The purpose of this study is to present practical implications for employment of people with developmental disabilities by analyzing the moderating effect of family employment support in the relationship between discrimination experience and employment of people with developmental disabilities. The subjects of the study were 394 people with developmental disabilities who participated in the 2nd wave 4th survey of the 2019 Employment Panel Survey for the Disabled, and a hierarchical binary logistic regression analysis was conducted to verify the hypothesis. As a result of the study, it was found that the experience of discrimination among people with developmental disabilities negative effects employment, and family employment support has a significant moderating effect, strengthening the negative effect of discrimination on employment. Therefore, the importance of improving the working environment reflecting the needs of families with developmental disabilities, the necessity of employment support policies, and strengthening trust with the state and local communities were discussed.

Most of the preceding studies related to Internet Primary banks are studies on laws, regulations, and expected effects of introduction, and studies on financial consumers' intention to switch to financial services are insufficient. Apply to the PPM(Push-Pull-Mooring)theory to find out the factors that influence financial consumers' intention to switch services from commercial banks to Internet Primary banks. A survey was conducted service users, 1st-order and 2nd-order factor analysis were performed using Smart PLS 3.0. As a result, it was confirmed that the Pull, Push and Mooring had a positive (+) effect on the Intention to Switch, and the Mooring, which is a moderating variable, did not have a moderating effect on the Intention to Switch of the Push and the Pull. The scope of application of the PPM theory, which was used in the service conversion research, was extended to Fintech services, and it can provide various practical useful implications, such as the strategy and spread of Internet Primary banks, and it will be used in various studies to study consumer attitudes.

This study proposes a distributed parallel processing system, called the Fast Analysis System for remote sensing daTa(FAST), for large-scale satellite image processing and analysis. FAST is a system that designs jobs in vertices and sequences, and distributes and processes them simultaneously. FAST manages data based on the Hadoop Distributed File System, controls entire jobs based on Apache Spark, and performs tasks in parallel in multiple slave nodes based on a docker container design. FAST enables the high-performance processing of progressively accumulated large-volume satellite images. Because the unit task is performed based on Docker, it is possible to reuse existing source codes for designing and implementing unit tasks. Additionally, the system is robust against software/hardware faults. To prove the capability of the proposed system, we performed an experiment to generate the original satellite images as ortho-images, which is a pre-processing step for all image analyses. In the experiment, when FAST was configured with eight slave nodes, it was found that the processing of a satellite image took less than 30 sec. Through these results, we proved the suitability and practical applicability of the FAST design.

The goal of this study is to examine the impact of time perspective and life satisfaction of government and public institution employees on organizational SNS attitude and word-of-mouth effect. A total of 136 incumbent employees participated in this online survey. It was found that past-positive, present-hedonistic, and future time perspective positively affected life satisfaction and the organizational SNS attitude. Meanwhile past-negative time perspective negatively affected life satisfaction only, present-fatalistic time perspective did not negatively affect life satisfaction and organizational SNS attitude. Finally, life satisfaction showed a positive impact on word-of-mouth effect via organizational SNS attitude. By identifying psychological underpinnings of time perspective and life satisfaction, this study will provide theoretical and practical implications regarding internal communication and the effective management of government and public institution-operated SNS.

It is necessary to understand the amount of snowfall and area of snow cover of Mt. Halla to ensure the safety of mountaineers and to protect the ecosystem of Mt. Halla against climate change. However, there are not enough related studies and observation posts for monitoring snow load. Therefore, to supplement the insufficient data, this study proposes an analysis of snow load and snow cover using normalized-difference snow index. Using the images obtained from the Sentinel2 satellite, the normalized-difference snow index image of Mt. Halla could be acquired. This was examined together with the meteorological data obtained from the existing observatory to analyze the change in snow cover for the years 2020 and 2021. The normalized-difference snow index images showed a smaller snow pixel number in 2021 than that in 2020. This study concluded that 2021 may have been warmer than 2020. In the future, it will be necessary to continuously monitor the amount of snow and the snow-covered area of Mt. Halla using the normalized-difference snow index image analysis method.

The purpose of this study was to develop evidence-based practice guideline for rapid response to acute deterioration of hospitalized patients. The guideline was developed according to the Clinical Practice Guideline Adaptation Manual. and evaluated using AGREE II tool. The guidelines were checked content validation by an expert group, final 130 recommendations in 5 sections including management, recognition, activation, response, and evaluation. The average of the overall practical application to the guidelines was 4.41±0.78 out of 5, which showed high applicability in clinical work.

The purpose of this study was to explore the various data and methods employed by HR analytics studies. The researchers selected 78 KCI-indexed empirical articles on HR analytics and categorized them using the Employee Life Cycle framework. This yielded several important findings. First, employee retention has been the most common subject of extant studies, followed by performance management. Second, HR analytics studies have used a variety of data (structured and unstructured) according to their research questions, and the data sources have ranged from organizations' internal systems to national databases. Third, most domestic HR analytics studies have been descriptive and diagnostic, whereas predictive and prescriptive studies have been rare. These results have important theoretical and practical implications for future HR analytics research.

The present study explored the moderating roles of perceived responsiveness of SNS friends and self-esteem in the relationship between SNS use and perceived social support among college students. Using a panel owned by a research firm, a nationwide online survey was conducted (females N = 264, males N = 239). The results of regression analysis suggested that there is no significant main effect of SNS use but a significant main effect of perceived responsiveness of SNS friends. In addition, a three-way interaction effect was found among perceived responsiveness of SNS friends, SNS use, and self-esteem. This study contributes to elaboration of the extant research as well as providing practical implications to SNS-based intervention programs for college students' psychological well-being.

The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.
