Making aged exercise by their age is unreasonable because there are differences of personal strength of their body. The three elements which control the aged's, possibility of exercising effectiveness are the level of the physical strength in the present state, potential capacities of physical strength and age. Examined the physical strength of aged, the pliancy of body is considerably marked decline by and large and fast twitch muscle are withered. The reason why aged often do prime exercise like and infant. Aged are not fit for the speedy exercise and they can give full scope to their ability by continuing the long time exercise. The reason why aged should dwindle is mainly the retardation of recovering their fatigue which is related to the decline of oxygen activity. Anaerobic energy supply reduction makes aged be bad far severe physical exercise. Basal metabolic rate of aged rely on physical cellular quantity and people exercising has a high basal metabolic rate because of muscular amount. There were no decline of basal metabolic rate following the age and physical non activiti influences on the atrophy of muscle.

2004년 3월 29일부터 4월 28일까지 본 실험에 참가하기로 동의한 대구광역시 내 모대학에 재학 중 인 20대 초반의 학생 50명을 대상으로 건성과 지성 피부로 나누고 건성과 지성 피부군에 적용한 온천수의 종류에 따라 건성 유산온천군, 지성 유산온천군, 건성 탄산온천군, 지성탄산온천군, 건성 식염온천군, 지성 식염온천군으로 나누어 수분, 유분, pH 실험한 결과 다음과 같은 성적을 얻었다. 1. 유산 온천수가 피부에 미치는 영향을 알아본 결과 피부 상태에 대한 만족도의 경우, 건성 피부군(p<0.05)과 지성피부군(p<0.01) 모두 유산 온천수를 적용하기 전에 비해 적용 후에 만족도가 상승하였다. 수분 함량, 유분 함량, pH의 경우 건성 피부군에서는 통계적인 차이는 없었지만 약간씩 증가하였던 반면, 지성피부군에서는 수분 함량은 통계적인 차이는 없지만 약간 감소하였고, 유분은 증가하였으며, pH는 감소하였다. 2. 탄산 온천수가 피부에 미치는 영향을 알아본 결과 피부 상태에 대한 만족도의 경우, 건성피부군에서 만족도가 상승하였지만 통계적인 차이가 없었던 반면 지성피부군에서는 만족도가 상승하였다(p<0.01). 수분함량, 유분함량, pH의 경우 건성피부군에서는 통계적인 차이는 없지만 약간씩 증가하였으며, 지성피부군에서는 수분함량이나 pH는 통계적인 차이는 없지만 약간 증가한 반면 유분함량의 경우는 많은 양이 감소하였다(p<0.01). 3. 식염 온천수가 피부에 미치는 영향을 알아본 결과 피부 상태에 대한 만족도의 경우, 건성 피부군이나(p<0.05), 지성 피부군(p<0.05) 모두에서 만족도가 상승하였다. 수분 함량, 유분 함량, pH를 보면 건성 피부군에서는 통계적으로 유의한 차이가 날 정도로 수분함량(p<0.05)과 유분함량(p<0.05)이 증가하였다. 반면 pH는 약간 감소하였지만 통계적인 차이는 없었다. 지성 피부군의 경우는 수분 함량, 유분 함량 모두 약간 증가하였지만 유의한 차이는 없었고, pH는 오히려 약간 감소하였지만 역시 통계적인 차이는 없었다. 이상의 결과를 볼 때 온천수는 종류에 관계없이 피부 만족도를 증가시킬 수 있으며, 특히 탄산 온천수의 경우는 지성 피부군의 유분 감소에 더 효과적임을 알 수 있고, 식염 온천수는 지성 피부군에 비해 건성 피부군의 수분 함량과 유분 함량을 증가시키는데 더 효과적인 반면 유산 온천수는 피부에 많은 영향을 주지 못하였음을 알 수 있다.

박래준,손호희,조정선,오현주,이현희,이문환,김성길,Park, Rae-Joon,Son, Ho-Hee,Cho, Jeung-Sun,Oh, Hyen-Ju,Lee, Hyeon-Hee,Lee, Moon-Hwan,Kim, Seong-Gil 대한물리치료학회 2011 대한물리치료학회지 Vol.23 No.2

Purpose: The purpose of this study was to determine the correlations, if any, between SPPB (Short physical performance battery), FRT (Functional reach test), and TUG (Timed up and go test) in hospitalized frail people. Methods: Seventy frail elderly patients (male/female: 16/54) participated in this study. All subjects could walk with or without an assisting device and they had no mental problems. Subjects were scored on physical functioning using the SPPB, FRT, and TUG. The data were analyzed using Pearson Correlation Coefficients. Results: There was a statistically significant difference between (a) SPPB and (b) FRT (p<0.01) and TUG (p<0.01). SPPB and FRT scores showed a positive correlation (r = 0.38) and SPPB and TUG scores showed a negative correlation (r = -0.56). Conclusion: SPPB, FRT, TUG scores are correlated with each other. From these results, we conclude that the SPPB is a useful method for predicting walking, balance, and physical function in frail elderly people.

