Purpose: This study aimed to explore human rights sensitivity and the perception of patients' rights among nursing students. For the study, 253 nursing students from K and D universities located in Daegu and the Gyeongbuk region were asked to participate. Methods: Data were analyzed using IBM SPSS Statistics 20.0; in addition, descriptive statistics, a t-test, and a one-way ANOVA were used. Results: The average human rights sensitivity score was 2.40 out of 5 points. Human rights sensitivity was significantly different in education experiences in regards to human rights after getting into nursing school and in nursing courses, as well as experiences of clinical practice. Among the six episodes that measured human rights sensitivity, nursing students reported the highest score on the right to the pursuit of happiness of older people and the lowest score was reported on the right to privacy. The average score of patients' rights perception was 4.53 out of 5 points. In particular, nursing students considered the right to enjoy human worth/dignity and the right to equality to be the most important of patients' rights. Patients' rights perception, in general, was significantly different depending on the number of family members. Conclusion: It is needed to develop an effective nursing curriculum in order to improve nursing students' human rights sensitivity and foster positive perceptions regarding patients' rights.

Objectives : The objective of this study was to evaluate the correlation between earlobe crease(ELC) and Hypertension(HTN) in the auricular point diagnosis. Methods : 140 patients who were admitted the Jeongeup City Geriatric Hospital were examined for the presence or absence of ELC and HTN. The one examined the ELC of patients and the other examined the presence of hypertension. The presence of right ELC, left ELC, right or left ELC, and right and left ELC were respectively compared with the presence of HTN. Chi-square test was used to analyze the correlation between ELC and HTN. Results : The presence of right ELC was significantly related to presence of HTN(p=0.001). The sensitivity, specificity, and positive and negative predictability of ELC for diagnosis of HTN were 0.755, 0.524, 0.787, and 0.478. The presence of left ELC was significantly related to presence of HTN(p=0.002). The sensitivity, specificity, and positive and negative predictability of ELC for diagnosis of HTN were 0.745, 0.524, 0.785, and 0.468. The presence of right or left ELC was significantly related to presence of HTN(p<0.001). The sensitivity, specificity, and positive and negative predictability of ELC for diagnosis of HTN were 0.806, 0.500, 0.790, and 0.525. The presence of right and left ELCs was significantly related to presence of HTN (p=0.007). The sensitivity, specificity, and positive and negative predictability of ELC for diagnosis of HTN were 0.694, 0.548, 0.782, and 0.434. Conclusions : These results show that the presence of ELC is significantly associated with hypertension.

Sensitivity and specificity are popular measures described by the receiver operating characteristic (ROC) curve. There are also two other measures such as the positive predictive value (PPV) and negative predictive value (NPV); however, the PPV and NPV cannot be represented by the ROC curve. Based on the total operating characteristic (TOC) curve suggested by Pontius and Si (International Journal of Geographical Information Science, 97, 570-583, 2014), explanatory methods are proposed to geometrically describe the PPV and NPV by the TOC curve. It is found that the PPV can be regarded as the slope of the right-angled triangle connecting the origin to a certain point on the TOC curve, while 1 - NPV can be represented as the slope of the right-angled triangle connecting a certain point to the top right corner of the TOC curve. When the neutral zone exists, the PPV and 1-NPV can be described as the slopes of two other right-angled triangles of the TOC curve. Therefore, both the PPV and NPV can be estimated using the TOC curve, whether or not the neutral zone is present.

The methods of sensitivity analysis for linear programming can be classified in two types: sensitivity analysis using an optimal solution, and sensitivity analysis using an approximate optimal solution. As the methods of sensitivity analysis using an optimal solution, there are three sensitivity analysis methods: sensitivity analysis using an optimal basis, positive sensitivity analysis, and optimal partition sensitivity analysis. Since they may provide different characteristic regions under degeneracy, it is not easy to understand and apply the results of the three methods. In this paper, we propose a generalized sensitivity analysis that can integrate the three existing methods of sensitivity analysis. When a right-hand side or a cost coefficient is perturbed, the generalized sensitivity analysis gives different characteristic regions according to the controlling index set that denotes the set of variables allowed to have positive values in optimal solutions to the perturbed problem. We show that the three existing sensitivity analysis methods are special cases of the generalized sensitivity analysis, and present some properties of the generalized sensitivity analysis.

