초등학생의 지각된 부모 양육태도와 스트레스 대처행동과의 관계에서 성격강점의 조절효과: 절제 및 용기 관련 성격강점을 중심으로

강동화 ( Kang Dong Hwa ),김광수 ( Kim Kwang Soo ) 서울교육대학교 초등교육연구원 2021 한국초등교육 Vol.32 No.4

본 연구는 초등학생의 지각된 부모 양육태도와 스트레스 대처행동(공격적, 소극ㆍ회피적)간의 관계에서 절제 및 용기 관련 성격강점의 조절효과를 확인하는데 그 목적이 있으며, 이를 위해 서울특별시 및 세종특별자치시 소재 초등학교 5,6학년 학생 401명의 설문지를 수집하였다. 수집된 설문지의 검사 결과를 바탕으로 측정변인간의 관계 및 특징을 파악하기 위해서 상관분석을 실시하였고, 지각된 부모양육태도와 스트레스 대처행동 간의 관계를 절제 및 용기 관련 성격강점이 조절하는지를 위계적 회귀분석을 통해 확인하였다. 분석 결과를 살펴보면 첫째, 절제 관련 성격강점과 소극·회피적 대처행동 간의 관계를 제외한 모든 변인들 사이에 유의미한 상관관계가 있었다. 둘째, 지각된 부모양육태도와 공격적 대처행동의 관계에서 절제 및 용기 관련 성격강점은 유의미한 조절효과가 없는 것으로 나타났으며, 지각된 부모양육태도와 소극·회피적 대처행동의 관계에서 절제 및 용기 관련 성격강점 중 용기 관련 성격강점이 유의미한 조절효과가 있는 것으로 나타났다. 이는 부모의 부정적 양육태도가 아동의 소극·회피적 대처행동에 미치는 부정적 영향력을 완화시키는데 아동의 성격강점 중 용기 관련 성격강점의 역할이 중요함을 의미한다. 본 연구의 결과는 초등학교 고학년 학생의 공격적이고 소극·회피적인 대처행동 개선을 위해서 절제 및 용기 관련 성격강점을 활용할 필요가 있으며, 특히 소극·회피적 대처행동 개선에는 용기 관련 성격강점(용감성, 끈기, 진실성, 활력)을 개발하는 훈련이 효과적인 개입이 될 수 있음을 시사한다. 본 연구결과는 부정적 양육환경 속에서 자라온 아동들이 이로 인한 부정적 영향을 이겨내고 스트레스 대처행동을 개선하는데 필요한 이론적 근거를 제시하며, 초등학생의 공격적 대처행동 및 소극·회피적 대처행동 개선을 위한 기초 자료를 제공하고 있다. One of the purposes of this study is to identify how the Perceived Parenting Attitude, Character Strengths(temperance, courage), Stress-Coping Behaviors(aggressive, passive-avoidant) are related. Another objective is to examine the moderating effects of Character Strengths(temperance, courage) between perceived parenting attitude and stress-coping behaviors of elementary school students. This research has chosen students in grade 5 and 6 in Seoul and Sejong. The research used questionnaire method to measure the children’s perceived parenting attitude, character strengths, stress-coping behaviors. Total of 409 people answered, and 401 people who was suitable for the research was finally chosen. The results of the study are as follows: First, there was significant negative relationship between perceived parenting attitude, aggressive coping bebavior and passive-avoidant coping behavior. There was significant positive relationship between perceived parenting attitude, temperance and courage. There was significant negative relationship between temperance and aggressive coping behavior and between courage, aggressive coping bebavior and passive-avoidant coping behavior. Second, courage moderated the relations between perceived parenting attitude and passive-avoidant coping behavior. Those results showed that Character Strengths(temperance, courage) are negatively related to aggressive coping bebavior and passive-avoidant coping behavior and it can moderate the relations between perceived parenting attitude and passive-avoidant coping behavior. Then this researcher suggests that training programs and counseling for aggressive coping behavior and passive-avoidant coping behavior focused on Character Strengths are needed.

