概要: Two field trials were conducted in Northern Thailand from 2018 to 2020 to determine the best manual harvesting method fo r maximizing seed yield and seed quality of two Urochloa ruziziensis cultivars, cv. OKI-1 and cv. Br-203. Four manual seed harvesting methods were implicated in a randomized complete block design with four replicates. The four methods were as follows: knocking seeds from seedheads into a nylon net receptacle and collecting them once every day (T1); knocking seeds from seedheads into a nylon net receptacle and collecting them once every three days (T2); allowing ripe seeds to fall into a nylon net sheet that was stretched as a receptacle beneath the seedheads and collecting seeds once every five days (T3); and covering the tied seedheads with a nylon net bag and collecting seeds once every five days (T4). The highest pure seed yield was obtained from T3 in cv. Br-203 (333.11 kg/ha), as well as the highest trend in cv. OKI-1 (534.67 kg/ha). T3 produced 22–46% and 11–27% more pure germinated seed yields than the other methods in cv. Br-203 and cv. OKI-1, respectively. As a result, T3 was recommended for higher seed yield, convenient seed harvest, and reduced manual seed harvest time. 続きを見る

概要: This study evaluates land use transformation in Kandahar’s old city, also known as Ahmad Shahi city, the birthplace and first capital of modern Afghanistan. The city consists of four rectangular quarters and is surrounded by a high strong mud wall, entrance gates, and a moat. In the early 20th century, the city experienced significant and arbitrary expansion, which certainly affected the urban fabric of the area, the streets were widened, and the city wall, towers, and gates were demolished, and the area was added to the construction of new government buildings, commercial establishments, and residential plots. This study aims to evaluate the alterations in the old city’s urban morphology, culture, and sociology by conducting a comparative analysis of three maps from different time periods and considering various factors within the target area. 続きを見る

概要: We provide explicit expressions for two types of first order q-difference systems for the Jackson integral of symmetric Selberg type. One is the q- difference system known to be the q-KZ equation and the other is the q-difference system for parameters different from the q-KZ equation. We use a basis of the systems introduced by Matsuo in his study of the q-KZ equation. As a result, the similarity of these two systems is discussed by concrete calculations. Interme- diate calculations are made use of the Riemann-Hilbelt method for q-difference equation from connection matrix established by Aomoto. 続きを見る

概要: Phytoplanktonic dinoflagellates form colonies between vertical ice crystals during the icemelting season in Lake Baikal, but how the plankton survive the freezing conditions is not known. Here we show that the phytoplankton produces large amounts of dimethylsulfoniopropionate (DMSP), which is best-known as a marine compound. Lake-water DMSP concentrations in the spring season are comparable with those in the oceans, and colony water in ice exhibits extremely high concentrations. DMSP concentration of surface water correlates with plankton density and reaches a maximum in mid-April, with temperature-dependent fluctuations. DMSP is released from plankton cells into water in warm days. DMSP is a characteristic osmolyte of marine algae; our results demonstrate that freshwater plankton, Gymnodinium baicalense, has DMSP-producing ability, and efficiently uses the limited sulfur resource (only 1/500 of sea sulfate) to survive in freshwater ice. Plankton in Lake Baikal do not need an osmolyte, and our results clearly indicate that DMSP plays a cryoprotective role. DMSP, although a characteristic marine compound, could also be an important zwitterion for algae of other boreal lakes, alpine snow, and glaciers. 続きを見る

概要: Background: Root system architecture is an important trait affecting the uptake of nutrients and water by crops. Shallower root systems preferentially take up nutrients from the topsoil and help avoid unfavorable environments in deeper soil layers. We have found a soil-surface rooting mutant from an M2 population that was regenerated from seed calli of a japonica rice cultivar, Nipponbare. In this study, we examined the genetic and physiological characteristics of this mutant. Results: The primary roots of the mutant showed no gravitropic response from the seedling stage on, whereas the gravitropic response of the shoots was normal. Segregation analyses by using an F2 population derived from a cross between the soil-surface rooting mutant and wild-type Nipponbare indicated that the trait was controlled by a single recessive gene, designated as sor1. Fine mapping by using an F2 population derived from a cross between the mutant and an indica rice cultivar, Kasalath, revealed that sor1 was located within a 136-kb region between the simple sequence repeat markers RM16254 and 2935-6 on the terminal region of the short arm of chromosome 4, where 13 putative open reading frames (ORFs) were found. We sequenced these ORFs and detected a 33-bp deletion in one of them, Os04g0101800. Transgenic plants of the mutant transformed with the genomic fragment carrying the Os04g0101800 sequence from Nipponbare showed normal gravitropic responses and no soil-surface rooting. Conclusion: These results suggest that sor1, a rice mutant causing soil-surface rooting and altered root gravitropic response, is allelic to Os04g0101800, and that a 33-bp deletion in the coding region of this gene causes the mutant phenotypes. 続きを見る

概要: Adult female and immature specimens of Typopeltis crucifer Pocock, 1894, were collected from Taramajima Island, Sakishim a Islands, southwestern Japan. A phylogenetic tree built using the mitochondrial COI gene (620 bp) of T. crucifer from Sakishima Islands revealed that specimens from Ishigakijima Island comprised two genetic groups. One of these groups formed a clade with specimens from Taramajima Island, and the other group was closely related to specimens from Iriomotejima Island. Our finding indicates that phylogeographic analyses on soil-dwelling invertebrates are expected to provide new insights into the paleogeographic processes that have shaped the Ryukyu Islands.

