To query the vast amount of web pages which are available in the Internet, it is necessary to extract the encoded information in the web pages for converting it into structured data (e.g. relational data for SQL) or semistructured data (e.g. XML data for XQuery). In this paper, we propose a new web information extraction system, PIES, to convert web information into XML documents. PIES is based on a user-specified schema and HTML tag pattern descriptions. The web information is extracted by the pattern descriptions and validated by the schema. We designed a new language to describe extraction rules, and a new regular expression language to describe HTML tag patterns. We implemented PIES and applied it to the US patent web site to demonstrate its feasibility. It successfully extracted more than thousands of US patent data and converted them into XML documents.

The aim of this article is to improve human health and that of companion animals by improving the diagnosis and control of parasitic diseases. This is achieved by research into parasites of veterinary significance including zoonoses and the use of comparative systems to increase our understanding of some human parasitic diseases. We should promotes learning and teaching through knowledge and operates a diagnostic unit that offers a service to pet owner for indigenous and exotic parasitic diseases of companion animals. We must diagnose and treat them early. Zoonotic parasites are very important because many of animal parasites are zoonoses and give pain and death to human. Parasites are divided Protozoa, Helminthes and Arthropods. There are many protozoa, about 65,000 species. Arthropods are the vector of another diseases, such as virus, bacteria, protozoa and nematodes. Helminthes are composed of Trematoda, Cestoda, Nematoda and Acanthocephala. The target of Veterinary Parasitology is to recognize the characteristics of these parasites and subsequently diagnose, treat and control them. This article is intended to familiarize you with the essential facts and concepts of companion animal parasitology. Emphasis is placed on fecal sample techniques (comparison of fecal examination techniques; frequently found artifacts in fecal smears; direct Smear; zinc sulfate flotation; etc.) We recommend that the study be done to more references on animal parasites.

국방전산망의 인터넷 연결을 위한 망구성 방법과 정보보호 정책

The existing National Defense Network (NDN) is a closed one that allows no access from outside for information protection. The purpose of this paper is first to propose a solution for opening NDN to Internet to enhance its flexibility, and second to propose the several policies for protecting critical military information from outside, For the first purpose, we suggest that NDN be divided into many elementary networks connected to each other by way of VPN. An elementary network consists of a gateway, a firewal, an IPS (Intrusion Prevention System), a dummy network, and many user computers. In addition, we suggest that there should be a central certification center for certifying data and identifying users. For the second purpose, we suggest some policies about separating service network from other parts of NDN and different data protection categories: ordinary, certified, and encrypted. Tn addition, we suggest that two special teams be organized responsible for information protection and new technology application respectively. To our knowledge, this paper first tried to connect NDN to Internet, and proposed a solution to solve the security problem. We believe that this paper can contribute to the national defense policy for interconnecting NDN with Internet.

The present study was carried out to investigate the potential acute toxicity of safflower seed by a single oral dose in ICR mice. Twenty animals of each sex were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, and 2,500 mg/kg bodyweight. Mortalities, clinical findings, and body weight changes were found and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects in clinical signs, body weight, and gross findings at any dose tested. The results showed that the single oral administration of safflower seed did not cause any toxic effect at the dose levels of 2,500 mg/kg in rats and the minimal lethal dose was considered to be over 2,500 mg/kg body weight for both sexes.

Database Auditing examines whether the database has been developed suitably for the purpose of business, and presents problems and recommendations to support the successful construction of database. The examination also ensures the integrity, the availability, the confidentiality of the database constructed. Since Database Auditing is strongly related with many other fields, each auditing company has its own auditing method. In other words, all the auditing companies adopt their own independent auditing system. As a result, there cannot be presented a consistent recommendation for the same problem. In this thesis, we propose an automation method of Database Auditing for obtaining consistency in auditing, and present a case study to show the automation scope of Data Auditing. In particular, we present a specific automation method for the following examination points: coherency of data items, logic/physical database consistency, database performance. As a future research, we will establish data quality requirements, complete the guideline of Database Auditing, and develop the tools necessary for the automation of Database Auditing.

