The purpose of this paper is to find out and discuss architectural factors for planning the cultural facilities for performing art. For the purpose, the Culture & Art centers in major cities are investigated. The investigation focuses on the analysis of efficient utilization and spatial composition of the Culture & Art centers. Generally the cultural facilities must be located on the site where people can easily access, and should have various kinds and sizes of rooms which people can use for various activities. However, most of the investigated Culture & Art centers are apart from the downtown of the cities, and do not provide the varied spaces. In particular, the sizes of performing halls are too large, and this makes the ratio of room use frequency and the occupancy of seat to be low. To encourage people to use the Culture & Art Centers, the program managers should arrange various programs which reflect the needs of people, and the clients and designers should decide proper room sizes and functions through appropriate analyses of the facilities.

Today the design is recognized as indispensible part in business activities and it is demanded as one of the management strategies. since the ultimate goal of a hotel lines in the pursuit of profit, it is important that the design of a hotel faithfuly reflects the demands of management at the time of its construction planning. Furthermore, hotel planning undergoes a complicated design phases on a large scale, thus, utilization of a design process that accomodates retional approaches scientific and structural design activities, which will further reduce errors in design steps and pave a way for effective attainment of the target. Especially the management and designers review and confirm the design in relation to the strategic manegiable objective sat the early basic stage. The baseline set here will serve as a direction for the detailed design. In this context, this thesis formulates a reference baseline in dividing the space in view of the overall profitability and is based upon a survey conducted on the correlation between the operation of food and beverage section and the space. First, downtown hotels now take on the role of a public facility to a great extent and the number of Koreans who visit the autxiliary facilities of hotel increases. Second, recently revenue from a food and beverage section is in downtown and the trend is especially obrious at western restaurant, buffet and bar. This necessitates the reevaluation of the business space allocation. Third, sales promotion plan includes diversification, dessection and scaling down of the food and beverage section areas, Fourth, a proper number of seats must be determined in regard to the average area of one seat shown in the survey. Fifth, dense seat arrangement would entail a curtailment rather than a hike in revenue. Sixth, the installation of private dining room is on the rise and in particular, in Japanese and Chinese restaurants. Seventh, business space with declined revenue tends to induce the integration of similar businesses.

This study analyzed the characteristics of Physical Environment of existing free shuttle bus Interior centered on elderly people who frequently use free shuttle buses. The purpose of this study is to provide basic data that can be used for improvement of existing free shuttle buses. In the case of the old type, in terms of accessible design, the middle entrance is not normally opened except the wheelchair occupant, so that the entrance of the front wheel is always used. Therefore, most elderly people go to the back seat and travel distance is twice longer. In addition, many stairs caused frequent inconveniences for boarding. In the case of the new type, it is planned to be a low-floor type, and various types of safety rods and handles, pictograms for enhancing the information convenience are well-equipped, and the measured value of the overall design characteristic is high. However, in the case of mental stability, it was confirmed that the seat of the bus is colored with a cold color system and is in a different relationship with the warm color which can feel mental stability. Overall, both old and new shuttle buses lack audiovisual feedback on bus routes and route guidance in terms of Supportive design. Also, since the cleaning tools and other miscellaneous items were left in the room, it became an obstacle to space utilization in terms of adaptable design. In terms of safety, both shuttle buses did not come into view with fire extinguishers shaded by miscellaneous items. Therefore, immediate action is unlikely in case of emergency. This problem should be resolved quickly.

There exist a number of studies pertaining to the determinants of customer satisfaction between low-cost and full-service carriers in the airline industry. Most studies measured service quality using SERVQUAL based on a survey method. This study offers a new perspective by employing a big data analytic approach using SNS data, which reflects the immediate response of customers as well as trends in real time. This study chose eight factors from TripAdvisor's customer review site as determinants of customer satisfaction and compared the differences between low-cost and full-service airlines. The factors analyzed were seat comfort, customer service, cleanliness, food and beverage, legroom, entertainment, value for money, and check-in and boarding. Additionally, ratings from domestic and foreign customers were compared. The findings show that customer service and value for money are significant factors in satisfaction with low-cost airlines while all variables except legroom and entertainment are significant for full-service airlines. The results show that SNS-based data and analysis of big data are important for improving decision-making effectiveness and increasing customer satisfaction in the airline industry.

This study was aimed at developing 1) iso-perception maps for various groups of drivers in terms of age, gender, and anthropometry and 2) the experiment framework required for obtaining subjective and objective measures. A total of 9 maps, which describe drivers' perceptions regarding their static behaviors inside a typical mid-size sedan, can be used to improve the utilization of the limited driver workspace, and to select better design alternatives for occupant packaging. An adjustable seating buck, $a^{***}$-camera motion capture system (Vicon), and $a^{**}$-channel EMG system were used for the experiment. Each iso-perception map was developed while H-PT, steering wheel center, or TGS knob center was moved to each of pre-defined positions relative to driver-selected positions. Adjustable ranges or positions of the seat, steering wheel, and TGS lever described in iso-perception maps can be used to determine better package layout alternatives.

This paper presents a mathematical model for a double-fleet operation in Korean high speed rail (HSR). KORAIL has a plan to launch new HSR units in 2010, which are composed of 10 railcars. The double-fleet operation assigns a single-unit or two-unit fleet to a segment, accommodating demand fluctuation. The proposed model assumes stochastic demand and uses chance-constrained constraints to assure a preset service level. It can be used in the tactical planning stage of the rail management as it includes several real-world conditions, such as the capacities of the infra-structures and operational procedures. In the solution approach, the expected revenue in the objective function is linearized by using expected marginal revenue, and the chance-constrained constraints are linearized by assuming that demands are normally distributed. Subsequently, the model can be solved by a mixed-integer linear programming solver fur small size problems. The test results of the model applied to Friday morning train schedules for one month sample data from KTX operation in 2004 shows that the proposed model could be utilized to determine the effectiveness of double-fleet operation, which could significantly increase the expected profit and seat utilization rates when properly maneuvered.

The trend of studying is changing, and it is not a place to study but also a new cultural environment. The study cafe, which is relatively free and comfortable compared to a stuffy library or reading room, is suitable for an unmanned system that can generate greater profits by reducing labor costs. However, the system that can manage this systematically is still insufficient and needs to be supplemented. In this paper, we developed an Android application that integrates the unattended study cafe and provides convenience to users through additional functions. The user and the manager are separated so that the user can use the desired study cafe in the corresponding region through reservation and inquiry of the seat. The manager manages seats and members and allows the outside of the cafeteria to check the current situation. In addition, community and noise measurements and member time visualization capabilities have been added to enhance application utilization.
