This study aimed to examine biological and histopathological interactions of cruciferous vegetables and H. trifolii to provide basic information useful for the management of the cyst nematode. In the screening of Chinese cabbage and radish cultivars for reproduction, cyst formation (number of cysts per plant) and fecundity (number of eggs per cyst) of H. trifolii at 28 days after inoculation (DAI) were significantly higher in Chinese cabbage than radish cultivars, indicating the nematode multiplication rates were significantly higher in Chinese cabbage than radish. Among these cultivars, Geumjeong was revealed to be resistant to the nematode as nematode population was decreased with negative multiplication rate of 0.2%, contrary to other cultivars with positive multiplication rates of 4.9โ€“59.8%. Nematode penetration rates increased progressively from 2 until 10 DAI to reach penetration rates in the higher order of Chinese cabbage cv. CR, radish cv. Geumjeong and Songbaek, but initial nematode growth was similar among the cultivars examined. For histopathological characteristics, syncytial areas at 10 and 15 DAI differed in relation to the nematode reproduction on the cultivars examined, but rates of syncytial areas relative to stele areas were not in the higher order of the nematode reproduction, suggesting plant damages caused by the nematode infection may not be completely coincided with the nematode reproduction. The same biological characteristics mentioned above were examined using the selected cultivars by the soil amendment with a fertilizer of increased concentrations at intervals of 0.01% (0.00โ€“0.04%). In this study, the nematode multiplication rates were significantly higher at 0.00% and lowest at 0.02% at which plant growth were significantly higher than the other concentrations. Initial penetration rates and nematode growths differed little among the fertilizer concentrations except for 0.03% and 0.04% which inhibited greatly plant growths. All of these aspects may provide information useful for the development of the nematode control strategies.Heterodera trifolii๋Š” 2018๋…„ ๊ฐ•์›๋„ ๊ณ ๋žญ์ง€ ๋ฐฐ์ถ” ์žฌ๋ฐฐ์ง€์—์„œ ์ฒ˜์Œ ๋ถ„๋ฆฌ๋˜์—ˆ๋‹ค. 2011๋…„ ๋ณด๊ณ ๋œ H. schachtii์™€ ํ˜•ํƒœ ๋ฐ ์ฆ์ƒ์ด ์œ ์‚ฌํ•˜์—ฌ ์ด ๋‘ ์ข…์ด ํ˜ผํ•ฉํ•˜์—ฌ ํ”ผํ•ด๋ฅผ ์ž…ํ˜”์„ ๊ฒƒ์œผ๋กœ ์—ฌ๊ฒจ์ง„๋‹ค. ๋”ฐ๋ผ์„œ ๋ณธ ์—ฐ๊ตฌ๋Š” H. trifolii์— ๊ฐ์—ผ๋œ ์‹๋ฌผ์˜ ์ƒ๋ฌผํ•™์ , ๋ณ‘๋ฆฌํ•™์  ํŠน์„ฑ์„ ํŒŒ์•…ํ•˜์—ฌ ์ ์ ˆํ•œ ๊ด€๋ฆฌ ๋ฐฉ๋ฒ•์„ ๋„์ถœํ•˜๊ธฐ ์œ„ํ•ด ์‹ค์‹œํ•˜์˜€๋‹ค. ์šฐ๋ฆฌ๋‚˜๋ผ ์‹ญ์žํ™”๊ณผ ์ž‘๋ฌผ์ธ ๋ฐฐ์ถ”์™€ ๋ฌด, 5๊ฐ€์ง€ ํ’ˆ์ข…์„ ๋Œ€์ƒ์œผ๋กœ ์„ ์ถฉ ์ ‘์ข… 28์ผ ํ›„ ํ™•์ธํ•œ ์ฆ์‹๋ฅ ์€ ๋ฌด๋ณด๋‹ค ๋ฐฐ์ถ”์—์„œ ํ˜„์ €ํžˆ ๋†’์•˜๋‹ค. ๊ตฌ์ฒด์ ์œผ๋กœ, H. trifolii์˜ cyst ํ˜•์„ฑ์œจ๊ณผ ์‚ฐ๋ž€์œจ (cyst ๋‹น ์•Œ ์ˆ˜)์€ ๋ฐฐ์ถ”๊ฐ€ ๋ฌด๋ณด๋‹ค ๋†’์•˜๊ณ  ๋ถ€ํ™”์œจ์€ ๋ฌด์™€ ๋ฐฐ์ถ”์—์„œ ๋šœ๋ ทํ•œ ์ฐจ์ด๋ฅผ ๋‚˜ํƒ€๋‚ด์ง€ ์•Š์•˜์œผ๋‚˜ ์ดˆ๊ธฐ ์ ‘์ข… ์„ ์ถฉ ๋ฐ€๋„ ๋Œ€๋น„ ์ตœ์ข… ์„ ์ถฉ ๋ฐ€๋„๋Š” ๋ฐฐ์ถ”๊ฐ€ ๋ฌด๋ณด๋‹ค ํ˜„์ €ํžˆ ๋†’์•˜๋‹ค. ํ˜•์„ฑ๋œ cyst์˜ ์ˆ˜์— ๋”ฐ๋ผ ์ˆœ์„œ๋Œ€๋กœ ๋ฐฐ์ถ”์˜ CR, ๋ฌด์˜ ์†ก๋ฐฑ, ๊ธˆ์ •์„ ์„ ๋ฐœํ•˜์˜€๊ณ  2์ผ์ฐจ, 5์ผ์ฐจ ๊ทธ๋ฆฌ๊ณ  10์ผ์ฐจ ์นจ์ž…๋ฅ  ์กฐ์‚ฌ ๊ฒฐ๊ณผ, ์ดˆ๊ธฐ ์นจ์ž…๋ฅ ์€ ๋ฐฐ์ถ”๋ณด๋‹ค ๋ฌด์—์„œ ๋†’์•˜์ง€๋งŒ 10์ผ์ฐจ์— ๋ฐฐ์ถ”์—์„œ์˜ ์นจ์ž…๋ฅ ์€ ๋น ๋ฅธ ์†๋„๋กœ ์ฆ๊ฐ€ํ•˜์—ฌ ๊ฐ€์žฅ ๋†’์€ ์นจ์ž…๋ฅ ์„ ๋‚˜ํƒ€๋‚ด์—ˆ๋‹ค. ๊ทธ๋Ÿฌ๋‚˜ ์„ ์ถฉ์˜ ์นจ์ž… ์ดํ›„ ๋ฟŒ๋ฆฌ ๋‚ด ์„ ์ถฉ์˜ ์ƒ์žฅ์€ ํ’ˆ์ข… ๊ฐ„ ์œ ์˜์ ์ธ ์ฐจ์ด๊ฐ€ ์—†์—ˆ๋‹ค. ์กฐ์ง๋ณ‘๋ฆฌํ•™์  ๋ฐ˜์‘์„ ํ†ตํ•œ ํ•ฉํฌ์ฒด์˜ ๋ฐœ๋‹ฌ์„ ์กฐ์‚ฌํ•œ ๊ฒฐ๊ณผ 10์ผ์ฐจ, 15์ผ์ฐจ ๋ชจ๋‘ ์ฆ์‹๋ฅ ์ด ๊ฐ€์žฅ ๋†’์•˜๋˜ ๋ฐฐ์ถ”์˜ CR ํ’ˆ์ข…์—์„œ ๊ฐ€์žฅ ํฐ ๋ฉด์ ์˜ ํ•ฉํฌ์ฒด๋ฅผ ํ˜•์„ฑํ•˜์˜€๋‹ค. ์‹œ๊ธฐ๋ณ„ ํ•ฉํฌ์ฒด์˜ ๋ฉด์  ๋ณ€ํ™” ์กฐ์‚ฌ์—์„œ ๋ฌด์—์„œ์˜ ์„ ์ถฉ ์ฆ์‹์ด ์–ต์ œ๋จ์— ๋”ฐ๋ผ ํ•ฉํฌ์ฒด์˜ ๋ฐœ๋‹ฌ์ด ์–ต์ œ๋˜๋Š” ๊ฒƒ์„ ํ™•์ธํ•˜์—ฌ ํ•ฉํฌ์ฒด ๋ฐœ๋‹ฌ์ด ์„ ์ถฉ์˜ ์ƒ์‹๋ ฅ๊ณผ ๊ด€๋ จ์ด ์žˆ์Œ์„ ํ™•์ธํ•˜์˜€๋‹ค. ์‹๋ฌผ์˜ ๋ฐœ์œก์„ ์ด‰์ง„์‹œํ‚ค๋Š” ๋น„๋ฃŒ๋ฅผ ๋†๋„๋ณ„๋กœ ์ฒ˜๋ฆฌํ•˜์˜€์„ ๋•Œ ์‹๋ฌผ์˜ ์ง€ํ•˜๋ถ€ ์ƒ์œก์ด ๊ฐ€์žฅ ์ข‹์•˜๋˜ ๋น„๋ฃŒ์˜ ๋†๋„์—์„œ ์„ ์ถฉ์˜ cyst ํ˜•์„ฑ์œจ๊ณผ ์ˆ˜์™€ ์‚ฐ๋ž€์œจ์ด ๊ฐ€์žฅ ๋‚ฎ์•˜๊ณ  ์‚ฐ๋ž€์œจ์€ ๊ฐ€์žฅ ๋†’์€ ๋†๋„์—์„œ ์œ ์˜์ ์œผ๋กœ ๋†’์•˜๋‹ค. ๋น„๋ฃŒ ์ฒ˜๋ฆฌ ์‹œ ์„ ์ถฉ์˜ ์ดˆ๊ธฐ ์นจ์ž…๋ฅ ์€ ๋น„๋ฃŒ์˜ ๋†๋„๊ฐ€ ๋‚ฎ์•„์งˆ์ˆ˜๋ก ๋†’๊ฒŒ ๋‚˜ํƒ€๋‚ฌ์ง€๋งŒ ์ตœ๊ณ  ๋˜๋Š” ๊ทธ ๋‹ค์Œ์˜ ๋น„๋ฃŒ ๋†๋„์—์„œ๋Š” ์ดˆ๊ธฐ ์นจ์ž…๋ฅ ์ด ๋‚ฎ์„ ๋ฟ๋งŒ ์นจ์ž… ์ดํ›„ ์„ ์ถฉ์˜ ์ •์ƒ์ ์ธ ์ƒ์žฅ์„ ์–ต์ œํ•˜์—ฌ, ์ตœ์ข…์ ์ธ cyst ํ˜•์„ฑ์œจ์ด ๋‚ฎ์•„์ง€๋Š” ๊ฒฐ๊ณผ๋ฅผ ์ดˆ๋ž˜ํ•˜์˜€๋‹ค. ์ด๋Ÿฌํ•œ ์—ฐ๊ตฌ๊ฒฐ๊ณผ์—์„œ H. trifolii์˜ ์ฆ์‹์€ ํ•ฉํฌ์ฒด์˜ ๋ฐœ๋‹ฌ๊ณผ ๊ด€๋ จ์ด ์žˆ๊ณ , ๋น„๋ฃŒ์˜ ๋†๋„์— ๋”ฐ๋ฅธ ์„ ์ถฉ์˜ ์ฆ์‹, ์นจ์ž…, ์„ฑ์ˆ™์— ๋Œ€ํ•œ ์ฒ˜๋ฆฌํšจ๊ณผ๊ฐ€ ํ™•์ธ๋จ์— ๋”ฐ๋ผ H. trifolii์˜ ๋ฐฉ์ œ์ „๋žต์„ ๋„์ถœํ•˜๋Š”๋ฐ ์œ ํšจํ•œ ์ •๋ณด๋ฅผ ์ œ๊ณตํ•  ๊ฒƒ์œผ๋กœ ์ƒ๊ฐ๋œ๋‹ค.ABSTRACT โ…ฐ CONTENTS โ…ฒ LIST OF TABLES โ…ด LIST OF FIGURES โ…ต โ… .

This has the objective of investigating the immersion factors of the users to understand the behavior and psychology of them and to investigate the relationship between the game and sports based on actual sports. Also, it has referred to the flow theory of Csikszentmihayi(1990) and has performed the questionnaire analysis using the on-line community representing each sports game by setting the variables, concentration, control, challenge, feedback, objective and social interaction etc as the variables with which the user can be absorbed in. The final analysis was performed using the 251 remaining pieces excepting the 43 pieces which have been judged to be non-credible or of which the response content is insincere out of the 294 user's sport game online community user. For the data analysis, the SPSS 21.0 and the Amos 18.0 statistics program was used and the confirmative factor analysis and SEM model verification were used to