This study was conducted in order to analyze the theories behind external protective factors. In particular, it sought to understand the influence of adolescent resilience on learning motivation. Students of a public high school located in Gyeonggi Province participated in various questionnaires during the week of March 5th, 2013. Frequency analysis, one-way ANOVA (analysis of variance), correlation analysis, and multiple regression analysis were utilized to analyze the acquired data. The results revealed that when family relationships were strong and local community expectations were high, the students' 'attention to implementation processes,' one aspect of intrinsic motivation to learn, was also high. 'Suitable levels of adventurousness and risk-taking,' another aspect of intrinsic motivation to learn, was high when school expectations were also high and when relationships at the school level were weaker. The study results verified that the theory that intrinsic motivation to learn can be enhanced by strengthening external factors to protect adolescent resilience. This study is significant in that it establishes theoretical grounds to address adolescent issues, to develop programs to prevent school dropouts, and to apply the results to future legislative policies.

Recently, the beauty service industry in Korea is growing rapidly as women have increased role in society and consumers have more diversified desire for beauty. In that sense, studies on the environment of transaction is necessary to maintain the customers who use beauty service which Is one of the most prominent services in Korea. However, there is a lack of systematic investigation on that. Under those circumstances, this study tries to propose strategies by shedding light on the reasons of store loyalty based on empirical study. Furthermore, securing regular customers is deemed to be the most important thing as the competition among stores are getting fiercer in the wake of increase in the number of beauty salons. In that light, this study tries to shed light on the transaction cost clearly which affects the store loyalty, and focuses on the development of integrated research model for the transaction cost related to the environmental characteristics of beauty service industry and for the store loyalty.

The issue of data accuracy brings a different perspective to the issue of GIS modeling, calls into a question the usefulness of data models such as DEM. Accuracy can be determined by randomly checking positional and attribute accuracy within a GIS data layer. With the increasing availability of DEM and the software capable of processing them, it is worthwhile to call attention for data accuracy and error analysis as GIS application depends on the priori established spatial data. The purpose of this paper was to investigate methods for data accuracy measurement and error detection methodology with two types of DEM's: 1 to 24,000 and 1 to 250,000 DEM released by U.S. Geological Survey. Another emphasis was given to the development of methodology for processing DEM's to create Arc/Info and GRASS layers. Data accuracy analysis with DEM was applied to a 250 sq.km area and an error was detected at a scale of 1:24,000 DEM. There were two possible reasons for this error: gross errors and blunders.

This study focuses on the analyzing the factors that determined Wedding furniture design in Modern period. Final conculusions based of the above mentioned findings are as follows; First, Jangnong has been an essential Wedding furniture item since modern period and little change in the style has been found. Second, Wedding furniture items became more various in kind such as Jangnong, Moon gap, dresser, etc,. The design of these were became bigger in size and more various furniture for storing was included. Third, factors that determired Wedding furniture design were change of family, marriage and Korea's Honsu norms, economic development, industrialization, commercialism, housing and lifestyle. Factors of housing and lifestyle were mainly affected in Wedding furniture design. Fourth, criteria for Wedding furniture design were functionality, fashion, decorativeness, tradition and symbol. But the symbolic importance of Wedding furniture has been weakened as a variety of essential Honsu items. Fifth, it was concluded that a proposed theoretical model of this study was appropriate for analyzing Wedding furniture design.

The development of recent Mathematical Logic is mostly originated in Hilbert's Proof Theory. The purpose of the plan so called Hilbert's Program lies in the formalization of mathematics by formal axiomatic method, rescuing classical mathematics by means of verifying completeness and consistency of the formal system and solidifying the foundations of mathematics. In 1931, the completeness encounters crisis by the existence of undecidable proposition through the 1st Theorem of G?del, and the establishment of consistency faces a risk of invalidation by the 2nd Theorem. However, relative of partial realization of Hilbert's Program still exists as a fruitful research program. We have tried to bring into relief through Curry-Howard Correspondence the fact that Hilbert's program serves as source of power for the growth of mathematical constructivism today. That proof in natural deduction is in truth equivalent to computer program has allowed the formalization of mathematics to be seen in new light. In other words, Hilbert's program conforms best to the concept of algorithm, the central idea in computer science.

