Texture imaging, which means texture image creation by co-occurrence relation, has been known as one of the useful image analysis methodologies. For this purpose, most commercial remote sensing software provides texture analysis function named GLCM (Grey Level Co-occurrence Matrix). In this study, texture-imaging program based on GLCM algorithm is newly implemented. As well, texture imaging modules for GLDV (Grey Level Difference Vector) are contained in this program. As for GLCM/GLDV Texture imaging parameters, it composed of six types of second order texture functions such as Homogeneity, Dissimilarity, Energy, Entropy, Angular Second Moment, and Contrast. As for co-occurrence directionality in GLCM/GLDV, two direction modes such as Omni-mode and Circular mode newly implemented in this program are provided with basic eight-direction mode. Omni-mode is to compute all direction to avoid directionality complexity in the practical level, and circular direction is to compute texture parameters by circular direction surrounding a target pixel in a kernel. At the second phase of this study, some case studies with artificial image and actual satellite imagery are carried out to analyze texture images in different parameters and modes by correlation matrix analysis. It is concluded that selection of texture parameters and modes is the critical issues in an application based on texture image fusion.

We present an efficient and robust technique to estimate the velocity of moving targets from a single SAR image. In SAR images, azimuth image shift is a well blown phenomenon, which is observed in moving targets having slant-range velocity. Most methods estimated the velocity of moving targets from the distance difference between the road and moving targets or between ship and the ship wake. However, the methods could not be always applied to moving targets because it is difficult to find the road and the ship wake. We propose a method for estimating the velocity of moving targets from azimuth differentials of range-compressed image. This method is based on a phenomenon that Doppler center frequency shift of moving target causes a phase difference in azimuth differential values. The phase difference is linearly distorted by Doppler rate due to the geometry of SAR image. The linear distortion is eliminated from phase removal procedure, and then the constant phase difference is estimated. Finally, range velocity estimates for moving targets are retrieved from the constant phase difference. This technique was tested using an ENVISAT ASAR image in which several unknown ships are presented. In the case of a isolated target, the result was nearly coincident with the result from conventional method. However, in the case of a target which is located near non-target material, the difference of the result between from our algorithm and from conventional method was more than 1m/s.

This research examnied the roles, the strategies and the influence of labor unions on the pension reform. In Italia labor unions were important actors in pension reform politics during 1990s, but in 2004 labor union was excluded from the pension reform. This difference is not only related with diffusion of the leftist party but also the experience of pension benefit retrenchment of the pension reform in 1995 in which labor unions had initiatives. Labor unions choose their strategies, social dialogue or mass struggle, depending on the attitudes of government. After change of government following the failure of the pension reform in 1994 Italian government tried social dialogue. In Dini reform in 1995, laborunions had initiative in making pension reform plan. Labor unions obtained member's approval using membership vote. It had repressed opposition from militant sectors effectively. However Labor unions concentrated on the issues of transition measures and protecting vested rights in seniority pension ignoring problems of contribution evasion of small-firm workers and benefit adequacy of young workers. Even when labor unions leaded social concertation processes and pursued union democracy, labor unions' influences on the pension reform had fundamental limitations.

The aim of this study was to determine key experiences of homestay guardians of unaccompanied minor Korean adolescents studying abroad in the United States through qualitative research method of grounded theory methodology. This study identified guardianship experiences and the process of adjustment to life with homestay students through in-depth interviews with 12 subjects who are Korean guardians in the United States. The results of this study classified "started with concern" as a category that leads guardians to start providing homestay accommodation, and "other's recommendation," "need for financial support," and "unexpectedly" as subcategories. This study identified "act as a mediator to resolve differences" as a key experience of guardians, and classified subcategories are "parental role" and "calculation of gains and losses" on a personal level; and "feel sorry for own children," "limited leeway of the family," and "formation of relationship between own children and homestay students" on a family level. Developed subcategories are "thirsty for attention," "vulnerability," "task on freedom and control," and "regrettable feeling in the absence of communication" with respect to relationship with students; "grade expectations," "one-way communication," "trapped between parents' and students' demands" in regard to relationship with parents; and "advice from school" in the aspect of school. "Cultural difference," "preparedness of students and parents," "age differences between guardian's children and students," "family support," "similar personalities," "guardian's motivation," and "parent's attitude" are subcategories that affect central phenomenon of guardians.

Saseol-sijo, a form of sijo with longer verses, still affords pleasure to modern readers, even when it is read without the original performance context. In this study, I focused on Saseol-sijo that induces laughter through exaggeration and caricature while singing about eagerly waiting for a lover who has left. These texts describe concurrently the emotions that are contradictory to each other, such as nostalgia and laughter. In addition, this feature reflects human's inner emotions that are not unified but rather change dynamically. Craving creates a sense of nostalgia, and also produces a comical element in nostalgia, so that nostalgia and laughter can be co-exist without conflict. In this study, 'semiotic square' was applied as the framework for interpreting the Saseol-sijo, which demonstrates the coexistence of inconsistent meanings. As a result, a Saseol-sijo which sings about waiting for a lover can be interpreted through contraires such as prohibition and authorization, craving and concerns, exposure and concealment and concentration and dispersion. The nostalgic laughter in Saseol-sijo is generally based on the conflict between the craving self and the restrictive world. A character consumed by craving may seem ridiculous and pathetic in the view of others. However, people in general would find sympathetic humor and identify with characters who portray their weaknesses or repeat their mistakes. After all, this is the laughter of compassion and reflection which Saseol-sijo evoke.

