Multi-layer composites consisting of silicon nitride, silicon nitride-silicon carbide and boron nitride-alumina layers were prepared fly stacking the corresponding ceramic tapes. The composites demonstrated self-diagnostic capability and non-catastrophic failure behavior. The composites consisting of many thin layers exhibited high strength and stepwise increase of the electrical resistance during the flexure test. The strength of the composite with too thick silicon nitride layers was low and the electrical resistance was abruptly increased to the detection limit of the digital multi-meter during the test. An extensive crack branching was observed in the weak (BN + Al$_2$O$_3$)layer.

In the interest of nuclear power plant safety, a self-diagnostic monitoring system (SDMS) is needed to monitor defects in safety-related components. An air-operated valve (AOV) is one of the components to be monitored since the failure of its operation could potentially have catastrophic consequences. In this paper, a model of the AOV is developed with the parameters that affect the operational characteristics. The model is useful for both understanding the operation and correlating parameters and defects. Various defects are introduced in the experiments to construct a fault library, which will be used in a pattern recognition approach. Finally, the validity of the fault library is examined.

Necrotizing sialometaplasia is a rare, benign, self-limiting inflammatory process, with most cases occurring in the palatal region. Although the pathophysiology of this condition remains unknown, it has generally been considered an ischemic reaction involving the minor salivary glands. Due to its clinical and histologic similarities to malignant salivary gland tumor, diagnostic biopsy is required. Careful monitoring is also recommended, and clinicians should provide sufficient information for pathologists to ensure the histologic diagnosis.

Purpose: This study was done to develop a web-based diagnostic evaluation program for nurses to prevent malpractice liability. Methods: A comprehensive review of the literature and 9 specialist interviews were used to search for learning goals and content for protection for nurses from malpractice. Data on needs for learning goals were collected from 56 hospital nurses who agreed to complete a self-report questionnaire. The diagnostic program was evaluated between September 2008 and August 2009 by 35 new hospital nurses using an application of the web-based program evaluation tools by Chung (2000). Results: A comprehensive review of the literature and interviews were used to search for learning goals and content. The evaluation program was composed of the 73 questions for diagnostic evaluation under 23 learning goals and 6 grand learning goals which included the principles of law, patient's rights, legal responsibility, patient's safety, regulation on nursing practice and patient's rights protection. Evaluation of the program showed that the mean for program evaluation was 3.43 (SD=.37). Conclusion: This diagnostic evaluation program could be an efficient method for teachers and learners to improve nurses' behavior in protecting the patient's rights and preventing malpractice claims.

Leadership development corresponds to the focus on the individual's success and competitiveness strategy. This is the optimal direction of the organization of attitude development because it covers two aspects of the student's personality development, professionally-oriented and self-centric. The aim of the study is to identify and compare the leadership level in second-and fourth-year students to see dynamics of development and implementation of the leadership phenomenon in the professional and personal making up of future specialists. Based on the theoretical analysis of the issue, the authors developed an objective and subjective diagnostic model for leadership skills. In this study, data of the objective diagnostic technique are the key. Subjective diagnostic technique for leadership skills provides insights for problem interpretation. At the level of the first group of respondents, the average Leadership Skills Level of the second-year students was quite low and was found within the medium level. The second group of respondents consisting of the fourth-year students showed a slight but effective improvement. The Leadership Skills of this group were found at a sufficient level. Positive dynamics was revealed for all criteria of leadership skills as a result of applying objective diagnostic methods: decreased percentage of students with negative and relatively low markers of Leadership Skills Level and corresponding increase in percentage of applicants with positive markers of Leadership Skills Level. Further research can be organized in the direction of identifying and developing successful universal and professionally-oriented tactics for leadership development in students as part of attitude development.

This research explored links between mother/child personality characteristics based on their diagnostic and clinical pathology. The 232 participants, selected from mother-child pairs receiving psychological care in a hospital setting, were tested and interviewed by clinical practitioners. Correlations were found between mothers' Psychopathic Deviate, Paranoia, Psychasthenia, and Schizophrenia and sons' Psychasthenia, aggression, alienation, depression, and anger. Mothers classified with Hysteria were likely to have aggressive children. Mothers with low self-esteem, repression, frustration, and strong levels of extroversion had daughters with anger/rage issues. Sons of mothers diagnosed with Hypochondriasis, Depression, Hysteria, Psychopathic Deviate, Paranoia, and Psychasthenia had high rates of Oppositional Defiant Disorder and ADHD. Children of mothers diagnosed with depression had high rates of ADHD. Specifically, mothers with Hypochondriasis, Hysteria, and Psychopathic Deviate had daughters with high rates of ADHD.

Based on the concept of Industry 4.0, various sensors are attached to facilities and equipment to collect data in real time and diagnose faults using analyzing techniques. Diagnostic technology continuously monitors faults or performance degradation of facilities and equipment in operation and diagnoses abnormal symptoms to ensure safety and availability through maintenance before failure occurs. In this paper, we propose a model to analyze the data and diagnose the state or failure using machine learning. The diagnosis model is based on a support vector machine (SVM)-based diagnosis model and a self-learning one-class SVM-based diagnostic model. In the future, it is expected that this model can be applied to facilities used in the entire industry by applying the actual data to the diagnostic model proposed in this paper, conducting the experiment, and verifying it through the model performance evaluation index.
