Previous studies reveal that in English there is no EMG evidence fur the feature tense-lax distinction. The technique of electro-myography(EMG) was used to see if the existing claim holds true, particularly in unstressed syllable. It was found that in unstressed syllable, the peak EMG amplitude from the orbicularis oris superior muscle was significantly greater in /p/ than in /b/, while in stressed syllable this difference was negligible. It was hypothesized that in stressed syllable, /p/ and /b/ may be differentiated by the EMG activities from a muscle other than the orbicularis oris superior muscle, e.g. the respiratory muscles relating to 'aspiration' or depressor anguli oris muscle. In Korean, there was a clear labial gestures for the feature tense-lax distinction. The phoneme-sensitive manifestation of stress and some possible reasons for the inter-speaker variability in the data and the variability within a given speaker were discussed.

The simple forms in English have mostly been investigated in terms of tense, especially by those who do not distinguish between tense and aspect in English. However, we often find some usages of the simple forms that do not seem to fit in any of the meanings of tense. The purpose of this paper is to find aspectual meanings out of the simple present and past forms by re-analyzing their meanings in terms of aspect. It turns out that they represent the perfective aspect seeing a situation as a whole with no beginning. middle and end. As for the controversial stative situations in the simple forms, they have been proven to show the perfective aspect, too, if we agree to see both the part and whole in state as having the same features. And syntactic evidences from the simple forms and their corresponding progressive forms compared also show that the habitual dynamic situations represent the same aspect in the simple forms.

Not fully satisfied with the treatment of the so-called two nows in Korean by Lee & Choi (2009), this article seeks to furnish the issue with a firmer ground to base on in the relevant conversation. A close comparison between now and cikum appearing in the present perfect and present tense results in the two findings that (i) a crucial difference between the two adverbs is that Korean cikum lacks English now's ability to be identified with the reference time and (ii) further, seeming differences between them are not real but in fact due to tense and aspectual discrepancies between English and Korean. Thus, it claims, contra Lee (1976) and Park (2004), that cikum is a temporal locating adverb which invariably locates the event time of a given eventuality at the utterance time. In particular, it motivates that a past-tensed sentence with cikum should be understood as holding in the recent past mainly from pragmatic inferences rather than semantic entailments.

In this article, we continue the study of tense symmetric Heyting algebras (or TSH-algebras). These algebras constitute a generalization of tense algebras. In particular, we describe a discrete duality for TSH-algebras bearing in mind the results indicated by Or lowska and Rewitzky in [E. Orlowska and I. Rewitzky, Discrete Dualities for Heyting Algebras with Operators, Fund. Inform. 81 (2007), no. 1-3, 275-295] for Heyting algebras. In addition, we introduce a propositional calculus and prove this calculus has TSH-algebras as algebraic counterpart. Finally, the duality mentioned above allowed us to show the completeness theorem for this calculus.

Although Korean stops and affricates show a three-way contrast of phonemes into lax, tense and aspirated, Korean fricatives have only two types, so-called 'lax' and tense. Considering that all the other obstruents maintain a three-way distinction but fricatives, it might be interesting to investigate whether the lax fricatives are really 'lax' in their phonetic and phonological realizations, as assumed. From an acoustic analysis, I found that Korean lax fricatives had a heavy aspiration along with a high pitch for the following vowel, being more comparable to the aspirated category. By contrast, their durational properties were found to be short, or lax-like. In other words, Korean lax fricatives are phonetically neither lax nor aspirated, but both. This dual nature of the lax fricatives takes a better account of the fact that why lax fricatives are subject to tensification, but not aspiration phonologically. Is that simply because there is no aspirated fricative in Korean? I suggest that Korean lax fricatives undergo tensification because of their being short in duration, and that they are not subject to the aspiration rule because they are indeed aspirated sounds.

This paper is the study on the automatic discrimination of the Korean alveolar stops. In Korean, it is necessary to discriminate the asperate/tense plosive for the automatic speech recognition system because we, Korean, distinguish asperate/tense plosive allphones from tense and lax plosive. In order to detect acoustic cues for automatic recognition of the [ㄲ, ㄸ, ㅃ], we have experimented the discrimination of [ㄷ,ㄸ,ㅌ]. We used temporal cues like VOT and Silence Duration, etc., and energy cues like ratio of high frequency energy and low frequency energy as the acoustic parameters. The VCV speech data where V is the 8 Simple Vowels and C is the 3 alevolar stops, are used for experiments. The 192 speech data are experimented on and the recognition rate is resulted in about 82%-95%.

