In this research, I performed rainfall monitoring by selecting the spot which can represent high altitude cool farm region in recent 3 years, and tried to understand the characteristic of outflow of non-point pollutants coming from high altitude cool farm region. As a result, it was shown that reducing rainfall runoff in highland farm area can reduce non-point pollution load and should consider priority to reduce runoff through management resources when selecting abatement method. Additionally, it is judged that reduction method related to base run-off should be selected by performing research on material motion of TN.

In this paper, we propose an intelligent camera for multiple body temperature detection. The proposed camera is composed of optical(4056*3040) and thermal(640*480), which detects abnormal symptoms by analyzing a person's facial expression and body temperature from the acquired image. The optical and thermal imaging cameras are operated simultaneously and detect an object in the optical image, in which the facial region and expression analysis are calculated from the object. Additionally, the calculated coordinate values from the optical image facial region are applied to the thermal image, also the maximum temperature is measured from the region and displayed on the screen. Abnormal symptom detection is determined by using the analyzed three facial expressions(neutral, happy, sadness) and body temperature values. In order to evaluate the performance of the proposed camera, the optical image processing part is tested on Caltech, WIDER FACE, and CK+ datasets for three algorithms(object detection, facial region detection, and expression analysis). Experimental results have shown 91%, 91%, and 84% accuracy scores each.

The objective of this paper was to quantitatively analyze the effect of concentrated animal feeding operations (CAFO) NPS pollution on a small watershed water quality. Monitoring was conducted from March to October, 2013. Monthly flow rate and selected water quality at each monitoring site were measured during dry days. Rainy day monitoring also was conducted. Modeling was conducted to evaluate the effect of CAFO NPS pollution on the water quality at the watershed outlet. The highest and mean concentration of selected water quality indices during rainy days were higher than those in dry days in general. The highest TN concentration measured at the CAFP pollution discharge point was 237.831 mg/L. The results revealed that the CAFO NPS pollution sources could be equally blamed for the water quality degradation of the stream. However, the effect of the NPS pollution from CAFOs seemed not to be very influential to the watershed water quality at the outlet. SWAT modeling revealed that the TN load was reduced by 18.95 %, 23.39 % and 30.53 % at the watershed outlet if the TN load at the CAFO NPS pollution discharge point reduced by 20 %, 40 % and 60 %, respectively. It was thought that the natural attenuation processes played an important role. The modeling was based only on the assumption of the load reduction and not verified by the monitored data. Therefore, it was suggested that a long term monitoring studies for the evaluation of the impact of CAFO NPS pollution on the watershed water quality be conducted.

Various Best Management Practices (BMPs) have been suggested to reduce soil erosion and non point source (NPS) pollutant loads from agricultural fields. However, very little research regarding water quality improvement with No-till (NT) has been performed in Korea. Thus, effects of NT were investigated in this study. The objective of the study was to investigate the effect of NT on the surface runoff and sediment discharge in a field. Eight experimental plots of $5{\times}30m$ in size and 3 % or 8 % in slope prepared on gravelly sandy loam soil were treated with Conventional-till (CT) and NT. Runoff and NPS pollution discharge were monitored and compared the treatments. The amounts of rainfall from 13 monitored events ranged from 28.7 mm to 503.5 mm. The runoff amount was reduced by 17.6~59.2 % in 3 % NT and 29.6~53.2 % in 8 % NT. The average NPS pollution loads of the 3 % NT plots and 8 % NT plot were reduced about 45.1~89.2 % and 47.7~98.0 % compared to those of the CT plots, respectively. This research revealed that NT can reduce the NPS pollution loads substantially as well as increase the crop yield. Runoff and NPS pollution loads reduction by NT method could be contribute to improve the water quality of streams in agricultural regions.

