The spontaneous frequency of genetic damage and the possible relationship of this damage to dietary and nutritional variables were investigated in peripheral blood lymphocytes from 45 elderly people using sister chromatid exchange (SCE). The relationship of dietary and nutritional factors on SCE was assessed by different degrees of smoking status such as smokers (n=14), ex-smokers (n=16) and non-smokers (n=15). Significant relationship of the SCE frequency to nutrient intake of the combined subjects (n=45) was found. When cigarette smoking status was taken into account, there were negative linear relationships between SCE and fat, phosphorus or vitamin A intakes of the non-smokers as well as SCE and the dietary quality scores. There was a positive linear relationship between SCE and food frequency of meat and fish among the smokers. Use of artificial sweetners in ex-smokers of the elderly people produced a significant increase of SCE in comparison with the mean SCE for those not using sweetners. Other dietary parameters, including intake of coffee, green tea and ginseng tea, alcohol consumption, use of processed foods, and administration of vitamin pills did not show any correlation with SCE. These results suggested that dietary fat, phosphorus or vitamin A status are the major determinants of spontaneous DNA damage in lymphocytes of the elderly people.

The purpose of this study was to investigate the perceived difficulties during both pre-treatment period and admission period for radioactive iodine therapy (RAIT), the level of information about RAIT provided by medical staffs and the satisfaction of RAIT process in thyroid cancer patients receiving RAIT. Participants were 165 thyroid cancer patients, who had total thyroidectomy and had been offered RAIT. The data were collected using structured questionnaire and open-ended questions and analyzed by descriptive statistics and content analysis. The most frequent perceived difficulties of RAIT was associated with thyroid specific symptoms during both pre-RAIT period and RAIT admission period(38.2% vs 43.0%). The rating of RAIT information provided by medical staffs was evaluated as over moderate level(mean $3.63{\pm}0.80$). The RAIT process satisfaction was investigated as moderate level(mean $6.43{\pm}2.21$). the satisfaction of RAIT was the highest in medical attention and coping procedure (mean $7.64{\pm}2.37$) however it was the lowest in adequacy of RAIT information(mean $5.67{\pm}2.78$). Thus the nursing intervention program for thyroid cancer patient undergoing RAIT should be developed to support needs of thyroid cancer patients related to thyroid specific symptoms and to improve patients' understanding about RAIT procedure so that patients have competence to participate in therapeutic activities efficiently.

The purpose of this study was to exam nursing students to verify the effects of self-directed learning readiness, teacher-student interaction, educational performance, stress and learner motivation on learner satisfaction. The study population consisted of second and third year nursing students at E university located in S city. Data were collected between June 15, 2016 to June 24, 2016, and questionnaire comprised items to measure general characteristics, learner motivation, teacher-student interaction, self-directed learning readiness, educational performance, and learner satisfaction. A total of 132 students were included for the final analysis. Learner satisfaction was positively correlated with self-directed learning readiness (r= .21, p= .018), teacher-student interaction (r= .39, p<.001), educational performance (r= .21, p= .014), and learner motivation (r= .75, p<.001). In addition, learner motivation was positively correlated with self-directed learning readiness (r= .24, p= .005), teacher-student interaction (r= .38, p <.001), and educational performance (r= .21, p= .018). Finally, learner motivation and teacher-student interaction were found to explain 59.7% of the variance of learner satisfaction. Our findings suggest strategies and interventions that boost learner motivation and teacher-student interaction which are required to improve learner satisfaction in nursing education.

This study was conducted to examine musculoskeletal disorder and analyze the effects of musculoskeletal pain control and self-efficacy on musculoskeletal disorders in dental hygienists. Material and Methods; 483 dental hygienists residing in Gwangju were collected by the convenience sampling method and the self-administered questionnaire survey was conducted. Frequency analysis, crosstab analysis, t-test, and multiple logistic regression analysis were used for analysis. Results: the prevalence of musculoskeletal pain among subjects was 83.9% for the prior year, with 29.8% of patients being afflicted by musculoskeletal disorders. The factors influencing musculoskeletal disorders were musculoskeletal pain resolution. For pain resolution, the odds ratio of musculoskeletal disorders of the group who answered treatment in a hospital, an Oriental medicine clinic, or a pharmacy was 0.22 (95% confidence interval, 0.14-0.34) compared with the group who answered sick leave or task change, suggesting a negative relationship. These findings indicate that people with musculoskeletal disorders were not treated in the hospital, Oriental medicine clinic, or pharmacy. Therefore, it is necessary to improve medical management (oriental medicine, intravenous injection or medication, heat therapy or cryotherapy, steroid treatment, counseling, endovascular treatment using spinal cord stimulation, physical therapy, stretching, rehabilitation, and manual therapy) and job environment and to make a good approach to the prevention of musculoskeletal disorders to control dental hygienists' musculoskeletal pain.

