  • Deep learning models require high computing power due to a substantial amount of computation. It is difficult to use them in devices with limited computing environments, such as coastal surveillance equipments. In this study, a lightweight model is constructed by analyzing the weight changes of the convolutional layers during the training process based on MobileNet and then pruning the layers that affects the model less. The performance comparison results show that the lightweight model maintains performance while reducing computational load, parameters, model size, and data processing speed. As a result of this study, an effective pruning method for constructing lightweight deep learning models and the possibility of using equipment resources efficiently through lightweight models in limited computing environments such as coastal surveillance equipments are presented.

  • We introduce, in this paper, the face recognition method that improves recognition rate and training time in eigen system. To increase recognition rate we use Gabor filter. To reduce the increasing training time owing to use Gabor filtering, we extract new feature vectors that are made with average and standard deviation. In experimental results, we get higher recognition rate and shorter training time in improved system than it in original eigen system.

  • This paper deals with the construction of system for correct location determination of fixed tag. We adapted to construct the above method. Also we adapted the several filtering method. This system was constructed through using of several filtering methods to decrease the location determination error and fingerprint method which is composed of training phase and positioning phase. We constructed this system using Labview 2010 and MS-SQL 2000 as database. This system results in less location determination error than least square method, triangulation positioning method, and other fingerprint methods.

  • Purpose: The purpose of this study is to investigate and to verification of changes that the effect of treadmill and body weight support treadmill training on balance and gait ability for sub-acute stroke patients during 4 week. Method: 16 subjects who was diagnosed stroke were divided into 2 groups(8-treadmill training group, 8-body weight support treadmill group) by randomized control trial. Both training programs were consisted with 40 minuted, 5 times a week for 4 weeks and after training programs. Analysis: We analysed effects and changes on balance and gait ability. Analyses were performed using PASW ver. 18.0 and results were reported as mean ${\pm}$ standard deviation (S.D.). To investigate within group comparisons and to verification on effects of exercise, we did paired t test and repeated measured ANOVA test. Significance was set at p<.05. Result: Both training programs showed positive changes in Limit of Stability but significant results which is area of hemiside, area of intact side, area of posterior, total area were reported in body weight support treadmill training group. Changes of Berg Balance Scale was significantly increase and it had significant correlation between groups. Changes of 6 Minutes Walking Test was significant increase in both groups but there was no significant changes on Foot print and Romberg test. Conclusion: After considering all factors, both training programs showed effect on improvement of balance and gait ability in sub-acute stroke patients, but body weight support treadmill training group had better improvement in dynamic balance than treadmill training group. For the increase of balance and gait ability in sub-acute stroke patients, we need to continues study on difference of treadmill and body weight support treadmill and then we will give stroke patients a better satisfaction if we develop and provide a rehabilitation program for improvement of balance and gait ability.

  • PURPOSE: The purpose of this study was to examine the effects of dual-task training with cognitive tasks on cognitive functions and β-amyloid levels in the elderly with mild dementia. METHODS: The subjects were 36 elderly inpatients diagnosed with mild dementia at S Hospital located in Gyeongsangbuk-do, South Korea. The patients were randomly divided into a dual-task training group (DTG; n = 18) or a single-task training group (STG; n = 18). DTG performed dual-task training with cognitive tasks while STG performed only exercise tasks. These groups performed their respective exercises during a 30-minute session occurring three times a week over an 8-week period. MMSE-K and GDS were used to measure the subjects' cognitive function. To assess the subjects' dementia-related factors, their β-amyloid levels were measured by blood analysis. RESULTS: The results of the experiment were as follows: DTG showed statistically significant differences between their MMSE-K scores and β-amyloid levels before and after training (p < .05), whereas they exhibited no statistically significant differences in their GDS scores. MMSE-K scores and β-amyloid levels were significantly different between DTG and STG after training. CONCLUSION: The present study's overall results indicate that dual-task training with cognitive tasks is more effective than single-task training in improving cognitive functions and β-amyloid levels in the elderly with mild dementia. In other words, regular dual-task training can be considered as effective in improving cognitive function and dementia-related factors in the elderly with mild dementia and thus may be suggested as an effective exercise method for the treatment and early prevention of dementia.

  • This study used a qualitative research method to comprehensively deal with child care training in depth with the following content: the goals of child care teachers preparing for practical training; how they perform and feel about their roles throughout the training period as child care teachers; and their evaluation after the training period. A total of 10 people participated in the research and the training activities of child care teachers were qualitatively explored based on the results. The research findings are as follows. First, child care teachers have expectations for prospective teachers and take time for self-evaluation while preparing for teaching. Also, child care teachers set a goal of helping prospective teachers develop into outstanding teachers and have expectations for it. Second, child care teachers evaluate prospective teachers by treating them as colleagues while teaching them. Furthermore, child care teachers consider themselves as educators who train and produce child care professionals. Prospective teachers define their roles as assistants and learners in the actual educational scene. In addition, child care teachers feel a sense of pride by performing as hands-on training teachers. At the same time, they reflect on themselves by evaluating their duties as educators in their relationships with prospective teachers. Third, child care teachers suggested the need for changing the training system for themselves and prospective teachers after training. In addition, they argued that the gaps between school education and the actual educational scene should be reduced through solid training for acquiring new knowledge and information in both places in accordance with the rapidly-changing child care environment. Finally, the suggested the necessity of establishing a standard training curriculum and educational programs within their institution.

  • The propose of this study was to analyze the relationships among the levels of training & development evaluation (reaction, learning, transfer). The study has been conducted on 730 trainees who attended in the basic accounting program in L training and development institution through three incidents of tracked research such as reaction survey right after the conclusion of training, learning evaluation through test, and an evaluation of the transferability after 3 months of training. Questionnaires and test papers for analyses were used after their reliability, validity, difficulty, and discrimination have been verified on a pre-test. The research has been conducted for six months from 4 March 1996 to the end of August 1996, and data have been collected through direct research and survey through mail. The collected data have been worked on at SAS program for Windows with a statistical significance level of 5%. Statistical method that had been used was Pearson's correlation coefficient. The result and conclusion acquired from this study were as follows: Between reaction and learning, learning and transfer of training, only a weak positive correlation exists and explanation or prediction variance showing hierarchical relationship was quite weak with 1%. Thus, this research not only does not strongly support Kirkpatrick(1976)'s hierarchical model of $reaction{\rightarrow}learning{\rightarrow}transfer$, but also indicates that the separate measurement on each levels of training evaluation needs to be done. On the other hand, there was a relatively strong positive correlation between reaction and transfer of training. Based on the result, the conclusion, and the restriction perceived through this study, the following suggestions were made. 1. There is a need to empirically analyze and verify the hierarchy of all levels of training evaluation including the evaluation of the fourth level (result) such as organizational productivity, organizational satisfaction, and separation rate. 2. A great deal of efforts will be needed to systematically analyze what the relationships are among the methods measuring the level of evaluation of the training and development, and to apply this result to the training field.
