Diagram Analysis

This study aimed to analyze the damage to the machine, look for the biggest trouble factor happen and the most important is the effect of the application of the concept of kaizen to skill up the performance of operators in CW machining maintenance division. In the analysis and handling of an engine failure, the authors use PDCA cycle (Plan, Do, Check, Action) and the application of kaizen to analyze it. From finding the highest cause of trouble that will be made the theme of improvement by collecting data on the check sheet engine trouble and Pareto diagram, analysis of existing conditions using 5W2H, causal analysis the occurrence of engine trouble using the fishbone chart, using the concept of kaizen, evaluation of the results, up to standardization and follow-up. From the analysis of damage to the machine and application FANUC machine kaizen concept, showed a decrease in engine trouble and the increase in skill up performance operator significantly, which is certainly very good impact in terms of engine performance. Of course the result is also impact both on the quality of the product that will be used by the customer

Early stage of engine valvetrain noise improvement involves the implementation of Design of Experiment (DOE) specifically the Taguchi methodology to identify the optimum valvetrain parameters which resulted in significant noise improvement. The parameters are consist of seven controlled factors such as cylinder head tappet bore diameter, mechanical tappet diameter, valve spring load, camshaft exhaust and intake waviness together with tappet exhaust and intake clearance. The confirmation run which was previously completed yields the valvetrain noise level at 67.07db SPL by 1 meter distance in completed vehicle during idling condition. In order to satisfy the final quality of the optimal valvetrain, a test is carried out to validate the performance curve on a dynamometer according to benchmark specification. The objective of the test is to validate the optimal valvetrain based on the experimental result which minimum manufacturing target shall be achieved to indicate that the engine is operated within its intended design. The performance test was conducted at the manufacturing plant on an eddy current dynamometer which runs for 11 hours. As results, the performance are within the standard with approximate increased by 6.9% as compared with baseline valvetrain and confirmed by several follow-up tests made on the improved valvetrain. In order to verify and address the main engine output of the optimal valvetrain, brake specific fuel consumption (BSFC) and emissions test results are then presented at the end of this paper.

Summary: The cathartic effect of suicide is traditionally defined as the existence of a rapid, significant, and spontaneous decrease in the depressive symptoms of suicide attempters after the act. This study was designed to investigate short-term variations, following a suicide attempt by self-poisoning, of a number of other variables identified as suicidal risk factors: hopelessness, impulsivity, personality traits, and quality of life. Patients hospitalized less than 24 hours after a deliberate (moderate) overdose were presented with the Montgomery-Asberg Depression and Impulsivity Rating Scales, Hopelessness scale, MMPI and World Health Organization's Quality of Life questionnaire (abbreviated versions). They were also asked to complete the same scales and questionnaires 8 days after discharge. The study involved 39 patients, the average interval between initial and follow-up assessment being 13.5 days. All the scores improved significantly, with the exception of quality of life and three out of the eight personality traits. This finding emphasizes the fact that improvement is not limited to depressive symptoms and enables us to identify the relative importance of each studied variable as a risk factor for attempted suicide. The limitations of the study are discussed as well as in particular the nongeneralizability of the sample and setting.
