  • Biotechnology in the 21st century will be driven by three emerging technologies: genomics, high-throughput biology, and bioinformatics. These technologies are complementary to one another. A large number of economically important crops are currently subjected to whole genome sequencing. Functional genomics for determining the functions of the genes comprising the given plant genome is under progress by using various means including phenotyping data from transgenic mutants, gene expression profiling data from DNA microarrays, and metabolic profiling data from LC/mass analysis. The aim of plant molecular breeding is shifting from introducing agronomic traits such as herbicide and insect resistance to introducing quality traits such as healthful oils and proteins, which will lead to improved and nutritional food and feed products. Plant molecular breeding is also expected to aim to develop crops for producing human therapeutic and industrial proteins.

  • Three randomized control trials (RCTs), published in 2013, investigated efficacy of mechanical thrombectomy in large vessel occlusions and did not show better results compared to intravenous (IV) recombinant tissue-type plasminogen activator (tPA) alone. However, most clinicians treating stroke consider mechanical thrombectomy as the standard treatment rather than using IV tPA alone. This paradigm shift was based on five RCTs investigating efficacy of mechanical thrombectomy in acute ischemic stroke conducted from 2010 to 2015. They demonstrated that mechanical thrombectomy was effective and safe in acute ischemic stroke with anterior circulation occlusion when performed within 6 hours of stroke onset. There are four reasons underlying the different results observed between the trials conducted in 2013 and 2015. First, the three RCTs of 2013 used low-efficiency thrombectomy devices. Second, the three RCTs used insufficient image selection criteria. Third, following the initial presentation at the hospital, reperfusion treatment required a long time. Fourth, the three RCTs showed a low rate of successful recanalization. Time is the most important factor in the treatment of acute ischemic stroke. However, current trends utilize advanced imaging techniques, such as diffusion-weighted imaging and multi-channel computer tomographic perfusion, to facilitate the detection of core infarction, penumbra, and collateral flows. These efforts demonstrate that patient selection may overcome the barriers of time in specific cases.

  • Agricultural extension services in Korea are faced with increasing demands for more efficient production and managerial technology according to globalization and free trade system. At the same time, three steps of organizational restructuring in 1998 and 1999 resulted in decreased number of organization and manpower, thus, resulting confusion in implementing extension services. To cope with the international and national challenges, Korean agricultural extension services should try paradigm shift including the followings; 1. To establish identity of agricultural extension services in Korea through making laws and regulations in terms of concept, roles, principles. implementation and methods. 2. To implement vitalizations plan through enhancement of national extension service such as food production. raising local specialty products for domestic consumption and producing strategic agricultural products for export. expanding capability of rural women, increasing opportunity for management consultation, supporting digital technology information, and promoting morale and capability of extension educators. 3. To reform agricultural extension system through adjusting the functions of extension service of the Rural Development Administration, regionalizing city and county extension center to provincial level, and changing the status of directors of extension centers from city /county to national government.

  • Mid of 1980s witnessed the beginning of a new trend regarding the elderly as the Third Age Group, which is capable of positive selection for their later life. These changes are caused not only by the rising cost of caring them as the dependent to the society, but also by paradigm shift from the clinical and biomedical model to political economy and critical gerontology. The paradigm shift is based on the social constructionism as a perspective on the later life. In this communication the development of social constructionism is reviewed as an approach on the living environment for later life through literature survey. Emphases were made on the anti-ageism instead of ageism in the analysis of the social constructionism perspective for living environment in later life. Individual practice, influencing the practice of others, influencing agency policy, and developing theory were addressed and emphasized for the practice of anti-ageism. This study found the importance of the development of the social constructionism perspective on the study and practice regarding living environment for ‘the Third Age’ in Korean situation.

  • The recent medical education paradigm shift from teacher-centered to student-centered education, has led to a concentration on students' performance and competency. This means that a physician should be able to provide adequate health care in any real medical treatment situation. In order to reflect such a paradigm shift, The Catholic University of Korea School of Medicine launched a new curriculum in 2009 that emphasizes students' performance and competency-based education, known as "outcome-based education." In outcome-based education, the educational process is determined by the desired outcome, signifying the detailed competency that a graduating student should have. Thus, in outcome-based education, we should first determine the competency that results from adequate training and education, followed by specific teaching and learning strategies, methods, and assessment. This paper reviews how The Catholic University School of Medicine developed its new curriculum according to the development steps of outcome-based education.

  • Patient safety remains one of the most important health care issues in Korea. To improve patient safety, we have introduced concepts from the field of safety science such as the Swiss cheese model, and adopted several methodologies previously used in other industries, including incident reporting systems, root cause analysis, and failure mode and effects analysis. This approach has enabled substantial progress in patient safety to be made through undertaking patient safety improvement activities in hospitals that are systems-based, rather than individual-based. However, these methods have the shared limitation of focusing on negative consequences of patient safety. Therefore, the paradigm shift from Safety I to Safety-II in safety science becomes the focus of our discussion. We believe that Safety-II will complement, rather than replace, Safety-I in the discipline of patient safety. In order to continuously advance patient safety practices in Korea, it is necessary that Korea keeps abreast of the recent global trends and development in safety science. In addition, more focus should be placed on testing the feasibility of new patient safety approaches in real-world situations.

  • We are on the verge of paradigm shift for the design and operation of our urban water systems from treatment- and efficiency-based to recirculation- and sustainability-based. One of the most frequently suggested alternatives to embody this paradigm shift is to decentralize the currently highly centralized urban water infrastructure. However, claims for water infrastructure decentralization are often criticized due to poor economic feasibility, unstable performance, and unprofessional operation and maintenance. The current study critically reviews the literature to discuss the technical advancement needs to overcome such challenges. Firstly, decentralized water infrastructure was briefly defined and the rationale for the proposal of its introduction to the next-generation urban water systems was laid down. The main discussion focused on the following water technologies, which require special attention when working with decentralized water infrastructure: i) material collection, storage, and transport; ii) easily scalable water treatment; iii) sensor, information, and communications; and iv) system optimization. The principles, current development status, and challenges were discussed for each of the water technologies. The discussion on the water technologies has enabled the identification of future research needs for their application to the next-generation urban water systems which will be designed following decentralized water infrastructure. This paper will significantly improve the current understanding on water infrastructure decentralization and provides insight on future direction of water technology development.
