The aim of this study was to establish the superiority of ohmic heating over conventional heating for the sterilization of mulberry juice. Heat treatment of fresh juice significantly reduced the concentration of soluble solids, lowered the pH, and lowered the reducing sugar content (p<0.01). Color measurements showed decreases in the L and a values and increases in the b, H and C values after heat treatment, although the total color differences were smaller after ohmic heating than after conventional heating of fresh juice. The antioxidant capacities, such as reducing power, FRAP, and DPPH, decreased in the order of fresh juice, ohmically heated juice and conventionally heated juice. Furthermore, the anthocyanin, flovonoid, and total antioxidant capacities of the juices significantly decreased in the same order. Sensory evaluations showed no difference between fresh and ohmically heated mulberry fruit juice excluding off-flavor, whereas conventionally heated juice received significantly lower evaluations. The microbial counts were zero in the juice after either heat treatment. Thus, ohmic heat treatment can be effectively used to sterilize fresh mulberry juice to obtain good shelf life with minimal physicochemical, color, antioxidant and sensory deterioration.

The contents of sucrose and reducing sugars of cotyledons and hypocotyls of Ricinus communis L were increased slightly during cold treatment at $4^{\circ}C$. The concentration of total amino acids was increased continuosly during cold treatment. But the contents of hydrophilic amino acids, Asp/Asn, Glu/Gln, Thr, Ser, Ala and cationic amino acids, Arg and Lys were varied dramatically with the cold treated time. The cold treatment induced 24, 52, 54, 55, 56 and 73.5kD of proteins in cotyledons and 55, 56 and 73.5kD of proteins in hypocotyls. 24, 42, 49 and 52kD of proteins in cotyledons and hypocotyls were boiling stable. They were not denatrated by boiling at $100^{\circ}C$.

Objectives : Schizophreniform Disorder can be put as pre-stage of Schizophrenia, which is known as one of the most common mental disorder. Many studies have shown that Antipsychotic Treatment for Schizophrenia has many side effects such as EPS(Extrapyramidal Symptoms), and recently it has been found that even Non-Antipsychotic Treatment has side effects such as weight gain. This clinical study was aimed to search the therapeutic effects of Oriental medicine in Schizophreniform Disorder, and in reducing the side effects of Western medicine. Methods : We treated the patient diagnosed as Schizophreniform Disorder, whose chief complaint was auditory hallucination, with herbal medicine and acupuncture. Improvement in her clinical symptoms were recorded daily. We also used Emotional Freedom Techniques to control her anxiety effectively. Results : Auditory hallucination and extrapyramidal symptoms such as tremor disappeared. The patient's anxiety was controlled by Emotional Freedom Techniques effectively. Conclusions : From the above results, we conclude that Oriental medical treatment is effective in treating clinical symptoms of Schizophreniform Disorder, as well as in reducing the side effects of Western medicine.

The purpose of this study is to evaluate the adhesive properties of polyurethane mixed aqueous dispersions by omitting the primer, dealing with the preparation of skins for synthetic leather with excellent adhesion by omitting the pre-treatment process. The two-component mixed polyurethane water dispersion was prepared by synthesizing an ester-based polyurethane resin (PU-T) and a carbonate-based polyurethane resin (PU-C) to obtain the final resin. As a result of measuring the peel strength of the adhesive specimens omitting the pre-treatment agent, it was confirmed that the state adhesive strength (ethylene vinyl acetate (middle): $4.2kg_f/cm$ and rubber (outsole): $4.4kg_f/cm$) there was. This makes it possible to omit the pre-treatment process which has been indispensably used in the shoe manufacturing process, thereby reducing the process time and reducing the amount of volatile organic compounds (VOCs) generated in the pre-treatment product, resulting in environmentally advantageous.

