This paper compares sequential and non-sequential verbal conjunctions in Korean, English, and Japanese by looking at how sequential verbal conjunction is treated in each language. It frist reviews verbal conjunctions in Korean, where sequential conjunction is treated as subordination and non-sequential conjunction is treated as coordination, and looks at verbal conjunctions in English and Japanese to see whether or not sequential conjunction in those languages is subordination. According to Oh (2010), sequential and non-sequential conjunctions in Korean behave quite differently with respect to the tense and negation in the final conjunct. Also, Cho (1995, 2005) and Kwon (2004) show that syntactic operations such as extraction and scrambling clearly distinguish sequential conjunction from non-sequential conjunction. The purpose of this paper is to see how sequential and non-sequential conjunctions are analyzed in English and Japanese and to compare those languages with Korean, especially focusing on whether or not sequential conjunctions in English and Japanese are treated as subordination. For this purpose, I first investigate how tense and negation, which provided crucial evidence for concluding that Korean sequential conjunction is subordination, is interpreted in sequential and non-sequential verbal conjunctions in English and Japanese. Also, I investigate the syntactic properties of sequential and non-sequential conjunctions with respect to syntactic operations such as extraction and scrambling in those languages. The results of the investigation show that in Japanese, which is considered typologically similar to Korean, the sequential conjunction is a case of subordination, while in English, which is considered typologically different from Korean, both sequential and non-sequential conjunctions are treated as coordination.

This paper shows the tonal patterns of English conjunctive utterances produced by Korean speakers of English, presenting that Korean speakers realize either the H - phrase tone or the H% boundary tone at the phrase-final part of the conjunctive utterances. Based on Pierrehumbert & Hirschberg's (1990) claim that either H- or H% tone indicates that a phrase is related to the following one, Korean speakers seem to produce the satisfactory patterns of edge tones in conjunctive sentences. In the experiment, we made up conjunctive sentences including both coordinate conjunctions such as and, but, or, and so and subordinate conjunctions like if, when and though. We varied the stimuli according to the existence of a comma and the lengths of connecting words and phrases. We also divided the subjects into two levels of English proficiency based on their English written test scores to see if Korean speakers' performance ability of edge tones is related with their general competence of English. Results show that Korean speakers produced 84% of the H- phrase tone in intermediate phrases and H-L% and L-H% boundary tones in intonational phrases. Also, coordinate and subordinate conjunctions show little difference in their tonal contours, and the existence of a comma or the lengths of connecting words and phrases do not affect Korean speakers' production of the H- phrasal tone and the H% boundary tone. This may suggest that pitch accents, rather than edge tones, should be put more focus on in teaching English intonation in Korea as much work has already shown that Korean speakers have serious problem with producing pitch accents in speaking English.

This paper, based on Krifka (2001), is about the interpretation of quantifiers in questions. I have argued that quantification into question acts is possible for universal quantifiers, as these quantifiers are based on conjunction, an operation that is defined for speech acts. This explains the restriction to universal quantifiers, which are generalized conjunctions. I have developed a type system in which quantification into question acts can be described. I have argued that expressions that scope out of speech acts must be topic, which explains a number of additional observations. I have also discussed embedded questions, which, depending on the embedding verb, may allow for quantification into questions.

Quite recently, it has been suggested that the interaction of the solar wind with Mercury results in the variation in the solar wind velocity in the Earth's neighborhood during inferior conjunctions with Mercury. This suggestion has important implications both on the plasma physics of the interplanetary space and on the space weather forecast. In this study we have attempted to answer a question of whether the claim is properly tested. We confirm that there are indeed ups and downs in the profile of the solar wind velocity measured at the distance of 1 AU from the Sun. However, the characteristic attribute of the variation in the solar wind velocity during the inferior conjunctions with Mercury is found to be insensitive to the phase of the solar cycles, contrary to an earlier suggestion. We have found that the cases of the superior conjunctions with Mercury and of even randomly chosen data sets rather result in similar features. Cases of Venus are also examined, where it is found that the ups and downs with a period of ~ 10 to 15 days can be also seen. We conclude, therefore, that those variations in the solar wind velocity turn out to be a part of random fluctuations and have nothing to do with the relative position of inner planets. At least, one should conclude that the solar wind velocity is not a proper observable modulated by inner planets at the distance of 1 AU from the Sun in the Earth's neighborhood during inferior conjunctions.

