한국어 text - to - speech 합성기의 구현
이정석(Lee JungSuk),오영환(Oh Yung Hwan) 한국정보과학회 1992 한국정보과학회 학술발표논문집 Vol.19 No.1
최근, 음성에 의한 man - machine 인터페이스를 위해 음성인식 및 음성 합성기술에 관한 관심이 고조되고 있다. 특히 음성합성은 무인안내시스템을 비롯한 광범위한 응용분야를 가지고 있어 실용화가 시급한 분야이다. 한국어의 합성을 위한 연구는 몇 곳에서 이루어지고 있으나 아직 만족할만한 성능의 시스템은 나타나지 않고 있다. 본 연구에서는 한국어에 나타나는 모든 음소환경에서의 각 음소의 음향학적인 분석 데이타를 이용하여 text - to - speech 형 합성기의 prototype을 구현하였다. 시스템은 한글 텍스트를 받아들여 음소열로 바꾸는 전처리부분과 음소의 열에서 합성기의 입력 파라미터를 생성하는 두 부분으로 구성하였다. Klatt가 제안한 포만트 합성기를 사용하여 음성 샘플을 생성한 다음 DT2801보드를 이용하여 스피커로 출력하였다.

Purpose: The National Health Insurance Service implemented a tele-consultation pilot project for in-home care using Information and Communication Technologies (ICTs). This study aims to investigate nurses’, doctors’, and families’ perceptions on the project. Methods: Using the pilot project database and perception survey data, this study provides a description of the satisfaction, re-participation motivation, and experiences of nurses, doctors, and families. Results: Tele-consultation for home-visit nursing was used to monitor health conditions and problems, such as pain and blood pressure, or health counseling for home-care beneficiaries. The beneficiaries families showed higher levels of satisfaction than the service providers. Nurses and doctors had relatively positive perceptions about the usefulness of sharing information about beneficiaries, timeliness of providing nursing care, and convenience of communication. Meanwhile, nurses and doctors had negative perceptions of the sufficiency and accuracy of information obtained from tele-consultation, implying the necessity of adopting more advanced ICTs. Conclusion: This study suggests what must be considered when designing a tele-consultation service model in long-term care settings, especially in the home-visit nursing care setting. Innovative approaches using ICTs should be taken to improve home-visit nursing care quality in the era of super-aging and COVID-19.

본 연구는 장기요양 통합재가서비스 현장에서 사례관리 업무를 수행하는 통합재가기관 사례관리자들의 업무 경험을 탐색하고자 시도되었다. 이를 위해, 2022년 5월~7월 동안 장기요양기관 사례관리자 59명이 설문조사에 참여하였고, 4개 그룹 24명을 대상으로 초점집단면접조사가 실시되었다. 설문조사 결과, 대상자들은 사례관리 업무와 그에 따른 업무변화 및 효과에 관하여 긍정적으로 인식하였다. 반면, 전반적인 업무 만족도, 계속 참여 의향은 상대적으로 낮았다. 초점집단면접조사 결과, 참여자들의 사례관리 업무경험은 사례관리자의 역할과 자격, 의료·복지·요양의 협업, 국민건강보험공단·장기요양기관 합동사례관리의 세 가지 주제로 도출되었다. 이러한 연구결과를 바탕으로 향후 장기요양기관 사례관리자의 역할 강화와 사례관리 발전 전략을 제시하였다. This study was attempted to explore the work experiences of care managers of integrated home care institutions. To this end, from May to July 2022, 59 care managers of long-term care institutions participated in the survey, and a focus group interview was conducted with 24 people in 4 groups. As a result of the survey, while care managers were positively aware of the care management work and its effects, overall job satisfaction and willingness to continue participating pilot program were relatively low. As a result of the focus group interview, the care management work experience of the participants was derived from three themes: the role and qualifications of the care manager, collaboration in medical·welfare·nursing care, and joint care management with the National Health Insurance Service and long-term care institutions. Based on these research results, the strategy for strengthening the role of care managers in long-term care institutions was suggested.

Purpose: Th study is to explore the working conditions and factors related to job satisfaction of nurses in long-term care facilities for the elderly. Methods: A total of 127 nurses working long-term care facilities, from June to November 2014, completed questionnaires. Face to face interviews were conducted. The questionnaire consists of a total of 32 questions, including 5 questions related to general characteristics, 15 questions related to working conditions, and 12 questions related to job satisfaction(likert scale of 1 to 5). Results: The majority of nurses were employed in institutional care facilities, in urban area, and in privately owned facilities. On average, employed nurses worked 170.7 hours per month. Only 40.9% of them got more than two million won for their monthly salary. They were satisfied with the nature and worth of their work and the workplace relationship, but not with their wages and promotion opportunity 40.2% of nurses reported satisfaction with job. In multiple logistic regression analysis, age was a statistically significant influencing factor on general job satisfaction. Conclusion: The findings suggest that policies must be to improve nurses’ working conditions, for wages, and to support them with education and training for skills development.

Purpose: This study was conducted to explore the meaning and contents of high-quality aged care facilities and provide basic data for evaluation of service quality in such facilities. Methods: The focus group interviews and participants consisted of two user groups, for a total of 16 family caregivers of the elderly living in facilities and four service provider groups, for a total of 26 chief managers and caregivers working in aged care facilities. All interviews were recorded and transcribed as they occurred. Content analysis was used and debriefing notes were referred to in order to analyze the data. Results: Four themes of a high-quality aged care facility emerged from the analysis; 1) a place to rest for comfortable later years; 2) systematic value-based management; 3) providing professional care; 4) comprehensive service provision in response to diverse needs. Conclusion: The findings of the study showed the importance of client centered care and ethical mindset of providers, which had not been included in the existing quality evaluation programs. Based on these results, medical treatments, end-of-life care and more comprehensive and extended services including family care need to be provided in facilities to ensure good quality aged care.

The fundamental reason of noise in gear system is transmission error due to deflection of gear teeth. The vibration from transmission error moves to shaft and bearing. This vibration generates bearing force which exite gear box and finally radiate as noise outside. Therefore, studying transmission error is the most important to predict which is the fundamental reason of gear noise. In this paper, transmission error due to teeth deflection was predicted and shaft torsion was not considered in order to find only teeth deflection. For this reason, shaft was modeled as rigid, and only gear pair was modeled as flexible body. transmission error was predicted by Abaqus, FEA program, and this was compared for Spur and Helical type.
