  • Ninety genes randomly selected from tobacco whitefly (Bemisia tabaci) cDNA library was studied for selecting target gene in order to control of tobacco whitefly using TRV-VIGS vector (tobacco rattle virus-virus induced gene silencing vector) with RNAi. First of all, the occurrence of B. tabaci adult according to agro-infiltration of TRV was no significant difference. And that of TRV inserted tobacco whitefly cDNA showed a significant difference in each sample. P CV and N CV sample were more than 80% could be confirmed in 5 samples, for example, wh11, wh36, wh46, wh50 and wh71. Lastly, the occurrence of nymph and egg also showed a significant difference in each sample. That could be confirmed in 11 samples, for example, wh01, wh09, wh10, wh15, wh16, wh23, wh24, wh48, wh64 and wh66. In case of wh46, wh50 and wh71 sample could be confirmed that occurrence of B. tabaci adult was many, but occurrence of B. tabaci nymph and egg was a little. So sample showed a physioecological good effect to control of whitefly need to be investigated variation of gene expression in whitefly body using qRT-PCR through individual test.

  • This article reports a bi-directional interlanguage study designed to investigate the initial state of L2 acquisition with regard to English and Korean wh-questions. Based on the UG system in line with the minimalist theory, it was hypothesized that the L2 initial state is characterized by the most economical form of syntax in which no overt wh-movement to Spec-CP is assumed. Results of the early interlanguage study showed that 1) L1 Korean learners of L2 English predominantly produced wh-questions with the fronted wh-word, but without productive wh-movement to the Spec-CP position; and 2) L1 English learners of L2 Korean overwhelmingly produced wh-questions with the wh-word remaining in-situ. These results were interpreted as supporting the minimalist account of the L2 initial grammar in that no overt syntactic wh-movement were adopted in early interlanguages of both English and Korean regardless of the learner's L1.

  • In this paper, we discuss the relative positioning of Wh-related English prepositions in a Wh-interrogative construction within the Optimality Theory [1-2]. By employing the two key constraints such as *Prep-Str and Align which are developed for the positioning of Wh-related prepositions from Romance languages such as French and Italian [3] and for the positioning of Wh-related prepositions from the middle English prose from 1500 to 1900 [4-6], and by slightly modifying the constraint hierarchy of *Prep-STR >>Align into **PrepSTR <<>>Align, Choi argues that his new theory can properly explain the unique behaviors of English Whrelated prepositions being able to take two 'optional' operations such as pied-piping and stranding to find legitimate landing sites in a Wh-interrogative construction [7]. However, this new analysis again reveals the following critical problems: (1) Unlike the 'light' English Wh-related prepositions which can two optional operations for legitimate landing sites in a Wh-interrogative construction, 'heavy' Wh-related English prepositions are not allowed to have such two options: they take just one option of pied-piping only. Thus, (2) his argumentation based on the existing constraints and the modified constraint hierarchy is neither general enough nor proper to explain the issue of the relative positioning for all English Wh-related preposition cases. To include such exceptional syntactic property of the 'heavy' preposition cases within the Optimality Theory, we suggest a new constraint of *HPrep-STR ranked at the highest position of the constraint hierarchy to disallow a 'heavy' or multi-syllabic Wh-related English preposition to stay alone at the end of a sentence. The new final hierarchy of constraints we suggest to explain the exceptional positioning of 'heavy' Wh-related prepositions together with the other 'light' Wh-related prepositions in English Wh-interrogative construction will be as follows: *HPrep-STR>>Align<<>>*Prep-STR.

  • The aim of this paper is to examine the sentence final tonal patterns of English wh-questions through phonetic experiments, based on Intonational Phonology, and to explain the meaning of the final phrase tones of English wh-questions. Pierrehumbert and Hirschberg (1990) suggested that it is pitch accents rather than boundary tones which play a crucial role in the meaning of a sentence, and that most of the general questions have H-H% tonal patterns in the sentence final. However, they could not explain why wh-questions had final falling tonal patterns (L-L%). While Bartels (1999) suggested that L phrase tone has the meaning of 'ASSERTION' and it could be applied to the explanation of the meaning of wh-questions' final tonal patterns. However, her suggestions are only theoretical explanation without any experimental support. In this paper, based on Bartels (1999), the data was classified into the following three classes: 1) echo wh-questions, 2) reference questions, and 3) common wh-questions. Using this data, a production test by three English native speakers was conducted. The results show that reference questions and common wh-questions have L phrase tones in the sentence final at a high rate, and echo wh-questions have H phrase tones in the sentence final at a high rate.

