  • The occurrence of wild boars (Sus scrofa Linnaeus) and reports of wildlife-vehicle conflicts (i.e., road-kill) involving them have increased in natural forest regions of Korea. In the past few decades, many wildlife passages have been constructed to reduce vehicle collisions involving wildlife species. However, few studies have assessed the habitat suitability of target wildlife species when locating the construction sites of wildlife passages. Target species rarely use wildlife passages if built in an inappropriate location. Therefore, a quantitative habitat model is required to find suitable sites for wildlife passages that can connect the fragmented forest patches of wildlife habitats in Korea. In this study, the wild boar was selected as the target species, and six environmental variables (percentage of Quercus forest, slope aspect, distance to roads, water accessibility, forest stand age and density) were measured. The habitat model for wild boars was developed with a Delphi survey, and habitat suitability maps were delineated for the provinces of Gangwon-do and Jeollanam-do. In this study, 298 and 64 boars were observed in Gangwon-do and Jeollanam-do, respectively. Observations of wild boars derived from the second nationwide natural environmental survey were used to evaluate the habitat model. Habitat suitability maps that superimposed existing road networks suggested that wild boar habitats were severely fragmented in both provinces, particularly in Gangwon-do. To connect the fragmented habitats and prevent wildlife-vehicle collisions, this study proposes 11 and 5 wildlife passage sites in Gangwon-do and Jeollanam-do, respectively.

  • Objectives: This study was conducted to determine factors related to glycemic control among Korean patients with diabetes. Methods: Data was collected from the Fourth (2007-2009) Korea National Health and Nutrition Examination Survey (KNHANES) which was a nationwide, cross-sectional survey. The study participants who are available for hemoglobin A1c (HbA1c) were 1,441 patients with diabetes aged 30 years and older. Poor glycemic control was defined as $HbA1c{\geq}7.0%$. Data were analysed using logistic regression. Results: The proportion of patients with the poor glycemic control ($HbA1c{\geq}7.0%$) was 49.5%. After adjusting for confounding factors, younger aged persons (30-49 years) were less likely to control the blood glucose than older aged persons (60-69 years) (Adjusted OR=0.533, 95% CI [0.295-0.960]) and longer duration of diabetes was positively related to poor glycemic control (Adjusted OR=2.018, 95% CI [1.418-2.873]). Conclusions: Age and duration of diabetes were significantly related to blood glucose control. Therefore, considering these factors is helpful for developing a strategy to improve blood glucose control in diabetes.

  • Timber inventory is a good starting point for developing strategies to effectively manage the timberland. In the sale of timberland, pricing is mostly based on this inventory. For a small timberland, inventory by conventional ground survey could be possible. In the case of large and nationwide business transactions, swift and inexpensive inventory is worth to be considered as the conventional methods require more experienced man power, money and time. In the present study, it was aimed to identify the chronicle of timberland such as changes that has occurred owing to silvicultural activities and by other means using the historical aerial photography and satellite data. Historical aerial photos from National Aerial Photography Program (NAPP), National High Altitude Photography (NHAP), Survey Photography and Landsat satellite data were used. Orthophotos were constructed using the DOQQ and DEM from USGS. Simple photo interpretation technique was employed to classify the orthophoto and satellite data. The plantation area was classified into softwood, mixed and hardwood. The timber age and the corresponding acreage details and the changes were also estimated. The result of this study could be more useful to the timberland buyers to better understand the chronicle of timberland of their interest prior to transactions.

  • A nationwide nutrition survey began when the Democratic People's Republic of Korea (DPRK) requested assistance from international relief organizations in 1997 due to flooding in 1995-1996, followed by the worsening food shortage peak in 1997. According to reported data for the 15 years since the active intervention and assistance from international societies, the malnutrition and mortality rates of children in the DPRK have improved. However, the prevalence of the stunting reported in the latest 2012 report is 27.9%, which is still a moderate-severe level, and worrisome in terms of international standards. In particular, the prevalence in Ryangangdo, which is regarded as the worst region in the DPRK, is 39.6%, which is a very high level of stunting. To alleviate such regional deviation will be a major task for future assistance. In addition, one cannot emphasize too highly the importance of early nutritional assistance for pregnant women and infants, considering that the recovery from stunted growth is low after two years of age, and the aftereffects would continue for the rest of their lives.

  • This study was conducted to explore socio-demographic influences on eating behaviors among adolescents in Korea. Data were obtained from the Eleventh Korea Youth Risk Behavior Web-based Survey (2015 KYRBS), a nationwide representative sample of 3,532,149 middle and high school students. The data were analyzed by descriptive analysis, t-test, and logistic regression based on complex sample design using SPSS 20.0 statistics. The results showed that intake frequency of soda, fast food, and instant noodles was higher in male than female students (P<0.001). Additionally, the frequency of eating breakfast, fruits, vegetables, and milk was higher among high school students than middle school students (P<0.001). Higher levels of economic status were associated with less skipping breakfast. Adolescents with mothers that had higher levels of education were more likely to be frequent consumers of fruits, vegetables, and milk, and to eat breakfast.

  • This study attempted to analyze the collection management process and its requirements for public libraries. The survey was designed to examine the detailed collection management guidelines and to grasp its requirements varying across different types of public libraries. The respondents to the survey were librarians who are responsible for managing collections in public libraries which achieved excellence in the 2008 nationwide library management assessment. The study results indicated that most public libraries do not have organized collection management guidelines covering the whole collection management area. In addition, small libraries such as those in hospitals, armies, and prisons have difficulties in managing collections since they do not have proper collection management guidelines.

  • Currently, Japan is undertaking a nationwide project to measure and map radioactive contamination around Fukushima, as part of the efforts to restore normalcy following the nuclear accident. The Japan Atomic Energy Agency (JAEA) manages the Fukushima Environmental Safety Center, located approximately 20 km north of the Fukushima Daiichi nuclear power plant in Minamisōma City, Fukushima Prefecture. In collaboration with the JAEA, this study involved conducting comparison experiments and analyses with radiation detectors in high radiation environments, a challenging task in Korean environments. Environmental radiation surveys were conducted using three types of detectors: CZT, NaI(Tl), and LaBr3(Ce), across two contaminated areas. Dose rate values were converted using dose rate conversion factors for each detector type, and dose rate maps were subsequently created and compared. The detectors yielded similar results, demonstrating their feasibility and reliability in high radiation environments. The findings of this study are expected to be a crucial reference for enhancing the verification and supplementation of procedures and methods in future radiation measurements and mobile surveys in high-radiation environments, using these three types of radiation instruments.
