BACKGROUND/OBJECTIVES: Previous studies have reported that protein supplementation contributes to the attenuation of inflammation. Serious trauma such as burn injury usually results in the excessive release of inflammatory factors and organs dysfunction. However, a few reports continued to focus on the function of protein ingestion in regulating burn-induced inflammation and organ dysfunction. MATERIALS/METHODS: This study established the rat model of 30% total body surface area burn injury, and evaluated the function of blended protein (mixture of whey and soybean proteins). Blood routine examination, inflammatory factors, blood biochemistry, and immunohistochemical assays were employed to analyze the samples from different treatment groups. RESULTS: Our results indicated a decrease in the numbers of white blood cells, monocytes, and neutrophils in the burn injury group administered with the blended protein nutritional support (Burn+BP), as compared to the burn injury group administered normal saline supplementation (Burn+S). Expressions of the pro-inflammatory factors (tumor necrosis factor-α and interleukin-6 [IL-6]) and chemokines (macrophage chemoattractant protein-1, regulated upon activation normal T cell expressed and secreted factor, and C-C motif chemokine 11) were dramatically decreased, whereas anti-inflammatory factors (IL-4, IL-10, and IL-13) were significantly increased in the Burn+BP group. Kidney function related markers blood urea nitrogen and serum creatinine, and the liver function related markers alanine transaminase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase were remarkably reduced, whereas albumin levels were elevated in the Burn+BP group as compared to levels obtained in the Burn+S group. Furthermore, inflammatory cells infiltration of the kidney and liver was also attenuated after burn injury administered with blended protein supplementation. CONCLUSIONS: In summary, nutritional support with blended proteins dramatically attenuates the burn-induced inflammatory reaction and protects organ functions. We believe this is a new insight into a potential therapeutic strategy for nutritional support of burn patients.

Background: After burn patients are discharged from the hospital, they may continue to feel pain and paresthetic sensations at the site of a healed burn and these problems may persist for years. This study was designed to describe the characteristics of these symptoms in terms of intensity, frequency, and influencing factors. Methods: Patients that developed paresthetic sensations at sites of a healed burn were recruited from the pain management center from January 2003 to April 2006. Data was collected using a structured interview protocol. Results: Fifty one adults, with a total body surface area burned (TBSA) of $21.1{\pm}16.3%$ aged $42.0{\pm}12.9$ years were studied. A paresthetic sensation was reported to be present every day in 52.9% (27/51) of the subjects. A variation in the intensity was most commonly related to changes in the weather. A tight sensation and itching types of sensations were significantly more frequent in patients with more extensive injuries. Conclusions: Recognition and understanding of the chronic paresthetic sensation that many burn patients continue to experience at sites of a healed burn deserve further attention. Not only do clinicians need to be aware of these problems but also strategies for prevention and alleviation shou\d be explored.

Purpose: Post-burn pruritus is one of the most prevalent complications experienced by burn patients. Though medications are prescribed for pruritus, managing this condition can prove challenging. The aim of this research was to develop and disseminate non-pharmacological self-management educational resources, and subsequently evaluate the effectiveness of implementing a percussion therapy approach. Methods: A one-group pretest-posttest design was employed to evaluate the effect of percussion therapy on one hundred patients, all of whom had suffered deep second-degree burns and undergone skin graft surgery. Variables such as the severity of pruritus, distress caused by pruritus, and satisfaction with pruritus treatment were scrutinized. A paired t-test was conducted to compare these variables before and after the intervention. Results: The majority of participants were diagnosed with third-degree burns, and the average Total Body Surface Area (TBSA) affected was 25.2%. Post-test results revealed a marked reduction in both severity and distress caused by pruritus. The intervention led to significant decreases in average severity and pain due to itchiness, and an increase in the satisfaction level following the application of percussion therapy. Conclusions: The implementation of the percussion was identified as effective in diminishing post-burn pruritus, alleviating pruritus-associated pain, and enhancing satisfaction with pruritus treatment. The percussion approach presents itself as a non-invasive, non-pharmacological strategy for managing pruritus in burn patients.

This paper presents the capability to use QuickBird imagery for effects of forest disturbance in Okgye burned area. Particular attention of this paper deals with the NBR-derived mapping burn severity on QuickBird imagery to locate reliable rehabilitation(namely, secondary succession) over postfire surface. Comparisons of the mapping forest disturbance derived from QuickBird NBR data and the mapping burn severity derived from Landsat ${\Delta}NBR$ data show substantial agreement (KHAT value =0.7886). The method calculated from the correlation between QuickBird wetness and Landsat ETM+ band7 may have application to forest harvest disturbance.

Experimental studies have been performed to observe the basic phenomena of waste bed combustion in MSW incinerator. A reduced scale apparatus was utilized to simulate the combustion behavior in real plant with 1-dimensional transient behavior at the experimental setup, which uses wet cubic wood with ash content as simulated waste. LHV (lower heating value) of solid fuel, fuel particle size and flow rate of combustion air were taken as important parameters of the bed combustion. For the quantitative analysis, FPR (flame propagation rate), TBT (total burn-out time) and PBT (particle burn-out time) was defined. LHV represent the capability of heat release of the fuel, so that a higher LHV results in faster reaction rate of the fuel bed, which is shown by higher FPR. Fuel particle size is related with surface area per unit mass as well as heat and mass transfer coefficient. As the particle size increases the FPR decreases owing to decreasing specific surface area. Air injection supplies oxygen to the reaction zone. However oversupply of combustion air increases convection cooling of the bed and possibly extinguishes the flame.

Three grades of activated carbon fibers (ACFs) were prepared from various precursors of plantic, synthetic, and mixed fabrics of viscose rayon and cotton. The ACFs an exhibited type I isotherms on the adsorption of nitrogen or argon. Micropore analysis revealed that the ACFs have uniform micropore size distribution in which their peak diameters were in the range of $5.6{\pm}0.3{\AA}$. The BET surface area of ACFs up to $1600m^2g^{-1}$ was proportional to the adsorption capacity of iodine. The BET values of the ACFs prepared were proportional to the burn-off degree of the products.

Analysis on forest through satellite image data can be obtained from normalized burn ration (NBR) and normalized difference vegetation index (NDVI) from descriptive information of reflection on the earth's surface recorded each waveband. This study focuses on the efficiency of NBR through comparative analysis after obtaining NBR and NDVI of images form 1 you, 2 years and just after the forest fire and the time of forest-preserved of the area before the forest fire in Sacheon myeon, Cangneung City where the forest fro broke out. As a result, it shows dynamic changes with greater range that differences between NBR images rather than differences between NDVI images, which means it would be better to use NBR image for the analysis of the degrees of damages from forest fire or the status of vegetation restoration and also NBR image more distinctly shows both than NDVI image in forest fro damage area.
