Purpose: This study is used to investigate the correlation among a stroke patient family's health, burden and quality of life. Method: Data was collected from one hundred twenty family care-givers registered at K and H Hospital in Seoul. Questionnaire data was drawn up by personal interviews aided by the staff nurses. The analyses of collected data are based on the rate of 100 percentage to the average, t-test, ANOVA, DMR, Pearson Correlation. Result: (1) The influential factors on physical health proved to be age, sex, academic career, matrimonial status, present occupation, economic situation, the relationship with the patient, the patient-caring term, and the family-formation. The psychological health issues were age, final academic career, matrimonial status, the relation with patient and the family-formation. Burdens were shown to be age, matrimonial status, the relation with patient, and the patient-caring term. The quality of life was determined by age, final academic career, matrimonial status, and the relationship with the patient, the patient- caring term, and the family-formation. (2) The rate of the physical condition was 2.87, the psychological condition 2.43, the sense of burden 3.08, and the quality of life was 2.42. (3) The rate of correlation between the burden and the quality of life was (r= -.547), the psychological health and the burden was (r= -.531), the physical health and the burden was (r= -.263), physical health and quality of life was (r= .301), psychological health, and quality of life was (r= .413). Conclusion: It follows from this study that there is a very close correlation among the stroke patient family's health, the burden, and quality of life. Therefore it is necessary that we should find various nursing intervention ways in order to mitigate the burden of family when caring for the stroke patients.

Sugarbeet cyst nematode (Heterodera schachtii) has recently been detected as a severe pest of Chinese cabbage fields in Korea. Two studies were performed to evaluate the effect of inoculation density of H. schachtii and plant age of Chinese cabbage on the final population of the nematodes. Chinese cabbage inoculated with high inoculation density (4 juveniles or eggs/g soil) showed significant differences in the number of cysts, females and eggs. The 40 day- old plants inoculated with high nematode densities yielded the highest nematode populations after 30 and 60 days of inoculation, compared with other plant age groups (0, 20, 30 day-old)used in the experiment. We, thus, summarize that, maximum nematode multiplication rates are made on comparatively older plants at the high nematode densities. Therefore, taking plant age into consideration at the transplanting of Chinese cabbage was recommended for the management of H. schachtii.

Objective : The purpose of this study is to report the effectiveness of a long-term Korean Medicine Treatment on 1035 atopic dermatitis patients Methods : Objective SCORAD Index(OSI) is used for measuring the degree of atopic dermatitis with photos of total 1035 atopic dermatitis patients who has visited oriental clinic from January 9, 2011 to October 31, 2013. Then, OSI was estimated according to gender, age, period of treatment and intensity. Results : 1. The ratio of male to female was 44.4 : 55.6. All patients were constituted with 26.5% of 0~11 year-old group, 15.7% of 12~18 year-old and 57.9% of 19 and more year-old. 2. The ratio of OSI improvement was significantly higher in women than in men after 3 month treatment, but there was no significant difference after 6, 9 and 12 months. 3. The OSI improvement of 0~11 year-old group was significantly higher than the other groups after 3 month treatment. But at the other periods of treatment, there was no significantly difference of the improvement among 3 different groups of age. 4. After 3, 6, 9 and 12 month treatment, the score of OSI was significantly lower than before treatment. After 12 month treatment, the score of OSI was lowest compared to the other periods of treatment. 5. The final OSI score of 87.7% patients was decreased compared to the initial. 6. All patients had been divided with 1.93% of the mild, 22.7% of the moderate and 75.4% of the severe by OSI intensity at initial visit. At final visit, the composition of patients was changed to 14.6% of the mild, 53.7% of the moderate and 31.7% of the severe. 7. The mild patients had got 42.56% of OSI improvement at the final. And the moderate had got 37.72% of OSI improvement at the final. 8. The severe patients had got 36.76% of OSI improvement at the final. And 89.2% of the severe had got decreased final OSI score compared to the initial. Conclusion : There was a definite decreasing of OSI score on the significant rate of Atopic dermatitis patients who had been treated by Korean medicine treatment at least for 3 months.

