    In todayā€™s business environment all business operations are enabled by technology. Its always on and connected nature has brought new business possibilities but at the same time has increased the number of potential threats. Information security has become an established discipline as more and more businesses realize its value. Many surveys have indicated the importance of protecting valuable information and an important aspect that must be addressed in this regard is information security awareness. The human component has been recognized to have an important role in information security since the only way to reduce security risks is through making employees more information security aware. This also means that employees take responsibility of their actions when dealing with information in their everyday activities. The research is concentrated mainly on information security concepts alongside their relation to the human factor with evidence that users remain susceptible to information security threats, thus illustrating the need for more effective user training in order to raise the level of security awareness. Two surveys were undertaken in order to investigate the potential of raising security awareness within existing education systems by measuring the level of security awareness amongst the online population. The surveys analyzed not only the awareness levels and needs of students during their study and their preparation towards entering the workforce, but also whether this awareness level changes as they progress in their studies. The results of both surveys established that the awareness level of students concerning information security concepts is not at a sufficient level for students entering university education and does not significantly change as they progress their academic life towards entering the workforce. In respect to this, the research proposes and develops the information security toolkit as a prototype awareness raising initiative. The research goes one step further by piloting and evaluating toolkit effectiveness. As an awareness raising method, the toolkit will be the basis for the general technology user to understand the challenges associated with secure use of information technology and help him assess its current knowledge, identify lacks and weaknesses and acquire the required knowledge in order to be competent and confident users of technology.The American College of Greec

    BACKGROUND: Sexual behaviour is a major determinant of sexual and reproductive health. We did a National Survey of Sexual Attitudes and Lifestyles (Natsal 2000) in 1999-2001 to provide population estimates of behaviour patterns and to compare them with estimates from 1990-91 (Natsal 1990). METHODS: We did a probability sample survey of men and women aged 16-44 years who were resident in Britain, using computer-assisted interviews. Results were compared with data from respondents in Natsal 1990. FINDINGS: We interviewed 11161 respondents (4762 men, 6399 women). Patterns of heterosexual and homosexual partnership varied substantially by age, residence in Greater London, and marital status. In the past 5 years, mean numbers of heterosexual partners were 3.8 (SD 8.2) for men, and 2.4 (SD 4.6) for women; 2.6% (95% CI 2.2-3.1) of both men and women reported homosexual partnerships; and 4.3% (95% CI 3.7-5.0) of men reported paying for sex. In the past year, mean number of new partners varied from 2.04 (SD 8.4) for single men aged 25-34 years to 0.05 (SD 0.3) for married women aged 35-44 years. Prevalence of many reported behaviours had risen compared with data from Natsal 1990. Benefits of greater condom use were offset by increases in reported partners. Changes between surveys were generally greater for women than men and for respondents outside London. INTERPRETATION: Our study provides updated estimates of sexual behaviour patterns. The increased reporting of risky sexual behaviours is consistent with changing cohabitation patterns and rising incidence of sexually transmitted infections. Observed differences between Natsal 1990 and Natsal 2000 are likely to result from a combination of true change and greater willingness to report sensitive behaviours in Natsal 2000 due to improved survey methodology and more tolerant social attitudes

    Treatment for Multiple Aspergillus Spondylitis Including a Hip Joint

    Multiple aspergillus spondylitis (AS) is a life threatening infection that occurs more commonly in immunocompromised patients, and is commonly treated with antifungal agents. However, there is relatively little information available on the treatment of multiple AS. The authors encountered a 46-year-old man suffering from low back and neck pain with radiculomyelopathy after a liver transplant. The patient had concomitant multiple AS in the cervico-thoraco-lumbar spine and right hip joint, as confirmed by radiologic imaging studies. The pathological examination of a biopsy specimen revealed fungal hyphae at the cervical and lumbar spine. Anterior decompression and interbody fusion were performed for the cervical and lumbar lesions, which showed instability and related neurological symptoms. Additional antifungal therapy was also performed. The patient was treated successfully with remission of his symptoms

