[ES] La buena gestión de la atención primaria como puerta de entrada al sistema sanitario condiciona el funcionamiento de la atención especializada y la hospitalización, lo cual repercute directamente sobre la salud de la población. La sostenibilidad del sistema de salud público implica que los servicios de atención primaria sean eficientes. Objetivo Desarrollar un modelo para evaluar la eficiencia en cuanto a actividad realizada y resultados de salud de las unidades funcionales (UF) de atención primaria del Departamento de Salud Valencia Clínico - La Malvarrosa en los años 2015 a 2019. Metodología Se han integrado las bases de datos de la Conselleria de Sanitat Universal i Salut Pública y el Departamento de Salud Valencia Clínico - La Malvarrosa para obtener para cada UF: características de la población asignada, actividad asistencial y recursos humanos de los centros y consultorios de atención primaria. El análisis factorial pone de manifiesto las principales diferencias y similitudes encontradas entre las UF y permite reducir el número de variables utilizadas para elaborar los modelos de evaluación de la eficiencia, de manera que no se pierda poder explicativo, y facilite la interpretación de los resultados. Se ha utilizado el Análisis Envolvente de Datos (DEA) con orientación input y output y rendimientos variables a escala para la evaluación de la eficiencia. Los inputs incluidos han sido las tasas por 10.000 habitantes de: personal facultativo y personal de enfermería (inputs no discrecionales) y coste farmacéutico; como outputs se han incluido las tasas por 10.000 habitantes de: urgencias hospitalarias, consultas externas, derivaciones, hospitalizaciones evitables, mortalidad evitable y el indicador de eficiencia en la prescripción. Urgencias, hospitalizaciones evitables y mortalidad evitables se consideran outputs no deseables. Y como variables exógenas se han incluido el porcentaje de población mayor de 65 y 80 años y un indicador de morbilidad (case-mix). Se han analizado las puntuaciones de eficiencia de cada UF según tres modelos. Todos los modelos incorporan los mismos inputs y diferentes combinaciones de outputs relacionados con: Actividad asistencial (primer modelo), outcomes o resultados de salud (segundo modelo) y actividad asistencial + outcomes (tercer modelo, en el que se incluyen todos los outputs). Cada modelo se analiza con y sin variables exógenas. Resultados Se han evaluado los tres modelos con sus diferentes especificaciones para identificar las diferencias entre ellos y ver cuál de ellos permite diferenciar más claramente la eficiencia de las UF, teniendo en cuenta variables de calidad, y las características de la población. Se ha obtenido la puntuación de eficiencia de cada UF y se han identificado las UF que forman parte de la frontera eficiente del grupo estudiado. Los resultados han mostrado que existen diferencias en las puntuaciones de eficiencia estimadas en función de las variables introducidas como outputs. Determinadas UF se encuentran siempre en la frontera eficiente o muy cerca, mientras que otras UF son siempre ineficientes. Por otra parte, cuando se consideran outputs de actividad asistencial, las puntuaciones de eficiencia de todas las UF mejoran y aumenta el número de UF eficientes. Se detecta que la puntuación de eficiencia de las UF desciende, en general, a lo largo del periodo evaluado. Esta disminución es más pronunciada cuando se incluyen sólo los outputs de actividad. Conclusiones Se han obtenido diferentes resultados en función del modelo utilizado. El DEA permite analizar las ineficiencias de los centros de atención primaria, aunque es necesario identificar los objetivos esperados de las UF, ya que la perspectiva de los análisis influye en los resultados. / [CA] La bona gestió de l'atenció primària com a porta d'entrada al sistema sanitari condiciona el funcionament de l'atenció especialitzada i l'hospitalització, la qual cosa repercuteix directament sobre la salut de la població. La sostenibilitat del sistema de salut públic implica que els serveis d'atenció primària siguen eficients. Objectiu Desenvolupar un model per a avaluar l'eficiència quant a activitat realitzada i resultats de salut de les unitats funcionals (UF) d'atenció primària del Departament de Salut València Clínic - La Malva-rosa en els anys 2015 a 2019. Metodologia S'han integrat les bases de dades de la Conselleria de Sanitat Universal i Salut Pública i el Departament