While many surveys show very positive attitudes on the part of consumers towards eco-friendly products, the market share actually reflecting green IT purchases remains low in most countries. The motivations behind green IT purchase behavior are still obscure. Several studies have addressed the question of green IT diffusion from economic and normative viewpoints in an attempt to interpret IT adoption behavior. This study comes at the question from a different angle, namely negative frame, examining threat and coping behaviors using the Ordered Protection Motivation (OPM) model and threat appraisal theory. The results show that attitudes toward fairness and positive change, which are precedents of threat appraisal, play an important role in determining threat appraisal. Perceived threats in the green IT arena include habit change and ecological change. Appraisal for coping with these threats directly affects initial adoption behaviors regarding available green IT, and then indirectly encourages the purchase of new green IT products.

Cell components play vital role within the cell when the cell under goes deformation. These components are microtubules, microfilaments and intermediate filaments. Intermediate filaments are like thread and are of different types. Like microtubules and microfilaments these components also undergo the deformation and their dynamics affected when change occurs within cell. In the present study, bending of intermediate filaments are studied keeping the nonlocal effects under consideration. It is observed that the nonlocal parameter has a great impact on the dynamics of intermediate filaments. This study is made by the application of Euler beam theory.

Let M be a von Neumann algebra and .alpha., .betha. be *-automorphisms of M satisfying the operator equation .alpha.+.alpha.$^{-1}$ =.betha.+.betha.$^{-1}$ This operator equation has been extensively studied and many important decomposition theorems have been obtained by several authors (for instance see [4], [5], [2], [1]). Originally, this operator equation arose in the paper of Van Daele on the new approach of the Tomita-Takesaki theory in the case of modular operators ([7]). In the case of one-parameter automorphism groups, this equation has produced a bounded and completely positive map which can play a role similar to the infinitesimal generator (for details see [6] and [1]). A recent and one of the most important applications of this equation has been in developing an anglogue of the Tomita-Takesaki theory for Jordan algebras by Haagerup [3]. One general result of this theory is the following.

The WeChat mini program is an application embedded in WeChat that users can use without downloading and installing. After it was officially released in 2017, many travel enterprises have launched their own mini programs on the WeChat platform. This study applies affordance theory to investigate the WeChat mini program's role in tourism activities through social network analysis using the R programming language. The authors searched the topic of "how do you perceive the travel-related WeChat mini program" and then crawled the 200 comments found; 180 comments were analyzed after data cleansing. The results show that travel-related WeChat mini programs play a very important role in Chinese social network tourism activities. This paper found that WeChat played a more active role in various tourism-related interactions with Chinese social networks. Moreover, the results show how affordance theory is applied to the use of WeChat mini programs.

As the 7th mathematics curriculum reform in Korea was implemented with its goal based on Freudenthal's perspectives on mathematization theory, the research on the effect of mathematization has been become more significant. The purpose of this thesis is not only to find whether this foreign theory would be also applied effectively into our educational practice in Korea, but also to investigate how much important role teachers should play in their teaching students, in order that students accomplish the process of mathematization more effectively. Two case studies were carried out with two groups of middle-school students using qualitative-research method with the research instrument designed by the researcher. It was found that we could get the possibility of being able to apply effectively this theory even to our educational practice since the students engaged in their mathematization using the horizontal mathematization and the vertical mathematization in geometry. Also, it was mentioned that teachers' role was so important in guiding students' processes of mathematization, although mathematization is the teaching-learning theory, stimulating students' activities. Since the Freudenthal's mathematization applied in the thesis is so meaningful in our educational practice, we need more various research about this theory that helps students develope their mathematical thinking.

This study was conducted to determine whether there is a significant relationship between board structure and board committee qualities and corporate cash holdings in Pakistan. For this objective, 168 listed enterprises on the PSX for the period 2016 to 2020 were chosen as a sample from a population of 436 non-financial firms. Multiple regression analysis was used in the study to discover a relationship between board structure and board committee features and cash holdings. The study's findings revealed that board size, executive directors, and board independence have no significant impact on the firm's cash holding because they play no important part in the firm's cash holding. Auditors, audit committee size, audit committee meetings, and the compensation committee, on the other hand, have no major impact on the firm's cash holdings because they are not relevant indicators to compare with cash holdings. While board meeting frequency and leadership structure both have a negative influence on cash holding, board meeting frequency increases firm costs, whereas leadership structure causes agency problems. Results were supported by the pecking order theory, cash flow theory, and agency theory.

The purpose of this study is to analyze the meanings of signs represented in contemporary fashion based on the Peirce's trisection theory in order to present various types of sign representation that satisfies aesthetic value and characteristics of the age of information and image. Types of signs represented in contemporary fashion can be summarized into letters, numbers, codes, pictures, logos, characters and emblems. The meanings of signs were analyzed based on the Peirce's trisection theory, resulting in representation of play, brandsymbol, eroticism and suggestion. The play was categorized into infantile and parodic. The former inspires unexpected interest and laughter from contemporary people in the age of disorder through humorous characters, cartoons and illustrations. The latter inspires laughter by parodying things and it's intention is to release the isolation of people and their relative poverty through pictures for which techniques of parody and surrealism were used. Most of the brandsymbols represented by logos, used for textile and clothing design as well as accessories are optimal signs that construct brand images. Eroticism means emotion, impulses, senses of value and sexual attraction. A desire to represent sexual attraction is an expression of eroticism and self-expression to adjust in a changing society. Suggestion tends to pursue the image of harmony with nature in a world which is pressed by material civilization. Humans represent illuminating messages through direct slogans by characters, natural objects and motives of social phenomenon in pursuit of the benefits of abundant material civilization in the structure of a highly advanced scientific civilization and industrial society.

The Nonlinear dynamic response of a sandwich plate subjected to the low velocity impact is theoretically and experimentally investigated. The Hertz law between the impactor and the plate is taken into account. Using the Extended High Order Sandwich Panel Theory (EHSAPT) and the Ritz energy method, the governing equations are derived. The skins follow the Third order shear deformation theory (TSDT) that has hitherto not reported in conventional EHSAPT. Besides, the three dimensional elasticity is used for the core. The nonlinear Von Karman relations for strains of skins and the core are adopted. Time domain solution of such equations is extracted by means of the well-known fourth-order Runge-Kutta method. The effects of core-to-skin thickness ratio, initial velocity of the impactor, the impactor mass and position of the impactor are studied in detail. It is found that these parameters play significant role in the impact force and dynamic response of the sandwich plate. Finally, some low velocity impact tests have been carried out by Drop Hammer Testing Machine. The results are compared with experimental data acquired by impact testing on sandwich plates as well as the results of finite element simulation.
