수많은 데이터를 사용하는 기업 및 기관들은 전용 데이터베이스를 구축하여 모든 정보들을 저장, 관리하고 있다. 개인정보를 포함하여 비인가된 중요 정보들이 저장되어있음에도 불구하고 대부분의 경우 데이터베이스에 대한 보안적용이 되어있지 않거나 아주 미비한 상태이다. 보안사고의 대부분이 데이터베이스에 저장된 중요 정보가 유출되는 점을 보았을 때 데이터베이스 자체에 대한 보안시스템을 구축하여 예방하는 것이 보안사고의 피해를 막을 수 있는 가장 핵심적인 방법이라 할 수 있다. 이에 본 연구에서는 네트워크 패킷을 모니터링하여 데이터베이스의 성능에 영향을 미치지 않고 보안기능을 수행할 수 있는 Sniffing 을 이용한 방안을 제안한다. 제안 보안시스템은 별도의 하드웨어에서 기능을 수행하며 운영 중인 데이터베이스에 서비스의 중단 없이 보안시스템을 구축할 수 있도록 하였다. Sniffing 방식에서 접근제어 기능을 수행 할 수 있도록 알고리즘 설계를 하였으며 감사 로그를 기록할 때 가장 많은 부분을 차지하는 SQL 에 대해 MD5 해시함수를 적용하여 해당 로그에 대한 데이터크기를 크게 줄일 수 있었다. 운영중인 데이터베이스 환경에 영향을 주지 않으면서 높은 수준의 감사성능을 제공하고 다양한 보안 정책을 간단하게 적용할 수 있도록 구현하였으므로 데이터베이스에 저장된 중요정보의 유출을 예방하고, 보안사고가 일어났을 때 추적 및 증거자료로 활용할 수 있을 것이다.

The memorial stones of Sumanotap were known to have been sequentially produced in 1719, 1773, 1874, 1653, 1874. However, after examining the chronological era (年號) and sexagesimal cycle (干支), it was found that the second and fourth memorial stones were both recorded in 1713. The reason why the records of the same period were divided into two is assumed that since the subject to repair was divided into main structure and flagpole of the temple, and it was recorded per each monk in charge and donator. On the fifth tablet of the memorial stone of Sumanotap contains all the names of monks who were in charge of repairing Sumanotap as well as the names of common donators. These people are not verified in detail though, through comparing the Buddhist names on the third memorial stone with Buddhist paintings and painting records, 12 monks were identified to be in the same names. Generally, they were active in Gangwon province, Gyeongsang province, Seoul and Gyeonggi province in the late 19th century and even after the Sumanotap repair, they took up other duties of various temples. The most notable name among the donators recorded in the memorial stones of Sumanotap was Kim Jwageun. He was the donator for the chest of gold and silver that was enshrined in the pagoda in 1874. His name was recorded with Mrs. Yang from Cheongsin and, at that time, was known just as a donator. However, actually, the donator was not Kim Jwageun but his mistress Mrs. Yang who used to be a gisaeng, called Na-hap and was from Naju. Kim Jwageun deceased in 1869 already. It is exceptional that Mrs. Yang who were the mistress of the prime minister Kim Jwageun personally participated in the Buddhist event in which king, queen, mothers of king and queen, noblewoman participated. Besides, the event of Sumanotap repair was carried out by royal family in order to celebrate the hundredth day of the prince, Sunjong and his grandfather, Heungseon Daewongun did not participate for political reason. In this situation, the domination of Mrs. Yang is considered remarkable. Meanwhile, the temples that frequently appeared among the 10 temples recorded in the memorial stone of Sumanotap are Gakhwa-sa temple in Bonghwa-gun, Gyeongsangbuk-do and Bodeok-sa temple in Yeongwolgun, Gangwon-do. Gakhwa-sa temple was a temple where the historical achievements were kept so was under the government's control. Bodeok-sa temple was the buddhist temple praying for the soul of the Danjong buried in the tomb and was managed by the government. Therefore, the face these two temples participated in the Sumanotap repair proves that Sumanotap was repaired by the supports form these two temples and the stature of Sumanotap at that time was as high as the temples where the historical achievements are store or the royal buddhist temples for praying for ancestors' souls.

