This is the third article of a three part series introducing historical museums in Japan and their role in public education on issues of war, peace, war crimes and reconciliation. The first article is Takashi Yoshida's “Revising the Past, Complicating the Future: The Yushukan War Museum in Modern Japanese History.” The second article is Rumiko Nishino's “The Women's Active Museum on War and Peace.”

The issue of forced labor during the Asia-Pacific War (1931-1945) remains a stone of contention in Japanese-Korean relations. While the governments of the two countries seem to put the issue aside in order to improve economic and military ties, civil society in both countries remains suspicious. The Asia Pacific Journal: Japan Focus here introduces the positions of representatives of two civil society organizations from South Korea and Japan, respectively, explaining why the government approach to address historical injustices remains unsatisfactory.

Discrimination experiences are a salient contributor to the health disparities facing Latina/x/o youth. The biopsychosocial model of minority health posits that discrimination influences health through wear and tear on the biological stress responses, including the hypothalamic-pituitary-adrenal (HPA) axis, which is a primary stress response system in the body. Emerging evidence suggests that discrimination alters the secretion of cortisol, the end product of the HPA axis, yet, whether the daily processes between discrimination and diurnal cortisol response influence mental and sleep health remains unanswered. This study integrated daily diary and post-diary survey data to examine whether daily diurnal cortisol responses to discrimination influence adolescents’ mental (depressive symptoms, anxiety) and sleep (sleep quality, duration) health in a sample of Mexican-origin youth (N = 282; Mage = 17.10; 55% female). Results showed that adolescents who experienced more discrimination across the four-day diary period exhibited steeper diurnal cortisol slopes and lower evening cortisol; however, such physiological responses tended to be associated with poorer adolescents’ mental and sleep health. The current study underscores the potential adaptation cost associated with short-term cortisol adaptation in the face of discrimination.

South Korea has recently experienced a queer historical turn. Contemporary Korean queer artists have been increasingly reanimating queer pasts in order to imagine queerness as a sense of togetherness. siren eun young jung’s Yeosung Gukgeuk Project (2008–present), one of the most celebrated works of queer art in South Korea, is a queer rendition of yeosung gukgeuk, a genre of all-female Korean opera of the 1950s and 1960s.

We compared South Koreans with Australians in order to characterize cultural differences in attitudes and choices regarding risk, at both the individual and group levels. Our results showed that Australians, when assessed individually, consistently self-reported higher preference for risk than South Koreans, regardless of gender. The data revealed that South Koreans, regardless of gender composition, were willing to take greater risks when making decisions in group decision-making situations than when they were alone. This is a different pattern from that seen in the Australian sample, in which a risky shift was noted only among males. This difference was attributed to the influence of various cultural orientations (independent vs. interdependent relationship styles). This study also provides a discussion of the implications of these results in terms of cultural differences in attitudes and decisions regarding risk.

Scholars have generally underestimated the level of Roman involvement in Africa in the period between the annexation of Carthage in 146 b.c. and Caesar's victory at Thapsus in 46 b.c., and the land in Africa which the Romans annexed has been conventionally called public land (ager publicus). This paper analyses the surviving text of the African provisions of the epigraphic lex agraria of 111 b.c. and notes that the term ager publicus is not attested in the provincial section of the law. The land in Africa appears simply as ager in Africa and the term ager publicus is confined exclusively to Italy in the law of 111. However, Cicero's references to Rullus’ agrarian proposal in 64/3 b.c. in the De lege agraria suggest that the term ager publicus was used to qualify land existing outside Italy in Rullus’ proposal. This paper argues that the concept of ager publicus as opposed to private land developed in Africa between 111 and 63 b.c., and that this was linked to privatization of ager in Africa in this period. The results of this study suggest a high degree of Roman exploitation of African land prior to the Caesarean and Augustan colonies in the 40s b.c.

The extensive traces of Roman centuriation and its associated farms identified from aerial photographs near Lucera, ancient Luceria, in the plain of northern Apulia, have generally been attributed to the Gracchan agrarian reforms of the 130s/120s BC. However, the dating of these land divisions, on the basis of the excavation of the farms and centuriation roads by John Bradford and Barri Jones in 1949–50 and 1962–3, is of questionable reliability, and their work at Luceria was never properly published. This study reanalyses the scattered records and dating evidence from the excavation of seven farms of Bradford and Jones and three other sites surveyed by Bradford in the ager Lucerinus. This study argues that the farms and associated grids belong to Rome's establishment of a Latin colony at Luceria in 326 or 315/314 BC during the Second Samnite War, and that the farms were abandoned due to the Hannibalic War. This study therefore presents the earliest certain Roman centuriation for a colony, and it observes the devastating impact of Hannibal's invasion and prolonged occupation on landholding in southeastern Italy, which has been doubted in recent work on Italian agrarian history. In no other part of Italy does there exist a coherent group of nearby excavated small-scale farms, which provides new insight into Roman colonization in Apulia and the consequences of the Hannibalic War.

