  • In the pharmacology of traditional Korean medicine, each drug has its own specific characters. The different characters of drugs are employed to treat diseases, rectify the hyperactivity or hypoactivity of yin or yang, and help the body restore its normal physiological functions, consequently curing the diseases and restoring health. The various characters and functions of these drugs concerning medical treatment include drugs' properties, flavours, actions of lifting, lowering, floating and sinking, channel tropism, toxicity, etc. Among these theories, theory of properties and flavours of drugs provides the basis for drug analysis and application. 'Property' refers to the cold, hot, warm or cool nature of a drug. These properties of drugs are so sorted out according to the different actions of the drugs on the human body and thier therapeutic effects. Drugs which cure heat syndrome(yang syndrome) have a cold or cool property, whereas drugs which cure cold syndrome (yin syndrome) have hot or warm property Drugs of cold and cool-natured and drugs of warm and hot natures are of opposite properties. A cold-natured drug is different from a cool-natured on only in degree, and so is a warm-natured drug from a hot-natured drug. Most of the cool- or cold- natured drugs have the effects of clearing heat, purging fire, removing toxic substances, and nourishing yin, and are uese to cure heat syndromes. On the contrary, drugs of warm or hot nature usually have the effects of dispersing cold, warming up the interior, supporting yang, and treating collapse, and are therefore used to treat cold syndromes. We thought that the property of drug may be related to the autonomic nervous system in western medicine. In other words, drugs of warm or hot nature increase heart rate or acts like sympathomimetics, and drugs of cool or cold nature decrease heart rate or acts like para sympathomimetics . According to this hypothesis, we administrated some drugs to isolated rat right atrium in magnus tube. But there is no correlation between 'property' in traditional Korean medicine and autonomic nervous system in western medicine.

  • Objective: This research measured physiological and psychological effects of Vibroacoustic stimulation(VA) to scapular and sacrum of supine position on the mattress. Background: When vibroacoustic stimulation applies to human body, it has a positive influence on physiological and psychological effects by stimulating the organs, tissues and cells of whole body. Method: This experiment was conducted to 10 normal males in two conditions: no stimulation and vibroacoustic stimulation. No stimulation experiment was executed as a supine position for 30 minutes without any vibrational stimulus, while vibroacoustic stimulation was transmitted by the vibrational speaker, which uses 40Hz frequency. Subjects had a laser Doppler flowmeter probe in scapular, sacrum, and also had 8 channel electroencephalogram(EEG) measurement sensor in the scalp. Blood pressure and skin temperature were measured in two conditions with an underlying posture for 30 minutes. Additionally, blood flow rate and EEG were measured before and after for two minutes on two conditions. Results: According to the vibroacoustic stimulation, blood flow rate and skin temperature were increased, while blood pressure was decreased. When using vibroacoustic stimulation compared to no stimulation, blood flow rate went approximately two times higher, and skin temperature also higher 3~4 times. Furthermore, the relative alpha power of brain wave was significantly increased when we applied to vibroacoustic stimulation. Conclusion: This experiment tested the VAT embedded in mattress in two conditions. According to this experiment, VAT decreases blood pressure, improves not only a physiological effect on blood flow rate as well as skin temperature, but also psychological functions by increasing relative alpha power. Application: The results of the publishing trend analysis might help physiological and psychological effects of vibroacoustic stimulation.

  • Purpose: The subcutaneous fat tissue is separated into 2 layers by the subcutaneous fascia: the superficial and deep fat layers. The two fat layers have different structures according to the body regions. The purpose of this study is to evaluate the distribution and pattern of the two fat layers in the human body by computed tomography (CT) and histological analysis according to age, sex, anatomical region, and body mass index (BMI). Methods: This study included 200 males and 200 females who underwent 64-channel dynamic CT in our hospital. The patients were divided into 5 groups according to 10 years of their ages separately in either male or female gender. The thickness of the superficial and deep fat layers was measured in the abdominal, pelvic, and femoral regions, and we analyzed the values. Statistical analyses were performed using SPSS software. The $3{\times}3$-cm whole fat layers were harvested from the same sites of 3 cadavers for histological examination, and one cadaver was dissected for gross evaluation. Results: The total thickness of subcutaneous fat tissue was greater in females than in males, and the ratio of the superficial fat layer to the whole fat layer was higher in females. The superficial fat layer became thinner with increasing age in males. As BMI increased, the total fat layer became thicker, and the superficial fat layer became thicker than the deep fat layer. On histological examination, the superficial fat layer had small adipose lobules and showed a densely distributed pattern in the abdominal region, whereas in the femoral region, it had large adipose lobules and showed a sparsely distributed pattern. There were no significant differences in the histological findings of the deep fat layer between the 3 body regions. Conclusion: Significant differences in histological findings of the two fat layers were found in relation to age, sex, anatomical region, and BMI. The superficial fat layer became thinner with increasing age in males, but it was constant in females. As BMI increased, the total thickness of subcutaneous fat tissue became greater, and the superficial fat layer became thicker than the deep fat layer. Our measurements can be used to understand the characteristics of the fat layers in relation to age, sex, anatomical region, and BMI.

