Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.     

Study on the standard components of digital forensics laboratory

Recently, digital forensics has become increasingly important as it is used by investigation agencies, corporate, and private sector. To supplement the limitations of evidence capacity and be recognized in court, it is essential to establish an environment that ensures the integrity of the entire process ranging from collecting and analyzing to submitting digital evidence to court. In this study, common elements were extracted by comparing and analyzing ISO/IEC 17025, 27001 standards and Interpol and Council of Europe (CoE) guidelines to derive the necessary components for building a digital forensic laboratory. Subsequently, based on 21 digital forensic experts in the field, Delphi survey and verifications were conducted in three rounds. As a result, 40 components from seven areas were derived. The research results are based on the establishment, operation, management, and authentication of a digital forensics laboratory suitable for the domestic environment, with added credibility through collection of the opinions of 21 experts in the field of digital forensics in Korea. This study can be referred to in establishing digital forensic laboratories in national, public, and private digital forensic organizations as well as for employing as competency measurement criteria in courts to evaluate the reliability of the analysis results.     

NORTH KOREA’S PERSPECTIVES IN ITS ARGUMENT FOR A PEACE TREATY

In recent years, North Korea’s military provocations have been making the headlines. Beyond its harsh actions and remarks, North Korea persistently mentions ‘peace’ through a demand for a ‘peace treaty’. This may sound paradoxical. However, the origin of the North Korean argument for a peace treaty dates back to the Korean War (1950–53). Since then, North Korea has continued to raise the issue of a peace treaty in a consistent manner and the arguments have displayed similar logic and terminology throughout. It is this consistency and similarity that this article examines: through reviewing North Korea’s original texts, this article attempts to undercover North Korea's perspectives reflected in its argument for a peace treaty.     

Eastern Mediterranean Gas Discoveries: Local and Global Impact

The ongoing discoveries of natural-gas reserves in the eastern Mediterranean region significantly affect international relations. Since their viability has been increasingly confirmed, they have attracted public attention in the international energy market. Focusing on current gas production and trading in the Middle East, this paper studies the anticipated impact of gas production in the sea on geopolitical relations in the Middle East and investigates how these results may change the geoeconomic strategies of global energy-market players as well as nearby countries. In addition, our analyses provide comprehensive insights into the evolution of gas discoveries in the Eastern Mediterranean.     

South Korean views on Japan's constitutional reform under the Abe government

In this Special Section, this article reviews South Korean views on Japan's ‘peace’ Constitution and the Abe government's attempts at constitutional reform. It identifies three different understandings among South Korean academics on why Japan is escalating attempts to revise the Constitution under the Abe government. An in-depth analysis demonstrates that all three perspectives pay specific attention to Japan's constitutional reform in relation to security policy changes. However, they differ in assessing the impact of Japan's constitutional reform on South Korea as well as how South Korea should deal with such a change. A minority opinion considers Japan's ‘remilitarisation’ through constitutional revision as conducive to South Korean security interests by increasing deterrence against North Korea, whereas the dominant opinion is that any attempt to revise the Constitution could be in and of itself a potential threat to South Korea's security due to a lack of trust attributed to unresolved historical conflicts between Korea and Japan. However, all three approaches pay hardly any attention to the positive role of Japan's peace Constitution while Japan's peace Constitution might provide a regional peace model in Northeast Asia.     

Internalizing Symptoms: Effects of a Preventive Intervention on Developmental Pathways from Early Adolescence to Young Adulthood

This study examined the mediated and moderated effects of a universal family-focused preventive intervention, delivered during young adolescence, on internalizing symptoms assessed in young adulthood. Sixth grade students (N=446; 52% female; 98% White) and their families from 22 rural Midwestern school districts were randomly assigned to the experimental conditions in 1993. Self-report questionnaires were administered at seven time points (pre-test to young adulthood-age 21) to those receiving the Iowa Strengthening Families Program (ISFP) and to the control group. Results showed that growth factors of adolescent internalizing symptoms (grades 6-12) were predicted by ISFP condition and risk status (defined as early substance initiation). Moderation of the condition effect by risk status was found, with higher-risk adolescents benefitting more from the ISFP. Results also supported the hypothesis that the ISFP's effect on internalizing symptoms in young adulthood was mediated through growth factors of adolescents' internalizing symptoms; risk moderation, however, was only marginally significant in young adulthood. The relative reduction rate on clinical or subclinical levels of young adult internalizing symptoms was 28%, indicating that for every 100 young adults displaying clinical or subclinical levels of internalizing symptoms from school districts not offering an intervention, there could be as few as 72 displaying those levels of symptoms in school districts that offered middle school prevention programming. These findings highlight how the positive effects of family-focused universal interventions can extend to non-targeted outcomes and the related potential public-health impact of scaling up these interventions.     

The Impact of Prenatal Exposure to Power Plant Emissions on Birth Weight: Evidence from a Pennsylvania Power Plant Located Upwind of New Jersey

To examine the infant health impact of prenatal exposure to power plant emissions, we draw scientific evidence on the impacted region downwind of a large polluter, a coal‐fired power plant located on the border of two states and proven to be the sole contributor to the violation of air quality standards of the impacted region. Our results show that among all live singleton births that occurred during 1990 through 2006, those born to mothers living as far as 20 to 30 miles away downwind from the power plant (which is also an affluent region) during pregnancy are at greater risks of low birth weight (LBW) and very low birth weight (VLBW): the likelihoods of LBW and VLBW could increase approximately by 6.50 and 17.12 percent, respectively. In light of the continual efforts of The U.S. Environmental Protection Agency in reducing cross‐state air pollution caused by transboundary power plant emissions, our study is aimed at broadening the scope of cross‐border pollution impact analysis by taking into account adverse infant health effects of upwind polluters, which can impose disproportionate burdens of health risks on downwind states due to air pollutants transported by wind.     

Postwar Japan-China Relations: A Consideration from the Perspective of Reconciliation

This article attempts to take a new look at postwar Japan-China relations from the perspective of reconciliation. In contrast to the Murayama and Koizumi statements, one key phrase characterized both the August 14, 2015 Abe Statement and the report of the 21st Century Advisory Panel, which had been submitted earlier to the government: that key phrase is “postwar reconciliation.”     

Organizing K-Pop: Emergence and Market Making of Large Korean Entertainment Houses, 1980–2010

This paper studies the connection between the emergence and market making activities of the large Korean entertainment houses and the global level success of “K-pop,” an increasingly popular type of Korean popular music. We review a set of conventional explanations, respectively pointing to cultural factors, government support, and technological development as core factors that led to the global success of K-pop. We find all three explanations unsatisfactory and, alternatively, building on studies of market intermediaries, argue that the roles of three large entertainment houses—SM Entertainment, YG Entertainment, and JYP Entertainment—have been the most crucial in the development and success of K-pop. Through combining data from Korean music charts, newspaper articles, and revenue data, we trace the increasingly systematic musical production strategies of the entertainment houses and the macro-consequences of their organizational activities.
