Purpose - This study primarily aims to represent the current trend of research on CPFR as a promising supply chain collaboration program and proposes a new framework for analyzing any collaboration programs in terms of three key collaborative features. Research design, data, and methodology - This study employs a literature review of selected studies that conduct research on CPFR. CPFR is analyzed based on the proposed framework that characterizes collaboration programs in terms of three key collaborative features. Results - The analysis based on the proposed framework reveals that the current form of CPFR continues to have some collaborative features that are not fully utilized to create an advanced collaboration program. The literature review indicates that most past studies ignore critical issues including the dynamic nature of the multiple-stage supply chain system and negotiation process for collaborative agreement in CPFR implementation. Conclusions - Results indicate that CPFR can become a better supply chain collaboration program by incorporating coordinative cost payment and joint decision making processes. Based on observations on the existing literature of CPFR, this study indicates several important issues to be addressed by future studies.

In the future, a machine will be more improved in the form of advanced concept with collaborative ability in M2M(Machine to Machine, Mobile to Machine) environment for u-Manufacturing system. This paper tried to standardize M2M and design advanced concept machine. The M2M is front-end system for implementing autonomous ubiquitous environment. The advanced machine in M2M will be a collaborative machine with knowledge-evolutionary ability such as u-Machine(Ubiquitous machine), Vortal(Vertical Portal) machine and P2P(Peer to Peer) machine. Such advanced concept machines will be the key subject for M2M cooperation.

Recommender systems help consumers to find the useful products from the overloaded information. Researchers have developed content-based recommenders, collaborative recommenders, and a few hybrid systems. In this research, we extend the classic collaborative recommenders by clustering method to form a hybrid recommender system. Using the clustering method, we can recommend the products based on not only the user ratings but also other useful information from user profiles or attributes of items. Through our experiments on well-known MovieLens data set, we found that the information provided by the attributes of item on the item-based collaborative filter shows advantage over the information provided by user profiles on the user-based collaborative filter.

협동학습이 효과적으로 이루어지기 위해 가장 중요한 요소는 학습자의 여러 특성을 고려한 모둠 구성에 있다. 모둠 구성이란 원활하게 협동학습을 진행하기 위해 학습자들을 다양한 특성에 근거하여 모둠을 구성하는 것이다. 잘못된 도구의 선정으로 인해 모둠의 구성이 제대로 이루어지지 않을 경우 학생들의 불만이 수업으로 이어져 학습의 효과로까지 나타나는 문제가 발생할 수 있다. 본 논문에서는 학습효과 향상 및 불링 경향성 진단을 함께 고려한 모둠 구성 도구를 구현하였다. 소시오메트리 설문을 통한 학생들 간의 학급선호도와 학생의 성적을 입력받아 교사의 주관에 맞게 모둠을 구성함으로써 학습 효과도 고려할 수 있고 더불어 불링 경향성도 진단할 수 있는 모둠 구성 도구를 제안하고자 한다. 이를 통해 교사는 학습 효과를 증진 시킬 수 있는 수업 진행이 가능한 협동학습뿐만 아니라 학생들의 교우관계를 미리 파악해 학급 내에서 일어날 수 있는 불링에 미리 대처할 수 있을 것으로 기대한다.

In searching for potent cancer chemopreventive agents from synthetic or natural products, 28 randomly selected flavonoids were screened for inhibitory effects against partially purified aromatase prepared form human placenta. Over 50% of the flavonoids significantly inhibited aromatase activity, with greatest activity being demonstrated with apigenin $(IC_{50}: 0.9{\mu}/mL)$, chrysin $(IC_{50}: 1.1{\mu}/mL)$ , and hesperetin $(IC_{50}:1.0{\mu}/mL)$.

In this paper, the numerical inverse kinematics analysis is presented for a collaborative robot with an offset wrist. Robot manipulators with offset wrist are widely used in industrial applications, due to many advantages over those with wrist center and those with three parallel axes such as simple mechanical design, light weight, and so on. There may not exist a closed-form solution for a robot manipulator with offset wrist. A simple numerical method is applied to solve the inverse kinematics with offset wrist. Singularity is analyzed using Jacobian matrix and the numerical inverse kinematics algorithm is implemented on the real-time controller.

Tele-Gesture is a tangible user interface(TUI) device that allows a user to physically point to a 3D object in real life and have their gestures play back by a robotic finger that can point to the same object, either at the same time, or at another point in time. To understand the extent of the gestures as new way of digital collaborative communication, collaboration situation and types were experimented as TUI implementations. The design prototype reveals that there is a rich non-verbal component of communication in the form of gesture-clusters and body movements that happen in an digital communication. This result of analysis can contribute to compile relevant contributions to the fields of communication, human behavior, and interaction with high technology through an interpretive social experience.

태깅은 사용자들이 공유된 콘텐츠에 키워드의 형태로 메타 데이터를 추가하는 과정이다. 최근 이러한 태깅은 웹 상 에서 더 많은 사용자들에게 사용되어지고 있는 추세인데, 이런 태깅 사이트는 사용자가 북마크, 사진, 비디오 등의 콘텐츠에 태그를 추가할 수 있도록 한다. 본 논문에서는 사용자의 참여를 바탕으로 하는 태깅 시스템의 구조와 배경 지식 또 이런 시스템이 가지는 다양한 의미와 한계들을 분석한다. 또한 WordNet 데이터베이스의 동의어 집합을 태그의 검색에 적용한 TagPlus 시스템을 제안하고 Flickr 이미지 공유 시스템으로부터 동의어 태그 검색을 가능하도록 구현하였다.

The purpose of this study is to analyze the effects of Critical Thinking Strategy supporting argumentation activities between learners. The research question is whether the form of Critical Thinking Strategy offered to support meaningful interaction of collaborative argumentation between learners influences the knowledge acquisition, learning outcome, and student satisfaction. For this, the collaboration outcome of the group, the level of individual knowledge acquisition, the level of students satisfaction were measured as outcome of argumentation activity and their differences analyzed. This study concludes the following: A comparison of the group that was provided with Critical Thinking Strategy (test group) and the group provided with general argumentation scaffolds (compared group) showed there wasn't statistically significant differences in the quality of the learning outcome of collaboration between the groups and in students satisfaction. But there was significant difference in the degree of individual acquisition depending on the offering of scaffolding for Critical Thinking. Therefore, as premised in this study, supporting meaningful mutual interaction between learners during collaborative argumentation using Critical Thinking Strategy has a positive influence on the individual acquisition of domain knowledge. The group provided with scaffolding for Critical Thinking gained higher effect in the degree of knowledge sharing and individual acquisition of domain knowledge compared to the group provided with general argumentation scaffolding.
