The purpose of this study is to examine the effects of self-leadership and self-efficacy on organizational performance, or more specifically, job satisfaction, organizational concentration and organizational citizenship behavior and then the effects of hospital organization members' job attitude on organizational performance, helping strengthen capability that individuals of the members have and ultimately improve that performance. Findings of the study can be summarized as follows. First, self-leadership has statistically significant effects on organizational citizenship behavior. Second, self-leadership has statistically significant influences on self-effectiveness, especially job satisfaction and organizational concentration. Third, how self-efficacy influences organizational effectiveness was examined to find that self-efficacy has significant effects on organizational concentration, but not on job satisfaction. Fourth, self-efficacy has no effect on organizational citizenship behavior. Fifth, how organizational effectiveness influences organizational citizenship behavior was investigated to find that effectiveness has statistically significant effects on organizational concentration, but not on job satisfaction.

Objectives: The purpose of the study is to investigate the relationship between self-efficacy and learning attitude according to smoking experience in the middle school students. Methods: A self-reported questionnaire was completed by 608 middle school students in Gyeongnam from July 1 to 23, 2013. The questionnaire consisted of general characteristics of the subjects, smoking behavior, self-efficacy, and learning attitude. The questionnaire was adapted and modified from Kang, Park, and Koh. The self-efficacy was divided into general efficacy and social efficacy. The learning attitude was divided into attention concentration, learning method, and self learning. Data were analyzed using SPSS Win 21.0 program. Results: The nonsmoking students tended to have higher general efficacy and social efficacy than the smokers (p<0.01). The nonsmokers had more attention concentration in learning attitude than the smokers (p<0.001). The learning method (p<0.001) and self learning (p<0.001) showed the same results between the two groups. The smoking experience had the negative correlation with general efficacy (r=-0.164) and social efficacy(r=-0.154). The general efficacy is positively related to social efficacy (r=0.568). The smoking experience had the negative correlation to attention concentration (r=-0.235), learning method (r=-0.211) and self learning (r=-0.148). The attention concentration was positive relation with learning method (r=0.690) and self learning(r=0.662. The learning method had positive relation to self learning (r=0.764). Conclusions: The smoking students tended to have lower self-efficacy and learning attitude, so it is necessary to implement the smoking prevention program in the middle school students.

This study aims to understand the degree of inequality of surveyed rural amenity resources according to resources and region in basic self governing body by estimating the Gini Coefficient and Lorenz Curve. Case Study was performed in Sunchang basic self governing body which full survey of rural amenity resources was completed. The Gini Coefficient was applied to measure the concentration of amenity resources in 11 Eup-Myun regions, Sunchang county of Jeonbuk province. The results demonstrate significantly different variation according to Eup-Myun regions and amenity variables. This result would be used as a basic data for rational rural planning based on amenity resources through identifying distributional concentration of rural amenity resources in basic self governing body.

In this paper, we present forecasting ozone concentration with decision support system. Since the mechanism of ozone concentration is highly complex, nonlinear, and nonstationary, modeling of ozone prediction system has many problems and results of prediction are not good performance so far. Forecasting ozone concentration with decision support system is acquired to information from human knowledge and experiment data. Fuzzy clustering method uses the acquisition and dynamic polynomial neural network gives us a good performance for ozone prediction with ability of superior data approximation and self-organization.

본 논문은 치과에서 많이 사용되고 있는 silane coupling agent로 표면 처리한 의치상 레진과 자가중합 레진 간의 전단 결합력에 미치는 영향에 대해 알아보고자 하였다. 의치상 레진에 silane coupling agent 농도별 표면 처리 후 자가중합레진을 주입하여 전단결합강도를 측정하였다. Silane coupling agent(MPS)의 농도별 표면 처리에 따른 의치상 레진과 자가중합레진 간의 전단결합강도에서는 Vertex self curing resin에서 5%, 7%에서 유의적으로 높게 나타났고(P<0.05), Kooliner에서는 5%에서 유의적으로 가장 높게 나타났다(P<0.05). 따라서 의치상 레진과 자가중합레진 사이에 MPS 5%를 이용한 표면처리가 전단결합강도에 효과적으로 영향을 미치는 것이라 사료된다.

