Plain old Web Services came true a services integration with use the XML that will be able to define a platform-independent document format in basic document format. Hut, the XML document decreases the efficiency of the whole application program with connects frequently in relatively slow communication media like network environment, embedded system or use the resource limited small-sized instrument like mobile. In this paper, we implemented the algorism of Fast Infoset, which can convert XML into Fast XML using the Fast Inoset method and PER encoding rules in ASN.1 and constructs Test Bed. Also, it is compared with the existing pure XML message method in difference of process performance after encoding SOAP messages of XML basis when constructing web service.

In the advent of the twenty-first century, human beings began to closely interact with technology. Today, technology is developing, and as a result, the world wide web (www) has a very important place on the Internet and the significant task is fulfilled by Web services. A lot of Web services are available on the Internet and, therefore, it is difficult to find matching Web services among the available Web services. The recommendation systems can help in fixing this problem. In this paper, our observation was based on the recommended method such as the collaborative filtering (CF) technique which faces some failure from the data sparsity and the cold-start problems. To overcome these problems, we first applied an ontology-based clustering and then the k-nearest neighbor (KNN) algorithm for each separate cluster group that effectively increased the data density using the past user interests. Then, user ratings were predicted based on the model-based approach, such as singular value decomposition (SVD) and the predictions used for the recommendation. The evaluation results showed that our proposed approach has a less prediction error rate with high accuracy after analyzing the existing recommendation methods.

This study was conducted to determine the effect of rice bran on rice yield, grain quality and weeds control depending on applying times. The redox potential was severely reduced $4{\sim}7$ days after rice bran application but that of conventional practice was reduced 17 days after transplanting. During the decomposing of the rice bran in the water, the dissolved oxygen in the water was exhausted right away after rice bran application. The dry weight of weed increased as the rice bran application time was delayed that weed dry weights increased by 138% in applying before puddling (ABP), 219% in 5 DAT (days after transplanting), 300% in 7 DAT and 619% in 9 DAT compared to conventional practice. The rice yield reduced remarkably in rice bran treatments after transplanting compared to conventional practice and applying before puddling. In the rice quality, the head rice ratio in the rice bran treatment was higher than that in conventional practice, and its protein content decreased. The results confirm that the rice bran application make the rice palatability higher, but there was no difference in rice qualities depending on application times.

Objectives: As the number of people with disabilities is increasing and their needs for care are varied, the continuum and comprehensiveness of their rehabilitative care are getting more important. This study was performed to understand the utilization of rehabilitation services and requirements of care among the people with severe disabilities in Korea. Methods: We interviewed 578 disabled persons who had severe extremity and cerebral impairment in the urban and rural areas of Korea. The questionnaire included questions on their general characteristics, the type of disability, their physical function (ADL, IADL), their use of rehabilitation services after discharge and their requirements for rehabilitation care Results: Only 12.6% of people with disability in the community continuously used the available medical rehabilitation care. The associated factors for utilization of rehabilitation services were pain and admission for rehabilitative treatment in the acute phase. There was a great need for rehabilitation services in community and this varied according to gender, the socio-economic status, the functional status and the geographic region. The gap between utilization and need for rehabilitation services was largest in the economic support. The gap of primary health care was larger in the rural area than in the urban area. Conclusions: The needs for rehabilitation service were diverse according to the individual functional status, the regional characteristics and other general characteristics of people with disability. Strategies should be considered to eliminate the barriers to obtain rehabilitation services for the people with disability in the community.

