With the modern society approaching, a lot of new paradigms have been created which can be explained by the existing space notions while suspicions on the true essence and existence of space have been raised. Ontology regards as the beginning the cause for a 'Field' which will be faced for the research of the essence of a space where 'being-in-the-world' exists. This study has analyzed the existing method of space construction in the spatial thinking and works of Peter Zumthor who mentioning ontological viewpoint as the physiological background of his works so that the ontological spatial concept may be clarified. The following is the study results. First, in order to construct the structures of his own designing into a 'Field' for experiencing the existential meaning, Zumthor chose a reductive pattern with the entire additional elements removed. The materials leading the subjects to call attention to memory and experience and the methods dealing with it enables the realization of various spatial essences. Second, the ontological event-system is required for the formation of relationship among beings. He tried to create a spatial meaning by introducing external environment into the inside and using the materials reflecting regional features and phenomenological empiricism through the multisensory experience. Third, he applied assimilation/insert/adjustment/formative change as the way of constructing the relationship between site and structure.

Pumping action in ejector systems is generally achieved through the mixing of a high-velocity and high-energy stream with a lower-velocity and lower-energy stream within a duct. The design and performance evaluation of the ejector systems has developed as a combination of scale-model experiments, empiricism and theoretical analyses applicable only to very simplified configurations, because of the generic complexity of the flow phenomena. In order to predict the detailed performance characteristics of such systems, the flow phenomena throughout the operating regimes of the ejector system should be fully understood. This paper presents the computational results for the two-dimensional supersonic ejector system with a second throat. The numerical simulations are based on a fully implicit finite volume scheme of the compressible Reynolds-averaged Navier-Stokes equation in a domain that extends from the stagnation chamber to the diffuser exit. For a wide range of the operating pressure ratio the flow field inside the ejector system is investigated in detail. The results show that the supersonic ejector systems have an optimal throat area for the operating pressure ratio to be minimized.

Assemblage has become a popular concept in modern socio-spatial theories with relational and material turns. This article investigates the concept of assemblage focusing on Deleuze and Guattari. By comparing similar concepts such as Foucault's apparatus and Actor-Network Theory, this article demonstrates that assemblage emphasizes not only deterritorialization but also (re)territorialization, and that the exteriality of relations is a critical aspect that differentiate assemblage from other relational spatial concepts. Assemblage can highlight the value of empiricism as an analytical tool, and be open to new spatial imaginations as well as multiple existences and possiblities of alternative political projects and practices.

This study was to investigate high school students' philosophical views on science and positions of constructivists; Popper, Lakatos, Toulmin, and Kuhn. The results of this study were as follows: First, most students had the eclectic position(69%): similar percentages in sex(male 67%, female 75%), stream(liberal art 72%, science 74%), and of having experience on reading books or magazines related to the philosophy of science(ever 78%, never 64%). Second, in analysis of ANDVA of science philosphical perspectives by experience of reading books, magazines, and matters related to the philosophy of science, significant difference was revealed(p<.01). Students who had ever heard of or read about the philosophy of science were tend to have Empiricism. Third, ANDVA analysis of constructivist philosphical perspectives showed that male students were nearer to Kuhn's position than female(p<.05) and students in science stream were closer to Popper than in liberal art(p<.05). And male students in science party showed a great tendency to consent Popper's perspective(p<.01). This result seems to suggest that male students tended to think social aspects more deeply than female and held Kuhn's position.

The major objective of this study is to develop practical methods for estimating sediment yield rates of medium size watersheds of which areas range from 200 to $2,000km^2$ In the first phase of the study that were presented in the companion paper followed by this paper, a methodology for estimating sediment yield rate was introduced and a total of 13 data points including eight sampled river-sediment data and five reservoir deposit data were collected. In this study, a three-parameter empirical model and a six-parameter rating model, both of which are based on empiricism, have been developed. By limited comparisons, the models developed in this study appear to be more reliable and applicable than the existing ones. According to the sediment yield data collected and the estimations by the models, meanwhile, the lowest value for the sediment yield rate of medium size watersheds in Korea is estimated to be about $100tons/km^2/yr$, and the maximum to be about $1,000tons/km^2/yr$.

Objectives: It is well known that aging and aging-related diseases are linked to the increased level of oxidative stress caused by reactive oxygen species(ROS) and reactive nitrogen species(RNS). Nonprotein-SH decreases during aging, while substances such as ROS, nitric oxide(NO), peroxynitrite($ONOO^-$), myeloperoxidase(MPO), and dityrosine show a significant increase. This study investigated the effect of Ichungwhan on the aging process by examining its effect on the generation of the above-mentioned substances. Methods: Four comparison groups of SD rats were used. They were 6 month-old rats, 24 month-old rats, and 24 month-old rats fed with food containing 0.1% and 0.3% of Ichungwhan extract. The amount of NO, $ONOO^-$, and ROS in the rats' kidneys were examined using a fluorescence microplate reader. The reagents used for this purpose include: dihydrorhodamine 123 (DHR 123), 2',7' -dichlorodihydrofluorescein, diacetate(DCFDA), and 4,5-diaminofluorescein(DAF-2). A spectrophotometer was used to investigate the reactivity of nonprotein-SH and myeioperoxidase(MPO), using reagents such as trichloroacetic acid(TCA) and tetramethylbenzidine(TMB). The amounts of MPO protein and dityrosine were measued by western blot. Results: The observed effects of Ichungwhan on rats were as follows: increase of nonprotein-SH; effective decrease of RNS level by suppression of the generation system of $ONOO^-$ and NO; decrease of ROS level; decrease of the MPO reactivity and the subsequent reduction of amount of MPO protein; retardation of dityrosine formation. It can be hypothesized, therefore, that Ichungwhan affects both the earlier and later phases of the molecular inflammatory process, and retards the aging process. Conclusions: Empirical evidence in this study supports a role for Ichungwhan in generation mechanisms of aging process-linked substances ROS, NO, $ONOO^-$, nonprotein-SH, MPO and dityrosine. Affects contrary to the aging process observed in rats beg further empiricism to investigate potential application of Ichungwhan as a medication for age-related diseases in humans.

