본 연구에서는 대학의 연구진들이 구성주의적 원리에 따라 설계한 교사-연구자간 협력적 연수 프로그램에 참여한 중등 과학 교사들이 구성주의적 수업을 내면화하는 과정을 탐색하였다. 연수 프로그램은 강의와 워크숍 및 소집단 활동 과정으로 구성되었다. 강의에서는 과학교육계의 동향 및 과학수업 프레임웍을 소개하고,워크숍에서 녹화된 실제 과학 수업 분석을 통하여 프레임웍에 대한 이해를 심화하였다. 소그룹 활동에서는 연구자와 참여 교사가 협력하여 프레임웍을 적용한 수업 모듈을 설계하였다. 지구과학을 전공한 4명의 중등 과학 교사가 자발적으로 워크숍에 참여하였다. 협력적 연수 프로그램은 전 과정을 녹화하였으며,반구조화된 면담을 연수 전과 후에 실시하였다. 녹음 및 녹화된 자료는 모두 전사하여 분석하였다. 참여 교사들은 프레임웍을 내면화하는 과정에서 주목하는 대상이 서로 달랐으며,다양하고 구별되는 교사의 경험과 교육 신념,교육 현실인식 등과 같은 다양한 요소들이 내면화 과정에서 갈등을 일으키거나 또는 그 과정을 촉진하였다. 수업 설계시 고려 요소를 결정하는 데에는 교사의 수업 경험과 학습자에 대한 인식이 중요한 영향을 미쳤다. 한편 참여 교사들은 주로 논의되었던 '탐구','적용', '모델' 등의 개념에 대해서 일상적인 의미로 받아들이거나,자신이 기존에 가지고 있던 개념으로 해석하는 경향을 보였다. 참여 교사들은 수업 시간에 비해서 기르칠 내용이 과다하다고 인식하고 있어서 수업 모듈을 설계하는 과정에서 내용은 강의식으로 전달하고,실험은 구성주의적 방식으로 설계하는 등 수업 구조를 이분화하려는 경향을 보였다. 본 연구 결과는 구성주의적 교사 연수와 교사 전문성 발달 과정에 의미있는 시사점을 제공할 것이다.

Despite the importance of knowledge complementarities (KC) to firm performance, very little is known about exactly what constitutes KC and how synergistic knowledge is created in KC. This research looks into the dimensionality of KC and how synergistic knowledge as an essential component of KC is generated in a process innovation (PI) project. We propose that KC consists of potential complementary knowledge, collaborative elaboration (CE) process, and synergistic knowledge. The model is investigated quantitatively, using a sample of 26 matched-pairs of client and consultant who participated in a PI project, and then qualitatively using interviews of a sub-sample of 7 matched-pairs of client and consultant. Data were collected in a longitudinal way at four different points during the four month project period. Results show that consultant's learning about the client's business occurs first and then client learning about IT capabilities follows through CE. With this enhanced clients' knowledge about IT capabilities, clients play an initiative role in designing the To-Be business processes, while consultants play a supporting role by introducing best practices or making suggestions based on their experiences. Future research implications as well as practical implications are also discussed.

Collaborative Robot (Cobot) that can collaborate with humans by fusion with many advanced technologies among industrial robots in the industrial field are attracting attention. In this study, the engineers of Small and Medium Enterprises can directly participate in the cobot design, and ultimately, the possibility of deriving the shape design of the differentiated cobot was studied. The method applied to derive the shape design of differentiated cobot is 'Morphological Analysis'. First, the design elements of the form of cobots were derived as 'Link' and 'Joint'. In addition, by analyzing the image form of the Link and Joint of the existing cobot, a new form element of the Link and Joint was proposed. In order to quantitatively identify the most discriminating cobot shape design, FGI (Focus Group Interview) was conducted to derive image types of 4 Link and 3 Joint. Then, the most important 'Shape Combination' was carried out in morphological analysis, and 12 new cobot shape designs were drawn. Through this, the applicability of the morphological analysis method in the derivation of differentiated cobot shape design was examined.

