  • The Manual on Uniform Traffic Control Devices advises that, "Signs should be placed on the right side of the roadway where they are easily recognized and understood by road users." Guidance is provided on the spacing and prioritization of signs, and in some conditions, additional steps may be needed to ensure that signs are conspicuous. This study proposes a design methodology using ergonomics concepts applied to traffic sign and street name signs. Initially, a literature revision on cognitive ergonomics is performed. Several design methodologies are analyzed and the aspects to be considered in traffic signs are selected.. In this study, problems of traffic signs in Korea were identified through the comparative analysis of domestic and foreign traffic signs and a prototype of ergonomic traffic sign was developed based on the analysis results. And the driver's views on the developed traffic sign were investigated. In addition, based on the results of this study, this study is to provide the necessary foundation for improving traffic signs in order to help the various age groups of drivers to reach their destinations without difficulties when they drive.

  • 3GPP long-term evolution(LTE) band 2.3~2.4 GHz is adjacent to 2.4~2.5 GHz band for WLAN, and therefore compatibility study of the two systems is desirable. We propose a dynamic system simulation methodology to investigate the effect of WLAN interference on LTE systems. As capturing space/time/frequency changes in system parameters, the dynamic system simulation can exactly predict real system performance. Using the proposed methodology, we obtain LTE downlink throughput loss for the frequency separation between the two systems. Throughput loss under 1 % is obtained from guard band over 11 MHz(single channel allocation) or 10 MHz(three channel allocation).

  • 종래의 개발은 양면성을 가지고 있다. 하나는 개발로 인한 경제적 효율성과 편리성 부분이고, 다른 하나는 그러한 개발로 인한 자연훼손 및 생태계 파괴이다. 이로 인해 개발과 보전은 양립할 수 없는 상반적인 개념으로 받아들여져 왔고, 개발론과 보전론의 대립적 구도가 지속되어 왔다. 우리나라는 국토의 65% 이상이 산지이기 때문에 산지의 부분적 개발은 피할 수 없는 사회적 요구인 동시에, 산지는 자연생태계의 보고로서 생태계 보전이 필수적인 지역이다. 이러한 산지 개발과 보전에 대한 상반적 이해를 통합하여 자연과 인간의 공생체계를 갖추기 위해서는 인간중심의 사고에서 탈피하여 사람과 생태계 그리고 자연을 하나로 보는 총체적인 측면에서 접근하는 새로운 패러다임이 설정되어야 한다. 본 연구에서는 산지의 정량적인 가치를 평가하기 위해 시 공간적으로 다양한 인자들에 대해 시스템적인 관점에서 그 중요성을 고려하고자 하는 에머지 개념을 통해 산지 본래의 가치를 평가하였다. 에머지 개념은 그 동안 생태계가치평가, 개발사업의 편익-비용평가, 환경수용력 평가, 개발대안 평가, 환경계정, 환경훼손 소송관련 비용 평가 등에 적용되었다. 이러한 에머지 개념을 이용한 평가 방법을 통한 의사결정이 이루어지면 산지뿐만이 아닌 생태계의 지속가능한 이용을 실현하기 위한 적절한 정책의 선택과 이의 이행 실효성을 높일 수 있을 것으로 기대되며, 자연환경 가치의 정량적 평가를 통해서 우리는 한층 더 자연환경 및 자원의 다원적 기능에 대한 자각을 할 수 있을 것으로 판단된다.

  • Hwaseong serial murders are not now having any significant concern either with Hwaseong City or Dongtan New Town, a region in Hwaseong City, both spatial and temporal manners. However, despite that, people have come to see Hwaseong City with negative ideas as the mass media drove the people to do so. In this study, how films and newspaper articles have created those negative images of Hwaseong City was investigated and afterwards, residents and students living in Dongtan New Town had interviews on what they think about the negative regional images. The study, then, worked on a mental map and others based on what it learned from the interviews. Regional identity confusion is now being discovered out of the people's resistance against the negative images of the city and through such research process described before, the study discussed this regional identity confusion caused by living as residents in Hwaseong and living as residents in Dongtan New Town. In addition, the study revealed sense of place of Dongtan New Town and aspects of the regional identity confusion with this Dongtan New Town growing both with symbolic meanings as a place of murders, an awful crime, and spatial meanings as another place of dynamic developments and improvements.

  • The objective of this study is to propose the principle and method of the spatial system modification for the compatibility of habitability and tourism convenience in cultural property villages. Based on the field survey on tourists' routes, activities and their durations in Oeam-maeul, the problems of conflict, between habitability/residents and tourism/tourists, and their causes are analyzed. And the modification principle and method of spatial system is proposed as follows; The basic principle of the spatial system modification is to respect the traditional hierarchy in village roads, between the main road and sub-roads, and the territoriality of settlement space that is typically differentiated as the social, individual, and ceremonial domains, from the front to rear part of settlement. With this principle, it is recommended to restrict the tour route to one that is composed of the main road and the periphery road of housing area, and some connecting sub-roads. based on the surveyed tourists's routes. And it is suggested that the tourist facilities, whether they are existing houses or newly built buildings, and the tourist programs are necessary for experience tourism to cultural property villages, and they are proposed to be placed along the restricted tour route.

