How Do Patrons Search the Online Catalog When No One's Looking? Transaction Log Analysis and Implications for Bibliographic Instruction and Systems Design.

Eleven public access terminals at the University of Colo rado (CU) Libraries were monitored electronically to pro duce transaction logs that were used to gather statistics and analyze users' behavior when searching online catalogs. Other studies have surveyed user opinions about searching online, whereas this study records user behavior unobtru sively and focuses exclusively on what actually is occurring during the search process. Several comparisons have been made with previous transaction log studies. Among other findings: 1. Use of system-supplied search aids varies, from low use of quick search and express search features, to more extensive use of search history and searching databases other than the home catalog. 2. Analysis of search results reveals that 66% of subject (keyword) and name searches produce ten or fewer re sults, and 82% produce twenty-five or fewer titles, a manageable number for searchers to scan postings and spot relevant materials. 3. User persistence in scanning title lists is high at CU, with the full list being requested for nearly 40 % of the searches which net up to one hundred results. 4. Overall, results show that emphasis on improved sys tem design must be stressed if the needs of the majority of searchers are to be met more effectively.
An Investigation of Seventh Grade Students’ Performances on Conceptual, Procedural and Graphical Problems Regarding Circles

The purpose of this study is to determine seventh grade students’ preferences among the procedural, conceptual and graphical questions in the subject of circles, to define their success levels in their preferences, and to compare students’ success levels in one question type with their performances in other question types. The methodology adopted during this research was case study. Based on criterion-based purposive sampling strategy, 98 middle school students were selected as the participants. Data were collected through an achievement test consisting of nine questions (three per question type). The results obtained from the study indicated that students mostly preferred graphical question types. Moreover, majority of students could not succeeded high levels in their preferred question types. In addition, the students performed better in graphical question types; however, the failure in procedural question types was remarkable. Keywords: Multiple representations, middle school students, mathematics education, circles
Fiber-optic microcellular communication system using frequency modulated LD and optical discriminator and its nonlinear distortion suppression

This paper discusses the transmission quality in the fiber optic microcellular communication system using a directly modulated laser diode and optical frequency discriminator. A new theoretical approach is used to describe the interaction between the nonlinearities of the directly frequency modulated laser diode and optical frequency discriminator, and the carrier to noise plus distortion ratio is theoretically analyzed. The results show that the receiver sensitivity can be improved by 3 dB using a Mach-Zehnder type frequency discriminator and balanced mixing photodetector. Furthermore, it is clarified that 3rd order intermodulation distortion is effectively suppressed due to the interaction between the laser diode and discriminator nonlinearities. This feature can be applied to adaptive post-distortion nonlinear compensation in the radio-over-fiber FM link.
Quality of methodological design and level of research articles published by occupational therapists in Iranian scientific journals

Abstract This descriptive study aimed to investigate the quality of methodological design, level of evidence, and practice area of research articles published by Iranian occupational therapists in Iranian non-occupational therapy scientific journals. All research articles in 10 Iranian scientific journals between 2004 and 2010 were reviewed by two independent occupational therapists. During this period Iranian occupational therapists published 52 articles in these journals. Holm’s (2000) classification system was employed to identify the level of evidence for each article. While the randomized controlled trials studies (level II) were the highest number of the published research articles (29%; n=15), there were no systematic reviews published in the included journals. Pediatric and school based articles were the most commonly researched practice area (45%; n=23). The least researched topic was older people (6%; n=3) the levels of methodological research represented in the articles are similar to studies published elsewhere. However, the number of publications is less than American’xs studies, especially in the area of mental health and older people.
Endosymbiotic bacteria of the boar louse Haematopinus apri (Insecta: Phthiraptera: Anoplura)

Insects exclusively feeding on vertebrate blood are usually dependent on symbiotic bacteria for provisioning of B vitamins. Among them, sucking lice are prominent in that their symbiotic bacteria as well as their symbiotic organs exhibit striking diversity. Here we investigated the bacterial diversity associated with the boar louse Haematopinus apri in comparison with the hog louse Haematopinus suis. Amplicon sequencing analysis identified the primary endosymbiont predominantly detected from all populations of H. apri with some minor secondary bacterial associates. Sequencing and phylogenetic analysis of bacterial 16S rRNA gene confirmed that the endosymbionts of the boar louse H. apri, the hog louse H. suis and the cattle louse Haematopinus eurysternus form a distinct clade in the Gammaproteobacteria. The endosymbiont clade of Haematopinus spp. was phylogenetically distinct from the primary endosymbionts of other louse lineages. Fluorescence in situ hybridization visualized the endosymbiont localization within midgut epithelium, ovarial ampulla and posterior oocyte of H. apri, which were substantially the same as the endosymbiont localization previously described in H. suis and H. eurysternus. Mitochondrial haplotype analysis revealed that, although the domestic pig was derived from the wild boar over the past 8,000 years of human history, the populations of H. apri constituted a distinct sister clade to the populations of H. suis. Based on these results, we discussed possible evolutionary trajectories of the boar louse, the hog louse and their endosymbionts in the context of swine domestication. We proposed ‘Candidatus Haematopinicola symbiotica’ for the distinct clade of the endosymbionts of Haematopinus spp.
The role of alemtuzumab in the treatment of chronic lymphocytic leukemia (CLL) and the achievement of minimal residual disease negativity in relapsed/refractory CLL

