Objectives: The objective of this study was to compare the effects of Sweet Bee Venom(Sweet BV) Therapy between the hand paresthesia patients with Osteoporosis and without Osteoporosis. Methods: This study was carried out to established the clinical criteria of hand parethesia. The patients who had past history of diabeics, neuropathy induced by alcohol or drug and was positive on Myofacial Pain Syndrome Theory were excluded. 32 patients who had hand paresthesia related with unknown-reason was selected by the interview process. And the effects of treatment were analyzed using VAS score before treatment, after treatment, after 1 month and after 3 months. Results and conclusion: After treatment, While Osteoporosis group decrease from $64.81{\pm}7.81$ to $27.21{\pm}7.32$, Non-Osteoporosis group decrease from $58.76{\pm}1.43$ to $24.74{\pm}3.81$ by VAS scores. and After 3 months, While Osteoporosis group increase from $27.21{\pm}7.32$ to $54.96{\pm}9.40$, Non Osteoporosis group increase from $24.74{\pm}3.81$ to $32.43{\pm}5.57$. Non-Osteoporosis group was accordingly more effective than Osteoporosis group after 3 months. So Sweet BV therapy for hand numbness patients without Osteoporosis was e effective than patients with Osteoporosis.

The sodium-cooled fast reactor is among the innovative nuclear technologies selected in the framework of the development of Generation IV concepts, allowing the irradiation of uranium-plutonium mixed oxide fuels (MOX). A fundamental step for the safety assessment of MOX-fuelled pins for fast reactor applications is the evaluation, by means of fuel performance codes, of the integral thermal-mechanical behaviour under irradiation, involving the fission gas behaviour and release in the fuel-cladding gap. This work is dedicated to the performance analysis of an inner-core fuel pin representative of the ASTRID sodium-cooled concept design, selected as case study for the benchmark between the GERMINAL and TRANSURANUS fuel performance codes. The focus is on fission gas-related mechanisms and integral outcomes as predicted by means of the SCIANTIX module (allowing the physics-based treatment of inert gas behaviour and release) coupled to both fuel performance codes. The benchmark activity involves the application of both GERMINAL and TRANSURANUS in their "pre-INSPYRE" versions, i.e., adopting the state-of-the-art recommended correlations available in the codes, compared with the "post-INSPYRE" code results, obtained by implementing novel models for MOX fuel properties and phenomena (SCIANTIX included) developed in the framework of the INSPYRE H2020 Project. The SCIANTIX modelling includes the consideration of burst releases of the fission gas stored at the grain boundaries occurring during power transients of shutdown and start-up, whose effect on a fast reactor fuel concept is analysed. A clear need to further extend and validate the SCIANTIX module for application to fast reactor MOX emerges from this work; nevertheless, the GERMINAL-TRANSURANUS benchmark on the ASTRID case study highlights the achieved code capabilities for fast reactor conditions and paves the way towards the proper application of fuel performance codes to safety evaluations on Generation IV reactor concepts.

Objective : In this study, we have discovered that Korean Bee-Venom therapy is effective in treating various hip joint diseases. For example, A vacular Necrosis, Degenerative Arthritis and Rheumatoid Arthritis. Methods & Results: We have treated three cases of affections of the hip(eg. Degenerative arthritis, Rheumatoid arthritis and Avascular Necrosis of Femoral Head) with Korean Bee-Venom therapy and herbal acupuncture treatments. For acupuncture, Korean Bee-Venom therapy was observed for its pain relieving effects. Korean Bee-Venom therapy was treated on the following acupuncture points: GB29(Koryo), GB30(Hwando:環跳), ST36(Chok-samni:足三理). As the results of these treatments, a little change of inflammation around the hip joint on X-ray scan study was observed. but the degree of pain and range of motion were improved. in addition to general conditions of the patients. Conclusions: Based on the clinical results, Korean Bee-Venom therapy is believed to be effective for treating Avascular Necrosis of Femoral Head, Degenerative arthritis and Rheumatoid arthritis of hip joint. However, it is expected that further studies should be conducted to provide more objective information.

Currently, the pin-by-pin homogenized solvers are a very active research field as they can, unlike the nodal codes, directly predict the local power, while requiring significantly less computational resources than the heterogeneous transport codes. This paper presents a recently developed pin-by-pin diffusion/SP3 solver Tortin, its spatial discretization method and the reflector treatment. Regarding the spatial discretization, it was observed that the finite difference method applied on pin-cell size mesh does not properly capture the big flux change between MOX and uranium fuel, while the nodal expansion method is more accurate but too slow. If the finite difference method is used with a finer mesh in the outer two pin rows of the fuel assembly, it increases the required computation time by only 50%, but decreases the pin power errors below 1% with respect to lattice code reference solutions. The paper further describes the coupling of Tortin with a microscopic depletion solver. Several verification tests show that the SP3 pin-by-pin solver can reproduce the heterogeneous transport solvers results with very good accuracy, even for fuel cycle depletion of very heterogeneous core employing MOX fuel or inserted control rods, while being two orders of magnitude faster.

A simple way to prevent protein hyperglycosylation in Hansenula polymorpha was found. When glucose oxidase from Aspergillus niger and carboxymethyl cellulase from Bacillus subtilis were expressed under the control of an inducible methanol oxidase (MOX) promoter using methanol as a carbon source, hyperglycosylated forms occurred. In contrast, MOX-repressing carbon sources (e.g., glucose, sorbitol, and glycerol) greatly reduced the extent of hyperglycosylation. Carbon source starvation of the cells also reduced the level of glycosylation, which was reversed to hyperglycosylation by the resumption of cell growth. It was concluded that the proteins expressed under actively growing conditions are produced as hyperglycosylated forms, whereas those under slow or nongrowing conditions are as short-glycosylated forms. The prevention of hyperglycosylation in the Hansenula polymorpha expression system constitutes an additional advantage over the traditional Saccharomyces cerevisiae system in recombinant production of glycosylated proteins.

We present the results HELIOS verification against VENUS PWR critical experiments loaded with high plutonium content mixed oxides fuels. The effective multiplication factors are calculated to be slightly supercritical within an acceptable error bound. In the prediction of power shape, HELIOS results are in close agreement with the measured values. The RMS errors of re-normalized calculated fission rate distribution are less than 1.4 % with either explicit or implicit models or micro tubes/rods in each fuel assembly for both ALL-MOX and GD-MOX mock-up cores.

At present, Metal Oxide gas Sensors (MOXs) are widely used in gas detection because of its advantages, including high sensitivity and low cost. However, MOX presents well-known problems, including lack of selectivity and environment effect, which has motivated studies on different measurement strategies and signal-processing algorithms. In this paper, we present an artificial neural network (ANN) that models an MOX sensor (TGS822) used in a dynamic environment. This model takes into account dependence in relative humidity and in gas nature. Using MATLAB interface in the design phase and optimization, the proposed model is implemented as a component in an electronic simulator library and accurately expressed the nonlinear character of the response and that its dependence on temperature and relative humidity were higher than gas nature.
