In Sasang constitutional medicine, I have researched the process of visceral structure in the Eight Constitutionals under circulation of the five elements and the formation of primary source of illness. From this research, I could draw following conclusions through combination of the auxiliary psycho-formulas by applying the constitutional acupuncture therapy on the five elements diagnostic calculation. Since the arrangement for the five dimensions of organs in the eight constitutions has been formulated by circulation of the five elements in Sasang constitutions, if the five elements begin circulating count-clockwise from the reference point at the organs in Sasang constitutional medicine, the positive constitutional arrangement of organs is built up such as, the positive constitution of metal, earth, wood and water, while begin circulating clockwise, the negative constitutional arrangement of organs is formulated, such as the negative constitutions of metal, earth, wood and water. The source of illness results from imbalance of the organic force being generated by transfer of the five elements from compatibility to incompatibility when the five elements circulate. Hence, it has been acknowledged that if the source of illness comes from the strongest organ, it is the time when circulation of the five elements progresses from the second organ (the second strongest) in incompatibility, and if the source of illness comes from the weakest organ, it is the time when circulation of the five elements progresses from the third organ (the middle) in incompatibility. It is considered proper to diagnose meridians of the pericardium and the Triple Burners rather than to diagnose meridians of the heart and the small intestine which forms the visceral arrangement of the eight constitutions. For instance, the auxiliary psycho-formula obtains its prescription by attenuating the first organ (the strongest) while augmenting the fourth organ (the second weakest) when the axis of incompatibility in the five elements circulation crosses the second and the third organs, and it gets its prescription by attenuating the second organ(the second strongest) while augmenting the fifth organ(the weakest) when the axis of incompatibility in the five elements circulation crosses the third and the fourth organs. In addition, when medicating, the $4{\sim}5$ times of repeated performance can be assumed to represent the amount of an energy that each organ bears depending on the phase in the arrangement of the eight constitutional organs.

The stability constants, K for the complexation of alkali metal cations(Li^+, Na^+, K^+, Rb^+, and Cs^+) with both 4,5: 13,14-dibenzo-6,9,12-triaza-bicyclo [15,3,1] heneicosa-1 (21),7,19-trioxa-2,16-dione (DBPDA) and 6,9,12-trioxa-3,15,21-triaza bicyclo [15,3,1] heneicosa-1 (21),17,19-triene-2,16-dione (PDA) in N,N-Dimethylformamide (DMF) were determined conductomatically at various temperatures. At all the experiment temperatures, the K value sequences of the alkali metal ions with DBPDA and PDA are Cs^+ > K^+ > Rb^+ > Li^+ > Na^+ and Cs^+ > K^+ > Rb^+ > Li^+ > Na+, respectively. The K values for DBPDA are larger those of PDA for alkali metal ions. The widely recounted "hole-size-selectivity" principle is not applicable to these complexation systems. From the K values obtained at different temperatures, {\delta}H and T{\delta}S for these complexation reactions were determined. The enthalpy change plays principal important role in the complex formation by DBPDA. However, in the case of PDA, the entropy change also contributes to its complex formation.

In order to drive a hybrid propulsion device which combines an engine and an electric propulsion unit, battery packs that contain dozens of unit cells consisting of a lithium-based battery are used to maintain the power source. Therefore, it is necessary to more strictly manage a number of battery cells at any given time. In order to manage battery cells, generally voltage, current, and temperature data under load condition are monitored from a personal computer. Other important elements required to analyze the condition of the battery are the internal resistances that are used to judge its state-of-health (SOH) and the open-circuit voltage (OCV) that is used to check the battery charging state. However, in principle, the internal resistances cannot be measured during operation because the parallel equivalent circuit is composed of internal loss resistances and capacitance. In most energy storage systems, battery management system (BMS) operations are carried out by using data such as voltage, current, and temperature. However, during operation, in the case of unexpected battery cell failure, the output voltage of the power supply can be changed and propulsion of the hybrid vehicle and vessel can be difficult. This paper covers the implementation of a high safety battery management system (HSBMS) that can estimate the OCV while the device is being driven. If a battery cell fails unexpectedly, a DC power supply with lithium iron phosphate can keep providing the load with a constant output voltage using the remainder of the batteries, and it is also possible to estimate the internal resistance.

