On the beginning of the Japanese Upper Paleolithic:A review of recent archaeological and anthropological evidence

The beginning of the Japanese Upper Paleolithic has mainly been examined using two major models:the Middle Paleolithic evolutionary model within the archipelago and the continental Upper Paleolithic diffusion/migration model.However,recent archeological data from Japan and nearby countries are challenging such simple models.This paper critically reviews previous chronology of the Japanese Paleolithic,including possible Lower and Middle Paleolithic(LP/MP),and attempts to show an alternative model of the beginning of the Japanese Upper Paleolithic.This paper suggests several possible specimens of LP/MP and recommends further geoarchaeological investigation to understand the reliability and cultural relationship between possible LP/MP specimens and the Early Upper Paleolithic(EUP).The start of the Japanese EUP is presently characterized by a flake industry with trapezoids and denticulates around 39-37 kaBP cal on Paleo-Honshu Island,which has partial resemblance with contemporary assemblages in China and the Korean Peninsula,although trapezoids are endemic only to the Japanese EUP and may have derived from the ancestral lithic tradition.Blade technology appeared earliest on Central Paleo-Honshu Island,about 1000 years later than the earliest flake technology.Although blade technology may have originated from the elongated flake technology of the previous period,the sudden simultaneous emergence implies that it diffused from the Korean Peninsula.This paper proposes that blade technology from the Korean Peninsula arrived on the northeastern Paleo-Honshu Island,including the Japan Sea coastal region of western Honshu,rather than the southwest,where flake technology long prospered,due to differences in ecological settings and adaptation strategies between the two regions.

Does social information affect the settlement decisions of resident birds in their second breeding attempt?A case study of the Japanese Tit(Parus minor)

Individuals may gather information about environmental conditions when deciding where to breed in order to maximize their lifetime fitness.They can obtain social information by observing conspecifics and heterospecifics with similar ecological needs.Many studies have shown that birds can rely on social information to select their nest sites.The location of active nests and the reproductive success of conspecifics and heterospecifics can provide accurate predictions about the quality of the breeding habitat.Some short-lived species can facultatively reproduce two and/or more times within a breeding season.However,few studies have focused on how multiplebrooding individuals select nest sites for their second breeding attempts.In this study,we use long-term data to test whether the Japanese Tit(Parus minor)can use social information from conspecifics and/or heterospecifics(the Eurasian Nuthatch Sitta europaea,the Daurian Redstart Phoenicurus auroreus and the Yellow-rumped Flycatcher Ficedula zanthopygia)to select a nest site for the second breeding attempt.Our results showed that the nest boxes occupied by tits on their second breeding attempt tended to be surrounded by more breeding conspecific nests,successful first nests of conspecifics,and fewer failed first nests of conspecifics than the nest boxes that remained unoccupied(the control group).However,the numbers of breeding heterospecific nests,successful heterospecific nests,and failed heterospecific nests did not differ between the nest boxes occupied by tits on their second breeding attempt and the unoccupied nest boxes.Furthermore,the tits with local successful breeding experience tended to choose areas with more successful first nests of conspecifics than those without successful breeding experience.Thus,we suggest that conspecifics'but not heterospecifics'social information within the same breeding season is the major factor influencing the nest site selection of Japanese Tits during second breeding attempts.

Serological Investigation into the Infected Genotypes of Patients with Japanese Encephalitis in the Coastal Provinces of China

Objective Genotypes(G)1,3,and 5 of the Japanese encephalitis virus(JEV)have been isolated in China,but the dominant genotype circulating in Chinese coastal areas remains unknown.We searched for G5 JEV-infected cases and attempted to elucidate which JEV genotype was most closely related to human Japanese encephalitis(JE)in the coastal provinces of China.Methods In this study,we collected serum specimens from patients with JE in three coastal provinces of China(Guangdong,Zhejiang,and Shandong)from 2018 to 2020 and conducted JEV cross-neutralization tests against G1,G3,and G5.Results Acute serum specimens from clinically reported JE cases were obtained for laboratory confirmation from hospitals in Shandong(92 patients),Zhejiang(192 patients),and Guangdong(77 patients),China,from 2018 to 2020.Seventy of the 361 serum specimens were laboratory-confirmed to be infected with JEV.Two cases were confirmed to be infected with G1 JEV,32 with G3 JEV,and two with G5 JEV.Conclusion G3 was the primary infection genotype among JE cases with a definite infection genotype,and the infection caused by G5 JEV was confirmed serologically in China.