The purpose of this research is to develop a collaborative architectural design system. Design collaboration requires an extensive use of communication methods as well as the participation of various experts from different domains. Such facts address several issues when the Internet and digital media are able to create a completely new work environment. The building design process was studied, and possible modes of design collaboration were defined. A prototype system is being developed in accordance with the defined collaboration model. The system integrates a set of communication tools and web-based design media. Such media include a synchronous multi-user web CAD tool, a schematic 3D design tool, and a electronic whiteboard. A project database was designed in order to coordinate the project-wide communication which elaborates technologies such as web-based data access. In order to find out the effectiveness of the system, a usability test was performed both in quantitative and qualitative manner. The research will contribute to the development of world-wide design and construction collaboration through the Internet, which is becoming a mainstream building process model.

It is becoming more and more difficult to cope with new knowledge and technology required by society by the efforts of one person or organization according to the development of science and technology. As a method to overcome this, collaborative research is becoming important. This tendency is increasing in the government R&D projects as well, and the 'A' test research institute, which is the subject of this paper, is also increasing a collaborative research. The purpose of this study is to analyze the network characteristics among the participating researchers in the government R&D project conducted by the institution A, and to ascertain how the network characters of the researchers actually affect the financial performance of the team. The results of the analysis show that 'closeness centrality' and 'degree of centrality' contribute positively to the financial performance of the team. On the other hand, 'betweenness centrality' and 'eigenvector centrality' have a negative effect on the financial performance of the team because they are not directly related to financial performance.

Security issue in mobile ad hoc network (MANET) is a promising research. In 2011, we had accomplished a survey of black hole attacks in MANETs. However network technology is changing with each passing day, a vast number of novel schemes and papers have been proposed and published in recent years. In this paper, we survey the literature on malicious attacks in MANETs published during past 5 years, especially the black hole attack. Black hole attacks are classified into non-cooperative and collaborative black hole attacks. Except black hole attacks, other attacks in MANET are also studied, e.g., wormhole and flooding attacks. In addition, we conceive the open issues and future trends of black hole detection and prevention in MANETs based on the survey results of this paper. We summarize these detection schemes with three systematic comparison tables of non-cooperative black hole, collaborative black hole and other attacks, respectively, for a comprehensive survey of attacks in MANETs.

When turning to determining a subject position for the digital age, one may look beyond the invention of its technologies and instead begin with the development of its aesthetic of networked communities, nodal expression, and collaborative identity. Virginia Woolf's The Waves demonstrates this aesthetic in both form and content. In this paper, I will examine the role of collaboration in the form of interdisciplinary composition, arguing that Woolf's use of musical form and dramatic monologue and dialogue structurally secure an investment in collaborative models of expression. Digital texts taut their inherent multimodality, but such compositions are also evident in pre-digital texts. In addition, I will decipher the subject position Woolf puts forward in The Waves by looking closely at how the characters determine their own identity and existence when they are alone, when they interact with one individual, and when they congregate as a group. These are exemplified more specifically in the representations of Rhoda and Bernard as equally refusing to collaborate between a self-defined identity and a group defined identity; Bernard's channeling of Lord Byron while writing a love letter; and Woolf's use of the red carnation as a repeated image of the intertwined nature of the characters' collaborative identity and mutual dependence on one another.

With the rapid development of the Chinese water project, the safety monitoring of dams is urgently needed. Many drawbacks exist in dams, such as high monitoring costs, a limited equipment service life, long-term monitoring difficulties. MEMS sensors have the advantages of low cost, high precision, easy installation, and simplicity, so they have broad application prospects in engineering measurements. This paper designs intelligent monitoring based on the collaborative measurement of dual MEMS sensors. The system first determines the endpoint coordinates of the sensor array by the coordinate transformation relationship in the monitoring system and then obtains the dam settlement according to the endpoint coordinates. Next, this paper proposes a dual-MEMS sensor collaborative measurement algorithm that builds a mathematical model of the dual-sensor measurement. The monitoring system realizes mutual compensation between sensor measurement data by calculating the motion constraint matrix between the two sensors. Compared with the single-sensor measurement, the dual-sensor measurement algorithm is more accurate and can improve the reliability of long-term monitoring data. Finally, the experimental results show that the dam subsidence monitoring system proposed in this paper fully meets the engineering monitoring accuracy needs, and the dual-sensor collaborative measurement system is more stable than the single-sensor monitoring system.
