Characteistics of Charge Traps and Poling Behavior of Poly (Vinylidene Fluoride)
서정원,류균상,이호성,Seo Jeong Won,Ryoo Kun Sang,Lee Hoo Sung Korean Chemical Society 1985 Bulletin of the Korean Chemical Society Vol.6 No.4
Transient charging and discharging currents as well as space charge limited currents have been measured in biaxially stretched poly(vinylidene fluoride) film under various poling fields and temperatures. At low temperatures and short poling times, the I-V characteristics showed shallow trap behavior. When the current values extrapolated to the infinite time, the I-V characteristics indicate that the distribution of the trap energy levels is uniform or very broad. The abnormal suppression of current at higher poling voltages and the high discharge rate observed also in the same voltage range are attributed to the morphological changes due to dipole reorientation.

In this study, the procedures for the preliminary design of the turbo-shaft engine for the light multi-purpose helicopter are established. The engine specifications are determined through the performance analysis on the on-design and off-design conditions by the use of simulation program. In addition, the effect of humidity on the engine performance is examined by considering the change of the gas properties and characteristic maps due to moisture contents. The calculation results show that the engine power is reduced by the existence of moisture in working fluid.

Biomarkers are likely to be important in the study of various pulmonary diseases for many reasons. Research efforts in developing biomarkers and surrogate endpoints of lung diseases have resulted in the identification of new risk factors and novel drug targets, as well as the establishment of treatment guidelines. Government agencies, academic research institutions, diagnostic industries, and pharmaceutical companies all recognize the importance of biomarkers in new drug development and advancing therapies to improve public health. In drug development, biomarkers are used to evaluate early signals of efficacy and safety, to select dose, and to identify the target population. Identification of suitable end points not only would help investigators design appropriate clinical trials but would assist clinicians in caring for this patient population. Though the area of pulmonology has received much attention in the past decades, it still lags behind with regard to the development of biomarkers, particularly those of health effects and susceptibility. This review critically summarized several biomarker researches such as Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points (ECLIPSE) study with objectives of identifying the parameters that predict disease progression of COPD, as well as biomarkers that may serve as surrogate end-points.

Tracheal rupture is a rare complication of tracheal intubation, but may result in pneumothorax, mediastinal emphysema, subcutaneous emphysema and other serious outcomes. Risk factors associated with tracheobronchial rupture include multiple vigorous attempts at intubation, inexperienced operator, intubating stylets, tracheal abnormalities, overdistension of tracheal or bronchial cuff, repositioning of tube without deflating the cuff, chronic obstructive airway disease and vigorous coughing while being intubated. We report a case of tracheal rupture after using single lumen endotracheal tube. A 41-year-old, 53 kg, female was operated for a repair of anterior cruciate ligament under general anesthesia in other hospital. Two hours later after the end of operation, facial swelling, dyspnea and chest pain developed. Chest computed tomography showed mediastinal emphysema. She was transferred to our hospital and bronchoscopy showed a rupture at posterior part of membranous portion 2 cm proximal to carina. Trachea was repaired and she was discharged from the hospital without complication. (Korean J Anesthesiol 2007; 52: 123~6)
