To measure the depth and extension on the surface cracks of the stone monument, ultrasonic pulse velocity targeted at the Mulgyeseowon Stele in Changnyeong was used in this research. Additionally, to establish a long-term countermeasure of management and conservation for this stele, we have investigated the material properties and damage on it and have conducted a precise diagnosis by a variety of non-destructive techniques. Our research has revealed that stones of the stele are composed mainly of three rock types according to the parts of it, alkali-feldspar granite, gabbro and diorite. The result of the deterioration evaluation has occurred that cracks, which are observed from every direction in the body of the stele, are the significant factors to reduce structural stability. The ultrasonic velocity for an evaluation on the properties of the stele has revealed that the speed was high in the order of body, pedestal and crown. Furthermore, to understand the present condition and occurrences of the cracks which have measured in many different forms on the stele quantitatively, we have estimated from 0.6 to 24.1cm deep of the cracks by To-Tc method using ultrasonic velocity.

Purpose: During the pelvic radiation therapy, it is performed with controlling bladder volume because the range of irradiation is changed depending on the bladder volume. Therefore in this study, we evaluate the accuracy of BVI by tracing the change of bladder volume using ultrasonic pulse diagnosis equipment(BVI 6100, Medical supply Co. LTD) Material and Methods: From January 2017 to September 2018, 19 patients who received pelvic radiation therapy at Pusan National University Hospital were included. To treat the patient, we compared that the bladder volume obtained from the BVI and the bladder volume obtained from the CBCT image then we evaluated for significance. Results: There was a significant correlation of r=0.773, BVI and CBCT in the whole volume section. However, based on the bladder volume in the RTP Image the p value was shown to be 0 at 125~175cc and lower than 0.05 at 175~275cc, And more than 0.05 at 275~375cc. Conclusions: In this study, the patient whose bladder volume is above than 275cc, there is a significance of bladder volume between BVI and CBCT image. However, we could make a decision to be undermined the reliability of BVI measurement in the case of the patient with emptied his urine. Therefore, it is possible to acquire a significant value for 175~275cc patients to use the correction value of BVI and the appropriate tolerance of volume.

A 1.86 kg, 3-year-old, female, Maltese was presented to the Veterinary Medical Teaching Hospital of Seoul National University after being hit by a car. The patient was diagnosed with urinary bladder rupture, diaphragmatic hernia and fracture of ilium, tibia and fibula. Repair surgery was performed after stabilizing treatment. During the surgery, hypoxia was identified and it worsened after positive pressure ventilation (partial pressure of oxygen in arterial blood ($PaO_2$): 52 mmHg, pulse oximetry ($SpO_2$): 87%, arterial hemoglobin oxygen saturation ($SpO_2$): 85.8%). In addition to hypoxia, blood pressure decreased to 30 mmHg. Positive pressure ventilation was discontinued because hypoxia and hypotension were aggravated. After suturing the diaphragm, air was withdrawn to form negative pressure within the thorax. However, negative pressure was not attained despite continuous withdrawal of air. A thoracostomy tube was placed because tension pneumothorax was strongly suspected. The patient recovered through close monitoring with the tube for 3 days. Due to limitation of evaluation of the lung, predicting occurrence of tension pneumothorax is difficult in patient of diaphragmatic hernia. Therefore, it is recommended that indicators of tension pneumothorax should be closely monitored during diagnosis and repair procedures of diaphragmatic hernia.

