This study reviewed the current status of low-experienced teacher librarians with less than 5 years and attempted to identify their educational needs through IPA analysis, Borich Priority Formula, and The Locus for Focus Model. A survey was conducted on low-experienced teacher librarians with less than 5 years of experience to analyze their process in the pre-service teacher training and experiences before an appointment and to identify teacher librarians instructional expertise. The results of the analysis of the study are as follows. First, there was a statistically significant difference between the importance and performance in all areas of instructional expertise of low-experienced teacher librarians. Second, 'reading education-practice progress' was recognized as a 'Keep up good work' with high importance and satisfaction, and 'library-based instruction planning, progress evaluation', 'information literacy-curriculum design', and 'digital and media literacy education-progress and evaluation' were recognized as areas of 'Concentrate here' through IPA analysis. Third, In the Borich Priority Formula, 'teaching-learning evaluation', 'teaching-learning progress', and 'teaching-learning plan' in the Library based instruction area showed the highest educational needs. Fourth, the library-based instruction was shown to the high discrepancy/high importancy area as same as the Borich Proity Formula. The results of this study can provide implications for improving the instructional expertise of teacher librarians.

With the development of digital technology, the marine environment is expected to change rapidly. In the case of autonomous vessels, technology is being developed in many countries, and the international community has begun to discuss ways to operate it. Changes in ships cause changes in the marine traffic environment and urge changes to aids to navigation. This study aims to analyze the cyber security management awareness of VTS personnel to improve the cyber security system for aids to navigation. To this end, the current status of cyber security management was reviewed with a focus on VTS, and a survey was conducted on VTS personnel. The survey analysis used the IPA methodology, and as a result of the analysis, a clear difference was observed in the perception of cybersecurity between those with experience in security and those without experience. In addition, technical measures related to cyber-attack detection and blocking should be implemented with the highest priority. The results of this study can be used as basic data for improving the cyber security management system for aids to navigation.

As the transfer of cargo functions to Gwangyang Port is completed, Yeosu Port has established a vision to become a hub for maritime tourism in Korea. Revitalization of the marine tourism industry through cruise development is recognized as a major strategy. Major domestic cruise tourism ports (Busan Port, Jeju Port, Incheon Port) have established a basic plan for fostering port cruises in response to the "Basic Plan for the Promotion of the Cruise Industry" established in 2016. However, the plan for Yeosu Port is insufficient. The cruise tourism industry, which is in recession due to Corona 19, is expected to recover due to with-Corona and Post-Corona. Therefore, Yeosu Port needs to take the lead in promoting the cruise industry to prepare for this. Accordingly, this study intends to derive evaluation items for the fostering of the Yeosu Port cruise industry through prior research and the gathering of expert opinions. An IPA (Importance Performance Analysis) analysis is conducted to identify problems and suggest promoting policies for the Yeosu Port cruise industry. According to the IPA analysis results, in the major categories, the creation of cruise infrastructure, and the establishment of a support system were evaluated as weak items (high importance but low satisfaction), and sub-categories corresponding to the two major categories were identified as weak points. Based on the results of this analysis, measures to promote the cruise industry in Yeosu Port were presented as cruise infrastructure, route expansion, tourism product development, and support system. This study is expected to be utilized when establishing policies for constructing Yeosu Port as the hub port of maritime tourism in Korea.

The effective control of cost overrun is a crucial issue for construction companies to secure profitability. Especially in situations where cost pressures are significant due to factors such as rising raw material prices and increased financial costs due to high-interest rate policies, cost overruns resulting from project failures have a highly detrimental impact on the profitability of construction firms. The objective of this study is to analyze the current status of cost overrun control measures adopted by construction companies using the IPA technique and provide key characteristics and implications. The IPA analysis results showed that practitioners in general contractors exhibit a high level of interest and effort regarding cost overrun while the performance level is relatively low. Nevertheless, the measures considered important to control cost overruns generally show a high tendency for execution as well. Cost overrun control measures that show high importance but low execution are primarily related to collaboration and communication sectors. To effectively control cost overruns, enhancing collaboration and communication with construction supervisors/CM, headquarters, and regulatory authorities emerged as the most urgent need. Through this study, the current status and areas for improvement regarding cost overrun control measures in general contractors can be identified. This can be valuable for deriving directions and enhancements for future cost overrun control strategy development.

1. 서론 : 투과증발이란 비다공성 고분자막을 이용하여 수착, 확산, 및 증발기구를 통해 액체혼합물을 분리하는 기술이다. 따라서 투과증발의 분리효율은 고분자막의 종류 및 형태의 다양성뿐만 아니라 여러 단계의 기구 특성에 의해 결정된다. 일반저긍로 투과증발막의 성능은 분리하고자 하는 물질에 대한 선택도와 투과도로서 나타날 수 있다. (중략) 본 연구에서는 Poly(dimethylsiloxane)과 세라믹 지지체의 복합막을 이용하여 IPA(Isopropanol)/물 계에서의 여러 조업변수에 따른 IPA의 분리특성을 연구하였다.
