Purpose: Usage of leisure-sport social media would lengthen and strengthen the effects of positive event experiences on WOM behavior. This study is to examine the extent to which leisure sport social media use has the moderating potential to enhance the direction of the relationship between post-event emotions and event WOM behavior. Research design, data and methodology: A running event located in a major metropolitan area in the southeastern United States was selected. Participants of the running events completed the survey. Descriptive analysis and correlations between primary variables of interest were conducted. To examine interactions within the context of moderated regression, a hierarchical regression analysis was employed. Results: The results confirmed direct effects of a sense of achievement and event satisfaction on event WOM intention, supporting H 1 and H2. In specific, result revealed that the amount of time spending on social media for running content moderated the effect of a sense of achievement on event WOM intention, supporting H3, however, H4 was rejected. Conclusions: There are managerial implications of these results, particularly which pertain to how organizers may be able to use perceived benefits (i.e., a sense of achievement and satisfaction) and social media to increase positive WOM intention.

The purpose of this study was to examine how life-changes after divorce, individual resources, and interpersonal resources affect post-divorce adjustment. Especially it focuses on gender differences. Data were collected from 114 divorced men and 112 divorced women in their 20s and 30s with the inclusion criteria of 1) having hen divorced for at least 6 months but less than 5 years, and 2) not having remarried after divorce. AH divorced men and women were interviewed with self-report questionnaires. The analysis included frequencies, means, t-test, crosstabs, and hierarchical multiple regression models. The major findings were as follows. 1) Divorced women were better adjusted than divorced men. 2) Fnancial satisfaction and health problems were important factors for both divorced men and women. 3) There were gender differences in the variables that affected post-divorce adjustment. Social support and significant others' attitude toward divorce influenced post-divorce adjustment for divorced men. For divorced women, negative change in financial circumstances, their own attitude toward divorce and divorce initiation found significant. This study showed that there were gender differences in the factors affecting Post)divorce adjustment. The findings of this study suggest that a program for supporting divorced men and women should consider gender differences.

Purpose: This study aimed to investigate the influence of post-traumatic stress on professional quality of life as mediated by cognitive emotion regulation among nurses working in small and medium hospitals who have experienced violence and to develop and test a structural equation model of that professional quality of life. Methods: Participants were 215 nurses who had experienced violence working in medium and small hospitals. They were surveyed using a structured questionnaire. Results: The final model was shown to have good fit with χ² (2.83), GFI (.90), TLI (.90), and CIF (.90). Therefore, the model was selected as the final model, supporting 7 of the 11 hypotheses. Post-traumatic stress, adaptive emotional regulation, and maladaptive emotional regulation had significant impacts on empathy satisfaction (professional quality of life subscale) and empathy fatigue (subscale of professional life quality) among nurses who had experienced violence, and the explanatory power of these variables was 28.7% and 38.6%, respectively. Conclusion: In the development of nursing intervention programs to improve the professional quality of life of nurses who have experienced violence, factors such as post-traumatic stress and cognitive emotion regulation (adaptive and maladaptive) should be considered as they were identified in this study as influencing the professional quality of life of such nurses in medium and small hospitals.

본 논문에서는 해상풍력발전단지의 경제성을 파악하고자 발전단가 측면에서 해상풍력 지지구조물 형식 및 시공 방법에 따른 균등화발전비용(levelized cost of energy, LCOE)의 차이를 분석하고 LCOE의 주요 구성 요소에 따른 민감도 분석을 실시하였다. 연구대상 현장으로 국내 서남해 해상풍력실증단지를 선정하였으며, 설치 기수에 따른 공사비를 분석하였다. LCOE 민감도 분석 결과 설비이용률, 터빈 관련 비용, 가중평균자본비용 그리고 BOS(balance of system) 관련 비용의 순서로 LCOE에 대한 민감도가 높은 것으로 나타났다. 아울러 국내 해상풍력 지지구조물로 주로 적용되었던 포스트파일링(post-piling) 재킷 공법을 기본안으로 선정하여 공사비를 산출한 후, 시공 방법을 프리파일링(pre-piling)으로 변경한 재킷 공법과 트라이포드(tripod) 공법의 초기투자비용을 비교하였다. 그에 따른 LCOE를 분석한 결과, 프리파일링 재킷 공법의 경우 고가의 템플릿이 필요하지만, 강재 소모량이 적고, 설치규모가 대형화할수록 시공 기간이 단축되어 전체 공사비 및 LCOE가 낮아지며 경제성이 향상되는 것을 확인하였다.

