        Information and communication technology(ICT) around the world in the 21st century presents a new vision of agriculture. Time, place, and the high-tech industry to overcome barriers to the fusion of the so-called “smart agriculture” is changing the landscape of agriculture. Precision Agriculture’s core container production for the mushroom cultivation temperature, humidity, irradiation, self-regulation, such as carbon dioxide, the optimal environment for mushroom cultivation was implemented. Auricularia auricula-judae, known as the Jew's ear, wood ear, jelly ear or by a number of other common names, is a species of edible Auriculariales fungus found worldwide. The fruiting body is distinguished by its noticeably ear-like shape and brown colouration. The fungus can be found throughout the year in temperate regions worldwide, where it grows upon both dead and living wood. We controlled different light source (Blue-Red-White combined LED, blue LED, red LED and fluorescent light) with different intensity of LED irradiation (1.5, 10.5 and 20.5 μmol/m2s for LEDs) to compare growth and development. Lights were treated with 12 hour on/ 12hour off cycle maintained in a controlled room with 19 ~ 21oC temperature, 85~95% humidity, and 1000ppm CO2 atmosphere concentration for 30 days. Growth and development differed from the LED color source and intensity of LED irradiation. Growth and development was most effective in 1.5 μmol/m2s irradiation for blue LED. All LED light sources showed less growth and development in highest intensity of irradiation, which indicates that higher than 20.5 μmol/m2s for LED is not effective. After harvesting fruit bodies, we measured their weight, length, width, thickness and chromaticity of fruit bodies. 1.5 μmol/m2s blue LED group was the best result of harvest with average individual weight (5.38g), length (65.37mm), width (56.87mm) and thickness (13.51mm) with fine chromaticity. This results show us that 1.5 μmol/m2s blue LED was the best effect on growth and development of Auricularia auricula-judae mushroom’s ICT system container type environment.

Hericium erinaceum (also called Lion's Mane Mushroom, Bearded Tooth Mushroom, or Bearded Tooth Fungus) is an edible mushroom and medicinal mushroom in the tooth fungus group. Native to North America, Europe and Asia it can be identified by its tendency to grow all the spines out from one group (rather than branches), long spines (greater than 1 cm length) and its appearance on hardwoods. About 40 days of incubation 1.5kg oak sawdust was used as the test medium bag. The humidity was maintained more than 85~95% and temperature was 18~20°C, and CO2 density was 500~1,000ppm. The days for primordium formation showed us 6~12 days. The amount of fruitbody production was 110~260g per bag. This technique to establish new community support program in conjunction with the international movement, domestic sales and exports are also planned.

        As well as all other branches of trade, so retail trade itself undergoes various changes and trends with regard to the development of information and communication technologies which affect not only traders themselves but also their customers. It is the retail store environment itself which is one of the decisive aspects of purchase because more than 70% of consumer decisions take place directly at the point of sale. It is the last place which can reverse the purchasing decision. A final customers´ decision is influenced not only by price, quality but also by in-store communication and visual aspects of each store. That is the reason for continuous gathering of feedback on the effectiveness and efficiency of these means of communication in real environment. Besides traditional research techniques there are situations which require the involvement of relatively new research methods. Thanks to the innovative interdisciplinary approach with the use of neuromarketing, it is possible to create effective marketing strategies and thus stimulate the customer attention and emotions. By these emotions, it is possible to achieve better motivation toward purchase and an increase in the number of sales and subsequent raise in income. The paper deals with a complex, interdisciplinary examination of the in-store communication impact on customer visual attention, emotions and related spatial behaviour of customers in grocery stores. Research integrates measurements of mobile eye camera (Eye tracker), mobile electroencephalograph (EEG), face reading technology (FA) and internal position system in real conditions of retail store. The purpose of this research is to recognise the attention, emotional response and spatial customer preferences by means of selected in-store communication tools. At the end of the paper we explain how the neuromarketing methods can be used for better understanding of consumer behaviour at the point of sale.

        To precisely assemble the fuel test rod, an orbital TIG welding system was designed and developed to accurately conduct orbital TIG welding for the nuclear fuel test rod. Using this system, a welding process needs to confirm the welding properties for orbital TIG welding. Therefore, preliminary weld tests were performed on the cladding tubes under various conditions, and the results show that the width and depth of HAZ of the cladding specimen welded using identical power during an orbital TIG welding cycle was continuously increased from a welded start-point to a welded end-point because of heat accumulation. The performance tests were conducted under the welding conditions considered through preliminary welding tests, and the properties of the specimens were conformed through surface and microstructure analyses.

        HFCs, PFCs 및 SF6 등으로 대표되는 불화가스는 반감기가 길고 지구온난화지수(GWP)가 높아서 그 발생량에 비해 지구온난화에 미치는 영향이 상대적으로 높다. 특히 반도체/LCD 제조공정에서 발생하는 폐 PFCs는 저농도로 분리농축공정의 경우 공정 특성 상 정압제어가 가능한 기술이어야 한다. 본 연구에서는 이를 고려한 분리·농축 시스템으로 분리막시스템과 혼성시스템(분리막+흡착)을 설계, 제작하여 비교연구를 수행하였다. 그 결과, 불화가스 농축도는 분리막시스템이 혼성시스템에 비해 높았으나, 회수율은 낮았으며 혼성시스템의 경우 대체적으로 농축도는 낮은 반면, 회수율은 높은 결과를 보였다.

        This research introduces the interactive fairy tale system based on BCI and Motion Sensing Technology for Children with ADHD. ADHD is a specific disorder which shows deficits in sustained attention, behavioral inhibition, resistance to distraction, and the regulation of one’s activity level to the demands of a situation (hyperactivity or restlessness). The interactive fairy tale system implemented on the Unity3D engine is expected to keep track of a player's time-varying brainwave and motion logs through NeuroSky’s MindWave Brain-Computer Interface (BCI) and Microsoft’s Kinect motion sensing technology. The proposed system helps us take a closer look at the player's behavior than performing a video shoot or direct observation. In addition, as the system keeps the observed data, it is possible to constantly track the changes on the player's brainwave and behavior, and synthetically assess the effect of the proposed approach from many different aspects.
