국내의 기계 및 설비관련 학과는 모든 산업의 기초가 되는 기계를 다루는 기술인이 반드시 알아야 할 기계관련 이론과 다양한 실기를 통해 산업현장에 필요한 전문직업인 양성에 교육 목표를 두고 있다. 또한 오늘날 첨단 기계 산업의 발달 및 다양화에 따라 생산 및 생산시설 관리, 제품 설계 및 제작, 엔지니어링 마케팅, 컴퓨터 하드웨어 및 소프트웨어 관련 업무를 충실히 담당할 중견 전문가 양성도 담당하고 있다. 본지는 지난해 3월호부터 이번호까지 총 14회에 걸쳐 전국의 기계 및 설비관련 학과를 소개했다. 건축물이 첨단화 다양화 되면서 기계설비의 비중이 점차 커짐에 따라 각 대학들은 다양한 커리큘럼을 마련해 전문성 향상은 물론, 개별 경쟁력 확보를 위해 자격증 및 어학 등을 강화함으로써 21세기가 요구하는 미래의 기계설비인 양성을 위해 노력하고 있음을 엿볼 수 있었다. 본지는 이번호를 끝으로 기계설비 관련 대학 탐방을 마친다. 그동안 취재 및 원고 작성에 협조해주신 대학 관계자 여러분께 감사드린다.

In this study, the small-scale collision experiments using a pendulum principle were carried out to evaluate the safety of the reinforced concrete building selected as a tsunami evacuation building due to the collision of the waterborne debris represented by ships. The experimental parameters were set as impact velocity, mass and length of the drifted ship. In this paper, the maximum impact force, impact duration, impact waveform and restitution coefficient affecting building response were investigated in detail. As a result, the impact force waveforms were distributed as a triangle in most of the experimental results, but became closer to a trapezoid as the length of the collision specimen increased. This is the very important result in calculating the momentum (impact waveform area) affecting building response, Furthermore, the restitution coefficients were constant regardless of the impact velocity, but they varied depending on the mass and length of the waterborne debris. However, the restitution coefficient for the mass per unit length of the waterborne debris can be evaluated.

최근 고강도화 기술이 발전함에 따라 각국에서는 지역마다 랜드마크로 불리는 건축물들이 자주 등장하는 것을 문헌을 통하여 자주 접한다. 또한 건축물의 거대화 고층화에 따라, 합리적인 설계를 가능하게 하는 콘크리트의 경량화가 새로운 과제로 주목을 받고 있다. 초경량 콘크리트 구조물을 실용화 할 수 있으면 상부구조의 경량화, 지진하중의 저감, 건설기계의 생력화, 기초 부담의 저감 및 기초의 경량화 등에 따라 건설콘스트 에너지 전체의 저감에도 큰 효과가 기대되기 때문이다. 국내에도 경량 골재에 대한 제조가 간헐적으로 계속되어 오고 있다. 특징을 보면 산업부산물을 이용한 친환경소재, 에너지 절감, 흡수율 등을 대폭적으로 낮추었다고 소개되고 있는 반면, 비중을 초경량화한 경우는 거의 없다. 따라서 본 검토는 절건비중이 1.0 미만인 초경량골재를 사용한 경우로 비록 실험실적 결과이지만 쉽게 접할 수 있는 제품이 아닌 것 같아 아소(麻生)공과대학 미즈다(水田)교수의 논문을 소개하는 것이고, 콘크리트 테크노 2009년 1월에 게재된 문헌을 요약 발췌한 것임을 밝혀둔다.

The more demands on efficient utilization of resources, the more structural engineers prefer to select remodeling to improve old building's capacity. A series of four shear wall specimens were tested under constant axial stress and reversed cyclic lateral loading in order to evaluate the effect of the opening on the lower center of the wall induce by remodeling. Consequently, the existence of opening was verified to induce a different failure, which was caused by reduction of compression strut area formed on the wall to diagonal direction. Especially, the ultimate strength of the wall with an opening was revealed approximately 35% lower than that of the wall without an opening. And the similar results were appeared in characteristics of stiffness and energy dissipation capacity.

University campus plans include urban and spatial values and identities that they emphasize. The purpose of this study is to analyze sustainable campus policy, space, and the application to architectural planning, which UBC in Canada pursues independently from a Green Campus Certificate System. Sustainable directions and architectural components are deduced. The results are as follows: 1) the correspondence between the campus plan's goal and architectural implementation is the most important. Thus, the university must build a system for the plan's goal and a strategy to make a sustainable campus. 2) A guideline and system are requested to make many experts in various fields and stakeholders participate in the initial stage through "Design Charrette." 3) A system of virtuous circulation must be built so that feedback can be applied through the real-time comparison and verification of building energy consumption. Another goal of this study is emphasizing the necessity of campus policy and plans based on the "Living Laboratory" concept to make a sustainable city. This study could be meaningful because it supports a basis for triggering the establishment of goals for a sustainable plan and implementation in Korean universities.

Front columns of buildings were most severely damaged by insects. Hole diameter damaged by insects were different in each location on columns, that is, bottom, middle position, or top of columns. That mean various insects attacked on columns of wooden traditional buildings because kinds of each insect depends on the hole diameter. Specially, middle position of columns were harmed seriously. Hole diameters damaged by insects were various from 1 mm to 10 mm, but approximately 5 mm diameter was found most commonly.

In this paper, the problems and betterment plan in operating district units plan are studied by selecting typal case locations based on the types of district units plan of the city of Busan. According to the types, 4 locations of 'type of maintaining preexisting district' and 3 of 'type of managing preexisting district' are selected as case locations, based on a scale and characteristics of each location.In systematical aspects of the case locations, indiscreet upward adjustment of the locations, insignificant participation of the citizens and patternization were recognized as problems. And setting accurate standards for target and range of alteration in line with usage plan of the locations would be necessarily urgent. So through the analysing process of the problems arisen from the case locations I would suggests necessary solutions to improve the effectiveness of the district units plan. And In planning aspects, the similarity between the basic directions and the object, batch-application of the density plan, inadequacy of the usage plan, allocations and patterns of structures, and color planning were recognized to have problematic points. Consequently distinguished specific operating-guidelines would be necessary to achieve the basic directions and the object of district units plan. Furthermore, the building-to-land ratio and floor space index are needed to be exactly calculated through providing accurate and logical standards for appropriate development density of structures.

In order to accommodate the increase in urban population due to government-led national planning and economic growth, many buildings such as houses and business building were supplied. Although the building law was revised and managed to manage the supplied buildings, for the sake of economic benefit, there have been buildings that are enlarged or reconstructed without declaring building permits. In order to manage these buildings, on-site surveys were conducted. but it has many personnel consumption. To solve this problem, a method of using a satellite image and a manned aircraft is utilized, but it is diseconomical and a renewal cycle is long. In addition, it is not utilized to the height, and although it is judged by the shading of the building, it has limitations that it must be calculated individually. In this study, height of the building was calculated by using the unmanned aerial vehicle with low personnel consumption, and the accuracy was verified by comparison with the building register and measured value. In this study, spatial information was constructed using a fast unmanned aerial vehicle with low manpower consumption and the building height was calculated based on this. The accuracy by comparing the calculated building height with the building register and the actual measurement.
