Three decades after its establishment in 1946, Seoul National University was transferred to its current location in Gwan-ak District in accordance with the Seoul National University Integration Plan. In the 40 years since Seoul National University transferred to the Gwan-ak area, much quantitative and qualitative growth has taken place, and the university has grown into a world-class research institution. In this process, the campus was expanded externally and internally, and many changes have been made to the campus life bases and facilities which were planned at the beginning of the campus' construction. This study examines the expansion of the facilities at Seoul National University's Gwan-ak campus, as well as the expansion of the campus' boundaries. In addition, through quantitative analysis (Space Syntax), we predicted the location of campus life bases of the present multi-centralized campus and suggested a future developmental direction for the campus.

The purpose of this study is to identify rural research topics, differences in research topics over time, and key mediators through the analysis of academic research trends using topic modeling. This study analyzed a total of 1,183 articles published in the Journal of Rural Planning and Rural Society over a 23-year period (2000-2022). We categorized rural research topics into 30, examined the proportion of research in each topic, and identified major changes in research topics over time. We also identified key words that mediate between research topics. The study found that, first, rural research trends can be categorized into five types (resources and utilization, area/space, people, ecosystem/environment, and tourism), with area/space being the most studied. Subtopics include rural amenities, rural disappearance/village miniaturization, and rural landscape management. Second, the research topics for each period were different. In the first period(2003-2007), the main research topics were rural amenities and Agricultural production- based climate vulnerability assessment. In the second period(2008-2012), the main research topics were Rural extinction and village depopulation, and rural landscape management, and in the third period(2013-2017), the main research topics were rural sixth industrialization and rural ecotourism. In the fourth period(2018-2022), rural development planning and rural life services(life SOC) were the main research topics. The significance of this study is that it extends the existing method of analyzing research trends and provides basic data to enhance comprehensive insights and understanding of rural research.

The high-level nuclear waste repository is a deep geological disposal system exposed to complex environmental conditions such as high temperature, radiation, and ground-water due to handling spent nuclear fuel. Continuous exposure can lead to cracking and deterioration of the structure over time. On the other hand, the high-level nuclear waste repository requires an ultra-long life expectancy. Thus long-term structural health monitoring is essential. Various sensors such as an accelerometer, earth pressure gauge, and displacement meter can be used to monitor the health of a structure, and a piezoelectric sensor is generally used. Therefore, it is necessary to develop a highly durable sensor based on the durability assessment of the piezoelectric sensor. This study designed an accelerated life test for durability assessment and life prediction of the piezoelectric sensor. Based on the literature review, the number of accelerated stress levels for a single stress factor, and the number of samples for each level were selected. The failure mode and mechanism of the piezoelectric sensor that can occur in the environmental conditions of the high-level waste repository were analyzed. In addition, two methods were proposed to investigate the maximum harsh condition for the temperature stress factor. The reliable operating limit of the piezoelectric sensor was derived, and a reasonable accelerated stress level was set for the accelerated life test. The suggested methods contain economical and practical ideas and can be widely used in designing accelerated life tests of piezoelectric sensors.

Pesticides are widely sprayed by the growers in street trees and planting areas which include urban forests, community forests and city parks to control pests. Spraying pesticides not only affect the people who sprayed but also affect the unspecified citizens who's are exposed to pesticides sprayed trees by contact or inhalation. A few studies have been conducted to measure the amount of pesticides in forest area but no studies have been conducted to measure the pesticide amount in tree in public living space. So, in our study, we investigated the amount of pesticides in cotton gloves, in leaf residue, and respiratory exposure for a certain period of time after applying Fenitrothion EC to Korean boxweed tree (Buxus Koreana) to know the safety time of pesticides after spraying. We found that, up to 4d, there was no significant difference of the amount of Fenitrothion on leaves. But the amount of pesticides on gloves was significantly higher on 1h ($510.1{\mu}g$) and 24h ($405.4{\mu}g$) than 48h ($45.0{\mu}g$) after spraying. The amount of pesticides on inhalation was also significantly higher in 1 h ($0.2{\mu}g$) and 24 h ($0.1{\mu}g$) than 48 h after spraying. After 48h, we did not find pesticides amount in inhalation. Thus, we was considered necessary to pay attention to 48h after spraying of pesticide Fenitrothion.

The purpose of this study is to develop and implement a process-based evaluation program with the theme of school space design in the housing area of the middle school home economics. In order to achieve For thispurpose, a process-based evaluation program based on the theme of school space design was developed following the ADDIE instructional design model, and the program was executed to a total of 93 students. A questionnaire survey and in-depth interview were conducted for the evaluation of the program. The results of this study are as follows. First, based on the results of a 2015-Revised Curriculum analysis, a school space design program evaluation plan was established, and two evaluation tasks were developed. Accordingly, scoring criteria were prepared and 8 evaluation materials for students and 2 evaluation materials for teachers were developed. A total of 9 sessions were developed for teaching and learning activities and evaluation-linked operation procedures to perform evaluation tasks. As a result of an expert validity test for the program, all items were verified to be appropriate in content validity and content composition with an average of 3.6 to 4 points (4 points). Second, after conducting the school space design program, a survey on students were conducted, and as a result, all three areas of school space design class, process-based evaluation, interest scored high in average scores of 4.12 to 4.27 out of 5. According to the survey and interview results, the program provided new learning opportunities for school space design, the students were able to reach the suggested achievement goals, and the self-assessment, peer evaluation and teacher feedback positively affected the students during the learning process so that they could reflect on their learning and actively participate in the subsequent learning activity. This study has a limitation in generalizability in that the program was conducted on a limited number of students, and future studies are expected to expand the scope in terms of research participants, evaluation criteria, and school space design classes. This study laid the foundation for theory and practice by developing and implementing a process-based evaluation program for home economics education, and it has contribution in that it suggested the possibility that teachers and students can take the initiatives in school space design, focusing on the housing content elements of home economics.
