This study investigated the impact of utility value intervention on 5th and 6th grade elementary students’ mathematics interest, considering their self-efficacy beliefs. Mathematics interest was measured in terms of situational interest and willingness to participate in the class. Two intervention strategies- self-generating writing and evaluative writing(where utility value information was directly provided) -were compared to a control group. A total of 375 students participated in the study, and data from 371 students were analyzed. Multiple regression analysis was conducted controlling for gender, personal interest, and writing self-efficacy. The results showed that the utility value intervention positively impacted mathematics interest, with both self-generating writing and evaluative writing showing significant effects on situational interest and willingness to participate, compared to the control group. Furthermore, the impact of the utility value intervention on situational interest was moderated by mathematics self-efficacy levels. It was particularly effective in increasing mathematics interest for students with high math self-efficacy beliefs. However, for students with low math self-efficacy, neither intervention strategies showed significant effects. These findings imply that additional or different types of interventions may be necessary to effectively enhance mathematics interest for students with low math self-efficacy. Educational Impact and Implications : This study highlights the importance of providing opportunities for students to develop their perceptions of the usefulness and real-world applications of mathematics, thereby enhancing their interest. Furthermore, considering the differential effects based on mathematics self-efficacy levels, teachers should carefully plan and implement utility value interventions, taking into account students’ individual characteristics, such as self-efficacy or perceived competence. By doing so, educators can develop students’ interest in mathematics and cater to the specific needs of students with varying levels of expectancy beliefs.

This study case is a new 624 household apartment construction project located in Sinhyeon 1 district, Gwangju-si, Gyeonggi-do, and it took 15 years from the time of land purchase to moving in, of which 13 years were taken to resolve legal restrictions. Despite the fact that it was a project site with a good location, even after the start of construction, the real estate sales management task was not properly performed internally by the developer, so the sales rate was low. It is a project that has been able to successfully complete the project by normalizing the sales management through cooperation with the construction company. The purpose of this review is to examine the legal restrictions that may occur in the case of large-scale apartment development projects in advance and to identify ex-post solutions to the sales management, which is one of the operational risks that may occur in the course of the development project. and On the similar apartment development projects, this paper intends to present meaningful lessons for proactive prevention and follow-up management of various practical difficulties in the real estate development project. 본 연구 사례는 경기도 광주시 신현1지구 소재 624세대 아파트 신축사업으로서, 토지 매입 시부터 입주까지 무려 15년이 걸렸고, 그 중 13년은 법적 제한 사항 해소를 위해 소요된 사업이다. 양호한 입지성을 갖춘 사업지였음에도 불구하고, 착공 이후에도 시행사 내부적으로 분양 관리 업무를 제대로 수행하지 못해 분양률 저조를 경험하였고, 추후 시공사 등의 협력으로 분양 관리 업무를 정상화하여 성공적으로 사업을 마무리할 수 있게 된 프로젝트이다. 대규모 아파트 개발사업 시 발생할 수 있는 법적 제한 사항들에 대한 사전적 검토와 개발사업 진행 과정에서 발생 할 수 있는 운영상 위험요소들 중 하나인 분양 관리에 대한 사후적 해결방안을 파악하고자 하며, 향후 유사한 아파트 개발사업에서 제반 실무적 난제들에 대한 사전적 예방과 사후적 관리를 위한 유의미한 교훈을 제시하고자 한다.

This study intends to explore the scope of the recognized equity capital of developer in real estate project finance loan screening. The factors which can be recognized as equity capital are categorized into 24 factors with 3 upper categories and 6 mid categories. In order to develop the importance weight of factors, AHP and Fuzzy methodologies are implemented based on survey analysis by experts in financial institutions. Research findings indicate that the land cost, evacuation cost, and real estate acquisition tax as land-related direct costs, and the design cost, traffic impact assessment cost, underground safety impact assessment cost, boundary surveying cost, and geological survey cost as the construction permit-related costs are higher than any others. On the other hand, the supplementary costs related to the operation of the developer show very low importance weight. Accordingly, the hierarchy of factors for equity capital should be clearly developed in order to minimize any dispute and prevent non-performing loans to real estate project finance.

In this paper, a commercial multibody dynamics program ADAMS was utilized to investigate the model for the multi-joint boom conflicts. In this process, CATIA, ANSYS and ADAMS were used to develop the simulation. The addition of ADAMS made the system more accurate and improved precision of the system. In brief, the 3D CAD model of the structure was initially developed via CATIA. After this, the CATIA models were exported to ANSYS for creating flexible-body modeling by using formatted file. Subsequently, with ADAMS, the flexible body model was directly imported from ANSYS which performed the analyses of the dynamic collision of the nozzle boom conflicts. This contained the information regarding geometry and model shapes of the flexible body. Using ADAMS/Durability, it was possible to determine the strain energy for the nozzle configuration by crashing the contact structure that was created. Via this procedure, the acquired simulation analysis of nozzle showed interestingly good results with respect to the objectives of the study

In this research, the forward and inverse kinematics equations for demolition fire vehicle with 6-DOF were developed. This was done through the development of an interface that allows co-simulation using MATHEMATICA and ADAMS. The implementation of this project was done entirely in MATHEMATICA by calculating the kinematics equations to demonstrate the usefulness of this product. The forward and inverse kinematics of the demolition fire vehicle represents the position and orientation of the end-effector as any desired location. This research was particularly conducted using the simulator, and it showed good approximation results in terms of solving a reaching task problem.
