As a measure to prevent the spread of COVID-19, telecommuting has been recommended by many companies since March 2020 in Japan. Even after the COVID-19 pandemic is over, the telecommuting implementation rate, including working from home, may continue to increase.The purpose of this study is to clarify the impact of working from home on the individual satisfaction and productivity of workers in companies that introduced the telecommuting system from April 2020 as a countermeasure against COVID-19.Questionnaire surveys of workers who normally work at an activity-based working office were conducted in order to compare the effects of working from home and at the office. The survey targets were workers of a research and development institute located in Chiba Prefecture, Japan. Approximately 210 employees work in the facility, of which 85% are researchers and 15% are in clerical positions. In this study, the results of three questionnaire surveys are described. We conducted a survey of “conventional office work period” in February 2020, a survey of “recommended work from home period” in April 2020, and a survey of “combined work from home and at the office period” in July 2020 where workers could choose to go to work or work from home.From the survey results, it was found that the working environment at home had large individual differences, and the illuminance and CO2 concentration levels often deviated from the standards of the “Ordinance on Health Standards in the Office”. Despite the environment with large differences, the satisfaction level of the thermal environment, air quality and sound was significantly higher at home. It was also found that when working from home, self-efficacy regarding control of the indoor environment increases. This is considered to be one of the reasons for the increase in satisfaction of environmental qualities at home.As an advantage of working from home, most office workers chose “reduction of coronavirus infection risk”. Next, more than half of the respondents chose “having no commuting stress” and “having a reduced dress code” as advantages. On the other hand, “lack of face-to-face communication” became the highest disadvantage of working from home. The degree of satisfaction with interpersonal communication was significantly lower at home than at work. In particular, the decrease in the satisfaction of informal communication was large.Compared to the period when workers could only work at the office or at home, the period with relative freedom to choose between both options showed a great increase in the satisfaction with the work environment and a decrease in the difficulty of performing office activities.In addition, a high correlation was found between the frequency of working from home and commuting time. Workers with longer commuting hours tended to work at home more frequently. Furthermore, it was confirmed that the higher the frequency of working from home, the higher the degree of satisfaction with the working environment at home.The most common response to the ideal rate of working from home was two times a week, but the actual rate was only 25% in the survey conducted in July. It is presumed that there were many situations in which employees chose to come to the office in order to proceed with their work duties more efficiently.

企業の情報システムを構成するOSやハードウェアの更改に対して,それら環境の上で動作するソフトウェアの回帰検査技術を確立することが,急務となっている.特に近年は,技術の加速的な進歩によって,EOL(End Of Life)までの期間が短縮化している.それによって,ソフトウェアの動作環境の更改頻度が増加しているため,回帰検査の稼働を低減することが重要な課題である.この課題を解決するために,本研究ではGUIを持つソフトウェアを対象として,GUIアクセシビリティ技術により網羅的に自動操作し,更改前後の画面遷移を比較することで,画面遷移の回帰検査を自動化する.提案手法は,動作するソフトウェアさえあれば,画面遷移の網羅的な回帰検査が可能であるという特長がある.ソフトウェアの動作環境の更改にともなう回帰検査の現場では,検査期間,体制,開発成果物の管理状況などによって,たとえば,テストケース設計などを適切に行えない場合が数多くある.提案手法は,このような状況下にあるときの検査品質の向上にも貢献できる.本発表では,網羅的に自動操作するアルゴリズムと,提案手法を適用したときの実験結果を報告する.The one of important issues in many information departments is the regression checking of software for change of operating systems and hardware on which software run in information systems. The life of operating systems and hardware gets shorter because of the rapid progress of these techniques. Therefore information departments often must renew such environments in information systems and check whether same software run on new environments immutably. For information departments, reducing costs for the regression checking is a big challenge. To accomplish this goal, we propose the automation technique for the regression checking of screen transitions in software with the graphical user interface (GUI). In our method, we operate the GUI of software exhaustively using GUI accessibility techniques and compare obtained screen transitions between old environments and new ones. The feature of our method is that it enables us to check exhaustively with only running software. The many fields of such the regression checking usually cannot design test cases faithfully by several factors, for example the lack of testing time and the knowledge of test techniques, sloppy managements of development deliverables and so on. Our technique can check screen transitions thoroughly in such conditions. In this presentation, we report our automatic operation algorithm and experimental results.

The tribological properties of silicon with and without water boundary lubrication with silicon, silicon carbide and a diamond tip were studied and the following results were obtained. (1) The friction coefficient between silicon and silicon or silicon carbide tips is as high as μ=0.2〜1.0, with and without lubrication. Surface damage occurred due to the adhesion between similar materials. (2) When a diamond is used as the opposite tip, the friction coefficient is as low as μ=0.09〜0.16 without lubrication. With water boundary lubrication, the friction coefficient is as low as μ=0.07. Damage is not observed on surfaces either with or without water boundary lubrication. (3) To determine the reason why sliding with the diamond tip did not result in damage, stress analysis was carried out using the boundary element method for each combination of materials. The maximum Mises stress was observed inside the silicon and diamond bulk when silicon and diamond were tested. However, the maximum Mises stress for the silicon with silicon and silicon carbide with silicon combination was observed.

Objectives: The purpose of this study was to investigate the incidence of multiple chemical sensitivity (MCS) and effectiveness of the Quick Environment Exposure and Sensitivity Inventory (QEESI) in Japanese workers in specific buildings. Methods: The survey was performed in 2004–2006 in Japan. QEESI (Japanese version) and a checklist on accumulation of fatigue developed by the Ministry of Health, Labour and Welfare were used in the examination of 410 workers in specific buildings. Three criteria of QEESI’s “symptom severity”, “chemical intolerance”, and “other intolerance” were evaluated in this study. Clinical histories were also surveyed. Result: Responses were obtained from 368 (89.8%) workers. The results showed that 132 (35.9%) individuals have been diagnosed as having allergy. Only two (0.5%) individuals were found to be MCS patients. There was no sick building syndrome patient. Applying the “high” criteria with QEESI to the standard of Miller and Ashford, we determined that only four (1.1%) individuals met all the three criteria, and 17 (4.6%) individuals met two of the three criteria. The QEESI score of allergy persons was higher than that of nonallergy persons. Among nonallergy persons, those who have a high score on accumulation of fatigue in the checklist showed a high score in QESSI. Conclusions: These findings indicated that the QEESI score tended to increase with workload and be high in individuals with allergy. Therefore, careful consideration is required, when QEESI is applied for screening MCS patients in Japan.
