A Differential Equation Model for the Dynamics of Youth Gambling
Tae Sug Do, Young S. Lee
Osong Public Health Res Perspect. 2014;5(4):233-241.   Published online August 31, 2014
Objectives We examine the dynamics of gambling among young people aged 16–24 years, how prevalence rates of at-risk gambling and problem gambling change as adolescents enter young adulthood, and prevention and control strategies. Methods A simple epidemiological model is created using ordinary nonlinear differential equations, and a threshold condition that spreads gambling is identified through stability analysis. We estimate all the model parameters...
Molecular Typing of Mycobacterium intracellulare Using Pulsed-Field Gel Electrophoresis, Variable-Number Tandem-Repeat Analysis, Mycobacteria Interspersed Repetitive-Unit-Variable-Number Tandem Repeat Typing, and Multilocus Sequence Typing: Molecular Characterization and Comparison of Each Typing Methods
Semi Jeon, Nara Lim, Seungjik Kwon, Taesun Shim, Misun Park, Bum-Joon Kim, Seonghan Kim
Osong Public Health Res Perspect. 2014;5(3):119-130.   Published online June 30, 2014
Objectives Mycobacterium intracellulare is the major causative agent of nontuberculous mycobacteria-related pulmonary infections. The strain typing of M. intracellulare is important for the treatment and control of its infections. We compared the discrimination capacity and effective value of four different molecular typing methods. Methods Antibiotic susceptibility testing, hsp65 and rpoB sequencing, pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), mycobacteria interspersed repetitive-unit-variable-number tandem-repeat...
Exposure to Dichlorodiphenyltrichloroethane and the Risk of Breast Cancer: A Systematic Review and Meta-analysis
Jae-Hong Park, Eun Shil Cha, Yousun Ko, Myung-Sil Hwang, Jin-Hwan Hong, Won Jin Lee
Osong Public Health Res Perspect. 2014;5(2):77-84.   Published online April 30, 2014
Objectives This study extended and updated a meta-analysis of the association between exposure to dichlorodiphenyltrichloroethane (DDT) and the risk of breast cancer. Methods We reviewed the published literature on exposure to DDE and breast cancer risk to update a meta-analysis from 2004. The total of 35 studies included 16 hospital-based case–control studies, 11 population-based case–control studies, and 10 nested case–control studies identified through...
Forecasting the Number of Human Immunodeficiency Virus Infections in the Korean Population Using the Autoregressive Integrated Moving Average Model
Hye-Kyung Yu, Na-Young Kim, Sung Soon Kim, Chaeshin Chu, Mee-Kyung Kee
Osong Public Health Res Perspect. 2013;4(6):358-362.   Published online December 31, 2013
Objectives From the introduction of HIV into the Republic of Korea in 1985 through 2012, 9,410 HIV-infected Koreans have been identified. Since 2000, there has been a sharp increase in newly diagnosed HIV-infected Koreans. It is necessary to estimate the changes in HIV infection to plan budgets and to modify HIV/AIDS prevention policy. We constructed autoregressive integrated moving average (ARIMA) models...
Proteomic Analysis of Intracellular and Membrane Proteins From Voriconazole-Resistant Candida glabrata
Jae Il Yoo, Hwa Su Kim, Chi Won Choi, Jung Sik Yoo, Jae Yon Yu, Yeong Seon Lee
Osong Public Health Res Perspect. 2013;4(6):293-300.   Published online December 31, 2013
Objectives The proteomic analysis of voriconazole resistant Candida glabrata strain has not yet been investigated. In this study, differentially expressed proteins of intracellular and membrane fraction from voriconazole-susceptible, susceptible dose-dependent (S-DD), resistant C. glabrata strains were compared with each other and several proteins were identified. Methods The proteins of intracellular and membrane were isolated by disrupting cells with glass bead and centrifugation from...
Evaluation and Selection of Multilocus Variable-Number Tandem-Repeat Analysis Primers for Genotyping Brucella abortus Biovar 1 Isolated from Human Patients
Subok Lee, Kyu-Jam Hwang, Mi-Yeoun Park, Seon-Do Hwang, Hee-Youl Chai, Hyuk Chu, Sang-Hee Park
Osong Public Health Res Perspect. 2013;4(5):265-270.   Published online October 31, 2013
Objectives Brucellosis is the most common bacterial zoonosis in the world. Multilocus variable-number tandem-repeat (VNTR) analysis (MLVA) is a molecular method for genotyping bacterial species. Brucella abortus biovar I was isolated from most of the brucellosis-suspected patients in Korea. This study was conducted to investigate the ability of various MLVA primers that are used for molecular typing B. abortus isolates and...
Spatial Distribution Analysis of Scrub Typhus in Korea
Hong Sung Jin, Chaeshin Chu, Dong Yeob Han
Osong Public Health Res Perspect. 2013;4(1):4-15.   Published online February 28, 2013
Objective: This study analyzes the spatial distribution of scrub typhus in Korea. Methods: A spatial distribution of Orientia tsutsugamushi occurrence using a geographic information system (GIS) is presented, and analyzed by means of spatial clustering and correlations. Results: The provinces of Gangwon-do and Gyeongsangbuk-do show a low incidence throughout the year. Some districts have almost identical environmental conditions of scrub typhus incidence. The land use...

Phylogenetic Analysis of the Rotavirus Genotypes Originated from Children < 5 Years of Age in 16 Cities in South Korea, between 2000 and 2004
Ho-Kyung Oh, Seung-Hwa Hong, Byung-Yoon Ahn, Hye-Kyoung Min
Osong Public Health Res Perspect. 2012;3(1):36-42.   Published online December 31, 2011
Objectives The purpose of this study was to examine the diversity of the G and P types of human rotavirus strains isolated in South Korea during 2000 to 2004. Methods We selected 38 Group A rotavirus isolates among 652 fecal samples, which were collected from infants and children < 5 years of age with acute gastroenteritis or diarrhea admitted in 8 hospitals representative...
Sensitivity Analysis of the Parameters of Korea’s Pandemic Influenza Preparedness Plan
Chaeshin Chu, Junehawk Lee, Dong Hoon Choi, Seung-Ki Youn, Jong-Koo Lee
Osong Public Health Res Perspect. 2011;2(3):210-215.   Published online December 31, 2011
Objectives Our aim was to evaluate Korea’s Pandemic Influenza Preparedness Plan. Methods We conducted a sensitivity analysis on the expected number of outpatients and hospital bed occupancy, with 1,000,000 parameter combinations, in a situation of pandemic influenza, using the mathematical simulation program InfluSim. Results Given the available resources in Korea, antiviral treatment and social distancing must be combined to reduce the number of outpatients and...
