Wireless mesh networks for public safety and disaster have been developing in a direction from TETRA(TErrestrial Trunked RAdio) to take advantage of the Public Safety-LTE(Long Term Evolution) technology. In Korea, the Disaster Safety Network Building Project has been promoted in order to unify disaster communication systems among disaster response agencies. In this study, the trends of the network construction for national disaster communication and corresponding representative cases of overseas have been analyzed. Through this process, the disaster communication area in line with the purpose of communications. As a result, the disaster communication can be divided into five distinctive areas: the control, the response, the on-site, the victim and the alarm communications. Based on the re-designed communication areas, quality requirements have also been re-organized in this study. Ultimately the construction method for the Disaster Communication systems without exclusion zone will be presented.

This study examines how East German police was absorbed into the Unified Germany Police. The experience of Germany suggests a few implications and preview points when the two Koreas unify how North Korean police to absorb and utilize, which is the purpose of this study. According to a study, in a unified transition in North Korea, 110,000 police forces is needed in order to cope with an outbreak of rioting and public disorder in North Korea. It is never easy, in an imminent unification, to secure a large number of police forces in a short time. We cannot help making the best use of North Korean police. At this point, the German case would be nice for us to see the implications presented. Because West German police led the integration of East Germany in the People's Police, and reemployed them under certain conditions. As a result, by taking over the People's Police of North Korea without friction with the security of the high security demand required by the unification process in the future, it is necessary to achieve seamless integration of the North-South police.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social and communication impairments, as well as repetitive and restrictive behaviors. The phenotypic heterogeneity of ASD has made it overwhelmingly difficult to determine the exact etiology and pathophysiology underlying the core symptoms, which are often accompanied by comorbidities such as hyperactivity, seizures, and sensorimotor abnormalities. To our benefit, the advent of animal models has allowed us to assess and test diverse risk factors of ASD, both genetic and environmental, and measure their contribution to the manifestation of autistic symptoms. At a broader scale, rodent models have helped consolidate molecular pathways and unify the neurophysiological mechanisms underlying each one of the various etiologies. This approach will potentially enable the stratification of ASD into clinical, molecular, and neurophenotypic subgroups, further proving their translational utility. It is henceforth paramount to establish a common ground of mechanistic theories from complementing results in preclinical research. In this review, we cluster the ASD animal models into lesion and genetic models and further classify them based on the corresponding environmental, epigenetic and genetic factors. Finally, we summarize the symptoms and neuropathological highlights for each model and make critical comparisons that elucidate their clinical and neurobiological relevance.

In order to assess the level of atmospheric pollution and to contribute the hearth improvement of residents in Taejon city, the authors were measured the concentration of air pollutants(CO, SO$_2$, NO$_2$, TSP, Pb, Cd, Cr) at three places of the control road in Taejon. The investigative research performed bimonthly from May 1993 to September 1993, and the places were the underground shopping stores of Taejon station, Dongyang department store and provincial goverment areas. The results of statistical analysis are as followings. \circled1CO :0.569~0.966ppm \circled2SO$_2$：0.084~0.170ppm \circled3NO$_2$:0.0045~0.022ppm \circled4TSP：249~299$\mu\textrm{g}$/㎥. \circled5Pb :0.366~1.157$\mu\textrm{g}$/㎥. \circled6Cd：0.016~0.025$\mu\textrm{g}$/㎥. \circled7 Cr : 0.198 ~0.290$\mu\textrm{g}$/㎥. The mean concentration of SO$_2$in Dongyang department store area was 0.17ppm, and it exceeded the ambient air quality standard by 0.02ppm. The concentration of TSP was higher than a standing rule of public hygiene, and it was very near to a standing rule of environmental preservation. The standing rule of indoor air pollution in underground shopping store have two different laws, the public hygiene and the environmental preservation. Therefore, it was difficult to judge what to do in such circumstance. In regarding to the laws, an environmental standard for air pollution in the underground space must unify into the standard of public hygiene.