  • The meridian system is the most essential and basic connecting structure that maintains the vital activities of viscera and bowels by connecting them with each part of body's surface. Doctors can understand the healthy condition, and the region and deficiency-excessiveness of disease by observing the condition of Qi flowing. Deficiency and excessiveness could be differentiated by various symptoms expressed in meridian system. Especially there could be several clues like pain, heat-cold, protuberance-depression, change of color and shine in the line of channel leads to the judgment of deficiency-excessiveness The diagnosis of deficiency and excessiveness can be generalized by quantification of elastic status in skin surface along the meridian system. By comparing data from measurement of elastic condition with those from traditional deficiency and excessiveness, it could be utilized for the development of oriental medicine. All biological activities in the human body are based on meridian system according to the oriental medicine. Also the meridian system is viewed as basic and essential structure connecting internal viscera and each part of body. The areas of expressed channel phenomena are muscle to bone, muscle to muscle and bone to bone. These areas are called depression where meridian system is present and any changing state on those points can be measured. It could be difficult in diagnosing the reaction of meridian system because doctor can depend on his own judgment. Therefore, it is necessary to quantify and indexate channel reactions. To quantify the channel reactions, specially manufactured instrument was used to quantify the protuberance and depression to differentiate the deficiency and excessiveness. The results follow as below; 1. The elastic index measurement by the equipment proved a pattern of agreement showing the values that ranged within standard deviation 0.05kgf/cm throughout the experiment except few cases' measurement in CV-17. 2. To evaluate the state of deficiency & excessiveness of elastic index measurements in frontal point, elastic index measurements in the front paint were compared to the elastic index measured surrounding the point within 2.5 cm. Such result of indexing procedure was closely matched to the concept of palpitation. 3. If the elastic index values in the surrounding front point closely located to the elastic index values in the front point, the judgement on the state of deficiency and excessiveness was delayed. Otherwise, it was judged as deficiency or excessiveness. 4. Out of total 12 cases of comparing the elastic index values to the elastic index values in the surrounding front point, Three to nine front points were judged as either in the state of deficiency or excessiveness. 5. Among the nine front points judged as either in the state of deficiency or excessiveness, Four cases were matched to the electric index measured by EAV that evaluating the internal organs by five different phases. If more clinical cases are accumulated, it is expected to systematically theorize and improve the concept of deficiency and excessiveness in the internal organs using the front point.

  • To improve $B_1$ homogeneity in high field MRI, the RF power is applied to the transmit array coil elements sequentially in the time-multiplexed way. Since only a single coil element is activated in a time-multiplexing slot, the global standing wave formation in the human body is greatly suppressed. The time-multiplexing slot width is on the order of micro seconds, hence, high-order-harmonic slices can be placed far from the transmit coil and simultaneous multiple slice selection can be avoided. The $B_1$ homogeneities of a birdcage coil and an eight-channel transmit array coil have been compared through finite difference time domain simulations. The simulation results indicate that the proposed technique can reduce the peak-to-peak $B_1$ inhomogeneity down to one fourth of the transmission with a birdcage coil on the central plane of the human head model at 3 T. The mimicking experiments at 3 T, eight separate experiments with a single coil element activated and image reconstruction by combining the eight images, also show promising results. It is expected that the proposed technique has some advantages over other $B_1$ improving methods in real practice since simple RF switching circuitries are only necessary and electromagnetic coupling between the coil elements is out of concern in its realization.

