The purpose of this study was to examine the effects of self reflective practice using cellular phone video recordings on self-confidence in performance, practice satisfaction, learning self-efficacy and core basic nursing skills achievement. A quasi-experimental study with a non-equivalent control group posttest design was used. Participants were recruited from one nursing colleges. The sample consisted of an experimental group (n=43) that participated in the self reflective practice using cellular phone video recordings program and a control group (n=43). The data of self-confidence in performance, practice satisfaction, and learning self-efficacy were collected using self-administered questionnaires from March 2, 2018 to May 30. The core basic nursing skills achievement was evaluated by two researchers. Data analyzed using ${\chi}^2$-test and independent t-test. After the intervention, self-confidence in performance, learning self-efficacy and core basic nursing skills achievement significantly increased in the experimental group compared with the control group. Findings indicated that, this program can be recommended as an effective educational program for the nursing student to improve their fundamental nursing skills.

The purposes of this study are to experiment a modified domestic conflict containment program (DCCP) which was initially development for developed by Dr, Neidig on 10 Korean offenders, and to provide practical basement for development of Korean offenders' group. This modified group program is based on cognitive-behavioral and communication theories. The group was leaded by 2 therapists, one female and one male, and continued 12 consecutive weeks, each week for 2 1/2 hours. The evaluation on the program is based on 4 different data: 1) intake form for spouse abuse, 2) group leader's summary on each session based on video taping and an analysis after each session with two probation officers in charge for the offenders, 3) clinical measurement for self esteem (ISE), 4) daily self report on each session and the final evaluation form by the group members. The result was shown consisently that this program achieved the purpose of this study across the all 4 data. Therefore, we suggest our experimental study will be able to provide a practical basement for future development of group treatment model for Korean offenders.

The effects of the Attachment Promotion Therapy (APT) program for the autistic children were reviewed by 8 papers. The program was consisted with play activity centered mother-child interaction, educational activity for parents, lecture, video-feedback, and support. APT program was effective to improve the attachment behaviors and attachment security. And the mother's behaviors to her child became more child-centered, positively responsive, expressive supportively. Ninety six point seven percent of the mothers were satisfied with the APT program. They described that it was helpful to understand their children's developmental limitation and strength, to learn how to play with their children, to make supportive social network among the mothers, to minimize familial conflicts, and to make them much more comfortable with their children. They thought the APT Program was to be a steppingstone of the further educational program. APT program is an effective early intervention to promote social development and decrease autistic problems.

Purpose: Family-caregivers of stroke patients usually go through hardship and life style changes during the protracted course of a family member's rehabilitation. There is need for programs to educate family-caregivers to better manage the medical crisis. In this study an evaluation was done of the degrees of burden and well-being experienced by primary family-caregivers following video-guided education (VGE) on rehabilitation and family lifestyle changes. Method: Fifty-eight primary family-caregivers of stroke patients on a neurological ward were divided into VGE (29) and control (29) groups. VGE was started within 7 days of patient admission. Interventions included VGE, counseling, and demonstration - re-demonstration. The control group received standard education but not VGE. Data were analyzed using Chi-square test, t-test, ANCOVA, and Pearson correlation coefficients with the SAS program. Results: The VGE group had a significantly lower score for total burden (F=7.19, p=.010) and for sub-scale of time-dependent burden (F=8.44, p=.005) than the control group. There was a negative correlation between primary family-caregiver burden and well-being (r=-.7151, p<.001). Conclusion: Results suggest that the rehabilitation program using VGE was an effective nursing intervention to reduce the burden of primary family-caregivers of stroke patients.

The purpose of this research aims to find the changes resulted from the collaboration of colors, harmonies, and dynamics within a music. Through this research model, psychologically change of color and harmony, dynamics have explored to collect the resources for the research of the visual media music therapy program. In video media, music is utilized as non-verbal communication in many areas. The connection between melodies and colors, especially, is one of the most effective instrument to reduce the gap between realities and imagination, thus leading emotional inspiration. Gim's(Guided Imagery and Music) model of musical therapy strives to understand inner-side of human nature, and gives an insight into self-understanding. We would like to promote active, and physical model of musical therapy aside from passive existing mode, and apply it as the base resource for our ever-changing society, and teenage education.

