전병일 新羅大學校 2003 論文集 Vol.52 No.-

This study was conducted to investigate the meteorological element and ozone concentration by aircraft and ozonesonde measurement at Washington State, USA at August 20, 2001. According to two measurement, the vertical profile of dry temperature and relative humidity concentration in interior of mixed layer was 3∼4ppb. The strong effectivity of ozone concentration showed in mixed layer between aircraft and ozonesonde measurement, but another modification works need to use these data in upper layer.

전병일 신라대학교 자연과학연구소 2000 自然科學論文集 Vol.8 No.-

A series of meteorological observation using automatic weather system(AWS) carried out to investigate characteristics of nocturnal meteorological characteristics on June 21 ∼ 22, 1999 at Buljeondong mountain slope, Kyungbuk. The measured variables include dry temperature, relative humidity, wind direction and wind speed. All the monitors are operated automatically. There is also a data logger which is programmed to collect and automatically record data. Measurements are taken and stored in the data logger every 1 minute. Dry temperature at valley was higher than mountain except for about 1 hour(0557 ∼0654LST, June 22, 1999) because of high lapse rate at mountain. Relative humidity was distributed 4 parts according to up and down of wave shape of relative humidity. And relative humidity for early morning(0600 ∼0700LST) decreased in inverse proportion to dry temperature. Wind direction was distributed as relative humidity. The wind direction of valley and mountain had the opposite direction. Wind speed at valley from sunset to next day morning was lower than mountain, but that of valley after sunrise was higher than mountain.

전병일,황정호,박상욱,신동훈,류태우 한국연소학회 2005 한국연소학회지 Vol.10 No.1

In this study, we investigated characteristics of a gas flow and a combustion property during the combustion of a RDF in a pyrolysis melting incinerator with disposal rate of 30 kg/hr. The RDF was pyrolyzed through the pyrolysis chamber at 600℃ of the chamber surface without oxygen condition. The pyrolysis gas was injected in the combustion chamber. It was burned by means of the staged combustion that was injecting secondary and tertiary air in the combustor. We measured the temperatures and the gas components in the combustion chamber while maintaining the air-fuel ratio of 1.3. Finally, we confirm that additional air injection, secondary and tertiary air ratio, was the most important factor to reduce NOx.

Today, with the advance of Information and communication technology, ‘Smart, connected’ toys, which apply technologies related to IoT (Internet of Things) to traditional toys, are emerging and rapidly growing. This research aims to analyze the tendencies and limitations of smart, connected toys through exploring the representative cases of smart, connected toys based on characteristics of ICBM (Internet of Things, Cloud, Big-data, and Mobile) technology. For this study, we begin by understanding literature research about smart, connected toys and ICBM technology. Then, we extracted the characteristics of ICBM technology for connecting physical and digital environments through investigating cases to which ICBM technologies are applied. Based on the extracted characteristics, the case studies of smart, connected toys were conducted. In this research, we explore the level of ICBM technology application and limitation to smart, connected toys. We expect this research will contribute to providing guidelines for developing smart, connected toys based on the characteristics of the latest technology. 오늘날 정보통신 기술의 진보에 따라 전통적인 완구에 사물인터넷 관련 기술이 융합된 스마트, 커넥티드 완구가 출현하고 있으며 빠르게 성장하고 있다. 본 연구는 ICBM (Internet of Things, Cloud, Big-data, and Mobile) 기술 특성을 바탕으로 스마트, 커넥티드 완구의 대표적인 사례 분석을 통해 스마트, 커넥티드 완구의 경향과 한계점을 파악하는 것을 목적으로 한다. 본 연구를 위하여 스마트, 커넥티드 완구의 개념 및 현황과 ICBM 기술에 대한 문헌 연구를 수행한 후, ICBM 기술이 적용된 사례를 분석하여 물리적 공간과 디지털 환경을 연결하기 위한 기술 특성을 도출하였다. 도출된 기술 특성을 기반으로 스마트, 커넥티드 완구의 사례 분석을 수행하였다. 이를 통해 본 연구에서는 스마트, 커넥티드 완구에 적용된 ICBM 기술의 특성 정도와 한계점을 파악하는 것을 최종 목표로 한다. 본 연구는 최신 기술의 특성을 기반으로 스마트, 커넥티드 완구 개발을 위한 지침을 제공할 수 있을 것으로 기대된다.

부산연안역의 해풍전선 특성과 대기오염농도에 미치는 영향

전병일 新羅大學校 1998 論文集 Vol.45 No.-

We have analyzed focusing on the characteristics, speed and width of sea breeze front in Pusan coastal area using the meteorological data for March 1, 1992 to June 30, 1992 observed at Kimhae air force meteorological station because the presence of the front has important effects on the distribution of air pollution. Among the 44 sea breeze days for research period, there were 27 sea breeze front days(61%) with steep variation of meteorological parameters(wind direction, wind speed, temperature, dew point temperature, air pressure, relative humidity). And when sea breeze front occurrenced, the diurnal range of temperature was 12.5℃. The width of the sea breeze front was from 61m to 3494m, mean width was 886±971m(standard deviation). And the mean speed of sea breeze front was 3.18m/s±2.50m/s(standard deviation). The SO2 concentration of sea breeze front days showed higher than monthly mean concentration, 14ppb at Gamjeondong, 8ppb at Kwangbokdong and 7ppb at Deokcheondong, respectively. From the SO2 concentration diurnal change of sea breeze front days, the highest concentration the increment showed at earlier morning approximately 10ppb. The structure and inland penetration of sea breeze front should be taken into account whenever a model is to be compared with detailed feild measurements.

We have analyzed focusing on the characteristics, speed and width of sea breeze front in Pusan coastal area using the meteorological data observed for May 30, 1992 at Kimhae air force meteorological station and the mouth of the Nakdong River because the presence of the front has important an effects on the distribution of air pollution. The inland penetration of sea breeze front was recognized by steep variation of meteorological parameters(wind direction, wind speed, temperature, dew point temperature, air pressure, relative humidity) before and after its passage, the speed and width of the sea front observed at Kimhae air force meteorological station was 2.4m/s and 504m, respectively. According to Pibal observation, the inland penetration of sea breeze was recognized, and the level of sea breeze was about 600m. The structure and inland penetration of sea breeze front should be taken into account whenever a model is to be compared with detailed field measurements.

This study considered the change of meteorological environment according to construction of Nakdong-river estuary barrage using to Kimhae air force meteorological data. The artificial lake cause frequent radiation fog and visibility degradation on marginal region. The mean temperature at the time after the construction(1988∼1996) of estuary barrage was 13.9℃ while before the construction(1975∼1983) was 13.7℃. The minimum temperature after the construction was 9.4℃ while before the construction was 9.3℃. The annual mean precipitation after the construction of estuary barrage was 1.297mm while before the construction was 1.356mm. The change of relative humidity after the construction increased 8% annually than that of the percent before the construction. The day of radiation fog after the construction was 84.4 days while before the construction was 62.3 days. The fog occurrence rate according to construction of estuary barrage increased obviously.
