This study aims to study the effect of service quality of lifelong education in culture and arts on educational satisfaction, intention to continuous use and performance. The service quality of culture and art lifelong education was divided into three dimensions: education quality, administrative quality, and environmental quality. As detailed factors related to quality, six variables were set based on SERVQUAL: convenience, expertise, responsiveness, supportability, empathy, and tangibility. For this study, data were collected from 310 people taking cultural arts lectures at lifelong educational institutions in Seoul, Daegu, and Gumi. Since it was only for lectures related to culture and arts, a total of 256 materials were used for the study, excluding inappropriate materials. A structured questionnaire was used as a data collection method, and a structural model analysis was conducted to verify the hypothesis. As a result of this study, responsiveness among the service quality factors of lifelong education for culture and arts was rejected. In addition, the higher the satisfaction with the culture and art lifelong education institution, the higher the performance and the intention to continue using it. The theoretical and practical implications of this study result were discussed, and future research tasks were presented.

In December 2019, the Ministry of Land, Infrastructure and Transport announced the revision of the Enforcement Decree of the Industrial sites and Development Act. In this revision, the reinvestment ratio of development profits generated by renewing the old industrial park is delegated to the local government ordinance. According to this announcement, the reinvestment ratio can be adjusted to less than 50% of sales revenue from construction projects and 25% of land sales for non-industrial use depending on local government conditions. This study aims to investigate the policy rationale for the adjusted ratio of reinvestment in development profits and explore how Daegu City can use this policy when revising ordinances in the future. A survey was conducted with a total of 320 experts, including public corporations, public officials, and industrial site workers in the Industrial Complex Committee. We employ contingent value measurement (CVM) based on 262 valid responses. The results showed that 27% of sales from the construction business and 22% of sales from non-industrial land were derived with an appropriate reinvestment ratio. Although the results in this study might not be generalized in other regions, we provide a potential reference for other local governments who are interested in ordinance revisions in the future. Another contribution of this study is to suggest the statistical method to derive the relevant ratio.

This study was conducted with the aim of developing a mobile app so that parents and children can provide questions and conversation-based Home Humanity Education. App development was developed in four stages: analysis, design, development, and evaluation by modifying the ADDIE model. In the analysis stage, education goals were set and seven core competencies were extracted for the app. In the design stage, 15 menus, including character to implement seven core competencies, were selected for learning contents. In the development stage, questions were asked based on 1,000 photos, and parents and children naturally talked to strengthen their core competencies. In the evaluation stage, the user's evaluation interview was followed by a reflux process that produced and reflected improvements. Based on research results, it is going to suggest follow-up research on developing apps for home humanity education. First, it is necessary to verify the learning experiences and changes that occur when parents and children use apps for a long time through longitudinal research. Second, a follow-up study is needed on how to use the home humanity education app by age and how to improve it accordingly. Third, as the number of cases in which grandparents raise their grandchildren increases, it is necessary to study the process and learning effects of grandparents and grandchildren using the app.

The purpose of this study is described in detail as follows. First, I would like to define what digital transformation is in the maritime transport sector. Second, it is intended to derive success factors for digital transformation in the maritime transportation field by examining various preceding studies related to digital transformation. Finally, in order to derive priorities for the derived success factors, an AHP analysis model is built and an expert survey is conducted for practical experts in the maritime transportation field. Based on the survey results, we would like to provide guidelines on what factors should be considered first among the success factors of digital transformation in the maritime transportation sector. In this study, in order to derive the priority of success factors for digital transformation in the maritime transportation field, the hierarchical structure was divided into four high-level evaluation items(strategic factors, organizational culture and human factors, technology factors, and environmental factors) and 21 sub-evaluation items. A relative evaluation method of weighting items among AHP(Analytic Hierarchy Process) was applied. AHP analysis of 24 questionnaires with a consistency ratio of 0.1 or less in order to increase the accuracy of information among questionnaires collected through maritime transportation related university professors, research groups, shipping companies, container terminals, and experts engaged in shipping related IT companies was carried out. As a result of the analysis, the priority of the first-tier factors for the success factors of digital transformation in the maritime transport sector was shown in the order of strategic factors, organizational culture and human factors, technology factors, and environmental factors. In addition, when looking at the priorities of 21 detailed items, it was found that the development of new business models, the creation of an active future digital strategy, and the leadership of the chief digital officer were high.

In this study, each component of flow noise source of underwater propeller installed to the scale model of the KVLCC2 is investigated and the effect of each noise source on underwater-radiated noise is quantitatively analyzed. The computation domain is set to be the same as the test section of the large cavitation tunnel in the Korea Research Institute of Ship and Ocean Engineering. First, for the high-resolution computation of flow field which is noise source region, the incompressible multiphase Delayed Detached Eddy Simulation is performed. Based on flow simulation results, the Ffowcs Williams and Hawkings integral equation is used to predict underwater-radiated noise and its validity is confirmed through the comparison with the tunnel experiment result. For the quantitative comparison on the contribution of each noise source, the spectral levels of sound pressure and power levels predicted using propeller tip-vortex cavitation, blade surface and rudder surface as the integral region of noise sources are investigated. It is confirmed that the cavitation which is monopole noise source significantly contributed to the underwater-radiated noise than propeller blades and rudder which is dipole noise source, and the rudder have more contribution than propeller blades due to the influence of the propeller wake.

