This study focused on retraining programs for cuisiniers and drawing attention to the necessity of retraining and the new method of retraining for cuisiniers as a professional in a knowledge based society. Case study review and interviews followed by thorough review of related literatures were taken place to give suggestions and comments for the improvement of job performance enhance training for cuisiniers. Interviews were done with current participants and institutional trainers in March, 2008. Result from the interviews showed that retraining was really necessary. It was concluded that various retraining programs organized and developed by an association could be the solution. Methods of retraining can take formats of distance learning, classroom learning, and blended learning. However, working condition for most cuisiniers at present would allow them to squeeze some time off to attend higher education and most restaurant companies are not big enough to offer systematic job training on site or not stable enough to arrange replacement workers. It is therefore suggested to adopt a blended learning method and further study on this subject is highly recommended.

In this paper, we propose a stage-wise knowledge transfer method that uses block-wise retraining to transfer the useful knowledge of a pre-trained residual network (ResNet) in a teacher-student framework (TSF). First, multiple hint information transfer and block-wise supervised retraining of the information was alternatively performed between teacher and student ResNet models. Next, Softened output information-based knowledge transfer was additionally considered in the TSF. The results experimentally showed that the proposed method using multiple hint-based bottom-up knowledge transfer coupled with incremental block-wise retraining provided the improved student ResNet with higher accuracy than existing KD and hint-based knowledge transfer methods considered in this study.

PURPOSE: The purpose of this study was to examine the effects of breathing retraining on asymmetry of diaphragm thickness in stroke patients. METHODS: This study was nonequivalent control group pre-post test design. Subjects were assigned to two different groups(intervention group=10, control group=12). Intervention group conducted breathing retraining program for six-week. Diaphragm thickness was assessed by ultrasound in B-mode with a 7.5 MHz linea probe. The collected data analyzed by Wilcoxon signed rank test and Mann-Whitney U test. RESULTS: The intervention group significantly increased diaphragm thickness ratio on paretic side but the control group showed no significant difference in diaphragm thickness ratio. The control group significantly increased asymmetry of diaphragm thickness, but intervention group showed no significant difference in asymmetry of diaphragm thickness. CONCLUSION: This study showed that breathing retraining increased diaphragm thickness ratio in stroke patients and prevent the increase of asymmetry in diaphragm thickness with stroke patients.

터널 내 CCTV를 통한 딥러닝 객체인식 적용에 있어서 터널의 열악한 환경조건, 즉 낮은 조도 및 심한 원근현상으로 인해 오탐지가 대량 발생한다. 이 문제는 객체인식 성능에 기반한 영상유고시스템의 신뢰성 문제로 직결되므로 정탐지 향상과 더불어 오탐지의 저감 방안이 더욱 필요한 상황이다. 이에 본 논문은 딥러닝 객체인식 모델을 기반으로, 오탐지 데이터의 재학습을 통해 오탐지의 저감뿐만 아니라 정탐지 성능 향상도 함께 추구하는 오탐지 학습법을 제안한다. 본 논문의 오탐지 학습법은 객체인식 단계를 기반으로 진행되며, 학습용 데이터셋 초기학습 - 검증용 데이터셋 추론 - 오탐지 데이터 정정 및 데이터셋 구성 - 학습용 데이터셋에 추가 후 재학습으로 이어진다. 본 논문은 이에 대한 성능을 검증하기 위해 실험을 진행하였으며, 우선 선행 실험을 통해 본 실험에 적용할 딥러닝 객체인식 모델의 최적 하이퍼파라미터를 결정하였다. 그리고 본 실험에서는 학습영상 포맷을 결정하기 위한 실험, 반복적인 오탐지 데이터셋의 재학습을 통해 장기적인 성능향상을 확인하기 위한 실험을 순차적으로 진행하였다. 그 결과, 첫 번째 본 실험에서는 추론된 영상 내에서 객체를 제외한 배경을 제거시키는 경우보다 배경을 포함시키는 경우가 객체인식 성능에 유리한 것으로 나타났으며, 두 번째 본 실험에서는 재학습 차수별 독립적으로 오탐지 데이터를 재학습시키는 경우보다 차수마다 발생하는 오탐지 데이터를 누적시켜 재학습 시키는 경우가 지속적인 객체인식 성능 향상 측면에서 유리한 것으로 나타났다. 두 실험을 통해 결정된 방법으로 오탐지 데이터 재학습을 진행한 결과, 차량 객체 클래스는 1차 재학습 이후부터 AP값이 0.95 이상 우수한 추론 성능이 발현되었으며, 5차 재학습까지 초기 추론 대비 약 1.06배 추론성능이 향상되었다. 보행자 객체 클래스는 재학습이 진행됨에 따라 지속적으로 추론 성능이 향상되었으며, 18차 재학습까지 초기 추론대비 2.3배 이상 추론성능이 자가 향상될 수 있음을 보였다.