Chronic lymphocytic leukemia (CLL) is the most common adult hematologic malignancy in the developed world, predominantly affecting the elderly. It is a disease with a very heterogeneous outcome, with some patients surviving for many years without any evidence of progression and others rapidly developing aggressive disease, associated with early bone marrow failure and repeated infections. In recent years, the recognition of novel prognostic markers (e.g. mutational status of the variable region of the immunoglobulin heavy-chain gene [VH],1-4 zeta-associated protein 70 [ZAP70],5-8 and p53 deletion or mutation resistance)9-10 has greatly improved the stratification of patients on the basis of their clinical risk profile, allowing treatment to be tailored accordingly, particularly in patients likely to develop progressive disease.

Ingestion of Salmon Nasal Cartilage-Derived Proteoglycan Improves Skin Condition: A Randomized, Double-Blind, Controlled Study

Background: Proteoglycan is one of the components of the extracellular matrix with various biological activities and has been used as the functional foods to improve knee joint health or skin condition. Objective: To examine the effect of ingestion of salmon (Oncorhynchus keta, Salmonidae) nasal cartilage-derived proteoglycan (sPG) on skin condition, we performed a randomized, double-blind, controlled study in healthy adult volunteers. Methods: Recruited subjects (n=156) were men and women, ages 21-62 years. From this population, we selected 19 subjects based on the exclusion criteria of the guidelines for evaluation of cosmetic functions of Japanese Cosmetic Science Society. Subjects were randomly divided into an sPG group (n=10; mean age, 39.1 years) and a placebo group (n=9; mean age, 39.6 years). The characteristics of the sPG used in this study were assessed by HPLC and electrophoresis analysis. Results: The safety was confirmed by the monitoring of all volunteer subjects for the development of adverse reactions. We found no negative information on the safety of proteoglycan ingestion and no evidence for an interaction between proteoglycan and other functional foods/medicine in several different databases. Viscoelasticity and recovery after deformation as the skin elasticity increased significantly in the sPG group compared to the placebo group (p<0.05). Skin looseness significantly decreased in the sPG group (p<0.05). Moreover, the number of wrinkles, conspicuous or darkened facial pores, and blotches significantly decreased in the sPG group (p<0.05). Measurements of skin conductance showed that sPG improved skin moisture and micrographs of facial corneocytes showed that sPG improved rough skin. Conclusion: Our results suggest the potential of sPG as a food ingredient to improve human skin condition, including skin elasticity, wrinkles, facial pores, blotches, moisture, and smoothness.
Capturing and analyzing internet worms

This document is about malware analysis, with a particular focus on exploit-based Internet worms that spread from one host to another over the network by exploiting a software vulnerability in the new host being attacked. Based on our experiences analyzing real worms that use this method of worm propagation we develop a model that divides this attack into three stages: the exploit vector (e) where the machine being attacked is still running its vulnerable code, the bogus control data (γ) that is the part of the attack that is directly involved in control flow hijacking, and the payload (π) where the worm code is being executed instead of the code of the attacked system. The Epsilon-Gamma-Pi model will be defined more formally in Chapter 3. In this document the particular focus will be on control data attacks, but the model generalizes to hijacking of control flow at any level of abstraction. What we will show in this dissertation is that malware analysis put into the context of the Epsilon-Gamma-Pi model can take advantage of various limitations placed on the worm at each of the stages. Researchers and malware analysis professionals can benefit greatly from an understanding of the differences between the stages in terms of the adversarial model, the polymorphic and metamorphic techniques to evade signature detection, and the amount of information about the threat that can be discovered in a particular stage. Three specific examples are described in detail: Minos, an architectural mechanism to catch control data attacks in the γ stage; DACODA, a tool to analyze attack invariants that limit polymorphism in the e stage; and Temporal Search, a method to analyze the π stage and discover timebomb attacks in a worm's payload.
Registro de enfermedades respiratorias de origen laboral en Navarra Registry of occupational respiratory diseases in Navarre