de Salut València Clínic - La Malva-rosa per a obtindre per a cada UF: característiques de la població assignada, activitat assistencial i recursos humans dels centres i consultoris d'atenció primària. L'anàlisi factorial posa de manifest les principals diferències i similituds trobades entre les UF i permet reduir el nombre de variables utilitzades per a elaborar els models d'avaluació de l'eficiència, de manera que no es perda poder explicatiu, i facilite la interpretació dels resultats. S'ha utilitzat l'Anàlisi Envolupant de Dades (DEA) amb orientació input i output i rendiments variables a escala per a l'avaluació de l'eficiència. Els inputs inclosos han sigut les taxes per 10.000 habitants de personal facultatiu i personal d'infermeria (inputs no discrecionals) i cost farmacèutic; com a outputs s'han inclòs les taxes per 10.000 habitants de consultes, urgències hospitalàries, derivacions, hospitalitzacions evitables, mortalitat evitable i l'indicador d'eficiència en la prescripció. Urgències, hospitalitzacions evitables i mortalitat evitables es consideren outputs no desitjables. I com a variables exògenes s'han inclòs el percentatge de població major de 65 i 80 anys i un indicador de morbiditat (case-mix). S'han analitzat les puntuacions d'eficiència de cada UF segons tres models. Tots els models incorporen els mateixos inputs i diferents combinacions d'outputs relacionats amb activitat assistencial (primer model), outcomes o resultats de salut (segon model) i activitat assistencial + outcomes (tercer model, en el qual s'inclouen tots els outputs). Cada model s'analitza amb i sense variables exògenes. Resultats S'han avaluat els tres models amb les seues diferents especificacions per a identificar les diferències entre ells i veure quin d'ells permet diferenciar més clarament l'eficiència de les UF, tenint en compte variables de qualitat, i les característiques de la població. S'ha obtingut la puntuació d'eficiència de cada UF i s'han identificat les UF que formen part de la frontera eficient del grup estudiat. Els resultats han mostrat que existeixen diferències en les puntuacions d'eficiència estimades en funció de les variables introduïdes com a outputs. Determinades UF es troben sempre en la frontera eficient o molt a prop, mentre que unes altres UF són sempre ineficients. D'altra banda, quan es consideren outputs d'activitat assistencial, les puntuacions d'eficiència de totes les UF milloren i augmenta el número d'UF eficients. Es detecta que la puntuació d'eficiència de les UF descendeix, en general, al llarg del període avaluat. Aquesta disminució és més pronunciada quan s'inclouen només els outputs d'activitat. Conclusions S'han obtingut diferents resultats en funció del model utilitzat. El DEA permet analitzar les ineficiències dels centres d'atenció primària, encara que és necessari identificar els objectius esperats de les UF, ja que la perspectiva de les anàlisis influeix en els resultats. / [EN] The proper management of primary healthcare as the gateway to the health system determines the performance of specialised healthcare and hospitalisation, which has a direct impact on the health of the population. The sustainability of the public health system requires the efficiency of primary healthcare services. Objectives To develop a model to evaluate the efficiency in terms of activity and health outcomes of the functional units (FU) of primary healthcare of the Valencia Clínico - La Malvarrosa Health District in the years 2015 to 2019. Methodology The databases of the Conselleria de Sanitat Universal i Salut Pública and the Valencia Clínico - La Malvarrosa Health District have been integrated to obtain for each FU: characteristics of the covered population, healthcare activity and human resources of the primary healthcare centres. The factorial analysis reveals the main differences and similarities found between the FUs and makes it possible to reduce the number of variables used to develop the efficiency evaluation models, so as not to lose explanatory power and to facilitate the interpretation of the results. Data Envelopment Analysis (DEA) with input and output orientation and variable returns to scale has been used to assess the efficiency. The inputs included were the rates per 10,000 inhabitants of: professional and nursing staff (non-discretionary inputs) and pharmaceutical cost; outputs included the rates per 10,000 inhabitants of: consultations, hospital