This paper presents a high-speed intrusion detection process for multi-core video surveillance systems. The high-speed intrusion detection was designed to a parallel process. Based on the analysis of the conventional process, a parallel intrusion detection process was proposed so as to be accelerated by utilizing multiple processing cores in contemporary computing systems. The proposed process performs the intrusion detection in a per-frame parallel manner, considering the data dependency between frames. The proposed process was validated by implementing a multi-threaded intrusion detection program. For the system having eight processing cores, the detection speed of the proposed program is higher than that of the conventional one by up to 353.76% in terms of the frame rate.

In digital broadcasting, services such as digital satellite TV, cable TV and digital terrestrial TV, several video programs are compressed by MPEG-2, and then simultaneously transmitted over a conventional CBR (Constant Bit Rate) broadcasting channel. In this paper, we propose a joint quality control scheme to be able to accurately control the relative picture quality among the video programs, which is achieved by simdt;,nL'Ously controlling the video encoders to generate the VBR (Variable Bit Rate) compressed video streams. Our quality control scheme can prevent the video buffer overflow and underflow by total target bit allocation process, and also exactly control the relative picture quality in terms of PSNR (Peak Signal to Noise Ratio) between some programs requiring higher picture quality and others by rate-distortion modification. Furthermore we present a rate-distortion estimation method for MPEG-2 video, which is base of our joint quality control, and verify its performance by experiments. The most attractive features of this estimation method are as follows: 1) computational complexity is low because main operation for the estimation is to calculate the histogram of OCT coefficients into quantizer; 2) estimation results are very accurate enough to be applied to the practical MPEG-2 video coding applications. Simulation results show that the proposed joint quality control scheme accurately controls the relative picture quality among the video progran1s transmitted over a single channel as well as provides more consistent and higher picture quality than independent coding scheme that encodes each program independently.

비디오 프레임 내의 오버레이 텍스트는 음성과 시각적 내용에 부가적인 정보를 제공한다. 특히, 뉴스 비디오에서 이 텍스트는 비디오 영상 내용을 압축적이고 직접적인 설명을 한다. 그러므로 뉴스 비디오 색인 시스템을 만드는데 있어서 가장 신뢰할 수 있는 실마리이다. 텔레비전 뉴스 프로그램의 색인 시스템을 만들기 위해서는 텍스트를 검출하고 인식하는 것이 중요하다. 이 논문은 뉴스 비디오에서 오버레이 텍스트를 검출하고 인식하는데 도움이 되는 오버레이 텍스트 시작 프레임 식별을 제안한다. 비디오 시퀀스의 모든 프레임이 오버레이 텍스트를 포함하는 것이 아니기 때문에, 모든 프레임에서 오버레이 텍스트의 추출은 불필요하고 시간 낭비다. 그러므로 오버레이 텍스트를 포함하고 있는 프레임에만 초점을 맞춤으로써 오버레이 텍스트 검출의 정확도를 개선할 수 있다. 텍스트 시작 프레임 식별 방법에 대한 비교 실험을 뉴스 비디오에 대해서 실시하고, 적절한 처리 방법을 제안한다.

Terrestrial digital multimedia broadcasting(T-DMB) is one of mobile broadcasting services, and the commercial service was started in December 2005 in Korea. The performance targets of T-DMB are providing VCD(video CD) quality video and FM radio quality audio. In recent years, the researches for providing high quality video or audio service on T-DMB environments have been being carried out. To provide high-quality video or audio service, some additional data should be transmitted to the receiver as well as T-DMB video and audio data. Since the data rate for one T-DMB program is low, it is important to transmit the additional data at a low bit rate. In this paper, we propose a packetizing method for efficient transmission of the additional data to provide multichannel audio service on T-DMB environment.
