ANALISIS MITIGASI POTENSI LIKUIFAKSI (STUDI KASUS : PROYEK PEMBANGKIT LISTRIK TENAGA GAS DAN UAP LOMBOK, NUSA TENGGARA BARAT)

Likuifaksi memiliki dampak terhadap pondasi karena dapat mereduksi nilai daya dukung aksial dan lateral yang akibatnya akan menyebabkan kegagalan infrastruktur. Proyek PLTGU Lombok dipilih menjadi daerah studi karena daerah tersebut diprediksi memiliki potensi likuifaksi. Pada area building, sistem pondasi yang direncanakan adalah tiang pancang. Area tersebut memiliki potensi likuifaksi di lapisan tanah kedalaman berkisar antara 2 sampai 30 meter. Penelitian ini membahas juga perubahan konfigurasi pondasi tiang yang digunakan sebelum dan sesudah likuifaksi. Untuk alternatif mitigasi likuifaksi, dianalisis perbaikan tanah dengan menggunakan stone column yang dapat meningkatkan kuat geser tanah. Analisis potensi likuifaksi dilakukan dengan metode tsuchida chart dan NCEER, sedangkan metode analisis daya dukung tiang tunggal menggunakan Software LPILE v5.0 dan analisis untuk menentukan konfigurasi tiang kelompok menggunakan Software GROUP v8.0. Saat kondisi likuifaksi, hasil penelitian menunjukan daya dukung aksial tekan tidak mengalami reduksi dikarenakan ujung tiang tertanam pada lapisan tanah keras sehingga daya dukung aksial tekan telah mencapai kapasitas maksimumnya. Daya dukung aksial tarik mengalami reduksi berkisar 1 hingga 47%. Daya dukung lateral mengalami reduksi berkisar 0 hingga 48%. Pada analisis daya dukung tiang grup, perbedaan jumlah pile yang diperlukan dengan kondisi sebelum dan setelah likuifaksi cukup signifikan. Jumlah tiang yang diperlukan ketika kondisi sebelum likuifaksi adalah 121 tiang dengan panjang tiang 30 m sedangkan jumlah tiang yang diperlukan untuk kondisi setelah terjadi likuifaksi adalah 169 tiang dengan panjang tiang 30 m. Untuk area non building, perbaikan tanah yang cocok pada lokasi studi adalah stone column dengan diameter 0.6 m, spasi 0.7 m, dan pola segitiga.

The Effect of Preoperative Oral Chlorhexidine Rinse on Ventilator Associated Pneumonia and ICU Mortality After Open Heart Surgery

Objective: Ventilator-associated pneumonia (VAP) is the most frequent nosocomial infection in the intensive care unit (ICU). VAP develops 10-20% of patients in 48 hours of mechanical ventilation. In this study, it was aimed to determine the effect of preoperative oral chlorhexidine rinse on VAP and mortality in patients undergoing open cardiac surgery. Methods: 300 patients who were planned to undergo elective open cardiac surgery were included in this study. Patients were prospectively randomized into two groups by a computer software. Group 1: Patients brushing their teeth and then gargling with 0.12% chlorhexidine before bedtime at the last night before surgery and 15 minutes before going to the operating room. Group 2, It consisted of patients only brushing their teeth. Results: VAP was seen in 3 patients (2.12%) in Group 1 and in 12 (8.10%) patients in Group 2 (p<0.02). Duration of intubation was 15±7.40 hours for Group 1 and 23 32.01 for Group 2. These differences were statistically significant (p <0.01). Although duration of ICU stay and hospital stay in Group 1 are shorter than in Group 2 but it was not statistically significant (p>0.05). There was no difference in mortality (p>0.05). Conclusion: Consequently, chlorhexidine gluconate rinse before elective cardiac surgery reduced the VAP rate and duration of intubation but did not change the mortality rate and the length of ICU and hospital stay. On the other hand we think these results would be change in large multicentric studies.

„Stadtwerke werden zu Datendienstleistern“

Der Wandel zum digitalen Versorger steht bei vielen Stadtwerken auf der Agenda. Vor allem „datenbasierte Mehrwertdienste“ sollen dazu beitragen, diesen Umbruch auch zu einem wirtschaftlichen Erfolg zu machen. Eine zentrale Rolle spielt dabei das Messdatenmanagement (MDM), so Peter Schulte-Rentrop, Vertriebsleiter Versorgungswirtschaft der Wilken Software Group mit Sitz in Ulm.

HEIZ- UND NEBENKOSTENABRECHNUNG | Jahrzehntelang war der Markt für die Heiz- und Nebenkostenabrechnung fest in der Hand der drei großen Messdienstleister: Drei von vier Abrechnungen kamen aus ihren Händen, und es sah lange so aus, als würde sich daran nichts ändern. Doch nun kommt Schwung in den Markt. Immer mehr Stadtwerke entdecken die Heiz- und Nebenkostenabrechnung als mögliches neues Geschäftsfeld. Darauf haben auch die Hersteller von Branchensoftware reagiert, wie etwa die Wilken Software Group.

Distributed Frequent Interactive Pattern-Based Complex Software Group Network Stability Measurement

Interactive software can run not only independently but also often collaboratively to perform tasks thus forming a larger group of software networks. Hence the analysis of interactions is essential as a way to measure the stability of the entire software group network, i.e. the interactive patterns and frequency. However, current studies rarely investigate the performance of software as groups but as individuals thus omitting their interactions. Especially, the performance of some traditional measurement algorithms which execute in nondistributed runtime environments is poor. In this paper, we proposed a new software group stability model concentrating on software network level behaviors as a group. An algorithm is proposed to extract key nodes and critical interactive items based on frequent interaction pattern, then the stability of software group can be assessed based on the loss of connectivity caused by removing key nodes and key edges from the network, using the algorithm SG-StaMea. Furthermore, our algorithms can quantify the stability. To validate the efficacy of our model, the Spark and Hadoop platforms have been selected as targets systems. Both experiments and experimental data showed that our algorithms have significantly improved the accuracy of software stability measurement compared to classical algorithm such as Apriori of frequent pattern.

Cliente com enfermidade psiquiátrica crônica: reconstrução sociocognitiva no contexto do processo de cuidado institucional [Chronic psychiatric client: socio-cognitive reconstruction in the institutional care process] [Cliente con enfermedad psiquiátrica crónica: reconstrucción socio-cognitiva en el contexto del proceso de atención institucional]

Objetivo: analisar a reconstrução sociocognitiva dos profissionais de saúde acerca do cliente com enfermidade psiquiátrica crônica, contextualizando com a sua permanência institucional e o processo assistencial. Método: estudo qualitativo, com abordagem estrutural das representações sociais, realizada em 2013, em dois hospitais do Rio de Janeiro - Brasil, com 159 profissionais. Projeto aprovado pelo Comité de Ética em Pesquisa, pareceres nº 13/2009 e 53/2010. Utilizou-se a técnica de evocações livres e a análise com o software Ensemble de Programmes Permettant L’analyse des Évocations. Resultados: foram evocadas 795 palavras, com frequência mínima 9 e média 17. O rang das ordens médias de evocação alcançou 2.99.
