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.

Background: The purpose of this study is to report the effect of balance training through various ankle inclination on dynamic balance in healthy adults. Methods: This study was participated in 20 healthy subjects. Twenty healthy adults were randomly divided into 10 ankle inclination group and 10 flat group, 3 kinds of exercised were performed in $30^{\circ}$ of the plantar flexion, $0^{\circ}$ of the neutral angle and $30^{\circ}$ of the dorsiflexion. Above 3 kinds of exercises were also performed in the flat group. Dynamic balance of each group was evaluated using a Figure-of-8 hop test, Up-down hop test, and Functional reach test before and after the experiment. Results: In the ankle inclination, the post-experiment showed a significant difference in Figure-of-8 hop test, Up-down hop test, and Functional reach test in comparison to pre-experiment(p<.05). Conclusion: The exercise applied in the ankle inclination is effective in improvement of the dynamic balance.

This study presented a development of a phototactic apparatus for pest monitoring. We carried out behavioral experiment against various pest species by using the phototactic chamber. Consequently, the phototactic apparatus was confirmed suitable result of behavioral experiment. Therefore, we believed that the test apparatus help to understand the phototactic responses of various pests.

We consider a life testing experiment in which several two-component shared parallel systems are put on test, and the test is terminated at a predesigned experiment time. In this thesis, the maximum likelihood estimators for parameters of Freund's bivariate exponential distribution under the system level life testing are obtained. Results of comparative studies based on Monte Carlo simulation are presented.

Purpose : The purpose of this study is to compare the initial effect of nerve mobilization (NM), static stretching (SS), and contract-relax (CR) techniques to find the best method in improving hamstring flexibility and gait function in patients with hemiplegia. Methods : Eleven patients with hemiplegia were included in this study. Passive knee extension (PKE) range of motion and the sit and reach (SR) test were used to measure hamstring flexibility, while timed up and go (TUG) and the 10m walking (10MW) test were used to measure the subject's gait. Measurements on each test were assessed prior to the experiment, immediately following the experiment, and 30 minutes after the experiment. Analysis of the results utilized a repeated measures analysis of variance to examine hamstring flexibility and the difference in walking ability. Results : The results suggest significant increases in NM, SS, and CR techniques as they relate to hamstring flexibility (p<.05) following (both immediate and 30 minutes post experiment) PKE range of motion and the SR test, but post-hoc showed no significant difference between the three techniques (p>.05). Additionally, the results suggest significant increases in NM, SS, and CR techniques as they relate to gait function (p<.05) following the TUG test, but found no significant difference in the 10MW test (p>.05). Post-hoc analysis between the three techniques suggests that only the NM technique significantly changed gait function. The time of TUG and 10MW test showed no significant difference between the three techniques before an experiment, just after an experiment, and 30 minutes following the experiment according to the measurement points in time (p>.05). Conclusion : This study suggests NM, SS, and CR techniques immediately improve hamstring length and flexibility while improving gait function in patients with hemiplegia.

The purposes of the 'Students' Science Inquiry Experiment Tournament' which is one of the 'Students' Science Inquiry Olympic Tournaments' are; 1) cultivate students' intellectual interests, inquiry abilities, and scientific attitude dealing with students' scientific reasoning abilities, problem solving abilities, and experimental apparatuses operation abilities. 2) contribute substantiality of science education through experimental inquiry learning. 3) make the ground of basic science development of the future society by selecting excellent students who have talents for science. 4) elevate science teachers' morale by this tournament. The test items set and evaluation results of the tournament were analysed in this study. The results of this study were ; 1) the discrimination ability of the paper-and pencils test and the experiments were low because the students' scores of the items were not normally distributed and standard deviations were very small values. 2) most of the tournament participation students did not answered to the subjective type test items. 3) according to the responses of the tournament participation students, the tournament contribute to the students' interests in science. But the opinion was dominant that the tournament didn't contribute to school science education improvement.

Two rice varieties, 'Oochikara' with large grain and 'Hwayeongbyeo' and their progenies (F$_1$, F$_2$, B$_1$ and B$_2$) were tested to understand gene action of morphological traits of rice grain and their relationships. The evaluated traits were 1,000-grain weight, grain length, width, thickness, length-width ratio and chalkiness of brown rice. Correlation between grain weight and chalkiness was highly significant in the all progenies, and grain length were not associated with width and thickness in an F$_2$ population. Scaling test and jonit scaling test revealed that inheritance of grain traits were fitted to additive-dominance model without epistasis. Additive effects for the traits were much greater than the dominance effects.

과학영재교육의 사례를 살펴보는 것은 영재교육의 형성적 평가라는 차원에서 의미가 있다. 이에 본 연구에서는 학생들의 선발과정에서 얻어진 성취도검사자료, 구술시험, 창의력 검사, 문제해결능력검사 결과와 학생들이 입학후의 과학수행이 어떤 관계가 있는지를 알아보고자 했다. 과학영재 특히 지구과학반 7학년과 8학년을 대상으로 한 본 연구는 과학탐구의 기본적인 요소인 실험설계능력에 초점을 맞추었다. 실험설계능력으로 나타난 실제적인 과학 활동 수행의 결과가 선발과 어떤 관계를 갖는가를 알아봄으로써 과학영재프로그램의 재조명을 꾀하고자 하였다.
