Background: To prevent contrast agent’s side effects, it is important to provide accurate information about the contrast agent and fulfill the duty of explaining the medication, experience of side effects, and medical history. However, the incidence of safety accidents associated with contrast agents is continuously increasing. Therefore, the objective of this study was to prepare an improvement plan for problems derived by analyzing changes in chemical structure of contrast medium according to radiation and external environment. Method: The chemical structure of the standard sample was analyzed using Nuclear Magnetic Resonance Spectroscopy (NMR) in P contrast agent of Iopamidol preparations used in Korean medical institutions. Samples were obtained by irradiation under 3Gy and 5Gy conditions according to the Photon 10MV, Electron 20MeV condition and the radiation dose according to the radiation and environmental conditions. Contrast agent samples after opening and sealed but expired samples were also obtained. These samples were analyzed and chemical shift values in the 1H-NMR spectrum using NMR analysis were compared. Findings: 1H-NMR analysis results of P contrast medium irradiated with Photon 10MV and 5Gy and sealed but expired P contrast medium samples showed no change in chemical shift. However, there were changes in chemical shift value in P standard sample, showing triple peaks in 1.1-1.2ppm range. In addition, the sample irradiated by Electron 20MeV and 3Gy showed double peaks. The sample irradiated by Electron 20MeV and 3Gy condition showed a single peak in the 3.0-3.5ppm region, demonstrating a change in chemical shift value. In the 1.0-1.4ppm region, P contrast medium standard samples showed triple peaks and opened contrast medium samples showed double peaks in the middle peak among the triplet, demonstrating changes in chemical shift value. Improvements: Changes in chemical structure of contrast agent were observed in contrast medium after electron irradiation and in contrast medium after opening. In this regard, guidelines for the administration of contrast medium should be prepared as soon as possible so that consumers could have accurate information and their right of choice.Keywords

Background/Objectives: The aging population due to increases of average life expectancy elderly population is perceived a serious problem in the medical sector. The objective of this study was to determine the degree of awareness of pressure ulcer in nurses in charge of pressure ulcer management in medical institutions and to provide basic data for setting guidelines.
Method/Statistical Analysis:A survey and analysis were conducted on 40 nurses in charge of nursing care at a nursing hospital. The survey tool was developed by quoting a pressure ulcer prevention management tool developed by Moore and Price. The survey was conducted in a face-to-face manner, explaining the purpose of the study directly. A total of five questions are recognized as pressure ulcer management, and the reliability is Cronbach’s α = .785 and consisted of a five-point Likert scale. The general characteristics are gender, age, work experience, Education, and hospital size of nursing hospital, with total five questions and reliability being Cronbach’s α = .654.
Findings: “How much do you know about the pressure ulcer?” showed the highest ‘Yes’ of 30%. In the pressure ulcer management knowledge section, “Do you know about changing your bed posture at least every two hours?” showed the highest ‘very yes’ of 82.5%. “Do you know the standard of management when a pressure ulcer occurs?” showed 45.0% of ‘Yes’ and “Do you know the factors involved in the pressure ulcer?” with 47.5%. “Do you know about the relationship between humidity and temperature among the factors involved in the pressure ulcer?” showed 57.5% (23).
Improvements/Applications: The results of this study show the degree of pressure ulcer management by nursing hospital nurses in charge of the pressure ulcer management. Knowledge of the pressure ulcers was high, but low awareness of the factors involved in the management standards emerged. It is expected that this data will be used as basic data for setting up education and management measures for the management of the pressure ulcers in the future.

Background/Objectives: Although smart phone is known for its convenient functions and portability, it is also causing smart phone addiction which is becoming a serious social issue. The objective of this study was to determine the degree of smartphone dependence in university students majoring in radiology and analyze the influence of smartphone addition on their interpersonal relationships.
Method/Statistical Analysis: : A questionnaire was used to survey 431 university students about the use of smartphone. The questionnaire had 26 questions. Each question was evaluated with a 5-point Likert scale. Its Cronbach’s α value was 0.893. Students’ satisfaction for interpersonal relationship was determined according to their situation. Three additional socio-demographic characteristics (economic level, addiction, and gender) were also determined. Questions and answers were provided face-to-face.
Findings: Overreliance on smartphones was the highest in living standards with income at the “middle” level with 240 (55.64%) and female students at 184 (42.6%) in gender, higher than 247 (57.3%) for male students. In terms of interpersonal satisfaction, 247 (57.3%) male students showed high levels of satisfaction with each other’s relationships, while in terms of smartphone overreliance, the group of people who are not satisfied (3.545±0.34) showed high levels. Correlation analysis showed a static correlation between sex and smartphone over-dependence (r = .217, p<.001), and there was a negative correlation between smartphone and interpersonal satisfaction (r = -.236, p<.001).
Improvements/Applications: Based on results of this study, a program should be developed to prevent smartphone dependence of students and raise interpersonal satisfaction. Results of this study could be used as basic data necessary for education on smartphone dependence prevention in university students.

Background/Objectives: This study was conducted to investigate the oral health cognition and behavior of 83 children’s parents. The results of this study were as follow. First, the questionnaire consisted of eight items on oral health behavior and three items on parental oral health cognition. Improper oral health care behavior responses resulted, and the necessity of fluoride application of oral health awareness scored lower than the necessity of oral health education and regular dental checkups.
Method/Statistical Analysis: Targeting a total 83 parents at daycare centers in the C region, September 2018-October 2018, this study distributed the home notification, questionnaire, and research consent form to each home through their children. The completed research consent forms and questionnaires were collected by the daycare centers from the children.
Findings: The three times of brushing daily, two-three minutes of brushing each time, and the ‘1/3, 1/2 of the toothbrush for the amount of toothpaste used received the most responses. Many respondents changed their toothbrushes every four weeks. 72.3% of respondents used fluoride toothpaste, and 72.3% of respondents were controlling food and snacks containing sugar. 73.5% of parents were receiving regular oral examination, and 30.0% of parents received it once a year. 84.3% of parents were using secondary oral hygiene products. The average oral health perception was 4.26 while the necessities of fluoride application, regular dental examination, and oral health education averaged 3.59, 4.63, and 4.63 respectively.
Improvements/Applications: It would be necessary to vitalize the oral health project and oral health education for parents and children, and also to have accurate and systematic studies on more inclusive and diverse elements.
