Information technology is an effective means for raising firm competitiveness. In fact, what to purchase or how to purchase it must fall under a highly complex decision-making in which many different stakeholders are involved. These stakeholders are often known to take a defensive behavior. That is, instead of working toward a common goal of organizational performance, each individual of these stakeholders tends to act defensively to avoid risks he/she faces or minimize subsequent changes. Despite a frequent occurrence of defensive behavior in the process of IT purchasing, there has been no research about defensiveness in IT purchasing. Our study aims to elicit different types of defensive behavior in IT purchasing situations and to identify causes of these defensive behaviors. To this end, we surveyed IT professionals having much experience in IT purchasing and took a qualitative analysis on their opinions. We found out that there exist 9 different types of defensive behavior in IT purchasing and identified a set of factors causing the defensiveness and a set of their consequences.

This study was designed to investigate the relation between stress coping behavior and social adjustments in late childhood. Total 657 teenagers (238 ten-year-olds, 230 twelve-year-olds, and 189 fourteen-year-olds) and their parents living in Inchon area participated in the study. Each child was evaluated whether they cope either (a) defensively or (b) actively in several stressful domains by completing the Stress Coping Hating Scales (Korean). Their social adjustments were measured in areas like peer relationship, family relationship, and conformity with Social Adjustment Scales (Korean). The final examination scores were used to rate children’s Academic Achievements. Finally Korean version of Achenbach’s Child Behavior Check List were completed by parents. As results, girls were found to use more defensive strategies to cope stress, showed more conformity and withdrawn behaviors and achieved higher scores academically than boys. Generally younger children tended to adjust better socially than older children. As children grew older they used more and more defensive strategies to cope with everyday stress. Also older children showed more withdrawn behavior and aggressive behavior than younger children. As anticipated children who used more defensive coping strategies were reported to have more behavior problems, showed poorer social adjustments and academic achievements. Children who used more active coping strategies, on the other hands, were reported to haute less behavior problems, adjusted better socially and had better academia achievements. Finally children who adjusted better socially and had high academic achievements were reported to have less behavior problems.

This study investigated the relation between participation in bullying, peer relationship and children's social status. We examined the classified types of social status among 700 fifth and sixth grade elementary schools students. The data were obtained by administering a self-reported questionnaire. Differences were identified with participation in bullying behavior, intimacy friendship and peer support as peer relationship. The collected data were subjected to a descriptive and F-test analysis using the SPSS software program. The results conveyed that social status was different according to the gender difference. Rejected boys presented more bully, reinforce, assistant and victim behaviors. Neglected boys were more victims of bullying. Defensive behavior was more apparent in popular and neglected boys. Furthermore, such boys had high intimate friendships. Popular boys presented distinctively more peer support. Rejected boys represented less intimate friendship and peer support. On the other hand, popular girls portrayed more defensive behavior. However, rejected girls and neglected girls had less defensive behaviors. Victim behaviors were less coherent in popular and neglected girls. Intimate friendship and peer support were mostly apparent in popular girls. Rejected boys represented less intimate friendship and peer support.

본 연구는 자메이카와 한국과의 통합적 그리고 방어적 인상관리 행동 및 자신을 표현하고자 하는 행동에 있어서의 두 나라간 차이를 연구하였다. 인상관리행동에 관한 선행연구와 문화관련 연구들은 문화에서의 차이점들은 인상관리행동의 스타일을 결정한다고 주장하고 있다. 따라서 본 연구는 자메이카와 한국 문화 중 어떠한 요소들이 구성원들이 좀 더 인상관리 행동을 하는지 그리고 다른 국가 간 문화적 차이를 토대로 어떠한 인상관리행동의 차이를 보이는지 연구하였다. 자메이카와 한국의 102 명 개인을 대상으로 설문 조사한 결과 양 국가에서의 인상관리 행동은 비슷한 점과 다른 점 두 가지를 모두 확인하였다. 비록 본 연구에서는 여러 제한점에도 불구하고, 본 연구의 두 국가 간 문화차이로 인해 조직 내 구성원들의 인상관리전략이 다르다는 것을 확인하였다. 특히 한국은 자메이카보다 좀 더 인상관리를 중요시 여기는 것으로 나타났다. 또한 자메이카는 방어적인 인상관리 행동을 높게 사용하는 반면 한국은 자기프로모션과 통합적 인상관리 전략을 좀 더 많이 사용하는 것으로 나타났다.

Utilization of small robots in psychology and biology provides a new breakthrough in understanding the neurobiological mechanisms of various animal behavior. The expansion of robot use in animal research is partly due to increased availability of economically plausible mobile robots and also due to the current shift in animal research toward more ecologically valid experiments. Ground-breaking experimental findings are expected when the behavioral variables are manipulated in more natural situations. In addition, the results from laboratory could be generalized more easily with added ecological validity. The current paper attempts to review a wide range of applications of animal robots used to study animal behavior and to highlight major advantages and limitations. In particular, this review focuses more on the psychological impact of animal robots than engineering details about their structure and operation. Finally, this review will provide some practical considerations when employing robots in animal experiments.

Sudden intrusion of a large amount of surface water into a flood defensive tunnel or pipeline system can compress the residual air. The compressed air may explode along with water through the inlet or air vent, resulting in hydraulic capacity degradation or safety hazards. This study aims to investigate the behavior of compressed air body in pipelines according to the residual air condition with a series of laboratory experiments measuring pressure variation. It has been found that flow characteristics and residual air conditions have a dominant influence on the magnitude and periodicity of the pressure variation. A proper measure to effectively control the residual air is required for securing the design capacity of flood defensive pipeline systems, since the peak pressure is predominantly affected by residual air conditions.

Purpose: The purpose of this study was to investigate the influencing factors of prevention practices against infection exposure among emergency medical technicians (EMTs) in emergency rooms. Methods: A self-reported questionnaire was filled out by 100 EMTs in emergency rooms from June 1 to August 31, 2017. The questionnaire consisted of items concerning the defensive environment for the prevention of infection exposure, perception of preventive behavior, and degree of performance of preventive actions against infection based on a five-point Likert scale. Data were analyzed by descriptive statistics, ${\chi}^2$ test, ANOVA, Pearson's correlation coefficients, and linear regression. Results: The defensive environment for the prevention of infection exposure was 4.12. The perception of preventive action was 4.71, and the degree of performance of preventive actions against infection was 4.54. There was a significant relationship between the degree of performance of preventive actions against infectious exposures and the degree of perception of preventive behavior(r=.506, p=.01) and prevention of infectious exposure(r=.506, p=.01). The protective environment(B=.360, t=3.236, p=.002) and perceived level (B=.904, t=4.662, p=.000) were influenced by the degree of prevention of infection exposure. Conclusion: It is important to manage the protection environment for infection exposure prevention and to enhance the awareness of infection prevention actions against infection exposure among the EMTs in emergency rooms.
