Biofloc technology (BFT) systems provides an additional protein source for fish by converting waste in microbial flocs. Therefore, we aimed to determine the difference in the protein levels of the diet of Far Eastern catfish Silurus asotus reared in BFT and FW systems. We applied a two-way (six protein levels × two aquaculture systems) ANOVA design. We formulated six experimental diets to contain different protein levels (CPs)- 20%, 25%, 30%, 35%, 40% and 45%-referred to as the CP20, CP25, CP30, CP35, CP40 and CP45 diets, respectively. We randomly distributed 900 fish into 36 (18 each for BFT and FW), 300 L tanks (25 fish/tank) with three replications of each diet for 4 weeks. The weight gain (WG) and specific growth rate (SGR) considerably improved as the dietary protein level increased in the formulated diets. The BFT fish showed higher growth performance with any experimental diet than the FW fish. The growth performance of the fish fed the BFT-CP35 diet was higher than that of the fish fed the FW-CP45 diet. In conclusion, the cultivation of Far Eastern catfish (S. asotus) in BFTs can be carried out under reduced dietary protein levels.

Purpose: We investigated the effect of far-infrared radiating products on cold hypersensitivity of lower limbs using CST. Methods: 7 patients with cold hypersensitivity of lower limbs were investigated in this study. Exclusive criteria was skin diseases, spinal nervous disease and external wounds. They were asked to answer the VAS of cold hypersensitivity at baseline and after 3 weeks. We measured temperature of lower limbs with Spectrum 9000 MB (Dorex Inc, USA). We performed cold stress test (CST) by 3 thermographic observation using DITI : 1st was taken after 15 minutes resting at $25^{\circ}C$, the 2nd was immediately taken after 1 minute soak in $20^{\circ}C$ water, the 3rd was taken at 15 minutes after soak. We performed 3 times of CST : 1st CST was perfomed at baseline, 2nd CST was perfomred after 1 week and just observation, 3rd CST was performed after 1 week using far-infrared radiating products (lasner, UMT, Korea). Results: After using products, temperature of foot incresed more than thigh area, but there was no significance. There was no statistical difference of VAS, change of temperature and CST between before and after using far-infrared radiating products. Conclusion: There was no statistical effect of far-infrared radiating products on change of temperature of lower limbs.

Objective : To prospectively assess the diagnostic and clinical value of a new technique (3-tesla magnetic resonance myelography, 3T MRM) as compared to computed tomographic discography (disco-CT) in patients with far lateral disc herniation. Methods : We evaluated 3T MRM and disco-CT of 25 patients, whom we suspected of suffering from far lateral disc herniation. Using an assessment scale, 4 observers examined independently both 3T MRM and disco-CT images. We analyzed observer agreement and the accentuation of each image. Results : We found complete matching, and observer agreement, between high resolution images of 3T MRM and disco-CT for diagnosing far lateral disc herniation. Conclusion : We think noninvasive 3T MRM is an appropriate diagnostic tool for far lateral disc herniation as compared to disco-CT.

일반적으로 조류충돌 안전성 입증에 대한 규정은 고정익 항공기 중 FAR Part 23급 커뮤터 및 FAR Part 25급 민간항공기 부류의 항공기에 국한되어 적용되고 있다. 이는 상대적으로 낮은 비행속력과 주로 개인용 항공기로의 활용 등의 이유로 조류 충돌에 대한 위험성이 낮게 평가되었기 때문이다. 하지만 최근의 지점 간 운송을 목적으로 하는 Air-Taxi 등의 수요 증가로 인한 소형항공기 운항시간 증가 예측과 급격한 수요의 VLJ(Very Light Jet)등은 FAR Part 23급 Normal, Utility급 항공기의 조류 충돌 안전성에 대한 규정 적용 및 안전성 향상에 대한 필요성을 증가시키고 있다. 본 연구에서는 외연적 유한요소 해석을 이용한 소형항공기 주익에 대한 조류 충돌 안전성 평가와 Crushable Foam을 적용한 안전성 향상방안을 제시하고 있다.

