The present study, focusing on the stress-shift constructions, examines the tendency of young children to give wrong wide scope interpretation in language acquisition and questions the validity of the guess pattern hypothesis argued by Grodzinsky & Reinhart (1993). According to the hypothesis, children know that they have to construct a reference-set, keep two representations in working memory, and check whether the interpretation needed in the given context justifies selection of competing reference sets, but their working memory is not big enough to hold the materials needed to complete the execution of this task. Hence they give up and resort to a guess. 1 carried out an experiment of 16 Korean children aged 3;9 to 6;2 to find out whether children have more difficulty in the interpretation of stress-shift constructions than of constructions with a nuclear stress, and therefore perform the interpretation of the former by guessing. Assuming that the tendency is caused by a deficiency in contextual computation rather than reference set computation, I try to explain it in terms of pragmatic considerations.

Berberis aristata (family Berberidaceae), known as 'Daruharidra' in Ayurvedic system of medicine, is an important medicinal plant used extensively for treating a variety of ailments in various systems of indigenous medicine. Being an important medicinal plant it is being adulterated and in the absence of any pharmacognostic information it is very difficult to check the adulteration. The present study was therefore, carried out to provide the requisite pharmacognostic details. Morphological, anatomical and phytochemical aspects of B. aristata were carried out. Diagnostic features of B. aristata root were identified and characterized from the above investigations and presented in the present communication. Some of the diagnostic features of the root drug noted from the anatomical study are patches of pericyclic fibre, pitted sclerieds, berberine containing cells and heterocyclic medullary rays. HPTLC analysis showed three distinct bands of which berberine was identified as the major constituents. The $R_f$. value of other bands was also calculated.

In this paper, RF-ID system is used in gateless fare collection for the subway system. This enables passengers to go in and out of stations without any actions specifically for fare collection, such as carrying out from the purse at the gate, throwing tickets into gate machines or moving RF-ID cards near to the card readers. Card check zone system might extract fare from two or more cards that one person carries.

In the present study SEAM (Shear Energy Augmented Membrane) elements have been devel-oped. Maintaining the numerical efficiency of conventional membrane elements the effect of out-of-plane deformation (transverse shear deformation) has been incorporated for the purpose of computational stabilization without introducing additional degrees of freedom. Computations are carried out for the deep drawings of square cup to check the validity and the effectiveness of proposed SEAM elements. The computational results are compared with both the existing results. And the effects of process variables like initial sheet thickness punch & die round and clearance are checked

In this study, the repetitive loading-unloading tensile tests with AZ31B magnesium sheet metal have been conducted under various elevated temperatures to check out how the Young's moduli of the sheets evolve during the plastic deformation. The loading-unloading tests have been carried out at every 1% of strain increment. With the tested results, some damage parameters of magnesium sheets based on the Lemaitre's continuum damage theory could be calculated at room temperature, $100^{\circ}C$, $150^{\circ}C$, $200^{\circ}C$ and $250^{\circ}C$. It has been shown that the critical damage parameters obtained in all temperature conditions are within the range of 0.12 to 0.18.

Since the inauguration of WTO system has made borderless competition across the countries, many government should try to find out the harmonious policy paradigm for the check and balance between the globalization and localization. The government procurement market has been considered as one of this kinds of difficult tasks for the local small and medium companies. Many governments should lift the paradigm of the government procurement market toward the conditionally open competitive market. The paper is aimed to find out the sustainable governance of the government procurement policies to protect the local companies. Based on the many international cases, including the Chille-Korea FTA, the paper concludes the sustainable governance of the policies should be focused on the equitability and transparency.

For structural engineers, design of pile cap causes difficulties since design of this member is not specifically addressed by codes. In general, pile cap is considered as deep beam and designed for shear and moment at specified critical section. This is called as traditional section method. However, many international design codes suggest the application of strut tie method for better design of this member. In this paper, a brief application of strut tie method to the design check of pile cap structure designed by section method is presented. Unlike well known pile cap with single column, the example pile cap has two columns. In order to find out proper load path under various load condition, three dimensional finite element method was carried out. The result indicates that provided reinforcement by traditional section method has sufficient capacity to meet the design requirements.

This study presents development of a multi-way high speed pipe cutting machine to improve production rate of pipe cut pans. In this paper, structural and modal analysis for the developed machine is carried out to check safety of the machine design. The analysis is carried out by FEM simulation using the commercial software, CATIA V5. The machine is modeled by placing proper shell and solid finite elements. The final results of analysis are applied to the design of multi-way high speed pipe cutting machine and the machine is successfully developed.

Construction companies in Korea have shown interest in BIM (Building Information Modeling) even if late, adopted it, and applied it to several projects. But, it is hard to figure out the status of BIM implementation. Thus, this study is to figure out the status of BIM implementation in Korea by surveying major construction companies in Korea and comparing with similar surveys abroad. The survey result shows that only 11 companies in Korean construction industry adopted BIM. The clash check (73%) was mostly used among various BIM functions and other functions were used less than 30%. As of 2008, only 8 construction companies have used BIM in 27 projects and thus, Korean companies are in the BIM introduction period. Therefore, successful introduction of BIM is required by benchmarking the BIM introduction process of overseas construction industries

This study examined the symptoms of temporomandibular disorder and the relationship with the psychological character using Symptom Check List-90-Revision (SCL-90-R). The self-administered questionnaire survey was implemented from March 1, 2014 to June 30, 2014 targeting 294 University Students in Daejeon and Gangwon area aged 20-31 years old (Men 140 persons, Women 54 persons). The data showed that the teeth grinding and the unilateral chewing out of corrupt practices in the mouth in relation to the use of the lower jaw showed a significant correlation (p<0.01) with the depth of symptoms of temporomandibular disorder, as the result of the simple psychodiagnosis inspection (SCL-90-R), and a significant correlation (p<0.05) with the depth of symptoms of temporomandibular disorder in the item excluding phobic anxiety (PHOB). The somatization (SOM) criteria out of individual psychological characteristic appeared to have the significant plus (+) effect on the depth of symptoms of temporomandibular disorder as a result of implementing multiple regression analysis by controlling the individual characteristic variables to check the influence of the psychological character of the study object on the symptom of temporomandibular disorder.
