This study aimed to investigate and compare the perception of personal protective equipments and instrument sterilization of students who are in attendance at colleges and universities and which have bedside training as a regular subject in their curriculum for third-year students. 'Completely True' is the highest response to the question about the importance of wearing gloves, mask and medical gown from all groups. 'Completely True' is the highest response to the question about the necessity for replacement of gloves from all groups. 'Moderate True' is the highest response to the question about the necessity for replacement of mask from the group without practical training and 'Completely True' is the highest response to the question about the importance of hair cleanliness from all groups regardless of practical training experience. For the question about the perception of instrument disinfection and sterilization, the group with inside and outside practical training showed the highest perception level. Consequently, the right education for prevention of infection by setting inclusive guidelines to enhance the level of perception and practice seems continuously necessary.

The purpose of this study was to investigate the UVA radiation protection effects of summer hats currently on the market with the purpose of making it possible to choose a hat with suitable UVA protection. Twelve different summer hats from the market were selected for the experiment. The results are summarized as follows: It is more effective to wear a hat than not wear a hat to block UVA radiation. Summer hats with the greatest degree of protection, from highest to lowest, are cotton, straw2, and straw1. In the area of the forehead, which is rarely influenced by the irradiation angle, the cotton hat was the most effective in protecting from UVA radiation because the material density was greater than that of the straw hats. A hat with a 8.5 cm brim was more effective at blocking UVA radiation on the jaw than 6 cm, 4 cm, and 0 cm wide brims, but it still couldn't block the radiation completely. Irradiation amounts at 11:00 AM on the forehead, jaw! s and left and right cheeks were lower than amounts measured on the back of the neck. This revealed that irradiation amounts depend on the shape of the hat and time of day. A hat with a brim encircling the head was found to be more effective in blocking UVA radiation than a hat with only a front or side brim.

The digital content was supplied quickly with advancement of video compressive technique and the network. Simultaneously illegal copy and diffuse via Internet, it was caused to necessitate the intellectual property right protection of the digital content. With this background, Various standardization groups and content provision enterprises developed the solution for a digital content protection. But the problem which lack interoperability is appeared, cause of independent development among other equipment. To find solution about this, MPEG(Moving Picture Experts Group) has progressed standardization against IPMP (Intellectual Property Management and Protection) techniques which are possible interoperability. In spite of it, with reason why insufficient function, DMP(Digital Media Project) standard was presented with the alternative against this. In this paper, we analyze MPEG IPMP standards and DMP ToolPack concepts to compare between them, and through these, designed and implemented digital content protection system which possible interoperability.

Transmission congestion is one of the key factors to local market power in competitive electricity markets. Financial transmission rights provide the financial protection to their holders by paying back the congestion cost. However, the market participants who have market power can exacerbate their market power. Due to the exacerbated market power, this paper analyzes the mitigation of local market power using Contingent transmission rights on the market price. Contingent transmission rights provide not only the financial protection but also regulative penalty. The proposed methodology was demonstrated with the Optimal Power Flow(OPF).

The intellectual properties right are becoming very critical issues in domestic fashion industries and also international trade. Although it is true that intellectual properties rights are commonly infringed in fashion industry, none of researches has been done for this matter. The present study is to analyze the patterns of infringement by case analysis, which was limited to trademark and trade dress. As a result, in case of trademarks, counterfeiting was relatively clear case, but it is generally investigated by prosecutes whereas the judgement of similar trademark has been taken by legal lawsuit. In case of industrial design(trade dress) most of disputes were related to textile design and modified Korean tradition dress. Reflecting the short history of protection of intellectual properties rights many informations and legal regulations should be established by te government and by the association of fashion related industry.

The purpose of this study is to suggest the revision direction of the Korean Child Welfare Law based on the results of the comparative analysis on the Korean Child Welfare Law and the Japanese Child Welfare Law. The main results are: Both laws have only two provisions about children's participation right. The child protective system in Japan secures the swiftness of within-two-months period of temporary protection through the child consulting center, the investigation right by the child welfare worker, publicity, enforcement on the parents' rights, and the network with the nearest child supporting center. Furthermore, those provisions with the notifying obligation by a finder of the child who needs protection and the limit of protection period are guaranteed in order to ensure the effectiveness of law enforcement. However, Korean child protective system functions only as pre-substitutive service. While the provisions for the disability children account for 21.2% of the total Japanese law, there is no provision on that in the Korean law. The Japanese law is substantially different from the Korean law in a sense that it obligates the minimum quality criteria of child service and national financial burden on the child welfare. While the Japanese law clearly stipulates the national responsibility in relation to the degree of the rights, the Korean law does not directly touch upon it. Furthermore, the Japan's law guarantees that not only children but also protectors retain the right to choose and apply for services.

The web-based technology allows anybody who has access to the Internet to get all kinds of information from the World Wide Web. It brings about issues regarding intellectual property and copyright threats. After content is downloaded, no further protection is provided on the content that has been accessed. DRM (Digital Right Management) technologies came out to ensure the protection of copyrighted content and information. In this paper, we propose architecture of license-based digital rights management system for protection of contents and principles' rights such as contents creators, providers, distributors, and uses in contents distribution value-chain over Internet. This system makes on-line processing of all value-chain from creator to purchaser possible, compared with existing DRM products only supporting only limited distribution between distributor and purchaser.

This study derived measures to reduce exposure doses by identifying factors which affect the external radiation dose rate of patients treated with radiopharmaceuticals for PET-CT tests. The external radiation dose rates were measured on three parts of head, thorax and abdomen at a distance of 50cm from the surface of 60 PET-CT patients. It showed there are changes in factors affecting the external radiation dose rate over time after the administration of F-18 FDG. The external radiation dose rate was lower in the patients with more water intake than those with less water intake before the injection of radiopharmaceuticals at all three points: right after the injection of radiopharmaceuticals (average 4.17 mins), after the pre-PEET-CT urination step (average 77.47 mins), and right after the PET-CT test (average 114.15 mins). The study also found there is a need to increase the amount of water intake before the injection of radiopharmaceuticals in order to maintain a low external radiation dose rate in patients. This strategy is only possible under the assumption that the quality of the video has not changed after conducting this study on the relations between the image and quality. This study also found a need to use radiopharmaceuticals with the minimum amount needed for each patient because F-FDG doses affects the external radiation dose rate at the point right after the injection of radiopharmaceuticals. Urination frequency was the most significant factor to affect the external radiation dose rates at the point right after the PET-CT test and the point after the pre-PET-CT urination step. There is a need to realize the strategy to increase the urination frequency of patients to maintain the external radiation dose rate low (average 77.47 mins) before and after the injection of radiopharmaceuticals. In addition, at this point, there is a need to take advantage of personal strategies because the external radiation dose rate is lower if the fasting time is shorter, the contrast medium is used, and the amount of water intake is increased after the administration of radiopharmaceuticals. Finally this study found the need to be able to generalize these findings through an in-depth research on the factors affecting the external radiation dose rate, which includes radiopharmaceutical dose, urination frequency, the amount of water intake, fasting time and the use of contrast medium.
