PURPOSES : The objective of this study is to investigate the current state of the practice, examining the steps in the process recommended by various agencies and the Asphalt Recycling and Reclaiming Association (ARRA)-namely mix design, structural design, structural capacity evaluation, and material characterization-in order to better understand the implications of hot in-place recycling (HIR). METHODS : In addition, the current practice of state departments of transportation (DOTs) is here reviewed with the purpose of learning from successful past experiences so as to forestall any difficulties that may emerge under similar circumstances. Also, HIR benefits, including reduced costs, improved construction processes, and environmental friendliness are presented, as well as advantages and disadvantages of HIR application. RESULTS : Most of the United States highway system is now deteriorating so that rehabilitation or reconstruction techniques are required for the most distressed roads, taking into account ways to increase the effectiveness of existing budgets. Several options are available in rehabilitating distressed roads, and the choice among these depends on many factors, including pavement distress condition, funding, and design life. Among these techniques, Hot In-Place Recycling (HIR) has emerged as a cost-effective treatment for deteriorated pavements, and has been proven an effective long-term strategy for pavement rehabilitation.

Objectives: The purpose of this study was to examine the correlation between oral malodor and related factors in visitors to preventive dentistry practice lab. Methods: The subjects were selected from 71 visitors to preventive dentistry practice lab in a department of dental hygiene. The subjects were from twenty to twenty nine years old and had no systemic diseases or symptoms. The questionnaire consisted of general characteristics, oral malodor concentration, oral health status, oral health behavior, and self-rated oral malodor. Results: The mean concentration of the oral cavity gas was 50.80. The score of 50.80 was a weak smell by the selected judgement criteria. The oral malodor prevalence rate accounted for 39.1 percent and a weak smell was detected in 40 points. Those having higher oral malodor concentration tended to have lower self-rated oral health status(p<0.05). Conclusions: The results can not be generalized to determine the cause of oral malodor, but self-rated oral health status can be linked to systemic disease control. More investigation should be taken in order to analyzed the correlation between oral malodor and systemic diseases.

Objective: Clinical practice guidelines (CPGs) are systematically developed statements aimed at helping optimal care of the patient in a given clinical circumstance. Because of the increasing evidence that active implementation of CPGs improve health outcomes, there is a growing awareness of the importance of guideline development and dissemination. The objective of this study was to investigate the status of CPG development and availability of the CPGs in Korea. Method: We searched in the Web sites of 180 organizations to identify CPGs which were developed and/or published in Korea until 1 July 2014. The data of titles, published year, publisher, distributer, and accessibility at the internet web of all CPGs were collected and analyzed. Results: A total of 172 CPGs were developed and 80% had been released since 2009. Most (51.2%) were developed for management of 4 diseases: 28 for digestive system disease; 27 for infectious disease; 18 for endocrine and metabolic diseases; and 15 for neoplasms. Of the 172 CPGs, 150 CPGs were publicly available. Among the 150 CPGs, 78.7% (118/150) were developed by only one organization. Conclusion: To ensure the production of high-quality CPGs, it is necessary to collaborate with other relevant professional societies in guideline development process. In addition, stronger efforts on wider dissemination of CPGs must be employed at the country levels to promote implementation of CPGs in clinical settings.
