This study was conducted to determine the effects of hempseed (H) on performance, carcass traits, and antioxidant activity in Japanese quail (Coturnix coturnix japonica). A total of 192 quail with seven-days old were divided into four experimental groups with four replicates. The treatments were; i) Control diet (C, no hempseed); ii) 5% hempseed in diet (H5); iii) 10% hempseed in diet (H10); and iv) 20% hempseed in diet (H20). The body weight (BW) and feed intake (FI) of quail was determined at 7, 21 and 42 d of age. At 42 d of age four quail were slaughtered and the carcass and internal organ traits were determined. Malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), nitric oxide (NO) and total protein were determined in the blood serum end of the experiment. The BW of the groups were not significant at 7 and 21 d, however in the 20% hempseed group BW decreased at 42 d (p<0.05). The FI and feed conversion ratio were not significant among the treatment groups. The carcass, liver, intestine and heart weight and their percentage to carcass were significantly differ in treatment groups (p<0.05). The serum MDA and NO decreased in hempseed addition (p <0.001). The serum SOD, CAT and GSH-Px were increased by hempseed supplementation (p<0.001). In conclusion, hempseed supplementation to quail diets may not improve quail performance traits but increase antioxidant activity in blood.

Objectives : To evaluate the evidence supporting the effectiveness of Chuna manual therapy for functional dyspepsia. Methods : We conducted search across the 3 electronic databases (Pubmed, CAJ and Oasis) to find all of randomized controlled clinical trials(RCTs) that used Chuna manual therapy as a treatment for functional dyspepsia. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : Thirteen RCTs met our inclusion criteria. The meta-analysis showed positive results for the use of Chuna manual therapy combined with medication treatments in terms of the efficacy rate when compared to medication treatments alone. Positive results were also obtained, in terms of the efficacy rate, when comparing Chuna manual therapy combined with medication plus specific electromagnetic therapy to medication treatments alone. Conclusions : Our systematic review found encouraging but limited evidence of Chuna manual therapy for functional dyspepsia. However, to obtain stronger evidence without the drawbacks of trial design and the quality of studies, we recommend sham-controlled RCTs or comparative effectiveness research to test the effectiveness of Chuna manual therapy.

The inclusion of a ductile steel bracing as means of repairing an earthquake-damaged bridge bent is evaluated and experimentally assessed for the purposes of restoring the damaged bent's strength and stiffness and further improving the energy dissipation capacity. The study is focused on substandard reinforced concrete multi-column bridge bents constructed in the 1950 to mid-1970 in the United States. These types of bents have numerous deficiencies making them susceptible to seismic damage. Large-scale experiments were used on a two-column reinforced concrete bent to impose considerable damage of the bent through increasing amplitude cyclic deformations. The damaged bent was then repaired by installing a ductile fuse steel brace in the form of a buckling-restrained brace in a diagonal configuration between the columns and using post-tensioned rods to strengthen the cap beam. The brace was secured to the bent using steel gusset plate brackets and post-installed adhesive anchors. The repaired bent was then subjected to increasing amplitude cyclic deformations to reassess the bent performance. A subassemblage test of a nominally identical steel brace was also conducted in an effort to quantify and isolate the ductile fuse behavior. The experimental data from these large-scale experiments were analyzed in terms of the hysteretic response, observed damage, internal member loads, as well as the overall stiffness and energy dissipation characteristics. The results of this study demonstrated the effectiveness of utilizing ductile steel bracing for restoring the bent and preventing further damage to the columns and cap beams while also improving the stiffness and energy dissipation characteristics.

Objective : This study aimed to investigate the changes and significance of microRNA155 levels in serum of patients with cerebral small vessel disease (CSVD). Methods : Thirty patients with CSVD who met the inclusion criteria were selected and divided into eight patients with lacunar infarction (LI) group and 22 patients with multiple lacunar infarction (MLI) combined with white matter lesions (WML) group according to the results of head magnetic resonance imaging (MRI). Thirty samples from healthy volunteers without abnormalities after head MRI examination were selected as the control group. The levels of serum microRNA155 in each group were determined by real-time polymerase chain reaction, and the correlation between microRNA155 in the serum of patients with CSVD and the increase of imaging lesions was analyzed by Spearman correlation analysis. Results : Compared with the control group, the serum microRNA155 level in the LI group, MLI combined with WML group increased, the difference was statistically significant (p<0.05); serum microRNA155 level was positively correlated with the increase of imaging lesions (p<0.05). Conclusion : The change of serum microRNA155 level in patients with CSVD may be one of its self-protection mechanisms, and the intensity of this self-protection mechanism is positively correlated with the number of CSVD lesions.

Purpose: This study aimed to define the relationship among self-care, symptom experiences, and health-related quality of life(HRQoL) according to the severity of disease in chronic obstructive pulmonary disease(COPD) patients. Methods: The participants, 195 COPD patients, were recruited at a pulmonology clinic of a universityaffiliated medical center in B metropolitan city. Inclusion criteria were patients who were diagnosed as COPD and had less than 0.7 of $FEV_1$/FVC(Forced Expiratory Volume for 1 second/Forced Vital Capacity) ratio. The severity was classified with GOLD(Global initiative for Obstructive Lung Disease) stages, $FEV_1%$ predicted value from mild to very severe. The data were gathered by the medical records and self-reported questionnaires. Results: The self-care, symptom experience, and HRQoL were all significantly different by COPD severity based on pulmonary function(p<.05). There were significant moderate negative relationships between symptom experiences and self-care(r=-.54, p<.001) and between symptom experiences and HRQoL(r=-.64, p<.001). There was a moderate positive correlation between self-care and HRQoL(r=.63, p<.001). Conclusion: It suggests that the assessment of disease severity based on pulmonary function and subjective symptom experience in patients with COPD may be a key component to develop a tailored self-management program and to improve their quality of life.