Background : Patients with frozen shoulder have pain and limited range of motion (ROM) at the affected shoulder. Shoulder pain of these patients usually decreases with recovery of range of motion. The aim of this study is to identify effects of static stretching and hold-relax on recovering ROM and reducing pain of patients with frozen shoulder. Methods : In this study, 15 patients with frozen shoulder who were only treated with physical therapy were recruited. Patients who received any surgical procedure or hydrotherapy were excluded. The subjects were divided randomly into 3 groups; control(n=5), static stretching(n=5) and hold-relax(n=5) groups. Patients were treated with stretching and the total number of treatments was 12 times. The ROM was measured at baseline, after fourth, eighth and final treatments. Shoulder pain and disability index(SPADI) scores were assessed before and after doing all treatments. Repeated measures ANOVA was used to analyze ROM change within each group. Changes of ROM between groups was analyzed by one way ANOVA followed by post hot analysis(Tukey's HSD). SPADI score within each group analyzed using Wilcoxon signed ranks test. A p-value<0.05 was considered statistically significant. Study Design : Repeated measures design. Result : There were significant differences of ROM in both treatment groups except internal rotation of static stretching group. ROM was significantly increased in treatment groups compared with control group, but the difference of ROM change between two treatment groups did not differ significantly. SPADI scores for treatment groups significantly decreased compared with pre-SPADI score. Conclusion : The result suggests that hold-relax can be more effective than static stretching to recover range of motion and alleviate shoulder pain on patients with frozen shoulder.

Background and Objectives Breast reconstruction has the advantage of reducing the loss of the body image of patients after mastectomy surgery, and also improving the quality of the social and sexual life of breast cancer patients. However, in surprising and unfortunate number of patients, acute postoperative pain persists beyond the normal course of postsurgical recovery. We set out to investigate the effect of local dynamical micro-massage (LDM) treatment for achieving pain relief and reducing other postoperative complications. Materials and Methods We performed a retrospective analysis on 58 patients who underwent LDM treatment for postoperative pain management at Soonchunhyang University Bucheon Hospital between February 2017 and June 2019. Those patients who complained of persistent postoperative pain, which was uncontrollable with medication, were treated with LDM. The degree of pain and discomfort with contracture were recorded using numerical rating scale (NRS) scoring system with numbers from 0 to 10 ('none' to 'worst'). Results The median NRS score of pain was reduced by 62.3% from the start to the end of LDM treatment (p<0.001). Further, the NRS score of discomfort with contracture was reduced 66.0% (p<0.001). There was no complication related to the LDM treatment. Conclusion Dual-frequency ultrasound LDM can be an effective therapeutic option for persisting pain after breast reconstruction surgery. It was also effective in improvement of discomfort with contracture and erythema of the surgical wound.

This study investigated the effects of the prescribed instructional strategy for reducing students' connecting errors in learning chemistry concepts with multiple external representations by students' field independence-dependence. Seventh graders (N=126) at a coed middle school were assigned to control and treatment groups. The students learned "Boyle's Law" and "Charles's Law" for two class periods. Results revealed that the students in the treatment group scored significantly higher than those in the control group in a conception test. The scores of the treatment group were significantly higher than those of the control group in a motivational learning test, especially in 'attention' of the test. However, there was no significant interaction between the instruction and students' field independence-dependence in the two tests. Most students in the treatment group perceived the instruction positively in cognitive and motivational aspects.

