Urban cmmunity films have achieved the industrial modern society's idiosyncrasy Popular films have achieved the industrial growth through city as the completion of modernization. They also have represented the social meaning of urban space, and have expanded 'their political space' This filmic challenge showed diverse negative factors which were the poor's economical difficulties, the relative robbery of their education and job, and adhered class in city through developing the urban space with were hidden beyond modernity's splendor.

현대사회는 문화, 관습, 의식구조 등에 의해 소규모 아파트 및 원룸에서 개인 혹은 2 인 이상 거주하는 생활 방식으로 그 거주형태가 점차 변화하고 있다. 하지만 이런 유동인구가 늘어남에 따라 각자의 생활 속에서 서로의 사생활 침해가 빈번하게 일어나고 있으며, 우리 생활 속에 그대로 노출되어 있다. 또한, 사생활 문제뿐만 아니라 좁은 공간에서의 생활에 따라 좀 더 사생활이 보장되고 수납할 수 있는 공간이 필요하게 된다. 본 연구에서는 이런 문제점을 보완할 수 있는 방안으로서 아파트 및 원룸 거주공간에서 혼성 또는 동성, 2 인 이상이 거주하는 공간을 대상으로 수납공간의 효율성이 더해진 사생활 보호의 방안을 찾는 것을 목적으로 한다.

한반도 남동부지역에서 이루어진 활단층에 대한 일련의 연구들은 구조운도에 대한 관심을 불러 일으키고 우리나라가 안정지괴라는 생각에 변화를 일으키고 있다. 본고에서는 조선시대 한반도에서 발생한 지진 기록을 세계적으로 유례가 드물게 역사적 사실을 정확하게 기록한 조선왕조실록에서 확인하였다. 이 자료와 20세기에 이루어진 계기관측자료를 종합하여 지난 600년 간의 지진발생의 주기성과 공간분포를 검토하였다. 한반도 지진발생은 시.공간적으로 일정한 패턴이 있었으며, 대략 100-150년을 주기로 활성기와 잠복기를 반복하였다. 지진은 평안분지서안, 옥천변성대와 혼성구, 경상분지에서 높은 빈도로 발생하였다.

The relevance between organisms and their external environment covers everything including humans, natural and artificial surroundings, regarding which academic and scientific understanding has continued. Relevant elements established by inter-dependence between humans and environment and the unity of life should be translated from the perspective of a whole, not of unit elements or reduction. That is, a space is formed by its own program and assumes sustainable relevance based on interactions between internal and external spaces, not building an independent system. The present study aims to present the feasibility of a potential mutant space formed by invisible arenas between individuals and evolutionary space formation based on an ecological paradigm Accordingly, this study suggested that evolutionary attributes as the major power source of biological changes could verify the virtual multiplicity of a new space formation, and that the potential form generation of hybrid mutant space of emergence and infinite formative capability could be supported. The suggestions made here will hopefully contribute to extending applicability of evolutionary space generation in the field of space design. To derive the potential mutant forms from biological space, a preliminary study was conducted regarding the characteristics of evolutionary form generation. For the purpose of this study, three evolutionary perspectives of reproduction, mutation (variation) and selection were taken. First, the theory of evolution was defined and characterized. Also, the relevance between the characteristics generated and hybrid mutant space was analyzed to consider relevant characteristics. The present study helped to understand that the hybrid mutant space had an evolutionary space structure based on a biological paradigm. It was also found that the mutant space structure built by mutant polymorphism assumed a systematic correlation between space and environment.

A sound field simulator is constructed to obtain the sound field paramaters such as the magnitudes and directions of early reflections with moderate efforts. The proposed simulator is based on the hybrid ray tracing method that traces rays reached the listener position and convert them to image sound sources. By this approach, we can obtain the directional impulse response relatively easily with minimum casts. Simulation experiment results of several performace places are reported to how the versatility of the proposed simulator system.

