As earthquakes continue to occur in Korea in recent years, seismic evaluation and retrofit of existing school buildings have been carried out. Many domestic school buildings were built using or referring to standard drawings. Therefore, if the overall structural characteristics of a school building can be known first based on standard drawings, it can be provided as valuable data for detailed seismic evaluation. For this reason, this study investigated the weak structural components and failure modes by comparing the strength of beams, columns, and joints constituting standard school buildings constructed in the 1980s. The evaluation was performed for different types of standard drawings and different material strengths. The results showed that the joint was mainly the weakest due to the eccentricity, and the failure modes were partially changed depending on the material strength.

Purpose: Somatotype drawing developed by Sorensen et al.(1983) has been evaluated as a simple instrument of obesity level without real somatic measuring as height and weight. This study was designed to validate somatotype drawings for obesity assessment by bioelectrical impedance body component analysis. Method: At first questionnaire of somatotype drawing was done. Subjects were measured body component by bioelectrical impedance analysis as weight, BMI(body mass index), WHR(waist-hip ratio), body water, protein mass, mineral mass, body fat mass, skeletal muscle mass, soft lean mass, fat free mass and percent body fat. We evaluated correlations between these data and somatotype drawings and tried to grouping of somatotype drawings with the means of major body component value. Result: The data were collected from 205 college women whose height and weight were $161.2\pm4.8,\;55\pm8.3$. Spearman's correlation coefficients of somatotype drawing were 0.74 with BMI, 0.68 with weight 0.69 with body fat mass, 0.65 with WHR. 0.64 with percent body fat after adiusted age. The grade of somatotype drawings were grouped as 1-2, 3-4, 5-6. 7-9 by BMI, body fat mass, weight, 1, 2-4, 5-6, 7-9 by WHR and 1-2, 3-4, 5-9 by percent body fat(ANOVA and Duncan's method). Conclusion: So quick instrument using somatotype drawings were useful tools for evaluation of obesity level and is applicable to screen degree of body fat in self-administered questionnaire survey.

Until 1980s, Korean elementary school architecture has been stereotyped by standard drawings. But there have been very few researches focused on this subject, especially regional one. As an attempt to improve these conditions, this study reviewed standard drawings of elementary school architecture by Education Board of Seoul in 1964 and 1975. Both standard drawings were reviewed through items such as components making a set of standard drawings, floor plan, elevation design and subsidiary facilities. They have rectangular unit classrooms, single-corridor block plan and plain exterior having no symbolic images, which are the characteristics of typical Korean school architecture until 1980s. On the other hand, they reveal the unknown characteristics such as double-corridor block plan, classrooms in basement, toilets of conventional type placed on every floor and changes in details of openings and exterior wall.

This study is a case study for in-house developed Record Maintenance and Management (RMMS) which is a digital data storage/retrieval system in a GIS-enabled solution. RMMS is designed for reorganizing submitted architectural drawings associated with scanned drawings files & geodatabase, managing metadata/table and geometric features in ArcSDE/Enterprise geodatabase format. The birth of the RMMS was borne out of a necessity for a modernized approach in digital file basis to provide improved customer services for various architectural drawings and associated with geo-spatial and its attribute information. Through a case study for building permit & review practice implemented on an internet-based Electronic Architectural administration Information System (EAIS) at the local governments in Korea, this study is able to derive differences between GIS-enabled RMMS system implemented in the Richmond City and internet-based EAIS system implemented in the local government in Korea. In an effort to be the most effective, it presents meaningful ways of maximizing efficiency in record maintenance & management system derived from the case studies that looked into in ways of a method in RMMS' operation, implementation on GIS platform, mutual interface among various programs with various digital files and finally technical supports and system development /upgrade.

With property values of buildings rising, interior construction works are also increasing globally. Interior construction technology has developed into building information modeling(BIM) that can estimate and integrate material quantities. Two-dimensional(2D) drawings and three-dimensional (3D) modeling are becoming a trend owing to the demanding on-site cost and process. 2D drawings and 3D modeling have both advantages and disadvantages that give rise to defects during interior construction work. The field problems, 2D drawings, 3D modeling, and preliminary risk factors of interior construction work were analyzed to identify real problems. Based on the problem analysis, various problems were derived, such as (1) communication with purchasers, (2) communication with workers, and (3) comprehension of the drawings. In this study, a checklist for quality improvement of interior construction was proposed to address the aforementioned issues.

A digital twin is a technology that creates a virtual world identical to the real world. Problems in the real world can be identified through various simulations, so it is a trend to be applied in various industries. In order to apply the digital twin, it is necessary to analyze the drawings in which the structure of the real world to be made identical is designed. Although the technology for analyzing drawings is being studied, it is difficult to apply them because the rules or standards for drawing drawings are different for each author. Therefore, in this paper, we implement a system that analyzes and classifies the vertex detail, one of the drawings, using artificial intelligence. Through this, we intend to confirm the possibility of analyzing and classifying drawings through artificial intelligence and introduce future research directions.

This paper describes the classification problems of the unit modular housing through reviewing design drawings. Modular construction is a new industrialized homebuilding technology that uses large, factory produced modules. In general, more than 70% of construction processes in unit modular construction method are produced in factory after that the modular, which is completed is lifted on site and assembled. This research considers categorization in which the design drawing of the unit module housing can have problems. There are 17 types of construction method and 14 types of design approach as a result of the classification.

To design a drawing at construction sites or ship yards, generally, they exploit CAD program, such as AutoCAD. They also carry the printed drawings in the fields in order to refer the designs. However, the printed designs are easy to be damaged. In this paper, we propose the design of a management system for the CAD drawings on top of the smart operating systems of a smart device. The proposed system exploits the index file based on the Fixed GRID file in order to improve the display speed of the drawings.

It produced a movie to show spectators by interacting the existing famous drawings. It tried a new concept of binding a famous drawing with a person. It recognizes the color of a spectator and the drawings are changed. A spectator is reflected in the work of Marc Chagall. At the same time it is expressed with different BGM that meets the identity of a work. When a spectator moves, the motion is reflected on a work. But without a motion, a work is naturally shown. The four famous drawings are produced to response to Red, Green and Blue of a spectator according to color tracking.

CAD drawings contain drawing errors similar to manually produced drawings. This paper is concerned with a computer-aided drawing check system for the drawing errors. The problem treated in this paper is the checking of dimension errors, deficiency and redundancy of dimension lines in the mechanical drawings made by a CAD system. Graph theory is used for the checking of the deficient and redundant dimensions. The feasibility of this system is confirmed for the checking items.