概要: A survey of Montipora corals fauna was conducted around Minami-Daitojima Island in June 2022 and a total of eight specie s (Montipora nodosa, Montipora sp. OKINAWATOGE, M. peltiformis, M. sinensis, M. stalagmites, M. turgescens, M. venosa and Montipora sp.) were recorded. Of these species, M. stalagmites was recorded for the first time in the 135 years since it was originally described. The species richness of the Montipora of Minami-Daito Island is very low when compared to other islands of the Ryukyu Archipelago. This is presumably because of the severe habitat environment of this oceanic island which has a steeply sloping bathymetry, little reef development, and extremely high wave energy.

概要: Mongolian residential sector including houses and Gers, which are traditional dwellings, becomes not only the biggest en ergy consumer but also produces the highest share of emissions because of the significant increase of utilizing traditional stoves with solid fuels such as charcoal and wood in wintertime. The aim of the thesis is to seek possibilities of a grid-connected solar photovoltaic (PV) system for Mongolian houses/Gers so as to improve the access to electricity and reduce greenhouse gases simultaneously. Solar PV system is considered as ease of installation, less maintenance and the absence of rotation. Moreover, utilizing the proposed system provides the residents much more opportunities such as self-usage and trading the surplus energy to the grid. Due to the mismatch between PV array production and demand, the necessity for battery storage systems increases. Therefore, the battery storage system is included to increase self—consumption. However, depending on tariff structure, consumption, and production, the availability of the systems might be adapted. This dissertation seeks to investigate the possibilities of deploying the grid-integrated residential PY-battery system for Mongolian houses and develop a viable configuration. To investigate the possibilities of the PY-battery system for Mongolian conditions, to begin with, we investigated the current electricity tariff market, household load consumption, and PV generation potential. A simulation model including the PV array, battery storage system, and load for the private house/Ger is developed with historical data. A simple operation strategy based on FIT tariff mechanism using PSIM software is studied. Thereafter, the impacts of numerous households with the PY-battery system on the low-voltage network were investigated. This can be implemented effectively in Mongolian households. It confrrms that tons of harmful emissions can be reduced. 続きを見る

概要: The ethnic makeup of Kabul, the capital of Afghanistan, is diverse, with Pashtun, Tajik, Hazara, and Uzbek ethnic groups making up the majority. These distinct culturally rooted groupings are further split based on where they are from geographically within the nation. Following the civil war (1992—1996), which fueled ethnic polarization and spawned strategic clusters within the city, these differences have grown even more prominent. The current study examines ethnic segmentation in Kabul City, particularly emphasizing how historical and modern urban planning initiatives have addressed these disparities. We began by thoroughly assessing the literature on ethnic segregation in urban areas and the existence of ethnic and sub-ethnic groupings in Afghanistan. A化er that, we looked closely at Kabul's formal planning history and considered how the government dealt with ethnic segmentation and urban development. According to our research, smaller sub-ethnic communities are created due to people migrating from rural areas and the return of immigrants. These groups of people are connected by a shared identity known as "Qawm," in which community mosques as communal buildings play a crucial role. Additionally, we discovered that ethnicity significantly influenced Kabul residents'preferences for where to live. We reviewed the five master plans created for Kabul City. Early master plans had little involvement from the community and were essentially technocratic and authoritarian. However, in the fourth master plan (2011), there was a turn toward participatory planning. The most recent urban design framework shows an uneven distribution of economic, administrative, and facility hubs across ethnic groups and looks to have declined in terms of participatory planning. In order to sustain communal cohesion, this study recommends that policymakers consider ethnic and sub-ethnic components in urban planning. The study highlights the need for more thoroughylans to address ethnic division to prevent the city from becoming further polarized. 続きを見る

概要: The combination effects of smoking (SMK) and hyperuricemia (HU) on renal arteriolosclerosis in patients with IgA nephrop athy remain unknown. We examined the cross-sectional association between smoking (current or former) and renal arteriolar hyalinosis and wall thickening with or without HU [uric acid (UA) level 7 and 5 mg/dL in men and women] in 87 patients with IgA nephropathy who underwent renal biopsy. Arteriolar hyalinosis and wall thickening were assessed by the semiquantitative grading of arterioles. The SMK/HU subgroup showed the highest indices for hyalinosis and wall thickening, followed by the non-SMK/HU, SMK/non-HU, and non- SMK/non-HU subgroups. Multiple logistic analysis showed that SMK/HU, but not SMK/non-HU, was significantly associated with an increased risk of higher-grade renal arteriolar wall thickening. However, this did not occur with hyalinosis compared to non-SMK/non-HU. The adjusted odds ratio (95% confidence interval, p value) for SMK/HU was 12.8 (1.36–119, p < 0.05) for wall thickening. An association between SMK and renal arteriolar wall thickening might be prevalent only among patients with HU and in patients with IgA nephropathy. Further prospective studies are needed to determine whether patients with HU and SMK history exhibit rapid eGFR deterioration. 続きを見る

