  • Sustainable Information Technology (IT) and Sustainable Information Systems (IS) were synonymous with Green IT-IS until recently the studies focused on sustainable IT-IS encompassing the interaction between economy, society, and environment. Here, is an attempt to understand the development in the emerging field of Sustainable IT-IS from Green IT-Green IS. The studies in the area of Sustainable IT-IS spare address diverse topics. This study attempts to provide a framework for the field of research and indicate potential research directions in the sustainable IT-IS domain. A detailed comparative analysis approach of 296 papers has been used to understand the progress of management research in Sustainable IT-IS vis-à-vis Green IT-IS. The review analyses the collated literature to understand the trends across the study period, development across various economies/ geographies, methodological approaches used, behavioral and theoretical aspects investigated, and finally, develop a taxonomy based on identified theses in the field of study. The study highlights that developed countries focus more on studies on the Sustainable IT-IS domain compared to other economies. It was evident that sustainable IS has received very limited focus. The study identifies 7 major themes and 29 subthemes forming the area of study during the evolution of Sustainable IT-IS through Green IT-IS. Subsequently, taxonomy was proposed to identify future research initiatives for investigation. The review comparing the evolution of research on managerial issues on Sustainable IT-IS vis-à-vis Green IT-IS is provided perhaps for the first time. The study provides an avenue for future research in the upcoming domain of Sustainable IT-IS.

  • In 2004, India began investing in the clinical trial industry; the country now boasts a 20% market share with the help of a valuable resource - the world's second largest population. The Contract Research Organization has been able to generate profits efficiently conducting clinical trials via a large pool of participants, skilled researchers, and reduced developmental costs. As the demand and sheer number of global clinical trials increased, the International Council of Harmonization-Good Clinical Practice was introduced, and the need for the Institutional Review Board increased. While the clinical trial industry in India boomed, it came at the expense of the participants' civil rights. The increased media attention regarding the ethical issues forced the Indian Supreme Court to take action. Consequently, India is the only country, by law, that specifically compensates participants suffering from injury directly resulting from participation in clinical trials. This research paper will describe and compare the relevant laws of India and Korea including compensation criteria. In addition, the ethical issues and aspects of indemnity in clinical trials will be discussed. While the clear advantage of the compensation is one of the protected rights of a clinical subject, the current system is not perfect. Furthermore, laws created to redeem ethical issues can have unintended, negative consequences.

  • The purpose of this study is to report the research trends of Korean medicine treatment for alopecia areata. We investigated the studies on Korean medicine treatments for alopecia areata via searching 4 web databases of Korea. 13 papers were selected, and we classified them according to publication year, published journals, the types of study, research subject, the methods of treatment, confirmation of recurrence, methods of evaluation, and institutional review board(IRB). We analyzed a total of 13 clinical studies of Korean medicine on alopecia areata based on various criteria and reviewed the research trends. Based on this, we suggested points to be improved and supplemented when conducting clinical research on alopecia areata in the future. Clinical studies on alopecia areata started to be published in 2001, and acupuncture, pharmacopuncture, herbal medicines, etc. were used as treatment methods for alopecia areata. Most of the clinical studies on alopecia areata were case studies, so it is thought that various types of clinical studies are needed. In addition, it is necessary to confirm the recurrence of alopecia areata and to improve the awareness of research ethics.
