The importance of users on library catalogs cannot be overemphasized. However little is verified about how well the users' needs have been met. The purpose of this research is to explore the characteristics and differences between user groups on library catalogs, and to draw implications for follow-up research. To the end, this research classified the users into four groups: elementary students, middle and high school students, college students, and the general public. Investigated are unique features and differences in searching behavior on library catalogs between the four groups. The data was collected through a survey with 544 users, and analyzed for both frequency test and Chi-square test. The major research results shows that there were statistically meaningful differences between the four groups. Also discussed are several suggestions for more in-depth research.

The purpose of the present study was to investigate personality type with evoked potentials. Teenage students(121 males, 69 females) tested Myers Briggs Type Indicator and raven like discrimination task by evoked potential. Raven like discrimination tasks were made of low, medium and high levels. Conclusively extraversion and introversion while accomplishing the raven like discrimination tasks, showed the significant difference between two groups in the power of concentration. M-Beta(middle beta), Gamma and H-Beta(high beta) were also appeared significant differences between two groups. The sensing and intuition type partially appeared the different tendency of two groups while accomplishing easy and medium of difficulty tasks. Thinking and Feeling type while accomplishing raven like discrimination tasks, showed difference of the concentration power and H-Beta at Fp1. But judgment and perception type did not appear the difference between two groups while accomplishing raven like discrimination tasks of low, medium, and high. These results implied that the personality type can be affected brain wave by evoked potentials.

제7차 컴퓨터 교육과정에 대한 많은 논란과 개선방안이 제기되어 왔지만 경험한 교육과정을 대상으로 성취수준에 대한 연구는 거의 이루어지지 않고 있는 실정이다. 본 연구에서는 2005년도에 대학 신입생을 대상으로 실행했던 컴퓨터 소양 교육과정을 개선하기 위하여 2005년도와 2006년도의 신입생을 대상으로 연차별로 컴퓨터 소양과 활용수준 그리고 양 집단간의 수준 차이를 분석하였다. 이를 위하여 2005년도에 개발된 설문지 사용하여 각 학기가 시작되는 시점에서 학생들의 응답을 분석하였다. 설문자료를 분석한 결과는 다음과 같이 요약할 수 있다. 두 집단 모두 다섯가지의 영역에서 영역간의 수준의 차이가 큰 것으로 나타났다. 컴퓨터통신, 기초기능 그리고 정보윤리 보통 이상의 수준을 보였으며, 반면에 기초지식과 소프트웨어 활용 영역에서 보통 이하의 수준으로 나타났다. 두 집단간의 연차별 수준 차이는 거의 없는 것으로 보였다. 컴퓨터통신과 정보윤리 영역에서 미미하나마 2005년도에 비하여 평균이 약간 증가하였으며, 나머지 세 개의 소프트웨어 활용과 기초지식 및 기초기능 영역에서는 각각의 평균이 0.05 이하의 차이를 보이고 있다. 대학 신입생의 컴퓨터 소양교육을 위한 두 집단간의 연차별 선수 지식의 수준차이는 없는 것으로 나타났다.

This study aims at analysing the differences on visitors' satisfactory level based-on personal lifestyles in a Korean national park. The lifestyles were classified and differences of satisfaction level among the groups were verified from a questionnaire survey in Bukhansan National Park, Korea. Lifestyles by the factor analysis, 5 factors were sorted. 4 clusters classified as the suitable clusters by clustering analysis. As a result from differences of satisfaction level on the lifestyle types, satisfaction level for each cluster has been shown to be statistically meaningful difference. Satisfaction level in active tendency cluster was the highest among the 4 cluster types(Social>Individual>Passive cluster). Satisfaction differences according to the lifestyles suggests that a fragmented approach is needed rather than an integrated approach for managing facilities and programs in Korean national park system.

The purpose of this study was to examine the effects of the level-differentiated laboratory activities suggested by the 7th national curricula compared to the in-depth level activities only and supplementary level activities only. Two hundred 7th grade students attending a coed middle school were selected for this study and divided into three groups; level-differentiated, in-depth, and supplementary group. In each group, the students were subdivided into the in-depth level and the supplementary level by the formative test after completing the basic learning course. The in-depth and the supplementary laboratory activities were developed and engaged to the respective students in the level-differentiated group for one semester, while only the in-depth activities were engaged to the in-depth group and only the supplementary activities were engaged to the supplementary group. To examine the effects of treatments, the science knowledge test and the inquiry process skill test were administered before and after treatments and the students' opinions about the level-differentiated instruction were surveyed. The results showed that there were significant differences in the science knowledge achievements between the groups while no significant difference was found in the inquiry process skills. Post hoc analysis showed these differences were found between the level-differentiated group and the supplementary group. After the activities, most students in the level-differentiated group responded positively on doing level-differentiated activities except a few students in the supplementary level, These results justify the effectiveness of the level-differentiated laboratory activities compared to the supplementary only laboratory activities in middle school science classes.
