<P>The degree of ferromagnetism of Ni-W<SUB>y</SUB> alloys decreases as W-content y increases. Both the saturation magnetization <I>M</I> <SUB>sat</SUB> and Curie temperature <I>T</I> <SUB>c</SUB> decrease linearly with W-content y, and both <I>M</I> <SUB>sat</SUB> and <I>T</I> <SUB>c</SUB> go to zero at critical concentration of y<SUB>c</SUB> ~9.50 at.% W. To compare with Ni-W alloys, the magnetic properties of a series of both as-rolled (non-textured) and annealed (biaxially textured) [Ni<SUB>97at.%</SUB>-W<SUB>3at.%</SUB>]<SUB>100-x</SUB>-Cu<SUB>x</SUB> alloy tapes with compositions x = 0, 1, 3, 5, and 7 at.%, were studied. Characterization methods included XRD analyses to investigate the biaxial texturing of the annealed [Ni-W]-Cu alloy tapes and studies of the magnetization for both as-rolled and annealed [Ni-W]-Cu alloy tapes. Both the isothermal mass magnetizations <I>M</I>(<I>H</I>) of a series of samples at different fixed temperatures and <I>M</I>(<I>T</I>) in fixed field, were measured. The effect of Cu addition on both the saturation magnetization and Curie temperature T<SUB>c</SUB> of the Ni<SUB>97at.%</SUB>-W<SUB>3at.%</SUB> alloy was investigated.</P>

A vehicle dynamic analysis program AutoDyn7 (Automobile Dynamics in G7) is developed during the G7 project with respect to "development of integrated software for the chassis system design and analysis"<br/> In this paper, computer simulations of the selected vehicle maneuver are performed using AutoDyn7 S/W. Simulation results are compared with the results of driving tests with experimental handling vehicle for validation and evaluation of the developed S/W AutoDyn7. It is expected that the vehicle dynamic analysis program AutoDyn7 is effectively applicable to design and analysis the chassis system in the early design stage of vehicle development.<br/>

We computed the % Fat by the measured values of skinfold thickness at 4 sites; back, waist, abdomen, arm with 20 male gymnasic players(8 Kyung Hee high school, 12 Kyung ung Hee university players) and with 16 Female gymnastic player (8 Kyung He girl’s high school players, 8 Kyung Hee university players) hat all (total) 36 players were executed.Calculation Formula● high school players% Fat=1.324×Mean Skinfold thickness(mm) -0.045● Male College players% Fat=0.911×Mean Skinfold thickness(㎜)+8.1● Female high school and college players% Fat=0.58×Mean skinfold thickness(㎜)+14.311. The player’s average Skinfold thickness of 4 sites was less that of non-athletic persons.2. Both of male and Female gymnastic players showed the maximum value on the among 4 sites, while non-athltic males showed in back and Female in Arms, the maximum value.3. The Female player’s Skinfold thickness was thicker than that of male about 5.8㎜.4. The Kyung Hee high school gymnastic players skinfold thickness is as follws;back 6.9㎜waist 8.3㎜abdomen 5.9㎜arm 4.8㎜, the skinfold thickness averaged 6.3㎜and the Kyung Hee university gymnastic player’sSkinfold thickness is as follows;back 6.5㎜waist 8.9㎜abdomen 5.8㎜arm 4.7㎜, the Skinfold thickness averaged 6.4㎜5. The Kyung Hee girl’s High school player’s skinfold thickness is as follows;back 9.6㎜waist 12.1㎜abdomen 11.9㎜arm 8.3㎜, the Skinfold thickness averaged 10.1㎜ and the women’s skinfold thikness(Kyung Hee university gymnastic players) is as follows;back 10.8㎜waist 16.7㎜abdomen 11.0㎜arm 11.3㎜, the skinfold thickness averaged 12.4㎜6. The male players % Fat 11.7% (High school players 8.3%, college players 14.0%) and Female player’s % Fat was 2.8% (girl’s High school player’s 20.1%, colleye players 21.5%)7. Both of male and Female gymnastic player’s % Fat was less that of non-athletic persons and college player’s % Fat was more than that of high school players.
S6K1 Phosphorylation of H2B Mediates EZH2 Trimethylation of H3: A Determinant of Early Adipogenesis
Yi, S.,Um, S.,Lee, J.,Yoo, J.,Bang, S.,Park, E.,Lee, M.,Nam, K.,Jeon, Y.,Park, J.,You, J.,Lee, S.J.,Bae, G.U.,Rhie, J.,Kozma, Sara C.,Thomas, G.,Han, J.W. Cell Press 2016 Molecular Cell Vol.62 No.3
S6K1 has been implicated in a number of key metabolic responses, which contribute to obesity. Critical among these is the control of a transcriptional program required for the commitment of mesenchymal stem cells to the adipocytic lineage. However, in contrast to its role in the cytosol, the functions and targets of nuclear S6K1 are unknown. Here, we show that adipogenic stimuli trigger nuclear translocation of S6K1, leading to H2BS36 phosphorylation and recruitment of EZH2 to H3, which mediates H3K27 trimethylation. This blocks Wnt gene expression, inducing the upregulation of PPARγ and Cebpa and driving increased adipogenesis. Consistent with this finding, white adipose tissue from S6K1-deficient mice exhibits no detectable H2BS36 phosphorylation or H3K27 trimethylation, whereas both responses are highly elevated in obese humans or in mice fed a high-fat diet. These findings define an S6K1-dependent mechanism in early adipogenesis, contributing to the promotion of obesity.
