본 논문에서는 연속적인 입력화상에서 움직임을 나타내는 객체(Object)를 적은 연산량을 사용하여 추출해 내는 알고리즘을 소개한다. 본 알고리즘은 두 가지 단계로 이루어진다. 첫번째 단계로, 이전의 영상과 현재의 영상을 비교하여 움직임의 변화를 보이는 영역을 찾는다. 이 단계에서는 영상을 비교하여 움직임을 추출하기 위하여 창조영상과 현재의 영상, 그리고 영상의 데이터로서 edge정보를 사용한다. 두 번째 단계에서는, 첫번째 단계에서 움직임으로 판단된 Object mask(변화를 가지는 영역)를 가지고 background 제거 및 Object의 정확한 shape을 만들기 위한 post-processing과정을 가지게 된다. 이 두 단계를 거친 후 입력영상에서 background를 떼어낸 최종적인 Object의 shape정보가 추출되게 된다. 이 알고리즘은 object를 기반으로 부호화함으로써 데이터의 압축률을 극대화 시키는 MPEG-4뿐만 아니라, video database, 무선 통신등과 같은 다양한 범위의 application에 적절하게 사용될 수 있을 것이다.

This paper describes the application of a neural network based adaptive line enhancer (ALE) for enhancement of the weak QRS complex corrupted with background noise. Modified fully-connected recurrent neural network is used as a nonlinear adaptive filter in the ALE. The connecting weights between network nodes as well as the parameters of the node activation function are updated at each iteration using the gradient descent algorithm. The real ECG signal buried with moderate and severe background noise is applied to the ALE. Simulation results show that the neural network based ALE performs well the enhancement of the QRS complex from noisy ECG signals.

In the design of buildings, lateral loading is one of the most important factors considered by structural designers. The concept of performance-based design (PBD) is well developed for seismic load. Whereas, wind design is mainly based on elastic analysis for both serviceability and strength. For tall buildings subject to extreme wind load, inelastic behavior and application of the concept of PBD bear consideration. For seismic design, current practice primarily presumes inelastic behavior of the structure and that energy is dissipated by plastic deformation. However, due to analysis complexity and computational cost, calculations used to predict inelastic behavior are often performed using elastic analysis and a response modification factor (R). Inelastic analysis is optionally performed to check the accuracy of the design. In this paper, a framework for application of an R factor for wind design is proposed. Theoretical background on the application and implementation is provided. Moreover, seismic and wind fatigue issues are explained for the purpose of quantifying the modification factor R for wind design.

Background : Amygdalin is abundant in Armeniacae semen, and it is recently reported to treat cancers and relieve pain. But modus operandi of amygdalin at the level of neuron has not been reported, yet. Objective : This study aimed to find out the effect of amygdalin on glycine- and glutamate-induced ion currents in periaqueductal gray (PAG) neurons. And it was investigated that amygdalin participates in the regulation of the descending pain control system in the level of PAG neurons. Method : We investigated that the changes of glycine- and glutamate-induced ion currents in PAG neurons through application of lipopolysaccharides (LPS) and application of amygdalin with LPS by using the nystatin-perforated patch clamp method. Result : Application of LPS on PAG neurons resulted in increased glycine-induced ion current, and in decreased glutamate-induced ion current. In contrast, application of amygdalin with LPS resulted in decreased glycine-induced ion current increased by LPS, and increased glutamate-induced ion current decreased by LPS. Conclusion : Amygdalin from Armeniacae semen controls glycine- and glutamate-induced ion current by LPS in PAG neurons, and it is suggested that amygdalin participates in the regulation of the descending pain control system in the level of PAG neurons.

An international standard for the product model data, STEP, and a standard for the distributed object technology, CORBA, will play a very important role in the future manufacturing environment. These two technologies provide background for the sharing of product data and the integration of applications on the network. This paper describes a prototype CAD/CAE environment that is integrated on the network by STEP and CORBA. Several application servers and client software were developed to verify the proposed concept. The present CAD/CAE environments are composed of several individual software components which are not tightly integrated. They also do not utilize the rapidly expanding network and object technologies for the collaboration in the product design process. In the design process in a large organization, sharing of application resources, design data and analysis data through the network will greatly enhance the productivity. The integration between applications can be supported by two key technologies, CORBA(Common Object Request Broker Architecture) and STEP(Standard for the Exchange of Product Model Bata). The CORBA provides interoperability between applications on different machines in heterogeneous distributed environments and seamlessly interconnects distributed object systems. Moreover, if all the data in the CAD/CAE environment are based on the STEP, then we can exclude all the data conversion problems between the application systems.

Background: To compare pain perception during palatal injection administration in children aged 7-9 years while using pre-cooling of the injection site versus application of topical anesthesia as a pre-injection anesthetic during the six months. Method: A prospective randomized split-mouth crossover trial was conducted among 30 children aged 7-9 years, who received topical application of either a pencil of ice (test group) or 5% lignocaine gel (control group) for 2 min before injection. The primary and secondary outcome measures were pain perception and child satisfaction, measured by the composite pain score and the faces rating scale, respectively. Unpaired t-test was performed to determine significant differences between groups. Results: The test group had significantly lower pain scores for self-report and behavioral measures (P < 0.0001). The changes in physiological parameters at the baseline (P = 0.74) during (P = 0.37) and after (P = 0.88) the injection prick were not statistically significant. Children felt better by the pre-cooling method (P < 0.0001). Conclusion: Ice application using a pencil of ice for 2 min reduced pain perception significantly compared to the use of a topical anesthetic. Moreover, ice application was preferred by children.
