The Japanese Bridge Management System (J-BMS) RC version consists of the following three subsystems: (1) a bridge maintenance database system (J-BMS DB), (2) a concrete bridge rating expert system (RC-BREX) and (3) a maintenance plan optimization system (MPOS). Especially, in this paper, the RC-BREX system for deteriorating concrete bridges is described based on how to construct from a hierarchical neural network in order to carry out fuzzy inference and machine learning by using the neural network with the back-propagation method. Furthermore, the comparisons between diagnostic results by bridge experts and those of the proposed system are presented so as to demonstrate the validity of the system’s learning capability by using the training set for machine learning which obtained from inspection on actual in-service bridges and questionnaire surveys by bridge experts.

Taiwan has not yet been singed the “Convention on Nuclear Safety; CNS” that was adopted by the International Atomic Energy Agency (IAEA) in 1994. However, if these international activities help promote nuclear safety, Taiwan must participate in it and fulfill its related obligations. Therefore, despite Taiwan being a non-member state to the CNS, it is required by the Convention to act as a member state to meet all the requirements addressed in the CNS. Ensuring the public trust of nuclear safety regulations in the most important policy issue for the location, operation, waste disposal and off-commissioning of nuclear power plants, etc. As part of an international comparison of nuclear safety regulatory bodies in the East Asian region, this note organizes and evaluates the independence and transparency of Taiwan’s regulatory bodies.

Abstract Background: Expanding nursing workload is a worldwide problem. However, any nursing workload assessment (NWA) tool requires complicated analyses of the nursing job profile. To determine the imbalance in time assignments across all nursing operations and to reduce nursing workload, a nursing job survey was conducted. Methods: A total of 25 major job categories, common to all hospital wards, were identified, and an NWA tool was developed for efficient analyses to feature easy/flexible entry of the time spent for each job category and real-time visual profiling of job time allocation. The profile could be divided by job categories, wards, shifts, and years. Results: From the preliminary analyses, undesirable time allocation was revealed in several job categories, especially the time for recording and other nonessential nursing operations. Using the analytical functions of the NWA tool between 2014 and 2016, a series of corrective measures were successfully taken to many job categories, and they were found to be effective. Consequently, excessive overtime workload was reduced from 125 min/day/nurse in 2014 to 100 and 100 min/day/ nurse in 2015 and 2016, respectively. Conclusion: Notable improvements in nursing workload and time allocation for attentive patient care could be achieved employing the novel user-aimed NWA tool.

Abstract Purpose: The purpose of this study was to investigate the effects of two different postures (sitting and standing) and three different ambient temperatures (10℃, 20℃, and 30℃) on heart rate variability (HRV) among healthy young adults. Methods: Twelve young adult volunteers (males 6, females 6) were recruited. Following acclimatization to any the room temperature (10℃, 20℃ or 30℃), 5-min measurements of HRV were conducted in sitting and standing postures of the subjects. Results: Compared to the sitting posture, measurements obtained in the standing posture revealed a significant decrease in high-frequency power/HF, root mean square of successive differences between RR intervals, standard deviation of Poincaré plot perpendicular to the line-of-identity or SD1 and SD1/standard deviation of Poincaré plot along the line-of-identity or SD2, and a significant increase in lowfrequency power/LF and LF/HF under all experimental conditions (p<0.05 to 0.005). Majority of HRV parameters showed significant differences while the values obtained under 10℃ were compared with 20℃ and 30℃ conditions, respectively (p<0.05 to 0.001). Conclusions: Our findings suggest the predominance of sympathetic tone in the standing compared with sitting posture. Furthermore, colder conditions caused a predominance of the parasympathetic activity in both sitting and standing postures, and such effects of ambient temperature on the sympathovagal balance were stronger in the latter posture.

Abstract Background: Recently, the importance of nutritional management in pressure ulcer control has been pointed out. In this study, we analyzed the relationship between nutritional indicators and the presence or absence of pressure ulcers in order to reveal the importance of nutritional management in pressure ulcer control. Method: We investigated 407 inpatients for blood tests, height, weight, BMI, the Ohura-Hotta (OH) scale, nutrition method, living independence, and the presence or absence of pressure ulcers. Results: In the comparison of patients with and without pressure ulcer, significant differences were found in gender, nutrition method, serum total protein, serum albumin, hemoglobin concentration, and the OH scales. Multiple logistic regression analysis showed that gender, intravenous nutrition, serum albumin levels, and the OH scale were associated with the presence or absence of pressure ulcers. The results suggest that not only the OH scale, but the nutritional support was also important in the prediction of the pressure ulcer. It was suggested that shifting from intravenous feeding to tube feeding or oral feeding is important. Conclusion: we found that pressure ulcer was related to gender, intravenous nutrition, serum albumin level and the OH scale. The importance of nutritional management for pressure ulcer prevention was confirmed.

