The global Covid-19 pandemic has been accelerating the transition to the digital environment that enables providing consistent services without being affected by physical location or various circumstances. The Metaverse might be the representative realization reflecting this trend. In this paper, we introduce the potential core stacks consisting of the Metaverse framework in brief and explain why the open Metaverse framework is an adequate and reasonable design choice to support diverse platforms and multiple instances of the virtual world. Since the development of the open Metaverse framework is indeed in a very early stage, achieving technical completeness in each building block of the open Metaverse is crucial. Considering the expansion and spread of the Metaverse in the future, intensive standardization studies on the open Metaverse framework are exigent and indispensable.

This paper presents a review of standardization activities toward the interoperability between different metaverse platforms, which is a research hotspot in the metaverse. The metaverse is often considered as the evolution of the current mobile Internet. Like for the Internet, interoperability is essential to provide continuous user experiences over different metaverse service environments. However, current metaverses have limitations in providing interoperability in terms of portability of services, digital objects, such as identity and avatars, and economic systems. To address these limitations, the metaverse industry and open-source communities have recently begin to develop metaverse interworking standards. We describe activities conducted by various representative standardization bodies such as the Metaverse Standardization Forum, W3C (World Wide Web Consortium) Open Metaverse Interoperability, Open Metaverse Foundation, Open Metaverse Alliance for Web3, and Metaverse Alliance. In addition, we discuss how to counteract interoperability issues from the Korean perspective.

Computer Integrated Manufacturing (CIM) is undoubtedly one of the most influential concepts to have been introduced into the manufacturing world in recent times. The successful CIM application is greatly depended on the way of the approach to given manufacturing environments. This paper reports a new approach in building CIM systems trough the development of a poen cell controller.

Recently, open source automatic machine learning solutions have been applied in many fields. To apply open source automated machine learning to real world problems, you need to write code with expertise in machine learning. Writing code without machine learning knowledge is challenging. To solve this problem, the automatic machine learning solutions provided by startups are made easy to use with a clean user interface. In this paper, we review automatic machine learning solutions of startups.

In this paper, we propose a direction for improving 'Geospatial information open platform' service to support the converged and integrated geospatial information. Since there can be a number of issues relating to the support for geospatial information convergence industry, two qualitative surveys were performed to collect opinions comprehensively and specifically. The responses from 165 experts from 5 areas that use geospatial information were used, and the requirements of demanders were divided into the aspect of policy, aspect of data development and distribution, and aspect of data utilization support in order to effectively analyze the survey results. As a result, a total of 26 major issues were derived and it was deemed that it is necessary to find a way to expand the role of 'Geospatial information open platform' from "Open-API Oriented Passive Spatial Information Open Platform" to "Platform that Comprehensively Provides Active Convergence Support Information" order to resolve the issues derived.

As open skies polices have permeated all over the world, Korea's basic direction of aviation policy is promoting the benefit of the public and the national carriers' competitive power by establishing open skies agreements between the countries. The open skies' directions should be promoted by considering the relationships of various attributes such as governments, airlines, and passengers. To decide the right directions of open skies, we should investigate the economic effects of open skies policies. This research develops a simulation model to analyze the dynamic characteristics of open skies. By using the developed model, this research analyzes the economic effects of open skies. The results showed that open skies have direct impacts on not only frequencies, airfare, consumer welfare but also air transport industry and regional economy. Therefore, it is necessary to take suitable aviation policy that can increase the effects of open skies.

Recently the environment in geospatial information has conversed into the plaform. The platform based geospatial information contributes to save time and cost as well as maintain the consistency and stability in spatial data infrastructure. The Republic of Korea is now constructing and operating the spatial open platform called as the V-World(Virtual World), and searching for the possibility of its abroad export. The purpose of this study is to elicit the abroad export strategy by country of spatial open platform by comparing the cases of developing country, the Kingdom of Cambodia and newly developed country, the Emirate of Abu Dhabi, The Kingdom of Cambodia depends on foreign aids to develop the spatial data infrastructure and the Emirate of Abu Dhabi is inducing an advanced technology and high human power from overseas based on abundant oil money. This study establishes the abroad export strategy based on two country models such as Cambodia and Abu Dhabi by considering the characteristics in geospatial information, and suggests the ways of abroad export and the methods on fund raising for spatial open platform.

The primary goal of this research is to link two currently disconnected literature; the history of urban redevelopment and the one of urban parks and open spaces in the United States (US). Through this exercise, this study attempts to reveal examples of urban parks and open spaces that have yielded economic effects, and emphasize their possibility as a measure of urban redevelopment. Five phases are presented, starting with two Pre-World War II urbanization periods, and three subsequent periods of Post-World War II urban redevelopment (1940s~1960s, late 1960s~1970s, 1980s~present). While urban parks in the 19th century urbanization period held a preeminent place in urban design, policy and economy, ensuing depression and World War II diminished their role as a channel to ease unemployment. In the first phase of urban redevelopment, the economic motive to build open space was to boost the appeal of specific locales in order to draw people and businesses back to a neglected city. In the second phase, public effort to create and maintain urban parks and open spaces declined due to the budget austerity, instead, community open spaces flourished through the voluntary actions and helped neighborhoods to regain desirability. In the third phase, the aspirations and functions of such projects resemble their forerunners of the first phase, but their targets extended to global businesses and elites.

Most of data objects in the real world have spatial and temporal information simultaneously. One of the objectives of spatiotemporal databases is to provide a very expressive framework for spatiotemporal database applications. The object oriented spatiotemporal model can manage spatiotemporal data efficiently because the model is able to store the complete history of any objects. Therefore, in order to handle the spatiotemporal data in object oriented fashion, we proposed a low dimensional spatiotemporal model in the object oriented fashion that extended dimensionally two dimensional spatial model of OpenGIS to fit into the real world information and to include temporal information. In order to proof the proposed model, we design a data provider component which consists of the data source, the session, the command, and the rowset component, and implement it. The proposed four dimensional spatiotemporal data model and provider in the object oriented fashion can be used to store, retrieve and manage the object oriented spatiotemporal data.
