by providing objective information regarding medical radiation for elementary, middle, and high school students in Korea, who are expected to have a high ripple effect in education, and by analyzing behavioral changes in the selection of medical radiation, this study aimed to deduce the basis for educational intervention. The tools used in the study were a questionnaire, including questions about perception, knowledge, attitude, and behavior toward medical radiation; video and Power-point materials for the lesson; simulated radiation diagnosis selection form; and radiation treatment selection form to find out about behavior. A post-test demonstrated that the objective knowledge about medical radiation of all the students turned out to be significantly higher (p<0.000) after the lesson compared to before the lesson. However, there were no statistically significant behavioral changes. Rather, for high school students, the behavior of selecting medical radiography and treatment was significantly lower (p<0.000) after the lesson. For the more impressionable children in the lower grades, the lesson must not only provide an opportunity to understand and pay attention to diverse viewpoints, but also encourage them to make ethical decisions based on value. Since it can be predicted that attitude or behavioral changes through education or publicity can be expected from adults older than high school students, issues regarding dangers like radiation exposure must be treated as an issue of value judgment predicated on multifaceted considerations.

Background: Epidermoid cysts are benign tumors derived from the infundibular portion of hair follicles and thus have a flattened surface epithelium and keratohyaline granules. They can occur at any age but are most frequently reported in adults, and more often occur in men than women. Most epidermoid cyst operations are performed for cosmetic purposes, or to relieve inflammation. The definitive treatment is complete excision or destruction of the cyst. The aim of this study was to improve understanding of epidermoid cysts. Methods: We analyzed 432 cases of epidermoid cyst in 398 patients that underwent complete excision and biopsy between April 2001 and March 2020, according to patient age, patient gender, and lesion location. Results: From all epidermoid cyst excisions performed, 17.6% were for patients in their 40s and 50s, 16.8% for those in their 20s, 16.1% for those in their 30s, 14.6% for those aged 60 or older, 5.0% for teenagers, and 0.5% for those under 10 years. Cases of epidermoid cysts occurred at a men-to-women ratio of about 3:2, with 59.5% of cases in men and 40.5% in women. By lesion location, 65.0% of cases were on the face, 10.9% on the trunk, 7.9% on the scalp, 7.9% on the neck, 4.3% on lower extremities, 3.9% on upper extremities, and 0.2% on genitalia. On the face, 20.8% of cases were on the cheek, 12.7% on the periauricular area, 10.9% on the periorbital area, 6.0% on the frontal area, 5.6% on the mental area, 3.7% on the perioral area, 2.8% on the nasal area, and 2.5% on the temporal area. Conclusion: The proportion of women with epidermoid cysts was higher in our study than in previous studies. Moreover, the results showed that surgery has been on the rise in recent years, with facial surgery being the most common.

Purpose: This study aimed to describe Korean nursing home nurses' perceptions on dysphagia management and their working experiences of older adults with dysphagia. Methods: Using a purposive sampling design, 23 eligible nurses were interviewed as four focus groups from 4 facilities out of nursing homes. The qualitative data from focus group interviews were analyzed using thematic analysis to classify common themes into larger categories. Results: Two main themes on the attributes of caring nursing home residents with dysphagia were 'Need for nursing resources' and 'Need for support'. In addition, four subthemes emerged as a result of analysis: 'need for nursing protocols for assessing and managing dysphagia', 'need for emergency care skills of nurses and nurse assistants', 'need for prompt and accurate management by cooperation of physicians and therapists', and 'need for partnership upon comprehension of visiting family members concerning dysphagia'. Conclusion: Nursing home nurses fully recognized the importance of dysphagia management; however, they experienced substantial barriers due to lack of adequate nursing protocols or partnership with family caregivers, insufficient training for emergency care, and deficient support from medical staff. Development of nursing guidelines tailored to the nursing home context and based on partnership among medical experts and family caregivers is needed.

