Objectives: This retrospective study aims to evaluate the prevalence of maxillofacial trauma in a developing country, along with its pattern, etiology and management. Data for the present study were collected from the Department of Dentistry, ESIC Medical College and Post Graduate Institute of Medical Sciences and Research, Chennai in India. Materials and Methods: The medical records of patients treated for maxillofacial injuries between May 2014 and November 2015 were retrospectively retrieved and analyzed for prevalence, pattern, etiology, and management of maxillofacial trauma. SPSS software version 16.0 was used for the data analysis. Results: Maxillofacial fractures accounts for 93.3% of total injuries. The mean and standard deviation for the age of the patients were $35.0{\pm}11.8$ years and with a minimum age of 5 years and maximum age of 75 years. Adults from 20 to 40 years age groups were more commonly involved, with a male to female ratio of 3:1. There was a statistically significantly higher proportion of males more commonly involved in accident and injuries (P <0.001). Conclusion: The most common etiology of maxillofacial injury was road traffic accidents (RTA) followed by falls and assaults, the sports injuries seem to be very less. In RTA, motorized two-wheelers (MTW) were the most common cause of incidents. The majority of victims of RTA were young adult males between the ages of 20 to 40 years. The malar bone and maxilla were the most common sites of fracture, followed by the mandible. The right side of the zygomatic complex was the predominant side of MTW injury. The majority of the zygomatic complex fractures were treated by conservative management. Open reduction and internal fixation were performed for indicated fracture patients.

Background: Medical practitioners' attitudes have a significant impact on quality of care for cancer pain patients. This study was conducted to determine if being given a lecture concerning cancer pain and its management could improve the attitudes of medical students. Materials and Methods: A comparative study was conducted in 126 fifth-year medical students. Each student completed a pretest consisting of 3 questions about attitudes toward the optimal use of analgesics and 5 questions about attitudes toward prescribing opioids. Then they were given a 1.5-hour lecture, immediately following which they completed a post-test with the same questions. Results: Analysis with either comparison between groups or by matching, the post-test showed significantly more positive attitudes (p<0.05) of the medical students in all 3 questions about optimal use of analgesics and 4 out of 5 questions about prescription of opioids. The post-test results showed significantly more negative attitudes concerning the most appropriate stage for patients with severe pain to receive maximal doses of analgesics. Conclusions: Conservative attitudes, especially concerns about addiction, have been associated with a reluctance in many physicians to prescribe opioids. This study found that cancer pain education can help to improve medical student attitudes. However, fear of addiction and tolerance was still evident so emphasis of this particular issue during a lecture is essential. Providing appropriate information by means of a lecture can improve the attitudes of medical students regarding cancer pain management. However, more information should be given to lessen fear of addiction and tolerance.

The goal of this study was to evaluate the effects of cryoprotectants [dimethyl sulfoxide (DMSO), methanol, polyethylene glycol, and propylene glycol], cryoprotectant concentrations (10% and 20%), equilibration time (3, 10, and 30 min), cooling rate ($3^{\circ}$, $5^{\circ}$, $7^{\circ}$, and $10^{\circ}/min$), and straw size (0.25 and 0.5 mL) for sperm cryopreservation of tetraploid Pacific oysters. There was a significant difference among the four cryoprotectants, with 10% DMSO yielding the highest post-thaw survival and activity index of sperm. A significant relationship was observed between the cryoprotectant and its concentration. The sperm with equilibration times of 30 min yielded higher post-thaw survival and activity indices than those with 3 and 10 min equilibration times. The sperm cooled at a rate of $5^{\circ}/min$ yielded the highest post-thaw survival and activity index, and the results were significantly different from those observed for cooling at $7^{\circ}$ and $10^{\circ}/min$. Post-thaw survival and activity indices of sperm using a 0.25-mL straw were significantly higher than those using a 0.5-mL straw.

This study was conducted to investigate the job-performance of manual wheelchair post-management and to find out the relationship between job-performance and vocational ability of people with developmental disabilities. In this study, situational evaluation and vocational evaluation were conducted for 9 subjects participated in the vocational training program about manual wheelchair post-management. The data was analyzed by non-parametric statistical processing. As a result, the job-performance was an average of 80.87%. The job-performance had a positive correlations with visual closure, kinesthetic integration, and basic concepts(p<.05). The relationship between job-performance and vocational abilities can be used as basic data for vocational training program and job assignment. It is expected to be useful of spreading the post-management job for assistive technology devices in the local community activated through the convergence of assistive technology and vocational rehabilitation.

