Effect of smoking on health service utilization.
보건학과/박사[한글]
흡연이 질병발생의 위험을 높인다는 지금까지의 역학적인 연구에도 불구하고 과연 흡연이 의료이용을 증가시키는가 하는 점에 대해서는 학자들간의 논란이 많다. 이 연구는 흡연이 질병이환과 의료이용을 증가시키는지를 알아보고자 하였다.연구자료는 1989년 국민건강조사 자료이며 그중 흡연조사가 실시되었던 5,20명을 연구표본으로 하여 흡연력에 따라 질병이환과 의료이용을 비교하였다. 주요결과는 다음과 같다.
첫째, 다변수로지스틱 모형에 의하면 다른 조건이 일정할 때 급성질환의 유병률은 비흡연자에 비해 남자 과거흡연자는 1.9배 여자 흡연자는 1.7배로 유의하게(p<0.05) 높았다.남자 흡연자의 흡연시작연령이 18세 이하인 경우 비흡연자에 비해 급성질환 유병률이 2.4배로 유의하게(p<0.05)높았다.
만성질환의 유병률은 비흡연자에 비해 남자 과거흡연자가 1.4배로 높았으나 유의하지는 않아다.
둘째, 과거흡연자는 비흡연자에 비해 입원이용과 외래이용을 더 많이 하였다. 입원이용은 여자인 경우 현재흡연자에게 비흡연자에 비해 2.5배 많았고, 외래이용은 남자인 경우과거흡연자에서 2.1배, 흡연시작연령이 18세 이하에서 2.3배, 그리고 여자인 경우 현재흡
연자에게 1.5배 많았다. 또한 과거흡연자가 건강에 관한 관심이 있는 경우 그렇지 않은 경우에 비해 외래이용을 3.4배 더 많이 하였으며 이들은 모두 통계학적으로 유의하였다.
셋째, 가중희귀분석 모형에 의하면 다른 조건이 일정할 때 남자 외래 치료일수가 현재 흡연자와 과거흡연자에서 비흡연자보다 유의하게 길었다. 그러나 여자의 경우는 흡연여부 별 치료일수가 유의한 차이가 없었다.
이 연구는 흡연은 급성 및 만성질환의 이환은 물론 입원 및 외래이용의 증가에 영향을 준다는 결론을 유도하였다.
향후 이 연구와 관련하여 오랜기간 추적된 표본을 가지고 질병별로 이환과 의료이용에 관한 심층분석으로 흡연이 국민건강에 미치는 영향을 좀더 분명하게 밝힐 필요가 있다고 생각한다.

It is well known that smoking increases the prevalence of diseases. During recent years, studies on the effect of smoking on health service utilization have brought about wide dispute among researchers.
This study involved direct observation of the differences in prevalence of disease and utilization of medical care by smokers, non-smokers, and ex-smokers. The data which were collected for the 1989 Korean National Health Survey(1989 KNHS) were used. The KNHS selected random sample of 5,201 individuals aged 20 to 59
representative of the whole Korean population.
Research findings are as fellows :
1. The risk for prevalence of diseases was increased among ex-smokers. The diseases showing increased positive risks included acute disease(relative risk, RR=1.9 for ex-smokers vs non-smokers) among male. and acute disease(RR=1.7 for current smokers) among female.
2. Smokers admitted to hospital during the years preceding the interview more than non-smokers, and also ex-smokers used more outpatient services and inpatient services than non-smokers. Health services showed significantly elevated positive risks related to smoking behavior were admission(RR=2.5 for current smokers) among female, outpatient visits(RR=2.1 for ex-smokers, RR=2.3 for age started smokings was less than 18 years) among male and (RR=1.5 for current smokers) among female.
The interaction term between the ex-smokers and the self-concern on health status was statistically significant in multiple regression model which explained the rate for outpatient visits(RR=3.4 for ex-smoker) among male.
3. The days of medication were statistically significantly increased in current smokers and ex-smokers in the weighted least square regression model among mate.
These effects persisted after controlling for major identified potential confounding factors.
Thus, the results of this study confirm that smoking is an important cause of prevalence of diseases and a major contributory factor to the use of health services.

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
The Korean prediction model for adolescents' future smoking intentions.
OBJECTIVES: The purpose of this study was to develop a prediction model for future smoking intention among Korean adolescents aged 13 to 15 in order to identify the high risk group exposed to future smoking. METHODS: The data was collected from a total of 5940 students who participated in a self-administrated questionnaire of a cross-sectional school-based survey, the 2004 Korea Global Youth Tobacco Survey. Chi-square tests and logistic regression analyses were carried out to identify the relevant determinants associated with intentions of adolescents' future smoking. Receiver Operation Characteristic (ROC) assessment was applied to evaluate the explanation level of the developed prediction model. RESULTS: 8.4% of male and 7.2% of female participants show their intentions of future smoking. Among non-smoking adolescents; who have past smoking experience [odds ratio (OR) 2.73; 95% confidence interval (CI) 1.92 - 3.88]; who have intentions of smoking when close friends offer a cigarette (OR 31.47; 95% CI = 21.50 - 46.05); and who have friends that are mostly smokers (OR 5.27; 95% CI = 2.85 - 9.74) are more likely to be smokers in the future. The prediction model developed from this study consists of five determinants; past smoking experience; parents smoking status; friends smoking status; ownership of a product with a cigarette brand logo; and intentions of smoking from close friends' cigarette offer. The area under the ROC curve was 0.8744 (95% CI=0.85 - 0.90) for current non-smokers. CONCLUSIONS: For efficiency, school-based smoking prevention programs need to be designed to target the high risk group exposed to future smoking through the prediction model developed by the study, instead of implementing the programs for all the students
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
Cancer prevention in Asia: resource-stratified guidelines from the Asian Oncology Summit 2013
With economic growth in Asia, cancer has become increasingly prominent as a major health problem. However, discrepancies in infrastructure, economics, and development exist within and between Asian countries. We assess means of primary and secondary prevention for cervical, breast, colorectal, and hepatocellular cancer, and off er recommendations according to resource levels. Primary prevention by health education, lifestyle modification, and avoidance of risk factors should be made available at all resource levels. When resources allow, human papillomavirus and hepatitis B vaccinations should be given to reduce the risk of cervical and hepatocellular cancer, and genetic testing should be offered to detect increased susceptibility to colorectal and breast cancer. Secondary prevention by effective yet affordable screening for precancerous lesions or by early detection of cancer should be offered, followed by appropriate treatment
