온라인투표의 신뢰 메커니즘에 대한 고찰:온라인투표 보안기술 및 현황 분석을 중심으로

심선영,동상호 한국경영정보학회 2023 Information systems review Vol.25 No.4

In this paper, we investigate how the online voting system can be a trust-based system from a technical perspective. Under four principles of voting, we finely evaluate the existing belief that offline voting is safer and more reliable than online voting based on procedural processes, technical principles. Many studies have suggested the ideas for implementing online voting system, but they have not attempted to strictly examine the technologies of online voting system from the perspective of voting requirements, and usually verification has been insufficient in terms of practical acceptance. Therefore, this study aims to analyze how the technologies are utilized to meet the demanding requirements of voting based on the technologies proven in the field. In addition to general data encryption, online voting requires more technologies for preventing data manipulation and verifying voting results. Moreover, high degree of confidentiality is required because voting data should not be exposed not only to outsiders but also to managers or the system itself. To this end, the security techniques such as Blind Signature, Bit Delegation and Key Division are used. In the case of blockchain-based voting, Mixnet and Zero-Knowledge Proof are required to ensure anonymity. In this study, the current status of the online voting system is analyzed based on the field system that actually serves. This study will enhance our understanding on online voting security technologies and contribute to build a more trust-based voting mechanism.

심선영 大田大學校 大學院 2016 大田大學校 大學院 論文集 Vol.18 No.2

본 연구는 만 1-2세 보육교사와 영아의 애착증진을 위한 어린이집 적응 프로그램을 개발하여, 영아의 안정된 어린이집 적응을 돕고, 보육교사와 영아간의 애착 증진에 목적이 있다. 영아의 안정된 어린이집 적응에 미치는 적응 요소와 애착 형성 요인을 토대로 애착 증진을 위한 어린이집 적응 프로그램을 어린이집과 만남, 선생님·친구들과 만남, 즐거운 어린이집 3단계로 나누어 프로그램을 구성하였다. 영아의 어린이집 적응을 위한 적응 대상을 부모, 보육교사, 어린이집으로 나누어 영아의 애착 증진을 위한 어린이집 적응을 돕고자 프로그램을 개발하였다.

계량 분석 기법을 적용한 경영학 교수법의 효과

심선영 한국경영교육학회 2010 경영교육연구 Vol.63 No.-

In this paper, we apply an analytical teaching approach for Business Administration class and examine the effect of this approach. Between the two classes of 'Production and Operations Management' in the dept. of Business Administration of Seoul Women's Univ., we adopt one class as an experiment group and the other class as the control group. We apply the analytical teaching approach only in the experiment group. The results show that the students in the experiment group experience higher level of commitment, satisfaction, self-efficacy, and behavior intention for the real-world problem solving. Our study evidences the 'analytical teaching approach' as an effective teaching and learning method for quantitative Business Administration courses. 본 연구는 계량분석기법이라는 교수법을 이론 교육에 접목함으로써 경영학 교수의 효과를 높이는 것에 대해 고찰해 본다. 서울여자대학교의 생산관리 수업을 통해 2개의 분반 중 하나의 분반에는 계량분석기법을 적용하고 나머지 분반에는 적용하지 않았다. 연구결과 이 기법이 적용된 분반의 경우 학습자의 몰입도나 만족감 그리고 자기효능감이 훨씬 높았으며 또한 이것은 향후 학습내용을 실전의 문제해결에 적용하려는 의지로 이어짐을 알 수 있었다. 따라서 경영학의 일부 계량적 접근을 요하는 교과목들은 이론 강의뿐 아니라 계량분석실습을 적절히 조화함으로써 향후 학습자의 문제 해결 능력을 함양하는 효과적인 교수법이 될 수 있음을 실증한다.

Pre and Post Evaluations on IT Platform Migration to Open Systems

심선영,김은진 한국데이터전략학회 2008 Journal of information technology applications & m Vol.15 No.3

IT platform migration to open systems (IPMO) bears a great deal of risk over all the associated processes, in terms of a major IT investment. Hence it requires empirical data and references for decision making. Although there have been a number of published papers encouraging or discouraging IPMO, the studies that deliver useful empirical evidence for IPMO decisions are rare. The obvious first step to resolve this problem would be to gain lessons from the organizations who experienced IPMO. Based on the Delphi study, we examine both the pre and post evaluations on IPMO benefits and risks and analyze the underlying reasons of different evaluations from different stages. Our results identify the most important factor the organizations should seriously consider, and which factor is easy to neglect at the ex-ante appraisal stage.

