We examine the awareness of the facility managers in Korean universities and colleges over the global climate change and over the national greenhouse gas (GHG) energy target management program via a questionnaire survey. The result shows that the survey participants maintain high awareness on global and national issues including the climate change and the concept of the national GHG management framework. On the other hand, the responsibility of universities and colleges associated to these issues is not recognized as well, showing the necessity for further education. Additionally, important implications on the direction and the major factors that should be considered during the development of a GHG management program for universities and colleges are deduced from the result of the survey. In order to be effective in universities and colleges, a GHG management program must be able to estimate the present level of emissions accurately, to address campus-specific emissions characteristics, and to facilitate ease use for generic users. At the same time, active supporting services including education and promotion should be incorporated. The survey result can be utilized as basic data in guiding the future development of effective GHG management programs.

In this study, city gas is the most commonly used in homes, and gas accidents are increasing as demand increases. Among them, accidents due to user carelessness are the most and we try to provide information by establishing scenarios to effectively prevent this. The gas leak in the home is an enclosed space, and the appropriate Gaussian model is applied. As smart home control technology is developed by the 4th industrial revolution, it will make a foundation to provide information through program to predict and prevent gas leakage accidents and apply it to smart home safety platform.

worker-centered safety management for hazardous areas in the plant is required. The causes of gas accidents in the past five years are closely related to the behavior of the operator, such as careless handling of the user, careless handling of the suppliers, and intentional, as well as equipment failure and accident of thought. In order to prevent such accidents, real-time monitoring of hazardous areas in the plant is required. However, when installing a camera in a work space for real-time monitoring, problems such as human rights abuse occur. In order to prevent this, an infrared camera with low resolution with low exposure of the operator is used. In real-time monitoring, image analysis is performed using CNN algorithm, not human, to prevent human rights violation.

Currently, some urban gas companies are conducting their own gas AMI meter verification projects, along with the demonstration of gas AMI (Advanced Metering Infrastructure) meters under the supervision of the government. There are many positive factors such as remote meter reading and ensuring user gas safety through AMI meter installation, but on the other hand, there are also many problems such as battery discharge, expensive price, and decreased reliability of remote meter data. This study sought various improvements in gas AMI meters along with prevention of serious civil disasters by preemptively eliminating structural safety problems and potential risks from gas leakage due to the expansion of gas AMI meters, and it is expected that this study will contribute to the government's policy to advance gas AMI.

People store information not only in their Drain but also material things. Norman called it knowledge in the world. The general way to store the information is to paste labels. 4 burner gas range force user to make conceptual model between burner and switch to see labels. but those are cognitive stress. Norman suggested spatial analogies for natural mapping between display and control. However the way of his methods in spatial analogies was not compatible with kitchen atmosphere. To solve those problems 1 suggested color coding . This study hypothesized that the mapping between burner and switch is realized by color coding. To testy the hypothesis 1 compared A group using general gas range with B group using color coded gas range. The result showed difference between A and B in accuracy ( F (1, 38) = 17.892, p < 0.01) and response time ( F (1, 38) = 6.726 p < 0.05). The result of this test is to certify that color coding affect peoples by presenting the difference accuracy and response time. As result this study presents that color coding can be compatible the product having importance to certify in the design process.

내연기관 자동차는 연료 소모로 인해 대기 중에 유해 물질과 온실가스를 배출한다. 반면에 전기 자동차는 전기로 작동되어 대기 중 오염을 줄이고 친환경적인 운행을 제공한다. 전기차 대여 시스템을 도입함으로써, 사용자들에게 친환경적인 교통수단을 이용할 수 있는 기회를 제공하고, 탄소 배출량을 줄이는 데 크게 기여할 수 있기에 해당 연구를 진행하였다. 이 연구에는 React 기반의 Next.js 웹 프레임워크를 이용하여 클라이언트 측과 서버 측 렌더링을 지원하고 사용자들에게 빠른 반응 속도와 사용 편의성을 제공한다. Bootstrap을 이용하여 사용자 인터페이스(UI)를 개발하고, 전기 자동차 대여 서비스에 필요한 화면을 구성하였다. 또한 Node.js 기반의 Express.js 웹 프레임워크를 이용하여 서버 사이드 로직과 RESTful API를 개발하는 데 사용하고 데이터베이스와의 통신, 사용자 인증, 대여 정보 관리 등을 처리하였다. 이러한 기술적 개발을 통해 전기 자동차 대여 시스템은 실용적이고 효율적인 서비스를 제공하며, 환경 보호와 탄소 배출 감소에 기여할 수 있는 프로젝트라고 볼 수 있다.

국내외 대규모 산업시설은 유해물질과 직 간접적으로 밀접하게 관련되어 유해물질 누출사고는 막대한 물적, 인적 피해를 발생시키며 누출물질, 저장시설, 대기 상태에 따라 유해물질 확산 속도 및 범위가 다르기 때문에 이를 예측하는 대기확산 시스템이 필요하다. 또한 기존의 대기확산 시스템은 산업시설 구조물 설계 단계에서 안전성을 확인하는 시뮬레이션용으로 사용되었기 때문에 누출사고 발생 시 즉각적인 처리와 대응이 어려우며 전문적 지식수준의 사용자 입력을 요구한다. 본 논문은 에너지 플랜트 환경의 특수성과 효율성을 고려하여 운영 중인 시설에 적용 가능한 대기확산 시스템 연구를 목적으로 한다. 이를 위하여 신속하고 효율적인 대기확산 모델을 선정 정의하고 융통성 있는 대기확산 시스템의 구성요소를 컴포넌트화하여 구현하였으며 사고 발생 시 빠르게 피해범위를 예측할 수 있는 실시간 대기확산 시스템 설계 방안을 제시하였다.

Micro gas turbine engine is well known as a power plant of unmanned aerial vehicle and a small scale emergency generation system and also, it is significant as initial research of large gas turbine and educational purpose of gas turbine. Many sort of Micro gas turbine test set for education is produced by several manufacturers, but all of the engine control system of them is separated with data acquisition system; moreover, the engine control algorithms are inaccessible and related variables could not be collected. In this investigation, the Integrated Modifiable Test Rig which has modifiable engine start-up, drive and situational control logics is developed by LabVIEW with I/O devices and it provides wide experimental applicability to studies of dynamic characteristics of fuel system and combustion instability.

본 논문에서는 BIM TOOL 중 하나인 AUTODESK사의 Revit Softwere를 활용하여 건축물에서 필수적으로 사용하고 있는 전기 설비 중 조명설비를 대상으로 전력소비에 따라 발생하는 온실가스인 이산화탄소($CO_2$), 메탄($CH_4$), 아산화질소($N_2O$) 배출량을 추정하여 건축물 에너지절감의 필요성을 강조하고 증명하고자 한다. BIM을 적용 할 수 있는 설계, 시공, 유지보수 외에 사용자의 전력소비에 따른 배출량을 연계한 데이터를 추출하여 온실가스 감축을 위한 전력절감의 TOOL 활용과 국가 정책, 제도 및 지침에 적극 활용되기를 기대한다.
