This paper investigates the spillover effects(co-movements) between korean and U.S stock market by KOSPI and DJIA Index. Especially it compare to the pre- and post period of U.S. financial crisis resulted from sub-prime mortgage loan. The main results are as follows. First, the spillover effects of DJIA(U.S. market) to KOSPI(Korean market) are strong. This result accord with the former researches on this subject. Second, spillover effects are more strong after U.S. financial crisis. A possible reason for this phenomenon is a trend which the major investors such as foreign and institutional investors in domestic stock market have more attention to U.S. stock market. Third, the spillover effects appear in the opposite direction, that is KOSPI(Korean Stock Market) to DJIA(U.S. Stock Market). It seems to be the results of asian stock market's growing infIuences to European and U.S Markets.

본 연구는 경제위기시 환율의 신뢰구간 예측 알고리즘을 개발하는 것을 주된 목적으로 한다. 경제위기시 환율의 움직임의 특징은 평상시에 비해 변동성이 극도로 증가한다는 점이다. 본 연구에서는 이러한 변동성을 효율적으로 추정하기 위해 시계열 데이터의 변동성 추정에 유용한 것으로 알려진 블록 붓스트랩 기법을 사용하여 그 유용성을 보인다.

The paper does researches and analysis on the process of marine oil spill crisis response (MOSCR), and develops the marine oil spill crisis response simulation exercise system. The system developed by this paper is composed of four subsystems, including the training system of MOSCR, the geographical information system of MOSCR, the marine oil spill control and cleanup decision-making expert system, and the computer simulation exercise system. The paper builds up the applied model system of MOSCR. The system takes the marine oil spill crisis response geographical information system as the platform, which integrates all aspects of MOSCR. This system can offer an oil spill scene to the trainees and simulate the whole process of MOSCR on the interface of GIS.

This study attempts to show the reasons why the academic field, which has been called 'Library and Information Science', should change its paradigm for both research and practice. To this end, this study investigates the essence of the current academic crisis, which is seriously threatening the survival of the LIS as an independent academic field in South Korea. In details, this study discusses the identity problem of the LIS, the poverty in scholarship, the low self-esteem of the profession, etc. Also investigated are the reasons why the profession, which includes both scholars and practitioners, is facing with such a crisis. This study emphasizes that both researchers and practitioners in the LIS field should keep their eyes on the ongojng information revolution, and that in order to thrive as well as to survive from the midst of such an academic crisis they should notice and understand the essence of the revolution. The conclusion of this study includes the philosophies and strategies for survival, which the profession should keep in mind and follow in a hurry.

미디어 빅뱅이란 말이 나올 만큼 미디어가 폭발적으로 늘어나고 있다. 하지만 정작 저널리즘은 위기를 맞는 역설적 현상이 나타나고 있다. '사람들(수용자)이 자유로워지고 자신을 스스로 통제하는 데에 필요한 정보를 제공하는' 저널리즘의 목적에 비추어 볼 때, 저널리즘의 위기는 곧바로 '수용자 복지'의 훼손으로 귀결된다. 따라서 저널리즘 위기의 실체를 정확히 규명하는 일이 저널리즘의 공공성을 확보할 수 있는 선행과제다. 이 논문은 저널리즘의 존재 원칙에서 진실과 공정을 기본윤리로 개념화하고, 한국 저널리즘이 얼마나 그 기준에 부합하는지를 분석했다. 그 결과 우리 시대가 풀어가야 할 주요 의제에 대해 한국 저널리즘은 진실과 공정의 기본 윤리조차 지키지 않고 있음을 확인했다. 저널리즘 위기의 실체를 근본적으로 '존재 원칙의 위기'로 규명한 뒤 이를 극복하기 위한 방안을 제시했다. 미국의 '저널리즘을 걱정하는 언론인위원회'의 연구를 소개하며, 한국 언론학계가 언론 단체와 유기적 결합을 통해 저널리즘 살리기에 나설 것을 제안했다.

Purpose - This paper explores the determinants of bank lending to firms during and after the global financial crisis using firm- and bank-level data to answer the questions what caused the contraction of lending to firms despite the loosening monetary policy during this crisis period. Research design, data, and methodology - We investigate the effects of the monetary policy that followed the global financial crisis on firms borrowing. We use a dynamic panel model to address how firms lending respond to monetary policy. The data are obtained from CRETOP and we consider the manufacturing sector for the analysis to control for unobserved heterogeneity such as industry-specific shocks. Results - The findings from the empirical analysis suggest that both bank- and firm-level characteristics are significant determinants of bank lending. Especially, we find that corporate risk, measured by default risk, is one of the key factors that led to a decline in lending during the crisis. Conclusions - This paper shows that companies borrow more from liquid banks, and high bank capital can also contribute to an increase in a firm's borrowing from banks. Especially, the results confirm that the default rate measured at the firm level has increased during and after the global financial crisis, which implies that default risk interplays with other firm and bank-level characteristics.

