Objectives: This study compares cases of Dalgubeol Health Care Project, 301 Network Project, and 3 for 1 Project based on program logic models to derive measures for promoting integrated healthcare and welfare services centered around medical institutions. Methods: From January to December 2021, information on the implementation systems and performance of each institution was collected. Data sources included prior academic research, project reports, operational guidelines, official press releases, media articles, and written surveys from project managers. A program logic model analysis framework was applied, structuring the information based on four elements: situation, input, activity, and output. Results: All three projects aimed to address the fragmentation of health and welfare services and medical blind spots. Despite similar multidisciplinary team compositions, differences existed in specific fields, recruitment scale, and employment types. Variations in funding sources led to differences in community collaboration, support methods, and future directions. There were discrepancies in the number of beneficiaries and medical treatments, with different results observed when comparing the actual number of people to input manpower and project cost per beneficiary. Conclusions: To design an integrated health and welfare service provision system centered on medical institutions, securing a stable funding mechanism and establishing an appropriate target population and service delivery system are crucial. Additionally, installing a dedicated department within the medical institution to link activities across various sectors, rather than outsourcing, is necessary. Ensuring appropriate recruitment and stable employment systems is needed. A comprehensive provision system offering services from mild to severe cases through public-private cooperation is suggested.

The concept of construction information systems (IS) is very comprehensive and subjective. Acronyms in relation to the construction IS may include BIM, CIC, IT, nD-CAD, ERP, CALS, KM and so on. These terminologies are used in a somewhat mixed way causing possible misunderstandings in research and practice of construction information systems. Moreover, ever-changing construction business environment has widely affected the roles and methods of utilizing construction IS. Examples of these changes are dissemination of alternative project delivery systems, global standardization under highly competitive overseas market, and advancement of information and communication technologies. In this context, the purpose of this paper is to propose a high-level framework for information systems in the construction industry. Several different concepts in the area of construction IS were investigated first in order to identify the major variables of the framework. Trends of research and real-world implementations were then analyzed to support the rationale of the variables. Finally, a framework was proposed by re-arranging the relevant issues. Findings of this paper indicate that different acronyms commonly share many similar concepts in their definitions, however, in each acronym, the motivations and approaches to implementing construction IS are very different. Different approach can provide maximum effectiveness, while overlaps may happen causing practical inefficiency.

Understanding the current status of a construction project is necessary to achieve successful on-site management. Real-time information delivery is a major concern for construction industry practitioners in order to expedite decisions and discussions. We propose the use of a first personal view (FPV) system of a quadcopter drone as a tool for monitoring on-site status and communicating between construction participants. The most important function of the drone FPV system is its ability to visually monitor construction site situations in real time. An on-site management system process is developed, verified, and applied to several construction work tasks after determining factors that affect efficient construction management. The proposed system is expected to assist the construction manager in achieving high efficiency.

In the situation where there should be a gap between the design environments of 2D drawing and 3D BIM modeling, it is unavoidable aspect to face confusion caused by parallel usage of both technologies unless the project delivery systems are entirely upgraded to 3D. Therefore, it is critical to make efforts to minimize this confusion. Meanwhile, detailed drawings have very important roles in the construction process because they do not only concretely express construction methods for a given design plan but also provide basis for quantity takeoff and construction cost estimation etc. This paper suggests a plan to standardize detailed information based on BIM standard framework in order to make BIM realize the information. In the short term, this plan provides improved environment where both BIM and CAD technologies can be applied and, in the long term, it provides bases for BIM to replace CAD technology.

