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.
임상간호사의 간호근무환경, 감정노동 및 자아탄력성이 간호업무성과에 미치는 영향

본 연구는 임상간호사의 간호근무환경, 감정노동 및 자아탄력성이 간호업무성과에 미치는 영향을 분석하기 위하여 실시되었다. 연구의 자료수집 기간은 2015년 12월 11일부터 12월 31일까지이며, 연구 대상자는 3개의 종합병원에 근무하는 간호사 190명을 대상으로 하였다. 통계는 SPSS 21.0을 이용하여 빈도분석, t-test, ANOVA, Scheffe test, Pearson correlation coefficients, Multiple regression analysis를 사용하였다. 간호업무성과에 미치는 영향요인을 분석한 결과 자아탄력성, 결혼상태, 간호근무환경이 영향요인으로 나타났고 전체 설명력은 43%이다. 결론적으로 임상간호사의 근무환경의 개선과 높은 자아탄력성은 간호업무성과 증진에 중요한 요인으로 판단된다. 자아탄력성의 인지와 함양은 경험적으로 학습될 수 있으나 전문적인 자아탄력성 증진 프로그램을 통해 교육된다면 그 효과를 극대화 할 수 있을 것으로 사료된다. 이와 더불어 간호근무환경의 개선을 위해서는 보다 체계적이며 실무에 도움이 되는 기관의 지원이 중요하며 간호업무성과 향상을 위해서는 간호근무환경의 개선 및 자아탄력성 증진이 필수적인 것으로 사료된다. The purpose of this study was to identify the effects of nursing work environment, emotional labor and ego-resilience on nursing performance among clinical nurses. The study design was the cross-sectional survey. The study was conducted from December 11th to December 31st, 2015. The study participants were a total of 190 clinical nurses who were registered in three general hospitals. The data were analyzed by frequency, t-test, ANOVA, Scheffe’s test, Pearson’s correlation coefficients, and the multiple regression analysis using SPSS 21.0 software. These findings indicate that the factors affecting the nursing performance were ego-resilience, marital status, and the nursing work environment, explaining 43% of the variance in the regression model. Based on the results of the findings, it can be concluded that not only the ego-resilience but also the improvement of the nursing work environment are essential factors to enhance the nursing performance. Even though the ego-resilience could be built and recognized by oneself, but that can be enhanced through the ego-resilience improvement program. In addition, more systematic and supports of nursing departments are needed in order to improve nursing work environment. Therefore, it is vital to consider both the enhancement of the ego-resilience and the improvement of the nursing work environment to improve nursing performance.

The aim of this study is to examine the patterns of expressing contemporary beauty from the perspective of Laotzu’s philosophy in order to suggest its concept and characteristics and to suggest specific cases through cosmetics advertisement. In doing so, the study attempted to understand that contemporary beauty is more humanistic and liberal in terms of expression patterns than in any other time period. The research results are as below. The frame concept of Laotzu’s philosophy includes 1. Naturalness, 2. coexistence in Conflict, and 3. Non-otherness. The characteristics of contemporary beauty are natural and healthy, People can foresee changing beauty by the cycle of life and, by admitting this philosophy, people can understand one``s individuality and discover self-esteemed beauty. Also, the results from the cases of cosmetics advertisement are as below: 1. Naturalness was remarkable. Such phenomenon was common in representative brands of the research subjects. Expression pattern was based on soft, natural make-up and hair style. 2. For conflict and coexistence, they introduced the ancient image of the situation, and the situational image using food and herbs demonstrated a functional, situational image, which was used for the cosmetics advertisement based on the mutual coexistence concept instead of dichotomy of period or material. 3. Non-otherness advertisement, of which there was none, we expected that maximized marketing effect would be achieved if non-otherness cosmetics advertisement expressed the contemporary beauty because itcould solicit sympathy form many consumers.
