  • The study provides a quantitative and qualitative description of global research in the domain of quantum machine learning (QML) as a way to understand the status of global research in the subject at the global, national, institutional, and individual author level. The data for the study was sourced from the Scopus database for the period 1999-2020. The study analyzed global research output (1374 publications) and global citations (22434 citations) to measure research productivity and performance on metrics. In addition, the study carried out bibliometric mapping of the literature to visually represent network relationship between key countries, institutions, authors, and significant keyword in QML research. The study finds that the USA and China lead the world ranking in QML research, accounting for 32.46% and 22.56% share respectively in the global output. The top 25 global organizations and authors lead with 35.52% and 16.59% global share respectively. The study also tracks key research areas, key global players, most significant keywords, and most productive source journals. The study observes that QML research is gradually emerging as an interdisciplinary area of research in computer science, but the body of its literature that has appeared so far is very small and insignificant even though 22 years have passed since the appearance of its first publication. Certainly, QML as a research subject at present is at a nascent stage of its development.

  • Purpose: This study aimed to understand the current status of global health curricula and characteristics in nursing schools, focusing on the changes since 2015. Methods: Data were collected from the websites of 202 nursing schools nationwide in Korea. Global health curricula were analyzed using a structured framework developed by the authors. Results: Among 202 nursing schools, 173 (85.6%) schools offer global health-related courses. Of these, 72 (35.6%) schools offer a 'Multiculturalism' course, and 42 (20.8%) schools offer a 'Global Nursing' course. Fifty-nine schools (29.2%) offer both courses. Compared to the study findings in 2015, the number of global health-related courses and the percentage of global health-related courses designated as a requirement dramatically increased. An additional analysis of five syllabi of global-health related courses found several differences in the courses' aims, contents and evaluation methods. Conclusions: Due to social and political changes, nursing schools are more likely to offer global health curricula. However, there is still a lack of consensus on the core contents and approaches of such curricula, necessitating systematic discussions about the core contents and effective learning methods to increase nursing student competency in global health nursing.

  • The purpose of this research is to investigate the relationship between global citizenship, self leadership and global health competencies in nursing students and utilize the basic data for development of educational program to increase of global health competence. A convenience sample of 207 subjects were invited from three university. Data were analyzed using t-test, ANOVA and Pearson's Correlation with SPSS PC 18.0 program. Global health competencies showed that there were differences according to religion, taking education related to global health competency, exposure to mass media about global health. There were a significant positive correlation of global citizenship(r=.364, p<.01), self leadership(r=.372, p<.01) and the global citizenship of nursing students showed a significantly positive correlation of self leadership(r=.463, p<.01). Therefore, on the result of this study, when we develop the educational programs to increase the global health competencies for nursing students, we have to include global citizenship and self leadership.

  • Purpose : To evaluate the effect of global scaling analysis on brain activation for sensory and motor functional MR imaging study. Materials and methods : Four normal subjects without abnormal neurological history were included. Arm extension-flexion movement was used for motor function and 1KHz pure tone stimulation was used for auditory function. Functional magnetic resonance imaging was performed at 3T MRI (GE, Milwaukee, USA) using BOLD-EPI technique and SPM2 was employed for data analysis. On data analysis, the brain activation images were obtained with and without global scaling by fixing other parameters such as motion correction and realignment. Results : The difference in brain activation between no scaling and global scaling was not large in case of right upper extremity movement (p<0.000001). For auditory test, brain activation with global scaling showed larger activation than that of without global scaling (p<0.05). Conclusion : A caution must be taken into account when analyzing functional imaging data with global scaling especially for functional study of small local BOLD signal change.

  • To meet the requirements in the global age, the necessity and importance of global education in the field of education is rapidly increasing. However, according to the viewpoint on global education, a general consensus of its definition and model is not clear yet and the substantial outcome falls short of our expectation due to high cost, low effectiveness, and lack of persistency in the process of global education. Furthermore, there has been little research on global education for fostering global capabilities of pre-teachers. In this research, we compared and analyzed the ongoing global education programs for training global teachers in domestic universities. Also, through a study on IT fusion education system for tackling the difficulties in global education, we examined appropriate IT fusion education methods. In particular, beased on big data analysis techniques, we presented a recommendation system to complete a global curriculum, which can help a dual-degree or exchange student program.

