This study proposes a way to validate BIM data quality in BIM applications. Solibri model checker is adopted as a module development platform, which is based on Java programming language. The platform makes application developers implement BIM model checker for their own purpose. This study has developed a BIM validation module for circulation analysis of building design. The validation module enables end-users to automatically detect data corrupted or not defined. In case studies, the module found that an IFC file generated from a BIM software has wrong relation information between a space and boundary elements. A building model should satisfy modeling requirements and then domain users can get analysis results. The BIM data validation module needs to be developed in each BIM application domain.

This paper describes the economic evaluation of battery energy storage system(BESS) for the domestic application. Application target is decided on conventional combined cycle of domestic and we analyzed economics that compared conventional combined cycle with power generation cost in development and the commercialized in case that establish it on utility and customer, urban and rural. The result shows that about the same conventional combined cycle of Anyang, Bundang and Pyungtak but more economical than seoincheon conventional combined cycle. And, in case of capacity enlargment and using the maintenance free battery more economical than conventional system.

Land suitability classification(LSC) is an appraisal and grouping(or the process of appraisal anti grouping) of specific tracts(of land) in terms of their relative land suitability for a definEd use, and is one of the land use planning techniques. This paper reviews the selected studies on LSC whose purposes are to especially contribute land use planning in case of Japan, So, this study examines the LSC's application to Korea based on Japanes LSC studies with a view to development of the methods on LSC for rational land use planning in our rural area. The result resolves itself into Table 2. However, it is undesirable to borrow from Japanes LSC studies like that, because of the difference of administrative,geographical,traditional,social and economical conditions. Therefore, it is necessary that the many case studies and examinations should be carried out in order to develop the methods on LSC suitable to Korean actual circumstances.

This global case study pursues diversification and intensification for an application system of the national wind atlas which has been developed to support national strategy building and promotion of wind energy dissemination. We chose nine counties' national wind atlas and compared their map area, extraction height, temporal and spatial resolutions, download services, etc. to derive a best practice for the Korea wind atlas application system. Therefore, the web service content is designed to offer high-resolution height information of which covers wind turbine rotor sweeping area and time-series dataset which can be downloaded for further analysis by users. It is anticipated that the system and web service would contribute greatly to wind energy policy making, business and research sectors.

Smart Grid는 전기망과 정보통신망이 융합된 형태로 발전 송전 배전의 전 과정에 대한 통제가 가능하고, 결과적으로 에너지 사용의 효율성을 높이고자 하는 것이 지능형 전기망이다. 정보통신망을 이용하기 때문에 기존의 다양한 사이버 보안위협으로부터 그대로 노출되어 있으며, 전기망에서의 취약점도 함께 가지고 있다. 본 논문에서는 우리나라보다 먼저 Smart Grid를 도입한 나라의 Smart Grid 공격 사례와 예상 공격에 대한 취약점을 분석하고, 분석된 취약점에 대한 Smart Grid 보안 대책을 마련한다. 본 연구를 통해 Smart Grid에 대한 보안성 강화와 사회안정성 향상에 기여하게 될 것이다.

A 2-month-old, 50 kg male Korean native calf was referred with bilateral mandibular fractures. The bilateral mandible was hanging loose, with inability to use the jaw, indicated by excessive salivation. Radiography revealed a long oblique fracture in the right mandible, and a short oblique fracture in the left mandible. Computerized Tomography, a different form of radiography, revealed the fracture in the left mandible to be a comminuted fracture. In order to stabilize the bilateral mandible fractures, a combination of bone plate and wiring was applied; in addition, resin was applied to enhance stabilization of the mandible. Six weeks after surgery, the calf was able to masticate and ruminate well. In this case, application of the plate and wiring with resin to bilateral mandibular fractures presented a successful functional recovery. Accordingly, the combination of bone plate and wiring with resin can be an effective technique for treating mandibular fractures.

In this study, there are many difficulties in defining and judging creative people because there is no systematic analysis method using accurate standards or numerical values. Analyze and judge whether In the previous study, A study on the application of rule success cases through machine learning algorithm extraction, a case study was conducted to help verify or confirm the psychological personality test and aptitude test. We proposed a solution to a research problem in psychology using machine learning algorithms, Data Mining's Cross Industry Standard Process for Data Mining, and CRISP-DM, which were used in previous studies. After that, this study proposes a solution that helps to judge creative people by applying the feature selection algorithm. In this study, the accuracy was found by using seven feature selection algorithms, and by selecting the feature group classified by the feature selection algorithms, and the result of deriving the classification result with the highest feature obtained through the support vector machine algorithm was obtained.

Anterior open bite and transverse discrepancy are often accompanied by hyperdivergent skeletal patterns. In addition, degenerative joint disorders and vertical maxillary excess contribute to an unfavorable convex facial profile with a retruded chin. Correction of this complex three-dimensional problem with orthodontic treatment alone is considered challenging owing to anatomical limitations. Moreover, a history of orthodontic treatment with premolar extraction makes retreatment difficult. This case report illustrates the application of a maxillary tissue bone-borne expander and biocreative reverse curve system in a 23-year-old female patient with a severe anterior open bite and transverse discrepancy who underwent orthodontic treatment with four premolar extractions. By setting the treatment target under precise diagnosis and using appropriate appliances, a satisfactory treatment result could be achieved without orthognathic surgery.

An application case of systems engineering (SE) processes for the small unmanned aerial vehicle (UAV) development project, which was funded by the Korean government during June 2017 ~ August 2020, is briefly presented in this paper. From the beginning to the end of the project, SE processes had been applied and managed by simple and intuitive aspects for the small/medium business companies joined with insufficient experiences of SE. And the specific considerations of the processes were focused to the missions of disaster and public safety purposes required from the government, such as identification, patrol, fire, rescue, etc. As a result, the project applied by the tailored SE processes had been rated of a good and higher accomplishment on the final evaluation, and then the related several programs were prepared successively for the other opportunities.
