We look at the rocket life stages of NaverZ's metaverse platform scaling and investigate the ignition and scale-up stage of its metaverse platform brand, Zepeto based on the Rocket Model (RM). The results are derived as follows: Firstly, NaverZ shows the event strategy by collaborating with K-pops, the piggybacking strategy by utilizing other SNSs, and the VIP strategy by investing in game and entertainment content genres in the 'attract' function. In the second 'match' function, based on the matching rule of Zepeto, the users can generate their own characters and "World" with Zepeto Studio. However, for strengthening the matching quality, NaverZ is investing in the artificial intelligence (AI) based companies consistently. In the 'connect' function, NaverZ's maximization of the positive interaction is possible by inducing feed activities in Zepeto & other SNSs and by uploading attractive content for viral effects in the ignition. For facilitating this, NaverZ expands the scale to other continents like Southeast Asia and Middle East with the localization strategy inclusive investment. Lastly, in the 'transact' function, based on three monetization experiments like Coin & ZEM, user generated content (UGC) fee, and advertising revenue in the ignition, NaverZ starts to invest in NFT platforms and abroad blockchain companies.

Internal and external conditions are currently changing-e.g, climate change increased awareness of energy crisis, and accelerated paradigm about green growth. Accordingly, revitalization of public transportation which enables green transportation system is receiving more attention than the past. Meanwhile, as the incom level increased, people required better quality of service, and consequently, various proposals about improving the services are being promoted. Generally, the quality of the spaces within transit in developed countries is represent the quality of life, thus concerns about the transit service of quality are emerging. This study, through the domestic and abroad studies about transit service quality, redefines transit service quality including rail and reviews the related categories. In that order this study deducts each type of evaluation categories and factors, with comparing and reviewing with various cases in Korea and overseas. Based on the whole process, the paper elicits implications and proposes to the research about the evaluation of transit quality of service.

Elevator industry is a field that is mechanical, electrical and electronic technology and constantly requires inspection and maintenance considering various applications and various types. Recently, various elevator control and monitoring technologies with IT are developing for elevators on land. But technologies with IT have been hardly done in marine elevator that is consistently assured safety and reliability of life cycle for its parts in poor environment. In this paper, we implemented embedded main controller, floor controller and car controller that meet the requirements and use NMEA network protocol by analyzing home and abroad integrated elevator operation and management systems. Especially, we secured reliability of maintenance by real-time fault diagnosis and control that was implemented with limit switch, gyro sensor, temperature/humidity/barometric pressure sensor and fire detection sensor thinking over the environmental conditions of terrestrial and marine elevator.

Studies on compensation structures of international technology licensing show that the level of intellectual property protection in the host market and the favorableness of the host country's economic environment are positively related to the use of running royalty-based compensation structure. Lump-sum fee or fixed royalty compensation is more likely to be used in the introduction and decline stages of the technology life cycle, and running royalty compensation in the growth stage. The international experience and the size of the licensor company are positively related to the use of running royalty. In this theoretical context, this paper analyzes the choice of compensation structures in Korean technology imports. The paper uses the officially reported data to analyze the compensation structures. It analyzes the characteristics of the compensation structures in terms of fixed royalty and running royalty by licensor country, group of licensor countries and size of licensee companies.

A reliability evaluation or prediction can be defined as MTBF which stands for mean time between failures (Exclusively for repairable failures). Spindle system has huge effect on performance of machine tools and working quality as well as is required of high reliability. Especially, it takes great importance in producing automobiles which includes a large number of working processes. However, it is unusually difficult to predict reliability because there are lack of data and research about reliability of spindle system. Standards and methods of examinations for reliability evaluation of machine tools are scarce at local and abroad as well. Therefore, this research is meant to improve the reliability of spindle system before mass produced with developing standards of reliability and methods of examinations through FMEA to assess reliability of spindle system in prototype stages of developing high speed spindle system of machining center.

The 21th century is rapidly turning to the era of supernational competition aimed at global customers. Under these circumstances, applying the value innovation to space which will be in charge of value creation is recognized as being essential to life. This study aims to newly define the conception, the viewpoint, and types on applying the value innovation to space, which has not been established logically yet. The purpose of analyzing cases where the innovation was applied at home and abroad is to provide basic logic to establish these concepts in real space design. This study is prospected to be the core strategy of growth cause for maintaining our industrial development, so it is suggested that accepting, widening, and developing it may enable us to prepare for the continued innovation to space.

The home network, contributing to improve the quality of life in dwelling, has expanded its installation and use in past years, but the elderly care system supporting self-reliance is not fully prepared. Although the aging society in Korea is progressing rapidly, inducting and spreading home network system is still required supporting of 'Aging in Place' for the elderly. This research is based the survey of spatial characteristics of housing of the elderly. Also, the research studied the technical level and policy of home network in domestic and abroad and analyze the professional view of experts in the home network field, as a result, suggested methods of building and activating the home network system.

With the advent of 21st century, the economic and cultural value of the tourism became more important than ever. And many countries have been aware of the importance of it and trying to promote it. In the railway industry, the sightseeing train is the most crucial element. It can be used as a means of transportation for the tourism or can be the objective of the tourism itself. The sightseeing train can contribute to improve the level of the national leisure life, to fill the cultural gap among the regions, to make foreign exchanges, or to accelerate cultural exchanges among countries. So, I would like to present some guidelines on the development of the sightseeing train through the research on the sorts, the designs and the services of the sightseeing trains operated in Korea or other countries.
