This inquiry was conducted to develop DeNOx catalyst for LNT. In order to develop appropriate catalysts, four catalysts, which do not use PGM (Platinum Group Metal), were carefully selected : Al/Co/Mn, Al/Co/Ni/Mn, Al/Co/Mn/Ca, Al/Co/Ni mixed metal oxides during preliminary experiments. Also, XRD, EDS, SEM, BET and TPD tests were carried as well to evaluate both physicochemical properties of such four catalysts. As a result of the experiment, four catalysts were composed of spinel-shaped crystals and had more than enough pore volume and size to have oxidation-reduction reaction of NOx gases. Additionally, through TPD test, all four types of catalysts were proved to possibly have an oxidation-reduction acid site and NO oxidation activities similar to commercial catalysts. Based on the results above, if we have further change in the composition components and active ingredients according to the catalysts that were chosen in this investigation, then we are more welcomed to expect to have an enhanced DeNox catalyst for LNT.

This study attempted to investigate the plasticity of Korean paper expressed in contemporary fashion after general inquiry into Korean paper and examine the aesthetic beauty of fashion design using Korean paper. It used the literature review and empirical data analysis together. Korea-paper fashion design, the object of actual investigation, was for Korean-paper fashion from the 1990s to the present. As a result of analysis, the following findings were obtained: First, the natural, warm and soft texture seen as pureness in Korean paper enables us to elicit naturalness from liberalness. In addition, Korean paper not only has the tough characteristic of its material but also has the natural characteristic of abandoning its original nature and complying and adhering to its a given nature. Korean-paper fashion design, using this natural beauty and frank nature, bears the pure image of excluding decoration. Second, the overlapping of the surface on the surface expressed in Korean-paper fashion design forms one space with the sense of depth because of its transparency and expresses temporality through repetition. And the work of folding it with other materials and pasting them up with together demonstrates the effect of reflection because its original transparency. This effect is the specificity created in the collage technique using Korean paper and is the advantage of coming to obtain a wider freedom of expression. Korean-paper fashion design expresses transparency using this repetition and overlapping, Third, Korean paper has the simple rather than luxurious aspect. Owing to this nature, fashion design looks as if there were the greed inherent behind the work made from Korean paper though the complex technique applied to it. And it expresses the restraint of Korean paper using its original white color, the exclusion of decoration and simple design. Fourth, Korean paper is more likely to be changed by the outside influence because of formation. It has its peculiar aesthetic value and original artistry to an extent that it is regarded as one artistic work. The quality and texture of Korean paper diversely vary according to the artist's working process. Like this, Korean paper is easily fused into some object without exclusivity though it may be added to it. Korean-paper fashion design has the beauty of creation that is to create a new world because Korean paper is fused into another material due to its soft nature.

The study was conducted to identify if the first-year program of science-focused school improved students' scientific core competency and science learning motivation. The first-year program of the science-focused school consisted of basic education in scientific inquiry, investigation, advanced experiment, and basic education in small research. There were a total of 262 participants in the program, and 169 students took three survey tests. Through the analysis of a group-based trajectory modeling, students were differentiated based on similarity of score changes. This study showed that the first-year program of the science-focused school significantly improved students' scientific core competency and science learning motivation. A group-based trajectory modeling found that about 40~60% of students saw the effects of the program. The students who chose the humanity track showed effects, while some students who chose the science-focused track did not show effects. A group-based trajectory modeling showed the methodological effects of identifying the change process of individual students. This study identified the positive effects of science-focused school policy statistically and is a meaningful example for analyzing the effectiveness of science-focused school programs.

The discussion of "new risks" in the field of social policy started to gain attention in the late 1990s and it is commonly argued that new risks are provoked by deindustrialization and/or globalization being more concentrated among the young, women and low skilled individuals. This study commences its inquiry with a conceptualization of labour market risk in an attempt to critically rethink the argument of new risk. A reevaluation of the concept is followed by an empirical investigation on the different types of risks and their changes by different degree. Eight-teen countries are selected in order to provide a comparative account to understand new risk. These are comparatively analyzed using the fuzzy-set ideal type approach to discover different types of social risks and to measure degrees of changes in relation to social risk. In sum, this paper aims to answer: what is new risk? and how do the characteristic of labour market risks differ in different post-industrial countries? The findings suggest that the types of risk are diverse and the speed or the directions of shift are also diverse.
As Oedipa Mass, the heroine of Thomas Pynchon's The Crying of Lot 49, is apparently associated with Oedipus, the hero in Sophocles' tragedy, this paper aims to show some of their similarities in quest theme and plot development as well as in the use of dramatic irony. Oedipus the King opens with a priest's pleas to relieve the Theban people from a plague and the king's promise to rid its cause by avenging the murder of the former king, as told by the oracle. Lot 49 begins as a Los Angeles law firm informs Oedipa that she is named as the executrix in her former lover Inverarity's will to sort out the mogul's estate. Ironically, however, Oedipus' investigation reveals himself to be the very cause of the national disaster, the murderer for whom he searched. Likewise, Oedipa starts her inquiry dedicating herself to make sense out of what Inverarity had left behind, only to find that the legacy was America. Sophocles and Pynchon both employ dramatic irony to provide a controlling principle for plot development in their works. In Oedipus the King, Sophocles creates mounting tension as well as distance between the reader's knowledge and the protagonist's ignorance, compressing the play's action into the moment that Oedipus discovers his real identity. For dramatic irony, however, Pynchon tends to work through authorial comments and utilize allegorical meanings of the characters' names, directing his novel at illuminating Oedipa's discovery of Inverarity's legacy as well as the meaning of Tristero, an underground postal service system. Unlike Oedipus the King that proceeds on a single line of action, Lot 49 develops in esoteric, multi-layered allusions and intricately-interrelated double strains involving Oedipa's roles as executrix and quester. At the end of Sophocles' tragedy, Oedipus stabs his eyes and decides to live in exile, realizing that, blinded, he begot his children through his mother; Oedipa comes to a painful realization that she allowed her former lover to create death-orienting America without her diversity and moral system in old times. As Oedipa now discovers herself through her search for Tristero, her tragic spirit lies in her determination to confront her binary choices between two Americas: transcendence or entropy, the Tristero possibility or Inverarity's America. Ultimately, Oedipa tries to find who will be the bidder for the Tristero forged stamps designated as lot 49, awaiting the auctioneer's cry and the "crying" of a new-born America.

This study analyzed the characteristics of the learning organization according to its characteristics, the operation method and size of each public library. In addition, the service quality of public libraries was investigated so that it was also analyzed the correlation between the characteristics of the learning organization and the quality of the service. To achieve the research objectives, 83 librarians and 343 users across seven public libraries in South Korea's metropolitan areas were surveyed. The investigation covered various dimensions of learning organizations: creating continuous learning opportunities, promoting inquiry and dialogue, encouraging collaboration and team learning, creating systems to capture and share learning, empowering people toward a collective vision, connecting the organization to its environment, and providing strategic leadership for learning. Also it was investigated aspects of service quality: affect of service, information control, and library as place. As a result of the study, for the learning organization characteristics, more than 3.4 out of 5 were qualified to have foundation of learning organizations. One attempted to categorize according to its operational method and size and compare learning organization differences between public libraries, however it was not easy to see the clear differences. Therefore it was judged that there might be another unidentified factor which gives an affect on learning organization. Furthermore, it was found that there was a positive correlation between learning organization traits and service quality. This study might signify by looking into how the learning organization, which is one of the post-bureaucratic organizational traits, appears in public libraries.
