This study was to establish a framework to provide the necessary caring knowledge in preparental period by analyzing the effects of an experience of being a child-care teacher in a field based on child-care knowledge from university. The data were collected from 5 in-depth interviews for 7 weeks from July to August, 2015. The results showed that mothers who used to be child-care teachers put conversation first in the child rearing process, made a room environment similar to the activity space in a kindergarten, and evaluated themselves as mothers with a burden that their children should be different from the others. This means that they perform child rearing in a positive way by re-creating their experience and knowing the child rearing process.

The possibility of the biological treatment of MBT wastewater generated from the vulcanization accelerator manufacturing process was investigated. MBT wastewater is not biodegradable because it hinders the activity of microorganisms, and approximately 10% of the total COD can be removed after a 7 day acclimation period. The optimal conditions of the MBT wastewater for the chemical pre-treatment was pH of 3.5 and the Fenton oxidation with the addition of $Fe^{3+}$ to the wastewater after agitation for 2 hours. The Fenton-treated MBT wastewater showed approximately 20% removal of COD when treated with the activated sludge process for the mixed paper wastewater and Fenton treated wastewater.

The quality of CAD models affects the efficiency of the product development process. However, it seems that CAD modeling education in colleges simply focuses on the creation of CAD models without considering the quality or the applicability of the models. In this paper, we propose educational modeling approaches to help improve the quality and applicability of CAD models. These methods teach students to create models that include a rich set of information, facilitate downstream applications, and are precisely made with the fewest operations. A survey was carried out with students to validate these approaches.

The interest in software defects is growing. Companies are working on reducing them by various ways with a software development part, customer service part and quality management part. The defect data collected from them will be analyzed according to the condition and purpose to minimize the defect, and it will contribute to improving the quality of products. This study analyzed the software defect progress for companies based on the test maturity model, and set up the defect preventing process. They were applied to the project, and the number of defects decreased from 106 to 16. This study focused on the existing defect, which is a basic requirement for software quality management, and have importance by presenting a way to improve the software product quality with minimum resources.

This study aims to research the Kisho Kurokawa's architectural concepts, that are comprised of complex theories system, for globalization of Korea. Kurokawa's architectural concepts are composed by Metabolism, Metamorphosis and Symbiosis. And intermediate zone, ambiguity, multivalence are theories that work as media in changing process levels to three main concepts and these are used as media of Metamorphosis which embody Symbiosis. Metabolism include concepts of Metamorphosis and Symbiosis. Symbiosis is comprise of concepts of Metabolism and Metamorphosis, and is a ultimate goal of these three main concepts. Metamorphosis works as a medium in changing process levels from Metabolism to Symbiosis.

In extension to our previous study, we develop metadata that specify elements' structural orders, to increase the efficiency level of XML document's retrieval process. Then, we proposed a structure-based indexing model. We expect the model to generate a more efficient retrieval process of horizontally and vertically related elements. To evaluate the model's performance level, we developed an experimental prototype and conducted an experiment on an XML corpus. On average, descendant, ancestor and sibling retrievals were approximately twelve percent faster than the ETID model. And retrievals specifying structural orders of particular element types were approximately twenty-five percent faster than the ETID model. In conclusion, metadata, such as Etype, Asso and Lsso, may make a meaningful contribution to retrieval processes that specify elements' order.

Up to now the incomplete texture have been manufactured through the 2D surface treatment like simple painting process or printing process. But in order to obtain 3D texture like natural object, micro scales' 3D surface structure on the surface of plastic part must be formed. In this study plastic smart phone case with 3D texture was produced by developing the surface duplication technology of natural object used electro-forming technology, by developing the press forming technology converted plane stamper to curved surface stamper and by developing the injection mold and molding technology which have been installed the curved surface stamper.

This study presents the preform injection molding and the blow molding of the injection stretch-blow molding process for PET bottles. The numerical analysis of the injection molding and the blow molding of a preform is considered in this paper using CAE with a view to minimize the warpage and the thickness. In order to determine the design parameters and processing conditions in injection/blow molding, it is very important to establish the numerical model with physical phenomenon. In this study, a three dimensional model has been introduced for the purpose and flow simulations of filling, post-filling and cooling process are carried out. The simulations resulted in the warpage in good agreement with the measurements. Also, from the result of numerical analysis, we appropriately predicted the warpage, deformation and thickness distribution along the product walls.

Today's small and medium-sized enterprises in technology development for future industrial growth engine. In addition evaluation of the technological competitiveness of companies and countries for R&D investment as a significant item evaluated constantly expanding, he said. However, R&D productivity to properly measure and assess the companies rarely. This paper examines the existing technology, technology assessment, the study's limitations, the small and medium-sized companies to complement the U-IT TE and PSMP Model suggested by the design environment, and technology-related companies in the technology, the ability to comprehensively assess and as a tool to leverage, technical analysis and quantitative evaluation and production from the completion of the Process Model, presented want to formalize.

In this research, we developed the Information Circulation Model(ICM) by modifying and supplementing Information Process Model(IPM) in DNS. This ICM is used to simulate some combat situations that could not be considered with the existing DNS. We showed that this improved ICM can be applied to simulation and analysis of a variety of interests compared with IPM in DNS. We expect this study could be a basic research for further development of C4ISR effectiveness analysis in our national defense community.
