  • XML view is proposed to integrate between XML data and heterogeneous data over distributed environment and global XML view is used to search distributed heterogeneous data. At this time, standard query language for user is XQuery and the method for processing global XQuery queries over distributed environment is one of the new research topics. One of the basic and simple methods to process distributed SQL queries is that generates local queries for processing a global query and constructs the result of the global query from the results of the local queries. However, the syntax of XQuery differs from SQL because the XQuery contains some special expressions like FOR clauses for querying to semi-structured data, of course, FOR clauses are not used in SQL. Therefore, there are some problems to adopt the method for processing global SQL queries for generating local XQuery queries. This paper defines some problems when generates local XQuery queries for processing global XQuery queries and proposes a method for generating local XQuery queries considered these problems. Also we implement and evaluate a Global XQuery Processor which uses our method.

  • Geography textbooks often have treated the world as a collection of independent nations. Also, many scholars have warned of ethnocentric bias in geography textbooks. Global education that emphasizes world interdependence and pursues global perspectives offers some possibilities to go beyond the status quo of current World Geography textbooks. The primary objective of this study is to analyze current US World Geography textbooks in terms of global education. A secondary objective is to explore a framework for rereading World Geography textbooks critically. This interpretive qualitative case study indicates that US World Geography textbooks maintain an imperialist and American-centered perspective. Especially, the case of Korea shows that other places and people are underrepresented through dichotomy, negative attitude and exclusion, misconception and stereotyping, and simplification in textbooks. Therefore, we need to detect conscious and unconscious fallacy and bias, to understand the world view and experiences of underrepresented people, and to deal with controversial global issues from diverse perspectives through global perspectives and post-colonial perspectives of global education.

  • Defense exports have overgrown in a short period, and items have been diversified with advanced high-end equipment, but exports have been stagnant due to the global economic recession and fierce competition. Weapons importers in the global market are diversified, volatility is higher, and global defense companies are also expanding their global value chain (GVC) By participating in the GVC of a global defense company, the defense SME can grow into a competitive company with specialized technology, rather than participating as a partner of a domestic system company. It is time to prepare an export promotion support plan. In this study, we selected five global companies with high value for the implementation of offset and general considerations on domestic SMEs' entry into the international parts supply chain and related cases, and investigated GVC entry requirements, the current status of cooperation partners, and the perceptions of GVC entry, through local surveys in Korea and overseas. Also, by considering the export target comprehensively, GVC stage, and the level of export competitiveness of domestic SMEs, strategies for promoting GVC participation of defense SMEs and improvements in government policies were derived and presented.

  • Objectives : We investigated the effect of Haein-tang(Hairen-tang) on short-term memory and apoptosis in dentate gyrus of the gerbils with transient global ischemia. Methods : For the induction of cerebral ischemia model in mice, common carotid arteries of gerbils were occluded with aneurysm clips for 5 min. One day after operation, Haein-tang(Hairen-tang) was administrated orally injected once a day for 15 consecutive days. Gerbils were randomly divided into four group(n=10 in each group): sham-operation group, ischemia-induction group, ischemia-induction and 50 mg/kg Haein-tang(Hairen-tang)-treated group, ischemia-induction and 100 mg/kg Haein-tang(Hairen-tang)-treated group, and ischemia-induction and 200 mg/kg Haein-tang(Hairen-tang)-treated group. The effect of Haein-tang(Hairen-tang) on memory function was investigated by using step-down avoidance task. Apoptosis was confirmed by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) staining and immunohistochemistry for caspase-3. Western blot analysis for the expressions of Bax and Bcl-2 protein was also conducted. Results : 1. Haein-tang extract significantly enhanced short-term memory in step-down avoidance task and 100 mg/kg, 200 mg/kg Haein-tang-treated group. 2. Haein-tang extract significantly suppressed TUNEL-positive cells after transient global ischemia and 50 mg/kg, 100 mg/kg, 200 mg/kg Haein-tang-treated group. 3. Haein-tang extract significantly increased caspase-3 positive cells in the hippocampal dentate gyrus after transient global ischemia and 50 mg/kg, 100 mg/kg, 200 mg/kg Haein-tang-treated group. 4. Haein-tang extract significantly decreased Bax protein expressions in the hippocampus after transient global ischemia and 100 mg/kg, 200 mg/kg, Haein-tang-treated group. Haein-tang extract significantly increased Bcl-2 protein expressions in the hippocampal dentate gyrus after transient global ischemia and 50 mg/kg, 100 mg/kg, 200 mg/kg, Haein-tang-treated group. Haein-tang extract significantly decreased Ratio of Bax protein to Bcl-2 protein in the hippocampus after transient global ischemia and 100 mg/kg, 200 mg/kg Haein-tang-treated group. Conclusions : While Haein-tang(Hairen-tang) treatment improved short-term memory by suppressing on ischemia-induction apoptosis. In the present study, Haein-tang(Hairen-tang) shows protective effect on transient global ischemia.

