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.

The threat of North Korea's long-range firepower is recognized as a typical asymmetric threat, and South Korea is prioritizing the development of a Korean-style missile defense system to defend against it. To address this, previous research modeled North Korean long-range artillery attacks as a Markov Decision Process (MDP) and used Approximate Dynamic Programming as an algorithm for missile defense, but due to its limitations, there is an intention to apply deep reinforcement learning techniques that incorporate deep learning. In this paper, we aim to develop a missile defense system algorithm by applying a modified DQN with multi-agent-based deep reinforcement learning techniques. Through this, we have researched to ensure an efficient missile defense system can be implemented considering the style of attacks in recent wars, such as how effectively it can respond to enemy missile attacks, and have proven that the results learned through deep reinforcement learning show superior outcomes.

본 연구는 장애아동의 외현화된 문제행동이 어머니와 아동의 심리사회적 상호작용에 의한 결과물임을 인식하고, 이의 체계적 인과구조와 다차원적 영향관계를 실증적으로 검증함으로써 외현화 행동의 감소를 통한 장애아동 및 장애아동 가족의 순적한 정상화과정(normalization process)에 도움을 줄 수 있는 실천적 함의를 도출하고자 하였다. 이에 편의표집에 의해 선정된 장애아동 및 어머니 135명을 대상으로 어머니의 양육행동과 아동의 외현화 행동 간 관계에서 아동의 의도적 통제를 매개변인으로, 어머니 및 아동의 방어유형을 조절변인으로 하는 연구모형을 설정하고 조절된 매개효과를 검증할 수 있는 조건부 과정분석을 실시하였다. 분석결과 첫째, 어머니의 과보호 양육행동은 아동의 외현화 행동을 증가시키는데 있어 직접적 효과와 간접적 효과 모두 통계적으로 유의하고, 이에 아동의 의도적 통제에 의한 매개효과 역시 통계적으로 유의미함이 확인되었다. 둘째, 어머니의 방어유형에 의한 의도적 통제의 조절된 매개효과는 통계적으로 유의미하고, 아동의 방어유형에 의한 의도적 통제의 조절된 매개효과는 통계적으로 유의하지 않음이 확인되었다. 이상의 결과를 바탕으로, 어머니의 양육행동의 영향에 대한 중요성을 전제로, 부모-아동 상호작용 치료와 긍정적 행동지원 등의 효과적 전략 기틀 위에 과보호 행동변화를 위한 직접적 전략, 아동의 의도적 통제성향과의 병행전략, 어머니의 대처전략 적용을 통한 차선적 전략 등에 대한 실천적 함의를 논의하였다.

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.

Purpose: The purpose of this study is to explore, extract and categorize the team's tactical factors in soccer matches. Tactical factors are extracted on the basis of the phases consisting a football match (attack, defense, attacking transition, and defensive transition). Research design, data, and methodology: A semi-structural interviews were conducted with a group of experts of five football managers and coaches to explore tactical factors. Analysis of the content was done using a categorical aggregation or direct interpretation, and then was conducted factorial extraction and categorization. Results: In the attack phase, a direct attack and a step-by-step (occupation) attack form the type of attack, and in the attack transition phase, a long counter attack and a short counter attack form the type of attack. The type of defense in the defense phase was divided into regional defense and compression defense, and the type of defense in the defense transition phase was divided into defense for delaying counterattacks and defense for immediate pressure. Each tactics appeared differently depending on the situation of the game and the play of style. Conclusions: It may indicate the team's performance and has the potential for being used as a team performance factor. Further implications were discussed.

Purpose : This study attempted to find out the relationship between leadership style, knowledge transfer in nursing officers' job, considering the task characteristics. Methods : The data were collected from the military hospital during November 1st to November 17th, 2008 using a structured questionnaire and analyzed with the statistical method of frequency, correlation, and regression analysis, in SPSS 12.0 program package. Results/Conclusion : The results of empirical analysis shows that the levels of job tension and job focused task domain affect the job characteristics of the nursing officers' organization. The job characteristics have a moderating effect on the relationship between leadership style and knowledge transfer. The research is very useful in finding out the job characteristics which well depict military nursing organizations. This research suggests that a desirable leadership styles affect the knowledge transfer in the job characteristics type.
