A Circulating Fluidized-Bed (CFB) with an internal nozzle and a partition wall was proposed. The technique of fluidization is related to operations first used commercially in the fields of metallurgical and mechanical engineering such as the heat treatment of metals and power station combustors. In the modified CFB, an internal nozzle and a partition wall were additionally set in the main bed. This cold mode CFB apparatus made of acrylic resin; the main bed is 1,500mm high and 100mm in the inner diameter, the internal nozzle is 130mm high and 10mm in the inner diameter, and the partition wall is 7mm thick and 100mm in the diameter. Glass beads of $89{\mu}m$ in the mean diameter were employed as bed materials.

Microglia are the confined immune cells of the central nervous system (CNS). In response to injury or infection, microglia readily become activated and release proinflammatory mediators that are believed to contribute to microglia-mediated neurodegeneration. In the present study, inflammation was induced in the immortalized murine microglial cell line BV-2 by lipopolysaccharide (LPS) treatment. We firstly performed phosphoproteomics analysis and phosphoinositide lipidomics analysis with LPS activated microglia in order to compare phosphorylation patterns in active and inactive microglia and to detect the pattern of changes in phosphoinositide regulation upon activation of microglia. Mass spectrometry analysis of the phosphoproteome of the LPS treatment group compared to that of the untreated control group revealed a notable increase in the diversity of cellular phosphorylation upon LPS treatment. Additionally, a lipidomics analysis detected significant increases in the amounts of phosphoinositide species in the LPS treatment. This investigation could provide an insight for understanding molecular mechanisms underlying microglia-mediated neurodegenerative diseases.

The effects of cadmium on the catalase activity and isozyme patterns under light and dark conditions of rice(Oryza sativa L. cv. Dongjin) seedlings were examined. Cadmium treatment resulted in the notable enhancement of $H_2O_2$ contents in the seedling roots and leaves under light and dark conditions. The catalase isozyme patterns in the roots were different from those in the leaves, showing tissue-specific expression of the enzyme. Moreover, the expression patterns of catalase isozymes in the green seedling roots were different from those in the etiolated seedling roots following cadmium treatment. The increase of total catalase activity was about 16 times at 1 mM cadmium and marked inductions of the isozyme CAT1 and CAT2 contributed to this increase in the green seedling roots. On the other hand, in the etiolated seedling roots, total catalase activity was lower than that of control at 0.5 and 1 mM cadmium, even though catalase activity increased about 3 times at 0.1 mM cadmium. The 3 fold increase of total catalase activity was mainly due to the increase of CAT1, CAT3 and CAT4 at 0.1 mM cadmium. However, treatment with higher concentrations of cadmium decreased the activity of CAT2 and CAT4 in the etiolated roots. In the leaves, the catalase existed as three isozymes; one cationic isozyme CATc, one neutral isozyme CATn and one anionic isozyme CAT1 in the control. The isozyme patterns and total activities remained unaffected by cadmium under light and dark conditions in the seedling leaves. Taken together, it seems that cadmium-induced changes of catalase might be regulated by light in the roots, but not in the leaves.

In this study, we investigated the tide-induced flow patterns near the ocean outfall of the Jeju and Bomok Wastewater Treatment Plants (WTP) in Jeju Island by using measurements of Acoustic Doppler Current Meter (ADCP) and a numerical experiment with inserting passive tracer into a regional ocean model. In late spring of 2018, the ADCP measurements showed that tidal currents dominate the flow patterns as compared to the non-tidal components in the outfall regions. According to harmonic analysis, the dominant type of tides is mixed of diurnal and semi-diurnal but predominantly semidiurnal, showing stronger oscillations in the Jeju WTP than those in the Bomok WTP. The tidal currents oscillate parallel to the isobath in both regions, but the rotating direction is different each other: an anti-clockwise direction in the Jeju WTP and a clockwise in the Bomok WTP. Of particular interest is the finding that the residual current mainly flows toward the coastline across the isobath, especially at the outfall of the Bomok WTP. Our model successfully captures the features of tidal currents observed near the outfall in both regions and indicates possibly high persistent pollutant accumulation along the coasts of Bomok.

Purpose: To conduct a nationwide academic hospital patterns of the practice status and principles of radiotherapy for prostate cancer. The survey will help develop the framework of a database of Korean in Patterns of Case Study. Materials and Methods: A questionnaire about radiation treatment status and principles was sent to radiation oncologists in charge of prostate cancer treatment at thirteen academic hospitals in Korea. The data was analyzed to find treatment principles among the radiation oncologists when treating prostate cancer. Results: The number of patients with prostate cancer and treated with radiation ranged from 60 to 150 per academic hospital in Seoul City and 10 to 15 outside of Seoul City in 2006. The primary diagnostic methods of prostate cancer included the ultrasound guided biopsy on 6 to 12 prostate sites(mean=9), followed by magnetic resonance imaging and a whole body bone scan. Internal and external immobilizations were used in 61.5% and 76.9%, respectively, with diverse radiation targets. Whole pelvis radiation therapy(dose ranging from 45.0 to 50.4 Gy) was performed in 76.9%, followed by the irradiation of seminal vesicles($54.0{\sim}73.8$ Gy) in 92.3%. The definitive radiotherapy doses were increased as a function of risk group, but the range of radiation doses was wide(60.0 to 78.5 Gy). Intensity modulated radiation therapy using doses greater than 70 Gy, were performed in 53.8% of academic hospitals. In addition, the simultaneous intra-factional boost(SIB) technique was used in three hospitals; however, the target volume and radiation dose were diverse. Radiation therapy to biochemical recurrence after a radical prostatectomy was performed in 84.6%; however, the radiation dose was variable and the radiation field ranged from whole pelvis to prostate bed. Conclusion: The results of this study suggest that a nationwide Korean Patterns of Care Study is necessary for the recommendation of radiation therapy guidelines of prostate cancer.

We report on a simple method for inducing physical and chemical property-gradient on nanoimprinted patterns by intensity-regulated plasma treatment under caved sample stage. As for the size gradient, a line pattern having a linewidth of 294.9 nm was etched to have gradually varying width from 277.4 nm to 147.9 nm. Modified pattern was proven to be adaptable to replica stamp for reversal patterning. To investigate the wettability gradient, imprinted nanopatterns were coated with fluoroalkylsilane to increase the hydrophobicity, and the surface was modified to have gradually varying wettability from hydrophobic to hydrophilic (contact angle was ${\sim}160^{\circ}$ to ${\sim}5^{\circ}$ on a single chip). This method is expected to be applicable to the selective adsorption of biological entities and hydrodynamic manipulation of liquid droplets for the pumpless microfluidics.

Although imprinted nanopatterns of organic polymer can be modified by the heat treatment [1], it generally requires high process temperatures and is material-dependent since the heat-induced mass loss of the organic polymer is greatly affected by its chemical characteristics. When oxygen is added during the annealing process, one can reduce the process temperature as well as the dependence of the materials. With the oxygen, line width reduction of a polymer (SU-8) patterns could be accomplished at temperature of as low as $250^{\circ}C$ which was not possible in the heat only process. This oxidative line width reduction can be dramatically promoted with the introduction of oxygen plasma. The oxygen plasma, with its highly-reactive oxygen species, vigorously etches away the organic materials, proven to be extremely effective line with reduction method. It is, however, very hard to control the extent and homogeneity of the etching, particularly of very fine patterns. Here, we report an effective and reliable line width reduction method of imprinted nanopatterns by combined plasma and heat treatment. The merits of this process include the reduction of process temperature, time and material-dependence.
