An Integrated Management Platform, which plays a core role in managing u-City, intelligently control various infra-structure components by accommodating a large number of sensors and devices; and analyzing data received from these sensors and devices through wired/wireless sensor networks. In this paper, the services provided by the integrated management platform for u-City are classified into common application service, operational management service, and platform gateway service, and furthermore detailed functions for each service are defined. These functions, through their roles and information flows, will clarify the requirements of the integrated management platform, and through their addition and modification will be utilized as a reference model for the functional organization of the integrated management platform.

Contemporary costume by the 'Deconstruction' from the outside has shown disclosure, destruction, poverty and analysis. The conclusion of this thesis as follows, 1. The Deconstruction of disclosure by infra disclosed the underwear and inner structure outside, which has deconstructed a fixed idea i.e.'underwear must be in outwear', modesty versus immodesty and disclosure versus concealment. 2. The Deconstruction of destruction originated in punk look has rejected traditional manners and utility, at the same time, it has shown the ambivalence i.e. completeness versus incompleteness, making versus destructing by slashes, rips, fringes. 3. The Deconstruction of poverty has appeared as French avangarde mode, little black dress by Chanel, second hand style by hippy, blue jean, granny look, especially Rei Kawakubo's poor look influenced by Zen Aesthetics and post punk. It has looked like old and worn out dress by doing patchwork, dye, decolor, rip, fray, which has shown the decentring by concealing the body than disclosing, rejecting snobbery. 4. The Deconstruction of analysis, seemingly partial and patched is a violation only of our expectation of clothing's unbroken entity though it has looked like a fragment. The completeness and coherence of it is made more evident by its breach, void, and bond like a poetic language. As the result, disclosed, destructed, poor, and analytical costumes has expressed as an escape from the appearance which traditional aesthetic concept had pursued.

Mobile IPv6 services exposes its vulnerability when a mobile node is roaming across the subnets which belongs to the different domains. The AAA Infrastructure Is strongly recommended when the ISPs need to authenticate the mobile user come from the different domains. In addition to the basic requirements for AAA service, the authentication latency and AAA message overhead should be minimized for contiguity of the service. This paper considers the roaming service with AAA infra structure in Mobile IPv6 and proposes the key distribution method to authenticate the mobile node with secure manner by reducing and optimizing the exchanged messages for AAA entities.

Painting is well regarded as a stratified structure by the conservators and restorers. Hence, the scientific methods have been developed for the study of the interal layer of paintings. Examples of such methods are X-ray, infra-red, and ultra-violet photography. A more direct method is to look at the painting in cross section under the microscope and to analyze pigments using an electron probe X-ray micro analyzer(EPMA).In this research, I study and analyze twenty two Korean paintings of self-portraits including the first oil painting of Hui Dong Koh's self-portrait stored in the museum of Tokyo National University of Fine Arts and Music, employing these scientific techniques. The small fragments taken from the ground layers of the early oil paintings(1915∼1942)are analyzed using the EPMA. According to their main materials, the ground layers can be classified into five types ; 1. Lead white layer and double layer of calcium carbonate and lead white, 2. Zinc white with some mixiture of lead white, 3.Titanium white with some barium white, 4. Barium white, 5.Double layer of titanium white and zinc white.

최근 글로벌 경쟁이 치열해 지면서 가격경쟁력이 뒷받침되지 않으면 신흥 시장에 대한 대응이 어려워져 가격경쟁력의 중요성이 부각되고 있으며, 구조적인 비용 상승 추세로 기업의 원가 압력이 증대되고 있고, 이러한 변화된 경쟁 환경에서 생존하기 위해서는 전체적인 생산성 향상이 필수이다. 가격경쟁력 강화 및 원가압박을 해소하고 품질, 가격, 납기 전반에 모방할 수 없는 차별화된 경쟁력의 확보는 생산성 향상을 통해서 실현할 수 있고, 생산성 향상을 통한 경쟁력 있는 기업 육성은 우리 제조업을 발전시키는 토대(infra structure)이며, 기반 시설의 확충이다. 본 연구에서는 현재 외국의 혁신방법을 우리산업 현실에 대한 고려 없이 단순 도입으로 국내 실정에 맞지 않아 상당한 시행착오를 격고 있으며, 국내에 벤치마킹 할만한 제조혁신 방법론이 거의 없고, 벤치마킹하려고 해도 기업의 영업비밀이라 배우기도 쉽지 않은 상황에서 우리산업 현실에 맞는, 중소 중견기업의 맞춤형 생산성 혁신 지원도구로 중소기업의 자생적인 혁신을 위해 중소기업의 수준에 맞는 제조혁신 방법을 국내외 제조혁신 전문가로 컨소기엄을 구성하여 한국생산성본부에서 개발된 한국형제조혁신 방법론을 제조기업에 적용하여 성공적인 결과를 다른 기업에 적용 할 수 있도록 하는데 목적을 둔다. 연구목적을 달성하기 위해 문헌연구를 통해 일본의 TPS(Toyota Production System), 미국의 Lean 시스템 및 6시그마 시스템에 대하여 살펴보았고, 한국형 제조혁신 모델인 KPS(korea production system)를 통신장비 제조회사인 M. 사에 적용하여 실증하였으며, 그 결과 우수한 성과를 보임을 확인할 수 있었다.

