본 논문에서는 modularity를 기반으로 한 향상된 커뮤니티 추출 알고리즘을 제안한다. 기존의 알고리즘은 modularity 값을 증가시키는 커뮤니티를 구축할 때 노드가 갖고 있는 정보를 고려하지 않음으로써, 계산을 비효율적으로 반복하여 수행한다. 제안하는 알고리즘은 노드의 degree(weight)를 계산하고 그것을 내림차순으로 정렬하고, 정렬된 순서대로 modularity 값의 증가여부를 확인함으로써, 반복되는 계산과정을 줄여 기존의 알고리즘보다 빠르게 최종 결과를 도출해낸다. 실험계산을 통해 제안하는 알고리즘이 더 짧은 시간 내에, 기존알고리즘이 구한 modularity 값보다 같거나, 향상된 값을 찾는다는 것을 보인다.

Clothing design is one of design products for human, the end user and corresponds to artifacts. Sometimes artifacts with one mono module exist, and so does artifacts assembled and combined with multi modules of same shape and size or various shapes and sizes and thus all design products can be understood by modularity concept. The purpose of this study was to make a new suggestion for the clothing design and production of high uniqueness and creativity by reviewing and synthesizing the foundation of clothing modularity concept as the original clothing design figures from the history have shown various modularity concept evolution from mono module to multi module stages. The methods of this study were to identify clothing modularity and analyze the type, evolving direction, and category of clothing modularity, and the value of clothing modularization design through comprehensive literature reviews on topic-related books and theses. The original clothing figures with Significance from the clothing history were analyzed in evolution sequence for application direction and value of clothing modularity in flat pattern. Clothing modularity in ancient clothing figures was classified as three types of the fixed, drapery, and straight lined in evolving direction from clothing of mono module to flat patterned clothing. The direction of clothing modularity was identified as mono- dual-triple-multi into another level of multi modularity after intentional devolution. The categorization of clothing modularity was identified in terms of clothing flat construction, clothing design construction, and clothing form modeling. The value of clothing modularization design using clothing modularity was identified as economical efficiency, convenience, promptitude, adaptability, functionality, and creativity.

We review the current understanding of modularity in biological motor control and its forms, and then relate this modularity to proposed modular control structures for biomimetic robots. We note the features that are different between the robotic and the biological 'designs' with features which have evolved by natural selection, and note those aspects of biology which may be counter-intuitive or unique to the biological controls as we currently understand them. Biological modularity can be divided into kinematic modularity comprised of strokes and cycles: primitives approximating a range of optimization criteria, and execution modularity comprised of kinetic motor primitives: muscle synergies recruited by premotor drives which are most often pulsatile, and which have the biomechanical effect of instantiating a visco-elastic force-field in the limb. The relations of these identified biological elements to kinematic and force-level motor primitives employed in robot control formulations are discussed.

고객의 요구나 선호도가 다양해짐에 따라 제품의 다양화가 필요하지만, 이는 오퍼레이션스의 비효율성이 야기될 수 있어 기업의 중요 관심사가 되고 있다. 따라서 원활한 오퍼레이션스 기능 수행을 위해 기업들은 제품의 모듈화 구조를 도입해 왔다. 하지만 신제품 개발 과정에서 모듈화의 효과를 계량적으로 분석한 연구는 미흡하다. 이에 본 연구는 기존 제품에 신기술이 포함된 부품이 도입되는 제품개발의 상황에서 모듈화가 기업의 수익에 미치는 영향에 관한 계량모델을 개발하고 이를 분석하여 몇 가지 중요한 명제를 도출함으로써 신제품 개발 시 고려해야 할 신기술 도입 및 모듈화의 의사결정에 필요한 가이드라인을 제시하였다. 연구 결과, i) 제품의 업그레이드가 용이하거나, ii) 외부요인으로 인해 제품의 가격이 높게 책정되어야 할 경우, iii) 신기술 투자비용의 효과가 불확실할 경우, 모듈화 수준을 높이는 노력이 필요하고, 모듈화에 대한 수요탄력성이 낮은 제품의 신제품 개발 시에는 신기술 도입의 투자비용을 늘리는 것이 바람직하다.

In today's turbulent business landscape, a firm's ability to explore new IT capabilities and exploit current ones is essential for enabling organizational agility and achieving high organizational performance. We propose IT exploration and exploitation as two critical organizational learning processes that are essential for gaining and sustaining competitive advantages. However, it remains unclear how the emerging cloud-based IT architecture affects an organization's ability to explore and exploit its IT capabilities. We conceptualize modularity and virtuality as two critical dimensions of emerging cloud-based IT architecture and investigate how they affect IT exploration and exploitation. We test our hypotheses using data obtained from our field survey of IT managers. We find that modularity is positively associated with both exploration and exploitation whereas virtuality is positively associated with exploration, but not with exploitation. We also find that the effect of modularity on exploitation is stronger than its effect on exploration.

본 연구는 소셜 네트워크 그래프에서 커뮤니티로 탐색된 2개의 커뮤니티를 하나의 커뮤니티로 통합하는 방법을 연구한다. 모듈래러티는 커뮤니티의 품질을 보여주는 측정치이다. 통합하여야 할 커뮤니티에 에지를 추가함에 따라, 커뮤니티의 품질은 증가하게 된다. 커뮤니티를 통합하기 위해서, 각 커뮤니티의 모듈래러티 값을 이용하여, 추가하여야 할 에지 수를 결정하는 방법들을 제안한다. 단순 그래프를 이용한 실험계산을 통해 통합된 커뮤니티의 모듈래러티 값이 통합하기 전의 각각의 커뮤니티의 모듈래러티 값보다 크게 만드는 방법이 유효한 커뮤니티 통합 방법임을 보이고. 그 방법이 적용될 수 있는 그래프의 조건을 확인한다. 이 결과를 이용하여 실제 소셜 네트워크 예에 대한 실험계산을 통해 본 방법의 유효성을 확인한다.

In this paper, we propose a block-based modularity architecture design method for distributed machine learning. The proposed architecture is a block-type module structure with various machine learning algorithms. It allows free expansion between block-type modules and allows multiple machine learning algorithms to be organically interlocked according to the situation. The architecture enables open data communication using the metadata query protocol. Also, the architecture makes it easy to implement an application service combining various edge computing devices by designing a communication method suitable for surrounding applications. To confirm the interlocking between the proposed block-type modules, we implemented a hardware-based modularity application system.

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.

It is difficult to design system software to meet a better separation of concerns, which can provide a number of benefits such as adaptability, extensibility, and modularity in the design and implementation. During design, some aspectual properties, such as synchronization, scheduling, performance and fault tolerance, crosscut the basic functionalities of the system software. By separating functional components from the different aspectual components of the system software in the design, we can provide a better generic design model of system software. Aspect-Oriented Programming is a methodology that aims at separating components and aspects from the early stages of the software life cycle, and using techniques to combining them together at the implementation phase. In this paper we discuss an aspect-oriented framework that can simplify system software design and implementation by expressing it at a higher level of abstraction. Our work concentrates on how to achieve a higher separation of aspectual components, functional components, and layers from each other. Our goal is to achieve a better design model for implementing system software in terms of modularity, reusability and adaptability.
