  • Purpose: Curricula for surgical residents should include training in trauma care; however, such training is absent in many low income countries. At the largest surgical training institution in Ethiopia, a trauma training program was developed, integrated into the existing surgical curriculum, and implemented. This study was conducted to evaluate the trainees' response to the new program. Methods: Over a 5-month period, 35 first-year surgical residents participated in weekly trauma care training sessions. The program included journal clubs, practical sessions, didactic sessions, and case-based discussions. Six months after the conclusion of the training, changes in knowledge, attitude, and practices were evaluated through a self-report survey. Results: For knowledge-based items, the survey data revealed reported improvements in 83.8% to 96.8% of students. Furthermore, 90.3% to 93.5% of participants indicated improvements in practice, while 96.7% exhibited a change in attitude. Respondents reported that attending didactic courses improved their presentation skills and facilitated the acquisition of knowledge. They suggested the inclusion of additional practical sessions. Conclusions: Training structures that are simple to implement are crucial for residency programs with limited resources. Such programs can be developed using existing academic staff and can aid residents in delivering improved care to trauma patients.

  • Radiation and its various industrial applications have been growing at approximately 10 percent per year for the past decade in Korea. As a result, the importance of the Education and Training (E&T) in radiation protection is of upmost importance. This paper is intended to investigate the present status of the E&T on radiation protection and safety in Korea and to draw up the improvements of the E&T courses required for building the national radiation safety infrastructure. For these purposes, the E&T data from the six major domestic organizations providing radiation protection training courses were investigated and analyzed. Each of the organizations is offering several kinds of E&T courses based on their own specific functions. These organizations have administrative facilities equipped with the latest technology for E&T in radiation protection. The E&T courses mainly cover the training courses for radiation workers, radiological emergency staff, license applicants, license holders, and regulatory staff. In 2010, a total of 58 E&T courses were carried out across six organizations. The conclusions make a number of observations highlighting challenges such as: establishing a formal feedback mechanism, introducing more practical training sessions, developing training courses tailored to the job categories and target audiences, and designing education and training courses in radiation protection that comply with current obligations as well as future requirements.

  • The purpose of this study is to examine the present operation process and to suggest the points of improvement so that vocational education and training institutions can be activated more effectively. The subjects of this study were 250 college students who completed or attended the vocational education and training course in Seoul and Gyeonggi-do, and collected 230 data, excluding inappropriate responses. Data analysis was performed by using the statistical package program SPSS Statistics (Ver. 24: IBM, USA). In this study, frequency analysis was conducted to examine the characteristics of data, and crossover analysis was conducted mainly to investigate the correlation between categorical data. The results of this study are as follows: First, it provides information about vocational education and training course to all general high school students at the beginning of the first year of high school, and then, from the first semester of the second grade, do. Second, it is to open four major courses in beauty education at the same time. This makes it possible to acquire qualifications according to four beauty courses during the training period at the training institute rather than the private education institute where private education expenses are incurred. By training all major courses in skin, hair, make-up, and nail art, you will be given the opportunity to carefully determine the major course that fits your aptitude. Based on the results of this research, we propose a plan to improve the vocational education system for vocational high school students who are majoring in cosmetology.

  • The physics-informed neural network (PINN) has been proposed to overcome the limitations of various numerical methods used to solve partial differential equations (PDEs) and the drawbacks of purely data-driven machine learning. The PINN directly applies PDEs to the construction of the loss function, introducing physical constraints to machine learning training. This technique can also be applied to wave equation modeling. However, to solve the wave equation using the PINN, second-order differentiations with respect to input data must be performed during neural network training, and the resulting wavefields contain complex dynamical phenomena, requiring careful strategies. This tutorial elucidates the fundamental concepts of the PINN and discusses considerations for wave equation modeling using the PINN approach. These considerations include spatial coordinate normalization, the selection of activation functions, and strategies for incorporating physics loss. Our experimental results demonstrated that normalizing the spatial coordinates of the training data leads to a more accurate reflection of initial conditions in neural network training for wave equation modeling. Furthermore, the characteristics of various functions were compared to select an appropriate activation function for wavefield prediction using neural networks. These comparisons focused on their differentiation with respect to input data and their convergence properties. Finally, the results of two scenarios for incorporating physics loss into the loss function during neural network training were compared. Through numerical experiments, a curriculum-based learning strategy, applying physics loss after the initial training steps, was more effective than utilizing physics loss from the early training steps. In addition, the effectiveness of the PINN technique was confirmed by comparing these results with those of training without any use of physics loss.