emergencies, referrals, avoidable hospitalisations, avoidable mortality and the prescription efficiency indicator. Emergencies, avoidable hospitalisations and avoidable mortality are considered undesirable outputs. As exogenous variables we have included the percentage of the population over 65 and 80 years old and a morbidity indicator (case-mix). The efficiency scores of each FU have been analysed according to three models. All models incorporate the same inputs and different combinations of outputs related to: healthcare activity (first model), outcomes (second model) and healthcare activity + outcomes (third model, in which all outputs are included). Each model is analysed with and without exogenous variables. Results The three models have been evaluated with their different specifications to identify the differences between them and to see which of them allows the efficiency of the FU to be differentiated more clearly, considering quality variables and the characteristics of the population. The efficiency score of each FU has been obtained and the FUs that form part of the efficient frontier of the group studied have been identified. The results show that there are differences in the estimated efficiency scores depending on the variables introduced as outputs. Certain FUs are always on the efficient frontier or very close to it, while other FUs are always inefficient. On the other hand, when healthcare activity outputs are considered, the efficiency scores of all FUs improve and the number of efficient FUs increases. It is found that the efficiency score of the FU generally decreases over the period under evaluation. This decline is more pronounced when only activity outputs are included. Conclusions Different results have been obtained depending on the model used. The DEA makes it possible to analyse the inefficiencies of primary healthcare centres, although it is necessary to identify the expected objectives of the FU, as the perspective of the analysis influences the results. / González De Julián, S.

所有權結構、支付制度與競爭係影響醫院績效之關鍵因子，本研究援用相關文獻之發現，推論出三項因素對醫院績效之關係，並以我國獨特之總額預算制度為研究對象，蒐集、串連與合併不同來源之資料，實證檢視衝量競爭與所有權結構對醫院營運績效與醫療品質之聯合效果。 台灣於民國91年7月實施醫院總額預算制度後，浮動點值制度之設計為醫院間引入了衝量競爭(即虛假價格競爭)，而結算後之點值則係反映出醫院間衝量競爭後之結果，醫院除了需面對支付點值所致之財務衝擊外，尚須面對自全民健保實行後，備受醫院詬病之核減制度之衝擊，因此，本文首先嘗試估算醫院受到核減與支付點值所致之財務衝擊程度。無論是國外或國內之研究，對於不同所有權結構醫院之績效表現是否有差異性，一直無法獲得一致性之結論，除了納入營運效率之績效指標外，本研究亦採用疾病別與醫院層級別之醫療品質指標來檢視不同所有權結構醫院之績效表現。更以考量核減與支付點值所致之財務衝擊程度，取代目前文獻僅以總額前、後之二元變數，評估財務衝擊程度對營運效率、醫療品質與財務績效之影響。最後，則是檢視總額預算制度下，醫院受到之財務衝擊度是否會縮小不同所有權結構醫院之營運效率與醫療品質表現之差距。 實證研究發現，不同所有權結構醫院之營運效率並未有顯著差異，但不同所有權結構醫院在某些疾病別品質指標(子宮肌瘤切除手術之住院超過7日機率與再入院率)與醫院層級品質指標(院內感染率與淨死亡率)表現上則有差異性；且公立或非營利醫院受到核減與支付點值之財務衝擊高於私立醫院，因此不同所有權結構醫院之行為與績效存有某些差異性。台灣的醫院在總額預算制度下，若受到之財務衝擊程度愈大，其營運效率會變差、醫療品質也受到負面之影響、財團法人醫院之醫務利益率與稅後淨利率也會降低，但現金流量比則會增加，故財務衝擊愈大，醫院之績效愈低。若同時考量財務衝擊度對不同所有權結構醫院之營運效率與醫療品質之聯合效果後，可發現財務衝擊雖然不會縮小公立(或非營利)醫院與私立醫院營運效率之差距，卻縮小公立(或非營利)醫院與私立醫院醫療品質之差距，故以台灣資料可部分支持「不同所有權結構醫院績效差距縮小之因素係競爭力量之崛起」之論點。 / Hospital ownership, payment system and competition are all key drivers to influence hospital performance. This research infer and depict the association of these three drivers from the related literature and empirically examined the effects of fictitious price competition due to the floating point-value system and ownership on hospital operational performance and quality of care by combing and merging different sources of data. Deduction rate of claim and the floating point-value system are the two controversial debates to the payment system. I attempt to estimate hospital financial pressures as precipitated by deduction rate of claim and floating point-value system. To investigate whether for-profit, not-for-profit, and government hospitals differ in operating performance and quality of care, five diagnose-level and two hospital-level quality indicators are selected. Different from prior research, the financial pressure is captured by hospital data instead of a binary variable (pre and post global budget) and I examine the effect of financial pressure on hospital operational efficiency, quality of care and financial performance. Finally, we test whether differences in operational efficiency and quality care among hospitals with different ownership forms will mitigate or narrow, as hospital financial pressure increases. The results show that for-profit, not-for-profit and government hospitals are far more alike than different in operational efficiency, but ownership affects not only the