Background: Today, obesity is a key healthcare problem on a global scale including Iran. The present study aimed at determining the prevalence of overweight and obesity in Hormozgan province, Iran to propose effective healthcare programs and strategies to reduce this dilemma in future. Objectives: The current study conducted in the South of Iran aimed at exploring the prevalence of overweigh and obesity in males and females in terms of social variables affected by demographic variables such as age, gender, marital status, education level, smoking, and physical activity. Methods: In the current cross sectional, observational study, a sample of 5000 eligible males and females above 18 years old were selected based on a multi-stratified clustering sampling method. The data were collected by a researcher-made questionnaire consisting of variables such as weight, height, drug consumption, and physical activity. Statistical analysis was performed. Results: The present study findings revealed that 31. 8% of the population in Hormozgan province was overweight, while only 15. 2% were obese. The highest percentage of obesity (18. 3%) was observed among the subjects aged 35-44 years. The prevalence of obesity among females was higher in urban population. Conclusions: The current study results showed that the urban married middle-aged females had the highest rate of obesity, which requires appropriate educational planning and utilization of efficient models in the realm of females’ health.

Background: During the last decade, increased rates of drug traffic have led the smugglers to use various methods. One of these methods of illicit drug smuggling is body packing. Smuggling by intra-abdominal concealment is called "body packing". In this research, mortality rate was investigated due to body packing in Tehran.Methods: A descriptive study (case series) was designed on all corpses referred to the Forensic Medicine Organization of Tehran between April 1999 - December 2000. Demographic data such as sex, age, marital status, addiction, job, education level, type of opioid and the weight, number of packets, and results of blood and urine morphine tests by thin-layer chromatographic method were investigated. Results: Continental system of law is used in Iran and 0.06% of the referred corpses to Forensic Medicine Organization of Tehran were body packers. There were 12 cases, all of them were men. The mean age of body packers was 43 years (range 20 – 62). The minimum weight of the packets was 20 g and the maximum weight was 1400 g (mean = 501 g). The minimum number of the packets was one and the maximum number of the packets was 48. Twenty five percent of the corps were putrefied and one corpse was mummified. None of the body packers had academic education nor were employed. Nine of them lived in cities. Twenty five percent of them were intravenous addicts. The corpses were found mostly in terminals (17%), roads (58%), and cities (25%). Conclusion: Hospital physicians may neglect this type of gastrointestinal foreign body if they are not aware of the body packer syndrome. Body packing should be suspected in anyone with signs of drug-induced toxic effects after a recent arrival on city terminals or when there is no history of recreational drug use.

The traditional event tree analysis uses a single probability to represent each top event. However, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. The fuzzy set theory is universally applied to deal with this kind of phenomena. The main purpose of this study is to construct an easy method to evaluate human errors and integrate them into event tree analysis by using fuzzy concepts. A systematic fuzzy event tree analysis algorithm is developed to evaluate the risk of a largescale system. A practical example in of offshore oil pipeline is used to demonstrate this procedure.

Logical realism, in a sense, is realism about the subject matter of logic. What is logic really about? Talk of logic is more or less synonymous with talk of the relation of logical Consequence; the relation that holds between the premisses of an argument and its conclusion. However, in the history logic, this has not always been the case. Before placing logical Consequence at the heart of logic, the Frege-Russell view was dominant in the philosophical community; a view according to which logic is primarily about logical truths. In this paper, we argue that logic is about logical Consequence and not logical truth. Then we list a couple of motivations for investigating a metaphysics of logic. Proponents of logical realism typically base their theories upon logical truths as logical facts. In this article, we aim to turn the emphasis from logical truths to logical Consequence(s) as the primary object(s) of logical realism and give a general outline on how to be a realist about logical Consequence.
