  • The purpose of this study is to design a proper evaluation method for analysing the safety management efficiency of coastal ship companies, and to verify these evaluation standards by applying them to a representative company. For this purpose, 5 evaluation items and 14 specific sub-evaluation elements have been determined after collecting practical opinions from a group of expert, which consisted of safety managers in passenger ship companies, public servants as a ship inspector, passenger ship operations managers, etc. Next, the safety management levels of 44 coastal passenger ship companies were evaluated using these standards. Finally, the validity of the proposed evaluation method was verified through comparison analysis between the evaluation results and the ratio of major marine accidents. It was determined that companies with low evaluation levels were saw more major marine accidents than other coastal passenger ship companies, spurring greater interest in safety management. In conclusion, evaluation standards allow coastal passenger ship companies to voluntarily assess their safety management level were established. The result can also be applied to analyse the operation efficiency of coastal passenger ship companies.

  • Recently, as the problem of the traditional on-site labor-intensive construction production method has been raised due to changes in construction work labor and site conditions, the OSC method is gradually spreading as an alternative to this. Even in apartment houses, the application of the PC method is expanding centered on the underground parking lot, but the high cost structure is a problem compared to the conventional formwork method. In this study, factors affecting the calculation of construction cost in the economic evaluation, which are the core of determining the construction method for apartment buildings, are derived through domestic and foreign literature review and expert advice, the importance was analyzed through an opinion survey targeting industry experts. The measures to reduce construction cost were mainly derived from the improvement of the design and manufacturing process. It is expected that the factors affecting the construction cost and improvement measures of the PC method derived from this study will serve as a direction for technology development to spread the application of the PC method for apartment houses in the future.

  • In domestic public construction, disputes are increasing due to differences among stakeholders regarding contract price adjustment. In particular, the actual cost-plus fee for overhead costs due to the schedule extension cannot be agreed upon at the administrative phase, and most of them seek judicial judgment. Thus, this study aims to propose a 'sufficiently satisfactory' alternative to reach an agreement before disputes in order to minimize disputes related to the calculation of additional overhead costs. To this end, this study proposes three alternatives based on the rate method. Firstly, when calculating additional overhead costs, it is not calculated as an actual cost-plus-fee method, but as a rate compared to direct labor costs among net direct costs. Secondly, the calculated indirect labor costs are compensated for up to the legal maximum of legal limit costs such as general management costs, profits and so on. Thirdly, it reflects overhead costs increased or decreased due to change orders. Risks were analyzed by collecting expert opinions on the proposed methods and applying actual cases. Finally, as a result of investigating the level of consensus for each stakeholder, it was confirmed that all stakeholders could agree regardless of the size of the company. The result of this study is expected to as a useful tool among stakeholders in the construction fields that can be able to easily agreed upon.

  • The purpose of this study was to explore the domestic and overseas home modification policies, and review the direction of domestic home modification policies to enable 'Aging In Place; AIP' and the competencies required of occupational therapist as and expert in home modification. In order to expand occupational therapy for domestic home modification and strengthen occupational therapist competency, it is required to establish a clear and practical home modification process that reflects the design and intervention of occupational therapy. Appropriate selection and standardization of the evaluation tools that identifies the needs of the elderly and reflects the characteristics of domestic housing types are also required. In addition, it is necessary to understand policies and systems, and endeavour to establish a relevant knowledge base for communication and cooperation with experts in other fields. In terms of the policy, there is a need for the home modification support system that allows the elderly to adapt to their aging regardless of their income level, beyond the existing support system, which was implemented mainly for low-income people and disabled. In addition, as in overseas cases, the efforts need to be made to provide various and efficient measures, such as support for barrier-free housing, expansion of the scope of support through cooperation between the national government and local governments, low-interest loans and tax reductions, and establishment of governance with organizations and institutions related to home modification services.

