Earned Value Management System(EVMS) has been institutionalized as an advanced management technique of construction project lately. And its research has been in the active progress in order to utilize the earned value concept as a project management tool for construction project ordered by both government and private sector. However it is necessary to test and prove the EVMS's adaptability to our construction environment by EVMS's several of operations before its introduction. Project forecasting phase of EVMS is the Estimate at Completion by utilizing earned value data. So, the purpose of this study is to propose EAC evaluation method for evaluation the accuracy of the EAC and encouraging cost realism, and to test for proving the validity of the evaluation methods through hypothesis testing.

정보화 사회로의 급속한 전환으로 인해 고품질 소프트웨어에 대한 관심과 요구가 증대되었다. 따라서 양질의 소프트웨어를 확보하여 시스템의 안정성과 신뢰성을 높이 위해서는 개발활동의 전 단계에서 품질 보증 활동 및 평가가 이루어져야 한다. 개발 초기에는 프로젝트의 특성과 품질요구사항을 철저히 파악하여 품질목표를 설정하고 개발단계에서는 품질목표의 충족여부를 면밀히 점검하여야 한다. 본 논문에서는 소프트웨어 품질 평가의 기준이 되는 ISO 9126을 기반으로 소프트웨어 개발 전 단계에대한 품질특성의 상관관계와 가중치를 설정하고, 정량화된 품질평가 모텔을 제안하여 소프트웨어 개발의 성공에 실질적으로 지원할 수 있는 평가기준 정립 및 표준화를 위한 기초로 활용할 수 있다.

Project managers' leadership in construction projects significantly influence project performance and outcomes. However, due to its conceptual and quantitative nature, leadership is a subject which is difficult to be evaluated or measured despite of the benefits of its measurement. The objective is this paper to apply the LBDQ technique in evaluating project managers' leadership and discuss outcomes through a pilot test.

A construction post evaluation is introduced to provide information that can be used for similar construction projects in the future through the evaluation of the efficiency of a public construction project and the verification of the appropriateness of the project results. However, it is not widely used due to a lack of awareness of the method. For this reason, the aim of this study is to provide a basic frame that can be utilized as a reference for a similar project in the future based on the construction post evaluation. More specifically, a more effective analysis method for the construction post evaluation is proposed and then an exemplary analysis is performed based on the method. The paper analyzes 293 cases stored in construction CALS. Construction cost growth rates of railway projects are tend to be greater than other project types like highway, expressway, and harbour. Then, construction schedule grwoth rates of expressway are greater than others. This is expected to provide useful information for a future project, and serve as a basic frame. Moreover, it is also meaningful that a project can be analyzed from different perspectives through the construction post evaluation.

Public construction projects are implemented by government or public agencies using public resources to enhance the welfare of the people. Therefore, this paper investigates the impact factors for public construction performance. Then, the weights for impact factors are assigned using AHP. The impact factors are categorized into construction policies, project management efforts, and project environment. Further, 16 detail impact factors are listed in each category. The results show that weights are ordered in appropriate budget, reasonable project implementation process, and pre-project planning. These impact factors are related with pre-construction management activities. However, construction related impact like procurement, work difficulty, and construction environment show relatively low weights. The results can be useful to improve construction performance with managing impact factors showed high weights.

As the construction industry gets specialized and complicated gradually, the number of participating organizations increased, and also the necessity of construction management(CM) is getting bigger because construction scale is becoming bigger. However, in spite of the increase in necessity, its activation through performance measurement and evaluation is very insufficient compared with advanced countries. Therefore, a checklist for CM by construction stage using AHP method in the current study is for efficient CM for successful completion of a project by dividing CM affairs by construction stage and checking performance degree by stage. If the CM checklist by construction stage, the final result of the study, is used by all the parties concerned such as construction managers, orders, designers, constructor, etc., it will be possibile to improve work efficiency of project management and produce a final outcome corresponding to the goals of a project.

Using EVMS can probably cause lots of confusion under the different systems and different circumstances of the construction industry between Korea and The United States, because The United States has wide experience in applying to EVMS during several decades but Korea has not. Therefore this research deals with the problem about Performance Indices in forecasting EAC(Estimate at Completion) among the problems of using EVMS. A target index of testing in this research is the Performance Indices used in the research at home and abroad in the past and those is applied to APT projects within the country with statistical method. Through this method, we can catch the tendency and the properties of the Performance Indices for applying to Korea.

Despite the potential implications of Facebook use, there is a distinct lack of empirically derived theory for designing learning environment. This may be because Facebook is a social tool and there has been limited opportunity for exploratory research regarding Facebook based learning. Therefore, the purpose of this study is to investigate learning presence factors affecting learning outcomes in Facebook-based collaborative learning. Forty two college students participated in the Facebook-based collaborative learning activity, and the data from thirty nine were used for step-wise multiple regression analysis. In addition focus group interview was conducted to examine learning presence of Facebook-based collaborative learning. The results reported that cognitive presence predicted significantly learning outcomes, however, social and emotional presence did not predict learning outcomes. The implication of this study and future research were discussed in this research.

The purposes of this dissertation are to identify various factors affecting the outcomes of feasibility analysis and investment decision makings of new IT project plans and empirically analysis the relationships among them. 9 variables which have been drawn from prior studies and industry practices are the amount of the necessary resource such as development budget and time, the expect financial benefits, the degree of alignments between IT projects and the business strategy, the estimated risk, and the investment priority as the dependent variable. Data from 125 IT projects of K bank, the leading commercial bank in Korea, have been collected and Regression Analysis and ANOVA have been performed. As results, 5 out of 8 hypothesis have been accepted partially or totally.
