조병렬 한국교통대학교 2020 한국교통대학교 논문집 Vol.55 No.-

This study is a change in pH that can be most easily measured during the denitrification process when biologically denitrifying industrial waste containing high concentration nitrate nitrogen using microorganisms for industrial waste generated during chemical treatment using an alkali solution for NOx capture. The properties were analyzed according to the cation type. As a result, if an alkaline solution is used for nitrogen capture, if biological denitrification is considered as a post-treatment, it is advantageous to capture nitrate nitrogen with a solution having a large electronegativity of cations

This study has conducted to estimate the vulnerability assessment of climate change for Boeun-gun. The climate change vulnerability assessment analyzed using LCCGIS(Local climate change adaptation toolkit based on GIS) program. Meteorological data used the RCP(Representative concentration pathways) scenarios provided by Meteorological administration. This study used to determine the priority of the policy for Boeun-gun climate change action plan. However, the assessment results are not reliable because the most of the indices applied to LCCGIS have the limits. Results from this study are contribute to assess vulnerability to climate change reflecting on Boeun-gun characteristics.

This study is a biodenitrification for synthetic industrial waste with high ammonium nitrate(NH_(4)NO_(3)) concentration using Psudomonas halodenitrifications sp. nov. The experiment carried out biodenitrification using carbonaceous substrate from acetic acid in batch reactor under various experimental conditions such as pH, A/N(acetic acid/nitrate) ratio, temperature, rpm and concentrations of nitrate etc. It was found the possibility that biodenitrification is able to denitrify the industrial waste included with high nitrate nitrogen concentration. Optimal conditions for cell growth and biodenitrifications were as follow; pH range; 6.5-8.5, Temperature; 30℃, Acetic acid/Nitrate ratio; 1.0 and rpm; above 20, respectively.

ABSTRACT This study analyzed the monthly and seasonal characteristics by using variation coefficients, which are statistical data, on the chemical element composition and calorific value of domestic wastes. They are the basis of incineration treatment. In the case of detached house and apartment house, the coefficient of variation for chemical composition and heating value is in the range of 0.92 for the minimum and 1.2 for the maximum. In the case of detached house and apartment house, seasonal coefficients of variation for low and high calorific values were found to be different.

This study has conducted to estimate the vulnerability assessment of climate change for Goesan-gun. The vulnerability assessment was carried out to establish Goesan-gun climate change action plane. The climate change vulnerability assessment analyzed using LCCGIS(Local climate change adaptation toolkit based on GIS) program. Meteorological data used the RCP(Representative concentration pathways) scenarios provided by Meteorological administration. This study is used to determine the priority of the policy for Goesan-gun climate change action plan.

For each local town (3 cities and 8 counties) affiliated with Chungbuk provincial government, characteristics of greenhouse gas (GHG) analyzed and emission areas were drawn to establish mitigation policies. Regional emissions for Chungbuk province had the following order; Danyang > Cheongju > Jecheon > Cheongwon. Danyang, Jincheon, Eumseong and Yeongdong having relatively higher emissions in Chungbuk province were influenced by the emission from industrial process, electric power and land category. Greenhouse gas emission per capita was highest in the Danyang(269.4∼358.9 ton/yr . capita) by contribution of industrial process category. Regional emissions of Goesan, Jincheon and Eumseong showed higher yearly variation. Regional greenhouse gas emission characterizations classified with as follows: urban, industry, urban and industry, rural, land.

한국 재래산양 34두로부터 체중에 따른 도체 및 부산물 생산량과 정육율을 조사하였다. 생체중이 13.3kg에서 33.4kg까지 증가함에 따라 도체율은 35.32%에서 45.94%까지 상승하였다. 생체중(X)과 도체율(Y)의 관계는 Y=-4.537 +4.049X-0.067X2으로 추정되었으며 생체중 28KG에서 도체율(48.7%)이 가장 높았다. 도체중이 4.70KG에서 15.34KG으로 증가에 따라 정육율도 64.05%에서 74.31%로 증가하였다. 도체중(x)과 정육율(y)의 관계는 Y= 50.162+3.533X-0.127X2으로 추정되었으며 도체중 13.9KG (생체중30KG)에서 정육율(74.7%)이 가장 높았다. 따라서 재래산양의 적정 도살 시기는 생체중 30KG 내외가 적당할 것으로 사료된다. Thirty-four heads of Korean native goats were used to investigate the yields of carcass and by-products and lean-meat percentage as influenced by live weight. The dressing percentages were increased 35.32% to 45.94% with increasing live weight from 13.3kg to 33.4kg. The regression equation of dressing percentare(Y) on live weight(X) was Y= -4.537 + 4.049X - 0.076X2 and the highest dressing percentage(48.7%) was found at 28kg of live weight. The lean-meat percentages were increased 64.05% to 74.31% with increasing carcass weight from 4.70kg to 15.34kg, The regression equation of lean-meat percentare(Y) on carcass weight(X) was Y =50.162+3.533X-0.127X2 and the highest lean-meat percentage(74.7%) was found at 13.9kg of carcass weight (30kg of live weight). Therefore, it is considered that the optimum slaughter weight of Korean native goat is around 30kg of live body.

In this study, the classified researches the artificial and natural flaws in welding pails are performed using the pattern recognition technology. For this purpose the signal pattern recognition package including the user defined function was developed and the total procedure including the digital signal processing, feature extraction, feature selection and classifi-er selection is treated by bulk. Specially it is composed with and discussed using the statistical classifier such as the linear discriminant function the empirical Bayesian classifier. Also, the pattern recognition technology is applied to classifica-tion problem of natural flaw(i.e multiple classification problem - crack, lack of penetration, lack of fusion, porosity, and slag inclusion, the planar and volumetric flaw classification problem). According to this results, it is possible to acquire the recognition rate of 83% above even through it is different a little according to domain extracting the feature and the classifier.
