Let R be a commutative ring with identity. If the nilpotent radical N il(R) of R is a divided prime ideal, then R is called a ϕ-ring. Let R be a ϕ-ring and S be a multiplicative subset of R. In this paper, we introduce and study the class of nonnil-S-coherent rings, i.e., the rings in which all finitely generated nonnil ideals are S-finitely presented. Also, we define the concept of ϕ-S-coherent rings. Among other results, we investigate the S-version of Chase's result and Chase Theorem characterization of nonnil-coherent rings. We next study the possible transfer of the nonnil-S-coherent ring property in the amalgamated algebra along an ideal and the trivial ring extension.

What is the relationship between the power of mask and the popularity of 'Umakdaejang(which means a band master in Korean)' who was one of the mask-singers in King of Masksinger? And which aspects of the contemporary Korean society were projected to this fever of Umakdaejang? This study has made efforts to answer these questions. To do this, it has examined the episodes that Umakdaejang appeared in the TV program King of Masksinger, has dealt with the origin and purpose of mask, and with the cultural meaning of the mask's concealing and revealing identity in order to understand the power of mask. Findings are as follows. Umakdaejang amplified the curiosity of his identity by displaying anonymous typicality with the mask. He also showed the resistant gestures against the forms and manners of the existing TV music programs through the way of somewhat tough, uncontrolled, and mischievous behaviors. By doing so, he exposed the desire of self-revelation. As a result, by means of its anonymity and resistance, the mask functioned as an effective apparatus being able to resist against the class polarization of the capitalist ideology. This can be viewed as the origin of the fever of Umakdaejang as well as the very power of mask itself.

Termites play an important role in the degradation of dead plant materials and have acquired endogenous and symbiotic cellulose digestion capabilities. The feruloyl esterase enzyme (FAE) gene amplified from the metagenomic DNA of Coptotermes formosanus gut was cloned in the TA cloning vector and subcloned into a pET32a expression vector. The Ft3-7 gene has 84% sequence identity with Clostridium saccharolyticum and shows amino acid sequence identity with predicted xylanase/chitin deacetylase and endo-1,4-beta-xylanase. The sequence analysis reveals that probably Ft3-7 could be a new gene and that its molecular mass was 18.5 kDa. The activity of the recombinant enzyme (Ft3-7) produced in Escherichia coli (E.coli) was 21.4 U with substrate ethyl ferulate and its specific activity was 24.6 U/mg protein. The optimum pH and temperature for enzyme activity were 7.0 and $37^{\circ}C$, respectively. The substrate utilization preferences and sequence similarity of the Ft3-7 place it in the type-D sub-class of FAE.

This study presents a discussion on the biomedical laboratory science (formally clinical laboratory science or medical laboratory science) with the identity of biomedical laboratory science, as well as the academic classification system for systematic approach. The field of biomedical laboratory science is not registered in the academic research area classification system of the National Research Foundation of Korea. Since the inception of the first department of biomedical laboratory science in 1963, about 52 departments were since established. Despite the scientific identity, biomedical laboratory science have not been acknowledged professionally in most institutions. Observing the academic research area classification, the physical therapy, occupational therapy, and dental hygiene science are systematically classified and approved the identities by the authorities. This study is freshly academic area classification system of the biomedical laboratory science. The contents of this study are summarized as follows. The medical laboratory technologist's discipline is considered within the medical and science category, clinical pathology in class, and biomedical laboratory science in division. Sections of biomedical laboratory science include hematology, transfusionology, immunology, biochemistry, microbiology, parasitology, science, molecular biology, histology, cytology, cardiopulmonary physiology, and neurophysiology.

This study performed factor analysis for 21 independent variables related to the effect of illumination and suggested the effect by multiple regression analysis on the relationship between the effect of illumination and the satisfaction of use of a dependent variable to find the effect of illumination in urban parks at night and the effect of illumination on the satisfaction of use. The results of this study are as follows; 1) Of the 21 independent variables used to study the effect of illumination in urban parks at night, the impact on safety and possibility of crime was highly. The effects of illumination by factor analysis were abstracted as effects of removing anxiety, securing safety, increasing use. 2) As a result of multiple regression analysis, independent variables influencing satisfaction of use in urban park were proved as effects of removing anxiety, securing safety, increasing identity, preparing atmosphere and increasing use. Also, the effect of securing safety was the most important factor; it showed a level of importance 2 times higher than the effect of removing anxiety, and 7.7 times higher than the effect of preparing atmosphere in relative contribution of the effect of illumination to satisfaction of use. 3) Of the effects of illumination influencing satisfaction of use in urban parks, the effect of securing safety and the effect of increasing visibility were more significant than the effects of removing anxiety, preparing atmosphere and increasing use. This fact means that personal safety an the identity of persons or facilities in the space of use should be considered with priority in planning or designing illumination. Also, it implies hat, for night use in urban parks, lightness of the space is required for general safety of use at parks, and proper illuminance on the activity in the space of use should be required. The subject parks of this study are 8 urban neighborhood parks. The model on the effect of illumination and the satisfaction of use depends on characteristics and conditions of location of he park and user class, so the subject parks and persons should be varied, and the difference by sex or ages should be suggested.

