Temporal bone fracture is usually the result of blunt head injury as ossicular disruption or isolated dislocation of individual ossicles may occur after temporal bone trauma. The incus is particularly prone to displacement because of its fragile ligamentous support. We report a rare case of incus dislocation into the external auditory canal associated with an underlying temporal bone fracture.

Although marketing researchers have explored the value of relationship resources for pricing, distribution, and promotions, theory and research on the impact of relationship marketing strategies on product management has largely been ignored. Relationship marketing research has not considered the role of commitment and trust, the key relationship variables, on consumers' likelihood of adoption. Therefore, to explore this issue, the authors propose and test a three‐stage model through a series of structural equations. The results show that the ability to predict the likelihood of new product adoption in two distinct industries significantly increases when, in addition to characteristics of the adopter and the product, consumer commitment to and trust in the firm or brand that introduces the product are considere

In this paper, an algorithm for fault location in Auto Transformer (AT) Feeding Railway system is presented. If a fault occurs at the AT feeding circuits of electrical railway system, it is very important to find fault location and to remove it immediately for the purpose of ensuring safety for transportation. Because the characteristics of reactance - distance are not linear, only using one terminal signals to give fault distance is difficult. In this paper, first, using the KVL, 4 voltage equation are obtained. Secondly, eliminatillg voltage a distance equation which consists of currents at rail and line parameters including mutual effects.

Purpose: Abdominoperineal resection (APR) has been regarded as the standard procedure for the treatment of distal rectal cancer since Miles first described it in 1908. But because of the better understanding of the patterns of spreading tumor, the pelvic physiology, the development of stapling devices and introduction of total mesorectal excision (TME), the rate of sphincter preserving surgery has been increasing. The aim of this study is to compare the oncologic outcomes after laparoscopic APR and ultra-low anterior resection with hand- sewn coloanal anastomosis (CAA) for treating distal rectal cancer. Methods: Between January 2003 and October 2007, 95 patients who were followed up for more than 2 years after curative laparoscopic APR or CAA for distal rectal cancer were included in this study. The clinical characteristics, pathologic findings, postoperative complications and oncologic results were retrospectively analyzed. Results: There were 31 APRs and 64 CAAs. The median follow-up period was 43 (5∼79) months. The mean distance between the lower margin of the tumor and the anal verge was 2.1±1.2 cm in APR and 3.7±1.4 cm in CAA (p<0.001). There were 2 (6.5%) local recurrences and 8 (25.8%) systemic recurrences after APR and 3 (4.7%) local recurrences and 10 (15.6%) systemic recurrences after CAA, respectively (p=0.641, p=0.161). The 3-year disease-specific survival rate was 86.7% in APR and 93.5% in CAA (p=0.407). The 3-year disease free survival rate was 73.7% in APR and 80.1% in CAA (p=0.161) but there were no significant differences in the oncologic results according to the stages between the two groups. Conclusion: The operative procedures are changing toward sphincter preservation. Laparoscopic ultra-low anterior resection and hand-sewn coloanal anastomosis is oncologically as safe as laparoscopic APR for treating lower rectal cancer. However, APR should be considered the standard treatment for distal rectal cancer when it invades the anal sphincter or the levator ani.

It is appropriate and useful to interpret some product classification schemes as buyer behavior models; such classifications permit investigations of discrepancies between classification predictions and actual buyer behavior. We review existing product classifications and identify underlying behavioral assumptions of various classification schemes that have been used in the marketing discipline for more than nine decades. Recognizing the irrelevance of existing product classifications for current products, we propose a new reclassification framework by incorporating transparency concepts. Based on this extended product classification, we highlight the potential roles of product classification study as an important link between consumer research and marketing strategy, emphasizing behavioral implications.
