Oral Health Status and Treatment Needs of Elderly in Phitsanulok
No full text Oral health is an important part of overall wellbeing of elderly in Thailand. Studies in many countries show that oral health status of elderly is poor and there is an urgent need to improve. Assessment of the oral health status and the needs of older people will aid in the organization of a prevention-oriented oral health care program to improve the quality of life of elderly. The purpose of this study was to describe the oral health status and dental treatment needs of an elderly population. The subjects were elderly people (60-92 years old), who live in Phitsanulok, Thailand. A total of 612 participants (158 males and 454 females, mean age 68.8±5.9) agreed to join the study. The oral examination was performed by one dentist to detect periodontal status The Community Periodontal Index: (CPI) and dental caries status ware reported as decayed, missing, or filled teeth (DMFT), followed those recommendation by the World Health Organization. In addition, prosthetic status and treatment needs were classified according to WHO criteria and also recorded. Information on self-perceived oral health problems, oral function and oral health behavior was obtained via questionnaires. The results showed that, thirty percent of subjects had no natural teeth. The mean DMFT score was 18.9±8.3 (DT=2.0±2.8, MT=16.3±8.3, FT=0.7±2.2) teeth per person. The mean number of DMFT and MT significantly increased with age, with MT dominating in the DMFT index (p<0.05). Thirty-five percent of subjects needed dental fillings and 20 % required tooth extractions. The percentage of elderly with shallow (4-6mm) and deep (>6 mm) periodontal pockets were 9.6 and 26.6 respectively. Half (49.9%) of all subject needed periodontal treatment. Forty-eight percent of subjects need both upper and lower jaw partial dentures, 8.5 % needed complete dentures. The top five of self-perceived oral problems of elderly were: dental caries; gum disease; halitosis; difficulty in chewing hard food and tooth sensitivity. The oral health status of elderly examined in this study was poor due to high levels of tooth loss, caries experience and prevalence of periodontal pockets. Dental care, especially prosthetic care, should be focused upon. Thus, oral health program that emphasizes prevention should be considered of particular important for elderly.

The Prevalence and Related Factors of Anterior Open Bite in Dental Patients of the Lower Northern Part of Thailand
No full text The aim of this study was to determine the prevalence of anterior open bite and interpret its related factors. A cross-sectional study was carried out in 400 dental patients (169 males, 231 females, ages from 4 years, mean age 31 + 21.9 years) who attended dental hospital, Naresuan university. The presence of anterior open bite and other factors was collected with clinical examination and history taking by one trained dentist. Ninety one patients (25.7%) presented anterior open bite. The patients aged 4-18 years presented the most prevalence compared with others. Logistic regression showed tongue-thrust swallowing and non-nutritive sucking were significantly related to anterior open bite with Odd ratio = 2.5 (1.302-5.933) and 3.5 (1.429-8.411) respectively. For relationship between anterior open bite and other types of malocclusion, we found spacing of maxillary incisors and large overjet were significantly related to anterior open bite with Odd ratio = 5.6 (2.093-14.929) and 1.6 (1.121-2.453) respectively. In conclusion, dental patients of the lower northern part of Thailand presented a high prevalence of anterior open bite which related to certain types of malocclusion and abnormal oral habits. Dentist should realize this high prevalence and emphasize the management of anterior open bite and its related factor which could be the main problem in dental treatment procedure.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
