This study had been carried out based on the users' behavioral pattern in order to survey characteristics of bus station, a public facility. As a detailed analysis, quantification theory type 3 was performed based on 50 number of samples installed at each local governments as targets in order to evaluate bus station attributes and to survey its characteristics. As a result of this experiment, it was revealed that installation pattern of bus station would differ depending on characteristics of four axis of migrating population density, functionality and simplicity, metropolitan city of densely populated companies, local city with strong locality, the front of school with dense migrating population, secluded rural village, specific place like museum, rural area with dense migrating population. Therefore, in this study, detailed items were suggested comprehensively so that the design considering local environment and users' characteristics, in addition to modeling features of bus stations suitable for local characteristics, could be progressed. If any design and model complying with local environmental features based on above contents should be applied, bus station would be assessed by the users more positively in the future.

Digitalization of the substation in Korea has been in progress so far with focusing on Station Bus. However, its application to Process Bus has been delayed due to some technical issues. IEDs based on Process Bus use the data values of SV and GOOSE. As the size of communication data on Process Bus is comparatively bigger than that of Station Bus, it is very important for the evaluating the performance of Process Bus to analyze the transferring speed and quality of data from the first equipment, which is located on process level, to station level. According to the results of related studies, it is said that the most important factor for the design and operation of Process Bus network is the communication delay with consideration of the volume of packets. In the paper, the results of performance test for the network with and without application of VLAN on Process Bus system that uses integrated IEDs are presented. Additionally, the paper proposes the optimal method to analyze the communication delays of network systems through evaluating the maximum delay time, link process ratio and the amount of lost packets by using a simulation tool.

This paper deals with the implementation of the IEEE 802.4 token passing bus protocol which is the world standard for LAN protocol. We are design station adaptor using MC68824 for data link layer, MC68194 for physical layer, and implemented by IEEE 802.4 and 802.2 type 3. We made three station adaptor and its performance is experimented.

Soundscape design is applied for the purpose of expressing the characteristics of places, by supplying suitable background sound for various places expressing their identity. Bus stations are a place for aggregating people using transportation. That is, people go into a station, buy a ticket, and wait for departure or for other passengers. Therefore, they need to create a more comfortable sound environment. This study aims to make bus stations a comfortable place acoustically for users. In this study, analysis on behavior at various locations in the space was performed. Measurements were taken on the approaching path, waiting place, departure and arrival platforms for sound levels and frequency characteristics. In addition, on acoustic specialists evaluation, using questionnaires, was also performed ambient noise, information broadcasting and users dialogue.

This study supplements the existing bus information system's weakness which is a text-based system, transmits GUI based user request contents, design and implements the bus information system using smart-phone GPS. The existing bus information system had to install the terminals on the bus and take enormous expenses on maintenance with setting up the direction board on each bus station. The proposed system provides bus route and user location using the smart-phone map screen, finds the nearest bus station, indicates the bus route on map screen, applies our algorithm which increases accuracy of the bus arriving time, and provides route construction of the inner-cycle bus. The accuracy of the estimated bus arriving time has increased to about 88.71% which is 22.71% more than the existing system whose accuracy is 67% and improved into GUI form that the existing system was on text and table UI. Consequently, the upgraded bus information system uses the smart-phone GPS to supplement the existing bus information system and satisfies different requests of users.

This design study was conducted to plan and propose the bus-station as the public design for Cheongju City. The study was provided other purposes which designed its function as plant container and revealed the brand identity of Cheongju City, Jikji. At planning stage, design plant container with motif from top roof of the Early Printing Museum of Cheongju. And planed it located on the top of facility. The facilities, with design factors that increase satisfaction, were planed through the analysis of user behavior. The narrow frame and transparent wall were intended to establish clear sight for its users or pedestrians on road. In order to harmonize with urban surroundings, decreased the fanciness of designed figure and used achromatic color as lead main color.

Considering the number of population commuting from Gyeonggi to Seoul, the development of the bus system is relatively slow. There are many problems to be solved but it has been overlooked, leaving the users in discomfort. The goal of this research is to improve the current system to satisfy the unmet needs, using HCI methods, which is composed of five steps, including Define, Find, Analyze & Synthesize, Ideation, Develop. In Define, we recruited the interviewees using the extreme user method to find their needs. In Find, we proceeded 'be the customer', shadowing for background research and in-depth interview. In Analyze & Synthesis, we analyzed the customer needs and clustered to similar needs to draw useful ideas. After that we suggested sophisticated ideas based on design principles from previous stage and visualized in user scenarios and mock-ups. Overall, the research suggests with text message service, informative light service and mobile application to improve the existing bus station.

In recent years, many researches for DC power distributed system (PDS) are being preformed and the importance of the DC PDS is more and more emphasized. Furthermore, in the railway system, the DC PDS is used in subway station lighting, facilities, etc. In the DC PDS, DC bus voltage instability may be occurred by the operation of multiple parallel loads such as pulsed power load, motor drive system, and constant power loads. Thus, good quality and high reliability for electric power are required and voltage bus conditioner (VBC) may be used the DC PDS. The VBC is a DC/DC converter for mitigation of the bus transients. In this paper, adaptive controller is designed. The simulation results by PSIM are presented for validating the proposed control algorithm.

Most of people still use the bus, which is one of transportation. But the space of cauch station where the passengers wait for the bus is still not enough for them in effect. Therefore, the space is analyzed through looking into the behaviors occurred in the waiting space .So, this paper defines the a primary factor affecting environmental from the existing environment and experience behaviors occurred in the existing environment, and suggests design guideline based on data and information from the result when redesigning.
