Radioactive waste accepted to the repository of land disposal should have the capability of a safe isolation. To develop those requirements and evaluation techniques, the foreign criteria and the important characteristics, relevant to waste forms and management processes, were reviewed. Based on such studies as the evaluation techniques, “general acceptance criteria”that the radioactive waste forms generated in Korea should be met were suggested.

Interest in communities continues to grow. Policies to support the community are also being strengthened. However, the problem of developmentalism that destroys the community is still present. Although it has been revealed clearly in the Four Major Rivers project, developmentalism still dominates the community. Reform of developmentalism is very important for the protection and upbringing of the community. It can be done through reforms of institutions that make developmentalism work. It can also be a result of reforms in development laws and development agencies. The reform of laws related to the land compulsory acceptance system and the reform of the development corporations including the Water Resources Corporation(the K-Waters). Here, it is necessary to transform the composition of 'community versus state' into a composition of 'community and state'. Communities and states should have complementary relationships for good societies. The reform of developmentalism is a core task.

Sustainable development is important because the ultimate objective is efficient development combining the economic, social, and environmental aspects of urban conservation. Despite Korea's rapid urbanization and economic development, the distribution of resources is inefficient, and land-use is not an exception. Land use distribution is difficult, as it requires considering a variety of purposes, whose solutions lie in a multipurpose optimization process. In this study, Yangpyeong-eup, Yangpyeong, Gyeonggi-do, is selected, as the site has ecological balance, is well-preserved, and has the potential to support population increases. Further, we have used the genetic algorithm method, as it helps to evolve solutions for complex spatial problems such as planning and distribution of land use. This study applies change to the way of mutation. With four goals and restrictions of area, spatial objectives, minimizing land use conversion, ecological conservation, maximizing economic profit, restricting area to a specific land use, and setting a fixed area, we developed an optimal planning map. No urban areas at the site needed preservation and the high urban area growth rate coincided with the optimization of purpose and maximization of economic profit. When the minimum point of the fitness score is the convergence point, we found optimization occurred approximately at 1500 generations. The results of this study can support planning at Yangpyeong-eup.ausative relationship between the perception of improving odor regulation and odor acceptance.

Purpose: This study is to examine the intention of the elderly who live alone in the customized AI speaker for the elderly living alone to improve the quality of life service for the elderly living alone in the smart city environment. Based on the quality of life model of the elderly, this study is applied to the technology acceptance model to investigate the relationship between perceived usefulness and ease of use on the sustained use intention. Research design, data and methodology: Residents in Suwon, Gyeonggi-do, selected as candidate local governments for the Smart City Challenge Project of the Ministry of Land, Infrastructure and Transport in June 2019 to measure the perceived technology acceptance of potential users for the AI technology for the elderly living alone as part of the smart city technology. In order to evaluate the intention of using AI speaker, which is the target system of this study, a video of a chatbot using experience of elderly people living alone was produced. Results: First of all, in order for the elderly living alone to have an attitude to use AI-based speakers, there should be a perceived usefulness of the quality of life of the elderly. However, ease of use did not show any significant causal relationship to attitude toward use. In addition, the attitude toward use weakly influenced the intention to use. In other words, elderly people living alone were not likely to have a significant effect on their attitude toward use. However, feeling that AI speakers are easy to use will help to improve the quality of life, which in turn led to the attitude toward using AI speakers, which could lead to indirect effects. Finally, the perceived usefulness of quality of life was found to have a weak effect on direct use intentions. Conclusions: This study conducted a study on the technology acceptance of service environment to improve the quality of life for the specific user group who live alone in the smart seat environment. In this study, we examined the effects of AI speaker on the elderly living alone to improve the quality of life for the elderly living alone.

