Advanced Traveler Inoformation Systems*ATIS) , as a subsystem of ITS influence the travel choices of dreivers by providing them with historical, real-time and predictive information to supprot travel decisions and consequently improves the speed and quality of travel. For thesuccessul accomplishment of ATIS, the time-dependent variations of traffic in a road network and travel times of vehicles during their journey must be predicted . The purpose of this study is to evaluate the past developments in the dynamic route choice models and to apply the instantaneous dynamic user optimal route choice model. recently formulated with flow propagation constraints by Ran, Boyce and LeBlanc, to the real transportation network of Seocho-Ku in Seoul. As input data for this application, the time-dependent travel rates are estimated and the link travel time function is derived. The modelis validated from three view points : the efficiency of model itself the ability to predict traffic volume and travel time on links, and the optimal traffic control.

The first-best pricing rule which achieves economic efficiency is to equate price with marginal cost. Since public transport demand is derived from some other demand, the user cost as well as the producer cost are considered in its pricing. The optimal price is derived from a derivative of the total social cost with respect to demand. In case of the bus, if there is enough capacity for demand increase, the optimal price is determined by the marginal producer cost resulting from bus sped decrease and by the marginal user cost resulting from journey time increase. Both are caused by boarding and fare collecting time of an additional passenger. Because of the budget constraints, the marginal cost pricing cannot be applied in practice. Then price discrimination as the second-best pricing is introduced. The Ramsey pricing, to charge different prices for different demand elasticities, and nonuniform prices such as travelcards can be applied. However, there is practical difficulty in implementing these prices because of great informational requirements, the costs of administration and the ease to users.

Currently, the motion picture and game are leading the entertainment industry based on "One Source Multi Use" system, Games and films hold widely the subjects and stories in common, but we seldom find the successful cases, In each case of cinematizing game or making game of a film, the question is "Story Value" the essential of storytelling. This study cross analyzed Story Value of both cases of games based on the films and cinematized games, and propose an compatible Story Value between games and films.

The pedestrian space of the street is one of the most important public places in the city. Sidewalks are the paths that everyone travels, and the spaces in which everyone comes together. By Whatever means they travel, everyone is ultimately a pedestrian during their journey through the residential area. Every year, more than six thousand Koreans are victimized by traffic accidents, and a half of them are pedestrians. This study aims at improving the pedestrian environment in residential area, and thus making road a walkable, pedestrian-friendly space. The study reviews the problems in the pedestrian environment of residential area and proposes improvement strategies.

Tourism is a word meaning enjoyable based on tourism order. No matter how free is the journey guaranteed, there is a limit to the orders travellers follow. In other words, constitutionalism suitable for a region or country can be found in any tourist resort at home and abroad. Foreign or local tourism travelling in Korea have tourism-related rules to keep, and people working for tourism and organization of it have also rules. Therefore, a study for the rule of law is needed in aspect of how to improve tourism. Unfortunately, none of those rules of law to be followed by tourist and people working for tourism have not been researched. For instance, any principle of law has not been studied to help improve people-to-people diplomacy and national economy those of which are emphasized by tourism basic law. Finally, a research is needed for law reforms that guide tourism in future.

The Breakthrough Starshot initiative aims to launch gram-scale spacecraft to a speed of v~0.2c, capable of reaching Alpha Centauri and seeing the Earth-like exoplanet, Proxima b, from close distance, in about 20 years. However, a critical challenge for the initiative is the effects of interstellar matter and magnetic field to the relativistic spacecraft during the journey. In this talk, I will first present our evaluation for the damage to the spacecraft by interstellar gas and dust based on a detailed analysis of the interaction of a relativistic spacecraft with the ISM. Second, I will discuss the deflection and oscillation of spacecraft by interstellar magnetic fields. Third, I will discuss the gas drag fore at high energy regime and quantify its effect on the slowing down of the relativistic lightsails. Finally, we will discuss practical strategies to mitigate the damage by interstellar dust and to maintain the spacecraft aiming at the intended target.

As humanity embarks on its learning journey in the 21st century, education needs to take on new dimensions. This discourse focuses on the essentials of what educators could do to promote creative development in young gifted and talented students.Current practices in Singapore's Gifted Education Programme are shared. Future possibilities of educating the young gifted studentson their creative attributes like Piirto's 7 Is, brain functions, energy levels or intensities, volition, virtues and other personal and interpersonal skills will be explained. Gifted students are the captains of their own ships, the pilot of their own planes. Teaching them about their creative potential is the first step in awakening their consciousness from within. It is up to them to decide to become more creative with support from parents and teachers thereafter.

Human papillomavirus (HPV) is a prevalent sexually transmitted infection with serious medical, sexual, and relationship consequences. HPV vaccine protection is available globally but unfortunately vaccine uptake is inconsistent everywhere. From this study, it was observed that the awareness of cervical cancer, HPV virus and HPV vaccination in Malaysia is high, at 83.1%, 73.9% and 73.3% of respondents, respectively. However, a considerably low percentage had undergone HPV vaccination (8.6%) compared to those who had experienced a Pap smear (32.9%). Awareness between cervical cancer and HPV virus and vaccination was low. Health care providers and the governing bodies have to play a vital role in disseminating holistic information on the vaccine and the importance of getting vaccinated to the public more vigorously in Malaysia.

This paper briefly elucidates the journey of Library and Information Science (LIS) journals published from India since 1912-2016. The study explores that 196 LIS journals have been produced in India during the past 11 decades covering the period from 1912-2016. The states namely New Delhi, Tamil Nadu, Maharashtra and West Bengal have contributed significantly andNew Delhi emerges as the most productive city among the others regarding the production of LIS journals. The study reveals that out of total 196 journals, 15 have been indexed in the University Grants Commission Academic Performance Indicators List and 41 have found their place in national and international indexing and abstracting sources.

Microsurgery training in Singapore began in 1980 with the opening of the Experimental Surgical Unit. Since then, the unit has continued to grow and have held microsurgical training courses biannually. The road to becoming a full-fledged reconstructive surgeon requires the mastering of both microvascular as well as flap raising techniques and requires time, patience and good training facilities. In Singapore, over the past 2 decades, we have had the opportunity to develop good training facilities and to refine our surgical education programmes in reconstructive microsurgery. In this article, we share our experience with training in reconstructive microsurgery.
