FDI World Dental Federation is organization representing more than one million dentists worldwide with its more than 100 years of long history. Now FDI headquarter is located in Geneve, Switzerland and serves for developing health policy and continuing education programs, speaking as a unified voice for dentistry in international advocacy and supporting member association in oral health promotion activities worldwide. Korean Dental Association has been a member of FDI since 1959 and participated actively in the FDI's worldwide activities. Past Dr. Heung-Ryul Yoon was a president of FDI from 2003 for 2 years and we also have an experience in 1997 of hosting FDI Annual World Dental Congress successively in Seoul. The image of a country reflects the country's culture as well as affects to its economical and social development and it decides the national brand toward the world. Currently, Korean people realized that and put their efforts for promoting diverse aspects of Korea to the world such as multimedia culture called Han-Ryu, electric industry, automotive industry, sports represented by soccer. We have advanced technique and skill in various fields and now it's time to show ourself better to the world. It's same to the dentistry. It's true that Korean dentistry is top-class in the world and the dental industry is prosperous and also has best technique in the world. I think and strongly hope that the 2013 FDI Seoul Annual World Dental Congress would be best opportunity for Korean dentistry and dental industry to promote ourselves and make a big step to the world. Not only for the dentistry, it will also be very good chance to all the Korean people to improve Korean national brand. I believe that we can accomplish if we, all dental societies, stand together and join our effort to use this good chance the best. I know we can make it.

빅데이터 기술의 발전에 따라 여러 분야에서 빅데이터의 필요성이 증가하고 있다. 그중 최근 의료 산업은 치료 중심에서 예방과 건강관리 중심으로 변화됨에 따라 질병 발생 가능성 예측 및 개인 맞춤형 의료 서비스의 중요성이 증대되고 있다. 이를 위해서는 개인의 생체정보를 수집할 수 있는 디바이스와 수집된 데이터를 분석할 빅데이터 시스템이 필요하다. 본 논문에서는 저가형 웨어러블 디바이스를 이용한 생체정보 빅데이터 시스템을 설계하였다. 웨어러블 디바이스는 심장 박동수와 걸음 수, 활동량 등의 기본적인 생체정보를 획득할 수 있는 Mi Band를 이용하였고, 수집된 생체정보는 MongoDB를 이용하여 NoSQL 형식으로 저장한 후 분석하였다. 본 연구의 결과를 기반으로 차후에는 Hadoop 등을 사용하여 실제 의료 환경에서 사용이 가능한 빅데이터 시스템을 구축하고 다양한 의료 정보용 웨어러블 디바이스와 연계하여 실제 의료 서비스에서 사용이 가능할 수 있다.

AI(Artificial Intelligence)의 다양한 모델 중 생성 모델, 특히 GAN(Generative Adversarial Network)은 이미지 처리, 밀도 추정, 스타일 전이 등 다양한 응용 분야에서 성공을 거두었다. 이러한 GAN은 CGAN(Conditional GAN), CycleGAN, BigGAN 등의 방식으로 확장 및 개선되었지만 재난 시뮬레이션, 의료 분야, 도시 계획 등 특정 분야에서는 데이터 부족과 불안정한 학습에 의한 이미지 왜곡 문제로 실제 시스템 적용에 문제가 되고 있다. 본 논문에서는 클래스 항목을 판별하는 ACGAN(Auxiliary Classifier GAN) 구조를 기반으로 기존 PGGAN(Progressive Growing of GAN)의 점진적 학습 방식을 활용한 새로운 점진적 단계의 학습 방법론 PST(Progressive Step Training)를 제안한다. PST 모델은 기존 방법 대비 70.82% 빠른 안정화, 51.3% 낮은 표준 편차, 후반 고해상도의 안정적 손실값 수렴 그리고 94.6% 빠른 손실 감소를 달성한다.

본고에서는 에너지 사용량 절감 및 효과적인 에너지 사용을 위한 에너지 기술과 정보통신기술(ICT)의 융합에 대해 서술한다. 전 세계적인 에너지 사용량 증가 추세에 대응하기 위하여 많은 연구가 진행되어왔으나, 이들 중 많은 부분은 에너지 생산, 소비, 전달 단계에서 사용하는 장비 자체의 효율 증가를 목표로 하고 있다. 에너지 절감을 위한 ICT 적용은 획일화된 연구 방향에서 벗어나 기존에 고려 대상이 아니던 분야에서의 에너지 절감을 기대할 수 있다. 에너지 기술과 ICT의 융합을 통한 빅데이터 서비스 제공은 대량의 에너지 및 환경 데이터 연계 분석을 가능하게 한다. 빅데이터 분석을 통해 연관성이 불분명하던 데이터 간의 경향성을 찾아내는 것은 새로운 에너지 절감 방안 모색에 도움이 되며, 나아가 새로운 비즈니스 모델 개발로 이어질 수 있다. 본고는 에너지 기술과 ICT의 융합을 통해 빅데이터 서비스를 제공하는 실제 기업 및 프로젝트 사례들을 소개하는 것을 목적으로 한다.

