Research ArticleOpen accessIn the author namesA Note on the Improvement of Evaluation System in Wholesale Markets of Agricultural and Fishery ProductsYoon-Doo Kim, Seok YoonProblem statement: He transaction of public wholesale markets accounts for the highest rate in the distribution of agricultural and fishery products. Though the physical distribution system has improved through the revolution in distribution of 32 nationwide wholesale markets, the evaluation system in wholesale markets has not been established properly. With a rapid change of distribution environment surrounding wholesale markets such … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 6,888 accessesView PDFCite
Research ArticleOpen accessIn the author namesAdjustment of Peak Streamflows of a Tropical River for UrbanizationAta Amini, Thamer Mohammad Ali, Abdul Halim B Ghazali, Bujang Kim HuatPeak runoff from a catchment is influenced by many factors such as intensity and duration of rainfall, catchment topography, catchment shape, land use and other variables. For a particular catchment, landuse change and other human activities will alter the characteristic of catchment hydrograph. Problem statement: As a result of urbanization, the magnitude of floods occurring in a catchment increased. It … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,550 accessesView PDFCite
Research ArticleOpen accessIn the author namesOn the Views of Carbon Tax in KoreaHeon-Goo KimTo comply with the UNFCCC agreement, many countries are expected to make efforts to reduce the greenhouse gas emission level down to 1990 by the year of 2012. The agreement is intended to reduce the consumption of fossil fuel that causes the greenhouse effect. The global warming has been accelerated by the greenhouse effect resulted from the CO2 emission and … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the author namesTraffic Signal Using Smart Agent SystemCheonshik Kim, You-Sik HongIn this research, we propose an electro-sensitive traffic light using the smart agent algorithm to reduce traffic congestion and traffic accidents. The multi-agent system approach can provide a new and preferable solution. The proposed method adaptively controls the cycle of traffic signals even though the traffic volume varies. Consequently, we reduce the car waiting time and start-up delay time using … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,958 accessesView PDFCite

The conclusion of the study shows (1) in terms of DEA measurement in order to compare with efficiency of business performance and R … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the author namesExistence and Uniqueness Conditions for the Maximum Likelihood Solution In Regression Models For Correlated Bernoulli Random VariablesDavid Todem, KyungMann KimWe give sufficient and necessary conditions for the existence of the maximum likelihood estimate in a class of multivariate regression models for correlated Bernoulli random variables. The models use the concept of threshold crossing technique of an underlying multivariate latent variable with univariate components formulated as a linear regression model. However, in place of their Gaussian assumptions, any specified distribution … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,844 accessesView PDFCite
Research ArticleOpen accessIn the author namesQuery Pattern-based Relational Data to XML Data Translation AlgorithmJinhyung Kim, Dongwon Jeong, Doo-Kwon BaikThis paper proposes a new query pattern-based relational schema-to-XML schema translation (QP-T) algorithm to resolve implicit referential integrity issue. Various translation methods have been introduced on structural aspects and/or semantic aspects. However, most of conventional methods consider only explicit referential integrities specified by relational schema. It causes several problems such as incorrect transformation, abnormal relational model transition and so on. … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,192 accessesView PDFCite
Research ArticleOpen accessIn the author namesNew RFID System Architectures Supporting Situation Awareness under Ubiquitous EnvironmentsDongwon Jeong, Young-Gab Kim, Hoh InMany sensors providing situation data will be in everywhere under the ubiquitous environment. The current RFID system should be extended to recognize and use situation information from the sensors. This study proposes RFID system architectures that are suitable for the ubiquitous environment. This study applies the situation awareness concept to and extends the current RFID system architecture to be able … …Journal of Computer Science, Vol. 1, Issue 2 · 28 Jul 2006 · 7,047 accessesView PDFCite