Abstract Objectives: This study examined the short-term outcomes of endovascular therapy (EVT) with the GORE VIABAHN VBX (VBX) which is a balloon-expandable covered stent in patients with aortoiliac occlusive disease (AIOD) and acute limb ischemia (ALI). Methods: This was a single-center retrospective review of patients with AIOD and ALI who underwent EVT with the VBX between December 2018 and January 2021. Primary, assisted, and secondary patency rates were assessed, along with 30-day mortality rates. Results: Twenty-two patients underwent EVT with the VBX; 18 patients had AIOD, whereas 4 had ALI. The incidence of TransAtlantic Intersociety Classification II D lesions was 50% (n=9). Technical success was 100%. One patient with unilateral common iliac artery stenosis developed an intraoperative dissection of the distal edge of the VBX, which required an additional self-expanding VIABAHN stent on the distal edge of the VBX. The primary patency rate at 24 months was 100%. No patients required additional target vessel treatment at a median follow-up of 10 months (range, 1-27). EVT was also successful in the four patients with ALI, who had no complications of the target vessel. Conclusion: The present study demonstrated that EVT with the VBX is effective for AIOD and ALI.

To date, the process of implementing the global Sustainable Development Goals (SDGs) and global climate change mitigation and adaptation obligations has been largely decoupling in most countries. This creates administrative duplication, costs, and hinders the development of effective problem solving. Against this background, we show the present state of research on policy integration and integrated policymaking. Following the research results of Bauer et al. (2021) and Teebken et al. (2021), this note briefly summarizes different understandings of policy integration and detailed criteria for evaluating policy integration from different academic perspectives. Implementing an interactive agenda requires political attention and institutional competence to address the interactions and complexity of each, understand policies at a national level, and translation. In this note, we will introduce the basic concept of what integration practice looks like, and focusing on the interaction between the 2030 Agenda and the Paris Agreement.

This paper empirically examines the impacts of household debt and leverage ratio, measured by the ratio of aggregate household debt to GDP, on consumption using provincial-level macro-data in China. Results show that household indebtedness has a positive and significant effect on consumption expenditure and this remains true for both household debt and leverage ratio, as well as long-term and short-term debts and leverage ratios, and the encouraging effects are heterogeneous across regions. When the debt-to-GDP ratio is below 100%, the consumption experiences faster growth than that when the debt-to-GDP ratio exceeds 100%. In addition, residents’ saving, per capita disposal income and the public expenditure on education, social security, as well as medical and health services are found to have significant positive effects on consumption, while CPI and child dependency ratio have depressive effects.

As income levels increase, numerous households will consider investing in risky assets. Credit availability, especially for high-income households, is playing an increasingly important role in enhancing households holdings of risky assets (HHRA). The purpose of this study is to investigate the impact of credit availability on HHRA. In this study, the data from the China Household Finance Survey in 2017 is utilized, and the approach of logit regression is employed to produce more accurate estimates. Meanwhile, this study also explores the heterogeneous roles of household income. The results show that the impact of credit availability on HHRA varies by household income. As household income increases from low to high, the effect of credit availability on HHRA transfers from negative to positive. Besides, the results also suggest that for high-income households, credit availability moderated with the attention to financial and economic information positively contributes to HHRA. Thus, it implies that policymakers and financial institutions are encouraged to expand access for households to invest in risky assets, enhance households’ availability of credit, and build more financing channels.

The establishment of the environmental protection law reflects the Chinese government's determination to achieve ecological civilization. Since January 1, 2015, when the revised Environmental Protection Law of the People's Republic of China came into effect, environmental public interest litigation in China has been rapidly growing. In the implementation of environmental law, environmental public interest litigation plays an irreplaceable role. The mechanism of environmental public interest litigation will ideally enhance the effectiveness and prevention of environmental protection and become a major contributor to public awareness of environmental protection. Despite the fact that environmental public interest litigation in China has made great progress, there are still many shortcomings and defects. One of the major difficulties facing environmental public interest litigation in China is the lack of standing of plaintiffs in environmental public interest litigation. This paper will explore the necessity of plaintiff status for environmental public interest litigation in China's grassroots self-governance organizations based on the situation of environmental pollution in rural China, using village committees as an example.

