Incidence of vaginal breech delivery in singleton in Siriraj Hospital.

OBJECTIVE To determine the incidence of vaginal breech delivery at Siriraj Hospital and to evaluate factor affecting mode of delivery. DESIGN Cross-sectional study. SETTING Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University. SUBJECT A total of 317 women with singleton breech presentation, > or =28 weeks of gestation, who had their deliveries at Siriraj Hospital during January 1st to December 31st 2003. MATERIAL AND METHOD The medical records of these women were reviewed to determine the incidence of vaginal breech delivery. Characteristics regarding current pregnancy and delivery and maternal and fetal outcomes were evaluated, including parity, gestational age, estimate fetal weight, cervical dilation, membranes status, maternal complications, types of breech presentation, and being a private case. RESULTS The incidence of vaginal breech delivery among these women was 17.7%. Univariate analysis showed that multiparity, gestational age of <32 weeks, estimate fetal weight of < or =2500 grams, advanced cervical dilatation, ruptured membranes, and not being a private case increased the risk of vaginal breech delivery. Multiple logistic regression analysis demonstrated that only advanced cervical dilatation (4-7 cm, adjusted OR 10.7, 95% CI 3.5-33.0; >7 cm adjusted OR 40.4, 95% CI 12.6-129.2), ruptured membranes (adjusted OR 2.9, 95% CI 1.3-6.3), multiparity (adjusted OR 6.4, 95% CI 2.6-15.7), and gestational age <32 weeks (adjusted OR 9.7, 95% CI 2.7-35.7) were independently associated with vaginal breech delivery. However, lower apgar scores and neonatal complications, especially prematurity, were more frequent in vaginal than cesarean delivery. CONCLUSION Vaginal breech delivery was found in 17.7% of singleton breech presentation in Siriraj Hospital. Certain characteristics during labor and delivery were associated with mode of delivery including advanced cervical dilatation, ruptured membranes, multiparity, and preterm gestational age.
Performance Bounds for MIMO-OFDM Channel Estimation

The performance of a mobile multiple-input multiple-output orthogonal-frequency-division multiplexing (MIMO-OFDM) system depends on the ability of the system to accurately account for the effects of the frequency-selective time-varying channel at every symbol time and at every frequency subcarrier. Typically, pilot symbols are strategically placed at various times over various subcarriers in order to calculate sample channel estimates, and then these estimates are interpolated or extrapolated forward to provide channel estimates where no pilot data was transmitted. Performance is highly dependent on the distribution of the pilots with respect to the coherence time and coherence bandwidth of the channel, and on the chosen channel parameterization. In this paper, a vector formulation of the Cramer-Rao bound (CRB) for biased estimators and for functions of parameters is used to derive a lower bound on the channel estimation and prediction error of such a system. Numerical calculations using the bound demonstrate the benefits of multiple antennas for channel estimation and prediction and illustrate the impact of modeling errors on estimation performance when using channel models based on calibrated arrays.
Tumor Targeting Potential and Metabolism of 5‐[125I]Iodo‐2′‐Deoxyuridine Injected Intratumorally in Patients with Breast Cancer a

We have previously demonstrated the high tumor targeting potential of the thymidine analogue 125IUdR in experimental animal models following direct intratumoral or locoregional (intracavitary) administration. The aim of the present work was to evaluate the metabolism and selectivity (based on differential cell proliferation kinetics) of 125IUdR incorporation in patients with breast cancer following a similar approach. 125IUdR (4-8 MBq) was injected intratumorally by ultrasound-guided percutaneous injection in 7 patients with breast cancer 24 hours before ablative surgery. Blood and urine samples were collected up to 72 hours after injection and analyzed by HPLC using a C18 reversed-phase column and methanol:water (20:80) as the mobile phase. Following resection, the radioactivity of the tumor and the surrounding tissues was measured in a gamma counter, and microautoradiography was performed on semithin tissue sections to determine the site of tracer incorporation at the cellular level. Activity in plasma peaked at 0.5 to 1 hour after 125IUdR injection (4.96 +/- 1.08% of injected dose/liter), declining thereafter with a mean T1/2 of 11.24 +/- 2.78 hours. By HPLC analysis, undegraded 125IUdR was about 15-30% of total plasma activity, with a biphasic pattern peaking at both 1-3 hours and approximately 12 hours. In addition to free 125I-, about 10% of early plasma activity was constituted by a labeled metabolite (tentatively identified as radio-iodouracil), rising to about 50-60% at later time points. About 70-90% of urinary radioactivity was 125I-, and 5-20% was undegraded 125IUdR in the first 24-hour samples, while the remainder was iodouracil. High tumor/nontumor ratios were obtained (mean 147.4 +/- 125.2, range 27-397) with average tumor/blood ratios at the time of surgery equal to 32.7 +/- 18.6 (range 5-56). An average 0.0244 +/- 0.0189% of the injected dose was present per gram of tumor (range 0.001-0.061% ID/g). Microautoradiography confirmed the high values of tumor/nontumor incorporation ratios and demonstrated the specificity of 125IUdR incorporation mostly in the tumor cell nuclei, with only occasional incorporation by normal-appearing tubular cells. These results suggest the potential of radiolabeled IUdR for tumor targeting in humans, to be used whenever a satisfactory route of locoregional administration allowing for homogeneous tracer distribution within the tumor mass is accessible and in the presence of favorable tumor cell proliferations kinetics.
Normalized tree partitioning for image segmentation

