Plagiarism concerns in the melody of popular music are on the rise. Despite these concerns, standards and methods for addressing these issues are lacking. This study is significant in the fact that it is the first case in the media which started as a controversy on plagiarism of popular music and even progressed to Supreme Court ruling. The first and second trial courts declared the existence of infringement of copyright by recognizing that the music in question was substantially alike as a result of comparing and reviewing the melody, rhythm, and harmony. However, the Supreme Court came to a different verdict on the infringement of musical work by reversing and remanding the case to the Seoul High Court. The Supreme Court indicated that even though the music presented in the first trial is a creative work entirely protected under the Copyright Act, expression without creativity is an area that is not protected under the law. Based on this case, this study seeks to compare and analyze the essential characteristics of melody in the judgment of infringement of copyrights in popular music, and factors related to the judgment of practical similarity and the judgment of idioms that are the criteria for judging infringement of musical work.

The purpose of this study is to evaluate the structural risk and weakness of a railway tank car through nonlinear collision analysis according to overseas collision safety standards. The goal is to propose a crash safety design guideline for railway tank cars for transporting dangerous goods in Korea. We analyzed the buffer impact test procedure of railway freight cars prescribed in EN 12663-2 and the tank puncture test criteria prescribed in 49CFR179. A nonlinear finite element model according to each standard was modeled using LS-DYNA, a commercial finite element analysis solver. As a result of the buffing impact test simulation, it was predicted that plastic deformation would not occur at a collision speed of 6 km/h or less. However, plastic deformation was detected at the rear of the center sill and at the tank center supporting the structure at a collision speed of 8 km/h or more. As a result of a head-on test simulation of tank puncture, the outer tank shell was destroyed at the corner of the tank head when 4% of the kinetic energy of the impacter was absorbed. The tank shell was destroyed in the area of contact with the impacter in the test mode analysis of tank shell puncture when the kinetic energy of the moving vehicle was reduced by 30%. Therefore, the simulation results of the puncture test show that fracture at the tank shell and leakage of the internal material is expected. Consequently, protection and structural design reinforcement are required on railway tank cars in Korea.

Most of the important visual information is presented to driver through the display panel that is related to the vehicle. If display panel is designed with the c consideration of driver's visibility, drivers can get broad visual field and visual I information related to vehicle promptly and exactly during driving situation. Therefore display panel has direct relationship with the driver's task performance and it can be considered as an important device that affects the driver-automotive interaction. Many r researches about shape, characteristic and color of display panel have been performed, but not sufficient in this country Nowadays most of vehicles has an analog type display. but its shape and arrangement a are various without any definite standards about position. Therefore. experiments using evaluation tool (VISVEC System) were conducted to inquire the driver's preference on the major objects arrangement of display panel (speedometer. tachometer. fuel meter. and t thermometer) and to ascertain the factors that have an effect on drivers according to the objects position of the display panel The experiment results showed that there was no correlation between the arrangement c characteristics preferred by subjects and the cognitive accuracy but the cognition of V visual information more easy when the each major object has its area.

The purpose of this study is to suggest the minimum distance needed between landscape trees and apartment buildings. in order for the trees to grow soundly and maintain constant growth. Therefore, this study investigated and analyzed the present conditions of the green-spaces contiguous to apartment buildings and the trees inside the apartment complex. The following general problems were identified : (1) the tree growth conditions, (2) the planting intervals, and (3) the planting methods in the apartment complexes. The method of this study was to survey areas, measure the trees and analyze the results. Ten apartment complexes located in Seoul were randomly selected for this study. To analyze the greens contiguous to the building of each apartment complex, the greens were divided into three types, including the front greens, the side greens, and the rear greens. The study surveyed the width of all contiguous greens and the distance from trees to my given building. Four representative sites were specifically investigated to measure the crown widths, heights, and diameters of the trees. These investigations were carried out over 3 months from August to December 2006. According to the results of the study, it was found that the greens are narrower in width and the more closer to a building. The study identified a correlation between the tree and the passage of time after the completion of construction of an apartment complex, showing that the malformation of the trees worsened as time passed. As a result of measuring the right crown and left crown width with the tree trunk as the center, a broad difference was found between coniform trees and trees that tend to branch out more. For example, the ratio of the width of the Acer palmatum is 1:6. However, the ratio of the Metasequoia glyptostroboide is 1:1.7. Based on the overall analysis, it was concluded that the maintained minimum width must be greater than one meter over the green space according to the 'Landscape Standard 2000'. However, that is only applicable to cases such as apartment buildings that present no obstacles. In conclusion having greens placed within one meter of width to a building is not an appropriate environment for the healthy growth of trees. To create sound green spaces, sustainable, long-term growth rate and size should be considered. It is necessary to prepare new standards for the computation of planting trees and the measurement of square landscapes. Wall greenery and shrubberies could be an alternative in the case of a narrow-width green space.

Di-(2-ethylhexyl)phthalate (DEHP) may be released from plasticized poly(vinyl chloride) (PVC) articles. In the cases of various methods for the quantitative analysis of migrating DEHP, there are much differences in migrating quantity according to the experimental methods. It is therefore important to make the comparison and analysis between these two results. A study of DEHP migration from blood and infusion bags has been carried out in different methods to evaluate the amount of DEHP migration using gas chromatograph and UV-vis spectrophotometry. Five PVC bags were cut into plane sheets in size of $40{\times}10{\times}0.4mm$, then were immersed in extraction solvent for an hour to release DEHP. It was determined by a gas chromatograph that $23.2{\sim}70.9{\mu}g/mL$ of DEHP was extracted. While extraction solvent was injected into PVC bags which were then placed for an hour to leach DEHP out. It was checked by a UV-vis spectrophotometer that the concentration of DEHP in extraction solvent was $24.8{\sim}41.3{\mu}g/mL$. Two results show different values according to the extraction conditions and experimental methods and the gas chromatographic results were converted into UV-vis spectroscopic results on condition that DEHP would be extracted equally per unit time and unit contact area. It was concluded that DEHP migrating amounts are approximately equal in two analytical methods.

