The purpose of this study was to examine elderly people`s oral health behaviors and education needs. The subjects in this study were 195 senior citizens who were users of senior cultural centers and senior welfare agencies in Seoul and Incheon. After a survey was conducted, the collected data were analyzed by the statistical package SPSSWIN 19.0. The findings of the study were as follows: 1. Gender, academic credential and monthly mean income were identified as the general characteristics to impact on their oral health attitude. 2. The senior citizens who ever received oral health education had a better knowledge(p<0.05) and took a better attitude(p<0.01). 3. As for a time for toothbrushing, many brushed their teeth after breakfast(74.9%) and dinner(71.8%). Utilized Oral hygiene devices were interdental brushes(21.5%), dental floss(13.8%). As many as 62.5% felt they had a dry mouth, and the most prevalent way for them to cope with it was drinking water often(68.2%). 79.5% didn`t get their teeth cleaned on a regular scaling. 4. The rate of regular scaling was higher in the elderly groups that ever received oral health education and whose knowledge scores was above the average(p<0.05). 5. In relation to the necessity of oral health education, 87.2% felt the need for that, and as many as 79.0% intended to receive that education. Their favorite period of education was 6months(41.0%), and the greatest group hoped to receive that education for an hour(55.4%). The largest group wanted to learn about prevention of oral diseases, followed by toothbrushing, denture management, dry mouth. Given the findings of the study, senior welfare centers and senior cultural centers should offer oral health education programs as part of lifelong education to provide systematic and prolonged education for the elderly to improve their oral health care to promote their oral health.

The purpose of the present study was to evaluate the fit factors and total inward leakage (TIL) of commercially-available face masks in Korea. We selected a total of six face masks: surgical, KF AD, KF80, KF94, KF99 and N95. Six male subjects participated in a fit test, while ten subjects participated in TIL test. Among the subjects, only three subjects participated in both tests and the relationship between fit factor and TIL was analyzed using data from the three subjects. The results showed that 1) no relationship between filtration of mass and fit factor was found, 2) greater filtration level, smaller TIL; 3) smaller fit factor, greater TIL (r=0.498, p<0.05). However, the correlation was not that great, which was attributed to the differences in mask design (folded or flat type vs. cup type; ear loop vs. head band) and face types. In order to minimize leakage rate when wearing face masks, a cup type with seal and head bands is recommended rather that folded types with ear loops. It needs that the fit test should be a mandatory test for hospitals or occupational fields where workers should wear their own face masks to protect then from dusts or biological hazards. Also, the development of Korean face test panel should be precedent to conduct a fit test.

Seoul Arts High School was established in 1953, in order to train professional artists. Today, there are 26 arts high schools in Korea. The ultimate purpose of the establishment of arts school is to train potential professional artists. However, the current operation of the curriculum in arts high schools reveals that it is designed for university entrance exam-oriented education. This study aims to analyze the curriculum in 6 arts schools in Seoul and Gyeonggi-do, where Korean dance, modern dance, and ballet majors are offered, and to study ideal curriculum for arts high school, to foster artists who can integrate thinking and creativity. The following issues were identified in terms of the operations of the integrated curriculum for enhancing creativity. First, the operation of the integrated curriculum was insufficient in conjunction with regular course and professional course(dance-major course). Second, the operation of the curriculum for enhancing creativity was insufficient in conjunction with theory courses and practical courses among dance-major curriculum. Third, the operation of the curriculum related with creativity to develop movement was insufficient because arts schools operate university entrance exam-oriented curriculum. The future directions for improving the above-mentioned issues and for improving creativity through integrated curriculum are as follows. First, it is necessary to pursue integrated curriculum of regular courses such as history, literature, and society, and to pursue creative curriculum in order to improve creativity. Second, it is necessary to pursue integrated curriculum with other arts curriculum such as art, music, and acting, considering dance is an embodied art. Third, it is necessary to operate integrated curriculum to encourage and develop creative movement. Fourth, arts high schools operate a three-year curriculum in total. Therefore, it is necessary to operate integrated curriculum progressively in order to improve creativity.

