Rolling Circle Amplification as Isothermal Gene Amplification in Molecular Diagnostics
구남인,김동은 한국바이오칩학회 2016 BioChip Journal Vol.10 No.4
Rolling circle amplification (RCA) developed in the mid-1990s has been widely used as an efficient isothermal DNA amplification process for molecular diagnosis. This enzymatic process amplifies target DNA sequences with high fidelity and specificity by using the strand displacing DNA polymerases. The product of RCA is long single-stranded DNA that contains tandem repeat of target sequence. Isothermal reaction amplification condition of RCA has an advantage over conventional polymerase chain reaction, because no temperature cycling devices are needed for RCA. Thus, RCA is suitable tool for point-of-care detection of target nucleic acids as well as facile detection of target genes. Combined with various detection methods, RCA could amplify and detect femtomolar scale of target nucleic acids with a specificity of one or two base discrimination. Herein, RCA technology is reviewed with an emphasis on molecular diagnosis of microRNAs, infectious pathogens, and point mutations.

Prunus × yedoensis is a representative tree species in residential areas often used as a street tree or park tree, with its popularity due to splendid flowers in the spring. We investigated plant growth, photosynthesis, chlorophyll, and carotenoid concentrations of Prunus yedoensis at 400ml/pot, 1,000ml/pot, and 2,000ml/pot Irrigation treatments. Overall growth indices such as tree height, diameter at root collar (DRC), and total dry weight could be ranked in the decreasing order "2,000ml/pot > 1,000ml/pot > 400ml/pot.". However, 2,000ml/pot featured decreased photosynthesis and total chlorophyll carotenoid contents than 1,000ml/pot treatment after July. And also, The 1,000ml/pot treatment showed relatively high photosynthetic activity and chlorophyll contents. These results suggested that the cultivation of Prunus yedoensis under 1,000ml/pot Irrigation treatment(soil water contents 25~35%) showed the best condition in growth.

유명 옹호인과 광고상품의 조화도가 광고효과에 미치는 영향에 관한 기존 연구에서 가설모형의 적합도가 상대적으로 낮게 나타난 원인을 광고상품과 유명 옹호인의 선정의 제한점 때문인 것으로 볼 수 있다. 따라서 광고상품을 상품유형별로 다양하게 선정하고 유명 옹호인의 각 속성의 영향이 고르게 반영되도록 유명 옹호인을 선정하여 실험을 실시하였다. 그 결과, 본 연구에서 제시한 가설 모형이 전체집단에서 매우 적합한 것으로, 각 상품유형별로 대체로 적합한 것으로 나타나서 상품유형과 유명 옹호인의 영향이 고르게 반영될 경구 가설 모형이 매우 타당한 것으로 나타났다. 각 변인들간의 인과관계에서는 전체집단에서 유사성이 조화도에 미치는 영향이 유의미하지 않았으며, 상품집단별로는 일부 인과관계가 유의미하지 않게 나타났다. The important role of the degree of match-up between celebrity endorser and advertised product was not spotlighted. That’s the mediating role between celebrity endorser’s attributes and advertising effectiveness. Recently, the hypothetical model on the degree of match-up was proposed and tested by Nam(2001). But the hypothetical model wasn’t perfectly supported because of the limitation in research method. Then, the following hypotheses were formulated and tested. 1. The hypothetical model on the impact of the degree of match-up between celebrity endorser and advertised product on advertising effectiveness will be valid in total group and respective product groups. 2. The causal relationships in the hypothetical model on the impact of the degree of match-up between celebrity endorser and advertised product on advertising effectiveness will be significant in total group and respective product groups. In order to test these hypotheses, an experiment was conducted for 462 university students. The obtained data were analyzed by using LISREL. As the results, Hypothesis I was supported. Hypothesis Ⅱ was partially supported. Based on the above results of hypotheses testing, therefore, the following conclusion was drawn from this study: (1) the hypothetical model on the impact of the degree of match-up between celebrity endorser and advertised product on advertising effectiveness is valid in total group and respective product groups: (2) the causal relationships in the hypothetical model on the impact of the degree of match-up between celebrity endorser and advertised product on advertising effectiveness are largely significant in total group and partially significant in respective product groups.
인터넷 이용자의 인터넷 공신력 인식이 전자상거래 행위에 미치는 영향

이 연구는 인터넷에서 제공되는 구매관련 정보에 대한 공신력의 차이가 인터넷을 통한 구매행위의 양을 예측하는 중요한 선행변인걸 것이라는 가정을 실증적으로 검증해본 연구이다. 인터넷의 공신력에 대한 인식은 사회문화적 상황에 따라 달라지는 것으로 예측할 수 있다. 사회적 상황의 차이가 인터넷 공신력과 인터넷을 통한 구매행위에 미치는 영향의 중요성에도 불구하고, 인터넷 공신력 인식에 관한 대부분의 연구는 주로 미국의 인터넷의 이용자에 대해 제한적으로 이루어졌다. 본 연구는 이러한 제한점을 벗어나 사회적 상황의 영향을 실증적으로 살펴보기 위해 508명의 미국 인터넷 이용자와 434명의 한국 인터넷 이용자를 대상으로 설문조사를 실시하였다. 조사결과 사회문화적 배경에서 서로 다른 특성을 갖는 두 나라의 인터넷 이용자들은 인터넷 공신력에 대한 인식에서도 차이를 보였다. 또한 미국과 한국, 어느 나라에서나 인터넷에 대한 공신력 인식이 인터넷을 통한 고매행위의 경험과 이후의 구매의도에 영향을 미치는 것으로 나타났다. This study starts with such assumption that credibility perception of Internet commercial information can be viewed as an antecedent condition which predicts the amount of e-commerce transactions. The state(or level) of Internet credibility perceptions appears to vary according co given socio-cultural contexts. Despite the importance of different social contexts, most of Internet credibility perception research has so far been limited coward US Internet users. This research conducted a survey with 508 Internet users in US and 434 Internet Users in Korea. The results of the survey showed the effect of Internet credibility perceptions on the e-commerce transaction experience and intention in both countries. They were discussed from the disparity in socio-cultural contexts . In particular, this research revealed how different Internet credibility perceptions are between Internet users in Korea and US. Other main issues are also discussed.
