This research is an experimental study on BIPV Power performance of See-through a-si and Light-through applying external curtain wall. In case of See-through a-si Photovoltaic, appropriateness of facade applying standard($950\;{\times}\;980mm$) large($950\;{\times}\;1960mm$)area photovoltaic was examined. Transparent performance was also investigated through Power simulation according to angles and seasons of See-through a-si and Light-through Photovoltaic so that Power output was surveyed with using designed and manufactured Mock-up. When comparing See-through a-si to Light-through Photovoltaic for simulation Power output on angles based on full south aspect, which the result was that See-through a-si Power output according to Light-through Power output was the highest of 65.5% when applying a 90 degree angle. Monthly accumulated average Power output during winter seasons (December, January and February) applying a vertical plane on full south aspect was analyzed, which results in 66.37W/h of See-through a-si and 139.1 W/h of Light-through. See-through a-si Power output showed 47.7% in comparison with Light-through transparent. Also monthly, hourly average Power efficiency according to solar radiation during winter seasons (December, January and February) was that 4.7% of See-Through a-si and 9.8% of Light-through.

Dresses reflecting human aesthetic consciousness are used as a way of expressing the inner desire of human beings. The desire to attract the opposite sex through sexual appeal among the human inner desires is the one innate characteristic that all human beings have. We may say that the $See-through$ look emphasizes a sense of softness and femininity by exposing the skin and expresses bodily beauty by way of using see-through cloth. It is a fashion style that can express sexual appeal and eroticism of female most effectively. In this study, after observing the motivation of dress wearing and $See-through$ look in the perspective of bodily concept and eroticism, colors of $See-through$ look shown in the $Pret-a-Porter$ Paris S/S collection from 2006 and 2007, a fashion style expressing eroticism was newly re-analyzed as romanticism and glam look particularly in 60, 80s compared with other times were re-created and evaluated. As a result of analyzing colors of the $See-through$ look, Yellow Red(close to skin color) was revealed to be the highest( 31.3%), followed by Red(9%), Purple Blue(7.2%), Yellow(7.2%), Purple(5.4%), respectively and in terms of color tone, pale and gray tones that have a sense of femininity and softness was revealed to the highest(20%) followed by ltg(11%) and dkg(9%). We may find the meaning of this study in analyzing colors of the $See-through$ look, and the typical look of eroticism, which has never been tried before. It is required to identify chronological color features of the $See-through$ look and the diversified characteristics of skin colors expressed in them to prepare useful data by which a sense of the $See-through$ look can be utilized for color coordination through the relationship between skin tone and dress by pursuing a more detailed method based on the result of this study.

In Korea, the military has been conducting counseling forthe preemptive detection of psychologically unstable soldiers to prevent unexpected accidents and to help them adapt to military life. However, several soldiers feel anxious about face-to-face counseling with military officers and they have difficulty expressing themselves. Video See-Through HMD is a state-of-the-art mixed reality device that converts the user's real view into a digital view, which leads users to feel the actual situation as the virtual. To validate its usefulness as a new psychological counseling aid, we investigated 11 army soldiers who are under the counseling program in barracks. During the counseling conversation, participants were asked to wear or take off the Video See-Through HMD repeatedly. All conversations were recorded for behavioral observation. As a result, 80% of the soldiers showed a relatively stable state of mind when wearing the Video See-Through HMD, which leads them to be innocent and frank about their concerns. This method could improve the effectiveness of counseling to prevent unexpected accidents caused by unnoticeable psychological instabilities of the clients.

본 논문에서는 Video see-through HMD 에 기반 하여 증강 현실을 위한 손 인터페이스를 제안한다. 착용형 컴퓨터의 입력 장치로써 Video see-through HMD 에 부착된 USB 카메라로부터 영상을 입력 받은 후, HSV 컬러 공간에서 탐색 윈도우 안의 개체를 이중 임계 값을 이용해 손과 팔이 포함된 객체로 분리한다. 그 다음 거리 변형 행렬을 이용하여 손과 팔을 분리하고, 볼록 다각형 외각점 추출을 통해 손 끝의 좌표를 검출한다. 이를 기반으로 한 어플리케이션 "AR-Memo"은 현실세계에서 손끝에 가상의 펜을 증강하여 메모를 하고 이동중에 손바닥을 통해 메모를 볼 수 있다. 증강 현실 기반 손 인터페이스를 사용함으로써 사용자는 이동중에도 직관적으로 입력을 할 수 있다. 또한 어떠한 물리적인 장치나 마커를 손에 부착하지 않기 때문에 자연스러운 인터페이스이다. 본 시스템은 착용형 컴퓨터와 결합되어 사용자에게 편리한 인터페이스를 제공할 수 있을 것으로 기대된다.

The transmittance of the three dimensional (3D) transparent display is an important factor and can be enhanced by adding a see-through area to the displayed 3D image in order to transmit an ambient light with maximum transparency. However, there is a side effect that the perceived 3D resolution can be degraded due to the see-through area. In this paper, we propose an advanced method to resolve the above trade-off relation between the transparency and the 3D resolution by using an active parallax barrier (PB) with a see-through area. The experimental results are also presented to prove the proposed principle.

Transparent Photovoltaic (PV) modules have recently been in the spotlight because they can be applied to buildings and vehicles. However, crystalline silicon (c-Si) solar modules, which account for about 90% of the PV module market, have the disadvantage of applying transparent PV modules due to their unique opacity. Recently, a see-through type PV module using a crystalline silicon solar strap has been developed. However, there is a problem due to a decrease in aesthetics due to the metal ribbon in the center of the see-through type PV module and difficulty bonding the metal ribbon due to the low voltage output of the strap. In this study, to solve this problem, we developed a fabrication process of series connected c-Si solar strap cells using the c-Si solar cells. We succeeded in fabricating a series connected strap with a width of 2-10 mm, and we plan to manufacture an aesthetic see-through type c-Si PV module.

Dynamic visual acuity is used as an important factor to measure athletic performance in sports field. A study on visual acuity testing system using non-see head mounted display (NST-HMD) was conducted recently. However, the NST-HMD has a problem that the sense of space felt by the subject differs from the actual environment. This is because the view is blocked so that it is only implemented in a virtual space. This paper proposes a dynamic visual acuity testing system using optical see through head mounted display (OST-HMD). To do this, OST-HMD and NST-HMD comparative tests were conducted using existing K-D (King-Devick) charts. Experiments were performed on 30 subjects and their visual acuity was measured and analyzed by parametric statistics and one-sample T-test. The results of the study demonstrate the effectiveness of the proposed OST-HMD. This study is expected to use the visual inspection and training equipment of OST-HMD.

The purpose of this study is to consider the formative characteristics of dance sports from such points of view as shapes, colors, material and decorations, and to examine artistic characteristics that are expressed through those elements. As a result, this study shows five artistic characteristics as follows; First, rhythmic characteristic is expressed with repeat of lines that is formed by pleats, shirring or gather, with duplication of ruffle's wave, with gradation of colors, with Moire-effect that is generated with overlap of see-through material, with glossy material that reflects lights to a great extent, with fringe. Second, bodily characteristic emphasizes the beauty of human bodies through direct or indirect body exposure by way of cut-and-open, see-throughness or close adhesion. Third, decorative characteristic is shown with beads, fringe, ruffle, embroidery, shirring, binding, or feather. Fourth, the beauty of female body is manifested to express eroticism, which is culminated by body exposure, body consciousness, use of illuminating or see-through material or colorful trimming. Finally, elegant characteristic is revealed through feminity, sophistication, and harmony that are expressed with black and white colors, see-through material, or bead trimmings.
