Background: This study aimed to examine the effectiveness of role-play in dental hygiene education by analyzing learners' perceptions and experiences of role-play classes. Methods: Role-play was used as a teaching method to run dental medical communication and practice classes for 31 3rd graders in the Department of Dental Hygiene to investigate the learner's perception of role-play classes, effectiveness of the classes, and learner's perception of the experience. The Mann-Whitney U test was used to analyze the differences in learners' perceptions of the role-play classes according to the main characteristics related to dental health communication education. Results: The correlation coefficient between awareness of dental communication education (4.74 ± 0.35) and awareness of role-play classes (4.44 ± 0.48) was an Rs of 0.634, showing a significant positive correlation (p<0.001). Conclusion: Learners recognized that dental hygiene communication competency is important for dental hygienists. In addition, a strategic teaching design is necessary to reduce the learner's burden on role-play considering the learner's experience, which is perceived as a disadvantage of role-play

The aging of Korean society is coming to the fore and its speed is unprecedented. Along with the volume rise in the population of the elderly, the rise of the elderly of means and high education stimulates the transition of our focus from "a desire of longevity" to "successful aging". The research objective is to classify groups by the different definitions of disability thinking of the geriatric oral health care. We targeted 34 aged people who live in Pusan Metropolis and analyzed the collected data and classified them into two types. The first type is the 'blunting of taste & oral pain' which is identified as a group. The second type is the 'blunting of taste & lowering quality of life' which is identified as a group. The common positive statements are 'There are some experiences to feel pain on and below tongue, cheek and upper palatine.', 'There are some experiences to feel unsatisfactory life'.

Purpose - This paper empirically studies the effects of advanced design innovation strategy on business performance, to investigate manufacturing industries that can develop design-driven-innovation strategies. Many researchers now recognize the importance of design in a CEO's decision-making process. To analyze these effects, this study deduces the definition of advanced design strategy by reviewing existing studies. The advanced design is a strategy that is applied to improve business performance instead of the appearance of a product for increasing its sales. In terms of business processes, the advanced design strategy is defined as the incorporation of business activities prior to the development of the product, to offer new experiences and values to users, from those designs. Research design/data/methodology - This paper establishes a model for empirical analysis. In this study, we derived factors of the characteristics of advanced design based on previous studies. We tried to investigate whether advanced design innovation strategy and entrepreneur's characteristics could have any impact on business performance. At the same time, we tried to find out the moderating effect of entrepreneurs' characteristics. The advanced design is made up of three elements: precedence, integration, and immersion of design activities. These three elements are independent variables for the model. The dependent variables are: increased rate of sales, R & D performance, and public image of the company. Specifically, this study establishes a CEO's characteristics as a moderating variable between the independent and dependent variables. Results - We proved that the level of entrepreneurs' characteristics has a moderating effect on the business performance. The findings of this study offer the following theoretical implications. The precedence of design activities positively affects the increased rate of sales by offering new experiences to users and creating new values. The integration of design activities also has a positive effect on the R&D performance. In addition, the immersion of design activities positively influences all the elements comprising business performance. The analysis of moderating variables elucidates that CEO's characteristics have a moderating role between precedence, integration, and immersion of design activities, and business performance. Conclusions - The practical implications of the study are as follows. This study contributes to the progression of advance design theories by conducting an empirical study on the advanced design concept. More importantly, the empirical study on the CEO group seeking exploratory innovation supports Verganti's "design-driven innovation" concept, according to which design can make innovation successful by offering useful values to users, as evident in the case of many innovative companies, such as Nintendo and Apple. Future studies need to investigate the reliability of practical examples, including the various activities of business. We suppose that there may be real differences between the results of this study and the applicative situation in the presence of a CEO group.