In this paper, we propose a novel graph based clustering approach with satisfactory clustering performance and low computational cost. It consists of two main steps: tree fitting and partitioning. We first introduce a probabilistic method to fit a tree to a data graph under the sense of minimum entropy. Then, we propose a novel tree partitioning method under a normalized cut criterion, called normalized tree partitioning (NTP), in which a fast combinatorial algorithm is designed for exact bipartitioning. Moreover, we extend it to k-way tree partitioning by proposing an efficient best-first recursive bipartitioning scheme. Compared with spectral clustering, NTP produces the exact global optimal bipartition, introduces fewer approximations for k-way partitioning and can intrinsically produce superior performance. Compared with bottom-up aggregation methods, NTP adopts a global criterion and hence performs better. Last, experimental results on image segmentation demonstrate that our approach is more powerful compared with existing graph-based approaches.
Religious Priming Increases Help if Requesters Dress Poorly: Effects of Dress, Priming, and Task Difficulty on Helping Behaviors

The present study investigated requester–helper interaction, helper personal disposition, and their interactions in effecting helping behavior. In a 2 × 2 × 2 experimental design, participants were asked to help with an effortful or effortless task by a well-dressed or poorly dressed help requester after being primed with religious or neutral words. Results showed that well-dressed requesters, religious primes, and effortless tasks independently increased helping behavior, and helping with effortful task requested by poorly dressed requesters particularly increased after religious primes. These findings provide an integrated understanding of the micro and meso causes of helping behavior.
Security, protection, and family norms: Gendered and selective regulations of marriage and migration in Italy and Portugal

This paper engages in a critical reflection on specific normative policies concerning migration and family in two contemporary European contexts. The analysis is based on fieldwork carried out in Portugal and Italy1, exploring the discourses and practices concerning the marriage of undocumented migrants in the context of the construction of “marriage of convenience” control policies. The underlying hypothesis is that the policing of mobility and intimate lives reproduces inequalities by intervening on the opportunities and constraints faced by some categories of migrants. Grounded in the literature exploring these mechanisms as part of broader processes of migrant inclusion and exclusion in the context of global human mobilities, the analysis problematizes both the criminalizing and victimizing perspectives on “undocumented migration”. On one side, the paper will discuss the problematic -and gendered- assumptions underpinning restrictive migratory policies. These include the invocation of “security” purposes, the protection of “vulnerable” groups, and the safeguard of national “family norms” in order to corroborate the restriction of migrant‟s rights. On the other side, the paper will give a brief overview of current laws, policies and institutional practices in the case studies, stemming from the preliminary qualitative analysis of empirical materials collected for the broader PhD project. These data indicate that rather than reaching their alleged goals, such restrictive migration control apparatuses potentially produce and reproduce the stratification of subjects along gender, socioeconomic and national origin lines.
Organizational diagnostic factors in family business

Purpose – To examine organizational diagnostics taken from the best practice model of change as organizational diagnostic factors in a specific type of business such as family businesses. These account for many of companies in Asia and are regarded as a special from the mixture of management focus on business, family and ownership.Design/methodology/approach – In order to manage changes in family business successfully, the organizational diagnostic factors are analyzed from executives' in‐depth interviews with Thai family businesses that implement new IT systems.Findings – Communication, generation, ownership, family structure, politics and national culture are six diagnostic factors in Thai family businesses that are not the same as the model of change.Originality/value – Consultants and change agents in family businesses, especially in Asia, can use these factors as an additional guideline for their effective change management.
Mac‐2 binding protein is a cell‐adhesive protein of the extracellular matrix which self‐assembles into ring‐like structures and binds β1 integrins, collagens and fibronectin

