Since the legislation of the act for public records, there has been a remarkable growth in records management in Korea. Recently, how to efficiently handle digital records has become an urgent issue in Korea. However, the appraisal process for (selection) archives seems inappropriate. This study reviewed the problems of each archiving process for records created by police departments and prosecutors' offices. Based on the results of the review, I proposed an improvement plan for the selective and appraisal acquisition of records.

항생제 생산을 위한 생물공정은 크게 3단계로 나뉠 수 있다. 우주균주 선발, 현장균주 보존및 현장 종균 공급을 위한 일련의 종균배양 과정을 Upstream이라 할 수 있고, 종모실로 부터 공급받은 종균을 현장에서 증식시키는 현장 종균배양 공정과 본 발효조에서의 항생제 생합성공정을 Mid-Stream, 발효가 끝난 상태의 배양액으로부터 균체, 세포내 및 세포외 불필요한 물질을 제거하고 항생제만을 회수, 정제하는 Down Stream으로 나뉠 수 있다. 따라서 항생제 발효는 좁은 의미에서는 본 발효조에서의 항생제 생합성공정을 가르키지만 넓은 의미에서는 위 전체 공정을 가르키는 말이기도 하다. 따라서 본 소고에서는 항생제 생산을 위한 생물 공정상의 문제점을 3분야로 나누어 제시하고자 한다. 실제로 항생제 공장을 건립하여 항생제 발효를 실시해 왔으며 그것을 좀더 나은 수준으로 개선하고자 꾸준히 노력해 온 당사에서의 경우를 그 예로 보아 문제점을 제시하고자 한다.

본 연구에서는 무인기(UAV)를 활용하여 재난현장을 분석하고 uGIS기법에 의한 처리방안에 대하여 제시한다. 무인기는 군사적인 용도로 개발되면서부터 급속한 민간의 활용으로 확산되면서 소형에서 대형까지 매우 다양한 시스템으로 수 많은 분야에 적용되고 있다. 특히 무인기는 재난재해의 현장에 어떠한 수단보다도 원활하고 신속 정확한 분석과 모니터링을 동시에 수행할 수 있으며, 그 과정을 uGIS기법에 의한 실시간 현장영상의 제공과 현장의 변화관리를 지속가능하게 공중을 나르는 로봇형 공간정보의 한 기술로서 자료의 전송, 보존 및 관리와 운영을 할 수 있다는 새로운 uIT분야의 하일라이트로서 크게 부각되어, 향후에도 무한한 영향력을 발휘할 수 있는 잠재력을 견지할 수 있는 수단으로 기여될 것이다.

Determining the coefficient of weathering(CW) for stone heritage plays very important role in investigation and conservation plan. In most case, CW is obtained from the empirical relation, which use the difference between sonic velocities of fresh and weathered rocks. In this paper, we measured sonic velocities for the samples from Iksan, Geochang, Wonju, Goesan and Chungju of which our stone heritages are made. We first investigate the uncertainty of velocity by portable measurement by comparing it to lab measurement. There were small difference, but we conclude that the difference is not major. However, the velocity of fresh rock differs significantly among samples: ranging from 3200 to 4400m/s. This cause a lot of error in CW estimation if we use typical fresh rock velocity as of 5000m/s. Thus accurate measurement of the velocity of fresh rock is crucial to CW estimation.

This study was conducted to review the feasibility of establishing a joint preservation library centered on the Chungcheongbuk-do Office of Education. To achieve this, a survey and perception survey were conducted. The research results suggest the following: Firstly, the functions of the Chungcheongbuk-do Office of Education joint preservation library should focus on the preservation of valuable materials, the development of Chungcheongbuk-do educational and school-specialized materials, and prioritizing the digitalization of important transferred materials and providing services to the general public. Secondly, when determining the criteria for materials to be transferred in the future, priority should be given to materials that require preservation in their original form and those that need media conversion. Thirdly, when considering the types of materials to be transferred in the future, the operational plan should primarily focus on monographs but also consider other types of materials. Fourthly, regarding ownership rights of materials during the transfer process, it is advisable to establish detailed transfer guidelines, including ownership rights, through discussions between the Chungcheongbuk-do Office of Education and individual libraries via the Joint Preservation Library Operating Committee.

역사의 수레바퀴는 지금도 돌아가고 있다. 이제 그 상황에서도 우리는 이미 우리의 것이 된 근대건축믈을 보존토록 해야 할것이다. 무단히 철거되는 항일의 현장, 신교육의 장소들을 보며 우리는 아쉬움을 느낄 수 밖에 없다. 타의와 자의에 의한 훼손은 이 시간에도 계속되고 있다, "새것만 좋다"는 인식은 또 어떤 건물들을 헐어내 버릴지도 모른다. 이제 우리는 새로운 관심을 이 영역에 쏟아야 할 것이다. 이 연구는 그 작업을 위한 한 단계로 시도되는 것이다.

This study is to adjust the Theory in the Mathematics Education, apply it to learning mathematics and to analyse its effectiveness. The results of the study are summarized as follows. First, because learning mathematics is hierarchical, teachers must make and use a task analysis table classified by units. Second, development age and the retention of mathematics concepts are intimately associated with cognitive development theory. Third, learning mathematics through cognitive processes enhances a student's scholastic achievement. Fourth, students interests and self-confidence can be enhanced through the presentation of both examples and non-examples. We cannot understand the higher-order concepts of mathematics by only its definitions. The only way of understanding such concepts is to have experience through suitable examples.

Deficiencies are present in records management during the production stage of long-term electronic records preservation. As such, this study seeks to address these issues by introducing Cloud On-Nara System (On-Nara Document 2.0) at records management sites and providing various systems and linked services. In particular, the factors that degrade the continuity of long-term preservation in the records management process, from the production to the utilization of electronic records, in On-Nara Document 2.0 were identified, and the causes were analyzed in compliance with ISO 15486-1:2016 and the Public Records Act. As a result, in redesigning the records management procedure, the organization of the records management hub between systems and the conversion of the document preservation format for long-term preservation were proposed. Moreover, the application of consistent production format selection criteria and the reinforcement of the production and management of granular metadata were recorded. These measures were proposed in an effort to reestablish management methods.

We carried out the effect verification of conservation treatment focusing on basement rock of alkali granite at the Yukjonbul (two-pairs of Buddha Triads) carved on rock cliff of Samneung valley in Namsan mountain of Gyeongju. The conservation treatments were used to ethylsilicate-type rock consolidant and epoxy-type resin. It is treatment method that the epoxy-type resin have been applied one time into the exfoliation area, after rock consolidation treatment have been worked for three times. As the result of measuring ultrasonic velocity, P-wave velocity of the exfoliation area was relatively increased after applied the conservation treatments. The ultrasonic velocity of all area was increased as 27.8%. This result has been proved with consolidation effects by consolidant and filler for stone cultural heritages. The treatment method should be worked about three time to consolidate sufficiently for rocks.
