The marriage between music and film, both temporal art forms, demands that the inherent aspects of note in each medium are brought into correspondence within a dramatic context. In film-making, the most crucial and difficult problem a film composer faces is finding the music that seems absolutely right for the film and its characters, sequences and dramatic lines. When writing a film score, composers become musical dramatists; some have a special instinct that enables them to find the right kind of melodic line, orchestral texture, rhythmic device and musical style to bring out what they intuitively recognize as the essential aspect of the drama. In this study, several examples are cited - Alex North, Hugo Friedhofer, Bernard Herrmann and David Raksin - that underline this kinetic function of music in film. Effort is made to uncover as many possibilities as possible, so as to arrive at a better understanding of how the two media interrelate for the purpose of emphasizing the dramatic lines.

CFD simulation was peformed for 2D and 3D flying and rotating frisbees. Multiple reference method(MRF) was utilized to consider the rotation of 3D model. Geometry change of 2D model shows dramatic increase of lift, but 3D simulation results for geometry change show decrease of lift and drag. Ground effect increases the lift of the frisbee being close to ground.

This paper suggests an algorithm to measure low-level radiation by radiation measuring devices, and the other algorithm to improve reaction speed of the device to better respond to dramatic changes in radiation amount. The former algorithm to improve the accuracy of measuring low-level radiation takes advantage of a dual window radiation measurement method which is based on accumulated average of pulses gathered by a radiation measuring sensor. The latter algorithm is to enhance reaction speed of a measuring device to more sensitively react to dramatic changes in radiation amount by adopting a dual window radiation measurement method which analyzes data patterns newly put into for six seconds. To verify the suggested algorithms, a hardware-which consists of sensor and high-voltage generator, controller, charger and power supply circuit, wireless communication part, and display part-was used. Tests conducted on the dual window radiation measurement method as used in the suggested algorithm have proved that accuracy improves to measure low-level radiation of 5uSv/h, and linearity also gets better. Other tests were conducted to see whether the suggested algorithm enhances the reaction speed of a radiation measuring device so that the device responds better to dramatically changing radiation amount. The experimental results have shown meaningful changes in numbers after six seconds. Therefore, the conclusions are made that the algorithm enhances the reaction speed of the device.

Blue-light-emitting peiymer/dielectric nanolayer nanocomposites were prepared by the solution intercalation method and employed in electroluminescent device. Their photoluminescence and electroluminescence characteristics suggested that the nanolayers isolate the polymer chains and hinder the formation of excimers and aggregates. By reducing the excimer formation and its deleterious effects on emission efficiency, both the color purity and the luminescence stability were improved. Furthermore, the dielectric nanolayers have an aspect ratio of about 500 and therefore act as efficient barriers to oxygen and moisture diffusion, which produced a dramatic increase in the device stability.

The two dimensional electron gas system based on GaAs/$Al_xGa_{1-x}As$ heterostructure is widely used for fabricating quantum structures such as quantum dot, quantum point contact, electron interferometer and so on. However the conductance of the device is usually unstable due to the presence of random telegraph noise in the device. To overcome such problem, we have studied the effect of surface state on the stability of the device by altering the surface state of the device with oxygen plasma. The dramatic improvement of the device stability has been observed after cleaning the device surface with oxygen plasma (by 50 W~120 W plasma power) for 30 sec followed by etching in HCl : $H_2O$ (1 : 3) solution.

As complementary metal-oxide semiconductor (CMOS) continues to scale down deeper into the nanoscale, various device non-idealities cause the I-V characteristics to be substantially different from well-tempered metal-oxide semiconductor field-effect transistors (MOSFETs). The last few years witnessed a dramatic increase in nanotechnology research, especially the nanoelectronics. These technologies vary in their maturity. Carbon nanotubes (CNTs) are at the forefront of these new materials because of the unique mechanical and electronic properties. CNTFET is the most promising technology to extend or complement traditional silicon technology due to three reasons: first, the operation principle and the device structure are similar to CMOS devices and it is possible to reuse the established CMOS design infrastructure. Second, it is also possible to reuse CMOS fabrication process. And the most important reason is that CNTFET has the best experimentally demonstrated device current carrying ability to date. This paper discusses and reviewsthe feasibility of the CNTFET's application at this point of time in integrated circuits design by investigating different types of circuit blocks considering the advantages that the CNTFETs offer.

Most stage directors and designers make use of controling and moving lots of stage set or device as a large automation device or machine to achieve dramatic effect in their performances. Specially, it is very important to use a programmable multi-chain hoist system which is able to move high speed as well as to lift heavy loads. This paper proposes a multi chain hoist servo system to lift or lower a heavy load of about l ton for public performances' stage. It is automatically operated, electrically driven by a control console with a PTP trajectory generation algorithm, a realtime network control algorithm, and 4 step sequential safety algorithm. The efficiency and performance of the developed system are verified through a series of experiments.

The stage manager role of "Our Town"(1938), a representative work of Thornton Wilder(1897-1975), is a unique theatrical device that presents a wide range of interesting and diverse perspectives in the actor's acting approach, the director's stage-shape methodology, and the audience's theater experience. Why did Wilder call stage manager role a stage manager, not just a simple narrator? Because "Our Town" intentionally lacks the basic elements that dramas must have, it needed a more self-reliant and omnipotent role in creating the margins of dramatic writing, including boldly omitted time and space, with infinite imagination. For this reason, stage manager role plays a much more complex and multi-functional role than a narrator. In response, this paper accurately articulates the concept of theatrical style and theatrical convention on the premise of the stage manager role in "Our Town," followed by making theatrical convention, the director of scene progress and scene change, the messenger of the writer's thoughts, and dramatic rhythm control.

The populations of Asian countries are expected to age rapidly in the near future, with a dramatic increase in the number of heart failure (HF) patients also anticipated. The need for palliative and end-of-life care for elderly patients with advanced HF is currently recognized in aging societies. However, palliative care and active treatment for HF are not mutually exclusive, and palliative care should be provided to reduce suffering occurring at any stage of symptomatic HF after the point of diagnosis. HF patients are at high risk of sudden cardiac death from the early stages of the disease onwards. The decision of whether to perform cardiopulmonary resuscitation in the event of an emergency is challenging, especially in elderly HF patients, because of the difficulty in accurately predicting the prognosis of the condition. Furthermore, advanced HF patients are often fitted with a device, and device deactivation at the end of life is a complicated process. Treatment strategies should thus be discussed by multi-disciplinary teams, including palliative experts, and should consider patient directives to address the problems discussed above. Open communication with the HF patient regarding the expected prognosis, course, and treatment options will serve to support the patient and aid in future planning.
