Most efforts to improve tuberculosis treatment adherence target the patient and his or her behavior. This study examined the effects of behavioral modification training for these patients. Based on Bandura's behavioral principles of modeling, intervention strategies using a video program were devised to elicit specific patient target behaviors considered to improve patients' adherence to tuberculosis treatment regimens. A random assignment, two-group(experimental group and control group) research design including 81 subjects was used. The main outcomes measured were pill taking measured with the Medication Event Monitoring System(MEMS) Medication Cap, patients' self-efficacy, and their knowledge of tuberculosis. The findings are as follows : 1) There was a significant difference between the experimental group and the control group in patients' feelings of self-efficacy. That is, the patients who received the behavior modification program showed greater feeling of self-efficacy to initiate and change their behavior for the tuberculosis treatment regimen than the patients who did not receive the program(t=3.51, p=0.01). 2) There was a significant difference between the experimental group and the control group in patients' knowledge of tuberculosis. That is, the patients who received the behavior modification program showed higher level of knowledge of tuberculosis than the patients who did not receive the program(t=2.15, p=0.03) 3) There was a significant difference between the experimental group and the control group in patients' adherence to tuberculosis treatment regimens. That is, the patients who received the behavior modification program showed greater adherence to the treatment regimens than the patients who did not receive the program(t=5.11, p=0.00). The study findings provided useful insights into nursing practice, particularly in planning intervention strategies aimed at enhancing patients' adherence in tuberculosis that may also be relevant to other chronic diseases with patient adherence problems.

This paper proposes a method to classify different video contents using features of digital video. Classified video types are the news, drama, show, sports, and talk program. Features, such as intra-coded macroblock number St motion vector in P-picture in MPEG domain are used. The frame difference of YCbCr is also employed as a measure of classification. We detect the occurrences of cuts in a video for a measure of classification. Finally, back-propagation neural-network of 3 layers is used to classify video contents.

Purpose: This study explored the experiences of pregnant women with depressed mood participating in a group cognitive behavioral therapy (CBT) program using video communication, based on Beck's cognitive theory. Methods: The participants were six pregnant women out of 13 women who had participated in an 8-session group CBT program using video communication for women with depressed mood (Edinburgh Postnatal Depression score of ≥9). Data were collected from February 20 through March 25, 2021. In-depth individual interviews were conducted through a video conferencing platform at 1 month post-baseline. Thematic analysis was done. Results: Three themes, 10 subthemes, and 38 concepts were derived from experiences of participating in the 4-week group CBT program (twice a week). The first theme, entitled "continuing realization" had subthemes of "a negative and instable self," "a selfish judgment that excludes others," and "a strong belief in self-control." The second theme, entitled "attempt to change for restoration" had subthemes of "shift to rational thinking," "freedom from suppressed beliefs," "tolerance of other people," and "courage for self-expression." The third theme, entitled "departure for a positive life," had subthemes of "emotional healing," "faith in oneself," and "reestablishing the criteria for happiness." Conclusion: Pregnant women with depressed mood expressed that continuing realizations and attempts to change supported their transition toward a positive direction of healing. Thus, they were able to change their distorted thinking into rational thinking through CBT using video communication. These findings support the use of group CBT using video communication with pregnant women who have depressed mood.

Purpose: The purpose of this study was to examine the effects of a video education program in women receiving high-intensity focused ultrasound (HIFU) treatment. Methods: This was a quasi-experimental study with a nonequivalent control group non-synchronized design. The participants were 54 patients who had benign uterine tumors and adenomyosis. The data were collected from June to August 2018. A 10-minute video education program on HIFU and post-procedural care was developed based on the literature. The experimental group was provided the video education program with a question-and-answer session for 10 minutes after viewing the video. The control group received usual care (i.e., verbal instructions on post-procedural self-care). The questionnaire survey was conducted twice: before the educational program and before being discharged from the hospital. Differences in uncertainty, emotions, and self-efficacy among patients were analyzed. Data were analyzed using the chi-square test, Shapiro-Wilk test, paired t-test, and t-test with SPSS version 23.0. Results: The participants in the experimental group showed a decrease in uncertainty (t=4.33, p<.001), improvements in anxiety (t=-4.07, p<.001) and depression (t=-3.55, p<.001), and an enhancement of self-efficacy (t=-4.39, p<.001) compared to the control group. Conclusion: This nursing intervention was effective at reducing uncertainty, improving emotions, and enhancing self-efficacy. This intervention is feasible for use in nursing practice as an aid for patients when considering treatment methods.

An important aspect of video indexing is the ability to segment video into meaningful segments, i.e., content-based video segmentation. Since the audio signal in the sound track is synchronized with image sequences in the video program, a speech signal in the sound track can be used to segment video into meaningful segments. In this paper, we propose a new approach to content-based video segmentation. This approach uses closed caption to construct a recognition network for speech recognition. Accurate time information for video segmentation is then obtained from the speech recognition process. For the video segmentation experiment for TV news programs, we made 56 video summaries successfully from 57 TV news stories. It demonstrates that the proposed scheme is very promising for content-based video segmentation.

영상압축 기술의 발달과 디지털 방송을 위한 표준 확립으로 아날로그 영상의 디지털 표현과 방송이 가능하게 되었다. 현재 디지털 방송서비스를 제공하는 종합유선방송사업자들(SO : System Operator)은 고객의 기호에 맞는 방송 콘텐츠를 제공하고 있을 뿐 아니라 독자적인 방송편성을 통해 자체 제작한 방송 콘텐츠를 제공하고 있다. 자체 제작된 방송 콘텐츠의 제공을 위해서는 방송 정보의 생성과 방송 영상 데이터와의 재다중화가 필요하며 이는 현재 고가의 장비에서만 지원되고 있어 원활한 디지털 방송 콘텐츠의 제작에 어려움이 있다. 이에 본 논문에서는 디지털 방송 콘텐츠 제작 시 방송 정보를 사용자로부터 입력받아 PSIP (Program and Service Information Protocol) 정보를 생성하고 생성된 방송 영상 데이터에 PSIP 정보를 직접적으로 맵핑하는 PSIP 정보 생성 시스템을 설계 및 구현하였다.
