Being confronted with the 21th century at hand, a paradigm shift has been a common topic for development in many fields. Among these, a concept of sustainable development is the most important one to resolve conflict and nurture mutualism between science/technology(SCI/TEC) and society/environment(SOC/ENV). Looking briefly over the resent stats of the chemical industry in Japan, in this paper, we will introduce a research program named simple chemistry as an example for such a challenge.

To have a complete and comprehensive understanding of the research subject and to form an integrated legal framework for it, I have sought comprehensively to cover the major written literature on the issue under consideration. I also benefitted from a wide range of research and academic studies pertaining to the same topic, although that literature did not specifically address the issue of consumer rights in electronic contracting in the Saudi e-commerce system. Rather, it addressed only the civil and criminal protection of the consumer in e-commerce.

Customer's purchase state consists of purchase inertia and variety-seeking. As the growing brand familiarity triggers the increase of brand attractiveness, customers purchase state will be of inertia. However the excessively growing brand familiarity ignites the decrease of brand attractiveness. Followingly the purchase state will be tend to plunge into the variety-seeking state. The main topic of this study is to validate the asymmetric formation of customer's purchase states between inertia and variety-seeking. In order to follow up the main topic, this article introduces a model to freely describe the velocity of value changes depending upon the purchase states. This model will help overcome the limitation of the past studies having been based on the symmetric value changes. Based on this approach marketer will be able to decide the timing of sales promotions. This research utilized local telecommunication carrier's database of smartphone application purchase/download records. This database was collected from two years (2009 and 2010) span, the time when the smartphones started commodifying in Korea whilst most of the past studies had used purchase data of maturity stage products. From this approach utilizing the introduction stage data in the product life cycle, the probability of brand choice depending upon the purchase state on the early-stage can be probed. Moreover, this study tries to expand the research methodology from the other areas of research by knowledge sharing. Here this study introduces the methodology of section-aggregated multinomial logit to simultaneously estimate the parameters that were included in the plural multinomial logit functions while the plural functions were inter-connected. This adoption of section-aggregated multinomial logit model procedures from the computerized statistics areas is expected to nourish the marketing research for more precise analysis and estimation of effects of marketing activities.

The purpose of this study is to understand the current status and trends of the research studies published by the Society for Industrial and Applied Mathematics which is a leader in the field of industrial mathematics around the world. To perform this purpose, titles and abstracts were collected from 6,255 research articles between 2016 and 2019, and the R program was used to analyze the topic modeling model with LDA techniques and a regression model. As the results of analyses, first, a variety of studies have been studied in the fields of industrial mathematics, such as algebra, discrete mathematics, geometry, topological mathematics, probability and statistics. Second, it was found that the ascending research subjects were fluid mechanics, graph theory, and stochastic differential equations, and the descending research subjects were computational theory and classical geometry. The results of the study, based on the understanding of the overall flows and changes of the intellectual structure in the fields of industrial mathematics, are expected to provide researchers in the field with implications of the future direction of research and how to build an industrial mathematics curriculum that reflects the zeitgeist in the field of education.

The focus of this study is to analyze between South Korea and China in terms of diversity in Management Information Systems research. As a result, there is herding phenomenon regarding researches in both of the countries compared to other previous studies. There also seemed to be lack of in-depth study of basic theories and connection to related field of study considering the broad topics of management information, unlike other international journals that pursue diversity in control referencing various methodologies, analysis units and many citations. Therefore, both South Korea and China should stabilize theoretical base of MIS through securing independent field of MIS along with founding the fundamentals by searching in diversified fields, methodologies and analysis units with focused topics. The upshot here is that with respect to diversity in MIS from both countries, to alleviate herding phenomenon, enforcing accuracy of data collection and reducing convenience pursuit should be implemented. Also as criteria to select a topic, different kinds of consulting concepts and taking social issues into consideration that helps tool development and analysis power should be done. Through varied methodologies, tool development and analysis power should be assisted and analysis unit should be shifted to organization unit for Korea and team or individual for China only to augment the accessibility. As a limitation for the paper is that the data used in this analysis is secondary data. In addition, although time period used in both countries were the same, object of analysis had homogeneity in Korean case while Chinese one having heterogeneity from 19 different journals. For the future studies, multicultural comparison or time series analysis and their comparison in deeper approach with regard to object of analysis and methodologies can contribute to further MIS diversity.

This study aims to grasp the key issues and the direction for digital divide research in South Korea. Based on the 488 KCI journal articles published between 2003 and 2020, the authors analyzed the changes in the number of articles per year and the subject areas of journals. Furthermore, the topic modelling and keyword network anlaysis were applied to identify the subjects of research. The main findings can be summarized as follows: first, there was a stable trend for a while after the number of articles had increased by the year of 2007, and then there has been a sharp increase since 2019. Second, digital divide research has been conducted from diverse fields including social science, multidiscipline, and engineering. Third, the six subject areas were identified which are 'digital divide among regions', 'digital divide among people with disabilities', 'technical environment of digital divide', 'divide from information use and its consequence', 'legal and institutional environments of digital divide', and 'digital divide of the elderly'. Finally, it was shown that the areas of 'divide from information use and its consequence' and 'technical environment of digital divide' have attracted attention recently.

This study was conducted with the purpose of providing suggestions for improvement through a comparison and analysis of the services of the U.S. National Library of Medicine, the world's largest medical library, and the National Center for Medical Information and Knowledge, Korea's national medical library. Core services that need to be improved are topic-specific services, community services, services by user type, educational services, technology, facility/space services, research support services, and marketing and public relations and cooperation services. Specialized libraries are also increasingly interested in topic-specific services and public services. Efficiency in access through services for each type of user is needed, and various types of educational services that do not limit the target audience are also needed. Marketing through AI, virtual reality, and technology, facility, and space services to support the disabled, research support services centered on research ethics, research grants, and programs, and collaborative services with domestic and international libraries, academic societies, institutions, and local communities in other related fields and publicity are also needed.
