The need and interest for a successful operation of Information System in the defense industry have increased due to a rapid development in ICT. However, research on adderssing such increased demand has been minimal. This paper introduces a Success Model for IS in the defense field based on literature reviews, and proves the performance of the proposed model. The verification results show that the quality factors of IS have positive influence on perceived usefulness and user satisfaction. The results, as well, imply that perceived usefulness and user satisfaction improves the operational performance of IS. Therefore, this study proves that quality factors of IS increase the operational performance through perceived usefulness and user satisfaction. Through this research, the patterns of information utilization in the defense IS is understood, and the directions for improving the operational performance of IS is presented.

점령기에 관한 수많은 연구성과에도 불구하고, 점령 문제를 어떻게 인식할 것인가에 관한 논의가 충분히 진전된 것 같지 않다. 이 글은 지금까지 축적된 점령연구들이 주로 일국적인 또는 양자적(bilateral)인 관점에서 서술되어 왔다고 보고, 동아시아와 소수자라는 두 방향을 제안한다. 이 글은 식민지시기에 이루어진 미국의 동아시아 개입과 전후 구상에서 탈식민화의 부재 현상이 남한점령과 일본점령의 차이를 설명한다고 본다. 오키나와와 남한의 점령을 함께 고려했을 때, 점령은 전쟁 점령 부흥이라는 시계열적인 사건으로 이해되지 않으며, 현재에도 작동하는 중층적인 구조로 이해할 수 있다.

This study aims to investigate how health belief of adult female users of the health training center affect health-promoting behavior through self-efficacy and exercise satisfaction. The proposed model is based on health belief model of Rosenstock et al. To validate the proposed model, PLS analysis is performed with the valid 177 questionnaires collected from Seoul and nearby cities. The results are as follows. First, perceived severity has a positive effect on self-efficacy, not on exercise satisfaction. Second, perceived susceptibility does not has a positive effect on both self-efficacy and exercise satisfaction. Third, perceived barriers has a positive effect on self-efficacy, not on exercise satisfaction. Fourth, perceived susceptibility has a positive effect on both self-efficacy and exercise satisfaction. Fifth, self-efficacy has a positive effect on exercise satisfaction and health-promoting behavior. Sixth, exercise satisfaction has a positive effect on health promoting behavior.

The climate problem is both an environmental-social problem and a global problem. The climate justice movement is a social movement that tries to solve environmental and social problems on a global scale. Therefore, the issue of “systemic change” that the climate justice movement represents, or social movements for transition, needs to combine environmental-social transformation with transition on a global scale, or clarify the relationship between the two. This article examines the climate justice movement in the context of the historical evolution of environmental and global justice movements to rethink the goals of climate justice and regime change that it calls for. The historical experience of the environmental justice movement shows that analyzing and responding to changes in the global economic structure and political power is essential to solving environmental problems, while the experience of the global justice movement shows the need for a global public space and the difficulty of realizing democracy and leadership. By enriching the historical sources and contexts of climate justice movements, the scope and direction of climate justice and regime change will become clearer.

Purpose: Outcomes in patients with ovarian high-grade serous carcinoma (HGSC) treated with neoadjuvant chemotherapy(NAC) have been widely studied; however, there is limited information on responses to chemotherapy among patients with non-HGSC. The aim of this study was to compare the survival outcomes of patients with advanced-stage non-HGSC and HGSC treatedwith NAC. Materials and Methods: This study was a retrospective analysis of patients with advanced-stage ovarian cancer treated at YonseiCancer Hospital between 2006 and 2017. The demographics, chemotherapy response, and survival rates were compared betweenpatients with non-HGSC and those with HGSC. Results: Among 220 patients who underwent NAC, 25 (11.4%) patients had non-HGSC histologic subtypes, and all received ataxane-platinum combination regimen for NAC. Patients with non-HGSC had lower baseline cancer antigen-125 levels (p<0.001),poorer response rates (p<0.001), lower rates of optimal cytoreduction (p=0.003), and poorer progression-free survival (PFS) (medianPFS 10.3 months vs. 18.3 months; p=0.009) and overall survival (OS) (median OS 25.5 months vs. 60.6 months; p<0.001),compared to those with HGSC. In multivariate analysis, non-HGSC was a negative prognostic factor for both PFS [hazard ratio(HR), 3.19; 95% confidence interval (CI), 1.73–5.88] and OS (HR, 4.22; 95% CI, 2.07–8.58). Conclusion: In this study, poorer survival outcomes were observed in patients who underwent NAC for treatment of non-HGSCversus those treated for HGSC. Different treatment strategies are urgently required to improve survival outcomes for patients withnon-HGSC undergoing NAC.
