ESTRO-HERO survey: Guidelines for equipment and staffing of radiotherapy facilities in the European countries: Final results of the ESTRO-HERO survey

Background and purpose: In planning to meet evidence based needs for radiotherapy, guidelines for the provision of capital and human resources are central if access, quality and safety are not to be compromised. A component of the ESTRO-HERO (Health Economics in Radiation Oncology) project is to document the current availability and content of guidelines for radiotherapy in Europe. Materials and methods: An 84 part questionnaire was distributed to the European countries through their national scientific and professional radiotherapy societies with 30 items relating to the availability of guidelines for equipment and staffing and selected operational issues. Twenty-nine countries provided full or partial evaluable responses. Results: The availability of guidelines across Europe is far from uniform. The metrics used for capital and human resources are variable. There seem to have been no major changes in the availability or specifics of guidelines over the ten-year period since the QUARTS study with the exception of the recent expansion of RTT staffing models. Where comparison is possible it appears that staffing for radiation oncologists, medical physicists and particularly RTTs tend to exceed guidelines suggesting developments in clinical radiotherapy are moving faster than guideline updating. Conclusion: The efficient provision of safe, high quality radiotherapy services would benefit from the availability of well-structured guidelines for capital and human resources, based on agreed upon metrics, which could be linked to detailed estimates of need

Aineettoman pääoman johtamisjärjestelmä ja raportointi teollisuusyrityksessä

Aineellisen pääoman johtamiseen perustuvasta taloudesta on länsimaissa siirrytty talouteen, jossa kehitystä ja kasvua saavat aikaan aineettomat voimavarat ja toiminnot, kuten innovointikyky ja osaaminen. Yritysjohto kokee kuitenkin vaikeaksi sovittaa yhteen aineettomien menestystekijöiden liiketaloudellisen tärkeyden ja niiden systemaattisen johtamisen. Tutkimusongelma käsittelee niitä kysymyksiä, joita aineettoman pääoman johtamisjärjestelmän kehittämiseen yleisesti liittyy. Case-tapauksena esitettiin aineettoman pääoman johtamisjärjestelmän laatiminen kohdeyritykseen, jossa käytettiin viitekehyksenä Tanskan mallina tunnettua aineettoman pääoman johtamis- ja raportointimallia. Tutkimusotteena käytettiin konstruktiivista tutkimusotetta. Tämän tutkimuksen tulokset vahvistavat aikaisempia tutkimustuloksia siitä, että suomalaiset johtajat kokevat aineettoman pääoman johtamisen tärkeäksi ja tarvitsevat siihen avukseen työkaluja. Lisäksi tämä tutkimus antaa tukea sille olettamukselle, että Tanskan malli soveltuu hyvin käytettäväksi aineettoman pääoman johtamisen välineenä. Myös Tanskan mallin käytännön soveltamista koskeva ohjeistus ja prosessimalli todettiin riittäviksi aineettoman pääoman johtamis- ja raportointijärjestelmän kehittämiseksi.

Ninety-day oral toxicity studies on two genetically modified maize MON810 varieties in Wistar Han RCC rats (EU 7th Framework Programme project GRACE)

The GMO Risk Assessment and Communication of Evidence (GRACE; www.grace-fp7.eu) project is funded by the European Commission within the 7th Framework Programme. A key objective of GRACE is to conduct 90-day animal feeding trials, animal studies with an extended time frame as well as analytical, in vitro and in silico studies on genetically modified (GM) maize in order to comparatively evaluate their use in GM plant risk assessment. In the present study, the results of two 90-day feeding trials with two different GM maize MON810 varieties, their near-isogenic non-GM varieties and four additional conventional maize varieties are presented. The feeding trials were performed by taking into account the guidance for such studies published by the EFSA Scientific Committee in 2011 and the OECD Test Guideline 408. The results obtained show that the MON810 maize at a level of up to 33 % in the diet did not induce adverse effects in male and female Wistar Han RCC rats after subchronic exposure, independently of the two different genetic backgrounds of the event

