The systematic criteria and rational standard for site selection of marine recreational floating architecture are in urgently need in respect of structural safety, use of facilities, economics of construction and management, relationship with surrounding areas or cities and impact on marine environment. Nevertheless, at present, there is not any study nor guideline for site selection of marine recreational floating architecture which is now being planned and elected at many places of a body of water such as river or coastal area all over the country. Therefore this study is to propose a systematic process and a rational criteria and guideline for site selection of marine recreational floating architecture. Especially the results are suggested in forms of diagrams and tables in order to be utilized so easily by related local governments and individual enterprises.

As the requirement of Semantic Web and knowledge management has been rising, ontology developments have been carried out actively. Ontology is now at the point that systematic developing standardization should be made up like the developing a large scale software. Yet, It has not been made to optimize and standardize ontology development methodologies. In this study, to compare ontology development methodologies, METHONTOLOGY, CommonKADS, OTK in foreign countries and EOE in Korea are selected. The evaluating method is to introduce CMM-I version 1.1 framework. Ontology development methodologies have been evaluated in process areas that introduce for CMM-I maturity level 2 and 3. The purpose of this study is to find matured process and weak process in ontology development methodology on the view of process maturity, and suggests the areas to be Improved in it. The result of this study can be applied as basic data to establish and improve ontology development methodology.

This paper proposes to apply machine learning to the process of predicting the slab thickness based on the structural analysis results or experience and subjectivity of engineers in the design of bridge data construction to enable digital-based decision-making. This study aims to build a reliable design environment by utilizing machine learning techniques to provide guide values to engineers in addition to structural analysis for slab thickness selection. Based on girder bridges, which account for the largest proportion of bridge data, a prediction model process for predicting slab thickness among superstructures was defined. Various machine learning models (Linear Regress, Decision Tree, Random Forest, and Muliti-layer Perceptron) were competed for each process to produce the prediction value for each process, and the optimal model was derived. Through this study, the applicability of machine learning techniques was confirmed in areas where slab thickness was predicted only through existing structural analysis, and an accuracy of 95.4% was also obtained. models can be utilized in a more reliable construction environment if the accuracy of the prediction model is improved by expanding the process

In this study, we suggested the design thinking process that was possible to be introduced in science education and also examined the validity of the process in terms of group creativity. To do this, the design thinking process applicable to science education was selected from a variety of design thinking processes developed abroad, and then the process was modified and supplemented. We created the education program based on the developed design thinking process and applied it to high school students. The results revealed that we could offer the design thinking process through the five stages: 'understanding knowledge', 'empathy', 'sharing perspective', 'generating idea', and 'prototype'. With the results of the application of the program, we could confirm the relationship building and information seeking attributes in the understanding knowledge stage and the user-orientation, relationship building, and interpersonal understanding attributes in the empathy stage. We could also find the organization of the team attribute in the sharing perspective stage and the analytical strategic thinking attributes in the generating idea stage. Finally, the communication and analytical strategic thinking attributes in the prototype stage were confirmed. All of the key attributes of the group creativity found from skilled professionals were not confirmed from the students. However, we could ascertain the possibilities that the students should experience the process of group creativity and learn the relevant values through the developed design thinking process.

폐기물 가스화는 생산된 합성가스를 이용하여 발전 등 직접적인 에너지원으로 이용할 수 있으며, 고부가가치 화합물의 원료 공급원으로도 이용할 수 있다. 폐기물 가스화를 이용한 고부가가치 화합물 제조의 경우 기존 화합물 제조공정에 폐기물 가스화 공정이 연계되어, 하나의 복합시스템으로 운영이 된다. 따라서 기존 공정과 최적으로 연계될 수 있는 폐기물 가스화 시스템의 개발 또는 선정이 필요하며, 이를 위하여 폐기물 가스화 시스템에 대한 분석 평가가 적절하게 이루어져야 한다. 본 연구에서는 시스템공학 개념을 적용하여 폐기물 가스화 시스템의 체계적인 분석 평가를 위한 프레임워크를 개발하였다. 시스템공학은 요건분석, 기능분석, 합성(통합), 분석/관리 프로세스를 통하여 시스템을 성공적으로 구현하기 위한 다학제적인 접근방법이다. 이러한 시스템공학의 개념 및 기본 프로세스를 적용 조정하여 폐기물 가스화 분석 평가 프레임워크를 개발하였으며, 개발된 프레임워크는 계층구조로 표현이 된다. 계층구조는 분석관점, 분석항목, 분석지표로 구성이 되며 분석된 데이터에 대한 평가는 AHP를 통하여 계산된 가중치를 적용하여 이루어진다.

This study concerned the interoperability between the structural-analysis model and the default detail model in steel structures available for the structural-design process based on BIM. The purpose of the study was to develop an interface module that can perform data conversion between the analysis and design applications and the BIM applications, through the dotnet frame work development environment using OpenAPI provided by the BIM application vendor. The direct-link method was applied for BIM interoperability. A basic-frame model for detail design and modeling was created from the structural-analysis model to verify if the application was developed. Finally, the proposed process was compared with the existing process to verify the efficiency of the former.

6시그마 프로세스는 정의(Define), 측정(Measure), 분석(Analyze), 개선(Improve), 관리(Control) 라는 다섯 Step을 통하여 문제를 해결하고 성과를 달성한다. 이 다섯 단계 중에서 측정 단계는 6시그마로는 길에서 매우 중요한 전이 단계로서 문제점을 정교하게 다듬고 근원적 원인 규명을 시작하는 데 도움을 준다. 즉 개선 하고자 하는 영역에 대한 사실적 근거를 제공 받기 위해 프로세스를 숫자로 전환 할 때 무엇을 측정하고 어떻게 측정 할 것인가를 결정한다. 측정단계는 주로 3 Step으로 이루어진다. Step 1 은 CTQ 특성치의 선정, Step 2는 성과기준의 정의, Step 3은 측정시스템의 분석이다. F사의 6시그마 발표자료 중 측정 부분만을 집중 분석하여 문제점 및 그 개선 방향을 제시하려한다.
