Life-long integrated sports

行政機関による生涯スポーツの推進は、それなりに容認されよう。しかしながら、国民のすべてが、こぞってそれに応えているとしたら、異常である。元来、スポーツは、国民の一人ひとりが、気ままに営むべきものである。それを、スポーツ振興法等に名を借りて、スポーツの機会や条件を提供し、また、国民の健康や体力の増強に与って効力があるからといって、国や地方公共団体の管理に供するということへの、懸念が生じてくる。さらに、関係団体との接触についても懸念がある。巷間、伝わるところの”モスクワ五輪大会への干渉”である。具体的に知る由もないが、結論に至までの過程に重要な要素が含まれていたように思われる。今後も、生涯スポーツの関係団体等に対して、これと類似したケースが生じないとは限らない。公権力の介入も、充分に予想し得る。以下に、生涯スポーツ事業の系譜を纏め、対応への資料として、提供する。The promotion of life-long integrated sports by goverment administration may be acceptable, However, it would be unusual if all citizens accepted this policy by the goverment. Essentially, sports should be played, by the independent will of each person. State and local goverments, may offer people the opportunity and conditions, under the sports Promotion Law, to play sports. Their reason for encouraging people to play sports is obviously because it promotes health and physical fitness. However, this policy may also create the fear that the authorities will control people. I am also anxious about contact between Japanese sports organizations and the goverment. To cite an example, the Japanese goverment interfered, and was, I believe, responsible for the non-participation of Japanese representatives as the Moscow Olympics. I am sure that this decision was affected by the goverment. We cannot guarantee that similar situations involving various sports group. It is possible that this sort of thing will occur again ; that the authorities will intervene in sporting activities. I would like to offer an organization chart regarding life-long integrated sports as follows ; (1) Beginning-after the war. (2) An origin. (3) Adult education. (4) Pre-Olympic-games. (5) Post-Olympic-games

On Club Activity in School -Especially Those Related with the Tokubetsu Katsudo-

Judzing from this, club activities must be included not in school education but in adult education. And so club activities in school must be practiced from the point of adult education. It seems, however, that the accepter has not been prepard yet. For the reason, It is impossible to exclude club activities at once from school education. From this point, the system of life-long education must be made up promptly and club activities are preferable to be separated from school education. On both sides of school education and adult education, the administrative readjustment must be excuted first of all for the activities of school clubs being pushed forward. It seems, however, that the problems are in Shido-yoryo itself: especially how to deal with Tokubetsu-katsudo is the problem. In other words, Shido-yoryo says, "Tokubetsu-katsudo must be separated from adult education" or "It is not practiced necessarily in adult education" in one time and "It has been applied corresponding to Bukatsu instead of Kurabu" in another time. Shido-yoryo has influenced greatly on the activities in school education

Factors involved in the movement of the center of mass in healthy women

妊娠中の体形変化は姿勢変化をもたらし、このためにおこる重心移動がマイナートラブルを起こす原因となることが考えられる。そこで、健康女性37人を対象に、重心動揺を起こす因子と考えられる体型要因に着目した基礎的研究を行い、以下の結果を得た。1）重心動揺測定項目の中で、重心動揺距離、包絡面積、重心動揺面積の項目は開眼時より閉眼時が有意に数値が大きく、X軸方向動揺平均、Y軸方向動揺平均の項目は、開眼時と閉眼時とで差がなかった。2）ロンベルグ姿勢での開眼及び閉眼重心動揺検査では、座高、下肢長に正の相関が、肥満度に負の相関があるこが示唆された。During the period of pregnancy, movement of the center of mass due to changes in the posture results from the changes in the body form, and this may cause minor troubles. In this study, we examined body form factors which may be involved in the movement of the center of mass in 37 healthy womem, and obtained the following results. 1) In the examination items of the movement of the center of mass, the moving distance of the center of mass, the envelope area and the area of moving of the center of mass were significantly larger when measured with the eyes open than when measured with the eyes closed, while there were no differences in the means of moving in the x-axis direction and in the y-axis direction whether the eyes were open or closed. 2) The moving examinations of the center of mass in the Romberg's posture with open or closed eyes suggested positive correlations with the sitting height and the length of the inferir limb and a negative correlation with the obesity level

PARP6 acts as a tumor suppressor via downregulating Survivin expression in colorectal cancer

Poly (ADP-ribose) polymerases (PARPs) are enzymes that transfer ADP-ribose groups to target proteins and are involved in a variety of biological processes. PARP6 is a novel member, and our previous findings suggest that PARP6 may act as a tumor suppressor via suppressing cell cycle progression. However, it is still unclear that PARP6 function besides growth suppression in colorectal cancer (CRC). In this study, we examined tumor suppressive roles of PAPR6 in CRC cells both in vitro and in vivo. We found that PARP6 inhibited colony formation, invasion and migration as well as cell proliferation. Moreover, ectopic overexpression of PARP6 decreased Survivin expression, which acts as an oncogene and is involved in apoptosis and mitosis. We confirmed the inverse correlation between PARP6 and Survivin expression in CRC cases by immunohistochemistry. Importantly, CRC cases with downregulation of PARP6 and upregulation of Survivin showed poor prognosis. In summary, PARP6 acts as a tumor suppressor via downregulating Survivin expression in CRC. PARP6 can be a novel diagnostic and therapeutic target together with Survivin for CRC

