Recently, it has been issued whether the current permission standards for forest land-use conversion is adequate or not. This study was aimed at evaluating the propriety of the current permission standards using the Delphi technique, which is one of survey techniques regarding experts's opinions. The results of the survey indicated that the standards related to the connection development restriction and the height of the first berm were underrated in most of the evaluation factors. The size limit and the altitude restriction of the land-use conversion also have a low propriety or applicability due to their vagueness. In case of average slope, its applicability was rated as significantly low because there is no standardized method for estimating or verifying the average slope. A statistical analysis based on coefficient of variation and one-way ANOVA were conducted to examine whether each group of experts agree with these survey results. It is appeared that the survey using Delphi technique could successfully achieved an agreement from each group of experts. Overall, evaluation factors considered in this study seems to be effective to verify the problems of each standards and to guide to improvement of the standards.

With the active utilization of Online Judge (OJ) systems in the field of education, various studies utilizing learner data have emerged. This research proposes a problem recommendation based on a user-based collaborative filtering approach with learner data to support learners in their problem selection. Assistance in learners' problem selection within the OJ system is crucial for enhancing the effectiveness of education as it impacts the learning path. To achieve this, this system identifies learners with similar problem-solving tendencies and utilizes their problem-solving history. The proposed technique has been implemented on an OJ site in the fields of algorithms and programming, operated by the Chungbuk Education Research and Information Institute. The technique's service utility and usability were assessed through expert reviews using the Delphi technique. Additionally, it was piloted with site users, and an analysis of the ratio of correctness revealed approximately a 16% higher submission rate for recommended problems compared to the overall submissions. A survey targeting users who used the recommended problems yielded a 78% response rate, with the majority indicating that the feature was helpful. However, low selection rates of recommended problems and low response rates within the subset of users who used recommended problems highlight the need for future research focusing on improving accessibility, enhancing user feedback collection, and diversifying learner data analysis.

As the entrepreneurial ecosystem turns out to be a leading factor in improving nation's entrepreneurship, many studies are underway in the country to develop the start-up ecosystem. Although the entrepreneurial ecosystem is receiving attention as an essential factor for the nation's economic growth as well as entrepreneurship due to its inter-relationship with start-ups, government agencies and investors, criticism of measurement indicators has been increasing due to the different institutional and political contexts of each country, including the various definition of start-up ecosystem. In this study, we develop indicators that are suitable for domestic conditions in Korea and that can measure the level of start-up ecosystems in each regional level. FGI and Delphi surveys by scholarly experts in each field of start-ups & entrepreneurship were conducted to verify how well existing indicators fit the domestic situation and to develop indicators that can measure the local entrepreneurial ecosystem in Korea through close examination. As a result, the local entrepreneurial ecosystem consisted of three to four sub-components and 38 sub-components, each consisting of seven indicators, including Policy, Investment, Culture, Market, Human Capital, Support and Knowledge. It is expected that this research will be used to diagnose local start-up ecosystems and to propose discriminatory policies that can complement regional strengths and weaknesses.

Recently, with the demand for airservice increasing and localization accelerating, airport construction is booming. However, in the case of an unsuitable airport site selection, it might cause a reduction in airport service and a decrease in airport demand. Thus, it is necessary to construct a representative airport and choose a suitable site selection method for economical and efficient airports in order to make the utmost use of airport functions. In this study, GSIS was used to select the airport site and applied to case study areas. GSIS could present a new method for efficient and scientific analysis in airport site selection including various factors over an extensive area. The use of both, the paired comparison method and the delphi method, could improve the objectivity of analysis results in the process considering the relative weight grade of data and priority order of analysis factors, used in airport site selection.

