노주란,최은아 한국디지털정책학회 2018 디지털융복합연구 Vol.16 No.1

The purpose of this study is to investigate the relationship of job stress and job satisfaction according to leisure activity type of nurses. The subjects were from August 1, 2017 to August 15, 2017 for nurses working in general hospitals in B, K city. Data were analyzed by frequency, percentage, mean and standard deviation, t-test, ANOVA, and Pearson’s Correlation coefficient. Job stress was slightly lower than the middle level and job satisfaction was slightly higher than the middle level. Job stress was negative correlated with the number of leisure activities per week in types of leisure activity, and job satisfaction was not related. In conclusion, in order to reduce job stress of nurses, it is necessary to increase the number of leisure activities per week and further study is needed for various nurses in a wide area. 본 연구의 목적은 간호사의 여가활동 유형을 분류하고 실증적 분석을 실시하여 여가활동 유형에 따른 직무스트레스 및 직무만족도의 관계를 규명하기 위한 서술적 조사연구이다. 대상자는 B광역시, K시의 종합병원에 근무 중인 간호사를 대상으로 2017년 8월 1일부터 8월 15일까지 이루어졌다. 자료 분석은 빈도, 백분율, 평균과 표준편차, t-test, ANOVA, 상관관계로 분석하였다. 연구결과 직무스트레스는 중간보다 조금 낮았고 직무만족도는 중간보다 약간 높은 정도로 나타났다. 직무스트레스는 여가활동 유형 중 주당 여가활동 횟수와 음의 상관관계가 있는 것으로 나타났으며 직무만족도는 여가활동 유형과 관계가 없는 것으로 나타났다. 결론적으로 간호사의 직무스트레스를 줄이기 위해서는 주당 여가활동 횟수를 증가시켜주는 방안이 필요하겠고, 광범위한 지역의 다양한 간호사를 대상으로 한 추후 연구가 필요하다.

Comparing Production- and Consumptionbased CO2 Emissions by Economic Growth

노주만,조홍종 한국무역학회 2022 Journal of Korea trade Vol.26 No.8

Purpose – Carbon emission standards are based on the “production-based carbon emissions” generated by the production of goods in the relevant country which were the existing measurement methods. However, can such carbon emissions measurement standards be established international? For example, some of the goods produced in developing countries are produced for the demand of developed countries. The method of measuring carbon emission based on the final demand of a certain country is called “consumption-based carbon emissions.” This study compares productionand consumption-based CO2 emissions according to economic growth in ninety-three countries categorized by income level. Design/methodology – Our empirical model considers the difference between production- and consumption-based CO2 emissions according to economic growth. Also, our model investigated whether the EKC hypothesis in most of the previous studies that had been based on production-based emissions was also established in the consumption-based emission model. Considering the continuous characteristics of CO2, we utilized the generalized method of moments (GMM), specifically a system GMM econometric technique because CO2 in the previous period can affect CO2 in the present period. Findings – Our main findings can be summarized as follows: The results show that for the consumption-based CO2 emissions model, CO2 continuously increases as economic growth increases in the upper-middle income countries. The inverted U-shaped result was found in the case of the production-based model. However, in the lower-income countries, an inverted-U shape in which CO2 emissions decrease at some point as the economy grows in the production-based model does not appear. On the other hand, in the consumption-based model, an inverted U-shaped result was obtained when estimating with system-GMM. Additionally, the proportion of manufacturing, energy imports, and energy consumption had an effect on both the production- and the consumption-based model regardless of the group's CO2 emissions. On the basis of such assessments, policymakers need to consider not only production- but also consumption-based options. Originality/value – Previous studies have mainly focused on production-based CO2 emissions, with most of them revolving around economic growth or the effect of various social and economic factors on CO2 emissions. However, this study considers the relationship with economic growth using consumption-based emissions as a dependent variable by classifying ninety-three countries by income level.

