In order to investigate optimum and marginal sowing date of foxtail millet, proso millet and sorghum in middle area (Anseong, Gyeonggi province) of korea, four levels of sowing date [(May 15(1st), June 6(2th), June 26(3th), July 13(4th)] with mulching and non-mulching were treated in this experiment. We used three crops of foxtail millet, proso millet and sorghum with four varieties of Samdachal, Samdamae, Kyeongkwan1, Hwanggeumjo in foxtail millet, Leebaekchal, Manhongchal, Hwangsilchal, Hwanggeumgijang in proso millet and Nampungchal, Hwanggeumchal, DS202, Moktaksusu in sorghum achieved from RDA. In culm length, sowing date of June 26 was the highest in all varieties of foxtail millet, proso millet and sorghum. Sowing date of May 15 showed the highest ear length in foxtail and proso millet, whereas the highest ear length was obtained from sowing date of June 26 in sorghum. In numbers of leaf, sowing date of May 15 showed the highest in all three crops of foxtail millet, proso millet and sorghum. Days from sowing to heading date were reduced in Samdamae, Kyeongkwan1 and Samdachal as sowing date was late. In Hwanggeumjo it was reduced from the sowing date from May 15 to June 26, but it was same days was taken between June 26 and July 13 sowing date. Days from sowing to heading date of four varieties in proso millet were reduced as sowing date was late. Days from sowing to heading date in sorghum were reduced as sowing date was late, whereas it was increased the $4^{th}$ sowing date of July 13. There were no significant differences in growth and yield characteristics between mulching and non-mulching in four varieties of foxtail millet, proso millet and sorghum with four varieties. The highest grain numbers per panicle, 1000 grain weight and yield per 10a were obtained from sowing date of June 26 in four varieties of foxtail millet, proso millet and sorghum. In sowing date of July 13, all varieties of foxtail millet, proso millet and sorghum were not able to be ripened because of late sowing except Hwnaggeumjo, Manhongchal and Hwanggeumgijang.

Interleukin-17A (IL-17A) is a multifunctional cytokine which plays a crucial role in the initiation and progression of cancer. To date, several studies have investigated associations between IL-17A -197G>A (rs2275913) polymorphism and digestive cancer risk, but the results remain conflicting. We here aimed to confirm the role of this single nucleotide polymorphism (SNP) in susceptibility to digestive cancer through a systemic review and meta-analysis. Ten eligible case-control studies were identified by searching electronic databases, involving 3,087 cases and 3,815 controls. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were used to estimate the strength of the association. The results of overall analyses indicated that the variant A allele was associated with an increased risk of digestive cancer (AA vs GG: OR=1.51, 95%CI=1.18-1.93; AA vs GG+GA: OR=1.45, 95%CI=1.12-1.87; A vs G: OR=1.21, 95%CI=1.05-1.39). In subgroup analysis stratified by specific cancer type, elevated risk among studies of gastric cancer was found (AA vs GG: OR=1.68, 95%CI=1.24-2.28; AA vs GG+GA: OR=1.62, 95%CI=1.16-2.26; A vs G: OR=1.23, 95%CI=1.04-1.46). According to ethnicity, there was evidence in the Asian populations for an association between this polymorphism and cancer risk (GA vs GG: OR=1.19, 95%CI=1.05-1.36; AA vs GG: OR=1.56, 95%CI=1.15-2.12; AA+GA vs GG: OR=1.28, 95%CI=1.13-1.44; AA vs GG+GA: OR=1.42, 95%CI=1.01-2.00; A vs G: OR=1.24, 95%CI=1.08-1.44), while in the Caucasian populations an association was found in the recessive model (AA vs GG+GA: OR=1.62, 95%CI=1.17-2.24). In conclusion, the results of this meta-analysis suggest that the IL-17A -197G>A polymorphism contributes to an increased risk of human digestive cancer, both in the Asian and Caucasian populations and especially for gastric cancer.

