Teachers' beliefs about teaching English are reflected in their practices in the classroom. They influence on the students' attitude to English learning. Any teacher training program expects the trainees to change or modify their existing beliefs and attitude through the new ideas and information introduced by the program toward a desired direction. The present study describes a teacher training program for elementary school English teachers and compares the beliefs of the teachers about teaching English before and after the training. The subjects are the elementary school English teachers around Chungnam area who get a special training of 120 hours during January 1997. The investigation of the subjects' beliefs on English teaching is conducted through examining two journals of each subject before and after the training. The journals show the teachers' inner flow of thought, so teacher trainers are expected to get insight on their general instructional considerations and have implications on the future teacher training program through examining these journals. In addition, the journal writing itself gives the teachers opportunity to reflect their practice and rethink about their beliefs, and develop themselves as professional English teachers.

In this paper, we describe self-training super-resolution. Our approach is based on example based algorithms. Example based algorithms need training images, and selection of those changes the result of the algorithm. Consequently it is important to choose training images. We propose self-training based super-resolution algorithm which use an input image itself as a training image. It seems like other example based super-resolution methods, but we consider training phase as the step to collect primitive information of the input image. And some artifacts along the edge are visible in applying example based algorithms. We reduce those artifacts giving weights in consideration of the edge direction. We demonstrate the performance of our approach is reasonable several synthetic images and real images.

As the size of data and models in machine learning training continues to grow, training on a single server is becoming increasingly challenging. Consequently, the importance of distributed machine learning, which distributes computational loads across multiple machines, is becoming more prominent. However, several unresolved issues remain regarding the performance enhancement of distributed machine learning, including communication overhead, inter-node synchronization challenges, data imbalance and bias, as well as resource management and scheduling. In this paper, we propose ParamHub, which utilizes orchestration to accelerate training speed. This system monitors the performance of each node after the first iteration and reallocates resources to slow nodes, thereby speeding up the training process. This approach ensures that resources are appropriately allocated to nodes in need, maximizing the overall efficiency of resource utilization and enabling all nodes to perform tasks uniformly, resulting in a faster training speed overall. Furthermore, this method enhances the system's scalability and flexibility, allowing for effective application in clusters of various sizes.

본 연구에서는 최근 일본의 교원연수에서 중요한 '학교조직 매니지먼트' 연수의 운영방법에 대해 조사하였다. 학교조직매니지먼트 연수는 변화하고 있는 사회에 대하여 유연하게 대응할 수 있는 교원의 자질과 능력을 개발하기 위해 필수적인 연수의 체계이다. 기존의 학교장과 같은 관리직만의 문제라고 생각되었던 학교경영의 문제가 팀으로서의 학교를 지향하는 가운데 교직원 공동의 과제로 인식되고 있으며 이는 학교경영에 대한 인식의 본질적인 전환이다. 이 같은 변화는 학교 경영이 더이상 학교장만의 전유물이 아니며 학교 조직의 모든 구성원 나아가 지역사회의 구성원까지도 그 책임을 나누어 가져야 한다는 인식으로부터 시작되었다.. '지역과 연계한 학교', '정보가 열린 공개형의 학교' '교육과정과 새로운 수업의 방식에 대해 항상 생각하는 학교' 등 현재의 교육에 관한 문제에 대하여 해결하는 '학교조직매니지먼트' 연수는 이 같은 문제의 대안으로서 강조되고 있다. 지금은 복잡해지고 다양해지는 현 사회와 교육 환경에 적응하기 위한 교육과정의 개발 개혁과 함께 학교 조직의 변화를 생각하지 않으면 안 될 때이다. 그런 의미에서 새로운 기업가형의 학교조직 매니지먼트 연수는 이 시대의 요구에 적절히 부응할 수 있는 체제라고 할 수 있을 것이다.

This study describes design and development techniques of estimation models for process modeling. One case study is undertaken to design a model using standard gas furnace data. Neural networks (NN) and genetic programming (GP) are each employed to model the crucial relationships between input factors and output responses. In the case study, two models were generated by using 70% training data and evaluated by using 30% testing data for genetic programming and neural network modeling. The model performance was compared by using RMSE values, which were calculated based on the model outputs. The average RMSE for training and testing were 0.8925 (training) and 0.9951 (testing) for the NN model, and 0.707227 (training) and 0.673150 (testing) for the GP model, respectively. As concern the results, the NN model has a strong advantage in model training (using the all data for training), and the GP model appears to have an advantage in model testing (using the separated data for training and testing). The performance reproducibility of the GP model is good, so this approach appears suitable for modeling physical fabrication processes.

