Recently, the demand for atypical structures with functions and sculptural beauty is increasing in the construction industry. Existing mold-based structure production methods have many advantages, but building complex atypical structures represents limitations due to the cost and technical characteristics. Production methods using molding are suitable for mass production systems, but production cost, construction period, construction cost, and environmental pollution can occur in small quantity batch production. The recent trend in the construction industry calls for new construction methods of customized small quantity batch production methods that can produce various types of sophisticated structures. In addition to the economic effects of developing related technologies of 3D Concrete Printers (3DCP), it can enhance national image through the image of future technology, the international status of the construction civil engineering industry, self-reliance, and technology export. Until now, 3DCP technology has been carried out in producing and utilizing residential houses, structures, etc., on land or manufacturing on land and installing them underwater. The final purpose of this research project is to produce marine structures by directly printing various marine structures underwater with 3DCP equipment. Compared to current underwater structure construction techniques, constructing structures directly underwater using 3DCP equipment has the following advantages: 1) cost reduction effects: 2) reduction of construct time, 3) ease of manufacturing amorphous underwater structures, 4) disaster prevention effects. The core element technology of the 3DCP equipment is to extrude the transferred composite materials at a constant quantitative speed and control the printing flow of the materials smoothly while printing the output. In this study, the extruding module of the 3DCP equipment operates underwater while developing an extruding module that can control the printing flow of the material while extruding it at a constant quantitative speed and minimizing the external force that can occur during underwater printing. The research on the development of 3DCP equipment for printing concrete structures underwater and the preliminary experiment of printing concrete structures using high viscosity low-flow concrete composite materials is explained.

The purpose of this study was to explore relationships between family of origin and youth transitioning from out-of-home care. Data were collected from six youths transitioning from out-of-home care and were analyzed using the phenomenological approach. The results of this study were as follows. Four categories and twelve subcategories were drawn from the meaning units. The four categories were 'chaos in separation', 're-established relations but with distance', 'completely ended relationships with the family of origin', and 'redrawing family boundaries'. First, the participants who were separated from their parents due to poverty or divorce reunited with their parents, and they appeared to continue their relationships with the family of origin after transitioning from out-of-home care. The youth were receiving various forms of support from their parents in order to be independent, and they were experiencing stable independence through this support. Second, the participants who were separated from their parents due to serious child abuse or parental death had broken relationships with their parents. The youth were independent and relied on new alternative relationships that were not with the family of origin, but they experienced somewhat unstable self-reliance. In short, participants' relationships with families of origin in this study can be defined as a tight rope between love and hate. Based on these results, child welfare practice and policy implications were discussed to help out-of-home care youth's relationship with their family of origin.

With the entry into an aged society, interest and demand for the elderly are increasing. The rapid increase in the elderly is calling for change in various fields. As the opportunities and desires of the elderly to participate in society increase, research on services suitable for the elderly society is needed. Although the expansion of convenience facilities and improvement of the system are being made to solve problems arising from the elderly society, there are many shortcomings in the increasing demand of the elderly. In addition, due to aging, they have difficulty in living independently and independently due to the decline in their daily life ability and physical function. To solve these problems, the government and local governments provide various services for the elderly. The service for the elderly is provided based on the general characteristics of the elderly, so it has limitations in customized services. In this paper, present a service model using extended information in ICT-based services to complement these problems. Scalable information uses IoT environments to collect information and environmental information for the elderly. Service support using information on the expansion of the elderly shall identify the characteristics of the elderly and support appropriate services when users request services. The proposed method may support self-reliance services that reflect the characteristics and needs of the elderly.

