In this study we briefly introduce the electronic float system based on the GPS and RF communication technology and present some field application results. The system is capable of operating 15 floats simultaneously for making discharge measurement. Since the electronic floats (EFs) acquire flow paths, they can improve velocity measurement accuracy up to 10%. Additionally, measured velocities by the EFs show good agreement with those by an ADCP. Relative difference in sub-section area calculated by the electronic and conventional float methods is -79~71% and, due to convergent tendency of floats flowing along near banks, it increases much larger. It is possible to improve accuracy up to 5~6% in making discharge measurement by the electronic floats at site with irregular flow paths and section arrangement. The electronic float system is capable of calculating more accurate velocity and section area using position information based on GPS. By real-time measurement of velocity, cross-section area and discharge, the electronic float system is expected to reduce manpower and improve accuracy, rapidity and efficiency of flood discharge measurements.

In this study, the sustainability of Abies nephrolepis in the presence of Tripterygium regelii was analyzed. To accomplish this, a field survey of140 stands was conducted. Based on the presence or absence of T. regelii, as well as the layer in which it was present (where appropriate), the type of T. regelii presence wasclassified as follows: TP type, indicating the presence of T. regelii in the tree and sub-tree layers; SP type, indicating its presence in the shrub layer; and A type, indicatingits absence from all layers. The indicator species analysis revealed T. regelii to be an indicator species of the TP type and SP type. The MRPP test was used to examine the differences among the types. Moreover, the seedling and DBH class analysis indicated there to be a difficulty in terms of the status competition, as the number of young trees generated by A. nephrolepis was the lowest in the TP type. The findings of this study enhanced our understanding of the vegetation structure of A. nephrolepis, thereby contributing to efforts concerningits conservation and management.

Recently, as the awareness of the necessity of entrepreneurship education has spread in secondary education, the competency of educators in the field of education has become more important. This study tried to derive the priority of education needs by exploring the competency of educators to practice entrepreneurship education and the result from analysis of the difference in importance and performance. For conducting the analysis, this study conceptualized entrepreneurship education competency based on the TPACK (Technological Pedagogical Content Knowledge) model and developed a questionnaires to measure those competencies. Using TPACK and developed questionnaires, a survey was conducted on 217 secondary school teachers who were interested in entrepreneurship education, and derived the difference between importance-level and current-level was analyzed with a t-test. As a result of the study, for all sub-factors of TPACK, the mean of importance-level was higher than the mean of current-level, indicating that educational prescription was required. Also, as a result of analysis of Borich's requirements and The Locus for Focus Model, it was found that the factor with the highest priority in education was CK(Content Knowledge). Based on the results of study, implications for strengthening competencies for entrepreneurship educators were derived.

Objectives : The sigma-1 receptor is implicated in stress, depression, psychostimulant sensitization, and addiction vulnerability. Prior studies have indicated that ethanol exposure modulates sigma-1 receptor activity within the Ventral Tegmental Area (VTA). Here, we explore the sub-mechanisms underlying sigma-1 receptor activity induced by HT7 (Shinmun) stimulation in behavioral alterations following acute ethanol (ETOH) administration. Methods : Male Wistar rats were investigated for pro- and anti-inflammatory markers after injection of ETOH (1 g/kg) using cytokine enzyme-linked immunosorbent assay (ELISA)s. After confirming that HT7 stimulation changed the total distance traveled in the open field test (OFT), protein changes in the Ventral tegmental area (VTA) were measured by Western blotting. The expression level of inducible nitric oxide synthase (iNOS) after administration of a sigma-1 receptor antagonist (dihydrobromide 1047; BD1047, 10 mg/kg i.p.) and Shenmen (HT7) stimulation was compared. Results : As a result, acute ETOH administration increased proinflammatory marker levels (TNF-𝛼 and IL-6). HT7 stimulation restored the total distance response after acute ethanol administration. In addition, in the VTA, the levels of a microglial marker (iNOS), sigma-1 receptor and protein kinase C, which are predicted to be involved in up- and downregulation, were restored by HT7 stimulation. In particular, HT7 stimulation modulates iNOS expression through effects similar to BD treatment. This study suggests that the stimulatory effect of HT7 may be driven by microglial activation. Conclusions : Microglial activity is regulated by sigma-1 receptor, and sigma-1 receptor activity is regulated by HT7 stimulation. Significantly, we demonstrate that HT7 stimulation ameliorates behavioral alterations induced by acute ETOH administration through microglial activation within the VTA.

This study addressed the cost structure of metallurgical plants for vanadium recovery or production, which were previously planned or implemented. Vanadium metallurgy consists of several sub-processes such as such as pretreatment, roasting, leaching, precipitation, and filtration, in order to finally produce vanadium pentoxide. Here, lots of costs should be spent for such plants, in which these costs are largely divided into CAPEX (Capital Expenditure) and OPEX (Operational Expenditure). As a result, the capacities (feed input rates) and vanadium contents are various along the target projects for this study. However, final production rates and grades of vanadium pentoxide showed relatively small differences. In addition, a noticeable correlation is found between capacities and specific operating costs, in that a steadily decreasing trend is described with a non-linear curve with around -0.3 power. Therefore, for the plant capacity below 100,000 tons per year, the specific operating cost rapidly decreases as the capacity increases, whereas the cost remains relatively stable in the range of 0.6 to 1.2 million tons per year of the capacity. From a technical perspective, effective optimization of the metallurgical process plant can be achieved by improving vanadium recovery rate in the pre-treatment and/or roasting-leaching processes. Finally, the results of this study should be updated through future research with on-going field verification and further detailed cost analysis.

Despite countries' efforts to reduce carbon emissions, carbon emissions have increased in recent decades along with energy use, of which building energy uses account for a large proportion. Energy savings are essential as a strategy to reduce carbon emissions in existing buildings. The field experiment on the roof of a building located in Seoul was designed to measure the temperature reduction effect of green roof with rainwater storage tank to reduce cooling energy consumption in summer. The results showed that the mean mean surface temperature under the green roof was 14.77 degrees lower than that of the non-green roof from 13:00 P.M. to 15:00 P.M., which would have a great effect on reducing cooling energy. From 01:00 A.M. to 03:00 A.M., the effect was 3.36 degrees, showing that tropical nights could be improved. The temperature reduction effect due to the rainwater storage system increased by 1.45 degrees during the day and decreased by 0.63 degrees at night. The storage system can be strategically utilized to reduce carbon emissions during the week when cooling energy increases significantly.
