  • This study examined the instructional influences of MBL programs on elementary school students' science achievement, scientific inquiry skills, and science learning motivation. The perceptions of students and their teacher toward science classes using MBL programs were also examined. The subject of this study was sixty four 4th grade students from two classes. The experimental group engaged in science classes that applied MBL and the control group engaged in traditional science classes based on the textbook and experiment workbook. As results, there was no significant difference in academic achievement, scientific inquiry skills, however, were significantly higher for the experiment group compared to the control group. There was also significant difference in the relevance and confidence, the sub-categories of science learning motivation. In the analyses of students' perceptions toward science classes using MBL, students showed positive perceptions in aspects of interests of science classes, content comprehension, and convenience of experiments. The teacher also showed positive perceptions using MBL in elementary science classes. Educational implications of appling MBL in elementary science classes were discussed.

  • The purpose of this study was to analyze the difference between eye movements according to science achievement of elementary school students in observation situation. Science achievement was based on the results of national achievement test conducted in 2012, a random sampling of classes. As an assessment tool to check observation test, two observation measure problems from TSPS (Test of Science Process Skill; developed in 1994) suitable for eye tracking system are adopted. The subjects of this study were twenty students of sixth grade who agreed to participate in the research. SMI (SensoMotoric Instruments)' iView $X^{TM}$ RED was used to collect eye movement data and Experiment 3.1 and BeGaze 3.1 program were used to plan and analyze experiment. As a result, eye movements in observation test varied greatly in fixation duration, frequency, saccade, saccade velocity and eye blink according to students' science achievement. Based on the result of eye movements analysis, heuristic search eye movement was discussed as an alternative to improve underachievers' science achievement.

  • The landslide disaster damage has been increased by mountain development, leading to construction of educational facilities, medical facilities, petty industrial facilities, and large housing complexes. Therefore, effective regulation is required as an effort in urban planning solutions. For suggesting specific mitigation strategies on urban landslide, this study aims to define evaluation criteria for urban planning management of debris-flow disaster. AHP (Analytic Hierarchy Process), one of the multiple criterion decision making methods, was utilized in this study. This study makes use of 16 sub-criteria under the framework of hazard, exposure, and vulnerability, and well-planned expert survey measures their weights. The weights are also applied to evaluate each grid in urban space (min $10{\times}10m$) and classify it with red, orange, yellow, or green grade so that areas at higher risk are clearly identified. This study concludes that the suggested method is useful to support a strategies for urban planning management of debris-flow disaster, particularly in a GIS base.

  • The purpose of this study is to classify the stress into groups and analyze their differences in self-consciousness, and appearance management behavior. Questionnaires were administered to 377 middle and high school girls living in Deagu metropolitan City. Frequency, factor analysis, reliability analysis, cluster analysis, ANOVA, Duncant-test, and t-test are all used for data analysis. Our findings show that stress developed due to several reasons: the categories are as follows into grades-related low stress, exam-related high stress, and society-related high stress. For the purposes of our study, we labeled self-consciousness as a combination of being socially and privately self-consciousness and showing signs of social anxiety. Appearance management behavior deals with esthetic plastic surgery, clothing harmony, weight management, hair management, health care, skin care, and meal management. Stress shows a significant correlation with the sub-variable self-consciousness and appearance management behavior. The groups show a significant difference in the self-consciousness, and appearance management behavior. There is also a significant difference among stress, self-consciousness and appearance management behavior by grade. The students in seemed to recognize that their appearance can be improved by dressing up and managing their outwardly appearance. Teachers should educate students to have the variety of views on the meaning of beauty. In addition, schools need to develop programs to educate student about appearances, as the student's interests differ due to the stress type of the adolescent.

  • This study deals with rural village development project of Gasangri, Yeongcheon city area, based on the use of the cultural factors and strengthening them in study area. Unlike other cases of today's Korean rural village development projects, this plan keenly concerns not only for tourists but also for the village people. Since culture means the quality of life also, this project especially deals with 'community', 'well-being', and 'convenience' for the inhabitants. On the other hand, it attempts to connect with "Cyan Museum", which is the first grade art gallery remodelled from closed school, to make village of culturally abundant atmosphere. In result, seven sub-projects of the expansion of basic living foundation, and two improvement of landscape in area have planned. Among stereotype of rural development projects and similar programs of tourism, the project makes difference on targeting for the meaning and resource of place culture.

  • The function of subgrade in the railway is to support track load on the subgrade as well as train load. Unlike the traditional railway, the uppermost subgrade layer in the Gyeongbu high speed railway was constructed as the reinforced road bed. The reinforced road bed comprises sub-ballast in the upper part and grade ballast in the lower part. The filling material such as soil and rocks in the subgrade can be settled by consolidation of original ground, compression due to self weight, plastic displacement due to train operation, and unequal settlement due to embankment material or improper compaction, therefore many efforts have been given for sufficient compaction and use of proper filling materials in the construction stage. The purpose of this study is to investigate the deformation state of subgrade in the Gyeongbu high speed railway. The investigation on the subgrade settlement was performed by choosing representative sections suspected to be settled based on the previous GPR test results and track maintenance history, measuring the settlement for some time period after installing settlement measuring instruments on and under the reinforced road bed. and analyzing the long-term subgrade settlement data from monitoring system which was installed at the construction stage of the high speed railway.

  • The purpose of this study was to examine the effect of three types of praise activities on school adjustment of sixth graders. We assume that there are three types of praises; Verbal reinforcement, Encouragement, and Social acknowledgment. The study is based on pretest-posttest experimental design. The subjects of this study were 55 six- grade students who enrolled to two classes of an elementary school located in Busan. One class (26 students) was an experimental group and the other class(29 students) was a control group. Three types of praise activities were applied to the experimental group for 11 weeks. The activities were composed of classroom activities for understanding of the concept of praise, online activities, praise card activities for practicing three types of praises. School Adjustment Scale developed by Lee Young-Sun(1997) was administrated to all the subjects as the pre and post-test. To verify the effects of the experiment, ANCOVA was conducted. The treatment group showed a statistically significant increase in school adjustment, but the control group that received a neutral intervention did not.