概要: Aim: Continued antipsychotic treatment is the key to preventing relapse. Maintenance antipsychotic monotherapy and optimal dose use are recommended for individuals with stable schizophrenia because of their undesirable effects. Decision aids (DAs) are clinical conversation tools that facilitate shared decision-making (SDM) between patients and health-care providers. This study aimed to describe the development process and results of acceptability testing of a DA for individuals with stable schizophrenia, considering (i) whether to continue high-dose antipsychotics or reduce to the standard dose and (ii) whether to continue two antipsychotics or shift to monotherapy. Methods: A DA was developed according to the guidelines for the appropriate use of psychotropic medications and International Patient Decision Aid Standards (IPDAS). First, a DA prototype was developed based on a previous systematic review and meta-analysis conducted for identifying the effects of continuing or reducing antipsychotic treatment. Second, mixed-method survey was performed among individuals with schizophrenia and health-care providers to modify and finalize the DA. Results: The DA consisted of an explanation of schizophrenia, options to continue high-dose antipsychotics or reduce to the standard dose, options to continue two antipsychotics or shift to monotherapy, pros and cons of each option, and a value-clarification worksheet for each option. The patients (n = 20) reported acceptable language use (75%), adequate information (75%), and well-balanced presentation (79%). Health-care providers (n = 20) also provided favorable overall feedback. The final DA covered six IPDAS qualifying criteria. Conclusion: A DA was successfully developed for schizophrenia, considering whether to reduce antipsychotics, which can be used in the SDM process. 続きを見る

概要: We propose a framework to analyze the relationship between the movement features of a wheel gymnast around the mounting phase of Unit 2 of the vault event and execution (Escore) deductions from a machine-learning perspective. We first developed an automation system from a video of a wheel gymnast performing a tuck-front somersault to extract the four frames highlighting its Unit 2 performance of the vault event, such as take-off, pikemount, the starting point of time on the wheel, and final position before the thrust. We implemented this automation using recurrent all-pairs field transforms (RAFT) and XMem, i.e., deep network architectures respectively for optical flow estimation and video object segmentation. We then used a markerless pose-estimation system called OpenPose to acquire the coordinates of the gymnast’s body joints, such as shoulders, hips, and knees then calculate the joint angles at the extracted video frames. Finally, we constructed a regression model to estimate the E-score deductions during Unit 2 on the basis of the joint angles using an ensemble learning algorithm called Random Forests, with which we could automatically select a small number of features with the nonzero values of feature importances. By applying our framework of markerless motion analysis to videos of male wheel gymnasts performing the vault, we achieved precise estimation of the E-score deductions during Unit 2 with a determination coefficient of 0.79. We found the two movement features of particular importance for them to avoid significant deductions: time on the wheel and angles of knees at the pike-mount position. The selected features well reflected the maturity of the gymnast’s skills related to the motions of riding the wheel, easily noticeable to the judges, and their branching conditions were almost consistent with the general vault regulations. 続きを見る

概要: Delayed sleep–wake phase disorder (DSWPD) is a sleep disorder in which the habitual sleep–wake timing is delayed, result ing in difficulty in falling asleep and waking up at the desired time. Patients with DSWPD frequently experience fatigue, impaired concentration, sleep deprivation during weekdays, and problems of absenteeism, which may be further complicated by depressive symptoms. DSWPD is typically prevalent during adolescence and young adulthood. Although there are no studies comparing internationally, the prevalence of DSWPD is estimated to be approximately 3% with little racial differences between Caucasians and Asians. The presence of this disorder is associated with various physiological, genetic and psychological as well as behavioral factors. Furthermore, social factors are also involved in the mechanism of DSWPD. Recently, delayed sleep phase and prolonged sleep duration in the young generation have been reported during the period of COVID-19 pandemic-related behavioral restrictions. This phenomenon raises a concern about the risk of a mismatch between their sleep–wake phase and social life that may lead to the development of DSWPD after the removal of these restrictions. Although the typical feature of DSWPD is a delay in circadian rhythms, individuals with DSWPD without having misalignment of objectively measured circadian rhythm markers account for approximately 40% of the cases, wherein the psychological and behavioral characteristics of young people, such as truancy and academic or social troubles, are largely involved in the mechanism of this disorder. Recent studies have shown that DSWPD is frequently comorbid with psychiatric disorders, particularly mood and neurodevelopmental disorders, both of which have a bidirectional association with the pathophysiology of DSWPD. Additionally, patients with DSWPD have a strong tendency toward neuroticism and anxiety, which may result in the aggravation of insomnia symptoms. Therefore, future studies should address the effectiveness of cognitive-behavioral approaches in addition to chronobiological approaches in the treatment of DSWPD. 続きを見る
