This study examined changes in the energy landscape, focusing on the photovoltaic module carbon certification system. As the global photovoltaic market has been reorganized around Chinese companies, the South Korean government has pushed to strengthen the competitiveness of the nation's photovoltaic industry. However, a limitation remains in that the government-led effort was not sufficient to bring about dynamic changes in the energy landscape. Against this backdrop, this study explored the stages leading to the multi-level perspectives of "macro-environment, socio-technical regime, and niche" to track the process of the government and domestic photovoltaic companies as part of a socio-technical regime responding to global market changes. In particular, this study raised an issue with the conceptual discussion of multi-level perspective, which placed a particular emphasis on the rate of change at each level and the niche in which innovative experiments take place, and thus attempted to fill this gap by tracking the energy landscape that varies differently from space. These spatial discussions can track different carbon emissions coefficients and industrial characteristics for each country, and have a higher level of explanatory power for the system thus constructed. In addition, through discussions on the problems and implications of the government-led introduction of renewable energy policies, this study suggests the need to create and implement a field-oriented system.

Minor enterprises can successfully build up their market share plans in a relatively shorter time than compared with major enterprises, which require long time for design developments in their big organization. Therefore, there are some items that are more suitable to the minor enterprises. For example, computer desk may be the one. It must be one of the strategically suitable items of minor enterprises rather than of large enterprises because of their own easy production policies. This paper is based on a research report that I submitted to Gyongsan-Si, Gyongbuk-Do which supported a small company for a special purpose of its provincial economic policy. I took part in the research and suggested five types of characteristic concepts and the ideas. And as a result. the type war accepted as the most appropriate one of them to produce. And the acception was based on the following five factors; consumer's need, productivity, proper price, energy saving, and user' easiness.

This study interpreted a traditional garden of Korea through reception aesthetics. The 'gap' of acceptable aesthetics is found in the 'distance that occurs between writers and readers'. This study aims to interpret this gap between what the writer intends and what the reader expects. Boundaries do not limit traditional spaces in Korea and, therefore, are not limited by characteristics. These characteristics were studied from the perspectives of the author, the work, and the reader. The aspect first looked at the life and ideas of the gardener, the second analyzed the form and structure of the garden, and the last examined writings, from the past and present, of those who appreciated the garden. From the author's perspective, Sosoewon was understood as a garden that embodied the philosophy of Yang Sanbo. Second, the duality and indeterminateness were recognized as two characteristics of this work; artifacts in the garden were arranged in a natural form, and the gardens have indefinite boundaries, so they can be freely expanded and reduced. Finally, from the reader's perspective, it was noted that the beauty of this garden is enhanced through poetry, painting, and writing. Thus, historic gardens of Korea can be open spaces where the meaning of the garden is enriched through the free participation of viewers based on their own ideas.

흔히 사람이 살아가면서 없어선 안 될 요소로 의식주를 손꼽곤 한다. 그런데 이 3가지 요소 중에서 의류가 맨 앞에 포진함은 의미심장하다. 먹고 자는 행위보다 입는 행위가 더 중요해서 일까. 아마 잠시라도 사람의 곁을 떠나지 않으면 안 되는 필수적인 요소이기 때문에 의류를 제일 앞에 포진시킨 것이 아닐 까 한다. 사실 인간이 옷을 입지 않고 존재하는 시간은 얼마 되지 않는다. 은밀한 사적인 공간에서 아니면 인간은 입어야 하는 게 숙명이다. 반면 삶에 있어 반드시 필요한 입는 행위의 이면에는 빠는 행위, 즉 세탁의 행위가 숙명처럼 존재한다. 한번 입고 옷을 버리지 않은 이상 세탁은 삶에 있어 필수 불가결한 요소이다. 이러한 행위를 가장 편하게 만드는 이기가 세탁기이다. 세탁은 가정에서 하는 게 일반적이기만 상업용 세탁용 시장도 존재한다. 돈 주고 세탁을 맡기는 세탁소가 대표적인 업종이다. 그런데 최근 상업용 세탁 시장의 틈새시장으로 셀프 빨래방이 확대되고 있다. 셀프 빨래방은 말 그대도 소비자가 혼자 세탁기 및 건조기를 이용해 세탁을 하는 업태이다. 셀프세탁 문화의 확대가 전제되어야 하는 이 신업태가 과연 얼마만큼의 시장 파급력을 형성할 수 있을 까. 이 신업태의 중심에 있는 코인업사는 셀프 빨래방의 급속 확산과 성공을 자신하고 있다. 무인매장으로 24시간, 365일 운영을 할 수 있다는 사업 본연의 장점에다 최근 매장 경쟁력을 강화할 야심에 찬 제품군까지 준비했다. 바야흐로 셀프 빨래방의 전성시대를 열어가려하는 코인업의 신사업 추진 현황을 따라가 봤다.

