A lot of foreign objects(ceramics, pottery, bronze, glassware and coins, etc.) have been found in the archaeological sites in Korea. These foreign objects are the evidences of the cultural exchanges of that time, whose scale and routes are an important part of the studies in ancient history. So it is crucial to accumulate basic reference information such as the raw materials and the production method of these objects through scientific researches, along with archeological researches. These scientific research materials provide a basis for finding the importing route and the origin of these objects. Besides, we can find out extraordinary and distinctive production technique by comparison with tile domestic objects. This article reports the result of an analysis, performing on 36 samples of the glassware fragments excavated from the South Tomb of the Hwangnamdaechong, to verify their components and note peculiar features. We have analyzed the major and minor components of 10 elements, and then by using these data examined the differences in the composition of components, varying with the origin and color of glassware. We used the PCA(principal component analysis) as the statistical method to classify the sample in order to find out how the samples formed groups.

In FMEA, the risk priority number(RPN) is used for risk evaluation on each failure mode. It is obtained by multiplying three components, i.e., severity, occurrence, and detectability of the corresponding failure mode. Each of the three components are usually determined on the basis of the past experience and technical knowledge. But this approach is not strictly objective in evaluating risk of a given failure mode and thus provide somewhat less scientific measure of risk. Assuming a homogeneous Poisson process for occurrence of the failures and causes, we propose a more scientific approach to evaluation of risk in FMEA. To quantify severity of each failure mode, the mission period is taken into consideration for the system. If the system faces no failure during its mission period, there are no losses. If any failure occurs during its mission period, the losses corresponding to the failure mode incurs. A longer remaining mission period is assumed to incur a larger loss. Detectability of each failure mode is then incorporated into the model assuming an exponential probability law for detection time of each failure cause. Based on the proposed model, an illustrative example and numerical analyses are provided.

The chlorinated dioxins and furans have attracted considerable scientific and public concern because of their environmental persistence and super-toxicity through the foodchain. Recent dioxin scandals in several military bases have also contributed to a higher awareness on the side of food consumers as well as foodwaste combustion. However, there is continuing uncertainty over the relative importance of different sources of dioxins and furans to the soil environment. In difference to those awareness there is a main influence of potential soil contamination on the dioxin contents in groundwater. It is, therefore, important to provide a sound scientific framework and basis by which to evaluate the significance of the presence of dioxin in soils. Consequently, we have to identify the characteristics and nature of dioxin released into the soil environment, especially in agricultural aspect.

Probability plays a very important role in modern society as an essential tool for solving various kinds of problems from our real life or scientific province. However, most of precedent studies on probability pointed out that many students had difficulties in understanding the nature of it, and that probability teaching method in the classroom is easily led only to calculation system, which is isolated from practical applications. In this paper, I make a close study further onto these themes, by analyzing the 8th grade textbooks through these following questions; how do the textbooks deal with calculation of probability that certain two events occur at the same time? On the practical basis, how do they make use of probability as a problem-solving instrument in both actual life and scientific fields? After these, I try to extract some features and issues of probability teaching method in current Korean textbooks.

This research is aimed the furthest development of the conception of Human capital formation. The study made on the base of methods of scientific classification and systematization; dialectical method and the method of scientific abstraction, systematic and comparative analysis; expert assessment and ratings. Formation of the competitive human capital is one of the most important goals of modern development of Kazakhstan in condition of the innovative economy construction. In this context the necessity of formation and development of the effective human capital considerably increases. Realization of this requires definition of a technique of measurement of its cost as well. The authors attempt to calculate the value of human capital for Kazakhstan during independency time. In order to determine the methods of its quantitative and qualitative assessment different methodological ways for human capital research are studied. On the basis of the study, it was revealed that formation of the competitive human capital can't be considered in a separation from development and modernization of system of quality education, improvement of the employment sphere, worthy payment for work.

The Queen of the Air, John Ruskin-s highly elliptical publication of 1869, elaborates a complex mythology as a way of responding to the prevalence of scientific thinking, widespread environmental degradation, the pernicious effects of political economy, and mechanistic labor. Benjamin-s desire to rescue human experience from prevailing scientific conceptions is reminiscent of Ruskin-s fear that the peculiar power that shapes the unities of the natural world is simultaneously being "beaten down by the philosophers into a metal or evolved by them into a gas" and obscured by the dreams and theories of philosophers and theologians. As a critic remarks, in Benjamin-s-and, we would add, Ruskin-s-view, "what the modern era lacked was a basis for continuity which would prevent experience from disintegrating into a desultory and meaningless series of events." Despite its frenetic hyper-associativity, then, The Queen of the Air contains a key element that Benjamin believes is necessary for "redemption": the desire for a new form of consciousness that recognizes links to the past and thus to the longings and dreams of our forebears. Thus, although Ruskin most immediately influences Proust, who in turn influences Benjamin, Benjamin-s thought is far more Ruskinian than critics have heretofore observed. Just as Benjamin helps us make sense of the ways in which The Queen of the Air is caught in the grip of the shocking associativity of modern life, so Ruskin assists us in discerning similar impulses in Benjamin-s attraction to a form of archaic consciousness that can, by altering the modern form of perception, reenchant the present.

