기존의 객체 분석 메소드에서는 사용자 이해 수준에서 요구사항이 명세되지 않으며 또한 요구사항이 만족되는가를 검증하기도 어렵다. 요구사항이 잘 반영된 좋은 품질의 분석 모델을 개발하기 위해서는 사용자 수준에서 이해될 수 있는 요구사항을 명세해야 하며, 이를 기반으로 클래스를 식별하는 작업이 필요하다. 이를 개선하기 위해 정보 구조 모델링 기반 분석 클래스 식별 절차를 제안하였다. 비교 연구결과, 본 논문에서 제안한 절차는 정적 모델 명세에 치중된 경향은 있으나, 제품의 반복성이 우수하며, 품질 부-부특성들을 평가하는 것이 가능하여, 좋은 품질의 분석 모델을 개발할 수 있다.

Early planning phase of private development project is an important part in mercy of failure and success of all project. Hut reliability of analysis result existing planning phase in not high to the importance. So we analyzed a basic problem point through case study and research data analysis of planning phase in private development project. After this, there is a cause in no establishment of systemic model about work processing and method of planning phase. We would like to suggest the solution through establishment of planning phase analysis processing and risk management model. We think that suggested analysis method increase the credibility of analysis result. With this, we anticipate we suggest the guideline in project process phase and that assist the effective accomplishment of project.

BIM can be utilized variously in construction management(CM) in the respect that it helps to manage comprehensively the construction information and make reliable decisions, but the adoption of BIM is insufficient in the CM area. The purpose of this study is to develop work process models and their guides in order to utilize BIM effectively in CM work at construction stage. This study defined BIM functions as 'BIM converting design', 'Model review', 'Data extraction', 'Automatic estimate', '4D simulation', 'Drawing creation', 'Engineering sector linkage analysis' through literature search, and generated CM works applicable to BIM by analyzing the CM work and process. This study developed BIM-based CM work process models by reconstructing the existing work process in connection with BIM function through an analysis on the relationship between BIM function and CM work, and reconstructing the role of each project participants. In order to improve the usefulness of the developed models, guides that described the BIM works of project participants were prepared through interviews and case studies. To validate the utilization of the models, a comparative analysis on the BIM process of precedent studies was also made and a survey was conducted on experts. This study can contribute to increasing the utilization of BIM in the CM area and can be helpful for CM companies to develop an in-house BIM guide. In the future, it will be necessary to make an assessment on the models from a business perspective through case applications and constantly update BIM-based CM work process model in consideration of the expansion of CM work due to the application of BIM.

The purpose of this study is to suggest a systematic procedural model for selecting competent project promoter. The proposed model was made by comparing domestic regulations and procedures with foreign nations', and through interviews with experts and literatures survey. The summaries of this paper are as follows. The current promoter selection procedure was evaluated by reviewing relevant papers, regulations and existing model. Some obstructions which hinder PPI project activation were identified, those are inadequacy of promoter qualification and negotiation process, lack of communication between parties, etc. Some alternatives which remove major obstructions are embodied in the model. The suggested model is comprised of PQ(prequalification), two phased evaluation for the technical proposals which include alternate, communication meeting, etc. To manage the overall procedure well, an involvement of professional "project promoter selection team" would be highly recommended. They will participate in each evaluation stage with full activities, and provide government with some technical materials for selecting promoter as coordinator.

원전 운전에는 그 수행에 필요한 많은 직무가 있고, 직무가 어떤 것인가에 의해 운전원에게 할당되는 직무와 기계 즉, 자동화된 설비에 할당되는 직무로 분류된다. 차세대 원전에 적용할 전자식 절차서에서는 단순, 반복적인 직무는 자동화 설비에, 인간의 판단과 같은 고도의 사고를 요구하는 직무는 운전원에게 할당하여, 인지해야 하는 정보의 수가 많고, 해당 운전상황을 정확하게 판단해야 하는 비정상 및 비상 운전시 운전원의 작업부담 (Work-load) 를 줄이고자 하는 방향으로 개발이 진행되고 있다. 본 논문에서는 기존 원전에서 적용하고 있는 절차서의 수행과정을 절차서 수행에 필요한 직무가 어떤 것들이며, 운전원의 어떤 행위에 의해 수행되는지의 관점에서 이들을 정성적으로 분석, 전자식 절차서 시스템에 적용할 절차서 수행 모델을 개발하고, 아울러 전자식 절차서 인간-기계 연계 화면에서 제공하고자 하는 주요 운전변수들의 표시형태를 확인, 구현해 보았다.