In the 1980s, traditional analytic epistemology was abuzz with proposed solutions to the Gettier problem, responses to skepticism, newly minted objections to a variety of internalist and externalist theories of justification, and enthusiastic criticisms of foundationalism and coherentism. Debates over competing analyses of knowledge and justification raged. Since then, virtue epistemology has become a diverse and increasingly well-established field. I think that most researchers in Korea will feel the name "virtue epistemology" itself as strange or unfamiliar. It is primarily because virtue epistemology has a brief history. So, virtue epistemology did not present many opportunities for its introduction to Korean researchers. Another reason is that the name of "virtue epistemology" itself has a strangeness or unfamiliarity. Since the concept of "virtue" has mainly been used in moral or ethical contexts, virtue ethics is very familiar to most people. In contrast, the name of "virtue epistemology", combining "virtue" with "epistemology", is strange to many people. This paper primarily aims to introduce virtue epistemology in our philosophical society. What is it? How is virtue epistemology different from traditional analytic epistemology? What is the nature of virtues in virtue epistemology? What are the advantages, urgent tasks, and prospects of virtue epistemology? Focusing on these questions, I seek to understand the background to the rise of virtue epistemology, the differences and relations between virtue epistemology and traditional epistemology, and the nature of virtue and the main theories in virtue epistemology.

The purpose of this study is to understand the concept of publicness in social services. Recently, it has been argued that publicness be one of the key elements of social services even under the current social service marketization. Although publicness has been discussed in different ways in various academic areas, there is no consensus of what publicness really means, especially in social services. Therefore, reviewing discussions on publicness, this study intends to discover commonly shared aspects of publicness, and ultimately to suggest meanings of publicness in social services. This study also attempts to discuss whether different types of social service producers require different types of publicness under the context of welfare mix and social service marketization. The publicness in social services is related to various aspects: the scope of service recipients, trust toward social services, appropriate composition of services, social integration, role of government, and public accountability. Also it is suggested that the specific meaning and contents of publicness can be used in different ways for each social service producer, such as public, nonprofit, or profit sector. The study has academic and practical implications. This study provides the basis for further empirical studies on publicness academically and for implementation of publicness in the field of social services practically.

This study investigates the social discourse for Korean women's leisure culture and analyzes the conflicts between the ideologies which affected to the women's leisure issues with the social and cultural context. For this purpose, this study analyzed a sum of 652,513 words of 4,614 news articles about Korean women's leisure by applying semantic network analysis. In the 1960s, both the enthusiasm for 'modernization' and 'good wife and wise mother' ideologies were simultaneously affected to women's leisure discourse. 'The good wife and wise mother' ideology have a stronger impact on women's leisure culture in the 1970s. In the 1980s, even though the Korean women had higher education background and advanced social status compared to the former periods, both 'good wife and wise mother' ideology and 'modern career women' ideology conflicted each other. The conflicts between the two ideologies were intensified in the 1990s and the women tended to sacrifice their leisure in the course of the ideological conflicts in the 2000s. In the 2010s, women who exhausted due to the intensified conflicts between the two ideologies showed preference for passive forms of leisure.

This research aims to reconstruct the philosophical content and essence of Schopenhauer's metaphysics of music in his book, Die Welt als Wille und Vorstellung, particularly in paragraph 52, and to pay close attention to its theoretical account of music in the context of traditional musical aesthetics. The question whether Schopenhauer's theory of music is about aesthetics of feeling or about absolute music is dealt with at the end of this paper. It can be answered only within the whole system of his philosophy, because Schopenhauer's theory of music is the result of his philosophical reflections, and plays an important part in his metaphysics of the will. Schopenhauer's music theory, or rather his metaphysics of music, thus cannot be treated separately from Schopenhauer's metaphysics of the will, and is connected organically with it. As the metaphysics of the will lies in suspense between the traditional metaphysical philosophy and the non-metaphysical philosophy after Nietzsche, between the idealism and the philosophy of the body, the music aesthetics of Schopenhauer oscillates between the (romantic) aesthetics of feeling and the modern idea of absolute music.

The numbers of Korean immigrants and students in the United States are steadily increasing, but there have been very few studies of their second language literacy development (Cole, Maddox, Lim, & Notari-Syverson, 2002; Scarcellar & Chin, 1993; Shin, 1994; Skilton-Sylvester, 2001; Yu, 1994). Nor do the very few studies explore the inseparable relationship between Korean literacy and English literacy within a cultural context. This study aims to compare their views on Korean writing with those on English writing to see trace the multiliteracy development of Korean learners of English in the United States. I conducted in-depth oral interviews with Korean immigrants and students of various ages. They were asked to state everything they could remember about what they have learned to write and read in their native language and in their second language across their lifetimes, focusing particularly on the institutions they attended, materials they used, people involved in their learning, and their motivations for writing. The results reveal that the participants developed a view of writing specific to the Korean context and after they moved to the United States, they struggled to readjust the values and meanings they had had for Korean literacy to the second language context. The results of this study suggest future multiliteracy studies are needed to explore multiliteracy development in terms of the meanings and values language learners associate with their multiliteracy and help educational institutions and communities to approach second language learners' multiliteracy development as a life-long experience.