Human Mac‐2 binding protein (M2BP) was prepared in recombinant form from the culture medium of 293 kidney cells and consisted of a 92 kDa subunit. The protein was obtained in a native state as indicated by CD spectroscopy, demonstrating α‐helical and β‐type structure, and by protease resistance and immunological analysis. It was highly modified by N‐ and O‐glycosylation but not by glycosaminoglycans. Ultracentrifugation showed non‐covalent association into oligomers with molar masses of 1000–1500 kDa. Electron microscopy showed ring‐like shapes with diameters of 30–40 nm. M2BP bound in solid‐phase assays to collagens IV, V and VI, fibronectin and nidogen, but not to fibrillar collagens I and III or other basement membrane proteins. The protein also mediated adhesion of cell lines at comparable strength with laminin. Adhesion to M2BP was inhibited by antibodies to integrin β1 subunits but not to α2 and α6 subunits, RGD peptide or lactose. This distinguishes cell adhesion of M2BP from that of laminin and excludes involvement of lactose‐binding galectin‐3. Immunological assays demonstrated variable secretion by cultured human cells of M2BP, which was detected in the extracellular matrix of several mouse tissues.
Beginning To Read: Thinking and Learning about Print.

"Beginning to Read reconciles the debate that has divided theorists for decades over what is the "right" way to help children learn to read. Drawing on a rich array of research on the nature and development of reading proficiency, Marilyn Adams shows educators that they need not remain trapped in the phonics versus teaching-formeaning dilemma and offers instructional alternatives. She proposes that phonies can work together with the "whole language" approach to teaching reading and provides an integrated treatment of the knowledge and processes involved in skillful reading, the issues surrounding their acquisition, and the implications for reading instruction Broad in scope and clearly written, "Beginning to Read provides fresh insights into the relationship between thinking and learning. Developing the new connectionist theory as it relates to reading and its acquisition, Adams underscores the automatic nature of print perception in skillful readers while contrasting it with the attentive thought required for conceptual learning and understanding Adams reviews the history of debate over approaches to reading instruction as well as the research on their effectiveness, She consistently integrates instructional concerns with meticulous attention to research and theory from education, developmental and cognitive psychology, and linguistics. Throughout, she emphasizes the interdependence of meaning appreciation and orthographic facility in both fluent reading and its acquisition. Relevant learning theory is presented along with discussion of the roles of experience, practice, direct instruction, rules, thinking and understanding. Adams stresses the importance of preschool language andliteracy experiences and includes descriptions of those that will best prepare children for reading instruction. Marilyn Jager Adams is a Senior Scientist at Bolt Beranek and Newman Inc. She was Principal Author and Curriculum Coordinator/Editor for the five volume classroom instruction series, "Odyssey: A Curriculum for Thinking. Beginning to Read was developed in conjunction with the Reading Research and Education Center at the University of Illinois at Urbana-Champaign. Learning, Development, and Conceptual Change series.
Gender differences in consumers' acceptance of genetically modified foods

Research has shown that women are less accepting of genetically engineered products than men. We expect two mechanisms to be at work here. First, in consumer behaviour theory, more knowledge is assumed to lead to more acceptance. We assumed that for genetically engineered foods, this general principle does not apply since long-term consequences are not known yet. The well-informed consumer is likely to be comparatively more concerned with this lack of knowledge. We call this the information paradox. Theory on the topic is relatively recent. The results of this study will help to distinguish consumer behaviour with regard to new types of food as compared with traditional foods. Second, we assumed that there is a gender factor included in attitudes toward foods. In general, women still plan food and household purchases. A tentative attitude and an accompanying reluctance toward food innovation are adopted when buying food for children. We call this the gender paradox. In this exploratory study we use data from the Eurobarometer. Eurobarometer surveys have been executed since 1973 by the European Commission among the adult population of European Union member countries (n > 10 000), monitoring the evolution of public opinion. Analysis of these surveys shows that gender differences exist in the acceptance of genetically modified (GM) foods in Europe. Women tend to be less accepting toward genetically modified foods. This supports our gender hypothesis. However, no evidence was found to support the assumed information paradox. It seems that knowledge leads to acceptance, also of GM foods, but more so for men than for women
Exploration and classification of intensive care nurses' clinical decisions: a Greek perspective.

