최근 온톨로지 모듈을 이용하여 효과적으로 온톨로지를 구축하려는 시도들이 증가하고 있으며 이에 따라 다양한 온톨로지 모듈화 기법들이 제안되어왔다. 이들 기법들은 각각의 모듈화 목표와 기준을 바탕으로 개발되어 왔으나 모듈화 기법들을 평가할 수 있는 공통된 기준 및 평가 프레임워크가 정립되지 않아 서로 비교하기 어려운 실정이다. 또한 온톨로지와 관련된 평가에 대한 연구들이 지금까지 활발히 이루어져 왔지만 주로 온톨로지 단위의 평가가 중심이 되어왔으며 온톨로지 모듈화 기법의 평가에 대한 가시적인 연구들이 부족하다. 그러나 획일적이고 대용량인 온톨로지 사용의 문제점과 모듈화 필요성에 대한 인식과 함께 온톨로지를 모듈화하는 작업에 대한 평가 필요성이 제기되고 있다. 그러므로 본 연구에서는 온톨로지 모듈화 작업 과정과 모듈화 결과물인 모듈 그리고 모듈화 도구에 대한 총괄적인 평가를 제공하는 프레임워크를 제안한다. 또한, 본 연구에서 제시한 평가 프레임워크를 실증적 실험을 통해 SWOOP, PATO, Prompt 등 모듈화 기법에 적용하였다. 본 연구의 결과를 통하여 온톨로지 엔지니어들이 온톨로지 모듈화 작업의 품질을 개선시킬 수 있고 온톨로지 사용자들이 사용 목적에 맞는 온톨로지 모듈화 기법을 선택할 수 있도록 한다.

Purpose - To meet the needs of various customers in an uncertain market environment, many companies use product modularization strategies. Modularization of a product means that one product consists of several components and that the type of product can be changed according to the combination of components. The greatest feature of modularity is that changes in one component do not significantly affect the physical changes in the other component to which they are connected. Modularization of products is recognized as a very important strategy to reflect increasingly complicated customer requirements to products and respond to the needs of various markets. Many studies have been made in connection with the concept of mass customer satisfaction. There are many prior studies that modularization of such products positively affects the operational performance (manufacturing cost, fast delivery, etc.) and innovation of the product. However, excessive modularization has been found to have a negative effect on this performance. However, there are very few studies on the nonlinear relationship between product modularization and customer satisfaction. Supplementing these academically insufficient parts is very necessary when considering the current market environment. Research design, data, and methodology - In order to make up for the shortcomings of academic research in Korea, this study collects data through questionnaires in electronic, auto, and defense industry. This is because these industries are using modularity of products. based on lots of previous studies and information overload theory, we made two hypothesis and verify with empirical analysis. All 108 data were used. We used the R program and SPSS program for statistical verification. Results - As a result of the study, modularization of products showed positive relationship with customer satisfaction to a certain level. However, it has been found that when the modularization is over and beyond a certain level, there is a negative relationship with customer satisfaction. Conclusions - Excessive modularization of products can have a negative impact on customer satisfaction. This result can be understood as a result of human limited rationality due to information overload. Therefore, it is important for companies to apply appropriate modularity to product design.

The exchangeability of subassembly has a good relationship with the modularization of product. This relationship can be found by the analysis of the characteristics of a product. The weight for decision factors for the modularization can be determined by the exchangeability of a product or subassembly. The functions, structure, materials of subassembly are used as the decision parameters of exchangeability. Using these selected parameters, the modularization of a product, the characteristics of product structure, and the product function are analyzed. And then, the weighting factors could be calculated quantitatively using this relationship and the parameters of the exchangeability. The calculated weight can contribute to help a designer design for recycling (DFR), design for energy (DFE) and Eco-design.

The construction technology for reactor vessel internals (RVI) modularization is one of the most important factors to be considered in reducing the construction period of nuclear power plants. For RVI modularization, gaps between the reactor vessel (RV) core-stabilizing lug and the core support barrel (CSB) snubber lug must be measured using a remote method from outside the RV. In order to measure RVI gaps remotely at nuclear power plant construction sites, certain core technologies must be developed and verified. These include a remote measurement system to measure the gaps between the RV core-stabilizing lug and the CSB snubber lug, an RVI mockup to perform the gap measurement tests, and a new procedure and schedule for RVI installation. A remote measurement system was developed previously, and a gap measurement test was completed successfully using the RVI mockup. We also developed a new procedure and schedule for RVI installation. This paper presents the new and improved installation procedure and schedule for RVI modularization. These are expected to become core technologies that will allow us to shorten the construction period by a minimum of two months compared to the existing installation procedure and schedule.

