The National Library of Korea (Sejong), which was launched in December 2013, has been in the spotlight as a specialized library for Korean policy information and as a Sejong city complex cultural facility. Nevertheless, the essential identity, organizational status, division of affairs and core competencies, policy information collection, and services of the NLK (Sejong) are weak and inadequate. Therefore, this study developed a job model for establishing an essential identity and providing high-quality policy information services nationwide and suggested a strategic organizational reorganization plan. The job model was proposed as a total of 110 by adding 38 to the existing 72. Based on this job model, the short-term reorganization model (2023-2024) changed the grade of the library director from the current grade 4 (administrative officer) to Senior Executive, and the grade of the director by division from grade 5 (secretary) to grade 4. The sub-organization has expanded the current 3 divisions (planning management, policy information, and service use) to 4 divisions (planning administration, library collection and development, policy information service, and public service and culture, with a total of 51 personnel. In the mid-to-long-term model (2025-2032), the sub-organization was expanded to 4 divisions and 1 office (planning administration, library collection and development, policy information service, public service and culture, and policy information research), and presented a total of 61 personnel. To this end, it is necessary to persuade stakeholders with the argument of advocating the Korean policy information center, which is a macro-strategic goal, and focus all capabilities on strategic reorganization and revision of 「Decree on the Organization of the Ministry of Culture, Sports and Tourism」.

As the secondary battery market expands, the process of producing laterite ore using the rotary kiln and electric furnace method is expanding worldwide. As ESG management expands, the management of air pollutants such as nitrogen oxides in exhaust gases is strengthened. The rotary kiln, one of the main facilities of the pyrometallurgy process, is a facility for drying and preliminary reduction of ore, and it generate nitrogen oxides, thus prediction of nitrogen oxide is important. In this study, LSTM for regression prediction and LightGBM for classification prediction were used to predict and then model optimization was performed using AutoML. When applying LSTM, the predicted value after 5 minutes was 0.86, MAE 5.13ppm, and after 40 minutes, the predicted value was 0.38 and MAE 10.84ppm. As a result of applying LightGBM for classification prediction, the test accuracy rose from 0.75 after 5 minutes to 0.61 after 40 minutes, to a level that can be used for actual operation, and as a result of model optimization through AutoML, the accuracy of the prediction after 5 minutes improved from 0.75 to 0.80 and from 0.61 to 0.70. Through this study, nitrogen oxide prediction values can be applied to actual operations to contribute to compliance with air pollutant emission regulations and ESG management.

The purpose of this study was to investigate the effects of Adapted Physical Education Majors' perceived teacher competencies on the emotion reaction towards challenging behaviors of students with disabilities. In order to achieve the object of the study, the data collected from 413 sophomores, juniors, and seniors currently studying adapted physical education in schools located in Seoul, Gyeonggi, Gyeongnam, and Gyeongbuk, where they offer department of adapted physical education, was analyzed. As a measuring tool, Kwon (2008) and Han (2011) questionnaire for adapted physical education educators' perceived teacher competency and Oh, Seo & Kozub's (2010) questionnaire on the emotion reaction towards challenging behaviors of students with disabilities were revised, modified, and reconstructed. Data was processed using SPSS 21.0, and the exploratory factor analysis, reliability verification, difference verification, and multiple regression analysis were performed. The results are as follows. First, in terms of the analysis of emotion reaction based on demographic characteristics (sex, grade, disability in the family, friends with disabilities), sex, grade, and friends with disabilities displayed statistically significant difference on emotion reactions. Second, in terms of the effects of adapted physical education educators' perceived teacher competencies on the emotion reactions on towards challenging behaviors of students with disabilities, the parental education and the special activities of adapted physical education among the sub-factors of perceived teacher competencies affected significantly on emotion reactions, whereas the common knowledge on adapted physical education, curriculum lesson, and education knowledge by disability did not affect significantly on emotion reactions.

The purpose of this case study was to construct a social context-based musical play program for children with high-functioning Autism Spectrum disorder (ASD) and to examine its applicability in improving the social skills of the children. The participants were a group of three children with high-functioning ASD with an average age of 9 years. The children participated as a group in 40-minute sessions that were implemented twice a week for 8 weeks. The children's social communication behaviors were observed during the sessions and analyzed in terms of sharing and exchanging their ideas and voluntarily interacting with peers and an adult (i.e., the researcher). The Social Skills Rating System (SSRS) was completed by the teachers of participants before and after the intervention. For all three participants, the occurrence of behaviors to exchange their ideas with peers and voluntarily interacting with an adult increased following the intervention. However, there were individual differences between the participants in terms of changes in each target behavior depending on their level of language and social skill development. These results suggest that social context-based musical play program may produce positive changes in voluntary communication with peers and play a significant role in expanding the scope of interventions that target the social communication of children with ASD.