The purpose of this paper is primarily to examine models of collective decision-formation and decision-making. The goal is to propose a model of decision-formation and decision-making that is appropriate for a democratic society. Habermas distinguishes these models of decision-formation and decision-making by liberal, republican, and deliberative political models according to their justification types. Axel Honneth, on the other hand, is divided into three models of liberalism, proceduralism, and republicanism. I want to divide the model of possible decision-making in democratic society into three, that is, the model based on force, the model based on procedure, and the republican model. This distinction will identify the characteristics of each decision-making model and this confirmation will help us find the best decision-making model for a democratic society. In the end, I will combine the republican model with the procedural model. For this synthesis, I will also propose three conditions in modern society. I will argue that the three conditions of collective intelligence, active freedom, and horizontal networks are necessary.

The development of a Pay Adjustment (PA) procedure for implementing Performance-related Specifications (PRS) is known to be a difficult task faced by most State Highway Agencies (SHAs) due to the difficulty in such areas as selecting pay factor items, modeling the relationship between stochastic variability of pay factor items and pavement performance, and determining an overall lot pay adjustment. This led to the need for an effective way of developing a scientific pay adjustment procedure by incorporating Life Cycle Cost Analysis (LCCA) embedded Monte Carlo approach. In this work, we propose a prototype system to determine a PA specifically using the data in the pavement management information systems at Wisconsin Department of Transportation (WisDOT) as an exemplary to other SHAs. It is believed that the PRS methodology demonstrated in this study can be used in real projects by incorporating the more accurate and reliable performance prediction models and LCC model.

This study was conducted to review the adequacy and applicability of the safety certification system for educational facilities which was implemented in 2021 and to derive possible improvements to the existing certification system. This study analyzed the existing certification system, examined similar systems from abroad, conducted interviews with certification experts, and presented the proposed improved system to experts for review and advice. The proposed model replaced the current certification process with three stages of follow-up management. This allows for problems that may occur in the evaluation process and the composition of evaluators to be prevented by applying a feedback system. In the review stage of the newly proposed certification system, certification experts recommended specifying the detailed standards of certification performance such as criteria for selecting examiners and arbitrators. They concluded that there were no fatal flaws in the overall structure of the evaluation system. According to the results of this review, the proposed evaluation system was proven to be an effective improvement to the existing system.

최근 소프트웨어 산업에서는 개발 기간의 지연, 비용 증대와 같은 위험관리를 하기 위한 방법으로, SPI 전략이 활발히 진행되고 있다. 사실표준인 CMM이나 국제표준인 SPICE 등이 SPI의 참조적인 모델로 사용된다. 그러나 이들 모델은 특정환경을 가진 소프트웨어 개발 조직에 대한 품질 개선을 위해서 필요한 구체적인 개선 절차와 방법을 기술하고있지 않다. 특히 SPI를 위해서 SPA가 선행되는 경우가 많은데, 효율적인 SPA를 위해서는 심사절차에 대한 정형화가 필요하며 이를 통하여 심사의 일관성을 유지할 수가 있다. 본 논문에서는 심사의 정형화를 위해 SPA의 각 단계들을 UML을 사용하여 표현하고, 모델의 신뢰성을 ISO/IEC 9126의 6가지 품질 특성의 테두리 안에서 검증하고자 한다. 또한 결함들(Defect)간에 연관성을 분석하여, SPA의 등급평가 절차에서 사용되도록 제안한다.

객체지향 방법의 초기 단계인 객체지향 분석은, 문제 기술서에서 사용자 요구 사항을 실 세계의 개념과 도메인 지식을 통하여 객체 관점에서 모델링하고, 객체 지향 요구 명세를 생성하는 절차이다. 기존에 제안된 객체 모델링 방법론에서 분석 단계의 정적 모델링은 시멘틱 모델 등의 풍부한 시멘틱을 제공하여 모델과 모델링의 많은 부분들을 정형화할 수 있었다. 그러나 대부분의 방법론들의 분석과정은 동적 모델의 정형화가 미흡하다. 본 논문에서는 시스템의 정적인 구조를 검증할 수 있는 정보 트리 모델에 동적인 행위 정보를 포함하도록 확장하고, 검증 절차를 제시함으로써 시스템의 동적 행위를 검증할 수 있게 하였다. 또한, 객체 지향 요구 명세의 동적인 행위에 대한 검증은 확장 정보트리를 사용하여 use case와 시나리오를 추적하면서 검증한다.