김태영,박병권 東亞大學校 經營大學 2004 經營硏究 Vol.- No.17

회계서비스시스템은 세무업무 위탁인과 세무업무 대리인에게 다양한 회계서비스를 제공하는 시스템으로서, 현재 사용되고 있는 회계서비스시스템을 살펴보면 폐쇄형 구조로 인하여 타 시스템과의 통합이나 정보 공유가 불가능하고 단순 회계 정보입력 및 출력만을 위해 사용된다. 따라서, 회계세무정보의 활용도가 현저히 떨어진다. 뿐만 아니라, 세무 위탁인은 세무 대리인에게 기초회계 자료를 전달하기 위하여 데이터를 출력하여야 하고, 대리인은 이를 다시 회계서비스시스템에 입력하여야 하므로 업무가 이중으로 발생하며, 부정확한 입력을 방지할 수 있는 검증 수단이 없다. 본 논문에서는 이러한 문제점을 해결하기 위하여 웹 서비스 기술을 적용한 신(新) 회계서비스시스템을 제안한다. 신(新) 회계서비스시스템을 이용하면 세무업무 위탁인이나 세무업무대리인에게 여러 가지 이점을 제공할 수 있다. 웹 서비스가 가지는 특징인 유연성을 이용하여 기존에 존재하는 시스템들을 통합할 수 있음으로써 위탁인이 정확한 회계기초 자료를 입력할 수 있다. 대리인은 이를 기초로 하여 위탁자에게 실시간 상담이나 내부 회계정보를 분석한 고급 정보를 제공할 수 있다. An accounting service system provides various accounting services to both an accounting agent and his customer. All the existing accounting service systems are closed systems so that they cannot be integrated with other systems for the purpose of information sharing. They are used only for input and output of simple account data to low utilization of accounting and tax information. The customer gathers raw account data to hand in to the agent, who inputs the data to an accounting service system. This may result in a redundant work and cause some input errors. In this paper, we propose a new accounting service system based on the web service to solve these problems. The new system can be easily integrated with other systems and provide various advantages to both the agent and his customer: the input account data is guaranteed to be correct, which enables a valuable accounting information generated and served to the customer.

The present study was carried out to examine the effect of EGF and IGF-I in vitro maturation (IVM) of porcine oocytes and development of porcine IVM/IVF embryos. The results were summarized as follows : 1. The rates of nuclear maturation, penetrated oocytes, pronuclear formation, polyspermic oocytes and mean numbers of the penetrated sperm were not different in NCSU-23 maturation medium with 0, 1. 5 and 10 ng/ml EGF and IGF-I (P>0.05). 2. The rates of blastocyst formation at day 7 after in vitro fertilization in 0, 1, 5 and 10 ng/ml EGF groups were 11.2±1.5%, 15.0±8.3%, 16.8±2.8% and 21.4±2.0%, also 0, 1, 5 and 10 ng/ml IGF- I groups were 11.2±1.5%, 15.0±8.3%. 16.8±2.8% and 21.4±2.0%, respectively. In the total cells case, EGF groups were 22.8±3.7, 25.7±5.5, 26.0±4.2 and 35.1±4.7, also IGF-I groups were 21.5±3.7, 25.2±2.8, 26.2±2.9 and 33.2±3.6, respectively. Both 10 ng/ml EGF group and 10 ng/ml IGF-I group were significantly higher than those of other treatment groups (P<0.05). 3. The rates of blastocyst formation at day 7 in the NCSU23 culture medium of porcine IVF-produced embryos with 0, 1, 5, and 10 ng/ml EGF groups were 14.0±1.7%, 16.2±1.4%, 16.9±1.2% and 23.1±1.6%, also 0, 1, 5, 10 ng/ml IGF-I groups were 13.6±1.7, 15.7±4.5. 16.0±0.2 and 25.0±0.8, respectively. And in the total cells case, EGF grups were 21.8±2.9, 25.2+2.8, 39.7±2.7 and 46.2±3.6, also IGF-I groups were 20.7±2.9, 26.2±2.9, 24.6±2.4 and 46.1±3.5, respectively. Both 10 ng/ml EGF group and 10 ng/ml IGF-I group were significantly higher than those of any other treatment groups (P<0.05). In conclusion, these results suggested that the addition of 10 ng/ml EGF and IGF-I were effective on the blastocyst formation and total cells of blastocysts.