As global warming continues to intensify, how to prevent climate deterioration has become a serious concern for all countries. In recent years, although China’s GDP has leap to the second place in the world after the United States, it is accompanied by serious problems of environmental pollution and energy consumption with the rapid development of the economy. Under the common goal of global energy conservation and emission reduction, China has established seven carbon trading markets. Because the energy-chemical industry is a major concern for emission reduction and the carbon trading market has market regulation functions, examining the relationship between them is of great significance and can help the emission reduction effort. This study investigates the relationship between the carbon emission price of China's carbon trading market and the stock price of 30 listed companies in the energychemical industry. We use daily data to establish a panel model and var model, and then compare it with European Emissions Trading Scheme (EU-ETS). The result indicates that there is an asymmetric one-way relationship between the carbon emission price and the stock price of the energy-chemical industry in China. The main reason is that the internal endogenous mechanism and external response mechanism of the carbon trading market are not perfect. Then the government should improve relevant legal system and trading system, and furthermore, introduce third-party institutions and strengthen talent pools.

Consumer capability refers to the ability to apply relevant knowledge and perform desirable behavior for achieving wellbeing. Previous research reveals that consumer behavior is more important than knowledge to indicate consumer capability. How to motivate individual consumers to engage in consumption activities that contribute to sustainable development? This is the question this conceptual paper attempts to address. This paper proposes a definition of sustainable consumer behavior and applies a theory-based, conceptual framework to develop action-taking programs in sustainable consumption education. Sustainable consumer behavior is defined as consumer acts that consider current and future interests of themselves and others when they purchase and use market goods. The behavior change theory used here refers to the transtheoretical model of behavior change (TTM), a commonly used behavior change theory in health and finance. The paper demonstrates how to facilitate the development of sustainable consumer behavior in education intervention programs based on principles outlined in TTM with specific examples. Implications for policies and future research are also discussed.

The purpose of this study was to compare demographic trends in the aging of the Japanese and Brazilian populations on the basis of health indicator data collected by the statistics bureaus of the Japanese and Brazilian governments. The demographic and health indicator data from surveys by the Statistics Bureaus of the Japanese and Brazilian governments and other sources were obtained from websites. The data showed that Japan has an aging population, that the number of elderly persons in Japan is increasing and that the Government of Japan has a plan to address future demands for health resources by this aging population, whereas Brazil has a rapidly population aging but no plan for its future health services. Brazil may need to increase the number of hospitals and hospital beds and develop a medical care plan for the elderly within its Unified Health System.

Histopathological and immunohistochemical studies were conducted to investigate the local existence and distribution of mast cells, fibroblasts or dendritic cells, and myofibroblasts in scleroderma, while paying particular attention to the interstices around the adnexa. The skin tissues in 15 cases of systemic scleroderma were classified histopathologically into three stages: early, fully developed, and late stage. Mesenchymal cells were distinguished immunohistochemically by 6 markers: tryptase, CD34, factor XIIIa, alpha smooth muscle actin (αSMA), vimentin, and desmin. In scleroderma, there was an increase in the number of tryptase-positive mast cells in the interstices around the adnexa. With no relation to the interstitial sites, there was a significant decrease in the number of CD34-positive cells in the late stage, and a significant increase in αSMA-positive cells in the fully developed stage, but a decrease in the late stage. Results of the present study brought about the following new findings: it was only in the mast cells that there was a significant difference in the cell distribution between the interstices around the adnexa and the interstices in non-adnexal sites. Secondly, it was suggested that mast cells, CD34-positive dendritic cells, and αSMA-positive myofibroblasts were involved in the fibrosis and shrinkage or disappearance of the adnexa when scleroderma developed.

