Steel production requires high-quality surfaces with minimal defects. Therefore, the detection algorithms for the surface defects of steel strip should have good generalization performance. To meet the growing demand for high-quality products, the use of intelligent visual inspection systems is becoming essential in production lines. In this paper, we proposed a ShuffleDefectNet defect detection system based on deep learning. The proposed defect detection system exceeds state-of-the-art performance for defect detection on the Northeastern University (NEU) dataset obtaining a mean average accuracy of 99.75%. We train the best performing detection with different amounts of training data and observe the performance of detection. We notice that accuracy and speed improve significantly when use the overall architecture of ShuffleDefectNet.

The purpose of this paper is to analyze the organizational design and management of product development in creating new product architecture by an established firm. For the purpose, the paper put up the organizational design in the process of PDA(Personal Digital Assistant) development of Sharp and Casio which were Japanese major PDA firms in 1990s. PDA is the product born through architectural change from Electronic Organizer. Prior research on the product architecture change and organizational adaptation emphasized that an established firm is difficult to adapt to new product architecture due to the restriction of prior technology or organizational inertia. For overcoming these problems and successful development of new product architecture, organizational design and management in the process of product development becomes essential. In case of Sharp, corporate development project team had been used to overcome the restrictions from architectural knowledge accumulated through previous product. After launching first new PDA by corporate development project team, Sharp created a new division and pushed an evolution of PDA, when new PDA market start to grow up rapidly toward a major market segmentation. As a result, Sharp was able to build up stable PDA project trajectory. However, Casio was late for three years in launching of new PDA architecture because previous division charging of Electronic Organizer tried to develop first new PDA. Casio's PDA development was prohibited by engineers of previous division because new PDA architecture was inferior on user interface and display definition. That is, Casio's first PDA development was restricted by architectural knowledge of previous product.

In order to increase extendibility and reusability of components during component design, the variability discovered in a business application development needs to be defined to separate rules. That is because component adaptation techniques through redefinition of implementation classes and interface wrapping have limits to support the component reusability. Therefore, It's essential to design the component which takes into account the future reusability in the component development. In this paper, we extended the existing component architecture to incorporate rule components by separating variable properties from the components and defined the necessary syntax for the rule definition. In the case study, we built the business components for an insurance sales application and verified the component reusability through the rule redefining.

Information and communication technologies (ICT) have been combined with products from other industries to provide new functionality, as recently shown in the cases of Internet of Things (IoT). Modularity assumes a crucial role in such technological convergence, and has impacts on the relationship between organizations as well as competition within an industry. Interface standards, which ensure the connectivity between modules, serve as a critical factor in the process by which modularity affects organization systems and industry structure. To understand the aforementioned phenomenon, we studied modularity and interface standards with a focus on the interaction between technology and organization systems and subsequent changes in industrial dynamics. This paper examines previous literature on modularity and interface standards in the aspects of product architecture, organization systems, and institutional factors. With this analytical framework, we conducted a comparative analysis of electronic and automotive industries to derive implications for standardization policy. This research has shown the significance of external open interface standards in shaping an industrial landscape where a variety of module producers horizontally compete. It also advises that policymakers take into account product characteristics, engagement of leading firms in an industry, and institutional factors such as WTO law in the design of standardization policy.

Multi-Channel Switch ICs for IoT have integrated several solid state structure low ON-resistance bi-directional relay MOS switches with level shifter to drive high voltage and they should be independently controlled by external serialized logic control. These devices are designed for using in applications requiring high-voltage switching control by low-voltage control signals, such as medical ultra-sound imaging, ink-jet printer control, bare board open/short and leakage test system using Kelvin 4-terminal measurement method. This paper describes implementation of analog switch control block and its verification using Field programmable Gate Array (FPGA) test pattern generation. Each block has been implemented using Verilog hardware description language then simulated by Modelsim and prototyped in a FPGA board. Compare to conventional IC, The proposed architecture can be applied to fields where multiple entities need to be controlled simultaneously in the IoT environment and the proposed pattern generation method can be applied to test similar types of ICs.

