Background and Objectives : The purpose of this study was to classify patients with unilateral vocal fold paralysis according to their fixed location and to analysis the effects of two treatment methods by early voice therapy and injection laryngoplasty. Materials and Methods : Twenty patients who were classified as full abduction and slight abduction according to the position of paralysis were treated injection laryngoplasy, and 23 patients were treated by voice therapy. Twenty patients were treated injection laryngoplasy and 23 patients were treated voice therapy. Results were evaluated by acoustic analysis, electroglottography, cepstrum analysis before and after therapy. The voice therapy was conducted by improving the larynx movement and glottal contact, whilst removing hypertension of the supraglottic and use the breathing. Results : Significant improvement was found in the acoustic parameter, cepstrum parameter, and EGG before and after treatment in both groups. There was no significant difference between the two groups when compared before and after treatment to compare the effects of injection laryngoplasty and voice therapy. Conclusion : The initial treatments for unilateral vocal cord paralysis are injection laryngoplasty and voice therapy. however, there is no precise standard about which method should be applied first. Therefore, in this study, we tried to classify patients according to their paralysis position and then apply two methods. The results of this study suggest that voice therapy and Injection laryngoplasty at the initial stage is a very useful method to improve voice quality of vocal fold paralysis and improve laryngeal function.

Optimum design of a viscoelastic damping layer which is unconstrainedly cohered on a steel plate is discussed from the viewpoint of the modal loss factor. Themodal loss factor is analyzed by using the energy method to the base steel plate and cohered damping layer. Optimum distributions of the viscoelastic damping layer for modes are obtained by sequentially changing the position of a piece of damping layer to another position which contributes to maximizing the modal loss factors. Analytical procedure performed by using this method simulated for 3 fundamental modes of an edge-fixed plate. Simulated results indicate that the modal loss factor ratios can be increase by as much as 210%, or more, by optimizing the thickness distribution of the damping layer to two times of the initial condition which is entirely covered. Optimum configurations for the modes are revealed by positions where added damping treatments become most effective. The calculated results by this method are validated by comparison with the experimental results and the calculated results obtained by the Ross-Ungar-Kerwin's model in the case of the layer is uniformly treated over the steel plate.

With the aim of investigating the differences in the quality traits between Korean native chicken (Hanhyup, KNC) and broilers commonly used in two different traditional Korean cuisines, the chemical composition and sensory properties of breast and thigh meat from the two chicken strains were assessed. KNC for baeksuk (chicken meat braised in soup with various Oriental medicinal plants; KNL), KNC for samgyetang (similar to baeksuk but young chickens and ginseng are used; KNS), broiler for baeksuk (BL), and broiler for samgyetang (BS) were used as treatments in this study. KNL and KNS contained higher protein but lower fat content than BL and BS. The $L^*$ values of breast and thigh meat, but not the $a^*$ values, were significantly different between KNS and BS, whereas significant differences in both values were observed between KNL and BL. Compared to the other three types of chickens, KNS contained the highest total and insoluble collagen content, and KNL and BL showed higher inosine-5'-monophosphate content in their meat. Overall, KNL and KNS contributed darker, less tender meat with higher protein and less fat content together with more n-3 fatty acids, as opposed to their counterparts used for the same cuisines. Based on the results of the sensory analysis, even though there are some differences in physiochemical traits, different chicken sources do not differ in overall sensory quality. This information can help consumers to understand better the meat available for their preferred traditional cuisines.

Objectives The purpose of this study was to investigate Korean medicine treatment on hemifacial spasm and to suggest future research direction. Methods We used seven electronic databases to find articles on Korean medicine treatment of hemifacial spasm and by analyzing the title, abstract, and main text, articles elucidating on Korean medicine treatment on hemifacial spasms were included. Results A total of 68 articles were searched from seven electronic databases. Excluding duplicate articles and articles that satisfied the exclusion criteria, nine articles were included in this study. Acupuncture was used in nine cases, herbal medicine in five cases, physical therapy in three cases, and cupping therapy in one case. In acupuncture, general acupuncture was used in five cases, pharmacopuncture in three cases, and Meridian tendino-musculature acupuncture and thread-embedding therapy in two cases each. Gamigwibi-tang used in two cases was the most frequently used herbal medicine. In physical therapy, carbone, hot pack, interferential current therapy, and silver spike point were used in two cases each. Conclusions It was confirmed that Korean medicine treatment for hemifacial spasm was attempted in varying methods and nearly all cases included in this study showed improvement. However, because of the low level of evidence due to the nature of these case reports, further studies should be conducted for an objective comparison and analysis on the effect of Korean medicine treatment compared to existing treatments.

Objective : The purpose of the study is to compare the effects and efficacy of both treatments. Methods : 2 groups were divided among 6 patients who admitted to Jeonju Wonkwang hospital attached to Wonkwang University from 2009. jan. 1 to 2009. feb. 28 were diagnosed as herniated lumbar disc by lumbar CT or MRI. Each groups were treated by decompression therapy and chuna traetment daily and were measured under visual analogue scale and ODI score starting from the day of admission, after 1week, and second week to compare the results. Results and Conclusions : Decompression therapy and chuna treatment both showed effects on treating the patients though chuna traetment apparently revealed to be slightly more efficient. Due to the lack of abundant clinical data it was not objective in a strict sense but it was clinically meaningful enough.

