The purpose of this study was to verify the mediating effect of mentalization in the relationship between insecure adult attachment and resilience. A total of 468 data were collected by requesting a survey to an online research company. The collected data were subjected to descriptive statistics and hierarchical regression analysis using spss 25.0. The Sobel test was conducted to verify the mediating effect of mentalization. The research results are as follows. First, there was a significant correlation between attachment anxiety, attachment avoidance, mentalization, and resilience. Second, the mediating effect of mentalization was found to be significant in the relationship between attachment anxiety and resilience, and a complete mediating effect was found. Third, the mediating effect of mentalization in the relationship between attachment avoidance and resilience was found to be insignificant. Through the results of this study, the relationship between insecure adult attachment and resilience was reconfirmed, and the role of mentalization in the relationship between them was also confirmed.

This study were investigated to the factors affecting smart phone applications to avoid display ads. The results of this study are as follows. First, factor analysis, propensity for advertising intrusion was the result of a single factor. Also showed significant effect advertising intrusion ad avoidance tendency. Second, the smartphone motivation for the use of the results of factor analysis, seven factors were, Entertainment, information acquisition, learning/work use, multimedia use, ease of life, time leverage, respectively. Showed low levels of advertising avoidance learning/working synchronous usability and ease high motivation life. Finally a smart phone for involvement that there is no significant difference in advertising intrusion tendency appeared. High involvement group was obtaining information, entertainment, social relationships, and multimedia use, ease of living, time management motivation significantly higher than the low involvement group. The results of this study it is expected that the smartphone application smartphone users to reduce evasion of advertising practitioners to give answers to create display ads advertising.

We investigate the association between tax strategy and investment efficiency focusing on manager's investment decision. Specifically, we examine the effect of manager's tax avoidance on the firm's investment level. The result show that as the degree of tax avoidance becomes higher firm's over investment increases. This result implies that the available resources generated from firm's tax avoidance induces over investment. Prior researches have been interested in the effects of firm's tax strategy on firm value. However, there is little literatures regarding the effects of firm's tax strategy on management's real investment decisions which provides the important implications about the mechanisms between tax strategy and firm value. In this respect, our research provides a meaningful results which demonstrates the effects of firm's tax strategy on manager's real investment decisions. This will provide useful implications for the investors and government regarding manager's tax avoidance behavior.

On the basis of DCPA(Distance to Closest Point of Approach) and TCPA(Time to CPA), the conventional algorithms for collision avoidances have a drawback that the '72 CORLEGs(International Regulations for Preventing Collisions at Sea, 1972) has not taken into account to prevent collisions between ships. In this paper, the proposed algorithm decides whether the own ship is a give-way vessel or a stand-on vessel by observing the relative bearing of the encountered ship. To determine the ship position and time for collision avoidance, the proposed algorithm utilizes the ellipse model for ship safety domain. The computer simulation is done to represent the process of adversive behavior. Using the proposed method, the past maritime accident is analyzed. The proposed method can be effectively applied to collision avoidance by CORLEGs even when the target ship's navigational lights is invisible in poor weather and/or in the restricted visibility.

This paper proposes an algorithm for autonomous mobile robots to effectively navigate obstacles. In order to detect obstacles infrared sensors and cameras are employed. The infrared sensor is utilized to calculate the distance to obstacles while the captured images from the camera are used to determine the width of obstacles. To compute obstacle width, binary image processing, contour detection, and the minimum area rectangle technique are employed. Using the distance to obstacles and obstacle width, the avoidance angle is calculated, and this angle is incorporated into steering control. The proposed obstacle avoidance algorithm was implemented on an autonomous robot, and experimental results demonstrated a maximum reduction in avoidance time by 8.5 seconds compared to using only infrared sensors when the obstacle width is 30cm.

The purpose of this study was to investigate the effect of social support on suicidal ideation among the elderly at welfare centers through the mediating effect of avoidance coping style. This is a descriptive research survey of 392 elderly people at four elderly welfare centers located in G city. Data were collected from October 21 to November 8, 2019, and analyzed using the IBM SPSS/win 26.0 program by t-test, ANOVA, and the Pearson's correlation coefficient. The mediating effect was analyzed by multiple regression analysis according to Baron and Kenny's 3-step analysis procedure. Social support of the subjects was found to be high with an average score of 5.73±1.23, avoidance coping style with 12.53±3.47 points, and suicidal ideations with 6.21±2.06 points. In the correlation between the variables, suicidal ideations were negatively correlated with social support (r=-.146, p=.004) and avoidance coping style (r=.315, p<.001), and these correlations were statistically significant. There was a positive correlation. The avoidance coping style of the elderly using the welfare centers was found to partially mediate the relationship between social support and suicidal ideation (Z=-.270, p<.001). Therefore, to prevent negative emotions such as suicidal ideations in the elderly, various policies and support programs at the local and government level should be continuously implemented.

The purpose of this study was to explore the effects of intolerance of uncertainty and experiential avoidance on relationship addiction and to investigate the mediating effect of experiential avoidance in the relationship between intolerance of uncertainty and relationship addiction among unmarried adults. For this purpose, an online survey was conducted on unmarried adults aged 20 to 29 who are currently engaged in opposite-sex romantic relationships, and a total of 302 data were used for analysis.. The collected data were analyzed using SPSS 29.0 and PROCESS MACRO v4.2. The main results of this study are as follows. First, intolerance of uncertainty and experiential avoidance had significant effects on relationship addiction. Second, experiential avoidance had a significant mediating effect between intolerance of uncertainty and relationship addiction tendencies. This study identified individual psychological factors that induce relationship addiction. Based on the research results, this study suggests directions for counseling interventions to reduce relationship addiction tendencies and promote healthier relationship patterns among unmarried adults.

2002년 이후 지속되어온 미국의 재정적자가 금융위기 중 확대되면서 미국 국가채무가 2012년에는 GDP를 초과할 것으로 전망된다. 미 의회는 5개월 이상 협상을 지속한 결과 2011년 8월 1일 국가채무 한도 상향조정을 포함한 예산통제법을 통과시켜 국가부도사태는 발발하지 않았다. 이러한 미 의회의 국가채무 한도 상향 조정에도 불구하고, S&P는 지난 8월 3일 미국의 국가신용등급을 AAA에서 AA+로 강등하였으며, 주식시장의 경우도 미국의 재정지출 감축으로 인한 경기회복지연, 신용등급 강등 영향으로 인한 국제금융시장의 위험자산 회피현상으로 급락하였다. 미국 재정지출 감축과 위험자산 회피현상에 따른 우리나라의 국내총생산 감소는 미미할 것으로 분석되지만, 재정긴축 계획으로 향후 5년 동안 미국 경제에 평균 -0.5%정도의 GDP 감소 효과가 있으며, 우리나라 GDP도 평균적으로 -0.02% 정도 감소시킬 것이다. 이에 따라 우리나라 기업들도 미국 재정긴축 및 신용등급 강등으로 인하여 발생할 수 있는 사항들을 다각적으로 분석하여 대처를 할 필요성이 제기되고 있다. 다음은 대외경제정책연구원에서 발표한 "미국 재정긴축 및 신용등급 강등의 효과분석"의 주요 내용을 정리 요약한 것이다.
