The purpose of the present study is to examine relationships between disconnection and rejection schema, defense mechanism, and mental health in college students using structural equation modeling. The present study suggested a proposed model in which defense mechanism exerted a full mediating effect on the relation between disconnection and rejection schema and mental health. Goodness of fit tests were used to compare the proposed model against competing models. The subjects consisted of 304 college students. They completed the Young Schema Questionnaire(YSQ-SF), the Defense Style Questionnaire(DSQ), and the Mental Health Scale. The results showed that the second model had a better goodness of fit. Based on these findings, it is suggested that psychological interventions for mental health in college students should consider strategies to use more flexible and more adaptive defense mechanism style.

Unsupervised domain adaptation often gives impressive solutions to handle domain shift of data. Most of current approaches assume that unlabeled target data to train is abundant. This assumption is not always true in practices. To tackle this issue, we propose a general solution to solve the domain gap minimization problem without any target data. Our method consists of two regularization steps. The first step is a pixel regularization by arbitrary style transfer. Recently, some methods bring style transfer algorithms to domain adaptation and domain generalization process. They use style transfer algorithms to remove texture bias in source domain data. We also use style transfer algorithms for removing texture bias, but our method depends on neither domain adaptation nor domain generalization paradigm. The second regularization step is a feature regularization by feature alignment. Adding a feature alignment loss term to the model loss, the model learns domain invariant representation more efficiently. We evaluate our regularization methods from several experiments both on small dataset and large dataset. From the experiments, we show that our model can learn domain invariant representation as much as unsupervised domain adaptation methods.

The purpose of this study is to investigate factors affecting the leadership capacity of middle managers and then evaluate the corresponding effect on the performance of subordinates in Vietnamese economic and defense enterprises. Data for the study was collected from questionnaire survey of 15 economic and defense enterprises, preceded by in-depth interviews with respondents who are subordinates of the departments/divisions of these enterprises. The research used logistic regression estimator to address econometric issues and to improve the accuracy of the regression coefficients. Our results show that the determinants of the leadership capacity of mid-level managers in defense and economic enterprises include: (i) personal qualities and qualities of managerial officials (understanding, courage), fairness, assertiveness and compliance), and leadership behaviors of two leadership styles - (ii) a transforming leadership style (influenced by ideals, inspirations, concerns) subordinates, stimulating intellect) and (iii) transactional leadership style (rewarding, detecting and handling problems for subordinates). Based on these results, our study suggests that middle managers should possess superior knowledge, care more about subordinates, understand the strengths and weaknesses of each subordinate, always be creative, assertive and courageous people as well as have high standards of competency and morality in order to become outstanding leaders in Vietnamese economic and defense enterprises.

Objectives: Shift work is a stressful situation. It is important to know the factors associated with the ability to adapt to a shift work schedule. The aim of the present study was to investigate the association between sleep, as well as personality variables, and the resilience of shift work nurses. Method: Self-report questionnaires were administered to 95 nurses who worked in one national university hospital. Connor-Davidson resilience scale, hospital anxiety and depression scale, morningness-eveningness scale, Pittsburgh sleep quality index, other sleep-related questionnaires, and Korean defense style questionnaires were used. Results: Age, shift work duration, off-day oversleep, depression, anxiety, adaptive defense style, and self-suppressive defense style were significantly associated with resilience (p < 0.05). Multiple regression analysis showed that age (${\beta}=0.34$, p < 0.05), depression (${\beta}=-0.25$, p < 0.05), adaptive defense style (${\beta}=0.45$, p < 0.001), and self-suppressive defense style (${\beta}=-0.19$, p < 0.05) significantly predicted the resilience of shift work nurses. Concerning individual defense mechanisms, resignation (${\beta}=-0.20$, p < 0.05), sublimation (${\beta}=0.19$, p < 0.05), omnipotence (${\beta}=0.19$, p < 0.05), and humor (${\beta}=0.20$, p < 0.05) significantly predicted the resiliency. Conclusion: The findings indicate that a specific defense style and other mechanisms were associated with the resilience of shift work nurses. A future prospective study with more participants could further clarify the relationship between sleep-related variables, as well as personality factors, and resilience of shift work nurses.