Desenvolupament d'eines informàtiques per a residències geriàtriques

L’envelliment de la població demana cada cop més centres especialitzats en geriatria en els països desenvolupats. Aquests mateixos països pateixen recentment una falta de personal qualificat en infermeria. Aquests dos factors es combinen i posen en evidència la necessitat de desenvolupar eines informàtiques que modernitzin les residències geriàtriques. El projecte que s’ha desenvolupat consisteix en una aplicació de gestió d’una residència geriàtrica amb una base de dades centralitzada en un PC des de la qual s’hi pot accedir a través d’una aplicació feta per PDA. La seva funció principal és poder agilitzar tota la repartició de medicació dins la residència geriàtrica, gestionant des de les pautes de medicació corresponents a cada resident, fins a un control d’stock. Consta, per tant, d’una aplicació per PC, programada amb Visual Basic i utilitzant com a base de dades Microsoft Access, i d’una aplicació per PDA, programada amb Embedded Visual Basic i utilitzant la mateixa base de dades creada per l’aplicació per PC. L’aplicació de PC proporcionarà als usuaris una gestió ràpida i còmode i, alhora, rapidesa i estalvi de treball si es vol fer un determinat manteniment a través de l’aplicació de PDA. En el manteniment de l’aplicació, però, no s’hi inclou el manteniment dels usuaris tot i haver un control d’aquests. En aquest projecte s’estudia com es desenvolupa una aplicació per PDA i com comparteix una base de dades amb una altra aplicació a través del sistema de sincronització PC↔PDA anomenat ActiveSync.

Designing features for supporting social interactions in online communities

This Master's thesis studies the development of interaction and socialization in online communities. A large number of online communities fade away even before they really get started. In many occasions the reason is that the community does not give anything new, or even if they do, the delivery does not satisfy the users. In this thesis guidelines were developed to help to see important things, which might be forgotten when developing an online community. The thesis goes through the characteristic of an online community and human behaviour related to them and also compares behaviour in the Internet and real life. In addition, usability is an important part of the online communities and thus it is also covered in this thesis. As a result of this thesis an 8-step guideline was developed to ease the design of an online community. Guidelines were also applied to two real life cases which are described as one part of this work.

¿Para qué sirven los problemas en la clase de matemáticas? = What is the use of problems in Mathematics lessons?

The results obtained in several yield tests, at an international level (mainly the famous PISA 2003 report, by the OCDE), have raised a multiplicity of performances in order to improve the students' yield regarding problem solving. In this article we set a clear guideline on how problems should be used in Mathematics lessons, not for obtaining better scores in the yield tests but for improving the development of Mathematical thinking in students. From this perspective, the author analyses, through eight reflections, how the concept of problem, transmitted both in the school and from society, influences the students

Development and validation of RP-LC and uv spectrophotometric methods to assay bromopride in oral and injectable solutions

A reversed-phase liquid chromatographic (LC) and ultraviolet (UV) spectrophotometric methods were developed and validated for the assay of bromopride in oral and injectable solutions. The methods were validated according to ICH guideline. Both methods were linear in the range between 5-25 μg mL-1 (y = 41837x - 5103.4, r = 0.9996 and y = 0.0284x - 0.0351, r = 1, respectively). The statistical analysis showed no significant difference between the results obtained by the two methods. The proposed methods were found to be simple, rapid, precise, accurate, and sensitive. The LC and UV methods can be used in the routine quantitative analysis of bromopride in oral and injectable solutions.

Development and validation of an UV spectrophotometric method for the determination of aliskiren in tablets

For determination of aliskiren in commercial samples, an analytical UV spectrophotometric method was developed and validate according to ICH guideline. The method was linear in the range between 40 and 100 μg mL-1 (r² = 0.9997, n = 7) and exhibited suitable specificity, accuracy, precision, and robustness. It is simple, it has low cost, and it has low use polluting reagents. Therefore, the proposed method was successfully applied for the assay and dissolution studies of aliskiren in tablet dosage forms, and the results were compared to a validated RP-LC method, showing non-significant difference (P > 0.05).

Line filter optimization in elevator use

The purpose of this thesis was to create design a guideline for an LCL-filter. This thesis reviews briefly the relevant harmonics standards, old filter designs and problems faced with the previous filters. This thesis proposes a modified design method based on the “Liserre’s method” presented in the literature. This modified method will take into account network parameters better. As input parameters, the method uses the nominal power, allowed ripple current in converter and network side and desired resonant frequency of the filter. Essential component selection issues for LCL-filter, such as heating, voltage strength, current rating etc. are also discussed. Furthermore, a simulation model used to verify the operation of the designed filter in nominal power use and in transient situations is included in this thesis.