  • This paper intends to suggest the positive, ecological vision of sustainability in Karen Hesse's Out of the Dust that Billie Jo Kelby recovers herself through her readjustment of interior consciousness and outer environment in her tragic situations caused by the Dust Bowl. In spite of her desires for happiness and affluence of home, she loses her mother and brother, and her musical talent as a pianist, and lies in self-abandonment. But she finally raises up herself with her courage and patience, reconciliating with the nature and ameliorating the community by taking care of the devastated landscapes. Hence it is appropriate to approach the loss-recovery process of nature and consciousness with ecological solutions, The Dust Bowl breaks down human mind and body, and eventually leads to the situations of despairs and death. Hesse proposes the primary solution that humans should reconstruct their interior consciousness and participate in recovering the nature because humans are inevitably linked with nature. In this novel, the nature takes a dynamic and active role as a catalyst, reconciling the self with other humans and settling with the conflicting situations in history and culture. This verse novel as an active, self-ordering, and corrective process gives the more intense ecological message. As Hesse defines the setting of Dirty Thirties as a channel of energy, she creates the utmost effects of ecological process that human and environment are part of a total situation, representing the transactional formulation, each conditioned by conditioning to the other. Therefore Billie Jo takes her part as an interpreter and actualizes herself, understanding the nature with metaphor and symbol. Eventually Billie Jo realizes that she should rebuild her environment not out of the dust but in the dust, accepting the reality of Dust Bowl.

  • In terms of the bolt-leaf-hanges in Three-yum and Three yang I referd to successive medical books and many recent literatures on the basis of Huangjenegeong Somun Treatise on the Darting and meeting of Yin and yang, thus considerd concept of successive commentators about the bolt-leaf-hanges in Three-yum and Three yang and reconstructed and systeamtically arranged the bolt-leaf-hanges's interrelationship, yum-yang's relation and movement of six chnnel, and then studied there trinciple in all the universe apply the body and the process is operated by the bolt-leaf-hanges in the trinciples followed in human make his life adaption environment. The process is operated by the bolt-leaf-hanges in Three-yum and Three yang. The trinciples followed in. Firstly, Three-yum and Three yang is not dirrerentiate by many, middle, little of yum-yanggi's different function & role. Secondly, Three-yum and Three yang is negatively related white showing that there is the bolt-leaf-hanges relationship through space of Three-yum and Three yang. Through internal relationship of Three yum channel & Three yang channel, it can be proven that Three-yum and Three yang is in negative relation and through achieving the bolt-leaf-hanges relation in dimensional concept, it can be proven that it can actually be applied to human. Thirdly, by showing Three-yum and Three yang's the bolt-leaf-hanges relation is relation between Three yum & Three yang as well as negative relation, it can be shown that Three-yum and Three yang's the bolt-leaf-hanges activity is circular, and that it maintains itself through appropriate transformation. Fourth, understanding of Three-yum and Three yang's the bolt-leaf-hanges relationship and yum-yang Concern & six channer's activity has been varied. It means that the understanding is affected by socity, philosophical & research culture of the various times. The purpose has been to systematically arrange and diagnosing Three-yum and Three yang's the bolt-leaf-hanges and thus make up a fundamental for recognition. But, further study should be carried out on medical explanation on the bolt-leaf-hanges and interpretation and operation of the bolt-leaf-hanges in O-UnYukKiron.

  • WBAN(Wireless Body Area Network) operating around the human body aims at medical and non-medical service at the same time. and it is the short-range communication technology requiring low-power, various data rate and high reliability. Various studies is performing for IEEE 802.15.4, because IEEE 802.15.4 can provide high compatibility for operate WBAN among communication standard satisfiable these requirements. Meanwhile, in the case of coexisting many IEEE 802.15.4-based WBAN, signal interference and collision are the main cause that is decreasing data reliability. but IEEE 802.15.4 Standard does not consider about coexistence of many networks. so it needs improvement. In this paper, To solve about this problem, identify coexistence problem of IEEE 802.15.4-based WBAN by preliminary experiments. and propose a scheme to mitigate the reliability decrease at multiple coexistence WBAN. The proposed scheme can be classified in two steps. The first step is avoidance to collision on the CFP through improving data transmission. The second step is mitigation collision through converting channel access method. Proposed scheme is verified the performance by performing comparison experiment with Standard-based WBAN.

  • Emotion is composed of various feelings such as pleasure, sorrow, comfortability, and so on. The complicated process of the measurement has long been recognized as a major hindrance for the studies of emotion. Previously, individuals' emotion has mainly been measured by means of self-report, interview, EEG (electroencephalogram), ECG (electrocardiogram), EOG (electroculography), and body temperature. With thanks to nano/micro technologies, the possibility in the development of emotion-on-a-chip (EOC) has begun to be proposed. EOC will make it possible to analyze one's psychological status by taking a drop of blood. Discovery of emotional biomarkers in body fluids, understanding of the correlation between those biomarkers and the results from brain science are prerequisites to validate the EOC technology. In this paper, paper microfluidics are introduced as a good candidate for the EOC. As paper microfluidics is cost-effective and easy to use it is expected to be a useful device for the emotion measurement. We present the design and fabrication process for the simple paper-based microfluidic device and discuss the possible application in the field of measuring the human emotion.
