HSDPA, Wibro 의 서비스를 시작으로 제 3 세대 이동통신망이 상용화 서비스가 시작되었다. 하지만 3 세대 이동통신 서비스는 아직 사용자에게 기존의 서비스보다 향상된 서비스를 제공하지 못하고 있다. 이동성지원 및 전송방식 측면에서의 발전은 이루었지만 그에 따른 서비스를 제공하지 못했기 때문이다. 다른 한편으로 현재 서비스되고 있는 TPEG 은 서비스의 초기 단계로 버스나 택시에 GPS 칩이나 RF 칩을 장착해 정보를 수집하여 사용자에게 정량화된 방식으로 정보를 제공하고 있다. 본 논문에서는 이러한 3 세대이동통신망의 서비스 문제점과 기존의 TPEG 서비스의 문제점을 동시에 해결 할 수 있으며, 실시간으로 다수의 차량으로부터 영상과 위치정보를 전송 받을 수 있는 서비스를 개발 하였다. 제안된 서비스는 웹 카메라와 GPS 수신기, UMPC, 3 세대이동통신을 할 수 있는 모뎀를 이용하여 전송하며 일반적인 웹브라우저가 설치된 컴퓨터에서 수신한다.

The lunar gravity field is an important source to understand the lunar interior structure, dichotomy and magma ocean of the moon, furthermore it can be used to study the origin and evolution history of the moon. In this paper, we firstly investigated the history of lunar exploration were performed for determining the lunar gravity field, in addition to investigating the procedure of progress related with the lunar gravity field model and gravity observations techniques. After, we determined practically the gravity anomalies of the moon using the new lunar gravity model, SGM90d (SELENE Gravity Model), which were developed by processing the tracking data from SELENE, the japanese lunar mission. Finally, we compared the lunar gravity anomalies from SGM90d model to the those from existing lunar gravity model (LP165P). As results from the comparison, we can make a sense that 4-way Doppler observations of SELENE is very effective to measure the gravity field on the farside of the moon. The precise lunar gravity field model including the farside of the moon which can be more helpful to understand the dichotomy of moon and to establish the detailed distribution of lunar gravity field, such as a mascon.

Recently in the field of archival science, a variety of documentation issues about community, everyday life, political and social movement and human rights are under discussion focusing on minorities' documentation and implementation of social justice. Those issues are especially focused on documentation about minorities and implementation of social justice. These Archival Activism is evolved from academic and social influence since the late 1960s rather than recent changes. The recent Archival Activism is under way in various fields and forms that encompasses both aspects of the mainstream/fringe groups over the world beyond organizations and areas. 4.16 disaster put archival community in korea many challenges. Now is the time to approach with reflections on records of evidence and heal. This study seeks contemporary documentation's assignments through the documentation case of Occupy Wall Street Movement. Firstly, it examines on concept of Archival Activism, origins, and developments. And Based on the documentation case of Occupy Wall Street Movement, it investigates a role of the archival profession carrying out Archival Activism.

This paper is a historical study on mime or pantomime in the chinese theater. What is the origin of chinese mime? This is a very difficult question to answer. But I thought its early model can be found in actions of ancient actors who are believed to precede any genre of theater and actually I could found a very significant proof in historical records which have been ignored generally. It is an episode of Youmeng(優孟) in Chu(楚) dynasty. According to this episode, the history of chinese mime has lasted at least over 2600 years. In my opinion, chinese mime had been organized in ritual genre in early theater and its development had been mostly based on the jiaosehangdang-system(脚色行當制). Most chengshi-movements(程式動作) of zuo(做) and da(打) have been organized in recent several centuries. But a further study on them shows us that the real origin of them is the ancient dance wu(舞). Afterwards the wu(舞) separated into two types of dance the so-called wenwu(文舞) and wuwu(武舞). So we can say that wenwu(文舞) and wuwu(武舞) had a direct influence on most chengshi-movements(程式動作) of zuo(做) and da(打).

Designers are implementing the trial for enhancing human happiness and quality of life. As the happiness factor experienced by each individual is diverse based on human economic growth, absolute design has reached the limitations. A tool to represent the speedy development of change in consumption and problem shooting methods is necessary. Currently, no tool exists that develops in response to changing conditions and subsequent changes. As the solution to this necessity, worm's metamorphosis would be meaningful in design whereby tools exist and necessity as well as solution methods are in advanced change. Rice continues growth following the season, and no single method exists to remove the germs and worms. This study clarified the problems to be resolved by staging the lifetime of rice in 5 stages in environmental changes and conditions. This worm in metamorphosis design is developing brilliantly in biotechnology. However, the environment and conditions that bring happiness to humans do evolve, and this study aims to be the academic research for the design which accordingly replaces the tools.

The advent of available DNA barcoding technology has been extensively adopted to assist in the reference to differentiate the origin of various medicinal plants species. However, this technology is still far behind the curve of technological advances to be applied in a practical manner in the market to authenticate the counterfeit components or detect the contamination in the admixtures of medicinal plant species. Recently, a high resolution melting curve analysis technique was combined with the procedure of DNA barcoding (Bar-HRM) to accomplish this purpose. In this review, we tried to summarize the current development and bottleneck of processing related to the Bar-HRM technology for the practical application of medicinal plant species' differentiation in a viable global market. Although several successful results have been reported, there are still many obstacles to be resolved, such as limited number of DNA barcodes and single nucleotide polymorphisms, in particular, only one DNA barcode, internal transcribed sequence (ITS) of ribosomal DNA has been reported in the available nuclear genome. In addition, too few cases have been reported about the identification of counterfeit or contamination with processed medicinal plant products, in particular specifically the case of technology based infusion, jam and jelly products and components in which it is noted that DNA can be thereby degraded during the processing of these products and components.

Social medicine is recognized as one of medical specialties in many countries. However, social medicine has never been formally introduced to Korea, presumably because the term and its principles were not accepted for some years in the past in American medicine, which has strongly influenced Korean medicine. This paper describes the origins and evolution of social medicine and briefly discusses contemporary social medicine in Korea. Social medicine was initiated in France and Germany in 1848. Since then, it has expanded globally and developed in diverse ways. Included in core principles of social medicine is that social and economic conditions have important effects on health and disease, and that these relationships must be subjected to scientific investigation. The term 'social medicine' is rarely used in Korea, but many of its subject matters are incorporated into preventive medicine which, besides prevention, deals with population health that is inescapably social. However, the Korean preventive medicine directs little attention to the basic concepts and principles of social medicine, upon which systematic development of social medicine can be based. Thus, it is necessary to supplement the social medicine contents of preventive medicine through formalizing the linkages between the two fields. One way of doing so would be to change the title of 'preventive medicine' course in medical colleges to 'preventive and social medicine,' as in many other countries, and to adjust the course contents accordingly.
