With the recent rapid improvement in the standards of life and westernization of dietary lifestyles, the consumption of high-calorie diets such as high-fat and high-protein red meat and instant foods has increased, while less vegetables containing dietary fiber are consumed. In addition to that, stress, erroneous dietary behaviors, and contaminated environments are linked to the risk of developing ulcerative colitis, which is on the rise. Another cause of ulcerative colitis is that involve laxative abuse, including repeated, frequent use of laxatives, and include such conditions as deteriorated bowel function, irritable bowel syndrome, diarrhea, intestinal inflammation, etc. The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of antioxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazine.

Magnetic Resonance Image (MRI) has been used as a safe, conventional and harmless diagnostic tool. However, thermal injuries have frequently been reported during MRI scanning due to the heat generated by the reaction with the magnetic field. It is recommended that metal-containing monitoring devices such as pulse oximetry and ECG monitoring leads should be removed prior to the start of the MRI scan, but these monitoring devices are inevitably placed in children or patients in the intensive care unit who have low compliance with the scan. Since the interaction between the metal probe or wire loop of pulse oximetry and the magnetic field can result in high thermal conduction, full-thickness burn can occur over the entire body surface during the MRI examination. Several cases of thermal burns from pulse oximetry on the fingers have been reported. However, we present a case of a full-thickness burn arising left earlobe in a 2-month-old child caused by the high conduction heat from pulse oximetry metal probe.

In general, the pearlescent pigment is a pigment which was used for optical characteristics like pearl, rainbow and metallic luster. Titanium dioxide coated mica plate developed by DuPont in 1965 is currently being used as a main part of pearlescent pigment for cosmetics. Although the smooth and clear surface substrate laminated with 2 ~ 3 ingredients is thicker than a previous monolayer coated substrate, it has been applied for cosmetics as the optical interference powder to realize stronger shine and brighter interference color than monolayer one. In this study, we developed a new optical interference powder with thinner and higher chroma than a current pearlescent pigment for the strong luster and bright interference color. It was prepared from the manufacturing process, in which the coated titanium dioxide precursor was changed and crystallized by coating and heat treatment process with a half of dividing the coated amount of titanium dioxide. We confirmed the dense coating of titanium dioxide grain with Scanning Electron Microscope and measured superior crystallization degree compared with a monolayer coated pearlescent pigment by X-ray Diffraction. It is concluded that our new pearlescent pigment had higher reflectivity of light and stronger interference color than previous products.

Pulse TIG (Tungsten Inert Gas) welding is often considered the most difficult of all the welding processes commonly used in industry. Because the welder must maintain a short arc length, great care and skill are required to prevent contact between the electrode and the workpiece. Pulse TIG welding is most commonly used to weld thin sections of stainless steel, non-ferrous metals such as aluminum, magnesium and copper alloys. It is significantly slower than most other welding techniques and comparatively more complex and difficult to master as it requires greater welder dexterity than MIG or stick welding. The problems associated with manual TIG welding includes undercutting, tungsten inclusions, porosity, Heat affected zone cracks and also the adverse effect on health of welding gun operator due to amount of tungsten fumes produced during the welding process. This brings the necessity of automation. Hence, In this paper an attempt has been made to build a customerized setup of Pulse TIG welding based on through review of Pulse TIG welding parameters. The cost associated for making automated TIG is found to be low as compared to SPM (Special Purpose machines) available in the market.

1. The furuncle is nail shaped, whitch tip is sharp and root is deep, very dangerous. It's progress is so rapid and it corresponds to the acute suppurative infection of western medicine. 2. The cause and pathology of the furuncle were divided into three parts, inappropriate care (improper diet and excessive sex), surgical trauma (epidernic infection by domestic animal as like cattle, hoarses, pigs, sheep etc), external evil. 3. The early syndrome of the furuncle is swollen pain, various change of color, fidgetiness, restlessness, aversion to cold, headache, nausea and vomitting etc. Though apply acupuncture, there is no pain and bleeding. There may be streak of blood, curdy of muscles and widen swolling. If it is progressed, its sphere becomes diffuse. This is called as the serious case of furuncle(정독주황). 4. The maim treatment of the furuncle is clear away heat and toxic materials. The method was moxibustion, sticking-plaster, purge blood, oral taking the medicine of detoxication and fire extinguishing etc. 5. The main prescriptionst are omisodokyum(五味消毒飮), hwangyeonheadoktang(黃連解毒湯), ohyangyeongyotang(五香連翹湯), hyeongbangpaedoksan(荊防敗毒散) and so on. The main external prescriptionst are okrhosan(玉露散), cheonchugo(千 膏), guildao(九一丹), palyidan(八二丹), taeyulgo(太乙膏), hongyugo(紅油膏) and so on.

The objective of this article is to investigate the medical records written in Seungjeongwon Ilgi ("承政院日記") about Heebin Jang (張禧嬪), who was the mother of King Kyeongjong. She was one of the royal concubines of King Sukjong and later became the queen and then was demoted back to the concubine. The method to do this study was to search the records of Seungjeongwon Ilgi ("承政院日記") from Sukjong 15th year (A.D. 1689) to 20th year (A.D. 1694) on the website databased and serviced by National Institute of Korean History. The results were as follows. According to the website search, Heebin Jang (張禧嬪) suffered from three kinds of diseases. The first was a mastitis right after her delivery. The second was an abscess on the back of her head. The third was a relapse of phlegmturbidity and heat, which was her chronic disease. Also, three features could be found regarding characteristics of Royal medicine. The first was how the queens were taken care of before and after their delivery. The second was who lanced the queen's abscess. The third was how the Royal medicine and people's medicine interchanged.

A conservative pressure-based finite-volume numerical method has been developed for computing flow and heat transfer by using an unstructured grid system. The method admits arbitrary convex polyhedra. Care is taken in the discretization and solution procedures to avoid formulations that are cell-shape-specific. A collocated variable arrangement formulation is developed, i.e. all dependent variables such as pressure and velocity are stored at cell centers. Gradients required for the evaluation of diffusion fluxes and for second-order-accurate convective operators are found by a novel second-order accurate spatial discretization. Momentum interpolation is used to prevent pressure checkerboarding and the SIMPLE algorithm is used for pressure-velocity coupling. The resulting set of coupled nonlinear algebraic equations is solved by employing a segregated approach, leading to a decoupled set of linear algebraic equations fer each dependent variable, with a sparse diagonally dominant coefficient matrix. These equations are solved by an iterative preconditioned conjugate gradient solver which retains the sparsity of the coefficient matrix, thus achieving a very efficient use of computer resources.