The purpose of this study is to empirically investigate the experiences and subjective opinions of urban agriculture in order to explore ways to vitalize urban agriculture. More specifically, we divides environmental value into three categories of ecology, landscape, and participation, and defines a function of urban agriculture to improve environmental values related to the three categories mentioned above. The main results of the empirical analysis using the survey data are summarized as follows. First, the probability of gathering information about urban agriculture is higher in metropolitan cities than small cities, and the larger the residence size, the higher the probability of actual urban agriculture participation. Second, the positive response rate was high for the three categories of urban agriculture, while the negative response rate was high for the surrounding environment. The implications derived from the analysis are as follows. First, the opposite results of experiences of urban agriculture suggests that local governments should further promote urban agriculture-based investment policies. In addition, these policies need to be preceded by analysis of the characteristics of population groups in the region Also, it is necessary to improve the environment through urban agriculture.

The purpose of the study is to explore the experiences and meaning of the AP (Advanced Placement) at the specialized school for the highly gifted through the in-depth interview with 39 college students who had graduated from the specialized schools with the AP experiences. It is expected that the AP will be expanded to the students at the Science High Schools from the year of 2015, however, there has been no study to examine the realities of the AP in-depth especially through the voices of the AP participants. Students have taken 8 required and/or selective courses as AP in average. Students usually start to take AP from the second year of the specialized school for the highly gifted, but some start from the first year through the placement test. Numbers of available AP courses vary by subjects, but relatively more courses open in the areas of math and physics. Students' opinions regarding the AP were quite positive. Specifically, the high quality of the AP class and energetic interaction between student and teacher compared to the college classes were preferred by the students. However, it was controversial whether C+ is enough for the pass condition of the AP. Students were using the shortened time by AP in diverse ways, such as early graduation, double majors, exchange students, individual researches, and so on. Most of all, they tried to search for their career interests through the AP experiences. In closing, the present study provides some advices and future directions for the better AP management, including the improvement of administrative system between schools for the gifted and the universities, and the expansion of the number of university which approves the AP system.

Science drama can be an useful tool for understanding the nature of science, Science-Technology-Society relationship by providing indirect experiences to young students. Specific science concept and knowledge can also be learned with high interests. In this study, to explore the usefulness of science drama in elementary science lessons, two scripts of science drama and lesson plans were developed and implemented. Six step model for science drama lessons was also suggested. One was 'Manhattan Project' which dealt with social, ethical responsibility in using science & technology (science argument drama), and the other was 'Mom, My blood type is O' which explained the heredity of blood type (science concept drama). Two teachers were asked to write their journals during preparation and implementation of science drama lessons, and the lessons were observed by the researcher and video taped for analysis. Some students were interviewed just after the lessons by the teacher and all students were asked to write their impressions, change of their thought, what is leant etc. Overall responses of students and teachers on the two science drama lessons were very positive, 'Mom, My blood type is O' got more positive responses, and girls were more positive than boys. Some students anticipated another science drama even suggest topics for it. 'Mom, My blood type is O' was successful in making students (grade 3) understand the knowledge related with heredity of blood type (71% of the students got perfect answer). In 'Manhattan Project' students (grade 5) perceived more diverse location of responsibility after the lesson, but the danger and harmfulness of atomic power was embossed. This implied the need of more careful planning for the relevant learning activities before and after the play of science drama.Two teachers perceived the science drama as a new, useful tool for some subject which is hard to deal with by other teaching method. They were also satisfied with students' high interest and engagement during the science drama lessons but the extra time and effort for the lessons were pointed out as a main difficulties.

Central sleep apnea (CSA) is characterized by respiratory failure of at least 10 seconds without any effort of the chest and abdomen in the absence of upper airway resistance during sleep. In this case, the patient experiences respiratory failure that does not meet the CSA diagnostic criteria and CSA symptoms. Magnetic resonance imaging diffusion-weighted imaging (MRI DWI) scans revealed a lateral medullary infarction. Continuous positive airway pressure (CPAP) was applied as a primary treatment for CSA and respiratory failure. During the titration of CPAP, the apnea-hypopnea index (AHI) and arousal index (AI) were worse than the results before its use (AHI: 42.5/hr→82.8/hr, AI: 21.7/hr→40.8h). As a result, adaptive servo-ventilation (ASV) was chosen as the secondary treatment. Compared to the night-polysomnography results before the ASV treatment, the AHI improved (42.5/hr→8.6/hr). Therefore, ASV is a potential treatment for CSA and respiratory failure in these patients.

