최근 음성 인식 시스템의 성능 향상을 위해 화자 적응(speaker adaptation)에 대한 연구가 활발히 진행되고 있다. HMM 기반 인식 시스템의 모델 파라미터를 수정하는 화자 적응의 경우, MAP 방법과 MLLR 방법에 대한 연구가 주류를 이루고 있다. 두 방법은 adaptation data의 양에 따라서 서로 다른 성능을 보인다. 본 논문에서는 adaptation data의 quality를 정의하고, 이를 기존 두 방법의 가중치로 이용하여 화자 적응을 수행하는 방법을 제안한다. 제안한 방법을 KAIST 통신연구실에서 구축한 한국어 도시이름 500단어 인식 시스템에 적용하여 성능을 개선하였다.

Purpose: This study aims to examine the influence of personality types on recovery resilience and college life adjustment among dental technology students. Methods: The study recruited 165 students in colleges in some areas using convenience sampling. Data were processed through reliability analysis, frequency analysis, descriptive statistics, and correlation analysis. Moreover, linear regression analysis was performed to confirm the influence. Results: The results confirmed that the motivation for selecting a department exerted an effect on adaptation to college life and satisfaction with majors (p<0.05). Additionally, the finding indicated that personality type partially influenced resilience and adaptation to college life among dental technology students (p<0.05). Finally, the results of regression analysis on adaptation to college life found that resilience and satisfaction with majors were significant predictors of adaptation to college life (p<0.05). Conclusion: To improve adaptation to college life, increasing resilience and satisfaction with majors is necessary.

Objectives: Reportedly, the main influential factors on students' adaptation to their college life were social support, stress, adaptation resilience, self-esteem, and satisfaction with their major. This study tried to find the actual influence of these factors on dental hygiene students, and to find an intervention plan for improving their adaptation to college life and preventing their dropout. Methods: An online questionnaire survey had been conducted with 270 dental hygiene students from June 21 to July 2, 2021. The collected data were analyzed with the use of SPSS Program Version 22.0. Results: Firstly, students living together with their family, those satisfied with their major, and those doing a club activity related to their major scored high points in terms of the adaptation to college life. In addition, the adaptation points were high in those whose school entrance motivation was arbitrary, and in those who entered in the dental hygiene department in consideration of their aptitude. Secondly, college life stress was high in those whose entrance motivation was in other persons' will, those who entered in the department due to their school record and occupation, rather than aptitude, those who were also doing a part-time job, and those whose economic level was low. Thirdly, adaptation resilience, social support, and self-esteem were high in those who were highly satisfied with their major, those who entered in the department in consideration of aptitude, and those whose economic level was high. Fourthly, the biggest influential factor on their adaptation to college life was college life stress, followed by self-esteem, satisfaction with major, and adaptation resilience in order. Conclusion: Given all the results, it is necessary to analyze dental hygiene students' levels of stress, self-esteem, social support, and adaptation resilience from the beginning of their entrance, and to operate a school life adaptation program in line with school years. If any customized support and training are given to these students to deal with a variety of stress situations resiliently and wisely and achieve their jobs successfully, it is expected to improve their self-esteem and adaptation resilience, and thereby increase their adaptation to college life.

A novel envelope extraction algorithm for speech processor of cochlear implants, called adaptation algorithm, was developed which is based on a adaptation effect of the inner hair cell(IHC)/auditory nerve(AN) synapse. We achieved acoustic simulation and hearing experiments with 12 normal hearing persons to compare this adaptation algorithm with existent standard envelope extraction method. The results shows that speech processing strategy using adaptation algorithm showed significant improvements in speech recognition rate under most channel/noise condition, compared to conventional strategy We verified that the proposed adaptation algorithm may yield better speech perception under considerable amount of noise, compared to the conventional speech processing strategy.

Engineers prefer deep neural networks (DNNs) for solving computer vision problems. However, DNNs pose two major problems. First, neural networks require large amounts of well-labeled data for training. Second, the covariate shift problem is common in computer vision problems. Domain adaptation has been proposed to mitigate this problem. Recent work on adversarial-learning-based unsupervised domain adaptation (UDA) has explained transferability and enabled the model to learn robust features. Despite this advantage, current methods do not guarantee the distinguishability of the latent space unless they consider class-aware information of the target domain. Furthermore, source and target examples alone cannot efficiently extract domain-invariant features from the encoded spaces. To alleviate the problems of existing UDA methods, we propose the mixup regularization in adversarial discriminative domain adaptation (ADDA) method. We validated the effectiveness and generality of the proposed method by performing experiments under three adaptation scenarios: MNIST to USPS, SVHN to MNIST, and MNIST to MNIST-M.

