Countries around the world are making active efforts to reduce greenhouse gas emissions. Korea is also pursuing a policy of abolishing aging coal power and converting it to LNG power generation. However, in Korea, gas turbine manufacturing technology has not been localized, so all of it is imported and installed from overseas manufacturers. Therefore, this paper examines the domestic and foreign environment of the gas turbine power generation industry and proposes a strategy to develop and expand the supply of Korean gas turbine technology by applying the PEST-SWOT-AHP methodology. As a result of the research, the strategy to develop and expand the supply of Korean gas turbine technology can be summarized as 1) strengthening the role of power generation public enterprises to develop and promote commercialization of gas turbine technology, 2) expanding the proportion of LNG power generation to reduce greenhouse gases, 3) the government's active efforts to create an ecosystem for the gas turbine industry, and 4) forming a public consensus on the construction of LNG power plants.

Today, high-speed rail is gradually increasing in importance as an eco-friendly means of transportation responsible for the movement of people between regions. In the past, problems of inefficiency continued due to monopolistic operation of the railway industry, and with the introduction of a public enterprise competition system, KTX and SRT operating organizations are making efforts to expand service quantity and improve quality. However, the high-speed rail service quality evaluation was limited to modifying and supplementing indicators from the operator's perspective suitable for past quality evaluations, and the evaluation target or method was not specific. Therefore, in this study, we developed a hierarchical model to measure high-speed rail customer service quality based on the model of Brady and Cronin(2001) and applied the analytical hierarchical decision-making method(AHP) to derive the priorities of Korea's high-speed rail competitiveness factors. Based on the results, it is believed that introducing reasonable and standardized service quality indicators will contribute to establishing a marketing strategy to improve the customer service competitiveness of high-speed rail operators.

This study evaluates the safety and usability of three underground walkways in Seoul by applying Crime Prevention Through Environmental Design (CPTED) principles. The 2024 survey focused on five key concepts: Access control, Surveillance enhancement, Maintenance, Legibility enhancement, and Territorial usability enhancement. The results showed that Access control in the underground walkways was limited. While Surveillance enhancement proved effective in some walkways, Legibility and Territorial usability enhancements were generally lacking. Ultimately, using the Analytic Hierarchy Process (AHP) for evaluation, both the Yeoksam and Jonggak underground walkways received a "Very Good" rating, while the Seolleung underground walkway received a "Good" rating. The research highlights the need for improvements in applying CPTED principles to underground walkways and emphasizes the importance of continuous maintenance. These measures, the study suggests, will contribute to crime prevention and enhance the overall usability of these spaces.

Recently, various researches have been studied on the predict method of land change according to its development. The Cellular Automata(CA) is one of the most popular methods in the urban growth modeling. The basis principle of CA is to repeat operations, which convert the current cell into new cell state by the transaction rule. It will minimize the loss of data by using Fuzzy-AHP and it can lead the flexible urban growth modeling. However, AHP would have a disadvantage to repeat the procedure of the collecting intentions until it derives the weight. Also, it is necessary for the simulation of CA to repeat the operations and the test of data accuracy should be accompanied. The purpose of this study is to predict the Busan city growth model and analyze it according to the automated test method by applying CA as well as Fuzzy-AHP. This study shall improve the difficulties caused by complexity and repetitiveness in the urban grow modeling. The practical modeling could be derived from the verification, and the derived modules could be applied to the similar case studies.

The purpose of weighting traffic management strategies is to reach strategic goal through intended and balanced implementations. The AHP is commonly used technique to derive perspective and strategic goals, and to give priorities to them in a organization. In this study, perspective and strategic goals are derived through surveys and interviews with staffs of a traffic management agency. And then, priority of perspective and strategic goals is performed through the AHP. In this study, three things were identified. Firstly, it was found weighting perspectives such as values for customers, future, activity, and performances were in sequence performed. The value for customers were ranked the first. Secondly, it was found increasing of customer- centric thinking and values of eco- friendly system are the highest weighting in strategic goal. Third, it was found increasing of customer-centric thinking is the most important in headquarters and regional headquarter. But, Values of eco-friendly system is ranked as the most important in opinion of branch office's staffs. It was also identified that depending on the working places, such as headquater and branch offices, the response differs.

The lack of water resources is becoming a serious issue throughout the world. The water shortage in Korea is expected to increase. Groundwater can be a solution to this matter in some places. Especially, bank filtrations are known to be advantageous over conventional reserviors, even if they have some drawbacks such as their limited location for development and small sizes. The AHP(Analytic Hierarchy Process) is an analytical tool, supported by simple mathematics, which enables one to explicitly rank tangible and intangible factors against each other for the purpose of resolving conflicts or setting priorities. In order to check the applicability of AHP to the evaluation of bank filtration sites, four candidate locations were chosen. They have suffered from problems like water-supply shortage and delayed dam construction. The analysis results are compared with those of the previous study using a conventional method. It is believed that the developed method can a basis for reasonable decision-making regarding bank filtration development.

Recently, many construction firms fall on hard times because construction business continues to stagnate. In this paper, we analyze the efficiency of the listed construction firms using a combined AHP and DEA model. In order to determine the input and output factors of DEA, the AHP model is applied to evaluate the importance of input and output factors. The benchmarking companies and efficiency value for the construction firms with inefficiency are also provided to improve the their efficiency. We analyzed the 57 listed companies consisted of 36 listed on KOSPI and 21 listed on KOSDAQ at the end of 2009. The analysis results show that eleven companies whose values of CCR are 1, and fourteen enterprises whose values of BCC efficiency are 1. In additions, the eleven firms have the scalability efficiency. Finally, we test the correlation between efficiency and the stock price and the correlation coefficient of efficiency group is 0.7 in the CCR model.
