학교폭력의 교육적 대안

서정기(Jungki Seo) 한국배움학회 2012 배움학 연구 Vol.4 No.1

교육 공동체로서 학교는 학생들의 바른 인격적 성장을 위한 공간이다. 학교는 학생들의 부적응 및 문제행동을 선도하고, 교육하는 책임을 가진다. 이를 위한 학교의 생활교육은 응보적(retributive) 패러다임에 입각해 이루어져 왔다. 그러나 이러한 처벌 중심의 생활교육이 교육문제의 실제적인 개선과 교육적 효과를 가지고 오지 못하고 처벌을 둘러싼 학교 구성원들의 갈등이 심화되면서 새로운 대안이 요구된다. 이에 잘못에 대해 상응하는 처벌을 부여하는 것에 초점을 둔 응보적 정의에 입각한 생활교육 대신에 공동체 구성원과 당사자가 함께 참여해 잘못으로 인한 폐해를 바로잡고 공동체와 개인의 피해회복에 초점을 두는 회복적 패러다임에 입각한 생활교육이 실천되고 있다. 이는 당사자의 참여를 통한 피해회복과 이를 위한 구체적 노력을 중시한다. 이러한 회복적 생활교육은 학생의 참여를 통해 자신의 잘못을 깨닫고 책임을 배우는 기회를 제공한다. 그리고 이러한 회복적 생활교육의 실천은 관리와 통제를 넘어 학생들 스스로가 자기훈육(self-discipline)의 능력을 가지는 배움의 기회를 제공할 것이다. Schools, as a learning community are supposed to be a place for educational growth of students. So, it is responsible of education for self-discipline that make them understand their wrong doings and behaviors and help make those right. Retributive way of discipline has been applied to for it. However, retributive disciplining of the matter that concludes a case through punishment does not meet the students' educational needs, and neither achieves the educational goal to support normal school life among students. It rather makes conflict worse among school members. Schools should not only resolve conflicts but also correct students' problem behaviors, and build safe educational environments through educational growth and development. For this, paradigm of discipline needs to be changed from retributive approach which focus on giving right punishment to restorative way which focus on making harms made by wrongdoings right. It will help for students face their own wrongdoing and understand responsibility of it, instead of blaming to authority and punishment given to them. In addition, it also will prepare more learning opportunities for self-discipline.

Many researches and policies have been carried out for saving energy in buildings. However, there are a few studies of thermal characteristics of wood-based materials that have been widely used as structural materials and finishing materials in buildings. In this study, thermal bridging areas were found to investigate thermal performance of residential building using non wood-based materials and wood-based materials. And heat transfer analysis of 16 case studies according to composition of structural materials and finishing materials was conducted. Also in this experiment, Physibel Trisco was used as the heat transfer analysis simulation tool, which conforms to the calculation method of ISO 10211. Analytical modeling was also carried out according to the ISO 10211, and the boundary temperature conditions were set at room temperature 20℃ and outdoor temperature -11.3℃ (Seoul standard) according to the energy saving design standard in South Korea. Applied structures are classified according to the cases of concrete structure with non wood-based finishing materials, concrete structure with wood-based finishing materials and wood structure. Analyzed building elements were divided into a wall, a roof, an interlayer floor and a bottom floor. As a result, it can be confirmed that the thermal bridge of the concrete structure and wood structure were caused by the geometrical and material causes. In addition, the structural thermal bridge was caused in the discontinuity of the insulation in the concrete structure. Also it was confirmed that the linear heat transfer coefficient of the wall decreases when the wood-based materials are applied to the concrete structure.

The purpose of this study was to improve the thermal conductivity in floor base material (HDF, High Density Fiberboard). By adding 0.5~ 4% graphite into the HDF, we can improve the thermal conductivity but the internal bond of the HDF was reduced up to 50% in relation to the quantity of graphite added. And to improve IB(Internal Bonding), we have tried to increase resin content and press time but there were no improvement. But increasing melamine content from 12% to 20%, we have noticed that the IB has improved to the required level. Since graphite is reducing IB and making the HDF color darker, it is practical to reduce the graphite down to 0.5% and increasing melamine up to 20% to get 8.3% improvement on thermal conductivity.

