범죄 빅데이터에 대한 개인정보 제공과 프라이버시 염려 : 정부신뢰의 매개・조절효과를 중심으로
박혜석 한국정책학회 2020 韓國政策學會報 Vol.29 No.3
In information society, crime has become diversified and advanced. As it becomes difficult to respond effectively with police activities alone, a new innovative technology called big data is being sought as an alternative. Of these public polices, Crime Prevention System utilizing big data needs to collect personal information through agreement to provision. However, in dealing with the personal information, privacy concern has been a serious issue as a right for a long time. This article suggests that trust on government could be a critical variable in that government is the subject to collect personal information and that how to deal with the information and security might affect the support and participation in the public policy. As the solution of the trade-off between privacy and personal information, this article found the effect of trust on government in mediating and/or moderating the relation of privacy concern and provision of personal information especially for Crime Prevention System using big-data assuming that trust on government might affect the citizen’s participation positively for public security policy. 오늘날과 같은 정보화 사회에서 범죄는 보다 다양화․첨단화되면서 경찰 활동만으로는 신속하고 정확하게, 효과적으로 대응하기 어려워졌고, 다양한 정보를 통해 과학적이고 합리적인 대응이 모색되어지고 있다. 이러한 가운데 최근 빅데이터(Big Data)라는 새로운 기술 혁신이 대두되면서 이를 이용한 각종 정부 정책대안들이 모색되고 있고, 동의를 통해 사람들의 개인정보를 수집하면서 활발히 활용되고 있다. 그러나, 개인정보의 수집과 관련하여서는 프라이버시 침해의 문제를 고려하지 않을 수 없고, 수집 주체가 되는 정부에 대한 신뢰는 공공정책에 대한 지지 및 참여에 영향을 미칠 수 있다는 점에서 정부신뢰는 중요한 변수가 될 수 있다. 본 연구에서는 정부신뢰가 시민들의 참여에 긍정적인 영향을 미칠 것이라는 가정을 하면서, 정부신뢰의 효과가 시민참여로서의 개인정보제공에 미치는 영향을 매개변인으로서의 효과와 조절변인으로서의 효과를 살펴보았다.

본 연구는 장애인연금 제도 도입 이후 장애인들의 생활수준 변화를 이중차이모형을 통해 분석하여 정책의 효과성을 평가하고자 한다. 소득 지표를 통한 기존의 복지측정 방식은 삶의 수준을 간접적으로만 반영한다는 비판적 시각에서 장애인들의 소비지출 변화를 측정함으로써 장애인연금이 생활수준에 미친 영향을 보다 직접적으로 살펴보았다. 중증장애인가구로 대상을 한정하여 분석한 결과, 정책효과는 여가비와 교육비에서만 나타났고 총생활비와 여가비, 장애추가비에서 장애인연금 비수급집단과 수급집단간의 격차가 여전히 존재하였으며, 수급집단에서 각 지출의 유의미한 증가가 나타나지 않았다. 결국 전반적으로 현행 장애인연금제도는 기존의 집단간 차이를 줄일 수 있을 만큼의 효과를 나타내지는 못했다는 점에서, 장애인연금의 정책효과가 나타나기 위해서는 현재보다 급여수준이 인상될 필요가 있다. 또한 장기적으로 중증장애인들의 실질적 생활수준 향상이라는 정책목표를 달성하기 위해서는 장애인들을 위한 교육 및 취업정책, 연령과 가구원수를 고려한 소득보장 및 사회보장제도의 확대가 요구된다. The primary purpose of this study is to evaluate the effectiveness of Disability Pension in 2010 for the severe disabled in Korea. This pension policy intends to ensure the standard of living for the severe disabled by offering the income supplement. However, income supplement in itself means merely the equality of opportunity, not the one of result. Therefore, this study accept the concept of Ringen, that is consumption or expenditure approach, and take the consumption/expenditure as dependent variables. The method for analysis is Difference-in-Difference model; DID in the groups divided into experimental and comparative group means the effect of policy. According to the results, the policy effect appears in leisure and educational cost, the difference between the groups still exists, and the change in consumption/expenditure is not significant. Thus, considering the result of analysis, it is recommended that the expansion of pension benefits, educational, job-concerned policy, and more expanded income maintenance programs be needed.

