Background: The emergency planning zone (EPZ) of the city of Busan is divided into the precautionary actions zone (PAZ) and the urgent protective action planning zone; which have a 5-km radius and a 20-km to 21-km radius from the nuclear power plant site, respectively. In this study, we assumed that a severe accident occurred at Shin-Kori nuclear unit 3 and evaluated the dispersion speed of radiological material at each distance at various wind speeds, and estimated the effective dose equivalent and the evacuation time of PAZ residents with the goal of supporting off-site emergency action planning for the nuclear site. Materials and Methods: The total effective dose equivalent, which shows the effect of released radioactive materials on the residents, was evaluated using the RASCAL 4.2 program. In addition, a survey of 1,036 residents was performed using a standardized questionnaire, and the resident evacuation time according to road and distance was analyzed using the VISSIM 6.0 program. Results and Discussion: According to the results obtained using the VISSIM and RASCAL programs, it would take approximately 80 to 252.2 minutes for permanent residents to move out of the PAZ boundary, 40 to 197.2 minutes for students, 60 to 232.2 minutes for the infirm, such as elderly people and those in a nursing home or hospital, and 30 to 182.2 minutes for those temporarily within the area. Consequently, in the event of any delay in the evacuation, it is estimated that the residents would be exposed to up to $10mSv{\cdot}h^{-1}$ of radiation at the Exclusion Area Boundaries (EAB) boundary and $4-6mSv{\cdot}h^{-1}$ at the PAZ boundary. Conclusion: It was shown that the evacuation time for the residents is adequate in light of the time lapse from the initial moment of a severe accident to the radiation release. However, in order to minimize the evacuation time, it is necessary to maintain a system of close collaboration to avoid traffic congestion and spontaneous evacuation attempts.

인터넷의 발달로 인해 조직 안의 마케팅, 광고, 조달, 판매, 서비스 제품 기획 등의 각 부분들간의 전자상거래와 조직간의 전자상거래, 그리고 빠르게 변화하는 기회를 잡기 위해 모인 기업의 컨소시엄의 형태인 가상기업에 대한 관심이 고조되고 있다. 이러한 조직내/조직간의 전자상거래와 가상기업에서 수행되어야 하는 비즈니스 프로세스를 통합, 향상시키기 위한 활동이 웍플로우 시스템이다. 웍플로우 관리 시스템은 기업의 비즈니스 프로세스를 정의하고 수행하며, 이를 추적하고 리엔지리어링한다. 하지만, 비즈니스 프로세스는 오랜 수행 기간과 복잡한 비즈니스 규칙등으로 인해 정확하고 신뢰적으로 수행하는 데에 많은 어려움을 가지며, 따라서 웍플로우 관리시스템은 비즈니스 프로세스의 자동화 및 개선을 위해서 작업 수행의 정확성과 신뢰성을 제공할 수 있어야 한다. 본 논문은 Event-Condition-Action(ECA) 규칙을 사용하여 비즈니스 프로세스를 올바르고 신뢰도 있게 정의ㆍ수행ㆍ분석ㆍ개선할 수 있는 트랜잭션의 지원을 위한 통합적이고 체계적인 프레임워크를 제시하고자 한다. 또한 웍플로우 모델과 그에 수반되는 오류 모델을 함께 제시하고 Petri Net으로 비즈니스 프로세스를 분석하는 방법론을 제시하고자 한다.

This paper is to investigate the micro-behavior of the double-span beams with WUF-W seismic connection under combined axial tension and moment and to propose the rational rotational capacity of it for progressive collapse-resistant analysis and design addressing the stress and strain transfer mechanism. To this end, the behavior of the double-span beams under the column missing event is first investigated using the advanced nonlinear finite element analysis. The characteristics of fracture indices of double-span beams with WUF-W connection under combined axial tension and flexural moment are addressed and then proposed the rational rotational capacity as the basic datum for the progressive collapse-resistant design and analysis. The distribution of fracture indices related to stress and strain for the double-span beams is investigated based on a material and geometric nonlinear finite element analysis. Furthermore, the micro-behavior for earthquake and progressive collapse is explicitly different.

Arbitration is a creature of contract. The parties agree that selective dispute resolution clause provides them with a choice to litigate or arbitrate certain disputes. Under the agreements, the parties had the option in the action. In the event any dispute arises between the parties concerning our representation or payment of our fees and disbursements which cannot be promptly resolved to our mutual satisfaction, you agree that dispute will be submitted to arbitration. Arbitration is a matter of contract and a party cannot be required to submit to arbitration any dispute which he has not agreed so to submit. The selective arbitration agreement has become an accepted method of dispute resolution. However, the trend of dispute settlement has changed. The selective arbitrations clauses are to be construed as broadly as possible, and arbitration will be compelled unless it may be said with positive assurance that arbitration clause is not susceptible of an interpretation that covers the asserted dispute.

A method of optimum design based on reliability for antenna structures is presented in this paper. By constructing the equivalent event, the formula is derived for calculating the reliability of reflector accuracy of antenna under the action of random wind load. The optimal model is developed, in which the cross sectional areas of member are treated as design variables, the structure weight as objective function, the reliability of reflector accuracy and the strength or stability of structural elements as constraints. The improved accelerated convergence gradient algorithm developed by the author is used. The design results show that the method in this paper is feasible and effective.

The progressive collapse analysis of reinforced concrete (RC) moment-frame buildings under extreme loads is discussed from the perspective of modeling issues. A threat-independent approach or the alternate path method forms the basis of the simulations wherein the extreme event is modeled via column removal scenarios. Using a prototype RC frame building, issues and considerations in constitutive modeling of materials, options in modeling the structural elements and specification of gravity loads are discussed with the goal of achieving consistent models that can be used in collapse scenarios involving successive loss of load-bearing columns at the lowest level of the building. The role of the floor slabs in mobilizing catenary action and influencing the progressive collapse response is also highlighted. Finally, an energy-based approach for identifying the proximity to collapse of regular multi-story buildings is proposed.

A major objective of the study is to propose a supervisory control algorithm based on the discrete event dynamic system (DEDS) model and apply it to the automation of nuclear operations. The study is motivated by the suitability of the DEDS model for simulation of man-made control action and the potential of the DEDS based supervisory control algorithm for enhanced licensibility, when implemented in nuclear plants, through design transparency due to strong analytic backgrounds. The DEDS model can analytically show the robust stability of the proposed supervisory controller providing design transpareney for enhanced licensibility when implemented in nuclear operations.

A workflow management system is a software system to assist designing processes, controlling and managing the execution of the designed processes. One emerging trend in many recent information systems is the provision of process management functions. In this paper, we propose a method of designing processes for automatic process execution directly from process modeling. First of all, the concept of block is presented which is to define a nested process model. A block is the minimum unit that can specify the relationships of process components, i.e., tasks. A general process can be defined by a combination of the blocks defined in this paper. An algorithm is developed to transform a general flat process model into a nested model. We identify basic types of blocks and build ECA (Event-Condition-Action) rules for each of the basic types. This allows us to automate the execution of the process model by using the active features of active databases.