Purpose : This article was a quasi-experimental study that applies to external -feedback weight-bearing training among hemiplegic patients with a stoke. Methods : It examined whether position sense and balance can improve fall efficacy and prevent a fall. The subject of study was divided in two; Experimental group had 18 people and control group had 16 people. It took 8 weeks to finish training. Experimental group provides external-feedback weight-bearing training for ten minutes after neurological treatment for 20 minutes and control group provides nerves treatment for 30 minutes. To find the effect of a fall assessed position sense, balance and fall efficacy of the lower limbs before the fact, after 4 weeks and 8 weeks. Results : According to the conclusions, external-feedback weight-bearing training to prevent a fall was more effective intervention in experimental group than in control group. Conclusion : This study suggests that external-feedback weight-bearing training is a intervention to prevent the fall of hemiplegic patients with a stroke effectively.

Background: The high sensitivity of individuals toward safety information in production activities, that is, attentional bias toward safety (ABS), can positively predict safe behaviors. It has become a hot topic in current organizational safety behavior research. However, there is no literature on its modification method. Methods: Based on the modified dot-probe task, we designed a modification training method of ABS. The training method required subjects to respond to the location of detection points that presented after safety stimulus and neutral stimulus pictures. Subjects' attentional bias values of safety and neutral pictures were measured during the experiment. Twenty-one students were selected and divided into a control group and training group to gain comparable results. Results: A novel training method was developed in this study to promote the efficacy of safety stimulus by activating ABS of the subjects. Moreover, repeated trainings and preacquired relative knowledge can enhance this effect. Conclusion: This study develops an experimental approach to evaluate the effectiveness of safety education and safety training, and also provides a new research idea for accident prevention.

Background: Recently, the use of ultrasound (US) techniques in regional anesthesia and pain medicine has increased significantly. However, the current extent of training in the use of US-guided pain management procedures in Korea remains unknown. The purpose of the present study was to assess the current state of US training provided during Korean Pain Society (KPS) pain fellowship programs through the comparative analysis between training hospitals. Methods: We conducted an anonymous survey of 51 pain physicians who had completed KPS fellowships in 2017. Items pertained to current US practices and education, as well as the types of techniques and amount of experience with US-guided pain management procedures. Responses were compared based on the tier of the training hospital. Results: Among the 51 respondents, 14 received training at first- and second-tier hospitals (Group A), while 37 received training at third-tier hospitals (Group B). The mean total duration of pain training during the 1-year fellowship was 7.4 months in Group A and 8.4 months in Group B. Our analysis revealed that 36% and 40% of respondents in Groups A and B received dedicated US training, respectively. Most respondents underwent US training in patient-care settings under the supervision of attending physicians. Cervical root, stellate ganglion, piriformis, and lumbar plexus blocks were more commonly performed by Group B than by Group A (P < 0.05). Conclusions: Instruction regarding US-guided pain management interventions varied among fellowship training hospitals, highlighting the need for the development of educational standards that mandate a minimum number of US-guided nerve blocks or injections during fellowships in interventional pain management.

Purpose: This study examined the effects of computerized feedback postural training on the balance and electromyography activity of subjects with stroke. Methods: A total of 30 chronic stroke patients were enrolled in this study. Subjects were divided into an experimental group (n=15) and a control group (n=15). Computerized feedback postural training was used in the experimental group. Both groups received intervention for six weeks, 5 times per 30 minutes period. Data analysis was performed using analysis of covariance for determination of statistical significance. Results: Significant difference in static and dynamic balance was observed in the experimental group, compared with the control group (p=0.05), and a significant difference in muscle activity was observed in the gastrocnemius muscle, quadriceps muscle, and elector spinae muscle. However, the hamstring muscle showed no significant difference. Conclusion: Computerized feedback postural training is more effective in improving the ability of balance and muscle activity than neurological physical therapy.

The purpose of this study was to assess the sanitary education performance for employee through school foodservice dietitians in Jeonju area. Questionaires were distributed to 67 dietitians of school foodservice. The statistical analysis of data was completed using SPSS 10.0 program. The results were summarized as follows: 47.8% of dietitians were $31{\sim}35$ years old and 73.1% were regular employee. 37.3% had a dietitian career less $5{\sim}10$ years old. Most dietitians(74.6%) provided verbal training to the school foodservice employees at least once every month. This training included details of personal, facility and food processing hygiene, food poisoning and microorganism. Because of 'missing time' had 65.7% of dietitian a problem to conduct the sanitary training. The working experience and academic background of dietitians influenced on the item of sanitary training, not on the frequency of training.
