The complete chloroplast genome of Polygonatum falcatum (Asparagaceae)
최태영,윤세현,이수랑 한국식물분류학회 2022 식물 분류학회지 Vol.52 No.1
Polygonatum falcatum is a perennial herb distributed in East Asia. We determined the characteristics of the complete chloroplast genome in P. falcatum for the first time, with a de novo assembly strategy. The chloroplast genome was 154,579bp in length harboring 87 protein coding genes, 38 tRNA genes and eight rRNA genes. It exhibits typical quadripartite structure comprising a large single-copy (LSC) (83,528bp), a small single-copy (SSC) (18,457bp) and a pair of inverted repeats (IRs) (26,297bp). Phylogenetic analysis of 16 chloroplast genomes from Asparagaceae reveals that the genus Polygonatum is a monophyletic group and that P. falcatum is clustered together with the congener, P. odoratum.

Cassel(1916)에 의해서 최초로 제시된 구매력평가설은 국제외환시장에서의 환율변동을 규명하기 위하여 환율을 물가수준에 연계시켜 설명함으로써 획기적인 외환이론으로서 갈채를 받았다. 그러나 Cassel 이후 많은 학자들의 연구에도 불구하고 구매력평가설의 유효성에 관해서는 학자들간에 일치된 의견을 도출해 내기가 힘들었다. 본 논문은 Citi-Database로부터 추출된 최근 데이타(기간 1975-1985)를 이용하여 미국 영국 일본 한국을 대상으로 환율변동을 두가지 물가지수(소비자물가지수 도매물가지수)에 각각 대응시켜 구매력평가설의 유효성을 재조명해 보고자 한다. 분석결과는 구매력평가설의 이론과 실제사이에는 상당한 괴리가 있음을 보여주었으며, 이는 대다수 학자들의 연구결과와도 일치되었다. 상대적구매력평가설은 절대적구매평가설에 비해 현실설명력이 더 높았으며, 아울러 분석기간(일년 오년 십년)이 짧을수록 유효성이 더 높았다. 즉, 본고에서 이용된 모델은 일년이 오년보다, 오년이 십년보다 더욱 설명력이 높았다.
전자상거래가 보험회사의 영업형태에 미치는 영향에 관한 연구

The advent of electronic commerce is changing the paradigm of insurance industry. Also the market share of cyber insurance product tends to increase gradually due to its advantages such as low price and convenience over the traditional insurance goods. As a result, the insurance industry will be affected by the electronic commerce in many respects. First, the traditional supply and value chain of insurance industry will be dissolved. Second, Disinter-remediation, or the dynamic process of disintermediation and reintermediation, will occur. Third, competition between traditional insurance companies and virtual insurance companies will be intensified. Fourth, The trading volume of business-to-business insurance transactions will exceed that of business-to-consumer insurance transactions. Finally, consumers will gain more power.
On the Effect of a Pilot Coding Education Support System for Complex Problem Solving Tasks
전인성,송기상 한국인터넷방송통신학회 2018 Journal of Advanced Smart Convergence Vol.7 No.4
In the programming education, there is a great need of a teaching support system that can support the learner in the programming process regardless of the computer language due to instructor’s difficulty of checking the progress of learners in real-time. Its importance is especially important in lower grade coding classes such as in K-12 education because they are not used to coding and so simple problems can be regarded as complex problems. For this, a pilot coding education support system based on Levenshtein distance algorithm which shows learners’ progress to given solution in real-time was developed in order to help learners to solve complex problems easily, and the learners’ motivation and self-efficacy was measured for estimating the usefulness of developed system targeting elementary school students. When the learners use the developed system, it was found that a statistically significant difference appears in the sub-factors of learning motivation compared with traditional class teaching environments. Among the sub-factors of self-efficacy, the efficacy dimension showed statistically significant difference too.
