Maximum likelihood linear regression (MLLR) adaptation experiences severe performance degradation with very tiny amount of adaptation data. Eigenspace- based MLLR, as an alternative to MLLR for fast speaker adaptation, also has a weak point that it cannot deal with the mismatch between training and testing environments. In this paper, we propose a simultaneous fast speaker and environment adaptation based on eigenspace-based MLLR. We also extend the sub-stream based eigenspace-based MLLR to generalize the eigenspace-based MLLR with bias compensation. A vocabulary-independent word recognition experiment shows the proposed algorithm is superior to eigenspace-based MLLR regardless of the amount of adaptation data in diverse noisy environments. Especially, proposed sub-stream eigenspace-based MLLR with bias compensation yields 67% relative improvement with 10 adaptation words in 10 dB SNR environment, in comparison with the conventional eigenspace-based MLLR.

This paper explores new techniques that are based on a hidden-layer linear transformation for fast speaker adaptation used in deep neural networks (DNNs). Conventional methods using affine transformations are ineffective because they require a relatively large number of parameters to perform. Meanwhile, methods that employ singular-value decomposition (SVD) are utilized because they are effective at reducing adaptive parameters. However, a matrix decomposition is computationally expensive when using online services. We propose the use of an extended diagonal linear transformation method to minimize adaptation parameters without SVD to increase the performance level for tasks that require smaller degrees of adaptation. In Korean large vocabulary continuous speech recognition (LVCSR) tasks, the proposed method shows significant improvements with error-reduction rates of 8.4% and 17.1% in five and 50 conversational sentence adaptations, respectively. Compared with the adaptation methods using SVD, there is an increased recognition performance with fewer parameters.

Introduction: This study aimed to investigate the adaptation to college life of dental hygiene students. Methods: A total of 300 students in the 3-year course, and 200 students in the 4-year course at the Department of Dental Hygiene, were selected. A self-reported questionnaire was used between 27th June and 31st August 2017. From this, 439 questionnaires were collected and analyzed. Results: 1. The overall degree of adaptation to college life, according to varied general characteristics of the subject students, appeared to show that male students had a higher degree of adaptation than female students. It also appeared to be higher in students that had a higher level of academic accomplishment(<0.001). 2. The average score of the degree of adaptation to college life was 2.57 points(full score of 4.00 points). Social adaption had the highest score of 2.92 points, while academic adaptation had the lowest score of 2.37 points. Regarding the subordinate domains of adaptation to college life, the average score of attachment adaptation of students in the 3-year course of the Department of Dental Hygiene(2.69 points) appeared to be higher than that of students in the 4-year course(2.52 points). The difference between these scores was statistically significant(p=0.001). 3. The effects of varied academic systems upon the degree of adaptation to college life were also analyzed. Emotional and attachment adaptation to college, as well as the academic accomplishment of students in the 3-year course, was distributed over a range of 3.0~3.5. This was significantly different compared to students in the 4-year course(p<0.05). Conclusion: It is necessary to develop stepwise and continuous educational programs to enable better college life adaptation for students in the Department of Dental Hygiene.

Eigenvoice 방법은 고속화자적응에 적합하다고 알려져 있지만, 이 방법은 발화수가 증가하더라도 추가적인 인식성능향상이 이루어지지 않는 단점이 있다. 본 논문에서는 이 문제를 해결하기 위해 음성 특징벡터의 차원별로 eigenvoice의 가중치를 구하여 적응시키는 방법과 또한 적응 데이터 수에 따라 높은 인식률을 얻는 적응 방식을 선택하는 방식을 제안한다. 화자독립모델 및 eigenvoice들을 구성하기 위해 POW (Phonetically Optimized Words)데이터베이스를 사용하였으며, PBW(Phonetically Balanced Words) 452단어 중50개까지 발화 수를 변화시키면서 교사방식 (Supervised mode)로 적응에 사용하고 나머지 중 400개를 인식실험에 사용하였다. 차원별 eigenvoice 방법이 발화수가 증가함에 따라 기존의 eigenvoice 나 MLLR 방법보다 높은 성능을 보였으며, eigenvoice와 차원별 eigenvoice방법 사이의 적응 모드 선택을 통해 기존의 eigenvoice 방식에 비해 최고 26%의 단어 오인식률 감소를 얻었다.