This study explores the effects of facemasks on respiratory, thermoregulatory, cardiovascular responses during exercise on a treadmill and at rest. Five male subjects (25.8 ± 0.8 y, 171.8 ± 9.2 cm in height, 79.8 ± 28.1 kg in weight) participated in the following five experimental conditions: no mask, KF80, KF94, KF99, and N95. Inhalation resistance was ranked as KF80 < KF94 < N95 < KF99 and dead space inside a mask was ranked as KF80 = KF94 < N95 < KF99. The surface area covered by a mask was on average 1.1% of the total body surface area. The results showed no significant differences in body core temperature, oxygen consumption (VO2), carbon dioxide production (VCO2), heart rate or subjective perception among the five experimental conditions; however, cheek temperature, respiratory ventilation and blood pressure were greater for KF80 or KF94 conditions when compared to KF99 or N95 conditions (p<0.05). The differences among mask conditions are attributed to the dead space or specific designs (cup type vs pleats type) rather than the filtration level. In addition, the results suggest that improving mask design can help mitigate respiratory resistance from increased filtration.

정재연(Jae-Yeon Jung),손순룡(Soon-Yong Son),이종석(Jong-Seok Lee),유병규(Beong-Gyu Yoo) 대한방사선과학회(구 대한방사선기술학회) 2011 방사선기술과학 Vol.34 No.4

척추촬영법은 의료기관별로 상이하고 각종 대학 및 국가시험을 위한 교재 등에 상이하게 기술되어 혼선을 빚고 있는 실정이다. 이에 동일한 환자의 선자세와 누운자세에서 촬영한 영상을 바탕으로 각 자세에서 척추측만각과 척추전만각의 차이를 비교함으로써 임상 및 관련기관, 참고서적에 가장 적절한 촬영자세를 정립하여 제시하고자 하였다. 2009년 3월부터 2011년 9월까지 척추질환 환자 중 수술적 치료를 받지 않은 85명을 대상으로 Cobb’s method를 이용하여 척추전만각(lordortic angle) 및 척추측만각(scoliotic angle)을 측정하였다. 각각의 측정자료는 t-test(SPSS 18)를 이용하여 유의성을 분석하였으며, 임상의 실태 파악을 위해 서울소재 10곳의 대학병원을 대상으로 척추촬영의 자세와 시행근거를 설문으로 조사하였다. 척추측만각의 측정 결과, 선자세가 바로누운자세보다 평균 20.98% 증가하였으며, 통계적으로 매우 유의한 차이를 보였다(p<.01). 척추전만각은 지지대잡은자세가 측와위자세보다 29.3% 증가하였으며, 통계적으로 매우 유의하였다(p<.01). 의료기관의 실태 결과, 누운자세촬영이 70.0%로 선자세촬영의 30.0%보다 월등하게 나타났다. 결론적으로 선자세촬영은 누운자세촬영보다 척추측만각 및 척추전만각이 증가하여 임상적 진단과 치료에서 중력이 가해진 선자세 촬영의 중요성과 일치하였으므로 임상의 검사자는 그 차이를 인식하여 필히 정확한 선자세에서 촬영이 요구된다. Since the spine radiography were explained differently at every several hospitals and textbooks. the technique has not been accurately defined and interfered each other. We would like to define the most appropriate positioning for clinical cases, and reference books, by comparing scoliotic angle and lordotic angle. From Mar 2009 to Sep 2011, 85 patient cases were studied, who had not been undergone surgical treatment among spondylopathy patients. Scoliotic angle and lordotic angle were measured, using Cobb’s method. We analyzed statistically using t-test(SPSS 18), and evaluated spine general radiography position. Moreover, we researched on the actual condition at 10 university hospitals in Seoul. The results of scoliotic angle measurement, the value at erect position showed 20.98% higher than supine position, and it has statistical significance (p<.01). In lordotic angle measurement, the value at neutral holding position represented 29.3% higher than supine position, and it also has statistical significance(p<.01). The results of clinical survey, supine posine(70.0%) took much higher possession than erect position(30.0%). In conclusion, compare to supine position, erect position shows increased scoliotic and lordotic angle. It was agreed with the importance of clinical erect position radiography, which gravity affects. So clinical radiologist must recognize the difference, and conduct an accurate study.