Hepatocellular carcinoma (HCC) has a poor prognosis even after curative surgery, due to the high frequency of early intrahepatic recurrence (IHR). Conventional staging systems are almost completely inadequate, and need to be complemented by novel tools. To this end, many investigators have performed DNA microarray analysis on the basis of genome-wide information. However, so far, few studies have been able to truly account for the clinical efficacy of DNA microarray analysis in HCC. To address this dilemma, we used a supervised learning method with information of 7070 genes from 33 HCC samples, to construct a 12-gene predictor for early IHR, and then evaluated its predictive performance in 27 independent HCC samples. Our 12-gene predictor correctly predicted early IHR or non-recurrence in 25 (93%) of the 27 independent samples. This predictive value is higher than that of any other system currently available, suggesting that our system can serve as a robust tool for accurate prediction of early IHR of HCC. I emphasize in this mini-review that, although there are some technical issues to resolve prior to clinical use, DNA microarray technology can provide molecular basis to initiate “bench to bedside” translation, which cannot be easily reached with other methods.

Application of cell therapy using stem cell into intractable diseases has been noted as the medicine in the next generation taking the place of organ transplantation. Bone marrow cells have been focused as a candidate of the source of this therapy. Liver failure is a terminal state of all advanced liver diseases and thousands of patients are dying of decompensated liver cirrhosis in every year in Japan. Liver transplantation must be the strongest weapon to relieve those patients. However, particularly in Japan, liver transplantation has not been popularized. In this sense, we thought of autologous bone marrow cells transplantation for decompensated liver cirrhosis. Basic studies using animal model revealed that transplanted bone marrow cells into syngenic mouse suffering from liver cirrhosis migrated into the damaged liver and transdifferentiated to the hepatocytes. Based upon the animal studies, clinical trial of this new cell therapy supported by the Ministry of Health, Labor and Welfare is ongoing. It is early to estimate this therapy. However, free from liver failure has been observed in some cases.

Incontinentia pigmenti (IP; OMIM# 308300) is a rare inherited disease caused by a mutation of IKBKG, which is also known as NEMO, located on Xq28. IP patients usually present with abnormalities of skin, eyes, nails and central nervous system. The neurological damege, which occur usually from neonatal through the early infantile period, leads to neulogical complication such as development retardation, motor paralysis and epilepsy. However, there has been little study done concerning the effect of therapy for the neural abnormalities. We have investigated the clinical findings in a female IP case with a novel mutation of IKBKG for six years due to disclosing the neurological prognosis and the immunological features. It is hoped that the present study will contribute to a better management of IP patients.

The hippocampal dentate gyrus has been identified to play a critical role in maintaining contextual memory in many mammalian species. To evaluate learninginduced synaptic plasticity of granule cells, we subjected male rats to an inhibitory avoidance (IA) task and prepared acute hippocampal slices. In the presence of 0.5 μM tetrodotoxin, we recorded miniature excitatory post synaptic currents (mEPSCs) and inhibitory post synaptic currents (mIPSCs) in male rats experiencing four groups: untrained, IA-trained, unpaired, and walk-through. Compared with the untrained, IA-trained, unpaired, and walk-through groups, the unpaired group significantly enhanced mean mEPSC amplitudes, suggesting the experience-induced plasticity at AMPA receptor-mediated excitatory synapses. For inhibitory synapses, both unpaired and walk-through groups significantly decreased mean mIPSC amplitudes, showing the experience-induced reduction of postsynaptic GABAA receptor-mediated currents. Unlike the plasticity at CA1 synapses, it was difficult to explain the learning- specific plasticity at the synapses. However, overall multivariate analysis using four variables of mE(I)PSC responses revealed experience-specific changes in the diversity, suggesting that the diversity of excitatory/inhibitory synapses onto granule cells differs among the past experience of animals include the learning. In comparison with CA1 pyramidal neurons, granule cells consistently showed greater amplitude and frequency of mE(I)PSCs. Fluctuation analysis further revealed that granule cells provide more postsynaptic AMPA receptor channels and greater single-channel current of GABAA receptors of than CA1 pyramidal neurons. These findings show functional differences between two types of principal cells in the hippocampus.

Androgen receptor (AR)-signaling plays an important role in promoting tumor cell survival and the development of castration-resistant prostate cancer (CRPC). Androgen deprivation therapy is the basic therapeutic strategy for AR signaling blockade, but that effects wonʼt last long and most of metastatic prostate cancer show castration resistance. Recently, new agents, AR Axis Targeted agents (ARAT), have been developed. We have been developing our bench-to-bedside translational research to elucidate the mechanisms of drug resistance in prostate cancer. This review describes our investigational results and recent advances in CRPC with ARAT treatment strategy.