본 연구에서는 반려견의 먹이 섭취 환경에 따른 반응 차이에 대하여 알아보았다. 실험에 사용한 견종으로는 Toy poodle (2016년생, 중성화O, 남) 1마리, Golden Retriever (2012년생, 중성화X, 여/2018년생, 중성화O, 여) 2마리 총 3마리이다. 실험에 사용한 먹이(훈련용 트릿)는 총 30개이다. 실내 장소로는 동물행동과학연구실과 연구원 본인의 집, 실외 장소로는 제 2과학관 앞과 아파트 단지 내 공원에서 실험이 진행되었다. 기록 측정은 반려견이 먹이를 인식했을 때를 기준으로 하여 내부에 있는 먹이 10개를 다 먹을 때까지의 행동을 영상으로 기록하였다. 견 종 1마리당 2가지 환경 조건에서 관찰해 6번의 영상이 기록되었고, 그 영상들을 분석하여 견종마다 코를 핥는 횟수, 먹이를 먹는 데 걸린 시간, 먹이에 집중하지 않은 시간 등을 정리하였다. 그 결과, 세 마리 모두 내부보다 외부에서의 먹이 섭취 시간이 길었으며, 먹이 섭취 시 초당 코를 핥는 횟수도 외부에서 더 증가하였다. 본 연구 결과는 환경의 변화가 반려견에게 어떤 영향을 주는지 알아보고 그들의 입장을 이해해 보기 위한 자료로 이용될 것으로 예상된다. In this study, the difference in response according to the food intake environment of dogs was investigated. The dogs used in the experiment were one Toy poodle (born in 2016, neutralized O, male) and two Golden Retriever (born in 2012, neutralized X, female/2018), neutralized O, female. The total number of food (training treatments) used in the experiment was 10. Experiments were conducted in front of the Animal Behavior Science Laboratory and the researchers own house as indoor places, and in front of the 2nd Science Museum as outdoor places and in the park in the apartment complex. The record measurement was based on the time when the dog recognized the food, and the behavior until eating all 10 internal prey was recorded as an image. Six images were recorded by observing under two environmental conditions per dog, and the images were analyzed to summarize the number of times each dog licks its nose, the time it took to eat, and the time it did not focus on feeding. As a result, all three dogs had a longer time to eat outside than inside, and the number of times they licked their noses per second increased from outside. The results of this study are expected to be used as data to find out how environmental changes affect dogs and to understand their positions.

가축분뇨로부터 발생하는 비점오염물질은 발생, 처리, 유통에 이르기까지 전 과정에서 다양한 경로로 배출된다. 그러나 우리나라 축산비점오염원은 관리 주체가 모호하여 규명이 어렵고 접근 또한 어려워 그 영향이 정량화 되지 않아 관리 및 대책 마련이 어렵다. 이에 본 연구에서는 유역면적의 70% 이상이 산림으로 구성되고, 유역 내에 축산농가가 포함이 되어 있는 지역을 선정하였다. 선정된 유역에서 경종 및 축산 비점오염원이 유역에 미치는 영향을 정량적으로 분석하고자 하였다. 연구 대상지역은 2,000두 이상의 돼지를 사육하고 있으며, 돈가에서 발생하는 분과 뇨는 인근 퇴비화시설과 개별처리시설을 통해 처리하고 있다. 축산농가에서 발생하는 비점오염물질이 하류에 미치는 영향을 정량적으로 분석하기 위해 2013년 2월부터 7월까지 주기적(월 1회) 또는 강우시 유량과 수질농도를 분석하였다. 대상유역 말단의 수질 분석 결과 비강우기에 SS 0.33~4.67 mg/L, COD 0.8~25.0 mg/L, TN 1.818~10.212 mg/L, TP 0.007~0.425 mg/L의 범위로 나타났으며, 강우시 수질은 SS 0.8~107.3 mg/L, COD 10.4~112.8 mg/L, TN 3.884~7.801 mg/L, TP 0.002~0.452 mg/L의 범위로 나타났다. 강우시 수질항목의 최대값 및 평균적인 농도 값이 일반적으로 비강우시보다 높은 것으로 나타났다. 지점별 수질 농도 비교 결과 TN은 93.08 mg/L로 축산에서 발생하는 방류수에서 가장 높은 값을 나타냈으며, TP와 SS는 농경지에서 배출되는 유출수가 8.445 mg/L와 2,782 mg/L로 가장 높은 값을 보이는 것으로 나타났다. 모니터링 결과 축산과 경종 두 오염원 모두 하천의 부영양화를 유발하는 영양염류 발생 기여도가 큰 오염원인 것으로 나타났으며, 강우시 하천의 탁수 유발에 있어서는 농경지의 영향이 크게 미치는 것으로 나타났다. 그러나 경종과 축산 지점의 하천 수질오염 기여율에 대한 평가는 추가적인 장기 모니터링과 유출량을 고려한 정량적인 분석이 이루어져야할 것으로 판단된다. 장기적인 모니터링을 통한 본 연구결과는 축산에서 발생하는 비점오염관리를 위한 정책개발의 기초자료를 제공할 수 있을 것으로 기대한다.

The contemporary enlightenment has been believed as guaranteeing the better living of human beings, but, as people feel crisis, they came to be skeptical about it. Amidst this conflicting situation, a new name of new criticism called post-modern comes to surface. The post-modernism opens the mutually insulated sphere in which modernism was standardized and specialized, and recreated the newly expanded sphere by getting out of the establishment. The recreated, and expanded sphere appears in modern hair style, and following this, the meaning and technique of express are seen in a variety of ways. I have divided them into the mixing of popular culture and high class culture the overcoming of absolute power, and the technique of expressing anti-formalistic beauty, and examined them. The result of my examination is as follows. The mixing of high class culture and popular culture is the mixing of Otu Quitre and preta porte, and this showed the coppapse of the boundary of high class art and popular art. And the overcoming of absolute power was seen as that in which the confusion of sex, anticulture, and the style which had been alienated during that time in the third world are restoring. And the technique of expressing the antiformalistic beauty was seen in mixing and imitating, parady, and kicky.