This study recognizes that the externalizing problem behaviors of child with disabilities are the result of the social interaction between mother and child, and empirically verifies its systematic causal structure and multidimensional influence relationship. It was attempted to derive practical implications that can help the smooth normalization process of children's families. Therefore, 135 children with disabilities and their mothers selected by convenience sampling were targeted, and in the relationship between maternal overprotective parenting and externalizing behaviors of child, effortful control was used as a mediating variable, and defense style of mothers and children was used as a moderating variable. A Conditional Process Analysis(CPA) that can verify the moderated mediation Effect was performed by establishing a research model. As a result of the analysis, first, the overprotective parenting behavior of mother was statistically significant in both direct and indirect effects in increasing externalizing behaviors of child, and the mediation effect by effortful control was also statistically significant. Second, it was confirmed that the moderated mediation effect of effortful control by the mother's defense style was statistically significant, and the moderated mediation effect of effortful control by the child's defense style was not statistically significant. Based on the above results, assuming the importance of the influence of maternal parenting, a direct strategy for change in maternal overprotective parenting, child's Practical implications of parallel strategies with the tendency toward effective control and suboptimal strategies through the application of mothers' coping strategies were discussed.

The style of war in the $21^{st}$ century became digitalized cooperative union tactic, which relies heavily on the system providing real time information. Critical information is provided during the war from sensing to shooting. Therefore, epochal development in observation, reconnaissance (ISR), commanding (C4I) and precision strike (PGM) are necessary. Application of ubiquitous computing and network technologies in national defense is necessary for carrying out with various types of wars in the $21^{st}$ century. Therefore, the author wants to research core technology sector that can be developed and applied in preparation of ubiquitous national defense era. Also plans for applying recent u-Defense technology to the military sector had been suggested. Particularly, the author have suggested plans for utilizing combined future information technologies such as ad-hoc network, RFID for the logistic supply in construction of u-Defense system. By utilizing these information technologies, combat power and strategic capabilities of the military can be enhanced greatly.

Introduction: The objective of the present study was to investigate the defense style of insomnia patients and to grasp the differences in defense style between primary insomnia patients and insomnia patients with history of major depressive disorder. Methods: Forty three subjects with insomnia (11 subjects with primary insomnia and 32 subjects with major depressive disorder) and 138 control subjects participated in this study. To diagnose insomnia and major depressive disorder, interviews including structured clinical interview for DSM-IV (SCID-IV) were done. To assess the defense style, self-reported Korean version of Defense Style Questionnaire (K-DSQ) were completed by the participants. Results: Compared to normal controls, subjects with insomnia used more acting out (t=3.25, p<0.01), consumption (t=2.66, p<0.01), fantasy (t=3.51, p<0.001), resignation (t=5.42, p<0.001), suppression (t=3.28, p<0.01), projection (t=3.92, p<0.01), splitting (t=4.31, p<0.01), undoing (t=2.66, p<0.01), withdrawal (t=6.72, p<0.001) and isolation (t=3.80, p<0.001), and less omnipotence (t=4.08, p<0.001) and humor (t=3.20, p<0.01). Compared to normal controls, subjects with primary insomnia used more undoing and withdrawal. Compared to subjects with primary insomnia, subjects with insomnia with history of major depressive disorder used more resignation and withdrawal, and less humor. Conclusion: In the current study, there were differences in defenses between primary insomnia patients and insomnia patients with major depressive disorder history. To evaluate the pattern of defenses through the K-DSQ might provide important clues to differentiate these two conditions.

In this paper, we introduce that MAAB style guideline has effects on the codes generated from Simulink models for static and dynamic software testing, when weapon system embedded software design and implementation are performed using the model based method. As showing the effects, MAAB guideline is helpful for defect prevention related with coding rules and run time errors associated with the DAPA weapon system embedded software guide. Thus, we check related items between MAAB and DAPA software reliability testing including static and dynamic analysis. And then we propose the criterion to select proper items from MAAB for DAPA guideline and show how to verify the relationship and the effects on reliability of models in Simulink. In addition, we show the needs for clear logics in conditional block models or statements and simple complexity models for Simulink model based design.