Level of Service(LOS) is classified A through F in highway system (KHCM), usually using LOS C in express way and D in national road. (LOS C denotes 75% of capacity) Meanwhile in Railroad System, there is no clearly defined LOS, and the daily demand in infra-structure planning has been used. It is very important that LOS provides consequently a consensus of opinion between users and operators because there is a close relation between user demand and level of services. Considering this, there should exist clearly defined Level of Services in Railroad System Planning so that demand can be predicted precisely.

With the recent introduction of supply chain management (SCM), quality management has extended from within companies to between companies. As a result, supply chain quality management (SCQM) has received increased attention. However, existing SCQM studies only focus on what impact quality control in supply chains have on company performance while virtually no studies examine quality control efficiencies. This paper, therefore, evaluated the SCQM efficiency of a parent company and its partner companies by using Data Envelopment Analysis (DEA) based on the Quality Collaboration Index for Supply Chain Management (QCI-SCM) conducted by the Korean Standards Association for its 'Quality Innovation-Based Building and Expansion of Business.' Study results showed that a parent company and its partners showed an overall average efficiency of approximately 80% (parent company 80.37%, partner company 79.05%). By also performing a discriminant analysis based on the calculated efficiency scores using DEA, factors that made companies efficient or inefficient were different between the two groups. In parent companies, efficiency and inefficiency were determined by factors such as communication, infra-structure, support, delivery of quality, and benefit sharing, whereas in partner companies, talent development, infrastructure, crisis management, and delivery of quality were the determining factors. In this paper, we examined the efficiency of SCQM and analyzed them from the perspective of both the parent company and partner companies to offer strategic SCQM insights.

This paper develops a Sustainable Regional Economic Growth Model (SREG) which estimates the relation of labor population change and employment increase in each occupation and maximum limits and minimum requirements of employment increase by labor population change in a specified region using multiplier theory. To develop the proposed model, sustainable regional economic growth is defined as a steady increase of labor population over a long term period and the limit of employment increase is defined as the estimated labor population change in the region with no need for commutation from the surrounded areas. Developed model was applied to 67 county in Pennsylvania State and the results revealed that the investment in infrastructure occupations, such as transportation, warehousing, utilities, information, communication, and other public utilities, maximizes the effects for increasing employment, whereas finance, insurance, and real estate occupations have minimum effects for increasing employment. Calculated minimum requirements of occupations show that infra-structure occupations is a critical factor for labor population change and maximum limits of occupations show that agriculture and finance occupations are difficult to increase independently.

We compiled near-infrared photometric and polarimetric catalog of sources in ~3 $9^{\prime}{\times}69^{\prime}$ size field in the eastern side of the Large Magellanic Cloud (LMC). This catalog lists all 1969 sources which are brighter than 14 mag and which signal to noise ratio of degree of polarization is greater than 3 in the J, H, and Ks bands. The photometric and polarimetric data were simultaneously obtained in J, H, and Ks bands using SIRPOL, an imaging polarimeter of the InfraRed Survey Facility (IRSF), in 2008 December and 2011 December. We classified the objects into several groups based on their locations on the color-magnitude diagram and compared their general properties of polarization. We measured wavelength dependence of this field to verify interstellar polarization of the LMC which occurred from the dichroic extinction. We also discuss the polarization structure in this field with the results from molecular cloud studies.

While attention has been paid to 'core information poor' with low-level information literacy, public libraries are to be social agencies to set policies, and are to provide them with cultural experiences and services as well. In this regard, this study intends to shed light on the current status of public library services for such 'information-poor' as the urban poor, the handicapped, and the aged in Busan metro area. Exploring the statistical data, observations and interviews, the study attempts to illustrate current status and trends. It, specifically, focuses on the following characteristics of information service strategies: types of services provided; infra-structure including facilities and specialized collection; and, barriers and limitation of library and information use.