정재연(Jae yeon Jung),김경민(Kyeong min Kim),강정훈(Jung hun Kang),이광원(Kwang won Lee) 대한CT영상기술학회 2016 대한CT영상기술학회지 Vol.18 No.2

Purpose : Recently, as the society progresses towards population ageing, a number of metallic implant surgeries are being performed. This study is investigating metal artifact reduction methods with various concentrations of contrast medium by combining contrast medium and normal saline for computed tomographic (CT) scan. Subjects and Methods : SOMA TOM SENSATION16(Siemens, Germany) is used for the CT equipment, and the sample, which is the material like titanium used for TKR in orthopedics, is fixed between two normal salines. For the mixture of contrast medium and normal saline, 100cc contrast medium (concentration of 300) + 400cc normal saline, 50cc contrast medium (concentration of 300) + 450cc normal saline, 10cc contrast medium (concentration of 300) + 490cc normal saline, 100cc contrast medium (concentration of 370) + 400cc normal saline, 50cc contrast medium (concentration of 370) + 450cc normal saline, and 10cc contrast medium (concentration of 370) + 490cc normal saline are used. The mixture is placed on top and bottom, and left and right of titanium fixed with normal salines in order, and HU values of CT and standard deviations with respect to 120kVp/250mAs/slice 0.75mm, 1.5mm, 140kVp/250mAs/slice 0.75mm,1.5mm, and 140kVp/350mAs/slice 0.75mm, 1.5mm (tube voltage/tube current/slice thickness) are measured and compared with HU value obtained by measuring ROI at 1.5cm distance in 12 O clock and 6 O’clock from the center of titanium. Results: When the mixture of 10cc contrast medium (concentration of 300) + 490cc normal saline was used top and bottom, and left and right, and when tube voltage/tube current/ slice thickness was 140kVp/250mAs/slice 0.75mm, HU value of CT and standard deviation (SD) of metal artifact were 18/27 and 14/25, respectively, showing the highest reduction. For tube voltage, 140kVp showed higher reduction than 120kVp, and for tube current, 250mAs showed higher reduction than 350mAs. Reduction was shown when the slice thickness was 0.75mm. When the mixture of 100cc contrast medium (concentration of 370) + 400cc normal saline was used in 120kVp/250mAs/slice 1.5mm, reduction measure was the lowest. Conclusion : HU value of metal artifact from CT scan showed the highest reduction when the mixture of 10cc contrast medium (concentration of 300) + 490cc normal saline was used in 140kVp/250mAs/slice 0.75mm. Although correction value of HU value shows some large or small differences depending on the amount of artifact for each CT scan, the results are all improved in a positive way. Visual identification of CT scan made the difference in quality of scan seemed much bigger, compared to identification of the numerical values. If this study method is applied to the examination of existing metal patients, the quality of image can be improved. 목적 : 최근 인구의 고령화가 진행되면서 많은 금속 인공물 삽입술이 시행되고 있다. 전산화단층영상에서 조영제와 생리식염수를 혼합하여 조영제 농도를 달리해 Metal Artifact 인공물에 대한 감소방안을 알아보고자 하였다. 대상 및 방법 : CT장비는 SOMATOM SENSATION16(Siemens, Germany)를 사용하였고, 정형외과 TKR에 사용되는 Titanium과 같은 재질의 샘플을 생리식염수 2개의 사이에 고정하였으며 혼합물로는 조영제와 생리식염수를 혼합하여 제작한 조영제 농도 300 100cc+생리식염수 400cc, 조영제 농도 300 50cc+생리식염수 450cc, 조영제농도 300 10cc+생리식염수 490cc, 조영제 농도 370 100cc+생리식염수 400cc, 조영제 농도 370 50cc+생리식염수 450cc, 조영제 농도 370 10cc+생리식염수 490cc를 이용하였다, 생리식염수로 고정한 Titanium을 상·하, 좌·우로 혼합물을 순서대로 올려놓고 120kVp/250mAs/slice 0.75mm, 1.5mm, 140kVp/250mAs/slice 0.75mm, 1.5mm, 140kVp/350mAs/slice 0.75mm, 1.5mm, 관전압, 관전류 슬라이스 두께에 따른 CT HU값 및 표준편차를 Titanium 중심부에서 12시 방향과 6시방향의 1.5cm거리에서 ROI를 측정하여 HU값을 비교 측정하였다. 결과 : 혼합물 조영제 농도300 10cc+생리식염수 490cc를 상·하, 좌·우 사용하였을 때와 140kVp/250mAs/slice 0.75mm일 때 Metal Artifact 인공물의 CT HU값과 표준편차(standard deviation ; SD)는 36/36, 27/40으로 감소효과가 가장 높게 나타났다. 관전압은 140KvP가 120KvP보다 감소효과가 있었으며, 관전류는 250mAs일때 350mAs보다 감소효과가 있었다. slice두께는 0.75mm일 때 감소효과가 있었다. 조영제 농도 370 100cc+생리식염수 400cc, 120KvP/250mAs/slice 1.5mm 일 때 감소효과가 가장 낮게 측정되었다. 결론 : 혼합물 조영제 농도 300 10cc+생리식염수 490cc, 140KvP/250mAs/slice 0.75mm일 때 Metal Artifact 인공물의 CT HU값의 감소효과가 가장 높게 나타났다. 각 영상의 Artifact 앙에 따라 HU값 보정치는 크고 작은 차이를 보이지만, 결과는 모두 긍정적인 방향으로 개선되었음을 알 수 있었다. 육안으로 CT 영상을 확인할 때 영상의 질 차이가 수치상으로 느끼는 것보다 훨씬 크게 느껴졌다. 기존의 Metal 환자 검사 시 본 연구방법으로 적용을 한다면 Image Quality를 향상시킬 수 있을 것이다.

