The second decade
M. Amini
Iranian Journal of Physics Research , 2004,
Abstract: It is ten years since the Iranian Journal of Physics Research has been in publication. For the Occasion of the 10th anniversary of its publication, we have planned several changes and modifications. These includes increasing the annual issues to four and omission of Introduction of Previously-Published Papers in International Journals section. In this article some statistical information of the published articles is given together with the index of the journals referees. As we enter the second decade of our publication, we face several questions. In this article we share these questions with our readers in the hope of finding the best possible solutions, so that we would be able to publish a better journal in future.
The view of faculties and medical students about evaluation of faculty teaching experiences
M. Amini,M. Honardar
Koomesh , 2008,
Abstract: Introduction: Using students' view for teacher evaluation is a common method. This study wasdesigned to investigate the view of faculties and medical students about faculty teaching experiences.Materials and Methods: 100 medical students and 35 faculties from Jahrom University of MedicalSciences were participated in this study. Two separate questionnaires were designed for this purposeand after determining validity and reliability completed by teachers and students.Results: 70.9 percent of faculties reported that they are satisfied with evaluation by students. 48.6percent of them reported that feedback from this evaluation improved their teaching. 48.8 percent ofthem thought that some students behave spitefully. 60 percent reported self assessments as a usefulmethod for evaluation of their own teaching. The majority of medical students (76.6%) reported thatteachers' communication skills are one of the important factors in teacher evaluation. 67.4 percent ofthem reported that they completed the teachers' evaluation forms carefully and 60.9 percent of themasserted that teachers, who take difficult examinations, have lower grades in evaluation forms.Conclusion: In general, most teachers are agreed with teacher evaluation. Since students' opinionabout their teachers is influenced by some factors which have no close relationship with the evaluationsubject and is merely related to other factors, using other evaluation methods such as self evaluationand peer evaluation seems to be necessary. In addition, we should establish a single national andstandard method for teacher evaluation all over the country.

Journal of Research in Medical Sciences , 2001,
Abstract: Introduction. Diabetic control and its acute and chronic complications needed to investigate the characteristics medical and self care in diabetics. This evaluation can detect conflicts in this field and provide the possibility of better planning to arrive the ideal control of diabetes. Methods. This study was a cross sectional survey. Samples were 344 diabetic patients who were living in Isfahan. Data was collected by a questionnaire described diabetics contextual characteristics, position of medical services use, position of diabetic education, self blood glucose monitoring (SMBG), attendance to diet regimen and so on. Questionnaires were cmpeleted through interview. Results. Mean age of patients was 56.5±13.6 years. More than fifty percent (57.7 percent) were female. More than one third (57.6 percent) were illiterate. Patients had 1 to 40 years history of diabetes. More than one forth (27.4 percent) did not seek medical advice and 61.2 percent had referred to physician only when they were encountering with a problem for example lack of insulin or oral hypoglycemic agents. Over eighty percent never had foot examination by their physicians. Only 7.4 percent, had heared about glycosylated hemoglubine. This test had not been accomplished for 95.9 percent of patients. 46.2 percent had not performed self foot examination till study time. More than eighty percent of interviewers had reported their lost blood glucose value above 130 mg/dl. Only ten percent of the study population had performed 5MBG. About fifty percent (45.3 percent), did not educated about diabetes. Only 26.8 percent reported that they always follow their dietary regimen. Discussion. Results of this survey showed irregular calls to physicians, poor blood glucose control, high rate of hospitalization due to acute and chronic diabetes complications, irregular blood glucose monitoring. Diabetes management needs more attention in our city.
Negatively dependent bounded random variable probability inequalities and the strong law of large numbers
M. Amini,A. Bozorgnia
International Journal of Stochastic Analysis , 2000, DOI: 10.1155/s104895330000023x
Abstract: Let X1,…,Xn be negatively dependent uniformly bounded random variables with d.f. F(x). In this paper we obtain bounds for the probabilities P(|∑i=1nXi|≥nt) and P(|ξˆpn−ξp|>ϵ) where ξˆpn is the sample pth quantile and ξp is the pth quantile of F(x). Moreover, we show that ξˆpn is a strongly consistent estimator of ξp under mild restrictions on F(x) in the neighborhood of ξp. We also show that ξˆpn converges completely to ξp.

Paknejad M.,Amini R.
Journal of Dental Medicine , 1999,
Abstract: The root trunk (RT) of molar teeth is important diagnostic parameter that has a key roll in"ndiagnosis and treatment planning."nThe purpose of this study is presenting a normal index of RT in mandibular molar teeth in different"nbuccal (B). distal (D), Lingual (Li) and mesial (M) entrances, and to compare them with each other."nIt is a case series study that 351 extracted molar teeth, after removal of soft tissue and debridement of"ncalculus, evaluated with gauge (with accuracy 0.1 mm)"nAccording to our measurement:"nIn maxilla: M-side: 3.88± 0.15 mm, B-side: 4.7± 1.7. D- side: 4.87± 0.13mm. So with P.value <0.05 M"nand D RT are longer than and M RT is shorter than D RT."nIn mandibule: B- side: 2.73± 0.11mm and L side: 4.03±- 0.13mm. So with P.value < 0.01 Li RT is longer"nthan B RT."nAccording to ochsenbine classification our studying teeth have medium to long RT. We prescribe for"neducating the crater therapy in periodontal surgery the emphasize must be focused on craters with"nmedium and long RT."nThe shortness of RT in B-side of lower molars needed the most attention during osteoctomy in resective"nprocedures. Because RT not depended to underlying factors such as age, social and economic situation,"nand for large amount of sample size in our study, the result could be extended in Tehran.

