스포츠 과학 분야에서는 운동 선수들의 경기력 향상과 운동 피로의 신속한 회복을 도모하기 위하여 한약을 복용하고 그 효과와 유의성에 대하여 연구가 활발히 이루어지고 있다. 격심한 운동을 수행할 때 나타나는 Glucose 등 에너지원의 고갈, Lactate 등 대사 산물의 축적, 전해질의 불균형 등의 여러 제반 증상이 氣虛로 인하여 나타나는 전신의 증후와 유사하다고 생각하여 補中益氣湯을 투여한 후 인체의 대사 변화를 관찰함으로서 운동수행능력에 미치는 영향과 유의성을 평가하고자 하였다. 본 연구는 장거리 달리기 선수를 대상으로 2주간의 補中益氣湯의 투여가 에너지 대사 및 전해질대사에 미치는 영향을 규명하기 위하여 최대심박수의 70% 강도의 운동을 실시한 후 운동전 안정시, 운동 직후, 휴식 후 10분, 휴식 후 30분, 휴식 후 1시간으로 나누어 혈액검사를 하였을 때 나타나는 각종 변인의 반응 양상을 비교 분석하여 유의한 결과를 얻었다. 혈중 에너지 대사에서는 free fatty acid와 Lactate 반응에서 유의성 있는 차이가 나타났고, 전해질대사에서도 Na^(+), Cl-와 K^(+) 반응에서 모누 유의성 있는 차이를 나타냈다. 그러므로 補中益氣湯은 에너지 및 전해질 대사에서 유의성있는 변화를 나타내었으며 운동수행능력의 향상에 유효하였다. Objective This experimental study was designed to investigate effects of Bo-joong-ik-gi-tang administration among long distance runners on changes of the energy and electrolyte metabolism. Materials and Methods All subjects were divided randomly with two groups, Bo-joong-ik-gi-tang Group (N=4) and control group (N=4) and performed to run the 400m track with 70% of HR max about 1 hour. The blood samples were collected from antecubital vein by 5㎖ syringes at before exercise, immediateIy after exercise, recovering- 10 min, recovering-30 min, recovering-1 hour. These sampie were used to analyze for the factors of the changes on metabolic responses. Firest, the primary factors on the changes of the energy metabolism were checked ; Glucose, Free fatty acid, Lactate, LDH. Second, the primary factors on the changes of the electroIyte metabolisrn were checked ; Na^(+), Cl^(-), K^(+). Results 1. The change of the energy metabolism 1) Glucose response was not shown significant difference between two groups. 2) Free fatty acid response in Bo-joong-ik-gi-tang group was significantly increased at recover-10 min. 3) Lactate response in Bo-joong-ik-gi-tang group was significantly decreased at immediately after exercise, recover-10 min, recover-30 min. 4) LDH response was not shown significant difference between two groups. 2. The change of the electrolyte metabolism 1) Na^(+) response in Bo-joong-ik-gi-tang group was shown significant difference between two groups at before exercise. 2) C^(-) response in Bo-joong-ik-gi-tang group was significantly increased at before exercise, immediately after exercise. 3) K^(+) response in Bo-joong-ik-gi-tang group was significantly increased at recover-10 min. Conclusion According to the above results, it was shown that Bo-joong-ik-gi-tang had the positive effects on changes of the energy and electrolyte metabolism for the long distance runners.

