There are gradually built on electronic commerce and business information system for the effective and automated use of internet while the mainstream of industry moves on information. It is necessary that a company should develop a electronic approval system because the business documents have application to an electronic commerce, business information system as well Currently, electronic approval system on groupware is using the way of inserting the image of an approval signature, which is vulnerable on a security by attacks of fraudulent use of electrical signature and eavesdropping on electronic documents. In this paper, we implementation XML form generator based on DTD having business documents structure for creating a valid business XML documents. we designed electronic approval system based on secured XML which transfers encrypted documents. For the security issues of written XML business documents, it makes use of the crypto algorithm having high performance transaction by the interchange of public key between a server and a client.

Information processing using computer in generalized in the office automation. In spite of to be integrate and concise form of document through computer network, signature of document with hand have processed as ever. The security on document flow out severely unjust by reason of increment inverse function of computer. Because of revelation secret of enterprise result from unjust outflow, lots of loss of self-enterprise is occured. In this paper, we used efficiently document using the method, electronic approval system with encryption, for the resolving above problems. Also we persue maintenance of security for the important document and process document signature rapidly. Finally, we design and implementation of electronic approval system that take one's share of function between server and client using to be transformed Vernam's encryption technique in stored document.

As our society turns into the information age from the industrial one, the ministry of information and communication has set up functional software standards for electronic approval systems Several software houses have developed such systems in the client/server environment and subsequently for the intranet. Although electronic approval systems for the intranet have the advantages of less costly implementation and ease of use, they create heavy network traffic, and have a poor document processing functionality resulting from the lack of document processor in web environments. This paper describes a system design that web browsers utilize the resources of clients by adopting the ActiveX technique in order to improve such mallets mentions above. In other words, to use the Hangul word processor as a document processor, the ActiveX control and the Hangul DDE API have been implemented in the form of the DDE server/client, which is capable of mutual communication, and the flow of electronic approve system has been controled by connecting. As a result of running the implemented system lot three months through a real company in multi-server environment, it shows the high usage of electronic approval system as the tate roaches 75%-93% for some departments.

In the wake of categorizing the design changes occurred during the period from 2004 till the first half of 2006 in Choongcheong province area, based on purpose and reason of design changes identified by the Korea National Housing Corp, it included 11 types such as the image of the apartment complex, scenic elements, consideration by the user, prevention of the defect, constructability, site conditions, incompatibility between the activities, superordinate standard, prevention of civic complaints, design details and others, along with 47 subordinate elements. And the evaluation intended to identify the corelation between the number and time of design change approval, frequency and scale of design change by type and the cost variations indicated that; firstly, enhancing the image of the apartment complex proved to be the main reason for design changes, accounting for 22% in terms of frequency and 54.9% in terms of cost variation. Secondly, the higher the increase in cost by design change aimed at improving the image of the complex, the lower the decrease in cost by design change for uncertain reasons, dubbed the inverse proportional relations, indicating that the design changes for uncertain reasons were mostly aimed at reducing the construction cost. Thirdly, with regard to the number of design change approval and the time of the initial approval, twice or less and 90 days or less before completion of the construction work, respectively, accounted for $52{\sim}53%$, indicating the design change deliberation and approval tended to have been carried out collectively in the form of ex post facto approval, which seemed to be attributable to the attempt of reducing the construction cost or budget problem, as a result of comparing with the cases in which the cost was reduced.

Tablet splitting is used in pharmacy practice to adjust the dose to be administered. However, it also causes several problems such as undesirable effect for sustained release or enteric-coated dosage form, inaccuracy of dose, and pharmacist's safety by splitting hazardous drugs. This study investigated the current status of oral dosage form splitting for patients older than 19 years by analyzing Korea National Health Insurance Claims Database. Out of oral solid drugs prescribed (N=1,486,584) 9.8% of them included tablets (or capsules) split. There were some splitting cases even in sustained release (4.9%), enteric-coated forms (1.3%) and hazardous drugs (2.7%) that were selected by NIOSH (The National Institute for Occupational Safety and Health). The most frequently split drugs were antihistamines, neuropsychotics and steroids. In case of digoxin and warfarin, unit doses in a domestic market were not diverse compared to foreign markets. Guidelines for splitting oral solid dosage forms, approval of diverse doses and conducting dose-response studies for the commonly splitting ingredients on Korean people are needed for the saff and effective use of oral solid drugs.

