In construction of RC buildings, the quality of shop and detail drawings is very essential for the quality and safety of buildings, Nevertheless, most of thess works are left to site workers and the requirements about bar detailing such as anchorage and splice have been done without rational design and engineering. The purpose of this research is to develop a computer aided drawing system of rebars for RC buildings. The system is based on an integrated structural design system, that is SDP. SDP manages an engineering database for structural design information. It provides all the information needed to draw rebar drawings. The drawing system consists of three modules, 1) Structural Plan Drawing System, 2) Shop Drawing System, and 3) Detail Drawing System. It is expected that not only the productivity of detail drawing works but also the quality and safety of buildings will be improved using the rebar drawing system developed in this research.

Warehouses and Self-Storage facilities are essential for e-commerce operations, providing inventory, distribution, and delivery space. As per the Bureau of Labor Statistics, the number of warehousing and storage businesses in the United States increased from 15,152 in 2010 to 20,002 in 2021, showing continuous growth over the decade. Given the recent surge, there is a need to better understand the impact of these delivery methods on the quality metrics of these facilities. This study aims to contrast the measure of quantitative quality performance of design-build (DB) versus traditional design-bid-build (DBB) project delivery methods (PDM) for warehouses and self-storage facilities. This research conducted a literature review to document quality metrics to compare DBB and DB on project performance. ANOVA was conducted to compare the significant difference between the means to compare the performance between delivery methods and project outcomes across these critical areas. With these insights, owners can make informed strategic decisions about selecting the optimal PDM for future storage facility projects based on their unique quality and scope management objectives.

Korean academic societies in science and technology are trying to improve the prestige and quality of their journals by enlisting them in international citation databases. In order to be enlisted in international citation databases, a journal should be managed and maintained according to the policies of organizations operating citation databases. In particular, a journal should have an effective on-line publishing process including fair and transparent peer-review. KISTI studied the systematical necessary element so that the domestic journal could receive the evaluation for the international index DB record. Based on this, KISTI designed the Article Contribution Management System(ACOMS) Ver. 4.0 including the academic journal homepage and completed the english ACOMS development in 2010. Presently the english ACOMS promotes the continued facility improvement in 2012 in order to be reborn as the international journal manuscript submission/review and electronic publishing system. And it is managed about the academic journal of 49 kinds including JICCE academic journal. Therefore, this paper suggests utilizing english ACOMS as a way for JICCE journal to enlist their journals in international citation database.

The latest parceling-out price upper limit ancestor memorial service enforcement, Sale in lots circle is elated interest of society each floor for construction working expenses by open etc. but private investment law for society basis facilities, because circle that is presenting in parceling-out price upper limit ancestor memorial service back is different system (configuration item), cross is expected. A lot of study results connected with cost control expense arbor in the mountains etc. were presented until present, but persistent DB expulsion prohibition. Cost information is standardization unpreparedness of system. It is real condition that is hoarded since research and development by practical use plan presentation unpreparedness etc. Therefore, in this study, desire does actual date use plan presentation by purpose through DB construction after process by information form of good quality so that can collects efficiently and manages and utilizes at construction production step flag firm' s results data which is achieved. Can utilize to data of tool development that maximize ultimately comprehension about employer' s business and business order ability through persuasion, and diverts in cost control business hereafter.

Purpose: In this paper, we have dealt with problems of army supply system for eyeglasses and improvement plan. Methods: We collected the latest service request of MND (Ministry of National Defence) and case of U.S. Army and analyzed the data. Results: We treated contents, construction methods and plans for efficient use of vision DB (database) for Korean Army. We suggested several alternative proposal for eyeglasses supply system which made possible quicker delivery of eyeglasses to the soldiers and increase satisfaction. Conclusions: The Korean Army must construct vision DB to service high quality vision service to the solider. It is urgent that the Korean Army set up a unit to take charge of vision management and service. And the Korean Army need to upgrade supply system for eyeglasses.

Many researchers have developed a series of vision-based technologies to monitor construction sites automatically. To achieve high performance of vision-based technologies, it is essential to build a large amount and high quality of training image database (DB). To do that, researchers usually visit construction sites, install cameras at the jobsites, and collect images for training DB. However, such human and site-dependent approach requires a huge amount of time and costs, and it would be difficult to represent a range of characteristics of different construction sites and resources. To address these problems, this paper proposes a framework that automatically constructs a training image DB using web crawling techniques. For the validation, the authors conducted two different experiments with the automatically generated DB: construction work type classification and equipment classification. The results showed that the method could successfully build the training image DB for the two classification problems, and the findings of this study can be used to reduce the time and efforts for developing a vision-based technology on construction sites.

This study aims to development of web-based process management system for spatial data construction. For developing this system work classification of basic surveying was standardized and quality management method for spatial data was established. Production process and work classification system for basic surveying such as control point surveying using GPS, leveling, aerial photographing, digital mapping, topographic mapping, digital elevation modeling, aerial photographic DB construction and digital orthophotomap was standardized. The status of the output and quality inspection for basic surveying project were analyzed, and the elements of quality inspection and data format for the type of outputs were analyzed. Based on standardized and analyzed contents, web-based process management system was developed after database and process was designed. The process management system consisted of process management, quality control, metadata management, and system management.

For analyzing the qualitative and quantitative analysis of fuel marker in petroleum products, the applicability of HPLC was studied. For the qualitative analysis of fuel marker in kerosene and automotive diesel, optimal analytical conditions(ratio of mobile phase solvent, flow rate, etc) in HPLC were selected and calibration curve for quantitative analysis of fuel marker was prepared based on the result of qualitative analysis. In particular, the correlation coefficient of calibration curve in kerosene and automotive diesel was shown to be 0.999 in a certain concentration range and it could be applied to the quantitative analysis. The results of analysis using the UV/Vis spectrometer, which is the current analysis method of fuel marker, were compared with the analysis results using the HPLC. The kerosene showed a low deviation of about 7 % and the automotive diesel showed a somewhat large deviation of about 20 %.

일반적으로 음성 합성용 데이터 베이스에서는 고음질을 유지할 수 있는 파형 부호화법을 주로 사용한다. 그것은 파형 부호화법이 발성자의 개성과 메시지 정보를 보존하기 때문에 음질의 명료성이 우수하기 때문이다. 그러나 기존에는 파형 부호화법을 적용해서 음성 파형 자체의 잉여성분만을 제거한 후 합성용 데이터 베이스로 사용하기 때문에 음성 합성용 데이터 베이스의 크기가 커지는 단점을 가진다. 따라서 본 논문에서는 이러한 단점을 극복하기 위해서 기존의 운율조절법을 통해서 음성 합성용 데이터 베이스를 압축하는 방법을 제안한다. 결과적으로 제안한 방법을 사용함으로써 고음질을 갖는 음성 합성용 데이터 베이스를 가질 수 있었고 데이터 베이스의 크기도 줄일 수 있었다.
