As the utilize of personal health records increases in recent years, research on cryptographic protocol for protecting personal information of personal health records has been actively conducted. Currently, personal health records are commonly encrypted and outsourced to the cloud. However, this method is limited in verifying the integrity of personal health records, and there is a problem with poor data availability because it is essential to use it in decryption. To solve this problem, this paper proposes a verifiable cloud-based personal health record management scheme using Redactable signature scheme and zero-knowledge proof. Verifiable cloud-based personal health record management scheme can be used to verify the integrity of the original document while preserving privacy by deleting sensitive information by using Redactable signature scheme, and to verify that the redacted document has not been deleted or modified except for the deleted part of the original document by using the zero-knowledge proof. In addition, it is designed to increase the availability of data than the existing management schemes by designing to recover deleted parts only when necessary through the Redact Recovery Authority. And we propose a verifiable cloud-based personal health record management model using the proposed scheme, and analysed its efficiency by implementing the proposed scheme.

Compared to the word "memory" in general, the word "record" can be unfamiliar. This study addressed the problem that elementary school students do not have enough learning opportunities due to the lack of content on records in the curriculum. An educational program using Korea's UNESCO Memory of the world was conducted for three classes of 6th graders at J Elementary School, and the effect of the program was analyzed by administering pre- and post-surveys to students and in-depth interviews to teachers. The results of the student survey showed a significant improvement in their understanding, knowledge, satisfaction with the lessons, and need for records and Korean UNESCO Memory of the world. Teacher interviews confirmed the effect of the program, but suggested that it should be adjusted to fit the limited time available. Based on this, we verified the effect of the developed program and suggested directions for improvement of future record education programs.

The purpose of this study was to investigate the relationships between lifestyle types, demographic variables, and clothing consumption orientations of male and female adolescents. The method of this study was a survey research by using questionnaires. Subjects were 393 high school students in Seoul. Four lifestyle types of adolescents were derived by cluster analysis: 'digital orientation type', 'material orientation type', 'positive enterprise type', and 'achievement orientation type'. The material oriented students spent high expense on clothes, had higher preference of imported products, had more sensuous consumption orientations, did more impulsive buying, and were more influenced by advertisements than other types of students. Digital oriented students had mothers with low educational background, low academic records, spent small expense on clothes, and had less sensuous consumption orientation. There were more male students than female students in positive enterprise type and the students of this type had upper middle academic records, had higher sensuous consumption orientation and did less impulsive buying. There were more female students than male students in achievement oriented type and this type had high academic records, had mothers with high educational background, and spent small expense on clothes. They had low level on most of the clothing consumption orientation and were especially less influenced by advertisement. This research confirms that the clothing consumption orientations are associated with the lifestyle of adolescent.

This study intends to evaluate the quality of the Digital Library System DB and to suggest methods for its quality control. The evaluation criteria are hit rates, redundancy, completeness and accuracy. In spite of high hit rates excessive records representing one work resulted serious redundancy. The average completeness rate of records was $48.12\%$ due to low level of description. The Analysis of accuracy showed various errors in most of records corresponding to $92\%$. Emphasis on analysing the errors in detail detected the causing factors and suggested practical guidelines for school libraries' catalogers.

Domain name system (DNS) is a primary identification mechanism for Internet applications. However, DNS resolutions often take an unbearably long time, and this could seriously impair the consistency of the service quality of Internet applications based on DNS such as World Wide Web. Several approaches reduce DNS resolution time by proactively refreshing expired cached records or prefetching available records beforehand, but these approaches have an inherent problem in that they cause additional DNS traffic. In this paper, we propose a DNS resolution time reduction scheme, named renewal using piggyback (RUP), which refreshes expired cached records by piggybacking them onto solicited DNS queries instead of by issuing additional DNS queries. This method decreases both DNS resolution time and DNS traffic since it reduces the number of queries generated to handle a given DNS resolution without generating additional DNS messages. Simulation results based on two large independent DNS traces show that our proposed approach much reduces not only the DNS resolution time but also the DNS traffic.

Most of disabled people face hardness in caring their general oral hygiene by themselves. So that, they are once involved in dental caries or periodontal disease, they have much bigger chance of aggressive progress. Therefore preventive dentistry is more important to disabled one than non-disabled. They need to be checked with routine periodic dental examination and by that, oral disease must be found at initial stage. We selected 37 patients from newly visited 237 patients who had dental treatment at the free dental clinic, Gangnam district, Seoul, between 2000 and 2001. This study is a comparative evaluation of first 2 years' treatment records of selected 37 patients (male 28, female 9) with that of their last 2 years. 24 of 37 have mental retardation, 9 have autistic disorder, 2 have auditory disorder, 1 has brain disorder and 1 has crippled disorder. Their dental treatment records categorized by 4 level; score 4 stands for endodontic treatment, score 3 stands for general conservative treatment, score 2 stands for preventive treatment, such as sealant and score 1 stands for routine check. In first 2 years of treatment, average score was 2.85 which score means approximately general conservative treatment. And that of last 2 years was 1.44, which means routine check. In early time of their visit, they will receive the treatment due to their chief complaint. And after that early time, they can have a routine check so that they can be treated before the disease get worse. The patient's oral health can remain decent only by a simple treatment.

