  • A new way to integrate various geophysical information for evaluation of RQD was developed. In this study, we does not directly define the RQD value where borehole data are not sampled. Instead, we infer the probability of RQD values with prior probability of data directly obtained from borehole, and secondary supporting probability from resistivity and seismic tomography data. First, we applied the geostatstical indicator kriging to get prior probability of RQD value, and indicator kriging with soft data to get the supporting probability from resistivity and seismic data. And we finally applied the permanence ratio rule to integrate these information. The finally obtained result was also analyzed to fully utilize the probabilistic features. For example, we showed the probability of wrongly classifying the RQD evaluation and vice versa. This kind of analytical result may be used for decision making process based on the geophysical exploration.

  • This paper aimed to reveal the needs and intentions of the people with developmental disabilities through AAC for supporting their independent living in the community and furthermore to contribute to realizing an inclusive community. From August 7 to September 11, 2020, trained researchers conducted 1to1 interviews(AAC) with 74 people recommended by specialized institutions. Data were analyzed by frequency-analysis, Chi-square-analysis and T-test using SPSS 25.0. As a result, the creation of community-level conditions(ex. housing and employment) and job aptitudes and preferences are important for the independent living and expectations and desires for social participation were high. It is different from the previous survey results through agents. It means the policy for the developmentally disabled should be based on their needs and aim for 'living in the community as a community member'. Based on these results, the implications of supporting decision-making for the ordinary lives of people with developmental disabilities were suggested.

  • This paper aims to explore the characteristics of regional embeddedness of Korean firms in Daren City, China, with special reference to management practices. To achieve this goal, I attempt to analyze the type and structure of the firm, the structure of decision-making, labor practices, and the inter-organizational networks with the government, trade associations and the business supporting agencies. The major purpose of the investment in Daren by Korean firms is to penetrate and expand the local market. In line with this, the structure of decision-making by Korean firms tends to become increasingly autonomous, especially in terms of employment and marketing. However, the decision-making related to finance and accounting tends to be still highly controlled upon the headquarter in Korea. In addition, it is shown that Korean firms make a great effort to sustain the cooperative relationships with the local society and the local government.

  • Leading the fourth industrial revolution era requires science and technology strategies that establish original research directions at the national level. To this end, it is necessary to look at the research and development activities for the fourth industrial revolution of technology-leading countries. In this study, the research programs of the U.S. Intelligence Advanced Research Projects Activity(IARPA), an organization focusing on cutting edge research on science and technology information such as artificial intelligence, are investigated by using network analysis. The findings show that, resolving around the information identification and forecasting, decision making and cybersecurity clusters, IARPA's research programs largely focus on finding hidden information and predicting specific events, supporting decision making by considering changes in and outside organizations or establishing cybersecurity. Also, this study finds that China and Japan, representative technology-leading Asian countries, refer to the research programs of IARPA to establish their science and technology policies. The results of this study suggest implications for Korea's science and technology policies in response to the fourth industrial revolution era.

  • To maintain the normal function of an aging building, regular inspection, repair, and reinforcement must be performed. However, the form of information and decision-making generated in the current building maintenance stage still depends on inefficient methods. This causes an increase in cost and waste of time in building maintenance. Therefore, this study proposed a COBie-IM document for building inspection and maintenance information management by benchmarking COBie, and suggested a method of checking information by linking it with BIM. In addition, a method for visualizing the designation of colors according to the damage grade of defects occurring in the building was suggested. Through this, we are able to systematically integrate and manage the information generated during inspection and maintenance in the building maintenance stage. This is expected to increase work efficiency by supporting decision-making that determines the priority of repair and reinforcement for defects.

  • Purpose: This study was a descriptive methodological study to develop protocols for school health practice to manage health problems of primary school students effectively. Methods: The protocols were verified by 12 experts and 10 health teachers, respectively, to secure a two-step content validity. Results: The main 8 health problems of primary school students were headache, abdominal pain, musculo-skeletal, respiratory, circulatory, ophthalmic, and oral-dental problems, and fever. The developed protocols consist of 8 algorithms, which are to help decision making in the course of assessing health problems and to identify and link related factors and associated symptoms, 8 school nursing records based on the Omaha classification system, and the list of 441 links between nursing assessment and nursing intervention. Conclusion: The use of the protocols is expected to make it easier for health teachers to apply the nursing process in solving the health problems of primary school students and supporting the rational decision making process, eventually improving the quality of primary school health. Repeated studies for protocol standardization as well as studies dealing with various health problems not included in the protocols should be performed for the development of school health practice protocols.

  • Graphic health warning on the tobacco product package is a cost-effective tobacco control policy to convey information on harmful effect of tobacco use to health, and it is known not only to motivate smokers to quit but also to deter adolescents from start smoking. In case of Korea, amendments to National Health Promotion Act requiring implementation of graphic health warning had been submitted 13 times, from 2002 to May 2015. In May 2015, the amendment had been approved by the National Assembly and it enters into force on December 23, 2016. This research analyzed the discussions from Health and Welfare Committee of the National Assembly during the implementation of the graphic health warning in order to study decision making process of legislators. Study found that there was a shift from a general opposition on implementing graphic health warning at first to a harsh conflict over relaxation of the regulation once discussing the implementation in earnest. Particularly, while the group supporting the implementation of the graphic health warning or opposing relaxation advocated the amendment with scientific and knowledge-based evidences including the World Health Organization Framework Convention on Tobacco Control, the group opposing the adoption of the amendment itself or suggesting relaxation tended to defend their position with empathy on smokers or tobacco industries.

  • Weapon target assignment problem is an essential technology for automating the operator's rapid decision-making support in a battlefield situation. Weapon target assignment problem is a kind of the optimization problem that can build up an objective function by maximizing the number of threat target destructed or maximizing the survival rate of the protected assets. Weapon target assignment problem is known as the NP-Complete, and various studies have been conducted on it. Among them, a greedy heuristic algorithm which guarantees (1-1/e) approximation has been considered a very practical method in order to enhance the applicability of the real weapon system. In this paper, we formulated the weapon target assignment problem for supporting decision-making at the level of artillery. The lazy strategy based on hierarchical structure is proposed to accelerate the greedy algorithm. By experimental results, we show that our algorithm is more efficient in processing time and support the same level of the objective function value with the basic greedy algorithm.

  • This paper presents a dynamic development of an ontology-based statistical information system supporting the collection, storage, processing, analysis, and the presentation of statistical knowledge at the national scale. To accomplish this, we propose a data mining technique to dynamically collect data relating to citizens from publicly available data sources; the collected data will then be structured, classified, categorized, and integrated into an ontology. Moreover, an intelligent platform is proposed in order to generate quantitative and qualitative statistical information based on the knowledge stored in the ontology. The main aims of our proposed system are to digitize administrative tasks and to provide reliable statistical information to governmental, economic, and social actors. The authorities will use the ontology-based statistical information system for strategic decision-making as it easily collects, produces, analyzes, and provides both quantitative and qualitative knowledge that will help to improve the administration and management of national political, social, and economic life.
