Safety inspections of outdoor advertisements are conducted to determine the aging status, specifications, and compliance with design documents. Regular inspections are conducted on outdoor advertisements from a safety perspective, as they not only undermine the aesthetic elements of the city but also could cause falls on roads or pedestrian paths. However, the current safety inspection methods are at risk of various accidents during the inspection advertisements on the outer wall of the building. And it is difficult to conduct in-depth inspections on them if they are fixed to the elevation of the building. Furthermore, there also is a risk of safety accidents, such as advertising structures falling onto a pedestrian path. Therefore, this paper aims to enhance the safety inspection system of outdoor advertisements using drones. This paper also intends to propose measures for facility inspection history management such as safety inspection cycle, maintenance, and removal of signboards.

As a national library, the National Library of Korea is responsible for collection, provision, and preservation of national knowledge, information, and cultural heritage. This study aims to develop performance indicators as a rational tool to improve management of the National Library of Korea for its continuous growth and development. The performance indicators are based on the BSC(Balanced Scorecard), which is useful for linking the organization's strategies in response to changes in the library environment with performance measurement. As a result, 4 BSC-based perspectives (① Resources, Access, Infrastructure Perspective, ② Usage Perspective, ③ Efficiency Perspective, ④ Potential and Growth Perspective), 19 key success factors, and 71 performance indicators were developed for the National Library of Korea. Also, differences in perception of performance indicators by ranks and job duties at the National Library of Korea were analyzed.

The purpose of this study is to analyze the status of e-books usage in small university library and to suggest implications for e-book management policies. To do that, a survey was conducted with students in a local small university, and the valid responses of 259 people were analyzed. As a result of the analysis, the preference of paper books (71%) was higher than that of e-books (12%). However, satisfaction with e-books (45.6%) was higher than that of paper books (27.9%) if they had experience using e-books. In addition, satisfaction was highest when using e-books for general reading, and it was found that the use device preferred to use a tablet. Based on the results of this study, we proposed some suggestions; 1) establishment of e-books service policy and promotion plan, 2) use of e-books dedicated devices and development of user-friendly e-books using environment, 3) providing various topics of e-books, 4) formation of an association for joint use of e-books between small library universities.

National libraries have a responsibility to intensively develop, preserve, and provide national collections, which are the knowledge and cultural heritage of a country. In particular, in order to achieve 'advancing the base for access and preservation of national knowledge resources' among the four goals to fulfill the mission of the National Library of Korea, it is necessary to strengthen the national knowledge resources by expanding the external scope to not only domestic materials but also foreign materials. In other words, The National Knowledge Information Center collects the latest and retroactive data produced in Korea, as well as high-quality academic materials produced, distributed, and preserved in foreign countries as well as materials related to Korea. This study drew implications by investigating and analyzing the status of foreign collection and services of national libraries in developed countries. Based on this, the purpose of this study is to compare and evaluate the current level of collection of foreign collections of the National Library of Korea, and then present a strategy to secure high-quality academic and foreign materials related to Korea.

The purpose of this study is to transform the sub-categorization terms of the National Science and Technology Standards Classification System into technical keywords by applying a machine learning algorithm. For this purpose, AttentionMeSH was used as a learning algorithm suitable for topic word recommendation. For source data, four-year research status files from 2017 to 2020, refined by the Korea Institute of Science and Technology Planning and Evaluation, were used. For learning, four attributes that well express the research content were used: task name, research goal, research abstract, and expected effect. As a result, it was confirmed that the result of MiF 0.6377 was derived when the threshold was 0.5. In order to utilize machine learning in actual work in the future and to secure technical keywords, it is expected that it will be necessary to establish a term management system and secure data of various attributes.

In this study, the appraisal in record continuum theory is analyzed in conjunction with the appraisal in life cycle model. In order to understand the more fundamental implications of appraisal in electronic record environment, it is essential to analyze the appraisal inherent in record continuum theory. Record continuum theory can provide a theoretical basis for appraisal in electronic record environment in that it is a theoretical system in opposition of the appraisal based on life cycle model and dualistic records management system resulting from it. In particular, considering that the appraisal is a purposive act of seeking the meaning of records, the reinterpretation of the concept and meaning of records intended in record continuum theory enables us to derive the different appraisal logics than before. Therefore In this study, based on comparison with the appraisal based on life cycle model and the new record concept presented in record continuum, the appraisal in record continuum theory is analyzed focusing on three aspects.

In order to prevent slope disasters caused by rainfall, it is very important to quickly exclude rainfall. In Korea, horizontal drainage holes with excellent economic feasibility and construction performance are generally applied as a method to lower the underground water level. However, horizontal drainage holes constructed on the site are often uniformly constructed regardless of the presence or absence of other water or ground conditions, and it is often difficult to expect drainage performance of horizontal drainage holes due to poor maintenance. In this study, an artificial ground was created using model construction and horizontal drainage experiments were conducted to measure the amount of horizontal drainage drain in a certain amount of control area 0%, 25%, 50%, 75%, and an evaluation table (draft) that can quantitatively evaluate horizontal drainage based on measurements and design documents is proposed as basic data.

기후변화에 따른 기온과 강수량 등 기상조건의 변화로 인하여 기상·자연재해뿐만 아니라 작물의 수확량 감소, 병해충 및 잡초 발생의 증가, 흙과 물의 부족, 재배 적지의 변화와 같은 농업인프라 또한 기후변화의 피해가 발생하고 있다. 농업수자원 측면에서, 농어촌용수는 자연적으로 내리는 강우를 직접 작물성장에 사용하기 때문에 기후변화에 특히 민감하다. 또한 기온의 변화는 농업용 저수지의 증발량 및 유입량의 변화를 일으키며 이러한 변화는 곧 저수위 및 저수량의 변화를 유발하여 농업·농촌 수자원 관리의 어려움으로 이어질 것으로 판단된다. 이에 따라, 기후변화에 따라 예상되는 대규모 자연재해를 대비하고 기후변화에 효율적으로 대처하기 위해서는 체계적이고 과학적인 기상·기후 정보의 활용이 중요하며 기후변화로 인한 농업 기상재해 최소화를 위해서는 다양한 기후변화 시나리오를 활용하여 미래 기상·기후의 변화에 대한 경향성 분석 및 예측을 통한 영향 평가가 필요하다. 본 연구는 전국 농어촌용수구역 517개 용수구역 중 접경·도시·도서지역을 제외한 511개 용수구역을 대상으로 증발산량 산정이 가능한 RCP 8.5 기후변화 시나리오 9개를 지역별로 상대적인 기후사상의 크기와 빈도 및 강도 정량적으로 평가할 수 있는 STARDEX 극한지수를 적용하여 시나리오의 미래 기상전망을 실시하였다. 기상전망 결과를 이용하여 Kendall-Tau 검정을 통해 시나리오의 순위를 적용하여 각 시나리오의 미래기후변화의 상대적인 정도를 평가하였고, 9개의 기후변화 시나리오를 DIROM(Daily Irrigation Reservoir Operation Model) 모형에 적용하여 기후변화 시나리오의 높은 불확실성을 고려한 미래 농어촌용수구역의 농어촌용수 필요수량 변화를 지역적으로 분석하고 미래 농어촌용수량의 최대·최소 변화 범위를 제시하였다.