Purpose: This study aimed to identify the effect of integrated nursing using cognicise and neurofeedback on cognition and α waves among elderly individuals. Methods: This quasi-experimental single group pretest-posttest study included 29 Korean adults aged 65 years or older who participated at a senior welfare center in Y city from February to May 2019. Each integrated nursing session consisted of cognicise (10 minutes) and neurofeedback (20 minutes). Subjects participated twice a week for 10 weeks. Structured questionnaires to assess participants' general characteristics and the Korean version of the Mini-Mental Status Examination for Dementia Screening (K-MMSE-DS) were applied. Alpha waves were measured using BrainMaster. Results: Following the integrated nursing program, alpha waves improved in F3 (t=2.41, p=.023), C3 (t=3.00, p=.006), C4 (t=2.60, p=.015), P3 (t=2.43, p=.022), O1 (t=2.30, p=.029), T3 (t=3.05, p=.005), T4 (t=2.28, p=.030), T5 (t=2.91, p=.007), Fz (t=2.30, p=.029), Cz (t=2.73, p=.011), and Pz (t=2.23, p=.034). Most subjects experienced improvement in concentration after participating in the intervention. Conclusion: This study provides evidence for the use of a neuroscientific approach including brain wave measurement to improve cognitive health among community-living elderly people.

본 연구의 목적은 이중과업 방법론(dual task methology)을 사용해서 젊은 사람과 노인을 대상으로 독립된 두 사건(two separate concurrent events)을 동시에 수행하는데 요구되는 주의력에 대한 분석과 노인에서의 특징적 차이를 찾는 것이다. 본 실험은 대상자가 힘판(force plate) 위에서 장애물(10cm) 보행시에 경피자극(cutaneous stimulation)에 대하여 마이크로 스위치(micro-switch)를 사용하여 반응하면서 시행되었다. 힘판과 시간(temporal events) 그리고 반응시간(reaction time)에 관한 자료들은 1000 Hz의 주파수로 수집되었다. 반응시간은 대상자들이 서 있는 상태(baseline) 장애물 보행시(dual task)에서 수집되었다. 반응시간은 아중과업 조건에서 대상자 모두에게서 긴 것으로 나타났으며 특히 노인에서 정상 성인보다 반응시간이 긴 것으로 나타났다. 이중과업 조건 하에서 노인 대상자가 정상 성인에 비해 발가락이 장애물에 닫지 않고 통과할 수 있는 공간, 즉 토우 클리어런스( toe-clearance)와 슬관전 굴곡(knee flexion) 각도가 훨씬 큰 것으로 나타났다. 이중과업 조건하에서 모든 대상자가 족관절 배측굴곡(ankle dorsiflexion) 각도를 감소시키는 것으로 나타났다. 노인들은 젊은 대상자들보다 훨씬 더 긴(124 ms) 유각시간을 보여 주었으며 정상 장애물 보행시 유각 시간은 이중과업보다 50 ms 긴 것으로 나타났다. 이러한 보행 특성의 차이는 노인대상자들이 젊은 대상자들보다 장애물 보행시에 이중과업의 영향을 더 받았기 때문인 것으로 판단된다. 이중 과업 시행시 이러한 토우 클리어런스의 감소와 장애물 통과시에 보행 속도의 증가는 아마도 낙상의 가능성을 증가시키는 요인이 될 수 있는 것으로 보여진다. 본 연구의 결과는 다중과업(multitasks)을 필요로 하는 보행 훈련 프로그램(gait training program)의 개발과 시행에 있어서 기초적인 자료를 제공할 수 있는 것으로 보여진다.

This study explores the relationships between the division of housework, perceived marital fairness, communication, and marital satisfaction in elderly households. Although the marital relationship is one of the most important factors affecting the quality of life, few studies have focused on marital quality, particularly in the context of older adults. Data were obtained from the 2nd National Korean Family Survey in 2010. The results based on a total of 410 elderly households with couples aged 60 and over indicate significant differences in housework participation between men and women. Women were responsible for most of the housework. According to the regression analysis, the division of housework, perceived marital fairness, and communication independently predicted marital satisfaction, but there were no significant relationships between sociodemographic factors and marital satisfaction. There were significant interactions between the division of housework, perceived marital fairness, and marital satisfaction through communication as a moderator of effects of the division of housework and perceived marital fairness on marital satisfaction. The higher the satisfaction with communication, the stronger the relationship between marital satisfaction and satisfaction with the division of housework was. On the other hand, the lower the satisfaction with communication, the greater the effect of perceived marital fairness on marital satisfaction was. These results suggest that the way in which elderly couples perceive their marital relationships and the level of their satisfaction in interacting with each other play important roles in enhancing their marital quality.

