This study has examined the effect of cognitive resource on purchase intention of scarcity products according to the level of need for cognitive closure. In order to find out the effect on purchase intention for products that are presented a shopping environment is supposed, where various timing of consumer promotion reward exist, and where consumers can easily access and experience a lot of cognitive changes. the effect of how these two influences are adjusted according to the level of need for cognitive closure (NFCC). The study divide into two experiments. Research analyzes the behavioral differences of consumers for scarcity message products according to cognitive resource level with a moderating effect of NFCC. As a result of the study, Research according to the level of cognitive resource, when applied scarcity message product showed a negative effect of the cognitive resource (self-regulating resource) depletion level on the purchase intention of high-involvement product with scarcity message (Hypothesis 1). Consumers' purchase intention for limited products was higher at the non-depleted level than at the cognitive resource depletion level, and this difference was found statistically significant. Next, as a result of examining the difference according to the level of NFCC, the difference in the influence of cognitive resource level on purchase intention of scarcity products was found to be statistically significant where the NFCC was low (Hypothesis 2).

The purpose of this study was to explore the effect of need for closure on college students' problem recognition and communication behavior. Specifically, this research examined differences about situation recognitions and communication behaviors across level of need for closure factors (preference for order and structure, preference for predictability, decisiveness, discomfort with ambiguity, closed-mindeness). The results show that the participants with higher level of discomfort with ambiguity and low level of closed-mindeness are more likely to high problem recognition, constraint recognition, involvement recognition, and doing active communication behaviors.

The history of finding solutions of linear equations went back to some thousand years ago, and has been steadily developed to solve systems of higher degree polynomials. The method to eliminate variables came into use around the 17th and 18th century. This technique has been extended to the resultant theory that was laid in the 19th century by outstanding mathematicians as Euler, Sylvester, and B$\acute{e}$zout. In this paper we discuss the historical reflection about the development of solving system of polynomials. We add a special emphasis on E. B$\acute{e}$zout who gave the first account on the resultant which is a generalization of discriminant and Gauss elimination method.

본 연구는 1990년부터 2008년 사이 한국에서 발생한 공공분쟁 중 국회의 입법에 의해 종료된 공공분쟁의 전개과정을 살펴봄으로써 분쟁 종결에 있어 국회의 역할은 무엇이었는지 알아보는 것을 목적으로 한다. 이와 함께 입법에 의해 종결된 분쟁의 특징을 분석하고, 다른 분쟁과의 차이점은 무엇인지 비교해 보았다. 국회는 일반적으로 입법과 갈등해소 역할을 담당하는 데 이러한 역할에 얼마나 충실한지 입법에 의해 종료된 공공분쟁을 통해 알아보았다. 입법에 의해 종료된 60개의 분쟁을 분석하면서 나타난 중요한 특징은 입법에 의해 종료된 분쟁은 전국적으로 영향을 크게 미친 분쟁이라는 점이며 또한 분쟁의 강도가 매우 크다는 점이다. 이와 함께 무엇보다 입법을 통해 분쟁이 종료되었지만 입법에 있어 국회의 역할은 매우 미비하다는 점을 발견할 수 있었다. 입법에 의한 분쟁 종료이기에 국회의 역할이 클 것이라 기대해 보았다. 그러나 이러한 분쟁들은 높은 중요성과 함께 복잡성 띠고 있는 정책 혹은 낮은 중요성을 띠고 있는 정책과 관련이 있어 국회는 소극적 역할은 하는데 그치고 있다. 이러한 국회의 미비한 역할은 매우 실망스러운 결과로 공공 분쟁을 사전에 예방하고 분쟁이 발생한 후 커다란 갈등 없이 원활한 해결을 할 수 있도록 하기 위해서는 국회의 적극적인 역할이 기대되는 실정이다.

NaCl 첨가는 전력 소모를 줄여주는 역할을 하는 것으로 나타났고, 같은 전력량에서 NaCl의 첨가량이 증가하여 전류가 증가할수록 초기 반응속도가 증가하는 것으로 나타났으나 30분의 반응시간 후 최종 RhB 농도는 유사한 것으로 나타났다. 철 전극만을 이용하여 전기분해 반응만을 이용하는 경우보다 $H_2O_2$를 첨가하여 전기분해 + 전기 펜톤-유사 반응을 이용하는 것이 RhB의 탈색에 유리하다고 사료되었다. pH가 산성영역으로 갈수록 초기반응속도와 반응종결시간이 빨라졌으며, 97%의상의 제거율을 얻기 위해서는 pH 6이하에서, 5분 이내의 반응종결을 위해서는 pH 5이하에서 운전하여야 한다고 사료되었다.

So far, there have been studies to verify the effectiveness of creative advertising contents, but there have been few studies explaining why creative advertisement contents are effective in consumer cognitive processes. The purpose of this study is to examine the effect of creativity of ad contents on desire to postpone cognitive closure and ad attitude. Furthermore, the cause of the advertising effect of the creative advertisement contents was set as disfluency and the relationship between the related variables was verified. Research has shown that creative advertising does not directly produce positive advertising attitudes, but it also forms ad attitudes through mediating effects of disfluency. In addition, it was found that disfluency mediated the desire to postpone cognitive closure in creative advertising. In summary, this study finds that the disfluency of advertising is an important variable for enhancing the advertising effect of creative advertisement. This study verified the advertising effect of creative advertisement by connecting it with consumers' cognitive variables.

T7 RNA polymerase is a single subunit RNA polymerase able to accomplish whole transcription process without auxiliary factors. In order to study transcription elongation mechanism of phage T7 RNA polymerse, stepwise walking of RNA polymerase was established by immobilizing biotinylated DNA template with streptavidin bead, series of active and stable elongation complexes were obtained, Transcripts were radio isotope labeled at the 16thm 17th and 18th nucleotide residues so stable elongation transcription complex of T7 RNA polymerase containing 22-40 nucleotide residues could be identified. We identified the positions of stablely formed transcription elongation complexes of termination site in intrinsic hairpin-independent PTH terminator sequence through the established stepwise walking of wild-type of mutant R173C T7 RNA polymerases. The results suggest that stable elongation transcription complexes were at the site of passing PTH terminator signal by mutant R173C RNA polymerase.

T7 RNA polymerase is a single subunit RNA polymerase able to accomplish whole transcription process without auxiliary factors. T7 phage lysozyme involcing in destruction of host cell wall repress T7 transcription and affects transcription termination process. Therefore expression vector pT7lys containing T7 phage lysozyme gene was constructed and expressed. T7 phage lysozyme protein was purified to homogeneity by Ni-NTA column chromatography. Also amidase activity of the purified lysozyme was identified. In order to understand the effect of the lysozyme on the sequence specific transcription termination. T7 transcription elongation complexes at the site rrnB T1 transcription termination signal were made in the presence the lysozyme. The results shows that the transcription elongation complexes are unstable in the presence of T7 phage lysozyme.
