We propose a bar-type three-dimensional holographic head mounted display using two optical elements. Conventional stereoscopic displays may suffer from eye fatigue because the images presented to each are two-dimensional ones, which causes mismatch between accommodation and vergence responses of eye. The proposed delivers eye, removing problem. In this paper, we discuss configuration waveguide analyze aberration caused by non-symmetric diffraction angle elements used as input output...

Fully analytic mesh-based computer generated hologram enables efficient and precise representation of three-dimensional scene. Conventional method assigns uniform amplitude inside individual mesh, resulting in reconstruction the scene flat shading. In this paper, we report an extension conventional to achieve continuous shading where each mesh is continuously varying. The proposed shading, while maintaining fully framework without any sacrifice precision. can also be extended enable fast...

In the retina, a number of degenerative diseases, including glaucoma, diabetic retinopathy, and age-related macular degeneration, may occur as result aging. Oxidative damage is believed to contribute pathogenesis aging well retinal disease. Although physiological exercise has been shown reduce oxidative stress in rats mice, it not known whether similar effect tissues. The aim this study was evaluate naturally-aged mice. addition, we evaluated effects aerobic training on by...

We propose a method to capture light ray field of three-dimensional scene using focal plane sweeping. Multiple images are captured usual camera at different distances, spanning the scene. The then back-projected four-dimensional spatio-angular space obtain field. obtained can be visualized either digital processing or optical reconstruction various display techniques including integral imaging, layered display, and holography.

This study investigated the impacts of two different urban development strategies (infill and suburban new town development) on changes in land surface temperature (LST) Seoul metropolitan area. One large-scale infill site three towns developed between 2004 2014 were selected as case areas. The authors retrieved LSTs normalized difference vegetation index (NDVI) from remote sensing images for both years, combined them with parcel-based use information. descriptive statistical results showed...

Mesh-based computer generated hologram enables realistic and efficient representation of three-dimensional scene. However, the dark line artifacts on boundary between neighboring meshes are frequently observed, degrading quality reconstruction. In this paper, we propose a simple technique to remove by matching phase meshes. The feasibility proposed method is confirmed numerical optical reconstruction hologram.

Secreted protein acidic and rich in cysteine (SPARC) is associated with skeletal muscle atrophy. Here we examined possibility that resistance training could regulate SPARC expression atrophy an immobilized hindlimb model.Sprague-Dawley rats underwent ladder immobilization. Cross sectional area grip strength were measured. levels the plantaris soleus, serum after exercise immobilization then analyzed.Resistance decreased body weight (P < 0.001) increased quality 0.001). In plantaris, (31.82%)...

In the present study, we investigated effects of 8 weeks progressive resistance training on level skeletal muscle derived BDNF as well glucose intolerance in Zucker diabetic rats. Six week-old male fatty (ZDF) and lean control (ZLC) rats were randomly divided into 3 groups: sedentary ZLC (ZLC-Con), ZDF (ZDF-Con), exercised (ZDF-Ex). Progressive using a ladder tail weights was performed for (3 days/week). After training, substantial reduction body weight observed ZDF-Ex compared to ZDF-Con....

[Purpose] This study aimed to investigate the effects of leucine-enriched essential amino acid (LEAA) supplementation on muscle fatigue and level inflammatory cytokines in wheelchair basketball players after a game interval training. [Methods] Of ten recruited (aged 34.5±8.9 years; lean body mass 34.3±10.0 kg) who had spinal cord injury (SCI) undergone amputation, nine participated final test. These athletes received LEAA supplements (3 times 4.0 g/day) or placebo treatment double-blind,...

Recently, head mounted displays based on holographic optical elements have been reported. These can be implemented in a compact form factor but the image delivered to user's each eye is still two-dimensional, which causes accommodation-vergence mismatch. In this paper, we propose three-dimensional display images eye. The proposed configuration achieve by using elements, and solve mismatch presenting

Background In the present study, we determined effects of HX108-CS (mixed extract Schisandra chinensis and Chaenomeles sinensis) supplementation on lactate accumulation endurance capacity. Furthermore, examined CK (creatine kinase), LDH (lactate dehydrogenase) activity to determine whether affected markers skeletal muscle injury in vivo vitro. Methods Exercise capacity was measured by an exhaustive swimming test using ICR mice divided into four groups; one group received distilled water (DW)...

High-resolution (HR) 360° images offer great advantages wherever an omnidirectional view is necessary such as in autonomous robot systems and virtual reality (VR) applications. One or more adjacent views can be utilized to significantly improve the resolution of a target image. In this paper, we propose efficient reference-based image super-resolution (RefSR) technique exploit wide field (FoV) among cameras. Effective exploitation spatial correlation critical achieving high quality even...

한국정보화진흥원에서 개발한 한국형 성인 인터넷 중독 자가진단 척도인 K-척도는 4가지 요인의 20 문항으로 구성되어 있으며, 사용자의 설문응답값으로 중독을 진단한다. 기존의 연구는 대부분 중독의 원인을 찾으려는 시도였으며, 청소년 대상으로 수집된 표본을 가지고 그들의 중독진단이 수행되었다. 본 연구의 목적은 통계 기법의 주성분분석과 데이터마이닝 기법인 의사결정트리를 이용하여 K-척도의 사용자군 분류를 판정하는 주요인을 발견하는 것이다. 실험 결과로부터 K-척도를 구성하는 요인 중 내성 및 몰입 요인이 중독진단에 가장 큰 영향을 주는 요인임을 알 수 있었다. Korean adults' internet addiction diagnosis measure, K-scale developed by Korea National Information Society Agency (NIA), has composed of 4 categories including items. This scale...

Energy acquisition due to the increase of oil price is one most important issues and policy for countries. Various tankers have been built in world sent trade market. It necessary build port infrastructure facilities give them proper services such as mooring, packing, storing, transshipment, etc. However, domestic guidelines or standards design construction dolphin berth among these are out date do not meet recent trend tanker types. Therefore, it requires amendment on standards. In this...

Abstract Understanding the growth of tropical convective clouds (TCCs) is vital importance for early detection heavy rainfall. This study explores properties TCCs that can cause them to develop into with a high probability precipitation. Remotely sensed cloud properties, such as cloud-top temperature (CTT), optical thickness (COT), and effective radius (CER) measured by geostationary satellite are trained neural network. First, image segmentation algorithm identifies TCC objects different...