In the first of two experiments, chemical composition (Ash, CP and CF contents), nutritive value (in vitro organic matter disappearance "lVOMD" and energy content "ME") and nitrogen retention of chopped date fronds (CDF) as affected by chemical treatment (CT) and storage duration (SD) were investigated. The experimental design was a completely randomized block, arranged in a $3{\times}4$ factorial, with 3 (CT) and 4 (SD) as the main factors using 2 replications / treatment. Three chemical treatments, were used : Control (With zero or no chemical treatment); treatment with 4% urea solution (w /w) and treatment with 4% urea + Date syrup extract (DS). The 4 (SD) were: Control (immediately after opening - without any storage or zero time storage); one month storage period; two months storage period and three months storage period. Both (CT) and (SD) had significant effects (p < 0.05) on CP and ash contents of the CDF, however there were no significant effects (p > 0.05) due to (CT) and (SD) on CF and nutritive value. High retention value (> 80%) for nitrogen was reported for the treated CDF, immediately after opening the incubated material (zero SD). However, nitrogen retention decreased with increasing (SD) to 67% after one month (SD) but tended to stay at a fairly constant level of 67% until 3 months of storage. In experiment 2, the feeding value of treated CDF was evaluated in comparison to Rhodes grass hay, using growing goats and sheep. A $4{\times}2$ factorial design was used (Four roughage sources were used : Rhodes grass hay, untreated CDF, urea-treated CDF and CDF treated with urea + DS with sheep and goats as two animal species, using three animals / treatment). Untreated CDF had a similar feeding value to Rhodes grass hay. However treatment of CDF with urea alone or with urea + DS depressed animal performance of both goats and sheep, apparently due to depression of feed intake (appetite). Feeding untreated CDF decreased feeding cost by 29% and cost/kg gain by 23%. CDF showed a good potential as a cheap local roughage and emergency feed for ruminants in the Sultanate.

Background: Low back pain secondary to discopathy is a common pain disorder. Multiple minimally invasive therapeutic modalities have been proposed; however, to date no study has compared percutaneous laser disc decompression (PLDD) with intradiscal injection of radiopaque gelified ethanol (DiscoGel^®). We are introducing the first study on patient-reported outcomes of DiscoGel^® vs. PLDD for radiculopathy. Methods: Seventy-two patients were randomly selected from either a previous strategy of PLDD or DiscoGel^®, which had been performed in our center during 2016-2017. Participants were asked about their numeric rating scale (NRS) scores, Oswestry disability index (ODI) scores, and progression to secondary treatment. Results: The mean NRS scores in the total cohort before intervention was 8.0, and was reduced to 4.3 in the DiscoGel^® group and 4.2 in the PLDD group after 12 months, which was statistically significant. The mean ODI score before intervention was 81.25% which was reduced to 41.14% in the DiscoGel^® group and 52.86% in the PLDD group after 12 months, which was statistically significant. Between-group comparison of NRS scores after two follow-ups were not statistically different (P = 0.62) but the ODI score in DiscoGel^® was statistically lower (P = 0.001). Six cases (16.67%) from each group reported undergoing surgery after the follow-up period which was not statistically different. Conclusions: Both techniques were equivalent in pain reduction but DiscoGel^® had a greater effect on decreasing disability after 12 months, although the rate of progression to secondary treatments and/or surgery was almost equal in the two groups.

Background: To evaluate the relative effectiveness of different treatments of hepatocellular carcinoma (HCC) via the hepatic artery. Materials and Methods: The study sample group consisted of 418 patients who were randomly selected from 2008 to 2012 with a first diagnosis of HCC and treated with transcatheter arterial chemoembolization (TACE) or without (TAE) chemotherapy or transcatheter arterial infusion (TAI). We collected data including tumor size preoperative and one month thereafter to compare change in areas across the three groups, along with various laboratory indexes for comparison. Results: The overall average change of areas was $240.8{\pm}72.1mm^2$. In the three groups it was $265.0{\pm}58.0mm^2$ vs. $250.5{\pm}51.9mm^2$ vs. $123.7{\pm}26.2mm^2$. In groups TACE and TAE values were larger than in group TAI (p<0.01), but the difference between the two was not statistically significant (p= 0.191). Additionally, U/L change of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in groups TACE and TAE was greater than in the TAI cases ($24.0{\pm}13.5$ vs. $20.9{\pm}12.1$ vs. $5.47{\pm}8.20$ and $25.6{\pm}13.5$ vs.$23.2{\pm}12.28$ vs.$5.48{\pm}14.3$) on the preoperative day and two days thereafter (p<0.01). Between the two groups there was no significant cariation (p= 0.320 and p= 0.609). However, the AST and ALT recovered to normal levels one month later on therapy with liver protecting drugs. Conclusion: The groups TACE and TAE demonstrated more effective reduction of tumor size than group TAI. While lipiodol caused acute liver function damage, this proved reversible.

A study was made on the chemical treatment of silica and silane coupling agents, bistriethox ysilylpropyltetrasulfide(Si 69) and ${\gamma}$-mercaptopropyltrimethoxy silane (MPS) for reinforcement of silica formulation. The effects of chemical treatment method and the most popular two coupling agents were examined. The results clearly indicate that the wet method, coupling agent is combined chemically with the silica prior to mixing, has more dispersion, wetting ability, dynamic properties and stability than the dry method, coupling agent is premixed directly with the silica. The mixing was done using a bench-type kneader having two mixing cam and a two-roll mill, under approximately similar conditions. The physical properties of SBR vulcanizates give rise to marked improvements by addition of Si 69 and MPS in comparison with without silane coupling agents. The optimum amount of Si 69 and MPS was 2 w/w% by experiments in the dry method but was 4 w/w% by EA and TGA analysis in the wet method.
