The electroacupuncture according to Voll(EAV) is a method of combining the fundamentals of classical acupuncture with the facilities of modern electronics for diagnostics and therapy. Classical acupuncture uses energy conducting lines called 'meridians' and acupuncture points situated along them. Dr. Voll is considered the founder of 'EAV' since he succeeded not only in finding a method of exact electric localization and in explaining the interelation between the acupuncture points and their individual organs, but he also succeeded in measuring the resistance of these points and in explaining the diagnostic meaning of the measured values. In the course of his research, Voll found numerous new measurement points and energy conducting vessels unknown to classical acupuncture, but indispensible for diagnosis of human organic functions. As a basis of modern research in meridian theory, I tried to compare EAV measurement point with classical acupuncture point.

Tuberculosis (TB) is one of the largest health problems in the world today. And the incidence of nontuberculous mycobacteria (NTM) lung disease appears to be increasing worldwide. Recently, an automated, nucleic acid amplification assay for the rapid detection of both Mycobacterium tuberculosis and rifampin resistance was developed (Xpert MTB/RIF). And fixed-dose combinations of anti-TB drugs and linezolid have been introduced in the treatment of TB. And new NTM species, named Mycobacterium massiliense, which is very closely related to Mycobacterium abscessus was reported. In this review, these recent advances in the diagnosis and treatment of TB and clinical characteristics of M. massiliense lung disease are discussed.

Concrete are brittle materials and they are which come to brittle fracture rapidly by progress of cracks. Therefore, what the time for repairing the damage portion is understands importantly by such cracks. When they happened the glass pipe similar to concrete was used. Such a glass pipe can insert repair material in an inside, or can use it by switch. They are interested in the crack monitoring of structure using FM radio sensor and PZT sensor. In this study, the monitoring to a crack was studied using FM radio sensor and PZT sensor. Therefore, the purpose of this study is the fundamental research which detects damages of main members using the compound sensor which consisted of the radio sensors of resistance, PZT, and FM system.

Eisenmenger syndrome is a condition which systemic arterial blood oxygen unsaturation occurs if obstruction in the pulmonary capillaries raises the pulmonary vascular resistance and pulmonary arterial pressure to or beyond systemic levels and then a significant right to left shunt develops across a preexisting cardiac septal defect or an aortopulmonary communication-We have experienced 3 cases of similar condition. Case I is 24 year old man who has had cyanosis and dyspnea on exertion since childhood. His pulmonary arterial pressure was 110/80mmHg. He was operated under diagnosis of the mitral stenosis and tetralogy of Fallot, but it was finally discovered that he had patent ductus arteriosus and ventricular defect was closed with perforated prosthetic patch, but the patient expired due to right heart failure low cardiac output. Case II was 16 year old female who had pulmonary hypertension of 110/85mmHg. She was diagnosed as Eisenmenger syndrome combining with atrial septal defect and patent ductus arteriosus. Case III was 20 year old male. His pulmonary arterial pressure was 110/70mmHg and the underlying defect was patent ductus arteriosus.

This paper reports the contamination performance of transmission line porcelain insulators tested under five different contaminant conditions - clean and ESDD (equivalent salt deposit density) level (A, B, C, and D) through measurement of their leakage current under drop of potential method. To estimate the contamination for transmission line porcelain insulators, leakage current waveform and its maximum value were measured under step-up power test. In the clean insulators test, % distortion factors decreased with increasing step-up power, and as the ESDD level increased, some characteristics such as frequency analysis, harmonics and % distortion facotor could be used for contamination diagnosis of the transmission line porcelain insulators.

The prevalence of obesity in Korean children is estimated to be around 10%, and has increased significantly over the past 20 years. Metabolic syndrome, which includes central obesity, glucose intolerance, insulin resistance, dyslipidemia, and hypertension, is a well documented risk factor for cardiovascular diseases, but there is no general consensus concerning its definition for children. In this study, ablut 30-40% of overweight or obese children had metabolic syndrome compared to less than 10% in the general population. Dyslipidemia was the most common component and hyperglycemia was the least common component of metabolic syndrome. If the prevalence of childhood obesity continues to increase, it is highly likely that the prevalence of the metabolic syndrome will also increase. These findings emphasize the importance of preventing obesity in addition to the diagnosis and management of metabolic syndrome in Korean adolescents.

A new live-line insulator tester was developed to detect faulty insulators in 154kV power transmission lines. This paper is the first part of the two-part paper and deals with its tester development. The developed tester has the following characteristics. First, it automates parts of the insulator inspection process by using a sensor and an actuator, and secondly, it sustains its weight by itself, not by a lineman. Finally, it measures the insulation resistance of an insulator together with its distribution voltage to provide more information for its analysis and diagnosis. These leads to the improvement of its operation efficiency, measurement reliability and usability. Its effectiveness was validated by live-line field tests in actual power lines.

DC link electrolytic capacitors are widely used in various PWM power converter system, such as adjustable speed driver(ASD) or DC/DC converter. Electrolytic capacitors, which is the most of the time affected by aging effect, plays a very important role for the power electronics system quality and reliability. This objective of this paper is to propose a improvement method to detect the rise of equivalent series resistor(ESR) in order to realize the online failure prediction of electrolytic capacitor for DC link of PWM power converter. The ESR detection scheme is based on the determination of the electrolytic capacitor AC losses calculated from voltage/current measurement using AC coupling. Therefore, the preposed online failure prediction method has the merits of easy ESR computation and circuit simplicity compare with BPF method. Simulation results show the veridity of the proposed on-line ESR estimation method.

Objectives: Epicardial fat is true visceral fat that is known to be associated with metabolic syndrome, high abdominal fat, insulin resistance, coronary artery diseases, low coronary flow reserve and subclinical atherosclerosis. Dampness-Phlegm pattern is one of the pattern diagnosis of traditional Korean medicine. Previous studies showed that Dampness-Phlegm pattern is associated with hypertension, dyslipidemia, metabolic syndrome. This study is intended to find association between Dampness-Phlegm pattern and epicardial fat thickness. Methods: This study was a community-based single center trial. Ischemic stroke patients within 30 days after their ictus were enrolled. Epicardial fat thickness was measured using transthoracic echocardiography. Other measured and obtained variables are medical history, weight, height, body mass index, fasting blood glucose, cholesterol, triglycerol, high density lipoprotein, lipid and low density lipoprotein. Results: Three hundred sixty six were enlisted, and one hundred forty were diagnosed with the Dampness-Phlegm pattern. Dampness-Phlegm pattern group had significantly thicker epicardial fat. Binary logistic regression also showed statistically significant result. Conclusions: This study showed close association between epicardial fat and Dampness-Phlegm pattern. This result suggests a clue to standardization of pattern identification.

Epidermal growth factor receptors (EGFRs/HERs) and downstream signaling pathways have been implicated in the pathogenesis of several malignancies including breast cancer and its resistance to treatment with chemotherapeutic drugs. Consequently, several monoclonal antibodies as well as small molecule inhibitors targeting these pathways have emerged as therapeutic tools in the recent past. However, studies have shown that utilizing these molecules in combination with chemotherapy has yielded only limited success. This review describes the current understanding of EGFRs/HERs and associated signaling pathways in relation to development of breast cancer and responses to various cancer treatments in the hope of pointing to improved prevention, diagnosis and treatment. Also, we review the role of breast cancer stem cells (BCSCs) in disease and the potential to target these cells.
