  • 본 연구는 고등학생들이 지각하는 흡연자에 대한 이미지 척도를 개발하고 타당화하며, 흡연자에 대한 이미지가 청소년들의 성인기 흡연 의도에 미치는 영향을 검증하기 위해 수행되었다. 이를 위해 고등학생 610명을 대상으로 흡연자 이미지 척도를 개발하고 신뢰도와 타당도를 검증하였다. 또한 흡연자에 대한 긍정적인 이미지가 성인기 흡연 의도에 미치는 영향은 순서 로지스틱 회귀분석으로 검증하였다. 연구결과, 첫째, 흡연자 이미지 척도의 구성타당도 분석 결과 단일요인 10개 문항으로 나타났으며, 내적 일치도 계수는 .91로 높았다. 둘째, 담배광고로 인해 형성된 흡연자에 대한 긍정적인 이미지는 남자와 흡연자가 유의하게 높게 나타났다. 셋째, 흡연자에 대한 긍정적인 이미지는 성별과 흡연 여부를 통제한 상태에서 성인기 흡연의도에 유의한 정적 영향을 미쳤다. 이러한 연구결과를 바탕으로 담배광고로 인해 형성된 흡연자에 대한 긍정적인 이미지가 청소년들의 성인기 흡연 의도를 증가시키는 위험에 대한 시사점 및 후속연구에 대한 제언을 논의하였다.

  • Although researches have highlighted the important role of enhanced farm biosecurity to reduce the severity and prevalence of diseases in livestock, to date there has been little study in Korea on farmers' adoption of biosecurity measures to control porcine reproductive and respiratory syndrome virus (PRRSV) infection. To mitigate the risk of PRRSV infection in pigs, the risk factors by which PRRSV is introduced in pig farms must be determined. The primary aim of this study was to investigate pig producers' perceptions about on-farm biosecurity practices. We also analyzed data obtained from a cross-sectional study on 196 farrow-to-finish farms conducted between March 2013 and February 2014 to identify risk factors for PRRSV infection at farm level. Standardized questionnaires with information about basic demographical data and management practices were collected in each farm by on-site visit of trained veterinarians. Farms were classified as negative or positive through the use of infection profiles that combined data on PCR positive pigs and serological testing including antibody titer, sero-conversion pattern at each age category, and vaccination status. Data on biosecurity practices, farm management and environmental characteristics were analyzed using multivariate ordinal logistic regression. Generally, the biosecurity level in the pig farms included in this study were insufficient to reduce/prevent the risk of PRRSV infection given the high pig density areas and the considerable extent of vehicle movement. Factors associated with PRRSV infection were those where owners used on-farm vaccination programs had a lower risk of infection (OR = 0.19, 95% CI 0.06-0.61). The results from the analysis may guide to tailor biosecurity measures in the reduction or prevention of PRRS to the specific circumstances of pig farms in different localities of the world. To the best knowledge of the authors, this is the first study to report information on the biosecurity practices currently implemented on Korean pig farms.

  • This study was carried out to investigate what kinds of statistical techniques have been used to analyze data from oriental medicine research, For study, 551 original articles which used statistical techniques in their data analysis were selected form the articles published in The journal of Korean Acupuncture & Moxibustion Society(JKAMS) between 1984 to 2002. among them, 122 articles used descriptive statistics while 429 articles used inferential statistics for data analysis. For that 429 articles, t-test (189 articles), analysis fo variance (111 articles), chi-square test (14 articles), correlation (10 articles), regression analysis (4 articles), factor analysis(5 articles), or nonparametric test (23 articles) were chose to analyze the data. Nonparametric approach has substantial power in case data do not meet the assumption of normality. This method is not only easy to use ut also provides measures of the statistical variation of nominal and ordinal scale. This study shows that more and more recent papers use nonparametric test compared to the old articles. nine different statistical software or packages (SAS, SPSS, Statview, Minitab, Sigma plot, ISP, Graphpad prism, Excel, Access) have been used in the articles published JKMAS. High level statistical techniques such as SAS, SPSS, and Statview are user friendly and used most for acupuncture and Moxibustion research. Including tables and plots in an article facilitates understanding family process data from a descriptive standpoint, minimized erroneous statistical conclusions, and clarifies theoretically important relationships among variables. Table and plots have been used 500 and 233 articles, respectively. A computer procedure is proposed and illustrated with statistical packages using SAS, SPSS, Statview and ISP.