In this paper, we review and classify shopping information services for electronic commerce in Korea. Shopping information services for electronic commerce can be divided into shopping mall information service and product information service. Shopping mall information service simply shows and suggests information on the shopping malls that it has in its data store. But product information service provides information about the items of the shopping malls the service has and therefore gives more powerful and convenient interfaces to users. Cutting-edge product information services can perform online comparison shopping facility, which searches and compares the items what the users want on the reasonable basis of economical criteria, such as price. Books, CDs, and Personal Data Assistant(PDA)s are the products of which the specification is clear enough to be described on the Web. And the comparison of the products by the information service is performed on the basis of "price" of the product item. The approach to design and implement product information service can be divided into two categories. The one is an application of data warehousing mechanism, which stores the product information on the regular basis of time and provide it when the users query over the Web-database gateway. The other approach is a shopping agent mechanism, which stores information on "how to shop" and the shopping agent collects the information of product items just after users query about the product and provide the information in real time or notify them by alerting service. Thirty nine shopping information services are compared and classified in this paper and they are extracted from "Naver" and "Yahoo! Korea". The final result shows that most services are just a simple shopping mall information service in growing stage, product information services with data warehousing are lack in product ontology in middle stage, and that product information services with shopping agent are in early stage.

This study investigated the quality characteristics and volatile flavor components of aronia wine (Aronia melanocarpa (0~100%)). After 12 days of fermentation, the alcohol contents of aronia wines ranged between 9.0~12.0%. The pH level and total acidity of aronia wines were 3.20~3.68 and 0.57~0.76 g/100 mL, respectively. The organic acid analysis of wine containing 100% aronia, revealed malic acid content at 3.70 mg/mL, followed by tartaric acid, lactic acid, and citric acid. As the aronia content increased, both the total polyphenol content and the antioxidant activity (the DPPH radical scavenging activity) also significantly increased. The total polyphenol content was the highest in the wine with 100% aronia (461.33 mg%), and the antioxidant activity showed the highest values in the wine with 100% aronia (91.91%). Volatile flavor component analysis of aronia wines identified 8 alcohols, 12 esters, 4 ketones, and 7 other compounds. In the sensory evaluation, the color, flavor, and taste of wine with 20% aronia showed higher values than other aronia wines. Based on the results of the present study, we suggest that 20% aronia is most beneficial in improving the quality as well as sensory characteristics of the wine.

This study was performed to analyze the improvement of soil physical property and soil biota characteristics through cultivation of green manure crops for a one-year period before creation of a tea plantation as follows. The study revealed that the contents of available phosphate tended to decrease after sod-culture by green manure cultivation and open-pollination, when compared to the level before cultivation. The ratio soil porosity increased by approximately 30% when Crotalaria juncea and Sorghum bicolar L. Moench were cultivated, while the soil bacteria and fungi also increased. In a research on microfauna using a pit fall trap, the population number of the microfauna was 174 of 27 species in the plot of open-pollinated sod-culture and no organic matter application, and 268 of 26 species in the plot of Sorghum bicolar L. Moench. Consequently, the culturing tool of Crotalaria juncea recorded the highest level of species diversity at 2.5, the evenness index at 3.7 and richness at 4.6, with the lowest level of a dominance index. The ecological quotient of microfauna was 0.76 in the plot of Sorghum bicolar L. Moench, and 0.63 in the plot of Crotalaria juncea.

The review of known decisions showed that currently there are no systems and technologies for supporting the decision about the possibility of concluding the civil law agreements for medical, therapeutic and dental services. The paper models the decision-making support process on the possibility of concluding the civil law agreements for medical, therapeutic and dental services, which is the theoretical basis for the development of rules, methods and system for supporting the decision about the possibility of concluding the civil law agreements for medical, therapeutic and dental services. The paper also developed the system for supporting the decision about the possibility of concluding the civil law agreements for medical, therapeutic and dental services, which automatically and free determines the possibility or impossibility of concluding the corresponding civil law agreement for the provision of a corresponding medical service. In the case of formation of a conclusion about the possibility of concluding the agreement, further conclusion and signing of the corresponding agreement takes place. In the case of forming a conclusion about the impossibility of concluding the agreement, a request is made for finalizing the relevant agreement for the provision of the relevant medical service, indicating the reasons for the impossibility of concluding the agreement - missing essential conditions in the agreement. After finalization, the agreement can be analyzed again by the developed system for supporting the decision.
