  • Subject : The application of eight extra Meridians theory to birth physiology of Korean Medicine. Objective : This study suggests physiological theories in child birth in Korean Medicine. Method : First, the application of eight extra Meridians and extraordinary organs theories to physiology, pathology, pregnancy, postnatal period of women were examined based on major publications and theories of some historical characters. This work provided clues for application of eight extra Meridians theory to birth physiology. Second, the progressing birth physiology of modern medicine based on the importance of the brain function was examined, with which the application of eight extra Meridians and extraordinary organs theories to the birth process showed close relationship. Conclusion : The following conclusions could be drawn. In traditional publications of Korean Medicine, the contents explaining birth physiology with eight extra Meridians theory were scarce, mainly due to the doctor's perception of birth as part of the natural female physiology along with menstruation and pregnancy. However, the contents explaining menstruation, pregnancy, postnatal physiology and pathology through eight extra Meridians theory could be found in classical texts such as Neijing, Jebyeong-wonhuron, Imjeunginameuian. Therefore, it is reasonable to apply the eight extra Meridians theory to the birth process as well. Modern medicine's understanding that pituitary and hypothalamus hormones are in play on womb in the birth process, such as Oxytocin, is in continuous progress. Moreover, the environmental condition that has been traditionally known ideal to the birth process in both the East and West-dark, warm, quiet and secluded-is being confirmed in modern research. The application of eight extra Meridians theory to birth physiology can help to explain these modern information, and thus make them more acceptable.

  • This dissertation is try to figure out why chestnut belongs to kidney channel, from the viewpoint of five elements theory. After studying chestnut's property, flavor, channel tropism, main cure ability, prescriptions, shape, sweet, and prohibitions, I came to the following results. 1. Property of chestnut is warm and has no toxicity, so it is less related than kidney property. 2. Flavor of chestnut is salty and sweet, so it has some relation to kidney and spleen properties. 3. Channel tropism of chestnut enters mainly into kidney channel, and then spleen and stomach channels. 4. Chestnut controls kidney function of storing the essence of life, determining the condition of bone and marrow, conduction water metabolism, affecting reasoning activity, and controls activity of nine openings of body. It also has effects on functions of spleen, intestines and stomach. 5. Prescriptions including chestnut is similar to that of human brain, it is possible to reason out that chestnut has some relation to human brain. 7. As flavor of chestnut flower is similar to that of spermatic fluid, so it has som relation to kidney property. 8. As chestnut has property of blocking qi and it causes spleen, stomach and colon system to be confused, so it is suggested that persons with weakende spleen and stomach be not allowed to take in.

  • Walking can have a positive impact on cognitive function in adolescents. This study aimed to compare the effects of walking with sneakers and barefoot on cognitive ability in adolescents. Fifty-nine adolescent male students were included in the study and assigned to the control (n = 20), sneaker (n = 19), and barefoot (n = 20) groups. The barefoot and sneakers group performed a 40-min walking exercise four times a week for 12 weeks during the morning physical activity time, while the control group performed self-study. Electroencephalogram (EEG) and brain activity variables were measured before and after the exercise program. The results showed that after 12 weeks, the barefoot group had a significant decrease in Gamma and H-beta waves and a significant increase in sensorimotor rhythm (SMR) and Alpha waves. Conversely, the control group showed a significant decrease in SMR waves and increase in Theta waves. The sneaker group showed a significant decrease in SMR waves alone. In an eyes-open resting state, the barefoot group showed a significant increase in H-beta, M-beta, SMR, and Alpha waves. The barefoot group also had a significant increase in cognitive speed and concentration and a significant decrease in brain stress. Taken together, barefoot walking can effectively enhance cognitive ability in adolescents, as demonstrated by the significant variation in EEG activity. This research highlights the potential benefits of barefoot walking as a simple and effective form of exercise for enhancing cognitive function in adolescents.

  • There are several methods to implement the logical machine reasoning such as a frame theory and a production system of artificial intelligence. And these algorithms can explain the obtained result through the inference processes. However, emotional (KANSEI) patterns are not so easily implement. One of reason is that some emotional expression is the result of process from unconscious level to conscious level, and not easily identified the original unconscious causes. Therefore, a function of KANSEI database needs to structuralize unconscious level. Our approach is to develop the computerized counseling support system which can structuralize the unconscious brain functions from the view point of the psychology with focusing physiological and emotional responses. Especially, development of the algorithm that can form the network from unconscious to conscious using the image recollection is the application of the structured association technique (SAT). The developed system was implemented on the Web using CGI and emotional network database.

