자망이나 삼중자망은 그물에 고기가 꽂히거나 얽히게 하여 어획하는 어법이다. 흐름이 있는 곳에서 어구는 저항을 받게 되고, 이에 따라 형성되는 어구 형상은 유속 세기와 부력 및 사용된 그물의 망지 길이(뻗친 높이)와 관련된다(장ㆍ서, 1982; 천상, 1981; 송전, 2001). 이때 자망의 높이는 어획 효율에 영향을 미치는 매우 중요한 요소이다. 저자망의 경우 뜸줄의 높이는 바다에서 다이버나 자기기록식 기록계에 의해 기록되거나 flume tank에서 여러 가지 망목크기와 길이 및 망사직경에 대해 조사된 바가 있다 (Matuda, 1988; Stewart, 1988).

In this study, we propose a logical transfer method of records using cloud storage to solve the integrity problem of digital component, which is generated when electronic records are transferred from the electronic record production system to the record management system. This method, which produces electronic records using cloud storage from the production stage and transfers them to the archives, has the following advantages. First, as a record management method, it can be effectively applied in public institutions by utilizing cloud computing technology, which has been the trend recently. Second, unlike the existing method of copying and physically transferring electronic records, the proposed method can reduce various risk factors that may occur in the transfer of electronic records by logically transferring the storage. Third, the method can prevent errors of the digital component according to the physical transfer of the electronic record; hence, the integrity of the electronic record can be guaranteed. Fourth, administrative power and cost that are wasted because of the electronic transfer of electronic records can be reduced.

A fast foot of information communication technology is appearing as expansion of prompt administrative service desire and national participation desire regarding administration. This is following again by government innovation and demand of customer-oriented governmental implementation with information technology. The Ministries of Education and Human Resources Development proceeded with National Education Information System(NEIS) for the aim of educational informatization at a highest global level. NEIS that was operated from 2003 established a system in Educational Offices in 16 cities/province and the Ministry of Education and Human Resources Development, and connected all educational administration organizations and primary and middle schools with Internet. Thus, NEIS processes electronically the general administration affairs in educational administration organizations each unit school. The NEIS school affairs business system that is newly enforced is producing an important documentation (of semi-permanent level) such as personal information and grade of students including School Human Document with electronic methods. However, we need to guarantee authenticity, integrity, reliability and usability of documentation because school affairs business system is producing important documentation under poor circumstances. According to this necessity, school affairs business system analyzed how many a record management function includes by the ISO 15489 that was an international record managerial standard. On the basis of these analyses, I will present a plan for management of a school documentation in this study. These researches are meaningful in electronically analyzing a record management function of the National Education Information System(NEIS) and in documentarily approaching management plan. I expect theses researches to be able to used as useful data for documental management plan preparations regarding a productive documentation of all kinds of business systems using in public institutions as well as National Education Information System(NEIS).

This study aims to explore practicable and sustainable strategies for locality documentation through networking, linking, and recontextualization of records in digital environments. It applies the 'spanDoc(SPAace-based Networked Documentation) Model to document Donghae-Nambu Railway areas placed in Busan Metropolitan City tentatively. Considering that mobility and openness are the main characteristics of Busan, railway areas and their stations can be proper places for representing such localities of the city. Moreover, there can be much experiences and memories of residents surrounding those areas, because Donghae-Nambu Railway has been used as short distance transportation facilities across the inner city of Busan since 1930's. This study tries to implement the documentation strategy for the selected space, following the procedures of the spanDoc Model. Firstly, this study develops the structure of the subjects through investigating the related information sources and archives from various collecting institutions. Secondly, it carries out records surveys to identify the essential records types for documenting the Donghae-Nambu Railway areas. Thirdly, it describes the subjects and sub-subjects, and the entries of places, people and subjects for adding to the dictionaries. Finally, it links many entities such as subjects, records, and dictionary, and builds the databases regarding the inter-links and systematic accumulation of the outputs of each step.

The functional requirements standards for electronic records management systems which have been published recently describe the specifications very precisely including not only core functions of records management but also the function of system management and optional modules. The fact that these functional requirements standards seem to be similar to each other in terms of the content of functions described in the standards is linked to the global standardization trends in the practical area of electronic records. In addition, these functional requirements standards which have been built upon with collaboration of archivists from many national archives, IT specialists, consultants and records management applications vendors result in not only obtaining high quality but also establishing the condition that the standards could be the certificate criteria easily. Though there might be a lot of different ways and approaches to benchmark the functional requirements standards developed from advanced electronic records management practice, this paper is showing the possibility and meaningful business cases of gaining useful practical ideas learned from imaging electronic records management practices related to the functional requirements standards. The business cases are explored central functions of records management and the intellectual control of the records such as classification scheme or disposal schedules. The first example is related to the classification scheme. Should the records classification be fixed at same number of level? Should a record item be filed only at the last node of classification scheme? The second example addresses a precise disposition schedule which is able to impose the event-driven chronological retention period to records and which could be operated using a inheritance concept between the parent nodes and child nodes in classification scheme. The third example shows the usage of the function which holds or freeze and release the records required to keep as evidence to comply with compliance like e-Discovery or the risk management of organizations under the premise that the records management should be the basis for the legal compliance. The last case shows some cases for bulk batch operation required if the records manager can use the ERMS as their useful tool. It is needed that the records managers are able to understand and interpret the specifications of functional requirements standards for ERMS in the practical view point, and to review the standards and extract required specifications for upgrading their own ERMS. The National Archives of Korea should provide various stakeholders with a sound basis for them to implement effective and efficient electronic records management practices through expanding the usage scope of the functional requirements standard for ERMS and making the common understanding about its implications.

While relevant studies emphasize the significance of user-oriented indexing associated with fulfilling both topical and non-topical needs of individual users, a great number of operational retrieval systems supports only those searches related to subject attributes of the users' needs. Retrieval systems for presidential image collections are not an exception for such a restriction. Upon this reality. this study seeks diversification of access points for presidential images based on descriptors directly presented by potential user groups. Improvements of subject-based descriptors are suggested based on those descriptors identified.
