This study categorizes consumers by the style of consumers' purchase behavior, and examines the differences in consumers' attitudes toward environment and pro-environmental behavior in the stage of purchase, usage, and disposal. The results of this study are summarized below: First, The style of consumers' purchase behavior can be categorized on a basis of four factors: fashioned-demonstrative consumer group focusing on fashion and demonstration effects when purchasing; rational consumer group more likely to concern price, quality, and product function; indifferent consumer group having no interest in purchasing; and fashioned-functional consumer group who values not only fashion but function. Second, the result of investigating the differences of consumers' attitudes toward environment reveals that the level of concern and awareness for environment is highest in rational consumer group, but lowest in indifferent consumer group. Also, it is higher in fashioned-functional consumer group than in fashioned-demonstrative consumer group. Lastly, the level of pro-environmental behavior in the stage of purchase, usage, and disposal is highest in rational consumer group, but lowest in indifferent consumer group. The level of pro-environmental behavior in usage stage is inactive in fashioned-demonstrative consumer group, whereas that in disposal stage is active in fashioned-functional consumer group for fashioned-demonstrative consumer group. It was so, especially in the area of not-being-a-litterbug.

This article investigates the use of distal demonstrative Hitlo in Taiwanese Southern Min (TSM) from a discourse-pragmatic perspective. The analysis is based on a 5-hour corpus of spoken data, including daily conversations, radio interviews, TV drama series, and some random examples. A total of 172 tokens of Hitlos are identified in the data. They can be divided into six categories according to their functions: firstly, exophoric usage, those Hitlos which refer to an object non-linguistically which can be identified in the immediate situation; secondly, endophoric usage, those which refer to an element textually; thirdly, referent introducing function, those which can be used to introduce a new but identifiable referent into the conversation (the referent usually has topical importance); fourthly, hedging expression, those which serve as a marker of imprecision; fifthly, a condition introducing marker, those which function as an indicator of the coming of a conditional sentence; finally, pause fillers, those which help speakers to manage speech turn or indicate the mental states In addition, an interactive function which Hitlo is found to serve will be discussed. Moreover, a grammaticalizational process involving semantic bleaching which Hitlo is probably undergoing is revealed in general. Finally, a filled demonstrative principle, stating that it may be a universal phenomenon to use demonstratives as filled pause will be proposed.

This paper investigates children's comprehension and production of demonstrative pronouns (DPs), 'zhege' (this) and 'nage' (that), in Mandarin Chinese. Subjects are children of ages three, four, five and six. Based on the results of the present experiment, children's developmental stages and the corresponding age grading are provided. Also, the present study incorporates a physical clue into the experiment. The result suggests that in the acquisition of deixis children rely highly on physical context to work out the meaning distinction. In addition, Piaget's egocentrism hypothesis and H. Clark's marking hypothesis are examined in the study. The result seems to support the egocentrism hypothesis. Subjects under the age of six do fail to shift the deictic center when they and the experimenter have a different perspective. As for the marking hypothesis, the study seems to challenge the hypothesis. The result shows that children actually performed better on the marked term 'zhege' than the unmarked member 'nage'.

This paper deals with Slavic discourse deixis comparing Russian, Polish, Czech and Bulgarian demonstrative and personal pronouns. In general, the Slavic proximal pronouns have precedence over the distal ones. Proximal pronouns, such as Russian eto, Polish to, and Bulgarian tova, are employed more frequently and widely than their distal counterparts to, tamto and onova. The distance-neutral pronoun to in Modern Czech was also a proximal pronoun in the past. These Slavic proximal and former-proximal pronouns function as a discourse deixis marker, whereas, in most other languages, the discourse deixis is mainly a function of distal or non-proximal demonstrative pronouns. However, the Russian, Polish, Czech, and Bulgarian discourse deixis differs in distal demonstrative and personal pronouns. In general, the Polish and Czech discourse deixis does not employ the distal demonstrative pronoun tamto or the personal pronoun ono. The Russian distal demonstrative pronoun to is actively used as a discourse deixis marker, and the personal pronoun ono can also be used to refer to the preceding discourse, though it is not frequent. In Bulgarian the distal demonstrative pronoun onova is rarely used to refer to a discourse, but the personal pronoun to frequently indicates a discourse that is repeatedly referred to in a text. The discourse deixis, which is a peripheral deixis and can be both deixis and anaphora, reveals different characteristics in different Slavic languages. In Russian, where all of the proximal, distal, and personal pronouns function as a discourse deixis marker, the deixis itself plays a crucial role in distinguishing these three pronouns from each other, revealing the speaker's psychological, emotional, temporal, and cognitive proximity to or distance from a given discourse. In Bulgarian, the most analytic Slavic language, the personal pronoun is used more as a discourse deixis marker to reveal the highest givenness of a discourse, and it seems that Bulgarian discourse deixis is more anaphoric than the other Slavic discourse deixis is.

