The purpose of the study is to examine the impact of ESG activities on brand value by linking the effectiveness of ESG activities to marketing, the most core part of a company. This study conducted an empirical analysis targeting companies listed on KOSPI and KOSDAQ from 2016 to 2022. Looking at the empirical analysis results of this study, first, in the individual analysis of ESG activities, it was confirmed that E (Environment) and G (Governance) have a significant positive influence on brand value. Second, in the environmental field, stakeholder response had a significant positive relationship with brand value, and in the governance field, the board of directors had a significant positive relationship with brand value. Through this study, we can provide logical evidence proving that ESG activities are important activities that must be carried out in advance to increase brand value. Among ESG activities, it was found that stakeholder response activities in the environmental field and board-related matters in the governance field play an important role in increasing brand value. It is also expected that it will serve as a catalyst for research on the importance of ESG activities in the marketing field.

This article reviews the recent activities of field testing and application of superconducting fault current limiters (SFCL) based on high-temperature superconductors (HTS). The review particularly focuses on the trends in the field tests in terms of the technical aspects and commercial activities of the SFCLs. Stimulated by the discovery of HTS, numerous research and development activities have been conducted worldwide for SFCLs operating from distribution voltages to transmission voltages. Different types of SFCLs have been developed and field-tested. Consequently, more than 20 field tests and applications have been performed on real grids worldwide while supplying electric power to the customers. These field tests have not only provided the track records of the operation experiences including the problems and maintenance during operation, but also proved their current limiting capabilities against real faults, rendering this new technology highly viable. Through these activities, the following trends in the status of field testing and application are observed. Resistive-type SFCLs with HTS-coated conductors were dominantly used in the most recent field tests. This implies that the resistive type is technically more mature than the other types. Bus-bar coupling and transformer feeders were the major application locations. It is of importance that most of the field applications were conducted as R&D projects. A relevant change from the R&D stage to the application stage is shown as recently deployed SFCLs are expected to be under long-term operation and commercial service. Here, we review the installation of these SFCLs by substation. This review also discusses the recent activities for their commercial applications.

We explored the possibilities of science field experience in Jongmyo Shrine in this study. To understand the educational value of self-leading science activities in Jongmyo Shrine, one of the World Heritage, we developed science program and applied it to the elementary students participating in a gifted education center. We collected and analyzed various data of opinionnaire survey before and after the program, field activity sheets, field observation, and individual- and group interview. The results showed the lack of students' spatial ability and proposed educational interests in science education. Also, a lot of students felt the difficulty in applying school science knowledge into the real life context. Students found the meaning of science learning through cooperative activities in the historically meaningful place. A proper use of smart device in science field experience was recommended. We found that activities with too much smart device might impede various scientific process skills.

This study is the field of mathematics education on the assumption that they can extend outside the classroom. Recent mathematics education is increasing the importance of field experience and various activities based on real-life math education. Thus, it is necessary to consider this situation in pre-service teacher's education. The purpose of this study is to apply the 'Mathematics Field Trips Activities' in the pre-mathematics teacher education. So the specific case of 'Mathematics Field Trips Activities' was analyzed. Mathematics teachers conducted preliminary exploration activities on the historical cultural property which were effective in the following four aspects. First, cognitive effects and second, definitive effect. Third, cultural-mathematical effect. Fourth, the effect on improving math class. Finally they were summarized and divided into classes target content knowledge and teaching knowledge both sides. As a result, the 'Mathematics Field Trips Activities' were found to have significant effects on pre-service math teacher. Finally, ongoing research is needed to settle into a new teaching and learning methods.

The purpose of this study is to analyze field trip activities in the elementary school science textbook developed under the 7th national curriculum. The results indicated there was an average of 4.25 field trip activities each semester presented in the textbook from the 3rd to 6th grade, mostly related to earth science and biology. The places for field trips were limited to in-school environment and natural sites in communities, and mostly purported to gain understanding of rudimentary concepts. Field trip activities were intended to facilitate science knowledge and understanding in order to integrate with the textbook content rather than offering students simple one-time activities. Most activities in the textbook guided students step by step. The starting or follow-up activities in the fields trips and reminder for cautions were not clearly presented. In order for the field trips to integrate with the content of the curriculum in the text book, they have to be presented in the textbook systematically. It is also imperative to find out various fold trip places related to the content in the curriculum, develop efficient activities dealing with science at the appropriate level for students and increasing interests in science and its teaming.

The purpose of this study is to reveal the insights that teachers has learned through developing preschooler's classroom into field-trip-oriented ones with role play areas. The data of this study was collected from participatory observation and in-depth interviews, which included videos, photos, teachers' journal, descriptive questionnaire, and interview records. The whole process of organizing role-play oriented class was composed of four steps: activities before the trip, activities on-the-spot, activities after the trip, and its evaluation. Firstly, activities before the trip were making the lists of questions, deciding children who ask the questions, making rules on the trip, understanding the purpose of the trip. Secondly, on-the-spot activities included having a tour of the place and asking the questions. Thirdly, activities after the trip was constructing the classroom into small real world with various sections. This required the teachers to reflect the field trips, make plans how to construct, prepare for the data, and furnish the classroom with role-play areas. In the process of furnishing the classroom with small real world, the field trips played a big role as the learning opportunities for language development, and keeping public rules.

Fire scene is mostly destroyed by the flames but fire fighter's fire suppression and rescue activities also destroys a substantail portion. Structures and furnitures which has already become weaken can be easily damaged. Or when structures built up by moving to another location, it's very hard to restore the original state. Also if it is restored, the object has no evidence that it has existed. In all scenes, the scene can't be preserved when quick extinguishment, rescue activities and preventation of fire spread is needed. On this paper, it reviewed the notes about the possibility of field damage by fire suppression and rescue squad's activities. Also it has reviewed the notes how to minimize the field damage by putting out fires and rescue activities by observing the precautions. The reviewed information will help to make guidelines for preserving the scene. By this, it is expected to make a field study exactly by collecting more valid evidence.

The field is a good learning environment that offers many opportunities. Status of conducting field trip in the middle and high school was investigated As a result, there was few teachers who disagree that a course in science should include learning in the field. Yet, on practical side, teachers who used to conduct the field trip over once a year in science class appeared to be about 23% only. Most of schools conducting field trips hadn't well-planned program for instructional activities. Many of teachers appealed that they should not get release time for conducting an extended field experiences, and that they could not obtained good information in relation to the contents, the methods and strategies of field activities. It says that a good field trip needs administrative and financial surport, many informations, and the teacher's exertion.