rate of readmission and the rate of the length of stay larger than 7 days of uterine myomectomy, but also the hospital-level quality indicators: the rate of nosocomial infection and hospital mortality rate. I also find higher financial pressure incurred at government or not-for-profit hospitals than for-profits hospitals. Given my findings, we conclude that hospital ownership status affect performance in terms of quality of care and financial pressure from rate of deduction and float point-value system. The study shows that financial pressure adversely affects operational efficiency and quality of care. As not-for proprietary hospital financial pressure increases, the profit margin and net profit ratio will decrease, but the cash flow ratio will increase. Nonetheless, deduction rate of claim and global budget has a negative impact on hospital performance. This research further considers the joint effect of financial pressure on difference between quality of care and efficiency of for-profit hospitals and the other two types. My results indicate that hospital financial pressure mitigates the difference of quality of care between for-profit hospital and not-for profit (or government) hospitals, but does not narrow the difference in quality of care between for-profit hospital and not-for profit (or government) hospitals. This finding partly supports that increased competition should force not-for-profit (or governmental) hospitals to be increasingly similar to their for-profit counterparts.

This diploma thesis deals with efficiency of heat sources and indirect heating of hot water. First part of this thesis is about heating of hot water, particulary indirect heating of hot water and it is all summarized in theoretical knowledge section. Second part deals with central heating and indirect heating of hot water in four floor flat house. The heat source for this object is cascade of two gas condensing boilers. In this building there are mostly used panel radiators. In the last, third part, I experimentaly deal with operational efficiency of heating sources with heating of hot water.

The topic of this diploma thesis is the operational efficiency of heat sources. The work had several goals. The first was to determine the efficiency of the wood boiler according to available calculation methods and to compare the methods among them. The second was to determine the difference in the performance of the flue gas analyzer and the real calculation. Further, to determine the efficiency of a boiler firing different wood species - spruce and hornbeam based on their properties and elemental composition. Experimental measurement of various operating states of effectiveness took place in an older two-generation family house, which was also the subject of the project part. Due to lack of project documentation, it was necessary to focus and plot the object. Afterwards, the building was thermally inspected and the design of the heating system and the reconstruction of the whole heating system was carried out. The project was developed in two variants for two different heat sources - a heat pump and a solid fuel boiler for heating and water preparation. The thesis deals with the technical report, the conceptual solution of the related professions, the evaluation of the heat source variants and the project documentation.

This work deals with the determination of the operational efficiency of solid fules boilers for their inclusion in the relevant emission class according to ČSN EN 303-5. Two steel boilers of the same manufacturer, type and performance but of different ages, were measured. The experimental measurments in the real operation of the boilers were carrien out during the combustion of two types of fuels, namely brown coal and spruce wood.The operational efficiency of the monitored sources was calculated from the measured data using both direct and undirect methods. The found efficiency of the boilers corresponds to the expected values, due to their construction, age and the way of using individual components and regulations. In the project part of this work there is a proposal of heating of the family house for the condition of the building before and after the insulation. The calculation was made for the solid fuel boiler and heat pump. The building is heated by radiators and floor heating. The design of the whole system, technical report and project documentation were prepared for each variant.

