'그림'은 대상간의 상호소통을 위한 직관적인 방법이다. 사물의 모습이나 추상적인 개념을 2차원 공간에 그려서 의사를 전달하는 일은 대상의 특징에 대해 사회적 합의를 통한 고차원의 통념적 해석을 요구하는 언어학적 관점에 있어 문자기호 이전의 최하위 수준 인간중심적 언어이다. 본 연구에서는 사용자의 직관과 감성을 자극하는 인터페이스 요소의 요구에 대응하여 점차 지능화되는 디지털 매체와 사용자간의 인터랙션을 보편화된 인간중심적 관점으로 접근해 '그림'기호의 통념적 해석이론을 정립하고 HCI 요소로 활용하기 위한 방법론을 제시한다. 이를 통해 디지털 미디어 공간을 구현하여 사용자에게 새로운 경험을 제공함으로서 감성을 자극하고 그 효과를 검증한다. 'Scribble' for interactions between the target is an intuitive way. The appearance of things or abstract concepts by drawing on two-dimensional space, communicating what the social consensus about the nature of the target through the high-level linguistic terms that require interpretation tongnyeomjeok a letter to the lowest level of the previous symbol is a human-centric language . In this study, to stimulate your intuition and emotional response to the growing needs of interface elements, digital media and user intelligent interactions between hwadoeneun pervasive human-centric approach in terms 'picture' theory formulation and interpretation of symbols HCI elements tongnyeomjeok presents a methodology for taking advantage. Through which to implement the digital media space by providing new experiences to stimulate the senses and to verify its effectiveness.

This research is to eliminate the need for conventional high density plant factory’s artificial light source such as LED to reduce the initial investment of the light source installation as well as the operation cost. Provision of solar light into the multi-layer vegetable cultivation facilities and collecting maximum and sustainable sunlight without too much loss by tracing solar path and properly distributing it through careful control during daytime are crucial for realizing the investigated rooftop light shelf system for multi-layered vegetable cultivation. In this study, we developed an innovative way of effectively allocating sunlight inside even to otherwise shaded zone of a multi-layer vegetable cultivation facility. To prove the effectiveness of the system’s sunlight collection and distribution capability, both simulation and experiment in Daejeon are performed and the outcome is analyzed.

As the Photovoltaic system market increases, various technologies are emerging to improve system operation efficiency. Such additional systems of the power generation system are generally referred to as ‘Balance of System’, for example a panel cooling, a panel cleaning and a panel angle adjusting apparatus. In this paper, we discuss an algorithm to calculate the target temperature of cooling in response to changes in the installation environment conditions of the power generation system so that the efficiency improvement rate target set by the user can be achieved with respect to the control method of the cooling water injection system among various panel cooling apparatuses. In order to calculate the target temperature of cooling, the output enhancement coefficient is calculated experimentally based on the temperature change according to the solar radiation condition of the PV panel, and the required reduction temperature of each irradiation condition is calculated considering the efficiency improvement rate. In addition, the efficiency improvement ratio is calculated considering the installation condition of the general power generation system without a separate control group. The thermal performance coefficient of the PV panel test body for calculating the expected temperature of the PV panel is calculated experimentally. The target temperature of cooling is calculated as the sum of the expected temperature of the PV panel and the required reduction temperature, and the injection system that tracks the target temperature by cooling water injection is constructed and compared with the power generation improvement rate and the user setting efficiency improvement rate.
