In our previous work we proposed two approaches to singularity treatment: one is based on a null space notation, and the other on an adjoint Jacobian. We call these approaches as the singularity-consistent approach. Both meth-ods guarantee the direction of motion in the whole work space, without producing an infeasible joint velocity. The performance has been experimentally verified with 3-DOF manipulators. In this paper, we apply the method to a real telerobot system with a non-redundant 6-DOF manipulator as the slave. We analyze the velocity relation at the singularities of this manipulator, and discuss several important implementation issues. The experimental results show that the 6-DOF manipulator can be operated safely with feasible joint velocity and without any error in the direction of motion.

Iatrogenic ureteral injury (IUI) is a dreaded complication of abdominopelvic surgery. Although rare, it is associated with severe consequences. This complication most commonly occurs during gynecological procedures but may also occur during colorectal surgeries. We present two cases of IUI in patients in whom the ureteric stents were electively placed. The first case was a 71-year-old male with no significant medical history. The patient underwent an elective laparoscopic sigmoidectomy for complicated diverticulitis. During the procedure, a proximal IUI occurred, and was recognized and repaired. The second case occurred in a 68-year-old male with a history of multiple complicated abdominal surgeries. The patient underwent a second redo low anterior resection for a long preanastomotic stricture. The IUI occurred in the right fibrosed presacral plane, approximately 3 cm proximal to the bladder. The ureter was reimplanted to the bladder during the same procedure. We will also present a literature review of IUI, including the risk factors, intraoperative prevention, and repair options.

Large-amplitude meteotsunamis were observed in many areas in Japan, following the arrival of barometric Lamb waves emitted by an underwater volcanic eruption of Hunga Tonga-Hunga Ha‘apai in January 2022. We modeled the power spectra of the tidal level data obtained from 12 tide stations of the Geospatial Information Authority of Japan, based on a method of transfer function which converts the barometric pressure pulse spectra into the meteotsunami spectra. The obtained transfer functions are similar at 12 stations. The pressure pulse spectra are obtained from the ensemble average of ∼1500 Soratena weather sensors of Weathernews Inc. distributed over Japan. The observed meteotsunami spectra can be characterized by the enhanced seiche eigenmodes at each station excited by the mesoscale pressure pulse within the amplitude error of 50%, which contributes for accumulating the necessary knowledge to understand the potential dangers in various different areas over Japan.

This study set out to compare structural and invasive characteristics of sporadic papillary thyroid carcinoma (PTC) in age-matched groups of children and adolescents of Japan and Ukraine to provide detailed histopathological analysis of tumors from different geographical areas with different iodine intake. A total of 348 (160 Japanese and 188 Ukrainian) PTCs from patients without radiation history were analyzed initially as a combined pediatric group and then subdivided into childhood (aged ≤14 years) and adolescent (aged from 15 to ≤18 years) age series. On multivariate comparison, the Japanese pediatric PTC was characterized by a higher sex ratio (p=1.504E-4), and a higher frequency of microcarcinoma (p=0.039), papillary dominant growth pattern (p=0.024), focal oxyphilic cell metaplasia (p=7.644E-6), intrathyroid spread (p=0.010), lymphatic/vascular invasion (p=0.01) and regional lymph node metastases (p=3.540E-6). In the Ukrainian group, multifocal (p=0.004) and non-encapsulated tumors with the solid-trabecular growth pattern (p=0.05) were more frequent. Childhood Japanese PTCs differed from Ukrainian PTCs by more pronounced invasive properties such as lymphatic/vascular invasion and nodal disease, but did not differ by the dominant growth pattern. In adolescents, the differences were detected not only for lymph node metastases, but also for a higher frequency of the papillary dominant pattern in Japanese PTC. Overall, significantly higher frequencies of oxyphilic cell metaplasia and more pronounced invasive features observed in the Japanese PTC in both age-matched series represent the major differences between the tumors from two geographical areas.

The assessment of energy cost (EC) at the workplace remains a key topic in occupational health due to the ever-increasing prevalence of work-related issues. This review provides a detailed list of EC estimations in jobs/tasks included in tourism, agriculture, construction, manufacturing, and transportation industries. A total of 61 studies evaluated the EC of 1667 workers while performing a large number of tasks related to each one of the aforementioned five industries. Agriculture includes the most energy-demanding jobs (males: 6.0 ± 2.5 kcal/min; females: 2.9 ± 1.0 kcal/min). Jobs in the construction industry were the 2nd most demanding (males: 4.9 ± 1.6 kcal/min; no data for females). The industry with the 3rd highest EC estimate was manufacturing (males: 3.8 ± 1.1 kcal/min; females: 3.0 ± 1.3 kcal/min). Transportation presented relatively moderate EC estimates (males: 3.1 ± 1.0 kcal/min; no data for females). Tourism jobs demonstrated the lowest EC values (2.5 ± 0.9 kcal/min for males and females). It is hoped that this information will aid the development of future instruments and guidelines aiming to protect workers’ health, safety, and productivity. Future research should provide updated EC estimates within a wide spectrum of occupational settings taking into account the sex, age, and physiological characteristics of the workers as well as the individual characteristics of each workplace.

