Objectives: The objective of the study was to review the correlation between self-perceived oral health status and periodontal diseases in elderly Koreans, using data from the $6^{th}$ (2nd year) Korea National Health and Nutrition Examination Survey (2014). Methods: The subjects for this study were a total of 1,454 elderly people aged 65 years or older who responded to the health questionnaires of the $6^{th}$ (2nd year) Korea National Health and Nutrition Examination Survey conducted in 2014. Their general characteristics were analyzed using frequency analysis, while a cross-tabulation analysis (${\chi}^2-test$) was performed to understand the correlation with periodontal diseases. To clarify any effect of self-perceived oral health status on periodontal diseases, the selected variables were controlled and subsequently analyzed according to the logistic regression analysis. Results: In terms of the difference between elderly people with periodontal disease and those without periodontal disease, higher prevalence rates of periodontal diseases were found in women, those of younger age, those with lower educational and income levels, those with poorer subjective oral health status, those in the presence of chewing discomfort, those who had a toothbrushing frequency of twice per day, and/or those who had received no oral examination over the previous one year. Regarding the effect of self-perceived oral health status on periodontal diseases, 1.78-fold and 1.74-fold higher prevalence rates of periodontal diseases were shown with poorer subjective oral health status and in the presence of chewing discomfort, respectively. Conclusions: Based upon the results above, it is considered that a better understanding of self-perceived oral health status is necessary for a healthy life of the elderly. Furthermore, constant relevant studies and effective prevention programs intended to moderate the progress of or prevent periodontal diseases in the elderly in communities should be performed and implemented for the sake of better quality of life and oral health.

20 preservice teachers at college level participated in this study and interacted with students at elementary and middle school levels during science camp offered by science center in Taiwan. Preservice teachers displayed moderate (above the average, 4 point out of 5) understandings about scientific literacy and scientific views in all aspects of the nature of science before the camp. Then, the researchers designed science camp programs which were expected to promote students' scientific literacy; scientific knowledge, inquiry skills for experimentation as well as for argumentation, affective domain such as the attitude toward science and the understandings about nature of science and the relationship among STS (Science-Technology-Society), all of which were embedded in the programs. Preservice teachers seemed to perceive scientific literacy pretty well (over 4 point) before the camp, however, preservice teachers' understandings about scientific literacy were not much scored (around 3 point, but still moderate scores of average) as expected after concrete inquiry activities. The reasons why this happened could be that preservice teachers were not trained to employ theory into the context to be more practical or the researchers did not develop camp program which included the aspect of scientific literacy successfully. The discussion and implication were made in teacher education in that preservice teachers must be prepared how to bridge theory into practice, and informal science education in that educators at science centers must be trained to be experts in providing the envisioned educational programs to meet the goal of science education, scientific literacy.

PURPOSE: The law pertaining to medical service technologists does not discuss the scope and limits of doctors' guidelines. My paper aims to discuss these topics. METHODS: This study was based on a review of literature and an analysis of judicial precedents. RESULTS: Physical therapists have often noted the need for independent practitioners in their articles on health care. Their continued discussions on professional and educational differences have centered round this issue, but their ideas have not been accepted. Practitioners have continued to interpret doctors' guidelines in hospitals without discussing their scope. However, the Supreme Court presented a meaningful decision outlining the conceptual limits and the scope of medical practice. The court suggested, basing its interpretation in the goal of clarifying the concept of medical activities smoothly, was to follow a specific judgment on the levels of education, testing, and professionalism. CONCLUSION: The role of physical therapists is expanding in this country, in order to meet the needs of the ultra-aged society. Education is already responding to rising training needs. By dividing the doctors' guidelines into indirect and direct types, if there's no medical risk near or around the health center or hospital, it is a good idea to allow the management of physical therapy partially, while understanding the scope and limitations of these guidelines clearly. A teleological interpretation of the law is especially relevant, and can be implemented immediately by the authoritative interpretation on part of the health authorities without any legal amendments.

Background: This study was conducted to analyze the influence of socioeconomic characteristics of community on the food insecurity under the control of personal socioeconomic factors which may be influence to the food security. Methods: Food insecurity and individual socioeconomic characteristics were obtained from 2012 community health survey. Socioeconomic characteristics of communities were extracted from the data of Statistics Korea and local governments. Personal socioeconomic factors were sex, age, educational status, job, and monthly family income. Socioeconomic characteristics of communities were administrative district (urban vs. rural), senior population rate, degree of financial self reliance, degree of financial independence, portion of welfare budget, number of welfare facilities, and unemployment rate. We analysed the relationships between the food insecurity and socioeconomic characteristics of community using multi-level analysis under the control of personal characteristics. Results: On personal level age, sex, education status, and monthly family income were related with food insecurity. On community level administrative district (urban vs. rural), degree of financial independence, unemployment rate, and proportion of welfare budget among local general government accounts were related to individual food insecurity. Rural area, district with low levels of financial independence, low portion of welfare budget, and greater unemployment rate showed a higher level of food insecurity. Conclusion: To reduce the level of food insecurity in a community it is necessary to decrease the unemployment rate, in addition to providing support from the central government by increasing the proportion of the welfare budget so that both factors contribute to raising the degree of financial independence.