We design authentication protocols for wireless internet not using certificates but using passwords. The target protocols include WTLS and the certificate request protocol in the wireless PKI(Public Key Infrastructure). When a password based protocol is designed and implemented for authentication and key exchange, care mutt be taken of the short length and of the not-so-randomness of passwords. To frustrate the offline guessing attack that makes use of those weaknesses, our two protocols are dependent on the password based authentication protocol that has security proof. In this paper, how to design systematically the security protocols for authentication and key exchange using passwords is presented, and the methodology hopes to be useful in some other area that needs authentication using passwords.

This study explains a turning to being cultured and geography management to get closer to popularization and specialization of geography, for which based on the assumption that they are for development of knowledge. It adopts the idea of human's geographical nature to solve the dualism which geography is referred as science and art. An object geographer studies is homogeneous, temporal as well as identifical and individual. To adopt human's geographical nature causes to human's geographical investigation, and uniting positivism to humanism. It deduces from the Bible and Evolutionism that it is characteristic of mobility, adaptabilty, connectivity, ideality, and hybridity. Geographical concepts is based on the fact that it can be applied to geographical research theme. Popularization of geography has to relate to being cultural, and specialization of geography has to relate to geography management.

This study attempts to review and evaluate the sociological engagement and media practices of an eminent French sociologist Pierre Bourdieu. In the first part of the paper, I presented some characteristics of Bourdieu's view on the sociological engagement. In the second part, I also examined Bourdieu's alternative media strategies(ARSS, Liber, Raisons d'agir) which were designed to intervene effectively in the academy and public sphere of French society. For Bourdieu, the sociological engagement can be conceived and legitimized as follows: first, the talents of the ensemble of 'specific intellectuals' in Foucaldian sense should be combined to constitute a kind of 'large collective of intellectuals' Second, this 'collective of intellectuals' should make 'corporatist' efforts to improve the autonomy of the 'field of cultural production', which is the indispensable condition for the conquest of 'the universal' Bourdieu tried to realize his logic of sociological engagement through all his intellectual works, media activities and political intervention. In appreciating positively the consistency and originality of Bourdieu's theory and practice of engagement, I proposed to reconsider some limits of his 'modern' politics - enlightenment, science, collectivity - in today's 'postmodern condition'.

Recently, there have been increasing cases of collective petitions filed in the electronic petitions system. However, there is no efficient management system, raising concerns on side effects such as increased administrative workload and mass production of social conflicts. Aimed at suggesting a methodology for estimating electronic collective petitions using anomaly detection and corpus linguistics-based content analysis, this study conducted the followings: i) a theoretical review of the concept of collective petitions, ii) estimation of electronic collective petitions using anomaly detection based on nonparametric unsupervised learning, iii) a content similarity analysis on petitions using n-gram cosine angle distance, and iv) a case study on the Voice of Citizens of Changwon City, through which the utility of the proposed methodology, policy implications and future tasks were reviewed.

We investigate, in the viewpoint of mathematical stability, the validity of the time-strain separability hypothesis employed in polymer viscoelasticity on the basis of experimental results. There have been suggested two distinct stability criteria such as Hadamard related to quick response and dissipative stability conditions, and in the limit of high deformation rate we have proved that separable constitutive equations are either Hadamard or dissipative unstable. The fact that the separability is not valid in the short time region in stress relaxation experiments exactly coincides with the results of our analysis. Therefore, since the application of the separability hypothesis incurs thermodynamic inconsistency as well as mathematical instability, such application should be avoided in the formulation of constitutive equations. In addition, careful attention should be paid to the limit of its validity even in experiments. It is also proved that there is neither theoretical nor physical validity of using the damping function.