AIM The recording, identification, coding and classification of clinical decisions by intensive care nurses. BACKGROUND Clinical decision-making is an essential dimension of nursing practice as through this process nurses make choices to meet the goals of patient care. Intensive care nurses' decision-making has received attention because of the complexity and urgency associated with it, however, the types of nurses' clinical decisions have not been described systematically. METHODS Qualitative content analysis of daily diaries of clinical decisions recorded during nursing work by 23 purposefully selected intensive care nurses from three major hospitals of Greece. The process of data collection and analysis continued until the point of theoretical saturation. FINDINGS Eight categories of nursing clinical decisions emerged including decisions related to: (1) evaluation, (2) diagnosis, (3) prevention, (4) intervention, (5) communication with patients, (6) clinical information seeking, (7) setting of clinical priorities and (8) communication with health care professionals. Psychological assessment and support decisions were scarce, whereas patient input in care decisions appeared to be limited. The most frequent types of decisions were regarding intervention (29%), evaluation (25%) and clinical setting of priorities (17%), while clinical information seeking (3%) and communication with patients decisions (2%) were the least frequent. Additionally, recorded decisions were ranked in order of degree of urgency and of dependency on medical order. Non-urgent decisions were 78% of the total and 60% of nurses' intervention decisions were independent of medical order and were related to basic nursing care. CONCLUSIONS Intensive care nurses make multiple decisions that seem to be in line with the nursing process, although the latter is not officially implemented in Greek ICUs. RELEVANCE TO CLINICAL PRACTICE The types and frequency of clinical decisions made by intensive care nurses are related to features of ICU work environment, their professional autonomy and accountability, as well as their perceptions of their clinical role.

Dynamic quality-of-service for mobile ad hoc networks

This paper presents an approach to supporting quality-of-service (QoS) in a dynamic network environment. With this approach, resource reservations represent ranges, and applications adapt to an allocated level of QoS provided by the network at some point within the requested range. To explore this approach, we have implemented a new protocol called dynamic RSVP (dRSVP), which is an extension to RSVP.
Research Paper: Use of General-purpose Negation Detection to Augment Concept Indexing of Medical Documents: A Quantitative Study Using the UMLS

OBJECTIVES To test the hypothesis that most instances of negated concepts in dictated medical documents can be detected by a strategy that relies on tools developed for the parsing of formal (computer) languages-specifically, a lexical scanner ("lexer") that uses regular expressions to generate a finite state machine, and a parser that relies on a restricted subset of context-free grammars, known as LALR(1) grammars. METHODS A diverse training set of 40 medical documents from a variety of specialties was manually inspected and used to develop a program (Negfinder) that contained rules to recognize a large set of negated patterns occurring in the text. Negfinder's lexer and parser were developed using tools normally used to generate programming language compilers. The input to Negfinder consisted of medical narrative that was preprocessed to recognize UMLS concepts: the text of a recognized concept had been replaced with a coded representation that included its UMLS concept ID. The program generated an index with one entry per instance of a concept in the document, where the presence or absence of negation of that concept was recorded. This information was used to mark up the text of each document by color-coding it to make it easier to inspect. The parser was then evaluated in two ways: 1) a test set of 60 documents (30 discharge summaries, 30 surgical notes) marked-up by Negfinder was inspected visually to quantify false-positive and false-negative results; and 2) a different test set of 10 documents was independently examined for negatives by a human observer and by Negfinder, and the results were compared. RESULTS In the first evaluation using marked-up documents, 8,358 instances of UMLS concepts were detected in the 60 documents, of which 544 were negations detected by the program and verified by human observation (true-positive results, or TPs). Thirteen instances were wrongly flagged as negated (false-positive results, or FPs), and the program missed 27 instances of negation (false-negative results, or FNs), yielding a sensitivity of 95.3 percent and a specificity of 97.7 percent. In the second evaluation using independent negation detection, 1,869 concepts were detected in 10 documents, with 135 TPs, 12 FPs, and 6 FNs, yielding a sensitivity of 95.7 percent and a specificity of 91.8 percent. One of the words "no," "denies/denied," "not," or "without" was present in 92.5 percent of all negations. CONCLUSIONS Negation of most concepts in medical narrative can be reliably detected by a simple strategy. The reliability of detection depends on several factors, the most important being the accuracy of concept matching.
Impact strength of denture base and reline acrylic resins: An in vitro study

This study evaluated the impact strength of a denture base resin (Lucitone 550—L) and four reline resins (Tokuyama Rebase II—T; Ufi Gel Hard—U; New Truliner—NT, and Kooliner—K), both intact and in a reline combination (L/L, L/T, L/U, L/NT, and L/K). For each group (n = 20), half of the specimens were thermocycled before testing. Charpy tests were performed, and the impact strengths were calculated. Data were analyzed by two-way analyses of variance and Tukey’s test (p = 0.05). For the intact groups, mean impact strength values for L (1.65 and 1.50) were significantly higher than those of the reline resins (0.38–1.17). For the relined groups, the highest mean impact strength values were produced by L/T (5.76 and 5.12), L/NT (6.20 and 6.03), and L/K (5.60 and 5.31) and the lowest by L/U (0.76 and 0.78). There were no significant differences between L and L/L. Thermocycling reduced the impact strength of T (from 0.73 to 0.38) and L/L (from 1.82 to 1.56).
