The purpose of this research was to provide the information of mandatory regulation for Korean sports facilities and the preliminary data for building sport safety management manual through sports facilities abroad and system status. Futhermore, based on the information of sports facilities safety management, this research performed the benchmarking of each country sports facilities safety management system. As a result, in the U.S, Department of Homeland Security(DHS) leads effort to achieve a safe, secure, and resilient homeland. In Germany, law & regulations, sports facilities safety guideline and expert extension have been reviewed. Germany is more realistic and practical than other countries. In Australia, Major Hazard Facilities(MHF) is responsible for eliminating the risk of a major incident. Emergency Management System(EMS) should spontaneously respond when the alarm is raised as early detection and intervention are vital to ensuring that a small incident does not escalate to become a major disaster.

As the knowledge-based society has been constructed, the size of work process that has to be done grows bigger and the amount of the information that has to be analyzed increases. So each company is trying to construct more conformable process models in business model. In order to support the process construction of companies practically, in this paper tools of Six Sigma is applied to process definition and tools of PSP is applied schedule management. And to use the proposed tools efficiently, the procedure of process definition and schedule management are suggested. The goal of the proposed method is to achieve the process aim within the Time-To-Market by applying the process management of organizations and persons. And the goal of individuals is to improve personal process with the collected data.

목적 : 방사선치료기술이 날로 발전함에 따라 방사선치료계획시스템에 대한 주기적인 정도관리의 필요성은 증대하고 있으나, 국내 실정에 적합한 표준화된 정도관리절차서가 없는 실정이다. 따라서 본 연구에서는 방사선치료계획용 시스템에 대한 정도관리용 고체팬톰을 제작하여 주기적인 정도관리 활용 및 절차서를 제시하고자 한다. 대상 및 방법 : 체윤곽 보정을 위한 삼각기둥 모형 (30cm$\times$30cm$\times$5cm, 30cm$\times$15cm$\times$5$\times$) 및 정형ㆍ부정형, 불균질 측정이 가능한 물등가고체팬톰을 제작하였고, 컴퓨터단층촬영(AcQsim)을 통해 영상을 얻었으며, RTPS(AcQplan)에 입력하여 영상 내 기준점에서의 선량값을 계산하였다. RTPS를 통해 계산된 값의 평가를 위해 동일한 조건하에서 각 기준점에 대한 실제 측정을 이온함을 이용하여 측정하였다. 평가 항목으로는 정방형 조사면, 부정형 조사면, 쐐기 조사면, 불균질 물질 보정, 사방향 조사 등에 대해서 알고리즘별로 수행하였다. 결과 : RTPS를 이용하여 계산된 값과 실제 측정한 값을 비교하여 RTPS의 정확성을 평가한 결과로 합성의 불확도 허용 기준 (3%), 선속 중심축 상에서의 허용 기준 (2%) 등, 선진 각국 및 각 학회에서 권고하고 있는 허용 범위 내에서 잘 일치하였다. 결론 : RTPS는 측정된 심부선량과 선량분포 등 물리적인 인자에 의존하는 제한성이 있고, 실제로 선량계산 알고리즘과 기하학적 변화에 따라 계산값과 측정값 간에 차이가 발생할 수 있었다. 실제 인체의 체윤곽 불균일성과 불균질성을 모사한 팬톰을 제작하여 이용함으로써 다양한 RTPS간의 비교를 통한 치료 선량의 정확성을 평가하고, 방사선 치료의 원활하고 정확한 수행을 위해 실용적이고, 보편적인 치료계획 시스템의 정도관리 방법과 절차서를 수립하는데에 유용할 것으로 사료된다.