I criticize Mou's moral metaphysics and propose the alternative depending on Kant's analysis on the sublime. (1) Mou's moral metaphysics conflicts with the scientific world view. (2) Kant's 'aesthetic space' does not conflict with the scientific world view. Futhermore, Kant's 'aesthetic space' satisfies the conditions which Mou's moral metaphysics requires. (3) Mencius's autonomous morality is not sufficient for justifying the moral law or categorical imperative. (4) At this point, the sublime plays the important role in bridging between nature and morality. (5) In Kant's context, the possibility of the autonomous moral action is achieved on the basis of the educated feeling of the sublime.

The Chemical Substances Control Act has been legislated to counter the risks posed by chemical substances to public health and the environment, but a number of small- and large-scaled incidents related to hazardous chemicals continue to occur every year. The Korean Ministry of Environment takes legal responsibility for prevention, preparedness, and response to nationwide chemical accidents under the Chemical Substances Control Act. The determination of chemical accidents that occur during hazardous chemical handling processes is based on the Article 2 (Definitions) of the law and the administrative criteria for judgement of chemical accidents. However, there are certain ambiguities in the scientific basis for determining chemical accidents under the current regulations. Whether or not a chemical accident has a direct influence on penalties and administrative measures for a workplace where an accident occurred, it is necessary to find reasonable criteria for determining chemical accident based on legal and scientific evidence.

The purpose of this study was to investigate brain activation pattern and functional connectivity network during experimental design on the biological phenomena. Twenty six right-handed healthy science teachers volunteered to be in the present study. To investigate participants' brain activities during the tasks, 3.0T fMRI system with the block experimental-design was used to measure BOLD signals of their brain and SPM2 software package was applied to analyze the acquired initial image data from the fMRI system. According to the analyzed data, superior, middle and inferior frontal gyrus, superior and inferior parietal lobule, fusiform gyrus, lingual gyrus, and bilateral cerebellum were significantly activated during participants' carrying-out experimental design. The network model was consisting of six nodes (ROIs) and its six connections. These results suggested the notion that the activation and connections of these regions mean that experimental design process couldn't succeed just a memory retrieval process. These results enable the scientific experimental design process to be examined from the cognitive neuroscience perspective, and may be used as a basis for developing a teaching-learning program for scientific experimental design such as brain-based science education curriculum.

As Damyang has preserved both beautiful natural environment and tradition very well, it needs colors which can coexist with Damyang while preserving it as it is rather than colorful and refined colors. However, the present Damyang deteriorates the quality of beautiful natural scenes by chaotic uses of colors. Therefore, colors which can represent symbolism based on the present colors of Damyang should be used so that everyone can be pleased with them. Finally, the basic colors decided were classified into main, supplement and highlight colors in consideration of characteristics of each scene and they were effectively arranged based on the colors decided. If such colors and color schemes are properly applied according to characteristics of scenes, ecological, historical, cultural and traditional scenes of Damyang can be preserved consistently. Academic literature uses the abstract to succinctly communicate complex research. An abstract may act as a stand-alone entity instead of a full paper. As such, an abstract is used by many organizations as the basis for selecting research that is proposed for presentation in the form of a poster, platform/oral presentation or workshop presentation at an academic conference. Most literature database search engines index only abstracts rather than providing the entire text of the paper. Full texts of scientific papers must often be purchased because of copyright and/or publisher fees and therefore the abstract is a significant selling point for the reprint or electronic version of the full-text. Abstracts are protected under copyright law just as any other form of written speech is protected. However, publishers of scientific articles invariably make abstracts publicly available, even when the article itself is protected by a toll barrier. For example, articles in the biomedical literature are available publicly from medline which is accessible through design. It is a common misconception that the abstracts in medline provide sufficient information for medical practitioners, students, scholars and patients. The abstract can convey the main results and conclusions of a scientific article but the full text article must be consulted for details of the methodology.
