A Novel Forged Image Detection Method Using the Characteristics of Interpolation

Development of digital image‐editing programs has enabled us to be widely exposed to forged digital images surrounding us. Such forged images have been dispersed through the Internet, newspaper articles, and magazines, and in particular, the information contained in these unverified images happened to be regarded as true. As a result, the forged images provided wrong information for individuals and society, thus sometimes creating social issues. In order to solve such problems, this study was aimed to suggest the methods of identifying the veracity of forged images. In this way, it suggested re‐interpolation algorithm. Namely, the study re‐interpolated in identical arbitrary values both the interpolated and un‐interpolated regions based on the interpolation used a lot in forged, confirmed discrete fourier transform (DFT) characteristics of these two regions, and embodied a detection map for the final forged images, using the subtraction value between two regions in DFT characteristics.     

Pathways into Terrorism: Understanding Entry into and Support for Terrorism in Asia

ABSTRACT

How do individuals join Islamist extremist groups? Why do individuals support such groups? What factors contribute to a decision to join? What are the pathways into Islamist extremist groups? Drawing on examples from Pakistan, Bangladesh, Indonesia and the Philippines, the articles in this special issue address these critically important questions drawing on original fieldwork, new datasets and large scale national survey research. These articles explore the experiences and perceptions of men and women, South and Southeast Asians, living in majority Muslim and non-Muslim nations. Collectively, they illustrate the importance of social bonds&kinship ties, friendship, teacher-student ties and online relationships in creating a powerful sense of community that fosters a sense of belonging and eventual commitment. The goal of this special issue is to highlight the contributions that Asian cases can make to the often Middle Eastern and European-centric discourses on radicalization, joining and support for militancy.     

Why They Join: Pathways into Indonesian Jihadist Organizations

ABSTRACT

Why do Indonesian Muslims join Islamist extremist groups? This article explores four pathways to entry into Indonesian militant groups: study sessions, local conflict, kinship, and schools. It argues that within all four of these pathways, social bonds and relationships are the common thread in encouraging entry as well as in fostering commitment. Specifically, these relationships contribute to the formation and eventual consolidation of one’s identity as a member of the jihadi group through regular participation in activities, attending meetings, narrowing the circle of friends to those within the group, and participating in increasingly risky and possibly violent activities together. Drawing on original fieldwork including 49 interviews with current and former members of Jemaah Islamiyah, Mujahidin KOMPAK, Darul Islam, Mujahidin Tanah Runtuh, Indonesia’s pro-ISIS network, and other jihadist groups as well as 57 depositions and court documents, this article explores the development and evolution of these pathways and how relational ties play a role in each.     

The reasons for choosing a career in policing among South Korean police cadets

Despite the importance of understanding the reasons for choosing the police as an occupation for developing effective recruiting strategies, there is a surprising lack of research about what motivates people to choose careers in policing in South Korea. Employing the sample of 410 Korean police cadets, the study found that a financial factor — “steady salary” and “job security” — was the most important factor affecting the decisions of police cadets to join the police. Regression analyses indicated that gender and social-economic status had significant effects on cadets' motivation of joining the police. In the conclusion, policy implications for developing an effective recruitment strategy are discussed.     

战略合作伙伴关系下的中韩军事关系

中韩两国领导人宣布两国建立战略合作伙伴关系,使两国再次关注最薄弱的军事领域合作.根据合作的深度,军事关系一般可分为军事交流、军事合作、军事同盟三个层次,目前中韩军事关系十分接近第一层次.由于韩美同盟、中朝关系以及中韩军队自身特点等原因,中韩军事关系不可能达到第三层次,但有可能达到第二层次.若双方都有将两国军事关系在目前基础上再向前发展一步的想法,那么两国应该从现在起就积极努力,因为这是建立相互信任的捷径.通过两国军队自身努力和相关国家的理解,中韩军事关系这种水平的发展还是可以实现的,而且两国军事关系的深化也将有助于东北亚地区的和平稳定.     

An accuracy assessment of forensic computerized facial reconstruction employing cone-beam computed tomography from live subjects

The utilization of 3D computerized systems has allowed more effective procedures for forensic facial reconstruction. Three 3D computerized facial reconstructions were produced using skull models from live adult Korean subjects to assess facial morphology prediction accuracy. The 3D skeletal and facial data were recorded from the subjects in an upright position using a cone-beam CT scanner. Shell-to-shell deviation maps were created using 3D surface comparison software, and the deviation errors between the reconstructed and target faces were measured. Results showed that 54%, 65%, and 77% of the three facial reconstruction surfaces had <2.5 mm of error when compared to the relevant target face. The average error for each reconstruction was -0.46 mm (SD = 2.81) for A, -0.31 mm (SD = 2.40) for B, and -0.49 mm (SD = 2.16) for C. The facial features of the reconstructions demonstrated good levels of accuracy compared to the target faces.     

Efficient height measurement method of surveillance camera image

As surveillance cameras are increasingly installed, their films are often submitted as evidence of crime, but very scant detailed information such as features and clothes is obtained due to the limited camera performance. Height, however, is relatively not significantly influenced by the camera performance. This paper studied the height measurement method using images from a CCTV. The information on the height was obtained via photogrammetry, including the reference points in the photographed area and the calculation of the relationship between a 3D space and a 2D image through linear and nonlinear calibration. Using this correlation, this paper suggested the height measurement method, which projects a 3D virtual ruler onto the image. This method has been proven to offer more stable values within the range of data convergence than those of other existing methods.     

Paternity probability when a relative of the father is an alleged father

When scientists use DNA evidence in court, coancestry effects such as population structure and relatedness are usually ignored. In paternity cases, only if a particular man has the child's paternal allele at a certain locus, can he not be excluded in the paternity dispute. However, it is certainly true that close relatives will be far more likely to have the child's paternal allele than will random members of the reference population. In particular, the probability that the true father's brother has the paternal allele is very much greater than that for any other relationship. In this paper, the authors describe a method for inference in a case where the true father may be a relative of the alleged father. This paper also reports that most current methods overstate the probability that the alleged father is the father.     

Cold War brotherhood contested: KATUSAs,slicky boys,American G.I.s,and the Status of Forces Agreement in post-armistice South Korea, 1954–1966

ABSTRACT

As the largest contingent of Americans in postwar South Korea, the G.I. best represented the United States’ Cold War objectives. Their deployment was an emblem of hard power containment, but the G.I. also embodied soft power integration, and through both, G.I.s helped to promote Pax Americana. This article focuses on the militarized masculinity of these ambassadors of America and their people-to-people diplomacy in South Korea between 1954 and 1966. These American G.I.s constructed their militarized masculinity vis-à-vis the Korean male Other, their “lesser” counterparts – the hapless houseboy, the inferior partner soldier, and the menacing slicky boy. At the same time, this liberal imperialism did not go uncontested. Violent imaginaries of the American G.I. from the borderlands were used by Koreans to demand a new bilateral framework – the Status of Forces Agreement in 1966 – to replace the outmoded wartime extraterritorial jurisdiction wielded by the American military after cessation of hostilities on the Korean peninsula in 1953. The militarized masculinity practiced in everyday encounters, thus, became the basis of a critique of American liberal imperialism in one of the United States closest Cold War “brother” nations.
