For the acoustic models of embedded speech recognition systems, hidden Markov models (HMMs) are usually quantized and the original full space distributions are represented by combinations of a few quantized distribution prototypes. We propose a maximum likelihood objective function to train the quantized distribution prototypes. The experimental results show that the new training algorithm and the link structure adaptation scheme for the quantized HMMs reduce the word recognition error rate by 20.0%.

유선을 통한 전술훈련시스템은 개활지 및 야지에서 실질적인 전장 상황 묘사에 따른 훈련성과를 기대하기 어렵다. 따라서, 본 논문에서는 국내 외 적용된 사례가 없는 USN(Ubiquitous Sensor Network) WMN(Wireless Mesh Network)을 활용한 전술훈련 및 훈련평가 시스템을 구축하여 보다 높은 훈련성과를 증대시키고, 원격제어를 통한 전술훈련 모니터링시스템을 구현하여 감지데이터를 통한 훈련장비의 상태 및 자동화된 훈련결과 출력 및 관리자의 편이성을 보장하고자 한다. 현재 사용되고 있는 전술훈련시스템의 문제점을 개선하고, USN을 이용하여 센서에 의해 수집된 훈련정보를 전송하고 처리하기 위해 서버와 연동을 제어하는 컨트롤러 및 GUI방식의 시스템을 개발했다. 이 시스템은 하드웨어의 다양한 기능을 처리하기 위해 기존 프로토콜의 개선과 신규 프로토콜의 적용이 수월하며, 통제시스템의 제어의도에 따라 발생할 수 있는 다양한 상황대처에 대한 알고리즘을 쉽게 적용 및 수정 할 수 있다.

Objectives: The purpose of this study was to recognize the importance of dental hygienist's communication competence and to establish the basis for developing a program to improve communication competence. Methods: A survey was conducted on members who underwent participatory training in some trials in 2019, and a total of 348 people were analyzed. Results: Total communication competence was 3.63 points. The highest area was 3.88 points for understanding others' standards, and the lowest area was 3.27 points for escaping stereotypes. Most areas of communication showed statistically significant positive correlations, but in some areas, there was an inverse correlation. As a dental hygienist, it is necessary to provide systematic education for improving communication competence from college students. Conclusions: In addition, it is necessary to develop and implement a training program for improving communication competence of dental hygienists.

Background: This paper presents the findings of a pilot research survey which assessed the degree of balance between safety and productivity, and its relationship with awareness and communication of human factors and safety rules in the aircraft manufacturing environment. Methods: The study was carried out at two Australian aircraft manufacturing facilities where a Likert-scale questionnaire was administered to a representative sample. The research instrument included topics relevant to the safety and human factors training provided to the target workforce. The answers were processed in overall, and against demographic characteristics of the sample population. Results: The workers were sufficiently aware of how human factors and safety rules influence their performance and acknowledged that supervisors had adequately communicated such topics. Safety and productivity seemed equally balanced across the sample. A preference for the former over the latter was associated with a higher awareness about human factors and safety rules, but not linked with safety communication. The size of the facility and the length and type of employment were occasionally correlated with responses to some communication and human factors topics and the equilibrium between productivity and safety. Conclusion: Although human factors training had been provided and sufficient bidirectional communication was present across the sample, it seems that quality and complexity factors might have influenced the effects of those safety related practices on the safety-productivity balance for specific parts of the population studied. Customization of safety training and communication to specific characteristics of employees may be necessary to achieve the desired outcomes.

A study on the global trend of accreditation for mediators implies many important aspects of controlling of the quality of mediation. Firstly, whether or not having an accreditation system, most European countries and the U.S. have a common understanding on the fact that mediators need to be trained to mediate disputes, apart from their own expertise on the subject matters. Secondly, private-led accreditation has been utilized in countries having a Anglo-American law system such as the United Kingdom and the U.S. a while nation-managed one has been operated in the countries having a continental law system such as Austria, Belgium, Italy and Germany. Thirdly, private mediation service providers (usually institutions or companies) play an active role in the training and accreditation of mediators and further make them act as mediators in the disputes referred to them. Fourthly, the countries having a nation-managed accreditation system usually stipulate a certain mediation training and accreditation requirement by law. Fifthly, there is no uniform trend on the minimum hours of training required for accrediting the mediators. Sixthly, mediation training generally focuses on the practical mediation capacity-building, including mediation theory and role-playing, mediation simulations, peer review and supervision. And finally, the mediation theory mainly includes the role of mediator, mediation procedures, mediation communication, negotiation and communication skills, mediation ethics and mediator's code of conduct, etc.

IT 관련 교과에서 실습 교육이 그 어느 때보다 강조되고 있다. 이 글은 IT 교육을 위한 클라우드 컴퓨팅 기반의 가상 데스크탑 서비스 제공 방안과 효율적인 운영 관리 방안을 연구하였다. 구현된 가상 실습 환경 시스템을 이용하면 교과의 커리큘럼에 적합하도록 커스토마이징된 실습환경을 제공할 수 있다. 뿐만 아니라, 제안된 시스템을 이용할 경우 교과운영 사전에 미리 교과별로 프로비저닝 할 수 있다. 따라서 본 논문에서 산정한 규모와 운영 정책을 참고하여 여러 사이버대학이 공동 활용할 수 있는 클라우드 실습 포털시스템을 구축한다면 보다 효율적이고 효과적인 가상실습 교육 서비스 시스템을 구축하고 제공할 수 있을 것으로 예상된다.

Unsupervised neural networks have not caught enough attention until Generative Adversarial Network (GAN) was proposed. By using both the generator and discriminator networks, GAN can extract the main characteristic of the original dataset and produce new data with similarlatent statistics. However, researchers understand fully that training GAN is not easy because of its unstable condition. The discriminator usually performs too good when helping the generator to learn statistics of the training datasets. Thus, the generated data is not compelling. Various research have focused on how to improve the stability and classification accuracy of GAN. However, few studies delve into how to improve the training efficiency and to save training time. In this paper, we propose a novel optimizer, named FAST-ADAM, which integrates the Lookahead to ADAM optimizer to train the generator of a semi-supervised generative adversarial network (SSGAN). We experiment to assess the feasibility and performance of our optimizer using Canadian Institute For Advanced Research - 10 (CIFAR-10) benchmark dataset. From the experiment results, we show that FAST-ADAM can help the generator to reach convergence faster than the original ADAM while maintaining comparable training accuracy results.

The purpose of this study was to investigate the pre- and post-exercise performance, edema, and pain of plyometrics in water and land environments. Twelve males in their 20s were selected as subjects and performed 10 sets of squat jumps 10 times in 2 environmental conditions (water and ground). There was no significant difference in iEMG of vastus medilais according to exercise conditions and time. In MPV of CMJ, there was no significant difference according to exercise conditions and time. The thigh circumference showed a significant difference according to the exercise condition and time, and was higher in the ground condition after exercise. There was a significant difference in pain according to the exercise condition and time, and it was found to be high after exercise, 48 hours, and 72 hours in the ground condition. We believe that plyometric training in an aquatic environment will have less swelling and pain compared to plyometric training conducted in a land environment, and the pain will improve quickly, so we think that training can be conducted in a relatively shorter period than in the land environment.
