Recently, metaverse technology is being used in various service industries such as games, entertainment, manufacturing, distribution, advertising, and education. Studies on the correlation between the continuous use of devices used in metaverse content are still insufficient. In order to be more immersed in the metaverse, it is necessary to develop a natural movement and an easy-to-use input device. Based on flow, this study was conducted on the topic of continuous use of metaverse contents and devices. The constituent factors of Flow, an independent variable, were set as sense of reality, immersion, and interaction. We intend to use the data of 500 male and female metaverse users for research through a survey institution. Among the flow factors that increase the continuous use of metaverse contents and devices, the factors that have the greatest influence were studied. Through the results of this study, it is intended to help establish the direction of the next-generation metaverse content and device industry.

In this study, several important aspects were studied in producing video advertisements based on the lifestyle and SNS status of Generation Z. Generation Z highly values participation and interaction due to the nature of SNS, so SNS advertisements should be produced in a way that induces active interaction with viewers and accepts feedback. Here's a summary of the main parts. It prefers various content formats of Generation Z that consume information. Advertisements should be produced in various formats such as text, images, and videos, and should have flexibility suitable for various platforms. Because each SNS platform has its own characteristics due to platform specialization, this study suggests that advertisements analyze the characteristics of the platform and use the appropriate content strategy for the optimized platform. As an emphasis on value proposition, we propose an advertising format setting to focus on what value the product or brand provides. It is important to clearly emphasize the advantages and intrinsic value of a product or service in video advertising, and in conclusion, we propose to focus on the case of increasing interest by adopting modern and trendy design of storytelling as an attractive and unique design method of aesthetic design and visual effects. Considering these factors comprehensively, the research value of this paper will be able to establish an effective SNS marketing strategy by producing video advertisements that match the lifestyle and SNS usage characteristics of Generation Z.

In order to improve user accessibility and interactivity, system scalability, service speed, and a non-standard internet web environment, we developed a Web-based geovisualization system of oceanographic information using HTML5 and dynamic particles. In particular, oceanographic and meteorological data generated from a satellite remote sensing and radar measurement and a 3-dimensioanl numerical model, has the characteristics of a heterogeneous large-capacity multi-dimensional continuous spatial and temporal variability, based on geographic information. Considering those attributes, we applied dynamic particles represent the spatial and temporal variations of vector type oceanographic data. HTML5, WebGL, Canvas, D3, and Leaflet map libraries were also applied to handle various multimedia data, graphics, map services, and location-based service as well as to implement multidimensional spatial and statistical analyses such as a UV chart.

The study aims to determine whether SNS Usage has significantly influence on local administration PR. With the advance in information and communication technologies, many administrative organizations began to work in public relation to their residents via SNS. Nowadays SNS is transforming practical standpoints from forming public opinion through communication message to forming relationship with their residents. Therefore the needs to identify the relationship of the administrative organizations and their residents are demanded with the needs to investigate impact levels of SNS use on the relationships. While there are many researches to simply identify the features of SNS and to introduce local administration, the research investigating the sequential impacts of SNS use on local adminstration PR does not exist. The study targeted a borough office and its residents and compare those two groups. Findings illustrate that the SNS usage of administrative organizations suffer from the shortage of resident's feedback. Finally the study recommends the various issue developments to strike chord with their residents to utilize SNS use in local governmental organizations.

Despite a recent increased nation's attention given to improving end-life care, we professionals need to be more critical and reflective on our realities surrounding hospice palliative care. The aim of this paper is to suggest that palliative care models can be used for patients/families in the last phase of life and examine whether they are appropriate for caring them in congruence with philosophy of hospice. The hospice experience model (HEM) of Eagan & Labyak and the developmental model of Byock are introduced and examined for their congruence with philosophy of hospice in applying to clinical practice. The HEM as a patient/family value-directed end of life care model emphasizes three principles; unique experience of patient/family, interactions/relationships among multiple dimensions of personhood and between family, and personal growth and development in the face of suffering through a life-completion. The developmental model stipulates dying as the last stage of living, a stage of life cycle in which patients/family may have growth through life-completion in multidimensional relationships of personhood. The model includes the developmental landmarks and tasks for life-completion as the framework to guide a means of professionals' to recognize their opportunity to grow. The landmarks and tasks include worldly and social affair, individual relationships, intrapersonal, and transcendent dimension. The models could work as appropriate palliative care models for patients/families in the last stage of living. The professionals need to be encouraged to apply the models to end of life care setting.

ATM is a key technology of integration of multimedia service. Recently, Many study have been concentrated on performance testing for evaluation network performance are stronger everyday. The performance testing is on evaluation of maximal throughput of network by measuring and analyzing of various performance parameters. There are two ways to test ATM network performance; one is using QoS in cell level on the point of network's view, and the other is using metric in frame level in the point of user's view. And, the standardization process is also under way. In this paper, we derive a performance requirement of TCP in TCP/IP data transmission over ATM UBR service. By applying the derived requirements to ATM and packet networks, we evaluate the performance of TCP over UBR based on the result of our simulations. Therefore, we evaluate the result of simulation and find degradation of network throughput by interaction between TCP congestion control and ATM cell drop policy. So we suggest the accelerated Vegas that modify traditional TCP Vegas in congestion control mechanism for batter network throughput.