After a comparative study on between Shanghanlun(傷寒論) and Sa-sang constitutional medicine(四象醫學) in Pathogenesis, I got a conclusion like this. Sa-sang consitutional medicine(四象醫學) changed the directions to the medicine in the center of personality from the medicine in the center of Shanghanlun(傷寒論)'s demonstration, devided the personality of people by the size of Organ system(臟腑) into 4types of Tae-eum, Yo-yang, Tae-yang, Yo-eum(太少陰陽), and explains all the course of physiology, pathology, diagnosis, therapy of the body on the point of constitutional view. Comparing the features of two medicines, Shanghanlun(傷寒論) and Sa-sang constitutional medicine(四象醫學), Shanghanlun(傷寒論) devided the diseases into the three type of eum-yang based on eight principal syndroms(八綱原理), in accordance with evidence of illness, pulse and studied the therapy, Shanghanlun(傷寒論) set up the basis of medicine which is based on overall of symptoms and signg(辨證論治醫學). Sa-sang constitutional medicine(四象醫學) distinguished the image(象) which is devided by the size of inherited Organ system(臟腑), refered to the symptom of diseases(病症) and decided the therapic directions. So Sa-sang constitutional medicine(四象醫學) gave more accuracy to the therapy by subdeviding the process of differenciation of case(辨證) into 2 steps of differenciation of image(辨象) and differenciation of case(辨證). In view of etiologic factor, Shanghanlun(傷寒論) regarded it as a invading of pathogenic factors(邪氣), so Shanghanlun(傷寒論) has the medical theory of pathogenic factors(邪氣). But Sa-sang constitutional medicine(四象醫學) regarded it as a disorder of the genuine energy(正氣)'s movements(升降緩速), so Sa-sang constitutional medicine(四象醫學) has the medical theory putting first of genuine energy(正氣). But Shanghanlun(傷寒論) also recognized the constitutional difference basically and Sa-sang consitutional medicine(四象醫學) devided the constitution into Tae-eum, Yo-yang, Tae-yang, Yo-eum(太少陰陽) and explained the food-air-fluid metabolism(飮食-氣液之氣病證) as cold-hot, cool-warm and devided the the symptom of diseases(病症) into the interior and the exterior(表裏) as the up-down, slow-fast movements of eum-yang and insufficiency and excessiveness is between them. In the end, Sa-sang constitutional medicine(四象醫學) has the theory of eight principal syndroms(八綱原理) faithfully which is the theory of differenciation of case(辨證理論) of Shanghanlun(傷寒論). Therefore Shanghanlun(傷寒論) made a lot of influence on originating Sa-sang constitutional medicine(四象醫學), Sa-sang constitutional medicine(四象醫學) is the theory which is based on existing medical theory including Shanghanlun(傷寒論) and composed the new medical theory to the constitutional point of view. Sa-sang constitutional medicine(四象醫學) enriched the medical theory and developed the clinical medicine so it has the historical value in the medicine.

Background: Bronchoalveolar lavage (BAL) is a necessary procedure for diagnosis of various lung diseases. High-flow nasal cannula (HFNC) oxygen delivery was recently introduced. This study aimed to investigate the safety and effectiveness of HFNC oxygen supply during BAL procedure in patients with acute respiratory failure (ARF). Methods: Patients who underwent BAL while using HFNC at a partial pressure of oxygen in arterial blood/fraction of inspired oxygen ($PaO_2/FiO_2$; PF) ratio of 300 or below among patients who had been admitted from March 2013 to May 2017 were retrospectively investigated. Results: Thirty-three BAL procedures were confirmed. Their baseline PF ratio was $166.1{\pm}46.7$. $FiO_2$ values before, during, and after BAL were $0.45{\pm}0.12$, $0.74{\pm}0.19$, and $0.57{\pm}0.14$, respectively. Flow (L/min) values before, during, and after BAL were $26.5{\pm}20.3$, $49.0{\pm}7.2$, and $40.8{\pm}14.2$, respectively. Both $FiO_2$ and flow during and after the procedure were significantly different from those before the procedure (both p<0.001). Oxygen saturation levels before, during, and after BAL measured by pulse oximeter were $94.8{\pm}2.9$, $94.6{\pm}3.5$, and $95.2{\pm}2.8%$, respectively. There were no significant differences in oxygen saturation among the three groups. Complications of BAL procedure included transient hypoxemia, hypotension, and fever. However, there was no endotracheal intubation within 24 hours. Baseline PF ratio in "without HFNC" group was significantly higher than that in "with HFNC" group. There were no differences in complications between the two groups. Conclusion: The use of HFNC during BAL procedure in ARF patients was effective and safe. However, there were no significant differences in oxygen saturation level and complications comparing "without HFNC" group in mild ARF. More studies are needed for moderate to severe ARF patients.

