The government continues to announce measures to revitalize smart construction technology based on BIM for productivity innovation in the construction industry. In the design phase, the goal is design automation and optimization by converging BIM Data and other advanced technologies. Accordingly, in the basic design of the Namhae Seomyeon-Yeosu Sindeok National Road Construction Project, a domestic undersea tunnel project, BIM-based design was carried out by developing tunnel design automation technology using 3D spatial information according to the tunnel design process. In order to derive the optimal alignment, more than 10,000 alignment cases were generated in 36hr using the generative design technique and a quantitative evaluation of the objective functions defined by the designer was performed. AI-based ground classification and 3D Geo Model were established to evaluate the economic feasibility and stability of the optimal alignment. AI-based ground classification has improved its precision by performing about 30 types of ground classification per borehole, and in the case of the 3D Geo Model, its utilization can be expected in that it can accumulate ground data added during construction. In the case of 3D blasting design, the optimal charge weight was derived in 5 minutes by reviewing all security objects on the project range on Dynamo, and the design result was visualized in 3D space for intuitive and convenient construction management so that it could be used directly during construction.

The purpose of this study is to extract and analyze ecological citizenship elements in the middle school home economics textbook used in the 2015 national curriculum for the introduction of ecological transformation education in the 2022 national curriculum. As a result of the analysis, the content analysis of the ecological citizenship factor was validated by six experts who are incumbent middle school home economics teachers, and the S-CVI value was 0.97, ensuring the validity of the ecological citizenship factor analysis. The results of analyzing 242 ecological citizenship factors extracted from home economics textbooks are as follows. According to the content area of the 2015 national home economics curriculum, the 'human development and family' area had the highest presence of ecological citizenship factors followed by the 'resource management and self-reliance' area and the 'home life and safety' area. Among the categories of ecological citizenship factors, 'value⋅attitude' was the most frequent, followed by 'process⋅function' and 'knowledge⋅understanding'. For each textbook composition system, ecological citizenship elements were extracted in the order of pictures, text, activities, and supplementary materials. There was a significant variation in the number of ecological citizenship factors among publishers, indicating the importance of the textbook writers' perception, interpretation, and direction of writing. Based on these analysis results, ecological citizenship teaching and learning activities applicable to home economics education were presented. This study highlights the potential for practicing ecological citizenship education in line with the new orientation of the curriculum on ecological transformation education through home economics education. Furthermore, it provides valuable baseline data for the development and implementation of textbooks for the 2022 national curriculum.

Medvedev administration has adopted new foreign policy line because of Obama administration's 'Reset' policy and Global economic crisis. The objectives of Medvedev's new foreign policy are the creation of a favorable external environment and the efficient use of external resources for Russia's economic modernization. To achieve these goals, Medvedev's government fleshed out such specific action plans as the avoidance of conflicts with other powers, the prevention of conflicts around Russia's borders, the activation of capital investment, and the introduction of advanced technology from the outside. This foreign policy line takes shape in the building of a foundation for strategic cooperation with the United States, the preparation for 'Modernization Alliance' with Europe, the management of cooperation and conflict with China and Japan, and the introduction of a dual strategy of strategic stability and economic integration in relations with post-soviet states. In Russia's new foreign policy line the strengthening of relations with the United States and Europe acquires highest priority. However, this does not mean a return to a 'pro-Western liberal line' in the early 1990s. The ultimate goal of Russia's 'modernization' program still lies in the rebuilding of a powerful Russia in accordance with the multipolar world order that was Putin administration's foreign policy line. In this context, foreign policy change under Medvedev administration could be defined as a 'program change at international level' that signifies a change in the means to achieve goals without changing them.

World Heritage is a very important heritage that is worth protecting and handing down to future generations. In Korea, which has a long history and culture of 5,000 years, Seowon is a great advantage in that it can develop tangible and intangible Neo-Confucian ideas shared in China and East Asia, and preserve and experience them as a unique cultural resource of Korea until the present day. In order to encourage the direct experience of this long-standing cultural heritage, the government supports the national treasury and seeks to expand the demand for tourism. Accordingly, in this study, an analysis was conducted on program satisfaction, participation, and activation plans. As a result, it was found that value to see and value to experience must coexist in order for our world heritage, which requires comprehensive and continuous management and operation, and lacks accessibility, to become a tourist attraction. Also, for this purpose, promotion and development of differentiated tourism experience contents should be carried out first.

As the effective use and strong protection of an organization's information resources are recognized as a condition for the growth of an organization, they are increasing technological and policy investments in IS(information security). However, information exposure can occur from external invasions such as hacking and incidents related to misuse and abuse by insiders. This study proposes a mechanism that considers the organizational environment and individual characteristics from the viewpoint of promoting employees' IS participation activities. In other words, the study presents the complex effects of organizational environmental factors (ethical leadership, IS collaborative communication) and personal factors (person-organization fit) on organization trust and IS voice behavior. We surveyed office workers who asked for IS-related business activities and tested hypotheses using 422 samples. As a result, ethical leadership influenced organization trust through collaborative communication, and organization trust strengthened IS voice behavior by having an interaction effect with person-organization fit. This study suggests direction for establishing an organizational environment for promoting IS-related activities by office workers, so it provides practical implications for organizations with goals related to internal information exposure control.

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.