BACKGROUND: In January 2002 an occupational respiratory diseases record was established in Navarre so that the number and characteristics of the occupational respiratory pathology could be analysed. METHODS: The cases reported by doctors who collaborated in 2002, 2003 and 2004, were entered in a database for subsequently analysis. This database has several variables: gender, age, tobacco habit, hospital department and notifying doctor, diagnosis, job and causal agent. RESULTS: 125 cases were reported. 97 males (77.6%) and 28 females (22.4%). Average age was 55,4 years old. Eighty-eight were non-smokers (70.4%) and 37 were smokers (29.6%). Pneumology reported 84 cases (67.2%) and Allergology 41 (32.8%). The diagnoses were: 50 bronchial asthma (40%), 31 benign pleural disease (24.8%), 8 extrinsic allergic alveolitis (6.4%), 8 mesothelioma (6.4%), 7 bronchopulmonary cancer (5.6%), 5 acute inhalations (4%), 3 amianthinopsy (2.4%), 2 rhinitis (1.6%), 1 RADS (0.8%) and 1 COPD (0.8%). The most reported jobs were: 13 painting and varnishing (10.4%), 12 spinning asbestos yarn (9.6%) and 8 bakery and confectionery (6.4%). The main causal agents were: 49 cases of asbestos (39.2%), 15 isocyanates (12%) and 8 silica (6.4%). CONCLUSIONS: The most frequent pathology was bronchial asthma, followed by benign pleural disease. The most reported job was painting and varnishing and secondly spinning asbestos yarn. Asbestos was the first substance involved and the second was isocyanates. Most of the patients were males and non-smokers. The Pneumology Service of the Virgen del Camino Hospital reported most of the cases. Ratio contrast analysis showed a certain tendency towards a statistical significance in rhinitis, occupational asthma and amianthinopsy.

An investigation of student teachers' teaching of difficult ideas in chemistry

It is not surprising that, in view of the conceptual and theoretical nature of chemistry, there are many ideas in chemistry that pupils find difficult. A review of the work in this area shows an extensive body of literature in which pupils' misunderstandings of key ideas in chemistry in the 12 15 age range are documented. However, much of this research does not give any assistance in terms of the development of teaching strategies or implementation of intervention packages. In fact, it appears from the literature that comparatively little research has been carried out into how student teachers teach ideas in those areas of chemistry where misunderstandings arise. This study investigated how student teachers draw on the guidance they are given in their training course about dealing with pupils' misunderstandings in chemistry. The project is a case study of practice in one institution and is also characterised by aspects of an action research project. A baseline study was carried out to establish a benchmark of current practice among student teachers. This was followed by the development and implementation of an Intervention Package to assist a second group of student teachers in teaching these difficult ideas. Data were gathered by means of classroom observation, questionnaires, interviews and analysis of lesson plans. A theoretical framework was developed to assist in the analysis of the baseline data and the post-intervention data. Models of educational evaluation were used to develop a strategy for assessing the effectiveness of the Intervention Package. The results of this assessment indicate that the Intervention Package was successful in a number of areas, e. g. increasing the awareness of the student teachers of the problems involved in teaching difficult ideas, encouraging the student teachers to use particular types of resources in their teaching, helping them to develop new teaching strategies and encouraging them to foster a greater climate of understanding in the classroom. The attitude of the student teachers towards the material covered in the Intervention Package was found to be very positive since they viewed this material as a practical strategy to help their teaching of difficult ideas in chemistry.
Association of Spiritual Health and Quality of Life in the Hemodialysis Patients Admitted in Shahid Motahari Hospital in Jahrom, Iran (2016)

Background & Aims: Impaired performance and poor quality of life may deteriorate the psychological health of the patients undergoing hemodialysis. Spiritual behaviors, especially bonding with God, could improve spiritual energy and create a positive attitude in these patients. The present study aimed to assess the association between spiritual wellbeing and quality of life in hemodialysis patients. Materials & Methods: This descriptive-analytical study was conducted on 82 hemodialysis patients in the Hemodialysis Center of Motahari Hospital in Jahrom, Iran in 2016. The subjects were selected via convenience sampling. Data were collected using the quality of life questionnaire for renal patients and the spiritual wellbeing scale by Paloutzian and Ellison. Data analysis was performed in SPSS version 20 using descriptive (mean and standard deviation) and inferential statistics (Pearson’s correlation-coefficient). Results: Positive, significant correlations were observed between the dimensions of quality of life, including physical functioning (0.222), role impairment due to emotional problems (0.260), energy/fatigue (0.393), general health (0.394), and physical health (0.293), and domains of spiritual wellbeing. Conclusion: According to the results, it is critical to enhance spiritual wellbeing as an important influential factor in the quality of life of individuals. Paying attention to the key role of spiritual health in a country like Iran, where cultural values and religious beliefs prevail, could be beneficial in developing effective healthcare programs for hemodialysis patients.
Assessment of time interval between tramadol intake and seizure and second drug-induced attack

