The diversity of Southeast Asia can be also represented at the tremendous number of ethnic groups residing throughout its various regions even beyond national boundaries. What does it mean by the composite of numerous peoples? It has triggered a lot of problems in a nation or overall Southeast Asia. Among them, the most serious one seems to be ethnic conflicts having damaged national integration and caused political, economical, and social instability. In that respect, Karen people have been a minority group situated in the most chronic dispute in Myanmar. Since 1947 some of the Karen equipped with armed forces have been fighting against the military government currently ruling Myanmar. As the result, the refugees over 200,000 population had moved to the mountain camps located at neighboring Thailand, attracting a lot of attention throughout international societies. According to 1931 census by British colonial government, the Karen have the greatest numbers in population as minority and include 16 subgroups including Karenni(Kayah) and Pa-O seemingly excluded from its category in contemporary point of view. It means that Karen people should not be regarded as an ethnic group, and in fact do not show a homogeneous identity under the title of Karen. Given the situation, we need to reconsider the category of Karen. What does the Karen mean in a real sense? Previous studies on the Karen had been performed mainly by anthropologists or missionaries such as Marshall(1922), Hamilton (1976), Hanson Tadaw(1959), Smeaton(1920), Keyes(1979), Hayami (1992; 2004), etc. Most of them examined the Karen as a group and ignored the possibilities of representing the divergent identities vis-à-vis their subgroups. Therefore, they have focused on the myth to convert Karen people to Christianity, although the Christian Karens are less than 20% of total population. As a result, I argue that they would fail to define the real meaning of Karen. It has been caused us to recognize the Karen as a meaningless total entity to be accepted by all means. According to their arguments, the difference among Karen's subgroups is just dealt with the trivial matters that do not affect the ethnic boundary itself, still maintaining the ethnic identity as Karen. As we shall see on this thesis, this is never the case. My thesis aims at uncovering and scrutinizing the real meaning of the category of Karen. For the purpose of it, I will consider Karen people as a linguistic group from the beginning as shown in 1931 census. I argue that the Karen have been affected or exposed by various conditions or environments throughout the harsh history having happened on the areas of current Myanmar and Thailand, leading the vicissitudes of their ethnic identities.

The studied area is composed of Precambrian gneiss complex, middle Jurassic biotite granite, late Cretaceour sediments, volcanics and pink feldspar granite. Characteristic minerals of the biotite granite is plagioclase and hornblende whereas the pink feldspar granite is pink feldspar (perthite) and quartz. Plagioclase compositions of the biotite granite and the pink feldspar granite are oligoclase to calcic andesine ($An_{18-44}$) and sodic albite ($An_{0.5-5.0}$), respectively. In the variation diagrams of the Harker and normative Q-Or-Pl diagram, the biotite granite belongs to the category from granodiorite to granite, the pink feldspar granite from nomal to late granite. The values of D.I. L.I. and alkalinity of the pink feldspar granite are higher than those of the biotite granite. While CaO is enriched in the biotite granite, $K_2O$ is enriched in the pink feldspar granite. The ratio of $K_2O/Na_2O$ which indicates the relative ratio of alkali is 1.06 in the pink feldspar granite, and 0.86 in the biotite granite. In A-M-F and N-C-K diagrams both these granites are plotted in peraluminus granite ($Al_2O_3$>$Na_2O+K_2O+CaO$) region, assigned to calc alkaline series and alkaline series respectively. Put into the form of A-C-F diagram, the biotite granite falls under I-type, and the pink feldspar granite S-type. On the base of whole rock ratios of $Fe^{+3}/Fe^{+2}+Fe^{+3}$ and $^{87}Sr/^{86}Sr$ for the granites in studied area, the biotite granite indicates ilmenite series (0.26) and S-type and/or contaminated I-type ($0.72020{\pm}0.00050$), the pink feldspar granite magnetite series (0.44) and I-type ($0.70826{\pm}0.00020$).

In this research, LCA analysis of the manufacturing process of pot bearing for fixed, movable in all directions, movable in one direction was carried out to analyze the environmental load using the LCA methodology. Especially, the water footprint that has been and issue in recent years was analyzed. As a result of LCA, it was analyzed that the contribution of the plate was more than 64.2% in all of the six impact categories in the case of fixed pot bearing base, and more than 94% in the category of resource depletion and photochemical oxidant creation. In the case of all direction pot bearing and one direction pot bearing, the contribution of PTFE was the highest in the global warming and stratospheric ozone depletion, and the contribution by the plate was higher in the other impact categories. The water footprint of each type of pot bearing was analyzed as $22.4m^3\;H_2O\;eq/kg$ for one direction pot bearing, $17.1m^3\;H_2O\;eq/kg$ for fixed pot bearing, and $14.1m^3\;H_2O\;eq/kg$ for all direction pot bearing. As a result of life cycle analysis, the contribution of water use in manufacturing was more than 65% in all three types. The results of this study can be used as basic data for decision making in construction method and material selection of bridges in the future.