Recently, the protection coordination method of DC systems has been presented because renewable energy and distributed resources are being installed and operated in distribution systems. On the other hand, it is difficult to detect ground faults because there is no significant difference compared to a steady-state current in ungrounded IT systems, such as DC load networks and urban railways. Therefore, this paper formulates the detection principle of IMD (Insulation Monitoring Device) to use it as a protection coordination device in a DC system. Based on the signal injection method of IMD, which is analyzed by a wavelet transform, this paper presents an algorithm of detecting ground faults in a DC system in a fast and accurate manner. In addition, this paper modeled an IMD and an ungrounded DC system using the PSCAD/EMTDC S/W and performed numerical analysis of a wavelet transform with the Matlab S/W. The simulation results of a ground fault case in an ungrounded DC system showed that the proposed algorithm and modeling are useful and practical tools for detecting a ground fault in a DC system.

This study is concerned with examining the causes and symptoms of Woman various diseases and clearing up the situations of pulses and their treatment. Woman various diseases are said to be various kinds of diseases including the disorder of menstruation and genitals except pregnancy and postpartum diseases. The main contents are the penetration of heat into worm, the discharge of much blood, stomachache, and the postpartum cyst diseases. Among them, the nature of the diseases which often occur in the gynecology, such as the menstrual diseases and stomachache, were described comparatively in detail. The reason why heat penetrates into the worm is that the external germs come into it under its weakness. To treat it, heat should be removed and lumping blood should be sent out of body. Especially only after whether the disease is serious or not is examined, and just after the process of the disease is examined, the lumping blood can be eliminated. The ways to cure it by sweating a patient too much, getting him or her to vomit, or forcing him or her to be urinated too much, should be avoided. The disorder of menstruation, as the disease which most often occur among the diseases of gynecology, includes menstrual irregularity and blood discharge, and non-menstruation. Among them, non-menstruation and blood discharge are comparatively often discussed. When they are treated, lumping blood and cold energy should be cured well through getting rid of the lumping blood and making the blood vessel flow well. The difficult urination after childbirth, which comes from the weak urinary cist, makes symptoms such as the stuffy chest, the difficulty of lying down, and breathing with his or her back something. To urinate better, the ability of the urinary cist should be supplemented and improved. The principle of the treatment for Woman various diseases is to examine the situation of the pulse closely, then set up the way to treat it, and prescribe a patient. In this study, besides the treatment of Chinese herb medicine, the medicine for washing genitals and the medicine placed in the worm were used to cure Woman various diseases. This treatment is the beginning of the surgical treatment in the gynecology.
Purpose: All acts which are enforced from the radioactive iodine therapeutic team is a in its own way principle and provision. Therefore unification of all acts can not be appropriately. We will make the standard coherence. Materials & Methods: From 5 November, 2007 to 17 November 2007, we conducted a questionnaire survey of the nuclear medicine manager of 30 hospitals. The contents of a questionnaire is medical treatment section, patient management, prosecuting attorney section, waste management and safety supervision in about the patient and a questionnaire was drawn up in the method which selects an item. Results: 30 hospital agencies are operating purely for I-131 high dose ablation therapy. Diagnostic study and daily schedule had the difference of some. The most of education for the patients took charge of doctor and nurse. The satisfaction of education was evaluated as the high thing. The safety supervision of waste management accomplishment and Safety supervision the patient and the worker observed on the basis of atomic energy law. Conclusion: Specific standards with sufficient amount of information and practical contents should have been presented through the following data. However, it seems to be lacking in many aspects. Nevertheless, respondents rated 70.9%, which is relatively high, on the value of clinical utilization, and I am very thankful for the evaluation. For many years from now, it may seem necessary for a lot of research on the specific matters based on these data to be conducted.
