In this study, the temperature control device was designed for the study in order to detect the output in frequency of temperature, and the study confirmed accurate temperature values treated systemically by using expanded A/D converting Technology. The control technology of functional sensor included the output error Detection. For the future study, it is necessary to implement a control device by building multiple circuits integrally with different types of sensors such as a automatically and intelligent notification function sensors.

최근 널리 사용되는 모든 비파괴검사 기술 중 적외선열화상 카메라는 점차 적용 범위를 확대하고 있다. 초음파적외선 열화상은 절대온도 0 K 이상의 모든 물체가 방출하는 적외선 에너지를 검출하여 검사자가 볼 수 있는 화상으로 이미지를 만들어 검사하는 기술에 초음파를 접목하여 결함 부위만을 검출하는 방법으로 비접촉으로 넓은 범위를 빠른 시간에 검사할 수 있는 장점이 있는 기술이다. 본 연구에서는 고유주파수를 변화할 수 있는 터패놀-D 소재의 가변초음파 가진검사 방법을 이용하여 결함 검출의 적용가능성을 연구하였다.

This paper presents an attempt to develop a visual programming language-based 3D virtual reality authoring tool intended to compose virtual interior space. The rapid development of digital technology and the wide spread of the Intenet have expanded the different uses of virtual reality in a number of applications ranging from interior design to building maintenance. In particular, the construction of cyber spaces based on existing interior spaces is becoming increasingly important. Current research, however, remains at the level of converting 3D models into virtual reality models, despite practitioners' needs for structural space models. Moreover, commercial tools to build virtual reality space have the disadvantage of targeting people who have professional knowledge of computer programs and computer graphics. Accordingly, the 3D virtual reality authoring tool developed in this research - called the VESL system - enables virtual and structural space to be easily composed using intuitive and interactive visual interfaces, which are based on visual programming techniques. The VESL system also provides an XML based semantic description of interior space, to be used to describe interior space information. We anticipate that the virtual reality spaces composed by this system will be of considerable use in the fields of architecture and interior design. Further research issues identified at the end of the research include developing a converter/filter for transforming Internet virtual reality standard language, or VRML, and evaluating the application of the system for practical use.

This study aims to present the direction of research for rational clothing design and production and improve the productivity of the fashion industry by analyzing the most recent 11 years (from 2010 to 2021) with regard to the clothing construction field. Analyzing the research trends in the field of clothing construction, which is deeply related to clothing production, will suggest the direction of research for clothing design and production. To analyze the current status of research in the field of clothing construction, research trends were analyzed, focusing on 525 research journal articles from six Korean clothing-related journals with terms related to torso and upper and lower limbs. The analysis results of this study are as follows. First, the rapid development of IT technology requires changes and innovations in all processes of clothing construction, including body shape analysis and pattern design. Therefore, it is believed that both body shape and pattern research should be continuously conducted to produce clothes with an excellent silhouette and fit depending on the body shape through studies, such as developing 3D patterns and converting 3D body figures into 2D patterns, among others. Second, since body shape studies are concentrated on young, middle-aged, and the elderly, it is believed that various body shape studies should be conducted on infants and elementary, middle, and high school students who have significant changes in body shape due to changes in the living environment. Third, if the content of pattern research is expanded to various items and is widely conducted, it will contribute to the production of clothing that has an excellent fit. Fourth, at a time when aging in society is accelerating, it is believed that research on patterns and clothing systems that can increase the fit of clothing by analyzing the body types of elderly male and female consumers should be actively conducted. Because the analysis was conducted only among six Korean academic journals, there is a limitation in the expanded interpretation of the results derived from this study.

고령화 시대로 변화해 가면서 재활 복지 산업, 스포츠 산업 시장이 빠르게 성장하고 있다. 특히, 근전도, 뇌전도, 안전도등 생체신호를 이용하여 휠체어 등 복지기기, 의수 및 의족을 제어할 수 있는 재활기기 및 일상의 전자기기 등을 제어할 수 생체 인터페이스 분야는 새로운 미래 신기술영역이며, 또한 사회적 약자인 장애인, 노약자, 재활환자에게 많은 도움을 줄 수 있을 뿐만 아니라 일반인에게도 다양한 응용분야에서 활용될 것이다. 상용화된 생체신호계측 장비 및 인터페이스의 경우 부피가 크고 복잡하며, 고가 제품으로 실생활에 이용하기에는 많은 제약을 갖고 있다. 본 논문에서는 휴대가 가능한 형태의 소형 근전도 신호계측 장치를 구현하였으며, 무선 전송이 가능한 형태의 인터페이스 시스템을 통하여 근전도 신호를 통한 하드웨어 장치 제어가 가능한 제어모듈 개발에 관한 연구를 수행하였다. 손목의 움직임을 통해 발생된 근전도 신호를 입력받아 불필요한 잡음을 제거하고, 신호를 증폭하는 휴대형 하드웨어 모듈을 설계 하였다. 획득된 근전도 신호를 디지털 신호로 변환과 함께 디지털 필터링을 위해 TI사의 TMS320F2808 DSP칩을 사용하여 구현하였다. 또한 획득된 근전도 신호로부터 주성분 분석 기법을 이용하여 상, 하, 좌, 우의 4 동작신호로 분류하였으며 분류된 데이터는 PC 터미널로 무선 전송하여 표시하도록 하였다. 최종적으로 4가지 동작에 대해 85%의 인식률을 얻었으며, 지금보다 높은 인식률을 얻게 된다면 근전도를 이용한 손목동작을 통하여 다양한 하드웨어 시스템을 제어하는 제어신호로 활용이 가능하리라 본다.
