The absence, in the biomass, of glutamic-oxalacetic and glutamic-pyruvic transaminases and the prevalance of gamma-glutamic transpeptidase were taken as basic criteria to differentiate between Erwinia carotovora var. carorovora from E. carotovora var, citrullis and E. toxica. For further identification, detection of cholesterol in the biomass confirmed the toxica species whereas the absence of glucose confirmed the citrullis variety.

A study of occlusal relationship and TMJ dysfunction, parafunctional relationship and TMJ dysfunction using PRI was investigated in 23 dental students without history of being treated, ranging from 19 to 24 years old. The author used Denar Pantronic and D5-A articulator to study above. The obtained results were as follows : 1. Distribution of PRI in experimental subjects was as follows. None 13%, Slight 43%, Moderate 40%, Severe 4% Prevalance of TMJ Dysfunction was 87% 2. PRI scores of occlusal group Aoi (less than 5 in Helkimo occlusion/articulation index) was $11.72\pm2.32$ , those of occlusal group Boi (more than 5 in Helkimo occlusion/articulation index) 23.0 $\pm$ 8.06. There was a significant difference between group Aoi and group Boi(P<0.01) 3. PRI scores of occlusal group Ald (no eccentric interference, less than 0.5mm in lateral shift of slide in centric) was 12.0 $\pm$ 2.49, those of occlusal group Bld(no eccentric interference, less than 0.5mm in lateral shift of slide in centric) 24.5$\pm$5.33 There was a significant difference between group Ald and group Bld(P<0.05) 4. Prevalance of parafunction subjects(%) was 65.2%. 5. PRI scores of parafunction group was 21.6 $\pm$ 9.48, those of nonparafunctional group 18.7 $\pm$ 9.06. There was not significant difference between parafunctional group and nonparafunctional group(P>0.1)

Turkey protects its entire population of 75 million people with all the MPOWER measures at the highest level. The aim of this study is to make a comparison of smoking and addiction data obtained from Sakarya University students in 2005-6 and 2012-13. A total of 4,200 (2,500 and 1,700 for each academic year) students at Sakarya University in Sakarya, Turkey, were randomly selected for sampling purposes. The selected participants represented Sakarya University students. Data were collected using a pretested anonymous and confidential, self-completed questionnaire which took 15-20 minutes to complete and Fagerstrom Test for nicotine dependence. Chi-squared, Spearman correlation, and binary logistic regression tests were used to define associations, if any. The level of significance was kept at alpha=0.05. Smoking prevalance dropped by 8.5% (from 26.9% to 18.5%). Male gender, older age, high family smoking index, low self-rated school success, and high peer smoker proportion were common variables that have correlation with smoking status. In the binary logistic regression test the highest contributor to "being a smoker" was found to be the rate of peer smokers. Having all friends smoking puts the student a a 47.5 and 58.0 times higher risk for smoking for males and females, respectively. Our results suggest an admirable diminution of smoking prevalance among Sakarya University students, which can be attributed to MPOWER protection.

In order to know morphological changes on the female genital organs by Ivermectin(IVM) administration, the histopathological observation was carried out in the organs of rat and mouse treated with the overdose of IVM. In the microscopical findings of the uterus, there were many mitotic figures, epithelial hyperplasia and papillary foldings in the endometrial surface. The increased prevalance of uterine glands, uterine epithelia and glands hyperplasia were markedly presented on diverse patterns adenoma-like structure and single nodular or multiple polyp-like adenoma. In ovary, primary and mature follicles were decreased in number, and hypoplasia of ovarian follicles, atretic follicles, follicular cysts and ovarian atropy were observed. It was considered that IVM administration resulted in follicular hypoplasia and atropy of ovary, and hyperplasia of uterine gland and endometrial surface epithelium might be transformed to neoplasia of glandular structures.

With the medical progress that has given spinal cord injured(SCI) individuals greater longevity and better overall health, chronic pain is emerged as major challenge in treating this population. According to past reports, estimates of prevalance of severe/disabling chronic pain in SCI patients have ranged from 18% to 63%. In etiologies of chronic pain in SCI patients, psychic or psychogenic pain categories should be included and more recent data have demonstrated that the persistant pain is directly related to higher levels of psychosocial distress and impairment. Recently, neurophysiological classification of the SCI pain syndrome into three etiologic groups(a; mechanical pain, b; radicular pain, c; deafferentation pain) is more frequently adopted for the classification of chronic SCI pain syndrome. The deafferentation pain is most common of the pain syndromes associated with SCI. After cervical epidural anesthesia for the surgical intervention of decubitus ulcer on the hip of two SCI patients, there were much reduction of existing chronic deafferentation character pain.

Mobile devices, such as PDAs, portable multimedia players, are more likely to encompass large storage devices with prevalance of high-quality multimedia contents. This paper proposes an object-based multimedia contents storage architecture that employs the object-based storage device model and the iSCSI protocol. It also provides a multimedia content player that operates directly with the proposed storage architecture. We implement both the proposed storage architecture and the multimedia content player upon the Linux environment. Performance evaluation by playing MP3 multimedia contents reveals that the proposed storage architecture reduces the total power consumption by 9%, compared with an existing networked storage. This enhancement is mainly contributed to the fact that a large portion of the file system is moved into the object-based multimedia contents storage from the mobile device.

Cystic Meningiomas are rare tumor. There is a clear prevalance in infants, according for $10{\sim}19%$ of all intracranial meningiomas in this age group, compared with only $2{\sim}4%$ in adults. But, reports of cystic meningioma have been increased in frequency since the introduction of computed tomography[CT] and magnetic resonance image[MRI]. Authors report two cases of cystic meningioma in adults. Radiological finding showed extraaxial mass with cystic component. Authors performed total surgical resection of the tumor mass and of the entire cystic component with cystic wall in both patients. Postoperative histopathological diagnosis of the tumor mass was a transitional meningioma in both patients. Both patients showed favorable prognosis and no recurrence findings in follow up MRI.

Sixty eight wild rats, Rattus norvegicus, were caught from Seoul city, Kyonggi, Kangwon, Cholla, and Kyongsang-provinces. All sera collected from rats were examined by immunofluorescent test to find antibody against murine typhus. The antibody prevalance to murine typhus was 4.4%(3/68). Sero-positive rate was 12.5%(2/16) in Kyonggi province and 12.5%(1/8) in Cholla province. The sero-positive rate difference between sexes of rats was not recognized. Three Rattus norvegicus having antibody to murine typhus were morphologically classified as subadult with 8.3%(1/12), middle-aged adult with 5.9%(1/17), and old adult with 4.8%(1/21), respectively.
