  • Buildings are responsible of major energy consumption globally. In addition, they are linked to thermal comfort. The need to provide comfort becomes more crucial in schools as they are the place where students learn, and develop their skills. This research aims to investigate the energy responsiveness of new and traditional school building design, where major variation in form, amount of external walls and glazing are different. The research focused on indoor microclimate condition of selected schools in the city of Jeddah where the climate is hot and humid using advanced tools for monitoring. The research uses advanced energy equipment to measure several aspects such as floor temperature, roof temperature, globe temperature and other factors which can lead to predictable thermal comfort of users. The findings suggest that a larger area of glazing shielded from sunlight has a greater influence on both indoor condition and general thermal sensation. The finding also suggests that the glazing ratio is a major contributor on indoor thermal pattern which can result in an increase in temperature profile between from $7-10^{\circ}C$. The findings of this research can assist in the improvement in the design of the prototype school building in hot and humid climate.

  • Purpose: This study was conducted to develop and implement a case-based small group learning program on the care of children with infectious disease, and to examine its effects on knowledge, attitude and preventive practice behaviors of daycare center teachers compared to a control group. Methods: Based on the need assessment, the case-based learning program for the management of infectious children was developed. For this quasi-experimental study, 69 teachers were recruited from 14 child daycare centers in a city located in J province. Thirty four teachers were assigned to experimental group and participated in the case-based small group learning once a week for 5 weeks. Data were analyzed using the SPSS 18.0 program to perform ${\chi}^2$-test and t-tests. Analysis of covariance was used to treat the covariate of the number of assigned children between experimental and control groups. Results: The experimental group showed significantly higher posttest scores in knowledge, attitude and preventive practice behaviors than those of control group (p<.001). Conclusion: These findings indicate that case-based small group learning is an effective educational strategy for daycare center teachers to learn infection management through the emphasis of self-reflection and discussion.

  • The aim of this study is to analyze STEAM lessons focused on the learner's learning. This study was conducted on 4th-graders in Y city, Kyung-gi province. The lessons were based on a joint teaching plan for students through the teacher learning community (TLC) with three teachers from the same school. Each of the three classes that conducted the class was selected and analyzed as the main center of observation by three students. The conclusions from this study are as follows: First, we identified that different levels of learners are learning in STEAM lessons through a learner-centered class analysis. Some students arrived on their own by taking the initiative in class, others by consulting with a group of friends, and others needed active teacher guidance to learn. Second, Depending on the level and characteristics of the students, some learning criteria were not reached. Some students need guidance at a glance level, and others need individually instructed or guided activities. Teachers need to keep an eye out for students and give them an appropriate level of guidance during class. In STEAM lessons, it appears that students of different levels and characteristics can immerse themselves in their own way, as well as the clear guidance of activity for their students.

  • The study was designed to learn about features of landscape trees and shrubs on an exclusive area-specific outer space planting plan in Noeun Apartment Complex in Daejeon Metropolitan City. the exclusive areas were no more than $60m^2$ and $85m^2$ and the landscape areas ranged from 15% and 30%, respectively according to exclusive area-to-plottage ratios. The study showed that trees were likely to be more densely planted in exclusive areas not exceeding $60m^2$ than in exclusive areas over $85m^2$. It also found that the greater the exclusive areas were, the larger the number of species became. Regardless of the size of an exclusive use, however, the species number of evergreen trees and shrubs remained small, while there was no remarkable difference in vegetation due largely to a massive influx of special trees or shrubs such as Eastern white pines (Pinus strobus) and Korean azaleas (Rhododendron yedoensis var. poukhanense). The introduction of trees with the height over four meters and the diameter of breast height (DBH) exceeding 15 meters was strictly limited to Japanese red pins (Pinus densiflora) and Japanese zelkovas (Zelkova serrata). In conclusion, it is necessary for us to introduce fresh species of trees and especially develop evergreen trees and shrubs to make the environment of the apartment complex more comfortable and make a vegetation experience feasible.

  • To reduce the noise in the noisy speech, it is desirable to change the parameters of the speech processing system according to the noise intensity to reproduce a good quality speech. This paper proposes an estimation method of noise intensity using a three layered neural network, which is able to learn the three graded speeches that is degraded by white noise or road noise. Experimental results demonstrate that the noise intensity could be estimated by the neural network. Even if the speakers and speech data are different from the training data, estimation rates for the noise intensity can be estimated by the neural network with an average accuracy of $95\%$ or more for white noise.

  • This thesis is based on an in-depth interview on participation experience of ten immigrants who reside in S Multi-cultural Family Support Center that is located in Gyeonggi-do in Korea Immigration & Integration Program(KIIP). The purpose of this research is to present through it's basic data for improvement in the operation of KIIP in the future by grasping participation process in KIIP that the immigrants have experienced, problems involved in their operation, and related requirements. Major results of the research are as follows: First, the motive for the immigrants' participation in KIIP was to acquire Korean nationality, learn Korean, and prepare for their future in Korea. Second, as a difficulty in participation in KIIP, access to educational institutions loomed large. Third, regarding improvements in the operation of KIIP, marriage immigrants needed to continue Korean language education, whereas other immigrants revealed a demand for opening evening classes or weekend classes. In the final analysis, it seems that for KIIP to provide an opportunity for the immigrants to have a vision for their life in the future, as well as for its realization in Korean society, policy-oriented institutional support that pays attention to their life situation and demands is badly needed.