Purpose: The study addressed the adaption of middle- aged Korean women to menopause, including the use of Yangsaeng, a traditional health care regimen that incorporates specific principles and methods to promote health and prevent illness, with the aim of improving health and longevity of life. Methods: Middle-aged women (40~59 years, n=171) residing in Seoul and Gyeong-Gi Province. Data was collected by using a self-reported questionnaire. Menopausal period adaptation was measured by 29 items in four categories (physical, self-concept, role function, and inter-dependent). Yangsaeng was measured by 31 questionnaire items in eight categories (morality, mind, diet, activity and rest, exercise, sleep, seasonal, and sexuality). Results: Significant differences in menopausal adaptation were evident on the basis of participant education and income. There were significant differences in Yangsaeng in terms of participant education, nature of employment, and income. Menopausal adaptation positively correlated to use of Yangsaeng. Physical adaptation, self-concept adaptation, role function adaptation, and inter-dependent adaptation positively correlated to morality Yangsaeng, mind Yangsaeng, and activity and rest Yangsaeng. Conclusion: Middle-aged Korean women who practice Yangsaeng may be better positioned to adapt to menopause. Yangsaeng may be an advantageous nursing intervention in this population.

Objectives: In this study, an analysis was performed on local government adaptation plans for climate change focusing on the health sector. The limitations of past study results have been summarized and new research subjects for preparing for the advanced second period (2018-2022) of the local government adaptation plan for climate change have been suggested. Methods: First, a review of the literature related to vulnerability assessment and adaptation plans was performed. Next, a comparison among the 16 metropolitan governments' vulnerability assessment results and adaptation plans was made. Lastly, a classification of the adaptation policy and budgets to compare with their real budget amounts was performed. Results: The results show that there is a categorizing discrepancy between vulnerability assessment and adaptation policy. In addition, their adaptation budget amounts turned out to be too large in comparison with the actual budget amounts. Conclusion: The first period (2013-2017) local government adaptation plans for climate change had some limitations. This is because there was a rapid driving force for establishing adaptation plans under the green growth strategy in Korea. Now, we are confronting a risk of adaptation to climate change. By expanding this approach, the government would be able to set up a detailed policy to improve the plans during the second period.

Methods for symbol-by-symbol channel feedback and adaptation of symbol durations have been recently proposed. In this paper, we quantitatively analyze the gain in error-constrained data throughput due to such an extremely rapid adaptation of symbol durations to fast-time-varying channels. The results show that a symbol-by-symbol adaptation can achieve a throughput gain by orders of magnitude over a frame-by-frame adaptation.

Lactobacilli, the dominant species of microorganisms in the vaginal flora of healthy women, play important roles to prevent bacterial vaginosis and other sexually transmitted diseases. In this study, we carried out studies on stress adaptation prior to various stress treatment. We found that heat or salt adapted KLB46 showed higher cell viability than non adapted upon heat stress at $60^{\circ}C$ for 20 min. When chloramphenicol was added during the adaptation process, heat tolerance was abolished. This result suggested that de novo protein synthesis was essential during adaptation.

Purpose: The purpose of this study was to explore the relationships of family strain, perceived social support, family hardiness, and family adaptation and identify the family resiliency factors for the adaptation of families who have a child with congenital heart disease. Method: The sample consisted of 90 families who had a child diagnosed with congenital heart disease and completed surgical treatment. Data was collected from parents using a questionnaire. Results: Results from path analyses revealed that family strain had a direct effect on both perceived social support and family hardiness, and an indirect effect on family adaptation. Also, the findings revealed that perceived social support had a direct effect on both family hardiness and family adaptation, and family hardiness had a direct effect on family adaptation. Thus, these results indicated that perceived social support and family hardiness had a mediating effect on family strain. Conclusion: Findings provide the evidence for the theoretical and empirical significance of perceived social support and family hardiness as family resiliency factors for family adaptation. Clinical implications of these findings might be discussed in terms of family-centered nursing interventions for the families who have a child with congenital heart disease based on an understanding of family resiliency for adaptation.