Overflowing of fashion information that is derived from the development of various mass media has rather hindered adopters from appropriately screening fashion information. Thus, responsibilities of fashion journalists who play a role of communicating fashion information have become heavier. Fashion journalism may be defined as 'delivery of modes and involvement in production and logistics'. Since it connects fashion and culture industries with the public by reflecting fashion from diversified perspectives, the role of fashion journalism should never be overlooked in terms of culture as well as industry. This study analyzes fashion journalism from fashion-advanced country by reviewing the fashion journalism from the US, which is so-called fashion-advanced country and analyzing the contents of Vogue USA. This study made a historical review of fashion journalism through a reference study, and from a total of 24 volumes of Vogue USA from January 2004 through December 2005 classified articles by functions, tones, contents, and brands, pictorial records by functions, images, and brands, and ads by brands, quantitatively analyzing them. Further, through a case study it explored those articles and pictorial records which featured national characteristics in the USA, and examined how the fashion journalism in the USA imaged the fashion in the country. In addition, it tried to elicit the characteristics of fashion in the USA as a conclusion by categorizing those images while reviewing previous studies. The results show that Vogue USA features American fashion definitely. Thus, consequently it is easy to find images of American fashion in pictorial records, let alone categorizing them.

The Functional Requirements for Bibliographic Records (FRBR) is a 'conceptual model of the bibliographic universe' developed by the International Federation of Library Associations and Institutions (IFLA). Although some studies have suggested improvements in FRBR, and others explore alternative approaches, less attention has been paid to analyzing the internal coherence and consistency of the FRBR view as presented not only in the FRBR entity-relationship model and text of the FRBR document, but also in the related explanations and presentations of FRBR expositors. Our investigations have noted some interesting discrepancies between the general FRBR approach as presented in various expository documents and the specific account presented in the FRBR ER model and the FRBR document. We see that in one case these discrepancies can be easily remedied by adding additional modeling constructs and assertions, but in another case (the supposed 'inheritance' of attributes across the Group 1 entities), there is a substantial difficulty in maintaining a consistent model. We discuss several alternative approaches to enhancing the expressiveness of FRBR in order remedy this problem. We note that none is entirely satisfactory.

Objectives: The valid assessment of food and nutrients intakes using appropriate dietary intake method is necessary to improve the nutritional status of the hemodialysis (HD) patients. This study was conducted to compare the method between newly developed, semi-quantitative food frequency questionnaire (Semi-FFQ) and 7-day dietary records (7-DRs) for hemodialysis patients. Methods: We conducted both methods on 53 maintenance HD patients in two university hospitals. We calibrated the frequency, portion size and daily intake of 47 food items reported in Semi-FFQ. The food and nutrients intake was compared and the correlation of the two methods was analyzed. Also each nutrient intake was compared to recommended dietary allowance for Korean (KDRIs) and recommended nutrient reference value for HD patients. Results: Energy and energy-yielding nutrients intakes were significantly higher in the two methods (p<0.01). These support the possible reliability between Semi-FFQ and 7-DRs that is similar with regard to most mineral and vitamin intakes. Thus, the Semi-FFQ used in this study for the assessment of nutrient intakes of HD patients can be reliable for the assessment of the nutrient intake along with the 7-DRs. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol than for those of foods eaten rarely (p<0.01). Conclusions: The Semi-FFQ used in this study can be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-DRs, despite its limitations.

One of the problems facing in all modern dental hospitals is the much efforts, manpower and space are needed to effectively sort and stack patients' charts of the various dental departments. In addition, the storage and prompt arrangement of x-ray films is also a problem. Therefore, if dental charts as well as films could be computerized, it would be easier to store and keep them; by data basing, many space, manpower and cost would be saved: data could also be effectively managed for the purpose of academic researches. This would be an epoch -making event in the development of dental hospital management. The purpose of this study is to develop a dental information processing program, that will be used to store dental treatment records and digital image data using a new record media, the optical card. The patients' charts from the dental hospital were selected. The treatment records of the chart were put into the treatment data -recording area of the program, and the digital images of various dental x-ray films were made with a scanner. These data were stored in the optical card and analyzed to get the following results: 1. In this program it is possible to put treatment records and image data into and out from the optical card, and it is impossible to correct and delete all data recorded on the optical card. 2. All data in the optical card system can be searched and analyzed on database. 3. The resolution of image data stored in optical card is above 5.9 lp/mm. 4, All data of dental charts used as samples, stored to optical cards, occupies average 14%, In conclusion, with the development of the storage system using the optical card, a dental patient's life-time treatment record can be stored in one optical card and used as a substitute for the dental chart.
