The purpose of this study was to investigate changes in geological contents knowledge and self-confidence before and after the geological field trips. Fifty seven undergraduate students at a national university of education participated in this study. The questionnaires were developed by the researcher to serve the purpose. Findings were as follows. First, before and after the geological field trip, there was no significant difference in changes of geological content knowledge (p<.05). However, participants' self-confidence about the geological field trip changed significantly (p<.01). Second, there were no significant differences in changes of both variables in terms of gender (p<.05). And in this study, participants were grouped into two: science track that selected science areas and non-science track with social study selected in the college scholastic ability test. There were also no significant differences in changes of geological contents knowledge and self-confidence in terms of science or non-science track (p<.05). Third, in terms of the geological content knowledge, 24 pre-service teachers showed an increase, 12 students unchanged, and the 21 participants decreased. In contrast, per participants' self-confidence about the geological field trip, fifty three students indicated an increase with only one participant unchanged, and three preservice teachers decreased on the score. Finally, after the geological field trip, participants' comments indicated that they could feel the mystery of nature with the mind of a great experience. As a result, data showed that pre-service teachers became interested in geology, and motivated more in learning geological area than ever.

Objective: The purpose of this study was to get the cognitive reaction time according to the intensity of auditory stimuli in older people and to differentiate the cognitive reaction time between older people and adults. Method: 49 subjects consisted of 32 older people and 17 adults. Cognitive reaction time was assessed with Simple Auditory Reaction of Foundation I in PSS CogReHab. Analysis of the data was done by using independent t-test. Results: The results were as follows: 1. There was a significant difference of the mean of cognitive reaction time to the intensity of auditory stimuli. 2. There was no significant difference from older people regardless of sexual distinction in mean of cognitive reaction time. However, there was a significant difference of the mean of cognitive reaction time in adults. 3. There was a significant difference between older people who got a job or not in 90 dB of auditory stimuli. 4. The mean of cognitive reaction time to the intensity of auditory stimuli in older people was slower than adults. There was a significant difference of the mean of cognitive reaction time between older people and adults in 70 dB of auditory stimuli. 5. The mean of cognitive reaction time to the intensity of auditory stimuli in older people did not have the significant difference in scholastic ability. Conclusions: The results of the study showed slowing of the cognitive reaction time in auditory stimuli to aging in older people. Therefore, applying silver industry and development of equipment for older people may maintain independent life.

This study was conducted using the phenomenological research method to collect and analyze high school students' opinions about fusing "science" textbook that reflect the 2009 Revised Curriculum. Ninety six students were chosen to be participants from 32 high schools that selected by city and province. The data collection was carried by individual interviews and group discussions. The results are as follow; students' opinions were summarized to 50 themes, and then classified to 9 theme clusters and 2 categories. Students' opinions were divided into a positive position - "it is good because interesting material associated with life", "the structure of textbook is good", "teachers' efforts make class interesting", and "it will help in career choices"- and negative position - "the content is difficult to understand", "the configuration is complex", "I have less interest about it because it doesn't related College Scholastic Ability Test", "teacher's explanation is insufficient", and "it is not associated with career choice"-. The living-related material and story-telling configuration received good reviews from students. On the other hand, the configuration of topics makes many concepts to use, so students have difficulty understanding the content and pointed out the lack of teachers' explanations about unfamiliar areas. In order to solve the difficulties, variety teaching material for fusing "science" will be developed.

Purpose: This study was performed to identify the effect of admission type on college adaptation and academic achievement in one nursing school in order to refine the entrance selection system. Methods: Subjects were 405 nursing students (female : male = 385 : 20, first grade = 155, second grade = 138, third grade = 112). They were given the Student Adaptation to College Questionnaire (SACQ) purchased from Western Psychological Service. SACQ is composed of 67 questions and subdivided into 4 subcategories: academic adjustment, social adjustment, personal-emotional adjustment, and attachment. Student college adaptation scores and academic achievements were analyzed with reference to the entrance selection system (rolling admission vs. regular admission) by SPSS 22.0. The rolling admission system recruited students based on high school records only while the regular admission system was based on both high school records and the College Scholastic Ability Test (CSAT). Results: Total College adaptation score, personal-emotional adjustment score, and academic achievement were higher in regular-admission students than in those admitted through rolling admission. Academic achievement for first-grade students was higher in regular-admission students than for those admitted through rolling admission, But the difference in academic achievement became null as students were promoted to the second and third grades. Conclusion: Students recruited using both high school records and the CSAT showed better college adaptation and higher academic achievement.

