In order to deal with the classification problems of type-2 fuzzy training samples on generalized credibility space. Firstly the type-2 fuzzy training samples are reduced to ordinary fuzzy samples by the mean reduction method. Secondly the definition of strong fuzzy linear separable data for type-2 fuzzy samples on generalized credibility space is introduced. Further, by utilizing fuzzy chance-constrained programming and classic support vector machine, a support vector machine based on type-2 fuzzy training samples and established on generalized credibility space is given. An example shows the efficiency of the support vector machine.

In this study, we analyze the credit information (loan, delinquency information, etc.) of individual business owners to generate voluminous training data to establish a bankruptcy prediction model through a partial synthetic training technique. Furthermore, we evaluate the prediction performance of the newly generated data compared to the actual data. When using conditional tabular generative adversarial networks (CTGAN)-based training data generated by the experimental results (a logistic regression task), the recall is improved by 1.75 times compared to that obtained using the actual data. The probability that both the actual and generated data are sampled over an identical distribution is verified to be much higher than 80%. Providing artificial intelligence training data through data synthesis in the fields of credit rating and default risk prediction of individual businesses, which have not been relatively active in research, promotes further in-depth research efforts focused on utilizing such methods.

The domestic Radiation Technology is integrated into and utilized in various areas and is closely related to the industrial growth in Korea. The domestic use of radiation and RI (Radioisotope) increases in quantity every year, however the level of technology is poor when compared to other developed countries. Manpower training is essential for the development of Radiation Technology. Therefore, this study aimed to propose a methodology for designing systemic education and training model in the field of measurement and analysis of radiation. A survey was conducted to design education and training model and the training program for measurement and analysis of radiation was developed based on the survey results. The education and training program designed in this study will be utilized as a model for evaluating the professional development and effective recruitment of the professional workforce, and can be further applied to other radiation-related fields.

Objectives: The purpose of this study was to evaluate the effects of assertiveness training on assertiveness behavior, problem solving ability, and interpersonal relationships of nursing college students. Methods: A nonequivalent pre- and post-test experimental design was used. This study included 15 subjects in the experimental group, and 15 subjects in the control group, who were sophomore nursing students recruited from Gachon Nursing School located in Inchon City. The experimental group received 8 series of a ready planned and reorganized assertiveness training course, while the control group did not receive any training. The 120 minute training session was held on a weekly basis. The Maan-Whitney U Test was done to identify the changes in scores of assertiveness behavior, problem solving ability, and interpersonal relationships between the experimental and the control groups, after the assertiveness training. The data were collected before and after each part of the assertiveness training. The data collection period was from May 7 to July 10, 2001. Results: 1) The assertiveness behavior scores of the nursing students who participated in the assertiveness training were higher than those of the nursing students who did not participate in the assertiveness training. 2) The self problem solving evaluation scores of the nursing students who received assertiveness training were higher than those of the nursing students who did not receive the training. 3) The interpersonal relationship scores of the nursing students who participated in the assertiveness training were higher than those of the nursing students who did not participate in the assertiveness training. Conclusion: The study results showed that the assertiveness training was effective in promoting assertiveness behavior, problem solving ability, and changes in interpersonal relationships in nursing college students. It is suggested that well designed strategies are needed in the further studies in order to expand and apply the assertiveness training to other nursing student and nurse cohorts.

