  • This study was divised to observe the effects of defatted(by petroleum ether) Korean ginseng on the cholesterol level of Sprague-Dowley Albino male rats by alternating the diet. 130 heads of weaned rats having 83$\pm$4g of body weight were fed with each stock diets supplemented with 0.5, 1.0 and 3.0% defatted ginseng powder for 4 or 8 weeks, and after that fed with stock diet only for 8 or 4 weeks. Total cholesterol and free form cholesterol contents in serum, liver and aorta of them were determined, and compared with the each corresponding group which was fed with defatted ginseng control diet for 12 weeks. Total cholesterol and free form cholesterol contents in the serum were increased caused by the alternating diets which was fed on 0.5, 1.0 and 3.0% defatted ginseng diet for 4 and 8 weeks after being fed on stock diet for 8 and 4 weeks, conversely total cholesterol contents in the aorta were decreased by the same alternating diets. Free form cholesterol contents in the serum, liver and aorta of the group which was fed on 1.0% defatted ginseng diet 8 weeks after being fed on stock diet for 4 weeks were increased, but that of the group which was fed alternately on 3.0% defatted ginseng diet were decreased than the corresponding defatted ginseng control diet group.

  • Let X be a smooth, closed, connected spin 4-manifold with $b_1(X)=0$ and signature ${\sigma}-(X)$. In this paper we use Seiberg-Witten theory to prove that if X admits a spin alternating $A_4$ action, then $b^+_2(X)$ ${\geq}$ |${\sigma}{(X)}$|/8+3 under some non-degeneracy conditions.

  • The purpose of the study was to examine alternating motion rate and its variability in children with childhood apraxia of speech (CAS) compared to typically developing children. Six children with CAS aged 9-12 years old and 10 children who were age-matched participated in the study. This study measured tokens per second and variabilities of the rates during the production of /$p^*$ a/, /$t^*$ a/, and /$k^*$ a/. For variability measures of the rates, each participant was asked to repeat speech tasks three times and the average value of the rates and its standard deviation were obtained. The results revealed that the CAS group showed slower rate only at /$k^*$ a/ than the control group. The CAS group exhibited greater variability of AMR at all the tasks than the control group. The results suggested that variability of AMR might be a more distinctive speech feature to children with CAS than the rate of the speech task.

  • In this paper we prove that the alternating groups A_n, for n = p, p+1, p+2 and symmetric groups $S_n$, for n = p, p+1, where p$\ge$3 is a prime number, can be uniquely determined by their order components. As one of the important consequence of this characterization we show that the simple groups An, where n = p, p+1, P+2 and p$\ge$3 is prime, satisfy in Thompson's conjecture and Shi's conjecture.

  • Treatment techniques that affect homeostasis by non-invasive regulation in peripheral organs will advance disease research. Here, we demonstrate a non-invasive method of conditioning within an organ using a low-frequency stimulator superposition of alternating microcurrent wave in stages. It is first applied to the inflammatory response in H3N2-infected sinusitis mice. To check the progress of the treatment, mice were sacrificed every week for 3 weeks, nasal tissue was removed, and the inflammatory response was investigated through H & E staining. The low-frequency stimulation treatment group was found to alleviate the proliferation of epithelial cells and invasion of inflammatory cells compared to the control group as the passage of treatment time. The reduction of inflammatory cytokines in the nasal lavage fluid was observed in H3N2-infected sinusitis mice treated with of low-frequency stimulation using superposition of alternating microcurrent wave compared to H3N2-infected sinusitis mice after 3 weeks. These data demonstrate that low-frequency stimulation device in the form of using alternating current wave superposition on within organs provides a new method to regulate specific physiological functions. Therefore, it is necessary to prove the inhibitory effect of low-frequency stimulation using alternating current wave superposition on inflammatory diseases by various methods through further studies and clinical studies.

  • Let G be a finite non-abelian group. We define the non-commuting graph ${\nabla}(G)$ of G as follows: the vertex set of ${\nabla}(G)$ is G-Z(G) and two vertices x and y are adjacent if and only if $xy{\neq}yx$. In this paper we prove that if G is a finite group with $${\nabla}(G){\simeq_-}{\nabla}(\mathbb{A}_{22})$$, then $$G{\simeq_-}\mathbb{A}_{22}$$where $\mathbb{A}_{22}$ is the alternating group of degree 22.

  • This study was divised to observe the effects of ginseng on the body components of Sprague-Dowley Albino male rats by alternating the diet. Just weaned rats (130 heads, weighing(83 ${\pm}$ 4g) were fed with each stock diets supplemented with 0.5, 1.0 or 3.0% ginseng powder for 4 weeks or 8 weeks, and after that fed with stock diet only for 8 or 4 weeks. Compared with the each corresponding group which was fed with ginseng control diet, the protein, total lipid, total cholesterol and free cholesterol contains in serum, liver and aorta of them were determined. The results obtained was summarized as follows ; Protein and total lipid contents of the rat were decreased, caused by the alternating diets, but total cholesterol and free cholesterol contents were increased in the serum, protein and free cholesterol contents increased, conversely total lipid contents decreased in the liver, and in aorta total lipid and total cholesterol contents decreased, In the view of the above results, it can be seen that the alternating diet (stock diet after feeding with ginseng diet) has an influence on the body components of rat.

  • To study the effect of sequence on DNA structure, the two decamer crystal structures one alternating,d(GTACGCGTAC), and the other non-alternating, d(GGCCGCGGCC), were solved. Crystals of both decamers belong to the hexagonal space group $P6_122$, with one strand in the asymmetric unit. The unit cell constants of the alternating decamer are a = b = 39.26 $\AA$, c = 77.70 $\AA$. The structure was refined with 1,828 reflections from 8.0 to 2.0 Aresolution to an R value of 21.3% with all DNA atoms and 63 water molecules. The isomorphous non-alternating decamer had unit cell dimensions of a = b = 39.05 $\AA$, c = 82.15 $\AA$. The structure was refined with 2,423 reflections from 8.0 to 2.0 $\AA$ resolution to a final R value of 22.2% for all DNA atoms and 65 water molecules. Although the average helical parameters of the decamers are typical of A-DNAs, there are some minor differences between them. The helical twist, rise, x-displacement, inclination and roll alternate in the alternating decamer, but do not in the non-alternating decamer. The backbone conformations in both structures show some differences; the residue G(7) of the alternating decamer is trans for $\alpha$ and $\gamma$ while the trans conformations are observed at the residue G(8) of the non-alternating decamer.

  • A series of fully conjugated polymers containing new arylenevinylene units were synthesized and their light-emitting properties were investigated. A bisphosphonate containing tetraphenyl group was made to react with three different dialdehyde monomers to produce fully conjugated alternating copolymers. The photoluminescence (PL) and the electroluminescence (EL) peak wavelengths of the polymers were varied from 500 nm to 460 nm depending on the polymer structure. Single layer EL devices using the polymers as an emissive layer have been fabricated. The single layer EL devices became visible between 12-22 V and emitted blue light.

  • This paper deals with the magnetic properties under the rotational magnetic field on the electrical steel sheet by using Single Sheet Tester with two excitation coils. Actually, the magnetic flux of stator cores in running motors have the behaviour of rotating and alternating flux. In order to improve motor characteristics, it is require to estimate these magnetic properties. When the magnetic field vectors are rotating around in the plane of the sheet during one period of cycle, the magnetization properties and the core loss are measured and then, the results are compared with the magnetic properties obtained by the alternating magnetic fields.
