This study aims to propose some alternatives in architectural planning for reducing the class size of elementary, middle and high schools. In order to achieve above purpose, I discuss the current status of class size, the relationship between class size and educational outputs and the obstacles in realizing the optimum class size of elementary, middle and high schools during the past 40 years. Finally, the paper proposes 8 alternatives in reducing the class size, which can be considered during the early stage of school planning.

School violence has long been recognized as a social problem, and various efforts have been made to prevent it. In this study, we propose a system that can prevent school violence by analyzing data on the frequency of conversations between students, friendship and preference to be in the same group. This data was quantified using a Likert scale questionnaire, and also grouped into the appropriate number of clusters using the K-means algorithm. Additionally, the homeroom teacher observed the frequency and nature of conversations between students, and targeted specific individuals or groups for counseling and intervention, with the aim of reducing school violence. Data analysis revealed that the teachers' qualitative observations were consistent with the quantified data based on student questionnaires, and therefore applicable as quantitative data towards the identification and understanding of student relationships within the classroom. The study has potential limitations. The data used is subjective and based on peer evaluations which can be inconsistent as the students may use different criteria to evaluate one another. It is expected that this study will help homeroom teachers in their efforts to prevent school violence by understanding the relationships between students within the classroom.

Since the number of student is regarded as the fundamental basis to calculate the future allocation of employed teachers, it needs to be systematically estimated based on statistical data. In order to achieve this purpose, the number of high school students is projected following the assumption that the teacher-student ratio of Korea should be adjusted to the level of OECD to improve the quality of education. Hence, this paper introduced the projection methods by time series model. To predict the number of high school students and error estimation, various models were adopted.

The results of research and analysis are as follows: First, there were 108 types of change patterns in the number of elementary school students. Second, based on the similarity of 108 types of change patterns in the number of students, a type system diagram was presented. Third, in the case of a total of 18 types of change patterns in the number of students, the number of students decreased significantly due to the establishment of additional schools on top of the existing schools. The result of a a long-term survey and analysis on the trend of increase and decrease in the number of students across the country shows an urgent need todevelop policy tasks across the entire school accommodation plan, such as the establishment of differentiated schools suitable for regional characteristics, relocation, consolidation, reorganization of school districts, remodeling, and appropriatization projects.