Design prototype is described from the stately aspect as a principle of formative art, and from the shapeable aspect of physical feature. The prototype can be a common denominator which is contained in one nation's culture, art and life, as the thing which corresponds to the daily industrial craft, architecture and art's production intention and activity with the thought and background of the culture. We have formed the design prototypes with time and space in the process which absorbs and integrates the new culture. Modern Korean design's prototype can be seen in the late Chosun. As the upper culture and sub-culture were combined, the active culture was developed. Nobody can deny that Chosun's culture and art becomes a basis of today's design and Korea's beauty. In creating the design prototype, the natural environmental factors such as topography and climate are the most important. Such natural environmental factor led the design recognition of art and craft art, as well as an architecture and indoor environment's form. Korea design produced the artisan sprite which is devoted to a moral duty and instinct as our nation's nature and emotion, and ensured the emotional process not the rational process. So, it created naturalism which accepted the material and shape. Our design prototype's path tracking as an energy of future society's new design identity, can be the important theme for our design development.
Several investigators have presented the effects of external magnetic fields on the dose distributions for clinical electron and photon beams. We focus the low energy electron beam with more lateral scatter In this study we calculated the beam profiles for an clinical electron beam of 6 MeV with longitudinal magnetic fields of 0.5 T-3.0 T using a Monte Carlo code. The principle of dose enhancements in the penumbra region is to deflect the laterally scattered electrons from its initial direction by the skewness of the laterally scattered electrons along the direction of magnetic field lines due to Lorentz force under longitudinal magnetic field. To discuss the dose enhancement effect on the penumbra area from the calculated results, we introduced the simple term of penumbra reduction ratio (PRR), which is defined as the percentage difference between the penumbra with and without magnetic field at the same depth. We found that the average PRR are 33%, and 49% over the depths of 1.5 cm, 2.0 cm, and 2.4 cm for the magnetic fields of 2.0 T and 3.0 T respectively. For the case of 0.5 T and 1.0 T the effects of magnetic filed were not observed significantly. In order to obtain the dose enhancement effects by the external magnetic field, we think that its strength should be more than 2 T approximately. We expect that the PRR would be saturated to 50-60% with magnetic fields of 3 T-5 T As a result of these calculations we found that the penumbra widths can be reduced with increased magnetic fields. This Penumbra reduction is explained as a result of electron lateral spread outside the geometrical edges of the beam in a longitudinal magnetic field. This means that the electron therapy benefits from the external magnetic fields.
In connection with the safe storage of high level nuclear waste, effect of $H_2O$$_2$ on the corrosion behavior of 304L stainless steel was examined. Open circuit potentials and polarization curves were measured with and without $H_2O$$_2$. The experimental results show that $H_2O$$_2$ increased corrosion potential and decreased pitting potential. The passive range, therefore, decreased as $H_2O$$_2$ concentration increased, indicating that pitting resistance was decreased by the existence of $H_2O$$_2$ in the electrolyte. These effect of $H_2O$$_2$ on corrosion of 304L stainless steel are considered to be similar to those of ${\gamma}$-irradiation. To compare the effects of $H_2O$$_2$ with those of $O_2$, cathodic and anodic polarization curves ore made in three types of electrolyte such as aerated, deaerated, and stirred electrolyte. The experimental results show that the effects of $H_2O$$_2$ on the corrosion behavior were tory similar to those of $O_2$ such as increase of corrosion potential, decrease of pitting resistance, and increase of repassivation potential. In acid and alkaline media, the corrosion potential shifts by $H_2O$$_2$ were restricted by the large current density of proton reduction and by the le Chatelier's principle respectively.y.

Objective : The purpose of this study was to investigate the effect of Ayres's sensory integration (ASI) intervention on the sensory processing ability and motor development in children with Developmental Delay. Methods : 9 children in the experimental group and 8 children in the control group participated in this study for Developmental Delay children aged 3-5 years. For research tool, the Short Sensory Profile (SSP), Peabody Developmental Motor Scale-2 (PDMS-2) are used. In the experimental group, individual sensory integration therapy according to principle of ASI was performed for twice a week, 40 minutes, and 16 times for 8 weeks. Methods for the data analysis included Mann Whitney U test, Chi-square test, Wilcoxon's signed rank test, Cohen's d test of SPSS 24.0. Results : In the ASI Intervention group, the sensory processing ability showed statistically significant difference in total score, movement sensitivity, auditory filtering and low energy/weak compared to the control group without ASI intervention (p<.05). In the ASI Intervention group, the motor development showed statistically significant difference in Gross Motor Quotient, Fine Motor Quotient and Total Motor Quotient compared to the control group without ASI intervention (p<.05). Conclusions : In this study, ASI intervention had a positive effect on the sensory processing and motor development in children with Developmental Delay.
