An educational institution issued a degree certificate to those students who have successfully completed all studies included in different levels of the degree program. The degree certificate presented by the University is of major significance in the person's life but the fabrication and circulation of fake certificates is inexpensive because a paper document can easily be forged with the availability of advance printing and copying technologies. So, there is a need to adopt a centralized authentication process that can verify and ensure the authenticity of a document. In order to prevent the spread of fake degree certificates a method is proposed where the integrity of the contents with in the certificate can be verified with the use of and Smart Phone Application. A Quick Response (QR) Code will contain a digital signature over the data such as degree holder's name, major program, Grade Point Average (GPA) obtained etc. Which will be signed by university authorities after the registration in central system and deployed in university. In order to verify the digital signature a person need to use a specific smart phone application which will scan and authenticate the certificate without gaining access to a user's security credentials such as password.

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 purpose of this study was to analyze the levels of food sanitation knowledge and performance by school food service workers. The data were collected by 440 food service workers in Gyeongbuk province. The collected data were analyzed using the SAS package program (version 8.2 for Window). The results of this study are summarized as follows: 28.6% of the respondents worked in food service at the school where their children attended, 93.6% of the food service workers were part-time employees, and 40.4% had obtained cooking certificates. The food sanitation knowledge scores of food service workers differed significantly according to age (p<0.05), holding of cooking certificates (p<0.01), number of certificates (p<0.01), and whether food service workers is students' parents or not (p<0.01). In addition, the sanitation-performance-degree levels of a few sanitation management items were significantly different according to their food sanitation knowledge level, working time, and whether food service workers is students' parents or not. In conclusion, these factors that improve food service sanitation should be fully considered when food service workers are hired or when food service management policies are established. Additionally, sanitation education and training for school food service workers should be offered regularly with effective education media.

최근 국가가 공인하는 인증기관에서 발행하는 공인인증서를 폐지하고 인터넷 기업이 자체적으로 공동인증서를 발급하면서 그 책임을 부여하는 방법으로 전자서명법이 개정되었다. 인터넷 기업이 인증기관으로서 발행하는 공동 인증서의 사용이 허용되면서 공개키 인증서 도용에 따른 사기 피해의 확대가 예상된다. 무결성과 보안성이 내재된 블록체인에 PKI를 결합한 보안 게이트웨이에서 사용할 수 있는 인증 모델을 제안하였다. 제안 모델의 실용성 평가를 위해서 전문가 집단을 활용한 델파이 기법으로 중요도를 도출하고 인간의 주관성을 배제하는 평가방법인 수게노의 계층퍼지적분을 이용한 인증 모델의 보안성을 평가했다. 블록체인 기반 공동인증서는 무분별한 공인인증서의 발행과 오남용을 방지하고 보안성과 편의성이 확보된 서비스의 기반기술로 활용이 기대된다.

This study examined differences in consumers' images of short-term income forest products, preference, willingness to pay prices and purchase behavior according to dietary lifestyle as well as investigated what factors influence the degree of satisfaction when purchasing short-term income forest products and willingness to repurchase. According to dietary lifestyle, the results classified consumers as 'frugal housewife type,' 'convenience-seeking type,' and 'food high-involvement type.' A 'food high-involvement group' is defined as a group that wants high quality products regardless of price. In the 'frugal housewife type,' country of origin and hygiene/safety (considered when purchasing food) had positive influences on the degree of satisfaction. In the 'convenience-seeking type,' country of origin (considered when purchasing food) had a positive influence on the degree of satisfaction while country of origin (checked when purchasing food) had a negative influence on degree of satisfaction. Consumers had a lack of perception for short-term income forest products; subsequently, short-term income forest products had a weakness of low access to consumers. Therefore, farms for short-term income forest products need to divide products into 'high-priced' luxury products and 'low-priced' frugal products according to dietary lifestyle characteristics, improve packaging status to enable consumers to check quality certificates, and clearly indicate country of origin as well as improve distribution processes and increase consumer access to products.