A model of advection-dominated accretion flows has been highlighted in the last decade. Most of calculations are based on self-similar solutions of equations governing the accreting flows. We revisit self-similar solutions of the simplest form of advection-dominated accretion flows. We explore the parameter space thoroughly and seek another category of self-similar solutions. In this study we allow the parameter f less than zero, which denotes the fraction of energy transported through advection. We have found followings: 1. For f > 0, in real ADAF solutions the ratio of specific heats ${\gamma}$ satisfies 1 < ${\gamma}$ < 5/3 for O ${\leq}$ f ${\leq}$ 1. On the other hands, in wind solutions a rotating disk does not exist. 2. For f < 0, in real ADAF solutions with ${\epsilon}$ greater than zero ${\gamma}$ requires rather exotic range, that is, ${\gamma}$ < 1 or ${\gamma}$ > 5/3. When -5/2 < ${\epsilon}$' < 0, however, allowable ${\gamma}$ can be found in ${\gamma}$ < 5/3, in which case 4{\Omega}_0$,_ is imaginary. 3. For a negative $u_0$,+ with f > 0, solutions are only allowed with exotic ${\gamma}$, that is, 1 < ${\gamma}$ or ${\gamma}$ > (5f/2-5/3)/(5f/2-1)when O < f < 2/5, (5f/2-5/3)/(5f/2-1) < ${\gamma}$ < 1 when f > 2/5. Since ${\epsilon}$' is negative, 4{\Omega}_0$,+ is again an imaginary quantity. For a negative $u_0$,+ with f < 0, ${\gamma}$ is allowed in 1 < 7 < (5|f|/2 + 5/3)/(5|f|/2 + 1). We briefly discuss physical implications of what we have found.

There are many technical problems in the recommendation system based on very large database(VLDB). So, it is necessary to study the recommendation system' structure and the data-mining technique suitable for the large scale Internet shopping mail. Thus we design and implement the product recommendation system using k-means clustering algorithm and sequential pattern technique which can be used in large scale Internet shopping mall. This paper processes user information by batch processing, defines the various categories by hierarchical structure, and uses a sequential pattern mining technique for the search engine. For predictive modeling and experiment, we use the real data(user's interest and preference of given category) extracted from log file of the major Internet shopping mall in Korea during 30 days. And we define PRP(Predictive Recommend Precision), PRR(Predictive Recommend Recall), and PF1(Predictive Factor One-measure) for evaluation. In the result of experiments, the best recommendation time and the best learning time of our system are much as O(N) and the values of measures are very excellent.

This paper proposes a O(E) polynomial-time algorithm that has been devised to simultaneously solve edge-coloring problem and graph classification problem both of which remain NP-complete. The proposed algorithm selects an edge connecting maximum and minimum degree vertices so as to determine the number of edge coloring ${\chi}^{\prime}(G)$. Determined ${\chi}^{\prime}(G)$ is in turn either ${\Delta}(G)$ or ${\Delta}(G)+1$. Eventually, the result could be classified as class 1 if ${\chi}^{\prime}(G)={\Delta}(G)$ and as category 2 if ${\chi}^{\prime}(G)={\Delta}(G)+1$. This paper also proves Vizing's planar graph conjecture, which states that 'all simple, planar graphs with maximum degree six or seven are of class one, closing the remaining possible case', which has known to be NP-complete.

The purpose of this study is to examine by which correlation the pluralistic phenomenon in text is functioned in comparison with hair style and fashion in collection. As a result, the pluralistic image in text, which was shown in modern fashion, was indicated to be pluralistic phenomenon by gender, T.P.O, coordination, and material. The pluralistic image in text for hair style can be known to have been indicated to be the pluralistic phenomenon in text for gender and to be the pluralistic phenomenon in text according to material and cultural category. As for a method of this study, it did put limitation on the part that is shown in the fashion collection from 2001 to 2007, analyzed hair-style features centering on photos, which were extracted from style.com, the online site of specializing in fashion, and carried out a literature research side by side with the theoretical background on intertextuality. The analysis in work according to the pluralistic phenomenon in text made it possible for looking at with a new sight differently from the recognition in the past, and opened the potentiality for being able to understand lots of strange representations, which have been impossible so far. The process of imitating and reconstructing each text according to compositional principle led to possibly knowing the necessity of an artist's ability that can implement the originative world.

This paper discusses a design for Korean language parsing based on subcategorization. First, we discuss some important Korean grammar elements such as syntax category, josa, omi-conjugation, syntactic affix, dependent noun and also discuss subcategorization and expression patterns. Then, we show the basic structure of Korean language parsing process. The first stage scans the input sentence and processes article, noun phrase, numeral, josa, affix, dependent noun, adjective, omi-conjugation, adverb, auxiliary verb. The second stage deals with subcategorization patterns and expression patterns. The third stage processes the clauses and the fourth stage deals with SEA(Sentence Ending+Auxiliary).

Purpose: The results of prior studies investigating main effects between diversity and team performance are neither clear nor consistent. This study seeks to provide more evidence for a direct link between these two. The present study also attempts to close a gap in the literature by examining conflict as a moderator of the relationship between diversity and team performance. Methods: As suggested by Williams and O'Reilly(1998), this study examines the effects of perception levels of three specific types of diversity (social category diversity, value diversity, and informational diversity) and two contextual moderators (task conflict and relationship conflict) on team performance. Results: The results show that perception levels of all three types of diversity are significantly related to team performance in the current sample of 313. Results also indicate that relationship conflict significantly interacted with the perception levels of diversity in relating to team performance. Results for task conflict, however, fails to support the hypothesis. Conclusion: The results suggest that the effects of diversity on team functioning depend on how diversity is perceived by team members, rather than actual diversity seen by team members. Theoretical and practical implications are reviewed, and limitations of the study and suggestions for future research are addressed.
