프랑스 CEA 실험장치인 BETHSY 실험설비에서 수행된 부분충수 운전에 대한 실험인 6.9c 실험에 대한 MELCOR 1.8.3 의 평가를 수행하였다. 이 연구는 OECD/NEA 국제공동연구인 ISP-38 로 수행되었다. 평가결과, MELCOR 1.8.3 은 부분충수운전시 잔열제거계통 상실에 대한 예측능력이 있고 원자로 냉각재계통압력, 노심수위 등 전반적으로 거동을 잘 모의하고 있다고 판단되었다. 그러나 민감도 분석에서 도출된 결론에 의하여 상간의 운동량 전달 및 Liquid Entrainment모델에 있어서 개선 필요성이 있는 것으로 평가되었다.

Objective : This study aimed to confirm the possibility of the clinical application of oral motor facilitation technique (OMFT) protocol and neuromuscular electrical stimulation (NMES) in patients with Wallenberg syndrome. Methods : One patient with Wallenberg syndrome was treated with OMFT and NMES applied 40 times each, 5 days a week, twice a day for 4 weeks. The Comprehensive Oral-Facial Function Scale (COFFS), Korean-Mann Swallowing Ability Assessment (K-MASA), and Penetration-Aspiration Scale (PAS) were used to compare the changes before and after the intervention. Data analysis was used to compare the score changes before and after the intervention. Results : Orofacial function and swallowing ability improved after the intervention in the individual who participated in this study. Among oral motor functions, relatively greater functional improvement was observed in tongue movement compared to other functions, which was evaluated to the extent that pharyngeal swallowing was possible. Conclusions : Early swallowing rehabilitation using systematic OMFT and NMES of exercise intensity confirmed the possibility of improving oral motor function and dysphagia. In the future, complementary studies on the effects of interventions applying the OMFT and NMES will be needed.

운동선수를 평가하는 기준은 다양하지만, 그 가운데에서도 선수가 가진 신체 혹은, 공격과 수비에 대한 균형능력은 어느 종목에서나 공통적인 기준이 된다. 정보보호 분야에서도 이 균형을 얘기하는 사람들이 많이 있다. 규제와 자율, 보안성과 가용성. 이 모든 것을 적절히 활용하는 능력은 균형감각 없이는 어렵기 때문이다. 자유분방하기로 소문난 웹 서비스 업체의 구성원들 사이에서 기업의 보안을 책임져야 하는 네오위즈 게임즈 보안팀도 그런 균형감각에서 뛰어난 모습을 보여준다.

이 연구의 목적은 발목관절의 발등굽힘 가동범위에 따라 동적 균형능력을 평가하는 Y-Balance Test와의 관계를 규명하고자 하였다. 이 연구 결과 HADR군에서 PLRD(P<.05)와 CS(P<.01)에서 유의한 차이가 나타났으며, 발목관절 발등 굽힘의 가동범위와 뒤안쪽 도달거리(PMRD), 뒤가쪽 도달거리(PLRD) 및 종합점수(CS)만 중등도의 유의한 상관관계가 나타났다. 따라서 발목관절 발등굽힘의 감소는 균형능력 능력을 감소와 관련이 있으며 축구선수의 손상의 예방하기 위해서는 정기적인 발목 관절가동범위를 평가가 필요한 것으로 생각된다.

The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. This research was planned to apply Artesmisia capillaris, which is one of the most widely used oriental medicinal resource into beverages, and to evaluate the validity and the nutrients of the developed beverage with Artemisia capillaris. Following this plan, we analyzed contents of the general nutritional composition, mineral and amino acid contents. And to evaluate the improvement of blood circulation and the ability to recover from fatigue, we had a group of athletes to regularly take the beverage before and after exercise and checked the heart rates, and blood components before exercise and after exercise. Brix, pH and titratable acidity of develoued drink were 9.2%, 4.4 and 0.04%, respectively. The approximate nutritional composition of beverage was carbohydrate, 2.70%, crude protein, 6.00%, crude ash, 0.20%, and crude fat, 0.10%. And developed beverage contained essential amono acids and minerals (p, Ca, K, Na, Fe, Mn, Zn). Heart rates, lactic acid, glucose, creatinine, LDH, GOT, GPT and lipid concentratios in blood were decreased after taking the beverage with Artemisia capillaris for 6 weeks, both in stable condition and after exercise. Since the athletes who participated In our research were doing aerobic exercise regularly, we judged that this result was formed not only by aerobic exercise, but also by the function of developed beverage with Artemisia capillaris the athletes took for 6 weeks. We believe that taking the beverage regularly will help the improvement of the public health and the athleticism of the athletes. We hope that this result will be used as the basic resource in developing of the beverage with Artemisia capillaris in the near future.

