기존의 특징점 추출 알고리즘들은 입력 지문의 전처리, 이미지의 이진화, 세선화, 특징점 추출 등의 여러 처리 단계를 거쳐 이루어지므로 잡음등과 같은 외부적 요인과 여러 처리단계엣 발생하는 내부적 요인 등으로 왜곡 현상을 피하기 어렵고 전체 인증 시간이 길어 지는 등 성능 저해 요인이 많다. 본 논문에서는 복잡한 처리 과정을 거치지 않고 입려영상에서 집적 융선의 흐름을 추적하여 특징점들을 추출하고 매칭을 수행함으로써 이미지의 왜곡에서 오는 오류를 줄이고 처리 시간을 단축하여 기존의 시스템보다 빠른 시간에 지문을 인식하는 시스템을 설계 및 구현한다.

본 연구에서는 기존에 다양한 형태로 이루어져 온 사이버 쇼핑몰의 신뢰와 관련된 연구에 대한 문헌고찰을 통해 신뢰 형성의 선행요인들을 도출해 낸 후, 이러한 선행요인들이 사이버 쇼핑몰의 신뢰에 미치는 영향을 체계적으로 규명하고, 그 영향요인이 종합쇼핑몰과 전문쇼핑몰로 구분되는 쇼핑몰 유형에 따라 어떠한 차이를 보이는지 분석해 보고자 하였다. 신뢰 형성에 영향을 미치는 선행변수로는 거래 안전성, 지각된 평판, 지각된 규모, 상호작용성, 신뢰성향을 설정하고, 이들 요인들이 사이버 쇼핑몰의 신뢰에 미치는 인과관계를 검증 한 결과, 거래 안전성, 지각된 평판, 상호작용성, 신뢰성향이 유의한 영향을 미치는 것으로 나타났다. 또한 이러한 인과관계자 종합쇼핑몰 및 전문쇼핑몰에 따라 어떻게 차이를 보이는지 분석해 본 결과, 거래 안전성과 지각된 평판 요인에서 통계적으로 유의한 차이자 발생하였다. 본 연구의 결과를 통해 사이버 쇼핑몰에서 점차 중요성이 더해지고 있는 신뢰 형성의 영향요인을 파악하고, 이를 쇼핑몰 유형별로 비교분석을 해 봄으로써 쇼핑몰에 대한 신뢰 형성의 원천과 그 영향력에 대한 체계적인 접근 방법을 제공함으로써 사이버 쇼핑몰 운영자에게 효과적인 관리전략 수립을 위한 시사점을 제공하고자 하였다.

This study aims to suggest key strategy for successful establishment of LIS (Land Information System). Survey questionnaires on casual and outcome factors for LIS establishment are distributed to the LIS users and developers. Analysis results show that user participation has statistically significant, positive effect on business efficiency, user satisfaction, data sharing and services. Government support and developer technical skill are appeared to be the two important factors for improving the business efficiency and user satisfaction of LIS. Based on such results, this study suggests different strategies for successful development and implementation of LIS, including the definition of users' role and their proactive participation, visionary guide and support by government, cooperative relationship based government support and user participation, sufficient technology for land informatization. This study contributes to systematic organization of situational factors of South Korea's LIS towards its achievements. The results of this study could also be utilized for strengthening global competitiveness of the domestic geospatial information firms, in particular in supporting the development of land information projects in developing countries.

To analyze the national competitiveness of Korea leads to the conclusion that global high-tech enterprises have been playing leading and pulling roles in making Korea in line with advanced countries even though the country is lacking in various natural resources. The characteristics of these companies above are as follows; Firstly, these enterprises continue to accumulate core technologies and know-how with highly competent human resources and well-organized management. Secondly, they are well structured and equipped with information technology infrastructures which are, for example, ERP, SCM, CRM, and PLM. Among them PLM is considered to be the principal core information technology infra in manufacturing industry. The urgent task of manufacturing industry recently is to develop new products to accept various needs of consumers, and to launch the products in time to market, which requires the manufactures to be equipped with product development infra and system to upgrade product fulfillment and mass production system in a short period. The introduction of PLM System is a solution of core strategy as a manufacturer for collaboration, global development, reengineering of manufacturing system, the innovation and efficiency of manufacturing process, and product quality improvement. The purpose of this study is to analyze the success factors of introducing PLM System and its practicing effectiveness. And the results of empirical study are as follows; (1) Technical success factors positively impact system quality and user satisfaction, (2) Organizational success factors positively impact system quality, but does not impact user satisfaction, (3) Environmental success factors positively impact system quality and user satisfaction, (4) System quality positively impacts user satisfaction, (5) User satisfaction positively impacts the effectiveness of implementing PLM systems, but system quality does not impact it.

This study was attempted to determine the satisfaction of nursing students' online classes in the situation of coronavirus infection (COVID-19) and to identify factors affect it. This study conducted a survey on nursing students 220 in Daegu-Gyeongbuk area for a month in April 2021. The collected data were subjected to t-test, ANOVA, correlation, and multiple regression analysis. As a result of analyzing the factors affecting the online class satisfaction of nursing students, the learner factor (β=.29, p<.001) and the system factor (β=.51, p<.001) had a statistically significant effect, the variable with the greatest relative influence was the system factor. As online classes are expected to expand even after the end of COVID-19, for a change to education that can increase the satisfaction of learners, through the development of an online operating system suitable for learning and establishing a foundation for learners to learn independently A paradigm shift in nursing education is necessary.

This research explores the factors affecting infusion of public administrative information systems(IS) and analyzes its impact on work performance. For this purpose, the factors affecting the infusion of IS are classified into voluntary and involuntary motivations based on the self-determination theory that explains individual motivations. As factors for voluntary motivation, performance expectancy, personal innovativeness, and organizational citizenship behavior are proposed, while government influence, competitor influence, and the top-level management influence are proposed as factors for involuntary motivation. The analysis shows the voluntary motivation factors-performance expectancy, personal innovativeness, and organizational citizenship behavior-do affect infusion of IS, whereas the involuntary motivation factors-government influence, competitor influence, and the top-level management influence-have no statistically significant impact on the infusion of IS. The relationship between infusion of IS and work performance is found significant. While individuals are unable to decide on the adoption of IS in an involuntary environment such as in the case of using the public administrative IS, the results show that the factors related to individual autonomy have an important role in extended, active usage of IS beyond the mandatory level.
