This study analysed the income-related health inequality of the aged in Korea applied to EQ-5D. Two decompositions were used in analysis. One was the decomposition of income-related health inequality into six different dimensions of EQ-5D, and the other was to decompose it by sub-group such as sex, region, existence of spouse. The results are summarized as follows. First, the health concentration index(CI) of the aged was .0254, which meant that there were pro-rich inequality in elderly people's health levels. The same patterns were also seen in the analysis of different dimensions of EQ-5D such as mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Second, mobility accounted for 35.8% of total EQ-5D score, most contributing to CI of the dimensions of EQ-5D. The CIs by the dimensions ranged from .0091 for mobility to .0013 for self-care. Third, The decompositions by sub-groups showed that the contributions of sex, region, and existence of spouse to health inequality was similar to each other, all of three sub-groups accounted for 10 % of inequality respectively. Fourth, the inequality within group was higher in female group, rural area, and the aged without spouse. The average health level of these groups was lower than that of the other ones, too. These facts indicated that old women, the aged without spouse, and the elderly in rural area were the most vulnerable groups in health problems. Therefore, it is necessary to pay more attention to health problems of these groups in the policy making of health security and social welfare services.

In order to find out whether the traditional mass media in our society are sufficiently functioning as a vehicle of providing scientific information to the public outside the school education, public perception of science articles in mass media and scientific terms used in high frequency in science articles have been examined. To investigate the public perception on science articles, a questionnaire was constructed about the usefulness, importance, access frequency, and understanding of science articles. The questionnaires were conducted in areas with high flow populations such as train stations or subway stations. A total of 425 responses were used for analysis. In order to extract high frequency scientific terms used in science articles, two television companies and two newspapers were designated as target media, and their texts on science articles reported over the last 17 years were collected to investigate the frequency of scientific terms used. Based on the frequency, we conducted the self-report comprehension test for the top 100 scientific terms. The results of this study show that the public in our society has relatively high perception of the importance and usefulness of science articles, however, reading and understanding the articles seems to be somewhat difficult. In addition, the scientific terminology used in science articles has a high degree of comprehension for those of higher education, natural sciences majors, and men. In addition, scientific terms with high understanding degree were characterized according to gender, age, educational background, and field of major.

공공수역 수질오염 관리에 있어 비점오염원 관리의 중요성이 크게 부각되고 있다. 새만금호 유역은 농경지비율이 40%로서 넓기 때문에 농업비점오염 관리가 중요하다. 농업비점오염 저감을 위한 기법 연구는 국내에서 그 간 상당 수준으로 진행되었지만, 그 기법을 실행할 주체인 농업인이나 지역주민의 역량이나 농업비점오염의 인지도에 대한 연구는 부족한 실정이다. 본 연구는 새만금유역에서 농업비점오염과 관련된 주체들 간의 정보의 소통과 흐름에 대하여 분석해보고, 또한 농업오염 교육 전후에 있어서 지역주민과 농업인의 농업비점오염에 대한 인식도와 교육효과에 대해서 살펴보았다. 먼저, 농업비점오염과 관련된 주체들 간의 지식흐름은 매크로레벨 즉, 정책입안자, 전문가 레벨에서 관련정보가 정체되어 있었고, 실제 농업비점오염 관련 저감 기법이나 정책을 실행하는 주체인 마이크로레벨의 농업인과 지역주민, 이를 지원하는 시군 공무원, 지역전문가 등 매소레벨을 지원하기 위한 정보로 가공 전달되지 못하고 있었다. 농업부서와 환경부서 사이의 농업비점오염에 대한 인식도의 차이가 크게 나타났으며, 특정 분야를 중심으로 활발한 소통이 있는 반면, 정보의 의도적 차단, 자기조직의 대응을 위한 형식적, 임시적 소통이 이루어지고 있었다. 귀농인과 친환경농업인에 대한 교육을 통하여 농업비점오염에 대한 인식도는 교육 전 38.1%에서 교육 후 100%로, 교육 후 농업비점이 오염원이라는 인식도도 친환경농업인 91%, 귀농귀촌인 78%로 응답하였다. 농업비점오염원 관리가 수질개선에 미치는 효과에 대하여는 친환경농업인은 5점 만점에 3.67점, 귀농귀촌인은 4.05점, 농업비점오염원 관리가 필요한지에 대하여 친환경농업인은 4.05점, 귀농귀촌인은 4.09점으로 두 집단 모두 농업비점오염원 관리가 필요하다고 응답하였다. 반면, 친환경 농업은 저감기법의 오염 저감 효과는 높게 인식하였지만, 직접 실행해 볼 의사는 3.4점, 저감 기법을 주위에 소개나 권고할 의사는 3.5점이었다. 또한, 실행 가능한 저감 기법으로는 퇴액비 사용, 완효성 비료사용, 녹비작물재배 등의 순이었다. 저감기법이 어렵다고 응답한 이유는 복잡할거 같다, 귀잖을 것 같다, 추가비용으로 손해, 저감효과 신뢰성 부족, 농업은 오염원이 아니다 등으로 나타났다. 이상의 연구결과를 살펴볼 때, 주체들 간의 정보와 지식흐름을 이어줄 중간조직의 필요성과 농업인의 인식의 변화가 행동의 변화로 이어질 수 있는 교육?홍보 기법과 농업인의 수용성이 높은 저감기법의 개발과 보급이 필요함을 시사하였다.

