  • Recently, BIM has been widely applying in civil engineering projects centering on the private construction industry in order to establish self guidelines for spreading in practice. However, most BIM technologies and software are based on the architectural projects. In these environments, it is not easy to apply the BIM to a infrastructure field. Even BIM standards with IFC (Industry Foundation Classes) are also focusing on architectural projects. Especially, both private and public sectors do not know about how BIM delivery system should be performed, and how such deliverable should be submitted to the government yet. Thus, we need to analyze an application level of BIM S/W (Software) in real projects and verify their interoperability. Besides, since there are not any common standards that can exchange IFC models for civil engineering projects, we have many issues in converting as-built infrastructure models into IFC and delivering their design documents to the government. Accordingly, this study aims to perform a BIM process with commercial software for real road project after a detailed design process is finished and verify interoperability between diverse BIM software for securing BIM data reliability.

  • Wikipedia is composed of millions of articles, each of which explains a particular entity with various languages in the real world. Since the articles are contributed and edited by a large population of diverse experts with no specific authority, Wikipedia can be seen as a naturally occurring body of human knowledge. In this paper, we propose a method to automatically identify key entities and relations in Wikipedia articles, which can be used for automatic ontology construction. Compared to previous approaches to entity and relation extraction and/or identification from text, our goal is to capture naturally occurring entities and relations from Wikipedia while minimizing artificiality often introduced at the stages of constructing training and testing data. The titles of the articles and anchored phrases in their text are regarded as entities, and their types are automatically classified with minimal training. We attempt to automatically detect and identify possible relations among the entities based on clustering without training data, as opposed to the relation extraction approach that focuses on improvement of accuracy in selecting one of the several target relations for a given pair of entities. While the relation extraction approach with supervised learning requires a significant amount of annotation efforts for a predefined set of relations, our approach attempts to discover relations as they occur naturally. Unlike other unsupervised relation identification work where evaluation of automatically identified relations is done with the correct relations determined a priori by human judges, we attempted to evaluate appropriateness of the naturally occurring clusters of relations involving person-artifact and person-organization entities and their relation names.

  • Research collaboration is an important strategy to improve research output, and virtual academic communities (VACs) have become an important platform to collaborate on. This paper reveals the influencing factors of researchers' collaboration intention in VACs from two attributes: individual, and inter-members. On the basis of the Social Cognitive Theory, Social Exchange Theory, social network theory, and Five-Factor Model, this paper constructed a model demonstrating the influencing factors of VACs researchers' collaboration intention. A self-administered questionnaire was employed on members of four VACs in China to collect data; subsequently, 558 usable responses were analyzed using structural equation modeling. The result showed that openness, conscientiousness, reciprocity, trust, and the social network characteristic had a significant influence on the collaboration intention of researchers in VACs, while self-efficacy, agreeableness, extroversion, neuroticism, and experience had no significant effects on the collaboration intention of researchers in VACs. This model plays a positive role in promoting the research collaboration intention of Chinese VACs researchers and in guiding the construction of VAC platforms.

  • The purpose of this paper is to examine the Banks's Examination of Documents in the L/C Transactions. Most of all, this article deals with one of most important aspects of the law on documentary credits, namely, the compliance of documents presented with the terms and conditions of a letter of credit. In addition, the general principles of strict compliance will be considered and in the next, the requirements of specific documents such as invoices, transport documents and insurance policies. This area of letter of credit law is shaped not only by judge-made decisions but also the articles of Uniform Customs and Practice for Documentary Credits, the International Standard Banking Practice(ISBP Publication No.745) prepared by the Banking Committee of the International Chamber of Commerce as well as the position papers and opinions of the latter. Whether a document complies with the terms of a letter of credit is essentially a matter of examination and construction of the document in question against the terms of the letter of credit under which it is presented, articles of the UCP, ISBP as well as the opinions and statements of the Banking Committee. Most of all this article was focused on provisions of UCP600. Comparison with provisions of UCP500 have been drawn where appropriate.

  • FEED (Front End Engineering and Design) is the key area that determines the competitiveness of procurement and construction in the EPC contracts especially in terms of the added value. Nevertheless, previous researches in FEED have been limited to the process and deliverable of design work or the particular management business function (e.g. System Engineering, collaboration, information etc.). In this context, the purpose of this study is to propose a comprehensive FEED structure and its functions from the project management perspective throughout the whole project life-cycle for thermal power plants. Proposed FEED business procedures are classified into three levels; First level is the classification of FEED business phases, the second level defines major FEED management functions, and the third level is detailed FEED functions. A survey using proposed FEED functions and assessment variable was conducted in order to analyze the current status and the areas for future improvement. It is expected that the proposed structure, functions, and evaluation methodology for FEED management will contribute to effective practice of FEED as well as to improvement of competitive capability for engineering, procurement, and construction (EPC) companies.

