Purpose: Trauma is one of the most common and lethal causes of death in Korea, especially in people under the age of 40. However, a considerable percentage of trauma patients are lost each year due to the scarce resources of the trauma system. The purpose of this study was to determine the recognition of trauma and trauma system. Methods: From April 8th to 22nd, 2014, visitors and in-patients in our medical center were interviewed and surveyed with a questionnaire, which included 28 questions regarding the trauma system, such as the most common cause of death, the locations of trauma centers, the importance of trauma centers, and consent for supporting trauma centers financially. Results: The majority of the respondents recognized trauma as a common cause of death; this was particularly true for people younger than 40. Most respondents' expectancy for the optimal time for trauma patient transport was high, recognizing that major trauma patients should receive urgent care. The respondents felt that trauma centers are important and needed, just as much as police stations and libraries are. Among 178 respondents, 140 (80.5%) were willing to financially support the trauma system. Conclusion: The respondents were aware of the seriousness of trauma and generally agreed on the need for trauma centers. In order to meet the needs and the demands of the people, and to reduce preventable death rate, the trauma system should be improved not only in quality but also in quantity with better and more facilities and manpower, with the aid of publicity from trauma organizations and funding from the government.

The aim of this study is to survey the eating habits and nutritional knowledge of children in Pusan, with a view to uncovering problems and their underlying causes and cultivating desirable dietary habit and nutrition for children. Three hundred and fifty six elementary school students were asked questions about their eating habits and nutritional knowledge as well as general information about their personal characteristics. The results showed: 1. Only 53.5% of the subjects had breakfast every day. Seventy-six percent of the subjects had dinner every day. Only 40% of the children took meals and talked with family at both breakfast and dinner. Thus there was little opportunity for dietary guidance by parents. 2. About half of the subjects answered that their appetite decreased after eating snack foods between meals. A third of the subjects liked the baked goods as snacks. Because of their high sugar and fat content, they can damage children's health, resulting in child diabetes and tooth decay. For this reason, careful education is necessary to allow children to be able to select snack foods that are appropriate in kind and quantity. 3. About 85% of the subjects had an unbalanced diet. Therefore systematic nutrition education at school is necessary to instill in children the value of balanced diet. 4. Children preferred rice to other cereals as a staple food. They disliked kimchi, seasoned and blanched foods and salads as subsidiary foods. It is therefore necessary to teach children systematically the nutritional advantage of cereals and vegetables and to heighten their awareness of Korean food culture. 5. Children had a low level of nutritional knowledge. The knowledge of specific nutrients was lower than that of foods. In conclusion, systematical educational programs need to be developed at elementary school. These should include information about achieving a balanced diet, good eating habit, meal management and Korean dietary culture. Nutritional education at home must be emphasized.

The objective of this study was to assess the reliability and validity of food security measures, which was developed based on the US household food security survey module (US HFSSM) with content validity in the Korean population. The reliability and validity were assessed by internal consistency, construct validity and criterion-related validity. The study included 446 households. Among those, 46.2% were households with children. The proportion of food insecure households was 33.3%. Among those, 35.4% and 64.6% households were food insecure with hunger and without hunger, respectively. The Cronbach's alpha coefficients were 0.84 and the infit value by the Rasch model analysis ranged from 0.68 to 1.43. The scale item response curves by food insecurity severity explained well the nature and characteristics of food security, indicating the highest proportion of "yes" for the items on diet quality, followed by those with diet quantity. The result of criterion-related validity showed that food insecurity status was significantly related in a dose-response manner with the household income level, food expenditure, subjective health state, subjects' educational level. Household food security status was also related to dietary diversity regarding protein foods, fruits and fruit juice, and milk and dairy product. These findings suggest that the food security instrument is reliable and valid and would be used to assess food security status in the Korean population.

River channel dredging and riparian development have been influenced morphology and quantity of natural river habitat. We compared distribution of riverside land and alluvial island in the Nakdong River with field survey and remote sensing analysis after the 4 Large River Project in South Korea. We digitized geomorphological elements, includes main channel, riverside land, and alluvial island by using georeferenced aerial photos taken in pre-dredging (2008) and post-dredging (2012) periods. Field survey was followed in 2012 for a ground truth of digitized boundaries and identification of newly constructed wetland types such as pond, channel, branch, and riverine type. We found that during the dredging period, riverside land and alluvial island were lost by 20.2% and 72.7%, respectively. Modification rate of riverside land was higher in the section of river kilometer 50~90, 140~180, and 210~270. Alluvial island had higher change rate in the section of river kilometer 50~70, 190~210, and 270~310. Average change rate for the riverside land and alluvial island was $-1.02{\pm}0.14km^2{\cdot}10km^{-1}$ and $-0.05{\pm}0.05km^2{\cdot}10km^{-1}$, respectively. Channel shaped wetlands (72.5%) constituted large portion of newly constructed wetlands.

Background: In recent events of the coronavirus disease 2019 (COVID-19) pandemic, computed tomography (CT) scans are being globally used as a complement to the reverse-transcription polymerase chain reaction (RT-PCR) tests. It will be important to be aware of major organ dose levels, which are more relevant quantity to derive potential long-term adverse effect, for Korean pediatric and adult patients undergoing CT for COVID-19. Materials and Methods: We calculated organ dose conversion coefficients for Korean pediatric and adult CT patients directly from Korean pediatric and adult computational phantoms combined with Monte Carlo radiation transport techniques. We then estimated major organ doses delivered to the Korean child and adult patients undergoing CT for COVID-19 combining the dose conversion coefficients and the international survey data. We also compared our Korean dose conversion coefficients with those from Caucasian reference pediatric and adult phantoms. Results and Discussion: Based on the dose conversion coefficients we established in this study and the international survey data of COVID-19-related CT scans, we found that Korean 7-year-old child and adult males may receive about 4-32 mGy and 3-21 mGy of lung dose, respectively. We learned that the lung dose conversion coefficient for the Korean child phantom was up to 1.5-fold greater than that for the Korean adult phantom. We also found no substantial difference in dose conversion coefficients between Korean and Caucasian phantoms. Conclusion: We estimated radiation dose delivered to the Korean child and adult phantoms undergoing COVID-19-related CT examinations. The dose conversion coefficients derived for different CT scan types can be also used universally for other dosimetry studies concerning Korean CT scans. We also confirmed that the Caucasian-based CT organ dose calculation tools may be used for the Korean population with reasonable accuracy.
