  • The Honolulu Strategy is a framework document to address marine debris issue globally. The Fifth International Marine Debris Conference held in March 2011 and organized by NOAA and UNEP catalyzed the development of the Holonulu Strategy. Goals of the Strategy are to reduce the amount and impact of land-based, sea-based, and accumulated marine debris. A set of strategies for each goal were provided for education and awareness, legislation, and alternative technologies. The Strategy also lists indicators that could be used to evaluate outcomes of strategies. The adoption of the Honolulu Strategy by the international community has led the international organizations such as GPA, IMO, and CBD to strengthen their responses to the marine debris issue. UN has also set up specific actions that will be implemented until 2025 through its resolutions on marine debris. Recent global developments related to the marine debris issue might lead to a change in the character of the international marine debris management from the current soft law regime to a mandatory one. The Honolulu Strategy could provide a guideline when the Korean government formulates the Second Basic Plan for Marine Debris Management, especially with its prevention-oriented approaches, utilization of scientific policy development tools, and adoption of evaluation system using performance indicators.

  • The demand for fuel and energy resources continues to grow due to increased consumption and emerging economies in all parts of the world. With this increase in demand, crude oil prices in the international market has jumped dramatically. Global warming, which is a consequence of increasing greenhouse gas (GHG) emissions, has become scientific, social, and political concerns. To cope with global warming and energy crisis, cost-competitive biofuels are urgently needed. In addition, development of an infrastructure, which supplies energy stably and diversifies energy resources, as well as new cost-saving technologies should be developed to reduce the costs of producing biofuels. Due to high oleic acid content, rapeseed (Brassica napus L.) is currently the potential feedstock for biodiesel production in temperate zone region and the production and use of rapeseed oil is already commercialized in Europe. In Korea double-cropping (rice and rapeseed) became more prevalent because it reduces competitions from land constraints. Production of rapeseed as a biodiesel feedstock may reduce the influence of rising oil prices and nation's dependence on imported petroleum and increase job opportunities and farm incomes.

  • The needs for ecological engineering, which can design ecosystems that integrate human society and their natural environment for the benefit of both, has increased. The Korean Society of Ecology and Infrastructure Engineering (KSEIE) was established for this purpose and has contributed to the research and development of theories and technologies in related fields. However, the current state of educational services and contents of ecological engineering is still needed to be standardized and systematized. In this paper, we outlined the trends of ecological engineering education at international and domestic levels and proposed a sample services and curriculum, brought from the discussions and suggestions made during the forum, Founding the Education for Ecological Engineering, held by the KSEIE. Education of ecological engineering can nurture people who can design and manage ecosystems for the benefits of human and natural society and can restore ecosystems disturbed artificially. The services and curriculum have to meet and cover the challenges facing the future of ecological engineering; a. the ethical interpretation of the balance between human and nature, b. developing and strengthening its relationship with other scientific disciplines and societies - business, policy, education, and practitioners, c. identify and fuse the key ecological engineering principles into other discipline. We proposed a three layers curriculum system, basic (mathematics, physics, chemistry, biology, etc.), core (ecology, hydrology, engineering, etc.), and advanced subjects. The first two can belong to an undergraduate program and the last two can be put into graduate program. The selection of subjects is according to the purpose and needs of the major.

  • While science museums, whose functions consist traditionally in collecting, preserving, researching, and displaying science-related objects, present scientific knowledge, figures, or tools in the historical context, science centers give more emphases on science education by exposing interactive exhibits to their visitors. However, neither objects-oriented exhibits nor hands-on technologies can provide museum visitors with the full insight into modem science in terms of its complicated relationships to politics, economy, culture, art, risk, and environment. This paper argues that for the 21st century we need to establish a new kind of science museum through the critical examination of its previous kinds - science museums and science centers. In the first part of this paper, the history of the first and second generations of science museums, including their recent trends in science centers, in the West will be elaborated. Secondly, the development of national science museums in Korea will be discussed specifically for the understanding of Korean science museums. The next part of this paper will seek for the possibilities of the third generation of science museums through three examples, which show interdisciplinary, contextual, and institutional approaches to change science museums or science centers. Fourthly, the social function of science museums as 'forum' will be discussed in relation to promoting public 'participation' of science as well as public 'understanding' of science. As a conclusion, some practical suggestions and conceptual guidelines will be proposed for the future Korean national science museum.

  • In these days of severe struggle for existence, the world has changed a great deal to global and digital oriented period. The enterprises try to introduce new management and production system to adapt such a change. But, if the only new technologies are applied to an enterprise without definite analysis about manufacturing, failure fellows as a logical consequence. Hence, enterprise must analyze manufacturing system definitely and needs new methodologies to mitigate risk. This study suggests that the new approach, which is systems approach for process improvement, is organized to systems analysis, systems diagnosis, and systems verification. Systems analysis analyzes manufacturing systems with object-oriented methodology-UML(Unified Modeling language) from a point of product, process, and resource view. Systems diagnosis identifies the constraints to optimize the system through scientific management or TOC(Theory of constraints). Systems verification shows the solution with virtual manufacturing technique applied to the core problem which emerged from systems diagnosis. This research shows the artifacts to improve the productivity with the above methodology applied to forming shop. UML provides the definite tool for analysis and re-usability to adapt itself to environment easily. The logical tree of TOC represents logical tool to optimize the forming shop. Discrete event simulator-QUEST suggests the tool for making a decision to verify the optimized forming shop.

