The purposes of this research are to identify the subjective perception type of science and engineering graduates about good university and to analyze the differences of their undergraduates' experiences among types. Using Q methodology, 29 statements about a good university, reflecting on the previous research as well as quality assurance criteria in higher education, were administered to 16 science and engineering graduates for ranking using a Q-sort procedure. As a result 16 graduates were classified into three types according to their preference for 29 statements. Type 1, oriented student experience, recognized that a good university encourages students to participate in various activities and experiences. Type 2, oriented institutional outcomes, recognized that a good university is ranked high in criteria such as employment rate, research outcome, and entrance exam scores etc. Type 3, oriented educational activity, recognized that a good university is regarded as a community focusing on teaching and learning. Finally, considering the finding of the research, some pedagogical and administrational implications were suggested for quality improvement in higher education.

In this paper, we analyze the influence of mathematics teaching-learning for high level math problems of A-type of mathematics section on the College Scholastic Ability Test(CSAT). To analyze the influence, we compare and analyze units and field of questions set at examinations based on the rate of wrong answers in A-type mathematics test of the CSAT from 2012 to 2016. Also, we study the recognition of academic high school students and teachers about units and fields on math which need to allow more time to improve grade for A-type of mathematics section on the CSAT. We found following facts. First, high level math problems determining rank of high rank students on the CSAT was taken mostly from the unit related a exponential function and a logarithmic function. Second, these problems need more time for a calculation rather than an ability for students to deepen their understanding of the concept and quality of education. Third, high rank students spend a lot of time to study more important units and fields of mathematics on the CSAT such as a exponential function and a logarithmic function, and teachers spend a lot of time to teach them.

In order to propose effective learning methods to teach basic mathematics course for students of business administration, we conducted the survey on recognition and attitude on mathematics subjects, and analyzed academic achievements of the business mathematics as a basic mathematics course in relation to the results of the survey. First, we investigated learning contents and problems difficult for students to understand in the course, and presented the instructional method and significance of them with examples. These learning contents and problems were collected from the students using the mathematics cafe. Furthermore, we analyzed types of the incorrect answers on the midterm and final examinations in the business mathematics. Although it is difficult to generalize the finding to all of the business administration students due to differences in academic level and educational environment, much work has been put in to present learning method of the business mathematics for students of business administration.

This study aims to analyze the similarities and dissimilarities of various versions of <Heungbu-jeon> at both micro- and macro-levels using contents analysis techniques and the Hamming distance metrics. The 28 versions of <Heungbu-jeon> were segmented into 341 content units, and for each unit, the value of the content type was encoded. The dissimilarities between content types were compared among all versions by the content unit, respectively. The (dis-)similarities based on the content types of the 28 versions were aggregated and transformed into a distance matrix. The matrix was interpreted by multi-dimensional scaling, resulting into the two-dimensional coordinates. By visualizing the results by multi-dimensional scaling analysis, it was confirmed that the versions of <Heungbu-jeon> can be broadly divided into two groups. Hierarchical clustering and phylogenetic analysis were applied to analyze the clusters of the 28 versions, using the same distance matrix. The results showed that there are five clusters based on the micro-level analysis of (dis-)similarities within two major clusters. This study demonstrated the usefulness of applying digital humanities methods to encode the content of classical literary versions and analyze the data using clustering analysis techniques based on the (dis-)similarity of literary content.

This study is a descriptive research study conducted to provide useful preliminary data that is helpful for self-initiated learning through a preference trend-based learning method by analyzing the personality types of university students in an area. In this study, the self-administered MBTI form $M^{(R)}$ test was performed on 695 students of 10 departments at K University, from September 18 to 22, 2017, using an automatic scoring system. Collected data was analyzed with descriptive statistics and Chi-square test, using the SPSS Win 22.0 Program, to sort the target students into one of 16 different personality types and examine psychological function and temperament by their personality. Differences in personality type preference by gender were as follows: for judging function, the male students had a strong preference for the T type (thinking type) while the female students showed a high preference for the F type (feeling type), and in the case of the pattern of behavior and lifestyle, the male students and the female students had a strong preference for the P type (perceiving type) and the J type (judging type), respectively. In addition, there were significant differences for each major and each department in personality type, psychological function and temperament. In conclusion, personality type was found to vary by gender, major and department. It would be necessary to develop a manual for learning methods reflecting individual preference.

The purpose of this study is to investigate the self-directed learning readiness of university students' majored in science and engineering as life-long learners, and to analyze the relationship between self-directed learning readiness and learning style. Participants of this study are 142 students majored science and engineering in H university of Chung-nam province to participate in taking self-directed learning readiness tests and Kolb's learning style tests. The results of this study are as follows: First, the average of overall participants' self-directed learning readiness is 3.41, which is possibly regarded as 'an average' according to Guglielmino & Guglielmino (1991)'s interpretation of scores. Second, among four basic scales of participants' learning styles, the highest is found in Active Experiment (AE), the lowest is found in Abstract Conceptualization (AC). In addition, the highest thing of the four learning styles found among the participants is divergers (36.6%) and the lowest is convergers (13.4%). Finally, this study compares the high-level and low-level groups of self-directed learning readiness score with learning style. there is a statistically significant correlation between the score of self-directed learning readiness and CE, AC (p=.01). Therefore, self-directed learning readiness is related to learning style.

The mixed cropping system is a centuries-old cropping technique widely practiced in farmers' fields worldwide. Increased plant diversity enhances farmland biodiversity, which improves grain yield and quality. However, the effect of growing different rice cultivars simultaneously has rarely been investigated. In the present study, six glutinous rice cultivars were selected, and two mixture cultivation methods were determined according to plant height, grain yield, and color. Colored and glutinous rice are used for specific purposes by consumers because of their color and nutritive value. Six glutinous rice varieties, including aromatic and colored rice, were included in the combination interplanting trials. The results showed that, compared with the corresponding monocropping systems, almost all combinations of the mixed cropping systems had advantages in yield-related traits. Compared with monocropping systems, mixed cropping systems increased the number of panicles per plant and maturation rate by 20% and 10%, respectively. An increase of 18-20% grain yield was observed in mixed cropping plots compared with that in plots which grew only a single rice variety. Some rice varieties, such as green colored rice 'Nogwonchall' and black colored rice 'Chungpunghukhayangchall', exhibited 18-22% increased yield when they were planted in combinations. The high yields were primarily owing to improved light interception and reduced lodging, although other factors (for example, reduced severity of disease) may have also contributed.

This study has been conducted to identify the types and longitudinal changes in the career values of students in science core school. Data collected from 174 students in science core school were analyzed using 11 career value items. First, this study found that there are three types of career value shown in students in science core schools. Second, the career value of students in science core school did not differ by their track. Third, many students of science core high schools have little or no change in their career value values depending on the time of collecting data. However, some students show rapidly changing career values. These findings suggest the need for individualized career education based on the changing trend of students' career values.