RUP(Rational Unified Process) is a development process which is based on object-oriented, use case centric, architecture centric, and iterative approach. Public projects performed previously adopt waterfall lifecycle model for development of large scale software. However, recently various projects adopt an iterative approach to minimize risks of a project and to enhance quality of software. But few research result on practices of RUP as the subprocess of system development process is available. This paper presents a system development process which uses RUP as the subprocess for a subset of the system. Thus we introduce a tailored RUP for K-CIS(Korean Core Instrumentation System). Moreover, we assess the application result of K-CIS with typical waterfall lifecycle model and RUP. We believe that the results of our work are useful for tailoring a system development process with RUP, reducing risks of development, and enhancing the quality of a final product.

그간 다양한 제조업에서 발생한 후발국가의 '추격'에 대한 연구가 다수 이루어졌다. 특히 최근에는 추격을 위한 기회의 창 관점에서 새로운 후발국가에 의한 추격의 반복과 그에 따른 산업 시장 주도권의 이전을 논의하기 위한 '추격 사이클' 이론이 제시되어 몇몇 산업과 시장에서 발생한 주도권 이전에 관한 실증 연구가 등장하기 시작하였다. 그러나 산업 시장 주도권 이전 현상은 이미 광범위하게 일어나고 있으며, 이에 대한 논의의 심화와 이론의 발전을 위해서는 심층적인 실증 연구가 지속적으로 등장할 필요가 있다. 이에 따라 본 연구에서는 중국 굴삭기 시장에서 발생한 우리나라에서 중국으로의 주도권 이전의 원인과 그 과정을 추격 사이클 이론에서 제시한 세 가지 기회의 창, 즉 기술적 기회의 창, 수요적 기회의 창, 그리고 정책 제도적 기회의 창과 이에 대한 우리나라와 중국 굴삭기 산업의 전략적 대응 간 결합을 통해 고찰하였다. 먼저 기술적 기회의 창 관점에서는 굴삭기 아키텍처의 모듈화가 완제품 생산에 필요한 기술적 지식의 장벽을 낮추고 기술 학습 속도를 높임으로써 중국 굴삭기 산업의 추격과 시장 주도권 확보에 긍정적인 영향을 미친 것으로 나타났다. 한편 중국 정부의 수요산업(건설업) 육성 정책과 핵심 부품의 수입 관세 철폐, 공용 부품 표준화 정책과 같은 정책 제도적 기회의 창과 이에 대한 중국의 적극적 대응 또한 시장 주도권 이전에 긍정적인 영향을 미침을 확인하였다. 마지막으로 수요적 기회의 창의 관점에서는 2010년 이후 미니 소형 세분시장의 급속한 확대에 대한 중국의 전략적 대응이 산업 주도권 이전에 큰 영향을 미침을 발견하였다. 본 연구는 추격 사이클 이론에 대한 새로운 실증을 제시함으로써 향후 본 이론의 발전에 기여할 것으로 기대된다. 또한 본 연구 결과는 중국의 추격에 직면하였거나 이미 주도권을 넘겨준 우리나라의 제조업의 위기 극복 및 지속가능한 성장을 위한 전략과 정책 수립의 중요한 지침으로 널리 활용될 것으로 기대된다.

Product Line Engineering(PLE) is a software reuse paradigm that core assets are defined using common features in a domain and are instantiated in various applications. To apply the core asset effectively, variants which satisfy application requirements are extracted and the core asset should be also instantiated based on the variants. For the work, variability on architecture and components should be extracted exactly and an instantiation process and guidelines should be defined based on this variability In this paper, we define variability types depending on core assets elements and describe artifact templates related to tile variability. We also propose a systematic process which uses defined core assets including variability and verify practicability of the proposed process and variability expression through doing ease study. If utilizing with the proposed process in PLE, it can be feasible to model concrete core asset and variability and to utilize practical application engineering.