Background: Tramadol is a synthetic drug which is prescribed in moderate and severe pain. Tramadol overdose can induce severe complications such as consciousness impairment and convulsions. This study was done to determine the convulsions incidence after tramadol use until one week after hospital discharge. Methods: This prospective study was done in tramadol overdose patients without uncontrolled epilepsy and head injury history. All cases admitted in Loghman and Rasol Akram Hospitals, Tehran, Iran from 1, April 2011 to 1, April 2012 were included and observed for at least 12 hours. Time interval between tramadol intake and first seizure were record. Then, patients with second drug-induced seizure were recognized and log time between the first and second seizure was analyzed. The patients were transferred to the intensive care unit (ICU) if clinical worsening status observed. One week after hospital discharge, telephone follow-up was conducted. Results: A total of 150 patients with a history of tramadol induced seizures (141 men, 9 women, age: 23.23Â±5.94 years) were enrolled in this study. Convulsion was seen in 104 patients (69.3). In 8 out of 104 patients (7.6) two or more convulsion was seen. Time interval between tramadol use and the onset of the first and second seizure were 0. 93Â±0.17 and 2. 5Â±0.75 hours, respectively. Tramadol induced seizures are more likely to occur in males and patients with a history of drug abuse. Finally, one hundred forty nine patients (99.3) were discharged with good condition and the only one patient died from tramadol overdose. Conclusion: The results of the study showed tramadol induced seizure most frequently occurred within the first 4 hours of tramadol intake. The chance of experiencing a second seizure exists in the susceptible population. Thus, 4 hours after drug intake is the best time for patients to be hospital discharged.

Preliminary design and experimental studies of a novel soft implant for correcting sagittal plane instability in the lumbar spine.

STUDY DESIGN A novel soft implant design for resisting the instability of the lumbar spine in the sagittal plane was mechanically tested. OBJECTIVES To ascertain whether a soft preformed implant made of differing grades of silicone would contribute to stabilizing the lumbar spine in the sagittal plane. SUMMARY OF BACKGROUND DATA Methods of stabilizing the lumbar spine in patients who present with chronic low back pain have usually concentrated on rigidly fixing the associated segment. This has many inherent problems with both the surgical methods and the long-term rigidity at and away from the stabilized site. To the authors knowledge, no "soft" interspinous spacer that would allow a certain amount of flexion but still stabilize the movements associated with instability at the level of the lesion has been investigated mechanically as an alternative to rigid fixation or prosthetic replacement. METHODS The apparatus was designed to allow a cadaveric lumbar motion segment to be tested in compression at four angles of flexion with loads up to 700 N. The intradiscal pressure and sagittal plane stiffness were recorded during loading, with and without various sizes of the soft silicone implants placed between the spinous processes. RESULTS Insertion of the silicone implants between the spinous processes reduced the intradiscal pressure under load at the angles of flexion tested. The size of the interspinous space determines the optimal diameter of the implant that afforded sagittal stability, the load-bearing contribution of the implant, and the prevention of disc space narrowing at the level investigated. CONCLUSIONS A circular silicone spacer placed between the spinous processes appears to contribute to the stability of the cadaveric lumbar spine. There are many attractions to using a simple, soft implant that can be placed with minimal surgery between the spinous processes.
Designerly ways of knowing

Abstract This is the third paper in a series being published in Design Studies, which aims to establish the theoretical bases for treating design as a coherent discipline of study. The first contribution in the series was from Bruce Archer, in the very first issue of Design Studies, and the second was from Gerald Nadler, in Vol 1, No 5. Further contributions are invited. Here, Higel Cross takes up the arguments for a ‘third area’ of education—design—that were outlined by Archer. He further defines this area by contrasting it with the other two—sciences and humanities—and goes on to consider the criteria which design must satisfy to be acceptable as a part of general education. Such an acceptance must imply a reorientation from the instrumental aims of conventional design education, towards intrinsic values. These values derive from the ‘designerly ways of knowing’. Because of a common concern with these fundamental ‘ways of knowing’, both design research and design education are contributing to the development of design as a discipline.
