The perimeter zone is space which receives a significant effect of ambient condition, it is necessary to improve the thermal performance in order to building energy saving. For this reason, a lot of study about the active approach is being performed, such as perimeter-less air conditioning system. But the performance of the perimeter zone is necessary to improve, through the passive approach. Therefore, the purpose of this study is to provide basic materials of energy-saving design of perimeter zone, based of the PAL that simulation changing the thickness of insulation and the rate of windows.

Flexible composite propellers have a relatively large deformation under heavy loading conditions. Thus, it is necessary to accurately predict the deformation of the blade through a fluid-structure interaction analysis. In this work, we present an LST-FEM method to predict the deformation of a flexible composite propeller. Here, we adopt an FEM solver called OOFEM to carry out a structural analysis with an orthotropic linear elastic composite material. In addition, we examine the influence of the lamination direction on the deformation of the flexible composite propeller.

현재 국내에 체류하는 외국인 수가 150만 명에 이르고 있으며 그 수는 꾸준히 증가하고 있다. 이처럼 한국사회가 다문화사회로 진입함에 따라 일선 도서관에서 제공하는 다문화서비스가 중요해졌기 때문에 다문화자료실과 다문화프로그램도 증가하고 있다. 그러나 서비스 제공을 전담하여 전문적으로 제공할 인력은 충분하지 않다. 본 연구에서는 다문화자료실 혹은 다문화프로그램을 운영하는 도서관의 다문화서비스전문사서 현황과 문제점 등을 알아보고 앞으로의 발전 방향을 모색하고자 한다.

Increased density of racks has resulted in increased use of data center cooling energy and the needs for energy efficient cooling systems has increased. In response to these needs, ASHRAE presented a performance indicator, which is Mechanical Load Component (MLC), for the purpose of evaluating systems at the design stage. However, the MLC metrics presented in the current standard can only be determined for system compliance and compared alternative systems with the system configuration completed. Therefore, there are limitations to considering MLC from the early stages of design. In this study, to extend the scope of application of MLC in the design phase, the design factors of the main equipment comprising the cooling system are classified by the MLC load component and interrelations between design factors were identified.

Cases of repeated acute gastric dilatations after binge eating in one patient are rarely reported. We report here a case of repeated acute gastric dilatations in a 22-year-old woman with bulimia nervosa. Her repeated acute gastric dilatations seem to have been related to superior mesenteric artery syndrome. On her last visit due to acute gastric dilatation, she underwent emergency gastric decompression surgery because of abdominal compartment syndrome; however, she eventually died because of ischemia reperfusion injury. Emergency physicians should be aware of the need to manage acute gastric dilatation in patients with eating disorder and should pay attention to the signs and distinctive clinical features of abdominal compartment syndrome.

최근 딥 러닝 분야의 기술이 발달하면서 Chat GPT, Google Bard와 같은 자연어 처리 기술이 확대되고 있고 이미지 객체를 분석하는 CLIP, BLIP와 같은 기술도 발전되고 있다. 그러나 전시회와 같은 예술 분야는 딥 러닝 기술 기반의 이미지 데이터 활용이 제한적이다. 본 논문은 전시회장에서의 그림 내부의 객체 데이터를 분석하기 위해 이미지 객체 분석 기술을 사용하고 자연어 처리 기반으로 관람객이 특정 그림에 대한 질문을 입력하면 해당 그림을 식별하는 방법을 제시한다. 이를 통해 관람객이 원하는 그림을 선별하여 관람할 수 있도록 한다.

Recently, with the digitalization of the construction industry, free-form building construction technology is developing. However, the technology for manufacturing free-form concrete panels is still insufficient. In this study, the surface error of the FCP according to the thickness of the lower silicon plate, which is a component of the existing lower multi-point press, was analyzed in order to manufacture a precise FCP. As a result of the analysis, it was found that the thinner the thickness, the larger the error value. These results can be used as a basis for existing research and are expected to be used for research on high-quality FCP manufacturing technology.

Free-form Concrete Panel(FCP) is each panel that composes the concrete exterior skin of Free-form building. FCPs contain curved surfaces, and FCPs have different curvature, size, and angles. In order to manufacture FCP, high technology is required, and it is currently difficult to manufacture it according to the design shape. In particular, many errors occur in the side shape of FCP. This is because when the side silicone mold is applied, it is installed without a coupling method between molds and support device. In this study, basic research was conducted to develop a side silicone mold support device to solve the above problems. We classified the required performance and derived the detailed requirements. Also, Based on this, we drew the basic design of the support device. We plans to conduct design improvement, mock-up making, and FCP manufacturing experiments through future research.

Free-form buildings have a curved shape and are composed of geometric shapes, which require high precision. Therefore, this study proposed a new extrusion method, a piston method, that improves the precision of FCP by automatically extruding a predetermined amount of concrete by improving the aforementioned limitations. The technology to extrude a predetermined amount of concrete by applying pistons is expected to shorten construction period and increase economic efficiency by improving the precision and productivity of free-form panels.