verify the hypothesis of this study. According to the study result, the sports online game immersion factors was the concentration (interface), control(degree of manipulation), challenge (level of difficulty) and the social interaction which have positive effect on the sports online game. Especially, the social interaction affected the most and it was verified that as the user become absorbed more in the sports online game, the joy became higher. Thus, all the hypothesis were supported except the feedback among all the hypothesis set in this study and it was verified that as the user become more immersed in the game, the joy also became higher.

    MasterEmissions of greenhouse gases are expected to cause climate change. The main greenhouse gas is carbon dioxide and the major source of it is the combustion of fossil fuels to supply energy. Emissions can be reduced by a variety of measures, such as improving energy efficiency and developing alternative energy sources, like wind and solar power. However a rapid move away from fossil fuels is unlikely as energy supply infrastructure has a long life time, and such a move could destabilize economics. Another way to reduce emissions is to capture the CO2 that is released from fossil fuel-fired power plant and store it underground. One-third of CO2 emissions from power plant using fossil fuel. So, reduction of greenhouse gases, especially CO2, by power plant may be an effective solution for the critical issue of global warming and climate change. Oxy-PC (Pulverized Coal) combustion with CO2 recirculation has been under active investigation recently as a measure of CCS (Carbon Capture Storage). Oxy-combustion is the term for when a fossil fuel is combusted with nearly pure oxygen and recycled flue gas or CO2 and water/steam to produce a flue gas consisting essentially of CO2 and water. It may have potential as part of a system for capturing and storing CO2 as the nitrogen concentration in the flue gas is much lower than when air is used for firing. However, There are many problems about Oxy-PC combustion because of difference between Air and CO2 environment. So, It is important that understand how pulverized coal combust in O2/CO2 environment. CFD simulation is performed for the Oxy-PC test facility at Aachen University and the 0.4 MW single burner by the commercial software STAR-CD to analyze combustion characteristics for parametric variation of the major operating conditions and design variables. Different flow characteristics are partly due to a lower magnitude of the outlet velocity of oxy combustion with CO2recirculation than that of air combustion with the same mass flow rate. A higher CO2 mass fraction can increase the outlet velocity magnitude, but can cause an energy density problem
