The Indonesian government has set the motor vehicle industry as one of the priority industries of the national interest, economic growth, and increased productivity. In order for the survival of a company is maintained, then the management should be able to maintain or even more spur increased performance. Various analyzes were developed to predict the beginning of the bankruptcy of the company. One analysis is widely used today is the analysis of Altman Z-Score, which this analysis refers to the financial ratios of the company. The purpose of this study was to analyze the bankruptcy of the automotive components companies that go public in Indonesia Stock Exchange year period 2011–2015. This study used a sample of four companies from the automotive components sector. Source of data is done by using secondary data. The data is processed by the method of the Z-score formula Z = 1,2X1 + 1,4X2 + 3,3X3 + 0,6X4 + 0,999X5. With the description of Z < 1,8 the company categorized into unhealthy/will be bankrupt, the value Z 1,8 < 2,99 the company is considered to be in the uncertain/grey area and the value of Z > 2,99 then the company is in a very healthy. In general, the results of these studies indicate that the four automtive components companies namely PT Astra Otoparts year 2011 value of Z = 14,67 year 2012 value of Z = 10,88 year 2013 value of Z = 13,90 year 2014 value of Z = 10,54 year 2015 value of Z = 4,94, PT Gajah Tunggal year 2011 value of Z = 5,72 year 2012 value of Z = 4,75 year 2013 value of Z = 3,10 year 2014 value of Z = 2,79 year 2015 value of Z = 1,58 and the average value of 2011-2015 periode Z = 3,59, PT Goodyear Indonesia year 2011 value of Z = 2,07 year 2012 value of Z = 2,44 year 2013 value of Z = 2,57 year 2014 value of Z = 2,02 year 2015 value of Z = 2,76, PT Indomobil Sukses Internasional year 2011 value of Z = 6,19 year 2012 value of Z = 3,99 year 2013 value of Z = 3,17 year 2014 value of Z = 2,59 year 2015 value of Z = 1,74. The average value 2011-2015 period showed 3 companies are in very healthy state and 1 company is in the uncertain/grey area.

The Cost

A low cost and reliable protection scheme has been designed for a three phase induction motor against unbalance voltages, under voltage, over voltage, short circuit and overheating protection. Taking the cost factor into consideration the design has been proposed using microcontroller Atmega32, MOSFETs, relays, small CTs and PTs. However the sensitivity of the protection scheme has been not compromised. The design has been tested online in the laboratory for small motors and the same can be implemented for larger motors by replacing the i-v converters and relays of suitable ratings.

Цель.Определить морфометрические и гемодинамические критерии возможности выполнения двухжелудочковой коррекции у новорожденных и детей первого года жизни с врожденными пороками сердца (ВПС), сопровождающимися гипоплазией структур левого сердца. Материал и методы. В период с 2003 по 2016 г. в НМИЦССХ им. А.Н. Бакулева было пролечено 56 пациентов первого года жизни со сложными ВПС, сочетающимися с гипоплазией структур левых отделов сердца. В зависимости от морфометрических и морфофункциональных данных пациенты были разделены на две группы: 1-я группа одномоментной двухжелудочковой коррекции (n29), 2-я этапной двухжелудочковой коррекции (n27). Средний возраст на момент первичного поступления составил 35,955,4 дня (от 1 дня до 7,5 мес), масса тела на момент первичного обращения в общей группе 3,81,1 (2,177,6) кг, площадь поверхности тела 0,240,047 (0,160,36) м2. Z-score митрального клапана (МК) на момент первичного вмешательства в 1-й группе составил 2,770,70 (0,84...4,14), Z-score аортального клапана (АК) составил 2,890,85 (0,58...4,5), индексированный конечный диастолический объем левого желудочка (иКДО ЛЖ) 21,33,99 (1635). Z-score МК на момент первичного вмешательства во 2-й группе составил 3,540,74 (1,55...4,70), Z-score АК составил 4,351,11 (2,63...7,04), иКДО ЛЖ 17,663,06 (1222). Всем пациентам были выполнены различные оперативные вмешательства, направленные на создание двухжелудочковой гемодинамики. Пациенты, умершие в раннем послеоперационном периоде по причине сердечной недостаточности, составили группу контроля (8 пациентов). Результаты. Если размеры (Z-score) кольца МК более 4,5, кольца АК более 6, выводного отдела ЛЖ более 6, восходящей аорты более 4, дуги аорты более 4, иКДО ЛЖ (мл/м2) более 15, отношение длины ЛЖ/ПЖ по продольной оси 0,8 и более, то оптимальным является выполнение одножелудочковой коррекции. Были определены гемодинамические и морфометрические показания к одномоментной и этапной двухжелудочковой коррекции. Выводы. У пациентов со сложными ВПС, сочетающимися с гипоплазией структур левых отделов сердца и обструкцией кровотока через левые отделы, успешная двухжелудочковая коррекция возможна не менее чем в 85 случаев.