In this study, the effect of user characteristics and technical characteristics of a blockchain-based financial platform on the intention to use of financial consumers was analyzed. Also, in this influence relationship, we analyzed what kind of causal relationship between relative advantage and perceived risk on intention to use. From June 1 to July 30, 2021, a non-face-to-face self-filling online survey was conducted with a sample of subjects who had experience using a financial platform grafted with blockchain technology, and the study was conducted in 187 copies. For statistical processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis and 3-step mediated regression analysis were performed using SPSS 21.0 program. The significance level of the statistical value was set to less than 95%. The research results are as follows. First, it was found that innovativeness and usefulness affect the intention to use in the user characteristics. Second, in the technical characteristics, compatibility and reliability were found to affect the intention to use. Third, it was found that relative advantage and perceived risk play a partial mediating role in the relationship between user characteristics and intention to use. Fourth, it was found that relative advantage and perceived risk play a partial mediating role in the relationship between technical characteristics and intention to use. Fifth, it was found that there were differences in the ubiquity of user characteristics, compatibility of technical characteristics and intention to use according to the experience of using the certificate. The results of this study can contribute to the development of a financial platform based on the Internet of Things.

The main purpose of this study was to examine the satisfaction of online classes of undergraduates who have experienced sudden online classes in college because of COVID-19, and to analyze the differences of the satisfaction of online classes depending on colleges. The participants were 1,380 college students. Descriptive statistics, one-way ANOVA, and Post-hoc Scheffé were performed. Undergraduates were highly satisfied with online classes in cultural subjects and major subjects, whereas they showed low satisfaction with appropriateness of the assignment. There were statistically significant differences in online class satisfaction between colleges. Students at the College of Education were highly satisfied with online classes satisfaction, while engineering students were less satisfied with online classes satisfaction. There were statistically significant differences in students engagements between colleges. Regardless of colleges, students displayed low satisfaction in e-class server and teaching and learning infrastructure. These findings suggest that we need to provide autonomous support and make an effective online learning environment such as server expansion and e-class improvement to enhance undergraduates' self-directed learning. We also should come up with effective online classes guidelines.

The purpose of this study was to explore perception about shared decision making of family caregivers of patients with early dementia (PWED). This study was conducted with a sample of 12 family caregivers (mean age = $71.4{\pm}10.4$) of PWED from three dementia safety centers in Seoul. In-depth interviews were done for each participant about shared decision making and data were analyzed using qualitative content analysis. Six categories and 17 sub-categories identified for participants' perception about shared decision making: means to facilitate communication with patients with dementia, means to secure autonomy of patients, opportunity to facilitate treatment, cause of increasing family caregivers' burden, cause of worsening relationship with patients, and option for choices depending on priority change. The findings of this study can provide a knowledge basis for health care professionals and policy makers to understand how family caregivers of PWED think about shared decision making. It would be of great value to develop educational programs and practical guidelines about shared decision making for PWED and their family, which may contribute to respecting PWED's self-determination right as well as reducing burden of their family.

