Recently, concerns about conserving proper size of urban green spaces and accessibility are increasing, regarding it as a solution to diverse urban environmental problems including pollution, ecosystem deterioration, urban climate change. Artificial ground greening such as green roofs is regarded as the only alternative that can conserve green spaces which are impossible to be secured on the ground. However, green roofs are not popularized yet and levels are very low in provincial cities despite of related technology development and support systems of related agencies. Based on the background, this study tries to present a theoretical basis of methods for green roofs, conducting green roof simulations Finally, it aims to offer base data which help establish policy direction for activation of green roof technology. As a result of a simulation for verifying temperature reduction effect, it was possible to affirm effect of a plot that green roofs applied. Especially, it was revealed that a green roof method using ground covers such as mixed planting was the most effective way to reduce temperature. Based on precise analysis of the users, actual study for activation of green roofs should be developed in the future, by presenting a standard model for experiments and obtaining information about examples of green roofs on private houses.

교사의 비언어적 의사소통 행동이 학생 개인 특성에 따라 수업에 미치는 영향

이춘우(Chun-Woo Lee),김선연(Sun-Yun Kim) 한국엔터테인먼트산업학회 2016 한국엔터테인먼트산업학회논문지 Vol.10 No.5

본 연구는 교사의 비언어적 의사소통 행동(신체언어, 공간언어, 유사언어, 인공언어)이 학생의 개인 특성(성별, 학교급, 학업성취 수준)에 따라 수업에 영향을 미치는지를 연구하고자 하였다. 이를 위해 중·고등학교 학생을 대상으로 설문지를 통한 조사연구를 실시하였다. 개인 특성에 따른 주요 연구결과는 첫째, 성별에 따라 비언어적 의사소통 행동의 수업에 대한 영향력은 다르게 나타났는데, 여학생이 남학생 보다 모든 유형에서 그 영향력이 큰 것으로 나타났다. 둘째, 학교급에 따라서도 비언어적 의사소통 행동의 수업에 대한 영향력은 다르게 나타났다. 신체언어와 유사언어에서는 고등학생이, 인공언어에서는 중학생이 더 크게 영향을 받았다. 셋째, 학업성취 수준에 따라서도 비언어적 의사소통 행동의 수업에 대한 영향력은 달랐는데, 인공언어를 제외한 모든 유형에서 중·상위권 학생들이 하위권 학생들보다 더 큰 영향력이 있는 것으로 나타났다. 이에 대한 가능성 있는 이유로서 남녀간 성차에 따른 정서와 감정의 차이, 중·고등학생의 수업과 학습에 대한 상이한 스트레스, 중·상위권 학생과 하위권 학생들의 수업과 학습에 대한 차이점, 그리고 비언어적 의사소통 행동들의 수업과 학습의 관련성이 논의되었다. This study was to empirically analyze the effects of teachers’ non-verbal communication behaviors(kinesics, proxemics, paralanguage, artifacts) on instruction depending on students’ individual characters (gender, school level, & achievement level). For this purpose, the study conducted survey research, subjects of which were middle and high school students. Major findings regarding the individual characters are as follows: First, the study showed that the effects of nonverbal communication behaviors on instruction were different according to gender difference, showing that female students were influenced more than male students in all types of nonverbal communication behaviors. Second, the study revealed that there were significantly different between school levels in the effects of nonverbal communication behaviors on instruction, showing that high school students were influenced more than middle school ones in kinesics and paralanguage, while middle school students were influenced more than high school ones in artifacts. Third, the study found that the effects of nonverbal communication behaviors on instruction differed from their achievement levels, showing that upper and mid-level students were influenced more than lower level ones in kinesics, proxemics, and paralanguage. The study discussed the plausible reasons, including the gender differences in emotion and affection, different stress in learning and instruction between middle and high school students, and the relationship between learning/instruction and nonverbal communication behaviors.