Pakistan Journal of Biological Sciences , 2009,
Abstract: The aim of this study was to determine the efficacy of oral regimens in patients without active gastric bleeding and those of intravenous regimens in a group with active gastric bleeding. This study was performed as an interventional investigation in Tehran between April 2004 and March 2008. The patients who had active peptic ulcer were included and divided into two groups. One group included 26 subjects with active gastric bleeding and the other included 29 patients without active gastric bleeding. The intravenous treatment included metronidazole, ampicillin, ranitidine and orally administered bismuth for five days. The oral regimen included metronidazole, amoxicillin, ranitidine and bismuth sub-citrate for 14 days. In intravenous group 24 patients (92.3%) and in oral group 24 subjects (82.8%) had no drug adverse events. The successful treatment was seen in 61.5% (16/26) and 55.2% (16/29) in intravenous and oral methods, respectively. Finally, it may be concluded that both five-day intravenous therapeutic regimen in patients with active gastric bleeding and 14-day oral regimen in patients without active gastric bleeding would have good efficacy and low rate of drug adverse events.

Journal of Isfahan Dental School , 2006,
Abstract: Introduction: Systemic disease is often closely linked to the state of the oral cavity. One of thesesystemic diseases is diabetes mellitus. The purpose of this study is to determine the effect of scaling androot planning and mouth rinse on blood sugar level in type 2 diabetic patients. Methods and Materials: 30 uncontrolled type 2 diabetic patients suffering from sever chronicperiodontitis were selected and divided into two groups; each group consisted of 15 patients: Firstgroup (control): received oral hygiene instruction. Second group (case): received scaling and rootplanning plus oral hygiene instruction and chlorhexidine degluconate mouthrinse. In all groups,probing depth (in 6 sites of each tooth), bleeding index (in 4 sites of each tooth), fasting blood sugarand glycated hemoglobin were measured at first and three months after treatment. Then the before andafter treatment results were compared. Results: Mean fasting blood sugar in second group, reduced from 184.2 to 163.87 mg/dl. Glycatedhemoglobin in this group reduced from 8.78% to 7.29% (p<0.05). Bleeding index, plaque index andprobing depth reduction were statistically significant before and after treatment (p<0.05). Conclusion: Phase one periodontal therapy improves periodontal conditions and reduces fastingblood sugar and glycated hemoglobin. Key words: Scaling, Probing depth, Bleeding index, Plaque index, Type 2 diabetes, Glycated hemoglobin,Fasting blood sugar.

Journal of Science and Technology of Agriculture and Natural Resources , 2009,
Abstract: The main purpose of this research is to study the success of rural cooperative companies and evaluate different factors which may influence such a success. For this purpose, sample companies were randomly selected based on multistage and stratification sampling with proportional allocation method,. Finally, 18 rural co-operative companies were studied using questionnaires filled out by 328 ordinary members and 93 members of board of directors and managers of these rural co-operative companies. Inter-organization and intra-organization and structure variables which affected the companies performance and achievement were studied. The findings showed poor performance of these companies. According to the current research, some variables such as membership experience, co-operative structure, co-operative investment, enhancement of member share, education, participation and level of training, awareness (ability) of members have a direct influence on companies' success. The other factors involving function of rural co-operative organization, use of managers’ misuses and abuses in co-operatives have a direct, but negative influence. Share mean value of each member, management experience; knowledge and age of people have also indirect positive effect on success and the size has indirect negative influence on co-operative companies .
Study of Effective Factors on Success of Poultry-Farm Cooperatives in Isfahan Province
A. M. Amini,M. Ramezani
Journal of Science and Technology of Agriculture and Natural Resources , 2006,
Abstract: The general goal of this research was to study the effective factors on the success of the poultry-farm cooperatives in Isfahan province. Based on multi-stage cluster sampling and Chocran formulas, nine cooperatives and 173 members were selected from 15 cooperatives with 1768 members. After completion of questionnaires, the AHP method was employed for scaling. Statistical tests (factor analysis and alpha coefficient) indicated that this research has a high construction validity and reliability. The research results indicated that cooperative functions toward fulfillment of members' demands were weak. The results of the path model indicated that effective factors on the success of cooperatives (from highest to the lowest) are: knowledge of cooperative principles by the members, extra-organizational factors, education quality, managers' skills, participation in cooperative affairs, and members' education level. Also, the success of cooperatives much relies on inter-organizational factors. The amount of members' share from education, participation in cooperative's affairs, the managers' specialty and skills, and knowledge of cooperatives' principles are very weak. Research results indicated that there is a direct and statistically significant correlation between these independent variables and the success of cooperatives in Isfahan province.
