요즈음 자동차가 많이 늘어나 생활이 편리해졌지만 교통체증, 주차문제말고도 심각한 대기오염으로 우리의 건강을 위협하고 있다. 우리가 추구하는 과학기술의 연구가 자연환경을 크게 오염시키는 결과를 초래한다면 이 연구를 거부할만한 양식을 가져야 하고 만약 그 연구를 계속해야 한다면 환경오염 처리방법도 함께 연구해야 할 것이다.

1953년에 밀러와 유리는 초기 지구 대기와 해양을 모사하여 단순한 기체 조합으로부터 유기분자를 얻었다. 생명의 기원을 논할 때 언급되는 밀러유리 실험을 교육 현장에서 활용하고 현대적으로 해석하고자 2014년에 Parker 등에 의해 재조명되어 단순화된 장치로 실험실을 설계하여 전기방전 실험을 진행하였다. 실험장치에 사용한 유리기구는 산, 염기로 각각 세척하고 200도씨 오븐에 건조하였다. 300ml 의 물을 반응 플라스크에 넣고, 83mmHg(11kPa) 압력의 진공상태에서 암모니아 100mmHg, 메탄 200mmHg, 질소 100mmHg를 주입하였다. 총 16일의 실험 기간중 66시간 방전을 하였다. 전기 방전 색이 하늘색에서 보라색으로 바뀌는 것을 확인하고 분광스펙트럼을 얻었으며, 시간에 따른 대기조성의 변화를 해석하고자 한다. 이 실험은 교내 창의연구활동 (R&E와 졸업개인연구)의 하나로 2015년부터 학생 주도적으로 진행되고 있다.

The purposes of the study are (1) to develop a Computer-Assisted Instruction (CAI) program to deal with middle school students' misconceptions on the concept of atmospheric pressure, and (2) to investigate the effects of the CAI on students' achievement and conceptual change. The findings of the study are as follows: (1) Misconceptions about atmospheric pressure found are similar to the ones identified in earlier studies, (2) A CAI program on atmospheric pressure was developed based on the students' misconceptions identified, and (3) The instruction using CAI program has very positive effects on students' science achievement and conceptual change.

A synthetic infrared image can be effectively utilized in various fields such as the recognition and tracking of targets as long as its quality is good enough to reflect the real situations. One way to improve its quality is to use the reference atmosphere which best describes atmospheric properties of regional areas. The east asian reference atmosphere has been developed to represent atmospheric properties of the east asia including Korean peninsula. However, few research has been conducted to examine the effects of this east asian reference atmosphere on the modeling and simulation. In this regard, this paper analyzes the effects of the east asian reference atmosphere on a synthetic infrared image. The research compares the atmospheric transmittance, the surface temperature, and the radiance obtained by using the east asian reference atmosphere with those of the midlatitude reference atmosphere which has been widely applied in the east asia. The results show that the differences of the atmospheric transmittance, the surface temperature, and the radiance between the east asian reference atmosphere and the midlatitude reference atmosphere are significant especially during the daytime. Therefore, it is recommended to apply the east asian reference atmosphere for generating a synthetic infrared image with targets in the east asia.

There has been an increasing trend in damaging by the Asian dust in spring. The continuous monitoring of the dust event with IR channels in geostationary satellite is very useful for forecasting and preventing the event. However, the monitoring with the IR channels revealed various problems associated with sensitivity. To eliminate these problems, we introduced a new concept of monitoring by constructing the background threshold values (BTV) and aerosol index (AI). This paper is about to test the reliability of this concept by applying to geostationary satellite, MTSAT-1R.

The elimination process of cloud-contaminated pixels is one of important steps before obtaining the accurate parameters of land and ocean surface from AVHRR imagery. We developed a 6step threshold method to detect the cloud-contaminated pixels from NOAA-14/AVHRR datime imagery over land using different combination of channels. This algorithm has two phases : the first is to make a cloud-free characteristic data of land surface using compositing techniques from channel 1 and 5 imagery and a dynamic threshold of brightness temperature, and the second is to identify the each pixel as a cloud-free or cloudy one through 4-step threshold tests. The merits of this method are its simplicity in input data and automation in determining threshold values. The threshold of infrared data is calculated through the combination of brightness temperature of land surface obtained from AVHRR imagery, spatial variance of them and temporal variance of observed land surface temperature. The method detected the could-comtaminated pixels successfully embedded inthe NOAA-14/AVHRR daytime imagery for the August 1 to November 30, 1996 and March 1 to July 30, 1997. This method was evaluated through the comparison with ground-based cloud observations and with the enhanced visible and infrared imagery.

Remote sensing becomes a new and core framework for the atmospheric sciences and closely related areas concerning with the ever-changing global environmental status. However, remote sensing in the Korea Meteorological Society is relatively new, where the first relevant paper is appeared in 1983, as well as is an area with relatively limited number of research groups. Here, we review and summarize some of the key progress in this area within Korea Meteorological Society focusing on the areas of satellite, radar, and ground based remote sensing such as lidar, spectrometer and sun photometer. Overall, the area is shown to have the most significant progress occur along with the acquisition of the key infra structures such as the COMS (Communication, Ocean and Meteorological Satellite) and S-band radar system led by Korea Meteorological Administration in early 2000. After that, the area has quickly developed into a status playing important roles to lead and support the overall activities in the atmospheric measurements. It is expected that the importance and role of the remote sensing will increase in the coming years.

A valuation of air pollution is critical for relevant policy-making for the public and research direction. This study conducted a willingness-to-pay (WTP) survey using contingent valuation method (CVM) in Seoul Korea. In detail, this study puts an emphasis on its temporal changes referred on two surveys conducted in 2014 and 2019. In reference to the previous studies in 2002, our survey indicated that the public awareness of air pollution and interests on its sources and solutions increased noticeably. Our survey showed that WTP increased significantly from 2588 to 4827 and 8240 Korean Won $month^{-1}$ in 2002, 2014, and 2019, respectively. Moreover, the percentage of respondents to pay the WTP also increased from 48% to 68% and 79% in 2002, 2014, and 2019, respectively. Our analysis based on the number of Google search on particulate matters (PMs) strongly suggests that such the noticeable increases of the public attention to air pollution is well accorded with the moment of the announcement of a standard for ultra-fine particles and the start of PM prediction in late 2013. But the Google search rate grew about 16.7 times in 2009 compared to 2014, which is much larger than the growth rate of interest and WTP between 2014 and 2019. Our results shed light on policy decision for the right person in the right place on the right time in the era of air pollution.
