These days, VR contents are created in three ways: CG based method, game engine based method, and live action shooting method. The most universal method is live action shooting. So far, most live actions are shot with action cams. Therefore, this method is different from professional image production method for movies and TV dramas. This study tries to point out the difference between professional image production method and action cam based shooting method, and proposes an alternative. The proposed method is log shooting based HDR filming and editing. As the result of test shooting and editing, the proposed method was able to obtain more color information than conventional action cam based shooting method and thereby to implement high-definition images which are hard in an action cam.

This paper presents the results of a laboratory investigation on construction method of geogrid encased stone column (GESC). In order to analyze effects of load carrying capacity and geogrid deformation characteristics of GESC, a series of medium scale unconfined compression tests with different overlay methods and reduced model tests were performed. The test results show that the method of overlap provides a simple and effective method of encasement construction. It is also found that geogrid encasement construction using method of overlap has important factor which can be applied to field tests. The geogrid encasement method related to effect of reinforcement is presented by laboratory test results.

The purpose of this study is to investigate the production method of posterior bridges pontic ridge lap type which prevents the infection in bridge pontic base and is able to cleanse itself, in the process of producing final prothesis that maintains healthy mucous membrane of oral cavity and interproximal papilla, minimizing diastema, is aesthetic and has no effect on pronunciation. New technology is applied to make optimal pontic base which prevent inflammation and clean itself and its products were clinically evaluated in 10 places of dental clinics in busan and gyeongnam. The making of posterior 3 unit bridge pontic base, it was presented as the new technology of forming ridge lab type and to carry out clinical validation, existing conventional method and the new technology were compared. Pontic base made with the existing conventional method cause infection and other periodontal disease by 96% but the pontic base made with the new technology cause infection and other periodontal disease by 3%. Remains of food cause infection and other periodontal disease 100% by the existing conventional method and 91% by the new technology, showing a distinct difference. However, after a gargle, the new technology had low 13%. Additionally, the pontic base made with the existing conventional method showed 71% of chance, the new technology method showed 8% of chance in terms of self-cleansing.

In this paper, we proposed the fabrication methodology of orthotic device using 3D Computer-Aided Design programme and 3D printing technology based on images acquired from 3D scanner. We set the process and methodology of its fabrication method and confirmed whether it is available for clinical by fabricating four kinds of orthotic device for a patient with cerebral palsy. 3D printing technology method was indicated quantitatively and qualitatively about duration, tensile strength stronger comparing with conventional method, and we could propose that the 3D printing technology for the orthosis could be the proper method to mediate and compensate with reported problems related to orthosis.

For the activation and wide distribution of User Created Contents (UCC) sites have diversified user-created possibilities. Among these contents, User Created Game (UCG) sites are places where users can create and share their game contents with others. The method of UCG development can be classified into two categories according to the uses' level of professionalism. First, the method of using the authoring tools is suggested for those unfamiliar with the development or creation of contents. Although the authoring tool is easy to use, there are many functional limitations. Second, development using program languages is suggested for trained advanced users but has the limitation of a prolonged development period. This paper proposes a new method, generating the script which will expand the current functional limitations entailed behind the authoring tools used by first time and less trained users. In order to verify the proposed method in a real UCG development environment, a framework encompassing GUI, script generating function and program source generating function were constructed.

"The Plan for the Development of the National Geographic Information System" designates the following six major thematic maps as the main subject of digital mapping project: topographic-cadastral maps; administrative boundary maps; land use maps; road network maps; national land zoning maps; and urban planning maps. Carrying out the digital mapping project requires standards and guidelines for digitizing process. However, there is neither standards nor guidelines with regard to thematic map production. This study describes the steps involved in producing thematic maps and provides the best procedural alternative for the production of thematic maps. Based on procedural alternative suggested by this study, actual digital maps have been experimentally produced for the selected area, Anyang-Si Dongan-Gu. The results of this experimental work have been utilized to government for not only making the guidelines but also initiating plans for the development of thematic map production.roduction.

TRL 오차 수정방법은 기판 위에 제작된 고주파 소자를 측정할 때 많이 사용되는 방법이지만 오차수정을 위해 제작된 표준 전송선 패턴의 특성 임피던스를 알아야만 보다 정확하게 측정 오차를 수정할 수 있다. 기존의 방법에서는 저항을 종단 처리한 표준 패턴을 추가로 이용하여 전송선의 단위 길이 당 커패시턴스를 계산하고 주파수에 대해 fitting하는 방법으로 표준 전송선의 특성 임피던스를 계산하고 있으나 제작상의 부정확성에 의해 추출된 특성임피던스가 영향을 받고 있음을 확인하였다. 본 연구에서 제안하는 새로운 방법을 이용하면 fitting하는 과정 없이 각각의 측정주파수에서 직접 특성 임피던스 추출이 가능할 뿐 아니라 제작상의 부정확성을 측정결과로부터 처리할 수 있으며 검증 결과 기존 방법 보다 정확한 특성 임피던스를 추출할 수 있었다.

In this paper, the lumped element model parameter estimation method and its implemented estimation software for fabricated floating mass transducers of IMEHDs have been presented so that the estimated parameter values could be compared with the designed ones and applied to predict the output performance when the transducers were implanted into human ears. The presented method is based on the sequential quadratic programming (SQP) for estimating parameters in the transducer's lumped model and has been implemented by the use of LabVIEW graphical language. Using the implemented estimation software, the accuracy of parameter estimation has been verified and our implemented estimation method has been evaluated by the comparison of the estimated transducer parameter values with the designed ones for a practically fabricated floating mass transducer for IMEHDs.