  • Teacher's gaze empathy for students in science class is considered to be effective in enhancing the learning effect. Thus, studies on gaze empathy have been conducted, but most of the studies are just to reveal the characteristics of gaze. Therefore, it is necessary to deal with a research to raise the level of science teacher's gaze empathy. The purpose of this study is to develop an instruction consulting strategy based on eye tracking for improving science teachers' gaze empathy. In this study, we selected and analyzed relevant literature on teacher's gaze empathy. We also designed a consulting strategy and then revised the design through expert reviews on validity and reliability. The developed consulting strategy was aimed to improve science teacher's gaze empathy and set quantitative goal based on eye tracking. The consulting strategy consisted of six steps: preparation for consulting, measurement and analysis of teacher's gaze empathy, instruction and feedback of gaze empathy, training for improving gaze empathy, evaluation of consulting result, and completion of the consulting. In addition, the consultation was completed or repeated again through the measurement and evaluation of gaze empathy using eye tracking. The developed consulting strategy has a value in that it provides an alternative with quantitative diagnosis and prescription for improving gaze empathy. The strategy can contribute to enhance teacher professional competency through the analysis of teaching behavior.

  • Cracks in bridges are important factors that indicate the condition of bridges and should be monitored periodically. However, a visual inspection conducted by a human expert has problems in cost, time, and reliability. Therefore, in recent years, researches to apply a deep learning model are started to be conducted. Deep learning requires sufficient data on the situations to be predicted, but bridge crack data is relatively difficult to obtain. In particular, it is difficult to collect a large amount of crack data in a specific situation because the shape of bridge cracks may vary depending on the bridge's design, location, and construction method. This study developed a crack detection model that generates and trains insufficient crack data through a Generative Adversarial Network. GAN successfully generated data statistically similar to the given crack data, and accordingly, crack detection was possible with about 3% higher accuracy when using the generated image than when the generated image was not used. This approach is expected to effectively improve the performance of the detection model as it is applied when crack detection on bridges is required, though there is not enough data, also when there is relatively little or much data f or one class.

  • Purpose: We aimed to identify collaborative disaster governance through the demand and supply analysis of resources recognized by nurses during the COVID-19 pandemic. Methods: We used a descriptive study design with an online survey technique for data collection. The survey questions were developed based on focus group interviews with nurses responding to COVID-19 and expert validity testing. A 42-question online survey focusing on disaster governance was sent to nurses working in COVID-19 designated hospitals, public health offices, and schools. A total of 630 nurses participated in the survey. Demand and supply analysis was used to identify the specific components of disaster governance during a pandemic situation and analyze priority areas in disaster governance, as reported by nurses. Results: Demand and supply analysis showed that supplies procurement, cooperation, education, and environment factors clustered in the high demand and supply quadrant while labor condition, advocacy, emotional support, and workload adjustment factors clustered in the high demand but low supply quadrant, indicating a strong need in those areas of disaster governance among nurses. The nurses practicing at the public health offices and schools showed major components of disaster governance plotted in the second quadrant, indicating weak collaborative disaster governance. Conclusion: These findings show that there is an unbalanced distribution among nurses, resulting in major challenges in collaborative disaster governance during COVID-19. In the future and current pandemic, collaborative disaster governance, through improved distribution, will be useful for helping nurses to access more required resources and achieve effective pandemic response.

  • Chronic diseases have been increasing recently as the average life expectancy of humans has been extended, and this trend has caused problems such as the widespread demand for health and rehabilitation services and rising medical costs. In order to solve this problem, the community-based rehabilitation has been developed and strengthened in Korea and gradually promoted since 2019. It is important to secure access to clients who want to use services to revitalize community-based rehabilitation. So in this study, as part of the community-based rehabilitation, intends to devise smartphone applications designs and develop a prototype to secure access to community-based occupational therapy services based on occupation and activities. For Occupational Therapy Practice Framework (OTPF), International Classification of Functioning, Disability and Health (ICF), and Allen Diagnostic Module-2 (ADM-2) were used to devise and categorize occupation and activity based application content, and link OTPF, ICF, and ADM-2 through prior research analysis and expert meetings. The derived content was visualized through literature review and activity analysis, and was implemented to enable direct playback within the application using the YouTube API, and finally developed a prototype application. The Android Studio 3.5.2 for Windows 64-bit was used to build the application prototype. In further research, converging various digital technologies for user convenience and additionally researching community-based occupational therapy service providers opinions and service user satisfaction will improve accessibility to community-based occupational therapy services for clients who have difficulty occupational performance in the community.