The writer has worked out his original philosophy both scientific and religious, which he calls "Knownism" The new thought states; the word "known" in "knownism" means "already well-informed in the providence" about the essence of the things, and the true state of the reality, hence the knownism, as the existence of God is set forth as a premise. The knownism is a philosophy unified reasonably the science and the faith into one, for the humans can perceive and realize the essence and the true state, and authorize the truth transcending the experience by the scientific method. The new thought of the knownism is a bridge-building between the natural science and the religious faith. The idea explains that the life is the process to pursue the essence of the things and the god, and the truth is immanent in the original nature of things and in God′s sphere. This thought is a philorophy of possibility to solve the paradigms-to-be such as thinking, faith experience, and supernatural power, so that it presents a vision in the human life as a profitable religious science philosophy. The knownism is much different from agnosticism, skepticism, empiricism, and agnosticism. The grace of God may be detected differently from the supernatural power. The new dark clouds overspread abruptly the summer sky are not new ones but originally derived frosm worn-out water drops. Thus those are called the old clouds. The Korean word "known"(노운) of which pronunciation is same with the English "known" means the old clouds, hence also the name, Knownism. The root of the new clouds is detectable from the preserved old clouds. The old clouds symbolized in the paper indicate the essence and the principles of the things and the fittest, or the key for the solution of the problem in the epistemology, believing that everything has its own, proper nature, the writer sums up his theory by insisting that the humans have to find out the "old clouds" or the "known" in knownism to live eternally either in this world or in other dimensions, though the human beings are transformed into the other phases of life. The writer proclaims through the ideas for the United Nations to fortify the Confederate System of World Nations in order to ensure the world peace and the future of the humans.

Science cultures in the dimension of social interaction must be correlated with science cultures or science literacy in the dimension of psychological interaction. In order to develop a mature science culture, it must be assumed 1) that a science culture in a society ran be evaluated and 2) that we have to set up the criteria for evaluating it. This paper, based on the assumptions, makes an attempt to analyze the concept of science literacy underlying the PISA (Programme for International Student Assessment) conducted by OECD. The analyses are driven by the questions such as 'which philosophical backgrounds are absorbed into the concept of PISA' science literacy?' and 'What suggestions can be found with respect to the goal of enhancing the science culture?' In conclusion, the science literacy in PISA reflects the elements proposed by logical empiricism, naturalized philosophy of science, and social constructivism, which are being incorporated by the 'collaboration research program' conducted by the newly-emerging interdisciplinary field of 'science of science.' Finally, some further suggestions are added to the analyses to pursue more positive directions to induce mature science cultures in our society.

A new research paradigm is emerging within organizational behavior, in both theory and empiricism, based on the increasing recognition of the importance of emotions to organizational life. This paper suggest that emotion intelligence play a moderate variables in relationship of emotion labor and emotional exhaustion. More specifically, it is proposed that emotional intelligence, the ability to understand and manage emotions in the employee self and others, contribute to effective emotions management in organizations. Four major aspects of emotion labor, appraisal and expression of emotion in oneself, appraisal and recognition of emotion in others, regulation of emotion in oneself and use of emotion to facilitate performance, are described. Also, the emotional intelligence are consists of four aspects, frequency of appropriate emotional display, attentiveness to required displayed rules, variety of emotions to be displayed and emotional dissonance. Then I propose how emotional intelligence contributes to of relations the emotion labor and emotional exhaustion. The purpose of this research is to investigate the impact of emotion labor to employee's emotional exhaustion to explore the moderating effects of the emotional intelligence between the emotion labor and emotional exhaustion. To complete the research the data were collected through a questionnaire from 147 employees from service company. After multi-hierarchical regression analysis, the outcomes of this study are the employee's emotional exhaustion are affected negatively by the three factors: major aspects of emotion labor, regulation of emotion in oneself, use of emotion to facilitate performance, make the moderation effect between emotion labor and emotional intelligence. These results indicate that instilling in others an appreciation of the importance of work activities: encouraging of true expression individual emotions, generating and maintaining well emotional climate and cooperation situations, and managing a meaningful environment for an organizational life.

A 3-D axisymmetric computer program is developed to predict the NO behavior in SNCR system for the stoker incinerator with the waste treatment capacity, 200ton/day. To this end a turbulent reacting flow field calculation is made using proper assumption and empiricism. The stoker bed is assumed to be a homogeneous waste-volatilized gaseous state. The initial composition or reactants are assumed based on the data of the ultimate analysis. Turbulent is resolved by k-e model and turbulent reaction is handled by eddy-breakup model harmonized with empirical chemistry data for gaseous combustion, NO and urea reaction. The liquid droplet is traced by Lagrangian method incorporated by aerodynamic drag, Coriolis and crntrifugal forces. Radiation is treated by sensible heat loss model. Calculation results are in good agreement with experimental data at the outlet of post combustion chamber in Daejon 4th industrial complex. The flue gas shows the temperature range of $900\sim1000^{\circ}C$, velocity of 5m/s and NO concentration of 140ppm at the exit while the measured temperature, flue gas velocity and NO concentration are $967^{\circ}C$, $3\sim4m/s$ and $100\sim200ppm$respectively. Using the developed computer program a parametric study has been made with the variation of heat content of waste, castable length and SNCR variables for the determination of proper injector location. In general, the calculated results are consistent and physically acceptable.