Most if not all research articles published in journals require the author to write an abstract regardless of academic field. However, abstract writing in English is a highly specialized genre on its own. In this light, the purpose of this study is to investigate differences in journal article abstracts written in English by Korean and native English scholars. 90 research paper abstracts written in English by Korean national scholars, US-educated Korean scholars and native English scholars were compared according to rhetorical organization. A generalized rhetorical scheme was used in analysis which was based on Graetz (1985) and Swales (1990): Background-Purpose-Method-Result-Conclusion. In addition, the use of conjunctions as a cohesive device was analyzed based on the categories proposed by Halliday and Hasan (1976). Analyses of the research paper abstracts showed that the majority of the abstracts included the purpose, method and result components. However, while approximately 70 percent of native English writers used research background in the abstract, only 26 percent of Korean national scholars did so. Regarding the use of conjunctions, Korean-national scholars overused and inappropriately used additive and temporal conjunctions. The US-educated Korean scholars showed similar patterns to the native English speakers. The findings obtained here imply that there is a need to provide academic writing instruction of abstracts to non-native scholars.

This research examined the development in Korean children of the comprehension of complex sentences. The relative difficulty in comprehension of the temporal conjunctions "before" and "after" was investigated. The order of mention, contextual support, and syntactic appearance was controlled. The role of cognitive strategies and developmental changes in the comprehension of these conjunction was included in this study. Subjects were 90 preschool children between 3 and 5 years of age. The task was a sentence-picture matching problem having 3 types of sentences combining temporally with "before" or "after". The results were that developmental changes in comprehension of the temporal conjunctions "before' and "after" in Korean children depended on the order of mention, contextual support, and such syntactic factors as the position of the subject of the sentence. The importance of the consistency in the occurrence of events and the order of mention in the acquisition of complex sentences among Korean children is similar to the acquisition of complex sentences in other languages.

The purpose of this study is to devise a new method for examining the readabilities of textbooks and to compare the readabilities of elementary school science textbooks. Third and sixth grade science textbooks were compared in terms of word, sentence, and paragraph in this study. In the word analyses, criterion suggested by Kim (2003) who classified about 238,000 words into seven categories according to their educational importances was adopted. In this study, the words from 3rd and 6th grade science textbooks were classified into four categories, and then the kinds and frequencies of words in each category were investigated. In the sentence analyses, sentences were classified either a simple sentence or a compound/complex sentence, and the ratios of each type were calculated. The average number of words in a sentence was also calculated in the sentence analyses. The ratios of conjunctions and demonstratives were examined in the paragraph analyses. The results indicated that both the kinds and frequencies of words in 3rd grade science textbook were smaller than those of 6th grade one. However, both science textbooks were similar in the distributions of words across the four categories. The ratio of simple sentences in 3rd grade science textbook was higher than that of 6th grade one, and the length of a sentence in 3rd grade science textbook was also shorter than that of 6th grade one. Both the ratios of conjunctions and demonstratives in 3rd grade science textbook were lower than those of 6th grade one.

S of Chon buk N. Unv. It is empirically known that, in concentrated conjunctions lubricated with O/W emulsions, only the oil is entrained to form elastohydrodynamic films. In the present work, this phenomenon is studied experimentally and the result is compared with a theory Which employes a starved lubrication concept. The experiment is conducted in a four roller machine with 0/W emulsions of varying concentration of oil, i.e. beef tallow, in which the film thickness is determined by detecting the rate of X-ray transmission through the conjunction. Excellent agreement is found between the experimental and the theoretical results.

The purpose of this paper is to analyze the semantic ambiguity of coordination connected by 'and' in English and show a clear explanation for the meaning of the sentence. Two sentences which are connected by 'and' can be divided into the symmetric conjunction and the asymmetric conjunction according to its meaning. Especially, in order to explain the different meaning in the asymmetric conjunctions, we introduce the theory of presupposition and entailment, which provides the solution to the ambiguity in meaning. It can be said that presupposition and entailment can logically explain the meaning of natural language.
