12주간의 규칙적인 복합운동 프로그램이 비만노인의 신체구성과 간기능에 미치는 영향

The purpose of this study was to investigate the changes of body composition and liver function in obese elderly people after complex exercise programs. These people were classified to two groups, who one group or exercise group(n=13) was participating in an exercise program for 12 weeks, and the other group or non-exercise group(n=13) was not in that program. And the exercise programs were performed by warm up, work-out(involving aerobic exercise and resistance training), and then cool down. The results of all the Studies and inspections are as followed: At first, in the body composition, there were significant differences in body weight, muscle mass, fat mass, percent fat, and body mass index in exercise group. At second, in the liver function, there were no significant differences in both exercise group and control group. But there were a significant differences in T. Bilirubin in control group. In conclusion, the investigation of this paper has shown the results, which involved in positive changes of 12 weeks complex exercise programs on body composition(ex, fat mass) in elderly people who had been to exercise regularly.
Wigner Rotation of a Spin 1/2 Particle near the Event Horizon of a Schwarzschild Black Hole
안도열 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.2I
The effects of Wigner rotation on a particle with spin 1/2 near the event horizon of a Schwarzschild black hole are studied in the Kruskal spacetime. The curvature of spacetime is found to cause a Winger rotation on spin of the particle in the curved spacetime. This implies that, from a quantum information processing point of view, any quantum information encoded in the spin will be dissipated near the black hole. The gravitational field around the black hole, thus, acts like a dissipative quantum channel.
Hawking Effects on the Entanglement near a Schwarzschild Black Hole
안도열 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.2
Hawking radiation effects on an entangled pair near the event horizon of a Schwarzschild black hole are investigated. The Hawking radiation was found to degrade both the quantum coherence of the entangled state and the mutual correlations of the entangled pair. When the black hole evaporated completely, the measure of entanglement vanished, but the classical correlation between the entangled pair still remained.
Effects of Black Hole Evaporation on the Quantum Entangled Sate
안도열 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.4
We investigate the effect of black hole evaporation on the entangled state in which one party of a pair, Alice, falls into the black hole at formation while the other party, Bob, remains outside the black hole. The final state of a black hole is studied by taking into account a general unitary evolution of a black-hole matter state. The mixedness is found to decrease under a general unitary transformation when the initial matter state is in a mixed state and the mean fidelity at the evaporation is smaller than the fidelity of the quantum teleportation by a factor of the inverse square of the number of states of a black hole. The change in the entanglement of the Alice-Bob pair at evaporation is studied by calculating the entanglement fidelity and eigenvalues of the partial transposed block density matrix. The entanglement fidelity is found to be inversely proportional to the square of the Hilbert space dimension N, and the entanglement could survive the evaporation process.
