  • Recently, a number of OBU(On Board Unit) have being spreaded since ETCS(Electronic Toll Collection System)using DSRC(Dedicated Short Range Communication) was installed in the tollgate of the whole country. Many R&D and commercialization related to ITS service using DSRC and OBU mentioned above are ongoing such as traffic information collection and provision and a signal control, and public traffic information and management and so on. Especially, there are many researches conducted(conducting) on traffic information collection and provision using communication between OBU and RSE. However, Standards for both DSRC application and traffic collection and provision are not established clearly yet. So we would like to suggest a method of traffic information collection and provision without changing of standard related to DSRC. This method is to put the traffic messages into the existing Action primitive for ETC, which is described on "Technical criterion IV of basic traffic information exchange" which was notified by Ministry of Land, Transport and Maritime Affairs. Proposed standard application method is applied both to RSE and OBE. It is the same system which ETCS used in highway, currently. We confirmed the efficiency and performance of the system through conducting a variety of driving test using 4 vehicles in real road condition. Result of the real road test shows the effectiveness and validity of this method with about 97% communication success rate and based on studying the cases of 3% communication failure, we can analyse the expected problems in traffic information collection and provision using this method.

  • In response to the government's recent attempts to introduce competition and efficiency criteria in the rural railway service provision, this study is to empirically estimate public service values on continuous operation of two rural railways-Young Dong Line (YDL) and Donghae Nambu Line (DNL)-that will be realized beyond the passengers' use values. Based on a contingent valuation survey conducted on 600 passengers and local residents, YDL respondents were willing to pay significantly higher amount compared to those of DNL respondents. Especially tourists traveling on YDL were willing to pay the highest amount, and local residents of DNL were willing to pay relatively high amount. The results will provide useful information in makings decisions on the selection of PSO railways, the amount of PSO compensation and which railways to close, so on.

For research, we compare to IBM of consumer awareness surveys an AI shopping information service for retailing channel and target goods group. Finally, we present to service scenario for distribution service using AI. Research design, data, and methodology - First, to identify possible the success of the information service shopping using AI, AI technology for the consumer is very important for the acceptance of judgement. Therefore, we explored the possibility of AI information service for business as a shopping. The experimental data were used to interpret the meaning of the relevant literature and the IBM Institute of Business Value (IBV) Report 2015. This research is based on the use of a technical acceptance model (TAM) to determine whether the consumer would adopt the 'AI shopping information service' technology. Step 1 of the process assumes that the consumer adopts AI technology. In step 2, consumers find their preference channels and goods targeted at them as per their preferences. Finally Step 3, we present scenario for 'AI shopping information service' based on the results of Step 1 and 2. Results - Consumers have expressed their high interests in the new shopping information services, especially the on/off line distribution channels can use shopping information to increase the efficiency in provision of goods. Digital channel (such as SNS, online shopping etc.) is especially high value goods such as cars, furniture, and home appliances by displaying it to an appropriate product group. Conclusions - The study reveals the potential for the use of new business models such as 'AI shopping information service' by the distribution industry. We present seven scenario related AI application refer from IBM suggestion, and the findings would enable the distribution industry to approach target consumers with their products, especially high value goods. 'Shopping advisor' is considered to the most effective.

  • Cloud computing promises high performance and cost-efficiency. However, most cloud infrastructures operate at a low utilization, which greatly adheres cost effectiveness. Previous works focus on seeking efficient virtual machine (VM) consolidation strategies to increase the utilization of virtual resources in production environment, but overlook the under-utilization of backup virtual resources. We propose a heuristic time sharing policy of backup VMs derived from the restless multi-armed bandit problem. The proposed policy achieves increasing backup virtual resources utilization and providing high availability. Both the results in simulation and prototype system experiments show that the traditional 1:1 backup provision can be extended to 1:M (M≫1) between the backup VMs and the service VMs, and the utilization of backup VMs can be enhanced significantly.

  • Background : One-quarter of Koreans are either students or school employeeS. Therefore, school health programs for them have high levels of cost-benefit. School health programs, though, are focused on services such as vaccination and physical examination according to administrational regulations without systemic planning. Futhermore, college health programs run autonomously, not under the supervision of the Ministry of Education. It is my intention to analyse the current status of college school health service centers and use the basic data so generated to model how they might operate at an optimal level of efficiency. Methods : I intended to investigate all 29 colleges in Seoul except some specialized colleges such as theological schools in the two-month period of August and September, 1999. I used the telephone interview method to ask questions relating to personal composition, medical equipment in use, annual expenditure and the provision of school health services. School health services were composed of three items; health servies, health education and a healthy school environment. Results : 27 college health service centers were surveyed. The median number of medical personal in each center was 2, the range was 1-31. 7 centers(25.9%) have only nurses with no doctors. Annual expenditures of 11 centers(50.1%) was less than 10 million won, 19 center(70.4%) were maintained by support from their college. Thirteen centers(48.1%) provided doctor's examinations, 6 centers(22.2%) provided dental care services, laboratory services were provided by seven centers(25.9%). Some 81.5% of the centers had vaccination programs and 44.5% had health education programs. There was no school environment program except insecticide provisions. College health service centers with school doctors differed from centers without school doctors in terms of medical equipment range, annual expenditures and annual case loads. Conclusion : The structure and function of college health service centers in Seoul are diverse. However, no center has a well-organized school health plan.
