  • 도심과 사회기반시설의 확장에 대한 수요로 인해 군사시설의 이전이나 시설의 지하화가 지속적으로 요구되고 있다. 그러나 탄약시설과 같은 시설을 횡단할 때에는 탄약이 우발적으로 폭발하지 않도록 고도의 안전성 평가가 선행되어야 한다. 이에 지중 구조물의 건설을 위한 발파작업이 지상의 탄약시설에 미치는 영향을 분석하기 위해 국방부와 한국철도시설공단간 협의에 의해 진행되는 신안선 복선 전철 설계구간 중 군사 보안구역을 통과하여 건설되는 터널구간에 대해 사례연구를 실시하였다. 폭발현상에 의한 진동의 속도를 수치해석 프로그램인 GTS-NX를 활용하여 예측하였고 문헌조사를 통해 모든 형태의 구조물에 대해서도 안전에 영향을 미치지 않는 0.2cm/sec의 지반진동속도를 안전성 평가기준으로 제시하였다. 본 연구에서 활용된 안전성 평가지표와 절차는 향후 탄약시설을 횡단하는 사회기반시설 계획 시 안전성 평가의 지표로 활용될 수 있을 것이다.

  • A city evolves over time. It grows, transforms, and sometimes degrades. Chuncheon is at a turning point from a city souggling with regulations regarding clean water supply and a military encampment to a masterpiece city with a sustainable vision. The city is getting ready to restructure itself to become a world-famous culture and tourism complex expanding its physical boundary across the Camp Page site and absorbing Jungdo as a major tourist attraction. The landscape in the future blueprint of Chuncheon will play a great role in restructuring urban form. The regenerated in will have a new networked open space system as well as re-evaluated landscape resources. The hybrid theoretical practice called 'landscape urbanism' burgeoning in the fields between 'landscape architecture' and 'urbanism' can guide us in considering the terms of the relationship between a city and landscape when we design a future city Landscape urbanism is considered to be an effective framework by which we can diagnose the current status of a landscape in our contemporary urban design practice in Korea. This paper tries to provide a different perspective from the viewpoint of landscape urbanism to decipher the hidden implications of the social agreement on the role of landscape in urban structure by re-reading eight design proposals presented for the ChunCheon G5 international design competition based on the main principles of landscape urbanism. The G5 design competition is a great opportunity to test out new ideas on a city, demonstrating the relative values among various urban-design professional realms. First, this paper provides an overview of the main ideas of landscape urbanism based on the literature review and case studies. Second, framework categories are suggested in order to extract the explicit and implicit ideas on the landscape. Third, eight proposals are reviewed according to the suggested categories to situate the current landscape design of Korea within the mainstream of contemporary practice of landscape urbanism. Based on the review of eight proposals, the following diagnostic conclusions are made; first, the ideas of landscape urbanism have not been actively introduced in large-scaled urban landscape projects in Korea like Chuncheon G5. Second, it remains to be a big task for landscape professions to be able to participate in design consortiums on an equal footing. Third, In order to introduce and reify the ideas of landscape urbanism in Korea, it is inevitable and critical to test the ideas in both academic fields and professional practices to find the appropriately adjusted model of landscape urbanism.

  • Traffic and emergency monitoring systems are essential constituents of Intelligent Transportation System (ITS) technologies, but the lack of traffic monitoring has become a primary weakness in providing prompt emergency services. Demonstrated in numerous military applications, unmanned aerial vehicles (UAVs) have great potentials as a part of ITS infrastructure for providing quick and real-time aerial video images of large surface area to the ground. Despite of obvious advantages of UAVs for traffic monitoring and many other civil applications, it is rare to encounter success stories of UAVs in civil application including transportation. The objective of this paper is to report the outcomes of research supported by the state agency in US to investigate the feasibility of integrating UAVs into urban highway traffic monitoring as a part of ITS infrastructure. These include current technical and regulatory issues, and possible suggestions for a future UAV system in civil applications.

  • In Korea, the modular construction method was applied to the construction of facilities such as military barracks and school dormitories, beginning with the pilot project of Seoul New Elementary School in 2003. In 2017, public modular houses were supplied to Busan(Yongho-dong) and Seoul(Gayang-dong), and modular housing is expected to continue to be supplied in the future. However, there is no clear construction standard for the modular housing construction yet, and there are few cases where the infill modular system is applied. Therefore, this study established the work breakdown structure and proposed a standard process focusing on the infill modular system applied to the construction of Dujeong-dong modular house in Cheonan. Level 1 of the work breakdown structure by construction stage of Infill modular was defined as modular manufacturing, assembly, and finishing process. Level 2 was defined as preparation, modular production, modular infill, modular fixing, floor plastering, building finishing, and other site finishing. Level 3 is defined as 57 detailed unit work of infill modular construction. The standard process of infill modular is proposed for the assembly stage that is commonly applicable to infill modular housing construction. The results of this study can be used for the process plan, transportation plan, lifting plan of modular housing construction.

