This paper pursues a comparative study on the design and function of the ready-made Bo-Son and the Bo-Son Pattern based on teaching and learning materials. It intends to investigate whether the Bo-Son is designed to suit to Kinetics of foot or to give the ease of wearing and taking off. The following results came out through trial wearing. 1) The Bo-Son pattern suggested in teaching materials can not satisfy the wearers with partial modification due to design problem. On the other hand, the ready-made Bo-Son can satisfy them with partial modification. 2) The important factor in designing the pattern of Bo-Son is the posture of foot when putting on it, that is, the height of the heel of the foot from the floor, the length of the heel, the length of toe and the bending angle of toe. 3) As a result of this study, in the design of the improved Bo-Son pattern, it is most suitable when the size of foot is 230mm, the height of the heel of the foot is 12.5cm, and and angle of the front toe of a sock is 35$^{\circ}C$.

In this study, we verified the relationship among the electrical conductivity, chemical durability, and structure of conductive vanadate glass in which $BO_3$ and $BO_4$ and $V^{4+}$ and $V^{5+}$ coexist simultaneously. We prepared samples of vanadium borophosphate glass with various compositions, given by $50V_2O_5-xB_2O_3-(50-x)P_2O_5$(x = 0 ~ 20 mol%) and $70V_2O_5-xB_2O_3-(70-x)P_2O_5$(x = 0 ~ 10 mol%), and analyzed the electrical conductivity, chemical durability, FT-IR spectroscopy, thermal properties, density, and molar volume. Substituting $B_2O_3$ for $P_2O_5$ was found to improve the electrical conductivity, chemical durability, and thermal properties. From these results, we can draw the following conclusions. First, the electrons shift from the electron rich $V^{4+}$ to the electron deficient $BO_3$ as the $B_2O_3$ content increases. Second, the improvement in chemical durability and thermal properties is attributed to an increase in cross-linked structures by changing from a $BO_3$ structure to a $BO_4$ structure.

The structure of the lithium zinc borate LiZnBO3 has been established by single-crystal X-ray diffraction methods. It crystallizes in the triclinic space group P1(Z=2), with unit-cell parameters - $a=5.0915(9)\AA$, $b=5.059(1)\AA$, $c=6.156(1)\AA$, $V=120.6(1)\AA3$ , $\alpha=65.81(1)^{\circ}$, $\beta=65.56(1)^{\circ}$ and $\gamma=59.77(1)^{\circ}$. The structure was determined from 704 unique reflections and refined to the final residuals R=0.039 and wR=0.056. It is characterized by an association of BO3 triangles and LiO4 and ZnO4 tetrahedra. The Li and Zn atoms are disordered around the average positions between Li1 and Li2 atoms or between Zn1 and Zn2 atoms. The disorder can be described by four half-occupied positions about Li1, Li2, Zn1 and Zn2 atoms.

Obturator nerve block has been commonly used for pain management to prevent involuntary reflex of the adductor thigh muscles. One of several options for this block is chemical neurolysis. Neurolysis is done with chemical agents. Chemical agents used in the neurolysis of the obturator nerve have been alcohol, phenol, and botulinum toxin. In the current case, a patient with spasticity of the adductor thigh muscle due to cervical cord injury had obturator nerve neurolysis done with botulinum toxin type B (BoNT-B). Most of the previous studies have used BoNT-A with only a few reports that have used BoNT-B. BoNT-B has several advantages and disadvantages over BoNT-A. Thus, we report herein a patient who successfully received obturator nerve neurolysis using BoNT-B to treat adductor thigh muscle spasm.

This study was carried out to investigate the factors affecting fertilization in vitro of follicular oocytes with frozen-thawed spermatozoa in Korean Native Cattle. The bovine ovaries were obtained at a slaughter house and the follicular oocytes were recovered by aspirating the follicular fluid from the visible follicles of 3~6mm. The bovine oocytes were matured in vitro for 20~24 hours in TCM-199 containing FCS and hormones. The matured oocytes were fertilized in vitro using Percoll-separated frozen-thawed spermatozoa in BO solution. The effects of dilution and fertilization media, capacitating method, concentration of inseminated sperm and time after insemination of fertilization, were observed. The results obtained are summarized as follows : 1. The fertilization rate of frozen-thawed sperm inseminated in BO solution with caffeine and heparin together(56.4%) was higher than that of sperm inseminated in BO solution with either caffeine(10.5%) or heparin(8.9%) and without both caffeine and heparin(0%)(P<0.05). 2. The fertilization rate(56.3%) of frozen-thawed sperm inseminated in BO solution with both caffeine and heparin without preincubation was higher than that of sperm preincubated(2.9%)(P<0.05). 3. The fertilization with high concentration of frozen-thawed sperm(1.4~1.8$\times$107cells/ml) in BO solution containing caffeine and heparin resulted in higher fertilization rate, 76.7%, than the low concentration of sperm(0.8~1.0$\times$107cells/ml), 32.7%(P<0.01). 4. When the oocytes were inseminated with frozen-thawed sperm in BO solution containing caffeine and heparin without preincubation, fertilization rate increased by time and the rates were 5.9, 46.0 and 59.4% at 8, 16 and 24 hours, respectively.

Purpose: Borage oil (BO) and safflower oil (SO) are efficacious in reversing epidermal hyperproliferation, which is caused by the disruption of epidermal barrier. In this study, we compared the antiproliferative effect of dietary BO and SO. Altered metabolism of ceramide (Cer), the major lipid of epidermal barrier, was further determined by measurement of epidermal levels of individual Cer, glucosylceramide (GlcCer), and sphingomyelin (SM) species, and protein expression of Cer metabolizing enzymes. Methods: Epidermal hyperproliferation was induced in guinea pigs by a hydrogenated coconut diet (HCO) for 8 weeks. Subsequently, animals were fed diets of either BO (group HCO + BO) or SO (group HCO + SO) for 2 weeks. As controls, animals were fed BO (group BO) or HCO (group HCO) diets for 10 weeks. Results: Epidermal hyperproliferation was reversed in groups HCO + BO (67.6% of group HCO) and HCO + SO (84.5% of group HCO). Epidermal levels of Cer1/2, GlcCer-A/B, and ${\beta}$-glucocerebrosidase (GCase), an enzyme of GlcCer hydrolysis for Cer generation, were higher in group HCO + BO than in group HCO, and increased to levels similar to those of group BO. In addition, epidermal levels of SM1, serine palmitoyltransferase (SPT), and acidic sphingomyelinase (aSMase), enzymes of de novo Cer synthesis and SM hydrolysis for Cer generation, but not of Cer3-7, were higher in group HCO + BO than in group HCO. Despite an increase of SPT and aSMase in group HCO + SO to levels higher than in group HCO, epidermal levels of Cer1-7, GlcCer-A/B, and GCase were similar in these two groups. Notably, acidic ceramidase, an enzyme of Cer degradation, was highly expressed in group HCO + SO. Epidermal levels of GlcCer-C/D and SM-2/3 did not differ among groups. Conclusion: Dietary BO was more prominent for reversing epidermal hyperproliferation by enhancing Cer metabolism with increased levels of Cer1/2, GlcCer-A/B, and SM1 species, and of GCase proteins.
