        Isolation and Characterization of b-Carotene Hydroxylase Gene in Rape (Brassica napus)

        오현정,고영환,Gyeong Lyong Jeon,Kyoung Ha So,송관정,Se Yong Lee 한국원예학회 2006 Horticulture, Environment, and Biotechnology Vol.47 No.4

        b-Carotene hydroxylase (b-CHX) is a key enzyme of the carotenoid biosynthetic pathway and catalyzes the hydroxylation of b-carotene's b-ring to produce xanthophylls, b-cryptoxanthin, zeaxanthin, violaxanthin, and neoxanthin. In this study, we have isolated and characterized a full-length cDNA clone encoding b-CHX from rape (Brassica napus cv. Halla). The cDNA clone showed high sequence homology with b-CHX genes from various plant species and encoded 304 amino acids with a predicted molecular weight of 33 kDa. The expression of b-CHX gene was examined by Northern blot analysis in different tissues. The transcript for b-CHX was detected in leaves, petals, and flower buds, showing the highest expression level in flower buds. The result of HPLC analysis revealed that petals and flower buds contained high levels of hydroxylated carotenoid forms such as violoxanthin and neoxanthin. These results suggest that the high expression of b-CHX gene in flowers and flower buds might be closely related with change of carotenoid composition in these tissues.

        수능 일본어Ⅰ의 문법 문항 분석 연구 ― 문법의 3요소를 중심으로 ―

        오현정 한국일본학회 2017 日本學報 Vol.113 No.-

        This paper presents a classification of grammar questions of Japanese Language I for the College Scholastic Ability Test following the revised 2009 curriculum into “form-centered,” “meaning-centered,” and “'pragmatics-centered,” questions and then discusses the characteristics and trend of each type of question. In the results, the “form-centered question” included the type focusing on conjugated/joint forms and the type focusing on proper forms for sentence meanings, and both types showed very low connections with the textbook. Even though the “meaning-centered question” appeared relatively commonly for the purpose of communication, many cases were not in accordance with the examples presented in the curriculum. Therefore, questions of Japanese Language I for the College Scholastic Ability Test should be composed based on the textbook, which would need the process of analyzing the grammar as suggested by the textbook. Furthermore, the grammar is composed of three elements namely “form, meaning, and pragmatics,” and proper expressions for each area should be used. In communication-centered grammar education, the information about when/how to use the relevant grammar in the actual language life is very important, so that it would be necessary to compose questions by clearly setting up evaluation items for each element to maintain the balance among the three elements of grammar. 본고에서는 2009개정교육과정에 의해 치러지고 있는 수능 일본어Ⅰ의 문법 문항을 ‘형태 중심 문항’ ‘의미 중심 문항’ ‘화용 중심 문항’으로 분류하여 각 유형별 특징과 출제 경향을 논하였다. 그 결과, ‘형태 중심 문항’은 활용형 및 접속 형태 등에 초점이 놓인 유형과 문장의 의미에 알맞은 형태에 초점이 놓인 유형이 있으며, 두 유형 모두 교과서와의 연계성이 매우 낮았다. ‘의미 중심 문항’은 의사소통 기능이 비교적 고르게 출제되고는 있으나 교육과정에서 제시한 예시문과 부합되지 않는 경우가 많았다. 이와 같은 문법 문항의 출제 경향은 지도 교사 및 학습자의 부담을 가중시킬 뿐만 아니라 교육과정과 교과서의 신뢰성을 약화시키는 결과를 초래한다. 수능 일본어Ⅰ에 출제되는 문항은 교과서를 전제로 문항이 구성되어야 하며, 이를 위해서는 교과서 제시된 문법 사항을 분석하는 과정이 필요하다. 또한, 문법은 ‘형태, 의미, 화용’의 3요소로 구성되어, 각각의 영역에 알맞은 표현을 사용해야 한다. 그러나 수능 일본어Ⅰ의 문법 문항을 보면, 의미 및 기능 중심 문항이 가장 많이 출제되며, 다음으로 형태 중심 문항이 출제되었고, 화용 중심 문항은 거의 출제되지 않고 있다. 의사소통 중심의 문법 교육에서는 실제 언어생활에서 해당 문법 사항을 언제, 어떻게 사용하는가에 관한 정보가 매우 중요하기 때문에 문법의 3요소가 균형 있게 출제될 수 있도록 요소별 평가 항목을 명확히 설정하여 문항을 구성할 필요가 있다. 교육과정은 교육 목표를 달성하기 위해 교육 내용을 체계적으로 계획・구성한 것으로, 교과서와 연계되어야 함은 당연하다. 평가 또한 이를 바탕으로 이루어져야 평가의 객관성이 보장될 수 있을 것이다.

