The policy agenda setting is the symbolic policy of representing the public at home and abroad in addition to what a role of the government and the ruling party made a great contribution out of a political stream, rather than the policy that was formed by external group. Especially, a policy for migrant workers and married immigrant women is the important policy that will need to be solved in the global era. Accordingly, the purpose of this study is to confirm a factor, which had a decisive influence upon a policy, by examining the decision-making process of 'policy for the married immigrant women' with which the government pushes ahead. A specific plan for achieving this research objective is as follows. It progresses a theoretical discussion about the multi-cultural policy in south Korea and discusses the process that the multi-cultural policy is formed. The advancing stage includes the process of forming a multi-cultural discourse, the differentiation process that a multi-cultural discourse is diversely formed, and the process of being made a policy of multi-cultural discourse, which had been formed by section.

The performance assessment is being importantly recognized and enforced in the education evaluation recently. It is not able to analyze learners synthetically because learners are assessed separately in every subjects and the other activities. On the basis of this problem, we designed and implemented the multi-dimensional processing tool. In this tool, the evaluation results of one subject area have an influence on the other related subject areas. In addition, this system helps teachers to establish and process performance assessment plan by providing all subjects database. And all of the information is processed as a whole and can be used in the counseling and school record. This system is based upon windows and can be extend to web based system later. We expect the performance assessment task can be simplified by using this system and students' ability can be assessed by various methods. This system will contribute to ensure the confidence of public education.

Wireless mesh networks (WMNs) have been increasingly applied in private and public networks during the last decade. In a different context, voice over IP (VoIP) has emerged as a new technology for making voice calls around the world over IP networks and is replacing traditional telecommunication systems. The popularity of the two technologies motivated the deployment of VoIP over WMNs. However, VoIP over WMNs suffers from inefficient bandwidth utilization because of two reasons: i) attaching 40-byte RTP/UDP/IP header to a small VoIP payload (e.g., 10 bytes) and ii) 841 μs delay overhead of each packet in WMNs. Among several solutions, VoIP packet multiplexing is the most prominent one. This technique combines several VoIP packets in one header. In this study, we will survey all the VoIP multiplexing methods over WMNs. This study provides a clear understanding of the VoIP bandwidth utilization problem over WMNs, discusses the general approaches in which packet multiplexing methods could be performed, provides a detailed study of present multiplexing techniques, shows the aspects that hinder the VoIP multiplexing methods, discusses the factors affected by VoIP multiplexing schemes, shows the merits and demerits of different multiplexing approaches, provides guidelines for designing a new improved multiplexing technique, and provides directions for future research. This study contributes by providing guidance for designing a suitable and robust method to multiplex VoIP packets over WMNs.

As a foundational research for formulating a comprehensive operation plan for Ulsan Library, this study has been undertaken to develop directions for the future library services by performing surveys on the users and library staffs. Consequently, first, the users have demonstrated such a high demand for collaborative services, such as make possible variable library services using a single membership ID across the nation. Second, there is a significant difference in the awareness among the two groups in regards to the awareness of promotional methods for the facilitation of the use of public library in Ulsan. That is, while the staffs highly preferred the use of media such as newspaper, magazines, and radios, users demonstrated the converse and, instead, preferred field trip programs. Third, there seemed to be a certain level of agreement by and among the users and staffs in respect of the library's roles such as that of providing diverse education and programs on reading activities, and that of enabling diverse cultural activities such as arts and culture.

Recently performing arts pursue a new rootage of the collective intelligence that seeks experimental thinking and diversity in creative convergence. Understanding in this way the concept of artist's horizontal creation structure and individual communication of the public, this study tries to analyze ${\ll}God's\;Eye\;View{\gg}$, an example of convergent performing art. The result of analysis is as follows. The convergence in performing art could be approached through experiential thinking and diachronic of artists by genre, and the interpretation and its value of the result of work be shared horizontally. ${\ll}God's\;Eye\;View{\gg}$ express a dynamic communication and meaning of poetic image, and shows the experimental creation of convergence and the individual communication ability of collective intelligence as a new value of convergence.