The purpose of this study is to figure out the influence on the students' achievement of the cognitive and the affective domains by descriptive items assessment of teacher or peer and to obtain implications by analyzing the students' satisfaction and the reliability of the assessment. For this purpose, two classes of 11th grade students located in a small city were selected and took an exam related to the cognitive and the affective domains before and after the assessment. The assessment activities were carried out during 10 lessons and the teacher gave feedback to the students of the teacher assessment class in the lessons. In the peer assessment class, a small-size student group discussion and feedback were given to the students after the exam. The results show that higher level achievement group students represented relatively positive satisfaction on teacher assessment, and lower level achievement group students represented positive satisfaction on peer assessment. In spite of the same marker list, higher level achievement group students represent relatively high reliability than lower level achievement group students. The lower level achievement group students in the peer assessment class got statistically meaningful improvement of achievement than the students of teacher assessment class. The peer assessment activity was positively influenced on the affective domain of the lower level achievement group students, especially signigicant meaning of statistics was found on the students' perception about science.

This study was carried out to investigate the experiences of breast milk feeding information and education, breast milk feeding knowledge and attitude and needs for breast milk feeding nutrition education of high school students to encourage breast milk feeding. The subjects were 565 (male: 250, female: 315) high school students from first to third grade. The results obtained were as follows: In this survey, only 30.0% of subjects experienced breast milk feeding information and only 6.1% of subjects had breast milk feeding education. And the subjects showed the average scores of knowledge of breast milk feeding were 0.29 points of 1 point. Subjects knew well about ingredients of breast milk but they didn't know well about the physiology and method of breast milk feeding and benefits of breast milk feeding for mothers. The average scores of attitude of breast milk feeding were 3.03 points of 4 points, showed slight positive attitudes of breast milk feeding, but they had negative attitudes of emotional and practical aspects. The future plan of feeding practices was breast milk feeding 35.9% and 60.0% of formula milk feeding. A concern was that the students showed high ratio of formula milk feeding plan and they decided by incorrect knowledge of breast milk feeding. The 33.5% of students answered high school students will need breast milk feeding nutrition education, and they thought hospital faculties were the proper educators of breast milk feeding education, but dietitians were recomended as educators because of easy access at school and good knowledge of life-cycle nutrition. Therefore, to encourage breast milk feeding by mothers and supporters of breast milk feeding, breast milk feeding nutrition education is needed urgently among high school male and female students. And nutrition education programs will have to contain benefits of breast milk for babies and mothers and physiology and practical methods of breast milk feeding to improve emotional and practical attitudes for breast milk feeding. Nationwide campaign to promote breast milk feeding at public areas will be needed.

'Long-life' which has been the perennial interest to human beings also carries the risk of multiple losses such as the death of the family members and friends, the loss of physical and cognitive functions. In that regards, living a long life to be the 'oldest-old' could mean not only a 'symbol of successful aging' but also a hardship and low quality of life at the same time. Therefore, the issue of the quality of life of the oldest old has been the subject of the much of the public and research concern in recent days. While there has been increased awareness about the importance of the subjective aspects of the quality of life and meanings attached to the extended life, most researches on the quality of life of the oldest-old have focused only on the objective conditions of the quality of life such as health, economic status and housing conditions. To overcome these limitations this study aims to explore the subject meaning of 'living a long life' in Korean society by investigating centenarians and their caregivers' interpretations of aging experiences. Qualitative data were gathered from the forty-nine Korean centenarians and their caregivers through in-depth interview. Each interview was tape-recorded and transcribed verbatim. Researchers read each transcript a number of times to get some emerging themes. Most striking result was the fact that most of the centenarians express the 'guilty feelings' and try to offer the 'excuses' about their long life. This results were quite contrary to the results of the studies, done in Japan and western countries like Sweden, United States and Germany, where most of the oldest-old express quite positive interpretations about their long-life and take pride in their longevity. Lack of social support, cohort characteristics of the Korean oldest-old and the cultural interpretations linking the death of children to the long life of older generation are given as possible factors to these unique findings of Korean study. The policy implications of the results are discussed.
