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: The purpose of this study was to understand and describe the leadership experience of clinical nurses. Methods: During 2014, data were collected using focus group interviews. Three focus group interviews were held with a total of 20 clinical nurses participating. All interviews were recorded as they were spoken and transcribed and data were analyzed using qualitative content analysis. Results: Fifteen categories emerged from the five main themes. 1) Thoughts on the leadership category: to lead others, to cope with problem situations adequately and to serve as a shield against difficulties. 2) Situations requiring leadership: situation that requires correct judgement, coping and situations that need coordination and cooperation. 3-1) Leadership behaviors: other-oriented approach and self-oriented approach. 3-2) Leadership behavior consequences: relevant compensation and unfair termination. 4-1) Facilitators of leadership: confidence and passion for nursing and external support and resources. 4-2) Barriers to leadership: non-supportive organization culture and deficiency in own leadership competencies. 5) Strategies of leadership development: strengthen leadership through self-development and organizational leadership development. Conclusion: In conclusion, the results indicate that it is necessary to enhance clinical nurses' leadership role in healthcare. Enhancement can be achieved through leadership programs focused on enlarging leadership experience, constant self-development, leadership training, and development of leadership competencies suited to the nursing environment.

Purpose: The purpose of the study was to understand and describe the hospital workers' experience related to the hospital evaluation program implemented in Korea between 2004 and 2009. Methods: During 2010, data were collected using focus group interviews. Four focus group interviews were held with a total of 28 hospital workers participating. All interviews were recorded and transcribed as they were spoken, and data were analyzed using qualitative content analysis. Results: Nine themes emerged from the analysis: 1) Positive change in the necessity of the evaluation; 2) Improvement in the hospital system, facilities, and human resources; 3) Unity through cooperation among departments; 4) Nursing work overload; 5) Lack of physicians' awareness and responsibilities; 6) Unfair and unrealistic evaluation items; 7) Lack of credibility of the outcome; 8) Shifting responsibility for negative outcomes to the workers; 9) Lack of pragmatic utility. Conclusion: The results of the study demonstrate that the hospital evaluation program played a key role in improving some work environments and communication among departments. At the same time, they show various negative themes resulting from the context of very authoritarian hospital systems and a connection-oriented society in Korea.

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.

구어 연구에서는 음성 데이터를 문자로 옮기는 전사(Transcription)라는 과정이 필요하다. 전사 작업을 보조하는 프로그램을 전사도구라고 하는데, 발화 내용을 비롯하여, 발화 시간, 화자 정보 등의 많은 정보를 기록하는 다양한 기능을 제공한다. 이로 인하여 컴퓨터 사용에 익숙하지 않은 사용자는 숙지하는데 어려움이 있다. 또한 전사 도구는 국내에서 개발된 것이 거의 없어서 한국어 환경에 적합하지 않는 경우가 많다. 본 논문에서는 효율적인 한국어 전사를 지원하면서 비숙련자도 도구를 쉽고 빠르게 적응할 수 있는 전사 도구를 제안한다. 이를 위해 비숙련자를 위한 사용자 친화적인 인터페이스 환경을 제공한다. 또한 전사 과정에서 발생할 수 있는 실수를 최소화하기 위해 전사 지원 기능을 제공한다. 마지막으로 데이터 신뢰성을 위한 시스템 구조를 제공한다. 제안하는 도구에 대해 전사 경험의 유무에 따라 사용성 평가를 하였으며, 평가결과는 전체적으로 전사 속도 향상 및 전사 지원 기능이 편리한 것으로 나타났다.

본 연구의 목적은 요양병원 입원 노인의 성공적 노화에 대해 간호사가 어떻게 인식하는지를 파악하여 서술하는 것이다. 자료 수집을 위해 2016년 포커스 그룹 면담을 이용하였다. 포커스 그룹은 3개의 요양병원에 각각 1개씩의 포커스 그룹을 구성하여 총 3개의 포커스 그룹을 운영하였으며, 전체 14명의 간호사가 대상자로 참여하였다. 모든 면담 내용은 녹음하여 참여자가 말한 그대로 필사하였으며, 자료는 질적 내용분석을 이용해 분석하였다. 연구결과 25개의 개념이 확인되었으며, 15개의 하위범주와 5개의 범주가 도출되었다. 간호사가 인식하는 요양병원 입원 노인의 성공적 노화에 대한 5개 주요 범주는 "요양병원 삶에 익숙해지기", "주어진 상황에서 긍정적으로 살아가기", "주변과 소통하고 관계 형성하기", "가족의 관심과 지지 받기", "경제력 유지하기"로 나타났다. 요양병원 입원 노인의 성공적 노화를 위해 향후 요양병원에 입원한 노인을 대상으로 성공적 노화에 관한 심층적인 질적 연구를 수행하여 본 연구 결과와 비교 분석하고, 연구 결과를 바탕으로 요양병원 장기 입원노인의 성공적 노화를 위한 프로그램 개발 및 적용이 필요하다고 본다.
