As formal crisis responders, police are trained in de-escalation tactics that are expected to mitigate intimate partner violence and promote survivor safety. However, the alignment between expected and actual practice of police intervention varies, especially when the survivor does not initiate the call, police treat the survivor poorly, or provide an undesirable arrest outcome. At best, unsuccessful interventions do not change survivors’ risk level, and at worse, elevate their risk of experiencing harm. The purpose of this qualitative study was to explore survivors’ perspectives on the process of police intervention, specifically how variations in initiation, quality of engagement, and arrest influence survivors’ safety. Twenty-four women whose partners were in a relationship violence intervention program were recruited to participate in the study. Results showed that many survivors described a range of ongoing, strategic violence perpetrated by their partners that required intervention; yet the complex nature of the violence often extended beyond police capacity. Either survivors called the police, or they were initiated externally by neighbors or strangers; some survivors had dual initiations. Whether survivors reported that police used safety practices during the intervention was related to who initiated the police. Arrests of abusive partners were inconsistent, and they varied based on number of previous calls to the police and visible signs of injury. Survivors of color, specifically Black women, self-initiated at higher rates, experienced fewer safety strategies used by police, and had fewer arrests. No matter the outcomes of police intervention, survivors actively engaged in strategies outside of formal systems to protect themselves and their families. Study results imply that police intervention may be ill-suited to support survivors’ safety goals and highlight a need for alternative interventions focused on de-escalation and prevention.

Banda Aceh region has a coastal environment and frequent earthquakes. The 2004 Sumatra tsunami caused many buildings to collapse and became submerged by seawater in the region. Thus, the buildings might become susceptible to corrosion, which will reduce their strength. Consequently, sudden failure might happen when even a small earthquake occurs. This study reports a corrosion risk assessment for some reinforced concrete (RC) public buildings in Banda Aceh region in order to understand how the tsunami has influenced the corrosion risk level. The assessment was performed by using half-cell potential mapping technique. Six buildings were chosen: three existing buildings, two newly constructed buildings in the tsunami-affected area and one building located outside that area. The assessments were carried out from 2009 until mid of 2010. The assessment results indicated that the corrosion risk to the existing buildings were at intermediate to severe level. In addition, newly developed buildings were at intermediate level, while outside building was still at low levels. Those findings showed that the RC buildings around the tsunami-affected area, either existing or new buildings, had become corrosive. Therefore, it is important to conduct regular corrosion assessments to prevent early failure due to the coexistence of rebar corrosion and earthquake.

The quality of software production is considered important when testing which is involves several IT Staff such as IT development, operation, end-user. One of the issue was having today is a bug processing where it almost all platforms too difficult to avoid from the bugs and even might be full of the risks. In the main of Our focus is on how to measure and attempt to reduce the number were indicated as bugs from low up to critical levels. Furthermore, we were propose with a method already known as a fuzzy logic approach to measure the severity of the presence of bugs during the testing process. there are 20 thousand even more bugs have been reported and be supposed removed with the fuzzy logic approach with various levels. As The end result is that we have found a gradual 20% reduction in various criteria in the testing process as experimentally. Therefore, fuzzy logic is considered as  effective enough to be able to improve existing methods and support to reduce bugs significantly.

Type 2 diabetes mellitus and cardiovascular diseases are two of the most serious health problems produce wide negative impacts in Indonesia. Both diseases shares similar risks factors and may affect individual’s health status and quality of work (QoWL). Unfortunately, there is no evidence reported the chronic diseases risk level and their correlation with QoWL among university staffs in Indonesia. This correlational study aimed to identify the risk level of Type 2 diabetes mellitus (T2DM) and cardiovascular diseases and it correlation with the QoWL among university staffs. As many as 125 university staffs from one of public university in West Java – Indonesia were recruited randomly and asked to complete Finnish Diabetes Risk-Assessment form, The Jakarta Cardiovascular Scale, and quality of work life (QoWL) Evaluation Scale. The collected data were analyzed using descriptive and Pearson Correlation test. Results showed that nearly half of respondents had chronic diseases risk elevation; T2DM (40.39) and cardiovascular diseases (49%). Additionally, more than half of them (52.40%) perceived that their QoWL was less satisfied. It was found there was a significant relationship between T2DM risk level and cardiovascular diseases risk (r = 0.513; p=0.00); however, there was no significant correlation, neither between T2DM risk level (p=0.54) nore cardiovascular disease risk level (p = 0.19) with QoWL. To summarize, the university staffs are vulnerable for developing chronic diseases and have less satisfied QoWL. Therefore, it is important for the university to develop policy or program that enhances the employees’ opportunity in managing the risk and improving their health status and QoWL.

<p>Bridges are subject to extreme corrosion attack due to the surrounding conditions. Chlorides in a maritime atmosphere, de-icing salts or Sulphur Dioxide in an industrial atmosphere cause high corrosion rates if mild steel is left unprotected.</p> <p>The paper shows the best corrosion protection for a long service life under all these conditions offered by a duplex-coating combining a thermally sprayed zinc-based layer with a fitting top-coat. It introduces the thermal spraying process and ist application on bridges, which can be performed in the plant or at the worksite, du r ing erection and for repair work.</p> <p>Thermal Spraying is a well-established process which has been in existence for more than a hundred years. It is used manually, semi-automated and fully automated. Thermal Spraying with zinc and zinc-alloys is a "cold" process having no influence on the microstructure of the coated steel. It refers to worldwide standards and norms, which assure the highest quality of material, work and coatings.</p> <p>Worldwide references on steel bridges are presented as well as the latest developments in research. Throughout this abstract, the results of an intensive study over a service life of more than 26 years of duplex systems for Offshore Wind Energy plants is shown.</p> <p>In conclusion, the presentation also offers a quick view to the application of thermal spraying on concrete bridge structures to protect the rebar by cathodic protection.</p>