The objectiveness of this study was to evaluate whether low-viscosity composite can bond effectively to dentin surface without bonding resin. The low-viscosity composites being 50wt% filler content were made by the inclusion of bonding resin of two self-etching systems(Cleafil SE Bond, Unifil Bond) varied with contents as 0, 10, 20, 30, 40, 50wt%. Exposed dentin surfaces of extracted 3rd molars are used. Dentin bond strengths were measured. The tests were carried out with a micro-shear device placed testing machine at a CHS of 1mm/min after a low-viscosity composite was filled into an iris cut from micro tygon tubing with internal diameter approximately 0.8mm and height of 1.0mm. 1 Flexural strength and modulus was increased with the addition of bonding resin. 2. Micro-shear bond strength to dentin was improved according to content of bonding resin irrespective of applying or not bonding resin in bonding procedure, and that of Clearfil SE Bond groups was higher than Unifil Bond. 3. There were no significant difference whether use of each bonding resin in bonding procedure for S-40, S-50, U-50(p＞0.05). 4. In SEM examination, resin was well infiltrated into dentin after primed with self-etching primer only for S-50 and U-50 in spite of the formation of thinner hybrid layer. Low viscosity composite including some functional monomer may be used as dentin bonding resin without an intermediary bonding agent. It makes a simplified bonding procedure and foresees the possibility of self-adhesive restorative material.

Purpose: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. Methods: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. Results: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. Conclusion: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

In this paper, the large signal unified model is established for H4O GaAs pHEMT of GEC-Marconi using modified Curtice model. This unified model includes DC characteristic, small signal, and noise characteristic as various bias. Particularly, the model can simply and physically explain trans-conductance $(g_m)$ of pHEMT using modified Curtice model, and can tell the difference $g_m$, $R_ds$ at DC and these at AC through inclusion of internal RF-choke. The results of the established model built up using SDD in HP-Eessof show good agreement to the S/W measured data in DC, small signal, and noise characteristic. This model can also be applied to various computer aided analysis, such as linear simulation, 1-tone harmonic balance simulation, and multi-tone harmonic balance simulation, so the LNA(Low Noise Amplifier), oscillator, and mixer design has been shown using this model library.

Objective : To find a treatment strategy, this study aimed to review and compare the clinical studies of Korea, China, and Japan on traditional medicine treatment for Behcet's disease. Method : Literature searches were performed on six databases in each country and English databases, such as OASIS, KoreanTK, CNKI, J-STAGE, PubMed, and Cochrane CENTRAL. In addition, using the limited keywords, the area was restricted to traditional medicine treatment, but the period was not limited. Studies were categorized according to the study design and we analyzed the difference of treatment among three countries. Results : One hundred and forty-one clinical studies met our inclusion criteria: 11 studies in Korea, 15 in Japan, 115 in China. Randomized controlled trials (RCT) have increased in China, however, no RCT was reported in Korea and Japan. The method of treatment was mainly traditional herbal medicine in all the three countries, but there were significant differences in the field of syndrome identification and prescription among countries. The studies in China made use of most various treatment modalities and reported the highest effectiveness. Conclusion : Traditional medicine treatment showed a considerable effect for improving various symptoms of Behcet's disease. However, more research for answering the safety and well-designed studies considering characteristics of Behcet's disease should be performed to evaluate the effectiveness of traditional medicine treatment objectively in the future.

Background: The aim of this study was to review clinical efficacy of acupuncture treatment of mild cognitive impairment. Methods: Randomized controlled trials that performed acupuncture treatment for mild cognitive impairment were retrieved from 6 online databases (PubMed, Cochrane Library, EMBASE, CNKI, NDSL, OASIS) on September $30^{th}$, 2018. Studies were selected according to inclusion and exclusion criteria, and were reviewed by Risk of Bias assessment. Results: In total, 21 studies were included in this review. All studies were Chinese (19 studies published in Chinese and 2 in English). The sample size, 50 to 100, and the number of treatment times, 20 to 30, were the largest range in all studies. The most treatments performed was 30. The longest treatment period was 56 days, which accounted for 33% of the studies. The most frequently used evaluation index was the Mini Mental State Examination followed by the Montreal Cognitive Assessment, each used 17 times and 15 times, respectively. The most frequently used acupoints were GV20, EX-HN1, GB20, and GV24, which accounted for 47% of total number of acupoints used. In 48% of the studies, needle retention time was 30 minutes. Western medicine treatment was the most common control group. Most studies reported that the intervention group was statistically significantly different to the control group. Conclusion: These results suggest that acupuncture for mild cognitive impairment was effective. However, it is difficult to confirm this conclusion because the quality of most of these studies were of low quality.
