  • Remanufacturing re-commercializes a used product to achieve an equal or higher performance level than the original product by disassembling, cleaning, inspecting, repairing, reconditioning, and reassembling the used product. The remanufacturing industry is a key industry necessary to realize carbon neutrality by 2050. This study uses life cycle assessment to analyze the resource reduction and greenhouse gas reduction effects with and without considering the avoided effect for an injector, which is an automobile part that is actively being remanufactured. The results of this study showed that the resource reduction effect and greenhouse gas reduction effect induced by injector remanufacturing were reduced by 95.30% and 93.88%, respectively, based on one unit without considering the avoided effect. However, when considering the avoided effect, which in this case is the environmental impact of not disposing of the used injector and not having to use natural resources to manufacture a new injector because the used injector was reused during remanufacturing, the resource reduction effect and greenhouse gas reduction effect were 190.91% and 188.33%, respectively. The results of this study are expected to be used in the future to evaluate the amount of environmental impact reduction while considering the avoided effect during remanufacturing and to help develop research methodology for remanufacturing.

  • The demand for the study about the pollution haven activities under increasing return to scale is increasing since the trade theory under increasing return to scale has been developed. In this paper, based on Davis (1998)'s argument about home market effect, pollution haven activities under increasing return to scale is developed. The result shows that pollution haven effect can be identified with the high trade barriers. When the trade barriers are lowered, both pollution haven effect of heavy polluted industries and migration of low polluted industries are mixed together. Even the behavior under pollution haven hypothesis and that of pollution haven effects are co-existed. Therefore, to keep both environmental protection and continuous economic development, the local government of the region with high environment preservation value encourages the productivity increase of the environmental technique.

  • The purpose of this study was to test the effect of socially-perfectionism on depression by mediating ambivalence over emotional expressiveness and experiential avoidance. For this purpose, 201 participants across the country conducted the survey, a measure of MPS, AEQ-K, AAQ-II, CES-D. The descriptive statistics, Pearson correlation, path coefficient were conducted using SPSS 23.0. The indirect effect was examined using bootstrap in PROCESS Macro. The results of the study are as follows. First, all the variables had meaningful positive correlations. Secondly, When socially-perfectionism affects depression, ambivalence over emotional expressiveness, and experiential avoidance were mediated. As a result, the implications and limitations of the study were discussed.

  • 전력시스템에 수요관리나 효율향상프로그램 또는 분산형 전원을 도입하는 경우 전력회사의 측면에서는 수입의 감소와 함께 각종 비용에 대한 절감효과가 동시에 발생을 하며, 이러한 비용절감효과를 회피비용으로 정의하고 있는데 이러한 회피비용 중 최대수요의 감소로 인하여 송배전설비의 투자시점이나 투자비용이 변화하게 되어 발생되는 회피비용을 송배전설비회피비용이라고 정의한다. 지금까지 한계비용이나 현재가치법을 이용한 방법론들이 개발되었으나, 최대수요 예측이나 수요 감소효과의 예측 값에 대한 불확실성을 고려한 방법은 없었다. 이에 논문에서는 미래예측값에 대한 불확실성을 고려할 수 있는 One-Year Deferral방법론을 제안하고 이에 대한 사례분석을 시행하였다.

  • 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.

  • The purpose of this study is to examine the effect of distress tolerance on subjective well-being and the mediating effect of experiential avoidance in the relationship between distress tolerance and subjective well-being. We conducted an online survey a total of 285 normal adults in the nation from October 21 to 24, 2015. The questionnaire was composed of a distress intolerance index, a concise measure of subjective well-being, and acceptance action questionnaire. And questionnaires were distributed and retrived by an online survey company. Collected data has been analyzed by the structural equation modeling. The correlation analysis showed that distress tolerance was positively correlated with subjective well-being, while negatively with experiential avoidance. Also, the verification of mediating effects of experiential avoidance in the relation between distress tolerance and subjective well-being indicated that experiential avoidance partly mediated the relationship at a meaningful level. Additionally, deflection correction bootstrap analysis was used to verify indirect effects and its results revealed that the mediating effect going from distress tolerance to subjective well-being passing through experiential avoidance was statistically significant. That is, distress tolerance not only influences subjective well-being directly but also influences indirectly through experiential avoidance. Finally, significance and limitations of this study were discussed along with the suggestions for further research.

  • This study was conducted to understand the dual mediating effect of advertising intrusiveness and advertising attitude on the relationship between Facebook attitude and advertising avoidance on Facebook advertisements. A survey was conducted on 250 male and female students attending M University located in Daejeon, and the result was analyzed with SPSS PROCESS MACRO. First, the result yielded that there is a significant positive correlation between Facebook attitude and advertising attitude, and there is a significant negative correlation between Facebook attitude and advertising intrusiveness and avoidance. There is a significant positive correlation between advertising intrusiveness and advertising avoidance, and there is a significant negative correlation between advertising intrusiveness and advertising attitude. Advertising attitude and advertising avoidance has a significant negative correlation. Second, a complete dual mediating effect was confirmed by investigating the dual mediating effect of advertising intrusiveness and advertising attitude on the relationship between Facebook attitude and Facebook advertising avoidance. Such results profess about the impact of Facebook attitude on the advertising avoidance on Facebook advertisements that advertising intrusiveness and advertising attitude could mediate the decrease in advertising avoidance.

  • The purpose of the this study was to evaluate the effects of self-Control, avoidance cognitive fusion, concentration and learning attitude with high school students. For this, the group acceptance-commitment therapy programs were administered for 12 sessions on a weekly basis. 10 high school students were assigned to treatment group and 10 were assigned to control group. Both pre- post- follow-up of self-Control, avoidance cognitive fusion, concentration and learning attitude were assessed. The results were as the treatment group reported significantly lower avoid fusion to the control group. In addition, the treatment group reported significantly higher score level of self-Control, concentration and learning attitude compared to control. Results indicate that the treatment group is more capable than the control group, of decreasing avoid fusion, while increasing self-Control, concentration and learning attitude. This results suggest that can be applied effectively. Finally, limitations of the present study and suggestions were discussed.
