The recent computational revolution of Bayesian statistics has expanded use of the Bayesian statistics significantly; however, Bayesian statistics face a new set of challenges in the era of information technology. We survey the history of Bayesian statistics briefly and its expansion in the modern times. We then take a prospective future view of statistics and list challenges that the statistics community faces.

With the appearance of the climate change concerns, energy transition to renewable energy is accelerating over the world. Korea, a latecomer to the renewable energy sector, has also been unable to avoid energy transition. The government is promoting strong goals for expansion of renewable energy. However, switching from stable and controllable conventional generation to intermittent and uncontrollable renewable generation will be a big challenge for the electric power industry. Korea Power Exchange(KPX), which is responsible for the planning and operation of the electric power industry in Korea, is trying to improve measures in various fields such as the implementation of real-time unit commitment and additional real-time markets in order to cope with the volatility and intermittency of renewable energy.

Web 2.0 환경에서 CBL 교수 모형은 유의미한 교수모형으로 등장하고 있다. CBL 교수 모형은 Google, Wikipedia 등 대용량 데이터베이스와 Wikispaces, Voice Thread, Twitter 등 다양한 Web 2.0 도구를 활용하여 학생들이 주도적으로 도전과제를 탐구하고 해결하는 교수 모형이다. 본 논문에서는 Web 2.0 환경에 적합한 교수 모형인 CBL의 개념 및 중요 구성요소 그리고 CBL 수업을 위한 환경구축에 대해 살펴보고 CBL Lesson plan 및 초등학교 교과교육에 CBL 교수모형을 적용한 예시를 소개하고 CBL를 초등학교에 적용하기 위한 고찰을 하였다.

단백질 분류는 현대 생물학의 큰 도전과제이다. 현재 여러 단체에 의해 잘 관리되는 상세한 주석이 달린 많은 양의 단백질 정보들이 존재한다. 이러한 데이터베이스의 덕분으로 다양한 물리 화학적 특성과 주석들에 기반하고 있는 분류 기법들이 연구되고 있다. 특히 아미노산들로 이루어진 단백질 서열이 해당 단백질의 분류에 중요한 역할을 하는 진화적 기록들의 단서가 되기 때문에 단백질 서열들에 대한 연구가 활성화되고 있다. 비록 단백질 서열이 단백질 분류 문제의 중요한 특징이 된다고 해도 단순한 단백질 서열만으론 해당 단백질에 대한 충분한 정보를 얻을 수 없으며, 타 종 간에도 기능상 유사성 때문에 서로 비슷하게 판별될 수 있다. 이러한 문제점에 착안해서 우리는 오토마타 종 분류기라고 부르는 새로운 시스템적인 종 분류 접근 방법을 제안한다. 이 시스템의 클러스터링과 종 분류 판별 성능에 대한 평가 실험을 수행해본 결과 상대적으로 좋은 성능을 얻을 수 있었다.

서북태평양은 전세계적으로 태풍이 가장 많이 발생하는 해양 지역 중 하나이다. 태풍이 몰고 온 강풍과 폭우, 폭풍해일 등은 우리 사회경제와 환태평양 국가의 신변안전에 심각한 위협이 되고 있다.특히 내륙으로 진입하는 수백킬로의 영향을 미치는 만큼 넓은 지역에 걸쳐 강우량이 발생하고, 집중강수 기간이 짧아 산사태 등 자연재해로 많은 인명피해가 발생한다. 이러한 피해를 줄이기 위해서는 태풍의 활동특성을 잘 파악하고 태풍에 의한 강수량 예측 연구가 재해예방과 재난저감을 위해 필요하다. 그러나 현재기술에서 태풍이 몰고 온 강수의 정확한 양적 예측은 여전히 어려운 문제이며, 해결해야 할 큰 도전과제이다. 본 연구에서는 태풍별 강수량 상관관계를 분석하고, 서북태평양의 역사적 태풍의 궤도와 강도를 고려해 태풍으로 인한 강수량을 예측하는 통계적 방법을 적용한 결과를 제시하고자 한다.