Safety education delivered to construction workers in a lecture manner has limitations in concentration and immersion, so delivery power and interest are low. In order to improve unstable behavior through education and prevent safety accidents, it is necessary to change the paradigm to hands-on education. Purpose: Experiential safety education aims to contribute to preventing accidents for construction workers by quickly recognizing risks, improving emergency response skills, and verifying the effectiveness of pre- and post-learning. Method: Based on a survey of workers who experienced the same work environment as the actual construction site, an opinion survey on the pre- and post-safety experience education and a variable measurement tool were planned, and a research hypothesis was established. Results: The Bayesian theory and MC simulation analysis were used to analyze the structural equation model, and the change in construction worker behavior was confirmed through the intended safety (A), non-experiential education in the sub-area of anxiety (B), average, standard deviation, and minimum and maximum values. Conclusion: The effect of education and industrial accidents are reduced only when construction workers are motivated to participate.

오늘날 대다수의 선진 국가들은 고령화 사회에 대비하여 자국의 노후소득보장 제도를 대대적으로 개혁해 오고 있다. 우리나라의 경우에서도 지난 2015년 사학연금제도의 개혁이 이러한 취지에 해당될 수 있을 것이다. 본 연구에서는 고령화 사회의 문제가 단순히 노인부양비용의 증가 그 자체가 아니라, 평균수명의 증가에도 불구하고 늘어나게 된 노후의 삶에 대한 시간적 배분이 근로와 여가에 걸쳐 균형적으로 이루어지지 않고, 사회적 부양을 필요로 하는 노후의 여가만 일방적으로 늘어나고 있다는 점을 문제점으로 지적하였다. 따라서 이러한 차원에서 볼 때 고령화 사회의 문제는 생애근로기간의 연장을 통해서만 효과적으로 극복할 수 있을 것으로 생각된다, 하지만 이와는 반대로 개인별로 건강상태나 가족상황 등의 이유로 생애근로주기의 연장이 불가능한 사람들을 위하여 별도의 제도적 장치가 추가적으로 마련되어야 할 것이다. 종합해 보면, 고령화 사회의 노동시장 문제는 개인별로 다양한 욕구나 능력을 반영하여 각자에게 다양한 선택권을 보장해 줄 수 있는 방향으로 개선되어야 할 필요가 있다. 본 연구에서는 고령화 사회에 대비하여 연금수급연령 상향조정의 필요성을 사학연금제도를 중심으로 살펴보고, 대신 그로 인해 발생할 수 있는 소득공백문제와 연금가입경력 공백문제 등 제반의 충격을 흡수할 수 있는 제도적 장치로서 점진적 퇴직제도의 도입방안을 제안하였다. 개략적으로 사학연금제도에 있어서 점진적 퇴직모형은 법정연금수급연령의 인상 일정에 따라 다음과 같이 운영하는 방안을 제안하였다. 먼저 법정연금수급연령이 60세로 유지되는 2022년까지의 단기적 대책으로서 여기서 점진적 퇴직의 자격연령은 모든 가입자에게 60세로 적용하도록 한다. 이 경우 가입자들의 신분구분에 따라 각각 교수 5년, 교원 2년(문제해결에 대한 정책적 의지에 따라 이행구간을 확장할 수도 있음) 그리고 교직원 0년의 조기의 점진적 퇴직이 허용되므로, 현재 교원이나 교수의 임용대란문제에 효과적으로 대응을 할 수 있는 장점이 있다. 다음으로는 2023년 이후 2033년 사이 법정연금수급연령의 인상단계에 해당되는 기간 동안의 대책으로서 여기서는 교수, 교원, 교직원에게 적용되는 정년연령과 매년도 법정연금수급연령 사이의 기간을 조기의 점진적 퇴직 이행구간으로 정하도록 한다. 그리고 이러한 이행구간에 상당하는 기간만큼 후기의 점진적 퇴직 이행구간을 별도로 설정하여 그에 적절한 혜택이 주어질 수 있도록 한다. 마지막으로 2033년 이후부터는 교수, 교사, 교직원의 신분구분 없이 모두에게 적용되는 사항으로서 65세를 기준으로 그 이전의 5년은 사학연금의 적용을 받는 조기의 점진적 퇴직 그리고 그 이후의 5년은 국민연금의 적용을 받는 후기의 점진적 퇴직이 이루어질 수 있도록 한다. 그리고 전체 10년의 점진적 퇴직 이행구간 동안 개인별로 퇴직시점이나 퇴직형태의 선택이 자유롭게 이루어질 수 있도록 하기 위하여 보험수리의 원칙에 입각한 감액률 또는 가산율의 엄격한 적용을 제안하였다. 그리고 고령계층이 자신의 근로시간을 단계적으로 단축할 수 있도록 하고, 그 과정에서 발생하게 되는 소득의 감소부분은 별도의 제도적 방법(가교연금, 시간가치적립계정 등)으로 충당하도록 하는 방안을 제안하였다. 나아가 점진적 퇴직제도의 운영방식은 근로시간의 단축뿐만 아니라 작업부담의 경감 등에 대해서도 인정을 해주도록 해줌으로써 임금피크제도의 기능과 연계가 가능할 수 있도록 할 것을 제안하였다.

The existing mass transport system, with its limited capacity and the saturated road networks, has given cause for a new means of transport to be developed, and strong demands for such new means of transport are observed more than ever. However, the traffic authority is seeking a new transport system that focuses more on LRT(Light Rail Transit), a downsized version of the existing urban railroad, rather than one that is appropriate to solve the traffic problems. Moreover, local governments are experiencing difficulties in planning their own mass transportation(bus or urban railroad) as they have no specified criteria for selecting a mass transport system. Accordingly, there has been an increasingly loud voice that calls for criteria to determine which mass transport system befits each transportation corridor. This paper develops a mass-transport demand forecasting model based on the GIS Buffering analysis of each transportation corridor in the city, sets up the capacity for each mass transport system and presents the criteria for selecting an optimal mass transport system for each transportation corridor. It also presents a methodology that identifies necessary and sufficient conditions for selection and evaluation, since it is most important to select the optimal mass-transport system that can meet the demand by each mass-transportation corridor.