  • The purpose of this study was to examine the effects of Task-oriented training on the balance, lapse time and MVC(Maximum Voluntary Contraction) of CVA(cerebral vascular accident) patients. The active balance equipment was used to measure of the static balance, lapse time and task-oriented training. The EMG technique was used to record muscle activitie of affected side of gluteus medius and vastus medialis. The raw EMG data were filtered with band pass filter (60Hz) to remove artifacts and then low pass filtered (20Hz) to find the linear envelope which resemble muscle tension curve. The experiment had been conducted at the department of physical therapy in J hospital in M city during 8weeks. The thirty patients experienced the stroke were participated: training group (15), control group (15). They were ambulatory with or without an assistive device. They were assessed on central perturbation(mm) in the static balance, lapse time(s) and MVC test(mV). The data were analyzed using repeated measured ANOVA. The results were as follows: After Task-oriented training, central perturbation and lapse time was significantly differences in both groups(p<.001), and MVC in gluteus medius were no significant differences in both groups, but vastus medialis was significant differences in both groups (p<.001).

  • The lack of appropriate performance appraisal and evaluation of incubatees of technology incubation programmes in relation to entrepreneurship development in Nigeria is a major gap that needs to be bridged. This study examined the effect of selected technology incubation programme variables such as training, financing and marketing on entrepreneurship development in Nigeria. A closed-ended questionnaire was used for data collection from the quota-sampled population of the six (6) geo-political zones of Nigeria. Descriptive statistics were used to analyse the data while multiple regression was used to test the hypotheses. The results revealed that technology incubation training has a significant effect on entrepreneurial ability in Nigeria; there is a significant and positive effect of technology incubation financing on entrepreneurial funding portfolio; there is no significant impact of technology incubation marketing programme on entrepreneurial turnover; and technology incubation has no significant impact on entrepreneurial propensity. The study recommended that the National Board for Technology Incubation (NBTI) expand the training modules to capture pre, post and virtual incubatees; to facilitate access to risk funds, cheap capital and encourage establishment of venture capital; to improve on its marketing programme to encompass all marketing needs of incubatees beyond trade-fair participation. However, trade-fairs participation has a significant but limited effect on entrepreneurial turnover, while a technology incubation programme has no significant impact on entrepreneurial propensity, as only six (6) out of the twenty-nine (29) respondents started new venture from the incubation centers which are industrial training students and staff of the incubatees.

  • Existing LDA uses the transform matrix that maximizes distance between classes. So we have to convert from an image to one-dimensional vector as training vector. However, in 2D-LDA, we can directly use two-dimensional image itself as training matrix, so that the classification performance can be enhanced about 20% comparing LDA, since the training matrix preserves the spatial information of two-dimensional image. However 2D-LDA uses same calculation schema for transformation matrix and therefore both LDA and 2D-LDA has the heteroscedastic problem which means that the class classification cannot obtain beneficial information of spatial distances of class clusters since LDA uses only data correlation-based covariance matrix of the training data without any reference to distances between classes. In this paper, we propose a new method to apply training matrix of 2D-LDA by using WPS-LDA idea that calculates the reciprocal of distance between classes and apply this weight to between class scatter matrix. The experimental result shows that the discriminating power of proposed 2D-LDA with weighted between class scatter has been improved up to 2% than original 2D-LDA. This method has good performance, especially when the distance between two classes is very close and the dimension of projection axis is low.

  • Purpose: This study examined the effects of the symmetrical scapular alignment on the weight bearing of hemiplegic patients in the standing position. Methods: PALM (PALpation Meter) test and Gaitview AFA-50 were used to measure the skeletal alignment of the scapula and the weight bearing loaded on the affected and unaffected sides before and after training. The data was analyzed using a paired t-test on the SPSS 12.0 program for descriptive statistics. A p value <0.05 was considered significant. Results: The mean difference in the scapular alignments on sup. & mid. & inf. area in the hemiplegic side before and after training was $0.93\pm0.50cm$ and $0.58\pm0.43cm$, respectively. There was a significant decrease after training rather than that before (p<0.05). The mean weight bearing on the foot area in the hemiplegic patients before and after training was $9.12\pm5.51N/cm^2$ and $4.36\pm4.11N/cm^2$, respectively,. There was a significant decrease after training rather than that before (p<0.05). The scapuar alignments and weight bearing data on the standing position were grouped around the average (to central point) in the distribution graph. Conclusion: These findings suggest that the symmetrical scapular alignment can serve as an effective means of improving the weight bearing ability of hemiplegic patients.
