  • PURPOSES: In this study, as part of an effort to develop HUD for public transit, it is proposed that the decision of order priority of contents which will be disposed to bus drivers through HUD for public transit using AHP(Analytic Hierarchy Process) technique. METHODS: In AHP analysis method brainstorming, factor analysis, hierarchical structuring, and weighting analysis were performed by applying a classical analysis method. RESULTS: By the result of analysis it is shown that unlike car drivers, bus drivers prefer information related to bus intervals, bus stop, and door open and close to information related to vehicle running. Also, bus stop information and bus interval information were ranked as first and second place in order priority of HUD contents for public transit by experts. CONCLUSIONS: This method of selecting order priority of HUD contents for public transit can provide a basic foundation for selecting order priority of traffic information contents as well as other HUD contents.

  • l. Objectives This study aims to know the coefficient of five Sasang constitution diagnosis factors' concordance in and among Oriental Medical Clinics, which are important to diagnose Sasang constitution, 2. Methods We collected 701 subjects in Oriental Medical Clinics, who were diagnosed by experts, and they marked the priority order of Sasang constitutional factors in paper. 3. Results 1) The concordance of priority order about Sasang constitutional factors was significantly associated within Oriental Medical Clinics. 2) The concordance of priority order of Sasang constitutional factors was not significantly associated among 12 Oriental Medical Clinics, so we find out that each medical clinics has a different point of view of deciding the rank of diagnosis factors. 3) We show that the factor of Sasang constitutional drug response was the most important one to confirm Sasang constitution and factors have a different order according to clinic type and qualification of experts 4. Conclusions Sasang constitution expect has their own view in diagnosis priority order and that was different among them.

  • In nuclear power plant, it has been the important object to reduce the occupational radiation exposure (ORE). Recently, the optimization concept of management science has been studied to reduce the ORE in nuclear power plant. In optimization of the worker allocation, the collective dose, working time, individual dose, an total number of worker must be considered and their priority orders must be thought because the main constraint is necessary for determining the constraints variable of the radiological worker allocation problem. The ultimate object of this study s to look into the change of the optimal allocation of the radiological worker as priority order changes. In this study, the priority order is the characteristic of goal programming that is a kind of multi-objective linear programming. From a result of study using goal programming, the total number of worker and collective dose of worker have changed as the priority order has changed and the collective dose limit have played an important role in reducing the ORE.

  • The assumption of reinvestment rate leads to the results conflicting with the priority order of investments determined by net present worth. It has been revealed through various studies that the priority order of projects determined by the criteria based on internal rate of return is different from that determined by present worth. This study is to find out how to define reinvestment rate of return influencing the decision-making of the priority order through examining the meanings of reinvestment rate of capital and true rate of return, and to present some examples with a simple mathematical model.

  • This paper investigates a priority scheme for IEEE 802.11 Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) protocol in order to provide short access times for priority frames (e.g. time-deadline traffic) even when the overall traffic on the wireless channel is heavy. Under the compatibility constraint for the IEEE 802.11 wireless LANs, two priority systems are simulated: no priority (current IEEE 802.11 standard) for time-deadline traffics and dynamic time-deadline priority. We evaluate algorithms to improve the time-deadline traffic performance using discrete event simulation (DES)

  • This study was conducted to analyze the type and priority order of forest functions that is suitable in assessing a private forest. A questionnaire survey of experts group and forest officers from the city and county office was conducted and the appropriateness of forest functions type and priority order of function were assessed. Based on the survey conducted, they mostly agreed that it is necessary to change the name of forest functions and integrate the forest functions. Four classifications of forest functions were presented: resources rotation, water yield, living environment, and forest conservation. As the variety of organizations and geographical areas determine which forest functions are the priority, it is necessary to determine which function will become the priority order according to geographical areas, instead of simply dividing the forest functions into national and publicly owned forest when assessing the forest functions of private forests across the nation.

  • This study is to develop a Priority Decision System for Redevelopment (PDSR) which is able to decide the priority for redevelopment of agricultural reservoirs. The major scopes of this research are to make the related GIS data like hydrologic unit map and other thematic maps to determine the suggested priority index (PI), and to develop the PDSR handling the GIS data and calculating weighing factors for the PI. In order to make the weighing factor decision module, the AHP technique was adopted. The result of the weighing factor calculation was showed PC (Possibility Criteria) and RC (Restriction Criteria) were 76% and 24% respectively. Which means that most of the specialist selected PC category prior to RC because of whom to mostly of major technique. So, in order to make more objective result, the selection of specialists is important like environmental activists or local residents and so on. The product from this research can provide more scientific support to decide the priority decision.
