  • This article reports changes in the mechanical properties of chromium steel after nitrogen implantation at high temperature. The samples are implanted with 120keV N-ion at doses ranging from $1\times1080$ to $4\times1080ions/cm^2$ and at substrate temperature ranging from 25 to $400^{\circ}C$. Nano-hardness and AES(Auger electrons spectroscopy) were measured from nitrogen ion implanted layer. The sliding wear and impact wear properties of the implanted samples were also measured. The results revealed that the hardness and mechanical properties of ion implanted samples depend strongly on the ion doses and implantation temperature. The hardness of the nitrogen implanted sample with 120keV, $4\times10^{18}ions/cm^2$, $335^{\circ}C$ was measured to be approximately 20 GPa, which is approximately 5 times higher than that of un-implanted sample (H=3.8 GPa). Also, the sliding wear and impact wear properties of nitrogen implanted samples were greatly improved. Detailed experiment results will be presented.

  • The clinical use of several endosseous oral implants designs has become highly predictable in recent decades. Implant success critically depends both on the vertical and horizontal dimensions of the prospective host site and on the quality of the local bone. Implants shorter than 10 mm can be a long-term solution for sites with limited bone height. This article describes theoretical characteristics and clinical outcome of short implants through a medline search. When surgical preparation is related to bone density, textured-surfaced implants are employed, operators' surgical skills are developed, and indications for implant treatment duly considered, the survival rates for short implants has been found to be comparable with those obtained with longer implants.

  • The current understanding of the mechanisms of pharmacotherapy for depression is characterized by an emphasis on increasing synaptic availability of serotonin, noradrenaline, and possibly dopamine, while minimizing side effects. The acute effects of current available effective antidepressants include blocking selective serotonin or noradrenaline reuptake, alpha2 autoreceptors or monoamine oxidase. Although efficacious, current treatments often produce partial or limited symptomatic improvement rather than remission. While current pharmacotherapies target monoaminergic systems, distinct neurobiological underpinnings and other systems are likely involved in the pathogenesis of depression. Recently, several promising hypotheses of depression and antidepressant action have been formulated. These hypotheses are largely based on dsyregulation of neural plasticity, CREB, BDNF, corticotropin-releasing factor, glucocorticoid, hypothalamic-pituitary adrenal axis and cytokines. Based on these new theories and hypotheses of depression, a number of new and novel agents, including corticotropin-releasing factor antagonists, antiglucocorticoids, and substance P antagonists show a considerable promise for refining treatment options for depression. In this article, the current available pharmacotherapies, current understanding of neurobiology and pathogenesis of depression and new and promising directions in pharmacological research on depression will be discussed.

  • As fashion brand logos have been used conspicuously, they have been recognized as a part of the product design. Since the 2000s, fashion designers have actively begun to apply fashion brand logos to product designs by transforming, patterning, and distorting, so the importance of fashion brand logos were emphasized. This article has attempted to establish the implications between fashion brand personality and the motif which is applied to a fashion brand logo. 27 of fashion brand logos were chosen because they are easy to access and have a history of more than 10 years. As a result, these 27 logos were categorized into 5 animal motifs: a horse, a bird, a snake, a dog and a tiger. In recent years, numerous studies have found that the appearance and behavior of an animal affects their symbol system which is recognized by humans. To deduce the symbolism which is communicated by a brand logo, archetypical symbols of 5 animals were analyzed as mentioned and the brand personality and image of 27 brands. As a result, there are implications between the archetypical symbol of animal motifs and a brand image and brand personality. A majority of the adjectives which express the archetypical symbolism of animal motifs as well as brand image and brand personality are similar. Moreover, the personalities of fashion brands categorized by animal motifs are different from each other, so how each animal motif communicates different images and symbols was explored.

  • Interface tracking of two phase is significant to analyze multi-phase phenomena. The VOF(Volume of Fluid) and level set are well known interface tracking method. However, they have limitations to solve compressible flow and incompressible flow at the same time. CIP(Cubic Interpolate Propagation) method is appropriate for considering compressible and incompressible flow at once by solving the governing equation which is divided up into advection and non-advection term. In this article, we analyze the droplet impingement according to various We number using improved CIP method which treats nonlinear term once more comparison with original CIP method. Furthermore, we compare spread radius after droplet impingement on the wall with the experimental data and original CIP method. The result using improved CIP method shows the better result of the experiments, comparison with result of original CIP method, and it reduces the mass conservation error which is generated in the numerical analysis comparison with original CIP method.