The purpose of this study was to compare adult learning strategy of adults, using the data of the 2012 OECD Adult Learning Survey used in the Program for International Assessment of Adult Competencies(PIAAC). Korean adults were the lowest in the learning strategies among 23 countries. Learning strategies scores showed differences according to age, gender, years of learning, and adult learning participation. A positive relationship of learning strategies with competencies were found after adjusting to age, gender, years of education and adult learning participation. 본 연구에서는 OECD 국제성인역량조사(PIAAC)의 데이터를 활용하여 한국 성인의 학습전략 수준을 다른 나라와 비교하고, 학습전략과 평생학습, 성인 역량과의 관계를 살펴보았다. 한국 성인의 학습전략 수준은 23개 국가 가운데 가장 낮았다. 젊은 층일수록, 여성보다는 남성이, 교육수준이 높을수록 학습전략 점수가 높았으며, 평생학습에 참여하는 사람이 참여하지 않는 사람보다 학습전략 점수가 높게 나타났다. 언어능력과 수리력으로 측정한 성인의 역량과 학습전략은 학력, 연령, 평생학습참여 여부를 통제한 후에도 유의미한 관계가 있었다. 성인 학습의 질 제고를 위하여 학습전략의 중요성을 고려할 필요성을 정책적 시사점으로 제시했다.

Previous studies on the application of tomosynthesis to breast imaging have demonstrated the potential of digital breast tomosynthesis (DBT). DBT can improve the specificity of digital mammography (DM) through improved marginal visibility of lesions and early breast cancer detection for women with dense breasts. To investigate possible improvements in the accuracy of lesion detection with DBT systems as compared to DM, we conducted a quantitative evaluation by using simulated lesions embedded in a breast phantom. A prototype DBT and dedicated DM system were used in this study. For the DBT system, the average glandular dose (AGD) was calculated using a formalism that was a simple extension of mammography dosimetry. The DBT and the DM images were acquired with average glandular doses (AGDs) ranging from 1 to 4 mGy. To analyze the results objectively, we calculated metrics for in-plane lesion visibility in the form of the contrast-to-noise ratio for the in-focus plane from the DBT reconstruction image and from the craniocaudal (CC)image from the DM system. The imaging performance of DBT was quantitatively compared with that of DM in terms of the figure of merit. Although the DM showed better results in terms of the contrast-to-noise ratio (CNR) of the mass due to the reduced overlapping of tissue and lesion, an increase in breast thickness of over 3 cm increased the CNR of the mass with the DBT system. For microcalcification detection, the DBT system showed significantly higher CNR than the DM system and gave better predictions of the microcalcification size. We compared the performances of the DM and the DBT systems for various AGDs and breast thicknesses. In conclusion, the results indicate that the DBT systems can play an important role in the detection of masses or microcalcifications without severe compression.

There have been many efforts to advance the technology of X-ray digital mammography in order to enhance the early detection of breast pathology. The purpose of this study was to evaluate image quality and the radiation dose after magnifying X-ray digital mammography using the Geant4 Application for Tomographic Emission (GATE). In this study, we simulated a Monte Carlo model of an X-ray digital mammographic system, and we present a technique for magnification and discuss how it affects the image quality. The simulated X-ray digital mammographic system with GATE consists of an X-ray source, a compression paddle, a supporting plate, and an imaging plate (IP) of computed radiography (CR). The degree of magnification ranged from 1.0 to 2.0. We designed a semi-cylindrical phantom with a thickness of 45-mm and a radius of 50-mm in order to evaluate the image quality after magnification. The phantom was made of poly methyl methacrylate (PMMA) and contained four spherical specks with diameters of 750, 500, 250, and 100-µm to simulate microcalcifications. The simulation studies were performed with an X-ray energy spectrum calculated using the spectrum processor SRS-78. A combination of a molybdenum anode and a molybdenum filter (Mo/Mo) was used for the mammographic X-ray tubes. The effects of the degree of magnification were investigated in terms of both the contrast-to-noise ratio (CNR) and the average glandular dose (AGD). The results show that the CNR increased as the degree of magnification increased and decreased as breast glandularity increased. The AGD showed only a minor increase with magnification. Based on the results, magnification of mammographic images can be used to obtain high image quality with an increased CNR. Our X-ray digital mammographic system model with GATE may be used as a basis for future studies on X-ray imaging characteristics.