The purpose of this study is to evaluate the technological competitiveness of the environmental industry with developed countries in order to establish an international market expansion strategy of the Korean environmental industry and technology. In order to evaluate the competitiveness of the environmental industry and technology, core technologies were classified by the environmental industry sectors based on the classification system of the domestic and international environmental industry and technology. After developing the evaluation index data, the Delphi analysis, journal and patent analysis, as well as the export and import analysis were carried out and the standardization analysis was performed on the index data. Moreover, the weights of each evaluation index were calculated using the AHP(Analytic Hierarchy Process) method and the evaluation results of competitiveness of the environmental industry and technology in Korea, the United States, the United Kingdom, Germany, and France were derived. As a result of the evaluation, the United States was rated with the highest technological competitiveness in all the environmental industry sectors, while Korea got the lowest technological competitiveness rating compared to the 4 developed countries. In particular, Korea got the lowest level of technological competitiveness in the sector of multi-media environmental management and development for a sustainable social system. Therefore, in order for the Korean environmental industry and technology to enter the global advanced market, it is necessary to strengthen the competitiveness through the development of the fourth environmental industry based on IoT(Internet of Things), cloud, big data, mobile, and AI(Artificial Intelligence), which are currently the country's domestic strengths.

The importance of searching the weak signal has been increasingly recognized to cope with rapidly changing circumstances as an environmental analysis technique. This study proposed the NEST process for the searching for the weak signal. The NEST (New & Emerging Signals of Trends) is a micro environmental analysis process based on both quantitative and qualitative method. For this, the weak signal Searching Board is developed and traditional methods as global monitoring, trend analysis, brainstorming and delphi method are implemented to NEST. The NEST process is consists of three stage modules; the global monitoring stage in search of seeds information related to the environmental change, the weak signal analysis stage using the weak signal Tracking Board, and the delphi valuation stage for objectifying the final result. The NEST provides the weak signal of the promising technology which can bring new paradigm and the Up-Coming Trends which can lead new trend in the future. These outputs can be used to select promising technology from firm level to national level. The NEST system can be effectively operated as well as in small group so that small and medium innovative firms can develop and execute their own NEST process individually.

Having started with "Space War", the first game produced by MIT in the 1960's, the gaming industry expanded rapidly and grew to a large size over a short period of time: the brand new games being launched on the market are found to contain many different elements making up a single content in that it is often called the 'the most comprehensive ultimate fruits' of the design technologies. This also translates into a large increase in the number of things which need to be considered in developing games, complicating the plans on the financial budget, the work force, and the time to be committed. Therefore, an approach for analyzing the elements which make up a game, computing the importance of each of them, and assessing those games to be developed in the future, is the key to a successful development of games. Many decision-making activities are often required under such a planning process. The decision-making task involves many difficulties which are outlined as follows: the multi-factor problem; the uncertainty problem impeding the elements from being "quantified" the complex multi-purpose problem for which the outcome aims confusion among decision-makers and the problem with determining the priority order of multi-stages leading to the decision-making process. In this study we plan to suggest AHP (Analytic Hierarchy Process) so that these problems can be worked out comprehensively, and logical and rational alternative plan can be proposed through the quantification of the "uncertain" data. The analysis was conducted by taking FPS (First Person Shooting) which is currently dominating the gaming industry, as subjects for this study. The most important consideration in conducting AHP analysis is to accurately group the elements of the subjects to be analyzed objectively, and arrange them hierarchically, and to analyze the importance through pair-wise comparison between the elements. The study is composed of 2 parts of analyzing these elements and computing the importance between them, and choosing an alternative plan. Among these this paper is particularly focused on the Delphi technique-based objective element analyzing and hierarchy of the FPS games.

As the boundaries between disciplines have been weakened and interdisciplinary or multidisciplinary subjects have increased, there is a limitation to express subjects with DDC. This study evaluates DDC instructions using interdisciplinary numbers and classifying more than one discipline through Delphi research. As a result, it is found that there is a need for defining separately 'interdisciplinary subjects' and 'multidisciplinary subjects', based on the level of integration among disciplines, and improving the instruction to maintain the consistency in assigning and filing classification numbers. It is also discussed that to enhance the symbols' power of expression, an analytic/synthetic method could be adopted.