Background: In pediatric dentistry, fear and anxiety are common among children. Local anesthetics (LA) are widely used to control pain and reduce discomfort in children during dental treatment. Topical anesthetics play a vital role in reducing pain and the unpleasant sensation of a needle puncture in children. Peppermint oil has been extensively used for various diseases. However, its anesthetic properties remain unknown. Peppermint oil, used in mouthwashes, toothpastes, and other topical preparations has analgesic, anesthetic, and antiseptic properties. This study aimed to compare and evaluate pain perception following the topical application of peppermint oil versus lignocaine spray before an intraoral injection in children, aged 8-13 years. Method: Fifty-two children, aged between 8-13 years, who required local anesthesia for dental treatment were divided into two groups of 26 each by simple random sampling (Group 1: 0.2% peppermint oil and Group 2: lignocaine spray). In both groups, physiological measurements (e.g., heart rate) were recorded using pulse oximetry before, during, and after the procedure. Objective pain measurement (Sound Eye Motor (SEM) scale) during administration and subjective measuremeant (Wong-Baker Faces Pain Rating Scale (WBFPRS)) after LA administration were recorded. This was followed by the required treatment of the child. Physiological parameters were compared between the two groups using an independent t-test for intergroup assessment and a paired t-test and repeated-measures ANOVA for intragroup comparisons. The Mann-Whitney U test was used to analyze the pain scores. Results: Intragroup mean heart rates, before, during, and after treatment were statistically significantly different (P < 0.05). However, the intergroup mean pulse rates did not differ significantly between the two groups. The mean WBFPS score in the lignocaine spray group was 4.133 ± 2.06 was statistically different from that of the peppermint oil group (0.933 ± 1.03; P < 0.001^*). The mean SEM score was significantly lower in the peppermint oil group than that in the lignocaine spray group (P = 0.006). No negative effects were observed in this study. Conclusion: 0.2% peppermint oil was effective in reducing pain perception.

PURPOSE: This study aimed to determine the changes in the lumbar herniation index, Oswestry disability index (ODI), visual analog scale (VAS), and lumbar flexion range of motion (ROM) following the application of high velocity- low amplitude (HVLA) technique and depression therapy in patients with lumbar herniation discs, and thus to provide a clinical basis for the treatment of lumbar herniation discs. METHODS: We included 45 patients with lumbar herniation discs who were assigned equally to three groups: HVLA technique, depression therapy, and control group. Three times a week for 4 weeks, conservative therapy plus Maitland's lumbar spine rotation technique was applied to the HVLA technique group for 30 min and conservative therapy plus decompression therapy for 30 min to the decompression therapy group, while only conservative therapy was applied to the control group. The lumbar herniation index and Korean version ODI were measured twice before starting and after completing the treatment. The VAS and lumbar flexion ROM were measured before and after each treatment session for twelve. The collected data were analyzed using SPSS software version 21.0. RESULTS: The lumbar herniation index was significantly lower in both the HVLA technique and decompression therapy groups compared to the control group, with decompression therapy being the most effective in reducing the lumbar herniation index. Significant improvements were observed in the ODI, VAS score, and lumbar flexion ROM across all three groups, with HVLA technique being the most effective. CONCLUSION: HVLA Techniqueand decompression therapy were more effective than conservative therapy in reducing the lumbar herniation index, ODI, and VAS scores, and in increasing lumbar flexion ROM. This suggests the importance of combining HVLA technique or decompression therapy along with conservative physical therapy for the effective treatment of lumbar herniation discs.

An experiment was conducted to determine how broiler performance, feces and litter concentration of N can be maintained and whether NH3 gas concentration can be reduced with reducing dietary CP, adding ALUM(AL2(SO4)3.14H20) in litter and supplementing with amino acid and vitamin D in feed. The experiment was divided into a starter period(1 to 21d) and grower period(22 to 42d), each having three different CP with 90 birds per treatment of 3 replications. The CP treatments consisted of a mean CP of 23.0(control 71), 20.4 (72) and 18.0 (73) % for starter and 21.0(control 71),19.3 (72) and 17.0 (73) % for grower, respectively, but with similar amino acid levels as the control. Alum was mixed in each treatment except control treatment with 200g in kilogram litter(rice bran) weight. Results suggested that reducing CP below control in the diets fed during 3wks and 6wks slightly increased feed gain and slightly decreased feed intake and weight gain. However, there were no significant difference among treatments. Reducing CP caused NH3 gas concentration to decline by 74.8 - 80.9% when Alum was mixed in litter(P < 0.05). Litter N concentration did not show any difference(P > 0.05) among treatments. These results suggest that dietary manipulation with adding Alum in litter show for significant reducing NH3 gas concentration while maintaining acceptable Production performance from broiler.
