본 논문에서는 한국어 단어를 산출하는 과정에서 음절 내 부호화 과정을 규명하기 위해 2개의 단어번역과제 실험을 수행하였다. 한국어 산출에서 종성점화효과를 검증한 실험 1에서 종성 반복 조건과 통제조건 간에 단어번역시간에서 차이를 보이지 않았다. 반면에 실험 2에서는 11ms의 부적인 중성점화효과를 보였다. 구민모와 남기춘(2009)과 본 연구의 결과를 종합하면, 다음과 같은 결론에 도달한다: (1) 한국어 산출 어휘집에서 음절은 "음절체+종성"의 위계적인 내적 구조로 표상된다. (2) 음절 내 부호화는 음절체와 종성이 계열적인 순서로 진행된다. (3) 음절체를 구성하는 초성과 중성이 계열적인 순서로 음절구조에 삽입된다.

The success of continuous aluminum powder combustion with steam plasma is different from hydrocarbon ignition source. Ignition characteristics of aluminum powder with high temperature thermal plasma is studied with oxidizer-free environment. Experiment with argon plasma has same temperature conditions at 4500 K and particle feeding condition for previous combustion test with steam plasma and swirl combustor. The temperature of the plasma was measured using Optical Emission Spectroscopy method. Ignition characteristics were analyzed by SEM image and EDS. Aluminum powder with plasma has rapid evaporation mechanism contrast to hydrocarbon ignition source. It enhances to aluminum powder effective ignition characteristics.

This paper proposes a computational model which can simulate peculiar language phenomena observed in human lexical decision task. The model is designed to mimic major language phenomena such as frequency effect, lexical status effect, word similarity, and semantic priming effect. The experimental results show that the propose model replicated the major language phenomena and performed similar performance with that of human in LDT.

The priming task was used in order to provide an experimental evidence on whether the processing unit of Korean syllable is antibody or not. Four types of experimental conditions were made: antibody overlap condition (e.g., sumjil -> sungjik), rime overlap condition (e.g.,: hungchik -> sungjik), onset and coda overlap condition (e.g.,: saengjeok -> sungjik), and no overlap condition (e.g.,: chanmeol -> sungjik). In addition, we manipulated the letter type by type and type in order to investigate on whether different degrees of priming are there for the priming task. The result showed that only type showed significant inhibitory effects. This implicates that certain Korean word would be represented and processed by the antibody unit, and further studies are needed to know the whole pattern of Korean word recognition.

High Energy density metal powder has high melting point of oxide film. By this, the ignition source that can make a thermal effect of high-temperature during short time is needed to overcome ignition disturbance mechanism by oxide film. So effective ignition does not occurred with hydrocarbon ignitor, $H_2-O_2$ ignitor, high power laser. But steam plasma can be generate about 5000 K temperature field in short order. Because a steam plasma uses steam as the working gas, it is environmental-friendly and economical. Therefore in this study, we analyze steam plasma temperature field and radical species with optical emission spectroscopy method in order to apply steam plasma ignitor to metal combustion system and cloud particle ignition was identified in visual.

The purpose of this study is to prove double faced heterotopiatic placeness of North Korea which can be highlighted to one aspect through priming test. Korean-Americans are found to have a perception of North Korea as a closed society where political leader cult is practiced, Pyongyang as a display city. They have Christian nostalgia toward it as a place where Christianity was first introduced to. North Korea's heterotopiatic placeness is sharing the 5,000 years of history of the Korea peninsula on the one hand and being a closed dictatorship place on the other. North Korea is kept isolated and closed but has had a liminal space through the intentional open system like special economic zone. Pyongyang is the city for specific class where it shows the heterotopiatic character. Priming is found effective in Yeongbyun, a place of extreme mixtures placeness as being the hometown of the beloved Korean poet Kim So-Wol and the site of nuclear weapon experiment but Korean-Americans have not found any priming effect regarding the Geumgang mountain tour. As to the Arirang performance, a man-made landscape expressing North Korea's sense of value and ideology, priming resulted in preference. This study raises the needs for understanding North Korea as a multifaced placeness and it can purposely be emphasized and changed to contribute the two Korea's unification.