With the types and targets of cyber attacks expanding and with personal information leaks increasing, the quantitative demand for information security specialists has increased. The base for training the workforce has expanded accordingly, but joblessness and job-seeking still coexist. To resolve the gap between labor demand and supply, education and training systems that can supply demand quickly are needed. It takes a considerable amount of time for information security education and new manpower supply through universities and graduate schools to be reflected in the market. However, if information security retraining is carried out in terms of career development of information security and related workforce, the problem of lack of experts could be solved in a relatively short period. This paper investigates and analyzes the information security work of the information security workforce, the degree of skill level, the need for retraining, and the workplace migration experience; it also discusses the direction of career development retraining.

Objective: The purpose of this study was to confirm the validity of a respiratory retraining exercise using pressure biofeedback units among individuals with stroke as an effective intervention for improving quality of life. Design: Randomized controlled trial. Methods: Thirty patients with stroke were recruited as subjects. Among them, 15 patients were randomly assigned to an experimental group performing lumbar stabilization exercise and respiratory retraining exercise, and the other 15 patients were randomly assigned to a control group conducting only lumbar stabilization exercises. Exercises were conducted 3 times a week for 6 weeks, and quality of life was evaluated in the pre-test, 3 weeks and 6 weeks periods. The respiratory retraining exercises were performed using a pressure biofeedback unit and the degree of the quality of life was measured using the Stroke- Specific Quality of Life. For data analysis on the study results, a two-way repeated ANOVA was used in order to observe for changes in the measured variables according to time for both groups. If there was a reciprocal action between the groups and the time in the effect test within the entities, a one-way repeated ANOVA was implemented and was statistically processed. Results: There was a significant difference in the main effect test between the 2 populations depending on the duration of the experiment (6 weeks) (p<0.05). Conclusions: The above results showed that respiratory retraining exercises may provide positive effects in the treatment of stroke as the quality of life showed significant differences according to the duration of treatment.

Background : Treadmill training has been proposed as a useful adjunct to conventional physical therapy to restore ability to walk after stroke. The purpose of this study to inform clinical practise by evaluating the research evidence for the effectiveness of treadmill training after stroke. Methods : We searched to the effectiveness of any form of intervention for effect of treadmill training by Dankook University electronic library databases of Medline, Embase, Cinahl, Amed and PEDro combined with a hand search of papers published in relevant peer-reviewed journals. Any type of study relevant to the topic published in English during time period from 1980 to 2007 was included. Results : The literature search identified 35 studies. The included studies enrolled a total of 374 subjects. 1. Treadmill retraining without partial body weight support might be more effective than no treatment at improving gait velocity, get up and go time, gait endurance and step length symmetry. 2. Treadmill retraining with partial body weight support might be more effective than no treatment in improving step length symmetry, gait velocity, gait endurance and balance. 3. Treadmill retraining might be more effective with partial body weight support than without it at improving gait velocity and motor improvement as measured by The Stroke Rehabilitation Assessment of Movement(STREAM). 4. Treadmill retraining without partial body weight support may be no different from physiotherapy and increase gait velocity to conventional gait therapy. 5. Treadmill retraining with partial body weight support may be no different from physiotherapy for gait velocity, motor recovery and balance. Conclusion The review suggests that although treadmill training of gait, especially with partial body weight support, might Improve gait parameters and functional mobility, unless treadmill training is directed at Improving gait speed it might be no more effective than conventional physical therapy at improving gait parameters.
