  • The projection approximation subspace tracking (PAST) is one of the attractive subspace tracking algorithms, because it estimates the signal subspace adaptively and continuously. Furthermore, the computational complexity is relatively low. However, the algorithm still has room for improvement in the subspace estimation accuracy. FE-PAST (Forward-Backward PAST) is one of the results from the improvement studies. In this paper, we propose a new algorithm to improve the orthogonality of the FB-PAST (Forward-Backward PAST).

  • The up-to-moment dataset is built by combining the past dataset and the recent dataset. The proposal is to compute association rules in real time. This study proposed the model, $EM_{past'}$ and algorithm that is sensitive to time. It can be utilized in real time by applying partitioned combination law after dividing the past dataset into(k-1). Also, we suggested $EM^{ES}_{past}$ applying the exponential smoothing method to $EM^p_{past'}$ When the association rules of $EM_{past'}\;EM^w_{past'\;and\;EM^{ES}_{past}$ were compared, The simulation results showed that $EM^{ES}_{past}$ is most accurate for testing dataset than $EM_{past}$ and $EM^w_{past}$ in huge dataset.

  • This paper examines the relationship between architecture of the past and architecture of the present, and suggest that necessity to reinterpret it in the context of today's architecture, rather than accepting the past architecture as its historical meaning. Such a condition, however, the architecture of the past works in another ways not in a historical ways that is generally perceived, and this paper suggest another interpretations in the meaning of past architecture and what significance it has.

  • This paper will examine the way Philip Larkin as a modern poet views unfavorable but inescapable past experiences with ambivalent attitudes. Larkin has written poems which concern the matters of time, aging, and death. Out of these related themes, the past has offered one major subject for Larkin's poems. Those poems on his personal experiences, coming out of his deep interest in the past and in the relationship the past has with his present and future life, reveal much of the poet's personality. Because of Larkin's conflicting attitudes towards past life, however, the poems about his past create both ambivalence and attraction in the readers' minds. The unusual restraint of emotion and conflict revealed in the poems about past life render rare modern lyrics that are unlike exuberant romantic poems.

A Semantics of Sequence of Tense without a Sequence-of-tense Rule

  • I argue in this paper that the sequence of tense (SOT) phenomenon can be accounted for without positing a SOT rule, focusing on the contrast between the past under-past sentences which lead to ambiguity and those sentences which do not. The different interpreta- tion of past under past sentences depends on whether the stative or then non-stative predicates occur in the complement clauses in the propositional attitude verbs. Based on this, I also argue that the embedded past tense does not contribute to the seman- tics past tense in the complement clause. Instead, it is due to the occurrence of the stative or non-stative predicates in the complement clauses. The stative predicates are associated with the temporal precedence or the overlap relation, whereas the non-stative predicates the precedence relation only. This fact triggers the contrast in past- under- past sentences.(Korea University)

Mediating Effects of the Factors on the Relationships between Customers' Past Behavior and Intention to Voice at Western Restaurant in Suncheon City (순천시지역 서양음식점에 대한 고객들의 과거행동과 불평행동의도의 관계를 매개하는 요인들의 효과 평가)

  • The purpose of this study was to examine the mediating role of attitude, subjective norm, and perceived behavioral control on the relationships between past behavior and customers' intention to engage in voice of dissatisfaction responses. Results of the study demonstrated that the inclusion of past behavior improved the predictability of the voice of dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by mediator. In the contests of voice behavior, the effect of past behavior on intention was not mediated by attitude and perceived behavioral control. Meanwhile, subjective norm mediated the relationship between past behavior and the intention to engage in voice behavior.

  • This paper provides a corpus study on subjunctives in Korean in a way of comparative semantics. The whole arguments of this paper are bolstered by distributional evidence taken from naturally occurring bitexts (i.e. a bilingual corpus), in which one sentence in a language is aligned with one translation in the other language. Since previous studies regard past tense morphology as the main component to express irrealis and uncertainty, this paper accordingly checks out whether the past tense morpheme (e/a)ss in Korean is also responsible for conveying the meaning of subjunctives. My finding is that the past tense morpheme (e/a)ss is a sufficient condition for forming subjunctives in Korean. The current corpus study verifies that the past tense morpheme is not obligatorily used in present conditional counterfactuals in Korean, unlike English. Yet, if (e/a)ss is used and the antecedent denotes a present situation, the conditional sentence can only be interpreted as conveying counterfactuality. On the other hand, wish constructions in Korean, irrespective of the semantic tense, often contain the past tense morpheme. Hence, this work substantiates Iatridou (2000)'s theory of 'fake past tense' is applicable to Korean subjunctives. The present corpus study, additionally, reveals that a conditional marker telamyen is a component of expressing past counterfactuals in Korean.

  • The purpose of this study was to examine the mediating role of attitude, subjective norm, and perceived behavioral control on the relationships between past behavior and customers' intention to engage in exit of dissatisfaction responses. Results of the study demonstrated that the past behavior significantly improved the predictability of the voice of dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by mediator. In the contests of exit behavior, the effect of past behavior on intention to exit was mediated by attitude, subjective norm and perceived behavioral control.

  • The purpose of this study was to examine the mediating role of attitude, subjective norm, and perceived behavioral control on the relationships between past behavior and customers' intention to engage in negative word-of-mouth communication of dissatisfaction responses. Results of the study demonstrated that the inclusion of past behavior improved the predictability of the negative word-of-mouth communication of dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by the mediator. In the contests of negative word-of-mouth communication, the effect of past behavior on intention was partially mediated by attitude, subjective norm and perceived behavioral control.