This study aims to identify the effects: quality of chest compressions, height and weight of pregnant women cardiac arrest while lying $30^{\circ}$ inclined to the left has on the quality of chest compressions administered by 119 EMT. For the purpose of this study, 62 members of 119 EMTs in M, N, S, Y cities and G cities of J province agreed to join in the test and the test was conducted from June 15 to 16 in 2015. Two mannequins (Resusci Anne$^{(R)}$) were used for the study and the chest compression process was recorded with the use of the Laerdal PC Skill Reporting System$^{(R)}$. As a result, it was discovered that for patients with a $30^{\circ}$ left inclination, who were below 170 cm in height and 65 kg in weight, the proper frequency and depth of compression were unsatisfactory. With this in mind, training programs and instruments that can improve the quality of chest compressions depending on a person's (patient's) height and weight should be developed.

Purpose : Limited information is available on experiences of intravenous iron treatment in children. In this study, iron sucrose was administered intravenously to determine its effect, the factors predicting outcome, and safety in children on chronic dialysis. Methods : Twenty-one children whose serum ferritin levels were less than 100 ng/mL or transferrin saturations (TSAT) were less than 20% were enrolled. In 12 children on peritoneal dialysis (PD), the drug was infused intravenously as 200 mg/$m^2$ ($\leq$200 mg) at week 0, 2, 4, and 6. In 9 children on hemodialysis (HD), it was given intravenously as 8 weekly doses of 3 mg/kg ($\leq$100 mg) through week 0-7. Results : After treatment, serum ferritin levels increased significantly in both groups, and TSAT rose significantly in PD group. However, hemoglobin level did not rise significantly in both groups. Children with baseline hemoglobin less than 10 g/dL or baseline TSAT less than 20% showed significantly higher rise of hemoglobin after intravenous iron treatment. To the contrary, those with higher baseline hemoglobin and TSAT levels displayed higher rise in serum ferritin after the treatment. Although no serious adverse event occurred, TSAT levels exceeding 50% were noted in 6 patients in PD group. Conclusion : This suggests that 3 mg/kg/week of intravenous iron sucrose can be used safely in children on chronic HD, but 200 mg/$m^2$ every other week may incur excessive TSAT level in some patients on chronic PD.

Motor imagery based Brain-computer Interface(BCI), which has recently attracted attention, is the technique for decoding the user's voluntary motor intention using Electroencephalography(EEG). For classifying the motor imagery, event-related desynchronization(ERD), which is the phenomenon of EEG voltage drop at sensorimotor area in ${\mu}$-band(8-13Hz), has been generally used but this method are not free from the performance degradation of the BCI system because EEG has low spatial resolution and shows different ERD-appearing band according to users. Common spatial pattern(CSP) was proposed to solve the low spatial resolution problem but it has a disadvantage of being very sensitive to frequency-band selection. Discriminative filter bank common spatial pattern(DFBCSP) tried to solve the frequency-band selection problem by using the Fisher ratio of the averaged EEG signal power and establishing discriminative filter bank(DFB) which only includes the feature frequency-band. However, we found that DFB might not include the proper filters showing the spatial pattern of ERD. To solve this problem, we apply a band-selection process using CSP feature vectors and linear discriminant analysis to DFBCSP instead of the averaged EEG signal power. The filter selection results and the classification accuracies of the existing and the proposed methods show that the CSP feature is more effective than signal power feature.

In order to find out the environment vulnerable to cigarette fire in which smoldering fire grows into flame fire, a cigarette combustion test and numerical analysis were performed using fallen leaves of P. densiflora and Q. variabilis. Tests were repeated five times on 2,304 conditions with four cases of fuel moisture content, six cases of velocity, two cases of cigaret location against direction of the wind, three cases of cigaret location against fallen leaves, two species of thickness of cigaret, two cases of slope conditions and two cases of fragileness of fallen leaves. Cigaret fire's flammability to the fallen leaves was monitored by analyzing heat transfer process using CFD (Computational Fluid Dynamic) under the most optimal condition through an ignition test on 2,304 conditions. The result of a cigaret fire ignition test for fallen leaves, found ignition in 197 conditions out of 2,304 conditions representing 8.6% while 13 conditions representing approximately 0.6% saw ignition across five repeated tests. The result of CFD analysis, the temperature of the bottom of fallen leaves was reached on self-ignition and pilot-ignition temperature.
