수용성 Vitamin이 운동에 미치는 영향

채광호 혜전대학 2000 論文集 Vol.18 No.-

The purposes of this study were to investigate the relation between the function of the water soluble vitamin and the sport. The required quantity for the water soluble vitamin like vitamin B₁ and vitamin C was increased by the sport, and 손 increase of the required quantity for the vitamin like vitamin B₂, niacin, pantothenic acid, and biotin is estimated through the rise of the energy replacement, but now the relation between the function of some water soluble vitamin and the sport is not clear. Vitamin B_(6) and hydrochronic acid have a deep relation with the replacement of amino acid, and the increase of the required quantity for those vitamin and the protein intake is estimated. But more systematic study on the relation between the required quantity for the vitamin and the sport will be necessary. The vitamin deficiency will decrease the sportsmen's condition and their atheletic ability, and the sportsmen must take enough vitamin at each meal not to be deficient in vitamin. Not to be deficient in vitamin it is very important for the sportsmen to have a balanced diet at each meal. Too much vitamin intake will elevate the sportsmen's performance, but it can cause another vitamin deficiency. Because the evil influence of too much vitamin intake is not studied, the sportsmen who take vitamin drug habitually will have to consider their daily vitamin intake closely.

We report a 70 year-old man with Binswanger's disease associated with mood symptoms. He was apparently well until 15 years ago when the treatment-resistant atypical mood symptoms had been appeared. He showed a fluctuating course in mental disturbance, such as irritable and labile affect, emotional incontinence, and irritable behavior. Two years ago, he was diagnose as hypertension, renal failure, and heart failure. He was admitted to psychiatric ward due to irritable mood, dysarthria, lack of bladder control, gait disturbance, and impulsive behaviors, which had been aggravated during the last 2 months. In physical examination, he had hypertension and both pretibial pitting edema was revealed, and also in neurological examination, exaggeration of deep tendon reflexes and weakness of extremities were found. On mental status examination, he showed irritable and labile mood with mild cognitive disturbances. Brain MRI demonstrated multifocal high signal intensity in periventricular white matter, both basal ganglia, and thalami on the T2 imaging. These findings were compatible with Binswanger's disease with mood symptoms.

THIAMIN의 대사적 기능에 관한 고찰

채광호 혜전대학 2001 論文集 Vol.19 No.-

The effects of thiamin intake have not been clearly investigated, however, RDA has reported that, for most of healthy men and women, as much as one or twice amount of thiamin intake would be proper for aerobic exercises. Although other researches also reported that continuation of streneous physical activities lead a significant increase of thiamin intake, .we still wait more experimental result for that problem. Physical exertion needs an increase of thiamin intake when carbohydrates are the major source of energy expenditure and there is an additional demand for TDP-dependent catabolism of BCCA. An experiement with human sample is needed within the limitation of standarized thiamin intake and intake of vitamin-free high-carbohydrate three to four hours before particular physical activity. This double blind control experiment should be designed to deter mine most desirable amount of thiamin intake to minimize fatigue which will cause by continued vigorous physical activities. The use of sensitive measurements of ETKA and /or HPLC-determined TDP in erythrocytes provides and opportunity to demonstrate thiamin demands during the peak of streneous physical activity. More experiments are needed to find how the right amount of protein intake would affect the need of thiamin intake during physical exertion.

The purposes of this study were to investigate the factors of the physical strength between right handers and left handers, to help find the excellent players and train them early according to the difference of the physical strength in connection with the handedness, and to help their body develop symmetrically by minimizing the partiality for the handedness when we train the students. To accomplish these purposes, I questionaired some male highschool students in H-kun, Chungnam province, and found their handedness. I selected 70 right handers and 55 left handers as an object of this study, and investigated physical strength factors in connection with the handedness. The results were as follows : 1. In the test of standing on one foot with their eyes opened to the effective side of right handers and left handers, the left foot of left handers was superior to the right foot of right handers, and in the physical strength of the ineffective side the left handers were superior to the right handers. In the test of standing on one foot with their eyes closed, the ineffective side of right handers was superior to that of left handers. 2. In the difference of physical strength factors in connection with the handedness between right side and left side, the difference between right side and left side of right handers was more than that of left handers except in stepping.

