The purpose of this study was to understand the experience of persons with developmental disabilities participating in the Personalized Support Services. For case study, we conducted in-depth interviews with the persons with developmental disabilities and with the active supporters for them who were using the community welfare centers for the disabled. Through this, we have come up with three core categories: 'coming out into the community', 'experimenting with various choices in life', and 'living a subjective life'. This suggests the followings; First, it can be seen that persons with developmental disabilities who have limited communication and self-determination should be allowed to participate in the service through the participation process, and active support for the parties is needed in the process. Second, it is necessary to plan and support for them, centering on the parties, away from institution-centered services. Third, sufficient budget support should be provided for the self-determination, selection and control of the parties. Fourth, we should be able to enjoy everyday life by participating together in the local community, and change the perception of local residents to participate in the community. Fifth, continuous support is needed rather than temporary support. Finally it will be needed for us to listen to the voices of both parties and to represent their rights with all our efforts.

Recently, the paradigm of road policy has been focused on user safety. Recently, the number of road facility improvement project has been continuously increased but the economic feasibility (B/C ratio) is insufficient. Therefore, it is necessary to select a reasonable road improvement project through accurate and objective analysis of the road safety evaluation. In this study, to develop a new road safety evaluation method, data were collected based on the current road safety evaluation method for 75 routes including national roads and provincial ones. Based on the collected data, problems were analyzed and utilized as the basic factors of the new road safety evaluation method. Therefore, in this study, traffic accidents were reflected as a general evaluation item by weighing to solve these problems, and the evaluation items were added from experiences and ideas of the local public officials. For each evaluation item, a reasonable weight was determined through AHP (Analytic Hierarchy Process) questionnaire evaluation with highway experts. In addition, the safety index was determined based on the evaluation criteria for each evaluation item. The criteria for evaluating the danger zone are determined by the overall safety index. Finally, the criteria for selection of road improvement projects based on the overall risk level were derived.

This paper examines the contents and meaning of the education reform theory among the social reform theory of Wie Baek-gyu(1727~1798), a representative Confucian scholar of Honam in the 18th century, and suggests the moral educational implications of his educational reform theory. Wie Baek-gyu, who lived through the Yeongjo and Jeongjo eras, diagnosed the contradictions and problems of society at that time as the absence of morality. And emphasized the reform of school education as a center of ways to overcome social disruption. The educational reform theory he envisioned was to systematize the process from child education to higher education centered on the system reorganization of the school, and to formulate school education in conjunction with the selection of talent. He emphasized the cultivation and practice of moral character in the course of admission and curriculum of the school, and suggested a system that reflects the opinions of the local people in the admission process, thereby establishing the school as the center of the local society. His educational reform theory, which embodies the school system based on moral education and further shapes the school system and educational contents as the center of edification and recruitment of talented people, is a big indication of the curriculum of the current moral curriculum that emphasizes the cultivation and practice of inner morality based on personality education. In this paper, I summarized and reviewed the general contents of his perception of the times and social reform theory, the diagnosis of the educational reality that is the basis of his educational reform theory, and the specific contents of the education reform theory. Based on this, I presented the meaning to the current moral and curriculum.

Street trees improve the cityscape and air quality, reduce heat islands, and create wildlife habitats. Hence, they are essential parts of a city's green infrastructure. Therefore, several trees that are well adapted to the urban environment were planted. However, this caused the problem of simple trees being planted around the world. This study is to select more various street trees. To accomplish this, evaluation criteria and detailed indexes were created. The importance was indicated through the Analytic Hierarchy Process. For commercial roads, the priority of landscape characteristics is 0.2640, and among detailed indicators, the priority of shape is 0.1245. For work roads, the priority of landscape characteristics is 0.2496, and among detailed indicators, the priority of shape is 0.1177. For work roads, the priority of characteristics of civil service is 0.2250, and among detailed indicators, the priority of shape is 0.1177. For general roads, the priority of maintenance characteristics is 0.2479, and among detailed indicators, the priority of shape is 0.1062. For historical and cultural roads, the priority of regional characteristics is 0.3488, and among detailed indicators, the priority of regional characteristics is 0.1643.

