The full containment Liquefied Natural Gas(LNG) storage tank is based on a double liquid container concept : two separate containers, one within the other, are capable of containing the LNG. The outer concrete tank provides comer protection(secondary containment) to withstand and safely contain any spill from the inner tank. The comer protection is installed on inside corner surface of outer concrete tank. Because of high and complex stresses, corner protection is designed by ASME section ⅧI Div. 2, Appendix 4 on behalf of API 620 which is main design code for LNG tank. Design guidelines to determine design factors such as liner thickness and knuckle radius are not well understood because Appendix 4 is the design method not based on equation but FEM. Recently, the volume of LNG tank shows a tendency to increase. So it is necessary to set up the design guidelines to cope with change of LNG tank capacity and height/diameter ratio. In this paper, optimum design of corner protection was performed and the design guidelines were suggested by the results of FEM for LNG tanks which have different capacities and height/diameter ratio.

The interior designs and architectures are definitely important to the disabled because it could improve their independence considerably. Although the design is meaningless if for each disabled's symptom is not considering, the research on design to support detail symptom of each disabled is insufficient. This paper studies the bathroom in house for the disabled of hemiplegia after a stroke. The bathrooms is important space that cause many unnecessary activities and accidents without carefulness. Study method makes framework through principle of universal design and feature of hemiplegia after a stroke. We visit three places where the disabled live in and used qualitative analysis. After checking the present condition of the bathroom, a request and necessity of the disabled through observation and semi-structured interview. According to the result of this study, the obstruction factors were increased when the disabled try to use both hands or to reach and pick up objects, to move and to assist the severe disabled in the bathroom. Finally this study suggests design guidelines based on principle of universal design and factors for better bathroom design for the disabled.

Stone is one of the oldest material for construction and artistic works. This study investigates the current use of stones in landscape constructional works, and the design criteria to advance the arts of natural stone arrangements. Thirty four experts and thirty two others were surveyed with various photos of simulated construction works of natural stone arrangements fond improved design guidelines. Major findings are as follows: -The payment for the use of stones ranges approximately 5 to 10% of total cost of landscape constructional works. More stones may be used when better retailing system is introduced, working skill is standardized, and more of the substitute natural stones made of blasted rocks are provided and the cost goes down. -Preferences showed little difference for the mixed use of different sizes, colors and shapes of stones, and for the use of similar ones, in the construction of walls. This does not match with the current design guidelines. -Arranging three stones, which symbolizes heaven, earth, and human being, was the most preferred. As the supply of natural stones is limited and more substitute stones are used, it its needed to establish guidelines for the production of substitute stones. -Grasses are much more preferred between pavement stones than mortars. -In current practices, top of piled up natural stones is usually arranged level. More freely curved top lines are preferred to straight line.

Currently with the continuous development of ceramic and cementation materials, CAD-CAM(Computer-aided design/Computer-aided manufacture) restorations are becoming increasingly popular in esthetic dentistry. Preparation design is influenced by the selected restorative material, the fabrication method, and the ability to bond the restoration. For long-lasting CAD/CAM inlay/onlay restoration, clinicians should understand the basic knowledge of CAD/CAM restoration's cavity design to obtain the fracture resistance and proper fitting margin. This article gives an overview of preparation guidelines for CAD/CAM inlay/onlay restorations.

Odometry using wheel encoder is a common relative positioning technique for wheeled mobile robots. The major drawback of odometry is that the kinematic modeling errors are accumulated when the travel distance increases. Therefore, accurate calibration of odometry is required. In several related works, various schemes for odometry calibration are proposed. However, design guidelines of test tracks for odometry calibration were not considered. More accurate odometry calibration results can be achieved by using appropriate test track because the position and orientation errors after the test are affected by the test track. In this paper, we propose the design guidelines of test tracks for odometry calibration schemes using experimental heading errors. Numerical simulations and experiments clearly demonstrate that the proposed design guidelines result in more accurate calibration results.

Today the Seoul metro has become the most important public transportation since opening in 1974. However, planning and design of stations, transfer systems and facilities are discorded by different companies and subway lines. Therefore, there is lack of objective design guidelines to secure legibility and safety in subway space. In this context, we aim to investigate the objective design and planing guidelines in terms of people's cognition and space use pattern. Space syntax method which enables scientific analysis is utilized to examine spatial layout considering passenger's spatial behavior. The research resulted in providing objective design and planning standards.

Since the computer technology has been drastically developed and broadly employed for the design of human machine system, human system interface was somehow digitalized. Actually the operator's working environment employing the digital devices are not be fully digitalized due to its technical constraints so that it has been changed to the hybrid environment which has a combination of digital and analog elements. The hybrid environments need to study its characteristics and the guidelines for the proper design and evaluation purpose. This paper describes the human factor design elements of the console operated under hybrid environment through studying the characteristics of digital and analog environment based on the related human factor guidelines and literatures. The result of this paper implies the contribution to the evaluation of the generic human working environment which digital and analog elements are jointly used.

Since Seoul city supplied 'Sangsang Children's Playground', domestic playgrounds are changing from formal facilities to creative play and learning space recently. From eco-friendly safe playground model development project, eco-friendly playground planning and its actual cases have been occasionally introduced. However, we could not know how well most playgrounds reflect eco-friendly features and whether they are eco-friendly or not because the definition about the concept of eco-friendly playground is inadequate and there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground. Therefore, the development of guidelines for the construction of eco-friendly playground is required and evaluation guidelines for them should be made for the active dissemination of the actual eco-friendly playground and the proper construction of the eco-friendly playground. In this study, we defined the concept of eco-friendly outdoor playground and presented the types and characteristics of the playground based on the concept and suggested basic plan guidelines based on the existing requirements for becoming eco-friendly playground. For this purpose, we checked the plan's common points in the existing playground configuration requirements, installation standards, regulations, and safety standards, and offered the planning elements and guidelines through the analysis of outdoor space evaluation standard in eco-friendly safe playground guidelines and eco-friendly building certification system.

The purpose of this study is to design and build fake news discrimination systems and methods using fact-checking guidelines. In other words, the main content of this study is the system for identifying fake news using Artificial Intelligence -based Fact-checking guidelines. Specifically planned guidelines are needed to determine fake news that is prevalent these days, and the purpose of these guidelines is fact-checking. Identifying fake news immediately after seeing a huge amount of news is inefficient in handling and ineffective in handling. For this reason, we would like to design a fake news identification system using the fact-checking guidelines to create guidelines based on pattern analysis against fake news and real news data. The model will monitor the fact-checking guideline model modeled to determine the Fact-checking target within the news article and news articles shared on social networking service sites. Through this, the model is reflected in the fact-checking guideline model by analyzing news monitoring devices that select suspicious news articles based on their user responses. The core of this research model is a fake news identification device that determines the authenticity of this suspected news article. So, we propose news article identification methods with fact-checking guideline on Artificial Intelligence & Bigdata. This study will help news subscribers determine news that is unclear in its authenticity.
