Objective : The purpose of this study was to examine the effects of depressive symptoms on the relationship between avoidance(brooding, reflection, and behavioral avoidance) and sleep quality. Methods : In total, there were 947 subjects who were assessed using self-reports on three measures: Center for Epidemiological Studies-Depression (CES-D), Ruminative Response Style (RRS), Cognitive-Behavioral Avoidance Scale (CBAS), and Pittsburgh Sleep Quality Assessment (PSQI). Results : First, depressive symptoms fully mediated the relationship between brooding and sleep quality. Second, reflection did not mediate the relationship between brooding and sleep quality, and reflection had no direct effects on depressive symptoms. Third, depressive symptoms partially mediated the relationship between behavioral avoidance and sleep quality. Conclusion : This study was confirmed the pathological characteristics of brooding compare to reflection, and the essential role of behavioral avoidance and depressive symptoms on sleep problems.

Chlorine dioxide ($ClO_2$) can be used as a fumigant to kill insects. However, some insects can exhibit an evasive behavior from chlorine dioxide. This evasive behavior decreases the efficiency of the insecticidal activity of chlorine dioxide. This study tested a hypothesis that heat treatment suppresses the evasive behavior and synergizes the control efficacy of chlorine dioxide. Chlorine dioxide fumigation killed the red flour beetle, Tribolium castaneum, under direct exposure condition to the chemical for 12 h with median lethal concentrations of 383.67 ppm (153.63 - 955.78 ppm: 95% confidence interval) for larvae and 397.75 ppm (354.46 - 446.13 ppm: 95% confidence interval) for adults. However, when they were treated with enough diet flour, they exhibited an evasive behavior by entering the diet, which significantly decreased the control efficacy of the fumigant. To clarify the evasive behavior, the choice test of the adults were performed in Y tube arena. The test adults significantly avoided the diet treated with chlorine dioxide, while the antennatectomized adults lost the avoidance behavior. Heat treatment using $46^{\circ}C$ for 6 h killed only 10% or less of T. castaneum. Interestingly, most adults were observed to come out of the diet under the heat treatment. Chlorine dioxide treatment even at 400 ppm for 6 h did not kill any T. castaneum. However, the combined treatment of chlorine dioxide with the heat treatment for 6 h resulted in 95% mortality. These results indicated that heat treatment suppressed the evasive behavior of T. castaneum and synergized the control efficacy of the chlorine dioxide fumigant.

본 연구에서는 경기도 일대 2곳의 대형 아파트 현장의 외국인 작업자 165부의 유효 설문지를 바탕으로 외국인 작업자들의 습관적 행위, 공격성, 상황회피, 심리불안 요인이 위험행동과 안전사고 위험지수에 미치는 영향 관계를 가설검증을 통해 습관적 행위, 공격성, 상황회피 및 심리불안 요인은 위험행동에 영향을 미치는 것으로 나타났으며, 습관적 행위 요인은 안전사고 위험지수에도 영향을 주는 것으로 나타났다. 하지만 공격성, 상황회피, 심리불안 요인은 안전사고 위험지수에 유의한 영향을 미치지 않는 것으로 나타났다. 그러나 위험작업 행동은 안전사고 위험지수에 유의한 영향을 미치는 것으로 나타나 개인적인 성향과 연관이 있는 습관적 행위, 공격성, 상황회피 및 심리불안의 상태가 위험작업으로 발전할 수 있고, 이러한 위험작업행동은 안전사고로 이어질 수 있는 결과를 알 수 있었다. 따라서 외국인 건설현장 작업자의 증가로 인한 안전사고의 증가 문제는 외국인 작업자 때문이기 보다는 외국인 작업자 개인의 성향에 초점을 둘 필요성이 있다고 판단되며, 각 사업장에 직접 투입된 외국인근로자의 성향분석과 그에 따른 개선방안을 도출하면 사고를 줄일 수 있을 것으로 생각된다.