  • In the multidatabase systems(MDBS), local autonomy and global consistency are important issues. Global consistency could be maintained by a global concurrency control algorithm and a global recovery algorithm. In this thesis, we propose a global concurrency control algorithm to ensure local autonomy and to guarantee global serializability, and a global recovery algorithm which is possible to recover the multudatabase from any failures. The proposed global concurrency control algorithm uses bottom-up approach, based on three-level transaction processing model. It can produce a local history that the execution order of subtransactions is identical to their serialization order by using dummy-operations in the server when an indirect conflict is caused between subtransactions due to local transactions. At the global module, it can efficiently validate global serializability of global transactions by checking global serializability only for the global transactions which conflict with each other.

  • This study was conducted to investigate how consumer global-mindedness affects global fashion out-of-home (OOH) advertising which global consumer culture positioning applies, and to examine the relations among global fashion brand OOH advertising, perceived fashion brand globalness, perceived quality and brand reputation. Data were collected from 238 general people in 20~30s in seoul and were analyzed by using statistic methods such as frequency analysis, reliability analysis, confirmatory factor analysis and structural d modelling by running both SPSS 18.0 and AMOS 7.0 program. The results of this study were as follows. First of all, it indicated that the fit indexes were satisfied and the overall model of this study showed a favorable goodness of it from the results of confirmatory analysis. Secondly, consumer global-mindedness had a positive impact on preference towards global fashion OOH advertising. Finally, preference towards global fashion brand OOH advertising positively affected perceived fashion brand globalness, perceived quality and fashion brand reputation. The results implies that it is necessary that fashion brands fully understand consumers' tendency and the benefits of marketing can be maximized through global positioning OOH advertising on subways which makes consumers recognize fashion brands as global ones.

  • We analyzed the structures and properties of the global financial market networks using social network analysis approach. The Minimum Spanning Tree (MST) lengths and networks of the global financial markets based on the correlation coefficients have been analyzed. Firstly, similar to the previous studies on the global stock indices using MST length, the diversification effects in the global multi-asset portfolio can disappear during the crisis as the correlations among the asset class and within the asset class increase due to the system risks. Second, through the network visualization, we found the clustering of the asset class in the global financial markets network, which confirms the possible diversification effect in the global multi-asset portfolio. Meanwhile, we found the changes in the structure of the network during the crisis. For the last one, in terms of the degree centrality, the stock indices were the most influential to other assets in the global financial markets network, while in terms of the betweenness centrality, Gold, Silver and AUD. In the practical perspective, we propose the methods such as MST length and network visualization to monitor the change of the correlation risk for the risk management of the multi-asset portfolio.

  • Purpose - This study examined the effects of susceptibility to global consumer culture (SGCC) on the brand attitude of consumers of the global SPA brand in South Korea. Research Design, Data, and Methodology -Questionnaires were used, and the sample that was extracted by the convenience sampling method comprised 703 males and females, aged 20-36. The data were analyzed with SPSS 16.0 and Amos 5.0 for frequency analysis, exploratory factor analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and structural equation modeling analysis. Results - First, conformity to consumption trends was found to have a significant effect on all four variables of SPA brand attitude (brand favorability, uniqueness, ethicality, and economic utility). Second, quality perception was found to have a significant effect on brand favorability, uniqueness, ethicality, and economic utility. Third, social prestige was found to have a positive effect on uniqueness. Conclusions - The results show that consumers' susceptibility to global culture is a significant factor in their attitude to the global SPA brand. Therefore, it would be more effective if the global SPA brand develops recognition among consumers that its products play a role in sharing new trends and global lifestyles.

  • Using GIS and socio-economical data the relationship between human activities and global environmental change Is Analysed from the view point of food productivity and CO2 emission. Under the assumption that the population problem, the food problem and global warming due to energy consumption can be stabilized through managing land use, impacts of human activities such as consumption of food, energy and timber on global environment changes, and global population capacity are Analysed using developed system dynamics model in the research. In the model the world is divided into two groups: OECD countries and the others. Used global land use data set Is land cover map derived from satellite data, and potential distribution of arable land is estimated by the method of Clamor and Solomon which takes into consideration spatial distribution of climate data such as precipitation and evapotranspiration. In addition, impacts of CO2 emission from human activities on food production through global warming are included in the model as a feedback. The results of the analysis for BaU scenario and Toronto Conference scenario are similar to the results of existing models. From the result of this study, the human habitability in 2020 is 8 billion people, and CO2 emission in 2020 based on BaU Scenario and on Toronto Scenario is 1.7 and 1.2 times more than the 1986's respectively. Improving spatial resolution of the model by using global data to distribute the environmental variables and sauce-economical indices is left for further studies.
