  • In recent years, semi-metallic Bismuth (Bi) has attracted significant attention due to very large magnetoresistance (MR) at room temperature originating from long carrier mean free path l and small effective carrier mass m*[1, 2]. In particular, the MR behavior and long carrier mean free path l in Bi thin films can be exploited for spintronic devices, e.g. magnetic field sensors and spin-valve transistors. In present work, we present the magnetotransport properties of the electroplated and sputtered Bi thin films in the temperature range 4-300 K. (omitted)

  • The eggs of most animal species are surrounded by an extracellular matrix known as chorion, egg envelope, egg coat, or zona pellucida. Development of fish embryo usually takes several days in an aquatic environment. During embryonic development, the chorion must protect embryo from physical damage and microbial infection in the exposed aquatic environment. (omitted)

  • In recent years, semiconductor spintronics has been rapidly developing due to potential device applications, in which the spin of charge carriers (electrons or holes) provides novel functionalities to carry signals and process information. Diluted magnetic semiconductors (DMSs) are well known to exhibit intriguing properties such as carrier-mediated ferromagnetism and spin-dependent transport resulting from the coupling between the charge transport states and the magnetic moments (spin) [1-3].

  • Eosinophilic inflammation is the main histological correlate of airway hyperresponsiveness and tissue injury in the pathogenesis of bronchial asthma. Interleukin (IL)-5 appears to be one of main proinflammatory mediators that induce eosinophilic inflammation. Allergic IL -5-deficient mice do not generate eosinophilia in the bone marrow, blood or lung in response to allergen provocation. (omitted)

  • This paper explores the features, patterns and strategies of innovation in knowledge intensive service (KIS) suppliers in Korea. It was found that characteristics of service innovation and manufacturing innovation tend to converge. Also, diverging elements were found particularly in organizational dimension in the innovation of the service sector. Investigation into the case of information and communication technology (ICT) services revealed that KIS suppliers are active in innovation. They obtained ideas required for their innovations from their knowledge activities inside firms and in the process of interaction with user firms. Large KIS suppliers are to a great extent interested in R&D for innovation, while small and medium suppliers are interested in developmental work. Weak knowledge flow was found between KIS suppliers and the public sector like universities and public research institutes.

  • ABSTRACT-The purpose of the present study was to evaluate the bioequivalence of two enalapril maleate tablest, $Renitec^{TM}$(MSD Korea Ltd.) and $Enalace^{TM}$(Welfide Korea Ltd.), according to the guidelines of Korea Food and Drug Administration (DFDA). Twenty-four normal male volunteers, 22.33 ${\pm}$ 2.55 year in age and 66.54 ${\pm}$ 8.30 kg in body weight, were divided into two groups and a randomized 2${\times}$2 cross-over study was employed. After two tablets containing 10 mg of enalapril maleate per tablet were orally administered, blood was taken at predetermined time intervals and concentrations of enalapril in plasma were determined using LC-MS-MS.

  • The study in river basin has been performed for the identify water quality impaired stream segments, to create a priority ranking of those segments, and to calculate the heavy metal ion distribution for each impaired segment based on chemical and physical water quality standards. Two methods for modeling the potential area-specific heavy metal distribution are pursued in this study. First, a novel approach focuses on distance. Heavy metal distribution can be associated with a particular small geographic area. Based on the derived estimates an distribution map can be generated. Second, the approach is used the near watershed by means of kriging interpolation algorithm. These approaches provide an alternative distribution mapping of the area. The exposure estimates from both of these modeling methods are then compared with other environmental monitoring data. A GIS-based model will be used to mimic the hierarchical stream structure and processes found in natural watershed. Specifically, the relationship between landscape variables and reach scale habitat conditions most influential found in the Abandoned mine will be explored.
