As information security(IS) is recognized as a critical success factor for organizational growth, organizations are increasing their investment in adopting and operating strict IS policies and technologies. However, when strict IS technology is adopted, IS-related techno-stress may occur in the employees who apply IS technology to their tasks. This study proposes the effect of IS-related techno-stress formed in individuals on IS policy resistance through IS strain and proves that task-technology fit mitigates the negative effect of techno-stress. Research models and hypotheses were presented through previous studies, and the secured samples were used, and structural equation modeling was applied to verify hypothesis. As a result of the study, it was confirmed that IS-related techno-stress (overload, complexity) affected IS policy resistance through IS strain (anxiety, fatigue), and that task-technology fit moderated the relationship between techno-stress and strain. This study suggests a strategic direction for improving the level of internal IS from the viewpoint of suggesting ways to mitigate the stress of employees that may occur when IS policies and technologies are adopted.

This study examined the influence of job stress and personal resources (hardiness, optimism) of child counselors on their burnout and work engagement. For the study, 171 child counselors were surveyed. The main effects of job stress and personal resources on burnout and engagement were tested using hierarchical multiple regression analysis. The findings of this study were as follows: First, the study showed that both job stress and personal resources were related to burnout and work engagement. Specially, job stress was more closely related to burnout, whereas personal resources were more closely related to work engagement. Second, hardiness as personal resources reduced the level of burnout in child counseling. Third, although job stress negatively affected the level of work engagement, personal resources (hardiness, optimism) were relevant predictors of work engagement. Hardy and optimistic child counselors are less likely to experience burnout, they are more likely to experience vigor, dedication, and absorption on their job. Based on the results of this study, the practical implications for child counselors were discussed.

This study tried to understand the mediating role of stress perception and the moderating role of mindfulness in the process of psychological alienation affecting college students' smartphone addiction tendency. Two hundred seventeen university students from Chungcheongnam-do answered the questionnaire. The research model was analyzed with model 7 of Hayes' PROCESS Macro 4.0. When synthesizing analysis results, feelings of alienation mediate stress responses or directly influence smartphone addiction tendencies. At this time, people with high levels of mindfulness tended to lower their smartphone addiction tendencies by alleviating their stress response compared to those with a low level of mindfulness. The implication of this study is that it revealed the psychological process that causes alienation to induce smartphone addiction tendency through stress responses, and that mindfulness plays a role in alleviating stress response and lowering smartphone addiction tendency. In the future, it is necessary to apply the model of this study to people diagnosed with smartphone addiction.

IPCC 제5차 보고서('14) 및 세계위험보고서('15) 등에서 기후변화에 대한 과학적 근거를 제시하였으며, 상위 위험요소로 '수자원 위기'를 꼽았다. 전 세계적으로 기후변화로 인한 이상 기상현상이 발생하고 있으며, 국내에서도 최근 기후변화에 따른 수문사상의 변화로 극한홍수 및 극한가뭄 등으로 인한 피해가 지속적으로 발생하고 있다. 물 관리에서 기후변화는 가장 큰 리스크 요인이므로 물관리 계획 수립 과정에서 기후변화 영향을 고려한 대책을 수립할 필요가 있다. 기후변화에 대한 댐 취약성 평가 관련 연구가 이루어지고 있으나, 미래 기후변화의 불확실성을 충분히 고려했다고 보기 어렵기 때문에 현업에서 의사결정 도구로 활용하기에는 한계가 있다고 볼 수 있다. 이에 따라 과거 수문자료 및 특정 기후모델에 의존하지 않고 댐 인프라의 취약성을 평가할 수 있는 새로운 방법론이 필요하다고 판단된다. 따라서 본 연구를 통해 기후변화의 불확실성에 대비한 댐 취약성 평가 방법론을 정립하고자 한다. 본 연구에서는 기존에 진행된 IPCC 기후변화 시나리오에 따른 댐 취약성 평가 연구사례 및 한반도의 기후변화 영향 및 수문변화를 조사하였다. 그리고 기후 스트레스 시나리오 기반 취약성 평가 체계 및 방법론을 정립한 뒤, 월 강우량을 4분위로 나누어 각 분위별 강우량과 기온을 변경하여 기후 스트레스 시나리오를 생성하였다. 생성된 기후 스트레스 시나리오와 IPCC 기후변화 시나리오 기반 취약성 평가를 유출 및 저수지 모형을 결합하여 충주댐, 용담댐, 합천댐, 섬진강댐에 실시하였다. 그 결과 기후 스트레스에 따른 유출 취약성 평가는 20분위 수 갈수량을 이용해 연중 보장확률을 나타내는 것이 효율적이며, 온도의 영향보다는 강우의 변동이 댐 이수안전도 취약성 평가에 더 큰 영향을 주는 것을 확인할 수 있었다.

We may have had experience to use meaning of stress once at least. Because various mental and physical frustration, conflict, deprivation, and pressure have been happened around the us while we live our whole life. The stress is always existing at our surroundings as much. Now, most stress measurement method is composed of mental method and physical method. The accuracy of stress grade lacks to the disproportion of subjectivity, objectivity, and a science trait. Therefore, in this paper, we propose the index processing algorithm for a stress relief better, after mixing mental measurement result and physical measurement result.

본 논문에서는 전원회로에 사용되는 주요 부품인 트랜스포머에 대한 주요한 고장모드, 고장메커니즘, 스트레스 인자들을 규정하고 그에 따른 가속열화시험을 실시하여 가장 유효한 스트레스 인자를 도출하고 트랜스포머의 열화가 전원회로에 미치는 영향을 분석에 대한 연구를 진행하였다. 전원회로의 고장분석에서, 트랜스포머의 일시적인 특성변화 또는 고장현상(Bunt, Short, Open 등) 발생으로 인한 전류의 급증, 공진주파수 부조화, Spike 발생 등으로 인한 주변부품 또는 구성회로에 미치는 영향을 정확하게 분석하는 것이 어렵다는 점과 비교적 단순한 구조와 강한 내성으로 뚜렷한 고장모드를 보이지 않는 특징으로 인해 전원회로의 고장원인이 트랜스포머 외의 반도체 소자, 저항, 커패시터 등에 의한 것으로 분석되는 것이 일반적이다. 유효한 스트레스 인자별 가속열화시험을 통한 성능평가에서는 절연저항을 제외한 특성에서는 뚜렷한 변화(열화)를 보이지 않았고, 고온고습에 의한 스트레스에서 가장 절연저항의 급격한 열화를 확인할 수 있었다. 또한 열화 각각의 스트레스 인자에 따라 열화시킨 트랜스포머를 실장하여 평가하는 실증적인 방법을 통해 분석한 결과 트랜스포머의 열화는 스위칭소자를 비롯한 주변부품에 스트레스를 가중시켜 발열로 대변되는 현상을 유발하고 트랜스포머 입출력 양단간의 위상편차는 심화시키는 것으로 나타났으며, 스트레스 인자 중 온습도에 의한 영향이 가장 유효하다는 것으로 확인할 수 있었다.
