We compared the Load transfer area of the composite column rechargeable through FEM in this study. We compared by the method of comparative analysis of the Abaqus program. Load transfer is easy to position the stud in the same transmission with the load direction, and the stud is to be arranged densely in the FEM is KBC2009 and KBC2013. We serve as resources for establishing a non-diaphragm type filled composite column standard through shear connectors in Load transfer area with this result.

The purpose of this study is to evaluate the seismic performance of unreinforced masonry(URM) building more accurately. For that, the nonlinear hysteresis models of preceding research did not validate for dynamic analysis. Therefore, in this study, we compared the results of the shaking table test and dynamic analysis. As a result, nonlinear hysteresis models are expected to be applicable.

Recently climate change have increased consumption of building heating and cooling energy. Furthermore, the study on energy reduction is important. Especially the outer covering of the building has been made of concrete more than 70%. The study is to evaluate durability of concrete using insulation performance improvement materials.

Tensile stress and strain of rear by shock wave become the cause of rear side scabbing of concrete subjected to high-velocity impact. Improvement of flexural and tensile performance by fiber reinforcement has great effect on the suppression of the rear scabbing.

In this study, local fracture of concrete was evaluated through high-velocity impact test. As results, increase of bending tension performance by fiber reinforcement did not affect penetration depth Control, but it decreased rear side fracture thickness and diameter. Therefore, it was observed that fiber reinforcement decreases scabbing limit thickness.

A new system to ensure fire resistance of high strength concrete column in high-rise building with an permanent formwork made of insulation materials has been being studied. In this study, the lateral pressure safety performance of concrete column member using newly develope permanent formwork was estimated.

In this study, impact of high-velocity projectile by mixing steel fiber, polyamide, nylon, polyethylene fiber which have different shape and properties respectively. Scabbing is restrained because of micro-crack caused by the shock wave offset effect and energy dispersive of synthetic fibers are mixed populations.

The purpose of this study is to investigate the field application of cold-mixed recycled asphalt using cementless binder.

Based on the study of current status for domestic port facility management system, it was used to collect information for building the ocean & port facility integrated management system.

Fossil fuel combustion generates large amount of green house gas and it was considered major emission source causingglobal warming. For reducing green house gas, renewable energy resources have been emerged as an alternative energy.Among those resources, waste has been considered major resource as one of renewable energy, but it has been not utilizedsufficiently. In Korea, there are lots of efforts to utilize sewage sludge as one of renewable energy resources due to wasteto energy project of government. In this paper, sewage sludge was utilized as main fuel in order to recover heat energysource using oxy-fuel combustion in 30KWth circulating fluidized bed (CFB) pilot plant. Firstly, basic characteristics ofsewage sludge were analyzed and fuel feed rate was calculated by stoichiometry oxygen demand. For producing 30kwthermal energy in pilot plant, the feeding rate of sewage sludge was calculated as 13kg/hr. In oxy-fuel combustion, oxygeninjection rate was ranged from 21% to 40%. Fluidized material was more suitably circulated in which the rate of U/Umfwas calculated as 8 at 800oC. Secondly, Temperature and pressure gradients in circulation fluidized bed were comparedin case of oxy and air combustion. Temperature gradients was more uniformly depicted in case of 25% oxygen injectionwhen the value of excess oxygen was injected as 1.37. Combustion efficiency was greatest at the condition of 25% oxygeninjection rate. Also, the flue gas temperature was the highest at the condition of 25% oxygen injection rate. Lastly,combustion efficiency was presented in case of oxy and air combustion. Combustion efficiency was increased to 99.39%in case of 25% oxygen injection rate. In flue-gas composition from oxy-fuel combustion, nitrogen oxide was ranged from47ppm to 73ppm, and sulfur dioxide was ranged from 460ppm to 645ppm.

Flavonols as a major kind of plant secondary metabolites are known for health-promoting compounds in onions (Allium cepa L.). The objectives of this study are to determine profiles of flavonol glycosides in different 75 onion accessions. A total of five flavonols (quercetin 3,4'- diglucoside, Q34'diG; quercetin 3-glucoside, Q3G; quercetin 4'-glucoside, Q4'G; isorhamnetin 4'-glucoside, I4'G; quercetin, Q) were identified from onion accessions. In positive ion mode using LC-ESI-MS, individual flavonols were confirmed from one and two glycosylation binding with aglycone such as quercetin and isorhamnetin. Total flavonol contents were distributed in white onion (range of 0.18-6.47 mg/g DW) and purple onion accessions (range of 2.39-6.47 mg/g), respectively. The mean of flavonol contents in purple onion (4.41 mg/g) showed 1.4-fold higher than white onion (3.23 mg/g). The Q34'diG and Q4'G were considered as the major compounds of flavonol glycosides in onion accessions.

Kenaf (Hibiscus cannabinus L.) was recognized as a potential source of forage. But the domestic cultivation techniques are not set standards yet. So we tested the basic culture techniques during 2012~2013 for getting a high yield and good grade forage production system. The best seeding method for mechanized planting (corn planter used) was hill seeding with 20×20 cm seeding distance. When we treated hill seeding with 20×20 cm, the yield what we could get was 13,641 kg/10a and it was 32% more than that of conventional practice hill seeding with 20×30 cm seeding distance. The proper seeding date for getting high yield was May 1. In May 1, the yield per 10a was reached 13,423 kg, and it was 30% more than that of seeding at May 30. More over the crude protein content which was important factor for determinating forage nutritive value was 12.7% and it was higher 1.8% (relatively 16.5% high) than that of May 30 seeding. The most effective herbicide for kenaf was Fluazipof-p-butyl. It’s herbicidal rate was 97% and phyto-toxicity was less than 5%. Regional adaptability for Jeollabuk-Do including Imsil Gun, Kochang Gun and Sunchang Gun were identified that the stable cultivation were possible in these area with average yield 12,400 kg/10a and it was about 1.7 times as compared to corn harvest.

Fresh edible sweet corns demand relatively short period to harvest fresh ears, which can allow farmers to make a choice sweet corns for various cropping systems. For this reason, we were to find the optimum planting date of late-planted sweet corns to sell fresh ears in the autumn linked to cropping system with winter crops, investigating yield and properties of marketable fresh ears and growth traits of sweet corns (cv. 'Godangok' and cv. 'Guseulok') depending on planting dates such as 10 July, 20 July, and 30 July in Suwon 2012 and 2013, respectively. The 20 July-planted sweet corns showed the most fresh ear yield. However, the 10 July-planted and the 30 July-planted had 32% less yield caused by consecutive rainfall from 10 July through 20 July, and 15% less yield due to low air temperature during ripening than the 20 July-planted, respectively. The 10 and 20 July-planted sweet corns had average 140g of a fresh ear weight and 15% heavier ear than the 30 July-planted. For the July-planted sweet corns, silking days after planting (r=-0.80**), and harvesting days after silking (r=-0.97**) and planting (r=-0.91**) were highly negatively correlated with daily mean air temperature during the period, resulting in it takes 1,100 growing degree days (GDD) to harvest fresh ears from the July-planted sweet corns. The fresh ears of the 20 July-planted sweet corns are able to be harvested by early October. Therefore it will be a good choice for the cropping system based on winter vegetable cash crops such as temperate garlic and onion with medium or late maturity. Among three planting dates 20 July-planted sweet corns had the best field performance in every year considering fresh ear yield, ear size, and stability to grow.
