Properties of statistical process control procedures may not be derived analytically in many cases; however, the application of a Markov chain can solve such problems. This article shows how to derive the properties of the process control procedures using the generated Markov chains when the control statistic satisfies the Markov property. Markov chain approaches that appear in the literature (such as the statistical design and economic design of the control chart as well as the variable sampling rate design) are reviewed along with the introduction of research results for application to a new control procedure and reset chart. The joint application of a Markov chain approach and analytical solutions (when available) can guarantee the correct derivation of the properties. A Markov chain approach is recommended over simulation studies due to its precise derivation of properties and short calculation times.

Objectives: This study aimed to compare the postoperative pain and clinical performance after applying three different intracanal medicaments and root canal sealers. Materials and Methods: Sixty-five patients requiring root canal treatment due to symptomatic apical periodontitis were included in this study. After a glide path preparation by using PathFile, each canal was shaped with ProTaper Next file system. After the canal cleaning and shaping procedure, the canal was dried and each intracanal medicaments were adjusted (Calcipex II, TRC-paste, Metapaste). At the next visit, the patients were requested to answer the absence of the pain after the procedure. Once the patients showed no symptom, the canal was obturated with each corresponded root canal sealers (AH plus, Radic-sealer, ADseal). The patients were recalled after 1 week, 1, 3, and 6 months to check the postoperative pain or unexpected clinical signs. One-way ANOVA and Duncan's post hoc comparison, and Chi-square test were used for statistical analysis to evaluate any differences among tested materials. Results: The average number of visits for intracanal medication was 2.69, 2.65, and 2.61 for Calcipex II, TRC-paste, and Metapaste. There were no statistically differences in post-obturation pain among three groups obturated with different root canal sealers (P > 0.05). Conclusions: Under the limitations of this study, three tested intracanal medicaments and epoxy resin root canal sealers showed clinically acceptable similar results.

Objectives: The aim of this study was to estimate drug prescription indicators in outpatient services provided at Iran Social Security Organization (SSO) healthcare facilities. Methods: Data on all prescribed drugs for outpatient visits from 2017 to 2018 were extracted from the SSO database. The data were categorized into 4 main subgroups: patient characteristics, provider characteristics, service characteristics, and type of healthcare facility. Logistic regression models were used to detect risk factors for inappropriate drug prescriptions. SPSS and IBM Modeler software were utilized for data analysis. Results: In 2017, approximately 150 981 752 drug items were issued to outpatients referred to SSO healthcare facilities in Iran. The average number of drug items per outpatient prescription was estimated at 3.33. The proportion of prescriptions that included an injection was 17.5%, and the rate of prescriptions that included an antibiotic was 37.5%. Factors such as patient sex and age, provider specialty, type of facility, and time of outpatient visit were associated with the risk of inappropriate prescriptions. Conclusions: In this study, all drug prescription criteria exceeded the recommended limits set by the World Health Organization. To improve the current prescription patterns throughout the country, it would be beneficial to provide providers with monthly and annual reports and to consider implementing some prescription policies for physicians.

To determine the incidence rate of school accidents and its associated factors, a cohort observation was carried out in a boys' high school of a total of 2,324 students for an academic year from March 1986 to February 1987. Data for accidents were collected by the author (school nurse) as students came to the school health station for treatment of accidental injury. Data for school activities were obtained from the diary of academic affairs. A total of 603 students made 1,126 visits to the station for accidental injury during the study period that gave an average 1.9 accidents per student. The average number of visits for accidental injury per day was 5.1 and the incidence rate of accidental injury was 2.2 per 1,000 student days. Each class had about 30 accidents on the average in a year. However there were two classes that had exceptionally high incidence rate of accidents; 54 accidents in one class where 10 athletes were assigned and 58 accidents in the other class where the teacher in charge was On vacation for two months. The highest incidence rate of accident was observed in June (3.4 per 1,000 student days) and the lowest rates were in December and February (1.5 and 0.7 per 1,000 student days, respectively) and there were no appreciable difference by day of week. Accidents were caused by mischief or carelessness of students in 62.2% and by the inappropriate tools and facilities of school in 18.6% . The accidents caused by tools and facilities were mainly due to the antiquated chairs and tables. Referral rate to hospital for severe injury was three times higher in cloudy days and five times higher in rainy days than in clear days. There was almost no accident during the examination period but increased after the examination. Based on these findings, following measures are recommended to prevent school accident: disperse the athletes throughout the classes: should the teacher in charge leave the class for a long period, replace with another teacher who is familiar with the class to keep order; replace or repair the inappropriate tools and facilities; and warn the students for the risk of accident or broadcast music or let the students have light physical exercise to relieve the tension in cloudy or rainy day and after examination.

In this study, we conducted a statistical analysis to see how visitors were satisfied through experiences at the Goseong Dinosaur Museum, which is a representative natural history museum in the Republic of Korea. As a result, during the last 10 years (2005-2014) the total number of visitors to the Goseong Dinosaur Museum was more than 3,410,000 persons. The maximum- and minimum number of visitors per year was more than 440,000 and 300,000 persons, respectively. The annual average number was more than ca. 340,000 persons. Among the visitors, the number of individual visitors was more than 2,800,000 persons (82.0%) and the number of group visitors was about 610,000 persons (18.0%). As a result of the monthly visitor analysis, the maximum number of visitors was about 530,000 persons in August while the minimum number of visitors was about 140,000 persons in February. The visiting patterns of the individual and group visitors were different. There were the largest number of the individual visitors in August and the smallest number of them in December, whereas the largest number of the group visitors in October and the smallest number of them in February. The visitor's residence was generally proportional to the geographical accessibility and the number of people in their residence. The results showed that the degree of visitor's satisfaction using Likert scale was relatively high with the score of 4.1. However, the visitors recommended that some facilities should be improved. Regarding the number of visits and the intention of revisit, 102 persons (53.1%) of 192 made a visit to the museum more than two times, and 178 persons (89.9%) of 198 visitors would like to visit the museum again. It is recommended that the results of this study be used in developing a long term-plan or for the Goseong Dinosaur Museum.
