  • At present the identification of vessels is still depending on the OOW (Officer Of Wateh) in VTS (Vessel Traffic Service), which is completed by radar, and also by the combination of VHF radio and VHF direction finder. However, with the development of port transportation and economic, this conventional way of identification can't satisfy more and more request for the information that the VTS needs from the vessels. In such a case, the AIS(Automatic Identification System) precept which is based on STDMA (Self-organized Time Division Multiple Access) technique is put forward by IMO (International Maritime Organization). AIS can automatically provide the information, including own ship's identification, type, position, course, speed, and other information to the appropriately equipped coast station and other ships. At the same time it can also automatically monitor and track the nearby ships similarly fitted with AIS. On the basis of describing the whole comprising and the format of transmission information of AIS, this paper mainly studies the key communication techniques in AIS, such as STDMA protocol, net synchronization and GMSK(Gaussian Minimum Shift Keying)technique, and so on. At last this paper briefly introduces the recommendation decided by IMO on forcing the sea-going ships to fixed with AIS equipments, and it continuos with the unexploited potential of AIS if it applies in VTS.

  • Objectives : This study investigates the association between weather conditions and the rate of no-shows at an academic medical center. Methods : Electronic data regarding medical appointments atover the course ofone academic year (2016.03~2017.02) were used for analysis. Characteristics of weather conditions and the daily number of no-shows were compared by Chi-square test. A logistic regression was run to determine if certain aspects of weather affected the rate of no-shows. Results : The results reveal an overall no-show rate of 6.8% that appears to vary in accordance with specific weather conditions. Lower average temperatures, in particular, corresponded with a higher rate of no-show patients. This may indicate that o-show rates in autumn and winter can be expected to exceed those during spring. Conclusions : This study investigates the association between no-show patients and weather conditions, and offers suggestions for augmenting this loss. One recommendation is to begin conducting investigations nationwide in order to provide more useful information.

  • Outcome-based education (OBE) is a tried-and-true teaching technique based on a set of predetermined goals. Program Educational Objectives (PEOs), Program Outcomes (POs), and Course Outcomes (COs) are the components of OBE. At the end of each year, the Program Outcomes are evaluated, and faculty members can submit many recommended measures which dependent on the relationship between the program outcomes and its courses outcomes to improve the quality of program and hence the overall educational program. When a vast number of courses are considered, bad actions may be proposed, resulting in unwanted and incorrect decisions. In this paper, a recommender system, using collaborative filtering and association rules algorithms, is proposed for predicting the best relationship between the program outcomes and its courses in order to improve the attributes of the graduates. First, a parallel algorithm is used for Collaborative Filtering on Data Model, which is designed to increase the efficiency of processing big data. Then, a parallel similar learning outcomes discovery method based on matrix correlation is proposed by mining association rules. As a case study, the proposed recommender system is applied to the Computer Information Systems program, College of Computer Sciences and Information Technology, Al-Baha University, Saudi Arabia for helping Program Quality Administration improving the quality of program outcomes. The obtained results revealed that the suggested recommender system provides more actions for boosting Graduate Attributes quality.

  • Objectives : The purpose of this study was to examine the relationship of oral health behavior factors to oral health promotion behavior in dental hygiene students and nonhealth-related majors, to identify factors affecting their oral health promotion behavior and ultimately to provide information on the oral health promotion of college students and behavioral factors related to that. Methods : The subjects in this study were three-year-course dental hygiene students and two-year-course nonhealth-related majors in G college located in the city of Gwangju. A self-administered survey was conducted for 11 days from September 9 to 19, 2009, and the answer sheets from 473 respondents were analyzed. To look for connections between their major and the characteristics of their oral health promotion behavior, t-test was utilized, and t-test and one-way ANOVA were carried out to find out the relationship oral health promotion behavior by general characteristics. Besides, multiple regression analysis was employed to grasp factors affecting oral health promotion behavior. Results : Among the subfactors of oral health promotion behavior, the dental hygiene students statistically significantly outdid the nonhealth-related majors in thorough post-meal toothbrushing(p<0.01), toothbrushing method(p<0.001), use of fluorine-containing dentifrice(p<0.001) and good nutrition(p<0.05). But the latter statistically significantly outperformed the former in use of fluorine-containing rinse(p<0.001) and limited sugar intake(0<0.05). Regarding variables affecting oral health promotion behavior, the age group, whether to get a dental checkup over the last year and whether to use oral hygiene supplies were identified as the variables to impact on oral health promotion behavior. Specifically, the age group(dental hygiene students) and the get a dental checkup over the last year(nonhealth-related majors) had a greater impact. Conclusions : To promote the oral health of college students, comprehensive oral health education should be provided, which covers the importance of dental checkup, recommendation for the use of oral hygiene supplies, etc. Specifically, oral health education should be offered as one of general education courses in order for nonhealth-related majors to get into sound life habits and improve their oral health promotion behavior. To make it happen, required institutional measures should be taken.