We study the diffusion of Brownian particles in a Gaussian random velocity field with short memory. By extending the derivation of an effective Fokker–Planck equation for the Lanvegin equation with weakly colored noise to a random velocity-field problem, we find that the effect of thermal noise on particles is suppressed by the existence of memory. We also find that the renormalization effect for the relative diffusion of two particles is stronger than that for single-particle diffusion. The results are compared with those of molecular dynamics simulations.

本研究は新型コロナウイルス影響下の2020年及び2021年に本学F学部に入学した学生163名を対象に, 入学当初である4~7月の歩数を調査した。歩数は各自が所有するスマートフォンに保存されている数値とした。本学の2020年4~7月の授業形態はオンライン授業, 2021年4~7月は対面授業が主であった。調査の結果, 2020年入学生の歩数(2811±1418歩)は2021年入学生(4346±1305歩)より有意に少なかった。また両年共に男性の方が女性より歩数が多く, 月別では4月の歩数が多かった。いずれの年も大学生の至適活動量を大きく下回っていた。以上から新型コロナウイルスによる活動自粛及び授業形態は新入生の歩数に影響を与えていた。

障害等のある学生へ情報保障の方法として音声認識技術の活用が進んでいるが, より有効に活用するためには認識率の担保や運用方法の工夫が必要となる。本稿では, 音声認識技術と補聴システムとを組み合わせた情報保障の質の向上のために, 端末や機器の使用方法を工夫する余地がどの程度あり得るのかについて, 実証実験結果をもとに分析する。実証実験からは, 同じ動画教材でも音量の調節や, 機材の組み合わせにより認識率に差異があることが明らかとなった。一方で, 動画教材の音源の鮮明度等によっては, 技術や機器の使用方法による認識率に大きな開きは見られなかった。このことから, 情報保障機材等の工夫がある程度有効であるものの, 発話や教材作成時の雑音への配慮が必要であると言える。

大学時代にジェネリックスキルを計測した学生の追跡調査によると, 社会人の仕事満足には, 職場からの評価・キャリア自律・自主的な学びが影響している。そこには大学時代の行動持続力・自信創出力との関連が見られる。別の調査では, 地元志向の学生は行動持続力のスコアが有意に低いとの結果が得られた。社会人の仕事満足の観点から, とりわけ地元志向の学生に対して, 行動持続力をはじめとした対自己基礎力を高めるキャリア教育の強化が求められる。

山口大学留学生センターでは, 学部1年生対象の教養コア系列キャリア教育分野科目「知の広場」において「海外留学」に関する講義を行っており, 2021年度は1000名以上が受講した。受講後に学生が作成したコメントをKH Coderで分析し, コロナ禍における学部1年生の海外留学への意識を探った。その結果, 先行研究で留学の阻害要因と指摘されている費用・留年・語学力といった項目について講義で情報を得, さらに海外留学経験者の体験談にふれることで留学の希望を明確にする例や, 留学はしないが国内の身近な環境での国際交流や新たな経験に言及する例など, 1 年生の段階で留学に関する情報提供を行うことの有用性が示唆された。

現在, 通信制課程の高校および生徒は増加傾向にある。1990年代以降, 通信制課程においては, 既存の高校教育の教育システムや教育方針を変える新しい教育の模索が行われている。通信制課程の実態を把握することは, 入学者受け入れを見直す上において重要と考え, 全日制課程との比較から通信制課程の進路選択を把握した。結果, 通信制課程の生徒は, 他者との比較の中で生じる能力アイデンティティの揺らぎや自己意識が高校卒業後の進路希望に影響せず, 大人の勧め等の影響を受けながら「高等学校卒業」という目的に向けて自分が選択した学びを進めているようすが明らかになった。

大学生の地元志向の特徴のひとつである「移ろい」に焦点をあて, 高校生から大学生としての就職活動終了時まで各段階での意識をとらえる。狭い地元志向・広い地元志向・非地元志向の3区分で計測すると, 地方出身学生の約6割は, どこかのタイミングで変化する。就職活動の結果と比較しても, 就活初期段階からは25.5%が, 大学初年次からは36.8%が, なんらかの変化を経験していることがわかった。移ろいがもたらされる要因の解明が課題として残される。
