This study is a descriptive research to grasp the effects of nursing performance on emotional labor, job stress and resilience in general hospital nurses. Method: I surveyed them using a structured questionnaire for collecting data from Aug. 20, 2019 to Sep. 2, 2019. The collected data were analyzed by the frequency, the percentage, t-test, ANOVA, Scheffe's Test, Pearson's Correlation Coefficient, and Multiple Regression Analysis. Results: The factors affecting nursing performance of the subjects were resilience (β=0.58, p<.001), and current position is head nurse (β=0.21, p<.01), the number of working years at current working place (β=0.18, p<.05). The F statistics for the fit of the estimated regression model was very significant as 30.901(p<.001) and the explanatory power was 42.4%. Conclusion: The results of this study showed that resilience was the most influential factor to nursing performance of general hospital nurses, and the number of working years at current working place was the most influential factor to the performance of head nurses. Therefore, it is necessary to develop practical programs strengthening resilience of nurses for the improvement of nursing performance and to apply strategies on development.

The western flower thrips, Frankliniella occidentalis, infests the hot pepper cultivated in greenhouses and has been considered to be controlled by a natural enemy, Orius laevigatus. However, sporadic outbreaks of the thrips due to fast population growth occasionally need chemical insecticide treatments. This study was designed to develop an optimal integrated pest management (IPM) by using selective insecticides along with a safe re-introduction technique of the natural enemy after the chemical insecticide treatment. First, chemical insecticides were screened to select the high toxic commercial products against F. occidentalis. Five insecticides containing active components (pyriproxyfen+spinetoram, abamectin, spinosad, acetamiprid, and chlorpyrifos) were selected among 17 commercial products. These five selected insecticides gave different toxic properties to the natural enemy, O. laevigatus. Especially, abamectin and spinetoram gave relatively low toxicity to the natural enemy compared to organophosphate or neonicotinoid. Furthermore, the five selected insecticides were assessed in their residual toxicities against O. laevigatus. Organophosphate and neonicotinoid insecticides showed relatively longer residual toxicity compared to abamectin and spinosads. Indeed, abamectin or spinetoram did not give any significant toxicity to O. laevigatus after 3 days post-treatment. These residual effects were further supported by the assessment of the chemical residue analysis of the insecticides using LC-MS/MS. These results suggest an IPM technology: (1) chemical treatment of abamectin or spinetoram against sporadic outbreaks of F. occidentalis infesting hot pepper and (2) re-introduction of O. laevigatus to the crops after 3 days post-treatment to depress the equilibrium density below an economic injury level.

This study was conducted to identify the factors Influencing the burnout of general hospital nurses. Method: The study subjects were 150 nurses in three general hospital. The collected data were analyzed by t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and Multiple regression analysis. Results: The factors affecting the burnout of the subjects, multiple regression analysis results showed that emotional intelligence(β=-.441, p<.001), emotional labor(β=.403, p<.001), current position was more than responsible nurse(β=-.111, p<.018), and health status was healthy(β=-.100, p<.029). In addition, the F statistics for the fitness of the estimated regression model were 35.51(p<.001), which was very significant. The explanatory power was 79.7%. Conclusion: The results of this study showed that emotional intelligence of the general hospital nurse was the most influential factor on burnout, and the higher the position, the better the health status, the lower the emotional labor, the lower the burnout. Therefore, the results of this study suggest that it is necessary to find ways to reduce emotional labor and improve health and emotional intelligence in order to reduce burnout of nurses, and it is considered to be useful as basic data for developing intervention programs to lower burnout.

Recently, the view of value and the national consciousness are expressed in various fields because of a rapid urban expanding, enforcement of local self-government system and tendency of democratization over the whole fields of society. It is difficult to satisfy this tendency of social environment change with only existing data management system. Therefore, we would use GSIS mainly used in facility management to develop the integrated urban management system which is connected the related information to related Agency. As a result, we can expect the efficient development, maintenance-management of urban and much civil affairs. On this study, firstly, we select a study area and present a basic direction of various urban facility management system. secondly, we develop the integrated urban information system with related Agency that combined the various urban facility management. Finally, we intended of its expression. It aims to manage as far as the step which is presented a model of urban integrated management system at the study area

Wheat quality score index was proposed as a new criterion of wheat_quality for evaluation of the laboratory testing value such as milling rate (Xm), flour ash content (Xa), flour protein content (Xp) and sedimentation value (Xs). 1) Wheat quality score index was expressed as follows; Milling score index (MSI) $=2.3X_m-72.4X_a$ Protein score index (PSI) =$5.2X_p+0.9X_{psi}$ Composite quality score index (QSI) =$0.63X_{msi}+0.37X_{psi}$ 2) The samples with the more than 100 of MSI would be the good milliability, and the samples with more than 100 of PSI would be the good bread making properties, while that with less than 100 of PSI be good pastry type properties. Whereas most of the samples with higher value of QSI would be related to the good milliability and good bread making properties. 3) MSI, PSI and QSI were significantly correlated to the each related quality components.

오염물질의 발생원 추정에 관한 연구는 대기오염의 원인이 되는 근본적인 문제를 정량적으로 확인할 수 있으므로 대기질을 종합적으로 관리하고 평가하는데 크게 기여하고 있다. 따라서, 오염원에 대한 기여율을 추정하는 수용모델 (receptor model)이 응용 및 개발되고 있으나 우리나라의 경우 대부분 서울지역과 일부 수도권 이남지역인 수원지역을 중심으로 연구가 집중되고 있을 뿐이며, 수도권 북부지역의 경우 대기오염에 관한 기초조사는 물론이고, 관심조차 낮은 실정에 있다. (중략)

21세기 정보사회를 향한 채비가 차곡차곡 시행되고 있다. 정부는 정보화를 촉진하고 정보통신산업을 육성하기 위한 국가전략사업으로 초고속정보통신기반구축 종합계획을 '95 3월에 확정하는 한편, 중소기업의 정보화를 위해 '정보화촉진기금'을 마련했다. 서비스 개시를 목전에 두고 있는 '공공 응용서비스'는 범국가적인 정보화 추진을 위해 민간부문 정보화에 앞서 공공부문부터 정보화하자는 취지에서 비롯된 것이다. 또한 초고속정보통신사업을 주관하고 있는 정보통신부는 자금난에 허덕이고 있는 중소기업을 위해 '정보화 촉진기금'까지 마련해 두고 있어, 중소기업의 숨통을 틔워주고 있다.
