Badminton is one of the most popular sports in the world and is famous as the sport having the fastest initial velocity of a batted ball among all ball games. Initial velocity immediately after smashing may reach up to 408 km/h (113 m/s) at maximum. A badminton shuttlecock generates significant aerodynamic drag and it was confirmed that the high deceleration characteristics was related to the slots located at the leg portion of a shuttlecock in the previous study. Turnover refers to the flipping experienced by a shuttlecock when undergoing heading change from nose pointing against the flight path at the moment of impact and a shuttlecock indicates the aerodynamically stable feature for the flip movement just after impact. The purpose of this study is to investigate the effect of gaps on the aerodynamic stability (turnover stability) of a badminton shuttlecock during the flip phenomenon. In the present study, the flow field around the shuttlecock during impulsive change of an angle of attack (flip movement) was measured by using the smoke flow visualization and the behavior of the shuttlecock during the flip movement was evaluated in comparison with that of the conic model (with no gaps). The turnover stability of a badminton shuttlecock is affected by gaps of the shuttlecock skirt.

Prostaglandins are a diverse group of eicosanoid hormones that modulate various processes, many of which are related to inflammation. Due to this, prostaglandins are the target of cyclooxygenase (COX) inhibitor drugs. Prostaglandin F2α (PGF2α) mediates processes integral to successful skeletal muscle regeneration, roles elucidated through suppression of its production with various COX-inhibitors. Objective: To provide a comprehensive review of literature regarding roles for the COX-metabolite PGF2α in skeletal muscle regeneration and consequences of its suppression with COX-inhibitors. Design: Systematic review. Method: Recognition was given to early in vitro studies that first established roles for PGF2α in two specific regenerative processes, and attention was then directed to human experiments investigating the PGF2α response to aerobic and resistance exercise. Results: PGF2α mediates protein synthesis and satellite cell activity post-injury. Although methodological differences exist between experiments, research has unanimously demonstrated COX-mediated suppression of PGF2α diminishes these regenerative processes. Conclusions: All experiments in humans have been acute exercise interventions. Studies involving repeated exercise and repeated administration of COX-inhibitors seem warranted to determine if chronic use impedes skeletal muscle regeneration after exercise. Such a finding may hold serious implications for recreational athletes, patients, and clinicians managing musculoskeletal pain or diseases with regular use of COX-inhibitors.

Language is unique to humans and no equivalent cognitive/communication system has been found in other animals, but many similarities have been reported, such as in bird song “syntax” or monkey call “semantics.” Phonology is considered a unique area of the human faculty of language, but recent studies on both monkeys and birds have shown similarities, and further claimed a “new” precursor for the faculty of language. Many linguistic components, including phonology, could be precursors, pre-existing abilities in nonhuman animals, and acquisition of these precursors could act as a pre-adaptation for the emergence of human language.

家族社会学では, 家族を構造 (であるもの) としてではなく, 実践 (するもの・見せるもの) として捉える研究の道筋が切り開かれつつある. 他方で, 家族とは何かという問いを研究者にとっての問題である以前に, 市井の人々自身にとっての問題と捉える研究も登場している. 両者が合流するところに, 人々の立場からその日々のふるまいを検討するという研究課題が生まれる. 会話分析はこの研究課題に取り組む術を提供する. そこで本稿では, 親をすることや親だということを見せることが可能になるしくみのひとつを解明する. そのために本稿は, 母親が同じ場所にいる自分の幼い子どもを「この人」と呼ぶ発言とそれをふくむやりとりを検討する. この呼びかたは, 母親が子どもを子どもとして捉えていないように思えるだろう. だが, 分析の結果, そうではないことが明らかになった. 「この人」は, 近くにいる (「この」) 人物 (「人」) であること以外に, そう呼ばれた人物についていっさいの特徴づけを行わない. それによって, 「この人」はそう呼ばれた人物をめぐる隔たりを刻印する. 母親は, 自分の子どもを「この人」と呼ぶことによって, 普通の子どもとの隔たりを刻印する. あるいはその例外性を際立たせる. 子どもを例外扱いできる人物は, その子どもをよく知っている人物である. 母親は子どもを「この人」と呼ぶことによって, 自分がそんな人物であることを打ち出せる. 子どもを「この人」と呼ぶことは母親としての特権なのである.