  • Purpose: Alcohol ingestion enhances impulsivity and aggression, and has been proven to have a close relationship with suicide. This study investigates whether alcohol co-ingestion affects the Poisoning Severity Score (PSS) grade in patients with intentional poisoning. Methods: We conducted a retrospective analysis of intentional poisoning patients who visited the emergency department (ED) from January 1 to December 31, 2020. Patients were divided into non-drunken and drunken groups. We collected the data based on the medical records of the patients and serum ethanol level results recorded during initial blood tests at the ED. To grade the PSS, the highest score was assessed through clinical signs and test results during the hospital stay. A comparative analysis was conducted between the two groups. Results: A total of 277 patients were included in the study. 163 (58.8%) were in the non-drunken group, and 114 (41.2%) were in the drunken group. The PSS grade showed a significant difference between the two groups (p=0.002). While grade 1 (mild) was observed more in the non-drunken group, grade 2 (moderate) and grade 3 (severe) were seen more in the drunken group. In an ordinal logistic regression analysis, alcohol co-ingestion (adjusted odds ratio [aOR] 2.557, 95% confidence interval [CI] 1.554-4.208, p<0.001) was considered to be a risk factor for a higher PSS grade. There was no significant correlation between the serum ethanol level and the PSS grade. (p=0.568) Conclusion: Intentional poisoning patients with alcohol co-ingestion had a higher PSS. Hence close observation and aggressive treatment in the ED is warranted in such cases.

  • 본 연구는 금연 시도와 인지된 스트레스 정도와의 연관성을 규명하고 금연을 시도함에 있어 인지된 스트레스에 영향을 미치는 요인을 확인하고자 한다. 본 연구에서는 2015 국민건강영양조사 대상자 중 만 19세 이상인 참여자를 대상으로 하였으며, 금연시도 및 성공 여부와 인지된 스트레스 정도의 연관성을 파악하기 위해 순서형 로지스틱 회귀분석을 수행하였다. 금연 시도에 실패한 흡연자가 금연시도에 성공한 흡연자보다 더 높은 스트레스와 연관성이 있는 것으로 나타났으며(OR=1.72, 95% CI: 1.41-2.08) 금연시도를 하지 않은 흡연자(OR=1.05, 95% CI: 0.71-1.55)에 대해서는 유의한 차이가 없었다. 본 연구는 금연 실패와 흡연자들의 높은 스트레스 정도 간의 연관성을 확인하였으며, 흡연자가 완전한 금연 성공에 도달하지 못하는 원인 중 하나로 금연 실패 후 겪는 높은 스트레스를 제시한다. 또한 흡연자들의 금연 시도를 증진하기 위하여 금연 실패 후 겪는 스트레스와 같은 정신과학적 장벽을 낮추기 위한 정책적 접근이 요구된다.

  • The primary aim of this study was to investigate biosecurity practices in pig farms and to determine the major risk factors associated with PCV2 infection for a sampled swine population in Korea. To this end, we analyzed data from a cross-sectional study of 296 farrow-to-finish farms, which was conducted between March and September 2014 to explore the prevalence of swine disease at farm level. Face-to-face interviews by on-site visit of trained veterinarians were conducted with the farm owners or managers using a standardized questionnaires with information about basic demographical data and management practices. Farms were classified as negative or positive through the use of infection profiles that combined data on serological testing including PCR antigen test result, antibody titer and sero-conversion pattern at each age category taking into account vaccination status. Data were analyzed using multivariate ordinal logistic regression. Results from this study indicated that biosecurity level of the farms was considered not good given low compliance of the biosecurity programs and facilities in the farm: off-site removal of dead stocks (7%), off-site location of storage facility for incoming feeds (12.6%), off-site pick-up location for finishers (19.3%), restrictions on feed supplier vehicles for farm entrance (19.6%), restriction of finisher trucks entering the farm (22.4%), and restriction on manure disposal trucks entering the farm (26.4%). In the final model (n = 255), allowance of finisher truck driver to the pig unit had increased risk of infection (OR = 2.4, 95% CI 1.22-4.67) whereas farms with a sign forbidding the entrance had decreased risk of infection (OR = 0.19, 95% CI 0.10-0.58). Further comprehensive research with larger sample size is required to better understand the multifactorial characteristic that some predisposing risk factors that were not available in this study. To the best knowledge of the authors, this was the first study to use empirical data to report risk factors associated with PCV2 infection in the Korean pig farms. Results from the current study could be used to decide optimal biosecurity measures to reduce the impact of PCV2 infection to farmers and policy makers.