마아케팅 計劃에 있어서의 適應的 意思決定에 關한 硏究

崔光龍 충남대학교 경영대학원 1974 經營學論文集 Vol.1 No.-

One of the great problems which modern business is how to adapt itself to environments which are changing movingly and how to continue to exist for a long time. When business becomes worse in the pathological process, repeats is vicious circle, and its destructive state occurs, there is no mechanism to return business automatic ally to a balanced state in theory of economics and management which, up to now, have partically been developed. W. Alderson sets a definite form on the relationship between the business and the external environments, and H.A.Simon laid emphasis on the projective mechanism in the inner business. As we can unify theory of both, we can develop the theoretical system in the strategical marketing, which has been disregarded unstil now. Therefore, the important task of this report, to begin with in order to analize systematically the basic characteristics and the strategical marketing planning, is to prove whether this is effective as an important framework. In this meaning, I would like to put emphasis on the following points and tried to develop my report. 1. Manesting strategical side in marketing planning. 2. Regulating obviousely the concept of strategical decision making use of the theory of adaptive decision marking. 3. Applicating the adaptive decision, mainly developed in the fields of psychology and systematic organization for marketing planning. 4. Application the theory of systematic method for the framing of complicated marketing planning model. 5. Establishing basic frame for designing a certain total system through the subsystem in marketing planning. In order that business, in the task of market planning, which is changing movingly, may positively adapt itself to environments, top manegement has to develop mechanism of decision marking, aimed at a high target, and I think decision in marketing planning is improvable and methodological science, which has not fot fully been developed. So I am going to try to prove the adaptive decision, developed by the people of Carnegie, with Simon as its central figure, whether I can solve it systematically, Adapting strategical marketing planning. But till now the point of importance in decision markingin marketing has been laid on the physical and direction alone. But in order to strengthen the environments in business, we must have a theory, aimed at human being. Adjusting a scientific method called Computer Simulation, we are able to solve the complicated marketing problems.

Radiostrontium passes the placental barrier in pregnant rodents very well. Chitosan, a natural nontoxic chelator, was reported to reduce whole body retention of radiostrontium in mice. The aim of the present study was to evaluate water soluble chitosan as a blocking agent of transplacental transfer of radiostrontium in pregnant mice. Twenty pregnant mice wre divided into four groups : control and three groups of chitosan treatment(groups 1 to 3). Sr-85(15KBq in 0.2ml saline) was subcutaneously injected into pregnant mice at the 17th day of pregnancy. In control mice, 0.2ml saline was given 5 hours after the injection of Sr-85. In group 1.1% water soluble chitosan was given subcutanously for two days, twice daily after the injection of Sr-85. In group 2, 10% water soluble chitosan was given orally for 15 days before conception. In group 3, 0.3% water soluble chitosan was injected intravenously for 15 days, once daily before conception. Gamma counting of newborns were done at days 0, 2 and 7 after their births. Whole body retention of Sr-85 in newborns of control mice at days 0, 2, 7 were 3.1 ±0.3%, 2.9 ±0.3%, 2.8 ±0.3% respectively. In experimental groups, whole body retention of Sr-85 was significantly lower thanthat of control(p<0.01) and no statistical difference was noted between them. In group 1, the values were 2.1 ±0.3%, 1.4 ±0.1%, 1.4 ±0.1%, respectively. In group 3, they were 2.1 ± 0.2%, 1.7 ± 0.2%, 1.6 ± 0.2%, respectively. In conclusion, the water soluble chitosan reduced transplacental contamination of radiostrontium in pregnant mice.

Conventional UPS(Uninterruptible Power Supply) systems offer load voltage continuity and are standing by power outage when the utility power is maintained normal. It has a low efficiency because it operate at power failure. Harmonic currents induced by switching supplies badly distort the output waveform of power sources. Utility power quality has become an important issue recently. So various APF(Active Power Filter) has been proposed to suppress harmonics caused by nonlinear load. This paper presents a new concept of UPS system that provides the combined functions of APF. An off-line UPS similar to voltage type APF that proposed in this paper. The operation of the new off-line UPS system used not only eliminate the harmful harmonics caused by nonlinear load but also offer load voltage continuity. A half-bridge inverter is utilzed to deliver clean power to the loads during power outage or to suppress the harmonics from the line current in normal. It is efficient and economical because the one inverter use for combined function. We use 8051 single chip microprocessor for software synchronization, generation of reference voltage waveform and SSR(Solid State Relay)control. Its transient performance is good at the moment of the change of operation mode.
