The number of Multi-cultural Background Adolescent increases every year. It is necessary to show their growing environment in which they are brought up. So this study tries to have a questionnaire research with 588 adolescents and an focus group-interview with 8 service professionals In conclusion, this study suggests developing supplemental programs, supporting systems such as the person participation in the step of the program planning, the community organization networking, professional placement, providing integration service and training program in a family unit.

CIMT(Constraint Induced Movement Therapy) is to improve the function and use of damaged upper limbs by not only confinement of unaffected limbs' exercise but also inducement of affected limbs' one. The purpose of the study is to verify the effect of CIMT by means of motor behaviour test and immunohistochemistry, using animal models. This study was analyzed using 40 male Sprague-Dawley rats as the experimental groups and 40 ones as the control groups. The rats were divided into two random groups : one group as an experimental group which was operated on under anesthesia and removed somatomotor regions with CIMT and the other as the control group without CIMT.Postural Reflex Test, Beam Walking Test, Limb Placement Test and Immunohistochemistry were run on the day 1, 3 , 7 and day 14 following surgery to each 10 rat. As a result, this study demonstrates that CIMT might be an effect method to verify the plasticity of central nervous system as motor behaviour test made all high scores (p<.05) and BDNF was high too in experimental groups.

In recently years, with the growth of social media and the development of mobile devices, the data have been significantly increased. MapReduce is an emerging programming model that processes large amount of data. However, since MapReduce evenly places the data in the dedicated distributed computing environment, it is not suitable to the non-dedicated distributed computing environment. The data replacement algorithms were proposed for performance optimization of MapReduce in the non-dedicated distributed computing environments. However, they spend much time for date replacement and cause the network load for unnecessary data transmission. In this paper, we propose an efficient data replacement algorithm for the performance optimization of MapReduce in the non-dedicated distributed computing environments. The proposed scheme computes the ratio of data blocks in the nodes based on the node availability model and reduces the network load by transmitting the data blocks considering the data placement. Our experimental results show that the proposed scheme outperforms the existing scheme.

Long-term behavior analysis considering construction sequence should be performed in the design and the actual construction of reinforced tall buildings. Most of the analytical studies on this subject, however, has not been applied directly to the structural design and the construction caused by the simple approach. As the axial force redistribution of shores and columns is time-dependent, the actual construction sequence with the placement of concrete, form removal, reshoring, shore removal, and the additional load application is very important. Object-oriented analysis program considering construction sequence, especially time-dependent deformation in early days, is developed. This system is composed of input module, database module, database store module, analysis module, and result generation module. Linkage interface between the central database and each of the related module is implemented by the visual c# concept. Graphic user interface and the relational database table are supported for user's convenience.

The purpose of this study is to evaluate the productivity of elderly employees over 60 years old and to analyze factors that directly or indirectly affect the productivity of elderly employees, based on empirical facts of HR managers. As a result, the factors that have a positive effect on the productivity of elderly employees were attitude and professionalism. The decline in physical capacity due to aging was recognized as a key factor that negatively affected the productivity evaluation of elderly employees. Among the management strategies to improve the work performance, it has been shown that work placement or job redesign according to physical competency contributes to improving the productivity of elderly employees. Also, providing safety education and communication opportunities among workers has a positive effect on productivity improvement. The results of this study suggest that it is important to improve worker productivity by arranging older workers' work experience to be able to demonstrate their accumulated career and expertise and to create a working environment that takes into account physical competence.

Digital transformation is taking place rapidly around the world. As the development of digital technology becomes very fast, more information is expected to be digitized. Therefore, the possibility of cyber threats is increasing in transmitting and storing sensitive information such as personal and financial information online. In this paper, we compared and analyzed information security textbooks for elementary and secondary school students in China, where the recent development of artificial intelligence and digital transformation are rapidly occurring. After we collected related textbooks, textbooks suitable for analysis were selected. Then, we analyzed the external and internal systems of the textbooks separately. As a result of the external system analysis, all the textbook covers were properly produced, but the quality difference was significant among textbooks. In the case of textbooks for elementary school students, the excellence of layout and content placement was noticed. On the other hand, due to the internal system analysis, various contents were not included evenly when looking at the learning contents based on the "information society responsibility" learning goals presented in China. Through this paper, we hope to provide implications for information security-related education and textbook development research.