최근 우리나라에서 농업용수의 다원적 기능에 대한 공감대가 형성되고 작물생육에 필요한 관개용수로만 인식되던 농업용수의 개념이 농촌생활환경개선을 포함하는 다양한 지역용수로의 포괄적 개념으로 전환되고 있다. 농업용수는 식량생산 이외의 효용을 위한 다원적 기능을 가지며 농촌지역의 각종 생산활동과 생활조건의 유지개선을 위한 농업용수의 다원적 기능에 관한 관심이 증가하는 추세이다. 농업용수에서 발생하는 회귀수는 유역의 용수공급계획, 하천 유황의 예측, 관개용수 사용량 결정, 하천 건전화 방지, 수생생태계 보호 및 생물 다양성 확보 등 농업용수의 효율적 사용 및 환경생태유지를 위해 매우 중요한 역할을 하고 있다. 농업용수 회귀수량은 농업용수 중 하천으로 회귀하는 수량을 의미한다. 본류의 생태 유량 확보에 농업용수 회귀 수량이 기여하고 있으며 본류 하천의 환경 보전 기능을 하고 있다. 또한, 수생태계 보호 및 생물 다양성 확보 등 환경 생태 유지에 매우 중요한 역할을 하고 있다. 하지만 농업용수 회귀수량이 하천 수생태에 미치는 영향 분석 연구는 미흡한 실정이다. 따라서 본 연구의 목적은 대사 저수지 유역을 대상으로 농업용수 회귀 수량이 하류 하천 수생태에 미치는 영향을 정량적으로 평가하고자 한다. 본 연구에서는 회귀 수량은 관개용수량, 배수량, 침투량, 담수심 등 물수지 항목을 논물수지 모형에 적용하여 산정하였으며, 하류 하천의 생태유량 산정을 위해 대사저수지 하류에 위치한 생물측정망 자료를 통해 대표 어종을 선정하였다. PHABSIM 모형을 이용해 모의 대상 지역 특성 자료 및 인근 소하천 생물측정망 자료를 바탕으로 HSI 기반 대표 어종 서식처 환경에서 최적 생태유량을 산정하였다. 이를 통해 추정된 농업용수 회귀 수량에 따른 필요 유량이 어류 서식환경에 미치는 영향을 평가하였다. 본 연구 결과 대사저수지 하류 하천에서 농업용수 회귀수량이 차지하고 있는 기여도 큰 것으로 분석되었으며, 최적 생태유량과 비교한 결과 농업용수 회귀수량이 수생태(어류)에 미치는 영향이 큰 것으로 나타났다. 따라서 농업용수 회귀수량은 하류 하천의 하천유지수량뿐만 아니라 하천 환경생태유지에도 매우 중요한 역할을 하고 있음을 알 수 있다.

The purpose of all public libraries is to provide knowledge and information services for the intellectual and reading activities of local residents, program services that provide opportunities for cultural enjoyment and lifelong learning, and third-party spaces and facilities that contribute to the development of the community. To this end, social needs must be reflected in a timely manner with the establishment of a sound infrastructure as a prerequisite. This study analyzed the current status centered on key indicators of the public libraries in Daegu City and presented policy issues that need to be improved through a survey. The key indicators in Daegu City, compared to the national average, were not only significantly weak for the 3rd largest city but also showed considerable variation among local governments. While Daegu citizens valued public libraries in their daily lives, the dissatisfaction rate was high in the order of transportation inconvenience, lack of necessary materials and desired programs, and various regulations. Therefore, Daegu City should focus on increasing the acquisition budget, strengthening the development of new book collections, expanding the number of librarians, expanding the construction of public libraries to address service disparities among local governments, improving accessibility, and addressing factors that hinder usage. In addition, with the establishment and operation of the Daegu Library in 2024, efforts should be made to establish an operational system for public libraries, expand the scope through collaborative partnerships with other knowledge and cultural institutions, and enhance knowledge and cultural services for the Daegu citizen.

The purpose of this study is to discover the occupational identity by examining the narrative of the life of a vocational training teacher with self-esteem in programming fields. The following six types of occupational identity were found: 'a positive image of a vocational training teacher(fits oneself)', 'I feel proud of myself while doing vocational training activities.', 'a teacher who continues to develop him/herself as an expert in the subject class', 'a teacher who immerses him/herself as an expert on student change and growth', 'a teacher engaged in leading activities to create opportunities for vocational training', and 'a teacher of continuous pursuit'. This study has significance in exploring the structure of occupational identity recognition and experience of its formation of a self-esteemed vocational training teacher in programming fields, which have not been studied.

The present study examines the dialectic tensions arising within the ICT-mediated labor culture between the dominant power of conglomerates and the precarious labor subjects in the labor practices, as smartphones and tablet PCs have grown in popularity. The present study explores how much young precarious workers named 'Cheongyeon Alba' (young precariat in S Korea) suffers from continually precarious job positions as temporary staff or contract workers, being trapped at the bottom of the pay scale, and also being electronically connected to the workplace in a seamless way. Concretely, this study investigates how the mobile phone becomes deeply entangled with the 'precarious' labor culture in the metropolitan city of Seoul. The mobile precariat has been in a disadvantaged position, in terms not only of the moral issue of exploitation in business but also of social injustice. Labor exploitation of young workers has been reinforced by the mobile labor culture, in which they are remotely monitored by live surveillance mobile apps, and mobile instant messaging from a boss can intrude incessantly into their private life. This study depicts the extension of the business's surveillant power by mobilizing the mobile phone in the working practices.

Laboratory compressive test was conducted on 6 different types of rock in order to investigate the characteristic of critical strain under uniaxial and triaxial stress condition. The results of uniaxial compressive test mostly ranged within 1~100MPa, the critical strain was also located between 0.1~1.0%. Therefore the results distributed within the upper and lower boundary proposed by Sakurai (1982). And the failure/critical strain ratio (${\varepsilon}_f/{\varepsilon}_0$) showed between 1.0~1.8 value depending on the uniaxial compressive strength. The results of critical strain by triaxial compressive test showed below 0.8% value for all test, the M value calculated from uniaxial and triaxial compressive test results ranged 1.0~8.0 for most of rock specimens. It is concluded that failure strain (${\varepsilon}_{f3}$) of rock mass, which is in triaxial stress condition is larger than the results of uniaxial stress condition (${\varepsilon}_{f1}$) by 1.0~8.0 times and value showed 1.0~1.8 larger value than critical strain (${\varepsilon}_{01}$). Therefore it is a conservative way for rock tunnel to use critical strain (${\varepsilon}_{01}$) calculated from a uniaxial compressive strength on tunnel displacement monitoring.
