This study was carried out to investigate the removal of nitrogen and phosphorus in municipal sewage depending on existence of biological coated media in BCM reactor. The reactor with biological coated media is the process combining $A_2/O$ process. The removal efficiencies for $COD_{Mn},\; BOD_5,\;SS$, T-N and T-P were $78\%,\;90.5\%,\;92.3\%,\;61.9\%,\;60.2\%$, respectively. The specific nitrification rate$(mgNO_3-N/gMLSS{\cdot}d)$ of Contact aeration basin was 52.2 and the specific denitrification rate$(mgNO_3N/gMLSS{\cdot}d)$ in anoxic basin was 95.1. Also, phosphorus release$(mgPO_4-P/gMLSS{\cdot}d)$ in Anaerobic basin was 71.8 and Phosphorus uptake$(mgPO_4-P/gMLSS{\cdot}d)$ in contact aeration was 27.1.
ACTH와 Picrotoxin에 의(依)한 혈당(血糖)과 혈장(血漿) Corticosterone 치(値)의 변동(變動)에 미치는 Chlordiazepoxide의 영향(影響)

Marc et al. reported that diazepam increased plasma corticosterone level and Dasgupta et al. suggested that chlordiazepoxide(CDP) supressed the adrenal response to ACTH. In this paper, the influence of CDP on the changes of blood sugar and plasma corticosterone level induced by ACTH and picrotoxin were investigated in male mice. The results obtained were summarized as follows; 1) The blood sugar and plasma corticosterone level were increased by CDP, ACTH, and picrotoxin, respectively. 2) The hyperglycemia induced by ACTH and picrotoxin were not affected by the CDP pretreatment. 3) The increase of plasma corticosterone level induced by ACTH was inhibited by the CDP pretreatment. 4) The increase of plasma corticosterone level appeared 30 minutes after picrotoxin injection was slightly enhanced, but the level of 120 minutes after picrotoxin injection was significantly inhibited by the CDP pretreatment.

Objectives: The purpose of this experiment is to understand the phosphorus removal ratio effects of iron plates per unit of surface area through the iron electrolysis system, which consists of an anoxic basin, aerobic basin, and iron precipitation apparatus. Methods: Iron electrolysis, which uses an iron precipitation reactor in anoxic and oxic basins, consisted of iron plates with total areas of 400 $cm^2$, 300 $cm^2$ and 200 $cm^2$ respectively. The FNR process was operated with a hydraulic retention time and a sludge retention time of 12 hours and three days, respectively. Wastewater used in the experiments was prepared by dissolving $KH_2PO_4$ in influent water. Results: The iron plates 400 $cm^2$ (16.6 $mA/cm^2$), 300 $cm^2$ (13.3 $mA/cm^2$) and 200 $cm^2$ (7.3 $mA/cm^2$) in surface area in the phosphorus reactor had respective phosphorus of 2.4 mg/l, 2.7 mg/l and 3.2 mg/l in the effluent and phosphorus removal respective efficiencies of 90.3%, 89.1% and 87.1%. The effluent in the reactor, where the iron plate was not used, had relatively very low phosphorus removal efficiency showing phosphorus concentration of 15.3 mg/l and a phosphorus removal efficiency about 38.3%. Phosphorus removal per ferrous was 0.472 mgP/mgFe in the iron electrolysis system where the surface area of iron was low. Phosphorus pollution load per active surface area and the phosphorus removal efficiency had an interrelation of RE = -0.27LS + 89.0 (r = 0.85). Conclusion: With larger iron plate surface area, the elution of iron concentration and phosphorus removal efficiency was higher. The removal efficiency of phosphorus has decreased by increasing the initial phosphate concentration in the iron electrodes. This shows a tendency of decreasing phosphorus removal efficiency because of decreasing of iron deposition as the phosphorus pollution load per active surface area increases.

The aim of this study was to evaluate on the removal effect of total nitrogen and phosphorus with municipal wastewater in ultrasonic nutrient removal (UNR) process using ultrasonic sludge carbon source. The removal efficiency for total nitrogen was 44.2% at biological nutrient removal (BNR) process, 50.8% at UNR process. The removal efficiency for total phosphorus was 45.6% at BNR process, 46.2% at UNR process. The removal of nitrogen was effectively influenced by ultrasonic sludge carbon source.

This is a study to improve the evenness of distribution of bonding rolls used in fabric finishing process. Bonding rolls being produced domestically have uneven pressure distribution in longitudinal direction. The pressure at the both ends of rolls are greater than that at the center. So, to ensure the uniform pressure distribution, they manufacture silicon coating of rolls with tapered shape: so called crown. But, the silicon coating is needed to be machined periodically, since it is worn out during operation. Therefore to avoid additional machining of silicon coating, optimal roll structure has been sought to make uniform pressure distribution on the roll surface. Existing roll structure has been changed with new design. Design has been performed for existing three kind of the bonding roll through finite elements structure analysis. By using the design data a company has manufactured bonding rolls installed at a multi functional finishing machine.
