This study had the purpose to restore imaginary environment involved to symbolic thinking system of Eastern culture discontinued by scientific and reasonable rationalism of Western. To restore imaginary environment, this study selected example places such as Seoul, Beijing, Kyoto which were ancient cities of Korea, China, Japan each and used hermeneutics and phenomenological access method to draw out the element of imaginary environment by analyzing historical and cultural view of example cities. Through comparison and re-interpretation of historical and cultural view of three countries[Korea, China, Japan] in Northeast Asia, as the result of drawing imaginary environment involved within it, it was structured that the spirit and the factor of natural environment of places involved to each cities were reflected as the factor of civilized environment, organized that each element was united, and more sanctified the spirit of place step by step. This study has the meaning as first trial which comparatively analyzed city spaces of existent place of human life by new concept called imaginary environment. It may has the meaning that verifying the universality of imaginary environment involved to historical and cultural view of three Northeast Asian countries, however, there was limitation to examine specificity up to detailed elements of each city.

Most of studies on tobacco have researched it as economic or cultural factor. These studies, certainly, have the value of their own. But from time to time these studies have brought about romantic view regarding tobacco, and have been an obstacle to approach it as a medical factor. Thus this thesis will introduce documents of tobacco as medical factor. Through it we will be able to furnish researchers with information to treat poison caused by tobacco.

In this note, we shed new light on Krull domains from the point view of Gorenstein homological algebra. By using the so-called w-operation, we show that an integral domain R is Krull if and only if for any nonzero proper w-ideal I, the Gorenstein global dimension of the w-factor ring (R/I)_w is zero. Further, we obtain that an integral domain R is Dedekind if and only if for any nonzero proper ideal I, the Gorenstein global dimension of the factor ring R/I is zero.

The range-dependent overlap factor of a lidar system can be determined experimentally if a Raman backscatter signal by molecule is measured in addition to the usually observed elastic backscatter signal, which consists of a molecular component and a particle component. The direct determination of the overlap profile is presented and applied to a lidar measurement according to variation of telescope field-of-view and distance between telescope and transmitting laser. The retrieval of extinction coefficient by Raman method can generate high errors for heights below planetary boundary layer if the overlap effect is ignored. The overlap correction method presented here has been successfully applied to experimental data obtained in Gwangju, Korea.

This study aims to compare stress concentratior factors in a loaded elastic body of the infinite plate with pressure coefficients of a fluid in the potential flow. First in view of hydrodynamics, when a single elliptic cylinder in the form of a bluff body stands in the potential flow, the pressure distribution(doefficient, C$\_$p/around the elliptic cylicder which is changed according to the position(angular displacements)is theoretically analyzed and calulated; secondly, in view of theory of elasticity, when an eliptic hole which is made on a flat plate gets tension, the stress distribution(factor) around the elliptic hole which is changed according to the position(angular displacements )is theoretically(K$\_$t/) and experimentally (K$\_$e/) measured; and finally. The results are compard and examined.

This paper presents a 3D last design system that provides the 3-dimensional last data based on the FFD(Free Form Deformation) method. The proposed system utilizes the control points for deformation factor to convert from the 3D point cloud foot data to the 3D point cloud last data. The deformation factor of the FFD is obtained from the conventional last design technique, and constructed on the FFD lattice based on the bottom view and lateral view of the measured 3D point cloud foot data. In addition, the control points of FFD lattice is decided on the anatomical points of foot. The deformed 3D last obtained from the proposed FFD is saved as a 3D dxf foot data. The experimental results demonstrate that the proposed system have the descent 3D last data based on the openGL window.

Analysis has been carried out to investigate the temperature variation and the uniformity of the temperature distribution of the glass panel by infrared radiant heating. Halogen lamps are used to heat the panel and located near the top and bottom of the rectangular chamber. The thermal energy is transfered only by radiation and the radiation exchange occurs only on the solid surfaces and is considered by using the view factor. The results show that the uniformity of the temperature distribution of the panel is improved but the time for heating increases as the wall reflectivity is large. The temperature difference reaches a maximum in the early stage of the heating process and then decreases until it reaches the uniform steady-state value.

In this Paper, we analyzed the relative importance of multiple sources and their effects on innovative activities. Through factor analysis, we found 5 sources of innovative activities; university/laboratory source, within firm source, general information source, vertical/competitive relation source, and horizontal relation source. Through regression analysis, we found that (1) 'within firm source' is the most important source on innovative activities, (2) from inputs' point of view, the more 'vertical/competitive relation source' is, the less innovative activities we, (3) from outputs' point of view, innovations are more activated when 'university/laboratory source' is abundant. but, they are less activated when 'general information source' and 'vertical/competitive relation source' is abundant, and (4) according to firm size and innovation stages(newproduct innovation, upgraded product innovation, and process innovation), the effect of sources on innovative activities is different.

In recent several studies, interactional justice as well as distributional justice and procedural justice was founded as a important factor of justice. But the other studies proposed that interactional justice was a sub-dimension of procedural justice because of a very close correlation between two factors. So there are mixed point of view of the factor structure of justice. In this study, we examined the factor structure of justice using confirmative factor analysis. We hypothesized that the facto, structure of justice would be divided into three factors; distributional justice, procedural justice and interactional justice. The results of empirical study supported these hypotheses. The results of this study suggest that interactional justice should be regarded as a important factor of justice to analyze the justice and the relationship with justice and related variables more accurately.

In view of the effect of factor Ⅶ as a risk factor for essential hypertension, we investigated the length (I/D) polymorphism at position 323 promoter region and exon 8-Msp I RFLP of the human factor Ⅶ gene in the Korean patients with essential hypertension and normal controls. There were no significant differences in the allele, genotype and haplotype frequencies of these polymorphisms between normotensive and essential hypertensive subjects. The significant linkage disequilibrium was however, detected between two polymorphic sites. The Msp I RFLP and I/D polymorphism were also significantly associated with plasma triglyceride (TG) levels. Therefore, our results suggest that the significant association between two genetic variations in the human factor Ⅶ gene and plasma TG level may reflect the potential role of human factor Ⅶ gene as one of the genetic components for cardiovascular risk.
