최근 몇 년 동안 화재 감지기의 개발은 화재라는 치명적인 재난으로부터 인명과 재산을 보호하기 위해 많은 연구자의 관심을 끌었다. 그러나 시간적 의존성, 화재 유형의 다양성에 따른 신호 패턴의 복잡성과 같은 화재 센서 신호의 몇 가지 고유한 특성으로 인해, 화재 모니터링 관련 연구는 난항을 겪고 있었다. 본 연구에서는 다차원 채널의 화재 센서 신호를 통해 얻은 데이터를 활용하여, 다양한 유형의 화재 상황을 실시간 수준에서 정확하게 분류하는 딥러닝 기반의 새로운 접근 방식을 제안한다. 본 연구의 기여는 센서 데이터의 시계열적 특성과 다차원 채널 센싱 데이터의 복잡성을 고려한 stacked LSTM 모델을 개발하여 기반의 화재 식별을 위한 새로운 화재 모니터링 프레임워크를 개발하여 기존 화재 감지기를 개선하는 것이다. Several researchers have been drawn to the development of fire detector in recent years, to protect people and property from the catastrophic disaster of fire. However, studies related to fire monitoring are affected by some unique characteristics of fire sensor signals, such as time dependence and the complexity of the signal pattern based on the variety of fire types,. In this study, a new deep learning-based approach that accurately classifies various types of fire situations in real-time using data obtained from multidimensional channel fire sensor signals was proposed. The contribution of this study is to develop a stacked-LSTM model that considers the time-series characteristics of sensor data and the complexity of multidimensional channel sensing data to develop a new fire monitoring framework for fire identification based on improving existing fire detectors.

The purpose of present study is to analysis the Characteristics of fuel economy and Green house gases due to the driving mode conditions of The hybrid electric vehicle(HEV). HEVs are divided into mild and power types according to the their functions. mild type HEVs are inexpensive because they do not need to implement a pure electric mode. Power type HEVs are more expensive but has also better fuel efficiency. In the present paper, the test results for the gasoline vehicle using FTP-75 mode and HWFET are present.

강은정,고병섭,김호경,Kang, Eun-Jung,Ko, Byoung-Seob,Kim, Ho-Kyoung 한국생약학회 2000 생약학회지 Vol.31 No.4
Two sinapic acid esters were isolated from the methanol extract of Raphani Semen. The structures were elucidated on the basis of spectroscopic methods $(^1H-NMR,\;^{13}C-NMR,\;HMQC,\;^1H-^1H\;COSY\;and\;HMBC)$ and were identified as methyl sinapate (1) and ${\beta}-D-(3-O- sinapoyl)fructofuranosyl-{\alpha}-D-(6-O-sinapoyl)glucopyranoside$ (2). Compound 1 was first isolated from the genus of Raphanus.

Objectives : This review was conducted to validate the effectiveness and safety of herbal medicine combined with conventional therapy for rosacea. Methods : Randomized controlled trials(RCTs) reporting the effects of herbal medicine treatment on rosacea were searched through eight electronic databases from 2016 to March 17, 2020. This study collection and data extraction were performed by two independent reviews. The Cochrane risk-of-bias tool was used for the evaluation of the risk of bias in all included RCTs. Mean differences(MD) and Risk ratio(RR) of 95% Confidence intervals(Cls) were calculated and data synthesis was conducted using Review Manager(RevMan, ver.5.4) Results : Eighteen RCTs were included and all trials compared the combined therapy of herbal medicine with conventional western therapy to conventional therapy alone. The effective rate of the combination of herbal medicine with western medicine(RR 1.20, 95% CI : 1.13-1.28, p<0.00001, I<sup>2</sup>=0%), the effective rate of the combination of herbal medicine with laser-based therapy(RR 1.12, 95% CI : 1.04-1.21, p=0.004, I<sup>2</sup>=18%) and the effective rate of the combination treatment group using herbal medicine, western medicine and external drugs were all statistically higher that of the control group(RR 1.19, 95% CI : 1.11-1.28, p<0.00001, I<sup>2</sup>=0%). The score of non transient erythema(MD -0.36, 95% CI : -1.01 0.29, p=0.27, I<sup>2</sup>=93%), flushing(MD -0.69, 95% CI : -0.97, 0.41, p<0.00001, I<sup>2</sup>=32%), papules or pustules(MD 0.10, 95% CI : -0.15, 0.35 p=0.44, I<sup>2</sup>=0%) were also seen in the herbal medicine and western medicine combination group. The overall risk of bias of the included studies was some concerns. No serious adverse effects were observed. Conclusions : This review found the safety and effectiveness of the combined therapy of herbal medicine with conventional western therapy for rosacea.

Recently EU has been recognized that there is a difference of emission quantity between emission certification test mode and real-road driving test. Accordingly the European Commission is currently preparing to require real-road testing as part of the passenger car type-approval process in the EU. vehicle manufacturers from 2017 are expected to test new vehicles not only under laboratory conditions but also on the real-road, using PEMS equipment. Therefore the purpose of this study is to analyze the emission and Fuel Economy of CVS-75 mode test using chassis dynamometer and RDE test using PEMS equipment by PHEV passenger car.

Objective: Seoul City has implemented the Safe Pharmacy in 2013. This study aimed to ascertain the success factors of the smoking cessation service of the Safe Pharmacy. Methods: The data for the smoking cessation registration cards were obtained from the pharmacies which participated in 2014 Safe Pharmacy. The sample included 289 smokers in 6 districts who participated at least one sessions of smoking cessation service. the service included both behavioral intervention and nicotine replacement therapy. In order to identify the effectiveness of the smoking cessation service, logistic regression analysis was used. The dependent variable was the success of quitting smoking at the 4th week. The independent variables included age, sex, employment, chronic disease, district, smoking amount, registration path, supporters for quitting smoking and number of service sessions. Results: Fifty eight point eight percent of the sample successfully quit smoking at the 4th week. Unemployment, higher smoking amount, and less service sessions were negatively related to the success of quitting smoking. There were differences in the success rate across districts. Age, sex, chronic disease, registration path, and anti-smoking supporters were not related to the success rate. Conclusion: Pharmacy can be an effective community resource for smoking cessation. Factors that could increase the effectiveness of smoking cessation service of the Safe Pharmacy and possible ways to enhance the participation of pharmacies in smoking cessation services were also discussed.

Currently the vehicle exhaust gas regulation has been strengthened, Research to improve the exhaust gas after-treatment device development technology and the exhaust performance of the vehicle is making efforts In order to satisfy the regulatory. The purpose of this study is analysis to Characteristics evaluation of fuel economy and emission according to driving mode conditions of The vehicle by fuel type. The test vehicles were selected by each of the fuel according to the difference in displacement volume. These were used four representative mode(FTP-75, NEDC, US06 and SC03) in order to evaluation fuel economy and emission gas. Domestic certification emissions measurement test mode was conduct after the vehicle was soaking for a long time. It is standard condition. Additionally, the test conditions were carried out for warm-up air conditioner condition. Warm-up air conditioner condition was performed the test while it is running the air conditioner after the engine fully warmed up.