경두개 직류 전류 자극이 시지각 과제의 수행 능력에 미치는 영향

As a non-invasive technique for brain stimulation, transcranial direct current stimulation (tDCS) modulates the brain activity. Recent studies reported that tDCS enhances motor learning and working memory. Therefore, this study examined the effect of tDCS on the primary motor cortex of the non-dominant hemisphere in motor performance. Twenty-two healthy subjects were enrolled in this study. They were divided randomly into two groups, such as the experimental group or sham-controlled group. In the experimental group, tDCS (1 ㎃, 20 mins) was applied to the primary motor cortex and sham-control group was applied for 30seconds only. In addition, a serial reaction time task was carried out before and after tDCS in both groups. There was enhanced motor performance in both groups due to the repetitive motor execution. However, the experimental group showed larger changes in their reaction time. Overall, tDCS of the primary motor cortex is effective in stimulating the motor performance in healthy subjects. The results suggest that tDCS may enhance the beneficial effects of neurorehabilitative treatments in stroke patients. 경두개 직류 전류 자극법은 영구적 이식이나 침습적인 방법이 아닌 비침습적으로 뇌를 자극하는 방법으로써 뇌의 활성화를 조절하여 학습능률 향상을 도모하는 뇌기능 치료법이다. 경두개 직류 전류 자극법이 뇌기능장애환자나 신경계 손상환자의 뇌기능 활성화에 대한 치료적 프로토콜로 제안되는 이유는 시지각과제에 대한 운동학습과 작동 기억 향상에 있으나 아직 시지각과제의 운동수행력 향상을 뒷받침하는 논문은 많지 않다. 그러므로, 본 연구는 비우성 뇌반구의 일차운동영역에 경두개 직류 전류로 자극을 가하여 시지각과제의 운동 수행력에 미치는 영향을 정량적으로 알아보기 위하여 수행되었다. 22명의 정상 성인을 대상으로 무작위로 실험군과 허위-대조군으로 나누었으며, 실험군에서는 비우세 뇌반구의 일차운동영역에 경두개 직류 전류 자극을 1㎃으로 20분 동안 적용하였고, 허위-대조군은 같은 부위에 30초동안 자극하고 대상자들이 모르도록 장치의 전원을 끈 상태로 유지하였다. 연속반응시간과제는 자극 전과 후에 두 그룹 모두에게 반응 시간의 변화를 확인하기 위해 적용되었다. 본 연구의 결과, 자극 전·후 반응시간에는 통계적으로 유의한 차이가 있었으나(p< .05), 집단간과 상호작용에는 통계적으로 유의하지 않았다(p> .05). 반복적인 운동 수행 효과로 인해 두 집단 모두에서 수행력이 향상되었으나, 경두개 직류 전류 자극을 적용한 실험군에서 좀 더 많은 반응시간의 변화가 보였다. 그러므로, 경두개 직류 전류 자극을 적용한 집단이 허위-대조군보다 반응시간에서 좀 더 많은 변화가 있었음을 알 수 있었다. 앞으로의 연구에서 적절한 과제를 통해 효과성이 검증이 된다면 뇌졸중을 가진 환자의 뇌 활성화를 조절하는 신경재활치료에 중재법으로 유용할 것이라 생각된다.

Far infrared를 이용한 생체정보 인터페이싱에 대한 연구

박래준,김재윤,Park, Rae Joon,Kim, Jae-Yoon 대한물리치료학회 2001 대한물리치료학회지 Vol.13 No.3

The Sun's ray is composed of Infrared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(Far infrared; 60%), IR(Infrared; 20%), and UV(Ultra Violet; 20%). Human beings has utilized FIR already from time immemorial. Hershel found out Infrared for the first time. in the Industrial Revolution the Infrared and FIR had been begun to use making products. In these days, with contemporary science FIR would be begun to clear up the implication in the human body and organic compound. IR classified by wavelength three parts NlR, MIR, FIR. There is FIR which is radiated from healthy human body the wave length is 8-l4m. The human body is composed of proteins which get easily changed by a thermal factor (about 42 $^{\circ}$C over). FIR with low temperature can deeply penetrate on the human body composed things without troublesomes, since FIR has effectively operated on the human body at low temperature (35-40 $^{\circ}$C). When FlR penetrated on the human body. it would inhibit the abnormal genes and cells expression, and then information of DNA and RNA would be reexpressed for arranging DNA and RNA abnormal state. As FlR's receptors in the body, it could be presumed that N-glycosyl linkage of purine and deoxyribose, RNA splicing process, and Heat shock protein. To take the FIR which was a optimized wavewlength and strength, at first, we induced the characteristic algorithm and the computerized programing. Then we formed that the formular of optimized FIR with physical, mathematical logic and theory. especially, Plank, Kirchhoff, Wien, Stefan-Boltzmann's logic and law. In the long run, the formular was induced with integration mathematical, since we had to know the molecular wavelength. Based on the induced formular as above, we programmed the optimized FlR radiating computerized program. In this research, we designed the eletronic circuit f3r interfacing with human body to diagnosis and treatment with FIR sensor which radiated FIR wavelength optimized.

CORIUM BEHAVIOR IN THE LOWER PLENUM OF THE REACTOR VESSEL UNDER IVR-ERVC CONDITION: TECHNICAL ISSUES

박래준,강경호,홍성완,김상백,송진호 한국원자력학회 2012 Nuclear Engineering and Technology Vol.44 No.3

Corium behavior in the lower plenum of the reactor vessel during a severe accident is very important, as this affects a failure mechanism of the lower head vessel and a thermal load to the outer reactor vessel under the IVR-ERVC (In-Vessel corium Retention through External Reactor Vessel Cooling) condition. This paper discusses the state of the art and technical issues on corium behavior in the lower plenum, such as initial corium pool formation characteristics and its transient behavior,natural convection heat transfer in various geometries, natural convection heat transfer with a phase change of melting and solidification, and corium interaction with a lower head vessel including penetrations of the ICI (In-Core Instrumentation)nozzle are discussed. It is recommended that more detailed analysis and experiments are necessary to solve the uncertainties of corium behavior in the lower plenum of the reactor vessel.
