This study the presents survey results of a families living with children with disabilities in northern Seoul (Nowon-gu and Dobong-gu) that provides various educational services. This study investigates the current usage and needs of community resources for children with disabilities by the families in the inclusive and segregated care as well as education centers to provide information for the effective implementation of the current system. A total of 109 surveys were distributed and 62 (57%) were returned. 44 families in the 14 inclusive care and education centers as well as 18 families in the 2 segregated care and education centers participated in this study. They were asked to report on access to community resources that include compulsory education, family support, medical treatment, counseling services, commuting support, ways to gain necessary information, current use, and further needs for community resources for their children. Research results indicated that families in two different types of child care centers needed differentiated community services. Parents who use a segregated child care center demanded physical accessibility and increased numbers of highly qualified teachers; however, parents who use the inclusive child care center require the unified information system for the community resources. Survey findings are discussed related to differences between the two types of child care centers. Implications for sharing comprehensive information through child care teachers and directors of child care centers and future research are also discussed.

Objectives There has been a growing concern about the possible carcinogenic effects of the electromagnetic radiofrequency fields emitted from mobile phones. The purpose of this study was to investigate the association between mobile phone use and the development of gliomas in Korea. Methods Our study methods were based on the International Interphone study that aimed to evaluate possible adverse effects of mobile phone use. This study included 285 histologically-confirmed Korean patients 15 to 69 years of age, with gliomas diagnosed between 2002 and 2007 in 9 hospitals. The 285 individually matched controls were healthy individuals that had their medical check-up in the same hospitals. Unconditional logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for use of mobile phones. Results For the entire group, no significant relationship was investigated between gliomas and regular use of mobile phones, types of mobile phones, lifetime years of use, monthly service fee, and the other exposure indices. Analyses restricted to self-respondents showed similar results. For ipsilateral users, whose the body side for usual mobile phone use match the location of glioma, the aORs (95% CIs) for lifetime years of use and cumulative hours of use were 1.25 (0.55 to 2.88) and 1.77 (0.32 to 1.84), respectively. However, the contralateral users showed slightly lower risk than ipsilateral users. Conclusions Our results do not support the hypothesis that the use of mobile phones increases the risk of glioma; however, we found a non-significant increase in risk among ipsilateral users. These findings suggest further evaluation for glioma risk among longterm mobile phone users.

The study aims to discuss on legal prospects of digital collections' fair use through an analysis of treaties and legislations domestic and international. Based on analysis of leading researches and literature, it discusses legal principles of fair use and defines digital collections' concept and types. For understanding the actual legal system on fair use, limitations and exceptions of copyrights which are presented in treaties, such as 'Berne Convention for the Protection of Literary and Artistic Works' and'Copyright Convention', each nation's laws, and judicial precedents. Especially, a legal dispute between 'Technische $Universit{\ddot{a}}t$ Darmstadt' and Eugen Ulmer KG, which debates on library's rights for digitizing their collections without the rightholder's permission, is analyzed. As a result, this study analyzes its implications for the improvement of the existing copyright system in Korea.

When using response surface designs, the experimental trials should be carried out in blocks in case of heterogeneity of conditions. When we use nearly orthogonal blocking, we need evaluate the degree of orthogonal blocking. Graphical methods for evaluating the degree of orthogonal blocking are suggested.

It constructs a database generally and service it does, to use a commercial business DBMS that manages information and to use a retrieval system that supports a search, it adopts the gearing method of the DBMS and information retrieval system. But like this method is inconvenient must operate the DBMS and information retrieval system with duplication to be, there is a weak point where the data management and processing become accomplished with duplication. It presents the DB construction and information search and the management model of the KRISTAL-2002 information retrieval and management system base for the scientific and technical information data management and processing from the dissertation which it sees.

In this paper, we propose a multi-scale crack detection method. This method uses decomposition, composition, and shape properties. It is based on morphology algorithm, crack features. We use a morphology operator which extracts patterns of crack. It segments cracks and background using opening and closing operations. Morphology based segmentation is better than existing integration methods using subtraction in detecting a crack it has small width. However, morphology methods using only one structure element could detect only fixed width crack. Thus, we use decomposition and composition methods. We use a decimation method for decomposition. After decomposition and morphology operation, we get edge images given by binary values. Our method calculates values of properties such as the number of pixels and the maximum length of the segmented region. We decide whether the segmented region belongs to cracks according to those data. Experimental results show that our proposed multi-scale crack detection method has better results than those of existing detection methods.

Designing a reliable multicast-based network that scales to the size of a multicast group member is difficult because of the diversity of user demands. The loss inferences of internal nodes by end-to-end measurements do not require the use of complete statistics because of the use of maximum likelihood estimation. These schemes are very efficient and the inferred value converges fast to its true value. In the theoretical analysis, internal delay estimation is possible but the analysis is very complex due to the continuity property of the delay. In this paper, we propose the use of a bottleneck location estimator. This can overcome the analytical difficulty of the delay estimation using the power spectrum of the packet interarrival time as the performance metric. Both theoretical analysis and simulation results show that the proposed scheme can be used for bottleneck location inference of internal links in scalable multicasting.
