일반적으로 현재 많이 사용하는 장기 투영 시스템은 MRI와 CT이다. MRI와 CT는 전자기장을 이용하여 인체를 절개하지 않고 내부 장기를 의사가 볼 수 있도록 한다. 하지만 문제점은 단면적으로 영상을 보여주기 때문에 의사들이 내부 장기를 입체적으로 관찰하기 어려운 문제가 있다. 이 논문에서는 증강현실의 기술을 이용하여 사람의 내부 장기를 현실에 투영 할 수 있는 시스템을 개발한다. 개발한 시스템은 홀로렌즈를 이용하여 환자의 신체위로 내부 장기를 입체 영상으로 보여주며 핸드 모션을 이용하여 내부 장기를 이동시켜 상세하게 관찰이 가능하게 한다.

본 논문에서는 Zernike 모멘트를 이용한 새로운 얼굴 검출 기법을 제안한다. 입력 영상을 가변 크기의 영역으로 탐색하면서 Zernike 모멘트를 계산하여 신경망에 의해 얼굴과 비얼굴 영역으로 분류하여 얼굴을 검출한다. 직교 모멘트의 재구성 능력으로 인해, 분류기의 입력 특정은 화소의 수에 비해 감소될 수 있다. 또한, Zernike 모멘트의 크기는 회전에 불변한 특정을 가지므로, 회전된 얼굴 영역을 검출할 수 있다. Yale 데이터베이스의 영상에 대해 적용한 결과, 회전되지 않은 영상에서는 밝기값 정보를 사용하는 기법보다 약간 낮은 성능을 보였지만, 회전된 영상에 대해서는 월등히 높은 성능을 보였다. 국부 조명에 대한 추가적인 보상과 특징이 사용된다면, 강건한 얼굴 인식을 위한 전처리 과정의 핵심 기술로 사용할 수 있을 것이다.

본 논문은 일반적으로 많은 특징들을 갖고 있는 패턴 분류 문제인 감정 인식을 위한 새로운 특징 선택 방법을 제안한다. '특징 선택'은 패턴 인식 성능의 향상에 기여하고 '차원의 저주'문제에도 좋은 해결책으로 많이 사용되는 방법이다. 그래서, 본 논문에서는 강화학습의 개념을 사용한 상호 작용에 의한 특징 선택 방법인 IFS(Interactiv Feature Selection)를 고안하였고 이 알고리즘을 사용하여 선택된 특징들을 감정 인식 시스템에 적용하여 성능이 향상됨을 확인하였다. 또한 기존의 특징 선택 방법과의 비교를 통하여 본 알고리즘의 우수성을 확인하였다.

This paper deals with figurative meanings of Haewon-sangsaeng. It is an investigation which is both semantic and diachronic. In the first part, important implications of sangsaeng (or xiangsheng in Chinese) in the context of correlative cosmology are extensively explored. Among others, saeng (in Chinese sheng) as a powerful metaphor and its related Chinese compounds are broadly discussed. In the second part, the evolution of ideas of yuan (or won in Korean) in Chinese history is explicated. Above all, in the traditional Chinese cultural milieu, wrongful treatments which make victims feel themselves aggrieved are socio-politically orientated. The Scripture on Great Peace (Taiping Jing) is used as reference point to elucidate the essential points of yuan and its knots. However, the advent of Buddhism in East Asia adds a new dimension to the understanding of yuan (won). Accumulated yuan as karmic bond thus gives a new identity of yuan as predetermined animosity. Widely recognized idioms like "adverse relatives and karmic debtors" and indigenous Chinese Buddhist rituals like Repentance Ritual of the Emperor Liang bear witness to this transformation of the meaning of yuan in East Asia. The fruitful yet correlated meanings of yuan also make the endeavor of untying yuan deeply significant and important to human society. Haewon-sangsaeng, as a religio-ethical ideal, brings out an amicable and harmonious relationship among myriad beings in the cosmos.

Borescopes facilitate the inspection of areas inside machines and systems that are not directly accessible for visual inspection. They offer real-time, up-close access to confined and hard-to-access spaces without having to dismantle or destructure the object under inspection. Borescopes are ideal instruments for routine maintenance, quality inspection and monitoring of systems and structures. The main application being fault or defect detection, it is useful to have measuring capability to quantify object dimensions in a target area. High-end borescopes use multi-optic solutions to provide measurement information of viewed objects. Multi-optic solutions can provide accurate measurements at the expense of structural complexity and cost increase. Measuring functionality is often unavailable in low-end, single camera borescopes. In this paper, a single camera measurement solution that enables the size estimation of viewed objects is proposed. The proposed solution computes and overlays a scaled grid of known spacing value over the screen view, enabling the human inspector to estimate the size of the objects in view. The proposed method provides a simple means of measurement that is applicable to low-end borescopes with no built-in measurement capability.

A CAD program has recently been introduced that can be directly developed into a three-dimensional human body shape and made into a pattern. It is possible to fabricate a bra that reflects the volume and surface area of the breast; however, it still needs to be verified. This study investigates the average size and shape of 20 big-breasted women and designs a brassiere pattern for women with large breasts using a 3D Flattening function of OptiTex PDS v15.6. In addition, the study verifies the reliability of the proposed method compared to a conventional brassiere pattern. The study results are as follows. First, the three dimensional measurement values were smaller than the direct measurement dimensions when the three dimension measurement dimensions of the subjects were compared with the direct measurement dimensions, the replica measurement dimensions and the three dimensional measurement dimensions. Second, the 3D flattening pattern reflects the actual shape, length, and area of the actual breast when comparing a brassiere pattern using a 3D shape and pattern reflecting the direct measurement.

The purpose of this study is to analyze the body type characteristics of tall adult men aged 20 to 69 years to present base material on body dimensions for men's clothing companies. The research method comprised statistical analysis of 3D measurements after selecting items from the 8th Korean human body size survey related to the torso body types of 495 adult men who were at least 178cm tall. As a result, six factors were extracted, and the total explanatory variable of the entire factor was shown to be 80.499%. As a result of cluster analysis using this as an independent variable, three types were derived: Type 1, "a normal body type with an oval cross-sectional shape" (37.6%), with a larger vertical size and an oval chest cross-sectional shape compared to other types; Type 2: a "cylindrical thick body shape" (31.1%), which is the first stage of BMI obesity, with narrow shoulders and a cylindrical shape with a round cross-section; Type 3, "a body shape with broad shoulders and developed chest parts" (31.3%), with a horizontal size similar to Type 2 above the waist, but similar to Type 1 below. The results of this study are expected to be used as a basis for a clothing dimension system and clothing development for tall men reflecting the characteristics of the torso.

This paper presents a conceptual approach to Smart Tourism Design based on semiotic affordances theory. This conceptual approach repositions smart tourism from a techno-centric perspective that frames a seamless connection between the device and its software, to a more human-centric perspective that favors the user's needs, desires as perceived through the senses. An updated Smart Tourism Design emphasizes the aesthetic dimension of smart tourism that presents the objects of the travel experience as destination specific rather than universal, through representations as digital artifacts. This theory is based on an empirical and objective understanding of representations and how they can be identified as useful in the digital augmentation of travel experiences. Using Peirce's sign systems and Gibson's theory of affordances, smart tourism can transcend a prefabricated device-oriented experience to a closer dynamic and direct interaction between the user and the travel destination. Researchers and developers can use semiotics as a structural approach to recognizing objects as sign-types, and they can use affordances to better identify the immediacy of digital artifacts and purpose-driven by users' spontaneous and immediate motives.
