본 연구에서는 KOH 용액을 사용한 Si 습식 이방성 식각실험 진행 후, 나타나는 표면의 거친 현상을 완화하는 데에 중점을 두고 연구를 진행하였다. 이를 위해 $SiO_2$ 웨이퍼 위에 Photo-lithography 공정으로 형성시킨 PMER 패턴을 Mask로 사용하여 HF 용액으로 $SiO_2$를 식각시켰으며, 형성된 $SiO_2$를 Mask로 사용하여 KOH 용액으로 Si을 식각시켰다. 이 때, KOH와 혼합하는 용액으로 IPA와 Ethan이을 각각 사용하여 실험을 진행하였으며, ESEM을 이용하여 표면을 비교하였다.

This study focuses on developing a theoretical framework for evaluating Operational Performance of the Marine Forest Creation project on a balanced and comprehensive perspective by using BSC, AHP, and IPA. Also, the purpose of this study is empirically to analyze operational performance of the project and to suggest the future improvement plan. For this purpose, We will first determine the critical success factors(CSF) and key performance indicators(KPI) required for evaluating the performance of the Marine Forest Creation project from the four perspectives of BSC. And, After determining the weight for each of CSF, KPI, and four perspectives of BSC by using AHP, we will measure the project performance. We will also conduct IPA analysis to propose the direction of improvement of the Marine Forest Creation project. The results of this study are as follows. First, this study has drawn 8 critical success factors and 16 key performance indicators for four BSC perspectives based on the theoretical considerations and expert interview survey. Second, as a result of deriving relative importance of BSC perspectives using AHP, customer perspective was the highest, followed by financial perspective, learning and growth perspective, and internal process perspective. Third, as the results of analyzing the importance and performance of BSC perspectives using IPA, customer perspective was the maintenance reinforcement category, financial perspective was the key improvement category, internal process perspective and learning and growth perspective were gradual improvement category. This study has a great academic significance in terms of BSC first tried to evaluate the performance of the Marine Forest Creation project. The results of this study are expected to lead to various discussions for a balanced and comprehensive verification of Marine Forest Creation project performance.

This study is aimed to point out the direction for more reasonable and effective application of future digital technology in the exhibition. It's also to improve the satisfaction of visitors' overall experience through inspecting the special exhibition using digital technology in the national central museum in 2019. The relationship of visitors' expectations, experience and satisfaction are analyzed through literature investigation. Hence, four dimensions of digital experience were summarized on this basis, the content of the questionnaire was set through this research. The satisfaction of visitors to the digital technology experience was evaluated and the key contents needing to be improved were found through Importance-Performance Analysis (IPA). According to the IPA analysis, the content located in quadrant IV is analyzed emphatically, and improvement suggestions are put forward from macro-level, micro-level and viewer's inner levels. The results can be used as a reference for improving the feasibility of the current problem. In order to ensure the forward-looking and timeliness of this field, continuous research will be conducted according to the changes and developments.

The total amount of overseas plant orders obtained by Korean construction companies in 2015 decreased by approximately 51% from the previous year. While a chemical plant sector has the highest portion of the plant orders by accounting for 63% of the plant industry, its orders also decreased by approximately 43% in the same year. Recently, plant construction companies in overseas projects have been dominating the engineering sector owing to their advanced technology, experience, and accumulated knowledge. Therefore, measures must be taken to secure the competitiveness of domestic companies in the global plant industry. Especially, productivity management is an important issue to strengthen the national competitiveness with the development of construction technology. As the productivity influences long term growth, we analyze productivity obstacle factors by using the revised IPA, a technique to measure attribute importance and performance. With the identified factors, we suggest improvement plans and measures to enhance productivity of overseas chemical plant projects. This study will help the companies to come up with medium and long term measures by discussing results and implications it provides.

The purpose of this study was to derive policy priorities for fostering the biopharmaceutical industry. In this study, the urgency and importance of the policy to foster the biopharmaceutical industry in Gyeonggi-do was investigated, and the priorities of the policy in the biopharmaceutical industry were analyzed through IPA analysis. As a result of the study, the top priority support tasks for the biopharmaceutical industry promotion policy were 'R&D support', 'Expert training', and 'commercialization support'. As a result of deriving policy priorities for each biopharmaceutical sector, 'R&D support' and 'Expert training' were found to be high in common, and differences in policy priorities for each industry such as cell therapy products and advanced bio-convergence products were confirmed. Also, as for the policy demand, R&D funding support, clinical trial support, and commercialization funding support were found to be high. Based on these results, the government's policy to foster the biopharmaceutical industry was supported with a focus on 'R&D support' and 'Expert training', and policy implications were drawn that customized support is needed in consideration of the characteristics of each industry field.

The purpose of this study is to analyze the difference between job importance awareness and actual job achievement of archivists of private universities through importance-performance analysis (IPA), and to analyze the difference between certified and noncertified archivists about the above two factors. To achieve the purpose, the detailed job activities were drawn through a review of laws, regulations, and policies. The detailed list of job activities was confirmed by a few current archivists, Using the confirmed list of detailed job activities, a survey was conducted for archivists of private universities. The collected data in the survey were analyzed using the IPA method. According to the study results, the two groups of archivists have a clear understanding of their jobs; however, environmental factors influence the actual achievement of the jobs.

The purpose of this study is to examine the importance and satisfaction of users in the use and selection of a dance academy and contribute to methods for the activation of a dance academy based on basic information. A questionnaire survey was conducted with 213 users attending 12 dance academies in G Metropolitan City using the IPA statistical method. The following conclusions were drawn. The highest importance of a dance academy in IPA analysis was a professional teacher, followed by clean dance equipment, transit accessibility, dance academy fee, and a kind teacher. The highest satisfaction was a professional teacher, followed by various dance programs, teacher's choreography ability, a kind teacher, and transit accessibility. Based on the findings, dance academy users felt that the professionalism and kindness of teachers who directly teach them, academy fee, and equipment cleanliness associated with the age of COVID-19 were important. High satisfaction factors were teacher-related factors and transit accessibility. Therefore, it is considered that a professional and kind teacher and clean and hygienic environment will contribute to the activation of a dance academy.