Purpose: This study was aimed to develop and evaluate of a Problem-based Learning (PBL) in the course of Nursing Management and Ethics. Method: The design of the study was both methodological and one group only pre-post design. The sample included 61 senior students who are currently enrolled in Nursing management and Ethics course in college of nursing. Data regarding PBL evaluation were collected on the critical thinking and clinical reasoning using structured questionnaires during March to June, 2005. Data were analyzed using descriptives and paired t-test. Results: A total of three PBL packages was developed by the two faculty members and two teaching assistants who are majoring in nursing management. PBL packages that had been developed was applied to 61 senior students for three months. Critical thinking and clinical reasoning were measured twice pre and post the application of PBL packages. There were statistically significant differences in the critical thinking and clinical reasoning between the pre and post PBL application. Conclusion: PBL was considered to be effective in understanding the learning concepts in the Nursing Management and Ethics. Further research on the facilitative strategies and development model considering the characteristics of Nursing Management and Ethics course is needed.

Background : Hypercholesterolemia is a major independent risk factor of coronary heart disease. Practice guidelines for management of hypercholesterolemia had been made in several developed countries. This study was undertaken to assess the effect of practice guideline reminders and flow-sheets to improve the quality of management of hypercholesterolemia. Methods: Practice guideline reminders and flow-sheets based on National Cholesterol Education Program Adult Treatment Panel II guidelines, were placed on the office desks of outpatient department of family medicine at the Asan Medical Center. Before this intervention, we educated the doctors to use these reminders and flow-sheets. The charts of all patients who had cholesterol levels greater than or equal to 240 mg/dl during 4 months before and after introduction of reminders and flow-sheets, were reviewed retrospectively. We compared the performances of physicians about management of hypercholesterolemia between pre-intervention period and post-intervention period. Results: The detection rate of hypercholesterolemia in post-intervention period was increased to 83.2% compared by 71.5% in pre-intervention period. Risk factor analysis for coronary heart disease increased significantly from 16.9% to 68.7%. Adequacy of management was 19.2% in pre-intervention period and 78.0% in post-intervention period. It showed statistically significant improvement in management of hypercholesterolemia. Conclusion : This study suggested that practice guideline reminders and flow-sheets were the effective methods in improving the quality in management of hypercholesterolemia.

This research addresses examining the service recovery process in Airline service. A service recovery framework is suggested and tested empirically. The framework includes several factors such as service recovery expectations, service recovery achievements, recovery performance, post-recovery satisfaction, and post-recovery behavioral intents. The relationships among these factors are hypothesized and proved empirically. Consequently the results suggest that recovery expectation impacts on recovery performance significantly. Also the higher the recovery performance, the higher post-recovery satisfaction, then it increases customers' purchase intent and words of mouth. Finally, this paper suggests the need for new service recovery strategies.

The purpose of this study is the comparative analysis of Susan citizens' images of Eulsook-do as a coastal tourism destination before and after the construction of a road bridge across the Nakdong estuary in order to analyze local people's changes in leisure patterns. Analysis of the images of a pre-construction Eulsook-do that people aged both 40 and less and 50 and more had on five dimensions showed values higher than zero(0) that suggests neutral image, while their images of a post-construction Eulsook-do showed the shrinking size of pentagon on all five dimensions: ET(Entertainment), CA(Culture & Art), EE(Environment & Ecology), RC(Recreation) and LP(Leports) dimensions. Its pre- and post- construction image analysis conducted 20 years after it came to be built finds that the road bridge construction has led to the ecological, environmental disruption of the coast and the lower Nakdong river, having negative influence on the images of Eulsook-so.

Delay has influenced customer satisfaction while using a telephone. It has been ranked second after transmission impairments in annoyance to customers. Therefore, it is important to analyze its behavior not only to increase the quality of service for the customers, but to provide its information to network planners and administrators and to designers of equipment and systems. In this paper, we consider a log-normal model as a candidate for describing the statistical behavior of the post dialling delay, i.e., the time to connect a call to the telephone network after dialling. Based on the real data, the log-normalness of the post dialling delays are convinced for the long distance calls, but not supported for the local calls. Uses of graphical plotting paper and statistical test of fit art discussed.