Optical Properties of (162173) 1999 JU3: In Preparation for the JAXA Hayabusa 2 Sample Return Mission

We investigated the magnitude-phase relation of (162173) 1999 JU3, a target asteroid for the JAXA Hayabusa 2 sample return mission. We initially employed the international Astronomical Union's H-G formalism but found that it fits less well using a single set of parameters. To improve the inadequate fit, we employed two photometric functions, the Shevchenko and Hapke functions. With the Shevchenko function, we found that the magnitude-phase relation exhibits linear behavior in a wide phase angle range (alpha = 5-75 deg) and shows weak nonlinear opposition brightening at alpha< 5 deg, providing a more reliable absolute magnitude of Hv = 19.25 +- 0.03. The phase slope (0.039 +- 0.001 mag/deg) and opposition effect amplitude (parameterized by the ratio of intensity at alpha=0.3 deg to that at alpha=5 deg, I(0.3)/I(5)=1.31+-0.05) are consistent with those of typical C-type asteroids. We also attempted to determine the parameters for the Hapke model, which are applicable for constructing the surface reflectance map with the Hayabusa 2 onboard cameras. Although we could not constrain the full set of Hapke parameters, we obtained possible values, w=0.041, g=-0.38, B0=1.43, and h=0.050, assuming a surface roughness parameter theta=20 deg. By combining our photometric study with a thermal model of the asteroid (Mueller et al. in preparation), we obtained a geometric albedo of pv = 0.047 +- 0.003, phase integral q = 0.32 +- 0.03, and Bond albedo AB = 0.014 +- 0.002, which are commensurate with the values for common C-type asteroids.Comment: 27 pages, 4 figure, accepted for publication in the Astrophysical Journa

Spectroscopic Mass and Host-star Metallicity Measurements for Newly Discovered Microlensing Planet OGLE-2018-BLG-0740Lb

We report the discovery of the microlensing planet OGLE-2018-BLG-0740Lb. The planet is detected with a very strong signal of $\Delta\chi^2\sim 4630$, but the interpretation of the signal suffers from two types of degeneracies. One type is caused by the previously known close/wide degeneracy, and the other is caused by an ambiguity between two solutions, in which one solution requires to incorporate finite-source effects, while the other solution is consistent with a point-source interpretation. Although difficult to be firmly resolved based on only the photometric data, the degeneracy is resolved in strong favor of the point-source solution with the additional external information obtained from astrometric and spectroscopic observations. The small astrometric offset between the source and baseline object supports that the blend is the lens and this interpretation is further secured by the consistency of the spectroscopic distance estimate of the blend with the lensing parameters of the point-source solution. The estimated mass of the host is $1.0\pm 0.1~M_\odot$ and the mass of the planet is $4.5\pm 0.6~M_{\rm J}$ (close solution) or $4.8\pm 0.6~M_{\rm J}$ (wide solution) and the lens is located at a distance of $3.2\pm 0.5$~kpc. The bright nature of the lens, with $I\sim 17.1$ ($V\sim 18.2$), combined with its dominance of the observed flux suggest that radial-velocity (RV) follow-up observations of the lens can be done using high-resolution spectrometers mounted on large telescopes, e.g., VLT/ESPRESSO, and this can potentially not only measure the period and eccentricity of the planet but also probe for close-in planets. We estimate that the expected RV amplitude would be $\sim 60\sin i ~{\rm m~s}^{-1}$.Comment: 12 pages, 11 figures, 4 table

Candidate Brown-dwarf Microlensing Events with Very Short Timescales and Small Angular Einstein Radii

Short-timescale microlensing events are likely to be produced by substellar brown dwarfs (BDs), but it is difficult to securely identify BD lenses based on only event timescales t_E because short-timescale events can also be produced by stellar lenses with high relative lens-source proper motions. In this paper, we report three strong candidate BD-lens events found from the search for lensing events not only with short timescales (t_E ≲ 6 days) but also with very small angular Einstein radii (θ_E ≲ 0.05 mas) among the events that have been found in the 2016–2019 observing seasons. These events include MOA-2017-BLG-147, MOA-2017-BLG-241, and MOA-2019-BLG-256, in which the first two events are produced by single lenses and the last event is produced by a binary lens. From the Monte Carlo simulations of Galactic events conducted with the combined t_E and θ_E constraint, it is estimated that the lens masses of the individual events are 0.051^(+0.100)_(−0.027) M⊙, 0.044^(+0.090)_(−0.023) M⊙, and 0.046^(+0.067)_(−0.023) M⊙/0.038^(+0.056)_(−0.019) M⊙ and the probability of the lens mass smaller than the lower limit of stars is ~80% for all events. We point out that routine lens mass measurements of short-timescale lensing events require survey-mode space-based observations
