Background and Objectives: An association between chronic stress and cardiovascular diseases has been described, but the underlying mechanisms have not been fully elucidated. We investigate the impact of perceived stress on the left ventricular (LV) and endothelial functions in postmenopausal women. Subjects and Methods: We investigated 64 consecutive postmenopausal women (mean age 56.7±9.7 years) with atypical chest pain and chronic stress. Patients with coronary heart disease were excluded. Global and segmental longitudinal deformation parameters of LV were used as parameters to assess myocardial function and brachial flow-mediated dilatation (FMD) was used to assess the endothelial function, and patients were analyzed by the Symptom Checklist 90 Revised (SCL-90-R) to determine emotional stress. The study partici-pants were divided into two groups, based on global severity index (GSI): ≥50 (group A, n=27) or <50 (group B, n=37). Results: Although there were no significant differences in LV geometry or myocardial performance indices between the groups, global LV strain was significantly reduced in group A compared to group B (-16.6 ±2.7% vs. -19.1±1.9%, p=0.001). There were also significant differ-ences in the value of reactive FMD (6.6±2.2% vs. 9.5±2.9%, p<0.001), and same result was observed for nitroglycerine-induced dilatation (14.6±4.7% vs. 18.0±5.8%, p=0.016). Multivariate linear regression analysis showed that GSI was the only significant attributor to global LV strain (β=0.149, p=0.008) and reactive FMD (β=-0.200, p=0.041). Conclusion: Chronic emotional stress may exert negative effects on the LV and endothelial functions, which may be associated with the severity of stress. This study provides a possible mechanism by which stress is associated with an increased risk of cardiovascular dys-function.

In this paper, we design and implement a contest application that enables artists to participate in contest activities, manpower, and job information using smart-phone, and to share and systematically manage the information. While the competition is very important for the artists, it is not easy for them to search the competition information due to lack of time. Therefore, it is effective to provide them with contest information suitable for their interests and to be more immersed in creative activities by sharing them. The core function is to provide a space where artists can share contests in real time through the contest bulletin board and aims to provide a variety of functions for convenient convenience, such as buying and selling of works by artists and spoon market for purchasing materials and art tools do. 본 논문은 스마트폰을 이용하여 예술인들에게 공모전 활동과 인력, 일자리 정보를 제공하며, 그 정보를 서로 공유하고 체계적으로 관리할 수 있는 공모전 애플리케이션을 설계하고 구현하였다. 예술인들은 공모전 활동이 매우 중요한 반면, 작업에 몰두하여 시간의 부족으로 공모전 정보를 일일이 탐색하기가 쉽지 않은 일이다. 따라서 이들에게 관심분야에 적합한 공모전 정보를 제공하고, 공유함으로써 창작활동에 더욱 몰입할 수 있게 하는 효과가 있다. 핵심기능은 공모전 게시판을 통하여 예술인들이 실시간으로 공모전을 공유할 수 있는 공간을 제공하며, 부수적으로 예술인들의 작품 매매와 재료, 미술공구 구매를 위한 스푼마켓 등 편의를 위한 다양한 기능을 제공하는 것을 목표로 한다.
