The method for analyzing the recording and reading process of magnetic recording system by numerical simulation is introduced. which can simulate the effect of elements of the magnetic recording system. During the whole simulation, hysteresis characteristics must be included. Preisach model and finite element method are used to construct the algorithm. From the wave of recording current, recorded pattern of magnetization in recording media is simulated in recording process, and then waveform of reading signal in head coil is obtained in reading process. To show the validity of this method, this is applied to perpendicular magnetic recording system. Waveform of recording signal and reproduced signal is obtained in several density. Pattern of reprocuced voltage magnitude according to increase of recording density shows roll-off curve.

This archiving project of the survivors of suicide was done with the survivor supporting team of the Seoul Suicide Prevention Center. The survivor supporting team was operating a Self-help Support Group for the emotional support of the survivors of suicide. A Self-help Support Group is a place for the survivors of suicide to regularly meet and share their suffering by talking of topics hard to discuss elsewhere. As the Self-help Support Group progressed members who acted as the leader of the group appeared. They formed an essay group that writes together. Two fathers who lost their sons, two mothers who lost their daughters, a mother who lost her son, a wife who lost his husband. The essay group met each week in a place facing Sajik Park. Through the windows that took up the whole side of the room, evening was coming in. The things that happened during the day went away towards Inwang mountain following the setting sun. Ten people (six members of the essay group, three from the survivor support team, a historian for unique conversation) sat around a table, facing each other. "Now, what shall we do?" History for unique conversation is a time that archives life by sharing conversations. At times a complete stranger, and other times people who share their ordinary lives sit around together (3-9 people, sometimes about 15). On the table there is coffee, bread, fruits and salads, and sometimes a dish someone heartily prepared. When a bottle of wine is placed on the table, each takes a glass. Morning, afternoon, the time the evening is welcomed in, late night. It does not matter which. For six months, 3 hours when meeting every week, 6 hours when at every other week. A room where the ambience is like that of a kitchen where sunlight enters, or a cozy living room is the best location. However, there are many times when it is held in a multipurpose room in the suburbs where many meetings are held, or in a classroom of a school. The meeting place is decided according to different situations of the time. There are no participation requirements as it is said to be for themselves to write down according to archiving form while looking back their lives thoroughly, and they are the only ones to stop themselves. The archives landscape from far away would seem like trying to do some talking. However, when going into a microscopic situation one must leave themselves to the emotional dynamics. It is because it archives the frustration and failures one experienced through life. A participator of history for unique conversation must face the sufferings of their life. The archiving project took place in 2013 to 2014. Many years have passed. Has the objective distance for archiving the situation of that time been secured? That may be uncertain, but I will speak of a few stray thoughts on archiving while depicting the process and method of operation.

COVID-19 Archives are some of the Disaster Archives. It is necessary to collect disaster records produced in real-time at the disaster scene rather than start collecting records after the disaster recovery. Therefore, this study summarized the definition and purpose of disaster archives to understand the current status of domestic and foreign COVID-19 archives and examined overseas disaster archive collection policies that can be referenced in establishing a COVID-19 archive collection policy. In addition, surveys and interviews were conducted on institutions that establish and operate related archives at home and abroad. As a result, record collection Improvement plans for the COVID-19 archive were proposed: Firstly, in terms of collection policy improvements, the essential elements identified in the survey were selected as additional collection policy elements. Secondly, diversification of participants' groups requires the introduction of clear definitions of collection targets, diversification of promotional methods such as recording record contents through collaboration with related departments, and improving copyright issues that limit record donation. Thirdly, participatory record collection methods with efficient questionnaires in participatory forms and privacy issues are proposed as improvement plans.

An interest in various description of history was increased, resolutely breaking away from the existing frame also in a historical science world, under the influence of post-modernism arisen from the mid 20th century, and for this, oral history archives and oral history methodology began to attract the attention in various academia including archival science as a method for a new writing of history. Also, under the circumstance of korea having a difficulty in performing a whole reconstruction of modern age history and a liquidation of past affairs due to an absolute lack of archives, the tendency is toward more active management of oral history archives and establishing oral history archives in the context of an excavation of new archives and a reinterpretation of history, owing to the necessity in a particular situation. This article started with a critical mind regarding an absence of a collecting policy which can help an effective development of collection from a point of view of archival science, with regard to oral history archives that recently shows a rapid increase of an interest. For this, this article intended to present an new element of a collecting policy besides the study on a collecting policy performed meanwhile by an archival science world by noticing a characteristic and a collecting method of oral history archives, this can be examined largely through 'a statement of mission and collection purpose', 'a policy of collection at large', 'a definition of maintenance and use of the holdings', and 'a guide for a development of collection', and add a proposal regarding a plan to embody the parr which should be actually applied to collection of oral history archives among the existing constituents.

A topic map was designed as an efficient information retrieval method that is optimized for classification, organization, and navigation through the use of a semantic link network above information resources. With this, this study aims to design a topic map-based university archives retrieval system to provide the relevant information retrieval. For this study, electronic records that relate to the academic administration within two years of D university were collected, and topic map editing was carried out with Ontopia Omnigator. Topics were classified according to their functional analysis of academic administration. In the end, the number of topics was finalized as 626, with 6 types in general: academic work, staff, college register, student, university, etc. Association was separated into six types as well, which were formed with consideration to the relationships among topics. In addition, there are seven occurrence types: register class, register number, register date, receiver, title, creator, and identifier. It is expected that the associative nature of the designed topic map-based retrieval system in this study will make navigation of large records easy and allow incidental discovery of knowledge.

기네스 기록과 같은 기록정보는 사용자가 질의응답 시스템에 자주 질문할 수 있는 내용이지만, 구성단어의 수가 적고 일반적인 단어로 구성되는 기록정보 문장의 특성으로 인해 전통적인 질의응답 시스템에서는 정답을 제시하기 힘든 정보이다. 그러므로 기록정보만을 위한 접근방법이 필요하다. 우리는 기록정보는 특정 문맥에 의해 쓰여지는 경우가 많다는 가정 하에, 문맥 정보를 반영할 수 있는 템플릿을 정의하고, 이 템플릿에 의해서 기록정보를 색인하여 정답을 제시하는 시스템을 제안한다. 템플릿은 거리, 형태소, 형태 소품사, 정답유형, 구문 정보의 5가지 제약정보를 나타낼 수 있게 구성된다. 전통적인 백과사전 QA 시스템과 제안 시스템을 비교하여 평가한 결과, 제안한 방법이 기록정보 QA 시스템에 효과적임을 알 수 있었다.