This study was conducted to identify the effects of baby care using dolls on nursing students' major satisfaction, class satisfaction, and knowledge of newborn care. A quasi-experimental nonequivalent control group, pretest-posttest design was used. The subjects of the study were 95 nursing college students who agreed to participate. The control group (n=47) received lecture education consisting of watching newborn videos while the experimental group (n=48) received a practical education involving caring for a doll resembling an infant. Data were collected from March to May, 2019 and analyzed using descriptive statistics, χ²-tests, and t-tests with the SPSS/WIN 21.0 program. The major satisfaction score of the experimental group was higher than that of the control group, but it was not statistically significant (t=1.64, p=.107). The score for class satisfaction differed significantly between the experimental group and control group (t=2.08, p=.043). The knowledge of newborn care score for the experimental group was higher than that for the control group, and there was a statistically significant difference (t=-5.82, p<.001). Overall, the results show that baby care using a doll has positive effects on class satisfaction and knowledge of newborn care. In the future, it will be necessary to develop and apply effective teaching methods in line with the times.

Objectives : Though gastric cancer is one of the most common cancer in Korea, there have been few studies to explore psychological distress in gastric cancer. The purpose of this study was to investigate the prevalence and associated risk factors of psychological distress among patients with gastric cancer. Methods : With consecutive sampling, a total of 274 patients with gastric cancer who admitted to a cancer center in a general hospital were recruited and assessed on psychological distress using the Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer-related clinical variables were also evaluated. Results : One hundred fifty-three(55.8%) patients with gastric cancer showed psychological distress. Logistic regression models revealed that having alcohol drinking experience[odds ratio(OR)=2.10, p=0,034] and low performance status(OR=2.40 p=0.002) were significantly associated with psychological distress in patients with gastric cancer. Conclusions : These findings indicate that approximately half of patients with gastric cancer suffered from psychological distress and having alcohol drinking experience and low performance status would be associated risk factors, suggesting the need for distress screening and psychosocial supportive care in patients with gastric cancer.

Objectives : Insomnia may be one of the risk factor for suicidal ideation, but little is known about the mechanism by which sleep disturbances confer risk for suicide. The aim of this study was to investigate examine whether insomnia severity would be associated with resilience and suicidal ideation, and whether resilience would mediate the relationship between insomnia and suicidal ideation. Methods : A total of 432 community-dwelling adults(227 male, 205 female,) completed the self-report questionnaire that covered basic socio-demographic data. To assess the psychological variables, the following instruments were applied: Insomnia Severity Index(ISI), Korean Version of the Connor-Davidson Resilience Scale(K-CD-RISC), Beck Hopelessness Scale(BHOP) and Scale for Suicidal Ideation(SSI-Beck). People with an ISI score of 8 or higher were defined as insomnia. Results : Greater insomnia symptom severity was significantly associated with higher level of suicidal ideation and lower level of resilience, adjusting for hopelessness, age, sex, presence of family members living together, and household income. Additional analysis revealed that disturbance of sleep initiation and disturbance of sleep maintenance were significantly associated with suicidal ideation. Mediation analyses revealed that resilience significantly accounted for the relationship between insomnia symptom severity and suicidal ideation. Conclusions : These findings suggest that the evaluation and control of insomnia and resilience may be needed to reduce the risk of suicide.

Korean tourist areas are designated/managed in accordance with the Tourism Promotion Act. Since Taejongdae was designated as a tourist area in 1969, a total of 230 tourist areas have been designated/built/operated. It has been 46 years since the first tourist area was designated. According to the Tourism Area Life Cycle by Butler, it is estimated that the flow of the life cycle will be reflected in ups and downs over time. Thus, this study aimed to provide basic data for suggesting the direction of changes and development of the future tourist areas after analyzing the life cycle stage of domestic tourist areas, by applying the Tourism Area Life Cycle by Butler. The research method was based on the tourist areas by year, the number of visitors, and data of the target to derive the change transition curve, obtained by dividing the life cycle stages of the tourist areas based on the visitor rate of change. In the analysis results, more than 1/3 of domestic tourist areas are reaching the stagnation/decline stage, and tourist areas such as hot springs and seaside/beach resources show a particularly high ratio of stagnation/decline. The tourist areas that already have reached the stagnation/decline stage will need to analyze the causes for the decline, seek for resolution measures, and introduce new innovative elements. Even though the results of this study are not sufficient to be used as an absolute standard to decide the life cycle stage of domestic tourist areas, it is considered to be adequate for phenomenologically understanding the life cycle stage of Korean tourist areas. Based on this study, the causes for the stagnation/decline of tourist areas can be revealed while it can be also used as basic research to establish revitalization measures for tourist areas by introducing new innovation.

The purpose of this study is to investigate teachers' responsive practices in whole class discussion after small group argumentation and the underlying epistemological framing. Three teachers and 84 students participated in this study by engaging in argumentation activities about the sensory system. We recorded both their discussions in the classes and our interviews with the teachers, which were transcribed for analysis. The results of the analysis showed that the teachers' responsive practices and the epistemological framing were categorized into four types. By framing the discussion as 'reaching the correct answer through discussion,' the teacher focused on whether students' ideas corresponded to scientific concepts and transferred scientific ideas to the students. By framing the discussion as 'eliciting appropriate conceptual resources and developing them into a scientific idea through critical evaluation,' the teacher engaged in the students' discussion as another participant, and considered the small groups' arguments as resources that could develop into scientific concepts. By framing the discussion as 'sharing small groups' arguments,' the teacher responded by asking for clarification of each group's argument, considering it as a valid argument in its own way. By framing the discussion as 'reaching a consented argument through critical evaluation,' the teacher negotiated students' critical evaluation and revision of the arguments. We explored the implications and limitations of each type of responsive practice and considered that the results of this study will contribute to developing teachers' responsive teaching strategies in argumentation activities.