Japanese Sign Language Recognition by Combining Joint Skeleton-Based Handcrafted and Pixel-Based Deep Learning Features with Machine Learning Classification

Sign language recognition is vital for enhancing communication accessibility among the Deaf and hard-of-hearing communities.In Japan,approximately 360,000 individualswith hearing and speech disabilities rely on Japanese Sign Language(JSL)for communication.However,existing JSL recognition systems have faced significant performance limitations due to inherent complexities.In response to these challenges,we present a novel JSL recognition system that employs a strategic fusion approach,combining joint skeleton-based handcrafted features and pixel-based deep learning features.Our system incorporates two distinct streams:the first stream extracts crucial handcrafted features,emphasizing the capture of hand and body movements within JSL gestures.Simultaneously,a deep learning-based transfer learning stream captures hierarchical representations of JSL gestures in the second stream.Then,we concatenated the critical information of the first stream and the hierarchy of the second stream features to produce the multiple levels of the fusion features,aiming to create a comprehensive representation of the JSL gestures.After reducing the dimensionality of the feature,a feature selection approach and a kernel-based support vector machine(SVM)were used for the classification.To assess the effectiveness of our approach,we conducted extensive experiments on our Lab JSL dataset and a publicly available Arabic sign language(ArSL)dataset.Our results unequivocally demonstrate that our fusion approach significantly enhances JSL recognition accuracy and robustness compared to individual feature sets or traditional recognition methods.

Japanese candlestick charts for diabetes

Continuous glucose monitoring(CGM)is a popular technology among the diabetic population,especially in patients with type 1 diabetes and those with type 2 diabetes treated with insulin.The American Diabetes Association recommends standardization of CGM reports with visual cues,such as the ambulatory glucose profile.Nevertheless,interpreting this report requires training and time for CGM to be cost-efficient.In this work it has been proposed to incorporate Japanese candlestick charts in glucose monitoring.These graphs are used in price analysis in financial markets and are easier to view.Each candle provides extra information to make prudent decisions since it reports the opening,maximum,minimum and closing glucose levels of the chosen time frame,usually the daily one.The Japanese candlestick chart is an interesting tool to be considered in glucose control.This graphic representation allows identification of glucose trends easily through the colors of the candles and maximum and minimum glucose values.

Psychometric Properties among Japanese Women Based on the Multidimensional Assessment of Women’s Experience of Childbirth

Aims/Background: Perceived experiences of childbirth are important for mothers as they affect their self-esteem, mother-child interactions, subsequent mother-child bonding, and their desire for another child. This study examined the factor structure and construct validity of Salmon and Drew’s Multidimensional Assessment of Women’s Experience of Childbirth (MAWEC) in Japanese. Design/Methods: This study conducted a questionnaire survey using the Japanese version of the MAWEC and other variables with 759 women with infants in Japan. The participants’ mean (standard deviation [SD], range) age was 31.9 (5.3, 18 - 46) years. A total of 353 (46.5%) participants were primiparous and 384 (50.6%) were multiparous, and 22 (2.9%) did not answer. The data were randomly divided into two groups for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) and separately analyzed the positive- and negative-worded items. I conducted EFA using the maximum-likelihood method with PROMAX rotation from one-through two- and three-factor structures. Different factor structure models were compared in terms of CFAs using, as indicator of goodness-of-fit, chi-square/df, comparative fit index (CFI), and root mean square of error approximation (RMSEA). Results: This study showed that a bifactor model for the MAWEC with four subscales (positive emotion, positive coping, negative emotion, and negative coping) fit the data the best. These four subscales were associated with demographic, obstetric, neonatal, and feeding characteristics. For example, primiparas were more vulnerable to coping aspects of perceived childbirth experiences, including sense of mastery over the delivery process and ability to enjoy the delivery. Gestational age at birth was associated with emotional aspects of perceived childbirth experiences. Conclusion: The Japanese version of the MAWEC consists of four aspects regarding perceived childbirth experience. Perinatal health professionals may examine women’s childbirth experiences from these four perspectives. .

