This paper delves into philosophical aspects of institutional household(IH) study. The paper argues that it is also necessary to investigate theoretical, methodological, and philosophical issues, not only prescriptive, practical, and managerial ones, in order to establish a field of study as an independent area of academic discipline. In that sense the paper is expected to contribute to the establishment of "the science of IH" as well as the growth of knowledge in that field. For philosophical discussions, the paper first reviews overall sub-fields of philosophy of science such as ontology, epistemology, methodology, and the debate on human nature. Then, it focuses on philosophical issues relating to the nature of IH including (1) the substance of institutional household as scientific investigation, (2) the epistemological basis of IH study, (3) the possibility of normal methodology in studying IH, (4) the values that IH ought to pursue, and (5) the rationale and autonomy of IH study. In the conclusion section, the paper discusses why the study on philosophical aspects in IH is critical in academic community of family resource management.anagement.

This study is to consider both the eastern and western concepts of colors focusing on the five colors(Blue, Red, Yellow, White, Black) derived from the principles of Yang and the Five Elements, which are the traditional philosophy of the East and to analyze the modern fashion on the basis of the theoretical background. This study is summarized in the following. The eastern color concept has been formed by the influence of the principles of Yin and Yang and the Five Elements, which explain the generation and extinction of the universe. When it comes to the five colors, the symbolism of the east and west has much in common relatively. Concerning the rule of the five colors match, both the rules of the east and west are highly similar with each other. As mentioned above, the study shows that the five colors concepts and match rules between the east and west have much in common. There is a high possibility to connect the compatibility and incompatibility of the eastern five colors with scientific western theory of color harmony.

Corrosion and tensile properties of zircaloy-4 cladding tube having a laser welding part in elevated temperature are studied to present the criterion of quality evaluation in nuclear reactor and to found the scientific basis of SCC, with laser welding method using by coupling up cladding tube to end cap. In the result of tensile test($400^{\circ}C$), the fracture is not happened in the welding part but base metal and the result of corrosion test($400^{\circ}C$ 1500psi steam), corrosion rate of the molten zone and PMZ is a little higher than the other zone.

Letter of Credit (L/C) is currently a very popular international settlement method frequently used in international trade processes amongst countries around the globe. Compared with other international settlement methods, however, L/C has some obvious shortcomings. Firstly, it is not easy to use due to the sophisticated processes its usage involves. Secondly, it is sometimes accompanied by a few risks and some uncertainty. Thus, highly efficient methods need to be used to assess and control these risks. To begin with, FAHP and KMV methods are used to resolve the problem of incomplete information associated with L/C and then, on this basis, Bayesian game theory is used in order to make more scientific and reasonable decisions with respect to international trade.

This research is primarily intended to propose a new concept for aggregate control of impervious coverage using remote sensing and GIS. An empirical study for a case study site was conducted to demonstrate how a standard remote sensing and GIS technology can be used to assist in implementing the aggregate control for impervious coverage as intermediary between decision makers and scientists. Guidelines for a replicable methodology are presented to provide a strong theoretical basis for the standardization of factors involved in the aggregate control; the meaningful definition of land mosaic in terms of pervious areas, classification of pervious intensity, change detection for pervious areas. Detailed visual maps (e.g. estimation of impervious surface allowable) can be generated over large areas quickly and easily to increase the scientific and objective decision-making for the aggregate control. It is anticipated that this research output could be used as a valuable reference to confirm the potential of remote sensing and GIS in the aggregate control for impervious coverage.

An immune algorithm is a kind of evolutional computation strategies, which is developed in the basis of a real immune mechanism in the human body. Recently, scientific or engineering applications using this scheme are remarkably increased due to its significant ability in terms of adaptation and robustness for external disturbances. Particularly, this algorithm is efficient to search optimal parameters against complicated dynamic systems with uncertainty and perturbation. In this paper, we investigate an immune algorithm embedded Proportional Integral Derivate (called I-PID) control, in which an optimal parameter vector of the controller is determined offline by using a cell-mediated immune response of the immunized mechanism. For evaluation, we apply the proposed control to mitigation of vibrations for nonlinear structural systems, cased by external environment load such as winds and earthquakes. Comparing to traditional controls under same simulation scenarios, we demonstrate the innovation control is superior especially in robustness aspect.

The electrochemical reduction of coumarin derivatives in 0.1M TEAP acetonitrile solution was investigated by the direct current, differential pulse polarography, cyclic voltammetry and controlled potential coulometry. The electrochemical reduction of 7-acetoxy-4-bromomethyl-coumarin(ABMC) was proceeded as an irreversible three steps(-0.58, -1.63 and -2.25 volts) of electrochemical transfer before chemical reaction. The solution color turned to yellow after the carboxyl group was reduced at 2nd step(-1.63 volts vs. Ag-AgCl) and the change in color was independant to the bromo group. Upon the basis of the results on the products analysis and the interpretaton of polarograms, a possible electrochemical reaction mechanism was suggested.

This research attempts to analyze communication effect of book-trailer as the promotion tool for book from various genre. For this research, existing book-trailers were classified into five types and prospective readers were selected as respondents for this research. Letter explanation type, Interview, cinematic production, stills and straplines, and animation were major type of book-trailer. Findings are 1) communication effect are different according to the type of book-trailers; 2) cinematic production and animation are the most effective type of book-trailers; 3) for memory and confirmation(sharing), a)stills and straplines, interview type, b) cinematic production and animation are founded as similar groups creating communication effect. Result of this research proposed the direction of production and practical use of book-trailer by scientific basis for publication marketer and book-trailer producer. ANOVA was used for analysis of hypothesis; measuring communication effect according to the type of book-trailer and sexuality.
