The objective of this paper is to estimate the concentration distribution in flow field inside the pipeline based on electrical impedance tomography. Special emphasis is given to the development of dynamic imaging technique for two-phase field undergoing a rapid transient change. Nonlinearity-compensation extended Kalman filter is employed to cope with unexpected measurement uncertainty. The nonlinearity-compensation extended Kalman filter compensates for the influence of measurement uncertainty and solves the instability of extended Kalman filter. Extensive computer simulations are carried out to show that nonlinearity-compensation extended Kalman filter has enhanced estimation performance especially in the unexpected measurement environment.

In EIT, an array of disjoint electrodes is attached on the boundary of the object and a set of small alternating electrical currents is injected into the object through these electrodes, and then the corresponding set of voltages is measured on the same array of the electrodes. The objective in EIT is to estimate the resistivity distribution inside the object based on the set of measured voltages and injected currents. In this paper, we proposed a new dynamic EIT reconstruction scheme based on the interacting multiple model (IMM) algorithm. The main contribution of the proposed scheme is that multiple models are employed for the state evolution to get around the modeling uncertainty. Extensi...

Gross lesions of multifocal interstitial nephritis, often called 'white spotted kidney', can be caused by various bacterial or viral hematogenous infections [1, 2]. The purpose of this study was to determine whether there is an association between these lesions in slaughter pigs and the causative agents in Jeju. (omitted)

Many people living in Asia countries, particularly Korea, Japan and China, have consumed very widely fresh seafood products, such as shrimps, oysters, mussels and other marine invertebrates and fishes, without any heating or cooking. A variety of Vibrio spp., including V. parahaemolyticus, V. cholera. V. vulnificus, and V. fluvialis, lives in these seafoods and cause great problems associated with human disease. A strong antimicrobial agent to effectively inhibit the growth of these pathogenic bacteria in in vivo or in vitro is urgently need for preventing fish and human diseases. (omitted)

Cacti of the genus Opuntia, which are widely distributed throughout Latin America, South Africa, the Mediterranean, and Korea, have been used not only as ornamental plants but also for their medicinal value. For example, Opuntia spp. have traditionally been used as hypoglycemic plants for treating diabetes mellitus. In this article, we review published papers dealing with the biological and medicinal properties of Opuntia spp.

Ecklonia cava is a brown alga(Laminariaceae) that is abundant in the subtidal regions of Jeju island in Korea. Phlorotannins were identified to be responsible for the biological activities in Ecklonia species. In the present study, triphlorethol-A, a phlorotannin, was isolated from Ecklonia cava and its anticancer properties were investigated. Triphlorethol-A was investigated whether it may show cytotoxicity effects against U937, HeLa, NCI-H460 and MCF-7 cancer cells by MTT test. As a result, triphlorethol-A did not show cytotoxic effects against tested four cell lines.

As the electrical power industry is restructured, the electrical power exchange is extended. One of the key information used to determine how much power can be transferred through the network is known as available transfer capability (ATC). To calculate ATC, traditional deterministic approach is based on the severest case, but the approach has the complexity of procedure. Therefore, novel approach for ATC calculation is proposed using cost optimization in this paper Cheju Island interconnected HVDC system with mainland in KEPCO (Korean Electric Power Corporation) systems, and the demand of Cheju Island increases about 10 ($\%$) every year. To supply for increasing demand, the supply of HVDC system must be increased. This paper proposed the optimal transfer capability of HVDC system between Haenam in mainland and Cheju in Chju Island through cost optimization. The cost optimization is considered production cost in Cheju Island, wheeling charge through Haenam-Cheju HVDC system and outage cost with one depth (N-1 contingency)

The animal bone-remains excavated with earthwares at Cheju Kimnyungri cave site were investigated morphologically and osteometrically. The number of bone remains were 1706 pieces by morphological criteria. Based on the classification of bony pieces excavated in the cave site, the important animal species in Cheju island during the early Tamra period (presumably between A.D.0 - A.D. 500) was as follows; wild boar(75%), deer(17%), cattle(6%), and horse in small percentage. The excavated bone remains imply that the major fauna of animal species are composed of three species, including Sus scrofa, Cervus nippon and Bos taurus. These data suggests that the archaeological remains such as bone pieces are good indicators of the fauna animals, and of zoological entity in the island.
