This study started with the cognition of problem that design activities closely related to industries could cause damages to the environment. The purpose of this study was to suggest a new concept of fashion design for environment using pre-consumer textile wastes which are produced in cutting process and used to be disposed in landfill sites. To achieve the purpose of this study, the literatures about fashion design for environment were reviewed, and design process including design development, producing, and presentation was performed. As a result, three fashion designs for environment using textile wastes were suggested. The results of this study were followings. Using pre-consumer textile wastes, this study suggested realistic way of fashion design for environment which is not just showing environment image, but providing practical use as well as preventing the waste of resources. Second, through constructing textile wastes, both 2-dimensional and 3-dimensional designs were possible, and unexpected effects created new value of beauty. Third, because the amount and type of pre-consumer textile wastes are unlimited, this fashion design for environment could be considered as continuous profit model.

In order to promote and comprehend marriage immigrants' culture, it is essential to understand the life of their families in their counties. For this study, data by a Philippine CFO(Commission on Filipino Overseas) has been analyzed, and the study researcher has attended an educational program run by the PDOS(Pre-Departure Orientation Seminar). Also, in order to understand the immigrants' families in their country, interviews have been done with some of the CFO employees, people arranged to immigrate to Korea through marriage, and female immigrants who are married. First, Filipino females have a positive attitude toward marriage with a foreign male. Most immigrants are from the rural parts of their country, and their families tend to rely on their daughters more than their sons. Therefore, they decide to marry Korean males and immigrate in order to support their families. However many of them do not have enough information about Korea. Second, Philippine's family system is of bilateral kinship, and traditionally, men and women are treated equally. Therefore, Filipino females tend to be well-educated, outgoing, and vibrant. Thus, they can create an active role in married life for themselves and support their family members. Lastly, based on videos and class materials on the topic of domestic violence that are used in the pre-educational programs for females planning to immigrate to Korea, the content of the program is to be revised.

Universities are looking for various methods to enhance educational competence level suitable for the rapidly changing social environment. This study suggests a method to promote academic and educational achievements by reducing drop-out rate from their majors through implementation of pre-survey of satisfaction that revised and complemented survey items. To supplement the CQI method implemented after a general satisfaction survey, a pre-survey of satisfaction was carried out. To consolidate students' competences, this study made prediction and analysis of data with more importance possible using the Random Forest of the machine learning technique that can be applied to AI Medici platform, whose design is underway. By pre-processing the pre-survey of satisfaction, the students information enrolled in classes were defined as an explanatory variable, and they were classified, and a model was created and learning was conducted. For the experimental environment, the algorithms and sklearn library related in Jupyter notebook 3.7.7, Python 3.7 were used together. This study carried out a comparative analysis of change in educational satisfaction survey, carried out after classes, and trends in the drop-out students by reflecting the results of the suggested method in the classes.

This study aims to investigate the perception of pre-service early childhood teachers regarding play-oriented education through metaphorical analysis, in order to comprehend its meaning that pre-service early childhood teachers perceive. A questionnaire was used, which asked the participants to express play metaphorically and provide reasons for their choices. The collected data were analyzed using a systematic metaphorical analysis approach. The results revealed that the metaphorical expressions of pre-service early childhood teachers regarding play-oriented education were categorized as instructional methods being the most prominent, followed by environment, enjoyment/happiness, autonomy, growth and development, interactive relationships, child-directedness, the essence of life, interest, creativity, potential, variability, everyday life, ambiguity of beginnings and endings, naturalness, and others. Based on these findings, it is expected that one can attain insights regarding the methods of training pre-service early childhood teachers on how to implement play-centered education in the revised Nuri curriculum.

Osmolarity of culture media is one of the most important factors affecting in vitro development. This study was conducted to investigate the DNA methylation status of Pre-1 and satellite sequence in pig nuclear transfer (pNT) embryos produced under different osmolarity culture conditions. Control group of pNT embryos was cultured in PZM-3 for six days. Other two treatment groups of pNT embryos were cultured in modified PZM-3 with 138 mM NaG or 0.05M sucrose (mPZM-3, 320 mOsmol) for two days, and then cultured in PZM-3 (270 mOsmol) for four days. Previous our studies have reported that pNT embryos cultured in both hypertonic media showed significantly higher blastocyst formation rate than that of control. The DNA methylation status of the satellite sequences in blastocyst was characterized using bisulfite-sequencing technology. The satellite region had a similar methylation pattern of in vivo blastocyst among two culture groups excepting the control group. Each level of methylation is that the satellite DNA moderately methylated (43.10% of PZM-3; 56.12% of NaCl; 55.06% of sucrose; 60.00% of in vivo embryos). As a result of the sequence of PRE-1, CpG methylation pattern was similar to three groups, including in vivo group. In case of the satellite DNA region, the osmolarity conditions were affected CpG DNA methylation status while PRE-1 sequence was not affected CpG DNA methylation in pNT blastocyst stage. These results indicate that the modification of osmolarity in a culture media may influence to spatially change of DNA methylation of repetitive sequence for pNT embryo development.

This study intended to analyze pre-service elementary teachers' perceptions of teacher knowledge based on the Technological, Pedagogical, and Content Knowledge (TPACK) framework. Seventy-four pre-service elementary teachers who were enrolled at an University of Education located in mid-continent of Korea participated in a survey. Results of the survey was analyzed using Importance-Performance Analysis (IPA) method. It was found that perception of importance was significantly higher than that of performance at all seven domains of the TPACK. IPA matrix extracted from the survey indicates that Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK), and TPACK which are related to technology especially need to develop. Results of this study also show the necessity to support pre-service teachers so that they can have opportunities to develop and use technology-related knowledge and skills. This study especially implies that technological knowledge needs to be integrated with content and pedagogical knowledge when implementing curriculum and educational programs for pre-servie elementary teachers.
