This study has been conducted to verify the applicability of FT-NIR (Fourier Transform Near Infrared) to prove coidentity between market agrochemical products and registered prescriptions. The spectrum correlations were investigated on 83 registered samples and there market products, 23 products which had same formulation and active ingredients and 68 products which had different active ingredients. In 83 samples/products, the primary differentiated spectrum correlation values were 95.86~100%, which mean that all samples qualified over 95% threshold. In 23 products which had same active ingredients and formulations, correlation values were 29.09~99.83%. 3 products over 99.0% were proved to have same active/inert ingredients and formulations although they're from different manufacturers. The rest products except the 3 items were under 95%. In 68 products had different active ingredients, correlation values varied from 2.00% to 93.70%. Higher correlation is supposed to come from similarity of inert ingredients despite different active ingredients. They can be decided to unqualify under 95% threshold. So applicability of FT-NIR has been verified on qualitative distinction of coidentity between registered market agrochemicals.

This study was conducted to identify the health promotion behavior of patients with pulmonary tuberculosis and examine the factors influencing this behavior. The subjects were 152 outpatients who were treated for pulmonary tuberculosis at the national tuberculosis hospital located in M City. Data were collected from July to September, 2016 and analyzed using the t-test, ANOVA, Duncan's test, Pearson's correlation coefficient, and multiple regression analysis. Health promotion behavior was negatively correlated with physical symptoms, perceived barriers, and depression, but positively correlated with self-efficacy. The most powerful variable influencing health promotion behavior was depression and the model showed an explanatory power of 63.5%. The results of this study suggest that it is necessary to employ a variety of strategies to practice and maintain the health promotion behavior of pulmonary tuberculosis patients to decrease their depression and provide psychological support.

The purposes of this study was to identify relationship among self-efficacy, incivility, career identity and professionalism in nursing students. The subjects were 320 junior and senior nursing students from four colleges in Gyeonggi-do. As a result of the study, the average self-efficacy was 3.90 points, incivility was 2.36 points, career identity was 2.64 points, and nursing professionalism was 3.63points. Professionalism of nursing students was positively correlated self-efficacy, career identity, but nursing professionalism was negatively correlated incivility. The predictors on nursing professionalism were self-efficacy, incivility, career identity and rudeness. These variables have explanatory power of 16.3% on nursing professionalism. Therefore, specific strategies are needed to reduce the rudeness experienced in clinical practice and change in the curriculum to increase the career identity of nursing students.

This paper proposes a hybrid independent component analysis(ICA) of fixed-point(FP) algorithm and robust algorithm. The FP algorithm is applied for improving the analysis speed and performance, and the robust algorithm is applied for preventing performance degradations by means of very small kurtosis and temporal correlations between components. And the adaptive adaptation of temporal correlations has been proposed for solving limits of the conventional robust algorithm dependent on the maximum time delay. The proposed ICA has been applied to the problems for separating the 4-mixed signals of 500 samples and 10-mixed images of $512\times512$pixels, respectively. The experimental results show that the proposed ICA has a characteristics of adaptively adapting the maximum time delay, and has a superior separation performances(speed, rate) to conventional FP-ICA and hybrid ICA of heuristic correlation. Especially, the proposed ICA gives the larger degree of improvement as the problem size increases.

This study was done to identify differences in depression, anxiety, and stress in Korea elders (n=55) and New Zealand elders (n=55). Methods: This study was conducted from January 24th, 2013 to February 10th, 2013. We individually matched Korea elders to New Zealand elders based on age and sex, and assessed a questionnaire regarding depression, anxiety, and stress. Results: The average depress score for the Korea elders (13.67/42) was significantly different to the average for the New Zealand elders (4.70/42). The average anxiety score for the Korea elders (11.42/42) was significantly different to the average score for the New Zealand elders (4.92/42). The average stress score for the Korea elders (13.54/42) was significantly different to the average score for the New Zealand elders (5.40/42). The depression score showed a significant relationship with anxiety and stress. There was significantly positive correlation between anxiety and stress. The study suggests that should be considered in developing nursing intervention to manage depress, anxiety, and stress of the Korea elderly people.

This study is a descriptive research to identify the relationship among violence experience, resilience and job stress of nurses working in emergency department. The subjects of this study were 143 nurses with over one year working in emergency departments of 6 hospitals located in D city and C city and collected data through structured questionnaire. It was from November 6th to November 15th. The degree of violent experience of the subjects was 1.26 ± 1.31 out of 4. The average score of resillience was 2.50 ± 0.55 out of 4. The average score of job stress was 3.62 ± 0.49 out of 5. The result of correlation between violence experience, resilience and job stress, among the sub factors, in the correlation among violence experience and job stress sub factors, verbal violence experience was significantly positively correlated with nursing work(r=.194, p=.010), role conflict stress(r=.158, p=.030), and physical threat experience was positively correlated with nursing work(r=.200, p=.008), role conflict(r=.162, p=.027), and conflict with doctor(r=.145, p=.042). In the correlation between resilience and job stress sub factors, nursing work stress is hardness(r=-.189, p=.012), persistence(r=-.165, p=.025), and optimism (r=-.186, p=.013) and there was a negative correlation with the region. Expertise stress is hardness(r=-.230, p=.003), persistence(r=-.195, p=.010), optimistic(r=-.194, p=.010) and there was a negative correlation. Nurse-treated stress was positively correlated with spirituality(r=.154, p=.033). In the subcategory correlations of resilience and violent experience, the hardness had a negative correlation with the physical threat(r=-.150, p=.037) experience. The persistence was negatively correlated with the experience of physical threats(r=-.138, p=.050). The optimism was negatively correlated with the experience of physical violence(r=-.151, p=.036). As a result, it is necessary to create a safe working environment free from violence and to reinforce training on how to deal with violence in order to reduce the job stress of emergency department nurses. In addition, measures to cope with stress according to age and work experience and programs to increase resilience should be developed and mediated to reduce the job stress of emergency department nurses.
