It is necessary to reduce aviation GHG(CO2) emission to ensure aviation sustainable development. Operational improvements may not contribute significantly to carbon reduction but it can sustatially reduce emission in a short term. ICAO has developed GANP and ASBU to optimize operations and countries are making efforts to expand infrastructure and develop technology. The legal barriers to operational improvement are based on the notion of state sovereignty under the Chicago Convention which allows countries to control inefficiencies based on borders or limit or prohibit the passage of aircraft. Chicago Convention does not grant unlimited freedom of air sovereignty and if the concept of state sovereignty is interpreted according to the times it is possible to achieve smooth operational improvement.

From 1876 to 1883, British mathematician James Joseph Sylvester worked as the founding head of Mathematics Department at the Johns Hopkins University which has been known as America's first school of mathematical research. Sylvester established the American Journal of Mathematics, the first sustained mathematics research journal in the United States. It is natural that we think this is the most exciting and important period in American mathematics. But we found out that the International Congress of Mathematicians held at the World's Columbian Exposition in Chicago, August 21-26, 1893 was the real turning point in American's dedication to mathematical research. The University of Chicago was founded in 1890 by the American Baptist Education Society and John D. Rockefeller. The founding head of mathematics department Eliakim Hastings Moore was the one who produced many excellent American mathematics Ph.D's in early stage. Many of Moore's students contributed to build up real American mathematics research power in early 20 century The University also has a well-deserved reputation as the "teacher of teachers". Beginning with Sylvester, we analyze what E.H. Moore had done as a teacher and a head of the new department that produced many mathematical talents such as L.E. Dickson(1896), H. Slaught(1898), O. Veblen(1903), R.L. Moore(1905), G.D. Birkhoff(1907), T.H. Hilderbrants(1910), E.W. Chittenden(1912) who made the history of American mathematics. In this article, we study how Moore's vision, new system and new way of teaching influenced American mathematical society at early stage of the top class mathematical research. and the meaning that early University of Chicago case gave.

This narrative-based study explored the extent to which acculturation level, health condition and SES influence depressive symptoms mediated or moderated by perceived respect of Korean-American older adults in the Chicago metropolitan and its suburban area. For the purpose of the study, qualitative interviews were performed and obtained robust data from 2 focus groups, 2 in-depth interviews. This study produced results by ATLAS. ti,. Qualitative analysis revealed that acculturation could influence depressive symptoms and that depressive symptoms could also be associated with hope and communication. These findings suggested that services given by service providers need to focus on communication and respect of the older Korean-American immigrants' self-determination, for they depend on it greatly when faced with the sufferings from various depressive mood changes in adjusting to new residences.

Despite various treatments, there is a tendency of convicted sex offenders to recidivate by committing additional sex crimes. Especially when the offenders are diagnosed comorbidly with paraphilia and personality disorders, effective treatment is critical because this difficult condition can be harmful to their psychological well-being and the security of the communities in which these men live. The aim of this review is to examine the comorbidity of personality disorders and paraphilia in the male sex offender population. This study is highly meaningful as not only it is the first domestic research on the link between paraphilia and sex crimes, integrating the preceding data from both domestic and international research, but also as it synthesizes the studies of criminal psychology, social welfare and clinical psychology.

In early 21st century, universities in Korea has been asked the new roles according to the changes of educational and social environment. With Korea's NURI and Brain Korea 21 project support, some chosen research oriented universities now should produce "teacher of teachers". We look 100 years back America's mathematics and see many resemblances between the status of US mathematics at that time and the current status of Korean mathematics, and find some answer for that. E. H. Moore had produced many good research mathematicians through his laboratory teaching techniques. R. L. Moore was his third PhD students. He developed his Texas/Moore method. In this article, we analyze what R. L. Moore had done through his American School of Topology and Moore method. We consider the meaning that early University of Texas case gives us in PBL(Problem Based Learning) process.

