I'o laecome a good dancer, she (he) must have a talent or capacity in aesthetic and physiological fields of dance, In this paper, I refer mainly to the importance of the movement and human laody. I classified the movement as "movement in calm" and "mavement in action" "movement in calm" means a series of movement which are moved used by the upper part of the body. The center of this movement is the trunk. The trunk is that part of the body which includes both the pelvis and the shoulder girdle and it is moved from the hip joints. Its actions are defined by the movement of the spine which show great versatility. This movement includes the chest "looking" The chest "looking means that as if in the movement of the head which frequently result from directing our face towards something at which we wish to look. In this way we can imagine the chest can do the function of" looking "movement in action" means a transport of body from one place to another place used by feet. We can develope the creative power in dance through the trainning which includes various usage of this movemeut "movement in calm" and "movemeut in action" both have an important role in dance. To become more advanced dancer, everydancer must know how to use the movement in reality and understand the structure of human body. This paper was written to satisfy such needs to become a good dancer.

具本淑,崔德瓊 고려대학교 의과대학 1972 고려대 의대 잡지 Vol.9 No.2

Oxygen consumption, pulmonary ventilation and heart rate were measured on 14 college girls(average age: 18.5 years) walking on a treadmill carrying a load of 7.8㎏ either on hand, back, or head. The speed of walking was 4, 5, and 5.5㎞/hr with zero grade. Comparisons were made between free walking without load and walking with various types of loads carrying. The following results were obtained. 1. Oxygen consumption in resting state was 174±89㎖/min, 3.59±0.99㎖/㎏/min, or 4.73±1.20㎖/㎏ LBM/min. 2. Oxygen consumption in free walking without load was the smallest as compared to the walking with various types of loads carrying. Oxygen consumption in free walking at the speed of 4,5 and 5.5㎞/hr was 525±181, 633±145, and 706±166㎖/min, respectively. On the body weight basis it was 10.85±3.71, 13.08±2.97 and 14.66±3.33㎖/㎏, respectively. 3. Oxygen consumption in hand load was the greatest as compared to the walking with the other type of load. Namely, oxygen consumption at the speed of 4.5 and 5.5㎞/hr was 673±149, 768±167 and 843±108㎖/min, respectively. On the body weight basis the values were 13.94±3.12, 16.17±3.57 and 17.39±2.06㎖/㎏, respectively. 4. Oxygen consumption in walking with a load on back was the smallest as compared to the walking with the other type of load. Oxygen consumption in walking with a load on back at the speed of 4, 5, and 5.5㎞/hr was 12.08±4.11, 14.73±3.16, and 15.19±2.83㎖/㎏, respectively. 5.. Oxygen consumption in walking with a load on head at the speed of 4, 5 and 5.5㎞/hr was 13.18±3.21, 13.60±2.48 and 13.43±2.31㎖/㎏, respectively. The oxygen consumption in the order of magnitude was hand load, head load, and back load walking. 6. Oxygen consumption increased as the speed of treadmill increased in free walking without a load, walking with a load on hand, and on back. On head load walking, however, this trend was not manifest. 7. The changes in pulmonary ventilation and heart rate followed the same pattern as the oxygen consumption when speed of walking and types of loads changed. Pulmonary ventilation ranged between 17.52 and 26.85ℓ/min and heart rate ranged between 102 and 124beats/min. 8. Number of strides per minute ranged between 116 and 130strides/min. It was greatest in hand load walking and smallest in back load walking and the value of head load walking was in the middle.

