최근 들어 데이트 폭력의 심각성이 사회적 문제로 부각되고 있으나, 데이트 폭력 유형 가운데 통제행동에 관한 연구는 매우 부족한 실정이다. 본 연구에서는 특권의식과 통제행동 간의 관계를 살펴보고, 특권의식이 통제행동에 미치는 영향에서 사회지배경향성과 사회비교경향성의 매개효과가 있는지 알아보았다. 또한, 성차가 있는 것으로 알려진 사회지배경향성의 경우, 특권의식과 통제행동 간의 관계에서 성별에 따라 매개효과가 다르게 나타나는지를 살펴보았다. 그 결과, 특권의식이 높을수록 사회지배경향성 및 사회비교경향성이 강하며, 통제행동을 더 많이 하는 것으로 나타났다. 더불어, 사회지배경향성 및 사회비교경향성 이 강할수록 통제행동을 더 많이 하였다. 특권의식이 통제행동에 미치는 영향에서 사회지배경향성이 완전 매개역할을 하였다. 또한, 특권의식과 통제행동 간의 관계에서 사회비교경향성의 하위요인 중 하나인 능력비교경향성이 완전매개역할을 하였다. 더불어, 특권의식이 사회지배경향성을 매개로 통제행동에 미치는 영향이 성별에 따라 조절되었다. 즉, 특권의식과 통제행동 간의 관계에서 남성의 경우에는 사회지배경향성의 매개효과가 유의하였으나, 여성의 경우에는 유의하지 않았다. 본 연구의 한계점을 논의하고 후속연구에 대해 제안하였다.

It is fascinated research theme to store electric energy as much as possible and to utilize it at the point of proper time. Especially, the demand for energy storage devices has been increased based on the interest for distributed generation and smartgrid. As the results for a number of researches on it, various types of energy storage devices have been developed. Each devices have its own dynamic characteristics, power capacity, and storage capacity followed by storage mechanism. In this paper, the comparison research for various energy storage devices has been performed based on power capacity, storage capacity, discharging time, lifetime, efficiency, and cost. Application researches of SFES(superconducting flywheel energy storage), characterized as 300kW-100kWh, have been performed also.

Background: Despite advances in radiotherapy, overall survival of glioblastoma multiforme (GBM) patients is still poor. Moreover dosimetrical analyses with these newer treatment methods are insufficient. The current study is aimed to compare intensity modulated radiation therapy (IMRT) linear accelerator (linac) and helical tomotherapy (HT) treatment plans for patients with prognostic aggressive brain tumors. Material and Methods: A total of 20 GBM patient plans were prospectively evaluated in both linac and HT planning systems. Plans are compared with respect to homogenity index, conformity index and organs at risk (OAR) sparing effects of the treatments. Results: Both treatment plans provided good results that can be applied to GBM patients but it was concluded that if the critical organs with relatively lower dose constraints are closer to the target region, HT for radiotherapeutical application could be preferred. Conclusion: Tomotherapy plans were superior to linear accelerator plans from the aspect of OAR sparing with slightly broader low dose ranges over the healthy tissues. In case a clinic has both of these IMRT systems, employment of HT is recommended based on the observed results and future re-irradiation strategies must be considered.

Purpose: To assess the success rates of two step loop electrosurgical excision procedure (LEEP) compared with conventional cold conization procedures for decreasing positive surgical margins. Materials and Methods: This study was conducted on 70 patients who underwent colposcopic evaluation in Zeynep Kamil Women and Children's Health Training and Research Hospital between 2013-2015 with indications of CIN 2/3 or persistent CIN 1 for more than 2 years. The study included age matched groups of patients with similar histopathololical lesions who underwent cold conization (n=40) or LEEP (N=30). Results: Comparison of tissue characteristics between the two groups revealed significantly higher deepest depth and lower volume of tissue removed by the two step LEEP. Ectocervical positivity rate was similar between groups (1/39 versus 0/29, P>0.05), while endocervical surgical margin positivity rate was significantly higher in the cold conization group (9/39 versus 0/29, P<0.05). Surgical margin positive cases were significantly older than the cases with negative margins (P<0.05). Conclusions: Two step LEEP made it easier to reach the squamocolumnar junction in the endocervical region with lower blood loss and applicability in office settings. Our study suggests to use two step approach in cases with high grade and glandular CIN.

