animal centrifuge device (WKU, Korea). The turn- table was rotated ata constantrate of56 rpm,and achieved a resultant linear acceleration of 2 g acting on the animal along the back-to-abdomen axis (Takeda etal,1996).Anim- als were placed in the centrifuge cage for 30 min before rotation to adapt to the cage,and rotation was performed in darkness to avoid visual stimulation.Animals were rota- ted... Altered environmental gravity, including both hypo- and hypergravity, may result in space adaptation syndrome. To explore the characteristics of this adaptive plasticity, the expression of immediate early gene c-fos mRNA in the vestibular related tissues following an exposure to hypergravity stimulus was determined in rats. The animals were subjected to a force of 2 g (twice earth's gravity) for 1, 3, or 12 h, and were examined poststimulus at 0, 2, 6, 12, and 24 h. RT-PCR (reverse transcription... -

orientation 1. Introduction Carbon fbers, recognized as advanced engineering materials, have the potential to provide solutions to a broad range of challenging problems, including world energy and environmental issues. In comparison to commercial dominantly carbon fbers derived from polyacrylonitrile, those produced from liquid crystal mesophase pitch have higher modulus, higher electrical and... Taguchi’s experimental design was employed in the melt spinning of molten mesophase pitch to produce carbon fibers. The textures of the obtained carbon fibers were radial with varied crack angles, as observed by scanning electron microscopy and polarized optical imaging. The diameter, crack angle, preferred orientation, and tensile modulus of the produced samples were examined to investigate the influence of four spinning variables. The relative importance of the variables has been emphasized... -

a wider range of problems with technology, including cultural, social, economic, political and environmental impacts. They investigate how technology has positively and negatively influenced the society and environment. In grades 9-12, high school students develop more topical knowledge and are encouraged to think more deeply about the impact of technology on society and the environment. Their... This study aims to explore the recently revised trend of technology-engineering literacy for students and children in the United States and the composition of benchmark contents by school level. The study can be used as basic data for revision of the technology education curriculum in Korea. In order to achieve the purpose of this study, literature research was mainly conducted.

environmental conditions. The formula for determining the daily infection rate can be expressed as fol- lows: R c = RcT × RcW × RcA × RcCS (1) In Eq. (1), Rc is the daily infection rate, RcT is the temper- ature effect, RcW is the leaf wetness (estimated from rela- tive humidity and precipitation) effect, RcA is the plant age effect, and RcCS is the plant cultivar susceptibility effect. The... Early warning services for crop diseases are valuable when they provide timely forecasts that farmers can utilize to inform their disease management decisions. In South Korea, collaborative disease controls that utilize unmanned aerial vehicles are commonly performed for most rice paddies. However, such controls could benefit from seasonal disease early warnings with a lead time of a few months. As a first step to establish a seasonal disease early warning service using seasonal climate... -

to estimate environmental conduciveness for bacterial inoculum build-up prior to the panicle emergence and infection during the panicle head- ing period. In this study, crop data on cultivars and heading dates of rice grown at 29 rice paddy fields in 2014 were collected from the National Crop Pest Management System (NCPMS) of the Rural Development Administration of Korea. Heading dates of 14... 29 locations representing major rice growing areas in Korea using regression analysis and two-way contingency table analysis. Temporal changes in weather conduciveness at two locations in 2014 were also analyzed with regard to daily weather conduciveness (Ci) and the 20-day and 7-day moving averages of Ci for the inoculum build-up phase (Cinc) prior to the panicle emergence of rice plants and the infection phase (Cinf) during the heading stage of rice plants, respectively. Based on Cinc and Cinf... -

9 days after inoculation. ..PAGE:7 Model of Bacterial Spot on Hot Pepper 131 Identifying necessary environmental factors for infection based on the monitored field data. By performing simple regression analysis of severity (response variables) and various meteorological data (explanatory variables), we chose several regression models with high R 2 and included temperature, precipitation, and... A population model of bacterial spot caused by Xanthomonas campestris pv. vesicatoria on hot pepper was developed to predict the primary disease infection date. The model estimated the pathogen population on the surface and within the leaf of the host based on the wetness period and temperature. For successful infection, at least 5,000 cells/ml of the bacterial population were required. Also, wind and rain were necessary according to regression analyses of the monitored data. Bacterial spot on...
