Sound radiation from a perforated unbaffled plate

A model to calculate the sound radiation from an unbaffled perforated plate is proposed. This is achieved by modifying an existing model of an unbaffled plate to include the effect of perforation in terms of a continuously distributed surface impedance to represent the holes. Results are compared with those of an idealised situation, a perforated plate in an equally perforated baffle. At low perforation ratios, the radiation efficiency is lower for the unbaffled case but as the perforation ratio increases, the results for both conditions become similar. The effect of perforation increases as the perforation ratio increases and also as the hole diameter reduces. Comparison with existing measurement is also found to give a good agreement

Perceived Ability to Practice in Disaster Management Among Public Health Nurses in Aceh, Indonesia

Background: The increasing number of disaster events around the world has challenged every country to develop better disaster-management strategies. As a part of healthcare system, public health nurses (PHNs) should be involved in caring for people in disasters. Currently, there is no known study whether PHNs of Aceh, Indonesia, working with community people who are at high risk of confronting natural disasters, are able to perform their roles and functions regarding disaster management. Methods: 252 PHNs from twenty-seven public health centers in Aceh were studied during November to December 2010 to evaluate their perceived ability to practice regarding disaster management at each disaster phase: preparedness, response, and recovery phase. The perceived ability to practice was assessed by using the 30-statement, five-point Likert-scale (0-4) of Public Health Nurses' Perceived Ability to Practice Regarding Disaster Management Questionnaire (PHNPP-DMQ). The composite scores of each phase and the total score were calculated and transformed to percentage for ease of presentation across disaster phases.Results: Overall, the PHNs' perceived ability to practice regarding disaster management in Aceh was at a moderate level (M=74.57%, SD=13.27). The highest mean score was for the recovery phase (M=78%), and the lowest mean score was in the preparedness phase (66.15%).Conclusion: The finding of this study evokes challenges to the local government of Aceh province to further prepare PHNs to increase their ability in disaster management

Peran Negara dalam Menciptakan Perdamaian: Kasus Pilkada Langsung di Kab. Gianyar dan Kab. Buleleng, Provinsi Bali

Until recently, Direct Local Election within its implementation have been causing potential for serious conflict in regional level. Moreover, this is always leads to anarchy which triggers national disintegration. The Local Government power manages conflicts in Local Election needed for social stability. This paper will to elaborate the cases of conflicts in Local Election of Gianyar and Buleleng Regencies. However, the intensity resulted from both of regencies is different. Difference on conflict's intensity raised is correlated to the role of government (in this case Local Government and other related institutions) in creating strategies for conflict solution in these regencies. The Government took several non-formal strategies for those parties involved. The non-formal strategies was taken for Gianyar Regency and its illustrated through several non-formal mediations to create peace and to build better communication within the resolution. I conclude that the hard situation in creating peace for conflict resolution in Buleleng was because the formal strategy taken is actually weakening communication between those involved in conflict, thus people use wrong strategies to address their message
