This study examined the standard how to deal with infringement of copyright legally, by looking at several examples of the infringement of copyright in local video works. When we look at precedents relating to copyrighted motion pictures, there are many times when two works seem quite similar but don't get conformed to the infringement of copyright by deliberating the similarities feebly. Although the Idea seems same, the creative expression is admitted and the substantial similarity is denied. For example, in the case of the soap opera, 'Kareiski', the court presented a standard of judgment by organizing the facts, based on the subjective element, dependence on proof and the objective element, the substantial similarity In the case of 'Fox and the Cotton Candy', the dependence on proof and the substantial similarity were examined as usual but when examining the substantial similarity, it was examined in more specific details. This case is a good reference for solving such a case in the future.

Recently with advent of Web 2.0, RESTful Web Services are becoming increasing trend to emphasize Web as platform. There are already many services and the number of service increases in very fast pace. So it is difficult to find the service what we want by keyword based search. To solve this problem, we developed the search method using sem antic technologies about RESTful Web Services. For that, first we define the system structure and model the description format based on the integrated search system for OpenAPIs, and then we add Semantic Markup (tagging, semantic annotation) on the HTML description pages. Next we extract RDF document from them and store it in service repository. Based on the keywords that are extended by means of ontology, the developed system provides more purified and extended results than similarity-based keyword searching system.

Degumming with enzyme Degummase can be a viable alternative to the existing methods of degumming. Degumming, carried out with the conventional method of Marseille's soap 25%(owf) for 1.5h at boil gives a weight loss of about 24%. On Comparison, degumming with 10 enzyme at 5$0^{\circ}C$ for 60 min gives a weight loss of about 22%. Treatment with enzyme requires a much lower temperature and also the treatment time is shorter than the conventional process. Processing of silk at these conditions is likely to retain the lustre and softness of silk. To economise on the quantity of enzyme, conditions were optimised for a pad-store process. An enzyme concentration of 0.5% at 5$0^{\circ}C$ for a time period of 5~6h resulted in a weight loss of 22%. Though the concentration of the enzyme used was 20 times less than that used for long liquor method there was some strength loss. At 5$0^{\circ}C$ treatments carried out for 7~8 h resulted in some degradation. Strength loss occurs because enzyme in the absence of any stirring keeps acting at the place where it is deposited. Effect of temperature was more pronounced than time in degrading silk.

Generally data loading is a laborous job to develop models. Meteorological data is basic input data for hydrological models, it is provided through websites of Korea Meteorological Administration (KMA). The website of KMA provides daily meteorological observation data with tabular format classified by years, items, stations. It is cumbersome to manipulate tabular format for model inputs such as time series and multi-item or multi-station data. The provider oriented services which broadcast restricted formed information have caused inconvenient processes. Tim O'Reilly introduces "Web 2.0" which focuses on providing a service based on data. The top ranked IT companies such as google, yahoo, daum, and naver provide customer oriented services with Open API (Application Programming Interface). A RESTful web service, typical implementation for Open API, consists URI request and HTTP response which are simple and light weight protocol than SOAP (Simple Object Access Protocol). The aim of this study is to develop a web-based service that helps loading data for human use instead of machine use. In this study, the developed RESTful web service provides Open API for manipulating meteorological data. The proposed Open API can easily access from spreadsheet programs, web browsers, and various programming environments.