A module design aims to develop product architecture that consists physically detachable units such as module. To develop the system of module design, this paper suggests the methodology of part grouping, evaluation of modularization of a product for improving modularization. To determine modules, module concept is proposed to satisfy the objectives of a modular design. Therefore, there are functional, structural, and process modularizations in a modular concept. Module grouping can be accomplished by using an optimization model that maximizes the sum of the weighting. The present study proposes the p-median model and the direct clustering technique. The optimal clustering solution can be obtained by comparing two clustering techniques. To find the best solution among part groups, evaluation of modularization is performed based on the concept of module design. For the evaluation of modularization, evaluation criteria of modularization are used in the matrix table.

승용차의 아키텍처는 어떻게 진화해왔는가? 그간 승용차 아키텍처에 대한 논의는 통합형, 모듈형, 그리고 두 유형의 공존 등이 혼재되어 왔다. 이에 따라 본 연구에서는 글로벌 무역 자료를 활용하여 제품의 중층 구조를 반영한 모듈화의 진전 측정 지수를 개발하고, 이를 아키텍처 유형 프레임워크에 적용하여 승용차 아키텍처의 모듈화 진행을 종단적으로 분석하였다. 분석결과 승용차 아키텍처는 지난 2000년 이후 모듈화가 지속적으로 진행되었음을 확인하였으며, 동시에 모듈화 진행은 구성 모듈 별로 상이한 것으로 나타났다. 모듈 중에는 프론트-엔드, 운전석 및 시트 모듈의 모듈화 진행이 뚜렷함을 확인된 반면, 차체 도어 천장 모듈은 소비자 니즈 충족을 위한 외부 디자인 차별화 및 완성차와 모듈업체 간 상호 조율강화로 인해 모듈화가 더디게 진행됨을 관찰하였다. 또한 샤시, 엔진, 그리고 트랜스미션 모듈로 구성된 플랫폼은 모델 다양화, 생산 원가 절감, 신제품 개발 기간 단축을 위한 완성차 업계의 지속적인 노력에 따라 모듈화가 지속 진전됨을 확인하였다. 플랫폼 구성 모듈 중에서는 트랜스미션의 모듈화 진전이 가장 두드러진 반면 샤시와 엔진 모듈은 완성차 업체의 자체 혁신 노력으로 인해 비교적 통합형 아키텍처 경향이 강한 것으로 나타났다. 본 연구는 제품 아키텍처의 모듈화를 계량적으로 측정, 그 진행을 종단적으로 측정할 수 있는 접근법을 제시하는데 기여하였다. 또한 모듈 별 상이한 모듈화 진전에 대한 고찰을 통해 관련 연구의 분석 수준의 세분화 필요성을 제안하였다. 아울러 본 연구는 승용차 산업 전반에서 일어나고 있는 아키텍처 모듈화 진전 현상을 규명함으로써 완성차 업체 뿐 아니라 모듈 업체의 아키텍처 선택과 그에 따른 전략 수립의 가이드라인을 제시하였다. 본 연구가 다양한 제조업과 그 제품의 모듈화 진전을 규명하는데 활용되기를 기대한다.

The purpose of this study was to suggest a silver blouse design by applying modularization. The precedent study of the researcher was used to analyze the design characteristics that were displayed in domestic and foreign silver blouses. This study was taken as the follow-up research as the module components and range of the silver blouse were set up and it was based on to suggest a silver blouse design with application of modularization. The intention was to base on the module system used in various fields to apply the modularization method on the module design research of silver blouse and as a result, it was derived into 6 types. The traditional design reflected on the characteristic of how the silver generation prioritizes practicality and in order to emphasize this, it will be more effective to apply the fastener and folding method for the development of the design. The contemporary design reflected on the characteristic of how the silver generation prioritizes aesthetics and in order to emphasize this, it will be more effective to apply the module composition method where integration can be made according to the desire of the wearer for the development of the design. The trendy design reflected on how the characteristic of the silver generation wants to look younger and the derived modularization method can be applied freely for expression. Since the range, structure, and formation where modularization can be applied are general, it is implied that there is a need to take sustainable development has to be conducted as the tool that can create different types of design.