  • The Total Pollutant Load Management System(TPLMS) in the Han River basin is being changed from a voluntary to a mandatory system. Accordingly, this study suggests directions and priorities for research that can support implementation of TPLMS through an objective approach that deploys gap analysis and analytic hierarchy processes (AHP). Gap analysis indicated that TPLMS in Korea is still focused on compliance with regulations, and that implementation of TPLMS is still in its early stage. Improvements are thus needed in flexibility and effectiveness, including introduction of emissions rights trading, and upgrading to a renewable emissions permit system. The AHP study indicated that R&D will need to proceed in parallel in multiple areas to improve systems and resolve scientific uncertainties. Balanced R&D will be needed in both the institutional and technical groups. Subgroup analysis indicated that developing a reasonable process to establish water quality management targets is of the highest priority in the institutional group. In the technical group, higher priority will need to be given to improving model reliability and developing innovative pollution load reduction technologies.

  • Objectives : Currently, it is being reported that new health technology (HT) is introduced and spread throughout Korea at a very fast rate. However, the current status of new HT related to dentistry has not been known or studied. Therefore, this study aims to understand the present state and awareness on dentistry-related domestic new HT via surveys and research, and thus apply this as a reference to construct an effective new HT-related system in the field of dentistry. Methods : The assessment status of New Health Technology Assessment (nHTA) committee was searched on the website for any updates on new HT5). The cases were searched in the range between Jan 1 2012 and Jul 31 2016 by submission date and were analyzed by year, division of technology, progress and major operating practitioner. Among those, technologies utilized by dentists were additionally analyzed. The survey result was obtained by combining responses of 25 participants from the workshop for new HT application and 11 members of Korean Association of Oral and Maxillofacial Surgeons (KAOMS). The workshop was co-hosted by KAOMS and Clinical Translational Research Center for Dental Science (CTRC) under Seoul National University Dental Hospital (SNUDH). Results : Most of the respondents to the survey have heard of new health technology but were unaware of the application procedure. 'Safety and effectiveness' was selected the most for things to consider when introducing new HT, followed by 'scientific evidence of the technology.' For new dental HT status, submissions between 2012 and Jul 31 2016 were analyzed by major operating practitioner, including cases where there are multiple practitioners. Yet, only 19 cases (17 %) of dentists were reported. Among 385 cases approved by nHTA, only 2 cases included dentists. Conclusions : Active publicity by the government on new HT and its application procedure, and continued interest and research in the dental and medical community is likely to be required for the development of dentistry.

  • Due to its unique formation and mystery phenomena, comets is a major motif that inspires various creative fields. Media art that has been developed and expanded in step with the development of modern scientific technology has expressed the unique characteristics of comets such as their structure in the art as a motif, using technologies. This study describes the process of producing "Near by", an distance-recognition interactive media art. offering the audience a chance to create a tail of a comet as they close to it. changes the color of a LED structure representing the nucleus of a comet as the audience approaches it. At the same time, a video of a comet's tail is projected. Through this interaction, the audience will renew their perception on comets and emotionally interact with the art. This work capturing not only the formative characteristics of a comet, but also its forming process as a motif. Such composite way of expressing a motif could be presented as a possibility of extending the expression of the natural phenomenon in the future media art field.

  • Functional Magnetic Resonance Angiography (fMRA) was a technoscientific innovation that allows scientists to directly view the changes made in the blood vessels of a brain. fMRA was first developed at Neuroscience Research Institute (NRI) in Korea. fMRA mainly utilizes 7 Tesla MRI technology, and NRI is equipped with the instrument. First article on fMRA was published in 2008, and two more papers in 2010 and 2012 consecutively had been published on the newly developed technique. However, fMRA is a competitive technology with existing fMRI. Both techniques capture microvascular changes in a brain, and by doing it, both techniques visualize the cognitive and affective changes. fMRI technology was introduced by Seiji Ogawa in the early 1990's and has been widely used since then. In contrast, fMRA was a newer technology and rather unknown. Developers of fMRA in NRI used series of signifiant-politics in order to make it better known to scientific community as well as public. By resetting the boundaries of existing concept of fMRI, they tried to lower the threshold of a new concept/technique. This case study shows how technoscientists use semiotic strategies governing new technology.

  • As the digital technologies and internet have advanced, data have centered in the process of meaningful scientific ramifications and policy making in a wide variety of fields. Data curator in charge of managing data plays a significant role in terms of improving the effectiveness and efficiency of data management and re-uses. The purpose of this study is to identify the core competencies for data curator. For achieving the purpose of this study, two sets of data were collected. First, a total of 255 job descriptions were collected from the web sites including ARL, Digital Curation Exchange, Code4lib, ASIS&T JobLine for the period of 2011-2014. Second, in-depth interviews with five data curators from four diverse organizations were collected. The two sets of data were analyzed into seven categories identified from the related studies. Findings of this study showed that core competencies for data curator were identified into four categories, communication skills, data management techniques, knowledge and strategies for data management, and instructions and service provisions for users. The implications of this study can be considered as integrated and professional curriculum developments for data curator with core competencies.
