건설분야 전자매뉴얼은 기존에 서술적 문서형태로 작성되어온 시공법, 유지관리절차 등에 관련된 시방규정, 지침서들이 시각화를 위한 멀티 미디어 기능과 통합연계정보 제공기능을 갖는 전자적 형태로 구성된 것을 의미한다. 이러한 전자적 개념의 건설전자매뉴얼은 지침 규정의 전자화는 물론이고, 공사관리자의 이해도 증진을 위해 해당 규정에 관련된 3D동영상 화면과 가상현실, 시공이력사진 정보들을 연계해서 제공해 주는 종합 정보시스템 개념을 갖고 있다. 현재 시방정보, 관련법규 등의 건설분야 각종 지침들은 전자화를 위한 표준적 인 규칙 이 없이 일반적 인 문서형 태로 작성되고 있으므로, 관련정보의 체계적인 축적 및 공유가 어렵고 효과적 인 시설물의 시공 및 유지관리에 장애요인이 되고 있다. 본 연구에서는 기존 건설분야 정보화 체계와 비교하여 전자매뉴얼의 필요성과 타 분야 전자매뉴얼대비 건설전자매뉴얼의 특성을 분석하여 건설분야에 적합한 구성전략을 제시함으로써, 건설분야 전자매뉴얼의 활용도를 인식시키는데 연구목적이 있다. 이를 위하여 본 연구에서는 유지관리업무 전자매뉴얼 시안을 포함하는 시설물 재해관리용 전자매뉴얼의 적용성을 가상적으로 구성하여 검증하고 있다.

Many government agencies have used domestic deacidification equipments to stabilize archives; however, no agency has verified archives' current preservative status. We studied the Nara National Archives' documents that had treated by mass deacidification process from 2001 to 2012, in order to examine the documents' preservative status and how efficient the mass deacidification has been. Approximately 1% of total 112,970 Nara National Archives' documents treated by mass deacidification were randomly selected and evaluated on their current measure of acidity and color change. Regardless of the kinds of document material, a wide range of pH level was found. Especially those documents that were treated by mass deacidification equipment after 2006 showed acidic conditions that were less than pH 6.8 level. Those documents were probably not treated properly by deacidifying chemical because of tightly packing style. The current measures of acidity and color records will be useful as a reference for future evaluations of further decay of the documents. It was the first study to evaluate acidity and color conditions of Nara National Archives' documents treated by mass deacidification equipment. We concluded that when using mass deacidification equipment, archives should not be loaded tightly in order for them to be fully in contact with deacidifying chemical.

Increasing energy costs have caused profitability problems for paper suppliers. Therefore unprofitable lines are being closed down. The actions aiming for improved profits are focused either on cost savings or on increasing the capacity of the remaining machines. The runnability of a paper machine and its total efficiency have a significant effect on energy consumption. Producing one ton of waste paper consumes at least as much energy as producing the same amount of sellable end product. New automation solutions enable significant cost-effective improvements to the total efficiency of a line without large investment projects. The measures focus on minimizing changes, interruptions, interruption recovery times and grade change times. Newest actuators, online quality measurements and wet end analysators create an improvement potential, which can be optimally implemented with the latest machine direction control solutions, based on model predictive control concepts. Equally, drying management is significant to the energy consumption. The newest control strategies optimize the use of various drying actuators for different situations; either by responding to changes as efficiently as possible or by using only the cheapest energy sources in stable situations. An even steam supply, which is vital for paper machines, is achieved with control for the power plant steam network. This makes possible to avoid the delays upon starting the paper machine and assure an even steam supply for the drying section and the actuators. This document describes means which have brought significant energy and raw material savings for paper machines. Metso Automation has provided efficiency improvement packages, which are usually based on optimized control of dry weight and drying in all running conditions. The solutions are based on performance analysis, on which the estimations for improvement potential and the necessary actions are based on. Typically benefits on an annual level have been from hundreds of thousands of euros to over one million euro. For example, variations in dry weight have been decreased more than 50%. The results are presented with a few examples. Additionally, the analysis models, adjustment solutions and the changes in running methods with which the results were achieved, are presented.

