  • A 4-year-old male developed the esophageal perforation after air-gun shut injury in the thorax. The esophageal perforation was found on esophagogram at the next day after the accident. Because of delayed diagnosis, mediastinitis and pyopneumothorax were developed. The general conditions of the patient were very critical with sepsis on admission. Therefore, two staged operation was planned. At the first stage, exclusion and diversion of the esophagus was carried out to treat chemical pneumonitis due to gastric contents through the esophago-bronchial fistula by gastroesophageal reflux. Clinical conditions of the patient were improved after the first stage operation. At the second stage, the esophageal reconstruction with right colon was performed.

  • In general, the characteristics of plasma spray coating are strongly dependent on process conditions. In this paper, Mo and Co alloy coating layers were made by plasma spraying with different spray parameters and characterized using X-ray diffraction, scanning electron microscopy(SEM), hardnass test, and wear test. It was found that the coating characteristics were mainly affected by phase composition of the powder, spray distance, arc current, and gas flow rate.

  • The accurcy and the application limits of the Three-Curve Method(TCM) and Zonal Cavity Method(ZCM) are evaluated. Average illuminance values are calculated by TCM and ZCM for various lighting conditions using general Diffusing Luminaires and Direct Luminaires. These values are compared with the values from Monte-Carlo Simulation(MCS) for the same lighting conditions. Accuracy of MCS was proved by Moon's Analytical Method.

  • Inflatable panels made of modern and new textile materials can be inflated at high pressure to have a high mechanical strength. This paper is based on the finite element method as a general solution to determine the characteristics of deformed inflatable panels at high pressure in various end and loading conditions. Proposed method is based on the construction of weak form of formulation and application of Reduced Integration Element method (RIE) to solve the numerical problem of shear locking. The numerical results are validated as an outcome of comparison with other published results.

  • The influence of nonlinear phenomena on the behavior of stationary forced flexural-gravity waves on the surface of deep water is investigated, when the perturbation of external pressure moves with near-resonant velocity. It is shown that there are three branches of bounded stationary solutions turning into asymptotic solutions of the linear problem with zero initial conditions. For the first time ice sheet destruction by turbulent fluctuations of atmosphere pressure in ice adjacent layer in wind conditions is studied.

  • In this paper, we showed the erosion characteristics of MgO protector layer releated to lifetime of plasma display panel(PDP). We observed MgO erosion characteristic as a functions of deposition conditions. In RIE condition of Xe gas, the lowest erosion rate appears in the conditions of no heating, bias voltage -30V and pressure 5mtorr. In general. as deposition rate increases, erosion rate decreases.

  • This paper deals with the strong consistency of the asymmetric least squares for the nonlinear censored regression models which includes dependent variables cut off midway by any of external conditions, and provide the sufficient conditions which ensure the strong consistency of proposed estimators of the censored regression models. One example is given to illustrate the application of the main result.

  • In this paper we consider inverse problem for a general class of nonlinear stochastic differential equations on Hilbert spaces whose generating operators (drift, diffusion and jump kernels) are unknown. We introduce a class of function spaces and put a suitable topology on such spaces and prove existence of optimal generating operators from these spaces. We present also necessary conditions of optimality including an algorithm and its convergence whereby one can construct the optimal generators (drift, diffusion and jump kernel).

  • For recent years, several disputes between Korean consumers and multinational companies have arisen. Since the disputes were big and material that children's safety was at issue, a question started if Korean law properly has protected consumers' rights against multinational companies. While the Korean legal society tried to legislate punitive compensation with this concern, the U.S. Supreme Court reached an interesting case law regarding consumer contracts. A recent trend on consumer contracts in the United States shows that general terms have arbitration clause with class action waiver. As much as international arbitration has worked as the most effective resolution in international commercial disputes, the concept is still foreign and the experts are not approachable to lay individual consumers. However, class action in arbitration can hugely help for lay individual consumers to bring a case before arbitration tribunal. California courts consistently showed the analysis that the practical impact of prohibiting class action in arbitration clause is to ban lay individual consumers from fighting for their rights. However, the Supreme Court held that the arbitration clause shall be enforced as parties agree even if consumers practically cannot fight for their rights in the end. Even though consumer contracts are a typical example of lack of parity and of adhesive contract, the Supreme Court still applies liberalism that parties are equal in power and free to agree. This case law has a crucial implication since Korean consumers buy goods and services from the U.S. and other countries in everyday life. Accordingly, they are deemed to agree on the dispute resolution clauses, which might violate their constitutional right to bring their cases before the adjudication tribunal. This issue could be more important than adopting punitive compensation because consumers' rights are not necessarily governed by Korean law but by the governing law of the general terms and conditions chosen and written by the multinational companies. Thus this paper studies and analyzes the practical reality of international arbitration and influence of arbitration clause with class action waiver with the U.S. Supreme Court and California case laws.
