  • Robotically assisted microsurgery or telemicrosurgery is a new technique using robotic telemanipulators. This allows for the addition of optical magnification (which defines conventional microsurgery) to robotic instrument arms to allow the microsurgeon to perform complex microsurgical procedures. There are several possible applications for this platform in various microsurgical disciplines. Since 2009, basic skills training courses have been organized by the Robotic Assisted Microsurgical and Endoscopic Society. These basic courses are performed on training models in five levels of increasing complexity. This paper reviews the current state of the art in robotically asisted microsurgical training.

  • The field of Artificial Intelligence (AI) is growing, and many firms are investing in expert system, one of AI's subfields. An expert system is defined as a computer program designed to replicate some aspect of the decision making of one or more experts and to be used by nonexperts. The kernel of an expert system is the knowledge base, which consists of the facts and rules that represent the expert's knowledge. Firms need expert systems for training employees to provide competitive advantage. This paper describes the model of an instructional expert training system which interfaces to external programs, such as an ASCII file, a work-sheet program, and a database program. A model for such an expert training system, and its prototype have been developed to demonstrate its functionality. A modular knowledge base has been developed and implemented in support of this study. The modularized knowledge base offers the user an easy and quick maintenance of facts and rules, which are frequently required to change in future.

  • The recent manufacturing industry in Japan has found it difficult to transfer skills from trained workers to inexperienced workers because the former ages and then retires. This is a particular problem for lathe process, as this operation requires explicit and tacit knowledge, and defining the skills clearly in a manual is difficult. This study aims to develop a training system for lathe operation by using a simulator; this includes formulas that help define the relationship between the speed of tool feed and cutting sound/shape of chips which were proposed in the preceding study. The developed training system is verified the effectiveness.

  • This paper is propose for some guidelines in making curriculum for the training of archivists for Koran records. This paper pays special attention to the revival of the culture of record-keeping tradition of our owns. Without it's revival, a blind introduction of archival sciences based on Western civilizations can be ended up another version of cultural and academic imperialism as such in the field of the record-management of Korean records. Rapidly growing information and computer technology of our owns must be incorporated in the making of archivist training programs. It proposes that the opening of archival science major as a department at the graduate school level is in the long run essential, yet that of an associate master degree program can be in real an alternative. A training of archivists is not just to produce of a technician but a crafts(wo)man who would be in the vanguard of the renaissance of the record-keeping culture in Korea.

  • Haze removal is an object of scientific desire due to its various practical applications. Existing algorithms are founded upon histogram equalization, contrast maximization, or the growing trend of applying machine learning in image processing. Since machine learning-based algorithms solve problems based on the data, they usually perform better than those based on traditional image processing/computer vision techniques. However, to achieve such a high performance, one of the requisites is a large and reliable training database, which seems to be unattainable owing to the complexity of real hazy and haze-free images acquisition. As a result, researchers are currently using the synthetic database, obtained by introducing the synthetic haze drawn from the standard uniform distribution into the clear images. In this paper, we propose the enhanced equidistribution, improving upon our previous study on equidistribution, and use it to make a new database for training machine learning-based haze removal algorithms. A large number of experiments verify the effectiveness of our proposed methodology.

  • 대용량의 코퍼스로 학습한 사전학습 언어모델이 다양한 자연어처리 태스크에서 성능 향상에 도움을 주는 것은 많은 연구를 통해 증명되었다. 하지만 자원이 부족한 언어 환경에서 사전학습 언어모델 학습을 위한 대용량의 코퍼스를 구축하는데는 한계가 있다. 이러한 한계를 극복할 수 있는 Cross-lingual Post-Training (XPT) 방법론을 사용하여 비교적 자원이 부족한 한국어에서 해당 방법론의 효율성을 분석한다. XPT 방법론은 자원이 풍부한 영어의 사전학습 언어모델의 파라미터를 필요에 따라 선택적으로 재활용하여 사용하며 두 언어 사이의 관계를 학습하기 위해 적응계층을 사용한다. 이를 통해 관계추출 태스크에서 적은 양의 목표 언어 데이터셋만으로도 원시언어의 사전학습 모델보다 우수한 성능을 보이는 것을 확인한다. 더불어, 국내외 학계와 기업에서 공개한 한국어 사전학습 언어모델 및 한국어 multilingual 사전학습 모델에 대한 조사를 통해 각 모델의 특징을 분석한다

  • 본 논문에서는 MIMO-OFDM 시스템에서 월쉬 부호화된 훈련신호를 이용하는 새로운 채널 추정 방식을 제안하였다. 월쉬 부호화된 훈련신호는 시간 영역에서 서로 직교하도록 설계된다. 이러한 직교성을 이용하여 월쉬 디코딩을 수행하면 시간 영역에서 원하는 훈련 신호를 분리할 수 있고 채널 추정이 가능하다. 컴퓨터 시뮬레이션 결과 제안된 방법은 계산량 감소에도 불구하고 최적 훈련 신호를 사용하는Li의 원래 방법[4]과 비교했을 때 거의 동일한 mean square error (MSE) 성능을 보였다.

  • In this paper, we propose a new training system for the improvement of equilibrium sense using unstable platform. The equilibrium sense, which provides orientation with respect to gravity, is important to integrate the vision, somatosensory and vestibular function to maintain the equilibrium sense of the human body. In order to improve the equilibrium sense, we developed the software program such as a block game, pingpong game using Visual C++. These training system for the equilibrium sense consists of unstable platform, computer interface and software program. The unstable platform was a simple structure of elliptical-type which included tilt sensor, wireless RF module and the device of power supply. To evaluate the effect of balance training, we measured and evaluated the parameters as the moving time to the target, duration to maintain cursor in the target of screen and the error between sine curve and acquired data. As a results, the moving time to the target and duration to maintain cursor in the target was improved through the repeating training of equilibrium sense. It was concluded that this system was reliable in the evaluation of equilibrium sense. This system might be applied to clinical use as an effective balance training system.

  • Purpose: This study examined whether 1) the motor inhibition response as cognitive-behavioral component is learning though a stop signal task using stop-signal paradigm, and 2) whether there is a difference in the learning degree according to imagery training and actual practice training. Methods: Twenty young adults (males: 9, females: 11) volunteered to participate in this study, and were divided randomly into motor imagery training (IT, n=10) and practice training (PT, n=10) groups. The PT group performed an actual practice stop-signal task, while the IT group performed imagery training, which showed a stop-signal task on a monitor of a personal computer. The non-signal reaction time and stop-signal reaction time of both groups were assessed during the stop-signal task. Results: In the non-signal reaction time, there were no significant intra-group and inter-group differences between pre- and post-intervention in both groups (p>0.05). The stop-signal reaction time showed a significant difference in the PT group in the intra-group analysis (p<0.05). On the other hand, there was no significant intra-group difference in the IT group and inter-group difference between pre- and post-intervention (p>0.05). Conclusion: These results showed that the motor inhibition response could be learned through a stop-signal task. Moreover, these findings suggest that actual practice is a more effective method for learning the motor inhibition response.