최근 의료서비스 환경에서 진료정보 교류는 의료의 안정성 및 질 증대, 진료업무 효율성 향상, 의료기관 운영 효율성, 환자의 편의성 증대를 가져올 수 있는 필수 의료 서비스 모델이다. 하지만 의료기관별 정보화 수준이 다양하고, 표준화된 시스템이 마련되어 있지 않으며, 기관별로 서로 상이한 정보시스템이 구축되어 있어 실질적인 진료정보 교류가 어려운 상황이다. 이 논문에서는 국내 법제도 안에서 진료정보 교류를 활성화 하기위해 관련 기술표준 및 진료정보 교류 모델에 대해 분석하였고 이중 가장 이상적인 지연 응답 모델을 기반으로 보다 나은 성능 개선을 위하여 진료정보 교류 프레임워크를 설계하였다. 성능 개선 진료정보 교류 프레임워크는 진료정보 교류 시 메타데이터 플로우와 실제 CDA 문서 플로우를 구분하여 기존 지연 응답 모델 기반 시스템과의 성능 비교 실험 결과 약 24%의 성능 향상을 얻었다.

In Korea, local government officials are in charge of buildings, and as such are supposed to review submitted documents related to the architectural administration to ensure that they comply with the legal standards. However, these officials generally put a greater emphasis on the preparation of the set of documents required for the administrative work than the content the documents contain. For this reason, many experts point out that the shortage of officials specialized in buildings and construction, as well as the lack of expertise among the building officials in the local governments, may result in repeated safety accidents during building construction. The purpose of this study is to propose the operational direction of a Regional Building Safety (RBS) center to secure the performance and safety of buildings by utilizing private resources. In this study, we carried out a pilot project to verify the effects of an RBS center and to derive the specific number of experts required. As a result, the technical matters were resolved in approximately 15% of the total cases of the document processing procedure, and the level of technical specialization among the officers has also been improved through the provision of guidance. The research findings support the validity and effects of the introduction of the RBS center. Finally, this study proposes (1) the types of RBS Centers that should be established, (2) the roles and business scope of the RBS Center, (3) the specific number of experts required, (4) the qualifications of the experts, and (5) the business regulations of the RBS Center.

This article describes a simple and cost effective fabrication procedure by using hand lay-up technique that is employed for the manufacturing of thin-walled axi-symmetric composite shell structures with carbon, glass and hybrid woven fabric composite materials. The hand lay-up technique is very commonly used in aerospace and marine industries for making the complicated shell structures. A generic fabrication procedure is presented in this paper aimed at manufacture of plain Carbon Fabric Reinforced Plastic (CFRP) and Glass Fabric Reinforced Plastic (GFRP) shells using hand lay-up process. This paper delivers a technical breakthrough in fabrication of composite shell structures without any joints and wrinkling. The manufacture of stiffened CFRP shells, laminated CFRP shells and hybrid (carbon/glass/epoxy) composite shells which are valued by the aerospace industry for their high strength-to-weight ratio under axial loading have also been addressed in this paper. A fabrication process document which describes the major processing steps of the composite shell manufacturing process has been presented in this paper. A study of microstructure of the glass fabric/epoxy composite, carbon fabric/epoxy composite and hybrid carbon/glass/fabric epoxy composites using Scanning Electron Microscope (SEM) has been also carried out in this paper.

This paper is about environment-based low-code and no-code execution platform and execution method that combines hybrid and native apps. In detail, this paper describes the Low-Code/No-Code execution structure that combines the advantages of hybrid and native apps. It supports the iPhone and Android phones simultaneously, supports various templates, and avoids developer-oriented development methods based on the production process of coding-free apps and the produced apps play the role of Java virtual machine (VM). The Low-Code /No-Code (LCNC) development platform is a visual integrated development environment that allows non-technical developers to drag and drop application components to develop mobile or web applications. It provides the functions to manage dependencies that are packaged into small modules such as widgets and dynamically loads when needed, to apply model-view-controller (MVC) pattern, and to handle document object model (DOM). In the Low-Code/No-Code system, the widget calls the AppOS API provided by the UCMS platform to deliver the necessary requests to AppOS. The AppOS API provides authentication/authorization, online to offline (O2O), commerce, messaging, social publishing, and vision. It includes providing the functionality of vision.
