미디어파사드의 개념 및 속성에 대한 사회적 공감대가 형성되어 있지 않은 상태에서 적용 사례가 빠르게 증가함에 따라 서울시는 관리의 필요성을 느끼고 관리체계를 마련하였으나 그 미흡함으로 인하여 혼란이 야기되고 있는 실정이다. 본 논문은 현 서울시 미디어파사드 관리체계의 분석을 통한 문제점을 도출하고 해외사례 조사로부터의 시사점을 바탕으로 서울시 미디어파사드 관리방안의 실효성을 제고하기 위한 개선방안을 제시한다. 첫째, 미디어파사드 관련제도의 강화가 필요하다. 세부적인 사항으로 빛공해조례에 관리 및 심의대상을 명확히 명시하고, 건축물 허가 제도와 연계하여 심의절차를 개선하며, 빛공해방지법에 근거하여 빛공해조례의 개선명령 및 벌칙기준을 보완한다. 둘째, 허용구역을 통하여 미디어파사드의 입지를 관리한다. 세부적인 사항으로 금지구역이 아닌 허용구역을 지정하는 포지티브 방식을 취함으로써 효율성을 높이고, 허용여부를 위하여 지역별 접근을 도모한다. 셋째, 미디어파사드에 대한 통합적 관리기준을 마련한다. 세부적인 사항으로 미디어파사드 기본계획을 수립하여 허용구역 및 기본원칙을 제시하고, 허용구역별 경관계획을 수립하여 각 구역별 장소성 및 특성을 강화한다. As the installation of media facades has increased rapidly in Seoul, the city government has established a management system that nonetheless has been insufficient and failed to provide clarity. This study therefore suggests ways to improve the efficiency of media facade management system based on an analysis of the systems in Seoul and implications from cities overseas. First, the regulation of media facades needs to be strengthened. For this, the subject of management and review system in the city?s ‘light pollution ordinance’ should be clarified; the review process connected to building permits should be improved; and the order and penalty standards of the ordinance should be strengthened. Second, media facades should be installed only in designated areas. For this, the applicable areas should be designated, and locally-based standards should be established for the permitting of media facades in each area. Third, an integrated management standard for media facades should be prepared. For this, a media facade master plan should be prepared, and the urban landscape plan for each applicable area should be prepared to intensify the placeness and the special quality of each area.

The study analyzed Urban Landscape Plans of Seoul based on the Landscape Law, as well as management and implementation system based on the Plan. Furthermore, it compared to those of the major Japanese cities, Tokyo, Osaka, and Kyoto, which have varied experiences in the system and operation regarding the urban landscape. Finally, it deduced suggestions to increase the efficiency of urban landscape management through the urban landscape plan in Seoul and other cities of Korea. The suggestions are as follows. First, in the aspect of system and contents of the urban landscape plan, association with other laws and systems should be pursued to solve the conflicts and as well enhance the efficiency. Moreover, it should choose prior strategy for the approach in stages and designate concrete landscape elements with management system. Second, in the aspect of urban landscape management scheme, it should prepare local guidelines and initiate regulation with concrete and quantitative standard. Third, in the implementation aspect, it needs to establish deliberation system to confirm the conformity with the guidelines and standards.