Non-thermal plasma has attracted medical researchers, since they showed higher apoptosis rate in cancer cells than normal cells. However, it is hard to conclude general cancer cell specific effect because comparison between normal and cancer cell activities after plasma treatment have not been reported yet. This research proposes a comparison of Dielectric Barrier Discharge (DBD) plasma effect on three normal cells lines and three cancer cells lines. We measured cell number, mitochondria activity (MTS assay) and amount of hydrogen peroxide (H2O2) for three days. The results show that the number of cancer cells decreased more than normal cells following of exposure time. On the other hand, mitochondria activities and amounts of H2O2 increased following of exposure time. In addition, we found that DBD plasma exposure on cell suspension in media and media only illustrated no difference in mitochondria activity, H2O2 quantity, and cell number. Thus, we can confirm higher apoptosis rate in cancer cells which is related to the reactive oxygen species (ROS) generated by DBD plasma. The related molecular mechanisms were investigated further.

The land cover of burned area has changed dramatically since Daxinganling forest fire in Northeastern China during May 6 ? June 4, 1987. This research focused on determining the burn severity and assessment of forest recovery. Burned severity was classified into three levels from June 1987 Landsat TM data acquired just after the fire. A regression model was established between the forest canopy closure from 1999 forest stand map and the NDVI values from June 2000 Landsat ETM+ data. The map of canopy closure was got according to the regression model. And vegetation cover was classified into four types according to forest closure density. The change matrix was built using the classified map of burn severity and vegetation recovery. Then the change conversions of every forest type were analyzed. Results from this research indicate: forest recovery status is well in most of burned scars; and vegetation change detection can be accomplished using postclassification comparison method.

Rainfall data from three different types of rain gauge system have been collected for the summertime rain event at Mokpo in the Korean peninsula. The rain gauge system considered in this paper is composed of three tipping-bucket rain gauges with 0.1, 0.2, and 0.5 mm measuring resolutions, the Optical Rain Gauge (ORG), and the PARSIVEL (PARticle SIze and VELocity). The PARSIVEL rainfall rate has been considered as the reference for comparison since it gave good resolution and performance on this event. Comparison with the PARSIVEL rainfall rate gives the results that the error and temporal variation of rainfall rate are simultaneously reduced with increasing the averaging interval of rainfall rate or decreasing the size of tipping bucket. This suggests that the estimated rainfall rate must be optimized, differently for the type of tipping-bucket rain gages, by minimizing the averaging interval of rainfall rate under the condition satisfying the given performance of rainfall rate.

The Industrial Internet of Things (IIoT) confronts industrial manufactures with economic, ecological, as well as social benefits and challenges, referring to the Triple Bottom Line of sustainability. So far, research has mainly investigated its dimensions in isolation or economic aspects have not been compared with ecological and social perspectives. Further, research misses studies that are devoted to the special characteristics and requirements of Small and Medium-sized Enterprises (SMEs). This study aims to contribute to close this research gap, providing a research context that encompasses all three dimensions of sustainability. The results are based on data obtained from 329 SMEs, 222 in Germany and 107 in China, therefore allowing for a comparison of the concepts "Industrie 4.0" and "Made in China 2025" in the context of SMEs. In general, German SMEs expect a lower impact through "Industrie 4.0", perceiving the concept as more beneficial for larger enterprises. We further find that Chinese SMEs foremost see social benefits. Challenges whilst introducing "Industrie 4.0"by German SMEs as well as several frame conditions are perceived more relevant than for "Made in China 2025", as seen by Chinese SMEs. The paper closes with implications for research and practice based on these findings.