정보통신기술(ICT)의 활용은 통일교육에 다양한 가능성을 제공해줄 수 있다. 학교통일교육의 심리적 기초는 흥미의 원리이다. 철학적 기초는 정치적 목적과 교육적 목적의 상관관계에 있다. 해석학적 기초는 사회․문화적 통합이다. 사이버 세대들에게 합리적인 통일 의식을 교육시키는 것이 우리의 시대적 사명이며 이를 좀 더 효율적으로 수행하려면 의미있는 접근이 중요하다. 첫째, 교육매체적 접근이다. 사이버 매체의 특성에 맞는 다양한 접근이 필요하다. 멀티미디어, 하이퍼미디어, 인터넷을 활용하여 영상세대에게 효과적으로 접근할 수 있어야 할 것이다. 둘째, 교육내용적 접근이다. 통일교육과 관련된 다양하고 풍부하며 직접적으로 활용할 수 있는 데이터베이스의 연계와 구축이 무엇보다 시급하다. 셋째, 교육방법적 접근이다. 정보화 시대에 알맞은 교수-학습 방법을 활용해야 한다. 통일교육의 ICT 활용방안도 다양한 지원과 함께 현장 적용이 이루어질 때 그 교육적 효과도 높아질 수 있을 것이다. The purpose of this study is to examine a useful ICT application model for unification education in school. For this purpose, the study surveyed various ICT method for unification education in school. They are ①: mental ②: philosophical ③: analytic foundation of unification education in school. The first is the principle of interest. The second is the true goal of unification education in school. The third is social & cultural unification. They are ①: educational media ②: educational contents ③: educational methods of unification education in school. The first is the educational application plan of multimedia & hypermedia. These media are effective to cyber generation The second is the application of network contents of SUE. We need various & direct database of unification education in school. The third is various ICT application methods of unification education in school. We must develope the adequate ICT teaching & learning methods of unification education in school. In conclusion, we must build the powerful student with unification skill. This will make them self realization. Furthermore it raise the national unification power. For this purpose we should do our best in school unification education for national unification of south & north Korea.

Trawl fishing is a fishing method in which a large, motorized trawler tows a bag-shaped net to catch fish living at the bottom or middle layers. For a trawl gear, it is of utmost importance to select the gear size and towing speed suitable for the effective horsepower (EHP) of the trawler in the design stage. In general, the power required to move an object is proportional to the product of the object speed and resistance; therefore, there are various choices for the gear resistance and towing speed given the effective horsepower of the trawler. However, there have been few studies on the gear design of an appropriate scale for the towing speed given the effective horsepower of the trawler. In this study, the resistance and shape of three types of midwater trawl gears were analyzed using SimuTrawl, a computer simulation tool. In addition, the relationship between the propulsion force and speed of the ship was clarified when the size and effective horsepower of the trawler were determined. Finally, we suggested the relationship between the towing speed and the resistance of the gear when the trawler towed the net was investigated, and a specific method of selecting the gear size according to the towing speed.

Recently, concerns about conserving proper size of urban green spaces and accessibility are increasing, regarding it as a solution to diverse urban environmental problems including pollution, ecosystem deterioration, urban climate change. Artificial ground greening such as green roofs is regarded as the only alternative that can conserve green spaces which are impossible to be secured on the ground. However, green roofs are not popularized yet and levels are very low in provincial cities despite of related technology development and support systems of related agencies. Based on the background, this study tries to present a theoretical basis of methods for green roofs, collecting ideas about problems and improving measures from green roof users. Finally, it aims to offer base data which help establish policy direction for activation of green roof technology. Results of a survey on public awareness, using status, and improving measures of green roofs are as follows: First of all, publicity activities which aim to offer information for citizens must be conducted to activate green roofs. Second, it is needed to establish solutions and to offer technology and management information because green roof users recognize problems concerning load, waterproofing, and garbage disposal in common. Third, green roofs should be applied to public agencies or buildings on a trial basis. For private houses, it is required to build green roofs first by accepting applications. Fourth, legal and institutional preparation for support systems is needed because citizens' biggest considerations are basic subjects on materials and expense of green roofs. Activation methods for green roofs based on this study are as follows: First, it is a priority to readjust systems related to green roofs. Second, citizens' active and voluntary participation must be attained. Third, it is required to establish detailed promotion procedures which aim at actual conduct and to maintain an expert department which is able to manage and control the establishment. After conduct, continuous aftercare stages are also needed.