This study classified consumers' behaviors of purchasing gifts, divided groups by the types of similar behaviors, and examined impacts of demographic variables, relevant variables in purchasing processes on those behaviors. Findings of this study can be summarized as follows. First, factors explaining consumers' behaviors of purchasing gifts were the tendency of demonstrative purchase, the level of placing values to the meaning of gifts, the level of altruism and rationality in the purchase of gifts, and the tendency of impulsive purchase. On the basis of these five factors, five distinct consumer groups showing similar behaviors of purchasing gifts based on the results of Cluster analysis were identified. Those groups were impulsiveㆍdemonstrative groups, impulsiveㆍnon-sincere groups, indifferent groups, non-impulsiveㆍdemonstrative groups, non-altruistic'ㆍrational groups, sincere groups, and altruisticㆍrational groups. Second, behaviors of purchasing gifts showed significant differences depending on gender, educational levels, occupational types, and women's employment status. Consumers with high education, professional occupation, high income tended to show the demonstrative purchase. Male consumers were not interested in the purchases of gifts and placed high values on the meanings of gifts. In contrast, female consumers showed rational behavior, but revealed the tendency of demonstrative in the purchase of gifts as well. Finally, behaviors of purchasing gifts were also different depending on the method of gathering consumer information, places of purchasing gifts, experiences of ordering paid wrapping gifts and the relevant costs, consumers' evaluations of the purchases of gifts, and degrees of satisfaction after the purchase of gifts. Impulsive'ㆍdemonstrative groups and non-impulsive'ㆍ demonstrative groups preferred departments as places of purchasing gifts and choose ordering paid wrapping gifts but showed dissatisfactions after purchases of gifts. Consumers who belongs to non-altruistic'ㆍrational groups, sincere groups, and altruistic'ㆍ rational groups tended to prefer local stores in their own villages as places of purchasing gifts and did not order paid wrapping gifts while showing high after the purchase of gifts.

Proof is an essential characteristic of mathematics and as such should be a key component in mathematics education. But, teaching proof in school mathematics have been unsuccessful for many students. The traditional approach to proofs stresses formal logic and rigorous proof. Thus, most students have difficulties of the concept of proof and students' experiences with proof do not seem meaningful to them. However, different views of proof were asserted in the reassessment of the foundations of mathematics and the nature of mathematical truth. These different views of justification need to be reflected in demonstrative geometry classes. The purpose of this study is to characterize the types of students' justification in demonstrative geometry classes taught using dynamic software. The types of justification can be organized into three categories : empirical justification, deductive justification, and authoritarian justification. Empirical justification are based on evidence from examples, whereas deductive justification are based logical reasoning. If we assume that a strong understanding of demonstrative geometry is shown when empirical justification and deductive justification coexist and benefit from each other, then students' justification should not only some empirical basis but also use chains of deductive reasoning. Thus, interaction between empirical and deductive justification is important. Dynamic geometry software can be used to design the approach to justification that can be successful in moving students toward meaningful justification of ideas. Interactive geometry software can connect visual and empirical justification to higher levels of geometric justification with logical arguments in formal proof.

A demonstrative operation of a membrane system with its caparity of 3,600m$^3$/d was carried out using reservoir water as raw water for the application of membrane filtration system to drinking water treatment. The operation was undertaken at a constant flux of 0.9 m$^3$/m$^2$/d for three months. Backwashing with NaClO of 3 ppm was allowed for 30 seconds every 20 minutes of filtration. Physical cleaning was introduced after 69 times of filtration/backwashing cycle with air-scrubbing and backwashing for 1 minute, and flushing for 2 minutes. In this study, water treatment performance was investigated compared with the existing rapid sand filtration process. The membrane system was operated with no significant problems during the test period. Higher water quality was obtained in the membrane filtration than in the rapid sand filtration in terms of particulate matters such as turbidity and microbes. Although the finished water of the membrane filtration contained slightly higher concentration in dissolved matters than that of the conventional one, it met the drinking water standard. The demonstrative operation showed that membrane filtration has a reliability in drinking water treatment. Researches should be needed on cost analysis through long-term operation and optimization of operation condition for further application.

The purpose of this study was to examine the characteristics of consumer evaluative criteria based on clothing quality perception of adult males and females. A demonstrative study was conducted using a questionnaire on adults over 20 years old who were considered to afford to purchase clothes. A total of 650 questionnaires were distributed, and among them, 380 were used for the demonstrative analysis. The study used SPSSWIN V.8.0 for the analysis. Factor analysis and reliability analysis were introduced as analysis methods using the varimax rotation to classify consumer evaluative criteria for clothing purchasing. In addition, frequency analysis, correlation analysis, 1-test, multiple regression analysis, and duncan test are executed. The study result is as follows. First. expectation, importance and performance are examined by customer quality perception. Four factors- practicability, care, aesthetics, and symbolism- are classified through the factor analysis of 19 evaluative attributes based on importance. Second, differences of quality perception f3r expectation, importance and performance were found partly in customers' demographic characteristics. Third, the influential relation of satisfaction and quality perception is examined. Aesthetics and practicability have significant influence on the general satisfaction of evaluative attributes by performance.

This study aimed at drawing a scheme for more developmental and rational improvement of the screening examination system to cope with the rapidly changing industrial environment positively, enhance the food service industry qualitatively, and reinforce engaged specialty of those engaged in the industry. To set a rational improvement scheme for a cook screening system, the study conducted a prior study on job analysis of those engaged in cooking, a review on relevant laws, and a theoretical research on those problems in the current cook screening examination system. On this basis, it understood the actual condition of the current cook screening system and implemented a demonstrative analysis through a survey to draw a section on a future improvement scheme. The results were analyzed largely from two viewpoints: the general condition of the cook screening system and the future improvement scheme for the system.

This paper aims to investigate the use of reference and substitution as cohesion devices by advanced Korean EFL writers and English native writers. Twelve research articles (totaling 218 pages, 93,033 words) written in English were collected in academic journals. Half of the research articles were prepared by Koreans and the other half were written by native writers. Several demonstrative pronouns, personal pronouns and demonstrative adverbs were selected as referential cohesion devices for this study. Three substitutional cohesion devices were also chosen. Their frequency was investigated at first, after which their preference was analyzed. There was not much difference in the overall use of cohesion devices between the two groups. Some devices were used by Korean writers more often than native ones. Reasons for this could be high English proficiency of Korean writers, their hyper-correction or the influence of Korean culture. Other more distinctive cohesion features such as conjunctions are recommended for analysis of cohesion in future research.