As the online education market expands, educational contents with various presentation methods are being developed and released. In addition, it is imperative to develop content that reflects the usability and user environment of users who use this educational content. However, for qualitative growth of contents that will support quantitative expansion of markets, existing model analysis methods are urgently needed at a time when development direction of newly developed contents is secured. In this process of content development, a typical model for setting development goals is needed, as the rules of the prototype affect the entire development process and the final development outcome. It can also provide a positive benefit that screens the issue of performance dualization between processes due to the absence of communication between a single entity or between a number of entities. In the case of AR-based educational content which is effective to secure data necessary for development by securing samples of similar categories because there are not enough ready-made samples released. Therefore, a big data statistical analysis service is needed that can easily collect data and make decisions using big data. In this paper, we would like to design analysis services that enable the selection and detection of intuitive multidimensional factors and attributes, and propose big data-based statistical analysis services that can assist cooperative activities within an organization or among many companies.

This study was conducted to understand the effects of participation perception, self-efficacy, self-esteem, and empowerment on self-support intention of self-support work project participants. For this study, a survey was conducted on participants in the self-support work project within the G-gu area. As a result of the study, it was found that the participation perception, self-efficacy, and empowerment of participants in the self-support project had a positive (+) effect on the self-support will. Also, in the process where participants' perceptions of participation, self-efficacy, and self-esteem affect the will to self-support, it was found that empowerment partially mediated participation perception and self-efficacy and fully mediated self-esteem. Based on these results, the following are practical suggestions for improving self-support project participants' will to self-support as follows. First, systematic training courses are needed in the application and selection of recipients, establishment of self-support plans, and gateway training courses so that participants in self-support projects can correctly recognize self-support projects. Second, it is necessary to systematize the case management system provided by the self-help center and re-establish the role in order to strengthen the participants' hope for self-reliance. Third, it is necessary to identify the strengths of the participants in the self-support project, create results for self-support, and operate a program that strengthens the latent motivation to solve their own problems and change their behavior. Fourth, the empowerment of participants and professional ability of practitioners should be strengthened so that participants can solve the alienation and social exclusion experienced in the process of participating in the project.

In this study, a class operation case of an engineering design project targeting a golf ball dispenser, a commercial product, was presented. The project was carried out according to the systematic engineering design approach suggested by Kim Jong-won and W. Beitz. This method broadly divides engineering design into four stages: 'product planning → conceptual design → basic design → detailed design'. In particular, the conceptual design stage is divided into 'functional structure diagram → detailed working principle exploration → various design alternatives creation → optimal design selection'. In the conceptual design, the input/output of the golf ball dispenser was defined and a functional structure diagram was prepared for it. Through this process, it was possible to subdivide the functions of the product and to easily explore the working principle for each. The searched working principles are devised as various design alternatives by various combinations, and for each proposal, the advantages and disadvantages were compared with each other to derive the optimal design alternative. In the basic design, the prototype layout was completed through failure mode analysis and the actual prototype was manufactured using it. Through the entire process, students participating in the class will be able to design commercial products in a systematic way and experience manufacturing prototypes within the department of mechanical engineering curriculum.

Materials used for education are materials such as SM20C, Al6061, and acrylic. SM20C materials are carbon steel and are often used in certification tests and functional competitions, but are also widely used in industrial sites. The Al6061 material is said to be a material that has lower hardness and stronger flexibility than carbon steel, so it is a material that generates a lot of compositional selection of tools. If students are taught practical training using acrylic materials, vibration occurs due to excessive cutting in some parts and damage to the tool occurs. In this process, we examine to what extent the impact on the 2NC head, which is a five-axis equipment, can affect precision control. The weakest part of the five-axis equipment can be said to be the weakest part of the head that controls the AC axis. When the accuracy and cumulative tolerance of this part occur, the accuracy of all products decreases. Therefore, the core part of the 2NC head, the spindle housing, was carried out using an Al7075 T6 (Alcoa, USA) material. In the process of vibration and cutting applied to this material, the analysis was conducted to find out the value applied to the finite element analysis under extreme conditions. It is hoped that this analysis data will help students see and understand the structure of 5-axis machining rather than 5-axis cutting.