최근 자동차용 청정 연료로서의 이용 가능성으로 주목받는 디메틸에테르를 액상 혼합 반응기에서 직접 합성 가스로부터 합성하였다. 메탄올 함성촉매와 감마알루미나의 혼성촉매를 사용한 결과, $H_2$/CO=1일 때, 메탄올 함성 촉매와 탈수촉매의 비가 8:2인 경우, 가장 높은 메탄옥 환산 생산량을 보였다. 또한 공간속도의 변화에 따른 디메틸에테르, 메탄올, 이산화탄소, 메탄 등 각 생성물에 대한 선택도의 변화는 거의 없이 일정하였다. 메탄옥 합성 반응 촉매만을 사용한 경우, 생성물 중 각 성분의 선택도는 반응가스의 공간속도에 따라 달라졌는데, 반응가스의 공간속도가 작아지면 생성물 중 디메틸에테르의 선택도는 변화가 없었으나, 이산화탄소의 발생량이 많고 메탄올의 생성이 적어졌다. 동일한 반응 조건에서 액상 반응과 시강 반응을 비교한 결과, DME 수율이 액상의 경우가 더 높았다.

In this study, we used the hybrid module that was composed of granular activated carbons (GAC) packing between module inside and outside of tubular ceramic microfiltration membrane for advanced drinking water treatment. Instead of natural organic matters (NOM) and fine inorganic particles in natural water source, modified solution was prepared with humic acid and kaolin. $N_2$-back-flushing of 10 sec was performed per every period of 10 min to minimize membrane fouling and to improve permeate flux (J). As a result, resistance of membrane fouling ($R_f$) decreased and J increased as concentration of humic acid changed from 10 mg/L to 2 mg/L step by step, and finally the highest total permeate volume ($V_T$) could be obtained at 2 mg/L. Then, treatment efficiencies of turbidity and $UV_{254}$ absorbance were excellent above 99.36% and 97.19%, respectively, but that of $UV_{254}$ absorbance for only microfiltration without GAC at 10 mg/L of humic acid was decreased a little as 90.84%.

Extracting students' own culture and resources as main sources in science class, we begin a research to explore teaching and learning settings that are more responsive to adolescents. This study has been designed to explore the funds of knowledge that students bring into middle school science class. It also focused on the features of teaching and learning settings that stimulated the autonomous inflow of students' funds of knowledge as resources of science learning. Data from participant observations and in-depth interviews with 7th grade students were qualitatively analyzed based on grounded theory. We found that students' funds of knowledge were formed from their family life, neighbor communities, peer group, and pop culture. The funds of knowledge based on peer culture emerged as the most salient factor of students' enhanced participation and utterance. Common features of classes that stimulated the inflow of funds of knowledge were analyzed to be: (1) hybrid spaces for learning designed in advance: (2) sharing and enlargement of the funds of knowledge that has been brought into the class: and (3) common orientation of the community of practice for knowledge co-construction and shared outcomes. From these findings, this paper discussed the educational implications for promoting students' potential resources to actual sources of science class. It also discussed students' development of participation specifically among the generally marginalized students. Science classes based on the funds of knowledge of students offer an increased possibility of knowledge co-construction through the hybridized interactions of student's everyday lives and science knowledge and lead to more meaningful learning experiences.

In multi-agent systems, How to coordinate the behaviors of the agents through learning is a very important problem. The most important problems in the multi-agent system are to accomplish a goal through the efficient coordination of several agents and to prevent collision with other agents. In this paper, we propose a novel approach by using hybrid learning strategy. It is used hybrid learning strategy to control the multi-agent system efficiently by using the spatial relationship among the agents. Through experiments, we can see approximate faster the goal then other strategies and avoids collision among the agents.

It has been widely known that the effect of diffracted waves at the tip of composite breakwater with finite length causes the change of standing wave height along the length of breakwater, the spatial change of wave pressure on caisson, and the occurrence of meandering damage on the different sliding distance in sequence. It is hard to deal with the spatial change of wave force on trunk of breakwater through the two-dimensional experiment and/or numerical analysis. In this study, two and three-dimensional numerical techniques with olaFlow model are used to approach the spatial change of wave force including the impulsive breaking wave pressure applied to trunk of breakwater, the effect of rear region, and the occurrence of diffracted waves at the tip of caisson located on the high crested rubble mound. In addition, it is thoroughly studied the mean wave height, mean horizontal velocity, and mean turbulent kinetic energy through the numerical analysis. In conclusion, it is confirmed that the larger wave pressure occurs at the front wall of caisson around the still water level than the original design conditions when it generates the shock-crushing wave pressure checked by not two-dimensional analysis, but three-dimensional analysis through the change of wave pressure applied to the caisson along the length of breakwater.