A number of maritime accidents such as collisions and grounding by ships of all sizes, such as fishing boats and passenger ships, can occur when sailing within narrow channels. In accordance with the Rule 9 of Convention on the International Regulations for Preventing Collision sat Sea 1972(hereinafter the “COLREGs”) and its domestic legislation, Article 67 of the Maritime Safety Act, the navigation rules in a narrow channel shall be applied, such as a vessel proceeding along the course of a narrow channel or fairway shall keep as near to the outer limit of the channel or fairway on her starboard side as long as it is safe to do so. Article 67 of the Maritime Safety Act in Korea also stipulates the same contents as in the COLREGs regarding navigation rules in a narrow channel. However, given COLREGs and Maritime Safety Act do not stipulate definitions and criteria of “a narrow channel”, it is not clear how to define and to set criteria for “a narrow channel”. In this regard, in relation to the recent collision case between the car ferry and the fishing boat(hereinafter “this incident”), Korean Maritime Safety Tribunal (hereinafter the “KMST”) decided that the waterway where this incident happened is not a narrow channel. However, on the other hand, High Court and Supreme Court(hereinafter the “Court”) made a judgement that it is a narrow channel. In other words, decisions handled down by the KMST and the Court were different on crews’ negligence of the both vessels in this incident based on whether the waterway this incident occured falls under a narrow channel or not. A criminal case against the master of the car ferry was also proceeded in respect of this incident. As a result of the different decisions made by the KMST and the Court, higher criminal court has turned over the judgments of the lower criminal court. Even before this incident, there were some decisions made by KMST and Korean courts on a narrow channel, but the certain criterion and definition for a narrow channel is not established yet. Under the circumstances, this study aims to review the issues in relation to the navigation rules in a narrow channel, the apportionment of liability and negligence on the collision in a narrow channel, the effect of the decision of KMST on civil and criminal proceedings and the necessity of maritime court by reviewing Supreme Court Decision 2020.1.16. Docket No. 2019du54092 and Daejeon High Court Decision 2019.9.18. Docket No. 2019nu10342, the decisions of the KMST and the criminal courts, etc.

재실자 발생 이산화탄소 가스를 활용한 주거건물의 공기교환율 추정

The objective of this study is to investigate methodology of estimating air exchange rates using occupant-generated carbon dioxide (CO₂) gas in residential buildings. The method uses build-up and decay of indoor CO₂ concentration data assuming constant air exchange rate and constant CO₂ generation rates by occupants. Field experiment data measured in residential units for 7 days were employed to investigate the CO₂ method and compare the results of air exchange rates estimated by CO₂ method with those by SF6 (sulfur hexafluoride) and PFT (perfluorocarbon tracer). It is found that the daily patterns of CO₂ concentration during the test period are not repeated. Also, it was suggested that the decay curve of CO₂ concentration was more feasible in estimating air exchange rates, due to the insufficient occupant schedule data provided during the experiment. The air exchange rates estimated using three methods showed different results. The CO₂ method using decay curve resulted in similar distribution of the estimated air exchange rates with the values by PFT method. This finding suggests that the occupant-generated CO₂ method can be one of practical methods to estimate air exchange rates for residential units.

주거건물의 실내외 미세먼지 측정에 의한 실외 미세먼지의 실내 영향도 평가 기초연구

Indoor particle concentration is partly affected by penetration of outdoor particle through building envelopes. Therefore, understanding particle penetration phenomenon in buildings is crucial for evaluation of indoor air pollution caused by fine particle. The objective of the present work is to investigate the impact of outdoor dust on indoor dust level in residential buildings. Field measurements to examine concentration ratio between indoor and outdoor particles (I/O ratio) were carried out in a residential housing unit located in Daegu, Korea. The I/O ratio of size-resolved particle, ranging from 0.3μm to 10.0μm, was compared to examine the impact of outdoor particle on indoors. The results showed that the I/O ratio of small particle (less than 1.0μm) is higher than that of large particle(larger than 3.0μm). The study also showed that the I/O ratio in the day with higher infiltration was higher in the day with lower infiltration, indicating that the building infiltration rate is related to particle penetration