  • Background: Colorectal cancer (CRC) is the commonest malignancy in the lower gastrointestinal tract in both men and women. It is the third leading cause of cancer-dependent death in the world. In Iran the incidence of colorectal cancer has increased during the last 25 years. Materials and Methods: In this article we analyzed the survival of 447 colorectal patients of Taleghani hospital in Tehran using parametric competing-risks models. The cancers of these patients were diagnosed during 1985 - 2012 and followed up to 2013. The purpose was to assess the association between survival of patients with colorectal cancer in the presence of competing-risks and prognostic factors using parametric models. The analysis was carried out using R software version 3.0.2. Results: The prognostic variables included in the model were age at diagnosis, tumour site, body mass index and sex. The effect of age at diagnosis and body mass index on survival time was statistically significant. The median survival for Iranian patients with colorectal cancer is about 20 years. Conclusions: Survival function based on Weibull model compared with Kaplan-Meier survival function is smooth. Iranian data suggest a younger age distribution compared to Western reports for CRC.

  • Pregnancy and puerperium are associated with significant changes in pschological and physiologic health status. Back and pelvic pain is common in pregnancy with prevalence figures in the range of $48\%-90\%$. The pain starts during pregnancy and often disappears soon after childbirth. But the prevalence of such pain four to six months post postpartum is report to be $25-40\%$. In $10-15\%$ of the case the pain become chronics, that is persisting for more than three months after childbirth. Low back pain and pelvic pain maybe caused by several factors related to changes that occur naturally during pregnancy. Changes in the center of gravity can create a strain on weight-bearing structures in bone. Pregnancy related hormones, relaxin, create general laxity of collagenous tissue. Another factor found to be a possible primary or contributing cause for law back and hip symptoms are leg length inequality, weight gain and changes in foot function. This article outlines the physiological and biomechanical changes that occur during pregnancy which have been reported to be possible causes of low back and pelvic pain And then, examination, diagnosis, evaluation and treatment of the woman during pregnancy are described. Standard treatment for low back pain and pelvic pain in pregnancy includes education in anatomy and kinesiology, back-strengthening exercise, training of the abdominal muscles and body posture correction. So, most woman during pregnancy require individual consultation and physiotherapist.

  • Ministry of Environment has been promoting BTL business of the sewer rehabilitation which continues from 2005 up to now. Sewer rehabilitation is classified into three parts : wastewater pipe rehabilitation, rainwater pipe rehabilitation and drainage equipment rehabilitation. Drainage equipment rehabilitation is that drainage pipe connects wastewater pipe directly without water-purifier. In the drainage equipment construction, it is inevitable to have the damage of ground structures(wall, gate and U drain, etc) when an open excavation method is used. Therefore it is necessary to develop non-excavation method to connect drainage pipe and wastewater pipe like jacking method to avoid the damage of ground structure. This paper has conducted an analysis of the non-excavation method using a boring machine attached to backhoe, which is issued the verification certificate of environmental technology according to the Development of and Support for Environmental Technology Act, article.7. The index set in this analysis was sectionalized to the condition of construction, the grade of drainage pipe, the size of excavated hole, the amount of waste cement concrete and asphalt concrete and the benefit effect compared to open excavation method.

  • Condylar fractures account for one-third of all mandibular fractures. There are many surgical methods for the open reduction of condylar fractures, such as the transoral, submandibular, preauricular, and retromandibular approaches. Two patients suffering from condylar fractures, a 45-year-old man and a 25-year-old man, were admitted to our hospital. Both patients' condylar fractures were positioned too high for us to use the transoral approach. Therefore, we employed the retromandibular method to expedite the approach to the fracture site and minimize the size of the incision. After the surgical procedures in both cases, we experienced complications in the form of parotid gland fistulae, which rarely result from the retromandibular approach. A combination of botulinum toxin injection and amitriptyline medication was effective for the management of these parotid gland fistulae. Here, we report these two cases and offer a review of the literature on this article.
