This paper intends to prove that the props in movies can be used to communicate messages ans themes to the audience very usefully. I selected the movie "her" to investigate by the use of props. The props in the film can communicate with the audiences without a dialogue and visual. At the same time, the props can make a audiences sympathy as a role playing like a main character. As a result, the props used in the movie were explained to study their relevancy to the narratives of the movie. The props in the movie is so useful and powerful, and then image is more important than any other things in the movie as a narrative tool and storytelling.

The purpose of this study is to suggest for future public libraries in the knowledge information society. The development of Internet requires to change the role of information service in public libraries, and the change of social circumstance requires the role of public libraries as cultural spaces. For the future public libraries, the suggestions are that public libraries provide an instruction for users in order to got information through Internet. Next, public libraries provide comfortable safe, luxury space in order to create regional culture so that users can get experience high culture, and use the space as cultural living zone.

The shipboard working environment of coastal ship is very inferior too the ground working environment and it causes the avoidance of shipboard working and the aging of crew. Especially the air pollution and electromagnetic wave in ships causes an occupational disease. hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in this paper, first we evaluate the shipboard working environment by using the measurement results of the shipboard air polluting and electromagnetic wave in the sea. And we propose the reduction measures of shipboard working fatigue based on the evaluation results of the shipboard working environment.

The shipboard working environment of coastal ship s very inferior to the ground working environment and it causes the avoidance of shipboard working and the aging of crew. Especially the noise in ships causes an occupational disease such as hardness of hearing. Hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in the sea. And we propose the shipboard working environment by using the measurement results of the shipboard noise and vibration in the sea. And we propose the reduction measures of shipboard working fatigue based on the evaluation results of the shipboard working environment.

The human being continued the processing of improvement for well being life according to scientific results The other hand, All the seaman life take the rest and sleep in ship's office and living room. In this case, many crew took the pain of back spain or deposit the his fatigue, This will be decrease the productivity owing to crew's back spain or fatigue etc. In this study researched the problem of ship's bed mattress and the principle of Well being air mattress in technical standard etc. Specially decreased some kinds of bacillus, germ and many kinds of bacteria by using of tourmaline which emitted the far red light and negative ion from surface of the mattress. We developed and applied the ship's Well being air mattress to off shore and various kind of ship by International Labour Organization convention 192.

Recently, it is increased to apply the inverter system to household electrical appliances, especially in the air c conditioners, refrigerators and washing machines, to reduce the power consumption and the acoustic noise by t the low speed operation, and to make their functions more comfortable for human beings. For the inverter s systems, however, it is highly required to reduce the undesirable electromagnetic noise and psychoacoustic n noise generated by PWM for variable speed operation. In this paper, the electromagnetic noise for the d detenninistic PWM and random PWM for the reciprocating compressors driven by the brusWess dc motor was a analyzed. It was also verified through the experiment that the elt'Ct$\tau$omagnetic noise was reduced and the s sound quality was improved by applying the random PWM.

This Paper addresses what amount of whole-body vibration is exposed to Korean pilots of UH60 helicopters during their mission flight. To measure the expose4 whole-body vibration, the 12-axis whole-body vibration measurement system was used. It enables the direct measurement of whole-body vibration exposed from the body contact area consisting of the feet, hip and back. The measured 12-axis vibration signals were used to evaluate the vibration comfort level experienced by the pilots of UH60 helicopters. The evaluated vibration comfort level is found to be closeto 0.74-0.79m/s, which is equivalent to the semantic scale of 'fairly uncomfortable'. To assess the health effects of whole-body vibration exposed to Korean pilots of UH60 helicopters during their mission flight, the rms-based and VDV(vibration dose value)-based evaluation schemes, recommended by ISO 2631-1:1977, were exploited in this work. The evaluated results indicate that Korean pilots cannot avoid the fatigue-decreased proficiency limit after two-hour continuous flight. The whole-body vibration level exposed from the UH60 helicopters during continuous 10-hours mission flight is found to reach to the vibration exposure limit.

This study investigates the criteria for assessing the vibration serviceability of highway bridges using advanced driving simulator. Reiher-Meister Curves were firstly reviewed for extended application to serviceability of highway bridges. Modified Reiher-Meister Curves were provided in this paper based on field test results and numerical analyses results. The Modified Reiher-Meister Curves were evaluated using advanced driving simulator. The new curve consisted of 4 level, A(Disturbing), B(Strongly perceptible), C(Allowable), and D(Comfortable). The new criteria will be extensively applied to design and maintain highway bridges with respect to driver condition.

The reduction of the airborne noise level is essential to the comfortability for mien and passengers in ships. In this paper, the acoustic characteristics on the multilayered acoustic panel with the Helmholtz resonator was described analytically and experimentally. The design software based on the Transfer Matrix Analysis(TMA) method for the acoustic enclosing panel was developed. According to the change of the design parameters of the panel, verious transmission losses were obtained using the developed software. As a result, it was verified that the acoustic characteristics of the composite panel was excellent in comparison with the conventional acoustic partitioning structures. This panel can be applicable to the acoustic enclosure system.

Two naturalized plants (Euphorbiaceae) were recorded from Busan Metropolitan City and from the Jeju Special Self-Governing Province. Euphorbia heterophylla L. (A-me-ri-ka-dae-geuk) was found in a park near Suyeong-gang, Allak-dong, Dongnae-gu, in Busan Metropolitan City. This species is distinguished from E. dentata by its alternating leaves of main stem and glands of involucres with a circular opening. Euphorbia hirta L. (Teol-ttang-bin-dae) was found in Yerae village, Yerae-dong, Seogwipo-si, in Jeju Special Self-Governing Province. It is distinguished from E. hypericifolia as it has capsules with hairs.