The aim of the thesis is to analyse how to measure an economic pillar of sustainable urban development when it is understood in terms of qualitative city development. This principly means achieving economic prosperity which does not lead to damage of the city areas and decrease the quality of life for its residents. This approach requires the creation of an appropriate set of indicators that will cover qualitative aspects of sustainable economic development. The first section summarizes existing approaches to the definition of sustainable development and ways of measuring both on the Czech and the international level. There are also defined basic characteristics of the urban development which are appropriate to express a qualitative development of the city. The second part is focused on existing ways in which sustainable development is measured, i.e. especially in the context of indicator sets. These are under detailed assessment which aim is to show how useful is to measure the economic sustainability from the qualitative point of view. In this part, the limits of using economic macro aggregates (especially Gross Domestic Product) is emphasized because there are still regarded as one of the key economic indicators of sustainable development. In the next part the thesis deals with the definition of economic prosperity and focuses on the characteristics typical for short, medium and long term perspective. Measurement of sustainable urban development in the short term is based on assessment of financial situation. From the medium-term point of view, it is crucial to assess how the city handles its property, i.e. mainly buildings and land. These property components are substantial for a further direction of city development. In the next section are designed indicators aimed at measuring the ability of the city to maintain a skilled workforce which is one of the most important conditions of long-term economic prosperity. The final theoretical part of the thesis is focused on how the long-term sustainable urban development is to be expressed in an economic way through the assessment of investments in urban infrastructure and its operational efficiency. The designed set of indicators is verified on case studies of three medium-sized Czech cities.

More and more capital is being directed towards the private equity industry. As a result, private equity owned firms make up an increasingly large share of the economy. Therefore, it is becoming more important to understand the nature of how the operational performance of firms change under private equity ownership. This study looked at how the operational efficiency in terms of EBIT-margin changed over a three-year period after a private equity acquisition in the Nordic market. The study found that companies which had an initial positive EBIT margin behaved differently from companies with an initial negative EBIT margin and therefore two separate models where created. It was found that in the case where the company had a positive EBIT margin before being bought by a private equity firm saw an average decrease in EBIT margin of 1.14% units. In the case of a firm with initial negative EBIT-margin a private equity acquisition led to an average increase in EBIT margin by 1.99% units compared to the reference data. This study thus shows that private equity ownership affects the operational efficiency of companies. Moreover, it shows that one should make a distinction between PE ownership in profitable growth cases and turn-around cases of inefficient companies and that the impact of PE ownership in terms of effect on operational profitability can be vastly different depending on the nature of the acquisition in this regard. / Private Equity industrin ser ökande inströmning av investeringskapital, vilket resulterat i att en allt större del av ekonomin utgörs av private equity-ägda företag. Därmed ökar vikten av att förstå hur private equity firmor påverkar sina portföljbolag under ägandeperioden. Denna studie undersöker hur EBIT-marginalen i företag förändrats över en treårsperiod efter att företagen blivit förvärvade av ett nordiskt private equity-bolag. Studien hittade en signifikant skillnad mellan hur företag med initialt positiv, respektive negativ EBIT-marginal påverkades under treårsperioden och två separata modeller skapades för att utvärdera effekten. Resultaten påvisade med signifikans att företag med initial positiv EBIT-marginal minskade sin EBIT-marginal med 1.14% relativt jämförbara företag efter ett private equity förvärv. För företag med initialt negativ EBIT-marginal påvisades med signifikans en ökning av EBIT-marginalen med 1.99% relativt jämförbara företag efter ett private equity förvärv. Studien påvisar därmed att private equity ägande har en påverkan på operationell lönsamhet och att den skiljer sig markant beroende på ifall företaget initialt är operativt lönsamt eller ej.
