Die vorliegende Bachelorarbeit behandelt das Thema das betriebliche Ideenmanagement. Das Ziel ist den Prozess zur Einreichung, Evaluierung und Umsetzung von Ideen weiterzuentwickeln und zu digitalisieren.
Um das Ziel zu erreichen, werden Primärdaten mit Hilfe von fünf qualitativen Interviews und einer quantitativen Umfrage mit 50 Mitarbeitern erhoben. Abgesehen davon wurden auch Daten aus der Sekundärforschung erfasst, deren Bestandteile die internen Unterlagen zum bestehenden Ideenmanagement dem Status quo, und wissenschaftliche Quellen sind.
In recent years, ISO, IFS, BRC and FSSC 22000 standards in the areas of quality, environment and occupational health and safety have been increas-ingly implemented in companies in various industries. The main focus of these developed standards are the processes. But the past shows that the factor human is another very important factor, which should be much more in the middle in organization. The new developed guideline has the human factor in the foreground. In particular, the attitude and awareness of occupational safe-ty and health protection in the behaviour of employees at all levels of the or-ganisation are at the centre of consideration.
Inspired by this approach, a group of experts from the fields of quality scienc-es, standardisation and certification as well as consulting for system-relevant companies in the agricultural and food industry came together to form a committee during the Corona crisis in spring 2020. The common goal is to develop a new standard. The first step is to establish criteria for a guideline.
and establish an evaluation system for several pillars of a House of Total Safety Culture (HSC) tailored to the entire value chains of the agri-food sec-tor. In addition, the essential building blocks of the guideline must be defined. The attitude of managers and employees, their behaviour and their compe-tence form the roof of the standard. The integrated management system with a continuous improvement process forms the foundation of the House of To-tal Safety Culture across the company in value chains. Qualification and communication are the main pillars and thus further elements of the HSC. Particular attention is paid to the fields of action of occupational safety and health protection, food safety, animal and environmental protection as well as sustainability and digitisation. They form the four inner pillars of the House of Total Safety Culture. The design of the respective certification levels is con-sidered as a “construction phase”. As part of the standardisation process, the coordination of the respective requirements for safety culture has not yet been completed. This article first provides an overview of the state of knowledge in relation to the established standards and norms of the agri-food industry with special consideration of the Safety Culture Ladder model. The procedure for developing and establishing the new guideline is then ex-plained. For this purpose, the composition of the expert forum is presented before the concrete steps to establish the guideline are presented. The model of the House of Total Culture is presented below. Building on this, the proce-dure for assessing the degree of maturity and possible concepts of continuing training are explained before the conclusion of this article.
This paper investigates four different mobile robots with respect to their drivingcharacteristics and soil preservation properties in an agricultural environment.Thereby, robots of classical design from agriculture as well as systems from spacerobotics with advanced locomotion concepts are considered to determine theindividual advantages of each rover concept with respect to the application domain.Locomotion experiments were conducted to analyze the general driving behavior,tensile force, and obstacle‐surmounting capability and ground interaction of eachrobot. Various soil conditions typical for the area of application are taken intoaccount, which are varied in terms of moisture and density. The presented workcovers the specification of the conducted experiments, documentation of theimplementation as well as analysis and evaluation of the collected data. In theevaluation, particular attention is paid to the change in driving characteristics underdifferent soil conditions, as well as to the soil stress caused by driving, since soilquality is of critical importance for agricultural applications. The analysis shows thatthe advanced locomotion concepts, as used in space robotics, also have positiveimplications for certain requirements in agricultural applications, such as maneuver-ability in wet conditions and soil conservation. The results show potential for designinnovations in agricultural robotics that can be used, to open up new fields ofapplication for instance in the context of precision farming.
BACKGROUND: Postoperative delirium (POD) is an acute and common complication after surgery that can increase morbidity and mortality. Few previous studies with inconsistent findings have examined the association of preoperative pain and POD. Our purpose is to investigate the association of preoperative chronic pain and POD.
