Background: Job training influences the overall working environment and worker's well-being. The purpose of this study is to find the relationship between job training and subjective well-being in accordance with occupations and understand the influence of task characteristics-work creativity and task variety (WCTV)-on the effect of training. Methods: A cross-sectional study based on the Fifth Korean Working Conditions Survey was conducted on 50,205 workers in the Republic of Korea. The World Health Oorganization-5 well-being index was used to measure their subjective well-being. The relationship between job training and subjective well-being was divided in accordance with the level of WCTV. Results: Training paid for by employer showed a negative effect on subjective well-being when received for more than 3 days (OR 0.88, p<0.01) in the last 12 months. Training paid for by oneself showed a positive linkage with well-being when the level of training was 1-3 days (Odds ratio = 1.55, p<0.001). This result showed different aspects in accordance with the level of WCTV. For the high WCTV group, the aforementioned results were reaffirmed, but for the group with low WCTV, job training did not show a statistically significant result on well-being. On-the-job training was not related to subjective well-being regardless of the level of WCTV. Conclusion: Job training had different effects on subjective well-being depending on the type and frequency of training, as well as the WCTV. It is imperative to comprehensively apply different types of job training in accordance with the characteristics of occupations to uplift workers' well-being.

Deafs train articulation by observing mouth of a tutor. sensing tactually the notions of the vocal organs, or using speech training aids. Present speech training aids for deafs can measure only single speech ter, or display only frequency spectra in histogrm or pseudo-color. In this study, a speech training aids that can display subject's articulation in the form of a cross section of the vocal organs and other speech parameters together in a single system Is aimed to develop and this system makes a subject to know where to correct. For our objective, first, speech production mechanism is assumed to be AR model in order to estimate articulatory notions of the vocal tract from speech signal. Next, a vocal tract profile mode using LPC analysis is made up. And using this model, articulatory notions for Korean vowels are estimated and displayed in the vocal tract profile graphics.

The purpose of this study was to evaluate the effect of balance training on gait stability. The study population included 17 male high school students who were divided into 3 groups, each of which underwent one of the following types of balance-training programs for 8 weeks: 1 foot standing on cushion foam, trunk muscle training, and inverted body position training. 0, 4, and 8 weeks, the following experiment was performed: The participants were asked to close their eyes and take 17 steps; the stability of forward and sideward movement was determined, and the direction linearity was measured. The results revealed that all the training programs caused a decrease in stride deviation and an increase in the and the stride length, thereby improving the stability of forward movement. All the programs decreased the variation in step width and were thus also effective in improving the stability of sideward movement. The inverted body position training program was considered very effective because the cross point appeared on post hoc graphic analysis after 4 weeks, and the deviation length for 10 m was low, i.e., below 4 cm. All the programs were effective with respect to direction linearity because they decreased the deviation in direction widths. The results indicate that whole-body neurocontrol training is more effective than simple muscle training and local focused balance training, although this neurocontrol training-in the form of inverted body position training-required a longer training period than did the other programs.

Objective: The purpose of this study was to investigate the relative angles and cross-correlation between body segments and ski among four alpine ski turning techniques. Method: 19 alpine ski instructors participated in this study. Each skier asked to perform 4- types of turning technique, classified by radius and level. 8 inertial measurement units were used to measure orientation angle of segment and ski on the anteroposterior and vertical axis. Results: Significant differences were found between types of turning in the segments-ski relative angle on the anteroposterior and vertical axis (p<.05). Although, cross-correlation showed a high correlation between angles of segment and ski, there were significant differences between types of turning. Conclusion: Based on our results, the relative movement and timing between each segment and ski is different according to the turning techniques, so the training methods should be applied differently.

It is important to estimate the true misclassification rate of a given classifier when an independent set of test data is not available. Cross-validation and bootstrap are two possible approaches in this case. In related literature bootstrap estimators of the true misclassification rate were asserted to have better performance for small samples than cross-validation estimators. We compare the two estimators empirically when the classification rule is so adaptive to training data that its apparent misclassification rate is close to zero. We confirm that bootstrap estimators have better performance for small samples because of small variance, and we have found a new fact that their bias tends to be significant even for moderate to large samples, in which case cross-validation estimators have better performance with less computation.

