Objective: The purpose of this study was to investigate questions and instructions for internal feedback effects on functional recovery and task performance while chronic stroke patients practised task-specific training. Method: Twenty-four chronic stroke patients were randomly divided into two groups; when patients performed same tasks, one was treated using questions and the other using instructions for internal feedback Both lasted 30 minutes, 5 times a week for 8 weeks. Outcome measures included Erasmus MC Modifications to the Nottingham Sensory Assessment (EmNSA), Measurement Properties of the Motor Evaluation Scale for Upper Extremity in Stroke patients (MESUPES), Chedoke Arm and Hand Activity Inventory (CAHAI), Korean version of Modified Barthel Index (K-MBI). Results: There were no significant differences between the two groups in EmNSA and K-MBI(p>.05). But, in MESUPES and CAHAI, there was significant difference between the two groups(p<.05). Conclusion: In this study, questions for internal feedback during task-specific training are more effective in improving upper extremity motor function and task performance than instructions for internal feedback.

The purpose of this study was to examine the effect of the upper limb nerve mobilization (ULNM) on functional recovery of upper extremity in hemiplegic patients following stroke. Twenty patients who had functional impairment on upper extremity were participated. Subjects were randomly divided into two groups: Control group (n=10) received traditional physical therapy only for 4 weeks; Experimental group (n=10) received ULNM treatment along with traditional physical therapy for the same period. Upper extremity functions were assessed by manual muscle test (MMT), modified Ashworth scale (MAS), and Fugl-Meyer assessment (FMA) before and after the treatment. In both experimental and control group, upper extremity functions were significantly improved in MMT (p<.01) and FMA (p<.01), however only experimental group showed significant improvement in FMA after the treatment (p<.05). Moreover, experimental group showed significantly greater improvement than control group in MMT (p<.05), MAS (p<.05), and FMA (p<.05). We conclude that the upper extremity functions is a useful additional therapeutic technique for the effective treatment of upper extremity deficits in hemiplegic patients.

The recent earthquake of Pohang (M5.4) and the Gyeongju earthquake (M5.8) suggested the possibility of a strong earthquake in Korea and reminded us that the Korea is no longer an earthquake-safe zone. In the disaster recovery stage in a disaster like an earthquake, the investigation of the damage situation and the safety assessment of the building serve to provide important information for the initial action such as establishment of the recovery strategy and rescue of the survivor. However, the research that depends on manpower can not cope with the difficulty of processing a large number of doses in a short time, and the expertise of the manpower must be taken into consideration, which may result in delayed initial action. In this study, we propose an rapid safety evaluation technique of building using unmanned aerial vehicle which evaluates the performance and safety of buildings by integrating conventional safety inspection method with unmanned aerial vehicle technology and developed evaluation method of each evaluation factor. In order to verify this, the buildings damaged by the earthquake in Pohang were checked and compared using this system. The results are consistent with the results of the existing emergency earthquake risk assessment. As a result, the possibility of checking the emergency safety using the unmanned aerial vehicle for the damaged structures in case of a large-scale disaster such as an earthquake was confirmed.

This paper discussed the assessment of hand of Tencel denim fabrics finished by enzymatic hydrolysis. The subjective hand and the preference of Tencel denim fabrics were evaluated using the developed scale. The factors affecting consumers taste for Tencel denim fabrics were analyzed by statistics using SAS program. Also, the effects of cellulase treatment on the properties of Tencel denim fabrics were evaluated by the subjective hand measurements. The results are as follows: As the weight loss increased. fabrics were evaluated as finer, smoother, softer, warmer, more refined (surface properties), more compact and weaker (durability), more flexible, flossier, lighter, softer, thinner (sense of weight), more elastic, and less wrinkly (shape recovery). Fabrics were evaluated to have the dry touch regardless to the rate of weight loss (moisture properties). Overall hand preference of Tencel denim fabrics was in the side of not preferred. Hand of Tencel fabrics seems not to appeal to Korean people. Color preferences were not significantly different among five groups. The correlations between subjective hand and preference showed that fine, smooth, flexible, warm, refined, loose, soft, dry touches were preferred in Tencel denim fabrics.

In the process of turbine modernizations, the investigation of the influences of water passage roughness on radial flow machine performance is crucial and validates the efficiency step up between reduced scale model and prototype. This study presents the specific losses per component of a Francis turbine, which are estimated by CFD simulation. Simulations are performed for different water passage surface roughness heights, which represents the equivalent sand grain roughness height. As a result, the boundary layer logarithmic velocity profile still exists for rough walls, but moves closer to the wall. Consequently, the wall friction depends not only on roughness height but also on its shape and distribution. The specific losses are determined by CFD numerical simulations for each component of the prototype, taking into account its own specific sand grain roughness height. The model efficiency step up between reduced scale model and prototype value is finally computed by the assessment of specific losses on prototype and by evaluating specific losses for a reduced scale model with smooth walls. Furthermore, surveys of rough walls of each component were performed during the geometry recovery on the prototype and comparisons are made with experimental data from the EPFL Laboratory for Hydraulic Machines reduced scale model measurements. This study underlines that if rough walls are considered, the CFD approach estimates well the local friction loss coefficient. It is clear that by considering sand grain roughness heights in CFD simulations, its forms a significant part of the global performance estimation. The availability of the efficiency field measurements provides an unique opportunity to assess the CFD method in view of a systematic approach for turbine modernization step up evaluation. Moreover, this paper states that CFD is a very promising tool for future evaluation of turbine performance transposition from the scale model to the prototype.

