In this study, current sewer infiltration/Inflow(I/I) computation and application method was examined about improvement and adequacy relating to the main issues raised by the field for practitioners. The results of review about infiltration calculation method were considered to be in need of improvement at 'standards of minimum sewage calculation'. Furthermore, the results of review about I/I application method were considered to be in need of improvement at 'standards of seasonal infiltration application' and 'the relative decrease in the Annual evaluation standards'. In addition, annual I/I analysis at JC County for the four years(2009~2012) in respect of operation flow and rainfall data was conducted. The result of annual infiltration analysis, compared average daily sewage generated average infiltration rate was found in 21.95 %, infiltration by unit was found in $0.31m^3/day/cm/km$ and $0.12m^3/day/day$, respectively. The result of annual inflow analysis, average rainfall - Inflow equations was found $y=5.499{\times}$($R^2$ 0.793), and the average Inflow quantity by sewer extension was predicted to $0.66m^3/mm-km$.

The taxonomic entity and morphological characteristics of Impatiens furcillata were reviewed based on the original description and the type specimen. As a result, I. furcillata, by having glabrous stems, descending and glabrous peduncles, and pinkish white flowers, is strikingly distinguishable from other taxa of Korean Impatiens. Both I. hypophylla var. koreana and I. kojeensis are treated as synonyms of I. furcillata, for their morphological characteristics, were the same as those of I. furcillata. In addition, the Korean name for I. furcillata was changed to 'Cheo-jin-mul-bong-seon' instead of 'San-mul-bong-seon'.

A comparative study of $^{131}I$-hippuran renogram, $^{131}I$-hippuran excretion test and intravenous pyelogram were performed in 61 cases of gynecological cancer. The following were the results: 1. Among 40 cases of cervix cancer showing normal excretory urography 7 cases (17.5%) were found to have unilateral or bilateral delayed excretory pattern on $^{131}I$-hippuran renogram and on the contrary only 2 cases (5.7%) showed a mild caliectatic change on excretory urography among 35 cases of gynecological cancer showing normal pattern of $^{131}I$-hippuran renogram. 2. In the group showing unilateral or bilateral delayed excretory pattern on $^{131}I$-hippuran renogram there was a reduction of $^{131}I$-hippuran excretion in the first 20 minutes, but there was no significant difference of $^{131}I$-hippuran excretion in 60 minutes compared with that of normal renogram group. 3. In the group showing unilateral non-functioning pattern of $^{131}I$-hippuran renogram in one side and normal pattern in the other side there was found to be no difference in $^{131}I$-hippuran excretion amount compared with that of normal renogram group. 4. It was evident from these experimental study that $^{131}I$-hippuran renogram was considered as a good examination method for the evaluation of obstructive uropathy, and if one side kidney was intact it might compensate for the other diseased kidney so far as to renal excretory function. It was also shown that the more severe the cancerous spread in the pelvic wall the more changes on $^{131}I$-hippuran renogram.

Gintonin, a novel, ginseng-derived G protein-coupled lysophosphatidic acid (LPA) receptor ligand, elicits $[Ca^{2+}]_i$ transients in neuronal and non-neuronal cells via pertussis toxin-sensitive and pertussis toxin-insensitive G proteins. The slowly activating delayed rectifier $K^+$ ($I_{Ks}$) channel is a cardiac $K^+$ channel composed of KCNQ1 and KCNE1 subunits. The C terminus of the KCNQ1 channel protein has two calmodulin-binding sites that are involved in regulating $I_{Ks}$ channels. In this study, we investigated the molecular mechanisms of gintonin-mediated activation of human $I_{Ks}$ channel activity by expressing human $I_{Ks}$ channels in Xenopus oocytes. We found that gintonin enhances $I_{Ks}$ channel currents in concentration- and voltage-dependent manners. The $EC_{50}$ for the $I_{Ks}$ channel was $0.05{\pm}0.01{\mu}g/ml$. Gintonin-mediated activation 1 of the $I_{Ks}$ channels was blocked by an LPA1/3 receptor antagonist, an active phospholipase C inhibitor, an $IP_3$ receptor antagonist, and the calcium chelator BAPTA. Gintonin-mediated activation of both the $I_{Ks}$ channel was also blocked by the calmodulin (CaM) blocker calmidazolium. Mutations in the KCNQ1 $[Ca^{2+}]_i$/CaM-binding IQ motif sites (S373P, W392R, or R539W)blocked the action of gintonin on $I_{Ks}$ channel. However, gintonin had no effect on hERG $K^+$ channel activity. These results show that gintonin-mediated enhancement of $I_{Ks}$ channel currents is achieved through binding of the $[Ca^{2+}]_i$/CaM complex to the C terminus of KCNQ1 subunit.

Background: Cardiac troponin I (cTnI) is a sensitive cardiac marker of myocardial injury. In normal coronary angiogram, positive cTnI values may be detected in various events such as sepsis, stroke, trauma and so on. To investigate characteristics of cTnI positive group in trauma patients, we designed this study between cTnI positive group and cTnI negative group. Method: Trauma patients who visited emergency room within 24 hours after accidents were included. Patients who had renal failure, acute coronary syndrome, sepsis, spontaneous SAH were excluded. Retrospective study of 97 trauma patients was done. We investgated ISS (injury severity score), positive cTnI, EKG abnormality, shock class, ICU admission rate and mortality. Result: In comparing with non chest trauma group, chest trauma group, whose chest AIS (Abbreviated Injury Score) is more than 3 point, had significant values in ISS, positive cTnI, EKG abnormality, shock class and ICU admission rate. Also, in non chest trauma group, we found several patients whose cTnI level was positive. When non chest trauma group was divided into two subgroups, the mortality and shock class of positive cTnI group were higher than that of negative cTnI group. When all trauma patients were divided into two groups, a positive cTnI group had higher values in ISS, shock class, ICU admission rate and mortality than that in a negative cTnI group. Conclusion: We found that cTnI were positive in patients of cardiac contusion but also in various trauma cases. In non chest trauma patients, we assumed that hypotension caused cTnI elevating. The cTnI could play a role in predicting prognosis in trauma patients.