The subjects of this study consisted of 354 children. They were 6th grade of elementary school in Taegu city. The periods of study was from march 10, to march 18, 2000. Data were analyzed by SAS computer programme. The results of this study were as follows: 1. The mean score for stressor was 39.91 in children(range 24-72). The higher stressor among three subgroups of stressor was mass media stressor. The degree of stressor revealed to be influenced significantly economic status. 2. The most frequently used coping style was problem-oriented coping style(M=18.94) in children. The degree of emotion-oriented coping style revealed to be influenced significantly family's atmosphere 3. The mean score for communication with mother was 72,44 in children(range 20- 100). The degree of communication with mother revealed to be influenced significantly sex, economic status, family' atmosphere. 4. The mean score for school adaptation was 62.48 in children(range 25-100). The higher school adaptation among five subgroup was rule dimension. The degree of school adaptation revealed to be influenced significantly sex, birth, mother's job, economic status, family's atmosphere. 5. School adaptation were positively correlated with communication with mother, problem- oriented coping style(r=0.40 p<0.001) (r=0.30 p<0.001). 6. School adaptation were negatively correlated with emotion-oriented coping style, stressor (r=-0.16 p<0.01)(r=-0.13 p<0.01). 7. Forward multiple regression analysis revealed that the most powerful predictor was the variable communication with mother accounted for 15.25% in school adaptation. All variables accounted for 25.55% in school adaptation.

This study investigates the effect of recovery elasticity of beauty college students on university life adaptation during COVID-19. Further, the mediating effect of grit in relation to recovery elasticity and university life adaptation is analyzed. Survey data of 223 students (female: 192; male: 31) were collected for multiple and intermediate regression analyses using SPSS 24.0. The results reveal a static correlation between the lower factors of resilience, glittery, and adaptation to college life and that the resilience of junior college students in the beauty department had a static effect on grit and their adaptation to college life. Passion, a subordinate factor of grit, is mediated by the effect of grit on the relationship between resilience and adaptation to university life. However, perseverance, another subordinate factor of grit, did not have any such mediating effect. These results confirm the importance of grit, particularly passion, for resilience and adaptation to college life. It was confirmed that resilience was due to college life adaptation of beauty department students, and it was confirmed that passion, a sub-factor of grit, also had a mediating effect. Therefore, it is judged that resilience induces physical and mental adaptation, interpersonal adaptation, and academic adaptation necessary for college life, and works in many ways to improve the quality of life of beauty department junior college students. Instructors should consider developing educational programs for improving recovery elasticity and grit to help students better adapt to university life.

Purpose: This study was undertaken to obtain the basic data on the spouses‘ stress and adaptation caring their wives affected by gynecological cancer. In addition, moderating variables for adaptation, family resource and situational definition, were also investigated. Method: This study was descriptive survey research work by questionnaire on the 71 spouses hospitalized in an university hospital located on Gwangju from Sep. 2001 to Oct. 2002. Results: The mean score of stress was 2.27, and the mean score of adaptation was 3.12. The correlation between stress and adaptation was significant (r = -.692, p = .000). The adaptation score of high stress group with high family resource was higher (p = .041) than the group with low family resource. The adaptation score of high stress group with high situational definition was higher (p = .033) than the group with low situational definition. Conclusion: This study showed that the spouses experienced a similar level of stress compared with the level of families with other type of cancer. This study also showed that the stress and adaptation levels were different depending upon the family resource and situational definition. This aspect should be considered for the development of nursing intervention program for the spouse of patients with gynecological cancer.

Purpose: On the basis of the theoretical framework of a combination of Roy's adaptation theory and Lazarus & Folkman's theory of stress - appraise coping, the purpose of this study was to predict effect factors of adaptation to university life of Chinese international students in Korea. After this, a model of adaptation to university life of Chinese international students in Korea was constructed. Methods: A questionnaire was used to survey 369 Chinese international students from one university in Korea, which was analyzed by using PASW Statistics 18.0 and LISREL 8.7. Results: This theoretical model explained adaptation to university life of Chinese international students at 75.0% in Korea. Physical symptoms, loneliness, acculturation stress and self-efficacy directly affected the adaptation to university life. Korean language proficiency indirectly affected adaptation to university life through self-efficacy. Conclusion: Results of this study provided theoretical basis for the future health care of university- centered health centers. For improving adaptation to university life of Chinese international students in Korea, education and nursing measures for reducing physical symptoms, loneliness and acculturation stress, and improving Korean language proficiency and self-efficacy are proposed for further research and development.