Gonadotropins, Prostaglandin $F_{2{\alpha}}$ 및 Ouabain이 황체막의 $Ca^{++}-ATPase$ 활성도에 미치는 영향

구본숙,김인교,Koo, Bon-Sook,Kim, In-Kyo 대한생리학회 1987 대한생리학회지 Vol.21 No.1

It has been reported that the luteal function may be regulated by the intracellular $Ca^{++}$ level which may be adjusted partially by the high affinity $Ca^{++}-ATPase$ in luteal cell membranes. Then, one may expect that luteotropic and/or luteolytic agents, such as gonadotropins, prostaglandin $F_{2{\alpha}}\;(PGF_{2{\alpha}})$ and ouabain, affect the intracellular $Ca^{++}$ level. In this present study, therefore, we examined the effects of luteinizing hormone (LH, or human chorionic gonadotropin, hCG), $PGF_{2{\alpha}}$ and ouabain on the kinetic properties of the high affinity $Ca^{++}-ATPase$ in light membrane, heavy membrane, and microsomal fractions from the highly luteinized ovary. LH (or hCG) increased the affinity and the Vmax for $Ca^{++}$ both in light membrane and heavy membrane. $PGF_{2{\alpha}}$ increased the Vmax in light membrane and decreased the Km in heavy membrane for $Ca^{++}$ at low concentration $(5\;{\mu}g/ml)$. At higher concentration, however, $PGF_{2{\alpha}}$ oppositly affected on kinetic properties, that shown at low concentration. Ouabain, a potent inhibitor of $Na^+-K^+-ATPase$, increased the Km at high concentration $(10^{-4}\;M)$, however, decreased the Vmax for $Ca^{++}$ in light membrane at low concentration $(10^{-6}\;M)$. Also, ouabain increased the Km for $Ca^{++}$ in heavy membrane without changes in the Vmax at both concentrations. It seems that LH and low dose of $PGF_{2{\alpha}}$ increase the intracellular $Ca^{++}$ level and cause in activation of $Ca^{++}-ATPase$, however, higher dose of $PGF_{2{\alpha}}$ and ouabain inhibit directly $Ca^{++}-ATPase$ activity and result in increase in intracellular $Ca^{++}$ level. According to the above results, we suggest that luteotropic and/or luteolytic agents regulate the luteal progesterone $(P_4)$ production through two different pathways; one is cyclic adenosine monophosphate (cAMP)-dependent and another is $Ca^{++}-dependent$. Intracellula. $Ca^{++}$ level regulated by the high affinity $Ca^{++}-ATPase$ may affect both pathways in a time-dependent fashion. LH (or hCG) acts on the luteal $P_4$ production via both pathways. The initial step is $Ca^{++}$ dependent, and the late step is cAMP dependent. $PGF_{2{\alpha}}$ and ouabain increase the intracellular $Ca^{++}$ concentration so that basal luteal $P_4$ production is increased and LH-stimulated $P_4$ production is inhibited by the inhibiting LH-dependent adenylate cyclase activity.