Background Phenomenography suggests that more variation is associated with wider ways of experiencing phenomena. In the discipline of mathematics, broadening the 'lived space' of mathematics learning might enhance students' ability to solve mathematics problems Aims The aim of the present study is to: 1. enhance secondary school students' capabilities for dealing with mathematical problems; and 2. examine if students' conception of mathematics can thereby be broadened. Sample 410 Secondary 1 students from ten schools participated in the study and the reference group consisted of 275 Secondary 1 students. Methods The students were provided with non-routine problems in their normal mathematics classes for one academic year. Their attitudes toward mathematics, their conceptions of mathematics, and their problem-solving performance were measured both at the beginning and at the end of the year. Results and conclusions Hierarchical regression analyses revealed that the problem-solving performance of students receiving non-routine problems improved more than that of other students, but the effect depended on the level of use of the non-routine problems and the academic standards of the students. Thus, use of non-routine mathematical problems that appropriately fits students' ability levels can induce changes in their lived space of mathematics learning and broaden their conceptions of mathematics and of mathematics learning.

The purpose of this study was to investigate factors associated with coping responses in Korean public high school students. Methods: This study employed a descriptive survey research design. The sample included 263 high school students who responded to a self-report questionnaire. Variables included socio-demographic characteristics, health-related characteristics, academic stress, somatization symptoms, social support, and coping responses. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlations, and multiple regressions. Results: Participants, regarding their school life, reported moderate levels of academic stress ($M{\pm}SD=2.3{\pm}0.52$) and somatization symptoms ($M{\pm}SD=2.3{\pm}0.71$), and a relatively high level of social support ($M{\pm}SD=4.2{\pm}0.67$). All the variables were associated with the use of multiple coping responses. Active-cognitive coping ($M{\pm}SD=2.9{\pm}0.68$) was most frequently used, followed by active-behavioral coping ($M{\pm}SD=2.5{\pm}0.56$). and avoidant coping ($M{\pm}SD=2.3{\pm}0.75$). Significant relationships were found among the measured variables: positive relation between academic stress and somatization symptoms, but, negative between academic stress and both somatization symptoms and social support. Students who had higher stress and more somatization symptoms were more likely to use avoidant coping than the others. In multiple regression analysis, while factors associated with each coping response differed, gender appeared to be a significant factor in all methods. Variables included in the final model explained 27% of the variance in avoidant coping (F=11.40, p<.001). Conclusion: Based on the study results, schools should provide tailored educational programs to help high school students reduce multisource stress and somatization symptoms at school and cope with them in more active and effective ways.

The purpose of this study was to measure dental hygienists' perception of the usefulness of clinical practice training. A total of 195 dental hygienists participated in the study. The findings of the study were analyzed according to age, the type of hospitals where respondents were working, experience in clinical practices and educational level as follows: 1. There were statistically significant differences in perception of the usefulness of the practice of amalgam filling preparation performed for dental operation among subjects at different ages (p<.01). 2. There were statistically significant differences in perception of the usefulness of the practice of paralleling technique(p<.001), the practice of amalgam filling preparation(p<.01) and the practice of trauma treatment preparation(p<.05) among subjects working at different clinics 3. Significant differences were observed in perception of the usefulness of the practice of sterilization(p<.05), the practice of suction(p<.05), the practice of history taking preparation (p<.01) and the practice of halitosis patient management preparation(p<.05) among subjects with different years of experience in clinical practices. 4. Significant differences were found in perception of the usefulness of the practice of paralleling technique among subjects with different education levels. The findings of the study suggest the need for strengthening education programs for clinical training content and practices which subjects considered important for their job. At the same time, the study emphasizes the need for developing training programs designed to produce dental hygiene preceptor who can provide dental hygienists with practical clinical training in cooperation with college and dental clinics.

다양한 수준에 있는 학생 모두에게 일정 정도의 수학을 가르치기 위해서 제7차 교육과정부터 우리나라에서는 수준별 수업을 교육과정에서 권장하고 있다. 주로 사용되는 수준별 수업 방식은 학생들을 그 수준에 따라 두 세 그룹으로 분리한 후 각 수준에 맞는 별도의 활동과 과제를 제시하는 것이다. 본 연구에서는 이런 분리된 수준별 수업을 개선하기 위하여 여러 수준의 학생들을 통합하여 지도하는 방안을 모색하고자 하였다. 영재아를 지도하거나 창의성을 신장하기 위한 수학 수업과 관련해서만 열린 문제에 관한 연구가 이루어져왔다. 그러나 본 연구는 보통의 수학 교실에서 열린 문제는 다양한 수준의 학생들도 반응을 보일 수 있고, 이러한 다양한 반응을 교사가 통합할 수 있다면 낮은 수준의 학생이 잠재적 발달수준으로 수준 상승이 이루어지도록 도울 수 있다는 논의를 바탕으로 열린 문제와 병행 과제를 활용하는 방안을 생각하여 보았다.