  • The inverse heat conduction problem (IHCP) is a problem of estimating boundary condition from temperature measurement at one or more interior points. Neural networks are general information processing systems inspired by the connectionist theory of human brain. By properly training the network by the learning rule, the neural network method can handle many non-linear or other complex problems. In this work, neural network is applied to complicated inverse heat conduction problems. Efficiency of the procedure is enhanced by incorporating the radial basis functions (RBF). The RBF is trained faster than other neural network and can find smooth solution. In order to demonstrate the effectiveness of the current scheme, a typical one-dimensional IHCP is considered. At one surface, the temperature as well as the heat flux is known. The unknown temperature of interest is estimated on the other side of the slab. The results from the proposed method based on RBF neural network are compared with the conventional method.

  • Based on the theory of cognitive reserve, we undertook this study to develop a cognitive function training program for woman in menopausal transition with complaints of declining in cognitive function. The program was established by applying the analysis, design, and development stages of the network-based instructional system designed by Jung. The cognitive function training program developed by us is an was an 8-week program composed of cognitive and video training using a mobile application. The program consists of 24 sessions, each with 20-30 minutes of duration, to be completed 3 sessions per week. The contents of the cognitive function training comprise of memory, attention, language function, and scenario-based problem-solving for executive functions, all of which are cognitive areas found to be the most vulnerable for menopausal women. The educational contents were developed for eight subject areas, one subject area per week, including the definition of menopause, its causes and symptoms, menopause and brain function, etc. During the pilot test, the cognitive function training program was applied to 10 menopausal women who complained of cognitive function decline. The results indicated that, after eight weeks of training, the overall cognitive function of participants increased, revealing statistically significant differences (t=-3.04, p=.014) after the program was completed. The mobile app-based cognitive function training program might not only improve patients' memory functions but also potentially reduce the incidence of dementia.

  • Objectives : The quotation of Seongyeong found in the chapter of danjeonyusam in Donguibogam uses a type of allocation of Gi(氣), Sin(神), and Jeong(精) each in Upper, Middle and Lower, three Danjeon, that is different from the type was widely accepted at the time. The paper attempts to interpret this in a new way. Methods : The paper collected the understanding of Jeong-Gi-Sin found in the Korean medicine based on Naedan Theory of Taoism, and tried to approach and structurally analyze the contents of Seongyeong, Ojinpyeonju, and Hwanggeuggyeongseseo found in Donguibogam's danjeonyusam. Results : The control of the body by Gi stored in Upper Danjeon is related to brain function, control of Gi at Lower Danjeon which preserves Jeong in Kidney is related to proliferation of Original Qi from kidney region throughout the body by triple energizers. Sin located at Middle Danjeon is contrasted with Jeong in Lower Danjeon, and Sin controls activity of life in the part between body and Gi. Conclusions : A new understanding on the assignment of Jeong-Gi-Sin in Seongyeong is possible, and it is expected to contribute to the future study of Korean Medicine and Taoism.

  • The intelligence is the capacity to recognize the things and implies the meaning of abstract thought, learning and adaptability to the circumstance. Recently, as the promotion of learning ablility and memory attracts many people's attention, many studies of this have been accomplished but the pharmacological methods could not promote the intelligence and memory. In oriental medical theory, the human body is composed of four elements - essence, energy, sprit, blood and among these elements, sprit is considered as the concept of vital energy and mind. Especially, from the Jang-Fu physiological point of view, the memory is closly related with the heart and kidney In oriental medicine, some experiments on animal and literature studies on the subject of memory promotion have done. But because of difference in memory mechanism between man and animal, it is not in reason to apply the result of experiment on animal to human. Therefore I have methodological study of memory promotion to set up the concept of oriental medicine and experimental theory about this and can obtain such conclusion. 1. The oriental medical therapy for memory promotion is following. nourishing the heart and blood, regulating the function of spleen, relieving the mental stress, reinforcing the heart and kidney, invigorating and enriching the blood. 2. The insufficient intelligence in a child is considered to not be full and in an old man, it is considered to decline by degrees. 3. It is needed to molecular biological study of neurotransmitter after the using of oriental medical therapy. 4. It is possible to study using the genetic mutation or observing the collateral of brain nerve cell.
