본 논문은 IP 기반 네트워크 환경에서 액세스 네트워크간의 글로벌 이동성을 제공하기 위한 방안을 제안한다. 제안 기술은 코어네트워크 영역에서는 빠른 위치 등록을 위해 전송 영역과 제어영역을 분리하였다. 로컬영역에서는 PMIPv6기술을 적용함으로써 네트워크 기반 로컬 및 글로벌 이동성이 가능하도록 하였다. 또한 성능분석을 통해서 기존의 기술과 제안기술의 성능분석 비교를 통해서, 제안기술이 핸드오버 지연시간을 단축함을 확인하였다.

본 연구는 분야별 핵심 연구자를 선별하기 위한 방법론을 다루고자 한다. 핵심 연구자를 선별할 때 가장 흔히 사용하는 방법 중에 하나는 높은 피인용회수(Timces Cited)를 갖는 연구자를 찾는 것이지만 피인용회수가 곧 연구 성과의 순위를 대변한다고 볼 수 없다. 본 연구에서는 특정 학문 분야에서의 연구 성과에 대한 분석을 토대로 핵심연구자를 선별하기 위한 요인들을 수립하고 검증하고자 한다.

5G-based HMD technology grew rapidly in the context of the environment change of convergence technology media and mobile networks in the fourth industrial era. It has also grown into a core technology that transforms our digital visual system. However, there is no research or system that can understand and verify radical visual system changes. Therefore, it is necessary to have an engineering understanding and verification of the diffusion of HMD media imaging devices. Beyond the distinction between virtual and real, research is urgently needed on the new three-dimensional interface of the 21st century through viewer participation. For this reason, research on the algorithm structure of interactive video media using L-System is an essential process and will be a guide to understanding the virtual reality interactive environment.

클래스 로딩에서 핵심은 타입 안전을 보장하는 것이다. 타입 안전은 자바 보안에서 아주 중요한 부분을 차지한다. 하지만 자바 가상 머신에서 타입 안전에 대한 메커니즘은 매우 복잡하고, 접근이 명확하지 않아서 지금 까지 많은 버그가 발생하여 타입 안전에 문제가 되었다. 본 논문은 자바 가상 머신에서 동적인 클래스 로더의 동작을 분석하고, 연산적 의미론(operational semantics)으로 추상화하고 현재 로드되어진 클래스와 추가된 제한 등을 이용하여 이전에 제시되었던 타입 안전에 대한 문제를 분석한다.

The style of war in the $21^{st}$ century became digitalized cooperative union tactic, which relies heavily on the system providing real time information. Critical information is provided during the war from sensing to shooting. Therefore, epochal development in observation, reconnaissance (ISR), commanding (C4I) and precision strike (PGM) are necessary. Application of ubiquitous computing and network technologies in national defense is necessary for carrying out with various types of wars in the $21^{st}$ century. Therefore, the author wants to research core technology sector that can be developed and applied in preparation of ubiquitous national defense era. Also plans for applying recent u-Defense technology to the military sector had been suggested. Particularly, the author have suggested plans for utilizing combined future information technologies such as ad-hoc network, RFID for the logistic supply in construction of u-Defense system. By utilizing these information technologies, combat power and strategic capabilities of the military can be enhanced greatly.

Jane Campion's is a well-known film for a number of reasons, such as for being an Oscar winner, for having been helmed by an emerging director from New Zealand, and for having the reputation of being a feminist film. In this paper, the first scene of was chosen to examine the heroine Ada's language in terms of the gothic genre. Ada is a dumb woman who lives in the era of man's language. She represents the women's social position in the Victorian era but has her own and unique language for communicating with the outside world. The first scene of introduces Ada's own language, using her fingers. Her fingers speak for her all the time instead of her mouth, and there is someone who can understand what she wants to say when all others cannot. How the film depicts Ada's language and how the first scene well summarizes the film's core are examined herein.

Of all the annotations of Rites of Zhou for 2,000 years, there is no single line of history of ore contents related to city building in its current perspective. This is because the definitive evidence of the interpretation of related phrases is regarded as top-level guidelines called "辨方正位(Byeonbang-Jeongwi)", and their specific contents have been discussed in '匠人建國(Jangin-Geonguk)'. The phrases of '匠人營國(Jangin-Yeongguk)', considered to be the key buzzword related to city building, must be reconsidered for these reasons. As such, this paper strives to analyze the system of logic formed by consistent interpretation that flowed for 2,000 years from Han to Qing dynasties, and to discover the principles of city building used in Confucian classics.

The government developed National Competency Standards and expands field friendly education for innovation of industrial field based education training. NCS is the national level of standards that the government systemized knowledge, skills and attitudes required to work in industrial fields by each industry and each level. This study was intended to research NCS education contents of an introduction of dental hygienics, which is a basic major subject among subjects of dental hygiene course, to present learning goals accordingly, and to be used as a basic resource of NCS field oriented classes of dental hygienists through the comparison before and after. In case of the dental hygiene course, dental hygienists are performing important core tasks as clinicians at dental offices. Therefore, such comprehensive and professional performance abilities as scaling, oral prophylaxis and oral health education are required at the fields. The education process and education contents for this should be researched continuously.

The purpose of this paper is to investigate the transfer in mathematics learning, especially focussing on arithmetic and algebra. There are many obstacles at the stage of transfer in learning. In the case of mathematics, each learning contents are definitely categorized by the learning level, therefore these obstacles are more happened than other subjects. First of all, this paper investigates the historical transfer from arithmetic to algebra by Sfard's perspectives. And we define prealgebra as the stage between arithmetic and algebra, which may be revised obstacles or misconceptions happened in the early algebra learning. Also, this paper discusses various obstacles and concrete examples happened in the transfer from arithmetic to algebra. To advance the understanding in the learning of algebra, we consider the core contents of the algebra learning which should be stressed at the prealgebra stage. Finally we present the teaching units of (pre)algebra which are sequenced from the variable concepts to equations.