  • The Proxy Mobile IPv6 (PMIPv6) has been standardized by the IETF NETLMM WG for network-based mobility management. The PMIPv6 can provide IP mobility for Mobile Nodes (MNs) with low handover latency and less wireless resource usage. But, since the PMIPv6 is basically designed for local mobility management, it cannot support directly global mobility management between different PMIPv6 domains. In the PMIPv6, since all traffic is routed through a Local Mobility Anchor (LMA), it causes a long end-to-end delay and triangular routing problem. Therefore, in this paper, we propose a fast network-based global mobility management scheme and route optimization scheme with a new network entity, called Global Mobility Agent (GMA). Numerical analysis and simulation results show that the proposed scheme is able to support global mobility between different public domains with low handover latency and low end-to-end delay, compared with the PMIPv6.

  • Purpose: This study aims to examine the research output in the field of nursing at the global level during the last two decades, viz., for the period 1996-2015, with special reference to India. Some of the aspects examined include the research growth in nursing literature during the period of study, leading nursing research countries at the regional and global level, and citation analysis. Scope and Methodology: This study is global in nature, but emphasis has also been laid on India's research contribution in nursing at the global level. Aspects like regional contribution to the nursing research output have also been assessed. This study is purely based on secondary data retrieved from SCImago Journal and Country Rankings. The figures in the study are based on one particular database and are not exhaustive; hence they simply reflect a trend in nursing research at the global level. Findings: During the period 1996 through 2015, a total of 550,490 research articles were published across the world by 212 nation states at an average of 2,596 articles from each individual country. On average, during the period of study, the number of nursing research publications grew at the rate of 7.36% each year. North America has emerged as one of the leading nursing research continents of the world by publishing 218,614 research articles, constituting 39.71% of the global nursing research output. The U.S. and U.K. are the world's two leading nursing research countries, which contributed 193,819 and 61,730 research articles respectively, comprising a 35.21% and 11.21% share of global nursing research output. India and China, apart from being the two fastest growing nursing research countries, have the potential to meet the global human resource demand in the field of nursing, given the skilled and trained human resource both these countries possess in nursing. Social Implication: There is always a need to share working knowledge in some professions and nursing is one of them. There cannot be a better medium than linking practice with theory through the research medium. Metric studies in turn help to get a better idea about the amount of work done in any given field at the national and international level, thus identifying the need thereof to improve upon those areas where there is research lag.

  • It has been 15 years since Jeju Island first was designated as one of UNESCO Biosphere Reserve areas. Jeju currently holds 5 UNESCO designations and the UNFAO Globally Important Agricultural Heritage (GIAHS). The 5 UNESCO global heritages that Jeju honors are the World Natural Heritage, Biosphere Reserve, Global Geoparks Network, Chilmeoridanggut Intangible Cultural Heritage (ICH) and JejuHaenyeo ICH. The UNFAO GIAHS that Jeju honors is Jeju Batdam Agricultural Heritage System. Those global titles are highly valued and recognized for environmental preservation and those global designations have attracted more visitors to the island. It is essential to see if Jeju global level heritages are recognized as they deserve attentions from home and abroad yet no holistic analysis on those 6 global level designations as a whole has been progressed to see the perception level among residents and visitors. The study aims to see the perception level of Jeju global Heritages, impact of global recognitions and the channels of the perception level. UNESCO World Natural Heritage and Haenyeo ICH have showed the highest perception level due to designation process and the amount of promotion by the managing division of Jeju municipality. The routine survey as per the result of the study regarding the perception level of those global designations could benefit Jeju tourism direction and help to preserve the island and culture.

