Academic Organization and Students\u27 Career Formation : A Study of Student Subculture and School Organization in Japanese High Schools (2)
The aim of this study is to find the relations of school organizational structure and non-organizational treatment to students career formation. We studied the relation of "Student Subculture and School Organization in Japanese High school" in 1979, which was reported in this bulletin in 1981. In that study, we showed the importance of school organization and teachers\u27 perspecctives as intervening variables. In this study, we focused on student career formation as an output variable. And we researched how student career formation is influenced by organizational and non-organizational features of the individual school. We tried three case studies. Each case contains two schools which have the same background. By this method, we could clarify school organizational and non-organizational effect on student career formation with any other variables controlled. The data we used are sub-samples of the former study in 1979. The number of the survey objects include 6 high schools, 6 staffs a school, 750 students and 68 teachers
Vocational Guidance and Student\u27s Career Formation (I)
About half of students are planning to enter labor force after graduating from high schools in Japan, so job placement is an integral part of the vocational guidance in high school. It means high school plays an important role in allocating students to labor market. If we try to grasp the selection function of Japanese high schools totally, we have to clarify these allocation processes. In order to explore the processes, we made a nationwide survey including 1,170 high schools (whereby more than half of the students planning to work upon leaving school) using questionnaire method. This is the first report of the survey
A Study of Student Subculture and School Organization in Japanese High Schools (1)
We studied "Appropriate Size of Upper Secondary Schools" in 1976, which was reported in this bulletin in 1978. Then we found the status and the organization of the school had the determinative effects on its student sub-culture. We reviewed other articles on student sub-culture, so we reconstruct the frame of research. It includes two factors, e. g. school organization and teachers\u27 perspectives as intervening \u27 variables. The number of the survey objects include ll high schools, 6 staffs a school, 1,375 students and 604 teachers
The whole blood transcriptional regulation landscape in 465 COVID-19 infected samples from Japan COVID-19 Task Force
「コロナ制圧タスクフォース」COVID-19患者由来の血液細胞における遺伝子発現の網羅的解析 --重症度に応じた遺伝子発現の変化には、ヒトゲノム配列の個人差が影響する--. 京都大学プレスリリース. 2022-08-23.Coronavirus disease 2019 (COVID-19) is a recently-emerged infectious disease that has caused millions of deaths, where comprehensive understanding of disease mechanisms is still unestablished. In particular, studies of gene expression dynamics and regulation landscape in COVID-19 infected individuals are limited. Here, we report on a thorough analysis of whole blood RNA-seq data from 465 genotyped samples from the Japan COVID-19 Task Force, including 359 severe and 106 non-severe COVID-19 cases. We discover 1169 putative causal expression quantitative trait loci (eQTLs) including 34 possible colocalizations with biobank fine-mapping results of hematopoietic traits in a Japanese population, 1549 putative causal splice QTLs (sQTLs; e.g. two independent sQTLs at TOR1AIP1), as well as biologically interpretable trans-eQTL examples (e.g., REST and STING1), all fine-mapped at single variant resolution. We perform differential gene expression analysis to elucidate 198 genes with increased expression in severe COVID-19 cases and enriched for innate immune-related functions. Finally, we evaluate the limited but non-zero effect of COVID-19 phenotype on eQTL discovery, and highlight the presence of COVID-19 severity-interaction eQTLs (ieQTLs; e.g., CLEC4C and MYBL2). Our study provides a comprehensive catalog of whole blood regulatory variants in Japanese, as well as a reference for transcriptional landscapes in response to COVID-19 infection
DOCK2 is involved in the host genetics and biology of severe COVID-19
「コロナ制圧タスクフォース」COVID-19疾患感受性遺伝子DOCK2の重症化機序を解明 --アジア最大のバイオレポジトリーでCOVID-19の治療標的を発見--. 京都大学プレスリリース. 2022-08-10.Identifying the host genetic factors underlying severe COVID-19 is an emerging challenge. Here we conducted a genome-wide association study (GWAS) involving 2, 393 cases of COVID-19 in a cohort of Japanese individuals collected during the initial waves of the pandemic, with 3, 289 unaffected controls. We identified a variant on chromosome 5 at 5q35 (rs60200309-A), close to the dedicator of cytokinesis 2 gene (DOCK2), which was associated with severe COVID-19 in patients less than 65 years of age. This risk allele was prevalent in East Asian individuals but rare in Europeans, highlighting the value of genome-wide association studies in non-European populations. RNA-sequencing analysis of 473 bulk peripheral blood samples identified decreased expression of DOCK2 associated with the risk allele in these younger patients. DOCK2 expression was suppressed in patients with severe cases of COVID-19. Single-cell RNA-sequencing analysis (n = 61 individuals) identified cell-type-specific downregulation of DOCK2 and a COVID-19-specific decreasing effect of the risk allele on DOCK2 expression in non-classical monocytes. Immunohistochemistry of lung specimens from patients with severe COVID-19 pneumonia showed suppressed DOCK2 expression. Moreover, inhibition of DOCK2 function with CPYPP increased the severity of pneumonia in a Syrian hamster model of SARS-CoV-2 infection, characterized by weight loss, lung oedema, enhanced viral loads, impaired macrophage recruitment and dysregulated type I interferon responses. We conclude that DOCK2 has an important role in the host immune response to SARS-CoV-2 infection and the development of severe COVID-19, and could be further explored as a potential biomarker and/or therapeutic target
