본 연구는 도로안전개선사업의 공간적범위 (지점단위/구간단위)에 따른 도로안전시설물의 효과도 비교를 목적으로 한다. 분석자료는 전라북도 지역 국도를 대상으로 사고잦은지점개선사업과 국도17호선 구간안전개선사업 시행도로에 대한 사전 사후 사고자료와 도로 교통특성자료를 이용하였다 경험적베이즈기법(Empirical Bayes ; EB)을 이용한 시설물별 효과도 산정모형을 구축하고, 비교를 위해서는 승산비 (Odds Ratio)를 이용하여 상대효과도 산정기법을 제시하였다. 분석결과 구간사업에서 설치한 안전시설물이 지점단위 개선사업보다 상대적으로 $7.09%{\sim}77.27%$ 안전성을 개선시키는 것으로 나타났다. 사업의 공간적 범위에 상관없이 구간특성을 가지는 시설물인 중앙분리대와 가드레일은 상대효과도가 크지 않게 나타났으나, 대표적인 지점설치 시설물인 갈매기표지나 미끄럼방지포장 등은 구간사업에서 그 상대효과도가 매우 크게 나타나 향후 시설물 설치시 구간측면에서 고려가 필요함을 알 수 있었다. 이와 같은 연구결과를 토대로 보았을 때 향후 안전시설물 설치와 같은 도로안전개선사업은 구간단위 사업이 확대되어야 할 것으로 보인다.

Objectives : The purpose of this study was to evaluate and compare the cost-effectiveness of Eastern, Western, and collaborative treatments and suggest a cost-effective approach for patients with frozen shoulder pain. Methods : Using the data of fifty-two patients, treatment effectiveness was measured by CSA, SPABI, and ROM scales and changes from the baseline score were evaluated. Data source for cost estimation was based on the national health insurance (NHI) payment system. Because the price in NHI was differentiated by health care institutions, five collaborative types were considered in assessing costs. Cost-effective ratios were computed for economic evaluation. Results : Compared with Eastern treatment, collaborative and Western treatments showed better effects on CSA scale after 4 weeks' treatment. The collaborative approach was also the most effective treatment on SPADI and ROM scales. The direct cost per patient receiving Eastern treatment was less than other treatments. In general, collaborative treatment dominated Eastern and Western treatments in cost-effectiveness an analysis. However, the cost-effectiveness ratio of Eastern treatment resulted in \9,000 compared to \29,000 of collaborative treatment on SPADI. Four different indicators of ROM scales resulted in different approaches as the cost-effective treatment. Conclusions : Considering cost-effectiveness ratios, collaborative treatment was the best treatment on CSh and SPADI scales after 4 weeks' treatment. As for ROM scales, the recommended alternatives were Eastern treatment for patients with abduction and adduction disabilities, Western treatment for those with flexion disability, and collaborative approach fir those with extension disabiliry.

Purpose: In the Korean railway infrastructure process, contractors and operators are involved at a later stage, which results in significant inefficiency. This study examines the benefits of early stakeholder involvement in Korean railway infrastructure projects and provides practical guidelines. Design, data and methodology: Literatures and foreign cases are analyzed. Building on the new product development model, we derive propositions explaining the relationship between early stakeholder involvement and the performance of Korean railway infrastructure project. Results: Major propositions include that early involvement of contractor has a positive effect on the project performance by shortening the infrastructure construction period and that early involvement of railway operator has a positive effect on the project performance by improving the effectiveness of railway infrastructure. Four requirements for the success of early stakeholder involvement are addressed. Conclusions: This study suggests that early stakeholder involvement shortens the construction period and improves railway infrastructure effectiveness. Academic contribution is to present the framework on railway infrastructure projects as holistic interactions among stakeholders. Practical contribution is to provide railway policy makers and other business practitioners with policy guidelines to improve railway infrastructure project process and to recommend an open access to relevant data.

Based on the characteristics of 'Korean electric power industry R&D programs', this study proposes a new performance evaluation framework where electric power industry related R&D projects are scrutinized. The abovementioned R&D programs have their own goals and especially they emphasize the effectiveness as well as the efficiency of each subordinate R&D project. Hence, in this framework, a performance evaluation procedure is established and then a mathematical model is developed according to the procedure. The model calculates performance evaluation indices for a set of R&D projects integrating the effectiveness with the efficiency of each R&D project. In a case study with an empirical dataset, statistical significance is tested on the integrated performance evaluation indices of R&D projects regarding organizational types and program categories considered.

Aging populations and the increasing mental health issues among them have set a new challenge for the international community, governments, and people. Given this, society's role is very important, and involving the local community in resolving the problems can play a pivotal role. The current study presented the systematic review of the financing mechanism and cost-effectiveness of the "social prescribing" (SP) project in the United Kingdom and how SP can be adapted for other settings. The data showed comparatively low running costs and the overall effectiveness of SP projects. The running cost of SP projects varied between £54,525 and £1.1 million. The cost-effectiveness of the projects reported as 12% and the return of investment was about 50% depending on the type of analysis and the activities implemented. This type of intervention can be one of the options that support solving the issues of aging populations and their accompanying mental disorders.

Construction projects have frequently exceeded their schedule despite reliable estimates at the start of a project. This problem was attributed to unpredictable causes at the beginning and to shortage of proper tools to accurately predict project completion date. To supplement this difficulty, project managers need a comprehensive system that can be employed to monitor the progress of an ongoing project and to evaluate potential delay for achieving the goal on time. This paper proposed a progressive-based expert system for quantitative assessments of project delay at the early stages of the execution. Furthermore, the system is used to inspect the change of the uncertainty on completion date and its magnitude. The proposed expert system is helpful for furnishing project managers a warning signal as a project is going behind schedule and for tracking the changed uncertainty at a desired confidence level. The main objectives of this paper are to offer a new system to overcome the difficulties of conventional forecasting tools and to apply a construction project into the system to illustrate its effectiveness. This paper focuses on construction phase of project development and is intended for the use by project managers.