The touchscreen device is now commonly found in the form of mobile phones, tablet PCs, and other devices. Varied physical and visual experiences can be experienced through touchscreens. This study intended to explore how the physical and visual experiences provided by the touchscreen would affect people through their existing associations of behavior-attitude. Previous studies have found that certain behaviors affect attitudes. In particular, the approach-avoidance behavior has been noted to influence both social and personal attitudes. It was thus deemed necessary to ascertain the approach-avoidance effect exerted by touchscreens on the attitudes of users as the technology is widely used today. Experiment 1 provided an approach-avoidance experience via a touchscreen and demonstrated that touchscreen-based approach-avoidance dragging behavior on the touchscreen can affect a user's preference and purchase intent. It was found that a product that had been approached showed both higher preference and higher purchase intent than a product that had been avoided. Experiment 2 investigated whether a similar effect would occur when only the visual experience of approach-avoidance was provided. The outcome proved that products that had been visually approached had higher scores than products that had been avoided, both in terms of preference and purchase intent. The movement of the arm on the touchscreen (Experiment 1) and the visual perception of the approach-avoidance experience (Experiment 2) were both shown to influence participants' attitudes toward products. The results of this study suggest that the behavior and perception of users may be an important factor in designing touchscreen interfaces for online shopping.

This study was to examine the differences of Korean and Chinese high school students on classroom goal structure(i.e., mastery, performance-approach, and performance-avoidance), help-seeking behavior(i.e., help-seeking, and help-seeking avoidance), and school engagement(i.e., behavioral, cognitive, and emotional), and to identify the mediating role of help-seeking behavior in the links between classroom goal structure and school engagement. The final samples consisted of 290 Korean and 294 Chinese students in high school. Results were as followed. Firstly, Chinese students had a higher classroom mastery goal structure, classroom performance-avoidance goal structure, help-seeking and emotional engagement than Korean students, whereas Korean students had a higher behavioral engagement than Chinese students. Secondly, for Korean students, help-seeking and help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Moreover, for Korean students, help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. While, for Chinese students, help-seeking and help-seeking avoidance mediated between classroom performance-avoidance goal structure and school engagement. Also, for Chinese students, help-seeking avoidance mediated between classroom mastery goal structure and school engagement. Therefore, help-seeking should be promoted in order to improve students' school engagement, and classroom mastery goal structure need to be created in order to encourage students' help-seeking.

Behavioral errors of the seafarers are one of the major causes of collisions and are usually corrected through education and training. To correct this behavioral error, the structure in which the behavioral error occurs needs to be identified and analyzed. For this purpose, behavior observation data were obtained through ship maneuvering simulation for collision encounters. The 9-state behavior classification frame proposed by Reason was used for the behavior observation and 50 university students were involved in the experiment. Behavioral analysis used the behavioral model of collision avoidance success and failure, which was developed from the 9-state Left-to-Right Hidden Markov modeling technique. As a result of the experiment, the difference between behaviors of success and failure of collision avoidance was clearly identified, and the linkage between 9-state behaviors, required to prevent collision, was derived.

Auto-navigation algorithm have been studied to avoid collision and grounding of a ship due to human error. There have been many research on collision avoidance algorithms but they have been validated little on the real coastal traffic situation. In this study, a Collision Avoidance algorithm is developed by using Fuzzy algorithm and the concept of Changeable Action Space Searching (CAS). In the first step, on a basis of collision risk calculated from fuzzy algorithm in the current time(t=to), alternative Action Space for collision avoidance is planned. In the second step, next alternative Action Space for collision avoidance in the future($t=to+{\Delta}t$) is corrected and re-planned with re-evaluated collision risk. In the third step, the safest and most effective course among Action Space is selected by using optimization method in real time. In this paper, the main features of the developed collision avoidance algorithm (CAS) are introduced. CAS is implemented in the ship-handling simulator of MOERI. The performance of CAS is tested on the situation of open sea with 3 traffic ships, whose position is assumed to be informed from AIS. Own-ship is fully autonomously navigated by autopilot including the collision avoidance algorithm, CAS. Experimental results show that own-ship can successfully avoid the collision against traffic ships and the calculated courses from CAS are reasonable.