Construction firms have long sought success in the global construction market through diversifying revenue sources and project portfolios. The volume of international contracts has contributed to firms' sustained growth by mitigating the impact of the domestic market's cyclical nature. In spite of the importance of international construction, the uncertainty and dynamic changes surrounding global construction pose serious threats to global contactors. Over the last decade, the international construction industry has changed drastically in many ways, particularly including financial resource diversity, competition rules for the selection of contractors, and the terms of delivery systems requiring more competent total service providers. This paper investigates the important changes for global contractors through various documentation analysis as well as in-depth interviews with industry experts. This paper then analyzes the common strategies and lessons obtained from the cases of leading global contractors that have sustained their growth in the competitive global construction during the last decade. In addition, the authors further analyzed the comparisons between those firms and Korean contractors to discern any difference in sustaining their growth in the competitive market. It was found that those leading firms were quite proactive and responsive to changing markets by diversifying their market revenues to stabilize their revenue structure and enhancing their competency through a wide range of 'business convergence'. In addition, they significantly increased their upstream/downstream functional capabilities; hence becoming more competent service providers, able to grow in these rapidly changing market conditions. Finally, this paper benchmarks the critical strategies that support growth, which in turn can provide a strategic guideline for expansion into the global construction market.

Urban regeneration is a large-scale program that must address challenges such as a significant number of involved projects, diverse participants and their conflicting objectives, and a long life span. In an effort to address these issues, the Interactive Electronic Technical Manual (IETM) is applied to urban regeneration in order to provide a guideline to enhance urban regeneration program management. Through a survey, three major functionalities required in the IETM are identified: process map provision, customized information delivery, and communication ability with other information systems. To achieve these functionalities, the development framework of the IETM and the associated technologies are examined.Its characteristics can be sum up ontology-driven metadata, user-oriented process map composition system and so on. Finally, the usage scenarios of the IETM are discussed.

Global Electronic Trading means that trading partners trade each other via Global Electronic Trading Network, that is, global business to business electronic commerce. Electronic payment systems are how to make payment electronically in manner that is efficient, reliable, and secure. I suggest the Electronic payment systems such as TradeCard and SWIFT enable seller and buyer to conduct and settle international B2B electronic commerce in case of solving the above problems. And, where the cargo arrives ahead of the B/L, the importer cannot take delivery of the cargo without the B/L. This situation is referred to as the B/L dilemma. But the BOLERO system will resolve this B/L dilemma. Bolero Project is developing a cross industry utility platform for the secure, electronic transfer of commercial trade information world wide.

Mobility is an essential human need. Human survival and societal interaction depend on the ability to move people and goods. Efficient mobility systems are essential facilitators of economic development. Cities could not exist and global trade could not occur without systems to transport people and goods cheaply and efficiently. Rail has been considered as one of the important components of the transportation infrastructure required to service and improve the performance and productivity of an economy. In Nigeria, the rail infrastructure built by the colonial master several decades ago has been left in a state of total deterioration. This long neglect was occasioned by the failure of the government to pay adequate attention to infrastructure development. There is a vital and urgent need for rail infrastructure development in Nigeria. This study presents a systematic review of the evolution of rail, the current nature of railway infrastructure delivery in Nigeria, and offers possible suggestions on how to achieve an effective and sustainable rail infrastructure delivery in Nigeria. A thorough literature search of academic databases was conducted on current research trends on the subject of railway infrastructure by systematically reviewing selected published articles from reputable research domains. The analysis of the selected articles revealed the following among others (1) the existing railway infrastructure is in a state of mess and not sustainable, and (2), Government's investment/commitment in rail infrastructure seems inadequate compared to what is obtainable in other developed countries. Rail infrastructure development cannot be left to the Federal government of Nigeria to solve on its own; collaboration and participation are required. Government as a matter of priority should devote considerable attention to the development of rail infrastructure to harness the economic potential and transformation that sustainable rail infrastructural projects will provide.

During a construction project, construction managers must be provided with material information to help them to make decisions more efficiently without delaying the delivery of material. Construction work can be smoothly performed with the proper material supply. Construction duration depends on several material-related decisions, including the order, delivery, and allocation of material to the correct work location. Hence, it is worthwhile to introduce data warehouse techniques that generate subject-oriented and integrated data to construction material management. The data warehouse for construction material management can perform multidimensional analysis and then define KPIs (Key Performance Index) in order to provide construction managers with construction material information such as lead time, material delivery rate, material installation rate and so on. This research proposes a method of effectively facilitating large amounts of data in the operating systems during the construction management process. In other words, the proposed method can supply structured and multi-perspective material-related information using data warehouse techniques.