Multilayer Perceptron(MLP), Nonlinear Autoregressive exogenous (NARX) 모형을 이용한 계통한계가격(SMP) 예측

노주만,조홍종 한국자원공학회 2020 한국자원공학회지 Vol.57 No.6

With the introduction of competition in the power generation sector in Korea, determining how much each electricity company should develop and maintain a stable system marginal price (SMP) has become an important issue. In this study, SMP was predicted by comparing the values for each company using a multilayer perceptron (MLP) and nonlinear autoregressive exogenous (NARX) model among artificial neural networks (ANN), and setting electricity demand as an external variable. The Autoregressive Integrated Moving Average (ARIMA) was also compared. Each method predicted 30, 40, and 50 days. In the case of MLP, optimal results were obtained when the number of hidden layer units were 90, 85, and 80, whereas in the case of NARX, optimal results were obtained when the number of hidden layer units were 95, 80, and 70. Overall, the forecast errors were small in the order of ARIMA, MLP, and NARX for all predictions. 우리나라 전력시장 발전부문에 경쟁을 도입함으로써 각발전사들이 얼마나 발전해야 할지는 중요한 문제가 되었고, 안정적인 계통한계가격(System Marginal Price, SMP)유지는 중요한 문제다. 본 연구에서는 인공신경망 중 MLP(Multi-Layer Perceptron), NARX(Nonlinear Autoregressive exogenous)를 이용하여 서로 비교 분석했고 외부변수로 전력수요를 설정하여 SMP를 예측했으며, ARIMA(Autoregressive Integrated Moving Average)와도 비교를 실시했다. 모두 30일, 40일, 50일을 예측해 봤으며 MLP의 경우 은닉층의 개수가 90개, 85개, 80개 였을 때 최적의 결과를 보여준 반면, NARX의 경우 95개, 80개, 70개 였을 때 최적의 결과를 보여주었다. 전반적으로 모든 예측에서 ARIMA, MLP, NARX 순으로 예측 오차가 작게 나타났다.

Purpose: This study was to investigate relationships among health promotion behavior, family resilience, marital communication, and successful aging of the new middle-aged living in rural areas. Methods: Data collection was conducted from May 1 to June 20, 2021, participants were 119 adults aged 50~69 living in rural areas. The data were analyzed using the IBM SPSS/WIN 23.0 program for descriptive statistics, independent t-test, one way ANOVA, Pearson’s correlation coefficient, and multiple regression. Results: As a result, factors influencing successful aging for the new middle-aged were avocation (β=-.27, p=.002.), family resilience (β=.24, p=.045), marital communication (β=.22, p=.023), gender (β=.19, p=.023), and the explanatory power of 31.0%. Conclusion: These results suggest that it is necessary to develop a program to strengthen personal avocation, family resilience, and marital communication.

2P-151 Fabrication of multifunctional microcapsules bearing both hydropilic and hydrophobic components

김진,노주란,김진식,정영수,장석태,박주현 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1

Oil/water microencapsulation by microfluidic systems has been a prominent delivery method to prepare functional microcapsules in the food, cosmetic, and pharmaceutical industries because it is an easy way to control the shape and size of structures and functionalities. We prepared biocompatible and multifunctional microcapsules using the precipitation and ionic crosslinking of pectin in a poor solubility environment and with multivalent cations, respectively. When the aqueous solution (including calcium ions and ethanol) in a sheath flow met the flow of a pectin aqueous solution containing oil droplets, ethanol-gelation and ionic cross-linking occurred, enclosing the inner oil phase droplets by solidified pectin shells. Furthermore, the resulting microcapsules stabilized by pectin shells exhibited multifunctionality using a hydrophobic agent and nanoparticles of a hydrophilic species that were dissolved and dispersed, respectively, in the oil phase

Poly(3-hexylthiophene) Nanoparticles Prepared via a Film Shattering Process and Hybridization with TiO2 for Visible-Light Active Photocatalysis

채정완,배나래찬,노주란,김태형,유필진,신태주,박주현 한국고분자학회 2019 Macromolecular Research Vol.27 No.4

We present a methodology to prepare a hybrid photocatalyst based on conjugated polymer nanoparticles (CPNs) by electrostatically adsorbing TiO2 nanoparticles on the surfaces of the CPNs to achieve synergetic effects of efficient light-harvesting by CPNs and photocatalysis by TiO2 nanoparticles by taking advantages of the energy transfer from the CPNs to TiO2. Positive surface charges on CPNs were introduced by adding a portion of cationic amphiphile during the preparation of CPNs using poly(3-hexylthiophene) and a phospholipid via a phase-separated film shattering process. Then, anionic TiO2 nanoparticles were synthesized and adsorbed on the positively charged surfaces of CPNs by electrostatic attraction. The resulting hybrid nanoparticles showed efficient visible-light active photocatalysis which was confirmed by the degradation of methylene blue with visible-light irradiation.
