  • In Korea, public infrastructure projects employ "long term continuation (LTC) contracts," which require budgets to be reevaluated and re-appropriated annually throughout the multi-year life of the project. However, such contracts also make it susceptible to frequently changing government policies, in which budgets required for existing projects are allocated to new projects and thus does not provide a consistent stream of capital to multi-year projects. Each year, the KEC needs to attain government funds for construction of its multiple highway construction sites. Because it is difficult to know the amount that may be actually appropriated to KEC in a given year, it is in turn difficult to anticipate and provide sufficient funds necessary for construction to run smoothly and continuously. The lack of a good logic for appropriation has resulted in projects having a skewed distribution of capital. To get better budget appropriations from the central government, the KEC first needs a systemized approach that rationalizes the annual construction capital optimally required for its individual sites. The goal of this research was to devise a way that allows the KEC to determine and calculate the optimal construction costs that would be required for its individual construction sites on an annual basis. Both the optimal progress rate and the essential work types were assessed through a workshop with 24 professionals (KEC employees and contractors) who had extensive experience in KEC projects and also were currently working in these projects.

  • The purpose of this study is to analyze the design characteristics of external appearances of Hundertwasser's housing projects through both literature review and field study, and to understand how Hundertwasser's architecture philosophy was embodied in the design of external appearances so such projects. The subjects of the analysis are: Hundertwasser House; In the Meadow Bad Soden; The Forest Spiral Darmstadt; and The Green Citadel Magdeburg. The conclusion of the study is as follows. The fundamental architecture philosophy of Hunderwasser is the close linkage between mankind and nature. He has proven, through his four housing projects mentioned above, that it is possible to build houses without destroying and in harmony with nature. Hundertwasser had identified vitality, irregularity and diversity as being the source of beauty of nature. Using the human creativity, he had embodied such elements into his housing projects, thus suggesting an ideal housing environment whereby humanity is respected. Hundertwasser made use of organic curved line and spiral shapes that exist in nature when designing his housing projects. His creativity was articulated through vitality, diversity, and irregularity in colour schemes and a wide range of form. Indeed, he was an architect pursuing the underlying nature of both human and nature. The current living environment in Korea can be characterized as being standardized and desolate, which is a result of housing projects being focused too much on functionalism. Through its analysis of Hundertwasser's housing projects, one of the objectives of this study is to contribute to a new design paradigm being called for today, including for housing projects to be more ecological and environmental-friendly. By motivating architects and appealing to their clients, this study hopes to motivate those involved in various housing projects to think progressively. Such an attitude change could assist in transforming and thus enhancing the overall living environment in Korea.

  • Information strategy planning (ISP) pursues alignment of business strategy and IT (Information Technology) strategy as well as derivation of feasible and valuable IT projects. However, conventional ISP methodology hardly obtains the objectives because of its intrinsic shortcomings. Diverse ways are proposed for the improvement of the conventional methodology including, for example, combination of EA (Enterprise Architecture) with ISP. Meanwhile, six-sigma methodology which is characterized by quantification, scientific and systematic approach, customer orientation, process orientation has been gaining considerable attention and extending its application scope continuously. In this paper, an innovative ISP methodology is proposed by decomposing activities, methods, and tasks from conventional ISP process and reorganizing them into DMADOV six-sigma framework. In addition, the usefulness and applicability of the newly proposed methodology are provided using an electronics company example. The methodology enhance the possibility of producing future oriented and beneficial IT projects by associating IT strategy and the projects in the form of quantified causal relationship. Besides, it can also increase the objectivity of IT vision and strategy.

  • Several algorithmic models have been proposed to estimate software cost and other management parameters. In particular, early prediction of completion time is absolutely essential for proper advance planning and a version of the possible ruin of a project. However, estimation is difficult because of its similarity to export judgment approaches and for its potential as an expert assistant in support of human judgment. Especially, the nature of the Norden/Rayleigh curve used by Putnam, renders it unreliable during the initial phases of the project, in projects involving a fast manpower buildup, as is the case with most software projects. Estimating software development effort is more complexity, because of infrastructure software related to target-machines hardware and process characteristics should be considered in software development for DCS (Distributed Control System). In this paper, we propose software development effort estimation technique using adaptive neural fuzzy inference system. The methods is applied to case-based projects and discussed.

  • Nowadays the Design-Build Delivery Method in public sector has been remarkably grown up in applying owing to its merits such as shortening construction duration. The Fast-Track is the wide-using method for accelerating schedule at Design-Build projects. But the public agency is in trouble to execute Fast-Track because of the lack of guideline for its process. As a result, in some cases applying Fast-Track methods, cost and construction duration are increased more than cases of non-Fast-Track projects. In this study, through the questionnaire surveys to professionals having actual implementation experiences as a construction manager, owner or general contractor, key success vehicles of Fast-Track are induced.

  • Today's highly competitive construction scenario forces all the major players in the field to take up multiple projects which have put an undue pressure on the resources available within the organization. Under such a situation, there are many instances where in the resource requirement exceeds its availability due to multiple activities (with same resource requirement) which are scheduled to start simultaneously and thus results in the constrained resource becoming a bottleneck of the project. As a consequence of sharing resources, this paper studies the impact on the completion date of two similar projects under two different conditions, the first one resulting in a postponed end date and the second without any postponement. The resource utilization, the possibility of substitution of a resource and its subsequent impact on the deadline of the project is analyzed under these two circumstances. The study is done on a Critical Chain Project Management (CCPM) platform instead of leaving the schedule with a traditional Critical Path Method (CPM) finish, which gives an added advantage of validating the robustness of the emerging CCPM trend in the field of resource management.

  • The aim for this study is to suggest a practical model to measure the financial values of the achievements from corporate research and development(R&D) projects. Performance indicators for R&D projects were identified from the extensive literature reviews and the evaluation methods to convert them into financial values were proposed to overcome the problems of excessive predictions and subjective expert assessments in existing methods. The proposed model was applied to R&D projects of an IT company in Korea for its validity test. The model is expected to be a turning point in economic evaluation of corporate R&D projects in general due to its practical and reasonable scheme.

  • Considering Japan's Greenhouse Gas (GHG) emissions reduction target for Fiscal Year (FY) 2030, the Joint Crediting Mechanism (JCM) was analyzed in order to estimate its significant contribution to Japan's Nationally Determined Contribution (NDC) and check its availability as a new mechanism to achieve Korea's 2030 mitigation target of 11.3% using carbon credits from international market mechanisms. The total budget for JCM Model Projects (1.2 billion JPY/yr) and JCM REDD+ Model Projects (0.8 billion JPY/yr), which are expected to deliver at least 50% of issued credits to Japan, is estimated about 21.6 billion JPY by the year 2030. This budget is about one third of the purchase of carbon credits from international carbon markets. So far, JCM credits of $378tCO_2-eq$. have been allocated to Japan, which are about 77% of the total issued credit through five-JCM Model Projects implemented from the year 2014. It is expected that Japan will obtain about $0.5MtCO_2-eq$. credits more from 100-ongoing JCM Projects, which are only 1% of Japan's NDC target through JCM credits. With regard to regular issued credits from implemented projects, expected new issued credits from pipeline projects and the less budget for JCM implementation as compared to purchasing carbon credits, JCM credits can be reached a resonable level of Japan's NDC target of $50{\times}100MtCO_2-eq$. through JCM until FY 2030.