Energy consumption for thermal comfort in buildings has grown a lot in few years because of increasing users demand for comfort conditions and the associated market penetration of more heating systems. In Korea, radiant floor heating system has been used in residential buildings traditionally. This type of residential buildings consume approximately 55% of the total residential building energy consumption in heating. Therefore, any decrease in heating energy consumption will significantly reduced total residential building energy consumption. Thermal energy storage is a useful tool for improving energy efficiency and increasing energy savings. In latent heat thermal energy storage systems, energy is stored during melting and recovered during freezing of a phase change material. In latent heat thermal energy storage systems (LHTES), energy is stored during melting and recovered during freezing of a phase change material (PCM). This study aimed to prepare the composite PCMs with low mass fraction of exfoliated graphite nanoplatelets (xGnP) to obtain applicable PCMs as building materials and to investigate the effect of xGnP addition on thermal conductivity, melting temperature and latent heat capacity of PCMs, in order to satisfy thermal comfort of residential building using radiant floor heating system with energy conservation.

학교현장에서 교사들이 생활지도로 어려움을 겪고 있는 변화된 환경 속에서 2010년 경기도교육청에 의해 정책적으로 추진된 회복적 생활교육이 주목받고 있다. 본 연구는 회복적 생활교육이 정책적으로 추진되기 이전부터 이를 자발적으로 실천하고 있었던 교사들의 경험에 주목하여, 회복적 생활교육을 통해 드러난 오늘날의 교사됨의 의미를 탐색하고자 하였다. 이를 위해 내러티브 탐구 방법을 사용하였으며, 세 명의 교사들과 2015년 1월부터 3월까지 약 3개월 동안 심층 면담한 결과를 기록한 전사본, 교사들의 실천 일지, 연구자 일지를 통해 자료를 수집하였다. 연구 결과에 따르면, 세 교사는 회복적 생활교육을 계기로 자신들의 교사됨의 의미를 세 가지 측면에서 새롭게 깨닫고 성장해 나가는 모습을 보여주었다. 첫째, 교사들은 교육으로부터 소외되지 않고 교육자 본연의 역할을 수행하길 희망하고 있었다. 둘째, 교육공동체내에서 학생들과 관계 맺고 가르침을 주는 존재로 살아가길 원하고 있었다. 셋째, 동료교사들과의 관계 속에서 소통하고 연대하며 협력적 관계를 맺고자 하였다. 이처럼 회복적 생활교육 실천 경험을 통해 살펴본 교사들의 내러티브는 교육공동체 회복을 통해서만 학생 생활지도가 가능해질 수 있음을 시사한다. The application of Restorative Practices (RP) in schools has begun to receive great attention as an alternative method of school discipline to punitive discipline. The purpose of this study is to examine teachers` personal experiences, change, and growth from RP in schools and to explore the development of teacher identity from their field experience. Data were collected through three months of in-depth interviews, teachers` notes, and researchers` field notes. The analysis of the teachers` narratives is presented based on the following three main themes - (a) teachers` hope to conduct faithful role as an educator, grounded in restorative values, (b) teachers` desire to establish authentic relationships with their students, and (c) teachers` need to engage with positive relationships with their fellow teachers and to contribute to changing the culture of the school. Findings from our analysis suggest that RP are highly helpful in building and maintaining respectful social relationships in schools, and that school discipline is practical only when based on restoring the education community.

In recent years, the researches on low energy building materials are very active with growing interests on eco friendly building. In wooden flooring sector, there are also strong interests in improving the thermal conductivity of the under floor heating system. In order to improve the thermal conductivity in laminate flooring, we have achieved a positive result by adding the exfoliated graphite into the floor base materials (HDF, High Density Fiberboard). By adding 0.6~4% of graphite into the HDF, we can improve the thermal conductivity, but the internal bond of the HDF was reduced up to 60% in relation to the quantity of graphite added. Moreover, to improve IB (Internal Bonding), we tried to increase the resin content and press time, but there is no improvement. However, we have noticed that the IB was improved to the required level when melamine content was increased from 12% to 20%. Since the graphite makes IB reduce and the HDF color be darker, it is practical to reduce the graphite down to 0.6% and to increase melamine the content up to 20% to get 8.3% of improvement the thermal conductivity.