A 47-year-old-man was admitted to the emergency department with dyspnea, right pleuritic pain, and high fevers for 3 days. He had a nonproductive cough that exacerbated the chest pain. A clinical examination revealed distressed and slightly tachypneic patient, with blood pressure of 110/90 mmHg, temperature of $39^{\circ}C$, pulse of 90 beats/min, respiratory rate of 24 breaths/min. A chest examination showed significantly diminished breath sounds in the right lung with dullness to percussion. Laboratory investigation demonstrated leukocytosis and a raised C-reactive protein. The results of arterial blood gas analysis revealed moderate hypoxemia. A radiograph and a CT scan of the chest showed extensive consolidation with multifocal low densities, and pleural effusion in the right lung. A diagnostic thoracentesis revealed straw-colored fluid, which was found to be a neutrophil-predominant exudate. At 7 days after admission, the clinical symptoms had not improved and the temperature was still $39^{\circ}C$ despite the aggressive therapy of community-acquired pneumonia. After comprehensive history taking, we realized then that he accidentally aspirated kerosene while siphoning from fuel tank to put into the boiler 3 days ago. Bronchoscopy with bronchial washings could be successful in establishing the diagnosis of hydrocarbon pneumonitis by demonstration of a high lipid-laden macrophage index. Thereafter, the symptoms and radiographic opacities gradually improved, and he was discharged several days later.

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.

After more than 10 years construction, KSTAR (Korea Superconducting Tokamak Advanced Research) had finally completed its assembly in June 2007, and then achieved the goal of first-plasma in July 2008 through the four month's commissioning. KSTAR was constructed with fully superconducting magnets with material of $Nb_3Sn$ and NbTi, and their operation temperatures are maintained below 4.5K by the help of Helium Refrigerator System. During the first-plasma operation, plasmas of maximum current of 133kA and maximum pulse width of 865ms were obtained. The KSTAR Integrated Control System (KICS) has successfully fulfilled its missions of surveillance, device operation, machine protection interlock, and data acquisition and management. These and more were all KSTAR commissioning requirements. For reliable and safe operation of KSTAR, 17 local control systems were developed. Those systems must be integrated into the logically single control system, and operate regardless of their platforms and location installed. In order to meet these requirements, KICS was developed as a network-based distributed system and adopted a new framework, named as EPICS (Experimental Physics and Industrial Control System). Also, KICS has some features in KSTAR operation. It performs not only 24 hour continuous plant operation, but the shot-based real-time feedback control by exchanging the initiatives of operation between a central controller and a plasma control system in accordance with the operation sequence. For the diagnosis and analysis of plasma, 11 types of diagnostic system were implemented in KSTAR, and the acquired data from them were archived using MDSpius (Model Driven System), which is widely used in data management of fusion control systems. This paper will cover the design and implementation of the KSTAR integrated control system and the data management and visualization systems. Commissioning results will be introduced in brief.

Research on condition monitoring and diagnosis of power facilities has been conducted to improve the safety and reliability of electric power supply. Although insulation diagnostic techniques for unit equipment such as gas-insulated switchgears and transformers have been developed rapidly, studies on monitoring of cables have only included aspects such as whether defects exist and partial discharge (PD) detection; other characteristics and features have not been discussed. Therefore, this paper dealt with PD characteristics against void sizes and positions, and with defect localization in XLPE cable. Four types of defects with different sizes and positions were simulated and PD pulses were detected using a high frequency current transformer (HFCT) with a frequency range of 150kHz~30MHz. The results showed that the apparent charge increased when the defect was adjacent to the conductor; the pulse count in the negative half of the applied voltage was about 20% higher than that in the positive half. In addition, the defect location was calculated by time-domain reflectometry (TDR) method, it was revealed that the defect could be localized with an error of less than1m in a 50m cable.
