  • In this study, the fatty acid content and quality characteristics of the massless enegy treated commercial milk products stored at $30^{\circ}C$ were investigated. The pH of pasteurized milk decreased significantly. UHT milk showed also significant decrease in pH to 4.70~5.72 on the 8th day of storage which was higher than control even there was no significant differences. The acidity of pasteurized milk decreased significantly from the 2nd day of storage to 0.13~0.65% in treatments and control and control was 0.94% at the 8th day of storage and 0.35% in the treatment of ultra high temperature milk. The solid content of pasteurized milk was $7.5^{\circ}Bx$ at 1 day after storage, which showed significant differences from the $11.2^{\circ}Bx$ in the treatment. Pasteurized milk showed more bacterial growth in the treatment than in the control. After 4 days of storage, there was no bacterial count in pasteurized milk but it increased significantly $1.9{\times}10^8$ and $4.5{\times}10^6$ each in UHT milk. Lactic acid bacteria were detected in the curd $2.0{\times}10^6$ in the control and $2.0{\times}10^8$ in the treatment at the 4th day. Palmitic acid content in the saturated fatty acid was the highest at 35.4~41.4% in both pasteurized and ultra high temperature milk. In the UHT milk, linolenic acid was significantly increased to 3.8% in the treatment compared with 2.9% in the control at the 4th day of storage. Therefore, commercial ultra high temperature milk with physical treatment to increase beneficial bacteria showed significant difference compared to the control after 5 days of storage in this experiment.

  • This study addressed soil disturbances following harvesting as well as soil physical and hydrological properties within three first-order headwater catchments characterized by ephemeral-intermittent streams. Four treatments representing a range of potential Best Management Practices(BMPs) for ephemeral-intermittent streams were used; BMP1, BMP2, clearcut and reference. This study includes 1 year of pre- and post-harvest observations. Results showed that post-harvest disturbances were closely related with harvesting intensity and generally tended to reflect changes in soil physical and hydrological properties following harvest with the except of bulk density and porosity. Forest clearcutting decreased macroporosity and saturated hydraulic conductivity, and increased soil resistence as a result of severe soil disturbances thereby increasing soil erosion. These impacts were reduced by implementing two BMP treatments during harvesting activities. The finding support the use of either BMP treatments for ephemeral-intermittent streams, however, the additional measure of leaving logging debris in BMP2 did not cover enough soil surface to reduce erosion.

  • Freshly harvested seed of Chinese milk vetch (Astragalus sinicus L.; CMV) was strongly dormant because of hardseedness. Seeds of freshly harvested germinated only 8% while clipping the seed coat completely overcome the innate dormancy, which indicates inhibition of germination of the seed is mainly due to seed coat (87%). The dormant (intact) hard seeds did not imbibe water whereas the non-dormant (clipped) seeds took up rapidly. In natural environment condition, the hard seed coat dormancy was broken only after 5 months after seed harvest. To break such a strong seed coat dormancy, the chemical and heat treatments were effective. Concentrated sulfuric acid was more effective than dry heat and hot water treatments. Hot water treatment improved germination but the germination percentage was less than 41%. Treatments increased germination due to its effect on the seed coat integrity. A scanning electron microscope reveled that disruption of seed coat layers and subsequent development of numerous crack in the hilum region of the seed and on the seed coat surface of concentrated sulfuric acid treatment and formation of cracks in the dry heat treatments, respectively, were observed in the seed coat surface, which served as water entry points.

  • Background: Transcutaneous electrical nerve stimulation (TENS), manual acupuncture (MA), and spinal cord stimulation (SCS) are used to treat a variety of pain conditions. These non-pharmacological treatments are often thought to work through similar mechanisms, and thus should have similar effects for different types of pain. However, it is unclear if each of these treatments work equally well on each type of pain condition. The purpose of this study was to compared the effects of TENS, MA, and SCS on neuropathic, inflammatory, and non-inflammatory pain models. Methods: TENS 60 Hz, 200 ㎲, 90% motor threshold (MT), SCS was applied at 60 Hz, an intensity of 90% MT, and a 0.25 ms pulse width. MA was performed by inserting a stainless-steel needle to a depth of about 4-5 mm at the Sanyinjiao (SP6) and Zusanli (ST36) acupoints on a spared nerve injury (SNI), knee joint inflammation (3% carrageenan), and non-inflammatory muscle pain (intramuscular pH 4.0 injections) in rats. Mechanical withdrawal thresholds of the paw, muscle, and/or joint were assessed before and after induction of the pain model, and daily before and after treatment. Results: The reduced withdrawal thresholds were significantly reversed by application of either TENS or SCS (P < 0.05). MA, on the other hand, increased the withdrawal threshold in animals with SNI and joint inflammation, but not chronic muscle pain. Conclusions: TENS and SCS produce similar effects in neuropathic, inflammatory and non-inflammatory muscle pain models while MA is only effective in inflammatory and neuropathic pain models.