  • This paper analyzes the interference effect of ISM(Industrial Scientific Medical) equipment on WLAN in order to protect WLAN in interference environment which WLAN Station is close to ISM equipment. CISPR(International Special Committee on Radio Interference) radiation limit standard was used for interfering power of ISM equipment. Then, MCL(Minimum Coupling Loss) which is for the worst case and MC(Monte Carlo) which is based on statistic interference probability are used to get protection distance. As a result, the protection distance of 105 m was calculated by using MCL for the worst case. And, the protection distance of 17 m was calculated by using MC for statistic analysis.

  • LED-based lighting motivated by significant energy savings provides an opportunistic development of widespread free-space optical communications. Their transceivers have a variety of competitive advantages over RF including high bandwidth density, reliability, lower energy consumption, and long lifetime. But, it is difficult for existing buildings and structures such as ships and vehicles to install the communication cable to the ceiling. In this paper, controller area network (CAN)-based LED lighting communication systems were proposed. Results indicate the viability of developing inexpensive CAN interface modules and transceivers might be embedded in lighting products to support the indoor wireless networking.

A Study on the Coexistance of Ganghak(講學) and Yusik(遊息) space of Oksan Confucian Academy, Gyeongju: Directed Attention Restoration Theory Perspectives (주의집중 피로회복이론의 장으로 본 경주 옥산서원 강학 및 유식공간의 일원적 공간성)

  • This study attempts to understand and explain how "Directed Attention Restorative Environment (DARE)" is managed and fostered in "Gang-Hak (講學)" and "Yu-Sik (遊息)" spaces both inside and outside of Oksan Seowon Confucian Academy, Gyeongju. Directed Attention is a pivotal element in human information processing so that its restoration is crucial for effective thinking and learning. According to Kaplan & Kaplan's Attention Restoration Theory, an environment, in order to be restorative, should have four elements: 'Being Away,' 'Extent,' 'Fascination,' and 'Compatibility.' We could confirm OkSan Seowon Confucian Academy has an inner logic that integrates two basically different spacial concepts of "Jangsu" and "Yusik" and thus fosters the Attention Restorative Environment. Particularly, the Four Mountains and Five Platforms (四山五臺) surrounding the premises provides an excellent learning environment, and is in itself educational in terms of the Neo-Confucian epistemology with "Attaining Knowledge by way of Positioning Things (格物致知)" as its principle precept, and of its aesthetics with "Connectedness with Nature" as its central tenet. This study attempts to recapture the value of Korea's cultural heritage concerning the Human/Nature relationship; and it may provide useful insights and practical guidelines/grounds in designing today's schools and campuses, where the young people's needs for the Directed Attention- and Attention Restorative- Servicescapes seem to be greater than ever.

  • One of the oldest chestnuts in economic geography is this: Cultural and creative industries strongly gather in large cities and this geographic concentration of economic activities leads to regional development. Of course, depending on the circumstances, such a proposition still holds good. But, under the current paradigm shift to knowledge-based economy, it may be open to question. This study aims to investigate financing and knowledge accumulation in the film industry through an alternative framework for explaining their spatial distributions, "formation mechanism of economic space." From the fact that their production organizations are formed on a project basis, project-based financing structure in the investment stage and knowledge accumulation process in the production stage form both axes of it. Film industry as the most mature industry among the cultural and creative industries does not always concentrate in a certain place (industrial agglomeration) or show metropolis-oriented preference. This allows us to reconsider our long brooding theory.

  • Going beyond the previous formulations of development theories, the present paper explores the effects other than political economy on quality of life in a rapidly developing country. The major analysis takes up the historical trend and nature of the developmental transformation that is partially a consequences of state structures and partially autonomous form it in South Korea. Also, it diagnoses developmental pathways for the future track by constructing a baseline model for state transition on the basis of power game between the state and civil society in the country. The results of the historical analysis show that civil society has been transformed in the course of confrontations and interactions between the state and nationalist social movement. The distinction between developmental(or bureaucratic authoritarian) and democratic state is presented to show that these are two qualitatively different aspects of state of state power, requiring separate analytical treatment. Furthermore, the state-centric approach which emphasizes the active role of the state at the sacrifice of societal fabric-constraining social conditions for quality of life - appears to be modified. On the contrary, the impact of civil society is transmitted both directly and indirectly via labor and ecological movement for quality of life, which is critical to the formation of the welfare state in the country. The prospect for sustainable development in Korea lies in providng and expanding quality of life in terms of the financial feasibility of the state through the public-private cooperation, and abstaining from drastic and radical commitment to welfare services as is the case with the European declines in welfare state, Further studies are needed to examine the interrelationships in different historical and cultural settings of developing counties to estimate a theory of quality of life and social justice.
