Given the specific mean shift outlier model, several standard approaches to obtaining test statistic for outliers are discussed. Each of these is developed in detail for the nonlinear regression model, and each leads to an equivalent distribution. The geometric interpretations of the statistics and accuracy of linear approximation are also presented.

This article shows Hilbert's Paris address within the context of his career and the mathematics of his day. And the text of Hilbert's speech will be considered in some detail, particularly those parts of it that reflects his vision of mathematics most clearly. At the end it is attempted to show the limitations of the standard view of Hilbert as an advocate of a formalist approach to mathematics.

For grouping the direction of improvement in the survey industry of Korea Standard Industry Classification, watching for internal survey industry, It has a purpose to present the direction of improvement. On the based of UN International Standard industrial classification, survey industry classification of KSIC has not been focused at the special quality of survey industry which is growing fast. Standard Industry Classification of foreign survey has rapidly adapting to survey industry development as detailed and specialized on purpose. thus, Korea's survey KSIC is in urgency to specialize and detail at the field of survey industry as well.

The Environmental Site Assessment System(ESAS) in Korea which became effective as of 2002 is very similar to the ASTM standard practice in United States. Unlike the United States, however, we do not have Phase I ESA, enough environmental professionals with approved training and practical experiences, and detailed guidelines for a governmental action. As a result of comparison the ESAS with the ASTM standard practice, the ASTM standard practice is focused on the Innocent Landowner Defense and has a difference in data search process as well as legal and methodological ways from the ESAS. Therefore, the Transaction Screen Process in ASTM E-1528 standard practice is suggested to reduce the risk potentially produced under on-site assessment and to achieve efficient on-site assessment. In addition, social and executive supports are discussed to more activate on-site assessment. In near future this study is expected to be standardized more in detail with activation of on-site assessment and it is also expected to increase the role and responsibility of environmental professionals considerably.

In this paper, we studied on the effective structure of an e-Learning Korean Support System for foreigner based on computer systems which is to obey the rules of IMS/AICC International Standard regulations based on LCMS and SCORM. The most important task on this study is to support the function of self-study module through the review of the analysis and results of Korean learning and learning customs. We studied the effective PMS detail modules as well as the Standard Competency Module Management System, which related to LMS/LCMS, Learning an Individual Competency Management System, Competency Registry/Repository System, Knowledge Management System based on Community Competency Module, Education e-survey System and Module learning Support Service System. We suggested one of standard Effective Model of learning Korean Support System which is adopted in a various techniques for foreigner.

Recently, the necessity of rapid response to social problems such as disasters and quarantine arising from the complex and diverse social structures has emerged. As the number of large buildings increases, large-scale human damage is expected in the event of a disaster such as fire. To solve this problem, efficient control must be achieved through interfacing with various equipment and facilities installed inside the building. In this paper, we intend to study the interface method for various facilities in the building for efficient control. In detail, the facility standard model is defined by examining the status and specification of building. In addition, we intend to design and propose a standard facility communication data frame to support the protocol applicable to this model.

This paper addresses legislation status of air route design standard of Korea. Korea Ministry of Construction and Transportation's Order Number 300 (March 28, 2001) prescribes that firstly, the design of air routes in Korea should be in accord with International Civil Aviation Organization(ICAO)'s recommendations published in Annex 11: Air Traffic Service and Procedures for Air Navigation Services: Aircraft Operations (ICAO Doc 8168-OPS, 1986), and secondly, United States Federal Aviation Administration(FAA)'s Terminal Instrument Procedures (FAA, 1976). An investigation on the current air route specifications of Korea reveals that they are in accord with neither ICAO's recommendations nor FAA's standards in that the width of Korea's air routes are narrower that the international recommendations and standards. As a member state of ICAO, it is imperative for Korea to follow the international standards. In that purposes, Korea should legislate and regulate the detail standard for air route design. For the legislation, FAA regulations are to be followed because FAA rules contains more detail specifications while ICAO recommendations includes allows a range of policy decisions, which may result in a confusion in practice.