As high-dynamic range (HDR) and wide-color gamut (WCG) contents become more and more popular in multimedia markets, color mapping of the distributed contents to different rendering devices plays a pivotal role in HDR distribution eco-systems. The widely used and economic gamut-clipping (GC)-based techniques perform poorly in mapping WCG contents to narrow gamut devices; and high-performance color-appearance model (CAM)-based techniques are computationally expensive to commercial applications. In this paper, we propose a novel color gamut mapping (CGM) algorithm to solve the problem. By introducing a color transition/protection zone (TPZ) and a set of perceptual hue fidelity constraints into the CIE-1931 space, the proposed algorithm directly carries out CGM in the perceptually non-uniform space, thus greatly decreases the computational complexity. The proposed TPZ effectively achieves a reasonable compromise between saturation preserving and details protection in out-of-gamut colors. The proposed hue fidelity constraints reference the measurements of human subjects' visual responses, thus effectively preserve the perceptual hue of the original colors. Experimental results show that the proposed algorithm clearly outperforms the GC-CGM, and performs similarly or better than the expensive CAM-CGM. The proposed algorithm is real-time and hardware friendly. It is an important supplement of the SMPTE ST.2094-40 standard.

The status of Asian populations of the Eurasian otter Lutra lutra is largely unknown. Since its designation as a Natural Monument (in 1983) and as Endangered (in 1997) in South Korea the authorities there have been trying to conserve and recover the species. We conducted a national otter survey by standard methods in 2017 and compared the current otter distribution to those recorded in a previous survey (2010). We found otter signs in 84.5% of 1,105 10 × 10 km grid cells, with the highest sprainting intensity in the south-west in the Yeongsan River Basin and on the south coast, where we recorded 7.05 and 6.26 spraints/site, respectively. Despite relatively low spraint densities, the otter has expanded its range since 2010 by colonizing urban areas. This trend suggests that South Korea could be a source area for the recovery of the Eurasian otter in East Asia.

Due to the lack of an effective prophylactic intervention and diagnosis, human liver fluke Clonorchis sinensis continues to afflict a large human population, causing a chronic inflammatory bile duct disease. With an aim to identify target antigens for sensitive serodiagnosis, adenylate kinase 3 of C. sinensis (CsAK3) was successfully expressed in soluble form in Escherichia coli by fusion to an RNA-interacting domain derived from human Lys-tRNA synthetase and purified by Ni2+-affinity chromatography. Anti-CsAK3 serum was raised by immunization of mice, and Western blotting confirmed that CsAK3 was expressed in adult-stage C. sinensis. Histochemical analysis showed that CsAK3 was localized to the subtegumental tissue of C. sinensis and was excreted into the bile duct of the host. When tested against sera from various parasite-infected patients by enzyme-linked immunosorbent assay, the recombinant CsAK3 elicited a specific response to C. sinensis-infected sera. The results suggest that CsAK3, either alone or in combination with other antigens, could be used for improving the clinical diagnosis of clonorchiasis.

An essential component for assessing the accuracy and fluency of language learners is understanding how mode of communication and task type affect performance in second-language (L2) acquisition. This study investigates how text-based synchronous computer-mediated communication (SCMC) and face-to-face (F2F) oral interaction can influence the performance of language learners in producing grammatical forms accurately when learners of English as a second language complete different tasks in their L2. Findings show a systematic variability in learner interlanguage that depends on mode of communication and task type. L2 learners used articles more correctly and produced advanced-stage questions more frequently in text-based SCMC than in F2F. These findings suggest that task types and the mode of communication in which a task is completed need careful selection based on pedagogical purposes in order to maximize L2 learning and better evaluate L2 performance.

The Sewol ferry disaster is one of the most tragic events in Korea’s modern history. Among the 476 people on board, which included Danwon High School students (324) and teachers (14), 304 passengers died in the disaster (295 recovered corpses and 9 missing) and 172 survived. Of the rescued survivors, 72 were attending Danwon High School, located in Ansan City, and residing in a residence nearby. Because the students were young, emotionally susceptible adolescents, both the government and the parents requested the students be grouped together at a single hospital capable of appropriate psychiatric care. Korea University Ansan Hospital was the logical choice, as the only third-tier university-grade hospital with the necessary faculty and facilities within the residential area of the families of the students. We report the experiences and the lessons learned from the processes of preparing for and managing the surviving young students as a community-based hospital.

Many transgenic domestic animals have been developed to produce therapeutic proteins in the mammary gland, and this approach is one of the most important methods for agricultural and biomedical applications. However, expression and secretion of a protein varies because transgenes are integrated at random sites in the genome. In addition, distal enhancers are very important for transcriptional gene regulation and tissue-specific gene expression. Development of a vector system regulated accurately in the genome is needed to improve production of therapeutic proteins. The objective of this study was to develop a knock-in system for expression of human fibroblast growth factor 2 (FGF2) in the bovine β-casein gene locus. The F2A sequence was fused to the human FGF2 gene and inserted into exon 3 of the β-casein gene. We detected expression of human FGF2 mRNA in the HC11 mouse mammary epithelial cells by RT-PCR and human FGF2 protein in the culture media using western blot analysis when the knock-in vector was introduced. We transfected the knock-in vector into bovine ear fibroblasts and produced knock-in fibroblasts using the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 system. Moreover, the CRISPR/Cas9 system was more efficient than conventional methods. In addition, we produced knock-in blastocysts by somatic cell nuclear transfer using the knock-in fibroblasts. Our knock-in fibroblasts may help to create cloned embryos for development of transgenic dairy cattle expressing human FGF2 protein in the mammary gland via the expression system of the bovine β-casein gene.