본 연구는 근대5종 세계대회 데이터베이스에서 2015년부터 총 5년간의 공식 세계기록을 수집하여 사격 유형 및 특성이 기록에 미치는 영향을 밝혀내고자 했다. 이를 위해 UIPM Level 1 대회인 월드컵, 세계선수권대회 출전한 남녀 모든 선수에 대해 전체 사격 격발 경우를 분석하였다. 연구결과 왕복횟수와 차수가 늘어날수록 사격누적기록이 나빠지는 양상을 보였고, 1번째 왕복 3차 사격에서 가장 좋은 기록을, 4번째 왕복 5차 사격에서 가장 나쁜 기록이 나타났다. 또한, 첫발의 성공 유무에 따른 누적사격기록 편차 값은 왕복횟수가 늘어남에 따라 9%가량 편차가 증가하는 경향성이 나타났는데 이는 시간이 지남에 따라 첫발의 성공은 더욱 중요하며 근대5종 사격 시 첫발 명중만으로 기록단축에 큰 효과를 거둘 수 있다. 이러한 연구를 바탕으로 사격 정확성에 영향을 미치는 요인 및 특징을 밝히고, 복합경기 특성에 맞게 육상기록과 연계한 후속 연구가 필요하다고 사료된다.

Purpose - The purpose of this paper is to briefly review the contemporary global environment to suggest and develop appropriate strategies for KODISA and its journals. Research design, data, and methodology - This is an analytical case study that examines KODISA and its journals and the contemporary environment to demonstrate the importance of developing the future goals. Results - The analysis indicates that KODISA and its journals must decide whether to follow same footsteps of many reputable and big academic associations and journals or to start focusing more on the welfare of the public as an academic institution. Researches and scholarly works should be shared with everyone, and practicality and relevancy of researches should be valued and applied for the general welfare. Conclusions - Based on the progress and current success of KODISA and its journals, their goals should not be limited to just becoming a world renown academic association or journals. Promoting the welfare of the public through researches and scholarly activities should be their ultimate goal as an academic institution and journals. Attracting more practitioners and producing more researches that are practical and applicable to the public would be the first step while maintaining the quality and rigor of their academic and scholarly activities, which include publication practices.

Nowadays, the transportation of almost all cargoes depends on sea routes in international trade. In the transaction of trade, cargo transportation must be completed on the base of two contrary objectives, one of which is to protect the vessel, cargoes and crew aborad her safely through every step of the transportation and the other is to pursue profits from the transaction of the trade. In spite of the great development of the modern techniques in shipbuilding today, many sea disaters of big merchant vessels have been occurring successively in winter seasons every year on the sea routes of the North Pacific Ocean. Whenever the accident of losing a vessel in rough sea occurred , many experts of the country to which the vessel belonged had tried to take out the reason of the missing without manifesting the exact cause of the unhappy occurrence. In this paper, we calculated ocean wave status along the route of the North Pacific Ocean theoretically concluded by us as optimum on the basis of weather and sea conditions. In the calculation, we used ITTC wave spectrum formula and meteorological data of "Winds '||'&'||' Waves of the north Pacific Ocean" edited by Ship Research Institute of Japan on the basic data assembled by World Meterological Organization through past 10 years. We selected three sample vessels of most common size in the North Pacific Ocean Routes, a container, a log carrier and a bulk carrier and applied tree sample vessels to the calculated sea conditions for getting the rolling angles of the vessels and stress exerting on the hulls. Examining the calculated results, we concluded as follows; 1. Under the condition of these status7 by beaufort scale, "heave to" maneuvering is the best and safest way to steer every vessel. 2. The most dangerous part of sea area along the west bound optimum route of the North Pacific Ocean in winter season, is the southern sea area of the Kamchatka peninsula.a peninsula.

Nowadays, Genomic data constitutes one of the fastest growing datasets in the world. As of 2025, it is supposed to become the fourth largest source of Big Data, and thus mandating adequate high-performance computing (HPC) platform for processing. With the latest unprecedented and unpredictable mutations in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the research community is in crucial need for ICT tools to process SARS-CoV-2 RNA data, e.g., by classifying it (i.e., clustering) and thus assisting in tracking virus mutations and predict future ones. In this paper, we are presenting an HPC-based SARS-CoV-2 RNAs clustering tool. We are adopting a data science approach, from data collection, through analysis, to visualization. In the analysis step, we present how our clustering approach leverages on HPC and the longest common subsequence (LCS) algorithm. The approach uses the Hadoop MapReduce programming paradigm and adapts the LCS algorithm in order to efficiently compute the length of the LCS for each pair of SARS-CoV-2 RNA sequences. The latter are extracted from the U.S. National Center for Biotechnology Information (NCBI) Virus repository. The computed LCS lengths are used to measure the dissimilarities between RNA sequences in order to work out existing clusters. In addition to that, we present a comparative study of the LCS algorithm performance based on variable workloads and different numbers of Hadoop worker nodes.