The purpose of this study is to review what we have done and to identify what we have to do to be successful with Web archiving which is important to preserve our cultural heritage for the next generation. Some characteristics of Web resources as information sources were identified and some difficulties with Web archiving were discussed. The outcome of national and/or international Web archiving projects including Kurturarw3, PANDORA and Internet Archive were reviewed. Policy issues and technological problems of Web archiving we have to solve were listed.

For Singapore, 2017 was an uneasy year. The presidential election was fraught with controversy since the revised Presidential Election Act allowed only one candidate to be eligible for the election. The bitter feud between Prime Minister Lee Hsien Loong and his siblings shocked many Singaporeans. Succession planning for the next top leadership is still veiled in obscurity. The anti-globalization trend and the increasing pressure to raise the tax have become major challenges for Singapore's economy to overcome. China's continuous diplomatic pressure has called into the question Singapore's pragmatic foreign policy. Although its relations with China were back to normal, Singapore, the ASEAN chair in 2018, is still facing intractable problems in safeguarding ASEAN centrality in the growing US-China rivalry. In the meantime, Singapore has pursued its diversity and equality, heading toward a more matured multi-racial and multi-cultural society in 2017. The first female president, Halimah Yacob, served as a symbolic epitome of Singapore's emphasis on diversity and harmony among different ethnic groups and minorities. This great milestone, however, has largely been questioned by Singaporeans, as it seemed to be a political gesture that only utilized Halimah's double minority in the level of ideologies. The election of the Malay president has led Singaporeans to think about the real equity and equality among minorities, while strongly motivated to move toward a more inclusive society. In 2018, Singaporean leaders will try to resolve many challenging problems by reaffirming leadership succession planning, which is expected to lead Singapore to pursue a more integrated society.

The purpose of this study was to investigate the enhancing creative competency and changes in academic challenge for the pre-service teachers. For this purpose, 94 pre-service teachers participated in project learning through the preparation of the convergence instruction and the class demonstration during one semester. The pre and post questionnaire survey was conducted the measurement of creative leader competence and K-NSSE for academic challenge. Analysis of data was performed using the IBM SPSS 18.0 program for the corresponding sample t test. The creative competency included 'higher mental thinking', 'problem solving', 'curiosity', 'sensitivity' 'task commitment', 'the pursuit of social value', and 'co-operations and considerations'. This results was significant(p< .05). Academic challenge, high-order learning domain and learning strategies domain were significant(p< .05). Based on this, in order to generalize the convergence education and convergence lesson, it is necessary to design various convergence lessons and practice study to make a plan and practice it. In addition, the implications for the necessity of correcting and supplementing the effects after repeated convergence lessons were discussed.

Remarkable scientific and technological achievements are mainly shown in the 'super-convergence' or 'convergence of convergence' among cross- disciplinary fields, and advanced countries are promoting the 'high-risk, high-return research' ecosystem. Google LLC is carrying out numerous new challenges in terms of a non-failure perspective. Innovative research by the US Defense Advanced Research Projects Agency (DARPA) has produced such breakthroughs as the Internet, GPS, semiconductors, the computer mouse, autonomous vehicles, and drones. China is pioneering a 'Moon Village' and planning the world's largest nuclear fusion energy and ultra-large particle accelerator project. Japan has also launched 'the moonshot technology development research system' to promote disruptive innovation. In Korea, the government is preparing a new research program to tackle the global scientific challenges. Therefore, it is necessary to determine the reasonable geoscientific challenges to be addressed and to conduct a preliminary study on these topics. For this purpose, it is necessary to conduct long-term creative research projects centered on young researchers, select outstanding principal investigators, extract innovative topics without prior research or reference, simplify research proposal procedures, innovate the selection solely based on key ideas, and evaluate results by collective intelligence in the form of conferences.