The purpose of the study was to investigate differences in self-esteem, appearance satisfaction, and clothing benefit pursuit among middle-aged consumer groups according to the gap between their subjective age and real age. For the study, the questionnaire was developed by the author and distributed to male and female consumers in their forties or fifties on september 1~10, 2014. A total of 470 questionnaires was collected and used for the final analysis. Data were analyzed by frequency analysis, reliability analysis, factor analysis, cluster analysis, ANOVA and Tukey's test, using the SPSS 18.0 Package Program. The findings were summarized as follows. The respondents were clustered in three groups including a group with younger subjective age than real age, a group with same subjective age group to real age, and a group with older subjective age group than real age, The younger subjective age group and same subjective age group showed greater self-esteem and appearance satisfaction than the other group. There were significant differences in four factors of clothing benefit pursuit including pursuit of fashion, pursuit of youth, pursuit of leisure, and pursuit of conformity among these three age groups. The younger subjective age group and same subjective age group showed greater importance on pursuit of fashion, pursuit of youth, and pursuit of leisure, whereas the older subjective age group did on pursuit of conformity.

The purpose of this study was to investigate effect of spectacle correction therapy instead of occlusion therapy for refractive amblyopia treatment. Spectacle correction were prescribed to give the same effect as a occlusion therapy by under correction for normal eye and there was no additional treatment but only spectacle correction for hyperopic amblyopia. The results can be summarized as follows: 1. In hyperopic amblyopia after correction, initial visual acuity($Mean{\pm}SD$) was $0.36{\pm}0.13$ and final visual acuity($Mean{\pm}SD$) was $0.82{\pm}0.23$. 2. Regardless with age, there was significant differences between initial acuity and final acuity, it shows improvement in visual acuity after spectacle correction treatment. 3. Initial correction age did not influence the length of treatment and success rate of treatment, so that ambyopia correction effect not related with age. 4. Compared with initial visual acuity with final visual acuity, initial visual acuity was in proportion to final visual acuity. 5. Incidence was higher in hyperopia and hyperopic astigmatism than myopia and myopic astigmatism in refractive amblyopia group and the therapy was more effective for hyperopia and hyperopic astigmatism than myopia and myopic astigmatism. 6. Treatment was effective even for children who is older than 8 years.

Objectives Amyloid β positron emission tomography (Aβ PET) is widely used as a diagnostic tool in patients who have symptoms of cognitive impairment, however, this diagnostic examination is too expensive. Thus, predicting the positivity of Aβ PET before patients undergo the examination is essential. We aimed to analyze clinical predictors of patients who underwent Aβ PET retrospectively, and to develop a predicting model of Aβ PET positivity. Methods 468 patients who underwent Aβ PET with cognitive impairment were recruited and their clinical indicators were analyzed retrospectively. We specified the primary outcome as Aβ PET positivity, and included variables such as age, sex, body mass index, diastolic blood pressure, systolic blood pressure, education, dementia family history, Mini Mental Status Examination (MMSE), Clinical Dementia Rating (CDR), Clinical Dementia Rating-Sum of Box (CDR-SB), hypertension (HTN), diabetes mellitus (DM) and presence of apolipoprotein E (ApoE) E4 as potential predictors. We developed three final models of amyloid positivity prediction for total subjects, mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia using a multivariate stepwise logistic regression analysis. Receiver operating characteristic (ROC) curve analysis was performed and the area under curve (AUC) value was calculated for the ROC curve. Results Aβ PET negative patients were 49.6% (n = 232), and Aβ PET positive patients were 50.4% (n = 236). In the final model of all subjects, older age, female sex, presence of ApoE E4 and lower MMSE are associated with Aβ PET positivity. The AUC value was 0.296. In the final model of MCI subjects (n = 244), older age and presence of ApoE E4 are associated with Aβ PET positivity. The AUC value was 0.725. In the final model of AD subjects (n = 173), lower MMSE scores, the presence of ApoE E4 and history of HTN are associated with Aβ PET positivity. The AUC value was 0.681. Conclusions The cerebral amyloid positivity model, which was based on commonly available clinical indicators, can be useful for prediction of amyloid PET positivity in MCI or AD patients.