  • Purpose: To provide the basic method for physical therapy to contribute to early stage treatment of a burned patients. We investigated whether or not carbon arc lamp treatment and low level laser one among various laser treatments have the effect of reducing Cytokine, and to elucidate the effect of carbon arc lamp treatment and laser one. Methods: The 6-week old BALB/c types of 92 mice were used for the experimental test, and they were burned with $100^{\circ}C$ water, they were divided into 4 groups in accordance with the method of treatment respectively. And the blood and the tissue from the subject of each group were extracted and analyzed each time after they were cured for 3, 6, 9 days. For the analysis of the results, SPSS statistical program was used in this study. Results: The quantity of $TNF-{\alpha}$ and $IL-1{\beta}$ within the blood of a burned mouse increased more than that of a normal mouse(p<0.01). In only a burned mouse, carbon arc lamp treatment gave the effect on the decrease of $TNF-{\alpha}$ thickness the 6th day to the 9th day(p<0.01). $IL-1{\beta}$ quantity was more decreased than that of control group around the 6th day. In comparison with only a control group, low level laser treatment has more significant effect in decreasing the quantity of $TNF-{\alpha}$ a and $IL-1{\beta}$ than the two different methods(p<0.01). In case that the two treatment methods, carbon arc lamp treatment and low level laser, were executed together, there was the effect of decreasing $TNF-{\alpha}$ until the 6th day(p<0.01). Conclusion: Both low level laser treatment and carbon arc lamp one would be able to have an effect on the inflammation inhibition of burned patients and tissues reproduction. However, it must be also considered for the two treatments to be done at the same time.

  • The purposes of this study was to evaluate the effect of low power GaAsAl laser on tissue contraction in a linear incision wound on rat skin. The linear incision wound was made on the midline of the backside in the experimental animals. Low power laser applications with different intensities such as 3, 6, or 10 mW were applied to the experimental animals twice a day for 10 days. On either the seventh or tenth postoperative day, the quantitative analysis of the inflammatory reaction surrounding the linear incision wounds on the rats were performed using enzymatical analysis of myeloperoxidase (MPO) activity. The number of neutrophil was $.07-1.0{\times}106/m{\ell}$ from a normal blood sample that was obtained from the normal experimental animals. Each concentration of neutrophil showed .04-.62 unit activity of MPO. Therefore, the 6 unit activity of MPO per neutrophil was $.57{\pm}.014{\times}10^{-6}$ unit. On the 7th and 10th post operative day, non treated tissues demonstrated increased MPO activity as compared to that of normal tissue. These data indicated that the inflammatory reaction of tissue was induced after wound induction and the MPO activity were increased in the inflammed tissues. While both 3 mW or 6 mW intensity of laser treatments did not affect the tissue MPO activity, 10 mW intensity of laser treatment significantly decreased the tissue MPO activity on the 7th and 10th post operative day. These data demonstrated that only 10 mW intensity of laser treatment successfully suppressed tissue inflammatory reaction after wound induction. In conclusion, these findings suggested that 10 mW of GaAIAs laser treatments effectively suppressed the inflammatory reaction of tissue that was induced during the wound healing process.

  • The purpose of this study was to identify the differences in pulmonary functioning after respiratory exercise with IPPB (Intermittent Positive Pressure Breather) in patients with progressive muscular dystrophy (PMD). The subjects were 46 patients with PMD who were admitted to the Rehabilitation Medicine Department of Youngdong Severance Hospital. The subjects were assigned into one of 2 groups. The control group received comprehensive treatments such as ROM exercise, deep breathing exercise, moist hot packs, and ultrasound twice a day while admitted at the Rehabilitation Medicine Department. Unlike the control group, the subjects at the experimental group received respiratory exercise treatment with IPPB. The subjects were admitted for 10~19 days, and the average length of hospital stay was 12.2 days. Pulmonary functioning was evaluated at admission and discharge by SENSOR MEDICS. The data were analyzed by a paired t-test and a independent t-test. The results were as follows: 1) The change of each parameter of pulmonary function tests were significantly improved in all groups after respiratory exercise treatment during admission (p<0.05). 2) By comparing the change of each parameter of pulmonary function tests between the experimental group and control group, the parameters of vital capacity (VC), forced vital capacity, forced vital capacity predicted (FVCP) and forced expiratory volume in 1 second (FEV1) were significantly improved in the experimental group which had received the pulmonary exercise treatment with IPPB (p<0.05). In conclusion, this study suggests that the pulmonary exercise treatments with IPPB facilitated improvement in the pulmonary functioning for the PMD patients during their hospital stay.

