The quantity bill writing of organized electrical construction can be an effective to quality and process management in the construction. Therefore, in order to overcome confusion of the construction and doing an effective work, the clearly quantity bill writing is need. This paper is a focused to solve a problem of existing quantity bill as the difference in terms of work section and item information, regulatory information of ordering authority. Therefore, a terms of work section and item information, regulatory information of ordering authority has been normalized. Moreover, basic data of simplification for quantity bill writing and structure has been guaranteed.

One of the important features of the advanced nuclear power plants is the system simplification. In this work, a model has been introduced to quantitatively evaluate the system simplification. A few models have been developed for quantitative evaluation of design simplification and the design enhancements of CVCS of the advanced reactors have been evaluated with models based on the entropy concept and the system availability. In addition, operational interface of CVCS with peripheral systems has been considered to develop a new evaluation model in this work. The quantification results for the design of the System 80+ and KSNPP indicate that the simplicity of the CVCS is primarily dependent on the type and number of charging pumps.

Recently, in computer graphics, researches on 3D animations have been very active. one of the important research areas in 3D animation is animation of human being. The creation and animation of 3D facial models has depended on animators' manual work frame by frame. Thus, it needs many efforts and time as well as various hardwares and softwares. In this paper, we implements a way to generation 3D human face model easily and quickly just with the front face images. Then, we suggests a methodology for mesh data simplification of 3D generic model.

In this study, we reviewed the main strategies and contents of the work style innovation promoted by the Moon Jae-in government, and analyzed the contents and success factors of the work innovation based on the case of a specific local government. In particular, this study analyzes the case of innovation in the way of working through simplification of work, and the local governments, which were the subject of the study, received excellent evaluation in the government innovation evaluation of the Ministry of Public Administration and Security in 2019. In this study, we conducted in-depth interviews with employees of local governments to examine the problems, achievements, and success factors related to business simplification. First, it was found that it is very important to form consensus so that the members of the organization can participate in the change in order to simplify the task. Second, incentives, such as HR, were needed to induce active participation of members in the innovation project called Simplification of Work. Third, in order to induce and support organizational change, it was found that the interest and support of middle managers and directors were the most important factors. The results of this study will help to prepare the policy for innovation in the public sector's working style.

The quadratic error metric (QEM) algorithm has been frequently used for simplification of triangular surface models that utilize the vertex-pair algorithm. Simplified models obtained using such algorithms present the advantage of smaller storage capacity requirement compared to the original models. However, a number of cases exist where significant features are lost geometrically, and these features can generally be preserved by utilizing the advantages of the curvature-weighted algorithm. Based on the vertex-based geometric features, a method capable of preserving the geometric features better than the previous algorithms is proposed in this work. To validate the effectiveness of the proposed method, a simplification experiment is conducted using several models. The results of the experiment indicate that the geometrically important features are preserved well when a local feature is present and that the error is similar to those of the previous algorithms when no local features are present.

The rebar work is very related to the safety and durability of the building. Recently, the rebar work is produced some serious problems due to the lack of skillful crafts-man and the rising cost of rebar materials. Many papers have dealt with the rebar work of the manufacturing system in plants with a view to improvement those problems. But, the research on the rebar work of the manufacturing system in field is in a insignificant condition. This study presents the following improvement schemes as a result. First, the education strengthening for evaluation on practical affairs, second, the reinforcement of drawing & management in shop drawing and finally the simplification of apartment rebar work in slab. Also, this paper aims at advancing apartment rebar work by the actual condition survey in slab work. The further research will be needed about the whole structure parts such as foundation, wall, girder and rebar truss-deck plate as one of the improvement methods.

An integrated approach of model simplification for high burnup spent nuclear fuel is proposed based on material calibration using optimization. The spent fuel rods are simplified into a beam with a homogenous isotropic material. The proposed approach of model simplification is applied to fuel rods with two kinds of interfacial configurations between the fuel pellets and cladding. The differences among the generated models and the effects of interfacial bonding efficiency are discussed. The strategy of model simplification adopted in this work is to force the simplified beam model of spent fuel rods to possess the same compliance and failure characteristics under critical loads as those that result in the failure of detailed fuel rod models. It is envisioned that the simplified model would enable the assessment of fuel rod failure through an assembly-level analysis, without resorting to a refined model for an individual fuel rod. The effective material properties of the simplified beam model were successfully identified using the integrated optimization process. The feasibility of using the developed simplified beam models in dynamic impact simulations for a horizontal drop condition is examined, and discussions are provided.

The rate of accidents in the domestic construction industry is on the rise, which is 1.9 times higher than in other industries in 2018. The increasing trend of construction accidents shows the limitation of the current construction safety management system, and enhancement of the effect to prevent accidents in the construction industry is required through carious measures for improvement. This paper aims to increase the efficiency of safety management in the construction industry by deriving standard safety management tasks to prevent accidents in the construction industry and deriving document simplification and importance based on IPA analysis results.

In the mobile environments for the vector map services, a map simplification work through the map generalization steps helps improve the readability of the map on a large scale. The generalization operations are various such as selection, aggregation, simplification, displacement, and so on, the formal operation algorithms have not been built yet. Because the algorithms require deep special knowledge and heuristic, which make it hard to automate the processes. This thesis proposes some map generalization algorithms specialized in mobile vector map services, based on previous works. We will show the detail to adapt the approaches on the mobile environment, to display complex spatial objects efficiently on the mobile devices which have restriction on the resources
