This paper is to examine the meaning of activities of a number of artists who belong to Constructivism in the fashion design area during early twentieth century. After Russian Revolution, the artists like Nadeshda Lamanowa, Ljubow Popowa and Warwara Stepanova decided to devote to practical art area for many People. It's very meaningful for them to jump into real work places like a textile mill and a clothing workshop instead of staying in fine art area. Constructivism is more related to social interest rather than individual thing. The artists tried to apply their modeling principles in fine art to dress making. We can see the geometrical lines and shapes and big differences In colors and material in their dress. The artists had also shown personal tastes to dress works. This idea of togetherness with their time and even to create the style of it. was very renovative at that time and gave an influence on the later styles.

This study proposed a plan to seek a more practical way of life norm education of today's families on the basis of family rule in the traditional society by comparison between the older generation's family life rule education and college students. The study was made by analysing rules in Chosun Dynasty questionaire nair was drawn up on the basis of it. The subjects of this study were college students of one largest cities and their 800 parents. Collected data was processed by frequency analysis, ANOVA, interrelation and regression which are used through SPSS computer programs, Study results show that acceptance level is higher among the older generation but the necessity of family standare education is urgent beyond the generations. Also people who have lived with grand parents feel more necessity of education family norm. When the education could not be made in families because parents excessive protection examination-centered education, and bad effects of mass media then emphasis has to be made to create life culture which makes family norms to be kept continuously by the education at schools, education culture centers and public facilities.

We present a new way to create a thermally stable, highly strained germanium (Ge) optical resonator using a novel Ge-on-dual-insulators substrate. Instead of using a conventional way to undercut the oxide layer of a Ge-on-single-insulator substrate for inducing tensile strain in germanium, we use thin aluminum oxide as a sacrificial layer. By eliminating the air gap underneath the active germanium layer, we achieve an optically insulating, thermally conductive, and highly strained Ge resonator structure that is critical for a practical germanium laser. Using Raman spectroscopy and photoluminescence experiments, we prove that the novel geometry of our Ge resonator structure provides a significant improvement in thermal stability while maintaining good optical confinement.

With such basic conceptions in mind. this study was aimed at reviewing the unique formative aesthetics of scarves for creation of modern apparel design. To this end, the drapeability of the rhythmically wrinkled fabric of scarf as well as its tying and enclosing representation were introduced into the apparel details and silhouette to create an apparel design flattering the moderns unique sense of aesthetics and emotion. In the same vein. threads were superimposed on the planar fabric to express a sense of volume and thereby, pursue a unique decorative effect of rich texture. Specifically. the objectives of this study are to highlight the practical use of scarf warming and its decorative formative aesthetics and thereby, apply it to apparel designs and develop an art fabric using the machine embroidery technique. and ultimately, suggest the possibility of unique but highly value-added apparel designs.

Data warehouse is an intelligent store of data. A metadata is critical for implementing data warehouse. Integrating data warehouse with its metadata helps create a more adaptive information system. This paper proposes a metadata-oriented data warehouse architecture that consists of seven components: legacy, extracting, operational data store, data warehouse, data mart, application, and metadata. A taxonomy for dataflow and metaflow is proposed for better understanding of the architecture. In addition, a metadata schema is built within the framework of the seven components. Lastly, the architecture with its metadata component is applied to a real-life data warehouse project for a large medical center in order to illustrate its practical usefulness.

Although This study was designed to evaluate internet communities based on knowledge creation and learning. To do so, we created and tested our research model, by using selected 20 different knowledge communities. Using the K-Means Clustering techniques, we found different characteristics and evaluated these characteristics by the criterion. The results of discriminant analysis suggested 4 different models such as 'Search Engine,' 'Open Communities,' 'Specialty Communities,' and 'Activity Communities.' The results of this study indicated that it can cover some reasons for development process of knowledge communities and that it can also create a strategic framework for practical use of knowledge communities.

In this study, Field-Programmable Gate Arrays (FPGAs) are investigated as a practical solution to the challenge of designing an optimal platform for implementing algorithms in a wireless sensing unit for structuralhealth monitoring. Inherent advantages, such as tremendous processing power, coupled with reconfigurable and flexible architecture render FPGAs a prime candidate for the processing core in an optimal wireless sensor unit, especially when handling Digital Signal Processing (DSP) and system identification algorithms. This paper presents an effort to create a proof-of-concept unit, wherein an off-the-shelf FPGA development board, available at a price comparable to a microprocessor development board, was adopted. Data processing functions, including windowing, Fast Fourier Transform (FFT), and peak detection, were implemented in the FPGA using a Matlab Simulink-based high-level abstraction tool rather than hardware descriptive language. Simulations and laboratory tests were carried out to validate the design.

Recently, as value for practical use of big data is evaluated, companies and organizations that create benefit and profit are gradually increasing with application of big data. But specifical and theoretical study about possible risk factors as introduction of big data is not being conducted. Accordingly, the study extracts the possible risk factors as introduction of big data based on literature reviews and classifies according to big data processing, data collection, data storage, data analysis, analysis data visualization and application. Also, the risk factors have order of priority according to the degree of risk from the survey of experts. This study will make a chance that can avoid risks by bid data processing and preparation for risks in order of dangerous grades of risk.

From a practical perspective, sustainable development requires the optimization of current natural resources and the minimization of derived wastes. A major concern with respect to sustainable infrastructure development is the continued depletion of easily-available natural resources and environmental matters are more serious, the concerned about waste materials which are inevitably produced in the manufacturing of the product is getting worse. These wastes must be handled and properly disposed, and many times, although this waste may be environmentally inert, it has been discarded in landfills. But current disposal methods of these by-products create not only a loss of profit for the power industry, but also environmental concerns the breed negative public opinion. therefore, this study evaluates the ECO artificial aggregate and bricks were designed and tested for the end use of fly ash.

As teachings that use the ICT are more popular, many studies on the dynamic geometry environment(DGE) are under way. An important factor emphasized in the studies is to practical use learning activities of learners. In this study, we first define the learning history data in DGE. Second we develop a prototype of the DGE that is able to collect and analyze the learning history data automatically. The environment enables not only to grasp leaning history but also to create and manage new learning objects.
