The goal of language model adaptation is to improve the background language model with a relatively small adaptation corpus. This study presents a language model adaptation technique where additional text data for the adaptation do not exist. We propose the information retrieval (IR) technique with N-gram language modeling to collect the adaptation corpus from baseline text data. We also propose to use a dynamic language model interpolation coefficient to combine the background language model and the adapted language model. The interpolation coefficient is estimated from the word hypotheses obtained by segmenting the input speech data reserved for held-out validation data. This allows the final adapted model to improve the performance of the background model consistently The proposed approach reduces the word error rate by $13.6\%$ relative to baseline 4-gram for two-hour broadcast news speech recognition.

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.

Purpose - This study aims to determine whether history education for Korean-Chinese living in Korea affects their understanding for Korean society. It also aims to determine Korean-Chinese compatriots to recognize the necessity for History education. Research design, data, and methodology - In this study, two parts were examined, which were the analysis on the influence of history education and the Korean-Chinese compatriots' adaptation to Korean society. In the case of data survey, Korean-Chinese compatriots were selected who are living in Korea. The survey was conducted using the samples of 200 questionnaires in total. Results - The results of the analysis shows that their residence adaptation in Korea has a positive impact on future nationality. Moreover, the residence adaptation in Korea has positive implications for their future nationality and their longer residence duration in Korea has an effect on their hope for living in Korea. Conclusions - The study showed the historical consciousness and related demographic characteristics of Korean compatriots living in Korea. It also showed that the longer their education duration for Korean history in China, the more difficult their adaptation would be. Therefore, the long term effects of adaptation depended on the emphasis of Korean history.

This study examines the influence of mentoring function on major adaptation of university students in a fashion related department and identifies the moderating role of self-efficacy and mentor competence on the effectiveness of a fashion mentoring function. Questionnaire data were gathered from 266 university students in a fashion related department with previous experience in a mentoring program. The results showed that the psychosocial function, sensitivity developmental function, and the fashion career developmental function had a positive impact on the department adaptation (adaptation for professor and adaptation for learning). In addition, there were moderating effects of self-efficacy on the influence of the fashion career developmental function on professor adaptation and the moderating effects of mentor competence on the influence of the sensitivity developmental function on professor adaptation. The results of this study provide various guidelines for professors or administrators of fashion related departments who are interested in mentoring systems.

Purpose: The purpose of this study was to investigate the factors affecting adaptation to school life of freshmen enrolled in nursing at a Junior College. Method: The data were collected from questionnaires filled out by 312 nursing students in two schools at J and I city from March 7-11, 2011. Data were analyzed using the SPSS/WIN18 program. Result: Self-esteem and adaptation to school life were higher than previous advanced research showed, self-efficacy was moderate and stress to school life was lower than other studies. School adaptation level was related to satisfaction of friendship, school life and the nursing program. The subjects who have chosen nursing by themselves and male students scored higher in their school adaptation. The greatest factors affecting adaptation to school life were satisfaction of school life and stress respectively. Conclusion: Inpre-admission, enough information about nursing school life through experience of previous students must be given. Then, a school adaptation program which incorporates counseling and mentoring should be provided for supporting understanding of school life.

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.

The IEEE 802.11 compliant stations can transmit at multiple transmission rates. Selection of an appropriate transmission rate plays a significant role in determining the overall efficiency of a communication system. The technique which determines the channel state information and accordingly selects an appropriate transmission rate is called rate-adaptation protocol. The IEEE 802.11 standard does not provide standard specification for implementing a rate-adaptation protocol for its multi-rate capable wireless stations. Due to the lack of standard specification, there is a myriad of rate-adaptation protocols, proposed by industry and various research institutes. This paper surveys the existing rate-adaptation schemes, discusses various features which contribute significantly in the process of rate-adaptation, the timing constraints on such schemes, and the performance gains in terms of throughput, delay and energy efficiency; which can be gained by the use of rate-adaptation. The paper also discusses the implication of rate-adaptation schemes on the performance of overall communication and identifies existing research challenges in the design of rate-adaptation schemes.
