  • This study was to investigate the effects of the sensory-motor training program childhood body concept and to investigate the difference between the control group and experimental group. Subjects of the study were compared with children whose age varied from three to four years old, where I.Q was over 100. The major things of this study was as follows, First, sensory-motor training program was effective with regards to body concept improvement among the three-, four-year-old children. Second, both the experimental group trained by sensory-motor program and the control group trained by cognitive-perceptual training program were revealed a meaningful performance. But, sensory-motor program offering subcognitive sensory body experiences yielded higher mean gains in scores than a cognitive-perceptual program. Sensory-motor learning is more effective than verbal learning is promoting body concept reflected in the ability to draw human figures.

  • A Problem of low-velocity forced convection in a channel flow with heated wall is of practical importance and widely considered in the design of devices such as heat exchangers, and electronic equipments. Therefore, there is an urgent need for improving heat transfer performance of heated wall in the channel. In the present study, an oscillating vortex generator method is proposed to enhance the heat transfer in a channel. In this method, a rectangular bars are set in the upstream of heated region of the channel. The bars are forced to oscillate normal to the inflow, and then actively and largely generates transverse vortices behind the bars. As a result, this apparatus can enhance the heat transfer rates remarkably. Because of the interaction between the flow and oscillating bars, the variations of the flow and thermal fields become time-dependent state.

  • From the scientific point of view, any regulation of the emissions of toxic air pollutants in general, and ETS or VOCs in particular, will inevitably be based on exposure levels and consequential health effects, data of this nature is still lacking for most of ETS and VOCs. In this context, the importance of personal monitoring measurements of ETS and VOCs in relation to risk assessment has been emphasized previously.(omitted)

  • There are two kind of method to perform a safety management in industrial field. One is a management by safety manager employed in company and another one is safety management by acting agency. In case of the company that managed by the acting agency dose not coincide with the state of company and safety management performance because of the safety management is carry out by periodically. Therefore it is considered that the sufficient safety management is difficult. And a company that employ a safety manager also show a low level of safety management compare with the advanced country in view of safety and health. From the statistics of accident rate of the company, it is necessary that an improved safety management through the studying and analysing a coverall matters for the company that managed by acting company.

  • Regarding the characteristics of fatal electric shock accident during the past 10 years, fatalities occurred more frequently in July & August, and AM 10-12 PM & 14-16. Also, the electric shock accident is occurred more frequently in the age group from 30 to 40. Especially, the fatal electric shock accident in construction industry covered more than half of total industry. Therefore, it is strongly requested for the protection technology of an electric shock from the low voltage electric path, grounding method and workers. The aim of this study is to propose the policy about the equipment performance standards and/or worker's safety standards to revise the standards for preventing electric shock accidents on safety workings.

  • Zohar(1980) emphasized the influence of social, organizational, and psychological context in occupational safety and health study. With this research trend, Neal, Griffin, and Hart(2000) developed a sequential safety climate model. In this paper, author examined the usability of their model the relationships among safety climates, safety knowledge, safety motivation, and safety performance(safety compliance and safety participation). The author conducted a survey to 207 manufacturing workers, and the chief results of statistical analysis are as follows : 1) the leadership has positive effects on safety knowledge and motivation, 2) the precaution activities has only positive on safety knowledge, 3) the safety system has only on safety motivation, 4) the safety knowledge and motivation have positive effects on safety compliance and participation.

  • The employment rate of university graduates has been decreasing significantly recently. With the advent of the Fourth Industrial Revolution, the demand for software employment has increased. It is necessary to analyze the factors for software employment of university graduates. This paper proposes explainable software employment model of university graduates using machine learning and explainable AI. The Graduates Occupational Mobility Survey(GOMS) provided by the Korea Employment Information Service is used. The employment model uses boosting machine learning. Then, performance evaluation is performed with four algorithms of boosting model. Moreover, it explains the factors affecting the employment using SHAP. The results indicates that the top 3 factors are major, employment goal setting semester, and vocational education and training.

  • Fifteen years have passed since the enactment of the Industrial Technology Innovation Promotion Act, which promoted industry cooperation activities for universities. Therefore, the study analyzes the relationship between the university's industrial cooperation activities and the college graduates' starting salaries and provides policy suggestions on improving the direction of university-industry cooperation. The study used nine-year panel data from Graduates Occupational Mobility Survey (GOMS) to conduct an empirical analysis and found that starting salaries of college graduates were not significantly higher if the university only participated in basic industry cooperation activities. On the other hand, when the quality of university-industry cooperation activities was higher, such as job search support, the starting salary of college graduates was higher. The findings suggest that university-industry cooperation activities must focus on qualitative performances rather than quantitative approaches.

  • Objectives: The purpose of this study was to examine the change in exposure concentration in the cleaning process after installing a local exhaust system. Methods: Dichloromethane measurement was conducted according to the KOSHA Guide (A-19-2019). Results: After the local exhaust device was installed, a total of three measurements were conducted, including temporary work environment measurements, and all of the measurements did not exceed the DCM exposure standard, but were more than 50% of the DCM Time Weighted Average((8-TWA) Conclusions: It is thought that the local ventilation system of a small business needs not only support for the initial installation cost, but also educational support for maintaining the performance of the local ventilation system and support for consumables (adsorbents, filters, etc.) that incur periodic costs.

  • Objective : The purpose of this study was to identify effects of intensive sensory integration (SI) treatment and home-program for a child who has a sensory integration disorder. This study also examined whether the positive effect is long-lasting by a follow-up test. Method : A boy with sensory integration dysfunction underwent an intensive SI treatment for 2 weeks. The intervention was consisted of 9 sessions and duration of the each session was 40 minutes. Sensory diet and Wilbarger protocol was provided as home program. The child's sensory function was evaluated before and after the SI intervention. Five month later, re-evaluation was executed for follow-up purpose. Results : In the evaluation after the Si intervention, the child's sensory defensiveness was decreased. Praxis, visual perception, sensory regulation dysfunction (sleep function), affective stabilization and performance of activities of daily living are also improved. In the re-evaluation after the 5 month later, the self-regulation ability, especially sleep function, has been maintained and the visual perception was developing continually. However, the child showed some affective regulation such as bothering his mother and losing his temper. Conclusions : The intensive SI intervention showed positive effects in terms of SI function improvement and the effect lasted long without any additional therapeutic intervention.
