  • For years, research on the impact of students' attitudes on learning has maintained a spot amongst the most highly discussed topics in education. Particularly, over the past decades, researchers have made great strides in better understanding attitudes toward computers. This article presents a critical review of the current state of research by re-examining how attitudes toward computers have been studied. First, the review introduces an overview of the theoretical foundations and the origins of research on attitudes toward computers. Then, the article summarizes previous literature and knowledge about computer attitudes and provides a review of major findings from research on the effects of some factors affecting the formation of computer attitudes. The discussion reveals a number of major issues and challenges, which include unclear characterization of computer attitudes, problems with measurement tools, and the lack of studies using methods other than brief questionnaires. The unsolved problems cause conflicting, inconsistent and inconclusive results and affect interpretation in the study of computer attitudes. The article also suggests the main recent and future directions of research on attitudes toward computers. Finally, it concludes by providing implications for educators.

  • The study is the analysis on Oe-am village which is designated as a folk-preservation village in 1988 and is included in the fact of the dwelling change through Spot-Survey and Case-Investigation in the last decade from now(2001), The result shows the main change on the stand-up dining room installation, the place with the boiler and bathroom installation, the additional expansion through the combination of the small twice or third space, the using change, the prototype restoration. The reason of this change is shown the following. 1. There is the dual structure that the villager repairs that because the repairing operation is biased the prototype restoration since the government construction. 2. The internal change is come from more at thatched house than at tiled house and the order of the main element's change is Kitchen (35%), main room (30%), living room (24%) and other rest room (11%). 3. The change of the dining room in the internal composition material is the strongest and the change is included in the using change, the installation of the new sub-division in the spot and the expansion of the outside if necessary. The reason of the main change is life-style's. Therefore we can know the change of the dwelling structure and we are able to make a modern-life. Also, If the restoration or repair is necessary, the change element on that must be considered.

  • A comprehensive survey of mungbean-growing areas was conducted to observe leaf spot disease caused by Alternaria alternata. Alternaria leaf spot symptoms were observed on the leaves. Diversity of 50 genotypes of mungbean was assessed against A. alternata and data on pathological traits was subjected to cluster analysis. The results showed that genotypes of mungbean were grouped into four clusters based on resistance parameters under the influence of disease. The principal component biplot demonstrated that all the disease-related parameters (% disease incidence, % disease intensity, lesion area, and % of infection) were strongly correlated with each other. Alt a 1 gene that is precisely found in Alternaria species and is responsible for virulence and pathogenicity. Alt a 1 gene was amplified using gene specific primers. The isolated pathogen produced similar symptoms when inoculated on mungbean and tobacco. The sequence analysis of the internal transcribed spacer (ITS) region, a 600 bp fragment amplified using specific primers, ITS1 and ITS2 showed 100% identity with A. alternata. Potato virus X (PVX) -based silencing vector expressing Alt a 1 gene was constructed to control this pathogen through RNA interference in tobacco. Out of 50 inoculated plants, 9 showed delayed onset of disease. Furthermore, to confirm our findings at molecular level semi-quantitative reverse transcriptase polymerase chain reaction was used. Both phenotypic and molecular investigation indicated that RNAi induced through the VIGS vector was efficacious in resisting the pathogen in the model host, Tobacco (Nicotiana tabacum). To the best of our knowledge, this study has been reported for the first time.

  • The lobby is the space that contributes the most to conveying the first impression of an enterprise or company that is occupying a building, and enhances the quality of the urban or business environment around an office building. Transparency is the biggest change in architecture since the modern age began, and it is the most important element of the lobby expression methods. Therefore this study was an attempt to understand the expression method of transparency which is expressed in the lobby space of office buildings, and used documentary survey and field survey to analyze it. In the examination of the theoretical background of transparency to make a specific study purpose, and based on an on-the-spot probe document, an attempt was made to grasp the expression method of Visual Transparency and Phenomenal Transparency. The data collected during this investigation was studied and a correlation coefficient. A summary of the findings of this study is as follows: 1) Transparent materials does not appear often in floors. But Phenomenal Transparency material is used in the floor. 2) During the survey it was discovered that Visual Transparency was often used in the walls of each investigated building. Phenomenal Transparency materials are found less in walls than in the floors of lobbies. 3) The expression methods that appeared the most in ceilings among the Visual Transparent expression methods. In the case of Phenomenal Transparency, the highest distribution is seen in ceilings. 4) The result of the analyzation of the correlation coefficient of Visual Transparency and Phenomenal Transparency is as follows: Expression method: There is more than one expression method of transparency, 'Open Sight', 'Light Material' and 'Surface Material' methods were introduced in case of the introduction of 'Transparent Material' among Visual Transparency in office building lobby space planning. If the 'Superimposed Space' method is introduced, then the 'Ambiguous Border' or 'Dual Sight' methods are introduced.

  • This survey is related to the status of education for environmental managers, who are taking charge of pollution control untilities, and its analyses. This survey is also discussing the improvements of educational course for the trainees, who have already been educated in environmental background as well as its problems. The 45% of in-service trainees were those who had graduated more than a junior college. But under the 50% of them were those who had school careers of less than a high a high school, which means that the trainees have trouble in acquiring the professional knowledges on environmental educations such as the lectures and the practice educations. All over the country, 46 junior colleges, and 65 universities which have a environmental education program, have produced the graduates who major in the environment. Therefore, it is demanded that they should be properly treated. In this research work, it is shown that the 76% of environmental managers have no certificate of environmental study. It is thought that this has resulted from the released environmental law; the untilities of the first and second grade need a manager with a certificate related with environment, the third grade utilities only need a manager with a non-specified certificate related with environment or a manager with more than 3 years environmental practice careers, the fourth and fifth grade utilities do not need the certificate related to environment. In view of relation between environment pollutions and the management of environmental utilities, it is thought that present environmental laws should be improved to be strict. The fact that the differences in regions or utilities are not considered in the contents of texts, has reduced the efficiency of education. Therefore, it is needed that the experts and the in-service managers should take part in the development of the text. In this survey, the more than 20% of trainees have negative opinions about the result of this education, which means that overall the environmental practice education should be reconsidered. In the educational methodology, more than 50% of trainees have the opinion that they want spot speciations, the audio-visual educations and the practice. Therefore, it is demaned that the subjects, syllabus, and the allotment of time ect, should be reorganized for the more practical education.
