This batch experiment evaluated the impacts of major plant nutrient releases by applying the modified Hyperbola model on the leachates and N₂O emissions from incorporated rice hull biochar with organic fertilizer materials. The treatments consisted of the control as incorporated with organic fertilizer materials, the incorporated rice hull biochar with organic fertilizer materials, and the incorporated plasma-activated rice hull biochar with organic fertilizer materials under redox conditions. The results indicated that the maximum release amount of NH₄-N was 3486.3 mg L^-1 in the control, and their reduction rates of NH₄-N, NO₃-N, PO₄-P, and K were 8.0%, 17.5% 44.3.0% and 8.7%, respectively, relative to the control. In the control, the highest soluble amount of PO₄-P was 681.0 mg L^-1. The estimations for accumulated NH₄-N, NO₃-N, PO₄-P, and K-releases in all the treatments were significantly (p<0.01) fitted with a modified Hyperbola model. For greenhouse gas emissions, the lowest cumulative N₂O was 340.4 mg kg^-1 in the soil incorporated with plasma-activated rice hull biochar, and the reduction rates were 27.8% and 86.4% in the rice hull biochar and plasma-activated rice hull biochar treatments, respectively, compared to the control. Therefore, it concluded that the incorporated rice hull biochar can be especially useful for controlling PO₄-P release and N₂O emissions for bio-fertilizer applications.

This study aims to clarify the nature and properties of multimedia interface design, and to identify direction of multimedia interface design research. It also focuses on forecasting boundaries and major trends in current researches on multimedia interface design. The two jargons, 'interface' and 'interaction', are distinguished clearly to show the definition and boundary of multimedia interface. The multidisciplinary nature of multimedia interface design is identified as a result of examination and analysis on major researches. Nine research cases have been selected and categorized into two directions as the theoretical approach and the technical approach. Major characteristics of each case are examined in terms of subjects and methodologies. Findings on current states of the multimedia interface design research are: $\circled1$increasing importance of contextuality; $\circled2$emerging tendency for perceiving the content as one of interacting subjects; $\circled3$providing idiomatic interface context; and $\circled4$paying much attention to the meaning of minor actions. Those findings can be possible as a result of expansion of boundary of multimedia content with rapid distribution of multimedia in recent years. The study concludes that further researches can be activated on the basis of the concept of content-based multimedia interface.

Background: The paradigm of tonsillectomy has shifted from a treatment of recurrent throat infection to one of multi-discipline management modalities of sleep-disordered breathing (SDB). While tonsillectomy as a treatment for throat problems has been performed almost exclusively by otorhinolaryngologists, tonsillectomy as a part of the armamentarium for the multifactorial, multidisciplinary therapy of sleep-disordered breathing needs a new introduction to those involved in treating SDB patients. This study has its purpose in sharing a series of tonsillectomies performed at the Seoul National University Dental Hospital for the treatment and prevention of SDB in adult patients. Methods: Total of 78 patients underwent tonsillectomy at the Seoul National University Dental Hospital from 1996 to 2015, and 23 of them who were operated by a single surgeon (Prof. Jin-Young Choi) were included in the study. Through retrospective chart review, the purpose of tonsillectomy, concomitant procedures, grade of tonsillar hypertrophy, surgical outcome, and complications were evaluated. Results: Twenty-one patients diagnosed with SDB received multiple surgical procedures (uvulopalatal flap, uvulopalatopharyngoplasty, genioglossus advancement genioplasty, tongue base reduction, etc.) along with tonsillectomy. Two patients received mandibular setback orthognathic surgery with concomitant tonsillectomy in anticipation of postoperative airway compromise. All patients showed improvement in symptoms such as snoring and apneic events during sleep. Conclusions: When only throat infections were considered, tonsillectomy was a procedure rather unfamiliar to oral and maxillofacial surgeons. With a shift of primary indication from recurrent throat infections to SDB and emerging technological and procedural breakthroughs, simpler and safer tonsillectomy has become a major tool in the multidisciplinary treatment modality for SDB.

Purpose: At the time of consensus on the necessity of appropriate guidelines for health care facilities suitable for Korea, the paper aimed to analyze the characteristics in the aspect of the system of the US Health Care Facility Guidelines(FGI Guidelines) and to suggest implications. Since the system is significant for the guidelines to be socially accepted and operated, this study focuses on the system. Methods: Literature studies focusing on the analysis of prior studies and the 2018 edition of the FGI Guidelines were conducted. Results: As a result of reviewing the history and outline of the FGI Guidelines, the derived characteristics of the system were governance, procedure, and composition. First, it had multi-layered organization and multidisciplinary members. Secondly, the focus is on the procedure of gathering opinions from industry and the public. Third, the Guidelines have been continuously evolving to reflect the needs of the times and changes in the medical environment, and the content framework and method of writing are user-friendly in order to prevent confusion caused by vast contents. Implications: First, we need to consider the composition of a private organization to prepare Korean health care facility guidelines. Second, it needs a system that can induce the participation of multidisciplinary experts. Third, a comprehensive and user friendly guideline needs to be constructed.