Objectives: This study was conducted to evaluate the task-specific hazards of chemicals used by nail technicians in Daegu Metropolitan City. Materials: A total of 30 nail shops located in Daegu City were surveyed to investigate the major tasks and practices performed by nail technicians and the ingredients listed in nail care products used in shops. We also collected instructions for use and material safety data sheets(MSDSs) of nail care products and compared CAS Nos. of ingredients with the lists of chemicals regulated by the Industrial Safety and Health Act(ISHA) and Chemical Substances Control Act(CSCA). Results: A total of 125 chemical ingredients were found in 468 nail care products used at the 30 nail shops. The most frequently found ingredients were ethyl acetate(72%), followed by n-butyl acetate(71.8%), isopropanol(56%), benzophenone(51.1%), nitrocellulose(46.4%) and ethanol(45.3%). Comparing six tasks, the task of manicuring used the most products at 222 products containing 91 ingredients. Among the 125 ingredients, there are 31 chemicals with occupational exposure limits(OEL) designated by the Ministry of Employment and Labor(MoEL), eight categorized as carcinogens, one mutagen and two reproductive toxic chemicals. In terms of carcinogens, formaldehyde was identified as the only confirmed human carcinogen(1A). We found that there was one chemical with a permissible limit, one special management substance, 18 workplace monitoring substances and ten special health diagnosis substances regulated by ISHA. For CSCA, nine poisonous substances, six substances requiring preparation for accidents and one restricted substance were identified. Conclusions: Based on these findings, formaldehyde was identified as one of the chemicals that should most strictly be controlled for the protection of the health of nail technicians and customers. At the same time, it is necessary to distribute materials with detailed hazardous information of nail care products for nail shop technicians.

This study reports a research which was conducted on how frequently and where the students use the unit circle method while dealing with trigonometric functions in solving the trigonometry questions. Moreover, the reasons behind the choice of the methods, which could be the unit circle method, the ratio method, or the use of trigonometric identities, are also investigated to get an insight about their understanding. In this study, the relationship between the students' choices of methods in solving questions is examined in terms of instrumental or relational understanding. This is a multi-method research which involves a range of research strategies. The research techniques used in this study are test, verbal protocol (think aloud), and interview. The test has been applied to ten tenth grade students of a public school to get students' solution processes on the paper. Later on, verbal protocol has been performed with three students of these ten who were of the upper, middle and lower sets in terms of their performance in the test. The aim was to get much deeper data on the students' thinking and reasoning. Finally, interview questions have been asked both these three students and other three from the initial ten students to question the reasons behind their answers to the trigonometry questions. Findings in general suggest that students voluntarily choose to learn instrumentally whose reasons include teachers' and students' preference for the easier option and the anxiety resulting from the external exam pressure.

The safety of human exposure to an ever-increasing number and diversity of electromagnetic field (EMF) sources both at work and at home has clearly become a public health issue. To date many $in$ $vivo$ and $in$ $vitro$ studies revealed that EMF exposure can alter cellular metabolism, endocrine function, immune activity, reproductive function, and fetal development in animal system. The major parameters found to be altered in cells or individuals following EMF exposure include an increase of free radicals, DNA damage, cancer risk, developmental defect, and reproductive dysfunctions. Epidemiological studies reported EMF can increase life-threatening illnesses such as leukemia, brain cancer, amyotrophic lateral sclerosis, clinical depression, suicide, and Alzheimer's disease has been identified. These effects of EMF exposure differ according to duration of exposure, frequency of waves, and strength (energy) of EMF. In the present review, we briefly introduced the physical properties of EMF and summarized the effect of EMF on human and wildlife animals according to types of EMF, duration of exposure at cellular and organism levels.