The fatigue damage caused by wide band loadings has generally been predicted using fatigue damage models in the frequency domain rather than a rain-flow counting method in the time domain because of its computation cost. This study showed that these fatigue damage models can be simplified in the form of normalized fatigue damage as a function of the S-N curve slope and bandwidth parameters. Based on numerical simulations of various wide band spectra, it was found that fatigue damage models in the form of normalized fatigue damage with one S-N curve slope and two bandwidth parameters( α₁ , α₂ ) provided less reasonable fatigue damage. Therefore, an additional bandwidth parameter needs to be considered based on a sensitivity study using various neural networks, which proved that α_1-5 would be the dominant factor of a fatigue damage model as an additional bandwidth parameter.

The purpose of this study was to examine nursing college students' knowledge of and attitudes toward brain death, organ donation and organ transplantation. The research design utilized in this study was a descriptive research design. The data were collected from September 7 to 14, 1998, by means of strutted questionnaire. To measure students' knowledge of brain death, organ donation and organ transplantation, Joo's(1995) instrument was used. The questionnaire was composed of 22 items. To measure students' attitudes toward organ donation and organ transplantation, s(1995) Instrument was used. The questionnaire was composed of 22 items. The data were analyzed by frequency, t-test, ANOVA, and Pearson's Correlation Coefficient using the SAS program. The results were as follows : 1. Students' knowledge of brain death, organ donation and organ transplantation was 9-20. The mean score was 15.36, with 22, the highest possible score. There was statistically significant difference between students' knowledge and approval on the brain death recognition group(t=9.75, p=0.002). 2. Students' altitudes toward organ do nation and organ transplantation showed is mean score of 3.61 on a 5 attitudes points Liken scale. More than 80% of respondents agreed that organ transplantation can offer a high quality of life to the recipient and is an acceptable form of medical treatment. The health care costs associated with organ transplantation are worth itif another's life can be saved. Students felt it important to help others who are very ill. Also, by donating organs, students felt a part of their own body would continue to live by making it possible for someone else to live. Only 2.9% of students objected to organ donation for religious reasons. There was statistically significant difference among students' attitudes, experienced blood donor group(t=17.04, p=0.000), approval on the brain death recognition group (t=21.06, p=0.000), organ donation agreement group(t=46.13, p=0.000).

Purpose: The purpose of this study is to develop guidelines for clinical trial of the total ankle replacement system for premarket approval. Materials and Methods: We selected and analyzed nine peer-reviewed articles whose quality had been proven in a previous phase. Two investigators extracted parameters for guideline criteria, including number of cases, patient age, follow-up period, failure rate, radiographic osteolysis rate, residual pain rate, and percentage of satisfaction. In addition, the inclusion and exclusion criteria were analyzed and developed. Results: Eight level IV studies and one level II study were included. The average number of cases was 159 cases and the mean patient age was 63.5 years. The mean follow-up period was 4.2 years, ranging from two to nine. The average failure rate of total ankle replacement in mid- to long-term follow-up was approximately 13% (2%~32.3%). The rate of osteolysis was approximately 18%. Residual pain was common (21.4%~46%), but overall patient satisfaction was approximately 85.6% (67.5%~97%). Conclusion: The results could be used as criteria for designing the clinical studies, such as number of cases, patient age (over 60 years), and follow-up period (minimum two years). The clinical scoring system and 36-item short form health survey (SF-36) was the most commonly used method for clinical evaluation for total ankle arthroplasty. In addition, the overall results, including failure rate, osteolysis rate, and patient satisfaction, could be used as a parameter of guidelines for premarket approval.