  • Construction value engineering(VE) is often performed in the form of a short term review of designs, rather than during a regular workshop with a standardized work plan, and its application method is limited. Thus, tasks are performed by applying the method in reverse depending on the VE results, and function analysis, a key VE method, is omitted or only applied for the sake of formality. In addition, it is hard to expect great results from VE because of insufficient time and budget allowed to perform VE and a lack of understanding of VE procedures and methods. In particular, the methods used to store and reuse the tremendous amount of ideas and information created during the process of VE implementation is not systematic. Even the Korea Expressway Corporation, which has produced relatively systematic VE performance compared to other institutions, has had the above-mentioned problems. Therefore, this study aims to improve existing VE processes and suggest a method to efficiently store and retrieve VE information by analyzing the limitations of construction VE practice and the characteristics of VE for highway facilities as part of improving design VE performance.

  • Recently, with the development of data processing technology and the increase of computational power, methods to solving social problems using Artificial Intelligence (AI) are in the spotlight, and AI technologies are replacing and supplementing existing traditional methods in various fields. Meanwhile in Korea, heavy rain is one of the representative factors of natural disasters that cause enormous economic damage and casualties every year. Accurate prediction of heavy rainfall over the Korean peninsula is very difficult due to its geographical features, located between the Eurasian continent and the Pacific Ocean at mid-latitude, and the influence of the summer monsoon. In order to deal with such problems, the Korea Meteorological Administration operates various state-of-the-art observation equipment and a newly developed global atmospheric model system. Nevertheless, for precipitation nowcasting, the use of a separate system based on the extrapolation method is required due to the intrinsic characteristics associated with the operation of numerical weather prediction models. The predictability of existing precipitation nowcasting is reliable in the early stage of forecasting but decreases sharply as forecast lead time increases. At this point, AI technologies to deal with spatio-temporal features of data are expected to greatly contribute to overcoming the limitations of existing precipitation nowcasting systems. Thus, in this project the dataset required to develop, train, and verify deep learning-based precipitation nowcasting models has been constructed in a regularized form. The dataset not only provides various variables obtained from multiple sources, but also coincides with each other in spatio-temporal specifications.

  • SISP(strategic information system planning) is an important part of IS management. Through it, organizations establish effective long-term use of IS and ensure their support of organizational objectives. This entails establishing priorities for implementation of new applications, developing policies and procedures for managing the IS function and IS services, and construction of information architecture. Many studies have tried to improve SISP practice by discussing planning problems, identifying factors critical to the success of planning efforts, and providing methodologies for carrying out the process. Others tested the appropriateness of formal SISP under varying contextual circumstances and examined a number of contextual variables for their effects on SISP practice and its effectiveness. In this paper, the two criteria(the improvement of planning capabilities and the fulfillment of planning objectives) of successful SISP will be given and the relationship between organizational variable(IS-present role, IS-future role, formalization, time horizon) and improvement of planning capabilities will be analyzed. And then the relationship between improvement of planning capabilities and fulfillment of planning objectives will be examined. Specific description about the purpose of this study is as follow: (1) What are the determinants of successful SISP? (2) Which contextual factors are important and how strong are their influences to the improvement of planning capabilities? (3) How important is the improvement of planning capabilities to the fulfillment of planning objectives?

  • Environmental conservation plan, notwithstanding their feasibility and potential utility in construction of environment-friendly spaces, has long been perceived in practice as "declarative" and a "formality." Such perceptions are largely the result of the failure to provide spatial planning that is directly relevant to development of the space in question, and to sufficiently interconnect with urban development plan. This demonstrates the need for ways to link disparate plans, i.e. to enact "spatial environment plan." In response to these issues, this study proposes the systematization of spatial environment data as a necessary prerequisite to the establishment of spatial environment plan, which would provide both linkages with other plans, and ensure the applicability of environmental conservation plan. To this end, this study analyzed existing environmental data, and then proposed systems for links with spatial environment plan. In respect of this, the study examined spatial data systems, and then classified applicable spatial according to each environmental medium. The study also produced spatial information and planning items that can be included in spatial environment plans for each of the nine environmental media, and then constructed a system that could link the existing spatial information system, current spatial environment data, and spatial environment management plan. Furthermore, the study proposed matters for improvement in the construction of spatial environmental data to ensure the activation of spatial environment plan. The construction of a systematic spatial database, by facilitating the smooth establishment of spatial environment plan, can enhance and upgrade environmental conservation plan, while contributing to enhanced linkages with related spatial plans.