This paper aimed to study on the relevance of mental health and oral health. The subjects were recruited total 3,261 elderly of over 40 years old, using the Sixth Korea National Health and Nutrition Examination Survey(KNHANES). All the collected data were analyzed by chi-square test, t-test, and logistic regression using SPSS 23.0 version. Logistic regression was used to analyze the relationship of sleeping time or stress and the number of remaining teeth, and 95% confidence intervals were computed. Sleeping time odds ratio(OR) of the number of remaining teeth was 1.52 (95% confidence interval: 1.074-2.135) and Stress odds ratio(OR) was 2.39 (95% confidence interval: 1.855-3.090), but there is no statistically significant difference after adjusted age, gender and other variables.

Purpose: The purpose of this study was to examine the effects of Tai Chi exercise on flexibility, balance, walking ability, muscle strength, bone mineral density, and fracture risk in institutionalized elders. Method: A quasi-experimental pretest-posttest design with a nonequivalent comparison group was utilized, and 53 older adults living in one institution were recruited and assigned to one of two groups, experimental group (18) or comparison (20). Both groups completed posttest measures at 6 months. There was a 31% rate of dropouts. Tai Chi exercise was provided twice a week for 24 weeks. Outcome measurements were conducted by a physiotherapist at a university hospital health promotion center who did not know the group assignment. Results: At 6 months, the experimental group had significantly greater grip strength(t=2.12, p=.04), back muscle strength (t=2.42, p=.02), balance (t=5.31, p<001), and flexibility (t=3.57, p<.001). They also showed significantly greater bone mineral density of lumbar spine and femur, and reduced fracture risk. Conclusion: Tai Chi exercise was safely and effectively used with institutionalized elders for 6 months and significantly improved physical fitness, bone mineral density along with a reduction in fracture risk. Whether Tai Chi exercise would lead to prevention of fall episodes and fall related fractures in this population will require further study.

Physical activity has been effective in enhancing quality of life and physical fitness of older adults over relatively short periods of time. However, little is known about the Yoga-based exercise program on physiological changes and physical fitness with psychological variables in elderly women. The purpose of this study is to investigate the effect of Yoga- based exercise program on physiological, psychological factors and physical fitness in elderly women. Forty-four elders were recruited from the public health center. They were divided into exercise training group(n=22) and control group(n=22). The training group participating in 10 weeks of Yoga-based exercise program. Data was analyzed with descriptive statistics, the chi-square test, Fisher's Extract test, and ANCOVA to evaluate body fat, spine ROM, blood pressure, cholesterol, depression, life satisfaction, ADL and physical fitness. There was a significant improvement in blood pressure, total cholesterol, precent of body fat, physiological function, depression, life satisfaction, ADL and physical fitness in the exercise training group than that of the control group. From the results, Yoga-based interventions designed to improve various variables were equally acceptable to elderly women.

Purpose: The purpose of this study is to analyze the effect of Tai Chi exercise on Cardiorespiratory function and to identify directions for future research. Method: 19 articles from Medline search of english journals(1981-2004) and 2 from Korean nursing journals were surveyed. The contents analysis were focused on outcome measures and relative factors regarding cardiopulmonary function. Results: There are 21 articles including 8 articles with quasi experimental design, 7 articles with randomized controlled design and 6 articles with comparative non experimental research design. The major subjects of research were older adults, but hypertensive patients, cardiac rehabilitative patient, and osteoarthritic patient also included. The major style of Tai Chi was Yang style with 108-form. The duration of Tai Chi exercise was from 12weeks to 13.2 years in comparative non experimental studies, but 6 weeks to 16weeks in randomized controlled experimental studies. The most effective duration for cardiopulmonary function was over 16weeks. The variables for cardiopulmonary function were blood pressure, heart rate and cardiopulmonary function via $VO_2$ max(ml/kg/min). To reduce the blood pressure in the result was found in 2 articles, to reduce the heart beat was found in 1 article, to improve the cardiopulmonary function via $VO_2$ max in results were found in 7 articles(73%) among 11 articles. Conclusion: The Tai Chi exercise over 16weeks improves the cardiopulmonary function. It is suggested that to verify the effect of Tai Chi on cardiopulmonary function, the difference of gender, age, health status will be identified through repeated experiments.