The cultural properties of cloth are of animal orgin (silk), or of vegetable orgin(cotton, hemp, ramie). As clothes are of an orginic material, they were subjected to damage by chemical, phisigical or biological factors, viz, moulds insects, lights, humidity and temperature changes, etc. And these factors promote that clothes generally result from various types of deterioration. In 1992, We were performed the conservation treatments for total 9 pieces of cloth, such as 3 pieces of General PAK SHIN-RYONG(Important Folklore Material No.110) 3 pieces of Madam Jung(Important Folklore Material No.115) and 1 piece of King Se-jo(Important Folklore Material No.219). The procedure of the conservation treatment for clothes describe the following below. 1) The washing and dry-cleaning to remove the contaminated substances from cloth was used 0.2% stearyl potassium soap solution and the mixture solution compound of n-Hexane, C6H14. and n-Decane, C10H22. And after the washing and dry-cleaning, the dry of clothes was carried out in a warm condition. These steps were repeated in 2 times over for each cloth. 2) The repair of clothes was attached the similar textiles to stronger fabric linings by needlework.3) The reprodution was made for cloth of King Se-jo to equalize the type, color, quality and skill of materials. 4) After these above procedures, all clothes fumigated to prevent the biodeterioration by using the mixed gas of methyl bromide and ethylene oxide as insecticide and fungicide. 5) Finally for the purpose to keep in a safety long-term condition, the treated clothes sealed with Biaxially Oriented Polyvinylacohol Film(BO-PVA film) and Helium, purity 99.999%, filled up in sealed BO-PVA film bag.

In recent years, a life phenomenon using a workflow management tool in bioinformatics has been actively researched. Workflow management tool is the base which enables researchers to collaborate through the re-use and sharing of service, and a variety of workflow management tools including MyGrid project's Taverna, Kepler and BioWMS have been developed and used as the open source. This workflow management tool can model and automate different services in spatially-distant area in one working space based on the web service technology. Many tools and databases used in the bioinformatics are provided in the web services form and are used in the workflow management tool. In such the situation, the web services development and stable service offering for a sequence similarity search which is basically used in the bioinformatics can be essential in the bioinformatics field. In this paper, the similarity retrieval speed of biology sequence data was improved based on a Linux cluster, and the sequence similarity retrieval could be done for a short time by linking with the workflow management tool through developing it in the web services.

In this study, physically and chemically stable core-crosslinked amphiphilic polymer (CCAP) nanoparticles were prepared using amphiphilic reactive precursors via soap-free emulsion process. Obtained CCAP nanoparticles were used as templates for synthesis of nanostructured $TiO_2$ nanoparticles. First, CCAP nanoparticles dispersed aqueous solutions were mixed with titanium isopropoxide to prepare stable organic-inorganic hybrid sols, and then obtained sols were spin coated onto glass substrate to prepare hybrid thin films onto glass, and then hybrid thin films were calcinated at various temperature to remove CCAP. Nanostructure of calcinated thin fims were examined by SEM. To study effect of CCAP nanoparticles on nanostructure of $TiO_2$ nanoparticles, the morphology of $TiO_2$ nanoparticles prepared using various CCAP templates was compared with that of $TiO_2$ nanoparticles prepared using conventional organic template, nonionic surfactant, Triton X-100.

The principal objective of this study was to evaluate elementary students' awareness of the importance of hand washing, as well as their hand-washing behavior. The data was collected by self-reported questionnaire from 697 students in elementary schools with serving food in a classroom in Busan. Their hand-washing frequency was high, at '3~4 times per day (37.0%)'. 51.0% of the respondents did not wash their hands that often because they were 'not accustomed' to washing their hands, and 35.9% of respondents regarded washing their hands as 'annoying'. The most frequently reported hand washing agent was 'soap and water (71.4%)'. Approximately 95~98% of the respondents always washed their hands after using the bathroom, 87.9% of them washed their hands before eating food, and 86.7% of them washed their hands upon returning home. However, 27.3%, 34.1% and 65.9% of the respondents did not wash their hands after handling money, after eating, and after coughing or sneezing, respectively. Significant factors related to increased hand-washing frequency were gender (p<0.001) and the period of attendance at kindergarten (p<0.05). The mean scores of importance and performance of hand washing were significantly higher for girls than for boys. The group with higher rate (over 4.5/5.0) for the importance of sanitary hand-washing behavior showed significantly higher scores in hand-washing behavior before serving food and before eating than those of the lower rated group (below 4.0/5.0). This study shows that sanitation education is required not only for food handlers but also for students in school foodservices.