Tactile acuity was assessed in groups of control, blind, deaf, and blind caused by complication to investigate the effective tactile stimuli on tactile sensory substitution studies when tactile display is applied to persons with sensory loss of vision or hearing. Two-point discrimination and grating resolution were assessed by compass and JVP dome, respectively, in the hand, arm, neck, lumbar, and knee. In two-point discrimination by compass, control group showed the highest sensitivity in fingers among assessed body areas but did not show any significant difference between male and female. Blind group and deaf group compared to control group did not show any significant difference in fingers but showed lower sensitivity in arm and knee. In grating resolution by JVP dome, control group did not show any significant difference among five fingers as well as between male and female. Blind group showed higher sensitivity in five fingers compared to control group, but deaf group did not show any significant difference from control group. Blind caused by complication group showed lower sensitivity in two-point discrimination and grating resolution compared to control group and blind group. These results suggest that the body area and method of tactile stimulation, and difference in tactile acuity depending on underlying disease of sensory loss should be considered when tactile display is applied for sensory substitution.

Persistent accidents related to food safety and expanded international trades have urged the world to be aware of the gravity of the accidents. Accordingly many countries have tried to come up with various laws, regulations, measures, support networks and educational programs for the agenda, particularly focusing on harmonizing food safety technologies among nations and fostering professionals. Also, APEC newly organized Food Safety Cooperation Forum (FSCF) in 2007 to exert multi-dimensional efforts to improve food safety for Asia Pacific nations. Up to now, 35 activities have been promoted since 2007 and additional 20 activities are waiting for their turns for action on the list of APEC project agenda. FSCF has the objective that it helps the stakeholders in food supply chain develop their own competence in that area, thus increase international trade among nations and maintain the globe healthy by applying the highest standards and best practices for the management of food safety ranging from production to consumption. To achieve this strategic objective, APEC subsequently formed Partnership Training Institute Network (PTIN) to build up the multilateral networks of specialists from governmental agencies engaging in food safety management, industries, academia and international organizations in Asia-Pacific region. This attempt made it possible for the world to exchange their scientific and technological information concerning food safety and strengthen related education and training. Today, international cooperation is essential for food safety management. Therefore, we need to participate actively in the activities of APEC FSCF to contribute to improving food safety technologies for the member countries of APEC. We also need to connect the domestic support programs with theirs.

At this, in this study, some tests were conducted to come up with a method to minimize intervention, to reduce the secondary damage to original materials, and to produce remarkable reinforcing effects. The followings show objective standards. The proportion of original material to steel reinforcement bar (the ratio of steel reinforcement bar) needs to be calculated in light of weathering intensity. Second, in the case of partial damage, prosthetic treatment is applied to add new stone materials to original materials. In that case, the ratio of steel reinforcement bar should be calculated based on material that is highly resistant to weathering. With the results of this study, it is possible to suggest conditions that can structurally stabilize stone cultural heritage, according to the weathering area. As a result, the ratio of steel reinforcement bars can be 0.13 to 0.23 in the case of $800kgf/cm^2$ or less, 0.24 to 0.28 in $800kgf/cm^2$ or higher, and 0.29 to 0.5 in $1200kgf/cm^2$ or higher. In particular, there is the need to take the coefficient of rupture of stone material and the properties of the steel reinforcement bar into account in cases of calculating the ratio of steel reinforcement bars according to weathering intensity.

In this study, the systems and standards for temporary equipment and materials established in domestic and foreign countries are examined to provide improvement schemes and to insure their safety. Statistical analyses of the data obtained from the internet and/or field visit surveys of employees working in manufacturing, leasing, and construction companies related to temporary equipment and materials and improvement schemes were conducted to evaluate the implementation of a safety certification system for currently used temporary equipment and materials. This safety certification system has been enforced since 2009, but the number of accidents at construction sites, which are reported by the 'serious accident cases and measures in construction sites' group of the Korea Occupational Safety & Health Agency (KOSHA), has increased. The respondents' answers regarding the suitability of the items, which are required for the safety certification of the equipment and materials, were 'yes (36%)', 'no (30%)', and 'unknown (35%)'. Less than half of the answers regarding the current system were positive and most of the respondents answered that the current system does not reflect the evolution of the construction environment. A system is needed to approve items certified in foreign countries and newly developed materials and items, in addition to the (automatic) registration for the reuse of temporary equipment and materials, and improvements are needed in their safety. In this study, after examining the size and practicability of the items requiring approval from the current system, the certification methods are reevaluated and improvement schemes are provided for the system.

This research prepared safety standard for out-door fitness and this research's purpose is to evaluate and investigate safety condition for out-door fitness which was distributed in domestic residence by applying TUV standard which evaluate product's safety inspection. We choose twelve companies which have many sales' amount and investigated for ten out-door fitness which have high consumer preferences. As a result of that, the ratio of successful applicants for safety evaluation was 55.1%. The terms desired was evaluated highly in safety for out-door fitness's fixing condition. However, the terms desired was evaluated lowly in safety for movable condition. Fitness equipment which has high consumer preferences was compared lowly than other equipment in safety part. It was analyzed that there was no difference in safety evaluation according to manufacturing company. So, it is necessary to prepare safety standard by establishing law in order to prevent accident while they are using because we cannot think that fitness equipments which was distributed in domestic area have high safety. We think that preparing safety standard can influence on preventing accident and reinforcing out-door fitness manufacturing companies' competitive.