Generic and professional caring in a Chinese setting: an ethnopraphic study

The objective of the present study is to describe the cultural care practices, meanings, values and beliefs which form the basis of caring in a Chinese context. The research has its starting point in a caring science perspective and a qualitative research approach with interpretative ethnography as methodological guideline. The theoretical perspective is formed by elements of the theory of caritative caring, developed by Eriksson, and the theory of Culture Care Diversity and Universality, developed by Leininger. Previous research of suffering, culture and caring is described and also a presentation of actual transcultural nursing research as well as a presentation of the social structure dimensions of Chinese culture is included in the theoretical background. The empirical part includes patients and relatives, nurses and Hu Gongs as informants. The data collected are analysed based on Geertz’s idea of forming “thick descriptions” through examining the “what, how and why” of people’s actions. The findings show that the family has a prominent position in Chinese caring practices. The patient plays an unobtrusive role and a mutual dependence between the patient and the family members is evident. The professional nursing care is an extended act which includes the family in the caring relationship. The care practices of the Chinese nurse are characterized by great professional nursing skills. Suffering is described by the informants as being caused by disease, pain and social circumstances. “Social suffering” is described as worse than physical or mental suffering. Culturally competent and congruent care is a prerequisite for avoiding cultural pain, imposition and blindness when caring for the suffering human being. The findings of the present study necessitate a broadening in caring theory to include the family in the caring relationship. A further conclusion is that a broadening in our perception and understanding of culture would promote the delivery of culturally competent and congruent care. Suffering need to be seen as enclosed in cultural patterns of how it is expressed, interpreted, understood and relieved. Care and caring need to be seen as embedded in culture and the care practices values and beliefs have to be congruent with the cultural patterns where the care is provided.

Advanced orbital pipe welding

Since the introduction of automatic orbital welding in pipeline application in 1961, significant improvements have been obtained in orbital pipe welding systems. Requirement of more productive welding systems for pipeline application forces manufacturers to innovate new advanced systems and welding processes for orbital welding method. Various methods have been used to make welding process adaptive, such as visual sensing, passive visual sensing, real-time intelligent control, scan welding technique, multi laser vision sensor, thermal scanning, adaptive image processing, neural network model, machine vision, and optical sensing. Numerous studies are reviewed and discussed in this Master’s thesis and based on a wide range of experiments which already have been accomplished by different researches the vision sensor are reported to be the best choice for adaptive orbital pipe welding system. Also, in this study the most welding processes as well as the most pipe variations welded by orbital welding systems mainly for oil and gas pipeline applications are explained. The welding results show that Gas Metal Arc Welding (GMAW) and its variants like Surface Tension Transfer (STT) and modified short circuit are the most preferred processes in the welding of root pass and can be replaced to the Gas Tungsten Arc Welding (GTAW) in many applications. Furthermore, dual-tandem gas metal arc welding technique is currently considered the most efficient method in the welding of fill pass. Orbital GTAW process mostly is applied for applications ranging from single run welding of thin walled stainless tubes to multi run welding of thick walled pipes. Flux cored arc welding process is faster process with higher deposition rate and recently this process is getting more popular in pipe welding applications. Also, combination of gas metal arc welding and Nd:YAG laser has shown acceptable results in girth welding of land pipelines for oil and gas industry. This Master’s thesis can be implemented as a guideline in welding of pipes and tubes to achieve higher quality and efficiency. Also, this research can be used as a base material for future investigations to supplement present finding.

Integration of microgrids into electricity distribution networks

Existing electricity distribution system is under pressure because implementation of distributed generation changes the grid configuration and also because some customers demand for better distribution reliability. In a short term, traditional network planning does not offer techno-economical solutions for the challenges and therefore the idea of microgrids is introduced. Islanding capability of microgrids is expected to enable better reliability by reducing effects of faults. The aim of the thesis is to discuss challenges in integration of microgrids into distribution networks. Study discusses development of microgrid related smart grid features and gives estimation of the guideline of microgrid implementation. Thesis also scans microgrid pilots around the world and introduces the most relevant projects. Analysis reveals that the main focus of researched studies is on low voltage microgrids. This thesis extends the idea to medium voltage distribution system and introduces challenges related to medium voltage microgrid implementation. Differences of centralized and distributed microgrid models are analyzed and the centralized model is discovered to be easiest to implement into existing distribution system. Preplan of medium voltage microgrid pilot is also carried out in this thesis.