The purpose of this paper is to develop a method of the sensitivity analysis that can be applicable to a degenerate tree solution of the minimum cost flow problem. First, we introduce two types of sensitivity analysis. A sensitivity analysis of Type 1 is the well known method applicable to a spanning tree solution. However, this method have some difficulties in case of being applied to a degenerate tree solution. So we propose a sensitivity analysis of Type 2 that keeps solutions of upper bounds remaining at upper bounds, those of lower bounds at lower bounds, and those of intermediate values at intermediate values. For the cost coefficient, we present a method that the sensitivity analysis of Type 2 is solved by using the method of a sensitivity analysis of Type 1. Besides we also show that the results of sensitivity analysis of Type 2 are union set of those of Type 1 sensitivity analysis. For the right-hand side constant or the capacity, we present a simple method for the sensitivity analysis of Type 2 which uses arcs with intermediate values.

The purpose of this paper is to develop a method of the sensitivity analysis that can be applied to a non-tree solution of the minimum cost flow problem. First, we introduce two types of sensitivity analysis. A sensitivity analysis of Type 1a is the well known method applicable to a tree solution. However this method can not be applied to a non-tree solution. So we propose a sensitivity analysis of Type 2 that keeps solutions of upper bounds at upper bounds, those of lower bounds at lower bounds, and those of intermediate values at intermediate values. For the cost coefficient we present a method that the sensitivity analysis of Type 2 is solved by finding the shortest path. Besides we also show that the results of Type 2 and Type 1 are the same in a spanning tree solution. For the right-hand side constant or the capacity, the sensitivity analysis of Type 2 is solved by a simple calculation using arcs with intermediate values.

In this paper we present a new PID controller design method using IMC design. The PID controller is derived based on the ${\infty}$-norm of sensitivity function to guarantee stability and performance robustness. This new PID controller is suitable for the plant with right half plane zeros or with time delay. The Simulation results show that the new method is superior to Ziegler-Nichols, Morari-Zafiriou, Mattezzoni-Rocco methods in respects in overshoot and settling time.

Objective : The Human Rights constitute one of the basic pillars of every work where persons are involved, such is the case of the occupational therapy field. Methods : In this study we investigate the human rights sensitivity and the advocacy activities of occupational therapists. The differences according to their characteristics, the relationship and the impact of the human rights sensitivity are examined and presented. Making use of online surveys 116 subjects participated in the study. Results : The measured average of human right sensitivity is 69.00 ± 17.67 point, being them distributed according to the following subcategories: to the perception of the situation corresponds 23.25±5.62 points, to the perception of the consequences 22.75±6.54 points and for the perception of the responsibility 23±6.54 points. In all the cases have been taken in account the equal rights, the right to education in disables, the right to pursue the happiness of the elderly, the right of the disables to have personal freedom, the privacy rights and the privacy rights for mental illness people. According to the working area the Human Right sensitiveness is higher in Seoul than in the Gyeongsang province meanwhile the advocacy activities is higher in Seoul and in Gyeonggi province than in Gyeongsang province. Depending of the type of service, general hospitals and rehabilitation/nursing hospitals showed higher human rights sensitivity than other service organizations According to the working field, occupational therapy group focused in elderly showed higher Human Right sensitivity than other fields. Professionals belonging groups of clinical experience from 3 to 5 years and from 6 to 10 years showed higher advocacy activities than professionals with more than 11 years of experience. A positive correlation was showed between the human rights sensitivity and the advocacy activities. For this situation, the human rights sensitiveness was divided in sub-categories in perception of the situation, perception of the consequences and perception of the responsibility. As showed by the result of multiple regression analyses the advocacy activities of human would grow up in accordance with the increase of the human rights sensitiveness of responsibility perception. Conclusion : Due to the actual lack of information, the collection and study of basic data is fundamental for the development of practical human rights educational programs and to emphasize the role of the defense of the human rights.

This paper presents a new method for first and second order eigen-sensitivity analysis of system matrix in augmented form. Eigen-sensitivity analysis provides invaluable informations in power system planning and operation. However, conventional eigen-sensitivity analysis methods, which need all the eigenvalues and eigenvectors, can not be applicable to large scale power systems due to large computer memory and computing time required. In the proposed method, all sensitivity computations for a mode are carried out using the augmented system matrix and its own eigenvalue and right & left eigenvectors. In other words sensitivity analysis for a mode does not need informations on the other eigenvalues and eigenvectors and sparsity technique can be fully utilized. Thus compuations can be done very efficiently with moderate computer memory and computing time even for large power systems. The proposed algorithm is tested for one machine infinite bus system.
