Some regions and states, such as Wyoming, have harsh weather conditions, forcing most transportation projects to be completed under tight schedules. However, construction projects are not only delayed by weather conditions, but also delayed by other factors such as contractor's competency, resource availability, coordination issues, and safety. Also, the construction method, geographical location of the projects, and inability to follow baseline schedules accurately due to the contractor's resource allocation are also reasons for the delay. This paper discusses the main reasons for the delay in the public transportation projects based on Daily Work Reports (DWRs) from five different transportation projects of the last three years in Wyoming. This paper focuses on the inconsistencies of the contractor's schedules to complete the project according to the baseline schedule. First, the authors collected DWRs and baseline schedules from the Wyoming Department of Transportation (WYDOT). Second, the DWR data are compared against the baseline schedules to determine the reasons for delaying their significance. Finally, the paper presents the recommendations to mitigate the effects of delays on public transportation projects as well as to improve the documentation process of DWR data.

In construction projects, it is very important to evaluate the performance of works in comparison with the cost and schedule plans. So, on the first of July, 2000, the Ministry of Construction and Transportation announced the EVMS will be applied in public sector soon. However there are still many arguments about how to establish the Performance Measurement Baseline(PMB) and how to evaluate the progress with accuracy. And many people confuse the meaning of EVMS with that of cost and schedule management. So, the purpose of this research is to propose the new useful methods to set up the PMB and to assess the exact progress in consideration of cost, schedule, and float time for successful implementation of EVMS.

In the current construction industry, difficulty arises in creating an adequate baseline schedule to establish a fundamental plan for construction. This presentation will present the research findings which investigated industry-recognized schedule metrics that aid in the successful implementation of said schedule. Industry organizations (Association for the Advancement of Cost Engineering, the Government Accountability Office, the Project Management Institute, and local city, state, and county government offices) provide standardized guidelines with specific metrics requirements to ensure successful implementation. However, most of those metrics are substantiated or validated in their effectiveness. The study examined the impact between these industry-recognized critical metrics and three distinct scheduling characteristics: Project Type, Project Duration, and Project Density (number of activities within a schedule). The research results showed that, among the 12 various schedules evaluated in parallel with 20 industry-recognized critical metrics, seven metrics substantially demonstrate a significant impact on a project schedule's success. Furthermore, six of the seven metrics directly correlate to at least one of the three scheduling characteristics outlined. As a result, this research has established more predictable outcomes based on impacts between three distinct project characteristics and 20 of the most discussed/researched critical scheduling metrics in the field. This allows management teams to have more confidence in establishing critical milestones and accurate turnover dates from the start of the project through its final completion.

The PMB(performance measurement baseline) is the total time-phased budget plan against which program performance is measured. Additionally it is the schedule for expenditure of the resources allocated to accomplish program scope and schedule objectives, and is formed by the budget assigned. In this paper, we suggest an improvement of the R & D(research and development) program for defense acquisition by using the PMB and an application of the IBR(integrated baseline review) to review the PMB for project manager of the defense agency.

프로젝트 관리 성숙도(Project Management Maturity Model)란 프로젝트 관리 관련 업무 성숙도를 측정하는 것으로, 프로젝트 성공을 위해 관련 있는 업무가 어느 정도 수준으로 진행되고 있는가를 평가하는 목적으로 주로 사용된다. 본 논문에서는 프로젝트 관리 성숙도를 활용하여 프로젝트 관리 성숙도가 범위, 일정, 그리고 원가에 미치는 영향을 연구 하였다. 연구 결과로 프로젝트 관리 성숙도가 낮으면 범위 변경률이 커지고, 일정이 지연되며, 비용 또한 초과되는 것으로 나타났다. 본 연구의 성과를 토대로 기업이 프로젝트 관리 성숙도 향상을 위해 투자와 노력을 해야 한다는 것을 알 수 있다.

The risk in the constructions projects is extremely diverse because there are too many indefinite factors. Therefore, Performance Measurement Baseline(PMB) is needed regularly during the construction process. However, nowdays, the PMB in the constructions projects is for contractors' PMB and Performance Management(PM). Clients have a lot of difficulties to control and manage the projects. Therefore, this paper classifies schedule and cost data of the public apartments houses which is a actual cases into types and then conducts regression analysis and deduces a regression. In addition to this paper establishes the Work Breakdown Structure(WBS) and suggests the PMB for the clients through using that.

Purpose: Sublingual immunotherapy is currently promoted by various companies, with administration schedules variable in the different products even though almost all are standardized immunologically. So, this study was planned to examine the efficacy of simple nondaily dosing of sublingual immunotherapy instead of the widely used daily schedule. Materials and Methods: Fifty-two patients with allergic rhinitis and bronchial asthma were enrolled. Sublingual immunotherapy (manufactured at the allergen immunotherapy preparation unit at Mansoura University) was given in suitable bottles with a dropper mechanism that permits comfortable dosing under the tongue. The physician recommended that the patient put the drops under his/her tongue and leave the drops beneath the tongue for 2 minutes before swallowing. This was repeated every 3 days, with the drop number and concentration gradually rising. Results: After 2 months of follow-up, 65.8% responded partially to the symptom score and 26.3% responded completely to the medication score. There was a significant decline in the symptom and medication scores from the baseline scores (p<0.0001). After 4 months of follow-up, 95.8% responded partially to symptom scores and no one has not responded; 54.2% responded completely to medication scores; and 81% of studied patients had no side effects. However, the most frequent side effect was a sore throat. Conclusion: Our nondaily schedule of sublingual immunotherapy is tolerable, safe, and effective in patients with allergic rhinitis and bronchial asthma.

This research has been Initiated to provide an effective management tool for budget control of the public projects using EVMS. Barriers to implementing the tool for the domestic public projects are identified : no PMB (Performance Measurement Baseline) for budget control, management by BOQ(bill of quantity), no systematic planning and control. To eliminate these barriers, an integrated cost and schedule management process model using EVMS is proposed. This model is composed of six sub processes : organizing, scheduling, budget allocating, establishing PMB, managerial analysis, change incorporation.

The purpose of the research is to propose an integrated project planning process and its implementation method. Although there is increasing interest in the application of the Earned Value Management(EVM) method in the project management area, the progress and maturity of the technical performance have not been included in assessing the Earned Value. The main concept of the planning process is to use cost, schedule, as well as the technical performance in the assessment of the Earned Value Management for Military R&D project management practices. The resulting process can enhance the efficiency of the project work by eliminating the currently duplicated activities between traditional project planning process and the newly implemented Earned Value Management process and by shortening the early planning process duration of projects adopting EVM practices.

Aim: We aimed to examine the cross-sectional and longitudinal associations between sleep and work-related impaired cognitive and emotional functioning in police employees. Methods: This study included 410 participants (52% men) employed in a police district in Norway at baseline, of which 50% also participated in the study at 6 months later follow-up. The questionnaires included items measuring work schedule, sleep length, insomnia, as well as impaired cognitive and emotional functioning at work. Results: The results showed that insomnia was related to impaired work-related emotional functioning measured at baseline, and to impaired cognitive functioning measured at both baseline and follow-up. Sleep length and rotating shift work were not associated with future decline in cognitive or emotional functioning. Conclusion: Our study indicates that the relationship between insomnia and emotional functioning at work may be transient, whereas insomnia can be related to both immediate and future impaired cognitive functioning. Replication of the findings in larger samples is advised. The findings call for an emphasis on the prevention and treatment of sleep problems among police employees as a mean of maintaining and improving cognitive and emotional functioning at work, and thereby reducing the risk for impaired performance and negative health and safety outcomes.
