TFT LCD 생산 공정에 사용되는 정밀측정/검사/생산장비가 위치하는 바닥의 진동문제는 크게 장비자체의 가동에 의한 것과 장비외부의 가진원에 의해서 정밀장비의 바닥에 진동이 발생하게 된다. 이러한 진동문제는 건물을 설계 시공하는 건축자의 입장에서는 장비 가동전 건물 인수시 진동문제에 관심이 있으나 장비를 운영하는 사용자의 입장에서는 장비 가동전의 진동문제와 더불어 장비 가동시 장비내부의 진동원에 대해서도 진동대책을 요구하게 된다. 따라서 양자의 진동문제 해결을 위해서는 정밀장비 주변의 진동원에 대한 동하중 설계자료와 함께 장비 가동시 바닥에 진동을 발생시키는 진동원인 장비에 대해서 동하중을 파악하여야 한다. 장비기초의 단위하중에 대한 진동응답을 표현하는 주파수 전달함수는 이러한 동하중과 바닥의 진동허용규제치를 동시에 표현하는 요소로 기존의 정밀장비가 요구하는 장비바닥의 진동허용규제치와 함께 동하중을 유발하는 장비기초에서는 반드시 구조물의 동강성 허용규제치를 이용한 구조물의 동적설계가 요구된다.

전자제품의 고기능화에 따라 Controller의 중요성은 점점 증대되고 있다. 따라서 Controller(이하 PCB라 칭함)의 제조 공정에서 납땜 관련 Board 재료, Flux, Flux 탄화 연기 등은 식물의 고사 현상등 지구환경을 위협하고 있다. 특히, 자동차 매연이나 도장 또는 PCB 납땜시 SOX, NOX, 탄화수소계등이 휘발하게 되며 아황산 가스 나 질소 산화물이 대기중에서 물과 반응하여 황산 또는 질산으로 변하여 PH 5.6이하 의 산성비를 내리게 한다. 이 산성비는 삼림피해 어류감소 등 생태계를 파괴하고 콘 크리트 철재등 건축 자재물을 부사시킨다. 또한 바람에 의해 인접국가에도 막대한 피해를 주고 있다. 특히 폐가전제품의 PCB 접합부에 산성비가 접촉되면 Pb 이온이 용출되어 토양 및 수질오염, 인체피해 등 심각한 영향을 미치게 된다. 최근 이와관련 세계 각국의 규제 움직임이 활발해지고 있어, 본 논문은 전자기기 제품의 심장인 PCB 와 관계된 환경오염 대상물질의 규제동향과 심각성 및 이에 대한 환경피해 Mechanism 을 분석하여 실장기술에 있어서 총체적인 환경대응 방안을 모색하고자 한다.

It should be noted that current rules and provisions of the law, such as the act of military air base and the act of the construction, do not provide a fairly good solution regarding the conflict between the company and the air force. The act of military air base does not have the jurisdiction on the matters occurring outside the edge of the flight safety zone. Freezing measure about the construction permit is not suitable for this case. A sort of policy or revision of the law will be needed to foster the transaction between parties in question which may be useful for enhancing overall efficiency.

In drafting the standards on changes in current conditions, the height or the number of stories is applied in a restrictive manner by limiting to securing the distance to vertical surface for cultural properties within the influence investigation area, but this is expected to have a negative impact on the surrounding sceneries as well as results in the dwarfing phenomenon for precious cultural properties. That is, the preparation for supplementing the insufficient objectivity that is likely to take place during the process of drafting the standards on changes in current conditions. Thus the author attempts to suggest the analytic method for the decision making related to objective and reasonable determination and regulation of the changes in current conditions through computer based simulation work that considers the cultural properties and surrounding environments under investigation. In order to achieve such research objectives, the author reviewed the subject sites where the cultural property dwarfing phenomenon was expected to occur in case of the permission for the changes in current conditions or where the impact of natural landscape and natural feature on the earth is less than architectural building or artificial structure or where the new policy program is likely to be adopted due to incomplete establishment of current condition change standard within influence investigation area, among other cultural properties with architectural building or artificial structure nearby located in Cheonan city and then selected Cheonansaji Dangganjiju(flag poles) and Jiksanhyun Gwana(government office). The author then undertook the quantitative visibility analysis in order to determine the comprehensive prospect rights for the cultural properties and surrounding environments concerned.

The uniformed regulations for control of the height of buildings owned by individuals to protect landscape of cultural properties are causing serious social conflicts by limiting the development of landowners. It is urgent need of introducing indicators that can resolve such conflicts and evaluate the regulations of buildings, which can satisfy urban development as well as landscape management of cultural properties. Therefore, the purpose of this study is to simulate landscape changes according to the Cultural Heritage Protection Act and National Land Planning and Utilization Act by using Unity3D in the Pungnammun Gate(Treasure No. 308) of Jeonju and its surroundings, where architectural cultural property forms the symbolic landscape of the city. Then some items such as view points, target points were introduced and the quantitative evaluation of landscapes was attempted by applying the indicator of 3D Visual Exposure. As a result, the viewing opportunity and viewing area of Pungnammun Gate were not significantly influenced by changes in landscape according to the two laws. However, the change of the height of buildings by the National Land Planning and Utilization Act, which has the greatest development capacity, confirmed the possibility of weakening the identification of the Pungnammun Gate by increasing 3D Visual Exposure of the background buildings more than two times. Finally, it was confirmed that the skyline of Pungnammun Gate was clearly infringed upon development under the National Land Planning and Utilization Act, but the skyline was maintained similar to the current situation in the regulation by the Cultural Heritage Protection Act. Thus, this study is meaningful in that the application of 3D Visual Exposure showed the possibility of utilization as an indicator for quantitatively evaluating the protection of view on cultural property and skyline according to the changes of building heights.

Recently a method of constructing architectural products using additive manufacturing technology has been proposed. The additive manufacturing technology automates the construction process and it can secure the safety of workers. In addition, due to the high implementation efficiency of atypical shapes, the applicability to the manufacturing process of buildings and infrastructure is drawing attention. Additive manufacturing technology has the ability of satisfying computer-based construction automation, resource management and construction period prediction which is required in the modern construction industry. However, the industrial application is still limited by insufficient data, standards, regulations, and operating methods. In this study, in order to analyze the applicability of architectural additive manufacturing technology, we manufacture each architectural product with two additive manufacturing systems. In addition, we apply an application of each building product into an appropriate manufacturing system through the AM production decision model. And identify problems in the manufacturing process through empirical experiments. As a result, we propose an extended additive production decision model to improve the quality of building products.