Leisure-time physical activity (LTPA) and dietary energy intake are two important health behaviours, which at too low or high levels respectively, are associated with overweight and obesity. This study explores associations between subscales of the Job Demand-Control-Support (JDCS) model, LTPA and dietary energy intake. A cross-sectional design sampled current employees (N=433) from a South Australian cohort using a computer-assisted telephone interview and a self-completed food frequency questionnaire. In analyses adjusted for sex, age, and sociodemographic variables, higher levels of skill discretion were associated with increased odds for attaining sufficient physical activity (OR=2.45; 95% CI=1.10–5.47). Higher levels of decision authority were associated with reduced odds (OR=0.43; 95% CI=0.20–0.93) for being in the highest tertile of daily energy intake. Higher scores for coworker support were associated with increased odds (OR=2.20; 95% CI=1.15–4.23) for being in the highest tertile of daily energy intake. These findings support the consideration of the individual JDCS subscales, since this practice may reveal novel associations with health behaviour outcomes, thereby presenting new opportunities to improve employee health and wellbeing.

[Purpose] In this study, we sought to evaluate the relationship between the Barthel Index and the Mini Nutritional Assessment Short Form in a cohort of elderly patients hospitalized in the General Rehabilitation Center. [Subjects and Methods] Three hundred and forty-four patients underwent an extensive evaluation, which included the following tests: 1) a Mini Nutritional Assessment Short Form to evaluate nutritional status; and 2) a Barthel Index assessment to evaluate functional status. We categorized patients into three age groups (65–74 yrs, 75–84 yrs, and >85 yrs). Barthel Index cutoff scores were defined as ≥45 out of 100 for better functional status and <45 for worse functional status. [Results] Significant associations between age distribution and the scores obtained with the Barthel Index and Mini Nutritional Assessment Short Form were found; nutritional status measured with Mini Nutritional Assessment Short Form and functional status measured with the Barthel Index were positively related. [Conclusion] This study shows that the Mini Nutritional Assessment Short Form value was associated with the Barthel Index score, and that these scores varied with age.

Objectives: This study investigated the performance enhancing effects of bicarbonate ingestion on soccer specific perfor mance. Design: A randomized and double-blinded study. Methods: Division III collegiate male soccer players (N = 7) participated in the study. Participants ingested either an alkaline treatment (.3 g/kg NaHCO3) or placebo (cornflower) 60 min prior to exercise on two separate testing sessions spaced 7 days apart. Distance to fatigue in the Yo-Yo Intermittent Recovery Test Level 2 was used to assess performance. Capillary blood was sampled pre-ingestion (PE), 60 min post ingestion (PI), exhaustion (EX), following 15 min of recovery (RC) and analyzed for lactate ([La–]) and pH. Results: No significant ( p > .05) differences between conditions existed for performance. A significant ( p < .05) main effect was found for [La–]: values at EX were significantly greater than PE, PI, and RC; however, no interaction ( p > .05) existed between time and condition. pH values at PE and PI were significantly greater than EX and RC in both conditions; however, pH was significantly ( p < .05) greater at PI than PE in treatment but not placebo. Conclusion: Bicarbonate ingestion increased extracellular buffering capacity but does not appear to enhance shuttle run per formance in Division III soccer players. mance.

Few medical journals specifically instruct authors to use the active voice and avoid the passive voice, but advice to that effect is common in the large number of stylebooks and blogs aimed at medical and scientific writers. Such advice typically revolves around arguments that the passive voice is less clear, less direct, and less concise than the active voice, that it conceals the identity of the person(s) performing the action(s) described, that it obscures meaning, that it is pompous, and that the high rate of passive-voice usage in scientific writing is a result of conformity to an established and old-fashioned style of writing. Some of these arguments are valid with respect to specific examples of passive-voice misuse by some medical (and other) writers, but as arguments for avoiding passive-voice use in general, they are seriously flawed. In addition, many of the examples that stylebook writers give of inappropriate use are actually much more appropriate in certain contexts than the active-voice alternatives they provide. In this review, I examine the advice offered by anti-passive writers, along with some of their examples of “inappropriate” use, and argue that the key factor in voice selection is sentence word order as determined by the natural tendency in English for the topic of discourse (“old” information) to take subject position and for “new” information to come later. Authors who submit to this natural tendency will not have to worry much about voice selection, because it will usually be automatic.

地球意識計画(GCP)と呼ばれる長期継続実験は、同期的に生成されたランダムデータの流れの中から、大規模な出来事によって生じるランダムでない構造を探索する。地球規模の乱数発生器(RNG)ネットワークが、最多で世界65箇所の並列ランダムデータの系列を記録し、「世界的な出来事(素晴らしい祝典や悲劇に対する広範囲の精神的・感情的な一時的反応と定義)」が起こっているときに期待値からデータが偏るという仮説を厳密な実験で検証する。現在進行中の再現実験は、指定された出来事の期間、ネットワーク中の相互作用を測定する。そして過去15年以上にわたる450件以上の公式仮説の結果は十分に期待値から離れており、帰無仮説に対して1兆分の1以下である。対照実験によって従来の物理学的説明や実験エラーは除外され、また実験計画法によって解釈が制限される。実験結果は、ある種の人間の意識が効果の源として含まれていることを示唆している。ランダムデータの微かな構造化は、人間の可干渉な注目と感情が物質世界に効果をもたらすことを示している。

Road lighting is best known to have the potential to improve night-time safety. The vast majority of research studies have shown that the installation of road lighting has favourable effects on the number and severity of road collisions. In addition, some evidence suggests that current road lighting practices are over-lighting the roadway. Therefore, the rapidly growing concerns about energy consumption and its related costs will force further changes in road lighting technology and practice. To date, there have been no studies that investigated the association between current knowledge and the road lighting guidelines. This article reviews and discusses CIE road lighting guidelines for motorised traffic. It then provides current knowledge in the area of lighting motorised roads leading to possibilities for intelligent lighting control. Finally, suggestions for considering dimming of road lighting based on recent developments in science and technology are provided. The three recommended approaches, static road lighting, semi-dynamic lighting levels, and dynamic lighting levels, could save energy without compromising traffic safety.
