본고는 캐나다의 도시권 획정을 고찰하였다. 구체적으로 캐나다 통계청(Statistics Canada)이 센서스 연도마다 정의하는 Census Metropolitan Area/census Agglomeration(CMA/CA)에 초점을 맞추었다. CMA/CA의 획정은 도시지역의 공간적 정의를 위한 밀도접근, 토지이용 접근, 기능지역 접근 중에서 기능지역 접근에 근거한다. 그러나 CMA/CA는 그 획정과정에서 밀도접근 및 토지이용접근을 토대로 캐나다 통계청이 정의하는 등질지역으로서의 도시지역(Urban Area, UA)을 활용한다는 특성을 갖는다. 실제로 인구 10,000명 이상의 UA는 CMA/CA의 중심부가 된다. 캐나다의 CMA/CA 고찰을 통해, 본고는 우리나라 도시권 획정에 고려할만한 주요사항을 제시하였다.

3각형 및 4각형 요소를 사용한 유한요소법으로 임의의 2차원 비저항 구조에서 점전류원에 대한 전위분포를 구하였다. 이 모델링기술은 종래의 차분법보다 지하의 이상물질이나 지표의 지형을 모델화할 때 보다 더 유연할 뿐만 아니라 보다 더 정확한 수치해를 준다. 또한 이 방법은 해의 정확도에 별 영향없이 격자점을 줄일 수 있기 때문에 계산시간이나 기억용량면에서 경제적이다. 본 논문에서는 이러한 특징을 보여줄 몇 가지 모델에 대한 계산 결과를 소개한다.

The ECC(Elliptic Curve Cryptogrphics), one of the representative Public Key encryption algorithms, is used in Digital Signature, Encryption, Decryption and Key exchange etc. The key operation of an Elliptic curve cryptosystem is a scalar multiplication, hence the design of a scalar multiplier is the core of this paper. Although an Integer operation is computed in infinite field, the scalar multiplication is computed in finite field through adding points on Elliptic curve. In this paper, we implemented scalar multiplier in Elliptic curve based on the finite field GF($2^{163}$). And we verified it on the Embedded digital system using Xilinx FPGA connected to an EISC MCU. If my design is made as a chip, the performance of scalar multiplier applied to Samsung $0.35 {\mu}m$ Phantom Cell Library is expected to process at the rate of 8kbps and satisfy to make up an encryption processor for the Embedded digital doorphone.

The OECD Guidelines for Multinational Enterprises (The Guidelines) was initially promulgated in 1976 as a form of annex to the OECD Declaration on International Investment and Multinational Enterprises. The Guidelines aims at accomplishing the implementation and dissemination of the Responsible Business Conduct. The latest version of The Guidelines, as revised in 2011, directed 47 adhering countries to The Guidelines to set up their respective National Contact Points (NCPs). NCPs are The Guidelines' dispute resolution mechanism for specific instances arising from breach by multinational enterprises of The Guidelines. Korea to date has its own NCP performing its role to offer good offices and facilitates settlement between the parties to the specific instances regarding The Guidelines. However, there has been strong criticism from NGOs and civil society that Korea NCP has not performed well due to lack of transparency and impartiality, especially in the context of the governance of Korea NCP. Under this circumstance, this paper ⅰ) examines current status and problems of Korea NCP, ⅱ) evaluates the core criteria for function and governance of NCPs through a comparative overseas cases study, and ⅲ) suggests improvement plans for Korea NCP.

Our understanding of how brown dwarfs form is limited by observational evidence. We report identification of a L328-IRS as a proto-brown dwarf embedded in an isolated dense molecular core. This source exhibits typical properties of a protostar, however, its luminosity (~0.05 $L{\odot}$) is far below than expected from the least massive protostar by the standard star formation theory. The most likely mass accretion rate (~2.4 10-7 $M{\odot}$ yr-1) inferred from its small bipolar outflow is an order of magnitude less than the canonical value for a protostar. The mass available in its envelope is less than 0.1 $M{\odot}$. These points suggest that L328-IRS will accrete the mass of a brown dwarf, but not that of a star. L328 is found to be fairly well isolated from other nearby clouds and seems to be forming three sub-cores simultaneously through a gravitational fragmentation process. Altogether with these, our direct detection of inward motions in L328 which harbors this proto-brown dwarf clearly supports the idea that a brown dwarf forms like a normal star.

At the extremes of the complexity-performance plane, there are two exemplary QoS management architectures: Integrated Services (IntServ) and Differentiated Services (DiffServ). IntServ performs ideally but is not scalable. DiffServ is simple enough to be adopted in today' core networks, but without any performance guarantee. Many compromise solutions have been proposed. These schemes, called quasi-stateful IntServ or stateful DiffServ, however, have not attracted much attention due to their inherently compromising natures. Two disruptive flow-based architectures have been recently introduced: the flow-aware network (FAN) and the flow-state-aware network (FSA). FAN's control is implicit without any signaling. FSA's control is even more sophisticated than that of IntServ. In this paper, we survey established QoS architectures, review disruptive architectures, discuss their rationales, and points out their disadvantages. A new QoS management architecture, flow-aggregate-based services (FAbS), is then proposed. The FAbS architecture has two novel building blocks: inter-domain flow aggregation and endpoint implicit admission control.

Natural ester has a higher biodegradability, flash and fire points, and a greater permittivity compared to conventional mineral oils. However, natural ester also has a higher pour point, viscosity, and water content. These characteristics hamper circulation and the electrical properties of oil-filled transformer. Thus, this paper applied electromagnetic-thermal-flow coupled analysis method to predict temperature distribution inside 154kV single phase power transformer using natural ester. It modeled in the actual appearance for the tank and winding of the power transformer to improve the accuracy of analysis and applied heat flow analysis that considered hydromechanics and heat transfer at the same time. It calculated the power loss, the main cause of temperature rise, from winding and core with electromagnetic analysis then used for the heat source for the heat flow analysis. It then compared the reasonability of result of measurement analysis based on the result acquired from temperature rise test using FBG sensor on the power transformer.

The robot for narrow space is used in searching, investigating or cleaning. Up to now variety of researches on in-pipe robots have been introduced. However it is still hard to overcome vertical or curved passage. In most cases of narrow space robots are able to travel just aimed diameter which was selected when those are developed. Also, a large percentage of robots are not able to detect the configuration of pipe or circumstance. In this paper we present a robot called PAROYSⅡ for narrow space with vertical and curved passage. This proposed robot is not affected at all to variance of pipes, vertical or horizontal passages, curved pipes, projecting parts and parallel planes. In addition to that, it will perceive the internal configuration of pipe and terrain, which will be not only available to control navigating scheme by itself, but also mappable about the passage which the robot traveled. Core points in the design and structure are introduced and preliminary verification is given.

This study was performed to approach the 2004 case of inferior quality mandu stuffing from the stance of food ethics. The court convicted the producers of inferior quality mandu stuffing and also decided against the plaintiffs who filed a damage suit. The core of the mandu stuffing case was not safety, but the wholesomeness. The principles of food ethics include a respect for life, justice, environmental preservation, and the priority of safety. The virtues of food professionals include wisdom, honesty, faithfulness, courage, moderation, and integrity. A food producer should possess not only the ability but also the morality to make food. The consumer should urge the producers to strengthen their morality and be conscious of responsibility and fairness. The government should organize a system to establish food ethics, and make efforts to reduce wasteful law enforcement. The media should lead public opinion toward justice by doing an unbiased and in-depth report and help establish the idea of food ethics. The necessity of food ethics and the spread of the ethical mind are the most important points of all.