Study Design: Case report. Objectives: We report a case of pure epidural cavernous hemangioma located at the thoracolumbar spine in a 53-year-old woman that mimicked a neurogenic tumor on magnetic resonance imaging (MRI). Summary of Literature Review: A pure spinal epidural cavernous hemangioma without bony involvement is a very rare lesion about which limited information is available in the literature. Materials and Methods: A 53-year-old woman visited our clinic for hypoesthesia with a tingling sensation in the left anterolateral thigh that had begun a month ago. No other neurologic symptoms or signs were present upon a neurologic examination. MRI from an outside hospital showed a $2.0{\times}0.5cm$ elongated mass at the T11-12 left neural foramen. The tumor was completely removed in piecemeal fashion. Results: The histopathologic examination revealed a cavernous hemangioma, which was the final diagnosis. The outcome was favorable in that only operation-related mild back pain remained, without any neurologic deficits, after a postoperative follow-up of 2 years and 3 months. No recurrence was observed on MRI at 2 years postoperatively. Conclusion: Pure epidural spinal cavernous hemangioma is very rare, and it is very difficult to differentiate from other epidural lesions. However, we believe that it should be included in the differential diagnosis of spinal epidural tumors due to its favorable prognosis.

The purposes of this study are to identify the latent classes of school violence depending on bullying and victimized experience by type and the influences of individual-level and school-level variables on determining these latent profiles. For these research goals, the present study utilized data from the Seoul Education Longitudinal Study(SELS) 5th wave, containing data from 2,195 middle school students who experienced school violences more than once. Multilevel latent profile models were applied to examine school violence among students. Our results indicated that there were four latent classes; high-level bullying and victimized group (1.7%), mainly bullying group(2.1%), mainly victimized group(3.7%), verbal bullying and victimized group(92.5%). Gender, resilience, self-control, peer relationship, parental relationship were significant determinants of the latent profiles at student level. Teacher-student relationships, school violence prevention, gender ratio of school were significant determinants of the latent profiles at school level. The present study contributed to extending theoretical discussions by classifying students into groups based on frequency and different forms of bullying and victimization. Moreover, this study examined determinants of student and school level simultaneously by dealing with multilevel data.

This study attempted to identify factors work environment that affect job satisfaction in dental hygienists. This study was conducted between August 29 and September 28, 2017, as part of an in-depth study of the 'Survey on the Working Environment of Clinical Dental Hygienists' of the Korean Dental Hygienists Association. To get the responses, the questionnaire was posted on the website of the Korean Dental Hygienists Association, and of the respondents, 4,663 were selected and analyzed. An independent t-test and one way ANOVA analysis were used to make a comparison of job satisfaction according to the general characteristics, salary, and tasks. Logistic regression analysis was conducted to identify factors affecting job satisfaction. The significance level was 0.05. In regard to salary information, the job satisfaction was found to be high (p<0.001) in cases where the salary was considered appropriate, when incentives were provided, when rewards or vacation expenses were supported, and when overtime and nightly work allowances were paid. In regard to job information, the job satisfaction was found to be high (p<0.001) when the volume of work was considered appropriate, when there were sufficient numbers in the workforce, and when the division of labor among the other personnel was clear. As a factor affecting job satisfaction of dental hygienists, the case of thinking that 'workload is appropriate' was found to be 2.052 times, showing the highest score. Job satisfaction in dental hygienists affects the turnover and has a significant effect on the performance of the organization. Therefore, it is believed, that it is urgent to improve the working environment such as salary and clear division of duties affecting job satisfaction of dental hygienists.

The purpose of this study was to clarify whether or not alcohol drinking patterns are associated with sleep quality. A cross-sectional study was carried out by self-administered questionnaire in May, 2017 among 553 male workers who employed in manufacturing industries in D city. Logistic regression analysis was used to evaluate whether or not alcohol drinking patterns (as measured by frequency, amount of alcohol per day, and amount of alcohol per week) were associated with poor sleep quality (as measured by Pittsburgh Sleep Quality Index). As a result, in comparison with male workers who did not drink, the adjusted odds ratio for poor sleep quality was 0.44 (95% CI=0.232-0.845) for those who drank alcohol once a week or more, 0.31 (95% CI=0.192-0.829) for those who drank less than 1 glass daily, and 0.28 (95% CI=0.167-0.762) for those who drank 1-3 glasses daily. The results of this study suggest that some alcohol drinking patterns may affect sleep quality among male workers.