Purpose : Intraoperative suprachoroidal hemorrhage is one of the most serious complications. We report a case of suprachoroidal hemorrhage during phacoemulsification surgery, was managed properly. Methods : Suprachoroidal hemorrhage occurred during phacoemulsificaiton in other hospital. The patient was referred to our department immediately after closing the surgical wound. On initial examination, iris and vitreous were prolapsed through surgical wound. Ciliary body was closely place to anterior chamber, and retina was not visible. Results : Prolapased ocular tissue were reduced by emergency operation. We controlled the patient’s intraocular pressure and inflammation. Ultrasonography was repeatedly performed to check the degree of liquefaction of suprachoroidal hemorrhage. After 9 days of suprachoroidal hemorrhage onset, vitrectomy and drainage through sclera was performed. Postoperative state was stable with successful removal of suprachoroidal hemorrhage. After 2 weeks of secondary operation, retinal detachment has occurred on nasal retinal area, so we performed scleral buckling and endolaser photocoagulation. After 6 months, retina was attached well and intraocular pressure was in normal range. Conclusion : In suprachoroidal hemorrhage, drainage of suprachoroidal hemorrhage after liquefaction of thrombi is effective. After successful drainage, postoperative complications may accompany such as retinal detachment or elevation of intraocular pressure. 목적 : 술중 발생하는 맥락막상 출혈은 매우 심각한 합병증이다. 저자는 수정체 유화술 중에 발생한 맥락막상 출혈을 적절히 대처한 증례를 보고하는 바이다. 대상과 방법 : 수정체 유화술 중 발생한 맥락막상강 출혈환자가 수술창을 봉합 후 즉시 본원으로 전원되었다. 초진시 홍채와 유리체가 수술창을 통해 탈출되어 있었으며, 전방을 통해 모양체가 확인되었으나, 망막은 보이지 않았다. 탈출된 안구내 조직을 응급수술을 통해 복원 후 환자의 안압과 염증을 조절하였다. 초음파를 반복적으로 실시하여 맥락막상 출혈의 액화 정도를 확인하였으며, 출혈 9일 후 유리체 절제술과 공막을 통한 배액술을 시행하였다. 결과 : 맥락막상 출혈이 성공적으로 제거되었으며 술 후 상태는 안정적이었다. 수술 2주 후 비측 망막 박리가 발생하여 공막돌륭술과 안구내 삽관 레이저술을 시행하였다. 6개월 후 망막은 잘 붙어있었으며, 안압은 정상 범위를 유지하였다. 결론 : 맥락막상 출혈의 경우 출혈의 배액 시기를 결정하는 것이 어렵지만, 규칙적인 초음파를 통해 배액술의 시기를 결정할 수 있다. 또한 맥락막상강 출혈의 성공적인 배액 이후에도 망막박리 및 안압상승과 같은 합병증의 동반에 대해 유념해야한다.

A TDC(Time Delay Control) theory is applied to the the position control problems of flexible robot manipulators subjected to unknown dynamics and distrurbances. One link flexible manipulator system with tip mass is represented as a simple spring-mass-damper syseem and AC servo motor is used as the actuator. Based on the system model, the TDC is designed, and the PI-controller is also designed for comparison. The control performance of TDC is evaluated through a series of simulations and experiments. The simulational and wxperimental results show that the TDC is much robust than the PI-controller to the unknown dynamics and disturbances.

The experimental tie line data were correlated with NRTL model, and the parameters in NRTL model and the calculated values of tie lines were predicted. The plait point were calculated by NRTL model for the ternary systems of pyridine-water with monochlorobenzene, o-xylene and aniline as solvents at 25℃. The selectivity curves in the equilibrium of ternary systems compared with experimental data and values calculated using NRTL model.

The military alliance between the Republic of Korea and the United States of America, which has lasted for over 50 years, is under severe challenge. Demands for changes to the alliance are likely to only strengthen in the future. A self-reliant national defense is a popular idea with both the Korean public and government. Indeed, the joint statement at the recent Sept. 17th six party talks is a manifestation of this sentiment and has created new momentum for a different type of alliance. This article argues that a new framework for the alliance will be essential in establishing an effective defense going forward. The Korean government is attempting to achieve peaceful co-existence on the Peninsula as an alternative to the current armistice regime, that North Korea and other members of six party talks support. This new 'peace regime' will undoubtedly demand changes to the ROK -US Combined Forces Command, Armistice Committee, wartime operational command Authority, etc. The time has come for a fundamental review of and a drastic revision to the current alliance between the ROK and USA. This article addresses the qualitative differences in the ROK-USA alliance during and after the Cold War. After reviewing the qualitative changes in the alliance, it subsequently identifies key concerns and makes suggestions on how best to strengthen and consolidate the alliance, preparing for an era of peaceful rapprochement on the Korean peninsula.

DC-DC buck converters with closed-loop pulse width modulation(PWM) are strongly nonlinear systems which are potentially chaotic. We investigated experimentally a modified buck converter using low pass filter(LPF) or error amplifier or pulse filtering circuit for conduction noise problems occurring in the output voltage. The proposed circuit is simple and improve efficiency and stability above 50% of duty ratio. In this paper, they reveal high efficiency and smaller ripple voltage for wide industrial application.