Objectives: The purpose of the study is to investigate the awareness toward use and service contents of long term care for the elderly. Methods: A self-reported questionnaire was completed by 296 adults from August 13 to October 20, 2014. The questionnaire consisted of general characteristics of the subjects, awareness toward long term care insurance for the elderly, awareness toward long term oral health care services, use of long term care service and use intention for the long term care insurance. Data were analyzed by SPSS 18.0 program. Results: Those who were aware of the long term care insurance accounted for 55.4 percent. Approximately 50 percent of the respondents recognized long term care service items, home visit care, home visit bathing, and home visit nursing. Most of the respondents had information of long term care services by way of mass media and direct contact. Only 13.4 percent of the respondents were aware of the oral health service in the long term care insurance. The subjects were aware of denture cleaning, oral cleaning and oral health education out of oral health service in order; and oral health services that needed to be offered were denture cleaning, oral health education and professional toothbrushing. They reported that dental hygienists were the most important manpower that offered the efficient oral health care services. They answered that professional manpower and financial support are required for oral health services. The positive thinking to long term care insurance accounted for 89.2 percent and 91.3 percent had use intention for oral health services. Conclusions: Many elderly people have mastication or dysphagic problems due to systemic diseases. Therefore, it is necessary to announce the long term care insurance and long term care services for the elderly people.
