Applying Particle Swarm Optimization for Enhanced Clustering of DNA Chip Data
Lee, Min-Soo ;
The KIPS Transactions:PartD, volume 17D, issue 3, 2010, Pages 175~184
DOI : 10.3745/KIPSTD.2010.17D.3.175
Experiments and research on genes have become very convenient by using DNA chips, which provide large amounts of data from various experiments. The data provided by the DNA chips could be represented as a two dimensional matrix, in which one axis represents genes and the other represents samples. By performing an efficient and good quality clustering on such data, the classification work which follows could be more efficient and accurate. In this paper, we use a bio-inspired algorithm called the Particle Swarm Optimization algorithm to propose an efficient clustering mechanism for large amounts of DNA chip data, and show through experimental results that the clustering technique using the PSO algorithm provides a faster yet good quality result compared with other existing clustering solutions.
An Efficient Adaptive Sampling Technique based on the Kalman Filter for Sensor Monitoring

The KIPS Transactions:PartD, volume 17D, issue 3, 2010, Pages 185~192
DOI : 10.3745/KIPSTD.2010.17D.3.185
In sensor network environments, each sensor measures the physical environments according to the sampling period, and transmits a sensor reading to the base station. Thus, the sample period influences against importance resources such as a network bandwidth, and a battery power. In this paper, we propose new adaptive sampling technique that adjusts the sampling period of a sensor with respect to the features of sensor readings. The proposed technique predicts a future readings based on KF (Kalman Filter). By using the differences of actual readings and estimated reading, we identify the importance of sensor readings, and then, we adjust the sampling period according to the importance. In our experiments, we demonstrate the effectiveness of our technique.
Framework for Supporting Business Services based on the EPC Network
Nam, Tae-Woo ; Yeom, Keun-Hyuk ;

Recently, there have been several researches on automatic object identification and distributed computing technology to realize a ubiquitous computing environment. Radio Frequency IDentification (RFID) technology has been applied to many business areas to simplify complex processes and gain important benefits. To derive real benefits from RFID, the system must rapidly implement functions to process a large quantity of event data generated by the RFID operations and should be configured dynamically for changing businesses. Consequently, developers are forced to implement systems to derive meaningful high-level events from simple RFID events and bind them to various business processes. Although applications could directly consume and act on RFID events, extracting the business rules from the business logic leads to better decoupling of the system, which consequentially increases maintainability. In this paper, we describe an RFID business aware framework for business processes in the Electronic Product Code (EPC) Network. This framework is proposed for developing business applications using business services. The term "business services" refers to generated events that can be used in business applications without additional data collection and processing. The framework provides business rules related to data collection, processing, and management, and supports the rapid development and easy maintenance of business applications based on business services.
Development Process Improvement of Open-market System by using Agile Methodology
Lee, Yong-Hee ; Lee, Gun-Ho ;
The KIPS Transactions:PartD, volume 17D, issue 3, 2010, Pages 203~208
DOI : 10.3745/KIPSTD.2010.17D.3.203
This study improves the productivity of software development of open-market systems using agile methodology. The current processes of an open-market system are analyzed and inefficient processes are identified which are changed by applying the agile practice principles in Lean software. This study analyzes the process lead times and defects after the processes are changed to see the improvement effect.
The Effect of Motivation-Reward Fit on Commitment and Knowledge Sharing Activities in Communities of Practice
Kim, In-Hak ; Lee, Ji-Hyeon ; Koh, Joon ; Kim, Hee-Woong ;
The KIPS Transactions:PartD, volume 17D, issue 3, 2010, Pages 209~222

As the business competition between firms is getting intense, one of the sources of competitive advantage is effectively and efficiently to create, share, and apply information/knowledge among employees. Most of the firms which conduct knowledge management are operating a Community of Practice(CoP) in order to create, share and utilize this kind of information/knowledge resource. Recently, the CoP is getting out of its informal and spontaneous manner and is beginning to be led by the top management, receiving official support, in order to achieve the organization`s strategic goals. However, the corporation`s strategic operation of the CoP is not only against its original characteristics but also hampers the spontaneity of its participants. Every participant has different motivation to participate and different preference for reward type. This study, with the survey of 114 respondents, found that intrinsic motivation as well as extrinsic motivation significantly affect the motivation-reward fitness. Also, the motivation-reward fit was found to influence CoP commitment which ultimately leads to knowledge sharing activity in the CoP context. This research will help knowledge management companies to figure out how the two things of participants` motivation and their reward types can fit together, and how such fitness ultimately affects the participants` commitment and their knowledge sharing activities.
The Effect of Composition and Security Activities for Information Security Architecture on Information Asset Protection and Organizational Performance
Jeong, Gu-Heon ; Yi, Dong-Wook ; Jeong, Seung-Ryul ;
The KIPS Transactions:PartD, volume 17D, issue 3, 2010, Pages 223~232
DOI : 10.3745/KIPSTD.2010.17D.3.223
This study was carried out for the purpose of inquiring into the effect of composition and security activities for information security architecture on information asset protection and organizational performance in terms of general information security. This study made a survey on 300 workers in the government, public institutions and private companies, which it showed that management factors of risk identification and risk analysis, in general, have an usefulness to composition and security activities for information security architecture to prevent inside information leakage. And the understanding and training factors of IT architecture and its component were rejected, requiring the limited composition and security activities for information security architecture. In other words, from the reality, which most institutions and organizations are introducing and operating the information security architecture, and restrictively carrying out the training in this, the training for a new understanding of architecture and its component as an independent variable made so much importance, or it did not greatly contribute to the control or management activities for information security as the generalized process, but strict security activities through the generalization of risk identification and risk analysis management had a so much big effect on the significant organizational performance.
Analyzing Effects of Government Promoting Policies for IPTV Adoption
Lee, Bong-Gyou ; Seo, Hyun-Sik ; Lee, Sung-Joon ; Kim, Jun-Ho ;
The KIPS Transactions:PartD, volume 17D, issue 3, 2010, Pages 233~244
DOI : 10.3745/KIPSTD.2010.17D.3.233
This research aims to examine the efficiency and effectiveness of the governmental policies promoting IPTV by verifying their influences on the adoption empirically. The government unveiled several policies including creating demands in public sectors, developing diverse public contents, subsidizing the production of converged contents, easing the regulations to promote IPTV industry. While a lot of previous literature has already proved that a system quality, a content quality, and a perceived price have influences on the adoption of IPTV, the effects of governmental policies are not well understood despite of their contributions to the adoption. Rather, most of existing research on governmental policies in the context of technology adoption have focused on regulatory frameworks. The results of the study show that governmental policies have influences on consumers` perceived system quality and content quality. It is also found that perceived system quality, content quality and perceived price have influences on adoption intention. This study can contribute to the field in a way that it proves the important roles of governmental policies in the diffusion of new technologies including IPTV.
