This work investigates how domestic or foreign ERP affects the relationship between risks associated ERP implementation and intention to adopt risk-mitigating options. We propose three risks such as ERP vendor risk, economic risk, and security risk should affect positively the intention to adopt the risk-mitigating options. To validate the impact of risks and to examine the difference between domestic and foreign ERP, we collected data from IT managers in small and medium sized logistics companies in South Korea using survey questionnaires. We validate the difference between domestic ERP and foreign ERP using multiple regression analyses. We find that IT managers using domestic ERP are willing to adopt risk-mitigating options for economic and security risk. In contrast, we find that IT managers using foreign ERP are willing to adopt risk-mitigating options for ERP-vendor risk. This work may provide IT managers in logistics industry a practical guideline of choosing either domestic or foreign ERP based on their risk preferences.

The rotation-based transformation (RBT) for privacy preserving data mining is vulnerable to the independent component analysis (ICA) attack. This paper introduces a modified multiple-rotation-based transformation technique for special mining applications, mitigating the ICA attack while maintaining the advantages of the RBT.

Sybil attack has been proved effective in mitigating the P2P botnet, but the impacts of some important parameters were not studied, and no model to estimate the effectiveness was proposed. In this paper, taking Kademlia-based botnets as the example, the model which has the upper and lower bound to estimate the mitigating performance of the Sybil attack is proposed. Through simulation, how three important factors affect the performance of the Sybil attack is analyzed, which is proved consistent with the model. The simulation results not only confirm that for P2P botnets in large scale, the Sybil attack is an effective countermeasure, but also imply that the model can give suggestions for the deployment of Sybil nodes to get the ideal performance in mitigating the P2P botnet.

Objectives This study investigated the mitigating effect of Yukmijihwang-tang on antral gastritis and duodenitis by regulating gastrin release in mice. Methods : The normal group comprised mice with no inflammation; the control group comprised mice with ethanol-induced gastroduodenal inflammation. The sample group included inflammation-induced mice treated with Yukmijihwang-tang. Results Based on morphology and histochemistry findings, many hemorrhagic erosions were observed in the control group, while significantly fewer erosions were seen in the sample group. Immunohistochemistry findings showed that the distributions of gastrin, substance P, HSP70, NF-κB p65, and iNOS were considerably lower in the Yukmijihwang-tang -treated group than in the control group. Conclusions The findings suggest that Yukmijihwang-tang has a potent mitigating effect on antral gastritis and duodenitis in mice.

The rise of antimicrobial resistance (AR) is a major threat to global health. The food animal industry contributes to the increasing occurrence of AR. Multiple factors can affect the occurrence and dissemination of AR in the animal industry, including antibiotic use and farm management. Many studies have focused on how the use of antibiotics in food-producing animals has led to the development of AR. However, a few effective mitigating strategies for AR have been developed in food-producing animals, especially those exposed to the environment. The aim of this review is to summarize potential strategies applicable for mitigating AR at the environment-livestock interface.

The Random Early Detection algorithm is widely used in the queue management mechanism of the router. We find that the parameters of the RED algorithm have a significant influence on the defense performance of the random early detection algorithm and discuss the robust of the algorithm in mitigating Low-rate Denial-of-Service attack in details. Simulation results show that the defense performance can be effectively improved by adjusting the parameters of $Q_{min}$ and $Q_{max}$. Some suggestions are given for mitigating the LDoS attack at the end of this paper.

최근 고속철도 평균 좌석이용률이 98% 수준에 이르면서 고속철도 차량 내 혼잡이 발생하는 문제가 나타났고, 이러한 배경에서 본 연구는 고속철도 차량 내 혼잡도 완화에 따른 고속철도 이용자들의 편익을 추정하기 위하여 이용자들의 지불 용의액을 산정하였다. 진술선호자료에 근간한 조건부 가치측정법과 토빗(Tobit) 모형을 통해 지불 용의액을 추정한 결과, 지불 용의액은 소득 수준 및 혼잡도 수준과 비례하는 것으로 나타났으며, 남성, 특실이용자, 자유석 및 정기권 이용자의 지불 용의액이 높고, 주말 이용자, 주부, 통근목적이나 여가목적 이용자들은 지불 용의액이 낮은 것으로 나타났다. 본 연구에서 산정된 지불 용의액은 철도운영자들의 좌석공급 확대를 위한 노력에 대하여 정부의 지원근거나 사회적 편익을 계량화할 수 있는 근거를 제공하였다는 점에서 의의가 있다고 하겠다.

Objectives : To investigate aggravating and mitigating factors of atopic dermatitis and to utilize the outcome in treatment planning. Methods : The research has a cross-sectional study design. Patients' SCORing Atopic Dermatitis (SCORAD) Index, demographic, physical characteristics, social history, serologic index and skin related instrumental measurements were analyzed with correlation and regression analysis method. Results : 48 patients in total were enrolled in the study. Skin Surface Hydration (SSH) and sex were found to be statistically significant aggravating and mitigating factors. As SSH increased, Total SCORAD (tSCORAD) and Objective SCORAD (oSCORAD) increased as well. As SSH decreased, tSCORAD and oSCORAD decreased as well. Female patient had a higher probability of suffering from severer subjective symptoms than that of male. Age, body mass index (BMI), alcohol consumption and smoking, transepidermal water loss (TEWL), IgE, IL-4, IL-5, IL-6, IFN-γ were found not to be statistically significant. There was no correlation between Subjective SCORAD (sSCORAD) and oSCORAD neither with Eczema Area and Severity Index (EASI). Conclusions : Increasing cutaneous moisture should be included in the treatment plan of atopic dermatitis. More emphasis should be put on alleviating subjective discomforts of female patients than that of male. Establishing separate strategies of managing objective eczema status and subjective discomforts respectively should be considered.

Objectives: This study aimed to investigate life stressors and mitigating factors affecting suicide ideation amongst university students in Korea. Methods: Study participants were recruited online from one of the universities in Seoul. The total of 794 samples were included in the final dataset. First, correlation analyses were performed among life stressors, depression and mitigating factors. Second, factorial analysis was conducted to explore different dimensions of he life stressors experienced by the university students. Finally, we used logistic regression to find out the relationship between university students' sub-stressors or mitigating factors, and suicide ideation. Results: Three sub-stressors were identified - interpersonal relationship stress, academic stress and economic stress. All of these stressors were significantly associated with suicide ideation. However, none of them significantly predicted suicide ideation controlling for depression. All mitigating factors - health related behaviors, social support and leisure activities - were statistically significant and negatively related to depression, yet only social support had a significantly negative association with suicide ideation. Conclusions: In conclusion, Social support is the most important factor which may affect suicide ideation among university students in Korea.