An experiment using the $Prim{\ddot{a}}rkreisl{\ddot{a}}ufe$ Versuchsanlage (PKL) was performed for the OECD/NEA PKL-3 Project as a counterpart to a previous test with the large-scale test facility (LSTF) on a cold leg smallbreak loss-of-coolant accident with an accident management (AM) measure in a pressurized water reactor. Concerning the AM measure, the rate of steam generator (SG) secondary-side depressurization was controlled to achieve a primary depressurization rate of 200 K/h as a common test condition; however, the onset timings of the SG depressurization were different from each other. In both tests, rapid recovery started in the core collapsed liquid level after loop seal clearing, which caused whole core quench. Some discrepancies appeared between the LSTF and PKL test results for the core collapsed liquid level, the cladding surface temperature, and the primary pressure. The RELAP5/MOD3.3 code predicted the overall trends of the major thermal-hydraulic responses observed in the LSTF test well, and indicated a remaining problem in the prediction of primary coolant distribution. Results of uncertainty analysis for the LSTF test clarified the influences of the combination of multiple uncertain parameters on peak cladding temperature within the defined uncertain ranges.

Emergency preparedness plan(EPP) is the systematic management of activities that involve a material degree of risk of loss or other damage to the surroundings(people, property and environment), and the boundary of accident recovery plan(ARP). The main purpose of the program is to provide a safety management system to each facility in order to enable to prevent accident and to control accident immediately. The EPP includes not only typical safety-related documentations such as material safety data sheet(MSDS), standard operation procedure(SOP), emergency response plan(ERP). EPP is established basis of the preliminary safety analysis involving risk identification, assessment and prevention plans. The program is also helpful for government or related agencies to control a number of accidents in small-scale companies in the whole country.

Radish (Raphanus sativus L.) has long been recognized as a source of nutrients and phytochemicals. It is well known that the antioxidant properties of radish contributed to its popularity in pharmaceuticals. For this reason, the radish extract aided in the recovery and prevention from diseases. Hence, in this study, the sensory evaluation assessment was conducted following addition of radish oil to almond milk, oat milk, and soy milk (nondairy products) and Kefir, yogurt, and cow milk (dairy products) at different concentrations (containing 0.5% increments from 0% up to 2%). According to the results obtained in this study, all samples containing 0.5% radish oil scored higher on the sensory evaluation scale than the control. It is also very valuable as it is the first study to investigate sensory evaluation assessment by incorporating radish oil into almond milk, oat milk, and soy milk (nondairy products) and kefir, yogurt, and cow milk (dairy products). Furthermore, the results of this study can be used as a foundation for developing future products using radish oil. Additional research on addition of plant-based essential oil to various foods should be conducted.

본 연구는 척수 앞뿔의 세포손상을 준 흰쥐를 대상으로 수영운동과 미노싸이클린의 치료적 중재를 통해 운동기능과 신경계의 회복을 알아보고 운동에 의한 척수손상의 신경학적 회복기전을 밝히는 것의 목적이 있다. 본 연구의 진행은 Sprague-Dawley계 흰쥐 28마리의 허리뼈 1-2번 사이에 6-OHDA로 척수손상을 일으킨 다음 3일 후에 치료를 시작하였다. 수영은 주 5회 15분간 운동을 실시하고 미노싸이클린은 척수손상을 유발한 후 12시간마다 복강내 주입하였다. 척수손상을 유발한 후 치료를 시작하기 전에 운동기능의 평가를 시행하며 2주 동안 4번의 검사가 이루어졌으며, Bcl-2 발현에 관한 측정은 2주간 치료 후 검사하였다. BBB 척도에서 대조군에 비해 실험군에서 7일에 차이가 있었으며, 14일에는 II, III군에 비해 실험군 Ⅳ군에서 증가하였다. Bcl-2의 면역학적 소견에서 실험군 모두 대조군에 비해 척수 앞뿔에서 Bcl-2의 발현이 증가되었으며, 실험군 Ⅳ에서 가장 많은 Bcl-2의 발현이 관찰되었다. 척수손상 후 미노싸이클린과 수영은 행동학적, 면역학적 소견을 긍정적으로 개선시키는 것으로 나타났으며, 수영과 미노싸이클린을 함께 실시한 경우 세포사멸의 감소와 운동기능의 회복에 효과가 있음을 알 수 있었다.