    Federico di Montefeltro's hyperkyphosis: a visual-historical case report

    Get PDF
    <p>Abstract</p> <p>Introduction</p> <p>The literature contains several publications describing the use of visual arts to develop observational skills in medical students. Portraits of individuals of the Italian Renaissance can be used to enhance these skills and stimulate the development of differential diagnoses in medical students. The Duke of Urbino, Federico di Montefeltro (1422ā€“1482), lost his right eye and nasal bridge during a jousting accident in 1450. Consequently, almost every profile of him in existence today depicts his face in a left lateral view. Although some authors have described the Duke's missing nasal bridge, none have described his prominent thoracic hyperkyphosis, which is clearly discernible in two paintings by Piero della Francesca. The purpose of this report is to describe the Duke's hyperkyphosis, develop relevant differential diagnoses, and suggest a possible etiology of the convexity.</p> <p>Case presentation</p> <p>We have examined two paintings of the Duke by Piero della Francesca ā€“ the diptych, <it>The Duke and Duchess of Urbino </it>(1465), and the <it>Madonna of the Egg </it>(1472). A MEDLINE search revealed 2 articles that were relevant to this study. This search was complemented by a search of the collection at the library of Seton Hall University, and the first author's experience studying at the University of Urbino. The historical data obtained from these searches were incorporated with the visual analysis to formulate a plausible etiology of the Duke's thoracic hyperkyphosis.</p> <p>Conclusion</p> <p>Differential diagnoses of the Duke's thoracic hyperkyphosis include Scheuermann disease, osteoporosis, and trauma-related spinal changes. Based on the available evidence, the Duke's thoracic hyperkyphosis could have been caused by repetitive trauma to the spine due to numerous hours on horseback with heavy armor. The role that osteoporosis played in the development of the hyperkyphosis is unclear, as is whether the Duke had the convexity during childhood. The hyperkyphosis as a stylistic variant by Piero della Francesca is unlikely. This report is an example of a teaching strategy that can be used to enhance the observational skills of medical students in evidence-based medical education.</p

    Study Design A prospective comparative study. Purpose To describe the changes in the spinopelvic parameters on normal Koreans more than 50 years of age. Overview of Literature There are differing opinions regarding the changes in the thoracic kyphosis, lumbar lordosis, C7 plumb with age in the elderly population. Methods Sagittal standing radiographs of the whole spine including the pelvis in 132 Korean adult male volunteers more than 50 years of age were evaluated prospectively. Volunteers with a history of spine operation, spinal disease, pain in their back or legs, scoliosis, spondylolisthesis, monosegment disc space narrowing, or compression fracture in radiographs were excluded. The following parameters were included: thoracic kyphosis (T5 upper end plate [UEP]-T12 lower end plate [LEP]), thoracolumbar kyphosis (T10 UEP-L2 LEP), lumbar lordosis (T12 LEP-S1 UEP), lower lumbar lordosis (L4 UEP-S1 UEP), sacral slope, pelvic incidence, and the distances from the C7 plumb to the posterosuperior endplate of S1. These parameters in the 6th, 7th and 8th decade groups were compared and the changes in these parameters according to age were examined. Results The thoracic kyphosis demonstrated significant differences in the in the three age groups (p = 0.019), and increased with age (r = 0.239, p < 0.006). The other parameters did not show any significant difference or correlation. Conclusions Similar global sagittal balances and spinopelvic parameters may be observed in Korean males older than 50 years, with a trend towards increasing thoracic kyphosis with age

    One-year Outcome Evaluation after Interspinous Implantation for Degenerative Spinal Stenosis with Segmental Instability

    The authors hypothesized that the placement of the interspinous implant would show a similar clinical outcome to the posterior lumbar interbody fusion (PLIF) in patients having spinal stenosis with mild segmental instability and that this method would be superior to PLIF without significantly affecting degeneration at the adjacent segments. Forty two adult patients having degenerative spinal stenosis with mild segmental instabilit who underwent implantation of Coflexā„¢ (Spine motion, Germany) or PLIF at L4-5 between January 2000 and December 2003 were consecutively selected and studied for one-year clinical outcome. At 12 months after surgery, both groups showed a significant improvement in the visual analogue scale score and Oswestry disability index score for both lower extremity pain and low back pain. However, the range of motion at the upper adjacent segments (L3-4) increased significantly after surgery in the PLIF group, which was not manifested in the Coflexā„¢ group during the follow-up. The authors assumed that interspinous implantation can be an alternative treatment for the spinal stenosis with segmental instability in selected conditions posing less stress on the superior adjacent level than PLIF
