This paper proposes a method of player event retrieval using combination of two functions: detection of player name in speech information and detection of sound event from audio information in golf videos. The system consists of indexing module and retrieval module. At the indexing time audio segmentation and noise reduction are applied to audio stream demultiplexed from the golf videos. The noise-reduced speech is then fed into speech recognizer, which outputs spoken descriptors. The player name and sound event are indexed by the spoken descriptors. At search time, text query is converted into phoneme sequences. The lists of each query term are retrieved through a description matcher to identify full and partial phrase hits. For the retrieval of the player name, this paper compares the results of word-based, phoneme-based, and hybrid approach.

In this paper, we report our recent work on a indexing and retrieval system of broadcast news using audio content analysis. Key issues addressed in this work are two major parts of the audio indexing system: anchorperson detection based on audio segmentation, and phone-based spoken document retrieval, developed in the framework of the emerging MPEG-7 standard. Experiments are conducted on a database of Britisch broadcast news videos. We discuss the development of the retrieval system, and the evaluation of each part and the retrieval system.

Purpose: This study was conducted to identify the barriers and improvements to promoting physical activity among children using community child care centers. Methods: A qualitative research using focus group interviews was employed. Three focus group interviews were conducted with a total of 18 service providers, and open-ended questions were used. All interviews were recorded as they were spoken and transcribed and data were analyzed using qualitative content analysis. Results: Two main themes in the barriers to promoting physical activity were 'lack of resources' and 'limitations of program composition'. In addition, five sub-themes emerged as a result of analysis: 1) lack of human resources, 2) lack of finance, 3) lack of space, 4) one-off and short-term physical activity programs, 5) learning-oriented programs. Conclusion: The results indicate that it is necessary to have adequate human resources and a realistic government subsidy that allow community child care centers to provide sufficient services to children. In addition, promoting physical activity can be achieved through physical activity programs focused on peer group advisors, habituation, and development of programs suited to the needs of children and their environment.

Purpose:This study aims to understand and explore the subjective experiences of patient safety education among health care professionals in developing a patient safety curriculum in South Korea. Methods: A qualitative descriptive study was conducted through two focus group interviews in the period October-December 2018. Eleven participants who underwent patient safety education participated in each session. All interviews were recorded and transcribed as spoken, and qualitative content analysis was used to identify categories of discussion depicting participants' subjective experience with patient safety education. Results: A total of three categories and seven themes were identified out of 77 units of analysis. Topics were identified in the dimensions of a patient safety curriculum, as follows: (1) activities for patient safety; (2) principle of patient safety (five rights, ethics, patient participation) and patient participation; (3) leadership, teamwork, and communication; and (4) reporting and learning system for patient safety events. In the dimension of methods, (5) case and evidence-based education and (6) multidisciplinary and small group teaching were identified. Finally, in the dimension of the system, (7) policies for patient safety education were identified. Conclusion: Our findings indicate that patient safety education is a significant area for health care professionals. Health care professionals suggested that a systematic patient safety curriculum would improve their knowledge and attitude toward patient safety. Moreover, it enables them to better construct a safety environment in a hospital.

Purpose: The purpose of this study was to identify non-psychiatric nurses' difficulties in caring for patients with mental illness. Methods: Data were collected from eighteen general medical-surgical nurses working at a university hospital in Seoul, Korea. This study involved two focus group discussions and three in-depth individual interviews. All interviews were recorded and transcribed as they were spoken, and data were analyzed using qualitative content analysis. Results: General medical-surgical nurses experienced difficulties in 3 categories, 9 subcategories, 27 codes. The three categories were 'nurse' related factors, 'patient' related factors, 'resource' related factors. The nine categories were 'unpreparedness', 'nursing barriers due to stigma', 'undervaluing and avoidance of psychiatric nursing', 'eroding into the trap of a vicious cycle', 'facing unapproachable patients', 'dealing with unhelpful family members', 'burdening already overburdened staff', 'obstructive environment', and 'isolation of staff with heavy responsibilities'. Conclusion: The results of this study indicate the need to develop psychiatric mental health education programs for non-psychiatric nurses. Education about psychiatric mental health and support from institutions for non-psychiatric nurses can reduce their negative attitude toward psychiatric patients and difficulties in caring for psychiatric patients.

In spoken language research, transcription process needs to be carried out to translate voice data into text. Transcription tool, support program of transcription, offers various information such as content and time of utterance and speaker information. For this reason, inexperienced computer users are having trouble familiarizing with the program. Moreover, since there are little transcription tools developed domestically in Korea, they are usually not suitable for Korean environment. In this paper, we propose a transcription tool which supports not only Korean transcription but easy-to-use interface environment for novice. The transcription supporting function is also provided to minimize mistake that might happen in the process of transcription. And a system structure will be provided for data reliability. Usability of the proposed tool is evaluated in accordance with transcription experience. The evaluation result shows that transcription process and transcription support function have become faster and more convenient respectively.