Despite that porcine spermatogonial stem cells (pSSCs) have been regarded as a practical tool for preserving eternally genetic backgrounds derived from pigs with high performance in the economic traits or phenotypes of specific human diseases, there were no reports about precise definition of niche conditions promoting proliferation and maintenance of pSSCs. Accordingly, we tried to determine niche conditions supporting proliferation and maintenance of undifferentiated pSSCs for short-term. For these, undifferentiated pSSCs were progressively cultured in different composition of culture medium, seeding density of pSSCs, type of feeder cells and concentration of growth factors, and then total number of and alkaline phosphatase (AP) activity of pSSCs were investigated at post-6 day culture. As the results, the culture of $4{\times}10^5$ pSSCs on mitotically in activated $2{\times}10^5$ STO cells in the mouse embryonic stem cell culture medium (mESCCM) supplemented with 30 ng/ml glial cell line-derived neurotrophic factor (GDNF) was identified as the best niche condition supporting effectively the short-term maintenance of undifferentiated pSSCs. Moreover, the optimized short-term culture system will be a basis for developing long-term culture system of pSSCs in the following researches.

Background: : In 2012, the breast cancer estimate worldwide stood at 1.67 million new cases, these accounting for 25% of all types of cancer diagnosed in women. For 2014, 57,120 new cases are expected, with a risk estimated at 56.1 cases for every 100,000 women. The objective of this study was to analyze the satisfaction regarding the use of external breast prostheses by women undergoing mastectomy. Materials and Methods: This cross-sectional study was conducted with 76 women who used an external breast prosthesis (EBP), registered in the services of the Cuiaba Center for Comprehensive Rehabilitation, Mato Grosso, Brazil, from 2009 to 2012. Data were collected from the records of women who had requested the opening of a process of external breast prosthesis concession. Results: Satisfaction with the EBP was identified in 56.6% of the women. Those satisfied with the EBP reported that its weight was not annoying (p<0.01). Although the women felt body sensations of stitches, pains, pulling, dormancy and phantom limb, they are satisfied with the EBP. The variable related to the displacement of the breast prosthesis during activity of everyday life has demonstrated that even though the women have reported the possibility of displacements, they are satisfied with the EBP. The satisfaction with the use of external breast prosthesis did not affect the sexuality of the women with mastectomy. Conclusions: Learning the specificities of the EBP, taking into consideration the satisfaction of its use, allows the rehabilitation team, by listening to their clientele more attentively, following up this woman throughout her life journey, supporting and guiding the best way of use, with an eye to her personal, emotional and social life, as well as to her self-esteem.

Two-way ranging methods such as TWR and SDS-TWR have been considered for many ranging systems because these methods are useful in the absence of synchronization. To estimate the location of a mobile node, complicated ranging procedures consisting of ranging frames between an anchor node and the mobile node are performed. Supporting multiple mobile nodes such as a few hundreds or thousands and several anchor nodes, the ranging procedures have the fatal disadvantage of processing delay and inefficient traffic bandwidth. On the other hand, the one-way ranging method is simple and fast, but susceptible to network synchronization. In this paper, we propose a method to modify asynchronous ranging equations to establish exact frequency or frequency offset, a method to estimate frequencies or frequency offsets, and a method to establish post-facto synchronization with anchor nodes. The synchronization for a node pair is adapted using instantaneous time information and corresponding difference of distances can be determined. We evaluate the performance of TWR, SDS-TWR and proposed ranging algorithms.