The road user cost in indirect costs as well as direct costs such as the inspection/ diagnosis cost and the repair/reinforcement cost should be considered as one of the important items in the life-cycle cost-effective design and maintenance of the bridges. To estimate the road user cost, this paper formulates the road user cost as a sum of the user delay cost and the vehicle operating cost considering the detour effect. A numerical traffic simulation and a regression analysis are performed to develop a regression model due to a time delay. The proposed regression model is applied to the generation of the maintenance strategy based on the life-cycle cost and performance, and its effectiveness and applicability is investigated. The road user cost has a great influence on establishing the maintenance strategy, and the proposed regression model could be successfully utilized to estimate the road user cost of a bridge.

The mixed-use development project like urban regeneration project has been enforced with long period and participation of various stakeholders. For this character, lots of risk could be occurred during the process of project and the project's success or failure depends on the risk management. So the process of identifying and responding to risks in urban regeneration projects should be followed systemically. The risk identification phase is the first step to identify risk factors and define risk's character. One of the risk identification methods, the checklist, is the most practical and well-known one. This study suggests the check list that devide risks classified by stakeholders through analizing tasks of stakeholders and drawing risks. This kind of checklist which handles risk factors classified by stakeholders is an easy tool to identify risks and expected to be effective to find risks for various stakeholders and themselves in the urban regeneration projects.

This paper illustrates some practical geographic information system (GIS) applications for aiding fishery managers and coastal area planners in analysing the likely control scheme of coastal farming areas, and in providing a flexible framework for decision making on fishery development and zoning issues. The effective management of marine farming operation is vitally important since it can greatly influence economic availability by determining capital outlay and by affecting running costs, rates of productions and mortality factors. GIS has been widely adopted elsewhere as a potent management tool in both the private and public sectors. GIS is now being extensively adopted in marine-associated activities. Here, we have used GeoMania v2.5 GIS software and its 3D Analyst extension module to visualize marine farming areas data that were collected around the Jinhae bay.

Internet of Thing (IoT) computing is an environment where various devices with sensors and actuators are connect, and interact together to acquire contexts and provide useful services. With the advances of IoT technologies, its usability becomes an in important issue. However, there exist various types of faults in IoT computing which are not conventionally addressed in software research community. Providing reliable IoT services is challenging. In this paper, we present a hierarchy of IoT faults and analyze causes and symptoms of the faults. Based on the analysis, we define effective methods for managing IoT faults. We believe that our proposed framework for managing IoT faults can be utilized in reducing the development cost of IoT applications and enhancing the quality of the applications.

Component-based development(CBD) has acquired a substantial acceptance in both academia and industry as an effective inter-organizational reuse technology. A component framework in product line engineering(PLE) which consists of related components, connectors and their semantics has a greater potential for reusability than components. In frameworks, components are glued with association, dependency and connections. Problems occur like affecting the implementation code of components when they are glued and replaced because the association and dependency relationships between COTS components which are acquired for application development do not match exactly. Especially, a connector may not only connect related components, but also mate partially-matched COTS components fit together. However, little has been studied to date about connectors that can be used practically. In this paper, we present a meta-model for connectors and show how a connector can be designed and implemented in practice. We propose five main patterns of connectors. Proposed major patterns Provide design guidelines for practical and efficient connector configuration based on component framework. And also, applying techniques and applied case studies of the major patterns show greatly increased applicability and reusability of the component without component modification.

This study seeks to find the sociocultural value which influences the man image and make-up in media. It helps to gain the effective data that suggest the application of male make-up in promoting development of market. The man emphasizes the practical value which is the technical and instrumental value to express the man image rationally, aesthetic value to pursue aesthetic purely and symbolic value which is a volitional and intentional value experienced in the history and society to express preferring man images as the society is changed. As analysing the man image based on sociocultural value, the practical value of men's make-up is to maximize the utility vale in order to deliver a clear image considering their activity range, environment, and situation. Second, the aesthetical value of men's make-up is to emphasize femininity through women's make-up technic. Third, the symbolic value of men's make-up is to deliver a concept or intentionally create an image by maximizing overall characteristic image. It will be hopefully valuable as a basic data for developing make-up products and setting trend for men as well as for future studies.
