Like a violence occurred by security guardians in the Yoosung or SJM Enterprise, a series of security company in Korea has repeated illegal conduct. So human rights violations are getting to be very heavy. The National Police Agency, the controller of the Security Services Industry Act, requires stricter regulations for the defense industry direction. here followed the research about some provisions in the Security Services Industry Act relating to 'the collective civil appeals spot' examining the contents of the Problems and discussed about it.

2005년 1월, 정부혁신지방분권위원회의 ${\ulcorner}$국가통계인프라 강화 방안${\lrcorner}$ 의 내용을 보면 통계청의 지방통계사무소를 지역통계센터로 개편하여 지역통계의 기획, 표본설계 등에 관한 기술지원을 담당하는 것으로 기술되어 있다. 향후 모든 기관의 통계조사업무를 수탁, 대행하는 기관으로의 발전을 목적으로 한다. 통계청에서는 이 역할을 담당할 인재를 양성하기 위한 교육과정을 통계교육원에 요청하여 개설한 바, 상반기와 하반기 2회 실시하였다. 교육과정명은 ${\ulcorner}$통계개발기획과정${\lrcorner}$ 으로 2주간 실시하였고, 교육대상자는 현재 지방청 및 지방사무소에 근무하는 직원으로 한정하였다. 교육과목으로는 이론과 실무가 접목되고, 교육 이수 후에 바로현장에서 활용 가능하도록 구성하였으나 결과론적으로 보았을 때 추가되어야 할 교육내용들이 나타났다. 조사기획 즉, 조사방법과 조사기획서 작성에 치중한 교육내용은 향후 지역통계센터에서 어떤 역할을 부여받느냐에 따라서 좀 더 체계화되지 않을까 생각된다. 전체 팀원들을 위해서는 일련의 조사기획에 대한 이론과 실무경험이 중요하다. 또한 지방자치단체의 통계DB구축에 도움을 주기 위해서는 그 부분에 대한 이해도 필요할 것으로 판단된다. 특히 관리자에게는 리더십과 관리능력 그리고 대인과의 커뮤니케이션 스킬, 분석능력 등이 추가적으로 필요할 것으로 생각되었다.

Recently, usage of swearing words on web board is the most typical Internet negative-functions. For this, technical method is proposed for blocking swearing words or sentences by analyzing swearing words usage types and behaviors. This system consists of 3 steps. Firstly, a survey, analysis of swearing words on web board and algorithm proposal for blocking these words must be studied. Secondly, sufficient and concrete opinion researches about every generations for measuring swearing degree must be accomplished. Finally, implementation on web board by programming will be done. This paper, in the first, deals with usage analysis of swearing and algorithm developement for solving these problems.

XML을 가장 효율적으로 활용할 수 있는 B2B 시스템 구축 시 가장 중요한 부분은 모델링을 어떻게 하느냐 일 것이다. 기존의 관계형 데이터베이스에 저장된 정보를 XML 문서로 변환하는 것뿐만 아니라 신규로 정의하여 사용하는 정보에 대하여서도 확장성 있고 만족할 만한 성능을 보장하도록 구조화시킬 것인지가 관건이다. XML 문서는 그 자체로 하나의 객체이며 객체지향 모델링의 표준인 UML을 사용하여 문서정보 뿐만 아니라 시스템 전체를 모델링하는 것이 가장 바람직한 접근 방법이다. 따라서 본 논문은 계층구조를 갖는 XML 데이터를 관계형 데이터베이스로 저장이 가능하도록 하는 모델링 방법론을 제안하였다. 이를 위하여 우선적으로 객체지향 설계언어인 UML를 이용해서 클래스 다이어그램을 도출한 후, 클래스 다이어그램에 의해서 XML DTD 설계를 위한 XML 모델링을 소개하고 이들의 모델링으로 교환되는 XML 데이터를 효율적으로 저장하기 위하여 관계형 데이터베이스 스키마 설계를 위한 데이터 모델링 방법을 제안하였다. 아울러 변환 방법에 의해 관계형 데이터베이스 스키마 스크립트를 구현했다.

