Introduction. Descending necrotizing mediastinitis (DNM) encountered problem of a high mortality rate. The increasing number of incidence and the need of immediate intervention DNM cases urge surgeons to manage early preventions and adequate therapy. The purpose of thisstudy is to find risk factors that correlate to the incidence of DNM in submandibular abscess patients. Method. Cross sectional study conducted enrolling all patients diagnosed with submandibular abscess that developed to DNM and treated surgically in emergency operating theater in period of January 2012 to July 2016 were reviewed. Mediastinitis which was not following submandibular abscess, those were not treated surgically or treated by other than the division of thoracic and cardiovascularsurgery, and those of pediatrics were not included on the study. The incidence of DNM was the dependent variable on the study; risk factors such as gender, age, body mass index (BMI), comorbid(s), leukocyte counts, and microorganism(s) were independent variables on the study. Results. There were 68 subjects enrolled on the study. The met the inclusion and exclusion criteria. Subjects characteristics are shown in table 1. Septic condition, surgical intervention, postoperative complications, and mortality are shown in table 2. There was no correlation between gender (p = 0.656), age (p = 0.763), comorbid(s) (p = 0.767 and 0.952). It also found that leukocyte counts, and cultured microorganism(s) showed no significant correlation. Conclusion. Not a single risk factor specifically correlatesto the incidence of DNM in subjects with submandibular abscess. Thus, so those with submandibular abscess have a same risk to have DNM developed.

The nation's productivity and competitiveness is one of the keys to the revitalization of vocational high schools currently being implemented in Indonesia. Revitalization of Vocational High Schools can be used as a solution to produce students who are modern, dignified, innovative and creative. This study aims to find out 1) Efforts that have been made by SMK in implementing learning innovations; 2) Implementation of quality-based productive innovative learning innovations at tourism vocational schools in the Greater Bandung area; 3) An innovative learning model that is used to improve the quality of graduates through productive learning at Tourism Vocational Schools. 4) The obstacles to the implementation of graduate quality-based innovative learning found in Tourism Vocational Schools in Bandung Raya. This research is descriptive research, taking place in Tourism Vocational Schools in Bandung Raya. The sample of teachers is productive teachers who are members of the Tourism Vocational High School MGMP in the Tourism Sector of Bandung Raya Regency, totaling 30 teachers. The sample of students is the students of SMK Binawisata Lembang who are taught by one of the MGMP teachers. The instruments used were questionnaires and FGD guidelines. Data were analyzed using quantitative and qualitative descriptive results. The results showed that: 1) Not all teachers mastered the 4K concept well; 2) Not all teachers are able to implement 4K in learning; 3) 4K learning based on graduate quality, shows that not all teachers apply quality awareness in both design, implementation and evaluation; 4) the obstacles that teachers feel when learning 4K-based innovation are: integrating 4K into learning, difficulty making syntax, developing learning methods; 5) the obstacles felt by students were that most students stated that it was not so difficult to complete 4K learning tasks. The implementation of graduate quality-based innovation learning with a 4K learning orientation still requires more in-depth study, both through FGDs, class observations and review of lesson plans.

This research provides an understanding of why the Discovery-Inquiry learning method as a means to deliver the classification of living things. This research uses a descriptive qualitative approach, descriptive by conveying clearly what is meant by discovery-inquiry and why it is appropriate when implemented in the material of the diversity of living things. Education is a planned and conscious effort to create a learning atmosphere and learning process in which students actively develop their potential, discovery-inquiry is an option in its delivery. Discovery-inquiry is a learning process where a concept is not presented in its final form, but students must organize their own learning by finding out these concepts. Meanwhile, the classification of living things classifies living things based on certain characteristics. So, of course it is very related to the discovery-inquiry method which requires students to play a greater role than the teacher by finding and ensuring the object under study whether it is in accordance with the theory or finding something new.

Rainfall is hydrology event that occurred seasonal in every year. There are two seasons occurred in Indonesia, dry season and rainy season. The analysis of rainfall characteristics plays a significant role to predict the rainfall occurrence and probability of flash flood. In this paper, rainfall analysis using Hydrognomon v.4.0 will provide hydrology data information, such as rainfall intensity and time series. The highest maximum rainfall of 526 mm (in 2010) has a return period of about 11 years. This means that rainfall of this magnitude can be expected to occur once every 11 years. The maximum rainfall of 425 mm (2013) has a return period of about 5.5 years, indicating a more frequent occurrence than the highest rainfall. Thus, it makes data trend rainfall with higher values tends to have longer return periods, indicating infrequent intensity. However, rainfall with lower intensity tends to have shorter return periods and occurring more frequently.