The purpose of this study was to investigate the effects of the Otago exercise program on physical function and risk of falling in elderly who have experienced falls. Thirty-six elderly people who had experienced falls more than once were randomly classified into an experimental group and control group. Each group exercised 30 minutes three times per week for a total of 8 weeks. Measurements were made using Tetrax to assess risk of falls. In addition, to measure physical function, static balance was measured using Biorescue, dynamic balance was measured using TUG, walking ability was measured using 10 MWT, and lower extremity strength was measured using FTSST. A paired t-test was conducted to verify the difference between before and after exercise in each group, and an independent t-test was performed for comparison between the groups. Regarding the experimental and control groups, static balance ability and dynamic balance ability increased significantly after exercise, and risk of falls decreased (p<.05). Lower extremity strength and gait ability increased significantly after exercise only in the experimental group (p<.05). Based on these results, the Otago exercise program is effective in improving physical function and reducing risk of falls in elderly people who have experienced falls.

The present study was conducted to evaluate the effects of extract from Eriobotrya japonica leaves (EJE) on cognitive impairment induced by scopolamine, a muscarinic antagonist, in rats. Scopolamine injection (1 mg/kg, i.p.) impaired performance in rats in the passive avoidance test as well as in water maze test and severely reduced cholinergic system reactivity, as indicated by reduced acetylcholine levels and increased acetylcholinesterase activity. Daily administration of EJE significantly increased step-through latency in the passive avoidance test, reduced escape latency, and increased time spent in the platform quadrant in the Morris water maze test. EJE protected against scopolamine-induced cholinergic system deficit, including reduced acetylcholine levels and increased acetylcholinesterase activity in whole brain homogenates. These results suggest that EJE provides a significant anti-amnesic effect against scopolamine-induced cholinergic system deficits and cognitive impairment.

해상 상태의 변화는 어선에 탑승하고 있는 선원들의 피로도, 인지능력, 활동성 및 숙련도 변화 등과 같은 현상이 발생한다. 어선의 동요가 심해지면 특히, 멀미 증상이 발생하게 되며 개개인의 작업수행 능력이 급격히 떨어진다. 본 연구에서는 3톤급, 7톤급, 10톤급, 20톤급 어선을 대상으로 하여 파랑 중 운동 성능을 평가하여, 실해역 조건으로 어선의 선내 위치별 수직가속도 성분을 선체 운동 계산법을 통하여 계산하였다. 어선의 크기별 정박상태에서 수직가속도 스펙트럼을 사용한 멀미의 정도를 표시하였으며, MSI 계산은 입사파 방향 180도, 150도, 120도, 90도, 60도, 30도, 0도로 수행하였다. 그 결과 특정 주파수에서 입사파 방향에 따른 멀미의 가능성이 나타났다.

Information about regional wall motion obtained with gated $^{99m}Tc-MIBI$ SPECT was compared in 23 subjects(4 normals) to echocardiography or contrast left ventriculography. Gated SPECT study using 20-30 mCi $^{99m}Tc-MIBI$ were aquired lot 8 frames/RR interval (aqusition time=40min.) and processed with Cine Mode computer protocol. Regional wall motion was assessed by visual analysis. The concordance with echocardiography was 88% and with contrast ventriculography was 78%. We conclude that gated $^{99m}Tc-MIBI$ SPECT was effective in assessing the regional wall motion with the information of regional perfusion in one study.

The purpose of this study is to investigate the effects of aerobic exercise and probiotics ingestion on motor learning and body weight in female mice during adolescence. The subjects were divided into six groups of variables, such as non-exercise, moderate, high-intensity exercise, probiotics ingestion, and non-probiotics, and then treated for four weeks. The vertical grid test was conducted before and after the treatment to evaluate motor learning and bodyweight. The high-intensity exercise and probiotics ingestion group showed fastest up, rotation, and down rate than the non-exercise group (p<.001). Also, a group that treated exercise and probiotics tended to record speedier performance than those that performed the only exercise. Comparing weight changes, the weight gain of a group that performed only moderate-intensity exercise was higher than that of a non-probiotics and non-exercise group (p=.032). Taken together, aerobic exercise during adolescence can help improve motor learning, and more efficient motor learning can be achieved when combined with probiotics ingestion.