Super-refraction of radar beams tends to occur primarily under a particular vertical structure of temperature and water vapor pressure profiles. A quality control process for the removal of anomalous propagation (AP) ehcoes are required because APs are easily misidentified as precipitation echoes. For this purpose, we collected X-band polarimetric radar parameters (differential reflectivity, cross-correlation coefficient, and differential phase) only including non-precipitation echoes (super-refraction and clear-sky ground echoes) and precipitation echoes, and compared the echo types regarding the relationships among radar reflectivities, polarimetric parameters, and the membership functions. We developed a removal algorithm for the non-precipitation echoes using the texture approach for the polarimetric parameters. The presented algorithm is qualitatively validated using the S-band Jindo radar in Jeollanam-do. Our algorithm shows the successful identification and removal of AP echoes.

This paper examines the impact of internal migration on wage growth among college graduates using Propensity Score Matching methods. We define migration as moving between Seoul Metropolitan Area (SMA) and non-SMA based on the locations of graduates' first and second jobs. We also take the direction of migration into account for examining the wage premium in SMA. In order to estimate the impact of migration on wage growth, we use the Graduate Occupational Mobility Survey (2010GOMS) coupled with other supplementary data such as College Scholastic Ability Test score and local characteristic variables. The results reveals that graduates moving from SMA to non-SMA do not experience significant wage growth. However, we find that graduates moving from non-SMA to SMA experience an increase in their monthly wage about 170,000~186,000 KRW on average (9.5~10.3% of their monthly wage on the first job).

When teachers make up assessment questions regarding the content area that contains shapes and graphs, they should present the pictures so that their role might be represented properly. We exhibited the process of constructing shapes and graphs utilizing GeoGebra, and simultaneously analyzed the process of developing and revising questions using this and awareness changes in teachers who participate in the teacher's training focused on improving professionalism for making up questions such as CSAT(College Scholastic Ability Test). Through the survey they mentioned that making questions utilizing algebraic construction overcame the limitations of making up questions and played an instrumental role in developing creative questions. Based on the results, We suggested effectiveness of making up questions utilizing algebraic construction. Our intention was to improve the skills of teachers for making up questions such as CSAT and to suggest implications about it.

This study was performed to investigate the relations between dietary habit and academic achievement, subjective health judgement, and physical status. The subjects consisted of freshmen in university and answered to questionnaires through the Internet. The questionnaire consists of the dietary habit, academic achievement (College Scholastic Ability Test), subjective health judgement, and physical status during their 3$^{rd}$ grade in high school days. Data were collected from 3,612 people. Over 33% of respondents had their breakfast daily. Subjects who had breakfast below twice per week were 37.9%. The major reason of skipping breakfast was lack of time to eat breakfast (62.8%). The subjects who recognized the importance of breakfast were 80.6% (p＜0.001). More than half (52.7%) thought that dinner was most tasty. People who ate breakfast regularly had a tendency to recognize their health state were in good health (p＜0.01). There was no significant difference of BMI (body mass index) according to the frequency of breakfast per week. The subjects who had their breakfast regularly and well-balanced dietary habit reported higher marks in the College Scholastic Ability Test. In contrast, the subjects who rarely had breakfast showed poor marks of academic achievement and subjective health judgement. According to these results, a good dietary habit is considered to be important to academic achievement and confidence in health. Therefore we suggest the school breakfast program and nutrition education program should be required for teenagers. In addition, the findings from this study would provide the basic information for nutrition education in Korean teenagers..

Mathematical, verbal, and spatial abilities are known as three important indicators for the success in the STEM disciplines. In this study, Purdue Spatial Visualization Test-Rotation, College Entrance Scholastic Aptitude Test- Math and Verbal score of engineering freshmen students have been used to find the relationships among these areas. In addition, gender differences in spatial visualization, verbal achievement and mathematical achievement have been investigated, too. In this research, I found that gender difference was highest in spatial visualization ability, followed by verbal achievement and smallest in mathematical achievement. Substantial number of male students possess high level of spatial abilities, but only half of female students were at the same level where their male colleagues were. The correlation between spatial ability and mathematical ability was negligible, contrary to former researches on elementary and middle school students. But the correlation was stronger for female students than male students. The correlation between mathematical achievement and verbal achievement was negative. It reflects the fact that when one section of SAT score is low, score of other sections should be higher to get admitted to college. Gender difference in mathematics was smallest for high achieving spatial ability group. For low spatial ability group gender difference in mathematics achievement has been observed, too. To find the combined contribution of spatial and verbal abilities to mathematics achievement, students were divided into 4 ability groups. Mathematics achievement decreased in the order of (1) high spatial -low verbal group, (2) low spatial - low verbal group, (3) high spatial - high verbal group, (4) low spatial - high verbal group.
