  • This paper presents a memory efficient tree based anti-collision protocol to identify memoryless RFID (Radio Frequency Identification) tags that may be attached to products. The proposed deterministic scheme utilizes two bit arrays instead of stack or queue and requires only ${\Theta}(n)$ space, which is better than the earlier schemes that use at least $O(n^2)$ space, where n is the length of a tag ID in a bit. Also, the size n of each bit array is independent of the number of tags to identify. Our simulation results show that our bit array scheme consumes much less memory space than the earlier schemes utilizing queue or stack.

  • Comparative molecular analysis has been frequently adopted for the authentication of herbal medicines as well as the identification of botanical origins. Roots and rhizomes of the family Umbelliferae have been used as traditional herbal medicines to relieve various symptoms such as inflammation, neuralgia and paralysis in countries of East Asia. Since most herbal medicines of the Umbelliferae roots or rhizomes are generally supplied in the form of dried slices, morphological examination does not often provide sufficient evidence to identify the botanical origin. Using species-specific probes developed by the comparative analysis of nrDNA ITS sequences, a DNA chip was developed to identify herbal medicines for 13 species in the Umbelliferae. The developed DNA Chip proves its potential as a rapid, sensitive and effective tool for authenticating herbal medicines in future.

  • Most of the study on system identification has been carried out using input/output relation in physical domain. However identification concept of stochastic system has not been reported up to now. Interest is focused to identify an unknown dynamic system under random external disturbances which is not possible to measure. A concept to identify the system parameters in stochastic domain is proposed and implemented in terms of simulation. Attempt has been made to identify the system parameters in inverse manner in stochastic domain based on system output only. Simulation is conducted to reveal quite noticeable performance of the proposed concept.

  • The recent information society is affected by new technologies including EC(Electronic Commerce), CALS(Commerce At Light Speed), EDI(Electronic Data Interchange), telecommuting and teleconferencing. The research goal of this paper is to identify major failure factors to reduce the dysfunction of EC and to suggest possible strategies that overcome those obstacles. The research methodologies of major failure factors are very similar to those of critical success factors which were widely used in MIS research areas. Ideally EC provides the possibility of a win/win situation for vendors and consumers. A survey study was performed using questionnaires. The factor analysis was performed to identify failure factors. Several hypotheses were set up to identify the major failure factors to reduce the dysfunction of EC. The regession analysis was performed to test those hypotheses and to understand the relationships between the major failure factors identified and the performance variables such as satisfaction, usage, and usefulness. Finally, the paper suggests alternatives to activate EC in terms of regulations, social rules, a technological model, etc.

  • Hermetic rotary compressor is one of the most Important components for air conditioning system since it has a great effect on both the performance and the noise and vibration of He system. Noise and vibration of rotary compressor is occurred due to gas pulsation during compression process and unbalanced dynamic force. In order to reduce noise and vibration. it is necessary to identify sources of noise and vibration and effectively control then. Many approaches have been tried to identify noise sources of compressor. However, compressor noise source identification has proven to be difficult since the characteristics of compressor noise are complicated due to the interaction of the compressor parts and gas pulsation. In this work, Statistical Energy Analysis has been used to trace the energy flow in the compressor and identify transmission paths from the noise source to the sound field.

  • Neuropeptide Y (NPY), a 36-amino acid polypeptide, is a member of the pancreatic polypeptide family, which consists of NPY, peptide YY (PYY) and pancreatic polypeptide (PP). The neuropeptide Y (NPY) receptors called Y receptors belongs to G-protein coupled that are involved in a variety of physiological functions such as appetite regulation, circadian rhythm and anxiety. Five receptor subtypes have been cloned in mammals (Y1, Y2, Y4, Y5, and Y6) of which four are functional. In this short review, information about the functional NYP receptors was analyzed. Sequence analyses were done between these receptors to identify the relationships between them. Phylogram was generated between these receptors to identify the close homologue between these receptors. Our sequence analyses found that Y1 and Y4 receptors are close than the other receptors. Further structure based analysis could be useful to identify subtype selective antagonists and dual antagonists targeting Y1 and Y4 receptors.

  • The main purpose of this study is to suggest the new strategic management model for the future successful company. The new model consists of the following structure. First, to identify the object dimension. The upper object is to satisfy the customers needs. And the lower object is to satisfy the workers needs. Second, to identify the external enviromental problems dimensions. There are five dimensions. They are ethical responsinilities, government-business alliances, collaboration amongst competitors, innovative invester-company relations, and globalization of enterprise. Third, to identify the internal enviromental problems dimensions. There are two dimensions. They are new organizational forms and integrated subcultures. Fourth, to find the solution for the above dimensions. The solution is as follow. All the managers and workers must have business reengineering minds and apply the complexity management. And the company should construct the strategic information systems.

  • It is important to identify the exact target optical cable that a worker look for when he executes a cable construction work. Until now, An Optical cable identification work has been done by a manual pulling of an optical cable or by the method of using RF signals. But these methods not only consume much time and labor costs but also have a distance limit of the optical cable to identify. In this paper, we propose a method that uses the phase change signal of the optical interferometer to identify an optical cable. With the proposed method the field worker can have an efficient tool to prevent miscutting the optical cable and can also save operating costs.

  • This study is to suggest design types and to identify design characteristics of traditional style public buildings. Since the types of such buildings became very diverse recently, proper classification criteria is essential for future design and evaluation. The demand for such buildings is continuously increasing, but the types of design is very varied; thus it seems important to identify the present design conditions, and to be able to suggest desirable directions for better designs. The research analyzes 31 examples of public buildings in Gwangju Metropolitan City and South Jeolla Province, where there are large number of traditional style public buildings than anywhere else in Korea, and tried to analyzed site plan, elevation, space, details and organizes Design types. This study can help to roughly identify the problems of existing design as well as to suggest improvements in the future design.

  • Targeting of complex system such as human cells rather than biochemically pure molecules will be a useful approach to massively identify ligands specific for the markers associated with human disease such as cancer and simultaneously discover the specific molecular markers. In this study, we developed in vitro selection method to identify nuclease-resistant nucleic acid ligands called RNA aptamers that are specific for human cancer cells. This method is based on the combination of the cell-based selection and subtractive systematic evolution of ligands by exponential enrichment (SELEX) method. These aptamers will be useful for cancer-specific ligands for proteomic research to identify cancer-specific molecular markers as well as tumor diagnosis and therapy.
