This study analyzed the gap between users' perception and staff expectations on users' perceptions about dimensions of library service quality(library staff, service supports. materials and resources, and facilities and equipments), service value, user satisfaction, royalty. using newly developed model. Six hundred-fourteen users and one hundred staff members or the National Libra of Korea were participated in the survey using questionnaires. Users evaluated service quality lower but evaluated service value, satisfaction. and loyalty higher In terms of showing complaining behaviors, users were less than staffs expected. Model analysis for users and staff3 showed that service value and general satisfaction influenced on complaining behavior and loyalty. For users. only the dimension of library staff influenced significantly on the service value, satisfaction, complaining behavior, and loyalty. None of the other dimensions of the service qualify showed significant relationship to them in the case of staff expectation.

ARS (Automatic Response Systems) based on VUI (Voice User Interface) and TTI (Touch Tone Interface) are one of the most widely used communication systems. Despite common usages, however, inconvenience of ARS is continually pointed out. This may stem from lack of human-centered studies aside from technological development. In this paper, we provide guidelines for designing ARS by analyzing hindrance factors of usability of ARS menu structure. We had selected two call-centers using ARS, and carried out an experimental study where subjects performed the task of "returning books." After that, they completed questionnaires and interviews. We identified four problems: the complex menu structure, lack of representativeness on the menu name, users' awareness of location, and a difficulty to move among menus. And we partially discussed the ways of avoiding the problems.

Recently, big data, a major technology in the IT field, has been expanding into various industrial sectors and research on how to utilize it is actively underway. In most Internet industries, user reviews help users make decisions about purchasing products. However, the process of screening positive, negative and helpful reviews from vast product reviews requires a lot of time in determining product purchases. Therefore, this paper designs and implements a system that analyzes and aggregates keywords using LDA, a big data analysis technology, to provide meaningful information to users. For the extraction of document topics, in this study, the domestic book industry is crawling data into domains, and big data analysis is conducted. This helps buyers by providing comprehensive information on products based on user review topics and appraisal words, and furthermore, the product's outlook can be identified through the review status analysis.

This study was implemented to verify the validity and effectiveness of the current evaluation indicators by analyzing the content and result of the current survey for evaluating a small library, based on the achievement rate of each index. To this end, questions, included in evaluation indices for the small library were reviewed, and survey data from a total of 19,476 libraries during the past 3 years from 2018 to 2020 were investigated to analyze the evaluation scores, differences and achievement rates of each item. It was proposed to delete or add some indicators of the current evaluation category, and to raise supplementally the need for qualitative assesment. Based on the research results, the following implications are suggested. First of all, the evaluation of small libraries should focus on the quality of the services they provide rather than the library environment. Second, demonstrable systematic indicators should be designed and then clearly explained to resolve the ambiguity of the terms used. Third, for better analysis, it is necessary to distinguish evaluation items between public and private small libraries and the assessment process should be done by the local government. Lastly, qualitative evaluation items that can measure users' satisfaction should be added.

The purpose of this study was to designed the structure and elements of metadata that can manage and share research data produced in the food composition database. In order to derive metadata elements, mapping crosswalk was performed on 5 metadata such as DCAT, DataCite metadata schema 4.4, TTAK.KO-10.0976, AgMES, and FoodData Central. As a result of the study, the top 15 elements of the 'Resource information' metadata were derived, and 7 mendatory, 3 recommended and 5 optional elements, and the 'Composition analysis' metadata included 8 mendatory, 3 recommended and 1 optional element were derived to describe food composition research data, respectively. The derived metadata elements will be used as an item for systematic management of food composition data and can be used as basic data for sharing with domestic and international food composition databases.

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.

최근 기후변화로 인해 지역 및 시기별로 강수량이 편중되면서 가뭄(0.72회/년) 등 물 관련 재해가 빈번하게 발생하고 있으며, 가뭄의 강도 또한 심화되는 추세이다. 본 연구대상 지역인 태안군과 괴산군의 경우 기후변화 시나리오(RCP 4.5)를 적용, 미래(~2100년) 기상조건에 대하여 기존 농업용 저수지의 용수공급능력을 평가한 결과, 가뭄대응(내한) 능력이 감소하는 것으로 분석되었다. 한편, 농업가뭄의 경우 주로 영농기에 발생하여 장마가 시작되면서 해소되었으나, 최근 기후변화로 인해 지속기간이 점차 증가하여 가뭄피해가 매년 반복되고 있다. 그러나, 현재까지 추진된 가뭄대책의 경우 관정개발, 저수지 준설 등 단기·사후처방 중심의 대책이 마련되어 지속적인 재해관리와 예방에 많은 어려움을 겪고 있다. 이에 본 연구에서는 지역 맞춤형 가뭄대응 종합대책을 마련하여 기후 변화대비 안정적인 영농기반을 구축하고자 하였다. 기존시설 개선, 수요관리 등 최근 정부정책 방향과 재원조달 방안을 고려, 법적근거(농어촌정비법 등)에 의한 실현 가능한 사업계획을 수립하는 한편, 다목적 농촌용수 개발, 용수이용체계 재편 등 사업유형을 구분한 후 단계별(장·단기) 가뭄대책을 마련하였다. 가뭄대책 수립 시 한국농어촌공사에서 개발한 '수리수문 설계 시스템(K-HAS)'을 이용하여 용수 수요량을 산정하였고, 기존 수리시설물별 물 수지 분석을 통해 여유수량이 확보된 수원을 최대한 활용코자 하였다. 저수지 개발 등 신규 수자원 확보가 용이한 내륙·산간지역의 경우 중·대규모 저수지(유효저수량 1백만m³, 유역면적 200ha이상) 개발계획을 수립하는 한편 지역특성(형상, 표고차 등), 개발여건 및 경제성 등을 고려하여, 적정 개발범위(수혜면적 20ha이상)을 설정하였다. 한편, 신규 수자원개발이 어려운 도서·해안지역의 경우 용수 재이용(회귀수 활용) 및 담수호 내 염해방지시설을 도입하는 등 지역 맞춤형 가뭄대책을 수립하였다. 본 연구에서 제시한 단계별(장·단기) 가뭄대책이 차질없이 시행될 경우 기후변화 대비 안정적인 농업용수공급이 가능하고, 상습가뭄 발생(물 부족) 지역에 대하여 효율적이고 합리적인 물(수요·공급)관리가 가능할 것으로 기대된다.

The purpose of this study is to identify how teacher librarians perceive the importance of each job and the expected job of other teachers and students, and to obtain basic information on their job recognition and to derive their jobs to be improved. To this end, after modifying the 25 jobs selected by Lim Jeong-hoon et al.(2021), 210 librarian teachers were measured for their own importance by job, the expected importance of other teachers and students, and the level of evaluation of their own performance ability. As a result of the analysis, teacher librarians recognized 'reading education and literacy education' as the most important, but recognized 'library event' as the most important task expected of other teachers and students, and recognized that 'library usage guidance' was the most outstanding. In addition, there were nine jobs that needed to be improved.
