After enforcing 2007 semi-public management system of intra-city bus, Busan city has tried to promote the bus utilization through bus service improvements. As an effort for this, we attempted to clarify the main factors affecting to bus service satisfaction targeting intra-city bus users. In this study, 20 subcategories of intra-city bus service were assorted into 6 factors: Basic Service, Safe Driving, Route Information, Comfort, Cleanliness and Facilities, then the preference for each detailed bus service were analyzed. And the effects for bus service satisfaction were shown under the various conditions according to the general characteristics of intra-city bus users (gender, age), behavioral traffic characteristics (frequency of use, boarding time) and transportation environments (temperature, rainfall). These results would be important basic data for decision-making in bus policy for climate change and establishment of operating plan for bus utilization.

Due to its intrinsic characteristic, exterior bus advertising is exposed to an unspecified number of the general public. Thus it influences on the urban publicness of the city, simply beyond leaving it as a personal marketing activity toward the industry's profit. Seoul city's campaign to improve exterior bus advertising has been to effective in removing advertisements of alcohols, tobaccos, and lascivious contents, however, there still are several advertisements that should be examined from the view point of publicness. For the case of UK, where exterior bus advertising is also actively utilizing owing to its high exposure and effectiveness, they are administrating it by setting up guidelines and regarding the importance of publicness. I also identified the meaning of publicness of exterior bus advertising from the aspects of 'publicness of territories', 'publicness of subjects', 'publicness of reasoning', and 'publicness of procedures'. Through this, I suggested that both commercial right of exterior bus advertising in the private sector and citizen's right of publicness can be harmoniously developed by properly controlling and administrating the exterior bus advertising. Furthermore, artistic approach to the exterior bus advertising from the viewpoint of city environment is expected to elevate the aesthetic possession and the level of design sense of citizens.

Many studies on bus scheduling optimization have been done from the 1960s to recent years for establishing rational bus schedule plan that can improve convenience of bus passengers and minimize unnecessary runs. After 2000, as part of the Intelligent Transport Systems (ITS), the importance of the schedule management and providing schedule information through bus schedule optimization has become a big issue, and much research is being done to develop optimization models that will increase bus passenger convenience and, on the side of bus management, minimize unnecessary bus operation. The purpose of this study is to calculate the optimal bus frequency and create a timetable for each bus stop by applying DTR or DTRC model that use data for each bus stop and route segment. Model verification process was implemented using data collected from bus management system (BMS) and integrated transit-fare card system for bus route of Seoul's No. 472 line. In order to evaluate the reliability and uncertainty of optimal solution, sensitivity analysis was implemented for the various parameters and assumptions used in the bus scheduling model.

It raises questions about how China, dominated by the socialist system and the Communist Party, will change in the era of artificial intelligence. We predict how the Chinese socialist system will change in the meta-world where SNS is developed, communication is conducted within the meta-verse world, and artificial intelligence is operating in many fields. In order to do so, it is necessary to understand the characteristics of the Chinese state and the characteristics of national policy, as well as the metaverse policy proposed by the Chinese state. The development of the metaverse was emphasized at the 5th session of the 13th National People's Congress in 2022, and in May of that year, the Central Party School of the Communist Party of China published the <Metaverse Industry Manual for Party and Political Officials>. Therefore, in this paper, we will analyze China's metaverse policy and forecast the direction of development of the metaverse industry that China wants to pursue.
