This study was performed to evaluate the differences in blood pressure, sodium intake and dietary behavior changes according to the extent of session attendance on sodium reduction education program for pre-hypertensive adults in a public health center. Sodium reduction education program consisted of 8 sessions for 8 weeks. Fifty three patients who completed the pre and post nutritional assessments were classified into 2 groups according to the session attendance rate. Nineteen participants who attended the education program 3 times or less (≤ 3) were categorized into the less attendance (LA) group and 34 participants attended 4 times or more (≥ 4) into the more attendance (MA) group. Blood pressure, anthropometric measurements, serum lipid profile, nutrient intakes including sodium, nutrition knowledge and dietary behavior score were assessed before and after the nutrition education program. Mean sodium intakes (p < 0.001), systolic/diastolic blood pressure (p < 0.001), and weight (p < 0.001) were significantly decreased in the MA group after sodium reduction education program. Compared to the MA group, mean sodium intakes, systolic/ diastolic blood pressure were not significantly changed after the education program even with significantly increased nutrition knowledge (p < 0.05) and dietary behavior score (p < 0.01) in the LA group. It appears that pre-hypertensive adults need to attend the sodium reduction education program for at least 4 times or more to gain beneficial effects from the intervention. Positive feedback of healthcare team or offering more cooking classes may be needed to raise the attendance rate in the sodium reduction education program.

We develop guidelines for the quality assurance of radiation treatment planning systems (TPS) by comparing and reviewing recommendations from major countries and organizations, as well as by analyzing the AAPM, ESTRO, and IAEA TPS quality assurance guidelines. We establish quality assurance items for acceptance testing, commissioning, periodic testing, system management, and security, and propose methods to perform each item within acceptable standards. Acceptance includes tests of hardware and network environments, data transmission, software, and benchmarking as specified by the system supplier, and apply the IAEA classification criteria. Commissioning includes dosimetric and non-dosimetric items for assessing TPS performance by applying the AAPM classification criteria and the latest technical items from the IAEA. Periodic quality assurance tests include daily, weekly, monthly, yearly, and occasional items by applying the AAPM classification criteria. System management and security items include the state and network connectivity of TPS, periodic data backup, and data access security. The guidelines for TPS quality assurance proposed in this study will help to improve the safety and quality of radiotherapy by preventing incidents related to radiotherapy.Keywords: Radiation treatment planning system, Acceptance test, Commissioning, Quality assurance Copyright © 2017 Korean Society of Medical Physics CC This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/bync/4.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. IntroductionBecause of the rapidly aging population, the number of cancer patients has increased continually by 5.5% each year. were over 1,000 instances of patients receiving the wrong radiation treatment. 4)The key reasons behind the incidents related to radiation treatment planning included an insufficient understanding of the radiation treatment planning system (RTPS), a lack of commissioning, and no verification of independent calculations, and that educational training and quality assurance processes were not properly managed. However, currently quality assurance guidelines for RTPS do not exist. Thus, in this research, to improve the quality assurance of treatment planning, which when poorly executed is one of the causes behind main radiation therapy incidents and accidents, the current state of international quality assurance is analyzed, and RTPS quality assurance guidelines are proposed. Materials and Methods Current state of foreign radiation treatment planning quality assuranceRadiation treatment planning and the current state of QA from related foreign organizations were analyzed and organized, from which relevant standards and procedures were prepared. Several quality control items and methods were separated by type, compared, and evaluated. These Radiation treatment planning system quality assuranc...
Objectives: This study was performed to evaluate the consumer education program for reducing sodium intake based on social cognitive theory (SCT) and investigate consumer perceptions of environmental, cognitive and behavioral factors. Methods: Consumers (n=4,439) were recruited nationwide in Korea to participate in a nutrition education program for reducing sodium intake which was targeted on senior housewives (SH), parents (P), and office workers (OW). Questions regarding main factors of SCT were asked both before and after the education program. Results: SH and P recognized external social efforts and information to reduce sodium including nutrition labeling more than OW. The main barriers to practice reducing sodium intake were limited choice of low sodium food and menu, interference with social relationship when dining with others, and limited information, knowledge and skills. SH had lower barriers to practice reducing sodium intake and OW perceived 'preference to soup or stew' and 'preference to Kimchi, salted fish and fermented sauces' as barriers more than other groups at the baseline. Less than 50% of participants knew the relationship between sodium and salt, sodium in nutrition labeling, and recommended sodium intake. In addition, OW had little knowledge for capability to reduce sodium intake and lower self-efficacy to practice compared with SH and P. After education, positive outcome expectations such as lowering blood pressure, prevention of cardiovascular disease and osteoporosis were increased and barriers to practice reducing sodium intake were decreased in all groups (p < 0.05). The knowledge for behavioral capability and self-efficacy to reduce sodium intake were also improved but OW had still lower scores compared with other groups. Conclusions: These results suggested that nutrition education programs could be an effective tool to impact general population by facilitating awareness and increased capability to reduce sodium intake.
Dietary habit of excess sodium consumption is formed mainly by excessive salt intake from the younger age and this may lead to hypertension, stroke, and stomach cancer. This study was performed to estimate the salt content in kindergarten meals and provide basic data on meal providers' dietary attitude to sodium intake for nutrition education. We collected data on161 food items from 16 institutions in Gyeonggi-do and salt content was calculated from salinity and weight of individual food items. The average salt content from lunch meals was 2.2 g, which was about daily adequate intake of sodium for children aged 3 to 5 years old. Greatest contributor to the salt content in a meal was soup and stew (47.8%). The most salty dishes were sauces and kimchi followed by stir-fried food, deep-fried food, braised food, and grilled food. The salt content was higher in soup and stew despite of low salinity, due to the large quantity per serving. The salt contents of soups and kimchi were 40.6% and 14.3%, respectively of the total salt content in dish groups. Staff members and caregivers at home who prepared food for the child showed preference for one-dish rice meal, dried fish and salted mackerel, and broth when eating soup, stew, and noodles. Caregivers showed higher sodium index score and had higher preference for processed food such as Ramen, canned food, and ham compared with staff members (p < 0.05). These results suggested that monitoring salt content of kindergarten meals and nutrition education for those prepare meals for children are needed to lower sodium intake in childhood.

Purpose : We investigated the risk factors related to the development and aggravation of allergic rhinitis, which is associated with residential environment and lifestyle habits of children residing in Incheon.Methods : A total of 182 children diagnosed with moderate to severe allergic rhinitis and 67 healthy children were enrolled. A detailed questionnaire of the environmental characteristics and the dietary habits were completed by the parents. Further, skin prick tests with 14 common allergens were performed.Results : The mean age of the children with allergic rhinitis and healthy control was 8.2±2.8 and 9.4±2.0 years, respectively. The presence of indoor mold was associated with an increased risk of development of allergic rhinitis. (adjusted odds ratio [aOR], 4.26; 95% confidence interval [CI], 1.96-9.27) Among the food groups, there was no significant difference of the daily intake of milk and yogurt between the patients and the controls. However, daily intake of vegetables, except Kimchi, and daily intake of fruits or fruit juice were associated with a decreased risk of allergic rhinitis. (aOR, 0.43; 95% CI, 0.43; 95% CI, respectively) Conclusion :The results indicate that an indoor dampness is one of the risk factors of development and aggravation of allergic rhinitis. Control of indoor humidity and daily intake of fruits and vegetables can prevent the development and control symptoms of allergic rhinitis. [Pediatr Allergy Respir Dis(Korea) 2012;22:100-109]