중의적인 단어를 처리하는 방법에 대한 선행연구로, 첫째 문맥에 맞는 의미가 먼저 활성화된다는 가설과 둘째, 여러 뜻 중에 상대적인 빈도에 따라 많이 쓰이는 의미가 먼저 활성화되고, 그것이 문맥과 일치하지 않는다면, 다른 관련된 의미를 찾는다는 가설이 제기되었다. 마지막으로 문맥에 상관없이 모든 의미가 활성화 된 후 문맥을 고려하여 문맥에 적절한 의미를 선택한다는 가설이 있다. 본 연구에서는 '먹을', '감을' 등과 같이 2가지 의미의 품사가 다른 중의 어절과 '쥐어', '감어' 등과 같이 어절 문맥('어')이 주어진 어절의 의미 활성화가 어떻게 다른지를 조사하였다. 본 연구의 목적을 위해 점화어휘 판단 과제를 사용하였다. 실험 1의 결과는 SOA 150ms 조건에서 점화자극어절과 관련된 의미가 품사와 관련 없이 모두 활성화되었다. SOA 1000ms 조건에서는 상대적으로 많이 쓰이는 체언의 의미는 계속 활성화 되어 있는 반면, 용언의 의미 점화량은 감소하였다. 명칭성 실어증 환자인 SDK의 경우 SOA 150ms 조건에서는 일반인과 같은 형태소 처리특성을 보였으나 1000ms 조건에서는 달랐다. 다른 명칭성 실어증 환자인 BIS과 전반성 실어증 환자인 PSB는 SOA 150ms 조건과 1000ms 조건에서 일반인과 아주 다른 양상을 보였다. 이것은 실어증 환자의 타잎에 따라 형태소의 처리나 중의적인 의미 활성화가 일반인과는 다르다는 것을 보여준다. 실험 2에서는 어절 문맥이 있는 '먹어', '쥐어', '감어' 등과 같은 어절을 사용하였다. 실험 2의 결과는 SOA 150ms 조건일 때 어절문맥의 영향으로 용언의 의미만 촉진적 점화효과가 있었고, 체언의 의미는 활성화되지 않았다. 그러나 SOA 1000ms로 지연시켰을 때는 용언뿐만 아니라 체언의 의미도 촉진적 점화효과가 있었다. 실험 1과 2의 결과는 중의적인 한국어 어절의 경우에도 모든 의미가 활성화되나 어절 문맥이 존재할 때는 어절 문맥의 제약으로 어절 문맥에 맞는 한 가지 의미만 활성화된다는 것을 암시한다. 또한 이러한 결과는 한국어 어절이 분석된 형태가 아닌 어절 형태로 심성 어휘집에 저장되어 있다는 것을 암시한다. 실어증 환자의 경우 실험 1과 마찬가지로 환자의 수준이나 종류에 따라 다양한 반응을 보여주었다.

Good and bad luck is an important factor that frequently affects human information processing. However, in spite of its significance, few studies have been done to examine how good and bad luck influences information processing and reasoning. The current research was performed to explore the effect of good and bad luck on reasoning and, for this, two experiments were conducted. In experiment 1, participants were primed with good or bad luck and were asked to make an inference for a given murder case and include as many as clues for it, while in experiment 2, participants were asked to exclude as many as clues for the same murder case. Results show that, in experiment 1, participants who were primed with good luck included more clues than those who were primed with bad luck. However, in Experiment 2, it was found that participants who were primed with bad luck excluded more clues than those who were primed with good luck. Findings from this study indicate that priming good luck enhances holistic thinking which leads to including more and excluding less clues whereas priming bad luck increases analytic thinking which leads to including less and excluding more clues. Implications of this study for inference and decision making, consumer behavior, and addict psychology are discussed.

Several HTPB/AP and HTPB/AP/HMX propellants were investigated experimentally for ignition characteristics in subatmospheric pressure. The threshold ignition pressure was 4psia for HTPB/AP composite propellant. The partial replacement of AP in HTPB/AP composite propellant by $5\sim15%$ of HMX, HNIW showed improvements in the threshold pressure was below 0.4psia. This appears to be due to the exothermic dissociation characteristics of HMX and HNIW at lower temperature $(\sim220^{\circ}C)$ than that of AP. The ignition substance B/KNO3 was coated thinly on the propellant surface for better ignition effect. As a result, ignition delay time of 15% was improved. NC is applied to $B/KNO_3$ ignition substance as a secondary binder and $NC-B/KNO-3$ suspension solution is coated to the propellant surface.