Information technology will inevitably and profoundly alter every aspect of university life. New information technologies are creating new patterns in the research and teaching, with networks enhancing information sharing and data transmission. The revolution in information technology requires that universities integrate information technology with their traditional missions of teaching, research, and public service. Enhanced mode of information access and changing information-seeking behaviors suggest the need for new library services. New technologies have opened up many new services options for libraries. The nature of and potential for new information services suggest that libraries should become better connected with other campus units. Some of these issues will no doubt be addressed by the a n.0, pplication of new technologies and by building campus information infrastructure. An important element of the needed change for enhancing the library information services is the integration of the libraries and computing centers. Libraries and computing centers deal with the same commodity-information and delivering information. For the sake of scholarship and research, the two must devise an integrated a n.0, pproach to delivering the common commodity. Computing centers have special skills in system development and telecommunications. Libraries have good human interface skills and skills for organizing knowledge. Together they could be a particularly productive team. Noting this, some universities have created new information service units which unify the present-day computing, library and telecommunication functions. Existing models range from true merging to situations where some cooperative activities are being conducted. The purpose of this study is to suggest the direction in developing of information services in academic libraries by examining the changing information environment and trends of integrating libraries and computing centers. This paper inquires into the changing information environment, the impact of imformation technology on universities and libraries, some casses of integration of academic libraries and computing centers, and effects of integration of two and suggests the developing direction of information services in academic libraries.

The important and main purpose of revision of Incoterms rules are to adapt it to contemporary commercial practice in world trade, and to contribute to great service to foreign trade. Incoterms$^{(R)}$ 2010 revision basically focuses on trade terms to be used for any mode or modes of transport at compared Incoterms 2000 gouping in four basically different categories, and presents trade terms to be used for traditionally seaborn trade. Therefore the former is for trading in manufactured goods involved in containerization, the latter is for trading in community. This study focuses on a motive of revisions and main features of the Incoterms$^{(R)}$ 2010 rules, an outline, the problems and alternative of them. In conclusion, I would like present as follows; (1) Although they only concerned the models of delivery and critical point, they only say a few of the many factors of a sale contract, that is to say for the devision of fuctions, costs and risks between the contracting parties as supplement law, but the guestion of the legal position of Incoterms rules is various in different countries and scholars. in spite of that, it must focus on the practical application and the wide acceptance of Incoterms rules in world trade. (2) Although they present more simple and clear, unfricative, than Incoterms 2000 rules, in order to help users, the need to unify consistently and fully explanate in contents and expression. (3) Introduction and guidance note of Incoterms$^{(R)}$ 2010 rules basically focuses on the understanding of a motive of revisions as compared Incoterms 2000 rules. But it is well advised to do this on the assumption of understanding the various basic meaning of terms. (4) finally, trade concerned regulations take account of the reflection for the application to domestic and international trade according to formally reconization of availability for both trade.

After emerging of Microsoft Kinect, the interest in three-dimensional (3D) depth image was significantly increased. Depth image data of an object can be converted to 3D coordinates by simple arithmetic calculation and then can be reconstructed as a 3D model on computer. However, because the surface coordinates can be acquired only from the front area facing Kinect, total solid which has a closed surface cannot be reconstructed. In this paper, 3D registration method for multiple Kinects was suggested, in which surface information from each Kinect was simultaneously collected and registered in real time to build 3D total solid. To unify relative coordinate system used by each Kinect, 3D perspective transform was adopted. Also, to detect control points which are necessary to generate transformation matrix, 3D randomized Hough transform was used. Once transform matrices were generated, real time 3D reconstruction of various objects was possible. To verify the usefulness of suggested method, human arms were 3D reconstructed and the volumes of them were measured by using four Kinects. This volume measuring system was developed to monitor the level of lymphedema of patients after cancer treatment and the measurement difference with medical CT was lower than 5%, expected CT reconstruction error.

This paper, so far to analyze the research trends in the issue that has been discussed for the introduction of private investigation institutions, by projecting its suggestion, want the investigation purpose of presenting the desirable introduction direction. The analyzed issue was extracted for existing research material on the introduction of private investigation institutions. Investigators pointed out issue is the name, business scope, corporate, qualification system (eligibility criteria and test), education, association establishment, regulatory agencies, has been included in the eight categories such as legislation form. For the name, I think there is a need to unify under the name "detective". For the scope of work, the amendment is difficult law, place an overview of the general business rules, more specific and detailed investigation business content, to discipline through the ordinance it is possible to be rational. Private investigation institutions, I think the need for limited operations of the corporation. For education, the new education and re-education on a regular basis I do for the private investigation workers. You must be one of the National Police Agency to the management authority. Legislative form, not to be defined by its own law, the revision of the security law, but that is to complement the provisions for private sector research system is effective.