  • This study aims to find out whether the extra-curricular programs of English Lounge, an English-only zone operated by H University, have contributed to the improvement of participants' global competency. For this purpose, pre and post course surveys were conducted on 156 students taking classes at English Lounge in the second semester of 2020. Paired t-test was run on the responses of the pre and post-questionnaire to identify any differences in global competency of the students before and after taking the classes. The results show that the English Lounge programs have significantly contributed to the improvement of students' global competency. The programs have had a different impact on enhancing participants' global competencies and Group Speak is found to have the greatest impact on global competency improvement. In case of Virtual Exchange, students' global competency has improved the most though the results are not statistically meaningful due to not enough sample size. For the differences in effectiveness of the four types of Open Activity, significant results are not obtained due to insufficient sample numbers. This study is expected lead to the development of various types of English Lounge programs that can contribute to enhancing global competency of students.

  • The recognition for future global environment was studied targeting the university students who will be grown as general public composing our society in this study. The rate recognizing as the complex space of natural objects and artifacts is very low for non-science majored university students. Also, the rate recognizing global environment change from now to the future as negative. The environment recognition should be changed as that the university students can imagine the human live together with the nature in the image of future global environment. The environment education find out and practice the method that human can co-exist together to the direction of co-exist with the nature. Also, the rate internalizing future global environment as the space the human amends for non-science majored university students. This result is interpreted as shown the point of view that the global environment can be improved by the human activity, and it suggests the direction of environment education the university should supply. The environment education direction should be converted from the eduction of environment or the eduction from environment to the education for environment. The opportunity for global environment education should be provided to all university students without the discrimination on the major in the university education course. Sustainable global environment eduction is necessary for our son and daughter live on the earth continuously.

  • AMOREPACIFIC has rapidly grown to become a successful global brand by persistently seeking and achieving success in foreign markets. In 2011, AMOREPACIFIC was ranked as one of the global top 20 cosmetics companies. What makes AMOREPACIFIC's global success noteworthy is that AMOREPACIFIC challenged the France and the US market, where competition level is the toughest. Lolita Lempicka, AMOREPACIFIC's perfume brand, was chosen as one of the top seven most popular brands in the women's perfume market in France. In addition, Amorepacific, AMOREPACIFIC's namesake skincare brand, is currently recognized as a top prestige brand in the USA. Their success played a significant role as a bridgehead for AMOREPACIFIC in becoming a global cosmetics company. The main object of this case study is to analyze how AMOREPACIFIC became a global cosmetic company through building key brands such as Lolita Lempicka and Amorepafic, among others. Therefore, this study reviewed AMOREPACIFIC's unconventional approach in launching Lolita Lempicka in France, and Amorepacific in the US by focusing on how they foresaw the future opportunities and employed innovative marketing strategies. Specifically, we focused on Amorepacific's marketing strategy under the critical period when AMOREPACIFIC achieved great success in France with Lolita Lempicka (between 1997 and 2004) and in US with the brand, Amorepacific (2003-2008). The case of AMOREPACIFIC's success in the global markets can give valuable lessons to companies that want to extend their businesses to foreign countries and ultimately become global. One such lesson is the importance of building a successful pioneer brand in a powerful bridgehead market. While domestic competitors first entered into less competitive markets such as those in South-East Asia, AMOREPACIFIC challenged the toughest markets such as the French and US markets where the incumbent companies waged the most intensive and severe battles against Lolita Lempick and Amorepacific. Through the success in France and US market, however, AMOREPACIFIC built a powerful base for its successful global expansion. Another valuable lesson is the importance of foresight in uncovering great opportunities hidden behind the trends without losing focus on the brand's core character and values. Lolita Lempicka and Amorepacific showed excellence in foresight competition, which led them to succeed against the intense competition from Goliath companies. If Lolita Lempicka and Amorepacific had just followed the popular market trend at the time, they would have never succeeded.