This study investigates the contribution of vocalic information following the release of an initial stop to the identification of the three-way stop contrast (aspirated, lax, and tense) in Korean. Recent studies showed that there is a strong interaction between consonant types and tone. The findings raise questions concerning Korean listeners' use of tonal (or vocalic F0) variation in differentiation initial tense, lax, and aspirated stops. The above issues are addressed in the present study using a cross-splicing methodology. The overall results show that low vocalic F0 provided the most salient information for lax stops; tense and aspirated stop identification depended on a combination of VOT, F0, and H1-H2 characteristics. The perceptual dominance of F0 over VOT for lax stops is consistent with the size of the F0 difference in utterance-initial position, as well as their prominent role in Korean intonational phonology.

The temporal structure of events on the discourse level has long been of great interest in both theoretical and computational linguistics. In this paper, we offer a unified approach to the temporal relationships related to a hierarchical discourse structure. We apply the method of pronoun resolution to the interpretation of tense. It is based on an analysis within the framework of the controlled information packaging theory. A unique aspect of our account is that temporal interpretation across discourse segments in global discourse is subject to the same principles as the interpretation of global anaphora, and that there is thus no need to postulate independent principles to account for the discourse behaviour of tense. In this way, we can neatly explain the general view that tense parallels the anaphoric nature of pronouns.

본고는 현대중국어 시간부사 '증경(曾經)'과 '이경(已經)'의 관련 통사구조와 이에 상응하는 한국어 통사구조에 대한 고찰을 통하여 관련 구조 의미소 '시상(時相)(tense and aspect)' 특징을 분석하였고 두 부사의 차이점을 찾아보았다. 아울러 중한 두 언어에서 이들이 나타내는 자질의 같은 점과 다른 점을 찾아냈고 이를 통하여 분석의 타당성(Descriptive adequacy)을 확보하고 나아가 설명적 타당성(Explanatory adequacy)으로 이끌어 내고자 하였다. '증경(曾經)'은 상 범주의 하위 범주인 '과거경험상', '성사상', '과거지속상' 등 자질을 갖고 있고 시제 범주의 하위 범주인 '과저시제' '과거경험상' 등 자질을 겸하고 있기도 하다. 한국어의 '_었(았)_', '_었었_', '_적이 있_'과 대응관계를 이루고 있다. '증경(曾經)'은 하나의 통사구조에서 상과 시제 두 가지 자질을 갖고 있다. '이경(已經)'은 '완료상'과 완료상의 하위 범주인 '과거경험상', 그리고 미완료상의 하위범주인 '과거지속상' 등 자질을 갖고 있고 시제 범주의 하위 범주인 '과거시제', '현재시제', '미래시제' 등 시제 자질도 갖고 있으며 '상태의 변화' 자질도 갖고 있다. 한국어의 '_었(았)_', '_고_', '_었었_', '곧' 등과 대응관계를 이루고 있다. '증경(曾經)'과 동태조사 '과(過)'를 비교하자면 '증경(曾經)'은 상 범주와 시제 범주를 겸하고 있다지만 '과(過)'는 그 수식 범위가 술어밖에 없기에 상적 특징만 갖고 있다. 그리고 심층구조에서 '증경(曾經)'은 술어의 앞에서 술어를 포함한 술어 뒤에 출현한 조사, 목적어, 보어 모두와 통어 관계를 갖고 있지만, '과(過)'는 그 앞의 술어만 수식한다. '이경(已經)'이 '진행상' 자질을 가진 부사 '재(在)'를 수식할 수 있지만, '증경(曾經)'은 불가능하다. 중국어와 한국어 두 언어는 이렇게 시간 표현에서 많은 차이를 보이고 있다. 중국어의 '과거경험상', '성사상', '과거지속상' 등 상 자질과 '과거시제' 자질을 갖고 있는 시간부사 '증경(曾經)', 그리고 '과거경험상', '과거지속상' 등 상 자질 그리고 '과거시제', '현재시제', '미래시제' 등 시제 자질을 갖고 있는 시간부사 '이경(已經)' 등이 한국어에서는 '완료상', '지속상' 자질과 '과거시제' 자질로 대응된다는 것을 알 수 있다. 그만큼 중국어와 한국어 두 언어의 시간 체계는 서로 많은 차이를 보이고 있다. 이는 한중 두 나라 사람들의 사유 방식의 차이와 문화적인 차이에서 비롯됐을 것으로 사료된다.

This paper explores Discourse Rep-resentation Structures which can successfully describe the mental representations that discourse participants form when they hear so-called double access sentences. The syntactic, semantic and pragmatic characteristics of double access sentences are discussed. The analysis proposed in this paper, employing a modified version of the 'conditional beliefs' of Chung(1997), successfully explains the semantic and pragmatic characteristics of present or future tense in double access sentences as well as when and why the speaker should take or can be exempted from the responsibility for using present or future tense in double access sentences.