The purpose of this study is to analyze the regionality of RCR Arquitectes's architectural characteristics and to figure out how these characteristics were applied to each project. The reason why they become world-class architects, who recently awarded Pritzker Architecture Prize, is because they deal with universality as their most previous inspiration which is harmonized with their own experience of hometown, Olot. They pursue "Equilibrium" is their fundamental aspect which is inspired by their experiences in Olot. The concept "Equilibrium" is classified into three main points. First, the close relationship between the landscape and architecture is priority in this concept, which is the potential of the place through architecture to form a new landscape and to pursue a balance with nature. In order to keep the relationship closer, they captured the intuitive idea through the watercolor sketch in the beginning of the project. And they also promoted the involvement of surrounding nature through horizontality, frame and void, etc. Secondly, they used cor-ten steel as the main material for most projects, and the symbiotic relationship with nature that allow people to have a different sensory experience. And the last feature is that their buildings are easily applied to different usage through users intend and behave so their buildings have transformed with various values. It is because they design buildings with strategy to harmonize between landscape and environment so they have various expansion as buildings or objects. The present era of globalization, architecture with regional identity plays an important role in conveying the values of each region. The purpose of this study is to investigate about RCR Arquitectes, who informed about the Olot and Spain's regionality, and to consider the development of architecture that implies our country's identity.

Quite arguably, W. E. B. Du Bois is the first figure in the history of black nationalism who engaged most persistently and systematically with the dominant ideology of racism and white supremacy. It is not too much to say that, by contending with the Eurocentric but taken-for-granted concept of the 'Negro' in the turn of the century, Du bois has laid the theoretical and ideological cornerstone of postcolonialism today. But his concept of race varied over time and was even contradictory in the same writings. The early Du Bois defined race as something historically made rather than biologically given and determined. Yet he didn't utterly deny the significance of physical traits and skin color in constructing racial identity. His notion of the 'Negro' was not unambiguous, either. While drawing on the 'soul' of 'black folk' to undermine the Eurocentric dichotomy of white/mind and black/body, Du Bois argued that there is some kind of 'spiritual' differences between whites and blacks, differences that are essentially inherent and hereditary in the 'Negro.' Such essentialist notion of race and the 'Negro' was on the wane in the later Du Bois, especially after his encounter with Marxism. He came to think of race merely as a discourse of racism that can be subverted and even appropriated for anti-racist practices. Following the Marxist assumption that 'the color line' is a class conflict on the international level, Du Bois contended that the 'Negro' is an outcome of slavery which is in turn a subsystem of Western capitalism. He also argued that, since the 'Negro' is not a biological essence but a sociocultural formation, the identity of the 'Negro' can and must be reconstructed according to historical change. For Du Bois, therefore, the resistance against colonialism and capitalism became a resistance against racism. This is why his Pan-African movement shifted its gear from the American program in the initial phase to a truly 'Afrocentric' and socialist one.

As a circumstantial-existance character (the human character who takes action after grasping circumstances and fears things with reason) the Japanese were more interested in the active doctrines of Wang Yang-ming than other speculative studies. All of people were inhumanely incorporated into the rigorous class system under pressure in the samurai society. In the atmosphere of the society a natural phenomenon was understood as the ksana of change, and instead of the whole, the part was mainly described with emphasis on the reality. Therefore nature came near to the man after being reduced and then was symbolized in the Interior space. Also the classification of spaces, that is to say, the settlement of borders by the social position was shown in the great interior space like a labyrinth. As a self-existance character(the human style who carves out for and does not have a regard other's feeling), however, the Korean were much influenced by the Taoist Idea as they tried to be similar to nature in nature itself. Therefore the idea of Asaniskrota was in their origin. There was a tendency for space to be extended toward the outdoor in Korea, since the Korean people who are speculative and like to be natural tried to be close to nature. Therefore the division of spaces according to class and sexuality and the settlement of borders were already shown in outside by Che-Na-Num(Divided-Mass:Koren's own style). These are closely related with that houses were built after a village settle down in Korea while built before a village settle down in Japan. Architectural space consists of the interior and the exterior. The layout and (on of architectural space has a great variety of characters by region and culture. In other words, it can be understood which has a priority between the interior and the exterior in developing the layout and the form of architectural space. Belonging to the culture area of Chinese characters with Korea, Japan has maintained its own Identity. It has an identity in the layout and form of architectural space as well. Therefore, the architecture and architectural theories of the two countries were compared and analyzed with priority given to the traditional architecture, also the backgrounds of architecture and architectural theories of two countries were examined in this study. This study shows that each country has different characters in how to introduce nature, how to expand space and how to compose windows, including the view of nature and the cult of space. As a result, the space in Korean architecture has relatively the exterior-oriented character but in Japan architecture spatial character is interior-oriented. The interior-oriented character can be relevant to the word 'reduction' and the exterior-oriented character to 'extension' after all. Also it can be thought that each character has a great relation with climate and idea of people in power.

Having gone through the international financial crisis in 1997, the Korean government has sought a new future economic breakthrough. In this line, the government chose the cultural contents business and has supported this area intensively. With the cultural contents promotion policy initiated to foster the world-class culture business based on the traditional Korean culture, Andong, which has diverse cultural traditions, was rediscovered. The Andong local government and the local power elites decided that this promotion policy can not only be an opportunity to invigorate the sluggish local economy, but also help eliminate the old-fashioned image of Andong, and thus actively promoted the cultural contents business. However, there's a conflict among the local elites over which cultural tradition should be chosen as a genuine local cultural tradition. The different views and efforts regarding the cultural identity of the region by each entity not only contributed significantly to the recovery of the local economy by revitalizing tourism, but also helped the region gain an advantageous position in competition with other regions over limited resources. This progress became the groundwork for attracting major institutions and facilities, which are essential for the revitalization of the local economy.