METHODS: This prospective observational cohort study included 200 patients ≥ 18 years scheduled for elective surgery under general anaesthesia in a tertiary care hospital. POD was defined as meeting diagnostic criteria during the study visits (according to delirium screening tests and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), or by diagnosis of the responsible physicians. Chronic pain was defined as pain lasting six months or longer. Features of chronic pain were assessed with the German Pain Questionnaire, including the Depression Anxiety and Stress Scale-21 (DASS-21). Associations with POD were assessed using logistic regression analysis adjusting for confounding factors.
RESULTS: Thirty-nine (22%) out of 176 patients developed POD. Chronic pain was not associated with POD after adjustment for ASA physical status, duration of anesthesia and DASS-21 Anxiety score (Odds ratio [OR], 95%-Confidence Interval [CI], 2.216 [0.968;5.070], P=0.060). A subgroup analysis of chronic pain patients revealed that current pain intensity was higher in patients with POD.
CONCLUSIONS: Preoperative chronic pain was no independent predictor for POD. Current pain intensity was higher in chronic pain patients with POD. This indicates that certain features of pain might be influential. Further research is needed to examine different forms of preoperative pain and their possible influence on POD.
Hintergrund
Die Anämie hat eine hohe Prävalenz bei Patienten vor Hüftgelenkrevisionsoperation und ist mit einer erhöhten Komplikationsrate assoziiert. Die vorliegende Arbeit untersucht erstmals den Zusammenhang von Kosten, realen DRG-Erlösen und Falldeckung der präoperativen Anämie bei elektiven Hüftgelenkrevisionsoperationen.
Methoden
Für alle Patienten, die sich von 2010 bis 2017 an 2 Campi der Charité – Universitätsmedizin Berlin einer Hüftgelenkrevisionsoperation unterzogen, wurden Daten zu Patienten sowie Transfusionen, Kosten und Erlösen gesammelt. Subgruppen- und lineare Regressionsanalysen untersuchten die Falldeckung anämischer und nichtanämischer Patienten.
Ergebnisse
Von 1187 eingeschlossenen Patienten waren 354 (29,8 %) präoperativ anämisch. Insgesamt wurden 565 (47,6 %) Patienten, mit einem deutlichen Überwiegen anämischer Patienten (72,6 % vs. 37,0 %, p < 0,001), transfundiert. Kosten (12.318 € [9027;20.044 €] vs. 8948 € [7501;11.339 €], p < 0,001) und Erlöse (11.788 € [8992;16.298 €] vs. 9611 € [8332;10.719 €], p < 0,001) waren für anämische Patienten höher, die Fallkostendeckung defizitär (−1170 € [−4467;1238 €] vs. 591 € [−1441;2103 €] €, p < 0,001). Bei anämischen Patienten nahm die Falldeckung mit zunehmender Transfusionsrate ab (p ≤ 0,001). Komorbiditäten hatten keinen signifikanten ökonomischen Einfluss.
Schlussfolgerung
Die präoperative Anämie und perioperative Transfusionen bei Hüftgelenkrevisionsoperationen sind mit erhöhten Behandlungskosten und einer finanziellen Unterdeckung für Kostenträger im Gesundheitswesen verbunden. Konzepte zur Behandlung der präoperativen Anämie (z. B. Patient Blood Management) könnten mittelfristig Behandlungskosten senken.
The influence of moderate electric fields (MEF) on thermally induced gelation and network structures of patatin enriched potato protein (PPI) was investigated. PPI solutions with 9 wt% protein (pH 7) and 25 mM NaCl were heated from 25 to 65 °C via OH (3–24 V/cm) or conventional heating (COV) at various come-up (240 s and 1200 s) and holding times (30 s and 600 s). Self-standing gels were produced but less proteins denatured when heated via OH. Further, SDS-PAGE and GPC measurements revealed more native patatin remaining after OH treatment. Scanning electron microscopy showed OH gels to have more gap-like structures and frayed areas than COV treated gels which resulted in lower water holding capacity. On molecular scale, less hydrophobic interactions were measured within the protein network and FTIR trials showed the MEF to affect beta-sheet structures. OH gels further showed lower rigidity and higher flexibility, thus, gelling functionality was affected via OH.
