  • A combined experimental-computational study of a double edge-notched stone specimen subjected to tensile loading is presented. In the experimental part, the load-deformation response and the displacement field around the crack tip are recorded. An Electronic Speckle Pattern Interferometer (ESPI) is used to obtain the local displacement field. The experimental results are used to validate a numerical model for the description of fracture using finite elements. The numerical model uses displacement discontinuities to model cracks. At the discontinuity, a plasticity-based cohesive zone model is applied for monotonic loading and a combined damage-plasticity cohesive zone model is used for cyclic loading. Both local and global results from the numerical simulations are compared with experimental data. It is shown that local measurements add important information for the validation of the numerical model. Consequently, the numerical models are enhanced in order to correctly capture the experimentally observed behaviour.

  • Within the field of Korean linguistics, it has been observed that subjective adjectival predicate constructions are characteristic of imposing 'coreference constraint' on the higher and lower subjects, while evidential -te- constructions imposing 'non-coreference constraint' on them. I interpret these constraints as dependency constraints between higher and lower judge-sensitive semantic predicates, and investigate the interactions among subjective adjectival predicates, evidential -te-, and modal -keyss- in Korean. The paper ultimately argues for the necessity to add a new indexical element, the judge of evaluation(Lasersohn 2005, Stephenson 2007), to the traditional set of indices that were confined to the world and the time.

  • In the traditional Locality approach to floating numeral quantifiers in Korean and Japanese, two subject positions have been identified for external merge, one in Spec, vP and the other in Spec, TP (Saito 1985, Miyagawa 1989, 2013, Miyagawa and Arikawa 2007, etc.). In this paper, I show that the two external merger positions of the subject are unnecessary in the grammar of Korean and Japanese. Rather, by accepting the minimalist assumption of the VP-Internal Subject Hypothesis (Kitagawa 1986, Sportiche 1988, Koopman and Sportiche 1991), we are better able to explain a variety of bewildering phenomena that arise in scrambling contexts of FNQ-constructions.

  • In the event of fire, the tendency of over­buildings and high­building resulted from the concentration in population in cities causes great losses of human lives and property. Man is able to prevent fire itself from taking place on his own efforts. One of fire preventions at high­buildings is to Survey the environmental situations around the constructions from the beginning, and when the construction is going on, it is indispensable to install appropriate water­proof dampers with all sorts of equipments. Hence, lots of the owner's investment of the buildings in fire prevention facilities is necessary and, so is constructions in agreement with every regulations.

  • The construction market has gradually become complexity, variety and specialization, and then owner's requirements about quality has become various. In order to solve the problem such as stated above, advanced constructions in United Kingdom, Japan and United States have introduced warranty contract which is warranted to quality and performance for need of owner in determined term to ensure the quality of construction since 1960s. However, the interior of a country encounter another problem result from defects liability what indefiniteness of defects standard, excess responsibility period, social recognition of be identical fraudulent work and defects, and contract with ascendancy of owners. etc, so builders concerned more excess defects liability than the quality of construction. The purpose of this study is to analysis of warranty contract in order to solve the problem such as stated above.

  • This paper argues that various kinds of displaced structures in English should be licensed by a more explicitly formulated type of rule schema in order to deal with what is called weak connectivity in English. This paper claims that the filler and the gap site cannot maintain the total identity of features but a partial overlap since the two positions need to obey the structural forces that come from occupying respective positions. One such case is the missing object construction where the subject fillers and the object gaps are to observe requirements that are imposed on the respective positions. Others include passive constructions and topicalized structures. In this paper, it is argued that the feature discrepancy comes from the different syntactic positions in which the fillers are assumed to be located before and after displacement. In order to capture this type of mismatch, syntactically relevant features are handled separately from the semantically motivated features in order to deal with the syntactically imposed requirements.

Silent Verbs in Northern Mandarin: A Silence Neither Gaps Nor Emptiness Can Fill

  • This paper reanalyzes examples with missing verbs. Northern Mandarin rejects argument nominal phrases after a silent verb, as well as silent verbs inside islands. These restrictions suggest a grammatical process which silences verbs. I propose that these restrictions are the result of VP-topicalization followed by ellipsis. This analysis accounts for the island sensitivity of these constructions: since VP-topicalization feeds ellipsis, constructions with elided VPs are not derivable from configurations where movement is impossible. Also, to avoid topicalization along with the VP, the argument must move out of VP; the subsequent topicalization of the VP containing the argument's trace would then give rise to a configuration where that trace c-commands the moved-out DP. Adjuncts do not pose a problem because they are located outside of that smallest VP-shell. The data presented here are accommodated by neither of Tang's (2001) proposals for silent verbs (gapping and empty verbs). Instead, they provide support for a third source for silent verbs, VP-ellipsis via topicalization.

  • This paper discusses the nature of the associate NP of English there constructions and attempts to capture the underlying similarity between the associate NP in English and the nominative object in Korean. Specifically, this paper is centered on the Case property of the associate NP. As the first step, previous proposals on the case of the associate NP are critically reviewed. Through the criticism, this paper opposes to Chomsky's (1995, 2000, 2001) analysis and to Lasnik's (1999) partitive Case analysis. In particular, convincing reason for the partitive Case assignment to the associate NP, other than other cases, cannot be found. This paper, therefore, adopts a recent claim of Boeckx (2000) that the Case under consideration is nominative by Agree. His idea is extended to the analysis of the presentational expletive construction. This paper draws a conclusion that the associate NP of the presentational expletive construction has accusative by Agree. This dichotomy (or split) is also observed in the nominative object construction in Korean. In the nominative object construction, the nominative object has nominative Case by Agree, whereas the regular object has accusative by Agree.

  • Stone masonry structures are widely used around the world, but they deteriorate easily, due to low shear strength capacity. Many techniques have been developed to increase the shear strength of stone masonry constructions. The aim of this experimental study was to investigate the performance of stone masonry walls strengthened by metal connectors as an alternative shear reinforcement technique. For this purpose, three new metal connector (clamp) types were developed. The shear strength of the walls was improved by applying these clamps to stone masonry walls. Ten stone masonry walls were structurally tested in diagonal compression. Various parameters regarding the in-plane behavior of strengthening stone masonry walls, including shear strength, failure modes, maximum drift, ductility, and shear modulus, were investigated. Experimentally obtained shear strengths were confirmed by empirical equations. The results of the study suggest that the new clamps developed for the study effectively increased the levels of shear strength and ductility of masonry constructions.