  • Objective: This study was conducted to investigate the effect of high-intensity laser therapy(HILT), transcutaneous electrical nerve stimulation(TENS), and ultrasound(US) treatment on pain, grip strength, and hand function in patients who had undergone carpal tunnel syndrome surgery. Design: A randomized controlled trial. Methods: Thirty patients who had undergone carpal tunnel syndrome surgery were randomly assigned to receive either TENS combined with HILT, US combined with HILT, or only HILT as the control group. Treatments were applied around the surgical site, and pre- and post-treatment changes were evaluated. Pain was assessed using NPRS, hand symptoms using CTS-6 and BCTQ-SSS, grip strength with an electronic dynamometer, and hand function using BCTQ-FSS. Treatments were administered seven times over two weeks. Results: The pain and symptoms were significantly reduced(p<0.05) and grip strength and hand function were significantly increased(p<0.05) after treatment compared to before treatment for all subjects. Pain was significantly reduced(p<0.05) and grip strength was significantly increased(p<0.05) in the TESN+HILT group and US+HILT group compared to the Control group. Hand symptoms were significantly reduced(p<0.05) and hand function significantly increased(p<0.05) in the TENS+HILT group compared to the Control group. Conclusions: TENS combined with HILT was found to be more effective than US combined with HILT in reducing pain and symptoms and improving grip strength and hand function in patients following carpal tunnel syndrome surgery. These findings suggest that these treatment modalities can be beneficially applied in clinical practice.

  • In order to investigate the effect of physical forms of starter diets on performance, weaning age, nutrient digestibility and rumen biochemical factors, 24 female of neonatal Brown Swiss calves (average body weight of $39.5{\pm}1.2kg$) were randomly assigned to three treatments. Dietary treatments were mashed (MS), pelleted (PS), and texturized (TS) starter using 8 calves from birth till 90 days of age in each treatment. Diets were formulated to be iso-nitrogenous with 21% crude protein. Based on the experimental results, calves that received PS and TS diets, had significant higher average daily gain (ADG) than those receiving MS (p<0.01). Dry matter intake in calves fed PS and TS was greater than calves fed MS (p<0.05), but there was no significant difference in feed efficiency. Treatments had no effect on initiation of rumination. Weaning age of calves in MS was longer than the other two treatments (p<0.05). Crude protein and organic matter digestibility in MS treated calves were lower than other treatments (p<0.05). No differences were observed in neutral detergent fiber (NDF) and ash digestibility among treatments (p>0.05). Ruminal pH was higher (p<0.01) in MS than the other groups, but ruminal ammonia (g/dl) concentration was not different among the treatments. Body measurements such as body length, pin width, hip width, pin to hip length, size of metacarpus and metatarsus bones, hip height, wither height, stomach size and heart girth were not significantly different among the treatments. Overall, it is concluded that starter diets in the form of pellet and texture can improve performance in neonatal Brown Swiss calves compared to the mashed form.

  • Purpose: This research was conducted to compare the effects of drug therapy, physical therapy, and exercise on pain, disability, and depression in patients with chronic low back pain. Methods: The research design of this study was a nonequivalent control group pretest-posttest design. The subjects of this study were 28 patients for the drug therapy & physical therapy, 24 patients for the drug therapy & exercise, and 22 patients for the physical therapy & exercise. Data was collected by MVAS, Oswestry disability questionnaires, and questionnaires of depression. It was analyzed by paired t-test for effectiveness, ANOVA, and Scheffe for comparison of the effects of the 3 experimental treatments, using SPSS/WIN 12.0. Results: There were no effects of drug therapy & physical therapy on pain, disability, and depression. However, there were effects of drug therapy & exercise and the physical therapy & exercise on pain, disability, and depression. The effects of physical therapy & exercise on pain, disability, and depression were the greatest, but there was no statistically significant differences between the drug therapy & exercise and the physical therapy & exercise. Conclusions: Exercise is regarded as a more effective and easily accessible nursing intervention to apply alone than drug therapy or physical therapy simultaneously in reducing pain, disability and depression.