In this study aviation authority officials were classified into four cultural groups according to culture theory, and then questioned to determine the effects of cultural bias on their social acceptance of a new air traffic flow management system. Based on previous studies, cultural biases were categorized as egalitarianistic, individualistic, fatalistic, and hierarchical, and social acceptances were considered to be influenced by four variables, that is, perceptions of usefulness, work attitude, intention to use, and behavior (job absorption). Empirical analysis showed that hierarchy had a significant positive effect on social acceptance, and egalitarianism was found to have a significant positive effect on social acceptance with 95% credibility. We propose the organizational culture of Korean government be changed to accept the diverse opinions of government officials during the implementation phase of the new system recommended by ICAO.

This study was undertaken with 237 fifth grade children to investigate the factors, affecting the seafood prefrerence of elementary school children as one of the approaches to find strategies to promote these children's acceptance of seafoods. Subjects for this study were from one public elementary school under meal service located each in Boryeoung-city Chungcheongna Co (coastal area) and Chelowon gen Gangwon do land locked area) The preferences for than those in Boryeong and differences in may items were significant Among four area gender groups girls in Cheolwon had the lowest preference for most seafood items except cephalocoda for which the preference of body in Cheolwon was the lowest Making soup was the least preferred method to cook fish regardless of gender and area, while grilling was the most or the second most preferred in each gender area group Compared to girls bodys had a higher preference for deep frying The seafood preferences of mothers in both areas were similar to those of their children except for processed seafoods which were even more preferred by the children than mothers. Gender, distance from the sea and the method of preparation/cooking seemed to affect the children's preference more than their mother's preference and frequency of serving in the case of seafood. And the effect of gender distance from the sea and cooking methods differed for each seafood category The several suggestions to improve seafood preference especially in land locked area are discussed.

Contributed acceptance system is causing problems with the usefulness and follow-up services and the like, other than the origin purpose which needs to be operated as rational adjustment method between the public interest and the private. Accordingly, this study has examine the problems by analyzing the present condition of practical public facilities and has the purpose on drawing the improvements by conducting consciousness survey from in substance users. The problems drawn from the analysis and the survey are location and position of the public facilities by reason of making public facilities at leftover land, the awareness and use as in-site facilities, creating street facilities without considering the use and safety of the users, follow-up service issues and the usefulness issues by creation without considering the surrounding conditions. The proposal of improvements for efficient operation by each problems are devising plans by considering location and position of the facilities for utilization and usefulness, secondly the necessity of the public relations for the improvements of the utilization of public facilities. thirdly, conducting the legal obligation by installing direction boards for its awareness of public facilities and delegating operation of facilities to public corporations such as SH, LH and inhabitants for efficient follow-up services, lastly, establishing the public facility map service which could figure out the surrounding conditions of public facilities to utilize for the contributed acceptance.

As our global population grows each day, it is apparent that we must find new ways to provide space for habitation and the services necessary to support large urban areas. It is no longer advisable nor acceptable to continue to expand our cities on the surface, encroaching on valuable agricultural land and open space. We must also find ways to be more energy efficient in every aspect of our societies. Effective use of underground space can provide the space necessary to accommodate larger populations and the services necessary for their support in existing urban areas we can also find new ways to utilize underground facilities to improve urban efficiency and function. Underground technology has improved dramatically in the last two decades and continues to evolve to meet a great variety of applications. The confluence of available technology, economic feasibility, and greater acceptance of underground solutions with recognition of the need to change the ways we build and use out urban areas and their surrounding environment indicates that we are witnessing only the beginning of appropriate and innovative use of underground space future generations will indeed 'Think deep'.

The layout is an important and difficult problem in industrial applications like sheet metal manufacturing, garment making, circuit layout, plant layout, and land development. The module layout problem is known to be non-deterministic polynomial time complete(NP-complete). To efficiently find an optimal layout from a large number of candidate layout configuration a heuristic algorithm could be used. In recent years, a number of researchers have investigated the combinatorial optimization problems by using neural network principles such as traveling salesman problem, placement and routing in circuit design. This paper describes the application of Self-organizing Feature Maps(SOM) of the Kohonen network and Simulated Annealing Algorithm(SAA) to the layout problem of the two-dimensional rectangular shapes.