  • This study investigates the fixed and random factors affecting response patterns of wh-scope interpretations in Gyeongsang Korean. It employed logistic mixed-effects regression models to analyze responses from 24 participants who listened to 40 pre-recorded stimuli from 40 different speakers. The stimuli consisted of an embedded wh-phrase and an interrogative ending marker, "-nkiko," thereby forming a wh-question, specifically a matrix wh-scope. Participants repeated the test three times. The study found that the prominence level of a prosodic phrase composed of an embedded verb and a complementizer was inversely related to responses with wh-questions, as demonstrated through multiple regression analysis in Yun. The test trial significantly impacted the number of responses with wh-questions, increasing from 50.3% in the first trial to 58.8% and 61.2% in subsequent trials. Examination of random subject effects revealed two main factors influencing responses: morpho-syntactic constraints and prosodic structural integrity. These two factors demonstrated the potential to be inversely weighted. Analysis of random stimulus effects suggested that the prominence level had limited effects on response patterns with each stimulus primarily eliciting one type of responses across trials.

  • This study was carried out to develop the manufacturing technique of Korean paper(Hanji) and find out new uses of machine-made Hanji produced on a a large scale by paper machine. Six kinds of Hanji were made and laminated with backpaper by acryl-based or vinyl acetate ethylene-based adhesive. Six kinds of wallpapers were made such as WH 1, WH 2-1, WH 2-2, WH 3-1, WH 3-2 and WH 4. Physical properties and quality test on the wallpapers were examined. Physical strength of the wallpapers was better than each strength of the Hanji and backpaper. It might be a roll of adhesive. And so, Production cost of the Hanji could be brought down if the Hanji was made thin to get strength not enough to cut during lamination of two papers(Hanji and backpaper). Hanji wallpapers of WH 3-1 and WH 4 are lower than a standard in sunlight resistance and WH 1 is in properties of opacity. WH 2-1, WH 2-2 and WH 3-2 were better than Korean standard in some quality tests. WH 2-2 and WH 3-2 were superior to other wallpapers as a whole. About, twenty kinds of wallpapers with surface treatment, are now being produced on the basis of these two types of wallpapers.

  • English allows conjoined wh-questions to have two different readings. The English sentence Which person does John like and Mary admire\ulcorner involves ATB movement and is understood either as single questions requiring one set of individuals that are liked by John and admired by Mary (which person x, likes (j,x) & admires (m,x)) or as coordinated wh-questions, allowing distinct individuals that John likes and Mary admires (which person x, likes (j,x) & which person y, admires (m,y)). I argue this ambiguity is explained by the two key assumptions about wh-movement in Chomsky (1995): (1) Movement is copying. (2) wh-phrases consist of a wh-element and a nominal restrictor. This yields two possible LFs for English depending on whether [Wh+nominal] or wh alone is interpreted as a variable. It is therefore natural for me to propose that number of questions understood corresponds to the number of nominal segments at LF.

  • wh-섬 구조는 내포문에 있는 의문사 구가 모문의 작용역을 갖을 수 없도록 하는 제약이다. 서울말에서 내포문 의문사 구가 모문의 작용역으로 해석할 수 없다고 알려져 있으나 의문사 억양으로 발화될 경우 모문 작용역 해석도 가능하다고 보고되었다. 청취 실험을 통하여 서울말에서 의문사 구의 모문 작용역 해석이 가능한지 알아보았다. 내포문에 '누구를'을 넣어 만든 세 종류의 의문문, 즉 부정 대명사와 내포문 작용역을 갖는 판정 의문문과 의문사 억양으로 발화된 모문 작용역 해석이 가능한 설명 의문문을 자극으로 준비하고 비교를 위해 일반 명사를 사용한 판정 의문문 문장도 함께 실험하였다. 피험자는 자극 문장을 듣고 '네/아니오'를 선택하거나 아니면 설명 의문문을 선택하도록 지시하였다. 피험자의 대답과 함께 선택에 소요된 반응 시간을 함께 기록하여 함께 분석하였다. 분석 결과 83.7%의 피험자가 모문 작용역 해석을 받아들이는 결과를 보여주었고 반응 시간에서 모문 작용역 문장에 대한 선택이 정답과 오답을 포함하여 가장 긴 소요 시간을 보여주었다. 이를 통해 서울말은 약한 wh-섬 제약이라고 할 수 있다.
