The Paradox of Rational Policies and Irrational Outcomes: A Case of Unexpected Policy Performance Caused by Information Delay

Chung, Ik Jae 서울産業大學校 1995 논문집 Vol.41 No.1

This study analyzes the impact of information network within the waste recycling market on the performance of public policies designed to develop the recycling market. Two typical policies are reviewed with an experimental procedure of partial and whole model tests. A System Dynamics model of waste recycling market is used as a laboratory setting for this study. The research findings suggests that will-intended policies can inadvertently lead to dysfunctional performance within a localized information environment. Delayed and distorted information feedback in the multi-stage structure of the recycling market further complicates problematic policy outcome, or market instability. This study proposes an information policy of integrating vertically the information network in the recycling market to improve the performance of market development policies.

정보사회의 불확실성 관리를 위한 정책 논리와 대응: 정보보안사고의 유형화와 대응책

( Ik Jae Chung ) 중앙대학교 국가정책연구소 2011 국가정책연구 Vol.25 No.4

정보보안에 대한 논의는 대체로 기술공학적 시각을 통해서 이루어지고, 새로운 보안기술개발이나 시스템 구축에 의한 하드웨어 차원에서 해결책을 찾고자 한다. 본 논문은 정보보안문제와 대응방안을 기술적 시각이 아닌 정책적 논리를 통해서 접근한다. 특히, 정보보안은 정보사회의 위험관리이며 위험에 내재한 불확실성을 최소화하는 과정이라는 시각에서 접근하여 보안 사고에 의해서 발생하는 사회적 비용과 불편함을 관리하기 위한 정책 대응방안을 탐구한다. 이를 위하여 미국 연방정부 기관에서 발생한 보안사고 통계자료를 분석한다. 보안사고의 유형별 특성에 따라 정보보안을 위한 정책적 노력과 관심이 어디에 우선 집중되어야 하며, 특정 보안 사고에 대해서 어떤 대응 전략이 보다 효과적인가에 대한 정책 논리를 정리하였다. 정보보안은 기술적 수단과 더불어 정책적 대응 전략의 상호보완적 연계를 통해서 불확실성을 관리하는 지속적인 학습과정이라는 점을 재확인한다. Most researches regarding information security underline technological factors in discussing information mis-use and system vulnerability. Technological advance in mitigating security incidents is a critical component. However, legal system, organizational preparedness, managerial framework, and individual awareness for information security should go in parallel with hardware-based measures. This study highlights the society-wide effort for information security as policy responses to manage uncertainty in information society. Historical data on security incidents reported by US. public organizations are reviewed. Incidents are categorized into 3 groups with consideration of frequency. Research findings provide a policy framework for reducing security incidents and managing uncertainty.

A Psychometric Analysis of Risk Perception in Korea

Chung, Ik Jae 서울産業大學校 2002 논문집 Vol.53 No.1

A survey of technological risk perception in Korea was administered in 2001 with a special emphasis an nuclear risks. This paper summarizes the characteristics of risk perception through the analytic lens of psychometric paradigm. A group of experts identified 8 dimensions of risk; voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity. The survey with sample size of 1870 evaluates the perceived level of 25 technological risks including transportation, chemical substance, environmental, industrial, as well as nuclear areas. Research findings confirm that the risk characteristics or dimensions are significant predictors of risk perception. Nuclear risk, for example, is perceived as involuntary, catastrophic, delayed, occasional, controllable, beneficiary, unfamiliar, and necessary. One of research findings from the analysis underlines the need and the importance of nuclear power generation as an environmentally-friendly energy resource in Korea. Effective risk communication can improve the awareness and the understanding of technological risks in modern society, and ultimately facilitate the process of making and implementing policies in the area of risk management and safety regulation.

위험인식의 특성과 의미: 한국인의 기술위험 인지도에 대한 Psychometric 분석

정익재 ( Ik Jae Chung ) 한국안전학회(구 한국산업안전학회) 2014 한국안전학회지 Vol.29 No.1

A survey of risk perception in South Korea was conducted in 2007 to evaluate relative riskiness of typical industrial and technological risks. This article summarizes the characteristics of risk perception using psychometric analyses. The survey with a sample size of 1,194 reviews the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, nuclear power generation, and newly-introduced risks. Six categories of risk identified by a factor analysis show that the level of perceived risk does not correspond to the statistical level. Psychometric analyses including voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity demonstrate that voluntary, familiar and immediate risks are perceived as less risky than involuntary, unfamiliar and delayed ones. Risk communication is critical in reducing the discrepance between objective and subjective level of risk. However, the amount of risk information does not always justify a successful risk communication. A safety policy, risk communication strategy in particular, should take into account diverse dimensions of risk reviewed by psychometric analyses in the study. Social policy toward safety can be improved by integrating policy, human, and social factors as well as technological advances

네트워크 환경에서 과학기술위험에 대한 위험커뮤니케이션 특성과 일반인의 위험인식 및 대응행동의 상호작용 분석 - 후쿠시마 원전사고 중심으로 -

정익재 ( Ik Jae Chung ) 한국정책학회 2018 韓國政策學會報 Vol.27 No.1

본 연구는 네트워크 환경에서 대중매체의 위험커뮤니케이션이 일반인의 위험 인식과 행동에 미치는 영향을 경험적으로 분석하였다. 후쿠시마 원전사고를 다룬 4개 주요 일간지의 인터넷 기사와 댓글, 해당 기사가 트위터와 페이스북을 통해서 전달된 빈도수, 그리고 방사선 전문기관의 진료상담전화 횟수를 비교하여 온라인 위험커뮤니케이션의 특성과 일반인의 반응을 분석하였다. 후쿠시마 사고에 따른 피해의 파급 효과와 사회적 관심의 강도는 다른 재난사고에 비해 훨씬 크지만 대중매체의 보도과정은 일반 사건사고와 유사한 활동주기를 보인다. 신문기사 수와 댓글, 트위터 및 페이스북의 횟수 그리고 상담전화 횟수 사이에 매우 높은 상관관계가 나타났다. 전통적인 매체환경에서 발견할 수 있는 일방향적인 과정과는 달리 온라인 위험커뮤니케이션은 대중매체와 일반인 사이에 양방향의 동태적으로 진행되었다. 신문기사(r=.84)와 페이스북(r=.88)이 일정한 시차를 두고 상담전화와 매우 높은 상관관계를 보였다. 대중매체와 소셜미디어를 통해서 전달, 공유된 위험정보에 의해서 일반인들이 위험을 인지하여 심리적, 정서적 변화 뿐 아니라, 위험에 대응하기 위한 적극적인 행동 변화를 가져왔다. This paper empirically reviews interactive dynamics of mass media, risk perception and public reaction in South Korea in response to Fukushima nuclear disaster. Research data collected from four major online newspapers in the country, which included the number of news articles and talkback replies attached to each article, and frequencies of articles transmitted through social media such as twitter and facebook. Longitudinal data of phone calls received by the call center of a radiological medical service center were also collected. Following the Fukushima accident, mass media and the public showed a strong concern about possible radioactive risk from Japan. Statistical analyses showed significant high correlations among most of major variables examined in this paper. In particular, correlations between 1) news articles and phone calls and 2) facebook uploads and phone calls with two day delay have very high coefficients of .84 and .88, respectively. Research findings underlines dynamic risk communication interacting mass media and the public in the networked environment. Risk information transmitted by online newspaper and social media have a strong influence on not only risk perception, but also behavioral reactions by the public facing a unusual disaster.