        수단-목적 사슬 이론을 이용한 의복품질 평가과정에 관한 이론적 연구 : A Theoretical Study

        오현정,이은영 한국의류학회 1998 한국의류학회지 Vol.22 No.4

        The purpose of this study was to discover a conceptual framework and evaluation process of apparel quality by means-end chain theory. The theoretical study was conducted to find out a conceptual framework and build a hypothetical evaluation process model of apparel quality. Apparel quality was perceived associative network called a means-end chain and was evaluated in several stages. A conceptual framework of apparel quality evaluation was organized into hierarchical relationships among four different dimensions: physical attribute, physical function, instrumental performance, and expressive performance. The means-end structure linked tangible physical attributes and function to more abstract instrumental and expressive performance. A hypothetical evaluation process model linked dimensions of apparel quality to the selected means-end relationship. Different consumers had different means-end chains for the same apparel. Therefore different subjects are likely to have different evaluation paths. From this study we can suggest an evaluation process model of apparel quality.

        오현정,유연실 한국가정과학회 2001 한국가정과학회지 Vol.4 No.2

        The purposes of this study was to examine the present situation of merchandise assortment and informations in internet fashion shopping mall. Merchandise assortment dimensions were width and depth. Merchandise assortment factors for apparel were style, size, and color. Merchandise informations were investigated using price and fabric contents. The data were collected from 11 internet fashion site to investigate styles, colors, sizes, price and fabric contents. The data analysed with frequency, crosstab analysis, χ^2-test. The results were as follow: 1. Upper items(37.5%) as T, knits, shirts, and blouses were offered more style than bottom items(13.5%) as skirts, pants. 2. The 36.4% of styles offered one color. Basic color as black, white, grey, beige, ivory was 38.1%. 3. The 54.4% of merchandises carried same size. 4. Fiber contents was made up of cotton(44.2%), hemp & rayon(22.5%), and synthetic (33.3%). 5. The 75.1% of merchandise was relatively low price of below 50,000 won, the 24.9% of merchandise was rather high price of more than 50,000 won.

        Selective Attention in L1 Korean and L2 English Sentence Listening as Reflected by Word Recall

        오현정,최문홍 한국영어학회 2014 영어학 Vol.14 No.3

        In this study, we investigated second language learners’ attentional patterns in native (L1) and nonnative (L2) language processing as reflected in the grammatical and positional properties of words that they recalled after listening to a group of sentences. Ninety Korean high school students at three different L2 English proficiency levels listened to a list of unrelated sentences and then wrote down all the words that they could recall. It was found that the participants recalled nouns most frequently in both L1 and L2 sentences. The tendency was much greater in L2 listening than in L1 listening. Most notably, advanced learners were better able to recall verbs than lower-level groups while differences in the other categories were not very significant. Moreover, advanced learners tended to substitute semantically related ones for the target words, but less proficient learners more often supplied phonetically similar variants. These results provide support for the idea that L2 learners’ attentional patterns considerably vary as a function of proficiency, and so awareness raising and focused practice can facilitate their adaptation of attention required for the development of L2 listening ability.