This study is investigation of clinical statistics toward to old patients of 164 persons over full 65 years old to go to hospital in 5 internal medicine department of the Dongguk University Oriental Medicine Hospital for full one year from 1995. 8 to 1996. 7. The results are followings ; 1. The ratio of male and female was 1:1.6, and in offspring figures five persons or more(60.3%) was most. A couple(32.3%) was extremely much in residing forms, but in accordance to sexual distinction in male a couple(51.7%), in female solitude(31.0%) and an eldest son couple(30.0%) was far much. 2. An attack time, first cure was most in western hospital(59.2%), 81.1% of them desired western-oriental medicine cooperation, in a medical fee charging, themselves(50.7%) were far much, and most were affirmative(76.8%) against aging prevention of restorative. 3. Main diseases were cerebral nerve(41.5%) and circulatory system(25.6%), hypertention (23.8%, 9.8%) was most in complication and the past. In defecation constipation(31.7%), in urination frequence(46.7%) was far much. 4. In preventive measures of diseases invigorant(25.6%) and nothing(24.3%) was far much and in a person tending the sick a mate in male(16.7%), a son in female(13.0%) was extremely much. 5.

본 연구는 유럽의회 선거에서 극우정당들이 거둔 성과를 논하거나 지지세 추이를 확인하기 위해서 유럽의회 정치그룹이 확보한 의석수를 중심으로 분석하는 기존의 방법을 지양하고, 그 대신 EU 회원국들 국내 정치에서의 극우 동종정당(far-right party family) 분류를 통하여 그들이 유럽의회 선거에서 거둔 의석수를 합산하는 방식으로 분석한다. 이러한 극우 동종정당에 기반한 선거 결과 분석이 필요한 이유는 두 가지이다. 첫째로 유럽의회 선거에서 선출된 극우성향의 유럽의회의원들 중 일부는 극우성향의 정치그룹에 가입하지 않기 때문이며, 둘째로 극우성향으로 분류되는 일부 정치그룹의 경우에 소속 의원들의 성향이 균질하지 않아 오히려 다수는 중도우파성향의 의원들로 구성된 경우도 있기 때문이다. 이러한 문제의식에서 출발한 본 연구는 구체적으로 2019년 유럽의회 선거에서 극우정당이 거둔 성과를 극우 동종정당 분류에 기반하여 분석해 보았다. 그 결과, 유럽의회 정치그룹이 확보한 의석수 중심 분석에 기반하여 극우정당들이 이번 유럽의회 선거에서 그다지 약진하지 못했다는 평가를 내린 서구 주요 언론들의 분석에 명확한 한계가 있음을 확인할 수 있었다. 극우 동종정당 분류에 기반한 선거 결과 분석에 따르면, 2019년 유럽의회 선거에서 극우정당들이 확보한 의석수는 선거 전 여론조사 결과를 오히려 크게 상회하는 것으로 나타났음은 물론, 2014년 유럽의회 선거와 비교하더라도 극우정당들의 의석수가 큰 폭으로 증가한 것인 바, 본 연구는 2019년 유럽의회 선거에서 극우정당은 크게 약진했다고 평가하는 것이 타당하다고 주장한다.

Object The purpose of this study is to evaluate the effect of far-infrared (FIR) therapy on weight loss. Method Thirty five participants (BMI ${\geq}25kg/m^2$) were recruited. Body weight, Waist circumference (WC), Bio Impedance Analysis (BIA), abdominal fat Computer Tomography (CT) scanning were evaluated. Results of 25 women were analyzed. Result After 6 weeks of FIR therapy, there was significant efficacy on obese women in body weight, WC, Body fat mass (BFM), and Visceral fat area (VFA). But there was no efficacy in Total fat area (TFA), and Subcutaneous fat area (SFA). Conclusion This study suggests that FIR therapy might be an effective way to promote weight and abdominal visceral fat loss in Korean obese women.