Using a DCC - GARCH model analysis, this paper examines the existence of financial contagion from the U.S. stock market to the Vietnamese and the Philippine stock markets during the global financial crisis and the COVID-19 pandemic crisis. We use daily data from the S&P 500 (U.S.), VN-Index (Vietnam), and the PSEi (the Philippines). As a result, there is no evidence of contagion from the U.S stock market to the Philippine stock market that can be found during global financial crisis, while the Vietnamese market is influenced by this effect. Besides, both these developing stock markets (the Vietnamese and Philippine stock markets) are influenced by the contagion effect in COVID-19 pandemic crisis. Another finding is that the contagion effect during the coronavirus pandemic crisis in Vietnam is smaller than that during the global financial crisis, however, the opposite is the case for the Philippines. It is noticed that the Philippines seems to be more affected by the contagion effect from the COVID-19 pandemic than Vietnam at the time of this study. Because financial contagion is important for monetary policy, asset pricing, risk measurement, and portfolio allocation, the findings in this paper may give some useful information for policymakers and investors.

Persons with disabilities (PwD) are believed to be a group that had a greater risk during the pandemic. While PwD are vulnerable to the spread of COVID-19 due to their high dependence on physical contact, a series of policies restricting public movement during the pandemic had the potential to place PwD in increasingly marginalized situations. This situation reinforces the urgency of crisis communication as one of the critical parts of the COVID-19 response to ensure that all levels and groups of society can accept and understand the flow of information. Using a qualitative approach, this research was conducted through in-depth interviews with PwD age 17-50 in the city of Makassar, Indonesia. The results of this study suggest that crisis communication during the pandemic should involve participatory communication, which focuses on collaboration with empowerment. The PwD communities need to be actively engaged during the communication process of a pandemic crisis to ensure that inclusiveness is always taken into account. During the distribution of information, the relevant health officers or the government at the regional level need to carry out more frequent socialization and special services for PwD based on the characteristics of their disabilities.

본 연구의 목적은 본 논문의 목적은 최근 확산되고 있는 코로나바이러스감염증-19로 인한 위기를 국내 뉴스 빅데이터를 활용하여 규명하는 것이다. 본 논문은 COVID-19로 인한 위기와 관련된 언론기사들을 한국언론진흥재단의 뉴스 빅데이터 분석 시스템 '빅카인즈(BIGKinds)'를 활용하여 분석하였다. 본 논문에서는 약 10개월의 기간을 설정한 후, '코로나'와 '위기' 키워드를 중심으로 총 54개의 언론사의 관련기사들을 추출하였다. '코로나'와 '위기' 두 키워드 간의 상관계수를 파악하고, 연관어 분석을 통해 경제, 사회, 국제, 문화 각 대표 카테고리 별로 COVID-19로 인해 어떤 위기를 맞고 있는지 파악하고자 한다. COVID-19 사태는 경제, 사회 등 모든 부분에 큰 타격을 주고 있는 만큼 빅데이터를 활용한 본 논문은 COVID-19 사태 위기 극복을 위한 기초자료로 활용될 수 있을 것으로 기대된다.

한국 사회는 반복되는 경제위기설로 신음하고 있으며 한국에서 위기설은 실질적인 금융시장 폭락으로 전이되는 '자기실현적 위기' (self-fulfilling crisis)의 측면이 강하다. 그렇다면 한국에서 위기설은 왜 반복적으로 제기되고 있으며, 국민들은 이에 따른 정치, 경제적 고비용을 감수해야 할까? 이 연구는 이에 경제위기설이 진실에 대한 객관적 보도가 아닌 '진실효과'를 갖는 담론이라는 입장을 취했다. 그리고 이 담론의 역사성과 정치성을 확인하는 한편, 대안담론을 위한 실천적 함의를 찾고자 했다. 2008년 9월 위기설을 분석 사례로 정했고, 최종적으로 118개의 기사를 '도약기, 성숙기, 후퇴기'로 구분해 분석했다. 분석결과, 미디어담론은 경제현실의 변화에 따라 진화하기도 하지만 경제현실에 대한 언론의 정치적 입장에 따라 재구성되기도 하는 것으로 밝혀졌다. 그리고 언론의 이러한 재구성은 프레임의 전략적 활용, 시장에 대한 자의적 해석, 위기설에 대한 사후 평가와 같은 담론전략을 통해 실현되고 있었다. 연구진은 이러한 결과를 토대로 언론의 책임성과 전문성 제고 및 한국경제 현실에 대한 긍정적 재구성의 필요성을 제안했다.