Seoul city planned both Seoul Landscape Master Plan and Seoul Urban District Landscape Plan in 2009 based on the Landscape Law enacted in 2007. Both plans designated ``Landscape Management Zones`` according to the vision and basic concepts for each landscape type such as urban district, natural green, waterfront, and historic cultural landscape. For each zone, the plans provided ``Landscape Design Guideline and Checklist`` suggesting basic principles and directions to incite to conserve and cultivate the valuable landscape in the zones. As a tool to apply the guideline, Seoul adopted ``Landscape Self Check System``. The System requires architect himself/herself to check the Landscape Design Guideline and Checklist and to submit it along with the building permit documents. The system is about to be operated compulsorily after the trial application period (01 April 2009~ 31 March 2011). The study aims to monitor the actual condition and problems and to draw improvement schemes for the effective landscape management before the obligatory operation of the ``Landscape Self Check System``. The study seeks the supplementation and improvement schemes for the landscape management system for the stabilized operation. The main contents of the study are assessment of trial application, survey of officials and architects, analysis on applied cases, and case studies of Japanese cities. The assessment of trial application shows that the submission rate of the ``Landscape Design Guideline and Checklist`` is around 20% which is quite low. The rate of correct recognition of the officials who collect the checklists reaches about the half (about 52%), and the rate of wrong submission reaches up to 34% which is not improving. Analyzing the rates by each Gu-district shows that the variation of the rates between the Gu-districts are relatively high and that the officials are important not only in collecting the checklists correctly but also in encouraging and guiding the architects. The study conducted a survey to investigate the perception of interested parties. It shows that Landscape Self Check System actually changed the perception of the architects about landscape. About 50% of the architects responded that the system contributed to improve the recognition and consideration for landscape, and about 40% of the architects who think the guideline was helpful also answered that the guideline provided the effective information about the landscape resources and the direction for consideration. The survey illustrates the necessity of search system of the landscape management zones and the necessity to complement the design guidelines. The analysis of applied cases of the design guidelines shows that the architects checked the checklist routinely and repeatedly, and they confused the marks between ``not considered`` and ``not relevant.`` In addition, it is ambiguous to assess whether the guideline is reflected on buildings or not. This ambiguity might cause problems when ``pre-conference`` system is adopted, and therefore it is necessary to prepare operation manual. The study drew improvement schemes as a result; establishment of landscape management system, improvement of manpower and organization, and supplementation of Landscape Design Guideline and Checklist. First is the establishment of landscape management system to secure the power of execution. It is necessary to grade the management system into ``pre-conference`` and ``pre-consultation`` based on the influence of a building to the surrounding landscape and importance of the location, make the submission compulsory through supplementing the building permit process, and finally establish the online system to search the zones and guidelines linked to Seoul GIS portal system(http://gis.seoul.go.kr). Second is the improvement of manpower and organization for landscape management. It is necessary to increase the conference ability of the officials through preparing an operation manual for landscape management system, educate and cultivate the people including the officials and architects for the effective operation, and to secure the labor pool for the landscape adviser. Third is the supplementation of Landscape Design Guideline and Checklist. It is necessary to clarify the object of the landscape management for each zone and direction of each element, refine the design guidelines, and make to submit the supplementary explanations to check whether the landscape is considered or not. As the specific action plan to operate the above improvement schemes, the study suggested to include the articles for the ``pre-conference`` and ``pre- consultation`` system in the Seoul Landscape Ordinance when it is amended according to the amendment of the Landscape Law (legislation notice). It should include the ground to refuse a building permit application which lacks confirmation document of pre-consultation or pre-consultation and include an operation policy for landscape review. In addition, to increase the executive ability of the landscape plans, it should prepare the details to relieve the architectural standard for the buildings with excellent landscape, the support system for the Gu-district with excellent landscape management system, and the online search system.

Seoul has the indigenous urban structure which is composed of mountains and rivers. Especially hillside residential areas are mixed with formed spontaneously and formed with plan, so these areas show the most inherent feature in urban form and landscape of Seoul. Generally building height of hillside areas has been managed by zoning system, hence buildings are harmonious with its background. Architectural form, exterior of buildings in hillside areas are much more important than buildings on level ground. Despite that, since appropriate manner to control and formulate urban landscape does not exist, there is a limit to manage landscape of close and middle view. Since hillside residential areas are excluded from the site designated for the housing redevelopment district, houses are old and blighted in these areas. therefore it is urgent to come up with methods of improving the residential environment and houses in hillside areas. According to the American and Japanese experiences, Seoul Metropolitan Government ought to set up goals of management clearly, legislate strict regulations such as law and institution, and draw up a guideline of improving activities in hillside residential areas, so to speak, it is time to start to manage the landscape not by zoning system but by the planning guideline. Guideline indicates guiding principles of landscape, residential environment and building. The landscape section was set up by adapting Seoul landscape masterplan. The residential environment section composed of constructing parking lot and creating pedestrian-friendly environment. Third section suggests ground rules of architectural form and design considering landscape for building a new house and remodeling in hillside areas. Detailed rules of architectural design are laid down by resident’s agreement, whereas remodeling is depended on how much financial aid SMG can provide. Remodeling is classified into two types:primary type is the exterior remodeling as public goods, and secondary remodeling is structural strengthening in preparation for fires and landslides. The conclusion of study suggests that government-led management by powerful regulation shift to resident-led management of hilly area according to the characteristics of residents and landscape. Management tool of building in hillside residential area should be developed focusing on three principles:management of both building height and architectural form, reviewing building based on design guideline, framing management system of hillside residential area through Residential Environment Management Project. Furthermore management system which is having residents form appropriate landscape with their own efforts should be built in the end.

This paper proposes the configuration of parallel hybrid wheel loader and power control algorithm. The target vehicle is composed of engine, battery, motor, torque converter, transmission, vhehicle, and wheel. The main control strategy of the target vehicle is to optimally distribute demanded power from the power sources by considering highest efficiency point of the engine and motor. Furthermore, when there is no engine load, the idle stop technology is applied. A hybrid wheel loader model and the proposed algorithm are developed by unsin AMEsim, verified through the simulation, and compared with the results of conventional wheel loader. Simulation results show fuel reduction and narrow swing of SOC, and thus demonstrate the feasibility and effectiveness of the proposed algorithm.
