We evaluated whether group locomotor imagery training-combined knowledge of performance (KP) lead to improvements in gait function in community dwelling individuals with chronic stroke. Ten adults who had suffered a hemiparetic stroke at least 6 months earlier participated in group locomotor imagery training-combined KP for 5 weeks, twice per week, with 2 h intensive training. Dynamic gait index scores increased significantly after the group locomotor imagery training-combined KP. However, times for the timed up-and-go test did not improve significantly after the training. Group locomotor imagery training-combined KP may be a useful option for the relearning of gait performance for community dwelling individuals with chronic hemiparetic stroke.

국가차원의 신 재생에너지 활성화 방안에 따라 지자체 등의 분산전원 시실계획이 점차 증가하고 있으나, 아직 우리나라에서는 분산전원의 배전계통 연계에 대한 체계적인 기술지침이 초기 단계에 있거나 제정 중에 있어서, 계통 연계와 관련하여 발전사업자와 전력회사간의 이해가 상충되는 등 문제점이 발생되고 있다. 또한, 대규모 분산전원 단지의 도입이 이루어지고 있으나, 이에 대한 기술적인 평가방안이나 해석 방법이 구체적으로 제시되어 있지 않아, 설치자(시도 및 지자체)와 운용자(한전의 배전지사/지점)들은 많은 혼돈과 어려움을 겪고 있는 실정이다. 따라서 본 논문에서는 태양광, 풍력 등의 분산전원이 배전계통에 도입되는 경우, 연계에 대한 기술적인적합여부를 종합적으로 평가 할 수 있도록 분산전원 연계판정 시뮬레이션 시스템을 연구하였다. 즉, 구체적으로는 전력용량, 전기방식, 역률, 뱅크 역 조류, 상시전압변동, 순시전압변동, 플리커, 단락용량, 연계가능용량 등이며, 이들 항목을 계통연계 가이드라인과 평가 알고리즘에 의하여 연계 적합 여부를 판단해 주는 시스템이다.

본 논문에서는 PID 제어기의 이득 동조를 위한 퍼지 제어기를 제안한다. 제안한 제어기는 PID 제어기의 크리스퍼 출력 오차를 그대로 사용하지 않는 전단 퍼지화기에서 추론단계는 갖지만 Rule Table은 갖지 않는 특징이 있으며, 출력 소속 함수에 두 변수의 관계와 범위를 이용 도식화된 영역에서 비퍼지화 시킨 비선형 출력값을 PID 계수에 부가하는 새로운 Fuzzy PID 제어기를 제안한다. 여기서 Kp, Kd 계수의 최대, 최소 범위를 설정하여 퍼지추론에 의해 새로운 Kp, Kd 계수론 구한다. Ki 계수는 Ziegler-Nichols 동조 규칙을 사용하여 구하였고, 제안한 제어기는 유압서보모터 제어시스템에 의해 실험하였으며 실험결과 양호한 제어특성을 통해 원하는 결과를 얻을 수 있었다.

Kisspeptins (KPs) encoded by the KiSS-1 gene are C-terminally amidated peptide products, including KP-10, KP-13, KP-14 and KP-54, which are endogenous agonists for the G-protein coupled receptor-54 (GPR54). Functional analyses have demonstrated fundamental roles of KiSS-1 in whole body homeostasis including sexual differentiation of brain, action on sex steroids and metabolic regulation of fertility essential for human puberty and maintenance of adult reproduction. In addition, intensive recent investigations have provided substantial evidence suggesting roles of Kisspeptin signalling via its receptor GPR54 in the suppression of metastasis with a variety of cancers. The present review highlights the latest studies regarding the role of Kisspeptins and the KiSS-1 gene in tumor progression and also suggests targeting the KiSS-1/GPR54 system may represent a novel therapeutic approach for cancers. Further investigations are essential to elucidate the complex pathways regulated by the Kisspeptins and how these pathways might be involved in the suppression of metastasis across a range of cancers.

This paper is studied on the effect of TiAlN coated Ball End Mill and MQL(Minimum Quantity Lubrication) cutting condition on cutting characteristic of high hardness steels. KP4 steels[HRC32] and STD11[HRC60] heat treated steels were used as the workpiece and WC-Co ball end mill and single and multi layer TiAlN coated ball end mill were utilized in the cutting tests. MQL device was used to spray botanical oil coolant. Result showed that TiAlN coated ball end mill were increased the cutting length than WC-Co ball end mill in the cutting speed[$245{\sim}320m/min$] about $2.3{\sim}5.7$ times for KP4 steels and about $2.5{\sim}4.3$ times far STD11 heat treated steels. The multi layer TiAlN coated ball end mill is good for KP4 steels than single layer coated.

Purpose: This study compared the walking ability of chronic stroke patients following either treadmill training with knowledge of the result (KR group) or treadmill training with knowledge of the performance (KP group). Methods: Nineteen patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a KR group (10 patients) and a KP group (9 patients). They received 30 minutes of neuro-developmental therapy and treadmill training 30 minutes, five times a week for three weeks. The gait parameters were measured before and after training using the Optogait system. Results: After the training periods, the KR group showed significant improvement in gait speed, cadence, step length of the unaffected limb, stance time of the affected limb, and functional gait assessment compared to the KP group (p<0.05). Conclusion: The results showed that treadmill training with KR was more effective in improving the gait speed and cadence, step length of the unaffected limb, stance time of the affected limb, and functional gait ability than the treadmill training with KP. Therefore, to improve the walking ability of stroke patients, it is necessary to consider treadmill training with KR. If it can be combined with conventional neurological physiotherapy, it would be an effective rehabilitation for stroke patients.

A bacteium, KP-6408, capable of hydrolyzing fibrin was isolated from Chungkook-jang, which was possibly identified as a strain of Bacillus sp. The effects of culture condition and medium composition on the enzyme production were investigated. Among nitrogen sources tested, yeast extract was the most effective for the enzyme production, and the level of the concentration for the optimal enzyme production was 0.2%(w/v). For carbon sources, glucose was the best for the enzyme production with the level of 2.0%(w/v). The enzyme was maximally produced by cultivating the enzyme production with the level of 2.0%(w/v). The enzyme was maximally produced by cultivating the organism at the liquid medium of the initial pH 8.0 and temperature of 4$0^{\circ}C$. In Chungkook-jang fermentation, the enzyme was maximally produced when incubated at 35$^{\circ}C$ for 24 hrs using soybean as a solid medium. The addition of various rice starch to the soybean in Chungkook-jang fermentation lowered the enzyme production.