Differentiated thyroid carcinoma originates from thyroid follicular cells and is the most prominent malignancy of the endocrine organs. There are two histological types of differentiated carcinoma, namely, papillary and follicular carcinoma. According to reports from Western countries, papillary carcinoma comprises 85.3% of thyroid malignancies in whites, and 72.3% in blacks [1, 2]. In Japan, a previous study showed that the prevalence of papillary carcinoma was 78.4% based on material registered between 1977 and 1986 [3], but according to recent findings reported in 2004 by Japanese Society of Thyroid Surgeons (JSTS), papillary carcinoma accounted for as much as 93% of all thyroid carcinomas. Papillary carcinoma frequently metastasizes to the regional lymph node and shows multicentricity in the thyroid gland. It usually shows a typical ultrasonographic appearance and can be rather easily diagnosed by fine needle aspiration biopsy (FNAB) [4-6]. Follicular carcinoma accounts for 10.9-20.5% of the patients in the United States [1, 2]. In Japan, the prevalence of follicular carcinoma was reported to be 17.2% [3], but it decreased to 5% in a report by JSTS in 2004. This carcinoma is only occasionally diagnosed preoperatively, because it is hard to discriminate follicular carcinoma from benign adenoma on imaging studies and cytologic findings. In contrast to papillary carcinoma, follicular carcinoma more often metastasizes to distant organs than regional lymph nodes. In Japan, the prevalence of papillary carcinoma increased and that of follicular carcinoma decreased between reports from 1977 to 1986 and that in 2004, which may be because follicular variant of papillary carcinoma was classified into follicular carcinoma in the previous results. Generally, these carcinomas show an indolent character, but when the lesion dedifferentiates and becomes undifferentiated carcinoma, it displays very rapid growth with an adverse prognosis and is regarded even as the most aggressive malignancy among human solid carcinomas [7, 8]. Furthermore, cases showing certain characteristics are likely to be constantly progressive and even become life-threatening. Such cases should be regarded as "high-risk" requiring careful and extensive surgical treatment and postoperative follow-up. Indeed, it is most important for physicians to correctly distinguish high-risk cases from those with an indolent character, although how to evaluate the biological characteristics of thyroid carcinoma and how to identify high-risk cases remains highly controversial. In this review, the methods of distinguishing high-risk cases and the appropriate therapeutic strategies for papillary and follicular carcinomas predominantly based on our experience are emphasized and our proposals for therapies including surgical treatment are demonstrated.

The African primate fossil record is very poor between the mid-Middle and mid-Late Miocene. Nakali (~10–9.8 Ma) is one of the rare African localities that have yielded primate fossils from this period, including a new genus of great ape, Nakalipithecus nakayamai, and another large-bodied hominoid species. The Nakali primate fauna also includes small-bodied ‘apes’ and Old World monkeys (mostly colobines). In this article, we describe a new specimen of a small-bodied ‘ape’ discovered from Nakali, which is assigned to nyanzapithecines. Nyanzapithecines are characterized by their derived dental morphology, and the previously known nyanzapithecines range in chronological age between the Late Oligocene and early Middle Miocene (~25–13.7 Ma). The new nyanzapithecine specimen from Nakali is therefore the latest occurrence of this group in the African fossil record, extending its chronological range by almost 4 million years younger.

