  • This study aims to find how storytelling classes using fairy tales related to science museum exhibits have an effect on positive experience about science. For this study, the theoretical background and preceding studies on the relevance of science education and literature were collected and based on the characteristics of assimilation and the educational value of assimilation, naturally connected to the exhibits in relation to their own life, so that individuals could explore science even out-of-school. Four types of activities were developed by linking four fairy tales mentioned in elementary school textbooks to the G science museum exhibits. Seven elementary school teachers verified the validity of the activity materials. Classes through the developed activity materials were conducted four times in a row, one and a half hours at every turn for 10 students. A positive experience about science test was conducted on the students in a study to confirm that this activity has caused significant changes in science academic emotion among sub-domains of positive experience about science. In order to find the factors that affected the science academic emotion, we interviewed the students in the study and their parents. The results of this study show that the use of fairy tales related to science museum exhibits has led to a significant change in science academic emotion by reducing the burden of learning through the exhibition experience at the science museum, which creates scientific curiosity and recognizes them as a playground.

  • The purpose of this study is to compare the satisfaction of the urban parks and to classify and assess the environmentally-friendly behaviors in the urban parks. For this purpose, the park user's behaviors and satisfactions were surveyed in 10 parks in Seoul and its suburb area. Parks are divided into 2 types, the walking-distance parks and the metropolitan parks, by time to reach, visit frequency and visit purpose. The park users are generally satisfied with the facilities, but not satisfied with some specific items, such as cultural facilities, accommodations for the handicapped, safety facilities and sports facilities. The environmentally-friendly behaviors are positively assessed in general, but the behavior of the natural experience was negatively assessed. The environmentally-friendly behaviors in the urban parks are classified into 2 factors; the experience factor and the activity factor. The parks are categorized into 3 types by these factors. For type I parks, the experience factor is dominant, but the activity factor is relatively low. For type II parks, the both factors are low and the parks are necessary to improve. And type III parks are positively assessed in the aspect of the environmentally-friendly behaviors, even though some park are necessary to complement.

  • As a construction project is recently becoming large-scaled and complex, construction process plan and management for successful performance of a construction project has become more important. Especially a reasonable estimation plan of activity duration is required because the activity duration is directly related to the determination of the entire project duration and budget. However, the activity duration is used to estimate by the experience of a construction manager and past construction records. Furthermore, the prediction of activity duration is more difficult because there is some uncertainty caused by various influencing factors in a construction project. This study suggests an estimation model of construction activity duration using neural network theory for a more systematic and objective estimation of each activity duration. Because suggested model estimates the activity duration by a reasonable schedule plan, it is expected to reduce the error between planning duration and actual duration in a construction project. And it can be a more systematic estimation method of activity duration comparing to the estimation method by experience of project manager.

  • Purpose : The purpose of this study was conducted to compare the fear of falling, self-efficacy and fall prevention behavior according to the fall experience of the elderly. Methods : The subjects of this study were 162 elderly in B metropolitan city. The data collection period was from September 10th to November 30th of 2018. The collected data was processed using SPSS 21.0 and was analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test. Results : The mean scores for fear of falling according to the fall experience and no fall experience of the elderly were 2.28±0.63 and 1.84±0.64 respectively and the results showed that fear of falling (t=4.26, p<.001) and self-efficacy of falling (t=3.88, p<.001) were significantly different between the two groups, but the mean scores for fall prevention behavior according to the fall experience and no fall experience of the elderly were 1.63±0.20 and 1.67±0.17 respectively and there was no significantly different in fall prevention behavior (t=-1.16, p=.25). Fear of falling according to the fall experience was significantly different by age (F=3.25, p<.05) and physical activity related to daily life (F=13.22, p<.001). Self-efficacy according to the fall experience was significantly different by age (F=3.03, p<.05), income per month (F=3.74, p<.05) and physical activity related to daily life (F=11.99, p<.001). But fall prevention behavior was no significantly different of general characteristics. Fear of falling according to the no fall experience was significantly different by age (F=3.37, p<.05), marriage status (F=3.37, p<.05), education level (F=5.15, p<.01), income per month (F=3.58, p<.05) and physical activity related to daily life (F=15.71, p<.001). Self-efficacy according to the no fall experience was significantly different by sex (t=2.32, p<.05), age (F=5.20, p<.01), marriage status (F=5.04, p<.01), education level (F=6.55, p<.001), income per month (F=5.99, p<.001) and physical activity related to daily life (F=18.86, p<.001). Fall prevention behavior was significantly different by marriage status (F=3.51, p<.05). Conclusion : The results of this study suggest the following : it is necessary to develop a program that can lower the fear of falling in the elderly and to increase the self-efficacy of falling, and to develop an education program that can improve the elderly's practice of fall prevention behavior regardless of the fall experience and to verify its effectiveness.

  • The purpose of this study is to identify contradictions in library internship, and address them. As a case study, students who were enrolled in the internship class opened in the 2016 fall semester in a university in Seoul were interviewed. Through applying Activity Theory, the process of internship and contradictions presented in its process were analyzed. The findings indicate that students were satisfied with their internship experience. The internship experience also makes positive impacts on students in terms of understanding the library and information science and deciding their future career as a librarian. Such contradictions as internship duration, operation of the internship process, level of participation or practice, and overlap of part-time experience in a library were identified. This study suggests to make the internship systematic in order to address the contradictions through that all parties in internship are actively participated in internship and that they share information related with the internship.
