Fiber metal laminates (FMLs) are layered materials comprised of thin metal sheets and fiber reinforced plastic (FRP). This paper presents the numerical study of the formability enhancement of FMLs composed of an aluminum alloy and self-reinforced polypropylene (SRPP) composite. In this study, a numerical simulation based on finite element (FE) modeling is proposed to evaluate the formability of FMLs using ABAQUS/Explicit. The FE model, which included a single layer of solid and shell elements to model the blank, used discrete layers of the solid element with a contact model and shell elements with a friction based model for the aluminum alloy-composite interface conditions. This method allowed the description of each layer of FMLs and was able to simulate the interaction between the layers. It is noted through this research that the proposed numerical simulation described properly the formability enhancement of the FMLs and the simulation results showed good agreement with experimental results.

Purpose: The present study was conducted to develop the Life Respect Enhancement Program and test its effectiveness on suicide knowledge, suicide intervention skills, self-efficacy in suicide prevention, and gatekeeper behaviors among nursing officers. Methods: The program was developed according to the ADDIE model and finalized after practical need analysis, expert verification, and a preliminary study. The present study used a concurrent embedded mixed-method research design. To compare the effects of the Program and the control group on the outcome variables, a quantitative study was conducted using a nonequivalent control group with a pretest-posttest design. Quantitative data were analyzed using χ²-tests, t-tests, and RM-ANOVA. A qualitative study was conducted using FGI with six members of the experimental group 3 months after intervention completion. Results: In total, 56 nursing officers participated in the 3-month follow-up test. Compared to the control group, the experimental group showed significant improvements in suicide knowledge, suicide intervention skills, and self-efficacy in suicide prevention scores at post-test. The significant group differences in suicide knowledge and suicide intervention skills were maintained at 3 months. The gatekeeper behavior scores of the experimental group were also significantly higher than those of the control group at 3 months. Qualitative analysis of the participants' experiences with the Program yielded two themes and seven sub-themes. Conclusion: The newly developed Life Respect Enhancement Program demonstrates significant effects on suicide knowledge, suicide intervention skills, and gatekeeper behaviors. Thus, this program is recommended to promote suicide prevention competencies among nursing officers in military clinical settings.

The fingerprint image quality relies on the clearness of separated ridges by valleys and the uniformity of the separation. The condition of skin still dominate the overall quality of the fingerprint. However, the identification performance of such system is very sensitive to the quality of the captured fingerprint image. Fingerprint image quality analysis and enhancement are useful in improving the performance of fingerprint identification systems. A fuzzy technique is introduced in this paper for both fingerprint image quality analysis and enhancement. First, the quality analysis is performed by extracting four features from a fingerprint image which are the local clarity score (LCS), global clarity score (GCS), ridge_valley thickness ratio (RVTR), and the Global Contrast Factor (GCF). A fuzzy logic technique that uses Mamdani fuzzy rule model is designed. The fuzzy inference system is able to analyse and determinate the fingerprint image type (oily, dry or neutral) based on the extracted feature values and the fuzzy inference rules. The percentages of the test fuzzy inference system for each type is as follow: For dry fingerprint the percentage is 81.33, for oily the percentage is 54.75, and for neutral the percentage is 68.48. Secondly, a fuzzy morphology is applied to enhance the dry and oily fingerprint images. The fuzzy morphology method improves the quality of a fingerprint image, thus improving the performance of the fingerprint identification system significantly. All experimental work which was done for both quality analysis and image enhancement was done using the DB_ITS_2009 database which is a private database collected by the department of electrical engineering, institute of technology Sepuluh Nopember Surabaya, Indonesia. The performance evaluation was done using the Feature Similarity index (FSIM). Where the FSIM is an image quality assessment (IQA) metric, which uses computational models to measure the image quality consistently with subjective evaluations. The new proposed system outperformed the classical system by 900% for the dry fingerprint images and 14% for the oily fingerprint images.

Coupling of non-linear oscillators have long been an interesting problem for physicists. The coupling phenomena have been frequently observed in Josephson junction series array, which have been used for Josephson voltage standard. Interestingly pronounced self-generation effect has been found during recent development of Josephson arrays for programmable Josephson voltage standard. But the coupling effect between the self-generations is not fully understood yet. We present harmonically approximated analytical solutions for coupled self-generations in the Josephson arrays, i.e., Superconductor-Insulator-Normal metal-Insulator-Superconductor (SINIS) array, externally shunted Superconductor-Insulator-Supercondctor (es-SIS) array, Superconductor-Normal metal-Superconductor (SNS) array. We find that the coupling between the self-generated Josephson oscillations through microwave transmission line plays critical role in microwave property of the Josephson array.

Purpose: This study was attempted to verify the effects of Tai Chi exercise on the depression and self efficacy of the patients with rheumatoid arthritis. Method: It employed a non-equivalent control group pre- and post-test design. The research instruments used in this study were depression and self efficacy. Thirty-two patients in the experimental group carried out 50 minutes of Tai Chi exercise for 12 weeks, and 29 patients in the control group did not. Before and after the experiment, both groups were tested for depression and self efficacy. Collected data were processed using the SPSS/WIN 10.0 program analyzing by the frequency, percentage, $X^2$- test, and t-test. Results: Depression significantly decreased in the experimental group. However the improvement in self efficacy of the rheumatoid arthritis patients was not statistically significant but slight enhancement was. Conclusion: Tai Chi exercise is an effective nursing intervention that can be used for rheumatoid arthritis patients.

Purpose: This study examined the fitness of a path model on the relationship among perceived health status, self-esteem, self-efficacy, and Yangsaeng for elderly women. Methods: The subjects consisted of 633 aged women. Data were collected through self.report questionnaires. The data were analyzed with the SPSS and AMOS programs. Results: Perceived health status, self-esteem, and self-efficacy showed a direct effect on elderly women's Yangsaeng while perceived health status and self-esteem showed an indirect effect on their Yangsaeng. Perceived health status and self-esteem showed a direct effect on elderly women's self-efficacy. The hypothetical path model of elderly women's Yangsaeng was proven correct. Conclusion: These results suggest that elderly women's Yangsaeng can be enhanced by increasing their perceived health status, self-esteem and self-efficacy. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes the enhancement of perceived health status, self-esteem and self-efficacy in order to improve elderly women's Yangsaeng.

'Self-esteem' is defined as 'the lived status of one's individual competence and personal worthiness in dealing with the challenges of Life over Time' and high self-esteem is associated with self-confidence, effectively coping, well-being, and responsibility. The first purpose of this study was to identify the concept of self-esteem and to investigate the relationship with self-esteem and responsible environmental behaviors (REB). According to the results, it was found that 'self-esteem' is considered as one of the influential factors on REB and self-esteem enhancement is essential for the responsible choice and determination of environments. The second purpose was to analyse the level of self-esteem in High School students. The mean scores of merits and demerits for all the students involved (402) were 14.58 and 14.91 respectively. By applying the t-test, the two scores were not so different: thus the mean of self-esteem was found to be at a median level. The number of adove-average, average and below-average levels were 114, 163 and 125 respectively. From now on, the development of strategies to enhance self-esteem is urgently needed.