본 연구는 척추경 나사못(Pedicle screw)을 돼지 흉추에 삽입하여 일반적인 CT검사(Non MAR)와 인공물을 줄이기 위한 금속성 인공물 감소기법(Metallic Artifact Reduction for Orthopedic Implants, O-MAR)으로 얻어진 흉추 Axial영상을 4개의 알고리즘(Standard, Soft, Bone, Detail)에 재구성하였다. 이에 얻은 영상을 image J 프로그램을 이용하여 신호대잡음비(Signal Noise Ratio, SNR)와 대조도대잡음비(Contrast to Noise Ratio, CNR)를 주어진 식에 의거하여 측정값을 구하고 흉추 척추경 나사못 삽입술 CT검사에 맞는 관전압과 알고리즘을 알아보고자 하였다. 결과적으로 Non MAR 사용한 경우에는 80, 100, 120, 140 kVp에서 soft 알고리즘이 SNR, CNR이 가장 높게 나타났다. 반면에 MAR를 사용한 경우 80 kVp에서는 Standard 알고리즘이 가장 높게 나타났고 100 kVp에서는 Standard, Soft 알고리즘이 비슷한 값으로 높게 나타났다. 120 kVp에서는 Soft, Standard 알고리즘이 비슷한 값으로 나타났고 140 kVp에서는 Soft 알고리즘에서 SNR, CNR이 가장 높게 나타났다. 따라서 Non MAR와 MAR를 비교했을 경우 MAR를 사용한다고 하더라도 관전압 변화에 따라 모든 알고리즘에서 SNR과 CNR이 증가하는 것은 아니었다. 본 연구는 이후 척추경 나사못 CT검사 영상 평가에 도움이 되는 기초자료로써 선택적인 관전압과 알고리즘 사용으로 영상의 질을 더 높일 수 있는 계기가 될 것으로 사료된다.

본 연구는 임플란트 시술한 환자에 대한 두경부 CT 영상을 4개의 알고리즘(Standard, Soft, Bone, Detail)을 재구성하여 Noise, SNR, CNR 측정값을 정량적으로 분석한 후 최적의 알고리즘을 알아보고자 하였다. 분석방법으로는 Image J 프로그램을 이용하여 재구성한 영상에 관심영역(Region of interest)을 통하여 픽셀값을 계산하였다. Noise, SNR, CNR은 측정부위를 영상에서 인두, 깨물근, 귀밑샘이 있는 지점에 관심영역을 측정하고 mean값과 SD값을 구하였다. SNR과 CNR의 값은 주어진 식에 의거하여 산출하였다. 결과적으로 Standard 알고리즘에서 노이즈는 가장 낮게 나타났으며 SNR 또한 가장 높게 나타났다. CNR은 Soft 알고리즘에서 가장 높게 나타났으나 Standard 알고리즘과는 별 차이가 없는 것으로 나타났다. 따라서 두경부 CT검사에서 구강내 임플란트 착용한 환자 검사에서 Standard 알고리즘이 최적의 알고리즘이라고 사료되며 이 연구의 자료가 두경부 CT검사에서 영상 평가하는데 기초자료로 사용되기를 바라며 다양한 알고리즘 변화로 영상의 질을 더 높일 수 있는 계기가 될 것으로 판단된다.

The objectives of this study is to develop a strategy for the adoption of BPM(Business Process Management) standards and an implementation guideline of the BPM standard for BPM solution developers focusing on BPEL(Business Process Execution Language) which is regarded as the most important BPM standard. In the heterogeneous and distributed IT environments, every type of enterprise software requires standards to enhance interoperability. BPMS(Business Process Management System), which is a type of enterprise software requires BPM standards such as BPEL(Business Process Execution Language), BPMN(Business Process Modeling and Notation), BPQL(Business Process Query Language) and so on to achieve multi-system interoperability and component interoperability with their BPM solutions. It is quite helpful to provide the adoption strategy concerning BPM standards for each type of BPM solution vendors who need the BPM standards. Since the BPEL is conceived as the most important BPM standard and widely adopted by many BPM vendors, we have proposed a reference architecture for BPEL implementation and also developed the detail implementation guideline of core components of the BPM system supporting the BPEL standard. Using the strategy and implementation guideline proposed in this work, BPM solution vendors can establish their own standard adoption strategy and they can also develop their BPM solutions supporting the BPM standards more efficiently.
