In this study, we investigate the term-sets of 'base' or 'bottom': 'the bottom side of a polygon' and 'the base side (of a geometrical figure)'. And we study the concept of 'the base area' in the solid figures and the formula of 'the bottom dimensions'. We start from the 6th grade math problem: 'Find the bottom dimension of the rectangular.' The primary answer is that it does not use the term('the bottom dimensions') in the elementary mathematics. However, in the middle school mathematics, 'the base area' is used as means of 'the area of one bottom side', which is not explained anywhere from the elementary mathematics to middle school mathematics. In addition, the base is defined and 'the surface area' and 'the side area' is taught in the elementary mathematics, so we naturally think of 'the base area'. Therefore we first investigate the term-sets of 'base' or 'bottom' which has two elements: 'the bottom side of a polygon' and 'the base side (of a geometrical figure)'. Next we discuss 'the base area' through curriculum and textbooks, dictionary definitions and so on. In addition, we survey pre-service teachers and teachers about the solid figures and analyse the understanding of 'the base side' and 'the base area' comparatively. In particular, we compare the changes and the tendency of correct answers from the first question to the last question. As a result, we verify 'the cognitive gap' between the elementary mathematics and the middle school mathematics, we suggest the teaching of 'the base area' and succession subjects to teach figure domain in the elementary mathematics.

A study was designed to evaluate the level of moral development in 450 pre-dental professionals of 2 educational institution in Jeollabukdo, Ik san city. Data were collected through self-reported questionnaires from October 2010. The Korean version of the DIT(Defining Issues Test) was adopted to evaluate level of moral development with the score of P(%) and stage. The data were analyzed by descriptive statistics, t-test, one-way ANOVA and Pearson's correlation coefficient. The mean scores of P(%) was 43.10 in dental students and 41.21 in dental hygiene students(p=0.190). The score of stage 5A was highest which was followed by S3, S4, S6, S5B, S2. The score of stage 5B and 6 revealed sigificant difference by groups. The score of stage 6 revealed significant difference by sex in dental students(p=0.003). In dental hygiene students, it's significant difference by religion(S5B, p=0.044), birth order(S2, p=0.027) and growth area(S4, p=0.015). As for the correlations between moral development and the score of the stage, the score of P(%) was negatively correlated with the scores of stage 2, 3, 4 and 5B. On the other hand, the score of P(%) was positively correlated with the scores of stage 5A and 6. In conclusion, for enhancing dental students' moral development it is necessary a systemic ethics education and program development in curriculum.

In this paper, the teaching contents for angle and measure of an angle in elementary mathematics textbook between Korea and Japan were compared. From this comparison, the following five suggestions were presented as implications to improve the teaching contents for angle and measure of an angle in elementary mathematics textbook in Korea. First, it is necessary to reconsider the way of the definition of angle. There is no use of half line in elementary mathematics, except when to define angle, and the way to define angle and the way to define right angle are not consistent. Second, considering to associate the turning of plane geometrical figures to the $90^{\circ}$, $180^{\circ}$, $270^{\circ}$, $360^{\circ}$ is necessary, and associating them is connected to dealing with point-symmetrical shapes in the fifth grade. Third, there is a need to deal with "the measures of angles are same." in comparing angles. This is possible by superimposing two angles in comparing the measures of them. Fourthly, it is necessary to consider the introduction of the rotational angle. Dealing with the $360^{\circ}$ as the rotational angle is related to explaining that the sum of measures of interior angles in quadrangle is $360^{\circ}$. Fifth, it is necessary to be connected with middle school mathematics curriculum. The term 'straight angle' is used in middle school, and to obtain the sum of the measures of the interior angles of a regular polygon is the contents to be dealt with in middle school.

The purpose of this study was to determine the values of freshman nursing students and to determine changes each year over the four years of the study and to provide base data for curriculum and student guidance. The sample consisted of the freshman students who entered college of nursing from 1988 through 1991. The total sample was 358 students and data were collected during March of each of the four years. The data were analyzed using t-test, ANOVA and Pearson Correlation to examine the relationship between the subcategories of values and Duncan multiple range test to examine the relationship between the scores for each year and the demographic data. The instrument used in this study was the Survey of Personal Values and Interpersonal Values modified by UngYun Hwang and KyungHae Lee in accordance with L.V. Gordon's instrument. This tool provides scores on practical mindedness, achievement, variety, decisiveness, orderliness, goal orientation, support, conformity, recognition, independence, benevolence and leadership. The results of the study were as follows: 1. The nursing freshman students surveyed had the highest score for goal orientation (21.44) and the lowest for variety (17.13) on the SPY (Survey of Personal Values) and the highest score for benevolence (21.19) and lowest for leadership (17.00) on the SIV (Survey of Interpersonal Values]. In accordance with the standarized scores for Gordon's Spy for other' woman college students, the students in the study were between the 78% ile - 97 % ile and were in the 72 % ile 97%ile for the SlV. 2. When t-test scores were compared, no significant variation was found between the years for each of the values (P< .05). 3. A significant variation was found on variety, between 1989 and 1991 (P< .05), and between 1988 and 1991. The highest score was in 1991 in both comparisons. Supporting was also higher for 1991 than for 1988 (P< .05). 4. Religion and occupation of father did not show any significant differences (P< .05). There was no significant difference in values according to the student's religion or the occupation of their father. Students born in the metropolitan area had a higher score on variety than those from the rural area and vice versa on regulartiy (P< .05). The results of this study show that there is a higher score on values for'! University freshman than shown for freshmen in other universities reported from other research, To keep or promote values, it is very important that there be a systematic strategy of education and special educational programs.

