Illegal and harmful contents on the Internet has been an issue and been increased in Korea. They are often posted on the billboard and website of small enterprise and government office. Those illegal and harmful contents can relate to crime and suspicious activity, so, we need a detection system. However, to date the detection itself has been conducted manually by a person. In this paper, we develop an automated URL detection scheme for detecting a drug trafficking by using Google. This system works by analyzing the frequently used keywords in a drug trafficking and generate a keyword dictionary to store words for future search. The suspected drug trafficking URL are automatically collected based on the keyword dictionary by using Google search engine. The suspicious URL can be detected by classifying and numbering each domain from the collection of the suspected URL. This proposed automated URL detection can be an effective solution for detecting a drug trafficking, also reducing time and effort consumed by human-based URL detection.

It is unsuitable for Korean coastal information to work specific tasks because the coastal information of the current provides simple information, and thus the coastal information is required to reprocess. Therefore, this paper intends to present the ontology model for managing the coastal information using Geo-Ontology and seek application of ontology. The contents of this paper follow as; First of all, I considered the base theories for ontology and related researches. Second, I built Geo-Ontology which defines taxonomy of geographical features and their relationships. Third, I designed and implemented the coastal information ontology about basin of coast, Masan, using Geo-Ontology. Fourth, I carried out semantic queries and reasoning, assessment of the coastal information ontology. This paper will be a base study for many projects which are currently being conducted to integrate spatial information for more effective administrative works and easier maintenance and management of data. Also, this paper is significant in the sense that it is the study preparing for linked data.

This study aims to suggest measures for handling copyright information on government publications during records and archives management to use them freely as public works according to Article 24-2 of the Copyright Act in Korea. Through email interviews with 17 records managers, persons in charge of government publication management, and government staff with experience in production from April 4 to June 13, 2022, this study determined the current situations and problems related to producing and managing copyright information on government publications. Based on the interview findings, this research suggested the following. First, Article 24-2 of the Copyright Act must be revised to apply the Korea Open Government License (KOGL) type 1 mandatorily to all public works. Second, a cooperative system for managing copyright information on government publications should be established to improve their production and management effectiveness. Third, copyright information, such as authors, copyright holders, copyright duration, information on the copyright property transfer, public works status, and reasons for nonpublic works, must be managed through records and archives management systems. Fourth and last, information on public works must be provided during the registration number application for government publication so that everyone can access the full texts of the publications on the National Archives of Korea website.

Recently, data sharing between enterprises or organizations is required matter for task cooperation. In this process, when the enterprise opens its database to the affiliates, it can be occurred to problem leaked sensitive information. To resolve this problem it is needed to hide sensitive information from the database. Previous research hiding sensitive information applied different heuristic algorithms to maintain quality of the database. But there have been few studies analyzing the effects on the items modified during the hiding process and trying to minimize the hided items. This paper suggests eFP-Tree(Extended Frequent Pattern Tree) based FP-Tree(Frequent Pattern Tree) to hide sensitive frequent itemsets. Node formation of eFP-Tree uses border to minimize impacts of non sensitive frequent itemsets in hiding process, by organizing all transaction, sensitive and border information differently to before. As a result to apply eFP-Tree to the example transaction database, the lost items were less than 10%, proving it is more effective than the existing algorithm and maintain the quality of database to the optimal.

One of the features of record management during the Gabo Reform is that the documents office controled producing and distribution of records. The records completed the operations were sent the record office and classified and arranged. previous researches understood this record management system during Gabo Reform were introduced from Japan. This article clarifies that new record management system settled through Meiji Restoration were introduced from German(Prussian) registry system at the time. However, German registry system managed current records and this system was based on modern record management system which open the records to the public with archives. Japan accepted only registry system, current record management system of German, and didn't established archives at Meiji regime. It is same with Joseon Dynasty during the Gabo Reform regime. Therefore, the record related regulation at the Gabo Reform regime could not be judged to be a modern system. The regulations on records at Gabo Reform regime had no terms about people's right or open the records to the public which decides modern record regulations. The meaning of record system during Gabo Reform regime is that the value of records and name of organizations coincides with record life cycle. The documents office managed current records and record office classified and filed closed records. Concept of "current record=document=documents office, non-current record=record= record office" didn't succeed to today. The term 'record' is used as current record or non-current record without difference.

Information technology is being applied to the development of ubiquitous healthcare system, which provides both efficient patient care and convenient treatment regardless of patient's location. However, the increasing number of users and medical information give rise to the problem of user management and the infringement of privacy. In order to address this problem we propose a user access scheme based on the RBAC (Role Based Access Control) model. The preceding trust management model for Grid security, FAS(Federation Agent Server), was analyzed and extended to provide supplementary functions for role-based access control in u-Healthcare system. The RBAC model provides efficient user management and access control, but very vulnerable in case when one with valid role tries to leak confidential inner medical information. In order to resolve this problem, a RBAC-WS (Work Status with RBAC) model has been additionally developed which allows only qualified staffs to access the system while on duty. Th proposed RBAC and RBAC-WS model have been merged together and applied to the PACS (Picture Archiving and Communication System).

우리나라의 전기요금제도는 각종 정책적 요인을 반영하면서 형성되어 왔으므로 근본적인 가격결정원칙이 결여되고 있으며 가격결정의 일반원칙에 비추어 볼때 여러 문제점들이 노출되고 있다. 본호에서는 현행 전기요금구조의 개선방안으로서 주택용 전기요금의 누진구조 완화, 업무용 전기요금의 1, 2종 구분폐지, 산업용 최대부하요금의 시간대 구분변경 및 요금차등률의 적정화, 그리고 기본요금 비중의 조정을 제안하고 있다. 또한, 전기사업의 새로운 여건변화에 부합하는 장기적인 전기요금 정책방향을 다음과 같이 제시하고 있다. 첫째, 에너지 경합시대에 대응하는 시장경쟁형 전기가격 결정원칙으로서 한계비용 가격원칙의 채택이 필요하다. 둘째, 수요관리형 전기가격 정책방안으로서 최대부하 요금제도의 확대적용, 소비자 선택형 요금제도의 실시, 그리고 전전화 수요가요금제도의 도입에 과한 정책검토가 요망된다. 셋째, 전기요금수준적정화를 위해서는 정책적요인에 의한 전기가격 왜곡요인 배제, 독점기업으로서의 전기사업자의 비효율성 해소, 투자정보율 규제에 대신하는 전기사업자의 합리화 인센티브 규제, 경영부실에 기인하는 비용증대 부분의 불인정, 이시점간설비투자비의 적정배분등을 통하여 전기요금수준인하를 모색하여야겠다. 끝으로 전기요금 개정시 이해당사자들의 견해를 공개적으로 반영시킬 수 있도록 전기가격 조정심의기구와 같은 제도적 장치이 설치가 요망된다.
