The recent craze for so-called skinny jeans is illustrative of the restraint of the body through dress. This phenomenon is noteworthy when considering the internalization of the corset in contemporary fashion. Grown out of the garments of soundly practical use, blue jeans have led the stream of fashion for about 150 years and now they serve as the new corset idealizing the female body in the form of skinny jeans. This study intends to examine the idealization of the body in contemporary fashion and focus on skinny jeans as an externalized corset. The struggle with corsets continues in that the real body is overwhelmed by fashion items. In the aspect of idealizing the body by constraining the body parts, skinny jeans externalize the control of the body as contemporary corsets. This study conducts literature research and content analysis as the method of investigation and focuses on women's fashion from the 20th century. Exerting a harmful influence on health (as corsets have done) the body in skinny jeans is regarded as a modifiable entity. The thinness of the body achieved by skinny jeans suggests the controlling power over the body. Moreover, this gives access to the power presented by the contemporary ideal of thinness. Skinny jeans are modern day glass slippers.

For the development of the practical methods of structrual analysis of typical VLFS. Orthortropic plate theory and a grillage beam theory and modeling techniques are studied and relevant numerical analysis are carried out. For the design of pontoon type VLFS, an efficient and reliable structural analysis techniques must be established, and as corresponding methods, two approaches mentioned above were studied in view point of their applicability and efficience. For that purpose, structural idealization is performed to make overall structural analysis first, and the structural behaviors of the model in the airplane landing simulation are evaluated. Through this study it is found that the structural idealization using orthotropic plate and grillage modeling are porved to be adequate and the numerical analysis results for real VLFS yields acceptable deformations in the corresponding simulations.

This study investigated the high school students' and science teachers' understanding of idealization involved in the physics experiment. Major research questions are as follows: (1) what kind of ideal conditions do subjects identify from the presented experimental context? (2) do subjects think how well ideal conditions are satisfied with the experiment? (3) how well do subjects expect the effect of idealization on the experimental result? (3) what kind of view point do science teachers have about the ideal condition involved in the experiment? A total of 85 subjects were given 6 questions related with the research questions I. 2. and 3. with simple experiment about the brightness of the bulbs connected with parallel to the battery. And another 4 questions for the forth research question were given to 42 science teachers. Subjects' responses were summarized and used to draw the implications for the teaching of physics experiment.

The ACI 318 stress block parameters have been closely examined for validity of their values in evaluation of flexural strength and deformability. For this the conventional definition of stress block has been used. The comparison of parameter values between ACI stress blocks and the exact approach implies that an alternative idealization other than the rectangular stress block may be required.

In this paper, we introduce and investigate a new class of modules that is closely related to the class of Noetherian modules. Let R be a commutative ring and M be an R-module. We say that M is an r-Noetherian module if every r-submodule of M is finitely generated. Also, we call the ring R to be an r-Noetherian ring if R is an r-Noetherian R-module, or equivalently, every r-ideal of R is finitely generated. We show that many properties of Noetherian modules are also true for r-Noetherian modules. Moreover, we extend the concept of weakly Noetherian rings to the category of modules and we characterize Noetherian modules in terms of r-Noetherian and weakly Noetherian modules. Finally, we use the idealization construction to give non-trivial examples of r-Noetherian rings that are not Noetherian.

This study is to setup a mathematics PBL model that is right for elementary students. PBL models are developed and applied to actual courses and analyzed. So, a specific plan and practical understanding of PBL mathematics textbooks will be presented. But in order for this to happen, first the mathematics PBL model, that can realize 7th revised curriculum's goal, needs to setup and divided into knowledge, skill and attitude domains. Through this study, the general PBL model and the PBL model appropriate for elementary mathematics was amended and supplemented, this was then applied to courses and analyzed, and the below conclusions were realized. First, mathematical idealization stage is needed for mathematical PBL model. Since an elementary student is shortcoming in problem understanding and mathematical activity, a middle step that allows the student to understand the problem situation mathematizing and find a solution mathematically is desperately needed. Therefore, in this study, we named it the mathematical idealization stage and had it setup. Second, a mathematics information collection stage needs to be prepared for a successful PBL. Through this stage, the students will have an opportunity to gather the necessary information needed and restructure it to solve the problem. Third, the organization stage in mathematical PBL model needs to be strengthened. PBL is not just completed, through the best use of mathematics subject matter to solve the problem. Organization time is needed to allow the students to grow to a more deepened and advanced level. In conclusion, there is significance in providing a specific plan for mathematical PBL model, which can be seen through this study on applying and analyzing elementary mathematics and appropriate PBL models.
