phone video educational program on disease-related knowledge and anxiety in patients with coronary artery disease. A quasi-experimental study used a non-equivalent control group pre-post test design. A smart phone video educational program was developed and offered to the experimental group. Participants were drawn from a inpatient ward. Twenty eight were selected for the experimental group while 30 were assigned to a control group. The results of this study were as followed: Disease-related knowledge in the experimental group showed a significant increase after smart phone video education compared with the control group. But the score of anxiety did not show a significant difference between experimental and control group. Thus, it is necessary to develop interventions considering both educational and psychological factors at the same time for the patients with coronary artery disease.

Purpose: This study was conducted to identify the effects of educational video program delivered using Tablet PC on physical discomfort, uncertainty, state anxiety, and nursing education satisfaction among early gastric cancer patients undergoing endoscopic submucosal dissection. Methods: The study design was nonequivalent control group pretest-posttest design. The subjects were 60 patients who were hospitalized to undergo endoscopic submucosal dissection. The experimental group watched educational video using Tablet PC (n=30) and the control group received only the usual education (n=30). The collected data were analyzed using independent t-test to examine study hypothesis. Results: The level of physical discomfort (t=3.05, p=.003) and nursing education satisfaction (t=-2.20, p=.032) in the experimental group were significantly different from that of the control group. However, the level of uncertainty (t=-0.82, p=.418) and state anxiety (t=-1.69, p=.097) in the experimental group were not different from that of the control group. Conclusion: The study findings confirm that the educational video program delivered using Tablet PC as an effective intervention alleviating physical discomfort and improving satisfaction regarding nursing education among early gastric cancer patients undergoing endoscopic submucosal dissection. Based on the findings, we believe that the educational video program can be helpful in decreaseing physical discomfort, and it also can be utilized to improve nursing education satisfaction.

This paper explores the current situation of the broadcasting program production by video journalists (VJs), one of the recent trends of broadcasting production, centering around the programs made in Daejeon. The result of the survey shows that VJ programs are considered to be one of the generalized broadcasting program production systems. Thus, production costs should be γeadjusted to a realistic level in order to secure the good quality VJ programs in the current situation. Local broadcasting stations should depart from the idea that they make a VJ program subcontract to produce programs at low cost. It is time to support good quality VJ programs financially and systematically. The survey also reveals that most video journalists cannot participate in the decision-making process regarding program production. Local broadcastings should cooperate with video journalists, as co-producers, in producing the programs. Besides, VJ programs have some disadvantages such as limitation of high definition image production, poor image quality, instability of images taken, etc Hence, video journalists should also try to make better image quality of their broadcasting programs. Local subcontractors should make efforts to overcome their poor manpower and production environments as well. By economizing their scale of production and updating their production equipment, subcontractors need to constantly develop the contents related to local community which make them more competitive.

This study was conducted to investigate the effects of video - based movement therapy program on emotional variables (anxiety, depression, panic disorder) and EEG on panic disorder patients. The following conclusions were obtained. The results of the 12 - week video - based behavior therapy program showed that there were statistically significant differences (p <.05) in the anxiety scale of the exercise group. There were statistically significant differences (p <.05) between the left brain L-Beta region of the exercise group and the left brain H-Beta and the right brain L-Beta regions of the control group and no significant difference was found between the groups. The results of this study suggest that the performance of the video-based behavioral therapy program for panic disorder patients did not affect the emotional variables and EEG changes. However, in the case of emotional variables, It is considered that the longer the program execution period, the more result will be obtained. In addition, it is expected that more positive study results can be expected if the program is run after having had enough familiarity and adaptation time of the operation treatment program omitted in this study.

A conventional CBR channel is now capable of delivering several digitally compressed video programs due to recent advances in video compression, such as MPEG-2, and digital transmission technology. This paper presents a joint video coding scheme that is to maintain a constant sum of bit rates for all the programs but to allow the variable bit rate for individual program in the transimission environment mentioned above. Thus advantages of VBR video compression can be obtained. This paper contributes in two aspects. First, a rate-distortion estimation method for MPEG-2 video is proposed, which enavle us predict the amount of bits and the distortion generated from an encoded picture at a given quantization step size and vice versa. The most attractive features of the proposed rate-distortion estimation method are its accuracy and a computational complexity low enough to be applied to real-time video coding applications. Second, this paper presents an efficient and accurate joint rate control scheme using the rate-distortion estimation results and verifies its performance with experiments. The experimental results show that our coding scheme gives a significant gain even though a small number of video programs are coded jointly. For example, a stable picture quality is maintained among the video programs as well as within a program, and additional extra programs can be transmitted over the same channel bandwidth if the proposed joint video coding scheme is used.
