Data on basic properties are needed due to the increased interest of insulation materials, but In Korea, there are fewer data related to the basic properties of insulation. so the absorption rate was measured every seven days by selecting some of the insulation among insulation materials to provide basic data on absorption rates among basic properties. Measured over 43 days, both absorption and weight showed the highest PF levels, other insulation is judged to have almost reached the maximum absorption rate. PF is still an increasing trend and requires constant observation.

소비자들이 필요로 하는 다양한 제품을 생산하기 위하여, 제조 현장에서 사용하는 자동화 장비의 종류가 다양해져가고 있다. 자동화 장비는 일반적으로 운영자가 효율적으로 감시하고, 조작할 수 있도록 사용자용 인터페이스 장치(HMI)를 설치하여 제작되고 있다. HMI 장치는 자동화 장비마다 개별적으로 고정되어 있기 때문에, 운영자가 다양한 장비를 즉각적으로 조작하기에 어려움이 존재한다. 본 논문에서는 모바일 장치를 사용해 QR코드로 장비의 화면을 표시하고, 원격으로 해당 장비를 조작할 수 있는 모델을 제안한다. 제안 모델은 하나의 모바일 장치를 활용하여 다양한 자동화 장비를 원격으로 신속하게 감시하고 제어할 수 있어, 제품 생산에 대한 효율이 증대될 것으로 기대된다.

Curtain wall means a non-bearing wall that forms the outer walls of a building to divide the exterior and interior space. The increased use of curtain walls is diverse, including structural safety, watertightness, and wind pressure. As the government's energy conservation policy and the aim of zero-energy houses, the importance of heat reduction is also greatly increased. So, the study of monotony is constantly being conducted. Thus, in this study, insulation performance was analyzed through simulation according to the shape of curtain wall and the shape of insulation inside, and the purpose of this study was to provide basic data on the application of insulation criteria by energy saving design of buildings.

Curtain wall is constructed in various forms and designs by forming the exterior walls of a building, and refers to non-bearing walls that divide the exterior and interior spaces of a building. Curtain walls require not only wind pressure, but also waterproof, insulation, insulation, and durability, as well as the effects of recent frequent earthquakes. Studies on the sleeve used to connect the vertical member mullions in the process of high-rise curtain walls are insufficient. In this study, sleeves connecting curtain wall mullions were developed to absorb external displacement, and the purpose of this study was to evaluate economic feasibility through comparison with existing construction methods.

Since natural sand is being depleted, research is being conducted to use glass similar to sand as an aggregate. When non-reusable waste glass is crushed and used as fine aggregate, it is known that alkali of cement and silica of glass react to cause an alkali aggregate reaction. The purpose of this study is to provide basic data by studying the strength according to color to use waste glass as fine aggregate. When 10% was replaced, both flexural and compressive strength showed strength values similar to those of Plain. When replaced by 20% and 30%, the 7-day intensity was higher than that of Plain. In addition, colorless glass was found to have the highest strength among glass colors. More research is expected to be needed to become a fine aggregate of waste glass.

In the event of a fire in the lower space, a high temperature of 1000℃ or more and an explosive fire may occur due to the closed structural features and combustible materials. On the other hand, more than 90% of oyster shells are made of CaCO₃, and when heated to about 700℃ or higher, CaO and CO₂ is generated due to decarboxylation reaction. In this study, we try to infer the amount generated by CO₂ changing the weight of mortar using oyster shells as fine aggregates after heating. in conclusion It is considered that the smaller the particle, the greater the decarboxylation reaction and the greater the weight change.

The use of converter slag as an aggregate for concrete is limited due to the risk of expansion. This study analyzed the substances causing the expansion of converter slag and evaluated the possibility of its use as an aggregate for concrete through separation and selection. As a result of the experiment, it was confirmed that CaO and MgO were concentrated in the slag particles inducing expansion, and it was confirmed that it was possible to separate them from non-expanded particles through magnetic.

정부는 공공데이터 개방을 통해 신산업, 일자리 창출 등 경제 활성화를 위한 도구로 활용하는 것을 목표로 한다. 정부는 고품질의 공공데이터 보유를 위하여 품질 개선 활동을 통해 공공데이터 품질 향상을 진행하고 있다. 그러나 공공데이터 품질관리 수준 진단을 진행하는 담당자의 데이터에 대한 전문성과 이해도에 따라 품질진단 결과에 격차가 발생하여 진단 결과의 신뢰성을 보장하기 어렵다. 본 논문은 공공데이터의 원활한 품질진단 지원을 위해 품질진단규칙 매핑 모델을 제안하여 공공데이터 품질진단의 안정성과 신뢰성을 높인다.

본 논문에서는 서울특별시 청소년들을 위해 버스 차내 혼잡을 완화하기 위한 단거리 버스 노선을 제안한다. 버스 이용률이 높고 청소년 거주 비율이 높은 행정구역을 선정 후 등교 시간에 승하차량이 많은 구간과 차내 혼잡이 학교 인근까지 이어지는 노선을 추출하였고, 이를 기반으로 새로운 단거리 버스를 제안한다. 최종적으로 선정된 노선은 단방향 수요가 강해 Dijkstra Algorithm을 이용하여 최단 거리 공차 회송 노선을 선정하였다.