This research was attempted to understand the types of the subjectivities possessed by the individuals regarding the management of the health of the skin on the part of the female university students by applying the Q-methodology and to comparatively analyze the special features. Regarding the subjects of the research, 41 female university students at one university were made into the P-samples. And, by selecting 34 Q-samples from the total of 141 Q-populations, the forced distribution took place in terms of the 9-points scale. The subjects were interviewed, and the contents regarding interviews were recorded. The data were analyzed with the QUANL program. As a result of the research, the 4 types were discovered. They appeared as 'the professional knowledge pursuing type', who consider the expertise regarding the skin management important, 'the nature-oriented type', who express the importance of the skin rather than the functional, cosmetic products, 'the active self- management type', who pursue the highly-functional cosmetic products and the active skin management, and 'the self-ostentation type', who consider the external parts, rather than the health, important. As a result, based on the results of this research, the special characteristics by each type regarding the skin health management of the female university students must be understood, and a differentiated educational method or approach method for the skin health management resulting this must be considered.

This study was performed to investigate knowledge, attitudes and related behavior on the food hygiene and safety management of school food-service programs among mothers and to find factors affecting their knowledge, attitudes and behavior. A self-administered questionnaire was offered to a random sample of 301 mothers who have children attending elementary schools in one region of Korea. The survey was carried out over a two-month period (April-May,2001). They had lower behavior scores compared to the scores of knowledge and attitudes (p〈0.05). The micro levels of the knowledge, attitudes and behavior scores also showed the same tendency. Logistic regression analysis showed that mothers' education level affected their knowledge and attitudes, while the participating activity in school food-service programs affected their behavior the most frequently. Pearson's correlation analysis confirmed that the knowledge and attitude scores were significantly correlated (r=0.61404, p〈0.001). The results indicate that the knowledge and attitude levels of mothers regarding the food hygiene and safety of school food-service programs were good, however, their behavior levels were not satisfactory. The findings highlight the importance of participating programs in school food-service programs to close gaps between the behavior and knowledge or attitudes of mothers and to improve their behavior levels.

Composite and compact devices equipped with the functionality of digital still image acquisition, such as cellular phones and MP3 players are widely available to common users. In addition, the application of digital still images is becoming common among security and digital recording devices. The amount of still images, that are maintained or shared in personal storage or massive storage provided by various web services, are rapidly increasing. These still images are bound with file names or identifiers that are provided arbitrarily by users or that are generated from device specific naming method. However, those identifiers are vulnerable for unexpected changing or eliminating so that it becomes a problem in still image search or management. In this paper, we propose a method for still image identifier generation that is created from the still image internal information.

Protection of personal information has significant meaning in current information age. Information of crime victim is one of top in value in that divulgence of the information to perpetrators may threat safety of the victim or cause psychological demage as $2^{nd}$ harm if disclosed to public. Legal system protects the information with scattered statutes including Criminal Procedure Act. Existing studies have been limited to discussion of the single statute without integrated approach. Bearing necessity of the approach in mind, as issues of protection system this research proffers too broad subject of eligible inspection of case document, inactive practice of identity management cards and omission of personal information, and inappropriate punishment on the disclosure or divulgence. After reviewing systems of foreign jurisdictions to get useful implications, this paper suggests several measures with two separate aspect of legal provisions and protection practice.

Recently, research about an electronic attendance-absence recording system has been actively carried out using smart devices. Using an electronic attendance-absence recording system, professors can check their students' attendance on a real-time basis and manage their attendance records. In this paper, we proposed a real-time electronic attendance-absence recording system using face detection and face recognition based on web application. It can solve the spatial, temporal, cost issues belong to electronic attendance-absence recording system using AIDC(Automatic Identification and Data Capture). A proposed system is running on web server and made by HTML5(Hyper Text Markup Language ver.5). So professor connect to server using mobile web browser on mobile device and real-time manage electronic attendance-absence recording with real-time send or receive image data. In addition, the proposed system has an advantage capable of installation and operation, regardless of the operating system because it operates based on the Python flask framework.