Purpose: This study intends to set standard for organizing the curriculum of short-term dental technicians and the change of job environment, as well as the knowledge & training, by identifying the importance and actual job performance of dental technicians following job analysis in the university education of Dept. of Dental Laboratory Technology, and furthermore to foster junior executives to cope with modernization and globalization. Methods: The tools used in this study are based on the job analysis of research report suggested by National Health Personnel Licensing Examination Board(Lee Gyu-seon, 2011), and it consists of general characteristic 7 items. Every competence duty was measured through Likert 5 point gauging, and internal consistency through Cronbach's Alpha. The competence importance of entire questionnaire was .984 and its performance was .874, reflecting considerably high level, and in terms of each competence duty, high credibility was proved and high internal consistency was verified with competence importance ranging from the minimum .655 to the maximum .966 and its performance ranging from the minimum .677 to the maximum .993. Results: Competence importance and its performance in each duty on the job analysis of dental technicians were measured. In competence importance in each duty, the highest was "checking design order form"(average, 4.52), followed by "selling dental prosthesis"(average 4.49), "making removable orthodontic appliance"(average, 4.48), "open managing dental laboratory"(average, 4.46) in order. However, "making complete denture" was found the lowest(average, 4.23), with importance of all competence dutys was considerably high level. In the performance of its competence duty, "checking design order form"(average, 4.04) was found to be the most importance competence, followed by "making conservative restoration"(average, 4.00), "making porcelain"(average 3.98), "checking working cast"(average, 3.90) in order. However it was found out that "making fixed orthodontic appliance"(average, 3.12) was the lowest, and the importance of all competence dutys was quite high level. Conclusion: The duties of dental technicians consist of 13 kinds, in total, and it was found out that "checking design order form"(average, 4.52) was the most important in the competence importance and job performance. In particular, it was revealed that there was a great difference between the competence importance and its performance in the order of "selling dental prosthesis", "open managing dental laboratory", "making removable orthodontic appliance", "making CAD/CAM prosthesis", and then "making fixed orthodontic appliance".

This study is expected to be of significance in that it attempted to examine the personal information protection awareness of college students and the state of their personal information protection as prospective information processors and private information owners to boost their will to put private information protection in practice. As a result of making an analysis, the most common average time that the students spent in doing every online activity on weekdays was fewer than two or three hours, and the most dominant activities that they did over the Internet were for entertainment or hobbies. As for awareness of the nature of the Internet, they looked upon it as a quite open public space. Regarding the state of private information protection, they thought that changing passwords on a regular basis would be beneficial to personal information protection, and many thought that it's needed to withdraw from or shut down web sites that weren't used for a long time. In terms of actual practice, however, they didn't change their e-mail passwords regularly on the grounds that it's a hassle, and even the students who had experience of personal information leakage didn't report it or didn't ask for counsel on the grounds that they didn't want to be bothered as well. The majority of the students weren't cognizant of how to report or seek counsel. In the future, personal information protection should be educated on a continual basis as part of curriculum to raise awareness of it among students and boost their will to practice it with a sense of responsibility in an effort to prevent the occurrence of collateral damages triggered by personal information leakage.

This study aims to investigate the improvement in basic CPR quality on the basis of the hip joint angle of the rescuer among students in the Department of Emergency Medical Technology who completed a basic CPR curriculum. In this study, we carried out a comparative analysis using SimPad SkillReporter and Resusci Anne® QCPR® to measure the quality of CPR (depth of chest compressions, full relaxation, compression speed, and more) on the basis of the rescuer's hip joint angle in accordance with the 2015 AHA Guidelines and conducted chest compressions and CPR 5 times in a 30:2 ratio. It was found that maintenance of the rescuer's hip joint angle at 90 degrees while compressing and relaxing the chest made a statistically significant difference in both the experimental and control groups. Moreover, this indicated that the closer the hip joint angle was to 90 degrees, the better was the quality of basic CPR. However, there was no significant difference in the hip joint angle, degree of CPR, depth of chest compressions, chest compression speed, chest compression and relaxation percentages (%), accuracy of chest compressions, hands-off time during CPR, and percentage of chest compression time (p > 0.05). Maintaining the hip joint angle at 90 degrees for basic CPR was not significantly different from not maintaining this angle. Nonetheless, good results have been obtained at moderate depth and 100% recoil. Therefore, good outcome and high-quality CPR are expected.