Purpose: This study was to investigate the types of imaging modalities, analytical methods for age estimation, and the age of the subjects in research on age estimation using dental radiography through a scoping review, and to investigate the overall trends in age estimation studies. Materials and Methods: A scoping review was designed according to the Arksey and O'Malley guidelines and the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Three electronic databases were used as search sources (Medline, Embase, and Cochrane Library). Studies were classified according to the three main components of the research question. "What are the imaging modalities, analytical methods, and target age in dental imaging-based age estimation studies?" Result: The final 198 studies were selected by two reviewers. The most common imaging modality used in studies was panoramic radiography (69.7%), and studies using cone-beam computed tomography have increased over time. Analytical methods for age estimation were 62.6% in studies based on tooth development and 26.3% in studies using pulp/tooth ratio. The subject age was 27.8% for children and 27.3% for adults. Studies conducted in all age groups comprised the smallest category (5.2%). Conclusion: Panoramic radiography has been the most used types of imaging modalities for age estimation, and the most common analytical method was analysis of tooth development. Most studies targeted specific ages, and very few involved all age groups. Dental age estimation studies should be carried out with appropriate consideration of the imaging modality that is analyzed, the methods that are used, and the age that is targeted.

Purpose: The purpose of this study was to understand morality identity, occupational stress and authentic leadership and identify factors contributing to turnover intention among intensive care unit (ICU) nurses. Methods: Data were collected from 230 nurses at the university hospitals in Daegu, Ulsan and Busan between February 15 and March 23, 2017. Instruments measuring turnover intention, moral identity, occupational stress, and authentic leadership were utilized. Statistical analysis included t-test, ANOVA, Pearson correlational analysis, and hierarchical regression analysis. Results: A total of 207 nurses in ICU participated in this study. The power of explanation with age and dependents on turnover intention was 4.1%. With inclusion of occupational stress, moral identity, and authentic leadership factors put into the model, further 20.4% was explained. The explanatory power of the turnover intention in the final model was 23.6% (F=11.63 p<.001), and occupational stress was the key factor explaining turnover intention (${\beta}=.28$, p<.001). Predictive factors contributing to turnover intention were age, occupational stress, moral identity, and authentic leadership in final model. Conclusion: These findings demonstrated occupational stress, moral identity and authentic leadership as critical factors contributing turnover intention of ICU nurses. It is necessary to promote nursing manager's authentic leadership, and to encourage moral identity in ICU nurses. In addition, providing intervention programs to reduce occupational stress for ICU nurses is necessary.

Social capital theory provides a framework for analyzing the economic well-being. The purpose of this study is to analyze the age effect of social capital by comparing middle aged and the elderly, as well as to investigate the independent effects of social capital on their subjective economic well-being, respectively. The two concepts of "trust" and "social network" were used to measure the level of social capital. Comparisons between the age groups were made regarding the relationships between social capital and economic well-being of four age groups, including younger middle-aged, older middle-aged, younger elderly, and older elderly. Data from the $2^{nd}$ wave of the Korean Longitudinal Study of Ageing (KLoSA) were used. The final sample for this analysis is 8,406 respondents aged 45~84. The major findings are as follows. First, the level of social capital, trust and social network, is statistically different by age groups. Second, the model fits in the case of model including social capital variables are all larger than their counterparts in the four age groups. Third, social capital is "resource" that can contribute to increasing the subjective economic well-being. Based on the empirical results, implications for welfare policies related with issues of social security for the elderly in Korea are provided.

The purpose of this study is to ascertain the actual conditions of volunteering activities in respect to age-integrated leisure. This study is based on the 2010 Korea Leisure Life Survey. The participants in this study were 3015 people who reside in Korean cities, except for Jeju-do. Questionnaires from the 2010 Korea Leisure Life Survey were used for the final analysis. Data were analyzed through a descriptive analysis, Chi-Square test and ANOVA by SPSS WIN 17.0. The findings indicated that 18% of the participants participated in volunteer activities as leisure in the last one year. The major findings were as follows. First, demographic characteristics such as age, academic career, income, and marital status had a positive correlation with the degree of volunteer participation. Second, there were differences in duration and field of activities according to age. Third, though most of the non-volunteer reasons were 'lack of resources', there were different reasons based on age. In detail, the reason for 10-50 year-olds (economically active population) was 'lack of time', but the more than 60 year-olds was 'health concern'. Consequently, this access to the life cycle study shows the need to improve life satisfaction.