It is necessary to find the practical considerations for applying RDA in building up the bibliographic records by importing RDA records from LC or OCLC in Korea. Especially, it is not easy to apply RDA appropriately because there are many alternatives and options in RDA. Therefore, this study is to grasp the way for applying RDA in building up the bibliographic records by reviewing LC RDA guidelines and analyzing RDA cataloging policies of libraries such as University of Chicago, North Carolina State University, and Standford University. As a result, these libraries have catalogued according to LC RDA guidelines and each library has its own guidelines, i.e., in statement of responsibilities, to transcribe all but exceptionally allow to transcribe only first, in publication statement, to use 264 field or 260 field, and in resource types, to transcribe all types of content, media and carrier or to transcribe 33X with GMD. Therefore followings would be considered for RDA application. First, some variations could be allowed for special situations of libraries in applying RDA and LC RDA guidelines. Second, the hybrid records that describe the core element of RDA to non-RDA records would be written in processing AACR2 to RDA. Third;the display of 33X field would be designed for expressing the resource types.

This paper examines the life-cycle and birth cohort effect on East Asian supranational identity. This paper also explores how national identity is related with supranational identity among Koreans. Using the 2008 CCGA-EAI survey, we analyze the determinants of supranational East Asian identity. The results suggest several interesting findings. Age and national identity have positive effects on East Asian identity. Among generational cohorts, the democratization cohort were less likely than other cohorts to have East Asian identity. These findings suggest several implications. First, in Korea, unlike other countries in the Western world, the older tend to have stronger regional identity than the younger do. Second, unlike the existing literature, this paper finds that strong national identity (pride) is complementary, rather than substitutive, to supranational regional identity. This warrants further systematic research on the microfoundation on the relationship between regional integration and nationalism in Northeast Asia.

The purpose of this study is to seek practical implementation of adult learner-targeted college. For this, it first of all pointed out expanding opportunities of adult learners to learn and limitation of current lifelong education system at higher education level as well as lifelong learning centered university project. Then it selected and examined 3 university cases abroad, such as Harvard university, the university of Chicago in US and Warwick university in UK in terms of their curriculum and operating method for adult learners. In addition to the literature and case studies, this study did interviews on 5 professors with major of lifelong education and 5 managerial experts of university to suggest practical operating approach of adult learner-targeted college, which is as following. University's philosophy should be geared to meet public responsibility, specialization and persistency of the system and proper measurement be followed such as various range of admission track, prior education courses, recognition of prior learning experience, major, teaching method, curriculum and extra adult learner tailored service including financial support. Based on the study result, practical implications were suggested.

Purpose: Discrimination experienced in the early stages of life among ethnic minority adolescents is known to affect depression and also adversely affect health throughout adulthood and old age. The purpose of this study was to identify whether discrimination experienced by ethnic minority adolescents and their mothers and depression among mothers affect depression in ethnic minority adolescents according to gender. Methods: This was a cross-sectional study using the data of 2018 National Multicultural Family Survey in Korea. The study sample comprised 2,446 ethnic minority adolescents aged 11~18 and their mothers. The data were analyzed using descriptive statistics, pearson correlation analysis, and ordinal logistic regression with SPSS/WIN 25.0 and STATA IC 16. Results: 18.4% of the adolescents (boys: 15.1%, girls: 20.5 %) felt sad or frustrated sometimes or more often for at least two weeks during the past year. Also, 8.3% of the adolescents and 29.6% of their mothers experienced discrimination during the past year. Boys were influenced more than girls by bullying at school (OR=5.17, 95% CI: 2.85~9.38), academic performance (very bad's OR=5.79, 95% CI: 1.54~21.63) and mother's depression (often's OR=2.31, 95% CI: 1.14~4.64). Girls were influenced more than boys by experience of discrimination (OR=2.72, 95% CI: 1.69~4.39). Conclusion: The findings showed that discrimination experienced by ethnic minority adolescents and their mothers in Korean society increases depression in ethnic minority adolescents and has different effects by gender. Therefore, a gender-specific and mother-inclusive intervention is recommended to prevent depression in ethnic minority adolescents.

This study attempts to understand urban evolution characteristics through suburban development cases considered as a contemporary urban issue. Methods are (1) Urban Expansion Intensity Index (UEII) for the 9 cities in the Korea (1980-2010) & 49 cities in the US, (2) Morphological Spatial Pattern Analysis(MSPA) and Entropy for the developed areas in the Chicago Metro (2019). Results are (1) a suburban development could be understood the universal characteristics, (2) the characteristics of the whole region might be appeared to be in a different direction from the characteristics of its sub-cities. Implications are (1) Suburban expansion can be understood as a functionally well served urban change phenomenon and it is important to focus on the functions of sub-level cities, (2) the urban evolutionary perspective makes a difference from the developmental growth perspective. The extensive empirical studies will be beneficial for better understating of urban evolution.