Mining the microarray data accumulated in the public data repositories can save experimental cost and time and provide valuable biomedical information. Big data analysis pooling multiple data sets increases statistical power, improves the reliability of the results, and reduces the specific bias of the individual study. However, integrating several data sets from different studies is needed to deal with many problems. In this study, I limited the focus to the cross platform classification that the platform of a testing sample is different from the platform of a training set, and suggested a simple classification method based on rank. This method is compared with the diagonal linear discriminant analysis, k nearest neighbor method and support vector machine using the cross platform real example data sets of two cancers.

Objective: Dual-task walking deficits impact functional daily life, which often requires walking while performing simultaneous tasks such as talking, thinking or carrying an object. This study is to find out the latest trend of dual-task training's influence on ambulatory abilities of a stroke patient. Design: Systematic review of randomized controlled trials. Methods: This literature review was conducted in Pubmed and Sciencedirect with the follwing key words:stroke, cerebro-vascular accident, hemiplegia, gait, rehabilitation, exercise. 7 studies were chosen in findings by search tool. 3 studies were case study, 3 studies were cross sectional observational study and 1 study was randomized controlled trial. Results: It was found that stroke patients have difficulties in doing 2 motor tasks simultaneously and when they do 2 tasks, one is done in a naturally preferred activity areas. Moreover, when simply applying dual-tasks, the walking speed decreased. Meanwhile, when applying them through training, the speed increased. This showed the improvement of effective task-implementation abilities after dual-task training using task-integration models. Conclusions: In the beginning of the 2000s, dual-tasks were implemented by simply combining walking and cognition or exercise task, and the results of this study suggest that subjects with stroke have difficulty performing dual task. However, the latest trend is to let patients do the dual-task training by combining it with virtual reality. Therefore, dual task training could be performed in a safe in the environment such as virtual reality or augment reality.

A cross-sectional study was conducted among nursing staff of a missionary hospital of Delhi in June 2009. All the nurses were invited to participate in the training programme on breast cancer and techniques of breast self examination (BSE). A questionnaire was administered to all 259 participants seeking information on their level of awareness regarding breast cancer and relevant screening guidelines. With the help of 5 training workshops all the nurses were imparted training regarding the most appropriate technique of doing breast self exams. The mean age of the participants was 35.8 years. Out of a total of 259 nursing staff members 77.2% correctly answered all the 10 questions regarding high risk factors for breast cancer and after the training programme this increased to 100% (p<0.05). Only 65.2% of the participants gave correct responses to all the 8 questions regarding correct technique of performing a BSE, which after the training programme increased to 99.3% (p<0.05). At the baseline only 56.8% knew all the three screening methods correctly and after the intervention 98.7% could correctly mark the responses regarding screening (p<0.05). The actual practice of following the screening guidelines amongst the nursing staff was poor. Only 26 (10.03%) had ever done a BSE, none performed it monthly, 58 (22.4%) had ever gone themselves for a CBE and 18 (6. 94%) had ever undergone mammography.

As one of the useful approaches to enhance safety managers' competencies, this study aims to suggest improvement plans in terms of education in school and on the job for safety managers. Educational needs at schools and job training institutes were surveyed with 321 safety managers in Daejon & Chongju Area. Correspondence with university professors at safety engineering departments via email was also conducted. Collected data were put into the R stochastic program in codified form and quantitatively analyzed through two-dimensional cross-tabulations and a chi-square test. With respect to school education, three academic subjects were examined. Job training was suggested to be conducted as 'training for trainers', which should be more flexible in terms of contents, method, and fees. Periodical investigation of educational needs for safety personnel who are consumers of safety education and training was also proposed.

Purpose: To investigate the satisfaction of students majoring in physiotherapy and to confirm a change of perception on employment decisions after clinical training. Methods: Structured questionnaires were distributed to 500 undergraduate physiotherapy students in 2014. Data from 462 respondents were analyzed using the Mann-Whitney, Kruskal-Wallis, Wilcoxon's signed-rank, stepwise regression, and independent samples t tests. Design: Cross-section study Results: The satisfaction and perceptions of employment decision increased post-clinical training among physiotherapy students who hoped to find employment. After clinical training, the desired employment venues also changed: fewer students desired to work in rehabilitation centers and secondary hospitals, and more desired to work in university hospitals, general hospitals, public welfare centers, and the industrial company health facilities. There were changes in the preferred fields of those who hoped to find employment in the field, as well. There was decreased interest in clinical electrophysiology, sports, and women's health, and increased interest in neurology, orthopedics, and pediatrics. Conclusion: The results of this study confirmed that clinical training changes student' employment decisions and affects their desire to enter specific fields.