Objectives: This study aimed to evaluate the impact of a training course on pharmacovigilance for future doctors of Korean medicine (DKM). Methods: In 2020, a pharmacovigilance training course was conducted for 57 senior students of a Korean medicine (KM) college, and its impact to the students were assessed in terms of the knowledge, attitudes, and perceptions of these students at three-time points: pre-training, post-training, and 4-6 months after the end of the training. Results: A total of 38 students completed the survey. The average score from the knowledge test increased significantly after training compared to prior to the training (5.47±2.140, 6.61±1.001, respectively, p<0.001) and was maintained until the final survey (6.61±1.220). The rate of correct answers to most of the knowledge test questions increased after the training but decreased in the final survey. In terms of attitudes, self-confidence in causality assessment (2.63±1.025, 4.58±0.826, p<0.001) and spontaneous reporting (2.08±1.050, 4.74±0.446, p<0.001) significantly increased after the training and then slightly decreased (3.92±1.171, 4.40±0.755). The perception level was high prior to the training, and this pattern was maintained throughout the study period. Students responded that pharmacovigilance education was necessary for DKM after training, and for the undergraduates of KM colleges. Conclusions: This study shows that this pharmacovigilance training course is effective for students majoring in KM but that retraining is required at least 6 months after the initial training. Further follow-up studies are needed to ensure that students actively participate in spontaneous reporting after graduation, and continuous education should be provided to graduates.

Data is critical in deep learning but the scarcity of data often occurs in research, especially in the preparation of the paired training data. In this paper, document image binarization with unpaired data is studied by introducing adversarial learning, excluding the need for supervised or labeled datasets. However, the simple extension of the previous unpaired training to binarization inevitably leads to poor performance compared to paired data training. Thus, a new deep learning approach is proposed by introducing a multi-diversity of higher quality generated images. In this paper, a two-stage model is proposed that comprises the generative adversarial network (GAN) followed by the U-net network. In the first stage, the GAN uses the unpaired image data to create paired image data. With the second stage, the generated paired image data are passed through the U-net network for binarization. Thus, the trained U-net becomes the binarization model during the testing. The proposed model has been evaluated over the publicly available DIBCO dataset and it outperforms other techniques on unpaired training data. The paper shows the potential of using unpaired data for binarization, for the first time in the literature, which can be further improved to replace paired data training for binarization in the future.

PURPOSE: This study was aimed to investigate the effects of pelvic movements-based training on trunk stability and balance during sitting in children with spastic cerebral palsy. METHODS: Ten children with spastic cerebral palsy were matched to an intervention (n=5) or control group (n=5). The intervention consisted of two weeks of pelvic movements-based training, five times a week. All participants were evaluated before, during, and after pelvic movements-based training using a trunk impairment scale (TIS) for trunk stability and a modified functional reaching test for balance during sitting. The collected data were analyzed using Repeated Measures ANOVA and the Mann-Whitney U test. RESULTS: The results of this study were as follows: 1) Significant increases in the TIS score (only dynamic balance) and forward reaching were observed in the experimental group, compared with the control group, after training (P<.05). 2) There were statistically significant time-factor increases within and between the subject' effects, in the TIS score (dynamic balance and total), dominant side, non-dominant side, and forward reaching (P<.05). CONCLUSION: In conclusion, this study showed that for children with spastic cerebral palsy, pelvic movements-based training improves trunk stability and balance during sitting. Further studies will be required to determine the long-term effects of pelvic movements-based training.

Purpose: This study aimed to assess the effectiveness of gait training with the use of an electromechanical gait trainer with functional electrical stimulation (FES) for patients that had undergone subacute stroke. Methods: The study subjects included nine subacute stroke patients of the Korea National Rehabilitation Center in Seoul, Korea. Outcome was measured using the timed Up and Go test, Fugl-Meyer-L/E assesment, with determination of the comfortable maximal gait speed, composite spasticity score, functional ambulatory category and Berg balance scale. All measured scores were recorded before, during, and after rehabilitation and at an eight-week follow-up. Results: Patients who received electromechanical-assisted gait training in combination with FES after subacute stroke were more likely to achieve independent walking, functional activities, balance and gait speed. Conclusion: The outcome of our gait-training program demonstrates that it may be practical to integrate FES into electromechanical gait training without any adverse effects. However, further randomized controlled studies are needed to evaluate if patient outcome after combined training is superior to outcome after the use of electromechanical gait trainer treatment alone or conventional gait training alone.
