Most of banks in Korea provide smartphone banking services. To use the banking service, public key certificates with private keys, which are stored in personal computers, should be installed in smartphones. Many banks provides intermediate servers that relay certificates to smartphones over the Internet, because the transferring certificates via USB cable is inconvenient. In this paper, we analyze the certificate transfer protocol between personal computer and smartphone, and consider a possible attack based on the results of the analysis. We were successfully able to extract a public key certificate and password-protected private key from encrypted data packets. In addition, we discuss several solutions to transfer public key certificates from personal computers to smartphones safely.

Background: The completeness of cancer registration is a major validity index of any reported cancer incidence. The present study aimed to evaluate the esophageal cancer incidence registered in the Tehran Metropolitan Area Cancer Registry. Materials and methods: The data on esophageal cancer abstracted from three sources of 1) pathology departments, 2) medical records, and 3) death certificates during 2003 till 2007 were utilized. The completeness of the data sources were evaluated using coverage (defined as the proportion of a community population with esophageal cancer identified by the source) and density (defined as the proportion of non-empty fields of the data by source). Results: A total 1,404 cases of esophageal cancer were reported for the duration of the study. Pathology provided 771, medical records 432, and death certificates 609. The coverage was 0.55 for pathology, 0.31 for medical records, and 0.43 for death certificates. The respective density values were 0.82, 0.96 and 0.98, respectively. Pathology (0.45) was the most complete source followed by medical records (0.42), and death certificates (0.29). Discussion: A low degree of completeness dictates putting more effort into case finding plus abstracting data more thoroughly.

The Issuance of false medical certificates on Criminal Law or the Medical Service Act are frequently applied to the insurance fraud cases related with the medical certificate, prescriptions. The meaning of medical certificate is not defined on the crime of Issuance of false medical certificates, but considering the rule of Paragraph 1 of Article 17 of the Medical Service Act, which punishes drawing up the medical certificate by anyone except the doctor who has directly examined, and the principle of legality, the medical certificate applied with the crime of Issuance of false medical certificates should (1) include the judgment after current medical ex-amination, (2) be written for the purpose of verifying the health status and (3) have a style that can be recognizable as medical document usually written by doctors. In addition, since there have been many argues on the range of application of the Paragraph 1 of Article 17 of the Medical Service Act, which generally regulates various kinds of documents such as medical certificates, prescriptions and others, which have different purpose and characters, the range of application of the clause above is needed to be interpreted strictly.

For an efficient role based access control in highly distributed computing environment to reduce management cost, we utilize attribute certificates. Especially highly distributed computing environments such as ubiquitous computing environments which cannot have global or broad control, need another attribute certificate management technique. The techniques for transmission of the attribute certificates and management of the group keys should be considered to reduce management cost. For better performance we structure attribute certificates. We group roles and make the role group relation tree. It results secure and efficient role renewing and distribution. For scalable attribute certificate distribution, multicasting packets are used. We take into account the packet loss and quantifying performance enhancements of structuring attribute certificates.

In this paper, we review digital certificate technologies and their applications in e-commerce. Current digital certificate technologies are evaluated and their importance is explained. The configuration of certificate flows from providers to users through software, hardware, and network technologies is described. These five domains and the configuration of digital certificate flows guide our review of the characteristics of digital certificates. We then develop a framework for the classification of digital certificates that integrate these five domains with VeriSign's types and levels of assurance. In order to demonstrate the adequacy of our digital certificate classification framework, we populated it with VeriSign's digital certificates. Within each domain, VeriSign's classes of digital certificates are classified in accordance with the VeriSign type and level of assurance. The results of our analysis suggest that the framework is a useful step in developing a taxonomy of digital certificate technologies. The strengths and weaknesses of the study are discussed, and opportunities for further research are identified and discussed.

Objectives: The purpose of this study was to examine the food allergy-related knowledge, awareness, and performance of dietitians at children's hospitals, depending on whether or not they have a clinical dietitian certificate. Methods: A questionnaire survey was administered to 41 dieticians at children's hospitals registered as a part of the Korean Hospital Association. The survey consisted of questionnaires examining general characteristics, nutritional counseling-related characteristics, and food allergy-related characteristics (food allergy-related knowledge, awareness, and performance). We examined differences according to the status of clinical dietitian certification. Results: The proportion of subjects who were holders of clinical dietitian certificates was 48.8%. There were differences between holders of clinical dietitian certificates and non-holders as follows. Regarding nutritional awareness and performance, 'needs to provide nutrition counseling in children's hospitals', 'providing nutrition counseling services in working hospitals', and 'whether there is a nutrition counseling room' scored higher among holders of clinical dietitian certificates than non-holders. Holders of clinical dietitian certificates showed higher scores for knowledge of food allergy symptoms and food allergy management than non-holders. For food allergy awareness and performance, 'self-assessment of food allergy knowledge understanding level', 'awareness of open oral food challenge (OFC)', 'recognition of the need for education and counseling on food allergy for patients / guardians', and 'food allergy related educational experience' scored higher among holders of clinical dietitians certificates than in non-holders. Conclusions: Children's hospital dietitians with a clinical dietitian certificate showed high knowledge, awareness, and performance related to food allergies. It is thus necessary to employ a clinical dietitian for food allergy management in children's hospitals. In addition, training and conservative education are necessary for the management of food allergies for children's hospital dietitians.

Currently, different medical institutions have been carrying out the e-healthcare system project. The system includes electronic medical record and prescription delivery system, and, the Medical Treatment law permits electronic signature for medical record management, which reduced the relevant costs and enabled sharing medical record. And medical solution using online certificates is expanding its application. In that light, the role of certificates became more important than ever. However, in contrast to active effort made to manage personal certificates, certificates related to medical solutions and other types of work are not being managed properly. Most work-related certificates are saved in office computers, which makes them vulnerable to various security threats. Although certificate servers can be used as a solution to this problem, hospitals must build the server separately and, therefore, small and medium-size hospitals can be reluctant to bear the burden. This study proposed a way to design and implement an effective and secure certificate management system by save the certificate file as a BLOB, using existing resources without needing to build a separate certificate server, at minimized costs.