Aim: Increased epicardial fat volume (EFV) is an independent risk factor for acute coronary syndrome (ACS). Although EFV increases with body mass index (BMI), some ACS patients have an increased EFV but normal BMI. We here investigated the clinical characteristics of nonobese ACS patients with an increased EFV.Methods: A total of 197 Japanese patients hospitalized for ACS was evaluated for EFV, abdominal visceral fat area (VFA), and lipid and glucose profiles. Control subjects comprised 141 individuals who were suspected of having ACS but whose coronary computed tomography findings were normal.Results: EFV was increased in ACS patients compared with control subjects (120±47 versus 95±45 mL, P<0.01). ACS patients were divided into four groups based on average EFV (120 mL) and a BMI obesity cutoff of 25 kg/m2. For the 30 nonobese ACS patients with an above-average EFV, EFV was positively correlated with VFA (r=0.23, P=0.031). These individuals were significantly older (74±10 years) and tended to have a higher homeostasis model assessment–insulin resistance value (5.5±3.8) compared with other ACS patients. Among nonobese study subjects, EFV was independently associated with ACS (odds ratio=2.01, P=0.021) and correlated with abdominal circumference (r=0.26, P=0.017).Conclusion: Nonobese ACS patients with an increased EFV were elderly and tended to manifest insulin resistance. Measurement of EFV may prove informative for evaluation of ACS risk among elderly nonobese individuals with an increased abdominal girth.

An intense rainband associated with Typhoon 1326 (Wipha) induced a fatal debris flow on Izu Oshima, Japan, on October 15-16, 2013. This rainband formed along a local front between the southeasterly humid warm air around the typhoon and the northeasterly cold air from the Kanto Plain. In this paper, the Japan Meteorological Agency Nonhydrostatic Model was optimized for the “K computer,” and ultra-high-resolution (500-250 m grid spacing) numerical simulations of the rainband with a large domain were conducted. Two of main factors that affect a numerical weather prediction (NWP) model, (1) grid spacing and (2) planetary boundary layer (PBL) schemes [Mellor–Yamada–Nakanishi–Niino (MYNN) and Deardorff (DD)], were investigated. Experiments with DD (Exps_DD: grid spacings of 2 km, 500 m, and 250 m) showed better reproducibility of the rainband position than experiments with MYNN (Exps_MYNN: grid spacings of 5 km, 2 km, and 500 m). Exps_DD simulated distinct convective-scale up/downdraft pairs on the southeast/northwest sides of the front, whereas those of Exps_MYNN were not clear. Exps_DD yielded stronger cold pools near the surface than did Exps_MYNN. These differences in the boundary layer structures likely had a large impact on the position of the front and the associated rainband. Exps_DD with the 500-m grid spacing showed the best precipitation performance according to the Fractions Skill Score. To check other factors of the precipitation forecast, model domain sizes, lateral boundary conditions in nesting simulations, and terrain representations were investigated. In the small domain experiments, the rainband shapes were very different from the observations. In the experiment using a nesting procedure, the deterioration of the forecast performance was acceptably reduced. The model with fine terrains better reproduced the intense rain over the island. These results demonstrate that the ultra-high-resolution NWP model with a large domain has the possibility to improve predictions of heavy rain.

Radiological technologists (RTs) and medical technologists (MTs) are legally allowed to work as sonographers performing medical ultrasound examination. Despite the total number, much fewer RTs work as sonographers than MTs. To explore the reason, we investigated educational programs, universities, and colleges for both specialties. First, we established five categories of sonographers’ competency: 1) Anatomy for imaging diagnosis, 2) Diseases and diagnosis, 3) Imaging, 4) Structure and principle of the equipment, and 5) Evaluation of image quality, using competence reported by the International Society of Radiographers and Radiological Technologists (ISRRT) and diagnostic competency required of sonographers in Japan. Using these categories, we analyzed the content and total instruction time by lectures and seminars based on information written in the syllabi, and explored the differences in education related to sonographers’ competency in both programs. “Anatomy for imaging diagnosis” was taught in 15 RT programs (93.8%), and 6 MT programs (31.6%). “Diseases and diagnosis” was taught in 13 RT programs (86.7%), and 8 MT programs (53.3%). “Imaging” was taught in 14 RT programs (100%), and 13 MT programs (76.5%). “Structure and principle of the equipment” was taught in 12 RT programs (85.7%), and 6 MT programs (31.6%). “Evaluation of image quality” was taught in 11 RT programs (84.6%), and 3 MT programs (15.0%). The average instruction time for RT was longer than for MT programs in all categories. RTs are educated and have a foundation to be sonographers at graduation, and may have the possibility to expand their career in this field.
