중력분을 이용하여 제면한 후 가압가열, microwave 및 가 압가열과 microwave 병행 처리한 후, 생면 및 삶은 면의 품질 에 미치는 영향에 대하여 알아보았다. 생면의 pH는 microwave 1 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았 으며, 수분 함량은 autoclave 50 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았고, 그 외의 처리구에서는 모두 수분 함량이 감소함을 확인하였다. 면의 색도 측정 결과는 명 도는 무처리구에 비해 모든 처리구에서 감소하였으며, 적색 도는 microwave 1 min 처리구는 감소한 반면, 나머지 처리구 는 증가하였다. 황색도는 autoclave 50 min 처리구와 autoclave 50 min/microwave 1 min 병행 처리구에서 증가한 반면, 나머 지 물리적 처리구에서는 감소하였다. 삶은 면의 색도에서는 명도, 적색도, 황색도 모두에서 무처리구에 비하여 물리적 처 리구에서 증가한 값을 나타내었다. 물성 측정 결과는 경도, 부착성, 응집성, 검성, 복원성에서 무처리구와 비교시 microwave 1 min 처리구는 유의적으로 감소하였으며, 그 외 처리구에서 는 유의적으로 증가한 값을 나타내었다. 탄력성과 전단력은 모든 처리구에서 유의적으로 증가하였으며, 인장력은 가압가 열 30 min 처리구와 무처리구가 유의적인 차이를 보이지 않았으나, 나머지 물리적 처리구에서는 유의적으로 증가하였다. 관능 평가 결과는 생면의 경우 색 항목에서 물리적 처리구들 이 유의적으로 낮은 점수를 받았다. 맛, 질감, 향 항목에서는 무처리구와 물리적 처리구간 유의적 차이를 보이지 않았다. 전체적인 기호도에서는 microwave 1 min 처리구가 가장 높은 점수를 얻었으며, 가압가열(50 min)과 microwave(1 min) 병행 처리구는 무처리구와 비슷한 점수를 얻었다. 따라서 제면 후 가압가열 및 microwave 처리가 생면 및 삶은 면에 있어서 색 과 질감 항목을 보완, 개선시킨다면 알러겐성이 저감화된 면 을 제품화하는데 적합할 것으로 사료되어진다.

Aflatoxins produced by Aspergillus spp. are recognized as a major concern in animal and human health. In pigs, ingestion of aflatoxin-contaminated feeds causes immunosuppression, hepatotoxicosis and poor feed efficiency. In this study, we screened the contaminated level of aflatoxins in 449 pig feeds from 12 swine farms in Korea. For rapid and efficient screening of aflatoxins in pig feeds we evaluated the feasibility of three commercial ELISA kits for the screening of aflatoxins in pig feeds. Twenty-nine pig feed samples were examined for total aflatoxins using three ELISA kits, simultaneously. From three repetitions of each assay, the average intra-assay precisions and the average inter-assay precisions expressed as coefficient of variation (CV, %) for VeratoxⓇ Quantitative Aflatoxin test were 6.90 and 12.29, respectively. A statistical comparison of the results between HPLC and ELISAs showed that the correlation coefficient values for VeratoxⓇ was 0.96. The results demonstrated that we can apply the VeratoxⓇ Quantitative Aflatoxin test for the detection of aflatoxins in pig feed from the field. The screening of field samples with this ELISA kit showed that 11 out of 265 pig feeds for growers and weaners were contaminated with total aflatoxin levels exceeding 10 ppb, maximum tolerable limits for their compound feeds and the aflatoxins levels of remaining 184 pig feeds for other age groups of pigs were confirmed as below 20 ppb. The results from the screening indicated overall low levels of aflatoxins contamination in pig feeds.

Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis and autoimmune polyradiculoneuropathy. Campylobacter jejuni is the most commonly identified infectious trigger for GBS. A sialic-acid containing lipopolysaccharide (LPS) of Campylobacter is thought to be involved in the triggering of GBS. The galE (UDPgalactoset- epimerase) gene of Campylobacter spp. is involved in the synthesis of LPS. In this study, we detected the galE gene in Campylobacter spp. responsible for triggering the onset of GBS. The PCR assay detected the presence of the gene in 14 of the 25 (56%) Campylobacter isolates from domestic chicken, 20 of the 28 (71.4%) Campylobacter isolates from imported chicken and 50 of the 51 (98%) Campylobacter isolates from human clinical samples. Also, the specific 497-bp region of galE sequence in Campylobacters responsible for triggering the onset of GBS was amplified from GBS patient. These results could provide evidence of the first GBS-related C. jejuni infection in Korea.

Wearable robots are receiving great attention from the public, as well as researchers, because its motivation is to improve the quality of lives of people. Above all, complete paraplegic patients due to spinal cord injury (SCI) might be the most adequate target users of the wearable robots, because they definitely need physical assistance due to the complete loss of muscular strength and sensory functions. Furthermore, the medical care of complete paraplegics by using the wearable robots have significantly reduced the mortality rate and improved the life expectancy. The requirements of the wearable robot for complete paraplegics are actuation torque, locomotion speed, wearing sensation, robust gait stability, safety, and practicality (i.e., size, volume, weight, and energy efficiency). A WalkON Suit is the wearable robot that has satisfied the requirements of the wearable robot for complete paraplegics and participated in the powered exoskeleton race of Cybathlon 2016. In this paper, configuration of the WalkON Suit, human-machine interface, gait pattern, control algorithm, and evaluation results are introduced.

In this paper, shear strain dependence of high hardness laminated rubber bearings were studied through tests. The shear strain dependency test is considered the changes by increase the shear strain by 50%, 100% and 150% based on 100% of total rubber thickness. As the test results shear strain increases were identified a tendency to decrease the shear stiffness.

Has been widely applied in order to minimize damage such as earthquake engineering and building structures, because the economics and efficiency is relatively good seismic isolators. Are widely used from the seismic isolation bearings LRB inhibits excessive displacement occurs on foot by improving the damping capacity of the seismic isolation structure with the flexibility of the rubber bearings during the earthquake, and secure the safety by reducing the seismic forces. The flexible backing is required unlike the conventional one for civil engineering, considering the characteristics of the seismic isolation building plate is the upper structure. The aim of this study was to perform a compression and shear tests to validate the performance limits of the performance of seismic isolation bearings supporting the main features of the structure and lateral displacement.