Gonadotropins, Prostaglandin F_2α 및 Ouabain이 황체막의 Ca⁺⁺}-ATPase 활성도에 미치는 영향

구본숙(Koo, Bon-Sook),김인교(Kim, In-Kyo) 대한생리학회 1987 대한생리학회지 Vol.21 No.1

It has been reported that the luteal function may be regulated by the intracellular Ca⁺⁺ level which may be adjusted partially by the high affinity Ca⁺⁺-ATPase in luteal cell membranes. Then, one may expect that luteotropic and/or luteolytic agents, such as gonadotropins, prostaglandin F_2α (PGF_2α) and ouabain, affect the intracellular Ca⁺⁺ level. In this present study, therefore, we examined the effects of luteinizing hormone (LH, or human chorionic gonadotropin, hCG), PGF^2α and ouabain on the kinetic properties of the high affinity Ca⁺⁺-ATPase in light membrane, heavy membrane, and microsomal fractions from the highly luteinized ovary. LH (or hCG) increased the affinity and the Vmax for Ca⁺⁺ both in light membrane and heavy membrane. PGF^2α increased the Vmax in light membrane and decreased the Km in heavy membrane for Ca⁺⁺ at low concentration (5 μg/ml). At higher concentration, however, PGF^2α oppositly affected on kinetic properties, that shown at low concentration. Ouabain, a potent inhibitor of Na⁺-K⁺-ATPase, increased the Km at high concentration (10^-4 M), however, decreased the Vmax for Ca⁺⁺ in light membrane at low concentration (10^-6 M). Also, ouabain increased the Km for Ca⁺⁺ in heavy membrane without changes in the Vmax at both concentrations. It seems that LH and low dose of PGF^2α increase the intracellular Ca⁺⁺ level and cause in activation of Ca⁺⁺-ATPase, however, higher dose of PGF^2α and ouabain inhibit directly Ca⁺⁺-ATPase activity and result in increase in intracellular Ca⁺⁺ level. According to the above results, we suggest that luteotropic and/or luteolytic agents regulate the luteal progesterone (P₄) production through two different pathways; one is cyclic adenosine monophosphate (cAMP)-dependent and another is Ca⁺⁺-dependent. Intracellula. Ca⁺⁺ level regulated by the high affinity Ca⁺⁺-ATPase may affect both pathways in a time-dependent fashion. LH (or hCG) acts on the luteal P₄ production via both pathways. The initial step is Ca⁺⁺ dependent, and the late step is cAMP dependent. PGF^2α and ouabain increase the intracellular Ca⁺⁺ concentration so that basal luteal P₄ production is increased and LH-stimulated P₄ production is inhibited by the inhibiting LH-dependent adenylate cyclase activity.

황체막에서의 $Ca^{++}-ATPase$의 특성

최규복,구본숙,김인교,Choi, Gyu-Bog,Koo, Bon-Sook,Kim, In-Kyo 대한생리학회 1986 대한생리학회지 Vol.20 No.2

It has been reported that the luteal function may be regulated by the intracellular calcium in luteal cells (Higuchi et al, 1976; Dorflinger et at, 1984; Gore and Behrman, 1984) which is adjusted partially by $Ca^{++}-ATPase$ activities in luteal cell membranes (Verma and Pennistion, 1981). However, the physicochemical and kinetic properties of $Ca^{++}-ATPase$ in luteal membranes were not fully characterized. This study was, therefore, undertaken to partially characterize the physicochemical and kinetic properties of $Ca^{++}-ATPase$ system in luteal membranes and microsomal fractions, known as an one of the major $Ca^{++}$ storge sites (Moore and Pastan, 1978), from the highly luteinized ovary Highly luteinized ovaries were obtained from PMSG-hCG injected immautre female rats. Light membrane and heavy membrane fractions and microsomal fractions were prepared by the differential and discontinuous sucrose density gradient centrifugation method desribed by Bramley and Ryan (1980). Light membrane and heavy membrane fractions and microsomal fractions from highly luteinized ovaries are composed of the two different kinds of $Ca^{++}-ATPase$ system. One is the high affinity $Ca^{++}-ATPase$ which is activated in low $Ca^{++}$ concentration (Km, 10-30 nM), the other is low affinity $Ca^{++}-ATPase$ activated in higher $Ca^{++}$ concentration $(K_{1/2},\;40\;{\mu}M)$. At certain $Ca^{++}$ concentrations, activities of high and low affinity $Ca^{++}-ATPase$ are the highest in light membrane fractions and are the lowest in microsomal fractions. It appeares that high affinity $Ca^{++}-ATPase$ system have 2 binding sites for ATP (Hill's coefficient; around 2 in all membrane fractions measured) and the positive cooperativity of ATP bindings obviously existed in each membrane fractions. The optimum pH for high affinity $Ca^{++}-ATPase$ activation is around S in all membrane fractions measured. The lipid phase transition temperature measured by Arrhenius plots of high affinity $Ca^{++}-ATPase$ activity is around $25^{\circ}C$. The activation energies of high affinity $Ca^{++}-ATPase$ below the transition temperature are similar in each membrane fractions, but at the above transition temperature, it is the hightest in heavy membrane fractions and the lowest in microsomal fractions. According to the above results, it is suggested that intracellular $Ca^{++}$ level, which may regulate the luteal function, may be adjusted primarily by the high affinity $Ca^{++}-ATPase$ system activated in intracellular $Ca^{++}$ concentration range $(below\;0.1\;{\mu}M)$.