본 논문에서는 중복되지 않는 서로 다른 카메라의 영상을 활용한 동일 객체 판단 및 추적 기술에 대하여 소개한다. 영상분석에서 색상 정보는 가장 기본이 되는 중요한 정보라 할 수 있다. 특히 색상 정보를 이용하는 히스토그램은 일반적으로 추적, 인식 등에 많이 사용되고 있으나 이동 객체나 조도 변화 등에 따라 성능에 차이를 보인다. 이러한 문제점을 해결하고자 본 연구에서는 동일 객체 판단을 위해 대표적으로 사용되는 히스토그램 정합의 두 알고리즘(HSV 공간에서의 Histogram matching 방법과 RGB 공간에서의MCSHR 알고리즘) 결합을 통해 분할 히스토그램은 객체를 3조각으로 나누어 전체와 각각의 히스토그램을 구하며 MCSHR을 RGB공간이 아니 Hue 공간 히스토그램으로 변경하여 유사도를 도출 하였으며 조도 변화에 강인한 모델을 만들기 위해 Controlled equalization기법을 사용하여 원 영상의 히스토그램의 확률과 평활화한 히스토그램의 확률 융합을 시도 하였다. 해당 실험의 비교 결과 기존 HSV공간에서 Histogram matching을 통한 유사도 비교보다 12.9% 향상된 정합율의 결과를 보였다. 또한 영상 정보와 스마트 기기를 통한 인식 방법의 융합을 통해 영상 내에서 동일 객체 판단에 대한 추가 정보 제공에 대해 방법론 적인 부분을 제안 하였다.

One of the most important functions digital libraries need to offer is to help users find necessary information in a distributed environment in the most efficient and effective manner. In order to meet the goal, it is desirable to link scattered pieces of information and present them as a logically coherent whole when the user wants it, so that he or she doesn't need to know their physical location. The virtual document is an integrated document that the total or part of the physical documents stored in a specific repository are linked dynamically. Our MIRAGE-III digital library system provides a content-based retrieval of physical documents and the virtual documents in XML. This system provides a retrieval of partial documents, attributes and hierarchical structures and linked-documents based in structured documents like XML or SGML. In this paper we describe a methodology of design and implementation of the query processor and retrieval server in the MIRAGE-III digital library system.

The partial oxidation of methane with nitrous oxide on silica-supported metal-oxygen cluster compounds, known as heteropoly acids, has been studied. The effects of several variables such as reaction temperature, partial pressure of reactants, residence time, loading of the catalysts, and pretreatment temperature, on the conversion and product distribution were observed. The kinetics also has been studied. The conversion and yield of formaledehyde show maximum values at a loading of 20 wt%. The apparent reaction order of methane conversion is ca. 1.0 with respect to $CH_4$ and ca. 0.4 with respect to $N_2O$. In addition, the apparent activation energy is 30.78 kcal/mole. The addition of small quantities methane whereas water introduced to the reactant decreased the activity of catalyst under present study.

The perspectives of customers and providers as for the services have the same objective; however, perspectives and objective are distinctly different. But the existing methodologies have mostly pondered only based on the customer-centric perspective or separately from the perspective of providers. It would be necessary to take these two perspectives as a whole by combining them into one perspective since they not only have differences but also common points. Therefore, in this study suggested the System Journey Map in terms of internal staff based on the customer's task in service. System Journey Map is consists of four parts : a customer journey map, thus the performance of internal staff, internal staff satisfaction evaluation, and finally the performance of internal staff assessment of the senior staff. After releasing a service, with customers and internal staff made a point of contact to identify specific behavioral patterns and whether any part of the problem so that this toolkit gives us an expectation to be a useful map, which is the intangible being placed in service, not just visualize and understand for identifying problems.

To achieve zero-emission, one of the main goals of an eco-industrial park (EIP), it is needed to develop an effective water exchange network. The network includes various subsystems and decision making processes, which make the modeling process extremely complicated. Agent-based modeling was used to simulate water exchange network in an EIP. Firm agents were created based on the behavior pattern of firms, and an agent-based model (ABM) was made with the agents, showing the growth of the exchange network. An existing steel and iron making industrial park was chosen as a case study, and the ABM model shows eco-efficient behavior with a decreased environmental cost. Water reuse network based on the ABM model results in 35% decrease of the fresh water supply and 50% reduction of the wastewater generation in EIP. A case study shows that agent-based model can be a powerful tool in modeling and designing complex eco-industrial parks, especially when a part of the system needs to be changed.

The purpose of this research was to develop an augmented reality-based surgical nursing practice education application. The research proceeded in ADDIE order of analysis, design, development, implementation, and evaluation stages. In the analysis phase, we analyzed the surgical nursing learning needs of the expert group and nursing student group. As a result of the analysis, the demand for surgical instruments was generally high. We selected 51 surgical instruments of the 7 categories most frequently used in the operating room based on the needs, and produced them as AR Book. The augmented reality application was created based on the Unity 3D engine, and the application was built with Android OS so that the target person could use it. Expert assessment of application for augmented reality-based surgical nursing practice education application showed 73.4±4.3 out of 80. This study is significant in the part that first developed a new method of learning tools for surgical instruments. We determined that an augmented reality-based application has reality, portability, accessibility and simplicity.