  • The categories of national health problems may be mainly divided into health promotion, problems of diseases, and population-economic problems which are indirectly related to health. Of them, the problems of diseases will be exclusively dealt with this speech. Rurality and Disease Problems There are many differences between rural and urban areas. In general, indicators of rurality are small size of towns, dispersion of the population, remoteness from urban centers, inadequacy of public transportation, poor communication, inadequate sanitation, poor housing, poverty, little education lack of health personnels and facilities, and in-accessibility to health services. The influence of such conditions creates, directly or indirectly, many problems of diseases in the rural areas. Those art the occurrence of preventable diseases, deterioration and prolongation of illness due to loss of chance to get early treatment, decreased or prolonged labour force loss, unnecessary death, doubling of medical cost, and economic loss. Some Considerations of Innovative Approach The followings art some considerations of innovative approaches to the problems of diseases in the rural Korea. 1. It would be essential goal of the innovative approaches that the damage and economic loss due to diseases will be maintained to minimum level by minimizing the absolute amount of the diseases, and by moderating the fee for medical cares. The goal of the minimization of the disease amount may be achieved by preventive services and early treatment, and the goal of moderating the medical fee may be achieved by lowering the prime cost and by adjusting the medical fees to reasonable level. 2. Community health service or community medicine will be adopted as a innovative means to disease problems. In this case, a community is defined as an unit area where supply and utilization of primary service activities can be accomplished within a day. The essential nature o the community health service should be such activities as health promotion, preventive measures, medical care, and rehabilitation performing efficiently through the organized efforts of the residents in a community. Each service activity should cover all members of the residents in a community in its plan and performance. The cooperation of the community peoples in one of the essential elements for success of the service program, The motivations of their cooperative mood may be activated through several ways: when the participation of the residents in service program of especially the direct participation of organized cooperation of the area leaders art achieved through a means of health education: when the residents get actual experience of having received the benefit of good quality services; and when the health personnels being armed with an idealism that they art working in the areas to help health problems of the residents, maintain good human relationships with them. For the success of a community health service program, a personnel who is in charge of leadership and has an able, a sincere and a steady characters seems to be required in a community. The government should lead and support the community health service programs of the nation under the basis of results appeared in the demonstrative programs so as to be carried out the programs efficiently. Moss of the health problems may be treated properly in the community levels through suitable community health service programs but there might be some problems which art beyond their abilities to be dealt with. To solve such problems each community health service program should be under the referral systems which are connected with health centers, hospitals, and so forth. 3. An approach should be intensively groped to have a physician in each community. The shortage of physicians in rural areas is world-wide problem and so is the Korean situation. In the past the government has initiated a system of area-limited physician, coercion, and a small scale of scholarship program with unsatisfactory results. But there might be ways of achieving the goal by intervice, broadened, and continuous approaches. There will be several ways of approach to motivate the physicians to be settled in a rural community. They are, for examples, to expos the students to the community health service programs during training, to be run community health service programs by every health or medical schools and other main medical facilities, communication activities and advertisement, desire of community peoples to invite a physician, scholarship program, payment of satisfactory level, fulfilment of military obligation in case of a future draft, economic growth and development of rural communities, sufficiency of health and medical facilities, provision of proper medical care system, coercion, and so forth. And, hopefully, more useful reference data on the motivations may be available when a survey be conducted to the physicians who are presently engaging in the rural community levels. 4. In communities where the availability of a physician is difficult, a trial to use physician extenders, under certain conditions, may be considered. The reason is that it would be beneficial for the health of the residents to give them the remedies of primary medical care through the extenders rather than to leave their medical problems out of management. The followings are the conditions to be considered when the physician extenders are used: their positions will be prescribed as a temporary one instead of permanent one so as to allow easy replacement of the position with a physician applicant; the extender will be under periodic direction and supervision of a physician, and also referral channel will be provided: legal constraints will be placed upon the extenders primary care practice, and the physician extenders will used only under the public medical care system. 5. For the balanced health care delivery, a greater investment to the rural areas is needed to compensate weak points of a rurality. The characteristics of a rurality has been already mentioned. The objective of balanced service for rural communities to level up that of urban areas will be hard to achieve without greater efforts and supports. For example, rural communities need mobile powers more than urban areas, communication network is extremely necessary at health delivery facilities in rural areas as well as the need of urban areas, health and medical facilities in rural areas should be provided more substantially than those of urban areas to minimize, in a sense, the amount of patient consultation and request of laboratory specimens through referral system of which procedures are more troublesome in rural areas, and more intensive control measures against communicable diseases are needed in rural areas where greater numbers of cases are occurred under the poor sanitary conditions.

  • UAV(Unmanned Aerial Vehicle)는 일반 유인 항공기나 위성에 비해 경제성이 크고, 대상물에 접근이 용이하여 군사적인 목적으로 많이 이용되어 왔다. 최근에는 IT 기술의 발전으로 다양한 센서를 탑재한 UAV가 출시되고 있으며 측량, 농업, 기상관측, 통신, 방송, 스포츠 등 광범위한 분야에서 이용이 증가하고 있으며, 공간정보를 제작하고 활용하는 분야에서 UAV를 활용하기 위한 다양한 연구와 시도가 증가하고 있다. 하지만 기존의 연구는 사진측량과 관련된 연구가 대부분이며, LiDAR(Light Detection And Ranging)에 대한 분석적 연구는 부족한 실정이다. 이에 본 연구에서는 공간정보 분야 활용을 위한 UAV LiDAR 센서의 특징을 분석하고자 하였다. LiDAR 센서의 취득속도, 반사횟수 등 상용화된 LiDAR 센서의 성능을 조사하고, 비슷한 정확도와 데이터 취득 가능 거리를 가지는 Surveyor Ultra와 VX15 모델을 선정하여 데이터 취득 및 분석을 수행하였다. 연구를 통해 각 센서별로 연구대상지의 DSM(Digital Surface Model)을 생성하고, 비교를 통해 데이터의 밀도, 정밀도, 식생지역에서 지면 데이터의 취득 등 특징을 제시하였다. UAV LiDAR 센서는 0.03m~0.05m의 정확도를 나타내었으며, 효과적인 활용을 위해서는 데이터의 특징들을 고려한 장비의 선정이 필요할 것으로 판단된다. 향후, 추가적인 연구를 통해 도심지역, 산림지역 등 다양한 지역에 대한 데이터 취득 및 분석이 이루어 진다면 UAV LiDAR의 활용성을 제시할 수 있을 것이다.