Appropriate leucine-richα-2 glycoprotein cut-off value for Japanese patients with ulcerative colitis

BACKGROUND It has been suggested that serum leucine-richα-2 glycoprotein(LRG)could be a novel monitoring biomarker for the assessment of disease activity in inflammatory bowel disease.In particular,the relationship between LRG levels and the endoscopically assessed activity of ulcerative colitis(UC)has become a matter of interest.AIM To clarify appropriate LRG cut-off values for the prediction of endoscopic and histologic remission in Japanese patients with UC.METHODS This was a cross-sectional,single-center,observational study of Japanese patients with UC.Among 213 patients with UC,in whom LRG was measured from September 2020 to February 2022,we recruited 30 patients for whom a total colonoscopy and measurements of LRG and C-reactive protein(CRP)were performed on the same day.We retrospectively analyzed correlations between the LRG and CRP levels and endoscopic indices,including the Mayo endoscopic subscore and UC endoscopic index of severity.RESULTS Correlations between the LRG values and the Mayo endoscopic subscore or UC endoscopic index of severity were significant(r=0.754,P<0.0001;r=0.778,P<0.0001,respectively).There were also significant correlations between CRP levels and Mayo endoscopic subscore or UC endoscopic index of severity(r=0.599,P=0.0005;r=0.563,P=0.0012,respectively),although the correlation coefficients were higher for LRG.The LRG cutoff value for predicting endoscopic remission was 13.4μg/mL for a Mayo endoscopic subscore of 0[area under the curve(AUC):0.871;95%confidence interval(CI):0.744-0.998],and 13.4μg/mL for an UC endoscopic index of severity of 0 or 1(AUC:0.904;95%CI:0.792-1.000).CONCLUSION LRG may be a surrogate marker for endoscopic activity in UC,with a cut-off value of around 13.4μg/mL for endoscopically inactive disease.

The Exploration of Identity and Belonging in Post-World War II German Literature

The research paper explores belongingness and identity in post-WWII German literature through the lens of iconic scholars,including Wolf,Şenocak,and Grass.The three authors are central and prominent figures in building German literature in the aftermath of the war.National divisions in Germany,rebuilding destroyed communities,and guilt struggles marked this literature.German authors utilized literature during the war to question and comprehend fractures,structures,and the comprehensive identity of a nation with issues of guilt,war,splitting,differences,and divisions.By comprehensively linking Wolf and Grass’authorships to modern debates on multiculturism and migration,we derive fundamental insights and ideas into their applicability to issues affecting our world today.Some of the contemporary issues are immigration,civil wars,and trauma affecting people.Authors like Grass had a significant role to play during post-WWII in Germany,like dealing with and handling migrant and refugee experiences,returning of soldiers,the Holocaust,and the hardships of life.

Multimodal Metaphor Analysis of German Commercials

This research examines the characteristics of multimodal metaphors utilized by German advertisers in their commercial designs.Commercial advertisements inherently incorporate a diverse array of communicative symbols,encompassing textual,visual,and auditory elements,which collaboratively function to construct metaphoric representations.Consequently,these advertisements are characterized by a rich presence of multimodal metaphors,strategically crafted to leave a lasting impression on viewers and to stimulate the purchasing intentions of targeted demographics.Employing a cognitive linguistics framework,this paper conducts a comparative analysis of the multimodal metaphors present in three exemplary German commercials:K-fee,Coca-Cola Zero,and Pure Milk.The findings illuminate the effective deployment of multimodal strategies in enhancing message transmission and fostering consumer engagement within the advertising landscape.
