The making of removable denture is performed by a dental laboratory. To facilitate the identification, according to Kennedy classification, classes are divided onto groups, the Kennedy class I, II, III and IV. To suit with the needs of the dental laboratory tasks commonly done, priority are necessary for common cases and should to be taught to students of Dental Health Technology Diploma. In Surabaya, research of various cases of removable partial denture with the various Kennedy classifications has never been done before. This study was to analyze the pattern of service for the removable partial denture manufacture in dental laboratory at Surabaya (2011 – 2013). The research is an observatory analytic. The population is all dental laboratories located around the campus of the Faculty of Dentistry Airlangga University Surabaya. The sample was the whole population is willing to become respondents. Sampling by total sampling. The method of collecting data using secondary data from a dental laboratory in Surabaya from 2011 until 2013. The note is cases removable denture according to the classification of Kennedy that Kennedy Class I, II, III and IV. Also of note kinds of materials used to make the denture base that is heat cured acrylic resins, thermoplastic resins and metals coherent. The data is a compilation table charting the frequency until needed, then analyzed using cross tabulation. Mostly denture type is flexible type and the least is metal framework. Most cases by classification Kennedy is followed by class II class III and class II and more recently is the fourth. In conclusion, in 2011 and 2013 the manufacture of removable partial dentures according to the classification of Kennedy Class III is the most common in both the upper arch and lower jaw, followed by Class II, Class I and Class IV. In 2012 which is the highest grade III followed by class II, class IV and class I. The denture type most used is a flexible denture, followed acrylic denture and the last is the metal framework.

Our goal in this present study is to introduce new wavelet based methods for differentiating and classifying Class I and Class II PDZ domains and compare the resulting signals. PDZ domains represent one of the most common protein homology regions playing key roles in several diseases. To perform the classification, we developed two methods. The first of our methods was comparable to the standard wavelet approaches while the second one surpasses it in recognition accuracy. Our models exhibited interesting results, and we anticipate that it can be used as a computational technique to screen out the misfit candidates and to reduce the search space, while achieving high classification and accuracy.

Although a large number of bronze ‘razors’ have been found in these islands, the literature concerning them is very scattered, and there has been no attempt to synthesize the information concerning them. There are frequent references to the so-called ‘plantain’ (our Class I) form or to the ‘maple-leaf’ (Class II) examples with their suggested connection with Siculan razors, but there has been no detailed analysis of their chronological and cultural positions in the British Late Bronze Age. This paper attempts such a classification of the razors on a typological and cultural basis so that they can be fitted with greater accuracy intq their place in Late Bronze chronology.

The reliability of Angle's system of classification of malocclusion has been examined. Between-examiner errors were found to be high and there were also high within-examiner error levels in categorizing Angle Class II division 2 malocclusions. It is concluded that comparisons of the distribution of malocclusions in different communities, classified according to Angle's system, should not be made unless observations are made in each community by the same examiner. The usefulness of Angle's classification to both clinician and epidemiologist is questioned.

Hazardous Zone

According to the international standard, main problems lying in the process of hazardous zone classification were emphatically analyzed. The source of release was determined in light of its release frequency and duration, namely the continuous source, primary source and secondary source. Considering the effect of release rate, LEL, density, ventilation, obstacles, and meteorological conditions on the classification of the hazardous area, it could be found that the hazardous zone would expand as the release rate increased with lower explosion limit. The gas that was heavier than air covered larger hazardous areas than the lighter gas. Besides, ventilation might speed up the diffusion so as to reduce the scope the hazardous zone; obstacles prevented the diffusion so that concentration of partial gas increased and then the danger level increased; wind at high speed quickened the diffusion to decrease the range of dangerous area. Finally, explosion-proof electrical equipment was selected rationally according to the type of explosive gas and temperature group.

Treatment Complexity

BACKGROUND To provide efficient and well-planned orthodontic treatment orthodontists must be able to assess the type of malocclusion and the complexity involved in its treatment. Hence, the purpose of this study was to validate index of orthodontic treatment complexity (IOTC) as a reliable index to assess the treatment complexity in treating different malocclusion groups. METHODS A retrospective study with sample of 120 pairs of orthodontic study model consisting of treated and untreated cases, were collected and equally divided into class I, class II including both division 1 and division 2 and class III malocclusions based on Angles system of classification of malocclusion. Study casts were scored according to criteria given by the index of orthodontic treatment complexity and the degree of complexity is established for each of the malocclusion groups and the occlusal traits. RESULTS The Spearman correlation coefficients test shows that occlusal traits like overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite, alone significantly correlated with degree of complexity. Multiple regression analysis and one way ANOVA tests were performed for the three types of malocclusion and the test showed that in individual classes of malocclusion, the predictor variable (occlusal traits) significantly predicts the degree of complexity in class I and class II malocclusion cases, but not in class III. CONCLUSIONS Overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite correlated with degree of complexity. IOTC forecasts the degree of complexity in class I and class II malocclusion cases, but not in class III. KEY WORDS IOTC, Malocclusion, Occlusal Traits