Power-related issues have become important considerations in current generation microprocessor design. One of these issues is that of elevated on-chip temperatures. This has an adverse effect on cooling cost and, if not addressed suitably, on chip reliability. In this paper we investigate the general trade-offs between temporal and spatial hot spot mitigation schemes and thermal time constants, workload variations and microprocessor power distributions. By leveraging spatial and temporal heat slacks, our schemes enable lowering of on-chip unit temperatures by changing the workload in a timely manner with Operating System (OS) and existing hardware support.

The purpose of this study is to explain the growth of the business area for migrant workers and the spatial characteristics of the start-up of business, location selection and market area of the employers from foreign countries by focusing on the ethnic networks in Wongok-Dong, Ansan. The results of this study are summarized as follows. The businesses for Chinese workers among migrant workers are located densely and have many kinds of businesses relative to the businesses for migrants from other countries having small number of migrant workers in this area. Moreover, The employers from foreign countries come to Korea through the migrant networks. And they are located in Wongok-Dong, Ansan in which the migrants community is developed. These things made it clear that they regard ethnic networks as important factor for migrant businesses. While the market area of businesses for Chinese workers is restricted to Wongok-Dong or Ansan city, the market areas of businesses for migrant workers from other countries are expanded nationwide through ethnic networks.

The interest in the use of shield TBM (Tunnel Boring Machine) on the tunnel excavation has been increased rapidly in Korea. The shield TBM tunnel is generally designed as non-drainage tunnel. Consequently, if water leakage through the segment joints happens, big problems on the usage and stability of tunnel can be occurred. In this study, the variation of waterproof capacity of hydrophilic rubber waterstop by the construction error and excessive displacement of segment was studied. In particular, the waterproof capacity of each of single and double layer arrangements of hydrophilic rubber waterstop was examined to verify the efficiency of the double layer arrangement. The test results show that the single layer and double layer hydrophilic rubber waterstop showed the same waterproof performance. hydrophilic rubber waterstop has favorable on the offset, however unfavorable on the gap.

This study is intended to derive the adaptive reuse techniques through the history and aspects of new construction, extension, repair, and other works, limited to the deep and narrow lots facing Seongan-gil and Nammun-gil in Nammun-ro 2 ga of Cheongju, the historic urban area. The results are as follows. 1) In the case of newly built reinforced concrete buildings, the central part of the top floor of the residence or all floors are opened to the open space(void) to facilitate lighting and ventilation. This is developed as a convection phenomenon due to the temperature difference from the slits between buildings, which affects the entire air flow of the block. 2) The buildings of extension and repair are composed of two-story masonry or steel frame, both the front store facing the road and the house on the back, but it looks like one because it is in contact with each other. If only a small gap between the front and rear buildings is restored to an external space or a space equipped with sun light, a small breath can be provided in lighting and ventilation. 3) The existing two-story wooden stores and houses have lost their external space due to repairs. With minimal intervention to restore the small courtyard, slits, and space under the eaves, it will not only improve lighting and ventilation, but also create a unique appearance as a segment of the elongated store.

In a typical living space, windows are directly exposed to the external noise environment. The best way to reduce outside noise is to block it from the outside, not the inside. Exterior blinds for blocking sunlight are commercialized in various ways. However, it has not yet been actively utilized in Korea. In the previous study, an experiment was conducted in an accredited laboratory to verify the sound insulation performance of an external motorized blind manufactured for shading. And it was verified that there is a sound insulation performance of 6 dBA compared to the reduction performance of a general window. In this study, we tried to confirm the reduction performance by applying the sound insulation performance of external electric blinds to windows in actual living spaces. In addition, an improvement plan was sought to increase the effective noise reduction performance. As a result of the measurement, the reduction performance of the external motorized blind itself was insufficient at the level of 1 dBA to 3 dBA. However, additional reduction performance of the 2 dBA level was confirmed by filling the gap between the blind slits.