In order to elucidate the physiological function of circulating IGF-I on muscle protein synthesis in the chicken under malnutritional conditions, we administrated recombinant chicken IGF-I using a osmotic mini pump to fasted young chickens and measured the rate of muscle protein synthesis and plasma metabolite. The pumps delivered IGF-I at the rate of $22{\mu}g/d\{300{\mu}g{\cdot}(kg\;body\;weight{\cdot}d)^{-1}\}$. Fractional rate of protein synthesis in the muscle was measured using a large dose injection of L-[$2,6-^3H$]phenylalanine. Constant infusion of chicken IGF-I did not affect plasma glucose level. Significant interaction between dietary treatment and IGF-I infusion was observed in plasma NEFA and total cholesterol concentrations. When chicks were fasted, IGF-I infusion decreased plasma NEFA and total cholesterol concentrations. On the other hand, IGF-I administration did not affect plasma levels of both metabolites. Fasting reduced plasma triglyceride concentration significantly. IGF-I infusion also decreased the level of plasma triglyceride. Plasma IGF-I concentration of young chickens was halved by fasting for 1 d. IGF-I infusion using an osmotic minipump for 1 d increased plasma IGF-I concentration in fasted chicks to the level of fed chicks. Fasting decreased body weight and the loss of body weight was significantly ameliorated by IGF-I infusion. There was a significant interaction between dietary treatment and IGF-I infusion in the fractional rate of breast muscle protein synthesis. There was no effect of IGF-I infusion on muscle protein synthesis in fed chicks. Muscle protein synthesis reduced by fasting was ameliorated by IGF-I infusion, but did not reach to the level of fed control. Muscle weight of fasted chicks infused with IGF-I was similar to fasted birds without IGF-I infusion, which suggests that muscle protein degradation would be increased by IGF-I infusion as well as protein synthesis in fasted chicks.

In this paper we describe a prototype Control Rod Control System(CRCS). The CRCS controls the motion of the full length rod drive mechanisms in response to signals from the Reactor Operator and the Reactor Control System. Each mechanism belongs to either Shutdown Banks or Control Banks. The CRCS also provides information regarding the rod motion, rod position, and the status of the Rod Control System. The prototype CRCS will be used to obtain the requirements for detailed design of a full-scale CRCS.

The role of peroxiredoxin (Prx) I as an erythrocyte antioxidant defense in red blood cells (RBCs) is controversial. Here we investigated the function of Prx I by using Prx $I^{-/-}$ and Prx I/$II^{-/-}$ mice. Prx $I^{-/-}$ mice exhibited a normal blood profile. However, Prx I/$II^{-/-}$ mice showed more significantly increased Heinz body formation as compared with Prx $II^{-/-}$ mice. The clearance rate of Heinz body-containing RBCs in Prx $I^{-/-}$ mice decreased significantly through the treatment of aniline hydrochloride (AH) compared with wild-type mice. Prx I deficiency decreased the phagocytic capacity of macrophage in clearing Heinz body-containing RBCs. Our data demonstrate that Prx I deficiency did not cause hemolytic anemia, but showed that further increased hemolytic anemia symptoms in Prx $II^{-/-}$ mice by attenuating phagocytic capacity of macrophage in oxidative stress damaged RBCs, suggesting a novel role of Prx I in phagocytosis of macrophage.

Purpose: To determine the role of Insulin-like Growth Factor-I (IGF-I) in the regulation of Vascular Endothelial Growth Factor (VEGF) expression in MG-63 cells and then to find the mechanism b which this regulation occurs. Materials and methods: MG-63 cells were grown to confluence in 60-mm dishes. To determine the effects of IGF-I on expression of VEGF mRNA according to time and concentration, the cells were treated with 10 nM IGF-I, following isolation of total RNA and Northern blot analysis after 1, 2, 4, 8, 12, 24 hours and after 2 hours of treatment with 0.5, 2, 10, 25, 50 nM IGF-I respectively, isolation of total RNA and Northern blot analysis were followed. To determine the mechanism of action of IGF-I, inhibitors such as hydroxyurea $(76.1\;{\mu}g/ml)$, actinomycin D $(2.5\;{\mu}g/ml)$, cycloheximide $(10\;{\mu}g/ml)$ were added 1 hour after treatment of 10 nM IGF-I. Results: 1. the expression of VEGF mRNA was increased with treatment of IGF-I. 2. The expression of VEGF mRNA was increased according to time-and concentration dependent manner of IGF-I. 3. The effect of IGF-I was decreased by hydroxyuera, actinomycin D, but not by cycloheximide. Conclusion: IGF-I regulate the expression of VEGF mRNA in the level of DNA synthesis and transcription. These results could suggest that IGF-I plays an important role in angiogenesis in the process of new bone formation and remodeling.