This study was carried out to empirically analyze the hypothesis that the impact of the welfare status on the welfare attitudes is moderated by each individual's level of confidence in government. To do this, this study focused on the welfare status known as the significant predictors of welfare attitudes and measured the welfare status as a gap between 'welfare contribute' and 'welfare benefit' in a single dimension, which is defined as 'material sacrifice'. Also, this study examined the main effect of material sacrifice and trust in government on the welfare attitudes and moderating effect of trust in government on relationship between material sacrifice and welfare attitudes. This study was performed with secondary data from 8th year of "2013 Korea Welfare Panel Study". Hypothesis of this study were verified using hierarchical multiple regression analysis. The major findings of this study are summarized as follow. 'Material sacrifice' was found to be negatively associated with the welfare attitudes. However, as the confidence in which social policies will be carried out competently by government increases, it was confirmed that the negative effect of material sacrifice on the welfare attitudes was moderated. It suggests that self-material interests associated with welfare could be moderated by beliefs and expectations about the government's functions, which means that expanding the reliance on the social policy is an important task in order to lead a social consensus for the welfare expansion.

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.

This study is to examine the current situation of Korean sports culture and seek its pointing spot and alternatives to its advancement. First, out of the current situation of Korean sports culture, that of school physical education, even though it is the most significant basis for sports culture, is riddled with so many contradictions that the pace of its change is very slow. Only when the elite sport is normally operated and well coordinated, can it have the value of existence as a stable field. The mass sports have been determined to have insufficient self-reliance of sport facilities, sport programs and instructor management since the national policy for physical education has been focused on the elite sports. Second, internalization of "Winning First Policy" as a pointing spot of sports culture has been found to be an production of the value system with not only a very passive tendency caused by political changes. Accordingly, the concept of sports-culturism has been introduced as a new pointing spot of sports culture and then it has been emphasized that the sports-culturism is the awareness of sports advancement. Third, in terms of finding any alternatives to sports culture, enacting a school physical education promotion law has a very significant meaning as its advancement method. Next, the immorality of and match-fixing by sport organizations and the umpire's bad call have been mentioned as major problems to the elite sport, and also the alternative to each field has been set. Last, it has been assented with emphasis that Law of Sports for All should be enacted for the public sports to have any significance of the times.

The main purpose of this study is to explore the structure of local government social welfare finance and tendency of changing structure and what affects the change. We select GuRoGu budget from 2000 to 2007 as one of local governments in Korea to perform the study goal. After we analyzed the contents of the budget, we have developed the framework of analysis for reclassifying local government welfare budget. First of all, we find utility of the framework of analysis which classify local government social welfare budget as target groups, properties, and the source of the finance. Secondly, the structure of local government welfare finance has changed for 8 years. The rate of finance for direct service has risen more than that for indirect service, and the rate of finance providing material(or service) type has risen more than that of providing monetary type. The rate of the finance from central government has grown up rapidly, whereas that from local government has fallen off. The hypotheses that the rate of financial self-reliance and the increase rate of social welfare expenditure to the previous year play a significant role to the rate of social welfare expenditure are not clear in our study. But we find the central government's effects to the local government welfare budget has grown up. So, we propose if we analyze the hypothesis of incrementalism, we must divide the effects of the previous year expenditure from the effects of central government's policy.

This study addressed housing issues among various social problems of youth. With a focus on residential independence, this study analyzed the factors that lead youth to achieve residential independence. This study drew on nationwide data from the 'Youth Life Survey (2022)' with a sample size of 12,578. Binary logistic regression analysis was employed, with the dependent variable being residential independence. Key factors were as follows. The probability of residential independence was higher for men than women. Residential independence occurred mainly in non-metropolitan areas compared to metropolitan areas. Findings revealed that greater age, income, and assets facilitate achieving residential independence. In addition, public transport and cultural facilities were important for their residential independence, and it was found that the previous experience of residential independence had a positive effect. Policy implications derived from the findings are as follows. It is required to consider the heterogeneity and diversity of youth rather than implementing unitary policies. To ensure continuity and sustainability of self-reliance, long-term support programs are needed rather than temporary support. Moreover, it is required to offer public support comprehensively, instead of youth relying on support from personal networks, including their parents. An inclusive housing policy should be established to support youth for their residential independence in the future.