Debates continue to multiply on the definition and rationale of Southeast Asia as a region and on the utility of the multidisciplinary field of area studies. However, we have now entered a post-colonialist, post-Orientalist, post-structuralist stage of reflection and re-orientation in the era of globalization, and a strong tendency on the part of insiders to pose these issues in terms of an insider-outsider dichotomy. On the one hand, the study of Southeast Asia for researchers from outside the region has become fragmented. This is for very obvious reasons: the strengthening and re-energizing of academic disciplines, the increasing popularity of other non-regional multidisciplinary studies, and the entry of globalization studies into our field of vision. On the other hand, how has the local Southeast Asian academy addressed these major issues of change in conceptualizing the region from an insider perspective? In filling in and giving substance to an outsider, primarily Euro-American-Australian-centric definition and vision of Southeast Asia, some local academics have recently been inclined to construct Southeast Asia in terms of the Association of Southeast Asian Nations (ASEAN): a nation-state-based, institutional definition of what a region comprises. Others continue to operate at a localized level exploring small-scale communities and territories, while a modest number focus on sub-regional issues (the Malay-Indonesian world or the Mekong sub-region are examples). However, further reflections suggest that the Euro-American-Australian hegemony is a thing of the past and the ground has shifted to a much greater emphasis on academic activity within the region. Southeast Asia-based academics are also finding it much more important to network within the region and to capture, understand, and analyze what Chinese, Japanese, and Korean scholars are saying about Southeast Asia, its present circumstances and trajectories, and their increasingly close involvement with the region within a greater Asia-Pacific rim. The paper argues that the insider-outsider dichotomy requires considerable qualification. It is a neat way of dramatizing the aftermath of colonialism and Orientalism and of reasserting local priorities, agendas, and interests. But there might be a way forward in resolving at least some of these apparently opposed positions with recourse to the concepts of culture and identity in order to address Southeast Asian diversities, movements, encounters, hybridization, and hierarchies.

The necessity of convergence education is more emphasized based on the education policy for fostering creative men of talent. Inside universities, however, programs for training talented individuals are still at primary stage. Universities understanding the importance of convergence education and thus founding some major fields of convergence studies have experienced hosts of troubles. The paper discusses the necessary plans of supports from the government and the university to activate the convergence education in accord with the social demands. Twenty-eight professors in engineering colleges participated in the survey for reviewing the required factors for the convergence education. In addition, structured interviews were carried out with three specialists working in industry and academic area of convergence technology. The study could suggest the following activation plans based on the government supports: (1) establishing a support center of convergence education, (2) founding a major field of convergence, (3) developing curriculums and curriculum subjects, and (4) hosting related conferences and forums. Also, the study could suggest the following activation plans based on the university supports: (1) developing special programs on convergence education in accord with the industrial demands, (2) revising regulations and administrative systems more flexible for the convergence education, and (3) providing incentives to the participants in the convergence education.

Environmental professional education in Korea has been mostly concentrated on the scientific and technological approaches to environmental problems. Many undergraduate majors in environmental engineering or sciences are designed to produce more technical manpowers in environmental fields. Most graduate schools on the environment also place an emphasis on teaching the technical aspects of environmental problems. Some environmental administration related courses, such as environmental law, environmental administration, environmental policy, environmental economics, environmental impact assessments, etc. are partically reflected in some curricula of very limited graduate or undergraduate environment majors. However, teaching environmental administration related courses in science or engineering major institutions has not been successfully carried out so far because lack of interests in such courses by most students and the shortage of competent teachers as well. Furthermore, those courses are not widely accepted by the departments of law, political science, public administration, etc. because their major interests are not in the environment-oriented. Environmental problems cannot be solved by the technical approach along. They should be systematically dealt with through interdisciplinary or multidisciplinary approaches, including natural and social sciences covering all relevant disciplines. in this respect, undergraduate environmental education should preferably cover broader courses on the environment, and the education for environmental professionals, including environmental administration specialists, is preferably handled by graduate schools offering many specialty area courses. Education for environmental administration specialist at graduate level is urgently needed in order to supply the competent manpower at government, business, and private organization levels dealing with environmental administration related problem. This is a new challenging area and the education for such specialists will become more important in the near future than technical manpowers which we ate now concentrating on their education.
