PLM(Product Lifecycle Management) is one of innovative manufacturing paradigms which leverages e-business technologies to allow a company's product content to be developed and integrated with all company business process through the extended enterprise. In these days, most construction companies also make an effort to enhance their systems for creating, sharing and managing information to improve business efficiency through entire lifecycle of project execution. Because of different needs, business process and diverse engineering activities such as design, structural analysis, installing simulation, documents and data managements, a new paradigm for construction companies is needed to manage and share the entire workflow, and information in total project lifecycle. In this paper, we conducted user requirement and business process analysis of the construction to design architecture of C-PLM(Construction Project Lifecycle management) and implement a prototype of C-PLM systems based on commercial PDM system.

How do we create a next generation Records Management System? Under a rapidly changing system development environment, the records management system of public institutions has remained stable for the past 10 years. For this reason, it seems to be the key cause of the structural problem of the Records Management System, which makes it difficult to accommodate user requirements and apply a new recording technology. The purpose of this study is to present a redesigned model for a next-generation records management system by analyzing the status of the electronic records management. This study analyzed "A Study on the Redesign of the Next-Generation Electronic Records Management Process," records management technology of advanced records management system, and a case of an overseas system. Based on the analysis results, the improvement direction of the records management system was analyzed from several aspects: functional, software design, and software distribution. This study thus suggests that the creation of a microservice architecture-based (MSA) and an open source software-oriented (OSS) records management system should be the focus of next-generation record management.

In an era of very rapid technological change, standardization organizations have been confronted with the problem that they should develop more new and more complex standards as strategic tools for enforcement of competitive power in shorter time according to the reduction of Life Cycle of products and the increase in the number of standards and their complexity. To cope with this challenge, worldwide Standardization Bodies now implement and operate their own EDH (Electronic Document Handling) system which is electronic means applied to development and delivery of standards based on their standardization workflow. In this paper, we analyze the EDH guidelines and methods of major Standardization Bodies, International bodies such as ITU-T, ISO/IEC JTC1, Regional bodies such as ETSI, Committee T1 of USA and TTA (Telecommunications Technology Association) of Korea. Finally, we discuss future EDH policy and suggest architecture of Advanced Standards Information System.

The main idea of this study is to propose a BIM-based automation system drawing up a report of energy conservation plan in the architecture division. In order to obtain a building permit, an energy conservation plan must be prepared for buildings with a total floor area of 500m² or more under the current law. Currently, it is adopted as a general method to complete a report by obtaining data and drawings necessary for an energy conservation plan through manual work and input them directly into the verification system. This method takes a lot of effort and time in the design phase which ultimately increases the initial cost of the business, including the services of companies specialized in the environmental field. However, in preparation for mandatory BIM work process in the future, it is necessary to introduce BIM-based automatic creation system that has an advantage for shortening the whole process to enable rapid permission of energy-saving designs for buildings. There may be many methods of automation, but this study introduces how to build an application using Dynamo of Revit, in terms of utilizing BIM, and write an energy conservation plan by automatic completion of report through Dynamo and Excel's VBA algorithm, which can save time and cost in preparing the report of energy conservation plan compared with the manual process. Also we have insisted that the digital transformation of architectural process is a necessary for an efficient use of our automation system in the current energy conservation plan workflow.

As the technical aspect of the web system development is, unlike the existing main frame or client/server environment, greatly influenced by the dynamic and variable factors and carried out in a comparatively short period, practical and efficient process to which the developer may adapt with ease is very much required for the web system development. However, while the technological substitute, language and architecture composition have been much discussed, in connection with web system development growing rapidly, standardized development process and its deliverables have been rarely discussed. This thesis analyzes problems of the existing web system development processes and as the substitutes for them, proposes web system development process based on the domain features derived from the concepts of iteration and increment. For the classification of domains, five domains in total are set by interlocking web system factors and web site types and the workflows for two domains applied to projects are incorporated focused on work content and deliverables. The proposed process applies to the development of intranet system and is compared with the existing web development processes by the measure classified into components and elements.

In this paper, we implement an automated composition system of web services using hybrid techniques that merge the benefit of BPEL techniques, with the advantage of OWL-S, BPEL techniques have practical capabilities that fulfil the needs of the business environment such as fault handling and transaction management. However, the main shortcoming of these techniques is the static composition approach, where the service selection and flow management are done a priori and manually. In contrast, OWL-S techniques use ontologies to provide a mechanism to describe the web services functionality in machine-understandable form, making it possible to discover, and integrate web services automatically. This allows for the dynamic integration of compatible web services, possibly discovered at run time, into the composition schema. However, the development of these approaches is still in its infancy and has been largely detached from the BPEL composition effort. In this work, we describe the design of the SemanticBPEL architecture that is a hybrid system of BPEL4WS and OWL-S, and propose algorithms for web service search and integration. In particular, the SemanticBPEL has been implemented based on the open source tools. The proposed system is compared with existing BPEL systems by functional analysis. These comparisions show that our system outperforms existing systems.

This research paper explores the application of FinBERT, a variational BERT-based model pre-trained on financial domain, for sentiment analysis in the financial domain while focusing on the process of identifying suitable training data and hyperparameters. Our goal is to offer a comprehensive guide on effectively utilizing the FinBERT model for accurate sentiment analysis by employing various datasets and fine-tuning hyperparameters. We outline the architecture and workflow of the proposed approach for fine-tuning the FinBERT model in this study, emphasizing the performance of various datasets and hyperparameters for sentiment analysis tasks. Additionally, we verify the reliability of GPT-3 as a suitable annotator by using it for sentiment labeling tasks. Our results show that the fine-tuned FinBERT model excels across a range of datasets and that the optimal combination is a learning rate of 5e-5 and a batch size of 64, which perform consistently well across all datasets. Furthermore, based on the significant performance improvement of the FinBERT model with our Twitter data in general domain compared to our news data in general domain, we also express uncertainty about the model being further pre-trained only on financial news data. We simplify the complex process of determining the optimal approach to the FinBERT model and provide guidelines for selecting additional training datasets and hyperparameters within the fine-tuning process of financial sentiment analysis models.
