The technology of virtual environments has been developed with better-quality appearance on a computer display in mind, but without consideration for objects' precise measurements in physical units. With the increased application of computer graphics in a variety of areas, there is a need for precise measurement functionality in addition to visualization. This paper describes the definition of physical properties using measurement units for X3D based virtual objects, to provide their precise physical information in virtual environments. To this end, we have included the physical property node in the X3D specification. The physical measurement units, such as length, mass, time, temperature, etc., are based on SI units (International System of Units).

Recently, the disaster situation has been diversified and compounded worldwide as well as in Korea. And the damage scale of each disasters have increased, and following economic loss is also increasing immensely. In Korea, especially the out break frequency of large-scale disasters has increased. Disasters caused by earthquakes are also very likely to occur. When a major accident such as Mauna resort collapse accident, Ferry sewol sinking accident occurred, systematic emergency medical care at the site at the time of disaster occurred in order to operate an emergency medical facility corresponding to the site, which is not systematic. The need for this service is urgent. If highly reliable emergency medical system function at appropriate times in the disaster site, secondary damage can be reduced and the whole situation would be back to normal shortly. Therefore, it is necessary to provide an emergency medical system capable of quickly and safely responding to disaster sites in relation to various damage scale. For the purpose, thorough analysis on mobile medical units of inside and outside the country was accomplished. As a result, Mobile Medical Unit of outside the country are trailer type, tent type, container type etc. At home, these types have been studied and will be proposed early next year as a temporary solution. Here we introduce suitable types for our country.

This study presented a new NOS model through the following suggestions to apply the construction work planing and management to NOS(Network Operating System). First, This study presented CIMS(construction information classification system) reflected the characteristics of facility classification - functional component classification - functional component classification - work classification - resource classification. Based on this system. this study presented how to establish PMMB(performance measurement management baseline) with proposed master target equation which analyzed the trend of performance measurement management baseline and proposed work target equation which analyzed the execution results. Finally, this study presented NOS model that can be applied to fixed price method and cost plus fee method through the theoretical verification of executive performance analysis method.

Green building certification is being implemented in various countries around the world for the purpose of securing sustainability and reducing energy use and carbon emissions. Korea has been implementing G-SEED, a green building certification, for buildings since 2002, but in foreign countries, the evaluation target has been expanded from buildings to neighborhood units, cities, and infrastructure. Therefore, the purpose of this study was to establish Korean green building certification system in terms of neighborhood scale. In order to make Korean certification scheme for neighborhood communities, three major international certification systems (BREEAM Communities, LEED-ND, and CASBEE-UD) were compared. Comparison was executed about definitions and goals, certification system and range, certification categories, and regulation relationship by literature review. Based on the results, the evaluation system proposal including the scope, subjects, and items for green building certification in Korea was proposed.

The purpose of this study is to provide a suggestion to improve speciality and job performance of social work case management using importance-performance-analysis(IPA). A quantitative research design was used and data were collected from 209 social workers who are in charge of case manager job at Ulsan metropolitan area. Study participants were asked the recognition of importance-job competence and need for supervision-experience of social work case management job description on the NCS(9 competency units, 33 competency units). Descriptive analysis and IPA were performed. This study found the need for intensified job competence of 'building external operating systems' and 'development of resource linkage systems'. Also, it is necessary to provide intensive supervision for 'building an external and internal operating system.' Based on the results, future direction of intensified job performance for socla work case management was discussed.

It is required that information sharing and integrated management between roads and underground facilities because there are so many possibilities to happen unexpected accidents. But if there are road excavation work happened, work agency should ask fer other facility information to the facility management company. In the case of local government, it is increasing that the needs for the development of roads and underground facilities management system and information sharing because digital map generation(1/1,000 scale) completed. In this study, as a way of integrated management and information sharing between roads and underground facilities, centralized system based on internet web technique and decentralized system based on closed network technique between the local government are considered. And for the development of information sharing system, action plan and considering points are proposed.

각 관공서나 공공기관에서 발생되는 각종 공사현황정보와 기술정보를 시설물 전체 수명주기동안 제대로 활용하기 위해서는 시설공사관리 업무를 전자처리체계로 전환하는 것이 시급하며, 사업계획에서 준공까지 일련의 과정에서 발생하는 문서들의 보관이 비체계적이므로 이를 잘 보관하고 재 사용하기 위한 관리체계가 필요하다. 따라서 본 연구는 공공건설분야를 담당하고 있는 지방국토관리청을 대상으로 사업단위별로 업무를 7가지로 세분화하고. 그 중에서도 핵심부분인 공공건설사업에 대한 체계적이고 효과적인 관리체계를 유지할 수 있는 웹 기반의 공사현황 정보시스템을 제안한다.

Computational science is at an early stage and is not yet fully active, and the high-performance computing required in the field of computational science is at present a special subject of parallel and distributed computing in computer science. Additionally, there are too few education courses which teach high-performance computing from basic to advanced levels. In this study, we derive the knowledge units needed to learn high-performance computing, an important research tool in computational science. Using ACM the Computer Science Curricula 2013 (CS2013), we examine the validity and reliability of 89 knowledge units and eleven knowledge units with high validity and reliability, after which nine core knowledge units and two optional knowledge units are proposed. The eleven proposed knowledge units are expected to contribute to the development of the high-performance computing curriculum necessary to teach computational science.

본 연구는 이산 사건 시스템 형식론(DEVS: Discrete Event System Specification)을 이용한 가상전장 모델링 및 시뮬레이션 방법론을 제안한다. 기존 군체계에 관련된 모델링 기술은 물리적 모델링, 비쥬얼 모델링, 또는 개념적 모델링 등 개별 기능중심의 단편적 플랫폼 모델링에 그치고 있으며, 무기체계 분석 시뮬레이션도 개별 단위체 중심으로 평가되어져서, 다양하고 종합적인 그리고 상호운영성과 재사용성 등을 고려한 통합 모델링 및 시뮬레이션 환경을 제공하지 못하는 단점을 갖는다. 따라서 본 논문에서는 개별 전투병력에서부터 첨단 무기체계에 이르는 다양한 전장 요소들을 계층 구조적으로 통합함으로써 장에서 발생될 수 있는 개별 전투병력의 미시적 행동 특성뿐 아니라 분대/중대/대대/사단급 단위의 거시적 전략/전술에 대한 묘사까지도 가능한 가상전장 모델링 및 시뮬레이션 환경을 제안한다. 제안된 방법론은 분대 단위의 가상 전장 환경에 대한 사례연구를 통해 검증하였으며, 향후 연구로는 대단위 가상전장에 대한 묘사를 위한 HLA 분산 시뮬레이션 기술의 적용에 대한 연구가 필요할 것이다.
