Since 2019, elementary schools have been teaching software to students, so pre-service teachers should have the ability to teach software. Also, in the COVID-19 situation, pre-service teachers need the ability to teach software online. The purpose of this study is to investigate the effectiveness of online software education for preservice teachers. After providing online software education to preservice teachers, we analyse the results and examines whether online software education is effective. In this study, we define 55 learning elements by analyzing the achievement standards that can evaluate the software education ability of preservice teachers. We figure out whether pre-service teachers have acquired the ability to provide online software education to elementary school students. As a result of the study, we concluded that pre-service teachers who received this online education could conduct software education online in elementary school.

This study examined a difference in a change of understanding and recognition on STEAM Education before and after participating in STEAM Education of university students majoring in teaching profession of engineering system who took part in 'STEAM Education of being made together with undergraduates for 2016' as part of the project for a center of supporting STEAM pre-service teachers. As a result, the pre-service teachers majoring in teaching profession of engineering system could be confirmed to have been improved the understanding and sympathy level with STEAM education as a whole following the execution of the program. Comparing it with other majoring system, the pre-service teachers majoring in teaching profession of engineering system were shown to be a little low in pre-perception or satisfaction, but were indicated later to have high intention of participation in STEAM education. This suggests that the pre-service teachers majoring in teaching profession of engineering system recognize the importance of STEAM education in the engineering education, but are feeling pressure about interpersonal communication. Accordingly, it is time that there is a need to have a system of officially providing the implementation of STEAM education and an opportunity of experience in the education for pre-service teachers aiming at the engineering education for future generation.

Some conclusions derived from the study are as follows : 1) Most conventional information retrieval systems require users do precisely that specify the information they require, but user's information needs are not always precise. 2) Information need arise from when users are in an anomalous stats of knowledge about some problem, so user's information needs are not always precise. 3) Information retrieval systems must assist to users make themselves correct, complement, and specify their information need. When information need arise, systems should understand the state of knowledge and will be design to present and specify their ill-defined potential information need. 4) Existing information retrieval techniques need a tool to complement current its disadvantages and to enhance retrieval efficiency. Browsing searching will be a role such as a tool. 5) Browsing searching can understand user's state of knowledge and assist to specify not only pre-searching information need but also changed information need during searching progress.

Since the current tendencies show us the increasing number of cerebral palsy children and the standard longevity, we need to find out more research about the following various problems. Therefore I have tried to figure out the difference of oxygen saturation and heart rate between before ambulation and after. Objects chosen are 17 C.P children on the process of treatment those who were able to walk and 8 normal children in Ah-San hospital, Gang-Nung. They haven't had either any operation or suffered heart disease and I measured their oxygen saturation and heart rate by using pulse-oximeter and are analyzed by SPSS (10.07 version). Results are the followings; 1. There was no difference of oxygen saturation and heart rate between pre-ambulation and post-ambulation of normal and spastic hemiplegia children. 2. There showed the significant statistic difference of oxygen saturation, heart rate between pre-ambulates and post-ambulation of normal and spastic diplegia(p<.05). 3. There was no difference of oxygen saturation, heart rate in C.P between(p>.05), but shows the significant statistic difference in heart rate(p<.05). As I compared the oxygen saturation and heart rate of spastic and normal children on between pre-ambulation and post-ambulation, theres is significant statistic difference on both items (p<.05). However there was no difference of oxygen saturation among hemiplegia, normal and diplegia children while the pulse rate showed the significant difference(p<.05). According to this clinical research, CP children's oxygen saturation and heart rate had no change between pre and post compared to normal children. But there was difference in diplegia. This is why we need to invest time to study these kinds of research about various analysis and comparison of oxygen saturation and heart rate, and furthermore making use of pulse-oxymetry in physical therapy room for the children involved would be beneficial to calculate in accuracy without any discomfort for the patient as well.

In this research, we analysed definitions and examples of conductor and electrolysis concept in middle school science textbooks. We also surveyed 9 senior pre-service teachers' understanding of the concept definitions and appropriate examples. From the analysis of the textbooks, we found that the possibility of misunderstanding of learners is high because of the broad definition concept and narrow list of examples. After confirming the differences among pre-service teachers' understanding of the subject through questionnaires and interviews, they also debated for a need to an agreement on scientific concepts. The pre-service teachers recognized the meaning of social constructivism and the need for an agreement process in teaching science concepts.

This study analyzed the lesson analysis reports and survey of pre-service teachers who have practiced the microteaching in order to identify the reflection of mathematics pre-service teachers. The professors who are teaching pre-service teachers need to propose the examples of an instructional model that can induce the opened reaction and the effective usage of time through interesting topics. In addition, pre-service teachers who have practiced the first microteaching have shown a lot of reflection more than expected. Therefore, to improve the quality of lectures, it is important for pre-service teachers to have experiences of microteaching and reflection.

PURPOSES : This study aimed to analyze the impact the operation of pre-signals at 4-leg signalized intersections and present primary environmental factors of roads that need to be considered in the installation of pre-signals. METHODS : Shift of proportions safety effectiveness evaluation method which assesses shifts in proportions of target collision types to determine safety effectiveness was applied to analyze traffic crash by types. Also, Empirical Bayes before/after safety effectiveness evaluation method was adapted to analyze the impact pre-signal installation. Negative binomial regression was conducted to determine SPF(safety performance function). RESULTS : Pre-signals are effective in reducing the number of head on, right angle and sideswipe collisions and both the total number of personal injury crashes and severe crashes. Also, it is deemed that each factor used as an independent variable for the SPF model has strong correlation with the total number of personal injury crashes and severe crashes, and impacts general traffic crashes as a whole. CONCLUSIONS: This study suggests the following should be considered in pre-signal installation on intersections. 1) U-turns allowed in the front and rear 2) A high number of roads that connect to the intersection 3) Many right-turn traffic flows 4) Crosswalks installed in the front and rear 5) Insufficient left-turn lanes compared to left-turn traffic flows or no left-turn-only lane.

The purpose of this study was to get an implication on teacher education program, by exploring the difficulties pre-service elementary teachers have with their science lessons. 37 pre-service teachers were requested to write an anecdote about their science lessons during their 4 week practicum. By analyzing these anecdotes, the difficulties were grouped into several categories by the researcher, and then reconfirmed by the pre-service teachers themselves. The result showed that there were far more difficulties with practical work (cases: 48), than with content knowledge teaching (cases: 17). Among practical work related difficulties, the most frequent cases were: 1) when they have unexpected result different from scientific theory (cases: 10), 2) when they teach process skill and usage of lab equipments (cases: 8), and 3) when they do not have enough preparation for practical work (cases: 7). Unlike the result of preceding research on secondary pre-service teachers, there was no affective aspect problems. These difficulties also can be divided into 'problems' and 'dilemmas'. Whereas 'problems' can be settled by removing obstacles, 'dilemmas', a conflict-filled situation, require choices between competing values or aims. The use of scientific language, the decision on the level and amount of knowledge they teach, and disposal of unexpected experiment results caused such dilemmas in science lessons. The research results imply practical work should be more strengthened in the elementary teacher education program. And both teacher educators and pre-service teachers need to understand that practical teaching is a complex enterprise accompanying some 'dilemmas'. The role of science teachers as managers of dilemmas could be considered.