A self-organizing fuzzy logic controller using a genetic algorithm is described, which controlled the glucose concentration for the enhancement of flavonoid production in a fed-batch cultivation of Scutellaria baicalensis G. plant cells. The substrate feeding strategy in a fed-batch culture was to increase the flavonoid production by using the proposed kinetic model. For the two-stage culture, the substrate feeding strategy consisted of a first period with 28 g/I of glucose to promote cell growth, followed by a second period with 5 g/I of glucose to promote flavonoid production. A simple fuzzy logic controller and the self-organizing fuzzy logic controller using a genetic algorithm was constructed to control the glucose concentration in a fed-batch culture. The designed fuzzy logic controllers were applied to maintain the glucose concentration at given set-points of the two-stage culture in fed-batch cultivation. The experimental results showed that the self-organizing fuzzy logic controller improved the controller\`s performance, compared with that of the simple fuzzy logic controller. The specific production yield and productivity of flavonoids in the two-stage culture were higher than those in the batch culture.

This paper presents a simulation study on two self-learning control systems for a fuzzy prediction model of CO (carbon monoxide) concentration:linear control and fuzzy control. The self-learning control systems are realized by using Widrow-Hoff learning rule which is a basic learning method in neural networks. Simulation results show that the learning efficiency of fuzzy controller is superior to that of linear controller.

본 연구에서는 시설물의 자기정화성능을 확보하기 위하여 이산화티탄 광촉매 용액을 코팅한 모르타르의 자기정화성능을 분석하였다. 광촉매 코팅 용액의 농도(1.5 %와 3.0 %), 초친수강화 용액 적용 유무 및 프라이머 용액의 사용 유무를 실험변수로 고려하였다. 광촉매 농도가 증가할수록 메틸렌블루 수용액의 색상 변화율이 증가하였으며, 이는 광촉매 농도가 증가할수록 자기정화성능이 증가하는 것을 나타낸다. 초친수성 광촉매 용액의 적용은 일반 광촉매 용액에 비해 자기정화성능을 다소 감소시킬 가능성이 있음을 나타낸다. 또한, 프라이머를 사용한 모르타르의 자기정화성능은 프라이머를 사용하지 않은 모르타르의 자기정화성능과 뚜렷한 차이를 나타내지 않는다. 한편, 낮은 농도(1.5 %)로 코팅된 모르타르에 비해 높은 농도(3.0 %)로 코팅된 모르타르 시편 표면의 코팅 균열이 미세하여 상대적으로 큰 광촉매 반응면적을 확보하고 자기정화성능 증가에 유리한 영향을 미친 것으로 판단된다.

Background: In monitoring exposure to environmental smoke (ETS), biomarkers can overcome the subjectivity and inaccuracy of self-reporting measurements, and have the advantage of reflecting ETS exposure in all places. This study aims to evaluate the effectiveness of ETS exposure measurement using biomarkers such as urine cotinine. Methods: This study used the Korea National Health and Nutrition Survey data from 2009 to 2018. A total of 28,574 non-smokers with urine cotinine data were selected for the study. The cotinine concentration and ETS exposure rate using urine cotinine was estimated and then compared with the self-reporting measurements. The degree of agreement among measurements of ETS exposure was confirmed. Results: As a result of measuring ETS exposure with urine cotinine, 23,594 (83.8%) out of 28,574 subjects were classified as to exposure groups. This estimate differs significantly from measurements made by self-reporting. In addition, the average concentration of cotinine in non-smokers has decreased to a 10th level over the past 10 years. Based on the biomarker, the sensitivity of the self-reporting was 8.5%-29.0%, the specificity was 16.4%-19.5%, and the kappa value was 2.0%-5.8%. Conclusion: The findings of our study show that self-reporting measurement does not well reflect the extent to which non-smoker's exposure to smoking materials. Whereas cotinine concentration has decreased significantly over the past 10 years, the ETS exposure rate has not reduced. It strongly suggests the need for intervention in the group of non-smokers exposed to low concentrations of smoke. Therefore, an assessment using biomarkers such as cotinine-based measurement should be made in the Health Plan 2030.