기업 간 유대강도가 지식획득과 지식통합 및 혁신성과에 미치는 영향에 대한 연구:산업단지 내 중소기업을 중심으로

심선영 한국정보시스템학회 2019 情報시스템硏究 Vol.28 No.2

Purpose The purpose of this study is to examine the impact of tie strength in the network of industrial clustering on the knowledge acquisition, integration and innovation performance of small and medium sized enterprises. We test the positive relationship of weak tie and knowledge acquisition, strong tie and knowledge integration, and the interaction effect of two tie strengths on both processes of knowledge acquisition and integration. By identifying these relationships, we can better understand how to manage the attributes of social networks in terms of tie strength in order to improve the performance of innovation for the small and medium sized enterprises. Design/methodology/approach We collect 200 survey data from 2 industrial cluster respectively: Pankyo and Guroo. In Pankyo, the proportion of IT industry is the highest (35%) while the proportion of manufacturing is highest (35%) in Guroo. Pooling the data from two industrial cluster, we check the reliability and validity of our research model and test the hypotheses. Findings First, we find the positive relationship of weak tie and knowledge acquisition from both industrial clustering. Weak tie is composed of heterogeneous organizations with various background and expertise. The communication and information sharing of organizations in the weak tie network helps the idea generation for organization’s innovation, which is the knowledge acquisition process. Second, the relationship of strong tie and knowledge integration is insignificant. Typically the strong tie from long-lasting partnership is expected to be beneficial in the action stage of innovation, which is the knowledge integration process. However it is not identified in our industry cluster. Finally, the interaction effect of weak and strong tie is identified to be effective on both knowledge acquisition and integration processes.

This study investigates the impact factors of mobile voting adoption for the efficiency of apartment house management of Seoul city. It examines the positively influencing factors on the mobile voting introduction in the operational, technological and economic perspectives and analyzes the moderating factors as well in both individual and social parts. The results show that the higher consciousness on the participation, voting security and the voting cost leads to the more positive attitude on the mobile voting. As the moderating factors, the personal factor of the capability of smartphone utilization and the social factor of supports of the policy are significantly identified. Mobile voting delivers the advantages of high participation rate and cost saving. By identifying the positive impact factors on the mobile voting adoption, this study discusses the managerial and policy implications for the smart direct democracy based on the mobile voting. 이 연구는 서울시 공동주택관리 효율화를 위한 모바일 투표 도입의 영향요인을 고찰한다. 모바일 투표 도입의 긍정적 영향요인을 운영적·기술적·경제적 측면에서 살펴보고, 개인·사회적 요인의 조절 효과도 분석하였다. 연구 결과, 개인의 참여의식이 높고, 투표보안을 기술적으로 인지하고 있으며 투표비용에 관한 경제적 관심이 클수록 모바일 투표에 긍정적 태도가 형성되었다. 조절 효과는 개인적 요인(스마트폰 활용 능력)과 사회적 요인(정책적 지원) 모두 모바일 투표를 대하는 태도가 모바일 투표 수용 의지로 이어지는 데 긍정적 역할을 하는 것으로 밝혀졌다. 이 연구는 높은 투표율과 비용 경제성을 제공하는 모바일 투표의 긍정적 영향요인을 분석해 모바일 투표에 기반을 둔 스마트 직접 민주주의 실현의 관리적·정책적 함의를 도출하였다.

Does Brokerage Commission Determine Market Share of an Online Brokerage?: An Empirical Investigation of Online Brokerage Services

심선영 한국전략경영학회 2009 전략경영연구 Vol.12 No.2

The effectiveness of online medium to brokerage service not only delivers business opportunities but also intensifies competition between online brokerages. Although low price and high quality have received great attention as means of significant customer attraction strategies, there is a paucity of empirical study that investigates these two factors together in the online brokerage area. Hence we utilize price and quality as the lens to examine the determinants of online brokerage’s market share and empirically investigate the effects using firm level panel data spanning 8 years. Our study gives an important warning on the online brokerages’ reckless adoption of commission discount strategy. The quality of the trading system shows the central and dominant contribution to market share. The growing importance of interest revenue in the online brokerage business is also confirmed by our study. Our study delivers valuable implications for online brokerages as well as various e-commerce firms.
